Cracked Crank

Last Sunday I was doing some interval training on my turbo trainer when I noticed a nasty mechanical clicking sound from somewhere around my bottom bracket. It sounded just like a cracked bearing, so I borrowed a crank extractor, took the cranks off, only to find that my BB bearings were absolutely smooth, no sign of a problem at all. Mystified, I put the cranks back on, and while I was doing that, noticed that the left crank was cracked from centre hole to the outside of the spider, all the way through. I’m very glad I wasn’t riding when it finally went! XT stuff isn’t meant to do this!

It turns out that it’s more or less the same price to have a new combined BB and chainset rather than just replacing the old taper-fit chainset, and it should be lighter, stiffer and stronger into the bargain. So Chain Reaction delivered me a nice Deore LX Hollowtech II chainset, and Brockley Cycle Team fitted it for me today, along with some good advice.

(Added a picture of it 22/9/2008).

ClamAV broken version check

If you’ve just built and installed the new version 0.94 of ClamAV (because it reminded you that your current version was out of date), and you’re using the experimental features, it exposes a rather dumb bug that results in these messages in your freshclam log:

@4000000048be74fd0687f57c Software version from DNS: 0.94
@4000000048be74fd0688245c WARNING: Your ClamAV installation is OUTDATED!
@4000000048be74fd06883014 WARNING: Local version: 0.94-exp Recommended version: 0.94

Apparently ClamAV’s version comparison is not terribly clever, and the ‘new feature’ of marking experimental versions with ‘-exp’ has tripped it up. I’m sure there are multiple workarounds, but I changed this in shared/misc.c:

#ifdef CL_EXPERIMENTAL
/*#define EXP_VER “-exp”*/
#define EXP_VER
#else
#define EXP_VER
#endif

as the EXP_VER string is what gets appended to the version number (apparently only for display purposes, but it does the trick). I then rebuilt it and now my log says:

@4000000048be848926da098c Software version from DNS: 0.94

Yay – no error!

Sailing

Zoë and I sailed from Gibraltar to Almerimar with my Mum this weekend. I use “sailed” a little loosely as there was essentially no wind, so we motored nearly all the way. Zoë had a fantastic time. The weather was lovely, and with so little wind, it was really easy to stop for a swim every so often (like when the water temperature sensor said 27°!). The highlight for me was sitting down for dinner in the setting sun and being joined by 40 or so dolphins. Highly recommended!

Safari 4 preview

I just grabbed the new update to the Safari 4 preview, and I have to say it’s very zippy indeed. I ran SunSpider benchmarks on it and FireFox 3.0.1 on my Mac Pro. Safari 4 is on average 75% faster, but has many results that are in the 200 – 500% range.

This is only measuring javascript performance of course, but that, plus whatever other changes are in S4, translates to incredible speed in daily use. I use the SafariStand extension to remember my open tabs, and I can reopen about 40 tabs in 8 windows in about 3 seconds, including all their content! FF 3 was a huge improvement over 2, but Safari 4 is a different league. This is only a preview, so it will probably get faster still by release.

The integration of the JS debugger is very elegant (Drosera has been rolled in), but I’m still looking forward to the appearance of FireBug for Safari, which someone is doing as a Google SoC project (S4 adds some FireBug hooks too).

All the new CSS funkiness from recent webkit nightlies is there too, and I suspect many an iPhone and widget developer is drooling over them…
