Lincoln Eleanor Cross main body almost complete

lincoln eleanor crossWe have been following the progress of the carving of the new Eleanor Cross for Lincoln by sculptor Alan Ward. The main body of this historic new monument is now almost complete and Alan will shortly be beginning work on the slate wing and seating area around the base..

You can see that Eleanor is emerging from the stone. In my mind this is analogous to her re-emerging from oblivion after being destroyed by the Roundheads approximately 370 years ago.

It seems strange to thing that we have been covering this project on the blog with images and video whilst there will be no record of it being broken up all those years ago let alone of it being built, hundreds of years before that. I can almost feel the spectres of those involved walking around inspecting the statue making observations, or just quietly raising a ghostly eyebrow.

The original site of the Cross is lost although it is thought that it could be at the top of Cross O’Cliff Hill which stacks up when you think about it. The Church of St Katherines is at the bottom of this hill. The population of Lincoln at the time would only have been a couple of thousand people – a far cry from the busy town of today. The erection of the Cross would have been big news in those days. Let’s hope we can make a similar impact in 2014.

We don’t yet have a date for an official unveiling of the Lincoln Eleanor Cross but I certainly feel a party coming on. Perhaps recreate the drink that was on offer when the Cross was originally installed (I’ll have to check on that one as it may be just stuff like mead which is orrible and won’t play a part in any party of mine:) ). We certainly won’t be dishing out any gruel.

Lincoln based readers may want to make a mental note to revisit trefor.net periodically to look out for any announcement or by all means leave a comment and I’ll take that as a request to be notified. If you don’t want to go on public record re this just say so in the comment and I’ll keep it private. If you have previously commented this won’t work as these comments are not moderated in advance.

Hammock days

hammock panorama

Ah those crazy, hazy lazy days of summer, of wine and roses, the heavy scent of the flower filled border, a chilled bottle of rose, cream tea on the patio, the strains of Satchmo floating through the still air. Panama hat cocked at carefree angle.

The snooze on the hammock whilst listening to Test Match Special, waking up after an hour or so to find that not much has changed. The score has moved on a little. No more wickets. Chocolate cake in the commentary box. Thank you Mrs Abercrombie of Sevenoaks. Our Andy wins Wimbledon, again.

The stroll to the beer garden. Cold cold lager under the parasol. A dog flops its languid tail. The heat abates: barbecue time. Occasional burgers flipped, steaks sizzle, sticky sausages tanned brown, ketchup smeared faces wear satisfied smile, gather around the fire laughing, singing and playing the guitar until the light dies.

Leave the clearing up. Bed beckons but tomorrow never comes…

hammockSummertime, and the living is easy.  Get the gist?

Gymnasium etiquette and staying in the zone

lincoln uni gym

Last week I took the plunge and joined Lincoln University gym. Drastic measures are called for – the lifestyle in this networking game is too social networking oriented, and I’m not talking about online social networks.

Anthony took me through a 1 hour induction process measuring weight, Body Mass Index etc etc etc although they don’t pay much heed to BMI at the gym – too many muscular blokes there that render the measurement irrelevant. I can’t remember all the parameters they measured. All I know is that some improvement is called for. It’s been sometime.

So I’ve got a programme that lasts somewhere between 60 – and 90 minutes and I’ve now been through it 4 times in the past week including 3 consecutive days this week. We have had a bank holiday weekend in that time so there have been forces pushing back against the weightloss/fitness. By yesterday I’d lost 1.3Kg since the induction session which considering the bank holiday ain’t too bad.

Before anyone says anything Anthony tells me it’s ok to train every day as the weights programme exercises different muscles in a 3 day rotation.

Now the main thing about Lincoln University gym is that most of the people there, me apart, seem pretty fit. Course they are all about thirty years younger than me so no wonder. It is somewhat disconcerting seeing blokes not only doing chin-ups but pulling themselves right up so that their arms go straight down by their sides – aka gymnasts on the rings – I can’t explain it any better and didn’t think it would be appropriate to take photos. It’s a good job the gym has a high ceiling otherwise they’d be banging their heads on it.

The other reason for not taking photos is because of the extremely fit girls in the room. It’s hard enough not to appear to be staring without causing more of a stir by using the camera. This means you have to develop a survival technique. Be seen to be in your own zone. Not staring at others. It’s all about etiquette I suppose. Just sneaked in the selfie of me in the pic above.

This means plugging in earphones and generally staring straight ahead. In the gym nobody talks to each other. They all stare straight ahead, sometimes at themselves in the mirror, or they stare at weights, assessing which ones to use next, presumably. Obviously to participate in this enforced zonality one needs to have ones own sounds. I happen to have some good stuff on my phone – Donna Summer’s Greatest Hits, Abba Gold and other quality material that has stood the test of time. My selection is fairly limited though so after 4 sessions it has become quite repetitive. I’m going to have to get some new tunes.

In the meantime the gym does provide four channels of TV on a screen at each workstation (or whatever it’s called). Most of what’s on offer is either crappy daytime TV or quite naturally, music channels. The music videos are quite illuminating. I’m sorry if this is not news to you but a big percentage of them seem to feature semi naked women jiggling around on screen.

In my day we had  Pan’s People and Hot Gossip but they were tame compared to what seems to be standard fare nowadays. I dunno. To understand where I’m coming from you need to realise that my fave movie is Mary Poppins. Nuff said.

Yesterday I plugged in to the gym sounds and fair play they were upbeat enough to up my pace and get my pulse going – the exercise did that, not the videos. The hardest part about going to the gym is that I have to walk home afterwards. Up Steep Hill for those who know Lincoln. For those that don’t know Lincoln Steep Hill is about a 1 in 1 gradient, or at least that’s how it feels even without having been to the gym. It’s not called Steep Hill for nothing.

You will be getting periodic updates on my progress in the gym, the regularity of which will depend on whether there actually is progress. If there is none I’ll be keeping quiet but expect to hear something soon:) My only short term problem is that at the end of next week I’m off to the Genband Perspectives conference in Orlando which will involve a week of conspicuous over consumption. It is the US of A after all. Let’s hope the hotel has a gymnasium eh?

Stay tuned. Hear it first on trefor.net.

Rural Broadband — a Lesson in JFDI (Part 3)

Rural broadband service deployed by Tim Robinson has made a difference to his local community – Part 3

Readers who not yet read Part 1 and Part 2 of Tim Robinson’s post will want to do so now, whereas those who have done so and who are no doubt eager to plunge right in should get on with it!

The success of the farm project has encouraged us to deploy into other rural areas. For the less financially promising locations we have taken a very conservative approach to funding, generally getting most of the installation costs for new repeater sites paid for upfront by the very customers who are driving the deployment. This ensures our ability to remain profitable and also ensures a level of commitment from our customers. Also, early on we took the decision that all services would be provided on a one-month contract. People seem to like that. A lot.

We have so far chosen areas that that Big Telcos will have real trouble covering with FTTx but that we can easily reach from our existing backhaul. We are also deploying into a local business park that has particularly bad ADSL service Such facilities are a lucrative area for us and seem thus far to have been deliberately avoided by Big Telcos, but we cannot be complacent as they are likely to be targeted in the future. We have sought to be very supportive and provide a good level of customer service, and business users tend not to be lured by the promise of high speeds and free sport channels. People seem to like that. A lot.

Since 2010 nearly 100 customers have connected to the network. In answer to such demand, we have expanded from a single VDSL2 backhaul from AAISP to multi-homed Ethernet transit over VDSL2. More recently, we added an EAD fibre backhaul. Our VoIP service has been widely used by our customers as a way of reducing cost and improving audio quality, as even phone calls over 8km lines sound rather muffled in comparison!

Some random thoughts and lessons learned:

  • Don’t just sit there and moan at Big Telcos. Do something creative. Nothing will happen unless you do.
  • If you don’t ask, you don’t get. People are much more accommodating of having a rather ugly 60cm dish on their chimney than you might at first have thought.
  • Farmers and landowners are great to work with. They have a can-do attitude to most things, unlike the naysayers of Big Telcos and the local authorities. They also have cherry pickers to help with link tests, and 4x4s to pull you out of muddy fields.
  • It’s easier to seek forgiveness than (planning) permission. We are operating on the basis that our antennas are ‘de minimis’ and the local council have been extremely supportive of our service.
  • When FTTx becomes available, not everyone leaves. A lot of people actually have a strong dislike of Big Telcos and welcome the alternative!
  • Use a professional aerial contractor for all ladder work. You know it makes sense.
  • A bridged Layer 2 wireless network will eventually end in tears. Route, Route, Route!

Things that are holding back small ‘alt-nets’ from deploying more coverage:

  • There is no such thing as ‘BT Retail’, ‘BT Wholesale’ and ‘BT Openreach’. These exist only in the minds of the regulator and BT plc’s internal processes. They are all part of BT plc and they can juggle profit centres to suit their shareholders, keep the wholesale prices high and retail prices low. Until BT Openreach is physically and legally separated from the other two, there will never be a ‘level playing field’ in this market. I call upon the government to force the Openreach division to be hived off into a totally independent, Network Rail-like, not-for-profit company.
  • Cost of backhaul. With the incumbent monopoly charging for fibre backhaul in the way they do, there will often not be a business case for installing service to some of the more remote places – wireless represents the only sensible way of delivering the connectivity.
  • By all accounts, the BDUK government funding of rural broadband is an utter fiasco. The whole process has been shrouded in secrecy, deliberately restricted to BT as the only real participant, and is thus holding back our wireless deployments. This is because we as small operators don’t know where the taxpayer funded FTTx footprint is to be extended next. It’s like the government building a road but not telling anyone where it is going to be until the diggers arrive! Government funded FTTx is part of the national infrastructure and there should be total transparency of which cabinets will be upgraded, which postcodes are served by these cabinets, and which will definitely not be done.
  • Fibre business rates and proposed business rate liability on wireless internet antennas. These are not progressive taxes, and as such makes it hard for small telcos to invest in fibre or wireless infrastructure. I call upon the government to overhaul this iniquitous situation and instead find a way to raise funds in a more progressive manner, based on profit. Oh wait. It’s called VAT and Corporation Tax.

