drives me absolutely up the wall!!!

Basically, all I do all day is review slide decks.  Day after day after day.  (The paperclip icon in Thunderbird makes my heart race.)  Anyway, today I'm walking through yet another slide deck when I get to a slide that starts out like this:

Apache Specific Tuning
 ListenBacklog 16384
 ServerLimit 8192
 MaxClients 8192
 MaxRequestsPerChild 0
 StartServers 128
 MinSpareServers 20
 MaxSpareServers 128

There's no further information!  That's the end!  Really!

/dev/tcp is ROTFL thinking about that ListenBacklog directive.  The swapper is looking for some extra volumes.  fork() and kill() and exit() are trying to get a room at the beach for the weekend.

It started to feel like I had held a match in my hand way too long as I started typing a furious response (which I had to delete).  I tried a slightly more tactful approach and had to delete that too.  After walking around the house five or ten times, I came back in and responded with a suggestion that I could cover that material properly at the Web Stack Deep Dive session at CommunityOne West in San Francisco next Wednesday.  He agreed.  Wish me luck!

Earlier today while I was trying to poke holes in the Solaris and Red Hat Enterprise Linux builds of the upcoming GlassFish Web Stack 1.5 release and (hopefully) figuring out how to solve a mod_perl/mod_security2 clash, my wife had lunch with friends and brought back a newly released album from an area jazz band that includes our friend Thomas Taylor.

The album is Stickadiboom by the Steve Haines Quintet + Jimmy Cobb (yes, that Jimmy Cobb). This is quite an impressive work. Steve is a string bass player, and the composer of most of the songs on the album. He has some solos that I am enjoying a great deal; some stretches remind me of the work by Eddie Gomez on Chick Corea's Three Quartets album (alas, this is perhaps because I haven't heard that much memorable, melodic bass).

All these guys are in top form, and everything fits together perfectly.  The band plays really tight on these songs; I expect that this is the nature of the compositions plus a great deal of sweat.  (The songs themselves are quite memorable; I'm sure that other groups will be playing some of these in the future.)  We saw Steve and Thomas with a different group of musicians recently, including a few walk ons; it came together after a fashion, and everyone had fun.  But with this album we get to hear them in a totally different, serious setting.  These are performances to be proud of.

If you like jazz, listen to the samples on the web!
