[OT] Ragel and FSM tutorials
This is off-topic. I''m hoping someone on this list can point me towards more general information on finite state machines, their definition, how to build them, determining when to apply them, etc. I read Zed''s blog entry from way back when covering Ragel [1] but he hasn''t followed it up and there aren''t many pointers to external information.

GVN pass: does global value numbering remove duplicate computations in loops?
Hello, I was hoping to get some clarification on the aim of the GVN pass. I have been reading a bit about global value numbering, and from what I understand, there are polynomial time algorithms for removing duplicate computations from loops[1]. I have an example program[2] which computes the sum of an array twice, in two separate accumulators. Here, sum0 and sum1 are both sums of the array A.

The answer is blowing in the WINS
...e. and . Unix hosts are so much quicker to respond to my input than any MS product . There are more cheap, easy to use, readily available tools for Unix than MS products (Perl being the only exception). I'd really like to hear your answers to these questions. Thank you, Yours sincerely, S Hopcroft

Aggregating logs from numerous FreeBSD machines
Hi folks, My stack of trusty FreeBSD servers always seems to be growing, and it's getting to the point where the daily and security output mail is too much to make good use of. I'm looking for suggestions for log monitoring and aggregation tools, especially from a monitoring-for-security perspective. If I had to imagine an ideal system, it would be a central server that securely

Dear Ladies and Gentlemen, I am writing to ask your help with a problem whereby 3 NT4.0 + Sservice Pack 3 servers frequently log (in their event lists) that the browsing service cannot get the list of domain resources (the reply to NetServerEnum2) from the master browser (when the boxes are functioning as backup browsers). The situation is :- . NT machines browsing on both NetBUEI and NetBT
