A free-software #Forth operating system running on the J1a open-source CPU running on a Lattice #FPGA thanks to Project #IceStorm’s reverse engineering and the resulting free-software #synthesis and programming toolchain, running on the Lattice iCEstick evaluation board with 8K of RAM. #J1 #hardware
A 2009 #video lecture series on #mecheng manufacturing processes by “nptelhrd”, Prof. Inderdeep Singh at IIT Roorkee. Some problems with the audio, seems to be a bit clipped. However, the video is entirely a talking head and a bunch of PowerPoint slides, so the only way you would watch this video to learn about powder metallurgy instead of reading a book is if you are dyslexic or have a beard fetish. At least it doesn’t have shitty elevator music.
The USGS gives #pricing information on a variety of mineral #materials, including some historical stuff. #minerals
#Titanium #pricing in the US has gone from US$9.62/kg in 2010 to US$11.20/kg in 2014. Nearby pages use dollars per pound, but the prices per kg show a sharp reduction from its peak of US$17.28 in 2005, but it had a low of US$6.50 in 2003, US$9.70 in 1995, and US$8.26 in 1992–3. This means that the FFC Cambridge Process is not in production yet.
A #PDF with a bunch of metal #materials #pricing for 1970–2010. Comprehensive, covers nearly all metals and some semimetals. Unfortunately at least some prices use folk units like pounds instead of SI.
Rebecca Solnit talks a bit about #rape and #intimate-partner-violence. #feminism
The FCC is proposing to outlaw #free-software for wireless firmware.
Programmers competing to do Intel 8086 (subset) #emulation in different languages, including a C program in 348 lines.
