There are linux kernels out there being used for all kinds of real time applications including rockets and radar, so as much as elon musk is an idiot I wouldn't really worry about it.

yes, please never forget that the formative experience in young elon's life, the thing that made him want to become an entrepreneur, was when he stole an emerald from his dad's safe and took it down to a jewelry store and sold it, and then a week later walked by the store and saw that the emerald was now set in a ring that was being sold for four times as much as he got, and he thought that was tremendously unfair and he wanted to be the person reselling the emeralds for 400% profit, not the chump who supplied the raw materials. like literally this is a story he tells. i am not making any of this up. just young elon skipping down the road with pockets full of emeralds, as you do

Also as someone pointed out elsewhere, his family left SA upon the end of apartheid, never to return...because who needs to stick around if you can't have slaves?

Elon Musk grew up in apartheid South Africa, I have this feeling that growing as a white boy in a place like that must gently caress you up somehow. Just look at Oscar Pistorius.

Lots of people already beleive that since MLK did peaceful protest, the moment a punch is thrown or a trash can tipped over that protest is Just As Bad As The Problem and Who Is Violent Now. Those people already all believed that. They're going to keep on beleiving it. They're a given and their views aren't changeable. These people freaked out over a sports man adopting the wrong body posture during a song. They disagree that the problem exists, there is no protest "peaceful" enough for them. On the other hand, "black man murdered by cops -> police precinct burned down" is a solid way to illustrate that the problem does actually exist. Furthermore, it's a way of demonstrating the value of George Floyd. His life (and death) was worth burning down a public building. Applying a cost and value to life is good. Discarding and ignoring it is bad. If people want the police buildings to stop burning down, perhaps they could help the cops stop murdering people.

The police of going Michigan walked with their citizens, a group of people who have every right to distrust the government that failed them. It was joyous. That is all they had to do but they wanted violence to start their racial holy war.

And it's extremely bullshit that they believe that in the first place because all being peaceful got MLK was being blackmailed by the actual FBI until they gave up and just loving killed him.

Mozi posted:Here's a fun one for you, from my backyard. Two ancient maples, one dead, one hanging on. The dead one hanging on as well, actually... Yeah, that's a nasty hang up. If it ain't a threat to property and you, gently caress it, it's habitat for the birds. Probably one of the neatest things I saw while doing that job was, while on a lunch break, I watched a bunch of ants make a chain and slowly pull a very fat grub out of the stump of a tree to eat. Those little fuckers are strong. I mark trees for tree crews for a living nowadays, so all the experience from my time as a trainee and trainer Sawyer comes to mind regularly. I'm honestly glad I never got into arbor work, sure the job I do now doesn't pay near as well, but the worst thing I have to deal with nowadays are dogs and angry customers.

zedprime posted:Ionizing is very spatial and the wires to and from a microcontroller and other spatial orientation mean you aren't going to flip or fry the same bits in identical hardware receiving what is functionally measured as the same general dose. Voting is valid (and again required to hit your probability in the FMEA short of a lead casket) way to manage something probability based like that. Just about everything votes on a spacecraft unless it's a very simple ionizing proof device. Depending on the weight of the microcontroller you start seeing ridiculous stuff where the weight tradeoffs means you have weird poo poo like 5+ voters. You don’t have to fry the voters. You just have to flip a few bits in different places so that ECC fails in different spots on different voters. That’s way more likely to happen than a solar storm. We’re actually bombarded enough at ground level that bit flips are guaranteed. All you have to do is get all three voters to disagree in a calculation before your scrubber processes can repair the damage. It’s basically a race. The best strategy uses rad hardening, voting, hardware ecc, software integrity checks, and hardware watchdogs.

Yep, if you run at HPC or datacenter scale, you are pretty much guaranteed a bunch of flips. ECC will catch and even fix many of them, but high energy particles have the tendency to not just flip one bit, but a whole bunch of them on their path as they pass through. A 14nm Xeon hit by a high energy particle will get much more than a bit flipped, which is why hardened logic is etched at much older process nodes (280? ceramics?). One related anecdote I hear was at an HPC conference keynote from a Blue gene/Q center director. A clients just was not getting the expected performance, and at the end they found it out it was not due to faulty hardware, but because of the latency introduced by ECC-RAM fixing soft error events. At such scale, you are pretty much guaranteed at least one will happen on some of your racks for even the tiniest of time windows. It's not much, but the client's computation was in a Bulk Synchronous Processing style, so a straggler thread causes the rest of your bazilion threads to do fuckall for a while. edit: Mandatory radio lab episode on bit flip changing election results: https://www.wnycstudios.org/podcasts/radiolab/articles/bit-flip Although it could still be due to lovely coding.

Movin' right along. Footloose and fancy-free. Getting there is half the fun; come share it with me. Moving right along (doog-a-doon doog-a-doon). We'll learn to share the load. We don't need a map to keep this show on the road.

ohhh I was wondering why he had one already but with no clip, I thought maybe it was his that he brought Apparently the dude who looted it was actually firing it into burnt out cars? Which is loving stupid. Security guard showed more restraint than a cop, but the dude was white I guess ¯\_(ツ)_/¯
