Another weird thing 7-Zip can do: extract files really, really, really correctly.

Often I download some japanese games (not pirated stuff, I mean freeware indie games, often being fan-made, like a fan game of some anime or something), and windows Zip somehow extracts them wrong, sometimes files are missing, or the game runs but with corrupted textures and so on.

If I extract same games using 7-zip then they work fine.

If there are files that use non-latin characters then 7-zip is mandatory, windows just fails to extract those files properly.

We've heard the same argument for a good decade and a half now.

It's still 80% theoretical, 20% real. Meaning that 20% of the time it's fine and you get a decent enough result, but 80% of the time you're fighting the edges and yielding a sub-par user experience.

I mean, if we're at the point where VS Code is a "good IDE" and say XCode or Visual Studio isn't, we're in a very bad place where it seems like idealized visions or dogma conflict with reality.

Higher level abstractions and cross platform solutions make a lot of sense for certain things in certain situations, but it is a developer convenience that always yields a compromise for the user. That's when someone else comes in with user-first solution and eats your lunch.
It's actually a pretty common thing for big corporations: this decision was publicly taken by a government, so it couldn't end up unnoticed so easily, but this lack of morality is the standard way of doing. Take for example when big companies decide about the lives of third world countries within their board of directors, in private.

Not exactly. Just make it mask season and make everybody wear it. You don't know when you are contagious/infectious, and it might not be at the same time when you are feeling sick. So just make sure everyone wears it.
The Neato vacuums do a much better job in this respect IMHO. They figure out the space with lidar and use a rectangular pattern.

The right trade off between business and customer is a business lead’s call IMO, even though it has a lot of software technicality to the decision.

Giving the most fitting (absolutely not the best) service to the customer is the job of whoever owns the interest in the business. Would a customer rather pay more for the features you talk about? The features are either free and easy and there’s no cost to pass around, or the customer is ultimately paying for it. Most people working on a product are just the sideshow to the intersection between business interests and customers.
At some point it hits Joe the employee and he can’t wait 6 months to get paid because he lives paycheck to paycheck and will starve by then. Overall you are right until it comes to individuals. A dry wall supplier can close its doors for six months and their products will t go bad. Joe the employee can’t just not eat for six months. If we do this systematically we would arrive at UBI. We would also need to delay all tax collection and so forth.
Robot vacuums have been such a game changer for me. It's funny because functionally they are worse than a cordless sick or full-size vacuum in almost every way. However being able to turn it on before I head for work everyday makes a giant difference.

One thing I am skeptical of is robot vacuums that connect to the internet. Some of the higher end Roombas do that and I'm skeptical that it makes them more efficient. Wrote some more about it here:

The good news is that the Eufy's seem to work fine without any internet connectivity. I've got the Eufy RoboVac 11S and would highly recommend it. Unlike my previous Roomba, it doesn't speed up before bumping into things—it mostly avoids it. Also, it is significantly quieter.
Yeah, sure, because of the virus.

Hard Truths for New Software Developers
In general copyright doesn't cover designs for machine parts, except insofar as they have an expressive rather than functional character, in which case they can be copyrighted as sculptural works. But you can still make replacement parts that copy their functional aspects.

If you want a monopoly on copying a machine part, you need to apply for a patent, not a copyright. Among other differences, the patent only lasts 20 years, and doesn't exist automatically but must be granted explicitly after a long litigation process — the vast majority of machine parts are not patented.
Kurento looks pretty great. Here's a brief snippet from their 'Getting Started' guide which could be useful too:

"If your intended application consists of a complex setup with different kinds of sources and varied use cases, then Kurento is the best leverage you can use.

However, if you intend to solve a simpler use case, such as those of video conference applications, the OpenVidu project builds on top of Kurento to offer a simpler and easier to use solution that will save you time and development effort."

(edit: and here's a link to OpenVidu: https://openvidu.io/ )
But it's not "if (false)" that was originally written. It's the problem only when the language lawyers search for the "loopholes in the standard" to derive the meaning that is turning

if (make sure something bad is not going on) {
do_something
}

to the following:

"I clever compiler author devised a way to analyze do_something and I see that you the writer of the code managed to write do_something in a way that can be considered "undefined behavior" according to this standard I'm using, therefore I am "allowed" to also remove the "if (make sure something bad is not going on)" to... nothing! See how fast the resulting code now is!"

It's searching for the loopholes to do something directly against the intention of the writer of the code that people have problems with.

In that light I fully agree with Linus:

https://lkml.org/lkml/2018/6/5/769

"I've said this before, and I'll say it again: a standards paper is
just so much toilet paper when it conflicts with reality. It has
absolutely _zero_ relevance."

"There are competent people on standards bodies. But they aren't
_always_ competent, and the translation of intent to English isn't
always perfect either. So standards are not some kind of holy book
that has to be revered. Standards too need to be questioned."

The 4chan instance with Shia Lebouf was an amazing read.

After months of harassment over the He Will Not Divide Us art project Shia moved it to a livestreamed flagpole with nothing but the sky as the background. In under 48 hours they mapped various contrails to flight lanes, matched up star constellations at night using celestial navigation and correlated weather to pinpoint the flags location. Then they went and stole it.

