The thing is, you can teach linear algebra as a gateway to engineering applications or as a gateway to abstract algebra. The second one will require a hell of a lot more conceptual baggage than the first one. It’s also what the book is geared towards.

It is also intended for people who know something about the trade; it isn’t “baby’s first book on maths”. (Why can you graduate high school, do something labelled “maths” for a decade, and still be below the “baby’s first” level, incapable of reading basically any professional text on the subject from the last century? I don’t know. It’s a failure of our society. And I don’t even insist on maths being taught—but if they don’t teach maths, at least they could have the decency to call their stupid two-hundred-year-old zombie something else.)

That conceptual baggage is not useless even in the applied context. For example, I know of no way to explain the Jordan normal form in 19th-century “columns or numbers” style preferred by texts targeted at programmers. (Not point at, not demonstrate, not handwave, explain—make it obvious and inevitable why such a thing must exist.) Or the singular value decomposition, to take a slightly simpler example. (Again, explain. You task, should you choose to accept it, is to see a pretty picture behind it.) And so on.

Again, you can certainly live without understanding any of that. (To some extent. You’ll have a much harder time understanding the motivation behind PageRank then, say. And ordinary differential equations, classical mechanics, or even just multivariable calculus will look much more mysterious than they actually are.) But in that case you need a different book and a different teacher.

Clearly there’s a difference between building a bridge and getting customers to use your free app, but the vast majority of Engineers aren’t working in big infrastructure projects. Even the ones who do are competing with everyone else who bids on the project.

And in software there are plenty of cases where the 2nd or 3rd place product gets tons of sales even if it’s strictly worse in every category. There are so many things that impact market success that are completely out of the hands of product or engineering.
The Viral Threat Almost No One Is Thinking About
Treated with care and 1000x the development time, budget etc.

Things are slow because we prefer ease of development for these extraordinarily large and complex projects we call video games.

I think the smart thing really is to work it all out at a high level and then target the slow, considered and expensive fixes to where they're really needed.

I'm not excusing obviously lazy development though, but I do think we need to remember how crazy the scope of newer games can be. Imagine showing MSFS2020 to someone from 10-15 years ago; much of the earth scanned in and available for you to fly over, of course there are perf hiccups.

I know people have jumped here to try to explain it to you as a comment, but I highly recommend a recent talk by Freya Holmer. It's a fun little exploration of a seemingly simply question about vectors that motivates the answer you asked. It also culminates with an introduction to Clifford Algebras, which you may or may not want to learn about after the talk.

It's the inner child of developers. They feel the need/urge to show the world they can do it better than existing bloated thing. And they show it, and people jump on the shiny new train. Rinse and repeat. The problem is, those that could really make a dent are not present in this space :P.
My somewhat similar project VocabSieve [1] is intended to make lookups and making Anki flashcards very easy. Among other things, you can import highlighted words from ereaders and make Anki cards out of them automatically. I used it for Russian for the entire development process, so you can be sure it works well for that.

I've gone to appointments with my wife and have had to repeat what she's told the doctor to have them even pay attention. Then ask, what's the protocol to handle this? because while they listened, they weren't reacting.

She had to ask me to go with her because they weren't helping. And finding another doctor to go to would have taken weeks/months.
The common advice to delete toxic people from your life applies to those online as well. I don't think of this as a FLOSS-centric problem.

IMO, Suckless is about providing the minimal feature set possible. If you patch in an extra feature, that is what you get and nothing else. You always end up with exactly what you need and nothing more.

Compare this to software where you only ever use a subset of the features yet still have to pay the cost of features you don't use.
That's absolutely right. Have 'no plan' and nothing to look forward to is very demoralizing.
I've seen this idea before, and someone did the math showing that while it would be possible it would take an exceptionally large amount of energy to keep the magnetic field running. Not impossible, but I recall it being equivalent to some significant fraction of the energy produced by all power plants on Earth or something like that. Have any advances been made to lower the energy needs for something like this?

If you step back and think of "politics" as "the science of human behaviour" then Manufacturing Consent: The Political Economy of the Mass Media (1988) is still a worthwhile read. *

It argues that the mass communication media of the U.S. "are effective and powerful ideological institutions that carry out a system-supportive propaganda function, by reliance on market forces, internalized assumptions, and self-censorship, and without overt coercion"

- https://en.wikipedia.org/wiki/Manufacturing_Consent

In short, TLDR, mass media (eg: The Economist) tends to take the path of most return (sales, eyeballs) for least effort.

AKA it's much cheaper to be lazy.

They don't have the resources to have experts in every technical domain that sit about and read as many newly released papers as they can in order to pick out the gold for you.

They (and many other such public media newsrooms) skim the press packs sent out by university media teams, by political party media teams, the feeds curated by Reuters, third party summary feeds of stock market news releases, etc.

On the big stories the larger papers can spare the time of gumshoe investigative reporters to dig into the heart of an event as best they can. Specialist public journals (such as, say, New Scientist) will background and go into more of the lesser stories specific to their domain (it's The New York Times of anglosphere science).

But a great deal of the news that you see is first order lazy reporting, it's ideally assembled by reshaping press releases of self serving sources with a few phones calls, but more often than not it is nothing more than entire blocks of PR material 'plagiarized' as written with nary a phone call to fact check the basics.

Product-level thinking isn't confined to PMs. In fact, a good engineer should be conversant on the most important aspects of the product they work on, and care about many of the same metrics.

Having a good product function in a company can be very impactful when it comes to scoping and prioritizing, validating ROI, understanding what success looks like, and ensuring that people take into account the real cost of the work they do.

