  • More haskell morse code. This time with audio!

    Today I added audio support to the morse translator that I made yesterday. There ought to be a screencast of me demoing it, but screenr is being a dick, as it sometimes is for no discernable reason. I found the admirably minimalistic Data.WAVE library with a little bit of searching. This

    Recently, nor and I went with her family to Bletchley Park. Nor’s grandmother used to be a radio operator at what we think was one of the Y stations, near Leighton Buzzard. She spent her time transmitting and receiving coded messages in morse code — in 5 character blocks of apparently

  • Using modsecurity with RBLs to mitigate comment spam

    Recent weeks have brought a pile of new comment spam on this site. I’ve explored a few ways of mitigating the amount of crap I receive, and hpoefully wasting some spammer bandwidth. This includes various lookups that are built into the code that runs the site, dodgy posts get timed out for a

  • PiPhone: A smartphone made of a Raspberry Pi

    A seriously cool idea this; making a smartphone out of a Raspberry Pi. A guy called Dave Hunt put together the PiPhone, using a 2.8 inch adafruit TFT touchscreen and a Sim900 GSM/GPRS module. The result is pretty sweet as you can see from the video.Dave did a PiPhone writeup on his sit
