They're saying the naive implementation was more than 150 lines of C code (300-450 bytes), i.e. too big.

No, it is correct. The integral is with respect to x, and the ordinary/partial derivatives are with respect to t. Written out fully, the derivative computation is d/dt (x^t - 1)/ln(x) = d/dt [exp(ln(x)t) - 1]/ln(x)

I'm not quite sure whether you're asking for an explanation or whether you're simply making the observation that this is often omitted from the discussion. Either way I think it's an interesting point, so I'll elabo

Yes, for instance ...101010 (the pattern 10 repeated infinitely) isn't an integer. It's maybe easier to think of the argument as working on sequences: From a sequence (x_0, x_1, x_2, ...) with each x_n a binary digit (i.e. 0 or 1)

I don't quite understand your main concern, but it seems others did and have answered. To elaborate on why Cantor's argument doesn't go through for the integers: Assume you had a list of every integer. To begin with, you coul

This does not – according to what I can see from the code and comments – implement the case of algebraic extensions. As someone only really familiar with the implementation of the transcendental case[1], my understanding is that the algebra

Indeed. As someone who (in the past) struggled a lot with eating, fasting would not have been a solution - it was the entire problem! This is the first cookbook I've read that seems to get the effort level vaguely right for a meal you

To be fair to the author (and I know this is by no means obvious context coming into the video), his channel blew up shortly before this video. His previous audience consisted of people in the Super Mario 64 speedrun/challenge communit

I do my current work (embedded) on an architecture with the following properties: - 8-bit bytes - 16-bit aligned accesses to 32-bit types - 32-bit aligned accesses to 64-bit types. - Struct alignment depends on the size of the struct (32-bi

I work on a <500kB RAM embedded project currently (and similar constraints in previous ones), and I can pretty much mirror what you said. The current project is in the planning/early development phase, and it's like everybody f

Most people have no idea how to detect basic non-blatant cheats. Even simple low-FoV aimbots sneak past the vast majority of players. Good enough cheats are virtually undetectable by just human inspection. The few people you saw cheating we

Short version of the difference: Safety = This shouldn't cause harm. Security = This should be hard to hack.

It's worth noting that ISO 26262 is mostly concerned with preventing faults due to system failure, e.g. spurious hardware faults, hardware degradation over time, etc. As an example, it doesn't have much to say about preventing a c

Primarily a Windows user here (though not really by choice) and I guess I'll bite - what does it matter what people put on the Desktop? Are there any security implications of not keeping it tidy? The rest of your points I fully agree w

Honestly I'm usually very wary of additions to C, as one of its greatest strengths (to me) is how rather straightforward it is as a language in terms of conceptual simplicity. There just aren't that many big concepts to understand

Worth noting that the Devil's algorithm is not a sequence of turns you repeat over and over, but one that takes you through every possible cube state. You "abort" it partway through when you reach your desired state.

None of this is really worth obsessing over I think, but one point in favor of imperative is it tends to also be the tersest phrasing, which is convenient if you're also aiming for 50 characters max.

True, that's a good point and I pretty much agree with you entirely. I didn't really make a distinction between argument and anecdote. Basically I think it's being glossed over that there is a blatant up-front cost to testing

I think the article is interesting, but I think it glosses over the very real cost of working like this. As someone with a career in safety-critical software (aerospace, automotive), it just doesn't make sense to me that anyone else wo

A little reductive I would say? I would add at least: * Puzzle (The Witness, Baba is You, Antichamber, Manifold Garden, ...) * Survival/open-world (Minecraft, Terraria, Don't Starve, Subnautica, The Long Dark, ...) * Horror (Amnes

Is it really because game development is "decades behind", or just because games are among the few pieces of software still developed against hard performance constraints? Loosely-coupled composable components may be great for pro

I thought most game devs were into the paradigm of: check external libraries straight into your source control, update them never, and generally treat them on par with your own code. What is it that a package manager does that's partic

Makes sense actually. That's been an annoyance of mine as well. I suppose I never realized it's better on other platforms.

This isn't a complete analysis. From the same site, cast iron has a density of 6800-7800 kg/m³, whereas aluminium is around 2700 kg/m³: https://www.engineeringtoolbox.com/metal-alloys-densities-d_... . With sp
