I'd forgotten to upgrade grep on my latest Macbook. In a large source code repo, looking for a fixed string with no wildcards: osx grep -r: real 2m37.786s user 2m27.034s sys 0m3.958s ggrep -r: real 0m12.842s user 0m5.7

If we take the percentage of wealthy people that become artists as the baseline inclination of human nature, then we conclude that 90% of non-wealthy people are discouraged from becoming artists. It'd be interesting to know how much of

They can get in on a company much earlier than if it took the time to IPO. This gives higher risk and higher (expected) reward.

Also, the fact that phone companies allow caller ID spoofing, even of well-known bank phone numbers, is extremely lame. And the fact that calling back means a looooong time on hold discourages people from doing it.

Being an unsecured creditor under US law is much better than the law of the jungle, where rug-pulls are just tough luck. Unsecured creditors are still ahead of stockholders in the event of a bankruptcy.

Probably wise: there are too many ways to do it, each with different behavior for ill-conditioned matrices. GLSL includes an inverse for fixed-sized (2,3,4) matrices, which can return NaNs for ill-conditioned inputs. But it's fine for

I ran out of JS stack, walking the dependency graph of a big computation. Dependency graphs can be very deep relative to their overall size. It was a big pain to rewrite with an explicit stack of to-be-visited nodes. TCO wouldn't have

Yes; the quality of autopilot greatly influences how much I use it. 5 years ago Tesla's was kind of nerve-wracking and I rarely used it. Now it's pretty good on highways but I don't use it on city streets. I probably will whe

That’s far too late. You have to say it, with authority, at the first sentence that doesn’t add to your understanding.

I'd like a physics analysis of how flat/hard a surface you need to roll a D65536, how long it would take to settle, and how good a microscope you'd need to read the top face. Is there, like, 99designs for physics questions? I

There is plenty of criticism of these companies on HN. Thoughtful criticism is usually upvoted. But much of it has no more substance than yelling "Booo!", which gets appropriately downvoted or flagged.

Most waste doesn't give off very much heat unless you get enough of it close together to get a chain reaction going. A lump of stuff radioactive enough to kill you in minutes barely produces enough heat to get warm. So you have to get

The cool thing about nuclear waste is that you can measure how radioactive it is with a handheld device. Very convenient compared to biohazard waste.

Public companies are limited in what data they can provide to potential buyers. In general, they can't provide any more than what's in their public statements. The SEC enforces this rule to ensure that all investors have access to

Yes, but I think it's reasonable to demand evidence that the mDAU numbers really do include only 5% bots. Laziness and wrong incentives could easily combine to let that percentage creep up over the years. It wouldn't be the first

A lot of it is in the glaciers of Antartica, which cover the whole continent with around 1900m of ice. They weren't created from seawater freezing, but from snow getting packed down. But the water will go into the ocean if they melt.

I can't imagine it. If you somehow started with such a world, a few people would decide to really focus on one thing and get better at it, and others would follow, and eventually you'd end up with labor specialization like we have

The collective belief that you own your home is a crucial part of its value. If you come home and find a bunch of people partying in your kitchen, you can tell them to leave, or call the police and they'll drag them out. That's al

If this were true, stars couldn't form from hydrogen clouds. The primordial universe had only hydrogen. Fusion in stars created neutrons and helium, but this only happened as a result of high temperatures and pressures caused by gravit

Doing the experiment with various materials is a way of testing the assumption that the gravitational field produced by an object is exactly proportional to its mass. It would be a huge discovery if there were deviations from the law. It is

Exchange rates affect inflation for imports, but not for domestic goods. So varying exchange rates by 5% might only change inflation by 1-2% (depending which inflation metric you use). Like many things in macroeconomics, the exchange rate &

The viral coefficient must be higher for sketches that can be imitated in a few lines. SNL really specialized in this. KITH had a few such (like the Crusher) but as you say, most defied summarization.
