One could argue that the key of virtualization is that a piece of software is run in an environment that pretends to be something else than the actual base system. A VM hypervisor runs an operating system in a way that it looks like as it is running alone on a physical machine, with some fake devices. From inside a container, similarly the environment is fake: it can't see processes outside the container, it's view of the file system or devices is modified, and it looks as if the things in the container were the only things on that kernel.
Interesting caveat to the computable reals. Equality is hard. I need to look into this but I'm pretty sure it's undecidable.

Edit: looking into it was just reading futher on wikipedia. Even ordering is undecidable.
> False positives are a lot more damaging to a company compared to false negatives.

People say this, and then they whine about how they can't find good candidates, can't find diverse candidates, etc.

They could, of course, study interviewing, treat it with the same level of seriousness you might apply to other skills, and actually learn how to evaluate people with a pretty good level of accuracy so you can avoid both problems.
The United States government decided that they wanted to escalate the war in Vietnam. For public relations reasons, they manufactured an incident and used it as an excuse.

Somewhere between 1.5 million and 3.5 million people died. The United States got Vietnamese, Cambodian and Laotian restaurants, and also 60,000 dead soldiers and 300,000 wounded soldiers.
NeXTSTEP, by the way, was a proprietary OS based on the MIT licensed Mach and BSD code.
That was a great movie and the scene was fantastic but none of the tactics OP mentioned were used there.
The article is unclear - but I think you've got the wrong end of the stick. The subhead in the Economist article doesn't say anything about drones either.
That is not a "raid". Complete shitpost.
That's not really the problem though, but that irrational people have power. Like voting or spreading fake information.

Also, I'd say people turn rational or irrational on their own choices.
Except they are not threatening to fly a drone into a plane.
The fact that it's owned by a private company is irrelevant to it's importance. Furthermore, "national" in this context doesn't mean "owned by the government", it means "domestic".
I think being a musician and programmer both require practice. As a musician, I would practice a lot of mechanics - producing the desired sound in a specific way every time. When practicing programming, I personally (and suspect most) would practice certain elements of mental recall.
In some cases that would translate into a mechanical memory (vim and tmux key-strokes in particular for me). But I sometimes also force myself to not use IDE shortcuts (or copy-paste) when I am trying to learn a new library or other programming paradigm. For example, I thought learning how to do "Pandas Python" after being fairly proficient in normal Python (and general programming) was hard in making that mental model shift. But I would learn ("practice") by forcing myself to type things that I could have copy-pasted.
I think the key is to be aware of what you personally require to become proficient at something. My programming practice methods might not work for everyone, and I know a lot of people who seem to instinctively "get" a new programming process. As you say "I think expert programmers just... produce programs" - this is the best place to be in! You are subconsciously "practicing" but it is wrapped up in your daily life that whatever worked to become an expert has become a habit and is no longer the burden of "practice."
> Also, let’s be frank, Lee Kuan Yew would have preferred to be PM of an undivided Malaysia than a city-state.

He would've certainly preferred to, but certainly had no capability to become one, nor capacity to act as one if he would've ever been elected as one.

It is said he had hard time not showing his jubilation when he heard of Malays effectively giving him his own state on a golden platter, and an opportunity to write his name into history books — more than what a man like him could've ever dreamt of.
Is the problem that leetcode questions were used or that coding was a hard requirement for a devops position? I do screeners for my team and being able to write code is a hard requirement for us. If you can't reason through and write the equivalent of fizz-buzz it's a problem.
Well looks like they got them in the end, but there is no way to extract them to USA.

Yep. "My tolerance for ZFS is pretty non-existant." Why do we let emotional children like these have their petty tyrannies?
Incompetence is the simple answer.
You can run the tractors on ethanol also, though?
It's not linux fundamentalism here - it backdates to Sun who released ZFS under a license that appears to be deliberately designed to make it incompatible with the GPL
Your logic makes no sense. We told Japan that we would drop a nuke on them. Does that mean it was all Japan's fault, and America created no risk?

I liked the part about how they never actually found a drone at Gatwick, but "experts" (?) say there "probably" was one.

