"I find it really hard to believe there's not 3 more in the area that couldn't handle being an ATC operator."

They might be capable, but why would they want to?

"Why couldn't it be?"

Things like coordination and communication in high traffic environments don't scale well. Finding efficiencies in the procedures and systems can eliminate potential miscommunication and missed handoffs.

"And it's not like we don't already have 99% of the existing buildings, infrastructure, and computers already setup. It's literally just the personnel that's lacking."

Actually only some airports have been upgraded while others are waiting. Do you think another person would have prevented this incident? From the recordings and facts so far, it doesn't seem like it.
That's a reasonable path! You probably learned to appreciate and value the complexity, but you wouldn't have from the start. Which service do you use?
I assume you're referring to the 2 minute rule here. One of the main points of GTD is that you can just make a note of the interruption, so you don't have to deal with it right then, because you know it's waiting for you in a trusted system. (Which incidentally might just be a sticky note on your desk!)

Also, the 2 minute rule itself is flexible, just like the rest of the system. Sometimes it's a 30 second rule, and sometimes it's a 5 minute rule.

It was necessary and worth it.
I enjoy eastern philosophy but I'm not a fan of Harris. Why would he charge so much if he truly believes in reducing suffering?
I know. But I'm told they're calling "Aspergers" ADHD now. And the brittleness that comes with habitual focus looks like massive distraction. I mean you've got these guys who can focus to the point of magic, but one push and they crack.

And we're borrowing somebody else's terminology anyway. So don't expect precision.
People who can't walk would struggle a lot in a world where society didn't make accommodations for them to enter buildings, use restrooms, etc. The problem is that society is decently good at accommodating the very visible and tangible, but terrible at accommodating anything they don't understand. ADHD is hard to understand for most people and therefore they have no interesting in flexibility in the way they do for things they do understand.

Going through the treadmill of school followed by a career that all require strict schedules, punctuality, meetings, note-taking, difficult conversations, social norms, and hard focus-heavy work is really difficult for people with untreated ADHD. It's all extremely hard for me, and it's doubly hard because if I don't do this I will literally be homeless and starve and have no healthcare, and there's not a single employer or coworker that has ever given two shits about how hard this may be for me, and in fact some of them have actively punished me for vulnerability around this

The Excalibur 155mm artillery shell is supposedly subject to twice as much acceleration as the spin launcher, and it has a solid rocket motor. So it's probably possible. But solid rocket motors are less efficient than liquid fuel.
For sure. We need all types. ADHD people would have been naturally de-selected otherwise.

TCAS has limitations as you suspect. Below 1000 feet it doesn't make Resolution Advisories (RA) because of the very real risk that it could steer a pilot into terrain. Below 500 feet it doesn't deliver aural warnings, only the visual ones. These are both limitations of the tech as it exists right now, and in theory pilots should be aware of this and be extremely cautious.

Personally I'm in favor of the "Swiss cheese" model of accidents, in which a lot of errors might routinely happen, but they're blocked from leading to an accident by other measures. When however the holes in the cheese line up... boom. There's evidence that there was a culture of accepting near-misses along this route, there's evidence that the training flight ignored best practices, there was a single ATC person managing rotary and fixed wing in that airspace, it was night time, the jet was making an approach to the shorter runway, etc etc.

On any given night one or two of these factors might have lined up, but not all of that. That night however they all lined up, and people died. This notion of failure in depth is the driving force between the total nature of an NTSB investigation, they don't want to find the LAST failure, they want to find ALL of the failures.
The fascinating thing about isopods is that they have been around for 300 million years! They roamed a much different Earth along with dinosaurs, survived several extinction events, and are now a delicacy for humans, which may be their biggest threat yet. Wild.
The author of lzip goes into some degree of excitement on the reliability and recoverability of the lzip format compared to xz.

https://www.nongnu.org/lzip/xz_inadequate.html

I personally back up about a terabyte each week, and I use 7-zip because it has built-in encryption, which is required because of the HR data in the backup. Thank heavens for xargs -P.

I could use "openssl enc" combined with any pure compression utility, but I don't want to make decompression impossible if I get hit by a bus.
I doubt it.

The advice I've always been given in (admittedly: small) business startup sessions was "focus on quality rather than price because someone will always undercut you on price".

The models are in a constant race on both price and quality, but right now they're so cheap that paying for the best makes sense for any "creative" task (like writing software, even if only to reduce the number of bugs the human code reviewer needs to fix), while price sensitivity only matters for the grunt work classification tasks (such as "based on comments, what is the public response to this policy?")

Their reputation is being friendly to shareholders.

Shareholders brought a suit alleging Musk's pay package was inappropriate. It came out in the lawsuit that the people charged with negotiating with Musk were actually taking direction from him.

However you feel about that, I think it's easy to acknowledge that if the people negotiating on your behalf were being instructed by the counterparty, you probably didn't get the best deal you could. The court's decision was reasonable and probably would've been similar in any jurisdiction.

