Team Grumpy back on the road

I've finally shaken off the recurrent cold that's been a bit of a burden since I returned from the USA in the first week of October.  This was convenient since my Team Grumpy team mate was visiting and we'd planned a bike ride.  This is actually rather a rare occasion for us.Of course all my assertions that we should 'take it easy' and 'don't forget I've been off the bike for four weeks' had zilch effect as we found ourselves zipping along on a beautifully clear and sunny morning (though it was rather cold at the start), particularly after we encountered an old club mate on the way, with the consequences that generally follow.  We covered around 50 miles in about 3h riding time - the furthest I've cycled since our trip to France in September, and the first 'proper' bike ride in the last month.  We did stop at a cafe in Winslow, which was just as well, since by the last 10 miles, my legs were suffering.It was notable how 'mobile' my heart rate was: while mostly it was in upper level 1 or lower level 2, it didn't take much for it to leap up to levels that I normally see during short time trials.  So recovery is still some way off, I guess.  Added to which, as I write this the following morning, I do seem a bit achy - particularly my neck.Oh, and I did collect a slow puncture a mile or two from getting home.

Government U-turn over data tracking

It would seem as though the UK government has quietly performed an about turn and revived the Intercept Modernisation Plan ('Surveillance state' fear as government revives tracking plan | UK news | The Guardian).  As The Guardian reports:

A £2bn plan to allow the police and security services to track the email, text, internet and mobile phone details of everyone in Britain is to be revived, the Home Office has confirmed.The coalition agreement promised to scrap the "surveillance state" plan by pledging to "end the storage of internet and email records without good reason". Both Conservatives and Liberal Democrats voiced criticism in opposition.But the project, known as the interception modernisation programme, has been quietly revived - a decision buried in the back pages of the strategic defence and security review published this week. Senior Home Office officials have confirmed that legislation is being prepared.
You might have thought that in the current climate of swingeing cuts in public expenditure this might have remained axed.  But no, it's back.The plan doesn't yet include retention of the content of messages (but as ever, beware of 'function creep').

App stores on PCs...Macs...Linux

Following the announcement of the upcoming OSX app store, it's reported that Microsoft is (supposedly) working on a Windows app store, too.Hang on - isn't this what we do with Ubuntu?One of the things that delayed my buy-in to the iPad was the whole walled-garden of the thing - without jailbreaking (with it's attendant consequences) I'm committed to only obtaining and running software available through the App Store.  Now, I eventually concluded that the iPad, like the iPod Touch, is actually a consumer device rather than a computer per se, and I can see why Apple have gone down that route. And I've found the iPad to be an impressive device fr many of my day to day work (and entertainment) activities.Regarding the proposal of an "App Store" for Mac OSX, I was rather relaxed.  After all Linux distros have really had this kind of facility for years - in the form of the repository system used by whatever packaging system used.  In Ubuntu I either access this via the command line or via Synaptic.  There is of course the "Ubuntu Software Centre", which seems to me moving from just a listing of free software to also offering commercial software.In that sense, moving to an App Store model for distributing software for computers isn't particularly innovative, unless it becomes the only way to install software.  It appears that the OSX app store is to be incorporated in next year's OSX 10.7 and added to the current OSX 10.6 pretty soon (Mac OS X 10.7 "Lion" - Sneak Peek).I'm a little uneasy about this move: I don't want to work in a completely closed software ecosystem, and I'm not getting a sense of whether this will be the exclusive mode of software installation. I guess this will be resolved quite soon, as it's coming to OS X 10.6 in the coming months.Update:  Ars Technica's review of yesterday's Apple media shindig (Mac OS X 10.7 Lion: "Mac OS X meets the iPad") quotes Steve Jobs as saying that the Mac App Store won't be the only place to get applications—just "the best place." So that's OK -  for now...

Civil research budget cuts to be 10% (BBC)

Sitting awake after another nocturnal coughing fit (will this darned cold never shift?) in the early hours of the day in which the Government's Spending Review details will be announced, I notice that the BBC is reporting that the civil science research budget is to be cut by "only" 10% over four years (Science cuts 'less than feared').   Still bad, but  I guess we will feel a sense of relief after the  Government spin of recent weeks.  As the BBC report says, the Royal Society submission to the Government earlier this year said:

A 10% cut would "fundamentally damage the quality, productivity and capability of the UK's research base".
I guess the quality of the Government's spin doctors is revealed by the sense of relief that the cuts will be 'only' 10%.Still of concern is where the cuts will fall.  The BBC's report says that the Medical Research Council may lose least as it's viewed to fund research that fits "national priorities", while those funded by the Science and Technology Facilities Council may be more worried.  No mention of the BBSRC in the report.Still, while the USA and other competitor nations raise their research budgets (in terms of % GDP), we are taking the opposite direction.See also Spin Spin Spin.

