John's Scheme Stuff

Disclaimer: I am not a scheme programmer. The code here requires Gauche unless otherwise noted.

• Listens for UDP packets from a temperature gizmo Bill built and connected to the network. udplogger.scm
• Grab and parse the HTML page from Bill's gizmo. gettemp.scm
• Postfix log scanner. Used briefly. Probably broken. Scary. scanpostfix.scm. Newer version which might be slightly less scary. scanpf.scm.
• Code to handle web sessions ala PHP sessions. session.scm
• Web Bulletin Board Code written in scheme. Uses session.scm. Very dangerous do not run for real. bulletin.scm
• Less dangerous bulletin board code. bulletin.tar.gz
• Reads an email header and makes a list of field-name/value pairs. mime.scm
• Parse dhcpd.leases file. leaseparse.scm
• Load server. This one uses scsh. serverload.scm
• Gets the load from a list of servers. This one uses scsh. getload.scm
• Starts a job on a machine using ssh if the load is below a certain threshhold. This one uses scsh. jobstart.scm
• Makes an HTML table of clickable thumbnails.imagegrid.scm
• Makes an HTML list of clickable files in the current directory.makeindex.scm
• Goofy SMTP tester thing.testsmtp.scm
• SASL interface for scsh/scheme48.sulv-sasl-0.1.tar.gz
• Program for displaying simple generated 3D data
• Super simple 3D rendering of plain PGM files. Sample data.
• General purpose form handling programs written using gauche and fastcgi. reuapp.scm, readreuapp.scm. Snappy CGI response on a PII 350 without having to write code in an annoying language. Gauche+fastcgi is your friend.
• checkprinter.scm. Thing to get some stuff from HP printers using net-snmp.
• templog.tar.gz. Gzip'd tarball of code used to capture sensor data, stash it in database, then emit a PNG plot of the data. Its an exercise in dealing with hot database action using Gauche because Gauche > u++.
• ejabberd_extauth_saslauthd.scm. External authenticator for ejabberd which talks to saslauthd.
• testextauth.scm. Tester program for ejabberd extauth programs.
• arp.scm. Fetch stuff from the ARP table of a switch.
• arpdb.scm. arp.scm which uses the db layer to stash the stuff using SQL.
• findred.scm. Find red pixels in a raw PPM file with 8-bit or 16-bit RGB values.
