The last time the fires hit my area I was watching the fire progress via Purple Air sensors. If this one sensor was still sending, then my friend's place up in the mountains was probably OK. Seems ... kinda obvious almost?

The hard-to-solve problem with the news is that reporting on suicides causes suicide (as in: more people commit suicide, not just people who were on the ledge decided to go) yet people also want to know things.

I'm unclear if the usual disclaimers added to the article actually help or just are the only sounds-like-it-might-help thing that comes to mind so at least the publisher can feel better about the added deaths that, statistically speaking, they might be causing. I just remember it being covered in one of my college gened classes and the way it was presented was that everybody threw up their hands in frustration and gave up.

An acquaintance who screwed up her leg really bad and went through a whole process of getting bolted back together et al decided that she wasn't going to tell people what happened. Because everybody always asks "how'd you do it?" as if it was some curse that she had personally triggered that they could avoid. And I thought about how the first question in my mind was "how'd you do it?" and I guess it made me think about the inanity of making sure to check for flying herring while traveling backwards hanging out the window of a train going between Albuquerque and Phoenix after having signed up for a triple indemnity life insurance plan.... or something like that.

The only exception, of course, is you are doing something that the news orgs consider "wrong" like doing drugs or being certain categories of mentally ill or riding a bicycle for transportation.

Well, one option, which can be pushing the boundaries of selfhosted for some, would be to use a hosted k8s service for your public-facing stuff and then a home real k8s cluster for the rest of it.

A few years ago now I was thinking that it was about time for me to upgrade my desktop (with a case that dates back to 2000 or so, I guess they call them "sleepers" these days?) because some of my usual computer things were taking too long.

And I realized that Intel was selling the 12th generation of the Core at that point, which means the next one was a 13th generation and I dono, I'm not superstitious but I figured if anything went wrong I'd feel pretty darn silly. So I pulled the trigger and got a 12th gen core processor and motherboard and a few other bits.

This is quite amusing in retrospect.

From the article: "Tesla began delivering the Blade Runner-inspired truck in November 2023"

Me: Fuck you. That is an insult to Syd Mead's legacy.

It's the Pravda of the VC-centric tech scene and has been for a very very long time.

(I am referencing the Soviet Union implementation thereof, for clarity)

It's never going to bite the hand that feeds it, where people will voting-ring or the owners will just force-edit it to prevent that from happening. Outside of that, sometimes it might say something useful. The problem is that today's problems are not because of a lack of advanced mathematics understanding or new programming languages.

I mean, I think he's a textbook example of why not to do drugs and why we need to eat the rich, but I can understand the logic here.

When you navigate a car as a human, you are using vision, not LIDAR. Outside of a few edge cases, you aren't even using parallax to judge distances. Ergo, a LIDAR is not going to see the text on a sign, the reflective stripes on a truck, etc. And it gets confused differently than the eye, absorbed by different wavelengths, etc. And you can jam LIDAR if you want. Thus, if we were content to wait until the self-driving-car is actually safe before throwing it out into the world, we'd probably want the standard to be that it navigates as well as a human in all situations using only visual sensors.

Except, there's some huge problems that the human visual cortex makes look real easy. Because "all situations" means "understanding that there's a kid playing in the street from visual cues so I'm going to assume they are going to do something dumb" or "some guy put a warning sign on the road and it's got really bad handwriting"

Thus, the real problem is that he's not using LIDAR as harm reduction for a patently unsafe product, where the various failure modes of the LIDAR-equipped self-driving cars show that those aren't safe either.

It's important to realize that the nerd you saw on the news has always been someone wearing nerd as a costume and the entire history of technology is loaded with examples of the real nerd being marginalized. It's just that in ages past the VC's would give a smaller amount of money and require the startup to go through concrete milestones to unlock all of it so there was more of a chance for the founder's dreams to smack up against reality before they were $230m in the hole with no product worth selling.

While there is arguably a larger pool of people who you can reach by not having open racism and the CEO whipping his dick out (and mysteriously not slamming it into his Tesla door, even if it is a masterful gambit) you can still get a lot of white men of privilege who are smart and hardworking who don't nominally worry about being on the receiving end of most of the harassment so it's OK as long as they end up part of the winning team because they'll get mega stock bucks at the end. And this does extend to the factory floor, at least people's impressions while joining the factory floor. They wouldn't be an engineer but they'll be a supervisor or something?

It's kinda un-earned? Like, there's stories that people tell each other of questionable veracity? Some set of startups in the days of yore gave their cleaning staff or whatnot options so I think it's become part of the cultural mythos now even if the reality is that the cleaning staff these days is contractors who are mistreated so even if it did actually happen then, it won't happen now.

And, dono, once you've solved the hard problems early on, there's less of that drive to do the truly novel things and so you get more of the people who want to be part of a company that's going to the top and wouldn't mind if they could coast and/or fail upwards along the way.

The problem is that employers tend to presume that they can continue to abuse people going forwards into the future because they've gotten away with it so far. Until they do things like yank offers from new college grads or laying off too many of the professional staff, at which point you've shattered the illusion.

tl;dr: Elon sowing: Haha fuck yeah!!! Yes!!

Elon reaping: Well this fucking sucks. What the fuck.

All things being equal, however, I'd rather they do the version more likely to remove themselves from the gene pool.

Masterful gambit, sir.

Okay, so understanding that Boeing has been shipping airliners that boing instead of fly or have some bolts missing...

My dad was a frustratingly retired aerospace engineer because there was this period of the 90s where we actually did shrink the defense industry until 9/11 and the contractors started figuring out exactly how to "bribe" people. And one of his side complaints is that any aerospace engineer is probably actually good at being a general-purpose mechanical engineer, except that they've generally made the hard stuff actually safe earlier along, but nobody will hire them. His example being fully-automated-digital-engine-controls and fly-by-wire and having three redundant chains.

So, in the aftermath of the whole Toyota throttle-by-wire thing that really didn't go a whole lot of useful ways, I decided to check out his observation and I did some googling to discover a page where some big company was advertising to the auto industry at large their throttle controllers. And they talk about how they were built with "aerospace technologies" to be reliable and safe. And, looking farther along, it seems like that was not actually three redundant chains, just three threads of execution on the same processor.

Oh yeah, and generally any airplane that does have fly-by-wire and FADEC there is going to always be a set of reversion modes and people have to know about them. Obviously some aspects of this are far stricter because a car can just pull over to the side of the road... but also it needs to do that safely. Witness poor Anton Yelchin dying ignominiously because of the digital gear shifter thing on his Jeep.

But, yeah, the underlying problem is that the cultural expectation is to make cars that will go most places containing capabilities that a vehicle might never actually use in its entire service life and require the minimum amount of knowledge and basically zero knowledge above the collective cultural understanding of a car that's only mildly changed since a fully-mechanically-linked control system.