I'm curious what they're basing that on, and who's considered an expert on phantom drones (as opposed to Phantom drones).
You're being obtuse. The aim of a bomb is to destroy lives and property. The aim of this protest is to stop planes flying, and to do so by flagging what they're going to do weeks in advance. Just the fact that they're talking about a mass of drones might be enough to close Heathrow for the day. The fuss about the recent drone-that-wasn't shows that you may not even need to fly them for this to have an effect, and if they do they're going to be damn well sure that they're nowhere near flight paths.
Yes, I am saying exactly that. This is a userspace implementation not making use of switch hardware fabric. You can probably hack hardware forwarding into it (haven't looked into this, our implementation predates it by 2 years). Or you can read an RSTP spec and implement it. None of it is secret, like none of CS in general is.

Both approaches however would be beyond the skills of a programmer who can't sort an array. And really it's not a high bar, I don't understand this obsession with anti-intellecualism. Everyone likes plumbing analogies, well I wouldn't trust a plumber who doesn't know that water generally tends to flow downwards - it's this level of CS knowledge we are talking about here.
I'd say that a system whose essence is to concentrate capital in a few hands, and where concentrated capital provides the power to tilt the system in your favor, is very prone to ending being fucked up. It's not that other political doesn't also suffer from this problem, but capitalism is not exempt from it.
So you’re trying to make a point by positing the most extreme scenarios of what these people could do instead of what they’ve clearly stated they will do-anticipated actions that don’t come close to being the same thing as bombing airplanes or destroying physical infrastructure?

Perhaps I missed reading statements where these people said they would fly an unmanned drone into a plane

I feel like there should be a term for this tactic of debate...
Truth: A Love Story
And war allows Congress to spend unlimited[1] funds, which, it seems to me, is a terrible moral hazard. I don't know what the answer is, but surely there's a way to stop war from crowding out more responsibly budgeted needs.

1. By policy. Obviously the money can still run out.
I think I've gradually developed something like deliberate practice as I go along, in that I increasingly approach greenfielding with an "idiomatic muscle memory solution" like "write approximately this style of loop", or "make approximately this data structure", and then start adjusting the outcome of that to fit the true nature of the problem, because that gets me through at least two iterations, while if I just sit at a blank page thinking, I produce code that is usually not really better and still needs adjustment. For some things architecture planning does help, but a great deal of it can be written as a pseudocode comment where i list the idioms i plan to use to address the problem. Often I do that, spot the flaws, and get in another iteration that way without having to go to the compiler. When I'm really stuck I go back to basic philosophy-of-truth reasoning and look for "a set of ideas that are coherent with each other" - one idea being the problem being solved, and the remainder being techniques to apply. Often this process reveals a need for research into unknowns, and hence another source of iterative feedback.

And so if I were to codify all the types of common idioms as if they were scales - which I haven't done - I would be able to drill those, but I suspect that there's a lot of them that are different between different domains of programming, and that's a major source of expertise.

Likewise my approach to naming has seen some iterative improvement, and it's definitely a thing I am training as I go. Names are like comments: you don't really want too many of them in your program, because they can obscure other information. Standardized variable names are great, and dense code is great when you can get it without sacrificing much readibility. I spent a little while evaluating what length of variable is sufficient to avoid collision and maintain readability while getting good density where needed:

1 letter - fine for local variables using detailed mathematics, where each variable is necessarily used in a dense, non-obvious way and it would be reasonable to have an explainer comment.

2 letters - hard to use well. As abbreviations they tend to collide too often to be recommended, and they are hard to recognize.

3 letters - a sweet spot for density and low collision rates, but still often unreadable.

4 letters - sufficient for most abbreviations and many full words.

5+ letters - at this point a majority of single words you would use will fit, and so you may as well consider this as "I am spelling out a whole word", with the next step up being multiple words and phrases, and at that point code density is the main tradeoff being made.

A common naming idiom I practice is labelling array-like values such as min/max bounds numerically, e.g. an axis-aligned box defined with x0, x1, y0, y1. For a while I used "result" as the variable for all returned values, after seeing this idiom in Pascal. Then I realized that I could use "ans" (answer) instead and get much denser code in a lot of instances. It's little things like that, which add up to a pleasant, lower-friction experience.
What about searching for keywords? That's how youtube discovery worked before recommendations came about and it worked fine (still does).
This looks great. I've been waiting for a nice, hackable, cheap set of environmental sensors!