Wall on walk to work in Lincoln

part of old Lincoln Minster perimeter wall

Because I try and vary my route in to work each day I get to notice lots of different sights. I will have seen most of them before but it is only when you have the time to your own thoughts that you really take the sights on board.

This week I was merrily heading officeward when someone who had been hanging around the traffic lights in front of me looking a little shifty asked me for directions to the station. He was clearly not from ’round here and I set him straight. I was heading in that approximate direction myself.

Now I am a slow walker and this guy soon went on ahead but at the next junction stopped to adjust his hair in his reflection in a car window. He was obviously unsure of his way. I pointed in the same direction I had pointed a hundred yards back and off he went again. At that time I branched off and took a different route. He was almost certainly ok but it was a bit odd that he kept hanging back with me and played safe. Was he going to try and rob me? In my bag I had a container of pea and ham soup for my lunch. Would have been a nuisance had he pinched that:)

Lincoln is generally safe anyway. I assume he got to the station. Probably never see him again.

My branched off route took me past St Mary’s Prep School whereupon I paused to take these photos. Hidden Lincoln. This wall is perhaps 700 – 800 years old and has clearly had one or two modifications done to it in its time. It looks as if it forms part of the wall to the grounds of Lincoln Cathedral but I could be wrong.

In one sense the wall represents power. The power of the church. On the inside you were safe, part of the gang. The wall kept the riff raff out.  In some respects it performed the same job as my change of route. I wasn’t sure about that guy so I avoided him.

Now I’m safe in the office behind a door that requires a walk past the receptionist and a passkey to get through. The only riff raff are the other start ups in the same corridor. They probably think that of me:)

Today it took me about ten more minutes than is usual to get in to work. How so I hear you say. It was all down to the traffic. Pedestrian traffic. I bumped into five people I knew on the way down and stopped to chat to three of them. The only reason I didn’t chat to the other two was that I was already deep in conversation, sharing some witticism or anecdote, or in one case sympathising because she was on her way back from the dentist. You get it all when you walk to work.

Gotta go. Business to do, moves to make, trees to shake.

I leave you with a second pic cos I know you like that sort of thing.

The Bench

heavy duty 1 ton viceI just ordered a bench. A made to measure wooden job for the garage to be precise. To be even more precise it’s 1400mm  long, 580mm wide (deep?) and 1050 high with a 44mm thick top.

Every bloke should have a bench. I particularly need one because two Christmases ago I got a vice. It’s bloomin’ heavy and needs a solid bench to sit on. Never used it other than once last summer to straighten out some tent pegs. Just seemed the right thing to have. Soon my vice will have a permanent home instead of just sitting in its box on a shelf in the garage.

Once my bench is in place I will have to make sure I have all the right tools – circular saw springs to mind but I’m sure there will be others that I need. I will only find out when the bench appears and I know how much space I really have.

topbox arrangement in garageThe garage is undergoing a makeover, as they say on reality TV fix my house up and redo my curtains programmes. First thing I did was replace the extremely dim energy saving bulb installed by Mrs Davies some time ago but which gave off so little light that we needed a torch every time we went to look for something in the garage.

Then I bought a moveable bike rack from Halfords. They had sold out of the brand new ones so I got an ex display model for 25% off (I asked for 50% but hey…). It’s in perfect, “as new” , nick. You will also note from the picture that the top box has moved up the wall using an innovative hook and chain combination to maintain its position. Reg from B&Q, the guy who sold me the Makita drill, suggested the method and it works by golly. Thanks Reg. Works a treat.

Next up then is the bench which I am expecting to get delivered on Saturday if it is the will of a Greater Being (Postman Pat). In researching this post I looked up the manufacturer’s eBay shop. If you want to buy anything else made from wood he does it all. Products are named to work well for SEO. I list some of them here:

wooden bondage stocks fetish spanking
bondage cage fetish kinky fifty shades
Chicken Feeding Station, Field Shelter
2.4m x 1.2m work bench 8×4
garden planter seat bespoke sizes available
spanking horse whipping bench bondage kinky
bondage cross dungeon spanking furniture
solid wood floating wine rack
solid wood floating shelf shelves

Came as a bit of a surprise but hey. A bondage fetishist has to get his or her equipment from somewhere and what better material than a nicely sanded wood. I did think about asking the joiner what proportion of his sales were bondage products. Didn’t think it would be striking up the right kind of conversation somehow. Who can blame him though. We all have to earn a living. Adds a new dimension to the saying “where there’s muck there’s brass”. Innit. It would be interesting to see how he got into that product range in the first place. No it wouldn’t – stay out of there Tref 🙂

I’ll stick up a photo of the bench when it is in situ. I know some of you will be getting excited already. Pic of bikes in bike rack below – floor needs a bit of a clean – I think we will paint it when we put the bench in.

Rural Broadband — a Lesson in JFDI (Part 2)

Rural broadband service deployed by Tim Robinson has made a difference to his local community – Part 2

Readers who have not yet read Part 1 of Tim Robinson’s post will want to do so now, whereas those who have done so and who are no doubt eager to plunge right in should hesitate no longer.

More often than not it pays to keep your mouth shut, however sometimes it pays more to be a blabbermouth! Had I kept quiet about the VDSL2 connection my friend Dave and I jury-rigged from his house to mine I’d have had a 40 Mbit/sec internet service all to myself. Alas, though, I was unable to keep such a good secret. I told my neighbours, who were immediately intrigued and wished to know more. Significant help was offered in exchange for a slice of the pie, so we ran an ethernet cable to the next door neighbour, and a cantenna-based 2.4 GHz link across the road to the other neighbor, and needless to say they were both chuffed to bits. Looking back on it all now, too, I think it is fair to say that without their encouragement and loads of assistance that just might have been the end of the story.

The roof of my house has a bird’s eye view of large swathes of the town, and this inspired us to consider the opportunities that this might open up to serve to the broadbandless burghers of Basingstoke. We decided after a couple of months that it was time to take things a bit further, to spread the net wider so to speak! With the addition of a cheap Mikrotik router, a Freeradius server, some clever MySQL queries from one of the neighbours, and a couple of rooftop antennas, I was able to get a basic configuration running that would allow us to bill users in a way similar to AAISP’s rather complex billing plan. And so, with just a few hundred quid’s worth of kit www.hiwifi.co.uk was born. It may not have compare to the American WWII effort at Iwo Jima, but it felt good nonetheless to get that first base station up and running, with the help of one of my pioneering neighbours. The first paying customers were all members of the Basingstoke Broadband Campaign who lived in my area and who were prepared to put their money where their mouths had been. And the rest, as they say, is history.

During all of this time the leviathan had not completely gone to sleep, as while I was extending the network out to Chineham and Beggarwood — which had even worse broadband speeds than we had over in our neck of the woods — BT and BDUK were plotting to use government money to overbuild my commercially deployed network and steal my customers. Well, that’s how it felt, anyway.

BDUK have since overbuilt a major part of my footprint, and it has been interesting as there was not a sudden and mass exodus from our 8 Mbit/sec service to VDSL2. As such, we had breathing space in which to look for ‘pastures new’, and we started to look further ‘afield’. (Puns very much intended – read on.)

Rather more recently, I was invited by Hampshire County Council to attend a Country Landowner’s Association meeting held in Winchester, to discuss rural broadband. The keynote speakers were Bill Murphy of BT and Maria Miller MP, (who was also Minister for Media Culture and Sport at the time), and needless to say the meeting did not go particularly well for either of them (though the lunch was quite good). There was a lot of animated discussion and, being a member of the awkward squad, I asked a few pertinent questions from the floor.

After the meeting a farmer and his wife approached and told me their long and sad tale. He had a load of farm buildings he’d converted into industrial units, and BT did not have enough copper to provide phones to all of them. The lines that did exist extended 8km to the exchange, too, so broadband was slow and flakey. Word on the street was that one tenant had been quoted £12,000 in excess construction charges to get one analogue line installed, and the farmer was having trouble letting some of the units as a result. He asked me the question I was waiting for: “Could I do anything to help?”

We looked at Google. I told him there was a problem in the way, that being a huge hill that blocked line of sight to his farm from my house. The response to that will forever remain ingrained in my mind. “That’s not a problem. That’s MY hill! Why not stick a repeater on top of it?”

The farmer took me around to his land and showed me what could be seen from where. He spoke to his neighbours, and quite literally elevated us and our survey antennas to new heights in his cherry picker, with cows looking on suspiciously from below. He generally oiled the wheels of progress in such a creative and ‘can-do’ way that within a few months I was connecting his farm, his home and the first of his tenants to our network!

Connected Like a Peasant

On a recent trip to France, I spent a day and a half in Chartres. I toured the cathedral there. I think there are strong similarities between the way we relate to technology today and the way people once related to technology in medieval Europe. This applies to emerging technologies, such as augmented reality and issues of net neutrality.

