They’re doing it again

As I wrote about in Rants and Revelations » Dear Boss, my boss has a stick up his ass about my DocumentCache, and blames it for any problems with the cinlib long before any evidence comes in, and continues to do so time after time years after the last time it was actually a problem.

So yesterday we were discussing a problem and Tony asked for something new to be put in the DocumentCache, and the head of QA starts saying “I don’t want you guys messing with DocumentCache so close to the release date because it always seems to be causing problems”. AAARRGGGGHHHH!!!! I patiently explained that, no, the DocumentCache hasn’t had a bug against it in three years, it’s just a matter of perception because every time there is a bug anywhere near that part of the code “somebody” (I didn’t say Dave’s name) thinks it’s a DocumentCache bug even though it never turns out to be the case that it is.

The next time I write something that caches something, I’m not going to use the word “Cache” in its name. I’m going to call it the XMLPuppyAndKittenPlayground or something.

Wiki currently shut down

My “DAFIF Replacement” Wiki is currently shut down because of a bug that was causing my computer to hit load averages up over 10 every time Google indexed it. My log files were full of lines like:

[Thu May 31 21:09:21 2007] [error] [client 66.249.72.194] [Thu May 31 21:09:21 2007] view: Use of uninitialized value in string eq at /var/www/twiki/lib/TWiki/Plugins/TablePlugin/Core.pm line 457.

I hope to have time to upgrade to a newer version of TWiki Wiki one of these days and then I’ll re-open it. Or possibly I’ll just let it die since it wasn’t getting any use anyway.

Side effect, or my imagination?

For two or three weeks I’ve been trying a different pain medication, a NSAID called “relafen”. I’m not sure if I’m imagining it, but it seemed to me that last weekend when I went flying I was more susceptable to motion sickness than I have been in the past. And yesterday while I was concentrating on something on my screen (ok, it was the live updates from the Giro D’Italia, not work), I suddenly felt like I was going to lose my balance and fall over, which is kind of odd to happen while you’re sitting still. I also seemed to have to remind myself to breathe when I was concentrating – but hey, it was a exciting mountain stage, what can I say? The “hey, I’m losing my balance” feeling just happened again today, even though the Giro stage I was watching work I was doing was pretty unexciting.

One web site listed vertigo as a very rare side effect of relafen. But why now after 3 weeks, and not back when I started?

Oh well, I’m seeing my doctor tomorrow. Maybe he’s got a different medication to try.

Note to self

If you want to find a picture you saw yesterday, and now the picture has been removed from the web site that you saw it on for copyright reasons, *and* you haven’t exited Firefox in many weeks, *and* you have had a web page open on one page that is constantly showing you different parts of the world in Google Maps in hybrid mode, DO NOT try to find the picture by going to your .mozilla/firefox/*/Cache directory and typing “kuickshow *”.

After my screen filled with several hundred images, mostly Google Map tiles, it started getting really slow. My CPU was pegged, I was swapping heavily, and still images were appearing. The mouse was moving, but nothing was responding to clicks or keyboard presses. I went to another machine, ssh’ed in and did a “killall kuickshow”, but the load average was still over 8. I waited a while for it to drop down to under 1.0, but my display was still unresponsive. Eventually I gave up waiting for it to recover and rebooted.

Of course, my Cache directory is now nearly empty and I’ll never find that picture again.
