If you want to know in which order RedHat will execute init scripts, then you can list them like this: grep '#\s*chkconfig:' /etc/init.d/* | sed 's/:#//; s/\/etc\/init.d\///;' | awk '{ printf "%2s %2s %7s %s\n", $4, $5, $3, $1 }' | sort which will produce on my system: 01 99 12345 sysstat 02 99 12345 lvm2-monitor 03 97 235 sysstat 05 95 345 kudzu 06 99 12345 cpuspeed 08 92 2345 ip6tables 08 92 2345 iptables 0 99 2345 microcode_ctl 10 90 2345 network 11 88 2345 auditd 11 89 - netplugd 12 87 2345 restorecond 12 88 2345 syslog 13 1 345 setroubleshoot 13 87 2345 irqbalance 13 87 2345 mcstrans 13 87 345 portmap 13 87 - multipathd 14 86 345 nfslock 15 85 2345 mdmonitor 15 85 - mdmpd 18 85 345 rpcidmapd 19 69 - rpcsvcgssd 19 85 345 rpcgssd 20 80 - kdump 22 85 345 messagebus 25 75 345 netfs 25 88 2345 pcscd 27 73 - ypbind 28 72 345 autofs 30 74 - nscd 35 65 - krb524 41 89 - rdisc 4 99 2345 readahead_early 50 50 - netconsole 55 25 2345 sshd 56 50 345 xinetd 58 74 - ntpd 60 20 - nfs 64 36 - mysqld 80 30 2345 sendmail 85 15 2345 gpm 85 15 - httpd 90 10 2345 xfs 90 10 - psacct 90 60 2345 crond 91 35 - smb 91 35 - winbind 95 05 2345 anacron 95 05 - saslauthd 95 5 345 atd 95 5 - conman 96 99 5 readahead_later 97 03 345 rhnsd 97 03 345 yum-updatesd 98 02 345 avahi-daemon 98 02 345 haldaemon 98 02 - avahi-dnsconfd 99 01 2345 smartd 99 95 35 firstboot Tomáš Pospíšek Read on

Copying a DVD under Linux wasn’t a problem for a long time. I always used k3b. However lately I failed to copy a DVD. k3b would say: "failed to retireve all CSS keys" or in german "es konnten nicht alle CSS Schlüssel geholt werden". k9copy would say: "libdvdread: Error cracking CSS key for /VIDEO_TS/VTS_03_1.VOB (0x0031ccb6)!!" First I thought k3b didn’t have access to libdvdcss. However it turns out that aparently some DVD drives won’t return data from some sections of a disc if the region code of the drive is not set.

OpenStruct is a nice tool to work with. However… Let’s say you do this: user = OpenStruct.new( :name => "Franca Botanica", :uid => "777" ) address = OpenStruct.new( :user => user, :country => "Paraguay" ) some_stuff = [] some_stuff << user some_stuff << address and now you want to iterate over the some_stuff collection and want to dump all those “containers” you created. But how do you find out which fields those OpenStruct instances have? Read on

When I run the statically bound Mojotron executable, as downloadable from sourceforge under Ubuntu Interpid, then it doesn’t recognize the arrow/cursor keys. I.e. changing the direction of the shots is not possible. This can be “taken care of” by changing the Mojotron configuration file: $ diff -u ~/.mojotronrc.orig ~/.mojotronrc --- .mojotronrc.orig 2009-04-13 12:43:57.000000000 +0200 +++ .mojotronrc 2009-04-13 12:44:43.000000000 +0200 @@ -8,11 +8,11 @@ section Player1 { usekey = 62 (type=integer); movement = wasd (type=string); - aiming = cursorkeys (type=string); + aiming = ijkl (type=string); } Tomáš Pospíšek Read on
