My cycle commute is a little over 6 miles each way, and takes me through unlit country lanes for part of it. At this time of year, my working hours mean that both journeys are in the dark, particularly the homeward leg. I have been riding this route for about 11 years, and during this time I've used a Cateye Stadium 3 lamp (which is no longer available). This is said to pump out an equivalent to an 84W halogen lamp. It's given me good service over the last decade, and indeed its durability does seem good. It's always been a bit of a faff to take on and off the bike (it effectively has three parts: lamp, ballast and bottle battery). Charging the battery is a bit problematic, the charger that was supplied blew when I connected it by mistake to the output cable; it was prone to overcharge (so the lamp wouldn't light). The replacement charger couldn't be relied upon to fully charge the battery. Recently I was plunged into darkness en route to work when the battery ran out of juice. Time for a change, I thought.Browsing the Lumicycle website, one thing was striking: the modularity of the lighting systems. Initially, this makes deciding what to buy a bit complex, but it does mean you get to select the lamp configuration that is best suited to your needs. In my case I like to have something that really will illuminate the road ahead in the pitch dark of country lanes at night. I chose the high end LED4Si lamp.[caption id="attachment_1293" align="alignleft" width="250" caption="Lumicycle LED4Si"][/caption]This is a very compact four LED lamp, with an impressive array of features. The lamp unit has a single switch and a single power input. There is a multicolour LED indicator that indicates the brightness mode (of which more later) and the battery state.The switch operates by upward or downward presses, and is sensitive to short and long presses. This enables the user to select four different brightness levels and modes. At first this seems complex, particularly when confronted by the switching diagram in the manual (below), but in practice seems very intuitive. The base level that the unit is in when the lamp is turned on is very bright. A short downward press switches to the low setting. Alternatively, a series of short upward switch presses take you to high and then boost brightness levels. The first boost level is set to operate for 3 minutes before dropping back to high. This is particularly useful when negotiating stretches of dubious road surfaces or conditions. A long upward press takes the unit to permanent boost. Obviously the brighter settings use up battery power more rapidly. This arrangement is illustrated below (click for larger version). Trust me, it's easier than first sight might suggest![caption id="attachment_1289" align="alignnone" width="471" caption="Lumicycle switching diagram"][/caption]The beam pattern seems to be very even - more so than one might expect from a set of four super-bright LEDs. It's helped by the shape of the housing, which encourages a downward spread. The lamp unit itself has a simple quick release clamp that can be used on either standard or oversize bars. This makes it very easy to move the lamp between bikes - unless of course they have different diameter bars. Fortunately I'm a fairly conservative road cyclist, and most of my road bikes have standard bars!So, what sort of battery life does one get with such a high spec lamp? I selected the top option, the Li-ion bottle battery, because it seemed the easiest to attach to the bike (in the bottle cage) and because of its high charge capacity. The battery comes with a neat charger that seems well designed to avoid over-charging. A full charge is indicated by the LED indicator changing from red to green. The small (but very informative) manual is very clear on how to treat the battery - it is a general manual, so it also covers NiMH batteries as well.Run times (claimed by Lumicycle) range from 4.5h at boost level through 19h in mid brightness to 63 h in low. Using the flash mode gives a whopping 144h. On the very limited testing so far (I generally prefer not to let rechargeable batteries discharge too much), I've no reason to doubt these figures. Indeed since I commute using the lamp in high or medium with a short period in boost, I'm unlikely to see the battery discharge unless I miss several daily topups.So far, and on the basis of only a couple of commutes (four rides), I'm very impressed with the system, and highly recommend it. On the long term durability, I can't of course comment yet, but I do note that all the components are available separately. It's not a cheap system - the system reviewed comes in at £305 - though cheaper (and indeed more expensive twin lamp systems) combinations of lamps and batteries are available.

According to a report at road.cc (Valverde loses Swiss appeal, considers taking case to European Court of Human Rights), Alejandro Valverde has failed in his bid to get his ban overturned. The ban was for his apparent involvement in the Fuentes blood doping ring. A blood sample taken while he was racing in Italy apparently matches DNA in one of the bags of blood found in Fuentes' fridge, helpfully labelled 'Valv. (Piti)' - Piti supposedly being the name of Valverde's pet pooch (names of pets seems to have been the code names used).So, assuming the DNA work was done correctly, it would seem to be an open and shut case, and one wonders why Valverde will continue to take the case to ever higher courts. Of course doping athletes do seem to press on with delusional self-belief in their innocence beyond the evidence. Examples (not related to the Fuentes affair as far as I know) include Tyler Hamilton (and his vanishing twin), Floyd Landis, and the fabulous tale of Richard Virenque (who famously came clean and confessed in court). It's a shame they don't all take the rap for doping as openly as David Millar.Still, I have some sympathy for Valverde. Why have so few athletes faced justice over the Fuentes affair? And I don't just refer to cyclists. It doesn't seem right for only a handful for Dr Fuentes' clients get taken down, when all the others can just carry on.
