#ldgraphy mirror progress. thanks to +Henner Zeller for the laser cut mirrors. Unfortunately, my original idea of just supporting it at three points didn't work due to the mirror wanting to torsion itself back flat, rather than just unbend along its plane. However, by wedging it at the top and slowly (very slowly) tightening down the bottom things appear good.

3mm still feels a bit stiff to me, i cracked a couple mirrors. 2mm or polycarbonate mirrors would perhaps be better if i can find them. but 3mm acrylic works with some cajoling.

My poor lego 8880 supercar. Somehow all the parts became warped and now the gears won't turn.

Found a bunch of surplus old IBM keyboards with trackpoints in them! Now to see if I can extract the trackpoint in one and mod it into my happy hacking keyboard.

Nice, my home ISP is giving me full /64 ipv6 blocks. I'm pleasantly surprised how seamless it was, i just noticed all my machines were getting ipv6 addresses one day. I can now ssh into any linux box in my home now directly. sweet. Now why do I have the urge to write an IP stack?

Finally we can start on all those p2p crypto projects that have been hampered by NAT firewalls requiring third party trusted servers as well as break free from the TCP/UDP  ghetto with SCTP and DCCP.

I've decided no calculator comes quite close to what I want (the HP-15C comes closest) so am replacing the firmware on an HP calc with something better. The paper overlay is surprisingly usable, but laser cut vinyl stickers are the way to go once the layout is finalized.   #hp   #calculators   #math

I have released a new version of jhc, my optimizing haskell compiler. 

Fun stuff is targeting bare ARM hardware, a new license, and SIMD primitives.

Repurposed nexus 10 holding arm makes a great adjustable keyboard tray. Perfect fit for the happy hacking keyboard.   #happyhacking   #lifehack   #ergonomics   #monoprice
