Mapping Java Thread ID to the hex id of a stacktrace

Dustin — Sun, 29 Mar 2009 00:07:48 +0000

So you generated a stacktrace and also identified the thread which is causing you so much pain but don’t know how to map one to the other? Do it like this: Find the PID of the java process: host:/service/activemq/log/main# ps -ef|grep activemq activemq 24380 20411 0 Mar25 ? 00:02:56 /usr/bin/java -Xmx512M -Dorg.apache.activemq.UseDedicatedTaskRunner=true -Dcom.sun.management.jmxremote -Dactivemq.classpath=/usr/local/activemq/conf; -Dactivemq.home=/usr/local/activemq -Dactivemq.base=/usr/local/activemq -jar /usr/local/activemq/bin/run.jar [...]

Hm, I guess we are lucky to reach the final. Turkey was clearly the better team. Thank you Philip Lahm!

Germany vs. Portugal (3:2)

YAAAAAAAAAAAAAAAAAAAAAAAAYYYYYYY! We actually made it into the half finals of EURO 2008. I really have to repent for not believing in us winning against Portugal. What a game, probably worth a final! Unbelievable…

A Day At The Park

Friday night we decided to drive over to Amsterdam and enjoy the A Day At The Park open air on saturday with Sven Väth and Dubfire. A few colleagues of my beautiful girl had asked us to join them and it sounded like a great idea – except for the weather forecast which promised rain [...]

The following small script has been copied over from madboa.com: #!/bin/sh # # usage: retrieve-cert.sh remote.host.name [port] # REMHOST=$1 REMPORT=${2:-443} echo |\ openssl s_client -connect ${REMHOST}:${REMPORT} 2>&1 |\ sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'

I went ahead and installed [...]

ASV Winterlaufserie: 3. Lauf (Half-Marathon)

Dustin — Sun, 30 Mar 2008 10:04:38 +0000

Yesterday I finished my first half-marathon in a beautiful net time of 01:58:45 (I would say that’s OK for someone that did not do that much training upfront). Of course this was only possible because I had the excellent pace-makers André and Stefan (www.gute-beine.de) helping me keeping the pace and faith (after 13km my mind [...]

Dustin — Mon, 17 Mar 2008 09:44:06 +0000

So your binary logs have grown to an ugly size eating up most of your servers disk size? The easiest way to truncate the logs in a proper way is to run the following command: reset master; Please note: This command works for MySQL >=5, for older versions use flush master;. Update: There exists a system variable that [...]

Ubuntu: Disable PC Speaker beeping (beep beep beep)

Dustin — Thu, 21 Feb 2008 08:15:33 +0000

Ever tried to get rid of the annoying PC Speaker sound (e.g. when using auto-completion in a shell)? Under Ubuntu (and probably other distributions as well) do the following to bring silence to the masses: For the running system: rmmod pcspkr Forever (aka after a reboot) edit /etc/modprobe.d/blacklist and add the following line to the bottom blacklist pcspkr