The cyclingnews.com website released the results of the readers' poll on best technical innovation of 2010 (Electronic widgets voted Cyclingnews Best Tech Innovation - where you can see the full results).Somewhat bizarrely, pedal-based power meters top the list with 26.9% of the vote, edging GPS-enabled bike computers into second place. But isn't that a bit odd? After all GPS-enabled bike computers have been doing the rounds for some time. Indeed, I bought a Garmin 500 in the summer of 2010.However, we have two contenders for the pedal-based power meter category. Firstly Metrigear's Vector system. This has been widely discussed by Metrigear via their website and blog, detailing the ongoing product development, but it's not yet been released, despite slipping past several proposed launch windows. And since Metrigear has been snapped up by Garmin, not much information has been released.As for the Look/Polar confection, supposedly based on Look's Keo pedals, all I've seen has been some CAD mock-ups of what the pedal will look like.Yes, these would have been significant technical developments or innovations of 2010 - it's just that they weren't. Having said that, I will quickly join the queue to buy one (preferably the Garmin) when they do emerge...
As usual, I turned out for the club's New Year's Day 10 mile time trial on the F5d/10, which makes use of the new Stoke Hammond bypass. This year, eight hardy souls rode the event (but two as a two up team on road bikes with mudguards, I believe.This year's event benefited from above zero temperatures, but it was still rather cold and clammy with periods of drizzle. Immediately from the off, I noticed my additional bulk (accumulated as my mileage dropped off during December's snowy conditions) as the road rises to join the new dual carriageway. Annoyingly (having remarked on how light the traffic was earlier), there seemed to be a bit of an increase in traffic levels around the time we started event. I got a little slowed by traffic at the first roundabout (and again by a single driver at the penultimate roundabout), but to be honest the road surface at that roundabout is so poor I always take it rather cautiously.Once on the dual carriageway, I focussed on catching my minute man, which I did shortly after the turn. After that, it was a rather uneventful ride. However, I did feel rather awkward on the bike - it was the first time I'd been out on the time trial bike since the Duo Normand on 19th September, and not only did it feel both very twitchy in the steering but I certainly didn't feel comfortable in my aero tuck!I finished in 24:21, about 14 seconds faster than last year but beaten into second place by Lindz Barrall with a very fine 23, who increased his margin over me from last year's 10 seconds. Nevertheless, it earned me the New Year's Day '10' trophy for the fastest North Bucks Road Club rider.Results below the map...

2010 has seen some shifts in my usage of computer technology.After many months pooh-poohing the iPad (after all, what would I need an unfeasibly large iPod Touch for, anyway?), I had something of a change of heart. This was largely brought about by a trip to the USA for a conference - after a bit of thought, I picked up a 64Gb WiFi iPad, which proved an excellent device to cart about documents, pdfs, books, music and video. I've previously posted an overview of my favourite apps for the iPad, but this list just keeps on growing. Recent additions to the roster include:
- Air Display - this enables the iPad to be used as a second monitor for a Mac or PC, though sadly not Linux. It's pretty cool, but it remains to be seen how useful it is in practice.
- World of Goo - I recently bought the ludicrously popular Angry Birds for the iPad, but in my view, World of Goo (originally available for several platforms including Wii, Windows, OSX and Linux) is possibly the most charming app I've bought, beats Angry Birds hands down, and is a game format which works almost perfectly with the iPad's touch screen display. In my less well-guarded moments, I've been known to comment it is the kind of thing the iPad must have been invented for.
- Flipboard is a neat app which uses a neat and intuitive interface to let you rapidly and easily access news from a variety of sources, including Twitter, Facebook, Google Reader, and more beside. This is a useful an imaginative way to get at these feeds. I'd previously used The Feed to monitor Google Reader, but it seems to be rather flaky since the iOS 4.2 update.