Chartres.01.205.town.

While in Chartres I learned that the latin word cathdra means seat. Thus, in medieval times the religious centers were the seat of power, which is how those domed buildings that housed the centers of power came to be known as cathedrals. We retain the same sense of the word when we refer to a seat of government, or a county seat – other places where domed buildings house the centers of power. These seats are the places where decisions are made on the behalf of other — is that enough foreshadowing on the net neutrality issue?

I picked up this etymology lesson from an old codger…er, scholar named Malcolm Miller. Or, rather, Sir Malcolm, as the gentleman has been knighted. Twice. Sir Malcolm is a British tour guide — a living legend, really — who has been working at the Chartres cathedral for 57 years. I didn’t know he was a living legend before I arrived in Chartres, however after spending 90 minutes listening to him talk I can see why he is so revered.

The nature of Sir Malcolm’s tour is to tell stories and he did just that, telling us about the meaning of the pictures in the stained glass. He explained that we can approach the elaborate stained glass like we would approach a modern day library. (Remember that the guy is 80 years old. He still thinks libraries serve a vital function. We let it slide. Library…Internet…same thing.)

Sir Malcolm began the tour by asking, “Would you go into a library and say, ‘Let’s meet for an hour and read all the books?’ No, of course not,” he continued, “and so to read all the history just in this church would likewise take a lifetime.”

He was explaining that the church was both a seat of power and a center of learning. That is, in a time when most people did not read or write, in a time when paper did not exist, the sculptures and stained glass of the church were the historical record of society. And who interprets the historical record? Of course, those who hold the money to sponsor the building of that historical record.

Chartres Map

By the end of 2014, according to Cisco research, the number of connected devices will exceed the world’s population — more than seven billion. Imagine that, a world in which digital devices on The Network outnumber humans. And how about this tidbit…by end of this year, 864 million phones and 103 million cars will support augmented reality (AR).

We are becoming more connected to information through our devices. Well, duh.

But is this new? I mean, sure, the mechanics of the digital devices are new, but I mean is it new to have society so interconnected through a mainstream channel of information?

Consider this: Today I can slip Google Glass on my head, hold up a can of creamed corn to read its bar code, and…voila! Google Glass will tell me the story of that can of corn (well, some unnamed database will tell the story). Calories, ingredients, nutritional value, etc., all that metadata tells me a modern story regarding that little piece of the external world. It’s metadata on the real world; the same as a stained glass window was, once upon a time.

I know it is one serious leap, comparing a web site or an Internet-enabled app to a stained glass window in a cathedral, but isn’t it the same relationship? Do we not look at all this metadata and information as stories of the “real” world? Isn’t that what modern technology is trying to provide us now – a way to better understand the world? That, and a means of connecting and communicating with people? That’s the modern version of stained glass in a cathedral.

Chartres.01.124.labyrinth

On the tour, I also learned something about how that stained glass got into those cathedrals. Sir Malcolm pointed out a couple of important features, such as the marks in the stone below each 30-foot high piece of colored glass — marks similar to logos — that identified who paid for that particular piece. Furthermore, our trusty guide said that the story told in each glass was the story that the sponsor wanted to have told. For example, the cobblers of the region paid to put in a stained glass that told the story of the Good Samaritan as well as the story of Adam and Eve’s fall from the Garden of Eden. The cobblers, for some reason, were trying to make a link between those two stories. Sir Malcolm explained that the story in the glass was a commentary on the Bible stories, providing material with which the clergy could instruct society. The commentaries were a way of informing society of two important things: (1) What was in the Bible, and (2) How people should behave, based on what was in the Bible.

So we see that it was not solely the church that interpreted reality. The merchants who worked with and built the church also had a say in the stories being told. These sponsors included guilds of cobblers, water bearers (think municipal water system), bakers, wine makers (think of all that wine purchased for the sacrament), cheese makers (blessed are the cheese makers), etc.

The church of medieval Europe was big business. He who told the story in those seats of power, called cathedrals, controlled the social structure.

Augmented reality? Net neutrality? Some big issues are on the horizon, matters that will change the basic structure of human society. Perhaps we can learn something from the history of the medieval church. Maybe, just maybe, we can take the time to recall the importance of the Golden Rule. You remember the Golden Rule, right? Go look it up — at the library.

Sell by dates taken to the extreme

activa yoghurt sell by date

Activia yoghurt introduce very precise sell by dates. Ya gotta laugh innit. I was just polishing off this peach flavoured Activia, eaten in tandem with a medley of both fresh and tinned peaches with fresh ripe mango (for the foodies amongst us) and for some reason it occurred to me to look at the sell by date. Might be the use by date. Not sure.

Doesn’t matter really. Sell by or use by, it was sufficiently far into the future to give me confidence that no bodily harm would come to me having consumed the pot. Tasty it was too.

Then I noticed that not only had Activia provided a sell by/use by date but they had included a very precise time on that day by which the yoghurt would have to be sold/used. This degree of attention to detail and the customer’s well being is laudible but must surely lead to confusion in the aisles of supermarkets up and down the country. At eight minutes to seven the yoghurt is ok but one minute later and you had better look out pardner. “Health and Safety” would be up in arms, on your back.

I also note that Activia, in English, likes to spell yoghurt yogurt. My standard way of checking a spelling is to enter the word in the google search bar to see what comes up. On this occasion both yog and yogh seemed to be ok although WordPress would appear to disapprove of yog. This seems unusual to me because having originated in the good ole US of A I’d have expected WordPress to go for the simple spelling aka plow, color et al.

Reading Activia labels can also be very educating. In this instance for example we can see that translations of peach are peche and perzik. I leave it to you to decide on the languages. Choosing incorrectly could lead to embarrassing mistakes caused by not being understood by waiters and shop assistants in countries around the globe.

Notwithstanding all of this the yo’ghurt I consumed was the last in the fridge and we are unlikely to have to face up to “the date” as an issue.Based on this sample size of one I’d say Activia yogs fly off the shelves making me think that the only reason they have “a date” on them at all is that bloke in H&S again.

I quite liked my Activia. It went well with the fruit medley and is a handy, easy to throw together dessert for the busy exec looking to squeeze in a quality meal between emails and blog posts.

Other yoghurts are available. This post was brought to you by Activia, Yeo Valley, Danone, Actimel, Shape, Muller, Yoplait, Nestle, Yakult and the Heathrow Eggs and Dairy Company.

Rural Broadband — a Lesson in JFDI (Part 1)

Rural broadband strategy- sometimes a community will haver to jfdi & sort their own solution

Trefor.net welcomes guest blogger Tim Robinson, Director of TxRx Communications Ltd. Tim’s post will run in three parts, beginning today and extending through to week’s end.

It is an onerous task to write a guest blog for one with as much credibility as @Tref, however this tale needs to be told, and the opinions herein need to be aired.

In the beginning there was ADSL. Historically, most of Basingstoke has suffered from bad broadband speeds. This all comes from having a telephone exchange in the town centre, and having most of the residential areas built in a doughnut-shaped ring around the centre of the town moving out 4-7km (as the copper runs) from the exchange. Thus, broadband was doomed before it was even a twinkle in BT’s eye.

As broadband became more of an essential utility and less of a luxury, campaigns were lead by frustrated people (including me) for whom 1.5 mbit was simply not adequate for doing one’s job, or keeping the offspring up-to-speed with the latest cat videos. We raised the issue with the Big Telco and others, but they all said nothing could be done. Unbeknown to us, though, there was activity between BT and our local council, and in 2010, there was a fanfare of excitement when it was announced that Basingstoke was going to be one of the first towns to get VDSL2 – colloquially (but incorrectly) known as ‘fibre broadband’.

The poor residents on the outskirts of Basingstoke breathed a collective sigh of relief, basking in the ‘knowledge’ that finally BT was doing something to help us. There was elation, and delight. Things were not all that they seemed, though, and the elation lasted only until the actual deployment plans began to be made known. That elation, in fact, quickly turned to disbelief, anger, and frustration. It seemed that BT were cherry-picking the cabinets in the already well-served Virgin Media areas close to town, plus a few others that met some secret internal criteria. The worst served parts of the town would continue to be unserved by the new technology! We were furious that BT had chosen to deploy VDSL2 into places that didn’t really need it, and omitting the places that did!

There were meetings. Beer was cried into. Letters to our MP written. There were Big Meetings with the campaign groups, the council, our MP and important people in BT. Above all, though, there was the spark of an idea. If some areas were to be served by VDSL2, why not pick up the backhaul from a VDSL2 connection and use wireless to provide internet service to the parts that were not included? Thus, this was the start of the JFDI* approach to broadband provision.

I live at the top of a hill. It transpired that a friend — let’s call him ‘Dave’, as it is after all his name — lived exactly 981 metres away, and was one of the ‘chosen ones’ set to receive VDSL2. With an element of stupidly unnecessary risk on Dave’s part, involving antics with a torch and a drill at the top of a three-section ladder, my friend and I determined that we had line of sight to his chimney from my house. Leveraging that knowledge, we managed to get an 80 mbit wireless link from Dave’s house back to what was to become a data centre in my garage. Our excitement was palpable, akin to the feelings of those pioneers who made the first London to New York phone call. Soon after, one of my neighbours lent me an old laptop, which we set up in Dave’s loft and from which we ran constant iperf and ping tests to see if our contraption would actually work.

