The author wrote this post in the context of hiring at a "hard technology startup". I interpret that as a place where engineers are expected to be able to do cutting edge computer science research (it's not a "well-established [role] to do specialized tasks"). It's not clear to me what sort of questions you would ask "in line with the role they're assuming" for this scenario.

One idea here is to give candidates an open problem in CS and ask them to solve it. Which is a nice idea, but one of the other things I learned through administering hundreds of interviews is that open-ended questions aren't great interview problems because they depend a lot on creativity/lateral thinking/insight, which highly benefits from being in a relaxed frame of mind. So these questions end up being a test of how relaxed the candidate is.

Stress creates tunnel vision, which is terrible for generating interesting research ideas but it's OK for solving these kind of leetcode problems. So checking for a very high level of programming aptitude, as a proxy for CS research ability, is an approach which is a bit more fair to candidates who are stressed out by interviews. (I also think it is a pretty decent proxy, because doing great CS research requires you to quickly & fluidly generate & evaluate algorithms / data structures which might solve your problem, which is a big part of what a great leetcoder does.)

If you're targeting a very high level of generic programming aptitude, it is arguably most fair to make use of a standard method of measuring it. Leetcode problems are the industry standard for measuring programming aptitude. People know to practice them a lot and they know what to expect. If you came up with your own unique way to measure programming aptitude, that would create an even greater burden on candidates to practice (they'd have to do a whole different sort of practice in order to succeed in your interview), and also create anxiety due to an unexpected interview format.

I think a lot of readers are overreacting because they didn't pay enough attention to this bit: "It's applicable if you're building an extraordinary team at a hard technology startup." The vast majority of companies in SV are not doing hard technology and don't need an extraordinary team. People should not feel inadequate if they aren't capable of improving the state of the art in technical areas of CS such as databases. This is ordinarily the domain of PhDs, and filtering for demonstrated algorithmic aptitude (as opposed to academic credentials) is actually a pretty egalitarian approach.
I wish you could give us a single example.
I feel like I have to throw OVH a bone here.

From running a service with 50-100k concurrently active connections on a single VPS on OVH that has shrugged off a lot of attempted DOS attacks over multiple years, I have the impression that OVH handles DOS attacks exceptionally well. Specifically I've never seen it drop (a lot) of legitimate traffic.

In comparison to OVH, Hetzner (which this game seems to be using), is utter garbage when it comes to responding to any kind of incident well, or at least predictably. Their responses range from doing absolutely nothing, to nullrouting you, to terminating your service. With OVH I at least know how they'll respond to various things and they're (with few exceptions) professional about it, even if I don't like it.

I'd say you get what you pay for, but OVH (when comparing dedicated servers) aren't much more expensive.

Very nice calculation. The results were that by filling up two half tanks as opposed to fully topping off one can get an extra 3.5 kms, albeit with a time penalty for going twice to the gas station. Hardly worh it as just making the round trip to the gas station would probably eat up those kms.
To this I would add the wear and tear on the car by having it run longer with a nearly empty tank, something which is not recommnded.

By that logic, if we fired everyone earning below $20/hr, then the average wage of workers would go up, but that doesn't necessarily mean workers as a whole would be better off under that deal. Yes, the company with unionized workers pays 11% higher wages. It also hires fewer workers.

By limiting employment to only workers earning that extra 11%, yes, those workers are doing well but overall employment is lower, there are deadweight losses to pay for the union fees, and that isn't necessarily a policy that can scale to the whole economy. This is why there are such problems with youth unemployment in nations with high unionization rates -- it's tougher to break into that labor market.
> The US wants IP laws so it can protect it's innovation.

Parent's point is that US wants IP laws mostly because it has a trove of extremely valuable IPs and is in the leading position far ahead of any other player.

The same way Disney wants strong copyright and trademark protection, with low labor protection, lax tax enforcement etc. They would have different demands and priorities if they were still scrapping existing IPs from the public domain.
Of course the CEO is in on it. He probably set it up in the first place. How did he not recognize his own COO on the call?! Even with the voice "digitally altered" (?) it should be trivial to recognize someone you work with every single day. And if the CEO had been in contact with the YouTube person before he also, at least, should have understood that this was not him.

