I'm a huge fan of that book, but am very glad you called it out as more people should know about it. there's also a great companion book "Functional Differential Geometry".

My one caveat with that approach is it requires a very specific implementation of their library in MIT Scheme. There probably is a racket implementation by now, but it still looks like it's most small personal github projects.

The automatic differentiation landscape has changed considerably since that book was written. I would love to eventually be able to put together something like a guide to Lagrangian mechanics with JAX.
Interesting quote:

Amid the mounting signs of distress, a series of policies could help to minimize human suffering. However, most would require a considerable degree of international cooperation, which might be difficult to achieve in the current environment.

I'm really wondering if Orwell's prediction from almost a century ago, that the world would devolve into three major blocks continually at war with each other, each exercising authoritarian control over their domestic populations, isn't on the verge of becoming a reality. It appears that both Russian and American political leaders view the conflict in Ukraine as beneficial to their own domestic political interests, for example - and China is not yet involved, but what if there's a war in Asia, i.e. Taiwan? The global South sits outside this picture, so maybe there's some hope there.

As far as practical matters, there are a lot of approaches to ensuring local food supplies. Victory gardens were a thing in WWII for example. Also, there are several known vegetarian mixtures that give full amino acid profiles, such as the corn-beans-squash mix of pre-Colombian agriculture in NAmerica, or rice-bean bases of SAsia, etc. Recycling nutrients via effective composting also reduces the need for fertilizer imports.

Avoiding reliance on global supply chains is going to become very important if current trends continue, in any case.

Adam Smith warned of extreme division of labor making for humans dumber than the dumbest animal (paraphrasing).

Sticking with one career forever is an outdated story; king says someone is farmer, that’s just how it is! It would be costly to upend history, they say.

Having worked in a kitchen, built houses from foundation up, helped deliver livestock, started in tech designing power switching equipment, coding professional now since 2006; having built muscle memory for numerous “professions” comes along with living in “flow state.” I can manage structured tasks across contexts without planning, without wincing at the difficulty or time being a factor; I can make way better than packaged or fast food faster than it can be picked up or delivered.

Taking time to boot strap the habit pays off in time savings down the road.
There is one of these for sports scores too and it drives me crazy that there’s not an easy way to use it directly.

For instance, I like to keep up with my colleges sports teams, but I don’t need the live tracker stuff (if I wanted that I’d watch the game on tv). But I’d love to have a Home Screen button that would bring up the “app” for “Georgia Tech baseball score” or “Georgia Tech basketball score” to quickly see what’s going on what I’m in between meetings at work or out doing something with the family.

No ads, no frills, it’d be gloriously simple and I assume there is some way to do it but I could not find it.

Also possible with BTRFS. I set this up once for a small business with hourly snapshots during working hours. This way users could just restore older versions of files they accidentally deleted, overwrote or messed up in some other way.
Another benefit: Those snapshots were read-only, so they also served as a protection against ransomware.

Easily. I wouldn't put it past Putin to bus in the crowd from Russia just for this specific occasion. They've been doing it for years, why not again?

Just like they film Putin's meetups with "factory workers" or "wounded soldiers". If you follow the news for long enough, the faces of those "soldiers", "workers", and "miners" start repeating.

You have most of the mathematics needed to understand ML in one free book, Mathematics for Machine Learning [1].

It covers just about anything you need.

It would be better to study algebra, calculus, some trig and then statistics, it will give you a better knowledge, but this is a more condensed and a faster way to put you on track.

If you have time, you can go through it in one month.

Not really sure the comparison is valid. TrueNAS uses Samba to provide SMB network shares.
Closures are poor man's objects and objects are poor man's closures. Same with RAII and defer. You can pretty easily map code using one to code using the other. Is init/deinit/defer that conceptually different from RAII?
This "Zero-knowledge" style program, be it AlphaZero or MuZero and whatever, is a bad meme.

Adding in little bits of knowledge, such as liberties counting, ladder-reading, and other tricks, allows KataGo to absolutely crush LeelaZero in training speed and practical play in the game of Go. Its no comparison.

These days, no one studying the game of Go is seriously using LeelaZero anymore. Its an obsolete methodology compared to KataGo.

It's interesting to think that relays were an inherent part of all long range telegraphy (Morse's patent is 1840 and there were predecessors), but it took until the 1930s to start using relays to build electromechanical digital computers. The manufacturing technology would take a long time to catch up, but Boolean logic and electricity could have conceivably met a century earlier. (Edited 1940s to 1930s)

Total nonsense. It is not true of JS today, not has it ever been true.

No modern web app's or website's performance is dominated by the performance of what loops you choose. It isn't even remotely meaningfully impacted by that; by this I mean, any differences are totally unmeasurable beyond some 3 line micro-benchmark.

You have never benchmarked or profiled your code.

Of course, tight inner loops for image processing or ML, etc. yes, this can make a difference. But we're only talking about a handful of loops that matter out of many tens of thousands an application may have, you are almost certainly never writing those loops, and that's a specialized field that basically has nothing to do with the web. And it isn't what you're talking about.

