Chris DiBona Speech

Back in Business

Now that I’ve survived my first wave of midterms, I plan on devoting more time to my extracurricular activities.
I’ve noticed that my daily del.icio.us script for Wordpress is broken, so I’ll be updating it to work again, and I’ll be finally addressing the nagging issue of time sync in that script. I also just finished [...]

Chris DiBona Speech

The UC Berkeley Linux Users Group will be hosting a speech by Chris DiBona, Open Source Program Manager for Google and a former editor of Slashdot, on October 17 from 6-8 PM at 306 Soda. As with all CalLUG events, the speech is open to the public and there will be no cost to attend.

I’m Still Alive!

I think the time gap between this post and the last post is the longest such gap this blog has ever seen.
Many things have occurred since the last post, and most of them have been keeping me very busy. Here’s some of the important stuff:
I moved back into the dorms. This will be the first [...]

Backup A Directory With Email

I wasn’t able to sleep, so I wrote this Perl script to backup a directory and mail yourself a copy. Change the variables in CAPS to suit your needs. It’s best to run this script as a cronjob.

Server Tweaking

I’ve just finished some intensive tweaking of the Cold Ray Hosting servers. I was able to reduce the memory used by Apache, our web daemon, and MySQL, our database daemon. By reducing the memory used by each daemon, I was able to release memory to other active processes.
The immediate benefit of my tweaks is a [...]

Our system has been up for a few months, and a user-friendly control panel is now undergoing testing. This weekend, I’ve added one more component to our web hosting offerings: self-service support in [...]

New PGP Key

I’ve created a new PGP key to replace my currently expired key, and I’ve attached the public key block to this message:

Linux kernel 2.6.9 and bind 9.2.4

After upgrading my Linode to Linux kernel 2.6.9 for the file-system access control lists, my bind 9.2.4 DNS server has become very unstable. The daemon will run perfectly for a few hours, but will suddenly begin consuming all the CPU. The strange thing is that the process’s memory usage remains stable and none of [...]

So What Else Do I Do?

During the weekends, when I have some free time, I’ve been (besides studying and sleeping):
Developing my ISP - pluto.betanegative.com went active last week (since renamed to mars.coldray.com). We’re currently hosted at ThePlanet with a modest amount of disk space and plenty of transfer. Since I’ve been busy with classes, I’ve only been able to configure [...]