There's only one "improvement" I would like to see - an option to buy a cheaper version without a display attached. For my application I will not need any display, and it seems a shame to spend resources on one when it's only going to get destroyed by the elements :)
So if LHR decides to let airplanes fly anyway, they'll stop flying the drones?
Virtually everything is a dependency in JavaScript, whether you're using node.js or not. One need look no further than your citation of `open()` as the proof that the nodejs environment "has more stdlib stuff". If the operating environment can run in a context where file IO happens, a native file open function is about the most basic baseline there is. It's absolutely not a good look for "well, we have `open()`!" to be the poster child of the JS stdlib.

After `left-pad` and `flatmap-stream`, attempts to justify the state of affairs in the JS ecosystem are patent absurdities. They show starkly that the platform vendor needs to offer a reasonably-robust basic toolkit, and that cultures of "every function should be published as a library!" are a massive risk factor.

A good first-party standard library should be considered a security requirement for every application. Dependencies should be brought in with care and attention, not in a massive indiscriminate orgy of nested modules spraying every function into its independent own library and resulting in every node.js application requiring its own 500MB+ folder of libraries to even start.

Think it doesn't get worse? People are now using node.js to distribute "business cards". Arbitrary JavaScript execution on your local user account. Has science gone too far?! Someone at npmjs.com sure has by allowing this kind of thing. [0]

The technical world is crumbling. Who can fix it?

Could we define it as a one to many function that maps from 0/0 to the set of all Complex numbers?

If 0/0 = Q, then

0 = 0 × Q. So, we get to define this operation. If we treat 0 as an integer, then we could treat Q (a set) like a 1 x inf. matrix and we have scalar multiplication.

But

0 × Q = [0]' × Q

So 0 can be an infinite set of 0. This is cyclical, I know. This cyclical nature leads to an interesting effect if we also define integer division. Try this around 0 in Q.

We could also define the × as an inner (dot) product, or as a cross product.

This is fun!
Your point is a little out of place because this period isn't simply representative of long-term fluctuations in wealth and status

Point taken that the example in the article is a lower boundary and an outlier. I think my point still stands. There was a lot of variation in the quality of life of a city dweller.
Does "seems to have come up" mean he amended his statement after recovering from the fire damage to his lungs? I wasn't able to find any information on this.
Well it doesn't always work that way. I have a bunch of MIT licensed libraries that are very widely used and I'm 100% certain there are no commercial forks of it of any particular value. Because then they'd not have my support when their stuff breaks. Im sure there's lots of other libraries like mine, the MIT license is not limiting anyone's access to the best versions of my code.
This is an interesting article and a lot of what was talked about is correct, this wasn't pushing any agenda, it's just the conclusion isn't quite accurate. The warming of the arctic does indeed push colder temperatures south, and there's an area int he north Atlantic that has seen drops in average temperature in recent years. This process may in fact have been part of how ice ages started in the past.

The incorrect conclusion that we are headed for an ice age that they came to was likely based on a lack of the information we have now. Namely the fact that the increase in temperature isn't just part of the regular cycle of heating and cooling, we're at the top of a heating trend, but the increase of greenhouse gasses is driving temperatures up more than a process like this will cool it down. There'll have been and likely will continue to be some colder winters in the northern hemisphere for a bit as the process starts to kick in, but the overall temperature trend is still getting warmer and isn't going to stop for something like this.

Here's an interesting map to see average temperature change in different regions.

The phrasing of your first paragraph confuses me. “I can’t help but...” as if this sentiment were hard to justify. The US government is notorious for lying its way into wars, and the current administration is full of psychopaths who would love a justification to invade Iran.

It’s like finding a notorious serial killer standing over a body holding a knife who says, “a ghost did it.” “I can’t help but be skeptical about the ghost....”

It was painfully obvious bullshit in 2003 and we must not fall for it again. If we do, it’ll make the disaster of Iraq look like a fun little game.
The correct conclusion is that you must never use or look at software that you yourself didn't write.

Of course, then there's patents. You might want to avoid having any ideas at all.

It may be an awesome piece of javascript to admire and behold, but to the scientist that has decades of fortran and matlab programs he's collected over the years, it's a tall order to expect him to rewrite everything in Observable.
For those who are interested in the paper:

https://dl.acm.org/citation.cfm?id=3192369

"Ryū: fast float-to-string conversion", Ulf Adams 2018

"Section 5 reviews the existing literature. All of the early ap- proaches require arbitrary precision arithmetic in the general case. More recent developments work with xed precision arithmetic, which is faster, but can increase the complexity of the code. By contrast, Ryu ̄ is simple and fast."

