This is beautiful, but it seems to be missing two pretty common cases:

1. Off-axis rectangles, which are common for things like fighting games

2. Efficient convex polygon to convex polygon collision (GJK being the most popular algorithm), which is sort of the “most general” 2d collision detection problem.

For anyone else still confused: CVS is an American retailer that typically issues receipts with additional advertising, bad low-value coupons with paragraphs of exclusions, on the bottom of a receipt. This makes a single-item purchase result in a receipt exceed 2m in length.

Which means when you burn the methane you made with that CO2, it is being released into the atmosphere. Or, you need CCS on the methane burner. In which case, you might as well just save that CO2 and reuse it.

A friend of mine (now deceased) robbed a bank once. His side of the story was that he walked into the bank (unarmed, by the way) and simply demanded money; they gave it to him and he walked out. He said he was astonished at how smoothly the whole thing went. Upon exiting the bank he just continued to walk away, turned a couple of corners, and was never caught. His take was about 80 dollars.

Later on, he got clean and sober and told his sponsor about the episode. Part of recovery is that you're supposed to be willing to make amends for the damage you've done. His sponsor thought about that one, and said, "You know what? I think we're going to let that one pass." Probably a good decision.
Agreed that it doesn't apply to microdosing, and single-blinding the scientists handling the data is valuable.

I don't think it's as important for the attending scientists, who are also going to have a pretty accurate guess. What's more important is that they have some training in 'trip sitting' and that the experimental environment be appropriately designed, DMT: the Spirit Molecule has a number of stories about how things go poorly when this aspect is neglected.
I see your point. But because it would be interoperable with the developers and not the end users, so it’s still no dice for Google. The QWERTY keyboard is a good example of interoperability with end users (but not of copyright itself). So the courts would not give weight to that aspect.

White collar crimes are often mildly/un punished in other countries too, but when cops can murder in cold blood a passer by, or a girl sleeping in her house, and get away with it with essentially a slap on their wrist, that can't but send the message that institutions aren't there to protect and serve common people, but rather to exploit them to benefit the lucky 1% in power.
The loss of trust in institutions is a clear sign that somewhere there is still people with a functioning brain. The problem is in the institutions, not in the people who don't trust them.
A gift (c. 1997?) from my parents of a "box" of Turbo Pascal is easily one of the most influential moments of my life. It was such a great programming environment and the docs (books!) were fantastic and quite accessible. I'm still chasing the dragon of the feeling of programming I had back then.
No, it’s not premature. Skipping sqrt operations in the inner loops, which collision detection often is, is a generally good idea because the sqrt operation isn’t cheap.

Yes fair enough. This is why every employee should get paid _stock/rsu/whatever_. The rewards of efficiency gains that Walmart, the enterprise makes, should be shared by the people who made it happen. But then again, not many people would prefer to take that risk and instead prefer to get paid a set hourly wage. Of course, it’s a matter of balance — how much guaranteed income vs. risky income does a person want?

I don’t know. That’s a really difficult problem to solve through legislation.

Ultimately though stocking shelves in 1968 Walmart is about as efficient as stocking shelves in 2020.

Regulatory capture, which is the broad umbrella I'd put that under, is a problem with any attempt at regulation, I agree.

We can imagine a better regime, which could say "if you attempt to cheat or skirt around on this, we're going to hammer you harder than if you just break the rules", but how to actually get it is pretty murky. Easy to aim for that, and land in a situation where shadowy individuals wield great and capricious power.

I think the process of taking notes and compressing information is very helpful for retention. Unfortunately I lost the ability to keep track of long ideas while writing - I am not a fast writer. I chose to record lectures instead and pay direct attention to what’s being said. Later I go over the recordings and transcribe everything. It helps a lot, but it also takes a lot more time.
I have to agree. It feels like punching below the belt. The only reason why you know that the smaller startups have failed is because the founder has humbly written up a writeup on what went wrong and lessons learned, in the hope that it'll help others. By including them, the article is functionally punishing them for being open about their mistakes.

Maybe for larger companies this is debatably okay, because there's diffusion of responsibility. But to call out a startup with one or two founders who have been shouldering the weight of the startup? Who wrote a post because they wanted to be helpful, and now they're being publicly shamed? Come on

It's a very basic intro. Polygon/polygon is brute force, O(N^2). There's no coarse filtering so that only nearby objects are checked. There's nothing that points out that concave objects are much harder to check efficiently than convex ones. Plus it's 2D only.

An intro is nice, but this is like writing about sorting and only showing bubble sort.

It's my understanding that oral availability is lower than IM, and that people who are deficient get 70,000 IU injections.

I'm entirely untrained, but my amateur evaluation of the situation leads me to take 50,000 IU orally once each week or two. I imagine that twice that amount would be fine, too.
Just this week:

- Momentus: $1.2B IPO (https://www.cnbc.com/2020/10/07/momentus-the-latest-space-st...)

