The forums at nodpi.org are an extremely useful source of information on Phorm and allied aspects of internet privacy issues.  In particular, I've recently found that their coverage of the appearance of the Phorm website which aims to smear their opposition has been fun, particularly the whole "privacy pirate" schtick.  More seriously, some of the accsations on that site have proven to be untrue.  Clearly the nodpi website continues to be a thorn in the side of Phorm - I strongly recommend that broadband customers of British Telecom have a look at the discussions there.

Supporters of Phorm sometimes post on a number of discussion forums around the web, including nodpi, leave comments on articles critical of Phorm (it must be an uphill battle, as most of the articles I see on the topic seem to be critical of Phorm), etc, as it their right.  Last night it seems that a concerted assault on the nodpi forums took place, with Phorm supporters posting articles containing pornographic material and personal attacks on members. As usual, these passed me by (as I was in the land of nod), but I think it took a lot of time for the admins to clear it all up.

It's been a while since I last blogged about peer-reviewed science.  In a recent Departmental Journal Club, I discussed a paper outlining the use of transgenic RNAi in Drosophila.  In this paper, the authors utilise the power of Drosophila transgenics to use RNAi mediated gene knockdown to identify components of an important developmental signalling pathway.

In contrast to other systems, such as mammalian cell culture systems, in which RNAi mediated knockdown of gene expression is mediated by the introduction of short double-stranded RNA molecules, in Drosophila researcher use longer double stranded RNA molecules.  There are two method of using RNAi to investigate gene function in Drosophila.

This time trial is an annual event for me - and in fact Richard (the organiser) this year emailed to remind me of it!  As has so often been the case this year, it was a pretty windy day, with all the signs indicating the race would be a flyer on the outward leg, but a real grovel back to the finish.

And so it proved.  However, to backtrack slightly.  It became immediately obvious that there were real problems with my HRM bike computer.  For a start it was registering about twice my actual speed.  This was (and remains) something of a mystery.  I've checked in case it was some kind of prank played by a clubmate - but no.  I can only assume it's the transmitter on the fork blade playing up.  And to cap the dismay, the heart rate display kept leaping up to unfeasible levels, such as 228bpm.  I was using a chest transmitter unit that was really rather old, and I suspect that the battery life was pretty much expired.

The BBC reports (DNA data plan comes under fire) that the Government's wholly inadequate response to the European Court of Human Rights ruling that retention of DNA profiles of individuals who have not been convicted of an offence is attracting considerable criticism.

In response to a number of commentators' objections to the Government's plans to continue to retain these data for up to 12 years,

I have just upgraded this site's blogging software from MyBlog version 2 to version 3 (from Azrul), everything seems to be working OK, but let me know if there are any issues.  I have noticed cosmetic changes, most notably the raindrop panel on the front page, but there seem to be significant improvements in the system's functionality (this posting is mostly to see how they work!). 

This week's time trial event was the third counting event in the NBRC club time trial league, and the first of the 2009 interclub events with the A5 Rangers Cycling Club.  It was held on the F5d/10 course, based on the Stoke Hammond bypass.   At the club room, there was quite a bit of discussion of the tragic events of the previous Sunday's tragedy, and certainly it was with some trepidation that I lined up to start (particularly with the cavalcade of fast and noisy motorbikes that passed just after I started). I had chosen to ride the Cougar with a pair of Hed trispokes.

A minute in front of me was ace fast man Tim Carter, so I knew from the off that I'd not see my minute man!  The wind has been strengthening all day, and must have matched that forecast (see symbols above) - it was pretty hard at the start, with a climb into a strong headwind, sufficient to make the bike quite a handful to control  with the front trispoke seemingly determined to alternately trying to dump me into the verge then into the traffic. An added irritation was that my HRM/computer was registering completely aberrant speed details.

 xkcd on Windows 7.  Actually, I'm looking forward to seeing Windows 7 - my experiences with Vista were rather unsatisfactory.  Mind you, I'm a confirmed Ubuntu user these days...

Over at the Team Grumpy website, I've posted an article on the UCI bike regulations and how they relate to the design of time trial bikes.  At the weekend, I'll measure up my bikes to see how they fare - I expect both to need adjusting to fit the criteria, but the dreadful 1:3 rule probably rules out the handlebars on both bikes, also the front fork and seat pin on the Cougar.  Of course the main reason for this is the suggestion mooted a month or so ago on the timetrialling forum that the Duo Normand would be enforcing UCI regulation in all categories (not just the elite categories).  Whether these rumours have foundation, I don't yet know.  I suppose that formally time trials in Scotland, which are run by the BC-affiliated (and therefore UCI-affiliated) Scottish Cycling Union, ought to enforce these rules, as should the BC-CTT jointly run British Time Trial Championship.

Cycling shoes have a number of distinctive features - they generally have very stiff soles (with screw fixings to take shoe plates that clip to pedals), and often have exotic fastening systems (shoe laces are so last millennium!).  Common fastening systems include velcro straps and a variety of ratcheting designs.  Personally, I dislike velcro straps, and prefer the ratchet systems, as these are more amenable to adjustment while riding.

A couple of years ago, I bought a pair of Specialized S-Works shoes (see left), which featured a ratchet system that tightens up a criss-crossing string across the upper, and which fastens the shoe very effectively.  Unfortunately, the other day, the string snapped, leaving me to compete with a shoe held together with gaffer tape.  I disassembled the ratchet this morning and was struck by how the string resembled plaited dental floss.  I repaired the shoe with three lengths of dental floss, and it seems to have worked.  At least, it's stood up to full tightening with no sign so far of giving way!

12-15 mph NW wind - rather blustery.
