Multithreaded testing with JUnit

This post demonstrates an easy way to test the effect of multiple concurrent threads running your software, using your existing unit tests. Have you ever wondered whether your software is really thread safe? Whether it will stand up to the punishment of thousands of concurrent users when your site (or app) goes ballistic? Multi-threaded programming […]

linux firefox ipv6 snafu: FIXED!

I post this in the hope that it will save someone the headaches I suffered: I found that certain web sites were unusable (super slow – minutes to load) in firefox on linux, although retrieving pages from the command line w/say wget worked just fine – python.org, for example, and the firefox addons site.

a foot of water in the well

Like many of my neighbors, I came home to a basement full of water last night. First thoughts – all the stuff that would be ruined; we quickly abandoned the pile of childcraft books, the old rugs, some boxes of breakfast cereal that hadn’t been put away yet. But my tools, some lumber, the leaf […]

Scrapple

Play the scrapple word game against the computer, or play a solo game and try to achieve the perfect score. You will need to have installed a Java runtime environment (at least version 1.5) to use this applet-based program. Also don’t forget about the sudoku solver and the snowflake creator, all on the toys page. […]