2010 seemed to bring with it several directions for my web presence. My main Flies&Bikes website tended towards becoming a vehicle for reporting on my cycle racing, usually amplifying on the reports on club events filed at the North Bucks Road Club web site, but also reflecting on the open events I rode during the year. Interestingly some of these articles actually do seem to be read, with at least one time triallist over at Tempsford making a specific request that I note the weather conditions for a particular event had not been good - and this before I'd even changed after the event, let alone got home to write the report!I've been moving away from posting on politics and higher education at Flies&Bikes, and have moved that activity (which is always a bit sporadic) over to my posterous account. Similarly, my blogging on internet privacy has dropped in frequency, particularly after my departure from BT in favour of a more enlightened ISP a couple of years or so ago on the back of the Phorm phiasco. I do still blog about techy things that interest me (see tomorrow's post).Team Grumpy blogged sporadically, with brief flurries of excitement as our main event of the year came along, and more extensively with a report on our first visit to the podium (did anyone mention the Duo Normand?)Over at Wonderful Life, my activity increased with the establishment of the UK's first major foray into the wholly risible rehash of creationism, Intelligent Design, in the form of the Glasgow-based (but funded via Guernsey) Centre for Intelligent Design. This has provided considerable meat for the blog, particularly given that its three guiding lights appear to be deeply evangelical (and largely biblical literalists). I was invited to join the committee of the British Centre for Science Education (website, forum, blog), an invitation that I accepted and a role that I hope I'll be able to take part in more fully in the future.
The British Centre for Science Education (BCSE) is the leading anti-creationist organisation in Europe. We are a well established professional group dedicated to promoting and defending science education in the UK. The BCSE is run as a cooperative organisation by part-time volunteers with paid membership and a community forum where the general public can debate the key issues involved. It believes in the tools for everyone to think for themselves - Science, Education and Reason - and the outcome – Democracy, Pluralism and Liberty.We have become deeply worried about attacks on science education, particularly from creationists funded from the USA and Australia, and our campaign is dedicated to keeping all forms of creationism including Intelligent Design out of the science classroom in the UK.My twittering (#grumpybob and #teamgrumpy) has been sporadic, and often seems to fill the role of providing content to my FaceBook account. Website activity at the Northwood Wheelers and Team Grumpy websites has been minimal.
How did the 2010 time trialling season pan out?I approached the 2010 timetrialling season having made some changes in the organisation of my training. I had decided that I was no longer able to continue training in the evenings after work because I was getting home later due to work commitments. Instead, I was to be found pounding the turbo trainer in the garage at 6am…often dark, generally cold (sometimes extremely so!), but as it turned out a more effective strategy.Another change made at the outset of the training phase had been the adoption of a power meter on my turbo trainer. I have never been particularly impressed by the concept of power measurement in cycle training: too often I’d seen riders become obsessed with their power data (“Oh, but I rode a power personal best” is a common refrain after a mediocre performance). Because I was less than fully convinced of the value of power training, I chose the “budget solution” – a Polar CS600X with Power and Cadence, which I fitted to the rusty old turbo trainer bike. The Polar power meter works on chain vibration (apparently rather like a guitar string and pickup) – the system needs to know the chain mass and length – and seems to work reliably enough.To back this up I used Hunter and Coggan’s Training and Racing with a Power Meter, now in its second edition. This gives a pretty good overview of how to look at and analyse power data in the context of a training programme. Of course all these data are pointless without some means of dealing with the number crunching – for this I chose the excellent Golden Cheetah, an open source programme with significant capabilities. During the year I've been using it, it has seen significant development, reaching the version 2.0 milestone a few weeks before Christmas.A further hardware upgrade was the new time trial bike. For my 50th birthday, I received a Cervelo P3 frame and forks – I built this up mostly by transferring kit from the old time trial bike to this one, with a few new components. This machine has been a delight to race on, from 1st January to the Duo Normand in September.Pre Season TrainingMy preparatory training for the season generally begins in late October after a brief gap in cycling (at least intense cycling). I decided that I would be rather circumspect in how I made use of power data, and pretty much continued my usual programme, which fairly closely follows Pete Read’s Annual Manual (aka the Black Book). It’s probably inappropriate to detail this programme, as it’s undoubtedly copyright, but suffice it to say that it involves a steady base that gradually builds through progressive interval sessions to deliver one in