Even 1300s sometimes make the best move. Sometimes the best move is really easy to see or even mandatory, like if you are in check and MUST take that checking piece. Sometimes the best move is only obvious if you can look 20 moves ahead. So

I always wondered about the claim that SKIP LOCKED is all that efficient. Surely there are lots of cases where this is a really suboptimal pattern. Simple example: if you have a mixture of very short jobs and longer duration jobs, then ther

Not having a clear advantage might be a good reason to not choose it for new products, but there are thousands of companies that chose VMware 20 years ago when it did have a clear advantage. You have to have a pretty good reason to invest

What about mechanical devices that simply wear out? Even electronic devices can fail due to circumstances controlled neither by you nor by the manufacturer, like lightning strikes introducing violent transients in the grid supply. Also, coo

It's always been ironic that a book about not caring what other people think needs to censor the word "fuck" in its very title.

Many useful things are simple. Not all of them exist yet.

If that were the case, most of the (academic) software world would still run on Matlab and Borland. Instead, Python has completely taken over that space even without salespeople to push it. Most of the open source CAD stuff is just Not That

Sure, but the amount of photons as a percentage of the background radiation drops as a function of the distance. It's not all that far away in cosmic distances when any signal from Earth is millions of times less powerful than the nois

Anywhere in the galaxy within the super narrow beam that the Arecibo antenna happened to cover at the time, at least.

I don't think this is true: the older the tech, the less hype it has and thus the less blog posts/example repos/etc will be available. In particular, a boring language without a strong open source culture (COBOL, say, or Orac

It probably wasn't even a conscious decision. It's easy to imagine a young parent on 2 hours of sleep operating on autopilot and remembering incorrectly that the URL was "wicked.com". Or perhaps they just lost a parent a

All of it should be well below the waterline, it's what keeps the ship upright against the heeling torque from the sails. The whole ship displaced "only" about 540 tonnes (including the ballast), which I think is fairly light

For most startups the difference between Rust and Ruby is not 10 servers vs 1000 but rather between using 0.1% of a CPU or 1% of a CPU. A single server running Rails will easily scale to hundreds of thousands of daily users. Most companies

When I click on the "what we do" link right on the top of the page there is a fairly comprehensive page describing their company. Sure it is relatively humdrum B2B product to support sales teams, but that is hardly a reason to acc

I was thinking more about "tossing a salad" type vibrations that get high enough to completely get all the particles airborne, possibly with some sort of mechanical structure above the mixture interfering with the mixing. If you j

Yes obviously. But the POSIX specification for a "text file" as above is that it contains characters, which an empty file by definition does not. So an empty file cannot be a text file if you read that specification strictly, and

Probably, so don't `set -o pipefail` in scripts that pipe into grep.
536.
by WJW 2y ago
Kind of a weird definition indeed. One edge case: the definition states the file must contain characters, so presumably zero length files are out. But then how could you have zero lines?

I agree with most points but would like to add one about "tunability". This article focuses mostly on correctness, which is of course important (and without which the whole system would be useless) but in itself is often not suffi

You could have at least three types of linear mixers: - One where some type of spoon goes back and forth. This would probably just be worse than a rotary mixer though. - One where the entire "basin" oscillates back and forth like
