Constantan has a zero temperature coefficient of resistance (or I guess resistivity) because it incorporates Weston’s Alloy No. 2, which has a negative temperature coefficient of resistance. Or something? I don’t quite understand. This is what Thwaites tried to use for #bootstrapping his toaster heating element because Erin Brockovich scared him away from chromium. #materials

#Facebook exercised #censorship against the video of the #Philando-Castile #Minneapolis #extrajudicial-execution, temporarily deleting the video and the entire account of his girlfriend, who filmed the #police killing him as his four-year-old daughter was in the back seat. “It’s okay mommy. It’s okay, I’m right here with you,” said the four-year-old. “We’re very sorry that the video was temporarily inaccessible. It was down due to a technical glitch and restored as soon as we were able to investigate,” a Facebook spokesperson said. #human-rights #right-to-record #death

#Tesla claims its #self-driving-car autopilot has “better than human” performance. Well, that’s hardly surprising when it requires constant human supervision.
A database that stores stuff in a text file; the format is (almost) blank-line-separated RFC-822 headers. “#Recutils is a set of tools and libraries to access human-editable, plain text #databases called recfiles. The data is stored as a sequence of records, each record containing an arbitrary number of named fields.”. recsel -e "Age < 18" -P Name acquaintances.rec to select names; recins -f Name -v "Mr Foo" -f Email -v foo@bar.baz contacts.rec to insert. There’s an Emacs mode, but it’s not part of standard Emacs (or very powerful, I think), and there seem to be some problems in the interface. Supports some minimal integrity constraints including range checks, uniqueness, and regexps, but not referential integrity (foreign key constraints). Supports references to other records via a primary key with an ad-hoc convention for fields thus obtained, but not arbitrary joins. Has its own mail-merge template syntax for reports.