- Segment: acquired for $3.2B (https://news.ycombinator.com/item?id=24735414)

- MessageBird: reached a $3B valuation (https://techcrunch.com/2020/10/08/messagebird-series-c/)

More generally:

- 15-20 YC companies are now worth $1B or more.

- 100ish YC companies are now worth $100M - $1B. A good number of those (and others currently worth less than that) are growing very rapidly and will likely reach unicorn status in the next year.

So it seems like one can reliably expect 2-3 unicorns to come out of each YC batch. Those 2-3 unicorns likely more than make up for the costs associated with running each batch (including all of the ~$150K investments). Seems quite good to me.

Admittedly, there hasn't yet been a Google/Amazon/Apple/Microsoft-scale company that has come out of YC yet. I think it's only a matter of time until that happens -- anecdotally it seems like at least a handful out of the recent batches could become massive home runs, as well as other more established companies like Stripe that seem to be growing quite well.

A few reasons that all connect to each other. The biggest, most foundational one is that spammers are highly sophisticated criminal organizations, and will constantly be trying to figure out how to leverage your product for spam.

If they are successful, it is extremely costly for you (primarily in terms of IP reputation, which is very difficult to maintain) and cheap for them.

If they are unsuccessful, well, they'll keep trying and stopping them continues to be costly for you and they only need to get lucky once every so often for it to be worthwhile for them to continue.

Exacerbating all this, it's extremely commoditized, so even fairly large customers aren't going to make you that much money, especially given all the hassles of maintaining it.

As for more modern games, Hollow Knight is a masterpiece. A SNES controller has _almost_ enough buttons, but I had to remap one control to the spacebar.
The < 2MB figure is with huge pages (2MB ones in this case) enabled. I used 16GB of shared_buffers. The measurement at the end shows how much of a difference in memory usage that makes: The page tables use 6.5MB per process without huge pages, 132KB with.

So sure, you can have shared buffers set so large that it's more than 2MB per process - but there is a fair bit of headroom to 2MB. So I don't think it's particularly misleading.

I think threads are the right call, and that we should move to threads at some point. Partially due to the overhead you mention, but more importantly because there's a lot of features that are much harder with separate processes. We have a fair bit of redundant code due to it: one version working with plain pointers, one with pointers differing between processes, do deal with dynamically allocated shared memory for things like parallel query.

How do you not get that this is the exact point? “Experts” in the US government and the “intelligence agencies” declared forcefully that it was true. You—-not an “expert” and not a member of “authoritative” US intelligence agency—-claiming that it was just “propagandistic patriotic fervor” would be “misinformation” stated “without evidence”. Stopping people from questioning the narrative is fundamentally against free speech and having a small group of people presume to be the final arbiters of truth with the power to suppress contrary speech is dystopian to the max. You want free speech when you agree with it and suppression when you disagree with it. That’s deeply unprincipled.
This story would be more convincing if revenues and profit margin for US firms were correlated with wages. But insofar as they’re not, then all you’re saying is “firms chose to spend less on labor because there was more of it thanks to globalization”.

Not compilers released by Borland/successors or Free Pascal. It is all native code.
It isn't that much of a stretch to believe that they kept most of the compiler in assembly. The language itself didn't change that much from Borland/Turbo Pascal 6.0/7.0 to Delphi iirc.

Also, there was a source code leak about a decade ago of Turbo Pascal 6.0 that showed the compiler was still 100% x86 assembly. Just found it via Yandex - it was pretty hard to find with Google. (I only looked at the directory listings of the source code filenames just now, at some sourceforge-like site.)

You should read an economics textbook, then come back and tell me again with a straight face that productivity doesn't affect wages. You don't seem to have an understanding of the issues, and your examples are so irrelevant as to be not even wrong.

Roughly, the way it "should" work is that if Company A and Company B are in the same industry, and Company A is more productive than Company B, free market forces cause Company A to pay more than Company B, thus improving their ability to compete for workers. Generalize this to an entire industry of competing companies, and then to an entire economy.

The only thing that matters is the serum level. Testing your blood levels is like closing the feedback loop. Levels too low? Increase dose. Too high? Back off.

Genetic testing isn’t necessary or even really helpful. Just get the basic serum levels tested and adjust accordingly. It really doesn’t have to be complicated.

The Vitamin D blood level range is clearly indicated on the blood test results. That’s why I suggested that people get the blood test.

Blood test shows too little Vitamin D? Supplement more. Blood test shows you’re approaching or exceeding the upper limit? Supplement less.

There’s nothing subjective about it.

> the current official RDA of vit D is about 4-5x TOO LOW and was based on bad data (or a misinterpretation of the data).

This claim, however, is unbounded. We can’t just go around telling people “more is better” and that the official recommendations are vaguely “too low” and expect people to just guess at the real range.