> in this case, i'd prefer to be proven wrong with code, rather than prose.

What absurdity. And this is exactly when interviews suck. Because people have strongly held beliefs that are ungrounded in reality, and since there are no objective measures by which to rate interviews you need to pretend that they're real, because a lot of interviewers are basically just testing "cultural fit".

But hey! I have to say. That if you brought this up in an interview. I would at least know to never take the job!

That's a dubious statement. Filling the binocular field of view is fine; it's about 120° horizontally, give or take. But past that it starts to be a problem. Generally, if you look at the screen and any edge is blocked by your nose without turning your head, it's likely too large to work comfortably on. (but still fine for immersive content like games or movies)
It would be interesting to take this vector data and do some more sophisticated rendering on it. If this output EPS/SVG I would be tempted to load a few images into Illustrator and play around with assigning various brushes to the lines; replacing the naive line rendering with something that looks more like a slightly messy paintbrush that mostly fills the same space as a big fat EGA pixel could fix all the rendering errors you’ve noted, and look pretty.
That may be, but you're going to need an extremely compelling use case for people to go through with that.
I have both Quest models. They were fun for about a week and now they just collect dust. I've forgotten I own them.

Part of my problem with Quest is the "ick" factor of knowing that FB is looking over my shoulder whenever I turn the thing on. Giving up your privacy seems to be the price of just about every cool technology nowadays, and it means the tech has to be absolutely spectacular to make me pay that privacy price. My Tesla is sufficiently spectacular. Quest is not.

My first reaction was to be mildly bothered by the overwrought stereotypes on display. On second thought, having lived in rural America for most of my life, I can verify that this is about as accurate to life in rural America as most LARPs I've been in are to life in medieval Europe. That is: fantasy unencumbered by research. As in all things, I hope it's done out of curiosity and not with a sneer at people's misfortune, but fair play.
> I think there is a fundamental distinction between the professions of medicine and law, in that they have licensing boards that are a means of ensuring a standardized minimum amount of competency.

The summary: Licensing boards do a really poor job in maintaining quality. You can do extremely bad things as a doctor and still keep your license.
Very interesting, I had no idea there was a conflict between qm and chaotic dynamics.

Whenever “weirdness due to wave function collapse” comes up, I wonder: what is the multi-universe equivalent of this discussion?
Isn't Austin a city that is growing, continually attracting people? If so, it is not a valid example against their claim.

If you allow some pedantry:

The claim is that _cities that don't keep growing_ go broke: a->b

Showing ~b (Austin didn't go broke) only allows you to deduct ~a (Austin is growing) by modus tollens
The question is whether they are actually decreasing the number of false positives. So far I've not really seen evidence of this beyond some mere anecdotes. For such a bold claim, one would expect evidence to be readily available.

Which becomes even worse when realizing "false positive/true positive" is too binary of a definition for a spectrum such as job performance.

And I say this as someone who's in favor of giving people a quick check on whether they can actually do FizzBuzz.
my dad (american) visited germany to work on his german skills and watched "The Big Lebowski". He said the Germans in the movie were given russian accents.
There's no way that characterizes Austin. It's a sprawly city. Anyone who even tries to go car free there will be disappointed.
I don't think BTRFS supports NFSv4 ACLs yet (ie, Windows ACLs are natively supported on ZFS, there is patchset so Linux also supports it but BTRFS obviously has no integration for a patchset that only exists for ZFS).

Having NFSv4 ACL access is a huge plus since you can configure permissions natively from windows and have them enforced even on the shell.
I know about CephFS, but performance was abysmal compared to ZFS for a home server. On a single box with 4-8 drives I didn't come close to saturating a 10G link, which ZFS managed just fine.

It was also very complex to manage compare to ZFS, with many different layers to consider.

I'm sure it shines in a data center, for which it has been designed. But unless something radical has changed in the last year, it's not for a budget homelab NAS.
Your first sentence is already problematic. Do you have any data or research to back this up ? It doesn't seem very true to me.
Also a ton of important software was written as a giant mess of spaghetti code, or with horrible security vulnerabilities.

Texas may have a lot of f'd things about their laws, but one thing that they do very well is their "sunset commission". I think it's every 12 years or so, every department/licensure organization comes up for review, and they basically need to re-explain why they should exist. The idea is to prevent these organizations that turn into little fiefdoms to protect their own power.

A couple years ago the state veterinary board sued an Austin animal shelter leader and no-kill advocate and tried to have her license revoked. The sunset commission reamed them a new one, pointing out the absurdity of them going after a nonprofit leader while they had a major problem with vet drug abuse that they weren't handling. IIRC the majority of the vet board ended up resigning.

> It feels to me that the fight against cheating is basically fighting
against (kids) human nature.

