Kragen Sitaker's home

It should be noted that my legal name is still Kragen Sittler.

This is a very bare-bones home page, intentionally. It'll get more organized when there's more to organize. My home home page is much worse.

• Some sounds of me whistling.
• A command-line dictionary lookup program that uses the web; there's a fetcher and a postprocessor, available in a single tar file for convenience; they're written in Perl, use netcat, and were tested in Linux. Last updated 6 October 1997.
• An example of binary trees, for a friend of mine who wants to learn how to program. Last updated 21 September 1997.
• A searchable index of the RFCs, last updated 2 September 1997. It's just a webbification of some command-line stuff I'd put together.
• My résumé, last updated 18 August 1997.
• Firesides my wife and I hold each Monday, last updated 19 August 1997.
• Xraw, a GUI developed by someone else. Last updated July 1996.
• My wedding
• my documentation for qmail's stralloc
• prototype macro language for the WWW
• cheapo Markov-chain text modeler
• X is Pretty, last updated 20 September 1997
• Real News (unimplemented!)
• My LILO configuration file, which is here because I posted about it to linux-newbie. It shows how to have a choice of multiple kernels to boot.
• Database thoughts.
• A desk calculator, written in Tcl with Tk. Little functionality so far. If you have the Tcl plugin, you can use it in your Web browser at calc.tcl.
• A slide rule, in case you don't like digital calculators. Also viewable in the plugin. Only A, B, C, and D scales so far, and no pi yet.
• Dumb actions.
• Some thoughts on programming.
• An example of hashing I wrote in C++ for a friend of mine who wants to learn how to program. 4.6KB, last updated 13 August 1997.
• Another programming example, demonstrating backtracking, etc. on the map-coloring problem. 94KB, last updated 21 August 1997.

Dynamic DNS

This is somewhat obsolete now; instead of using this, as of August, I'm using the dynamic-domain service at Monolith. So the below is on hold.

I wrote a simple DNS-update server in the first week of May; it's currently locally tested and working OK. I'm looking for a place to test it outside of my home machine; I need a machine that has a static IP address and I need a DNS delegation from somewhere. It's able to run as part of a multi-zone production nameserver, but it does need to be able to send signals to the nameserver.

The code is available in dynamic-dns-toy-3.tar.gz, which is less than 10K. It's mostly written in Perl, except for the start-server shell script and the sighup-named.c program, which runs as root, and is written in C. A Linux-2.0.0-ELF binary is included.

If you decide to use or test it, please keep in mind that it's pre-alpha code; let me know you're using it, so I can incorporate fixes for the bugs you discover back into the main source.
