The I.T. Nerve Center

I've had this a couple of times now in the last few weeks. I wanted to try out the Linux KVM virtualization hypervisor that comes with Fedora 11 since VMware Server 2 is giving my fits on F11 x86_64 so I installed qemu and all the supporting packages via yum.

I realized that I can't do some things with KVM that I can with VMware Server so I'm putting up with the signal 6 crashes every week or so and went back to VMware Server 2.0.1 for Linux. In order to get that running I had to apply some patches to get the kernel modules compiled but that's been done for a while.

First some background about web applications firewalls for the uninitiated. If you already know what a web app firewall is then you can skip down to the bottom of the post for some mod_security rules that will help you with Drupal Views, the GMap module admin pages, and Google Webmaster Tools.

Sorry everyone. We had to do some long term maintenance on our server. We're back now though.

Keep an eye out for more great stuff.

UPDATE: Due to a system crash and my poor backups, I no longer have the code for this post :( I'll try to reproduce it if I have time, but that's harder and harder to come by

OK, so I have the squid shaga engine code logging most everything to a MySQL table.

In order to successfully compile squid with this patch you will need liburi. You can download the pristine source for liburi here:

Twitter is all the rage these days and I've been using one of the more popular desktop Twitter applications - TweetDeck http://www.tweetdeck.com. TweetDeck runs on top of Adobe AIR - http://www.adobe.com/products/air/.

My day-to-day OS on my workstation is Linux (Fedora 10 to be exact). I installed Adobe AIR and TweetDeck with no issues on the initial installation.

A buddy of mine at work showed me this nifty registry addition for Windows that sped up my network connections significantly.

There are a lot of postings out on the Net about performance tuning VMware products to run more efficiently. I'd thought I'd share some that I thought were farily useful (most related to running VMware Server on a Linux host).
