function screen-sessions {
   typeset -a sessions
   for i in /tmp/screens/S-${USER}/*(p:t);  do
      sessions+=(${i#*.})
   done

   reply=($sessions)
}

compctl -K screen-sessions screen

Completion chops off the PID of the screen session, so i can do:

screen -x log[TAB]

and it will complete to 'screen -x logwatch'

Hurray.

Got bored after doing some homework tonight and added a few more completions to my zsh config. The top two are yanked from petef's zshrc

compctl -g '/u9/psionic/Mail/*(/:t)' -P '+' folder
compctl -g '/var/db/pkg/*(/:t)' pkg_delete pkg_info
compctl -g "/tmp/screens/S-${USER}/*(p:t)" screen
compctl -g "*(-/D)" + -g "*.class(.:r)" java

What do they do? (Listed in order)

• for the program 'folder' complete to any directory in /u9/psionic/Mail/ and drop the path above it (like basename(1)). Also prefix it with a '+' character.

  fury(~) [1] !127! % folder +TAB
  drafts      exec        inbox       lists       old         rtp         spam

• complete package names under freebsd for pkg_delete and pkg_info

I got bored and wrote an expert system for doing log analysis and reaction. It's original intention was to watch auth.log for brute-force login attempts and block them on the firewall. It has turned into a far more flexible system for doing generic log-based matching and reaction. Reactions are based on a threshold of hits over time. The 'reaction' section of the config file specifies what command is run (this could be a simple shell script you call, for example).

There are a few features I'll probably be adding soon such as multiple threshold/reactions per match type, but that's somewhat down the road for when I have more boredom to throw at the project. I also want to allow users to add their own meta globs (like %USERNAME%) into the config file so the program is even more flexible.

Currently it runs on my mirror server and blocks excess (brute force) ssh attempts, seems to be going good. The development process of this took me into learning a very slick perl module called Parse::RecDescent which parses documents based on a given grammar. I used this for the config file, it was pleasantly easy to use. Check out logwatch, download it

It requires the following perl modules:

• File::Tail
• Regexp::Common
• Parse::RecDescent

My site is pretty much my ramblings, ideas, and projects regarding various computer technologies. I've always written my own website software myself becuase I needed features I couldn't find in blogging tools available at the time I was writing the code.

This time around, however, is a different story. There are plenty of blogware suites out there that have a varying array of features. A friend of mine recently started using Wordpress over his own software. I've checked it out and it's decent. However, it does simply blogging and little more by default. I need to explore more of it's options and i'll have to write a few of my own plugins, but it may be what I need.

Most of the work redesigning my current website has been regarding layout and extra content features. These being, specifically, cvs and darcs commit summaries, Furthermore, I tend to do one of many things, projects and blog entries. These are two different things, in my opinion. I need to be able to update project pages along with being able to write simple entries.

Wordpress seems to have these abilities via plugins and whatnot. So I'm going to be spending some time trying to configure it and write a few plugins so I can have various informations displayed on the front page, such as cvs and darcs repo commits, etc.

The search goes on, but for now we'll have to see how Wordpress fairs against my tests. Since Wordpress already meets one of my requirements, that it allows me to post things. It also has a plugin framework and themability, etc. I need a developer blog. And for me to consider using Wordpress I'm going to need to hack some functionality into it. So we'll see :)