Sometimes this means making sure that engineers aren't just building things they think are fun but pose no real ROI, or asking engineers for things they don't feel like doing, or -- the gravest of all crimes -- asking for status on in-flight progress, perhaps even in person. This is why these folks draw the ire of some of our less mature fellows.
Who knows. They were working on http2 6-7 years ago and it hasn't arrived. I was under the impression the primary dev stopped working on it and some people were able to get maintainer access for security updates but that's about it. Maybe some people re-started development but not sure and Fastify has an express compatibility layer so it's not compelling to me.

You should draw no conclusions about quality or how well a game will run at launch from a game by another studio.
You’d be surprised at how expensive it can be to manufacture, program, test, package, warehouse, sell, ship, and support small hardware projects like this.

It may seem overpriced when compared to collecting all of the pieces and putting them together for yourself, but the person trying to do this as a business has to make a big investment in up front purchasing as well as labor to get them all together and shipped out. It quickly reaches a point where doing it for an “undercutting” level price doesn’t justify the risk and effort.

Yeah, right.

I can run basically any game at 1080p with at least 60fps with my 1080ti, except this game.

What they did with the mesh shaders is basically the equivalent of releasing a raytracing-only game.

So now I have to wait until GPUs become affordable again, which might not happen for a couple of years still. Shame, as this was the game I was the most excited about this entire year.

And no, spending money to get the same (or worse) GPU which supports mesh shaders wouldn't be worth it.
TinyPilot founder here.

I understand the feedback about the price. When I created the original TinyPilot,[0] I wanted a low-priced alternative to the $600 KVM over IP options I was seeing, and now I sell my devices for $400-500/unit.

The thing that's tough about selling hardware is that it seems easy to produce a few units cheaply, but creating a sustainable business for it, the costs add up. You have to fulfill orders, provide support when there are delivery issues, provide support when the customer has trouble understanding how to connect to a device on their local network. And there's certification, stockpiling components so you don't run out of stock, managing inventory from many different vendors.

TinyPilot became profitable in 2023, but for the first 2.5 years, we were operating at a loss. [1]

Also, small correction: no KVM over IP vendor is really selling open hardware. The part that's open is the software. I haven't seen any vendors publish their hardware schematics. It's expensive to create PCBs, and it's not like open-source software where you can hope to get useful external contributions.

I hate how it’s heavily marketed as a “challenge” and a “learning opportunity” when it’s a clear attempt to crowdsource for-profit IP geolocation data. There’s nothing challenging about running around collecting data for free, neither is there much to be learned.

The “challenge” has been on for 7 days. The stats say there are 1,779,796 IPs collected by 221 participants. That means on average each of these participants had to submit 1,150 IP location pairs, per day. How is that even possible?

> Syntax rigour has almost nothing to do with correctness.

I see your point: has almost nothing correctness with rigour do to Syntax.

Syntax rigor has to do with correctness to the extent that "correctness" exists outside the mind of the creator. Einstein notation is a decent example: the rigor is inherent in the definition of the syntax, but to a novice, it is entirely under-specified and can't be said to be "correct" without its definition being incorporated already...which is the ultimate-parent-posts' point and I think the context in which the post-to-which-you're-replying needs to be taken.

And if you're going to argue "This is just wrong?" (I love the passive-aggressive '?'?) while ignoring the context of the discussion...QED.

Hawai'ians had a number of skilled trades, and a caste system where a working class served a ruling class. Taxes were levied by the higher classes, and were paid in an amount based on the unit of land that was worked via subsistence farming. Those taxes were paid in the form of material goods (textiles, livestock, agriculture, etc). The material goods were the medium of exchange used to pay back a debt.

Therefore, Hawai'i did have money, in the form of commodity money (objects having intrinsic value in addition to value as a method of payment), which is distinct from barter in that there are specific recognizable units of exchange (specific amounts of commodity money used to pay a specific amount of debt). Material goods were also used as money for trade between islands.

There are other ways to reach one's goals or dreams, but at least for GP's case it seems the "idolization" of Bill Gates and Microsoft has motivated them to work hard and improvement themselves to the point that they could eventually get hired by Microsoft.

Spy satellites reveal undiscovered Roman forts
(Fly customer for the past 12 months: small web app (three machines across two regions plus replicated Postgres across two regions, on a paid plan)). Fly has been extremely stable for us, with the sole exception of deploys: once a month or so, deploys from CI start failing for a couple of hours. That doesn’t result in any downtime (I have never experienced any downtime due to a failing machine on Fly), just that new code doesn’t end up on prod until it’s fixed. If it’s urgent I email support (highly competent), or wait it out.

I would describe myself as “extremely happy with the service, yet also annoyed by this aspect”. Fly allows me to manage my resources in a way that isn’t really possible elsewhere (from standard Python web apps in multi-hundred-mb containers to specialised Rust apps in < 10mb containers), and in a way that is (now) extremely simple to reason about, and the support has been excellent when I’ve needed it (they were very patient and understanding when I screwed up a region move and managed to somehow break my db leader beyond repair), but I’d like them to address this, because it’s a widespread issue. Given the evolution of their architecture, I suspect they will. But I’d also like them to talk about it more.

It's been my guess that parts of Amazon can be good if you have a great manager who somehow shields you sufficiently from corporate.

That aside, I speculate that job-hopping culture means many people don't have to care much about corporate culture. In 12 months, they've gotten a lot of Amazon TC, added Amazon to their resume, and are ready to hop to the next place, before they're likely to get stack-ranking culled, or metricsed in a way they actually have to care about, etc.