Also interesting:

"We did not compare our implementation against the C standard library function printf, as its specification does not include the correctness criteria set forth by Steele and White [15], and, accordingly, neither the glibc nor the MacOS implementation does."
It's still an issue, requiring large infrastructure investments to build battery stations and the charging equipment. Compare this to gasoline and it's precursor mixtures which could be derived from coal, for which there already existed massive distribution infrastructure.

I think the author reads entirely too much into the supposed psychology of an IC powered vehicle instead of the much more simple explanation: path dependency.

You're looking at this the wrong way IMO. One should not give exercises and try to eliminate candidates, instead they should prepare a set of exercises so that at the end, if the candidate solves them correctly they can confidently say "this candidate knows X, Y and Z", so they should do a good job in our project.

In your case, at the end you've only figured out that your candidate knows how to sort an array, which even high-school students can do. You can confidently say that your candidate has a level somewhere between student and Donald Knuth, a pretty useless piece of information.

Is there any connection between sorting arrays and spanning trees? If I'm not mistaken, the latter involves graphs.
Eh? Lots of things are part of the national infrastructure - the power grid (private), other utilities (private), energy generation plants (private).

Used to work on the same industrial park as a critical part of the national grid. Boy racers near there learned very quickly that you'll have a gun pointed at you for being there, and that's in the UK.

Um, yes, this is a nominally capitalist nation.

In a socialized or communist nation, you would expect all national infrastructure, if not all means of production, to be nationalized, i.e., owned & run by the govt.

In a capitalist society, not only the means of production but many critical national infrastructure structures and services can be owned and run privately.

E.g., power & telecom companies are regulated monopolies. Some roads have been privatized so the company builds & maintains them, utilizing some of the toll money. Lotteries are often private companies running state-sponsored games. In the US, there are private prison operators. Many hospitals in US are private. And of course many of the airports are similarly privately owned.

Obviously results and benefits vary widely by industry and operation.
The way I see it, 'int' as a truncation of 'integer' nicely symbolizes the way the type truncates integers to a fixed number of bits.

Of course any self-respecting modern language should also provide arbitrary-precision integers at least as an option.

All Reddit twitter and HN do is complain about data privacy and ads. It’s the complete opposite of ever being “they asked for it”. Can you find any big thread with more than a few small comments Resembling “they asked for it”? I can give you tons of examples for data privacy and anti ad stances. Just go to any FB thread. Or even this thread.
Well... I guess this is progress of a sort. But somehow it doesn't smell right. Bifurcating the science world by creating a whole new line of "open access journals" and while keeping the existing (and therefore more highly ranked and desirable) journals just the same, doesn't feel like the right solution. How about IEEE just embrace open access for it's existing journals?

I've said it before, and I'll say it again... I've been an on-again / off-again IEEE member for decades (off at the moment), but if I knew there was a body of people willing to work to form an "open access caucus" of some sort, aimed at radically transforming IEEE w/r/t Open Access, I'd sign up in a heart-beat. So far though, sadly, I haven't gotten any signs that there is much interest. :-(
I see a lot of comments about the governments responsibility.

There are two main ideas to approach.

1. It is in the govs interest to protect this private entity for tax rev and ability to anex it in war time. (we need some extra oil and a landing strip , this place looks good, your airport/farm is now the militarys till the war is over)

2. A private entity is protected by the gov no matter how big or small. As long as it doesnt break the law. This position is not about calculating current value of this one entity but of the general value of portection. This airport foesnt function not only are these tax/tourist revs lost but maybe others.

It ought to make it easier to divide them in war, and come to a swifter resolution in conflict.
You're of course right. I created that line for a different place, aiming for a provocative adage that would capture attention (by being aggresive) and make people think by getting straight to the point and highlighting the paradox of "pure freedom". For that purpose, being controversial and rough was a feature, even at the cost of causing initial rejection.

I copied it here to deliver the basic idea as fast as I could, but it certainly is out of context as the starter of a calm conversation with more time to expose ideas and ponder them, as is the style of this forum.
