I posted this but do not agree (entirely) with its characterization of "no value was delivered" by the data-driven trend. I think value has been delivered. But companies replaced their actual strategies with "just optimize X thing", customers began to feel like cattle, and just left.

Companies often optimize what is easy to measure, not what's actually important.

> but the buses are still mostly empty except for students and laborers who live outside the city.

You take the bus so this goes without saying but, let's say a bus is mostly empty and has 8 people inside. If you were to put those 8 people into individual cars, you'd make the road a lot more crowded. I think a lot of folks look at these mostly-empty buses and don't realize that most cars are mostly-empty also (average 1.5 occupants / car in most of the US, honestly probably lower in the LA area due to its sheer car centricity.) But of course if you're in a car you're more likely to view another driver as "someone like you" while you look at the bus and think of it as a waste of space and taxpayer money.
You'd think so.
In college, meeting someone that was better than me by every conceivable metric. You'd think that he beat me at one thing by neglecting another, but nope, the guy was excelling in every category. Perfect grades, involved in many communities, and generally pleasant to be around. There was no caveat, no excuse. Dude just straight up rocked.

I have met more people like that while travelling. I felt badass riding my motorcycle super far, but wherever I went, there was a greater badass riding along. Some of these travellers were on much longer journeys, on much smaller budgets, on a much worse bikes, riding offroad all the way, camping every night. Some were on bicycles, going around the world under their own power. I was just a rich tourist with a great bike who slept in hotels.

In a way, meeting those people was liberating. I will never be a world champion at anything, so I might as well play for the love of the sport.

I’m learning swing dancing. It’s been humbling.

It’s humbling because all my life, I’ve been really good at technology - I specialize in biotechnology and manipulating DNA, but am also fluent in programming (mainly python, go, lua) and am able to build hardware - even helped run a robotics startup for a while. Anything related to technology and science comes easily and naturally to me. This isn’t to brag, but just a fact that learning things has mostly been something I do way, way faster than my peers.

But I’ve never danced before, or done anything that required that particular skill set - then realizing I’m real bad at it. Seeing all my peers learn faster and be better, with the same amount of study and practice time, and really trying my hardest and just not being good at it. I’m really thankful for this experience! And I really enjoy dancing, and will definitely keep doing it!
Rust? Why not just JavaScript? It's far more functional than Rust and is much more widely used and deployed.
The link seems to address that concern. It reads to me as if the view is that if the concern can't be shared with the group then it needn't be shared at all. Discussing it in the group benefits everyone because everyone can hear the concern and the response to it.
Does it's popularity come from it's functional foundations or just because a billion dollar corporation keeps it up to date?
Definitely. Mentorship is symbiotic. I'll even argue therapeutic.

I lacked a lot of it through both work and personal lives. Simply left to figure things out. That, of course, had some impact. Certain skills are strong, others are weak.

I feel that's why I do well at SRE. Natural paranoia and so on. It also makes me goal oriented to the point of being nearly anti-social.

Overall, I'd say I'm worse off for my experiences. It makes me great when the sky is falling. It pretty much always is.

Due to that, I try to reflect and teach as much as I can. I'm one of the fortunate ones. While I'm here, I had to leave a lot of people behind. They can't speak at all.

That sounds like a war story, but aside from the 'atomic family', I'm really just talking about people who quit/moved elsewhere.

Filtering exists in the real world (work/personal), too - not just college. The things we do, and don't do, apply.

A weekly social event would do me a world of good, but I can't. That part of me is broken. Dress it up with work and I'm fine.

Helping people actually helps me. To hear that, no actually - my help isn't enough, was grating. It was wrong to take personally. Soft spot.
The claim that Rust makes the safety of 20% of code worse requires some justification. It is utterly contradictory to my experience. Having to do a dynamic check (an array bounds check, or `Option::unwrap`) does not make code "less safe".

Yep! Growing up in the American Northeast they are a prominent education module because it's an easy field trip :D
At undergraduate level I studied Physics and Astronomy, and then did a research MSc as an optical astronomer, which I hated and drove me away from Physics and Astronomy as a whole.

I spent a few years working in IT Support before deciding to go back to University to study Spacecraft Engineering at Surrey University. Which was a wonderful course, that gave an incredible overview of how one builds a spacecraft. More than most of the Master programs I have seen in the field since, the guys at Surrey had very real experience building quite a few spacecraft, which shone through in the projects and courses.

After that I started a PhD in Southampton that had an industrial sponsor, who eventually ended up offering me a job to build spacecraft before I finished the PhD itself (which was a little complicated in itself), which I took.

After I started with them, I basically apprenticed under an experienced AIT engineer who was coming up to retirement. This is where I really learned a lot. If you ever get the chance to work under someone in the later stages of their career, you really can learn a lot from them.

That was at OHB Sweden, which was an excellent place to see a broad range of things in the industry. I go to work on multiple spacecraft and various stages of development, from proposal, to qualification, to final assembly and test, and to launch as an operations engineer. Really a super experience I am not sure I could have been luckier ending up there.

After that I joined a very small team building the ispace lunar lander, which I am fairly certain will remain the pinnacle of my career. Never have I worked with such a great team on a great project. Everything just worked between us, and a small team really achieved something spectacular (even if it ended up in a crater on the moon).