Maverick Meerkats, Macs and me

I am wondering if I am turning into a Mac Fanboi...I recently bought my first Apple computer (I don't really include iPods or iPads as computers), in the form of a 13" MacBook Pro.  This purchase came shortly before the release of Ubuntu GNU/Linux 10.10 (Maverick Meerkat), of which more later.  Over the years, I've had computers running Windows 3.1, 95, 2000, Me, XP, Vista (possibly my least favourite) and most recently Windows 7.  Since about 2000, I have been using Linux, starting with an ancient version of Red Hat, then Mandriva, and for some years now, Ubuntu.  In fact I've rarely used Windows except for specific applications in several years now.  The Windows 7 desktop PC was bought and promptly set up to dual boot; the Vista notebook (a Sony Vaio) was so woefully underpowered for Vista that it was first used as dual boot with Ubuntu, then the Vista partition scrubbed.The trigger for this purchase was my experience giving a presentation at a conference recently.  I had an 8 minute (!) presentation to give: this was straightforward, except I wanted to include a brief video.  My Linux notebook running OpenOffice.org flat refused to project the video, using Powerpoint 2003 via Crossover Office, I couldn't even embed the video.  Switching to my Windows 7 desktop PC and its trial version of Office 2007, I was delighted to be able to embed the video and get it to function.Of course I needed to check the presentation at the conference.  Powerpoint 2003 on an XP machine wouldn't run it.  Powerpoint 2007 on the projection system wouldn't run it.  Powerpoint 2008 on the Mac presentation system wouldn't run it.  This was less than 24h before I was to deliver the presentation.  I ended up processing the video on the Linux notebook and regenerating the presentation on Mac Powerpoint 2008.  Nerves of steel I do not have, so this was undesirable pressure.I've had the MacBook Pro for a little over a fortnight now: other than iWork (which I obtained at a significant reduction), all the software I've installed has been open source: Firefox, Chrome, GIMP, Inkscape, Mendeley, OpenOffice.org, and FileZilla to name a few, thereby recapitulating quite neatly my experiences with Linux.  The hardware and build quality of the MacBook is second to none (it's annoying to have to buy an adapter to make a presentation, but the power brick is so small as to be genuinely portable).In the meantime, I've updated a venerable Sony notebook and a Dell desktop to Ubuntu GNU/Linux 10.10, with no issues.  No astonishingly obvious changes visible so far.  Gnome-Do doesn't seem to play with Docky; the Ubuntu Software Centre is a bit easier to use (but I don't use that very often); Trash is renamed "Rubbish Bin" in dialogues, but not on the desktop.  I dare say a bunch of other stuff will become evident in the coming weeks.

2010 season review

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 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.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.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 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 it didn’t count).  We rode no further 2-up events until the Duo Normand in late September.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.  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 th 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 on the course!  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.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 and climbed onto the podium to receive a glass trophy, a bunch of flowers and the all-important podium girl kiss.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!

Alberto Contador and the plasticiser

I'd been pondering the discovery of plasticiser in Alberto Contador's doping control sample, when I came across an excellent overview at the VeloNews site (The Explainer: Plastics - VeloNews).  It's well worth reading to put the latest accusation in perspective.It would not seem to be an open and shut case.And furthermore, the issue of the sensitivity of testing lab procedures really needs to be addressed.  If WADA-accreditation requires a particular detection limit for clenbuterol, than that needs to be the limit for consideration as a positive test result.  Otherwise dope-testing becomes a lottery where some riders escape sanction because their samples were sent to a laboratory with less sensitive equipment.

More gossip about Contador

Velonews reports more on Contador's "doping violation" (Former French doping chief says there have been rumors about Contador since July, quoting Pierre Bordry (former head of the French anti-doping agency AFLD) as saying rumours had been flying since July.  Interestingly, he says of the small concentration detected (40 times less than a lab is required to be able to detetc - not 400 times, as widely reported) that

“It doesn’t matter how small the quantity is. Clenbuterol is on the banned list,” Bordry told RTL radio. “Contador can do what he wants to make a defense, if it had entered his system one way or another, but he cannot avoid that it is a banned substance.”
That's all fine and dandy, but raises the possibility that an athlete's guilt or innocence might depend on which testing lab his/her samples go to and how far below the reuired sensitivity thay are able to take the detection.Hardly seems fair to me.In the meantime, accusations have been flying that Contador had taken an autologous blood transfusion on the rest day: Contador has flatly rejected those accusations (Alberto Contador denies receiving blood transfusions).

EU to sue UK over Phorm phiasco

It's been a while since I noted any news about Phorm, the outfit that hawked a system for illicit DPI snooping in internet traffic.  The Register today reports that the EU is to sue the UK over its failure to take action (EU sues UK.gov over Phorm trials).Not before time.

Is Alberto Contador really positive for Clenbuterol?

