Unfortunately, a replacement card cost me $100 (thanks Meriton!). Armed with spitefulness that could power a thousand suns, I took it upon myself to better understand how NFC works and how to read cards in Linux (libnfc is unofficially supported in Windows, but you’re on your own) This guide isn’t about cloning cards, breaking encryption using mfcuk or mfoc but it is about installing libnfc (which is required by those two tools) and using the PN532 NFC module.https://blog.sknk.ws/code/demos/Wed, 24 Feb 2021 23:38:01 +1100https://blog.sknk.ws/code/demos/Below is a small collection of graphical demos that I’ve written using the Ebiten framework. Currently it’s just a water ripple effect, but I plan to write more over the coming months. Particularly 2D old school demoscene effects that I come across on the internet.

It’s exceptionally easy, and relies on a judicious use of 37 different colours, ranging from coldest to hottest.

Rules: Any live cell with two or three live neighbours survives. Any dead cell with three live neighbours becomes a live cell. All other live cells die in the next generation. Similarly, all other dead cells stay dead. Over the 50 or so years it’s been studied to death, and is infact Turing complete (you can even play Tetris with it!https://blog.sknk.ws/blog/2019/03/04/upgrading-my-hp-mini-110-with-better-wifi-the-hard-way/Mon, 04 Mar 2019 01:00:00 +0000https://blog.sknk.ws/blog/2019/03/04/upgrading-my-hp-mini-110-with-better-wifi-the-hard-way/or, how I got rid of the pesky 'Error Message: 104-Unsupported wireless network device detected.