This exodus appears to me to be part petty feud and part cargo cult.

I am a huge proponent of zstd after I learned about it on HN.
I've recently had to compress a 12 Gb csv file. zstd took ~3 sec for compression and ~11 sec for decompression and got the file to ~1.1 Gb. Xz took ~3.5 min for compression(!) and the resulting file was ~740 Mb(I didn't measure the decompression time). I just realized that in most cases it's more efficient to use zstd, especially for file transfer.

The majority of OS that people use either have it installed or can be trivially downloaded to, so I see no point in using gzip nowadays, unless it is mandated by API

This has been my experience for a long time. Swift is nice but why would I waste my time working on a language that is too tied to the Apple platform even if it's open-source when we have more universal scripting languages like Python, or languages like Kotlin that are compiled but have more support (because I trust JetBrains way more than Apple at the moment), or languages that are most strict like Rust but have more momentum and safety?

They painted themselves in a corner. Apple being the best computing platform while trying to please everyone can never be a serious proposition. Either they are the best and everyone uses macOS, or we have to be so careful that any alternative is more interesting that what they propose.
Windows changing UI so often did soften the learning blow for me, when moving to Linux.

Especially nowadays on Linux where you I've only "needed" terminal for getting a graphics tablet to map and for a video card update. (I'm willing to ignore software development going to terminal, since serious software development usually goes to terminal on windows anyways) .

XFCE is quite good at being XP/2000 era gui. The version I'm using is practically XP except with local software search and workspaces.
I have so many questions..! (And maybe the answers are somewhere on the page, but its navigational paradigm is too atrocious for me to handle)

- how fast do you have to push something through the atmosphere to have it reach space?

- and, how fast is the lever spinning to reach that velocity? how precise do you have to time the release?

- after release, your lever is going to be pretty unbalanced. having seen what happens to an unbalanced ultracentrifuge in a lab (spinning a few grams of biological samples), how does this thing launch a 100kg satellite without wrecking the launch station?

- does this mean all the remaining angular momentum is in an opposite weight you discard simultaneously by slamming it into the ground? do you just sling the payload around in some ridiculously unbalanced manner?

- can you launch things with liquids (eg., fuel) at all due to crazy sloshing mechanics?
Before COVID, I worked for an international company, with people from various countries often working in the same team together. It happened that in my team, I was the only guy from my country. So whenever I needed to talk to my teammates, I had to make a call.

And yet, it seemed very important for the managers that I come every day to the office and make those calls from there, rather than from my home. They couldn't make even the excuse about people being in the same room, because we obviously were not. But if you make the rules, you do not really need an excuse.

Then COVID came, and impossible things became possible overnight.

Now they are gradually becoming impossible again. Except that more people are pissed off, because they remember that it used to be possible.

You said "Reagan fired thousands upon thousands of ATC because they dared to ask for proper wages." All I did was correct you, and I didn't do so rudely. The rational reaction would be, "Huh, this issue is more complex than I initially thought. I should learn more about it."

> I just take issue with it being something you'd apply to all crypto code.

That this discussion is happening at all in response to a blog post that begins by linking to https://www.cryptofails.com/post/75204435608/write-crypto-co... is amusing and concerning in equal measure.

I don't care if you write crypto code. I never said I cared if you write crypto code. But don't:

1. Deploy your code

2. Publish your code in a package ecosystem

3. Encourage other people to use your code

...unless it's survived the gauntlet of peer review and has a good rationale for existing in the first place.

The reason I proposed an onion model for this discourse is that there isn't a binary switch where "if you do X you are rolling your own crypto but if you do Y you aren't rolling your own crypto". The deeper you slice, the more danger and responsibility you've incurred.

People who think "it's fine to build a custom protocol out of cryptography bricks because I'm not rolling my own bricks" are the highest risk group in software developers. Even moreso because (as tptacek constantly points out) most vulnerabilities occur at the joinery.
No, they haven’t lowered the standard to graduate.
You got the basic physics, but don't you think they have considered these issues? It's why this is interesting at all : despite the very obvious difficulties they think this has a case.
Then again, speed and performance.

At my last job, updating a productive game server cluster took an hour or so with minimal to no customer interruption. Though you could still see and measure how the systems needed another hour or two to get their JIT'ers, database caches, code caches and all of these things back on track. Maybe you can just say "then architect better" or "just use rust instead of Java", but the system was as it was and honestly, it performed vey very well.

On the other hand, the game servers checked once a minute what promotion events should be active every minute from the marketing backend and reacted to it without major caching/performance impacts.

Similar things at my current place. Teams have stable and reliable deployment mechanisms that can bring code to Prod in 10 - 15 minutes, including rollbacks if necessary. It's still both safer to gate new features behind feature toggles, and faster to turn feature toggles on and off. Currently, such per-customer configs apply in 30 - 60 seconds across however many applications deem it relevant.