[caption id="" align="alignleft" width="240" caption="Image via Wikipedia"][/caption]
William Fotheringham reports in The Guardian today that Alberto Contador has been provisionally suspended after positive test taken during the second rest day of the 2010 Tour de France (Alberto Contador provisionally suspended after positive test).Apparently traces of the banned drug Clenbuterol were found in a urine sample: Clenbuterol is a bronchodilator used by asthmatics (clinically) and illicitly by athletes to improve breathing and enhance weight loss (presumably the latter's not an issue in a Grand Tour).  So Contador has been 'provisionally suspended', whatever that means.  Interestingly Fotheringham goes on to write:
Contador was notified of the finding on 24 August, his spokesman said yesterday. A statement from cycling's governing body, the International Cycling Union, issued this morning said that the concentration of clenbuterol found in Contador's urine was 50 picograms*, 400 times less than the threshold required by a World Anti-Doping Agency accredited laboratory, and that investigations were in progress.[*50 picograms = 0.05 nanograms = 0.00005 micrograms = 0.00000005 milligrams = 0.00000000005 grams]
Leaving aside the observation that 50pg is not actually a concentration but an amount, why is there a case to answer here if the amount detected is 400 fold less than required by a WADA accredited laboratory (presumably to call a positive).  What, one wonders, is the UCI's doping limit for clenbuteral?  And furthermore, presumably Contador had tests on other days of the Tour - if he was doping, wouldn't clenbuterol have shown up in those?  A WADA representative is quoted as saying
The issue is the lab has detected this. They have the responsibility for pursuing. There is no such thing as a limit where you don't have to prosecute cases. This is not a substance that has a threshold.
Which kind of contradicts the earlier statement in the article. This really comes across as a mysterious case.  I await a UCI statement about the matter.  From my science-based viewpoint, there have to be limits below which sanction will not be taken: as analytical methods improve in sensitivity, one might expect to see all sorts of false positives, ranging from contamination to just confused results.What should happen if an athlete recorded 0.5pg?  Or less - maybe 0.5 femtograms (which is 0.0000000000000005 grams - I think - all those zeros get confusing! 50 pg is usually written as 50 x 10e-12,  0.5 fg would be 0.5 x 10e-15)I guess this one's going to run for a bit.I read an article in the journal Science around the time of the Landis positive, which made for interesting reading concerning the possibility of a false positive occurring during multiple tests of an individual during a three week event: this concerned the EPO test, which by it's nature has an arbitrary cut-off for a positive to be called.Other relevant posts in this blog

2010 cycling trip to Normandy

Once again we visited Normandy for the Duo Normand time trial, and to do a little cycling on the tandem.  This time we were there for a little over a week, based in a cottage between Cerisy-la-Salle and Notre Dame de Cenilly just south of the race's base in Marigny.An overview of the cycling, with route maps and photo galleries can be found via the Cycle Tours option in the CYCLING menu on the left side of the website, or by following this link: 2010 Normandy.  Bear in mind this is something of a work in progress!

Duo Normand 2010

We woke at 7am, had a quick breakfast and packed the car.  Then we drove over to Marigny in convoy with Gerry - this didn't take long.  In Marigny, we parked in our usual spot, not far from the start area.  We wandered down to see the first unlicenced rider start, at 8.35.  We were pretty glad we were in the Corpo category, as with clear skies and no wind, it was really very cold.

Of oysters, oyster stout and kangaroo - and giant puffballs

[caption id="" align="alignleft" width="210" caption="Image via Wikipedia"][/caption]
After this morning's rather lacklustre time trial (see previous post), it was off to Woburn for the annual Oyster Festival, in which the town that's possibly furthest from the sea transforms itself into Woburn-by-the-sea for a weekend.  The centre of the town is filled with stalls offering oysters (and other sea food), beers (including the headline Oyster Stout), and a wide variety of mostly meat-focussed foods.First up for consumption was half a dozen rather large oysters, eaten freshly opened with a squeeze of lemon juice and accompanied by a pint of oyster stout.  This was from Marston's, from who's website the image to the right is linked.  It's a wonderful stout that makes an excellent partner for the oysters (though to doesn't itself contain oysters!).After I'd washed down the oysters, I still felt a little peckish, which is where the kangaroo comes in - it was off to the kangaroo, ostrich and crocodile stall.  Unfortunately the grilled crocodile had proven popular and there was none left (otherwise that's what I'd have had) - we had a roll filled with grilled kangaroo  (me) and ostrich (Carol).  Frankly, the kangaroo was a little undistinguished - I thought it could have been any grilled meat.[caption id="" align="alignleft" width="200" caption="Giant puffball"][/caption]While walking over to Woburn, I happened to spot a few giant puffballs (Langermannia gigantea) in the verge, and nabbed a couple of relatively small ones.
Back home, one of these was the base for a rather nice pasta sauce, along with some smoked bacon.  Yum.  The other one went off with our friends...