good shape at the start of the season in late February or early March.The Black Book uses heart rate as a measure of effort: the main criticism by power meter afficionados is that this can be a poor reflection of effort due to “thermal drift”, and indeed this effect was quite clear in eyeballing the traces from turbo sessions ridden at a steady heart rate – generally power readings would start declining after bout 12 to 20 minutes. This was quite interesting to see, and when I moved into the season, I focussed on interval training for this reason.Of course, I did monitor my progress by analysing the quality of each session, and by periodically estimating my threshold power. However, the proof of the pudding was in the racing. How did my season go?Early season events - a mixed bagI turned out for the club’s New Years Day ’10’ and did a reasonable performance on a bitterly cold morning – it was about -4 Celsius. I think this result surprised me a bit, and it was probably the closest I got to Tony P’s time all season! Then it was back to the turbo treadmill before the NBRC club events got under way.As in recent seasons, the first four or so club events were held up at the Astwood circuit – these were rather uneventful. This account really deals with the open events I rode in 2010, so I’ll mostly ignore club events. The 2-up time trial outings with my regular Team Grumpy team mate Gerry are pretty rare nowadays since we live about 250 miles apart. It has to be said that this year our two traditional early season 2-ups were not especially successful.The Port Talbot Wheelers 2-up ’25’ is held on the first weekend in March on a course near Neath in South Wales – the course is about 50% dual carriageway and 50% severely undulating back road, and this year the weather was dry but bitterly cold. It’s actually rather a nice course, but not particularly quick. Usually at this time of year, I spend a considerable proportion of the race grimly hanging on Gerry’s wheel. This year I seemed to be setting the pace a bit more strongly. Unfortunately Gerry punctured about 3/4 of the way through the event and despite pressing on (at his behest), it was game over for Team Grumpy.Team Grumpy’s second 2010 outing was at the Icknield RC’s sporting course time trial in late March on a 30km circuit. Unfortunately the day before I’d punctured on the way home from a club event and had to walk a considerable distance. the consequence was that I’d got mud in my Speedplay pedal cleats. A tiny amount of mud, but enough to prevent me from clipping onto my pedal. So my race was over before it began – Gerry rode solo in the event (but of course his ride didn’t count). We rode no further 2-up events until the Duo Normand in late September, of which more later.Mid-season eventsThe first significant ’25’ was the Lea Valley ’25’ on the E2/25 over by Newmarket. This was the first of three outings on this course in 2010, and saw Tony and I sitting in his car by the HQ before the event apprehensively anticipating how we’d do – this being our first ’25’ of the season. In the end, we did rather well, and I did my best time in about 5 or 6 years, recording a 55:38. I never managed to rival the E2/25 times with performances on the F1!On the two subsequent outings on the E2, I recorded 55:29 on a spectacularly horrible day that saw many riders DNS, and a 55:43 while trying to take it easy the day prior to riding a ‘100’ on the F1. Actually, none of those events were on particularly ‘float’ days.That ‘100’ was the North Middx & Herts CA ‘100’, and by the time I’d plugged up and down the F1 for 86 of the 100 miles, I was getting distinctly bored. Unfortunately the finishing circuit was truly brutal, with a nagging headwind adding to the misery of cramping legs. I was riding unsupported, relying on a Camelbak for my nutritional provision. This was rather problematic as the Camelbak’s bulge interfered with the tail of my aero hat. Still, despite the previous afternoon’s ’25’ I managed to finish with a 4:25 – not as quick as I’d have liked, but not bad all things considered.‘10’s don’t figure very highly in my usual programme of open events, partly because there just don’t seem to be many locally, and partly because I prefer longer events. Anyhow, a good ’10’ time certainly seemed to be likely by the time I rode the Norlond CA ’10’ (25/4/10). This event was on the F1/10, and was on a particularly wet morning. By the time I reached the turn, I was closing on my minute man. Unfortunately just after rounding the turn, I suffered a puncture and had to make a rather soggy return to the HQ, pondering what might have been my best ’10’ in several years.It wasn’t until an evening event on the F20/10 (the Whitewebbs CC ’10’ on 3rd July) that I pulled off a decent ’10’ – a 21:05. Once again this wasn’t a particularly quick feeling evening, but the time was only 14 seconds slower than my all time best ’10’ – and my second fastest ever.The club’s designated ’25’ championship event was the Hemel Hempstead ’25’ on the F13/25 – the odd course that has traffic lights at a pedestrian crossing! The lights are marshalled, and anyone jumping the lights gets disqualified. I was the fastest of the three NBRC riders to take part, and did a respectable time for this not-very-fast course. Similarly, I was one of the few NBRC riders to ride at 50 miles this year, and I think the only NBRC rider to enter the nominated ’50’. My top 50 mile performance was at the Finsbury Park CC event on the F1, where I recorded 1:57:45, my best in the last five or six seasons.The Duo NormandThis was Team Grumpy’s seventh ride in the Duo