Convinced over a couple of months that this wireless lark might actually fly, I took the plunge and ordered a shiny new phone line for Dave’s house from AAISP, along with a shiny new VDSL2 connection. (Installation was not exactly smooth, but that is another story.) Finally, once the connection was installed, I linked the Openreach VDSL2 modem straight into the wireless link and fired up a PPPOE connection at my house. Bingo! Suddenly what was 1.4 Mbit/sec on a good day became 40 Mbit/sec…and this was a very good day, indeed.

*To the uninitiated, JFDI stands for ‘Just Flippin Do It’. There are other alternative interpretations of JFDI but this is the one I am using.

Good Day Sunshine!

A few years back the following kernel of ridiculousness went in one ear, hung around long enough to make a mark, and went out the other: To capture enough solar energy to run the state of Arizona would require enough solar panels to entirely cover the state of Arizona. I don’t recall where I picked up that too-convenient statistic and I never confirmed it in any meaningful way (or any meaningless way, for that matter), but for years I have been guilty of bringing it into the conversation whenever the subject of solar energy has come up, mostly I must admit because the very idea entertains me no end. With this firmly planted in mind, over the past two weeks the subject of solar roadways (or perhaps I should write Solar Roadways, as it is a patented technology and that is the name of the company that hopes to use it to change the world) has come up in my presence no less than three times. In each case, the person bringing the juicy tidbit up for discussion swore up and down that they had heard that this new solar technology idea was quite revolutionary, making use of a solar energy collection methods and materials that are far better than what has commonly been known up to this point. The conversations were quite disparate, the people involved knowing each other only tangentially at best, and yet I figured the whole solar roadways…er Solar Roadways thing had to be some kind of an Internet meme…something I missed on Facebook and/or Twitter that was just making the rounds. It was only with the third mention, that I started to think I should burn a pixel or two to find out exactly what had the masses in a renewed solar energy rage.

First, I thought I should try to find some kind of pointer to the whole “Covering Arizona” thing (Coen Brothers fans, rejoice!). I googled and googled again. Then a third time. I also binged, and more than once. Nada. Now perhaps I overestimate my Internet search skills — I think I am Top 10 worldwide, and neither you nor your friend nor your friend’s brother can convince me otherwise — but even if I am only marginally adept (and I am far far better than that), I figure something would’ve turned up if there is or ever was any truth in that wonderfully wacky supposition. Alas…

So myth debunked. Next I decided to bring myself up-to-speed on solar energy technology. My inner science geek was born when I was but a wee youngster and it continues to live and breathe within. Unfortunately, though, I cannot say I have kept up with the evolution and progress of the energy sciences beyond the level of layman (computer-based tech is just too much fun, and there are only so many hours in a day/week/month/year/life). So off I went in search of education, and immediately I learned that the raw cost of solar energy year-to-year has been dramatically dropping for some time and continues to do so. In fact, new concentrated solar technology is said to be up to five times most cost effective than those ubiquitous standard flat photovoltaic silicon panels, putting it on par with oil and natural gas. Also, prototypes have achieved a concentration of solar energy that is more than 1,000 times greater than those panels. Go figure!

Solar Roadways

Relieved of preconception and far better informed, it was time to put my proverbial pedal to the metal and find my way to the now-seemingly-everywhere subject of Solar Roadways. Be it the result of a well-executed publicity blitz or a news confluence resulting from the $1 million the company has raised in recently-launched and still-ongoing indiegogo crowdfunding campaign (or both), Solar Roadways is the annoying buzz on the solar energy front that is currently tickling our collective ear (The Verge, CNN, The Washington Post, TechCrunch, The Daily Mail). The tech and company is the brainchild of Scott and Julie Brusaw, an Idaho couple, who since 2006 have been working to develop solar panels that can be installed on roads and in parking lots, capable of collecting massive amounts of clean energy from the sun. Able to keep the streets on which they reside free of snow and ice, Solar Roadways panels — which are made from ruggedized glass and can connect to each other via mesh network (in the event one fails, the system will notify its need for maintenance) — can also illuminate those streets and display warnings via LEDs. They also are said to be capable of cutting greenhouse gasses by up to 75% (this, of course, assuming that the tech hits worldwide critical mass). And perhaps the most appealing aspect of this astonishing-seeming technology, even more so than vast practical applications and inevitable economic benefits Solar Roadways can potentially offer? It LOOKS like the future!

Solar Freakin’ Roadways!

Privacy International versus GCHQ on PRISM

Since I last commented on the Edward Snowden affair, the inevitable has happened: the issues exposed have been raised in a judicial body in the United Kingdom.

Privacy International, a charity that campaigns to protect citizens’ privacy, has filed a case against the Foreign Secretary and GCHQ for the snooping alleged in the Snowden files (for those interested, the full case has been made public.

The Investigatory Powers Tribunal is the first and last judicial body in which such cases can be heard — there is no right of appeal to the Court of Appeal or the Supreme Court or any other such body, only to the European Court of Human Rights — which means we are in this one for the long haul as such cases are rarely expeditiously dealt with.

Prima facie, there’s nothing new in the case that we haven’t heard about from the Guardian newspaper or various media outlets, and therein lies the crux of the whole thing. Where’s the smoking gun? (An idiom invented by Sir Arthur Conan Doyle for the etymologists among you). The case appears to rely in great measure on revelations from Snowden in the press and doesn’t seem to provide, for example, a laptop with the alleged malware on it. The accusations are second hand — powerpoint presentations referring to capabilities, not a Flickr stream of unwitting selfies from usurped webcams. Essentially, in fact, the entire case is hearsay. In America, depending on the exact implementation in the specific State, it is generally inadmissible in its entirety, but following reforms of the UK judicial system in 2003 with regard to both civil and criminal cases, hearsay is admissible under certain criteria (which are not strenuous — the focus on what weight the court should give the evidence and not the admissibility). And, no doubt, that is a substantial factor as to why Privacy International chose to file a claim in the UK as opposed to the USofA.

Without writing an essay on the subject, and noting that I am not a lawyer but a regulation guru that spends a lot of time surrounded by them, it appears to me that the Edward Snowden revelations have a good chance of meeting the admissibility of hearsay criteria — good news for Privacy International, and bad news for GCHQ in terms of the first hurdle at least, with one notable exception. In order for it all to be admissible, the inability for the Defendants or the Claimant to call the Claimant’s key witness (Snowden) would have to meet certain thresholds.

Edward Snowden, to our knowledge, is not yet dead nor is he unfit to testify as a result of mental illness of physical disability. Whilst he is outside the UK, you can argue, it is not unreasonably practicable to secure his attendance because there is an extradition treaty with the Russian Federation where he is alleged to be currently residing (which takes care of the “cannot be found” argument too). Also, on the face of it, Snowden could be alleged to have been complicit or guilty of carrying out criminal acts under UK jurisdiction covered by the treaty. Thus, only “afraid to testify” remains, which is a valid concern, given how extradition might work with the USofA should Ed step foot on these shores to be cross examined or prosecuted.

I can’t help but wonder if this action by Privacy International is a double edged sword. Clearly it’s a strong attack on the UK government for their alleged involvement in Prism et al and it is good such actions and potential criminality is heard fairly in court, however its weight is somewhat compromised by the lack of a smoking gun and star witness. Regardless of your leanings on the subject, it is certainly something to watch.

Saturday Snapshot (24-May-2014)

Another Normandy weekend found La Famille Kessel welcoming a newbie to our oh-so-humble abode in Blangy-le-Château, which of course meant hitting the road. Though perhaps ‘hitting’ is too strong a term, as the rental car we have this time around is a Suzuki Celerio, a strange tiny beast of a vehicle that huffs-and-puffs at the slightest incline. Maybe ‘patting the road’ is more accurate. Also, it offers the strangest version of an automatic transmission I have yet encountered, with a three-stop gearshift that one pushes forward (into ‘R’) to go backwards and backward (into ‘D’) to go forwards. Neutral (‘N’), I am glad to say, is rationally located in the middle, which is just as it should be.

Manual Automatic

Also, if the driver prefers they can manually shift the gears by tapping the gearshift slightly to the left from A, and then tapping it up (into ‘M+’) to move to the next highest gear and down (into ‘M-‘) to downshift.

An automatic Standard? A non-standard Automatic? I have no idea what to call this new breed of auto (though a quick spin around the Internet just now seems to indicate it is “automated manual transmission”), but regardless of drive type moniker it is one awful ride. Setting that aside, the Celerio did perform its function, though with no élan whatsoever.

But enough about the car already.

On Saturday afternoon following lunch and a rainstorm (or two rainstorms…three?…this time of year the weather shifts so fast in Normandy it is a fool’s errand to try to delineate such) our band of four piled into the Celerio and headed for Honfleur, the remarkably picturesque port town that bumps up along where the Seine meets La Manche (that’s “English Channel” to all of you good mother-tongue English speakers out there). A regular visit we make with first-time visitors, I have to say that My Missus and The Boy and I really do enjoy making the 25-minute drive from Blangy to Honfleur a few times each year. Honfleur is beautiful, quaint and extremely charming and as expected this serves to make the place a little too touristy. Still, it is the perfect size for an afternoon walkabout and offers plenty of high-end shopping for the well-heeled, including a good amount of art galleries whose wares (and probably owners) are in some form of constant shift as well as some be-careful-what-you-touch antique shops. There are a number of interesting churches to walk through, a museum dedicated to the life and artwork of Honfleur favorite son Eugène Boudin (who had much to do with Monet becoming…well, Monet), and all manner of historical this-n-that surrounding the oh-so-postcardy harbor. Finally, Honfleur offers some truly marvelous grub to be had…great seafood restaurants, a few very nice creperies, and — of course — Alexandre Bourdas’s matchless Sa.Qa.Na).

