For solar sail you don't want to absorb, you want to reflect.

When you absorb you only get half of the push (assuming reflective surface reflecting directly back at 100% efficiency vs absorbed heat that gets radiated omnidirectionally).
> No inflation is bad because the economy stops.

How much net inflation was there in Europe between the Napoleonic Wars and the start of WWI? Do you think "the economy stops" is a fair description of this time period?
Totally! Reminds me of Foundation by Isaac Asimov where scientists turn into the equivalent of priests in some cultures.
Having a very brief look at the world of the ultra rich through an acquaintance of a friend, Im pretty sure that "reputation" to those people means a very different thing than it does to us. The key thing to remember is that these people live a very luxurious lifestyle that they can fund without ever having to work a day in their lives, so funding stuff like that to them is pretty much entertainment.

I can see that about 3, not really about 1, and not at all about 2. Ideally, 2 wouldn't be necessary but I don't see how that approach makes things worse, in particular when the "middle-man" mentioned is accurately described as "unqualified". There isn't any reason the person's conduct (opinion-forming ability?) couldn't be discussed constructively in such an instance.

Personally, 3 is a complete non-starter and I'd just spend my efforts elsewhere.

MkLinux for early PowerMacs ran Linux on top of Mach.

OSF/1, the attempt at an industry standard next-gen Unix by what is now the Open Group, holders of the UNIX trademark, also ran on Mach. Only DEC shipped it, though. The filesystem is now FOSS but I don't think the rest of DEC's code was, sadly.

This 98% reflectivity refers to the total solar light, including infrared and ultraviolet light, because the purpose is to cool whatever is painted, despite being illuminated by the Sun.

With fluorescent paints, the energy of the emitted visible light is always less than the energy of the absorbed ultraviolet light. The difference is heat that warms the paint.

The paints discussed in the article also reflect the ultraviolet light. Moreover, they also emit infrared light in the frequency band where the air is transparent, and that infrared light leaves the Earth if the painted object is outdoors, which will be true for a building or for a car while it is used. By emitting more energy than it is absorbed from the solar light, the painted object is cooled (if it is outdoors).

1. we should gently force a recession. 2. reduction in money supply. 3. this can be achieved through higher interest rates. 4. there will be higher unemployment rates. 5. home prices will fall down and speculation will cool. 6. inflation should be capped as soon as possible.

I am sure America is on the job. For all it's shortcomings, noone had to starve due to bad economic policy in this country and not for decades. Having to file for bankruptcy and living less grand is not the same as starvation death level poverty. And this, btw..still exists in many countries around the world. In America(not speaking about other economies), we'll be fine. It will be weird ride for the next decade, but this isn't bad for America. If we were a corporation, we have sufficient moat.
I wish my teachers had given me better answers to this question. As a teen I was definitely motivated by practicalities. No one could answer when I was going to use matrix math in life. The answer, which is glaringly obvious now is in machine learning. I really wish I had done better in math in particular, enabling more advanced programming, machine learning, 3d modeling concepts, DSP programming, etc.

But also, things don't have to be practical to be worth learning. I just think some of the subjects I struggled with in retrospect had much better examples of when they'd be used, and a huge opportunity was missed.

Cheating is a bad decision to begin with. I’m not surprised that further bad decisions were quickly in pursuit.
I think people will in fact get nostalgic about titanium dioxide white. Actually any white. Looking at the progress, in 50 years every surface is going to be covered with ads.
This is, I think, the single biggest factor in the proliferation of cheating. Most cheaters are smart enough to do the math on how they should win at the sport, or is smart enough to hire someone who can do the math. In other words, cheaters are rational actors.

Allowing people back into the sport swings the EV math heavily in favor of cheating if the penalty isn't massive given that the chance of getting caught is so low (as long as you know what you're doing). The only way to make the EV of cheating negative is to make the sanction very, very bad. Losing all of your future earnings from the sport is a good way to do that.

I used to run Magic: the Gathering tournaments, and there was a tremendous amount of "minor" cheating - forgetting the rules when it benefits them, shuffling in suspicious ways, peeking at opponents decks, etc. Many competitive players even openly admitted to doing this. Even if a tournament official could call them on the cheating and disqualify them (which was frowned upon without hard evidence), they would likely not be suspended from sanctioned play at all unless the evidence was overwhelming. Several famous cheaters did it many times and got caught several times. Minor cheating was very common as a result.

So because iOS apps can't run on Android phones, Apple is a monopoly and should be forced to use USB-C? I'm very confused by what you're trying to say. If apps not running on other OSes is enough to count as lock-in, then every OS creates lock-in. I've bought many Windows apps over the years, but they don't run on my linux laptop, and vice-versa. Does that mean both linux and windows should be regulated as monopolies? I don't think so. What you call "lock-in" are just software incompatibilities. Or do you think Apple should be forced to write drivers for every Android phone out there, and sell and support their OS on those platforms?

> When there are major software vulnerabilities (like log4j), the whole industry usually swarms around it, and the alarm has high value.

You're leaving me with the impression that you think we should only patch major software vulnerabilities. This I would disagree with. Minor vulnerabilities can be used, especially in groups, to do things we don't anticipate. It's not just about a single vulnerability but about how an attacker can leverage multiple different vulnerabilities together.
Because if the hardware isn't available they can't deliver the car and recognize the revenue. They can wait, but if they're gonna remove it anyway it lets them make more cars with less costs in shorter time. Seems logical if it is indeed parity.

Java is one of the very few languages out there that is manageable and debuggable at the large scales you're talking about. The tooling around it is second to none, and because it is statically typed with a decent type system, you can refactor quite safely in general.

