Irrational Number About


My name is Aivars Kalvans. I write software (C, C++ and Python) that runs on Oracle Database and Tuxedo for more than 16 years now. I tinker with internals of Oracle and various other software and develop an Open Source alternative to Oracle Tuxedo called Fuxedo.

Some other code I have written both bad and “good enough”:

  • Scruffy UML - creates UML diagrams from textual description.
  • libvmod-rewrite - a plugin for Varnish (proxy server) that allows to modify cached pages.
  • pattern-matcher and cloud-instances are winning entries of Latvia Java User Group programming contest. The first one was written while I was still drunk after a party.
  • Scrapy proxies - Scrapy (web scraping framework) extension for using random proxies. Some people find it useful.
  • … and everything else on
