• Sleeps with Butterflies

    Butterfly flaps have interesting consequences. Apparently Edward Lorenz came up with the term butterfly effect; later he wrote a marvelous paper presented at the 1972 AAAS (speech below, and taken from another site which had the text), which explains the effect… in a way that may or may not align with how you view it.…

  • waxing nostalgic

    Got an HP server to play with, a Proliant ML 150 G6 (what’s the deal with HP’s wacko URLs?); not too expensive, and is big with really loud fans. When setting up IPMI the man advises you to “use Telnet to log in to the remote management CLP” – I haven’t used telnet in sometime,…

  • reading wtmp

    Have a wtmp file you need read? A nice perl one liner to do so: perl -we ‘@type=("Empty","Run Lvl","Boot","New Time","Old Time","Init","Login","Normal","Term","Account");$recs = ""; while (<>) {$recs .= $_};foreach (split(/(.{384})/s,$recs)) {next if length($_) == 0;my ($type,$pid,$line,$inittab,$user,$host,$t1,$t2,$t3,$t4,$t5) = $_ =~/(.{4})(.{4})(.{32})(.{4})(.{32})(.{256})(.{4})(.{4})(.{4})(.{4})(.{4})/s;if (defined $line && $line =~ /\w/) {$line =~ s/\x00+//g;$host =~ s/\x00+//g;$user =~ s/\x00+//g;printf("%s %-8s %-12s %10s %-45s\n",scalar(gmtime(unpack("I4",$t3))),$type[unpack("I4",$type)],$user,$line,$host)}}print"\n"’…

  • The Sleep of Reason Produces Monsters

    A monumental work… what a great line as well.  From the immortal Goya. Always stay vigilant….   (Image from the truly marvelous Met Museum of Art web pages, they have wonderful hi-def scans of so much… thanks!!!  What a tremendous way to bring art to the people – this bit isn’t even being physically shown…

  • cats who stare down goats

    I went to the 2011 USENIX security conference… admittedly not expecting much, but wietse was going to be there, and I must say a really, really fine show.  Yes, this is ancient history now… but so am I! Most of us spend a fair bit of time encased in two tons of steel, glass, rubber…
