It's the UK's first Vintage Computing Festival next weekend, so I've been getting some stuff together for my Speccy exhibit. Of course I've been working on the Spectrum ethernet card, and while things like the network filesystem it provides are handy, I thought I needed something that VCF attendees could appreciate.
A while ago we did a "hack" of a Twitter client (over a pint of beer, in a pub in Oxford - while getting strange looks from all the "normals") but it was just that - a hack - with the tweet and the login details hard coded into a short asm program. This time I've written a proper http library, and some user interface. Most of the work is done by the HTTP library (parsing headers, putting headers into the request etc), and it's all written in C.
If you can't get to the VCF, you can at least watch a video here:
