This is language dependent. For learning Chinese, recognizing radicals (like waht represents water, and what represents tree) can go a long way in helping recall of both meaning and pronunciation. Then moving on to learning Korean, where Chinese characters make up ~25% of Korean words, recognizing the Chinese character, then recognizing the typical phonetic alterations to Chinese pronunciations, can go a long way in helping recall of both meaning and pronunciation.
That's clearly "hacker true". I wonder if it's "lawyer true" as well? It could very well not be.
You want there to be a language-standard way of saying “I’m a backend for a web server and I don’t want to cause an error 500 but instead I want to crash the whole process”? Seems pretty specific to me.

Panic means “something’s wrong, this error isn’t recoverable”. In most contexts, the best thing to do is crash in this case. In some specific cases, if you keep things well-isolated enough (making HTTP handlers stateless, etc) you can design a system where panic means “something’s wrong, this error isn’t recoverable, and inform the remote end as such by rendering a 500 error”, and everything works just fine.

You seem to want some sort of truly fatal way of conveying errors. Panic is not that. If it was, Rust would not have designed panic to be handleable. It would be called “crash”, not panic. Go is similar… go’s panic is not meant for typical error handling, but it’s not synonymous with “crash”, either. It’s meant for situations where you want the moral equivalent of a crash, but taking the form of whatever makes sense for your use case. A multiplexing web server that renders proper 500 errors on a panic is basically the premiere use case doe this.
How to Choose Colors for Data Visualizations
These days, I just assume I'm or will be rejected. I'm used to it. And I keep trying to hit things I might not be accepted and there have been quite a few instances when I get accepted to something I applied, I'm confused and had to look up the history (mostly email) to backtrack the sequence of events.

Life is much more fun, challenging, and the reward even more super fun when you accept that more than 90% of what I do will be rejected, or laughed and ridiculed at.

To be fair, this is not actually all that far off the truth. Do napkin math on how much storage you'd need to index say 25 billion documents, and you'll see it's not actually a lot. 25 billion bytes is 25 Gb. How many bytes do you need per document (for the index)? A kilobyte, maybe? If so that's 25 Tb. While certainly not something you can fit on a thumbdrive, it's hardly something you need a planetscale computer cluster to store.

You may need it for the IOPS of actually using it, but that's another thing entirely.

I'm not so sure. For very long haul flights, I see hydrogen making sense.

There are 2 things going for liquid hydrogen: the square-cube law and the rocket equation.

The square-cube law: the mass of the hydrogen in the tank goes up with the cube of the size, while the heat loss rate by the square of the size. Which means for bigger tanks, the refrigeration overhead goes down.

The rocket equation: the actual equation doesn't matter, but the idea is that you need fuel to carry the plane, then you need fuel to carry the fuel, than fuel to carry that one, etc. It all converges, but the lowest the density energy of the fuel, the more fuel you need.

Hydrogen has an energy density 3 times as high as kerosene, by mass. By volume, it's about 8 times lower. But mass matters more than volume.

A long range airplane, like the Dreamliner, starts with a lot of fuel at takeoff, about 45% of its total mass. If you replace that fuel with a fuel that's 3 times as energy dense, then you don't need only 3 times less fuel, but about 3.7 times less fuel. Which means the takeoff weight gets reduced by about a third. Which means you can reduce the structural weight of the airplane by a lot. Maybe not a third, but by maybe 20%.

The compounding benefits of having a fuel that's 3 times more energy dense are considerable. Will they be enough to overcome the need for cryogenic tanks and much larger volume of fuel? I don't know, I think it's a close call. But it doesn't sound absolutely crazy to me.

Depends on the type of organization, and especially for titles like enterprise architect. Most people I know with enterprise architect titles don't code. They're mostly at non tech companies like banks, telcos etc. Even the standard software architects at many non tech companies don't code, or at least don't code much.

It absolutely is. Modern language design should be discouraging getting an element by index; there are usually better alternatives e.g. iterating through a datastructure, or using combinators like zip to build the datastructure/view you need.

How have they ignored the nuance of the Keira Bell case?

> It does not question the lawfulness of the treatment or guidance itself

Nobody is saying it does. The nuance is in fact what people are talking about. Many advocates for the trans community argue that under-16s should be able to choose such treatments for themselves without parental consent/oversight. The other side argues that trans issues should not be treated any differently than anything else, where generally children have limited say in medical interventions applied to them and that the responsibility is ultimately the parents'.

There's one set of folk working on a btree, and another set of folk are now working on a RocksDB storage engine.

The original preference away from RocksDB was that it doesn't play well with deterministic simulation. Any code included into FDB needs to be able to be able to run with coroutines (strongly preferably stackless ones, though sqlite's btree has a stackful coroutine shimmed under it). RocksDB is definitely not written to support coroutines, and thus trying to use it anyway results in sacrificing developers' abilities to dig into failures.

Redwood has a couple design decisions that would make it a poor general purpose btree, but a great one for FoundationDB. But RocksDB will still have write and space amplification advantages.

That's the reason. In principle, Google distributes execution and data storage for its mission critical applications. And most of the time, they do a pretty good job of that.