I parked the Celerio — pushing the gearshift forward to back into my spot in front of Saint-Leonard — and shoehorned my group out of the car and onto the sidewalk. Recompressed, we began easing into Honfleur, and as always the town didn’t disappoint. Boats in the harbor, crushes of people packed into the cafés and restaurants lining the northern end of the port (all tourist traps that should be avoided at all costs, but which aren’t), and a truly awful rock group playing badly under a tent at the port’s southeastern corner next to the ubiquitous carrousel. All good.

2014-05-24 16.15.442014-05-24 16.30.36

We wandered over the drawbridge at the mouth of the harbor and walked up into the north end of town. Honfleur is one of those places where you just can’t help but repeatedly snap your shutter, even if you have a comprehensive souvenir album and have also already taken every picture there is to take (and many times over, at that).

“The way the clouds layer the blue sky over such-n-such church…wow.” “What a remarkable boat! And the flags!” “Isn’t that cute?”

At one point My Missus headed into the Musée Eugène Boudin with my visiting friend, and The Boy and I shot over to La Belle-Iloise to grab up some quality canned mackerel products. Soon we would all reconnect at the Celerio, and…well, just in case we got stuck inside the darn thing I wanted to be prepared!

Campaign for 3 day weekends – sign the petition

Campaign to make 3 day weekends permanent – petition

Another bank holiday yay with another chill out day in prospect. May have a bit of a potter this morning, game of golf this afternoon and finish off with a bbq. You might have something different in mind but by and large it’s all about enjoying yourself (the one exception being if you join the traffic jam to the coast).

It occurs to me that from around the end of April every weekend should officially be a 3 day weekend. Makes a lot of sense for the following reasons:

  1. It’s a good idea – people prefer holidays to working.
  2. A 4 day working week has the benefit that 4 is an even number. People working half days could have the option to work two full days instead of every morning or afternoon.
  3. It would make your annual leave allowance stretch further – have more opportunities to only have to use 4 days up to get 9 days off.
  4. It’s nicer to have time off in the summer.
  5. Transport networks get really clogged as people set off for a weekend away on a bank holiday. By effectively making every weekend a bank holiday people would not feel obliged to rush off and join a traffic jam as their weekends away would probably be more spread out.
  6. It would stimulate the economy be generating more bbq and misc gardening equipment associated sales.
  7. Ice cream vendors would also do well out of it creating even more jobs in this sector.
  8. We would avoid the risk of the few Bank Holiday weekends we do have of becoming a washout as there would be more of them thereby increasing the chance of nice weather.

Simples really. I may have missed one or two key points in my reasoning but feel free to add to the list by leaving a comment which in this instance is also how you sign the petition. Once we have 100,000 comments we will hand it to the prime minister for action. After all we are only a year away from a general election and he will be in a mood to do popular stuff.

We the undersigned call on the Prime Minister, Mr David Cameron, to make every weekend a Bank Holiday weekend starting from the last weekend in April and ending at the end of September when the weather starts to turn. You can do it Dave – you know you want to.

Most popular weather forecasts

most popular requests for weather forecast

Couldn’t help but notice the most popular places for weather forecasts on the Met Office site and it struck me that Birmingham was missing from the list. Wossgoinon I thought. Are the good burghers of Brum not interested in the weather? Isn’t the place the third most populous metropolitan area in the  United Kingdom?

Perhaps they don’t get any! Surely they must. Weather doesn’t just pass them by in Birmingham. Does it? It must get a mention on the TV weather forecast. You don’t notice when you look at the forecast because you are only interested in your own location or where you are going.

Maybe people don’t voluntarily go to Birmingham. I’ve been there three times in recent years. Once taking Kid2 for a looksee at their University and twice to August LINX meetings. LINX like to get out of London in the summer where it can get unbearably hot. So they go to Birmingham!

Stop right there. This isn’t a bash Birmingham post.  I’m sure there must be lots of good things in Birmingham – I’ve already mentioned the University which took me by surprise and impressed even though Kid2 chose Durham in the end. This is an analysis of the most popular places for weather forecasts.

Taking it from the top down the most searched for weather forecast is for London. This is completely understandable. The population of the metropolitan area of London, according to Wikipedia and the 2011 census is 11,699,601. Well it was when they did the census, not counting illegal immigrants and the homeless.

Most people that live in London have to commute to work and need to know whether to take an umbrella or sunglasses. London is also a very popular tourist destination and folk want to know what to pack before they turn up. Used the service meself for that very reason. V handy and generally reasonably accurate these days. You should know that I lost my Cisco brolly last time I was in London. Was there for an ITSPA workshop. Got the brolly when attending a corporate jolly with Cisco at the Olympics. It was a v handy compact number. Suspect it was nicked but hey…

Next up is Manchester, the second most populous metropolitan area.  On the one hand one might ask why the residents of Manchester bother looking up the weather forecast because allegedly it rains most of the time. This might be totally unfair (or it might not). Maybe they keep looking to see if there is a gap coming in the weather front so that they can get their washing out to dry. Forget it love. Buy a tumble dryer.

At this stage of the discussion it is worth noting that in the table of population sizes by metropolitan area, distilled from a more extensive list on Wikipedia, Manchester appears more than once. In fact several cities appear several times in the Wikipedia source because they split out subdivisions. Where possible I tried to merge the subdivisions to provide more compact reading. This was complicated by the fact that Liverpool and Manchester, both major metropolitan areas in their own right also appeared more than once as Manchester/Liverpool.

Drilling in to this showed that such areas contained reasonable sized towns in between the two major cities. I figured this was easily remedied by giving these reasonable sized towns their own identities in the table but after doing so for Warrington decided I couldn’t be bothered to do it for the others so gave up. What you have here is a mix of data of my own concoction:)

The population table below is therefore filled with dual populations who might prefer to be listed apart. Newcastle and Sunderland, Cardiff and Newport and Derby and Nottingham are particularly spring to mind. Tough taters.

Other notes are necessary. Reading is listed as the 8th most viewed weather forecast but doesn’t appear separately for its population. It is unfortunately subsumed by London. Why on earth Reading ranks for weather forecasts is as mysterious as why Birmingham doesn’t. Since I began this post I’ve added the most popular tourist destinations by rank (ref tripadvisor) to the table. At least Birmingham (for some peculiar reason) is on the list (must be the cricket) but Reading sure as heck ain’t. Notable omissions from the weather forecast rankings btw are Torquay and Llandudno who are both right up there as top ten tourist destinations.

Lowestoft ranks fourth for weather forecasts but appears neither in the population leagues nor the tourist top ten. Perhaps nobody actually lives in Lowestoft and it is merely a transit point for people catching ferries. And fishermen. I dunno.

Not worth dwelling on the rest of the data except to wonder whether Leeds and Cardiff shouldn’t be up there with Manchester for people wondering when the sun is going to come out. I leave the rest to your own interpretation.

Lasagne

Ingredients for lasagna if done properly don’t come cheap

Spent all afternoon yesterday preparing a lasagne. Used a BBC Good Food recipe –  classy if time consuming and well worth the effort. I’m not going to go through the recipe – you have the link.

Not particularly cheap to make mind you. Ingredients for lasagna involved a whole pack of prosciutto, a mozerella cheese and a handful of fresh basil. You can’t buy a handful of fresh basil. It comes by the pot at about ten pence a leaf (ok bit of an exaggeration). Was able to make use of the nutmeg and grater I got for Christmas. Its only other application is in a cheese fondue, to my knowledge. I like cheese fondues.

Also used some fresh pasta sheets prepared ably by Kid3 who not only made the dough but also operated the machine producing exactly the right thickness of pasta. The pasta, being home made, was the cheapest bit of the recipe. My only role was bolting the machine to the table – has to be solidly secured for the correct pasta effect:) If you’ve never made fresh pasta you have to have a go. It’s far superior to the shop bought stuff.

Quite proud of the result with the lasagne. Kids cleaned their plates and went up for more without asking. Also proud to say that most of my kids are good cooks as witnessed by the fresh lasagne.

Not sure about the heir. He eats mostly beans on toast supplemented by curry whenever we meet up. In fairness his monthly budget is about what I spent on ingredients for this meal, including a bottle of wine I ended up not opening. It’ll get used at the rainfall measurement tool bbq tomorrow (see yesterday’s weekend post). Nice bottle of shiraz from Waitrose. Lamb casserole today. Slow cooked in a rich tomato sauce with green and red peppers. Yum. Got some leeks in the fridge which I’ll make something with.

Seeing as it’s a long weekend if anyone can get me some food related posts I’ll stick em up, as long as they are clean:) Make sure you send photos.

Rainfall measurement technique #2 the bbq method

Latest in the trefor.net series on rainfall measurement techniques involves the use of a bbq to collect rain water.

The beauty of this method is that very little effort is involved. You leave a bbq out uncovered, accidentally or otherwise, and after it has rained go out and see how much water is in it.

