#video of Jack #Rusher’s talk “Stop Writing Dead Programs” where he starts showing his Fortran program written on a keypunch for a VAX 11/780. Approvingly quotes #pushcx (Peter Bhat Harkins) on programmers perpetuating pointlessly hard nonsense.

Ruth Starkman’s 02013 exposé on how “A highly qualified student, with a 3.95 unweighted grade point average and 2300 on the SAT, was not among the top-ranked engineering applicants to the University of California, Berkeley.” because of their “holistic review” to discriminate against Asian-Americans. Although he probably did get admitted. #racism #USA #history #news #toread #politics #admissions

#bigclive #video dissecting NiMH and lithium AA cells; the NiMH one is mostly empty space in the middle! They’re largely punched metal mesh separated by electrolyte-soaked fibrous separator which looks a bit like thick paper, with lots of powdery paste smeared into the mesh (presumably largely depolarizer). The last battery, a Lidl NiMH cell, caught fire spontaneously as he was disassembling it, but not due to a short circuit; not only was it theoretically fully discharged, but the bits of mesh material that caught fire had no path to the other electrode. I guess it was a pyrophoric metal hydride cathode. Rapid deployment of the Explosion Containment Pie Dish prevents disaster. “There may be a delay between exposure to air and spontaneous combustion.” #hardware
#video on Nordic RF #communications #electronics that can feasibly run off some largish photodiodes used as solar cells. “Ultra low power energy harvester from BPW34. Super small and durable power supply for wireless nodes” on hackaday. Also “Solar-powered flashing LED heart pendant PCB coil” by bobricius in 02018. This guy, "Pocket Concepts", got 300mV out of his BPW34 photodiodes, and used it to transmit a temperature datum over #Bluetooth #BLE to his motherfucking phone. His #Nordic chip uses about 50μC of charge (over the 2.25V to 3.6V range) to run for the necessary 20ms, so he needed 37μF, which looks like maybe it’s a tantalum cap. It gets enough power from his fridge light to send a transmission every few seconds (so, say, 0.4% duty cycle, so he’s getting tens of microwatts). But a slightly larger amorphous cell is even better because it works even in a dimly lit room. #electronics #solar #photovoltaic #energy-harvesting