I would have to think quite a bit to bring binaries to servers that quickly, as well as coordinate restarts properly. The latter would dominate the time easily.
I like the tooling but this doesn't change that the language has a major case of OOP-brain
I don't know about Xcode, but Swift is open source with an active community so if it doesn't work for you then you can definitely bother the Swift Open-Source project with a pull request or a proposal for a language or tooling improvement. You can also have a discussion on the forums or in the bug tracker with fellow contributors.

You can also make the change in your own fork and use that.

This is exactly how for example the Rust or Python open source projects work. And like those projects you can look at the Swift proposals and code to see _numerous_ cases where people did bother to bother the team with change requests or directly contributed to those improvements.

It is all open source. Check it out.
Youtube probably have stats on viewer-happyness vs bitrate.

I would take a guess that a higher bitrate = longer loading times, and viewers care far more about an extra few second of buffering than they care about audio quality, especially when they don't have the original to compare to.

Apple's ethos for a long time have been "On our terms only", for almost everything they've built. Why would they treat Swift any differently?

Accelerating in a huge vacuum chamber seems pretty difficult to achieve, and wouldn't there be a huge shock to the vehicle as it hits a wall of dense air?

How much of a difference would a low pressure chamber make, I wonder? Maybe you could build the circular accelerator then a much longer exit pipe that runs up the side of a mountain. Although that sounds way, way easier said than done! But if your exit air pressure is roughly equal to your accelerator air pressure, then you don't need a fancy airlock system.

The tether they proposed also seems a bit too much of the wishful thinking like "we just need a bundle of carbon nanotubes 1km long!" Wouldn't an electromagnetic accelerator work better?
I always seem to upset a lot of people when I bring up my take/experience on this because they seem to find it (psychologically) threatening. Labels such as ADHD seem to have value for those who use them and want not further examine themselves or their situation.

I was diagnosed with ADHD as an adult and after a few years of psychotherapy (and trying medication) it's becoming clear to me that a lot of what people call adhd, people with adhd, ... is an external observation of an internal experience of emotional management issues with regards to anxiety and anger: impulsively responding to these emotions in a way that was learned during an earlier developmental stage, that now no longer leads to desirable outcomes (often hiding, running away, not getting externally angry when it is appropriate or desired). A lot of self-deceit and unworkable mental models seem to be involved. I hope I'm not projecting myself too much :).

This is a far bigger problem than wfh ever was. Everyone has their own thing to do and there is no incentive to work as a team. I saw it in several companies.

I remember better times, working in teams that actually worked like teams, together on solving the same problems, all day. I don't think it had anything to do with being in the same room. The trend towards "everyone has their own jira ticket to work on and the only thing anyone cares about is how fast they can complete that one thing, so working together with others is just a waste of time" started years before the pandemic. It will not be solved by going back to the office.
> There has been an interesting result recently, which was discussed here [0]. In an online game where participants had to forage for resources, people with attention deficits scored higher, because they preferred exploration to exploitation.

The “scored higher” part of this study is editorialization. The game was developed in a way that exploration produced a higher numeric result so they could measure something as part of the test. The game was an artificial experiment environment and it was designed to “reward” behavior associated with ADHD, so it would have been more surprising if the game did not result in higher scores for people with ADHD.

The layers of editorialization and hypothesizing built on studies like this remind me of the debate over “depressive realism”. Some researchers put out a study showing that people with depression more accurately interpreted something in some specific scenarios which were designed for the study. It was widely misinterpreted by the public and pop culture science writers as showing that depressed people see the world more accurately, and therefore they are an untapped reservoir for seeing the world as it really is. There’s a huge problem with this interpretation because depression produces a lot of cognitive distortions that make people think things are much worse than they really are, so they’re really only more “accurate” when you have them evaluate situations that are worse than they appear. Yet this nuance is lost in the pop culture debate and many people think “depressive realism” means depressed people have a secret advantage.

I think these ideas have become popular as the diagnostic criteria for ADHD and other conditions have widened to include large percentages of the population. In the past the diagnostic criteria for ADHD was such that it was estimated to have low single digit percentage prevalence in the population. Now we’re at a point where Adderall is the 14th most prescribed drug in America ( https://clincalc.com/DrugStats/Top300Drugs.aspx ).

A similar thing has happened with Autism Spectrum diagnoses, where the criteria were once so strict that it was very rare for someone to get a diagnosis. Now I’m hearing fellow parents casually mention that their young children got an Autism Spectrum diagnosis after simply visiting a medical professional (found on internet listings) and suggesting it. Meanwhile my family friends with a severe autistic child are increasingly frustrated that pop culture idea of autism has shifted so far into the population that people are seemingly forgetting that severe autism is actually very debilitating, much like severe ADHD.