This is a pretty rough and ready method and certainly not as accurate as or finely gauged as our first rainfall measurement technique using spectacles as described here. Typical problems are highlighted here:

  • The surface area of a bbq is typically quite large with most having a diameter of a good eighteen inches to a couple of feet. It is better to have a small diameter to height ratio (d/h) for improved accuracy (is there science to back this up? not sure – could just be a popular myth and if so I’m surprised I fell for it).
  • The ratio of diameter to depth is also going to vary especially with bowl shaped bbqs as many tend to be. Identifying the average depth of water can in these circumstances require a degree in mathematics. I’m not aware of an app that does this.
  • One also has to lookout for leakage caused by open, or slightly open vents that exist in some bbqs (often these are in the lid though – if this is the case with your own bbq then you can ignore this bullet point – note leaving the lid on the bbq makes it useless for rainfall measurement).
  • A bbq tends to be fairly easy to move. Make sure you don’t leave it under a tree by mistake. This can totally muck up your results as a tree will prevent the rain directly hitting the bbq, or Rainfall Collection Surface (RCS) as described by the Worshipful Company of Rainfall Measurement Professionals (WCRMP) (sorry no link available – they haven’t caught up with the times yet hence the lack of an app). The after drip of a tree is not uniform and can not in any way be considered representative of the preceding level of rainfall.

The technique itself is fairly simple. You just leave the bbq out in an uncovered area (see bullet above re trees) and after a suitable amount of time go and see how much rain is in it.

In an ideal world the WCRMP would have recommended standard bbq sizes for the job so that a measure of consistency can be applied (to the job of measurement – no pun intended). They have not done this (quelle surprise). In their defence this is partly out of a recognition that there are many different makes and shapes of bbq out there and they didn’t want to be seen favouring any one manufacturer.

In my mind this was a mistake and one that has meant that this method of measuring rainfall has yet to be widely adopted. You certainly don’t hear weather forecasters on the BBC (other services are available – it’s your choice) mention the bbq technique. Usually they only say whether it is going to be bbq weather or not. With the right equipment all weather is bbq weather.

Often at times like this I am asked whether I can recommend a particular make of bbq for the job. Ordinarily when recommending a bbq I’d say a Weber but in this case when the specific feature requirement of rainfall measurement I’d say that Weber wasn’t right. Webers usually come with the aforementioned vents in the base and have bowl shapes that are particularly difficult to measure. Also Webers are expensive and you wouldn’t want to reduce its lifespan by introducing the problem of rust.

You would be wrong to think I was therefore suggesting a cheap bbq where it didn’t matter if you had to throw it away after a year or two. Cheap bbqs tend to have millions (yes millions) of screws and nuts and bolts and take hours, days1 even to assemble. I can only offer our own solution which is a stainless steel bbq/firepit that can happily be left out all year round (though we don’t).

Our firepit has a flat bottom and regular if sloping sides that would make it easy to measure the overall d/h number fwiw. The pictures below show our bbq in action for rainfall measuring. The first shows the level of water obtained in one wet night earlier this week. The second photo shows a pretty much full bbq, a level reached by the end of the afternoon after that first pic.

This was one wet day. Now despite having taken the time to describe the bbq method for rainfall measurement I have to confess that I’ve not gone as far as calibrating our bbq for this purpose. All I can say is that it looked as if we had roughly one inch of rain overnight and maybe another couple of inches during the day. It would have been a simple matter to use a plastic ruler taken from a kid’s pencil case but I didn’t.

It is recommended that you don’t risk annoying a kid by doing this and go out and buy a ruler (6 inch clear plastic should do the job) that can be used specifically for the purpose, perhaps keeping it in a convenient spot together with your other bbq cooking utensils. By using the same ruler every time you maintain consistency and remember that the kid’s pencil case is not always readily to hand during term time.

The day of the photo shoot was in fact and as is plain to see a very wet day. Very wet days like this tend to cause traffic chaos in Lincoln and this one was no exception. There was an accident downtown (maybe a mile and a half away) and the traffic tailed back past our house. It was quicker for me to walk to the Morning Star for a swift un (Anne is away) than it would have been to drive.

It might in theory be possible to derive a measurement for rainfall based on the length of traffic tailbacks but this would be unreliable and be very difficult to calibrate. The traffic tailback method would undoubtedly be of interest to BBC weather forecasters as it would allow them to engage with the traffic and travel department. Cross departmental relations are encouraged within the Beeb as it is seen as providing better value to the taxpayer  by maximising the efficient use of existing resources. Also they at the Beeb like having their cross departmental team building nights out – self funded no doubt as such evenings if taxpayer funded would mitigate the benefits of the aforementioned efficiencies.

To conclude, this post has described a very good, easy to implement if inaccurate method for measuring rainfall using a bbq. The bbq is not currently in rainfall collection mode. I have it stood up on its side as I didn’t want to go to the effort of emptying it later. It’s all about choosing your moments and I don’t actually care whether I know how much rain has fallen anyway. Don’t let me stop you though…

1 When we first moved in to our house towards the end of the afternoon I nipped out to buy a bbq – it was a lovely sunny day and we figured it was the right thing to do. In the end it looked like it would take so long to put it together (millions of screws) that I had to go to Tesco and buy a couple of those disposable bbq trays that sort of do the job but are usually quite crappy. Ended up finishing the job the following weekend.

Lincoln Eleanor Cross – the story continues

Work on the carving of the new Eleanor Cross for Lincoln continues with artist and sculptor Alan Ward making good progress this week. When looking at the work being done by Alan you begin to understand why in historical times it might take years to carve a statue. By using power tools Al has been able to reduce it to a couple of months. There is an awful lot of stone to hack away at.

The following photos show some progress during the week. The first one to appear was taken a few days before the second. The third image is a close up of the wing, The others are videos with a short chat with Alan regarding this week’s work and a look at him in action smoothing out some of the wing

Gone Down to London to be the King

A visiting friend and I were slated for two days in London beginning Tuesday morning, however the night before My Missus came down with a painful malady I won’t describe here, so instead I put my friend on the Eurostar at the literal crack of dawn and returned home. Quite disappointed — I had been looking forward to hanging in London with my friend for over a month, and to catching up with other friends while in town, too (apologies once again, Tref, for not being able to connect for that beer) — I started pondering whether there was some way I could chase my friend up once my honey bunny recovered. Eurostar one-way ticket? Lessee. No. The price of that seat would be nearly double what I had paid for the original return ticket! Short hopper flight? The cost made that option a non-starter as well. Hitchhike? Really…come on. Then I remembered that back in my own personal Paleozoic Era (read: 2000) I had once taken a bus from Paris to London.

Not remembering the name of the bus company that offered service to London from Paris, I went all Bing on the problem and was soon staring nostalgically at the Eurolines website. Riiiiight. That was it. At the station at the end of the M3 train, whatevertheheck, at Galieni. I first came across an ad banner on the site that offered one-way Paris-London service for €18, shook my head in disbelief, and then very quickly came to disbelieve it when I saw the fine print (45 day advance purchase…my own, if it happened, would likely be closer to 45 minutes advance). C’est la vie. Regardless, the price was bound to still be quite good in comparison to the other options, so I punched my Departing From and Going To into the handy-dandy widget on the page and clicked Search.

€43. I was in business.

Eurolines typically runs seven buses from Paris to London, four of which I consider to be reasonable at my creaky 49 years of age (no overnight buses for me, outside of dire circumstance), and seeing as My Missus was seemingly coming around from her epically bad night-before and recovery morning I began focusing on the 15h00 bus (arrival at London Victoria at 21h30). At some point in the mix I thought I saw the word “wifi” in association with the Eurolines bus trips, and while that wasn’t a decision-maker I did find myself lightening to the prospect of a 6+ hour bus ride knowing I would be able to extend myself beyond the confines of the coach.
My Bus

As morning morphed into afternoon My Missus remained asleep, sloughing off the awfulness and catching up on lost winks. Just as I began shifting my bus plans to Wednesday morning, though, she popped up not-quite bright as a penny but somewhat shiny nonetheless. Before long my girl was breakfasted (at 13h30) and talking about going into work for the afternoon. I made a few noises about hopping on the bus to catch up with my friend, quickly received a sincere and truthful “Oh, you should definitely do that!”, and began once again to look forward to two days of London-style this-that-whatever.

13h54.

To AppleKory I went, fingers a-flyin’. I bought a ticket online for the 15h00 bus, printed the ticket out, threw a few essentials into my computer bag (like I had time to put a proper bag together…yeah, right), confirmed that my camera would be along for the ride (you want to know my camera’s name, inquisitive reader, I just know you do…information not forthcoming today), threw on a jacket I probably wouldn’t need and bolted.

14h05

Marcadet Poissonniers station, the M4. Change to the M3 at Réaumur–Sébastopol, direction Galieni. Short delays at many stations along the way, the tick-tocking clock in my head growing louder as said clock’s hands move ever-closer to 15h00. Pulling my ticket out of pocket to ensure Galieni is my target and discovering the small print that says — translated from the French — “Arrive at the station no later than 30 minutes before departure.” (it is 14h41 at this point, 19 minutes before departure and still two stops from the station). Uttering profanities, mental image of pounding the Metro train doors to hurry things along. Galieni. Dashing for the Eurolines station.

14h52. I am stepping on the proverbial skin-of-my-teeth, which has dribbled out of my mouth and under my shoes.

Check-in accomplished, I board the bus and find my seat. Sweat glands working? Check. Respiration at full capacity? Check. Skin temperature at maximum tolerance? Check. And then I start to relax. The on-board wifi can wait. I just want to feel the road moving under the bus wheels and exhale until Morpheus drags me off for a short doze. And soon enough that is exactly what happened.

