I don't know how good the book is, but the price is right... Borders, at Bell rd and about 75th ave(?) has "Linux Core Kernel Commentary, 2nd edition" on their bargain table for $6.99. There were at least 6 left last night. Original price was $49.99; says it covers kernel 2.4.1. I also picked up "PERL Black Book, 2nd edition" for $5.99, but I may have got the last one. Original price $59.99. Comes with a CD, claims to have versions of all scripts for both unix and 'doze. IF2 was a blast; thanks much for the spiffy hat :-) Steve