Now I am working in Ireland for a data acquisition system developed for flight and launch vehicles. Learning the ins-and-outs of ethernet communication and analog circuitry. So far my complete lack of understanding of electronics hasn't been a problem, somehow.
Specifically, I think the original code will always do what you expect as long as sizeof(long) == sizeof(float), and the alignment is the same. In reality no compiler is gonna do weird stuff unless your hardware target is weird.

Well, considering the author is Nancy Pelosi's biographer, and nobody involved disavowed the story in 3 years despite its very widespread circulation, and how much the American MAGA right has dissected it since, I'm not quite sure why it would be that hard to believe.
Also I don’t think some of the points the author makes are accurate. Long range strike missiles like Storm Shadow or ATACMS and air defense systems like Patriot have performed well on the Ukraine battlefield.
It was the article author's choice to specifically say there is no safe systems programming language other than Rust. If that is not true then it's worth citing in discussion of the article.

Nope. It used to be a home baked solution that was totally unrelated to (and pre-dates) Zephyr. I believe that is the one that is still in the ChromiumOS EC repo, but for the last year or so, it's a Tock-based system.

I don’t think I’ve ever encountered one of these particular things objects, but I observe two things:

1. There’s no radiation symbol or mention of any radiation source in the picture.

2. From looking on Wikipedia, this type of device looks like it’s meant to measure radiation, and there’s no mention of any reason that it would contain a radioactive source. Household smoke detectors contain ionization chambers and a radiation source, but they seem to be separate devices.

Is there any reason to believe that this thing contains a radioactive source?

As you say, things shift around, promises get made, everything gets delayed and all of a sudden there is no margin left. Unfortunately AIT has to do all of the hardware work with no margin so much of the time.

I was in my early 20s talking with a friend who was at least twice my age. I was bitching about a guy who'd look at the work I was doing who really didn't know squat about it and start telling me how I should be doing it.

After listening to me for a bit he quietly said "Well, you can learn something from everyone if you focus on that."

I spent a couple days pondering that. At first I tried dismissing it because he wasn't there when the guy I was whining about was blabbering on and on, and he didn't know the guy, but it kept bugging me and after a few more days it occurred to me that if he was right I'd been missing out.

Just a few days later the guy I was whining about came by again and looked at the work I was doing told me he knew a guy who could do most of that for me and it wouldn't cost as much and I could get it done a lot faster. So I went and talked to the guy, and sure enough he could do it, and do it faster and better, and it cost me a lot less.

I ended up making a lot more money on that work, and the company I was doing it for was thrilled with the changes. And since then I've focused what I can learn from others, even those who tend to annoy me.

Interesting, thanks for mentioning CUSE. If I’m understanding it correctly, it seems like it would be a perfect solution for this.

Learning that some folks can produce so much value with crappy code.

I've seen entire teams burn so much money by overcomplicating projects. Bikesheding about how to implement DDD, Hexagonal Architecture, design patterns, complex queues that would maybe one day be required if the company scaled 1000x, unnecessary eventual consistency that required so much machinery and man hours to keep data integrity under control. Some of these projects were so late in their deadlines that had to be cancelled.

And then I've seen one man projects copy pasting spaghetti code around like there's no tomorrow that had a working system within 1/10th of the budget.

Now I admire those who can just produce value without worrying too much about what's under the hood. Very important mindset for most startups. And a very humbling realization.

> The Cat even allowed you to include computer code in the middle of a document that could be executed with a button press.

I miss the 1980's. If I recall correctly, Raskin conceived the Macintosh as a computer that was easy to use for ordinary people yet also incorporated the means for ordinary people to program the machine. The solution was to make it easier to program. (Something that was added as an afterthought to Jobs' re-envisioned Macintosh with Bill Atkinson's Hypercard.) The general view was that those who used computers should be creators, not just consumers.

Contrast that to modern computers. While most can be programmed by the end user, the entry points are rarely obvious. The vast majority of languages that are easy to learn are regarded as learner or toy languages. Many of the professional languages are several orders of magnitude more difficult to use than their equivalents in the 1980's (often for good reasons, but it doesn't help the cause).
JDAM failure could also be linked to the lack of air superiority, or parity, and who know's how well they work with Russian aircraft.

What strikes me is the continuous propaganda that gets traction somehow, to try to plant the idea that "oh the help US is giving... isn't doing much... so expensive and not worth it... just look at Russia, they are going great! Might as well just stop it... "

When in reality we're witnessing a stage of war where Russians are using dirt bikes to make assaults. You don't need to be a war expert to understand why dirt bikes are a bad idea, and the video records show why... it's a complete disregard for human life.

The Russian regime has no respect or value for Russian's lives. I can't believe we're witnessing this level of atrocity only motivated by the personal interests, of both the regime and Russian volunteers.

With that said, US Weapons from the 80's, 90's and early 00's are doing great. Could they be doing better? Of course, but what would be the alternative? A mass scale genocide unlike we've seen since the Holocaust.

Edit: Ok I just looked at the "Responsible Statecraft" website, it's filled with Russian propaganda. They continue to frame the responsible party for the invasion of Ukraine is the US and NATO. This website should be banned from posting here.

From the article:

> Servers store passwords in the form of hashes, so even if a hacker steals the database, they see the hashes, not the actual password.

So as I understand it, the article assumes that someone hacked a website where you had an account, and want to get your password (for the hacked website), in order to try using the same (username and) password to get access to your account on other websites.

Or, as other comments mentioned, they might intercept wifi authentication packets (which contain hash of the wifi password), and try to get wifi password from it.