Roughly an hour later I am awake. I am also hungry, having not eaten a thing since breakfast and not being able to grab any kind of a nibble at the bus station in my haste to make sure I was on the right side of the vehicle’s doors at departure. “Swallow it, Kory.”, I say to myself and I do. All I need is a little distraction, and if the Internet isn’t good for that it isn’t good for anything. I pull AppleKory out of her warm cozy place, fire her new self up (she is a whole other creature since I replaced her 1TB hard drive with a 2TB over the weekend), and start looking for trouble…er, the Eurolines wifi.

No dice. No joy. No wifi. On my bus “wifi” may as well have stood for “wishful fantasizing”, as there was no such service (the Eurolines website does say “free wifi**” with the ** indicating “**Available on most of our lines”…wishful, indeed). Thus I found myself relegated to whatever entertainment media I could find on the aforementioned 2TB hard drive. Another “C’est la vie.”

Eurotunnel

Compared to the Eurostar at just a little over two hours, even with wifi the six-and-a-half-hour Eurolines trip to London promised to be quite the slog. In truth, though, even without the wifi I would have to dig hard to slag it with anything approaching conviction. Comfortable seats, the consistent steady motion, travel companions without evident psychoses or hygiene challenges, a clean and usable waste management facility; for the price the Eurolines bus service has to be tossed onto the far too small “High Value” heap.

Following a very curious journey through the Eurotunnel — the driver drove the bus INTO a huge enclosed train (parking it right up behind another bus, with a truck then driven in and parked right behind us), which itself soon began to move — we were in the UK, barreling our way to London. Before long, Lewisham…passing by the Kia Oval (lights on, cricket match in progress!)…arriving at Victoria Coach Station.

I alighted with iPhoneKory in hand (still my not-so-smartphone, for now), knowing there had to be a Nando’s somewhere nearby.

Spark Notts business startup competition entry still open

spark notts business competitionI may not have mentioned but I’m a judge in the forthcoming Spark Notts business startup competition. Probably nobody else was available This is a great honour which I am of course looking forward to.

Prizes include a year’s free office space at one of Oxford Innovation’s Nottinghamshire Innovation Centres, business coaching and a huge package of business support prizes worth £40,000 in total. Worth avin.

I have always been somewhat sceptical of “business support” services but in reality lots of people starting up in business are doing it without having had prior experience. This kind of support can therefore be very useful, as is free office space. Better to have a workplace to “go to” rather than doing everything out of your spare bedroom which you should be letting to a lodger to help with cashflow in the difficult early stage of the game:)

The competition is open to folk in Nottinghamshire and there is still time to get your entry in – details here. Maybe I’ll get to see you.

Editorial footnote – I am quite often heard to say that I can be bought but on this occasion it is not the case. I have promised to be totally impartial and objective. Even if your idea is for a microbrewery or an Indian takeaway business.

Breaking news – I bought a Microsoft PC – 5 broken laptops in our house

asus windows8 laptopI bought a new Microsoft PC. It isn’t really breaking news because I mentioned it in a post last week. Ordinarily I’d keep quiet about such an acquisition because it is an embarrassment to have to resort to such retro technology. I only bought it because I have a single application that needs to run on Windows.

However I am prompted to discuss it because in our house 4 out of 5 Microsoft laptops have gone wrong in one way or another over the last few weeks.

Kid4’s screen went – he has now inherited my old work Dell laptop which being a Dell i5 he is happy about. Has to use an external sound card though because the internal one is broken.

Kid3’s screen is getting decidedly dodgy. Not the screen itself but the hinges are coming apart. Kid3 is starting to think the unthinkable and is looking at Macbooks (urggglergnffs££££).

Kid2’s screen broke a few weeks ago. This follows a repair job we had to have done to get her fan to work. She has seen the light and purchased a Chromebook. The Microsoft laptop now acts as a lampstand or some other similarly useful function.

Last week we have had a flurry of communications from Kid1, the heir, who needs his laptop for work but which now doesn’t work. Something has gone wrong with Windows 8 that prevents it from properly booting. His only recourse has been to spend £110 tvm on installing a new hard drive and a new instance of Windows 8.

My wife Anne’s laptop picked up the Chatzum adware crap and is looking pretty terminal. From previous experience with similar problems it isn’t worth trying to fix. It is either going to be totally rebuilt using a copy of XP sourced from an as yet undetermined location or like as not consigned to the great electrical scrapyard in the sky. The new laptop, used largely for that single application has been designated as hers for the purpose of performing occasional tasks that aren’t so easy on her iPad. Uploading stuff to eBay mostly.

The problems with Kids 2 – 4 laptops are down to build quality. They were all reasonably cheap purchases.  This is no excuse in a mass production world where quality should improve not deteriorate with time. You might say “what do you expect with cheapo laptops” but who is going pay top dollar for a teenager’s computer? And when I say cheap I mean £350 to £400 cheap. These low cost laptops were still almost twice the price of a Chromebook.

The Chatzum problem is in my mind a legacy of an old order, a decaying Microsoft bug ridden world which will eventually disappear from our communal consciousness. Ditto Windows8.

In the meantime life goes on, broken hinge or no broken hinge. I haven’t had the Chromebooks long enough to make comparisons but they are lighter, have solid state hard drives and just feel better and if one does break it isn’t going to break the bank to get a new one.

The age of the Windows PC is coming slowly but inexorably to an end. In a previous post I forecast that the death date to be sometime in 2022. Gut feel is that it is still on track although as the end approaches things tends to accelerate, like falling off the edge of a cliff.

What is interesting about that new PC-less world is that all applications will have moved online. The only reason Kid4 needs a PC is to run games. The day surely can’t be far off where all his games are available as a service online. Many of them already are. Another argument for having hardware is for video processing. I already use pixlr.com for my photo editing. Why shouldn’t there be an equivalent service available for videos. Probably already is.

Having everything in the cloud makes so much more sense from many aspects – reliability, cost and convenience. All I have to do is make sure that there is adequate connectivity. I realise that this will immediately raise the hackles of the rural broadband activists amongst you but that is a completely different discussion.

The PC is dying. Long live the cloud.

Is this the ugliest telephone?

Rob Lister is the all singing all dancing network engineer cum sys admin for LONAP, the London Access Point Internet Exchange.

And the award for the “Ugliest telephone of the year” goes to…

This was on a shelf with some pretty ugly telephones, this one stood out as the clear winner.

Designed by committee:

“No, let’s have the buttons represent a dial arrangement, that nobody has needed for the last 30 years… ”

“Kids won’t know what this means… Do they even use land lines? Let’s focus on the older users…”

“Okay. But it must have an answering machine crammed in there”

“Now we need another “dial” for the buttons that won’t fit on the first “dial…”

“Hmm. Then it needs a display. Let’s shove it awkwardly in the middle of that dial.”

“But it has to be cheap to manufacture. Hmm. We can’t have a nice ergonomic handset, just a basic plastic thing.”

“Yeah. So that’s all good. Lunch anyone?”

Marcadet-Poissonniers (both the M4 and the M12 make stops at the station, and I am on the former) is my hopping on point today, as it is the vast majority of times I make use of the Paris Metro, seeing as how the entrance is less than 50 meters from the Chez Kessel doorstep. Yet another stunning blue-sky spring day this mid-May Monday (ay-ay-ay), Paris really has been peacocking over the past week, splaying every one of her luminous feathers to maximum extension and effect. Not why we are here, though, to expound on the picturesque, so I’ll put the wanna-be poet back in his box and instead get wet with tech.

As people moving technology goes, RATP (Régie Autonome des Transports Parisiens) is at something of a crossroads. Still so much an analogue experience, the digital has been oozing in around the edges of Paris mass transit for some time, and recently it seems to have somewhat stepped up its game. For instance, whereas for literally decades the best a bus commuter could hope for regarding information on when the next bus might arrive at a particular stop was a posted published schedule, today Paris’s bus stops all offer updated electronic signs that indicate not only when the next bus will be stopping by but the next one after as well. And though this has been the norm in parts of the Metro for some time, the proliferation of such signage down there has markedly increased in recent years to now include every station (Kory Coming Clean: I did not travel to all of Paris’s 303 Metro stations to confirm ‘all’, but I do not recall the last time I stood waiting on a train platform lacking for the needed info). Still better than that, though, are the very new signs seen at Metro exits that indicate not only the bus lines that stop on the surface nearby, but also the number of minutes until the next bus on each of those lines will be arriving!

Train-BusNext Train

It’s all about synergy, baby! Well, that, and computers, databases, sensors, reporting software, and other such technological schrecktose that dates post-1975. That said, in spite of the obvious expenditures RATP HAS made in bringing their equipment up-to-near-date, It is hard not to shake one’s head in astonishment at their inability to configure the Paris transit system to issue individual tickets that can be used for hybrid journeys involving both train and bus. I think these days that ability is even available with the London Underground!*

Spot the difference – Brandon Butterworth, LINX award winner

Meet Brandon Butterworth, BBC Chief Scientist, supporter of LINX, LONAP and other internet engineering not for profit entities and all round good guy. Last night at the LINX 20th birthday bash Brandon was presented with an award. Can’t for the life of me remember what it was for but he deserves it whatever it is.

The two photos below are of Brandon proudly displaying his award. There are subtle differences – can you spot them. After I took one photo I noticed that Brandon had is serious look on so I insisted on a second with him smiling. Much nicer I’m sure you will agree. Can you spot which one it is, children? 🙂

The night before the morning after @routerfixer #LINX85

photo booth at LINX85 - 20th birthday celebration

Photo booth pic from the LINX 20th birthday celebrations at the Cumberland Hotel. A great time was had by all. Slight oddity, considering the internetty nature of the event, that the photo booth would only print out “polaroid” style pictures rather than being able to email me an electronic copy (cf the image of my eyeball by the opticians last week). This photo is a photo of a photo.