If you search for the CEO's name on Google Images, you get a wall of photos with the exact same broad, fake smile. What a character. It's amazing what some people can get away with.

An intuitive understanding or the mathematical formulas is that they describe an oscillating radius, which results in the various shapes as you move along the angle in polar coordinates.
RFC8259 also says that it allows implementations to reject strings that contain the character 'm', or to reject objects containing array values.

> An implementation may set limits on the maximum depth of nesting. An implementation may set limits on the range and precision of numbers. An implementation may set limits on the length and character contents of strings.

But those are not good ideas, and neither is rejecting numbers that are explicitly allowed by the grammar, but happen to be bigger than 9007199254740992.

There also appears to be a contradiction between these directives:

> A JSON parser MUST accept all texts that conform to the JSON grammar.

> An implementation may set limits on the size of texts that it accepts. An implementation may set limits on the maximum depth of nesting. An implementation may set limits on the range and precision of numbers. An implementation may set limits on the length and character contents of strings.

Helpfully, the RFC itself specifies which one should win:

> The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.

The discussion of limiting number values glosses over a pretty big logical hole:

> This specification allows implementations to set limits on the range and precision of numbers accepted. Since software that implements IEEE 754 binary64 (double precision) numbers [IEEE754] is generally available and widely used, good interoperability can be achieved by implementations that expect no more precision or range than these provide, in the sense that implementations will approximate JSON numbers within the expected precision. A JSON number such as 1E400 or 3.141592653589793238462643383279 may indicate potential interoperability problems, since it suggests that the software that created it expects receiving software to have greater capabilities for numeric magnitude and precision than is widely available.

Of course, integer values of more than 54 bits are also generally available and widely used. A JSON number such as 36028797018963968 does not suggest that it expects receiving software to have any greater capability for numeric magnitude or precision than is widely available. The actual reason for the mention of integer value restrictions is not discussed, but it is mentioned earlier in the RFC:

> JSON's design goals were for it to be minimal, portable, textual, and a subset of JavaScript.

These goals were not achieved, but they are still corrupting the discussion of numeric values. This RFC is a dog's breakfast. Writing "arbitrary noncompliance will be allowed" makes a mockery of the idea of a standard, and according to its own terms, the document does not even allow the restrictions it claims to allow. This document doesn't do anything except attempt to legitimate any and all existing or future "JSON parsers". There is no JSON data which, according to the lowercased restriction allowances, can be guaranteed to be accepted by a "compliant" JSON parser.

So let's be clear. You're honing in on this block:

> "It's applicable if you're building an extraordinary team at a hard technology startup."

And you're accepting that a timed question about tic tac toe is enough to prove you're capable of being on an "extraordinary team" at a "hard technology startup"?

Really?
You say "top-tier" and "very best programs" attendees get the jobs. But plenty of students study at other schools under the impression they also have the same sort of chance.

The correct answer is 1.6% for the unvaccinated, and 0.005% for the vaccinated.

Among Democrat voters, 95% overestimate the hospitalization risk for the unvaccinated, 78% are more than 10x wrong, and 41% of them are 50x wrong.

Republican voters are better at estimating the risk, but they still skew heavily towards overestimating the risk, although a noticeable portion of them are underestimating it.

Max gets brought up in these discussions a lot, but honestly I think the no hire was a good decision from what I know. Homebrew was a triumph of product design more than technical prowess, I suspect Google might have hired him as a product manager. Max was by his own admission was not a great programmer[0] but interviewed solely for a software role. I don't have a CS degree either, but I wouldn't hire someone to work google scale software if they couldn't invert a binary tree.

Mining is an industry where goods are fungible and it's hard to be a pseudo-monopoly. That means you can't make the high markups of people like Apple (customers won't switch to iPhone to save a few bucks), or Facebook (your friends are there).

