Can Snakes & Ladders last forever?
Several Christmases ago I found myself horribly bored. I was stuck at my
mother-in-law's house. In the absence of anything else to do, my kids and I spent
the morning playing Snakes & Ladders. They found it dull. I was about ready to
jump through window just to escape one game that just never, *ever* seemed to end.
Childrens' Game to Punish PCs
Snakes and ladders is a boring game. But just how boring, exactly? Is it possible to bore a computer so much that it self-destructs?
Let's try it and find out...
Tidy Caseless Ordering in Django
Sorting by name in Django is a common admin annoyance. By default upper-case names come before lower-case ones because of their raw ASCII encodings. This isn't fun to try and explain to clients.
For years I've ordered my models using a forced lower-case slug, but sometimes you need the big guns: database functions. Let's use that powerful ordering, while keeping our code nice and neat.
AVR Multi-Programmer
I'm about 10 years late to the party, but in this project a cheap Arduino UNO clone becomes a very handy AVR programmer for everything from a little 8-pin ATtiny13 to a 28-pin ATmega.
Automatic Low-Voltage Cutoff
Running a battery completely flat can permanently damage it, lead-acid and lithium-polymer types especially. I put together this circuit to protect a small lead-acid UPS battery. It's cheap, has a high current capacity, and use only very common parts. Did I mention that it's cheap?