The reason why they decided to remove ultrasonics is that combining contradictory signals from cameras and ultrasonic is not straightforward. What should have the higher precedence? So they ultimately decided that cameras can do what ultrasonics can do, but even better.

Now I don't feel like a well-rounded adult, and I wish I spent more time when I was younger on music and humanities.
> His claims aren’t of a moral nature.

His claims are 100% Kremlin propaganda.

No one else was ever claiming the things he said, aside from Russia. The timing of it was especially egregious, as Ukraine made a *HUGE* advancement over the frontlines this past weekend.

Pro-russian propaganda coming in exactly as Russia's front line collapses? What? The timing and speech pattern here (ie: the Kremlin-style argument of "Khrushchev’s mistake") suggests _direct_ Russian influence.

No one else was saying things like that. No one speaks like that, not here in USA at least.

People are still rather short-sighted when it comes to what a computer can do.

So I'm not terribly surprised that he thought running the engine in another browser window would have been sufficient. He might have even had it open in "incognito mode". And since it's incognito, it can't be detected, right?
> anything that adds a branch to check dereference in release builds is an instant no-go

...which, as shown by Rust, is actually not true, and is very much a go in the vast majority of cases.

> what do you propose to do instead?

It's easier and more natural to access the optional in an unsafe way (through the -> operator) than access it in the safe way (through `value()`); this is a wrong default which should have been made the other way around.

Potentially unsafe behavior should be opt-in, instead of opt-out. Yes, it's important that you have the option to disable this check for performance-sensitive code. But the majority of the code is not performance-sensitive to this degree that an extra branch is going to make any difference whatsoever.

I think a lot of the time it is just too abstract to grasp. I think the first time in my life where I was really happy to have learned calculus for my own intrinsic benefit was a few weeks ago, when I set up Home Assistant in an effort to automatically minimize heat in my apartment. It wasn't enough to tell the shade to come down at a certain temperature, because the apartment would already be too hot. So instead I could take the derivative of the temperature of my apartment, allowing me to get out ahead of the worst part of the blast of sun. After all, if the temperature is increasing very quickly, we should act to stop it.

I've used a decent amount of calculus in my life, but that was the first time I had been actually happy to have learned it.

The whole process is fascinating. The author encodes some mental structures into a language, at its lowest level, a sequence of letters. The reader decodes the letters into their own mental structures - the whole author reader interaction is very fragile.

Enter the translator, he picks the original sequence of characters in the source language, translates them into a sequence of character in destination language so that the reader of that destination language can decode the characters into their personal mental structures. Amazing.

He looks like a toddler throwing a fit. That doesn't sound like someone who has humanities best interests at heart.
Why governments don't do monetary policy by fiscal means? Well, because the central bank is the authority on monetary matters, and the congress the authority on fiscal matters. They don't even usually agree on what direction to go. (Things are this way on every democracy.)

But that specific question, nobody would take money out of the economy by fiscal means, even if they could. You would need huge fiscal changes to have the same effect of a small monetary restriction. And you don't do huge fiscal changes, ever.
thats the understatement of the century but true. abdicating your responsibility for a discovery phase during an acquisition is tantamount to fraud in the United States, but when he started to drag his feet and publicly proclaim a "hold" on the twitter deal due to spam accounts, it likely started triggering investigation into securities fraud. Musk may have wound up in the frying pan, but he didnt exactly do much to turn down the heat.

The court of public opinion is a bully pulpit for the wealthy elite but only if its the public opinion you intend to sway. Elon was about to start taking swings at investors and board members, who arent generally moved by public bloviation or jingoist egocentrism.

Some OTB tournaments allow players to go to the bathroom with their phone, others allow audience in same room - so an accomplice (such as Hans' coach Maxim Dlugy - another admitted cheat) could relay moves via signal. I've seen suggestion on Hiraku's channel that current scanning for players for communication devices is sub-par, although Hans has offered to play naked to disprove that theory (some porno site is calling his bluff by offering him $1M to actually do it). Anal beads? I dunno ...

Magnus has estimated it would usually only take one or two computer corrections per game for himself to play perfectly, so we're not talking about every move, just at key points. Apparently even just an indication that there is some key/winning move at a given point, without indicating what it is, is enough for the player to stop and put in the time to find it.
So a half drunk Howell blurts a single move to half drunk Carlsen in a bullet game and this is cheating?

You'll better understand contemporary media and culture by being familiar with the foundations they're built upon. Much of modern media are either nods or homages to, or direct knockoffs of, classics. Creators weave allusions to other works in their own work all of the time, and you won't pick up on or appreciate them without familiarity with what they're alluding to.

> It works fine on the happy path, but if mysql goes down, you lose things.

Why do you have to lose things if the DB goes down? Agreed, untuned & unconfigured MySQL (and MongoDB) out-of-the-box can lose things due to bugs and design issues, but that is the case even when they are running. However, DBs, in general are made precisely for the purpose of safely storing things and not losing them.

OTOH, the number of Kafka setups I have seen that'd lose things when something goes down ... maybe this is not a guaranteed win for the Kafka side of arguments.

> Having a distributed, resilient queue has availability benefits.

High availability is not a function exclusive to Kafka. On the other hand, there's some functions that may come in handy to use in a queue that Kafka simply cannot provide, but DBs can. Off the top of my head: ACID, instant scalability (both up and down) of consumer groups, and the sheer flexibility (and power) that comes with a DB in general.

Overall, there's some merits to using a distributed log as a message queue, sure, but there are also merits to using a DB for that.
