Last November, NASA's Voyager 1 sent home garbled data, and engineers traced the problem to the flight data subsystem (FDS). The problem turned out to be a single chip in the FDS memory. They couldn't repair the chip but could move the affected code into sections and store them in different parts of the FDS system. They tested the new system this week, sending signals to the Voyager 1, 22.5 light-hours away. It worked, and Voyager 1 is back.
Is there some term for ultrabright LEDs? Talking about those you most likely need a cooling solution for, that output 50+ lumen (around 200.000+ mcd) on a tiny surface. Ebay isn't helpful with its search right now. Need something to attach next to the webcam so the OctoPrint cam can actually see stuff. #diy#engineering#3DPrinting
Reader, my grad school lab group has a paper due Monday and I am the sole contributor thus far. Just added figure 5 and I'm at 3 pages. #engineering#gradschool
Elecia( @logicalelegance ) and Chris( @stoneymonster ) talk about the Embedded Online Conference, their experience learning Zephyr, and some listener questions.
About a third of the way into the brilliant HOW INFRASTRUCTURE WORKS by @debcha and I appreciate the wonder at energy storage, a subject in which I've been lucky to make a career.
Also very much appreciate her eloquent debunking of the desirability of off grid living. At first the independence sounds like freedom, but in reality it's just doing more work by yourself. (And only so long as your tech functions!) True freedom is what we build together.
And here's the direct YouTube Link to my latest video., featuring the history of the Hydro Scheme, and the problem of what to do with Castle that once belonged to the Bruce's.
Boilerplate code is not a thing. Most "boilerplate" code is already covered in a library or package, and it should be used there. Otherwise, there are situational edge cases to be covered.
And unit test code is not boilerplate either. The point of unit tests aren't just to verify, but to explain problems when a failure happens. Unit tests without this are test theater.
Japanese mathematician/creator Yosuke Ikeda designed this innovative signboard. It’s a clever use of mechanical engineering to merge form and function.
The terrible human toll in Gaza has many causes.
A chilling investigation by +972 highlights efficiency:
An engineer: “When a 3-year-old girl is killed in a home in Gaza, it’s because someone in the army decided it wasn’t a big deal for her to be killed.”
An AI outputs "100 targets a day". Like a factory with murder delivery:
"According to the investigation, another reason for the large number of targets, and the extensive harm to civilian life in Gaza, is the widespread use of a system called “Habsora” (“The Gospel”), which is largely built on artificial intelligence and can “generate” targets almost automatically at a rate that far exceeds what was previously possible. This AI system, as described by a former intelligence officer, essentially facilitates a “mass assassination factory.”"
"The third is “power targets,” which includes high-rises and residential towers in the heart of cities, and public buildings such as universities, banks, and government offices."
It was easier to locate the individuals in their private houses.
“We were not interested in killing operatives only when they were in a military building or engaged in a military activity. On the contrary, the IDF bombed them in homes without hesitation, as a first option. It’s much easier to bomb a family’s home. The system is built to look for them in these situations.”
