Arranging atoms and pressurising air in a variety of manners, such as:

Pronouns: they/he

  1. Black sesame seed ice cream went down well at the office, has replaced chocolate as my favourite ice cream flavour (those of you have eaten ice cream with me will get how big a deal that is)

  2. Posting this note from barnabywalters.bit — been experimenting with namecoin, got .bit domains resolving on my machine by following instructions namecoin.bitcoin-contact.org, installed namecoin wallet on my VPS and registered a name, pointed it at my web server.

    Surprisingly it was a fairly straightforward process. The most difficult part was getting hold of some namecoin to register names with — I ended up trading some of my DOGE for NMC on vircurex.com.

  3. I am inordinately proud of this tiny progress bash snippet:

    watch 'echo "$(namecoind getblockcount) / $(curl -s http://explorer.dot-bit.org/stats/block_count.txt) * 100" | bc -l'
    
  4. Prepping an old machine for demoing crypto tech at the cryptoparty tonight, windows being a complete pain. I have a feeling I’m going to be spending most of the evening apologising for other people’s bad UI decisions.

  5. Barebones PIC Programming on Mac + pickit2

    If you’ve never done any microcontroller programming, start with an arduino.cc. It’s the best way of getting started with embedded hardware programming.

    If for whatever reason you’re determined to use PICs (cost, availability of free samples, you already had a bunch of them, etc.), you should get a pickit3 and use the netbeans-derived MPLAB X to develop, program and debug your devices.

    But if like me you’re in the weird position of having a bunch of PICs, a Chinese knockoff pickit2 and a strong dislike of Java, here’s how to set up a *minimal* C development environment on a Mac.
