Nifty NiX

I was asked if I can create a DVD/CD installer optimized for a targeted application [some LAMP and Java stuff (yes Java!)]. Being the impulsive, yes I can nut case, I readily accepted the challenge. I only realized (after creating RPMs and applying patches) that I am basically spinning my own Linux Distro! I'm aware of Fedora re-spins and other packaging what-nots, but it is only now that I'm actually getting my hands dirty.

Getting intimate with clean RPMs, that is, creating RPMs out of sources with third party patches. Oh, and that pesky beast called Java! Then again, the peskier, the more I'm challenged :). More RTFM sessions and more coffee to drink. Hoping that by April, I'm already one of those thousands who have successfully delved with distro-making.


And for the performance monitoring of systems, I came across with SystemTap. I'm still getting the hang of it. I'm also dubbing with writing some Nagios plug-ins (not really plug-ins but bash scripts on top of check_generic). People doesn't like me when I'm horny, err, busy :)


As promised, I found the link to the Zoom B2.1u cheat sheet, the pdf is located here.

Java And Other Cup of Updates

I was able to resolve the issues regarding getting some information about JVM. I had to set the $JAVA_HOME first, then execute the the simple query. Why am I getting these information? I'm doing a simple installation auditing and dumping it to a text file that can be parsed by PHP. Part of this is also getting the server's date of installation. Utilized the simple line below to get the '/' date of creation:

dumpe2fs -h `df -h | awk '{print $1}' | sed -n '2p'` | grep Filesystem\ created | sed -n '2q;1p' | awk '{print $3,$4,$5,$6,$7}'

On a separate note, I gave my wife the information about wget. She have a list of files from different http locations and she needed to downloaded them at once. Using '-i' option of wget did the trick:

wget -i list-of-files.txt


I've been experimenting with my ZOOM B2.1u bass pedal and loving it more. I found some information on easily editing the patches. I have the 'cheat sheet' but forgot to bookmark the site. I'll be posting the site as soon as I googled it again :)

Holiday Rants And Updates

Apple forced us to upgrade from Jaguar to Tiger! Why? Because the latest ipod doesn't work on Jaguar! The music player function on Nokia 6288 sucks! Why? No easy way to shift to another directory or album! Java sucks big time! When running this code snippet remotely, it wont pipe to file!

ssh remote hostname "/bin/sh /opt/tomcat/bin/ | /bin/grep JVM\ Version > version.txt"

And the PLDT WeRoam service in my area (San Pascual, Batangas) is excruciatingly slow (gprs only)!

There you are, what a post to start the New Year.