The two serious looking guys are Clive Stone and Steve Lalonde.

It’s funny to think that the last 20 years, the life of LINX, represent a substantial part of the total lifespan of the internet. ARPANET dates back to 1969. So if you were born before 1969 you pre-date the internet. You will be able to tell because when you first sign up to Facebook and need to choose your date of birth, any year prior to 1969 on the sign up page will involve scrolling down to get to the right number. They make it easy for those born in the “internet age” – their birth dates are displayed on the initial screen.

While I’m in a historical perspective mood and looking for milestones in my timeline it occurs to me that in In 1995, one year after the founding of LINX, I bought the Bill Gates book “The Road Ahead”. At the time this was a visionary work by one of the world’s most successful high tech entrepreneurs. We would have to be patient as the “information superhighway” was still some time in the future.

This is no longer the case. We have been streaming down the information superhighway for some time now, a fact reflected in the success and growth of LINX as an Internet Exchange Point.

I will be 72 years of age on LINX 40th birthday. I won’t be in the internet game although I trust I will till be an user (:). It’s going to be an exciting next 20 years. We no longer need Bill Gates to provide the vision. The vision is whatever your imagination can come up with (teleporting aside).

In the meantime Happy Birthday LINX, and all who sail in her (!?)

Wot? No Password?

UM Labs Ltd. Founder and CEO Peter Cox’s post is based on a presentation given at a recent ITSPA workshop on the risks of auto provisioning.

Everyone understands the need for security on the Internet. We all know the importance of using strong passwords and — painful as it may be — regularly changing those passwords. As such, would it surprise you to learn that there is one widely used Internet service that routinely provides sensitive information to anyone that asks without asking for a password or employing any other form of authentication?

The service I refer to is phone auto provisioning. If your company has an IP phone system (as most mid-to-large companies do) or if you outsource your phone system to an IP service provider, the chances are that your phones are using auto provisioning and possibly without using authentication. ITSPA has recognised the problem and is working on producing guidelines to address it.

One of the benefits of VoIP is that you can take a phone out of the box, plug it in just about anywhere, and it works. Of course, there is a lot going on behind the scenes. For instance, for an IP phone to work it must first be configured with such details as a phone number, the network address of the system it should connect to, and a password the phone uses to authenticate itself to the service provider or internal phone system. Calls cost money, so phones must be identified and authenticated when they connect to the service and when they are used to make calls. The problem is that the complete configuration for a phone is long and complex. It could include 100 or more parameters, for example:

	sips persistent tls:     1
	download protocol:       HTTPS
        sip line1 proxy ip:      xxx.xxx.xx.xx
	sip line1 registrar ip:  xxx.xxx.xx.xx
        sip line1 proxy port:    5060
	sip line1 registrar port:506
	sip line1 password:      xxxxxxxxxxxxxxxxx

Of course, nobody wants to have to type such information in, so this is where provisioning steps in. When a handset is connected it contacts a pre-defined provisioning server (just a specialised web server), identifies itself via its unique MAC address, and downloads its configuration. Simple! The problem, though, is that most provisioning servers identify the phone (particularly when hardware IP phones are connected) solely via its MAC address — a 12-digit value unique to each phone that is normally printed on the phone alongside the serial number.* As such, if a provisioning server gets a request for a MAC address it recognises the server replies with the complete configuration needed to configure the phone….and most provisioning servers DO NOT ask for a password or use any other authentication mechanism. Thus, anyone who knows or is able to guess your phone’s MAC address can download its configuration, including the password needed by the phone to make calls.

Distributing passwords to anyone who asks without some form of authentication is clearly a bad idea. And guessing MAC addresses is not as difficult as it sounds. All an attacker has to do is to connect to a provisioning server and try each of the 16.7 million possible addresses for a specific vendor, which may sound like a big challenge but which in truth is not. To support this point I recently wrote a very simple script to do exactly this in just 5 minutes. I then pointed my script at a service provider’s provisioning server and ran it using a restricted set of 1,000 address. Running on a £25 Raspberry Pi, my script took roughly 7 minutes to complete and returned the complete configuration of two phones including passwords. And as I had no way of knowing if any of the 1,000 MAC addresses belonged to phones connecting to the service provider, 1,000 is a good hit rate.

At a rate of 7 minutes to scan 1,000 MAC addresses it would take 86 days to scan the entire range of 16.7 Million addresses used by a particular phone manufacturer. Then, having done that, I could get the configuration — including the password — for every phone from a single vendor used by the targeted service provider. And what if I was not willing to wait 86 days? I could invest in faster hardware or spend a bit more time writing a more efficient script (or both) and easily complete the scan in a week.

The information that my script returns would be invaluable to an attacker, offering an easy route for call fraud that could leave the victim with a bill of tens or thousands of pounds. Thus, ITSPA’s initiative to address the problem could not be more timely.

*All systems connecting to a network, whether a wired Ethernet connection or a WiFi connection, must have a globally unique MAC address hard-wired in when the device is built. These MAC addressees are managed by the IEEE, with each manufacturer assigned a six digit prefix (A list of vendor prefixes is published at
http://standards.ieee.org/develop/regauth/oui/oui.txt). MAC addresses are base 16 numbers, so the remaining 6 digits can be used to create 16.7 million unique addresses.

The 3rd LINX router modelled by @neilmcrae and Keith Mitchell #LINX85

So you think you know your routers? This SPARCstation, chain.demon.co.uk,  was LINX’s 3rd router installed at Demon in Finchley (AS2529) in 1994. Before most of today’s ISPs were a twinkling of a Microsoft egg timer.

The SPARCstation is modelled by Keith Mitchel and Neil McRae who I realise don’t look old enough to remember those days but you would be wrong:)

The lads might be able to enlighten us re the throughput capability and route capacity of this box. It would be a far cry from the 100Mbps 100Gbps toys that Neil plays with nowadays at BT. It probably didn’t need to support more than 20 routes!

Neil is holding the router, Keith has the cup of tea. Note that the box is being held higher up than the cup of tea. That’s in case Keith drops the cup – safety in mind.:)

One also wonders at which point racks were standardised at the U dimensions they have today. Many an ISP had rows of tower PCs stood on metal shelves. Of course U’s these days are often Virtual.

VoIP not working over your broadband connection? We may have the explanation.

VoIP over broadband not working? It may be the router.

Routers provided by some major ISPs are preventing their customers from using VOIP services such as Skype.

For some time now members of the Internet Telephony Service Providers Association have been keeping a list of routers through which VoIP doesn’t appear to work. The routers themselves include functionality or elements of firmware that are either not user configurable or there are elements of the ISP service that mandate their router without an obvious means of using an alternative. This means that if a customer wants to use Over The Top VoIP services such as those provided by ITSPA members they usually can’t.

Unfortunately whilst this may well not be a deliberate act of anti competitiveness on behalf of the ISP it has the same effect as if VoIP was being blocked in the ISP network – interesting considering that some of these ISPs offer VoIP services of their own.

If you have such a router you probably can’t use Skype or any other VoIP service offered by the 100 or so independent providers in the UK. Whether this is deliberate or not is a moot point. The end result is that the ISP is affecting your ability to use the broadband service you pay for.

Most major ISPs are signatories to the Broadband Stakeholders’ Group Code of Practice and have undertaken to respect what is known as Net Neutrality or the promise not to favour any one type of traffic over another. This is a fundamental principle of how the internet works.

If an ISP provided routers over which 3rd Party VoIP services did not work whilst their own VoIP service continued to work perfectly well they would be flouting these principles. Effectively they would on the one hand be saying they are “good guys” which comes with obvious PR benefits whilst in practice being “bad guys”.

Dan Winfield, CEO of VoIP provider Voxhub says:

“This is an ongoing problem. It can affect customers that work from home at any time even if they have things up and running. A new update is shipped out by an ISP and effectively wipes out their phones. You can see the roll outs happening over a period of time as people call for support. The worse side of this is that customers get angry with us and we cannot do much. We cannot guarantee our service will work on home broadband as a result. When we roll out to offices, we always supply routers to get round the problem but this doesn’t work for home users.”

Not all ISPs are affected. It would be interesting to hear from any reader who has a broadband service but over which VoIP will not work.

Breaking news – the shed is finished

Breaking news – the shed is finished, or as finished as its going to get. Still a few bits of side panel need patching but it ain’t gonna happen.

The two images below represent the state of the shed first thing this morning, covered by a tarpaulin because it had no felt on it followed by the finished job.

Note Joseph who is sat on on top of the shed is modelling a LINX tshirt. Very appropriate for the job especially seeing as the next LINX meeting is this coming Monday/Tuesday. Big thanks to Joe whose B in GCSE woodwork is really starting to pay dividends. Made a lot more sense for me to send Joe up to do the dangerous bits. After all had I done it and fallen off I might have been badly hurt.

Joe’s hammering technique is top notch and worthy of an A grade. Examiner must have had a bad hair day or something.

In the interest of continuing with the mundane aspect of this “breaking news” I am pleased to announce that I didn’t need that second roll of felt after all and will be taking it back to Wickes straight after lunch. Hey £21 is £21. Jobs for this afternoon include taking Kid4 to the cricket nets followed by lighting the barbecue.