But (especially with the hardware crunch in recent years brought about by various effects, including COVID and Bitcoin mining putting pressure on the market) their ability to build out new datacenter capacity has stalled, and as a result, things sometimes end up bunched up in suboptimal ways, and a high capacity data center can become a single point of failure even though it shouldn't be.

For those unfamiliar with Nick Lane - his books are really good reads even if you're not familiar with the subject matter. Easy to approach, witty, and wry.

I just finished 2005's "Power, Sex, Suicide: Mitochondria and the Meaning of Life", which sets the foundations for some of the thesis in this article while trying to identify just how mitochondria got wrapped up with eukaryotes.
The meanings of all the various words describing firearms has been, particularly in the last 100 years or so, fairly loose. There aren't really hard definitions for "assault rifle", "machine gun", "sub machine gun", "pistol", etc, and they're even frequently used interchangeably for some platforms. They mean different things to different people in various legal and social contexts as well, to spite what internet keyboard commandos will say.

In particular, even if you use the "internet keyboard commando" definitions, a real AK-47 is both an assault rifle and a machine gun.

> If I control how an asset is allocated due to some arbitrary event, it does not follow that I deserve whatever I've allotted to myself.

i take issue with the idea that an "arbitrary event" is the reason why such an allotment is considered undeserved. This isn't any different than a lottery winner being considered undeserving of their winnings.

If one traces far back enough, you could argue that the current western country's wealth is undeserved, because way far back, an "arbitrary event" (aka, conquest and dominion) gave them the kick-start that nobody else got.

I would instead argue that no event is arbitrary - the lottery winner chose to make their bet, the lobbyist deliberately attempt to influence the law to their favour, etc. If such actions are not considered illegal by the laws of society at the time, then it is fair game. The good thing about western society is that laws aren't set by a dictator, but instead can be changed via some sort of consensus procedure.

The only argument i hear that such wealth is undeserved is that "i couldn't have done the same, therefore it must be undeserved".
I'm certain that, if someone came up with a workable replacement for Excel, then it would have a market in academia. (Would it earn the creator promotions? I think clickbait-y titles are more likely, not less, to get promotions.) I base this largely on the success of TeX in the hard sciences, which, by and large, won't touch Word unless absolutely forced to do so. (At least, that's how it is in math.) This is rather ahistorical, since TeX actually predates Word, but I still believe it.

Brazil is mired in government corruption and scandal and has failed to become even a regional power.

Russia is a pariah with a shrinking population and no real economy outside of petrochemicals

India is a more hopeful version if Brazil but still enormously corrupt. It’s also in conflict with Pakistan and China.

China is more likely to be the next Japan than the next USA. Huge debt from infra spending + population that will halve by 2050 is not a great foundation. They sabre rattle but have never in their history had a blue water navy - the minimum to be a credible military power.

My money is on places like Nigeria, Colombia, Namibia, Botswana. Places with relatively good governance and a functioning economic foundation, that are free of distractions from serious regional conflict.

I've converted an earlier version to Firefox a couple of years ago, and afaik the process for Safari is similar, it only takes a few changes, replacing "chrome" with "browser" in the source code mainly.

But maintenance-wise, that's another story, it means submitting every new version to both stores, updating descriptions, screenshots etc, which takes a sizeable amount of time, and providing support for users, which is harder since I don't use Safari personally, which is why I focus on Chrome.
Sometimes it do be like that though.

I’m firmly in the laser camp here.

In college I bought an HP LaserJet 5. It was old then, well past EOL, but was fully functional and previous owners had added a network card, so Icould add it to my appartment’s network and we all shared it. It printed thousands of pages with no trouble at all.

Recently after starting to WFH I realized how much I like reading contracts or longer docs on actual paper, and how much the kids ask to print work out. I’ve never had an inkjet last more than a year. I found a Canon C743 online second hand, and it’s printed flawlessly and quickly for several years now. It was $175 down from $450, not much more than a high end ink jet. I scan a lot more than I print too, so the AIO is great.

Lasers have quick print times, even better in volume, much more serviceable, don’t dry out, ink lasts ages, etc. the biggest issue with inkjets is that you need to use them often or they dry out, and the cartridges don’t hold much either. To infrequent printers they’re effectively single-use.

Inkjets typically sell themselves on photo quality, but photos are far more economically printed at better quality and consistency at a CVS or Walgreens. Typically our local stores do same day printing of basic photos for very very little, far less than inkjet ink.
I sympathize greatly because I think over the short term it's going to be worse all around for artists. I think anything that gets chucked into the ML wood-chipper is going to get old fast.
What operator is used to modify the value doesn't matter, just the fact that you can do so. At the point where you use an assignable lvalue, the optimizer needs to know where that lvalue came from, which means that pointers need to be tracked like references.

My point is that because pointers act like both values and references, they are neither values nor references. This makes it impossible to soundly reason about them.

"Every molecule will activate a combination of receptors. To give a hypothetical example, vanillin may activate receptors 73, 115 and 299, the activation of the receptor combination 73, 115, 299 therefore signals to the brain that vanillin molecules are being encountered. This is known as the “combinatorial code” of olfaction: each type of odor molecule activates several receptors, and each receptor is activated by several types of odor molecules, resulting in a unique combination of activated receptors for each type of odor molecule."