Ignoring the childishness of it all, it was some impressive crowdsourced investigative work given nothing but an empty sky to work with.

> Which isn't to say it is 100% safe for other reasons. I'd say auto-immune reactions are the biggest risk (e.g. the body using the signature encoded to attack the body itself).

Out of curiousity, why couldn't potential auto-immune response be simulated on a computer up to a degree of confidence, if nothing? Would quantum computers drastically rid of current computing related handicaps wrt to simulating a large search space typical of such simulations? What role might yet the recent resurgence in deep-learning play for immediate future?
rms was all over this "undefined" stuff. Early gcc versions actually tried to launch the games Rogue or Nethack upon detecting #pragma directives.

Old IBM "theory of operation" books used the word "unpredictable" for this kind of thing. "unpredictable" should frighten programmers. It's worse than "random," because random results have a chance of being caught during unit or system test.

Wow. Sweden has profoundly misapplied the concept of privacy when it is no longer possible for a person to voluntarily yield privacy for a project they find interesting.
Actually, fatality is most likely not as high as it appears from (confirmed) cases compared to deaths.

A large fraction of cases may go unrecorded because people only have minor symptoms and don't get hospitalized. In places with more extensive testing, like South Korea, deaths make up < 1% of confirmed cases. And even there, it's assumed that not all of them have been recorded.
Smoking is also more common (to my knowledge) in Italy. That could have something to do with it.

Once the dust settles, the data and more so, political and populus consensus will be more pro good air quality than currently and the momentum will see much change. That's my prediction of how this will traction over the years ahead.

Certainly see airplane tickets become more expensive as the days of cheap subsidized (low fuel tax's/duty) flights are in the end of days. Airlines running on razor thin margins will not survive this and personally, that's a good thing given the that IMHO the overall impact is a false-economy upon the environment.

Though that will only see more investment into electric planes, which will have a fair chance with a fair market for such competition.

Interesting times ahead, kinda focusing on the positives over the loss of life that will drive such change.

Business travel is also something we should look to curtail. I expect there are a high number of business trips that could be replaced with virtual meetings if they needed to be (say, if there was a global pandemic restricting travel). In the US around 1/5 of domestic flights are for business purposes [0]. If you also include people who relocated for work, and are travelling to visit family, I expect it would be much higher.

I got a robo-vac, but ultimately stopped using it because of chairs and children.
I had to clean up in order to run it at all, and it would get stuck under the chairs and not be able to get out. (I guess exactly the wrong sizing.)

I mainly got it because my wife and I have a dust-mite allergy and cleaning the floor with water or HEPA vacuum can help.
We've replaced it with a much more expensive (and totally manual) hizero[1] wet vacuum, and it's great. Also, we have tile floors so wet always cleans better than a vacuum (and wet pads need to be cleaned/replaced way too often on a robo-vacuum).

Of course he realizes how that sounds, that's why he prepended "I hate myself for saying this" rather than just saying the cold facts un-prepended.
Good points, but still, it's not consistent to use that low-bandwidth channel for wrong messages.

Sure, say that don't hoard masks, but don't say that it doesn't work anyway. Say that it would only work if everyone would use them. (Because you don't know when you are contagious anyway, so saying only sick folks should wear them is again a bad message.)

Also, saying that everyone should wear them is consistent with don't hoard them. (After all, if doesn't help you if you have masks but don't distribute them to others to protect you and "your loved ones".)
So that's your DOM operation... You literally are just accessing the same memory over and over again and because of the super-pipelined nature of CPUs, the fetch itself ends up being pipelined.
You make a couple of assumptions and I am not sure they are correct.

1. JIT's ability to elide microbenchmarking code

This can be easily debunked using a combination of DOM instructions and taking note of how dramatically the ops/s count drops and then comparing that difference in ops/s against the same difference from another browser like Chrome. If both browsers report wildly different base numbers but similar ratios then there is no cheating for micro-benchmarking numbers.

2. Worth pointing out that the linked page runs on an eight year old version of the "benchmarkjs" package

I found a different site that reports similar numbers so either they are using the same old code or the numbers valid without regard for the old code. https://jsbench.me/

Great business model. Outsource the content creation to the peons but then implement draconian restrictions so you have to jump through hoops to make a positive contribution.

Anyway, the correction is, the book "Set Your Voice Free" is by Roger Love, not Robert Love as stated in the article. Helpful for anyone looking for it because Robert Love writes Linux books that contain very little information about improving your singing voice.

I don't understand why anyone would be suckered into creating value for a place like Medium when they are so obviously exploitative.

"The standard" is not compiling my program, the real compiler is doing that, and the authors of that specific implementation should do the right thing, in spite of the standard leaving something "undefined."

Correct. And it can define it as to not to be an adversary to the writer of the code.

I imagine that many implicit rackets are irrational, and many explicit ones are ultimately later deemed to be morally-objectionable. So in the case of the former, no one wants to disturb a stable component of profitability, even as there is a sense that the paradigm is suboptimal, archaic, or however else a schema may become irrational. The latter is the answer to your last two questions.
