Original published 1988 summit notes from the last “Economic Summit” that closed Toronto. Wonder if anything sounds familiar…
I’ll transcribe it shortly into text; the Apple OCR can’t parse the 23 year old typesetting on this pdf scan that York put up a couple of years ago. Page 4 is the text if you feel like downloading the pdf. Oddly enough, Tony and Carol Lee are still Republican writers.

Not liking the double tweet thing…
so I have disabled posting to PBJ laconica through the WP laconica plug in; I had it set to post to pbj, which then reposted to twitter…
Still like the twitter feed on the blog front page, though not as much as the “where am i” google latitude thingy…

Not much more to say. It defaults to regex. Change it to wildcard. Most simple rules can be done with wildcard. The regex engine is, shall we say, greedy? Same issue with the built in ASP.NET library. Avoid heavy use of regular expressions on IIS web apps, they really slow things down on high traffic sites.

Phoenix: Wolfgang Amadeus and Jonsi, beautiful 180 gram vinyl. Phoenix with hi-res 320 mp3 rips. Cannot ever decline great vinyl.

Noticed today that the webapp struggles as it gets to within 50 meg of the virtual memory limit threshold for recycling the app pool. This happens no matter what the threshold is set to. 2 gig, 1.7, 1.6. Same thing. We speculate it is going into GC (garbage collection) mode, and CPU gets high. It hits the limit, recycles, and is happy again for an hour. Since it was recycling around once an hour, I thought I’d remove the memory limit, and just recycle once an hour. Bad Thing. With no memory limit, URL Rewrite 2.0 kills the CPU. We were pinned at 100% in 45 minutes.

Conclusion: hard won tuning settings are always worth questioning, but if they run reliably and keep you up, it’s unlikely that disabling a setting will do anything but expose other problems.

Probably worth looking at the registry settings for relations between memory and CPU for rewrite.dll but the solution is likely to be less use of the dll overall, combined with memory threshold recycling.