Normand, and we’ve posted write-ups online (see flies&bikes and the Team Grumpy blog). Suffice it to say that while this wasn’t our fastest time, we did win our category (Corporate), had the glory of a motorcycle outrider, and climbed onto the podium to receive a glass trophy, a bunch of flowers and the all-important podium girl kiss. Well, we got the podium kiss once they'd realised we were cyclists and not a pair of old duffers who'd climbed onto the podium van by mistake!All things considered, 2010 was an excellent season: my entry forms will have 2010 times for 10, 25 and 50 miles. Sadly, I couldn’t quite get there at 100 miles (and there was no way I was riding a '12' this year!), but hey – not bad for someone just starting their second half-century! But what of our touring?2010 Summer TourThis year's tour once again saw us returning to the Hebrides, with a route encompassing several ferry crossings - visiting Barra, The Uists, Skye, Ardnamurchan and Mull. While a little cold to begin with, we got away with decent weather. Except, that is, for the time we spent on Skye, when it pretty much tipped down mercilessly. By the time we made it to Ardnamurchan, the weather was delightful. Unfortunately, that didn't last, with the final day's cycling from Tobermory to Oban being rather murky and drizzly. We stayed in B&Bs and Hotels, accommodation highlights being the Tigh Dearg Hotel in Lochmaddy (North Uist) and the Salen Hotel.Normandy 2010In September it was back to our stamping ground in Normandy - once again we took the trusty tandem for a spot of cycling, this year mostly after the Duo Normand. As per usual with our cycling jaunts (and this is a recurring theme in write-ups of our tandem tours) a lot of our energy is focussed on finding nice food and drink to consume.
I've posted a brief article (On the gain of genes and gene function) over at Wonderful Life on two recent papers that reveal something of the rate and nature of gene duplication and diversification within the species of Drosophila. This is by way of response to recent review article written by the prominent supporter of Intelligent Design creationism, Michael Behe.
The bearded rotund dude clad in red paid a visit a few days ago, leaving a selection of gifts, among them a Squeezebox Radio. This is part of a range of wi-fi audio devices from Logitech - I already have one of the original Squeezeboxes, now renamed Squeezebox Classic.[caption id="" align="alignleft" width="268" caption="Squeezebox Radio (image via Logitech website)."][/caption]Each of these devices connects to a server system that serves audio streams, either from local audio files of from the internet. In my case, I'm using a QNap NAS box as a server. The software for this, Squeezebox Server, is available as a download for a variety of platforms, including Linux, OSX and Windows, as well as a perl tarball. Squeezebox server supports multiple players, which need not be playing the same audio streams. Squeezebox Server is open source, and supports a whole array of plugins. My current set up consists of a Squeezebox Classic, the new Squeezebox Radio, and the iPad app SqueezePad which following a recent update now has the ability to use the iPad as a player. In addition, one can emulate the players on one's computer using Squeezeslave.I intend to use the Squeezebox Radio to replace an ageing radio alarm clock. Reviews suggest that it's a bit unreliable as an alarm clock when used to play internet radio feeds from the Logitech server. In my case I'll be mostly streaming BBC radio via the iPlayer plugin.The Squeezebox Radio is principally operated by the buttons and knobs on the front panel, though some of the functionality can be accessed via Squeezebox Server. A remote control is available separately along with the rechargeable battery pack (which bizarrely isn't included unless you've selected the device as part of a bundle). So, in order of size:The colour monitor shows the status of the device. It can be set to show a variety of information while playing or in standby: I've set this to show the time and date most of the time. It can be a bit bright for use as a bedside radio, but this can be addressed by adjusting the brightness and the theme in use.The large knob isn't actually the volume, but the selecter used to scroll down configuration options and through the music files. You push it to make a selection. The on/off button, actually more of a standby button is bottom right, with the volume knowb bottom left. There are several switches for 'Home', 'Back' and the like, which are used in navigating the menu system, along with conventional play, pause, ffwd etc functions.The six silver buttons (three either side of the display) are used to preset playlists and radio stations.In use, the thing was almost ridiculously easy to set up. It quickly found my wireless network. I had a brief pause while I figured out what my login details for the squeezenetwork were, but then the remaining setup was straightforward, including a download of a firmware update.Sound quality is pretty good for such a small device. Setting the alarms is easiest using Squeezebox Server, but many of the things I've tweaked have had to be done through the devices interface itself. This includes setting preset playlists, and setting the display brightness and theme.Does it work as an alarm clock? Yes, no problems on the testing so far. I have one or two worries about bandwidth when the server is doing backups, and I'll need to keep an eye on this.I'm really very pleased with the device - so far it's worked well, though of course it needs to b