Therefore I suspect nobody will become a billionaire out of this lithium. Prices will always be close to extraction cost.

Yes, lots of technologies work like that. Solar panels. Deep learning in pretty much its modern form was invented decades ago, but had to wait for the hardware to get good enough to show results. Personal computing took decades to take off. Heavier than air travel spent centuries as a curiosity.

Tipping points are fundamental to the nature of reality. Technology improves through decades of little tweaks and incremental improvements, which can sometimes bring a technology to a point where it's optimal and suddenly dominates the landscape.

The main difference there is that the lenses in a VR headset make the focus plane be infinitely far away. The main thing that's bad for your eyes with monitors and TVs is focusing your eyes up close for hours and hours. If anything a VR headset would be better for your eyes than a regular monitor.
I think so too: the mice went from 27g to 38g (32g for control mice), so they gained a lot of weight on this diet. For a human that would be like going from normal weight to borderline obese in six months. But I wonder if the mice were still growing up during the study (they were 6 months old at the start), maybe they got merely overweight.

That describes how things work at American universities. The worst part is not even the pay but the idea that people doing PhD are students instead of professionals. (Some places even talk about postdoctoral students.)

Your experience can be very different in countries that see junior researchers as professionals. You get a solid middle-class salary, and while you earn less than your friends who went to the industry, your life is not qualitatively different from them. Some travel extensively during their PhD, while others have kids and buy a home.

The opportunity cost for doing a PhD is much lower in the latter system.
Interesting approach, although I think SQL Server could do this kind of stuff natively (i.e. partition based on something easily indexable). Since Microsoft own GitHub, they could give it a try and potentially not go broke on licensing fees like the rest of us would.

Consider the input as a big space of points, where each point is a possible input. These points aren't unrelated; speaking loosely, foo(3.000000000001) is usually more likely to behave like foo(3) than foo(4) is.

The different behaviors on this space of points are due to the control flow and mathematical expressions within the function. You could thus model the function's behavior as a partition of the input: the different sets of inputs that will behave "identically" WRT the control flow inside the function. You could probably formalize this with a suitable notion of continuity, but I haven't bothered.

Accordingly, testing corresponds to searching this space for problematic partitions. It's a bit like playing battleship: if you know a lot about the possible shapes of errors in this mathematical space, then you can choose a few small points that can totally prove their absence.

Even if you don't know the shapes though, by choosing your points carefully, you can rule out shapes that are "sufficiently large". This is the impetus behind boundary testing; you don't prove that errors don't exist, but you can prove that they are relatively "pointlike"; that there aren't arbitrarily wide swaths of the input space that all exhibit the same erroneous behavior. Since the input space is usually vastly multidimensional, there's usually pretty hard limits on how much you can actually reduce the set of possible "problem shapes," though.

A lot of in-practice software testing out there (I can only really speak about the work I've seen at Google) is statistical in nature: you run a huge amount of tee-d or saved production traffic through a service, and run a massive diff of the output, after painstakingly making your service deterministic. By doing this, you can show that a "typical" query is unlikely to cause a "catastrophic" failure.

You don't need precise specs to practice TDD. If you have idea of the code you need to write, you can write the test for it beforehand - no matter how often someone might change their mind about the app.

Doing so would actually make your life a lot easier when it's time to alter functionality, because now you have well tested and testable code. Code that is written to be tested is usually a lot easier to reason about, to change and extend.

If you do it in concise manner and test behavior rather than implementation, what you previously thought of overhead will actually speed you up.

Etruscans settled a lot of colonies in the southern part of the peninsula, down to Pompeii (which was founded by Etruscans and taken over by Samnites) and Melfi.
And they were ahead of all other local cultures by far, especially in the metallurgic technologies and writing.
They were not a single kingdom but a group of city-kingdoms.

So I can think of Rome more like a colony that took over the mother city-kingdom first, then the whole peninsula.

Moreover, the names of the first traditional kings of Rome are Etruscans too.
Do they? Anyone who believes in the peg could provide that liquidity.