Yes you're absolutely right. Wars on symptomatic abstractions like
"drugs", "terrorism" and "poverty" are always failures and become
ad-hominem, as wars on addicts, wars of terror, and wars against the
poor.

As surely as thieving loaves of bread is a response to starvation,
cheating is just another symptom - as you say, a naturally human
response - to an unjust and impossible circumstances. That doesn't
make it "right", but the context at least offers us some
understanding.

People will stop seeing "selfishly gaming the system" as acceptable
social behaviour once our systems resume serving the fullest interests
of the people instead of trying to control, manipulate and limit them
to the benefit of the few.
Berlin to Hamburg (~1:50) is a nice route. There's almost nothing in terms of population between these two cities.

However, every 2 hours there is a train that stops at Wittenberge (population 8k) and Ludwiglust (population 12k). I assume this is one of those mandated/political routes, rather than economic routes.

It adds an extra 20-30min to the trip, which isn't so bad. But whenever I've taken this route, maybe 2-5 people get on or off.

Would it be better served by more normal IC (200kph) or RE (160kph) train rather than an ICE? I don't know.
Their software and hardware are generally crappy, and I don't believe they can deliver anything innovate in a thousand years.

I've never been to high school or college. The last school grade I completed with 7th -- or really just 6th. I can go into that in more detail if you like but there's a lot of personal drama that is irrelevant.

I will say that math is one of those things that you don't need to go to school to learn if you are persistent and passionate enough to learn on your own. There are tons of ways to learn.

First is to determine where you are. For that I highly recommend taking some of Khan Academy's free math courses. They start at the very basics. You will get bored of those.

But after that... I would say to take some things in your life and determine how to apply math. Create your own questions and try to answer them.

When I was 26 I was at the tail end of a janitorial job. I had applied (and learned) math to determine how much cleaning stock would likely be in use each week. Sometimes the math was "wrong" in so much as cleaning stock would be used more frequently or less frequently depending on what events there were that week. But it was a good exercise.

I'd also been writing some software on the side. Software and math are like two peas in a pod. A lot of people will tell you that you don't need to learn math to write software and they might be right for certain kinds of software. But even if you don't need math for software, it will certainly help. I now write software to fly drones and geometry is one of the core requirements.

Beyond the basics are Khan Academy there are plenty (!) of youtube videos from mathematicians who describe some of the simple [0] and more complex [1] concepts. Those have also been handy to me. All you need to do is search one math term that involves what you think you want to learn. A lot of the videos will include links to other videos that are prerequisites. Almost all of them will mention math words that will be new to you and if you search for those math terms you are likely you find other useful information.

Ten years ago I would have recommended that you search Google. Now? Don't do that. Google is full of trash and shit that want to take your money. Use Wikipedia, youtube, and reddit.

I've found 3blue1brown's lessons [0] [1] to be quite insightful for myself and have successfully used knowledge learned from his videos.

I find this pretty interesting in that we still haven’t found a practical “raison d’etre” for VR, which makes the great and deal breaking parts completely different for each of us.

I see the future of VR as two-fold, with the use as a specific tool on one side, and games/entertainment on the other side.

On the tool side, I see hand tracking as 90% there, would use it mostly for navigation and input, and totally see myself in excel like applications with finger gestures and Minority Report like movements but actually well thought and useful.

I am with you one the game/entertainment side, where more feedback and immersion would tremendously help enjoy being in the moment and feeling things that aren’t there.
> "Do coding interviews work in the actual world in which we live in?" No, fundamentally not.

See, that's just not right. I mean, we all agree there's a hard problem to solve here, right? The world is populated by engineers of widely varying skill levels. It just is.

So how do you detect them? Well, the ability to bang out a correct solution on a whiteboard is a verifiably correct way to do that. It may not be optimal (passing candidates with other issues that make them bad fits), and it may have undesired failure modes (rejecting people who have trouble performing in the high pressure environment). And those are problems worth discussing.

But... it works. It clearly works. We've all seen it work. Companies that use these techniques aggressively tend strongly to be organizations with a long track record of producing working software. The FAANG employers are desirable because FAANGs ship code and make money!

So I just don't get the absolutism here. If there's a clearly better way that produces a more effective workforce, where's the darwinian example? Who's winning by hiring better people than Apple or Meta? I just don't see it.
> Then why require long time in school and residency for doctors? A boot camp should be enough.

Someone else answered the question: Nurses do not require a long time. In some (mnany?) states you can become a nurse with a 2 year associate's degree, and career outcome/pay is correlated with experience, not the degree.

And nurses aren't even at the end of the spectrum. You have LPNs, etc.

But the reason I commented: This notion that it takes so many years of school + residency is mostly a US/Canada thing. In many/most countries, you go to medical school right after high school - it is typically a 5 year program.
Won't be long now until IoT and other crap-ware devices catch on to this trend and start hard-coding DNS servers in code, or worse, using DNS encryption to avoid this sort of routine blocking by end-users. I wonder how people are thinking about solving this problem.
