It's often more expensive to create specialized training capabilities in house. Contractors have an advantage with both equipment and personnel costs.

A contractor can maintain their jets however they want as long as it's safe and they can meet their contract requirements. The contract maintainers can stay at their job as long as they want. The USN and USAF maintainers move every few years and have pretty good retirement benefits (which used to be better but are still better than what most private companies give), and have to get lots of additional training and all that needs to be paid for. A contractor is still supposed to follow all the safety regulations, but contractors seem to be able to generate sorties at rates that military units couldn't manage even with double the manpower.

Contractor pilots are paid strictly to fly. Naval aviators and USAF pilots are both subject to "up or out" policies, where officers that aren't promoted are told to leave. This means military pilots have to serve as staff officers to keep themselves promotable. During a staff tour they either quit flying or they fly less, which kind of wastes the money spent on training them. There are good reasons for requiring this (and some good arguments against it), but the bottom line is that contractors don't have to worry about it and can operate cheaper because they aren't wasting 20% of their personnel budget with a fighter pilot working behind a desk.
It sounds like it's just a way for the Navy to blow taxpayer money.

Look at how our government managed a virus. Now imagine WW3.
Intel's scalar pipelining does do an amazing job of keeping pipes busy. And, well-pipelined code can approximate SIMD performance. But, in practice to solidly get that kind of pipelining you need to pretty much write your scalar code as if you were emulating SIMD.

But, the point is that a 4-byte load instruction leaves 12 bytes of bandwidth on the table for many architectures -even with a perfect L1 cache hit.

I point it out because I usually get rebuttals that everything is memory bound (true) and that using the cache well is more important (true, but it turns out...).
Five Cognitive Biases in Data Science (and How to Avoid Them)
Man I do not believe this. The restaurant and bar industry cater to the reckless youth segment. Seeing "nothing bad happened" to people you know who are less risk-averse than you is enough to coax people back into herding into bars and restaurants. We herded for a century before anything happened and those are clear memories everyone has, too.

What is going to change is the world's attitude toward the Communist regime currently running China. I feel pretty confident in saying that that regime is slated for death, even as public officials and famous people act, in public, like they're willing to get back to normal.

This is where some of us have been for a long time. You cannot permit an intolerant, racist, minority persecuting, citizen murdering, dictatorial, totalitarian government armed to the teeth with the latest in biowarfare who is inclined to make aggressive noises towards everyone who is not like them and some who are (Taiwan) to exist, period.

I think COVID-19 finally brought that home to everyone who is not just outright anti-Western in their outlook.

People are going back to bars and restaurants and jobs, the stock market is going to go up, but the Communist regime in China is going down.

That's what the near future looks like.

> Argentina and Turkey’s currencies devalued relative to their trade-weighted baskets of currencies. The dollar was not a driver of their problems.

The dollar was certainly not a driver of their problem. They had chronic issues and a strong dollar pushed them over the edge.
You mean this country has moved closer to fascism? I agree.

It’s too bad most people do not possess a spirit of independence and would prefer comfortable amusements.
>The 2nd amendment does not give the citizenry the ability to overthrow the government, it prevents the government from restricting the right to bear arms because bearing arms is necessary for a free state.

Why is the right to bear arms necessary for a free state if not to give the citizenry the ability to overthrow the government? It's not as if indian raids or an invasion from Spain or Britain are causes for concern, nor does the second amendment make up for the lack of a standing army anymore. Overthrowing the government is the only thing left that it's good for, as far as a free state is concerned.

>If the government does not serve the people, the people have an a priori right to reform that government.

What other means of "reform" does the second amendment offer the people, than revolution by force of arms?

US Treasuries pay in dollars. Buying a Treasury is a bet that dollars will still be valuable in the future. Am I wrong to see the high value (low interest rate) of Treasuries as a consequence of the value of the dollar, not a cause? If people lose faith that the dollar will hold its value, the fact that the US government is willing to pay 1% interest in dollar loans will not help bolster confidence.
I should probably write a blog post about this or something.

My big criticism of Ok-Wrapping is that it hides complexity in a way that's at odds with the rest of the language. Rust's big benefit to me is that it surfaces complexity. It makes me deal with it right now, at the time I write code. Even though async munges the type of my function, it feels different because it's explicit and has to be done at the point that I conceive of the function.
It's quite interesting that Australia wants to let these go in favor of the F-35, rather than maintaining them in a reserve capacity. Letting the F-111 go in favor of the F/A-18 made a lot of sense because they were obsolescent and expensive to operate. In this case, I wonder if they might regret it if they ever face a period of increased military tensions.
For the first job, I agree that it's important and I don't even have a problem with it being a factor. What I do have a problem with is discriminating salary or hiring based on what school you went to 5+ years into your career, by which point it matters a lot less.

Stage0 doesn't have to look so gnarly, if you are not doing diffs but just updating directly. This web app I've been working on doesn't look so bad[^1]. Note that I made part of the library compile time and part of it is runtime just to eek out a bit more performance (which doesn't really matter, but hey, JS is expensive, right?).

On library which I was looking at recently which would make Stage0 even look a little cleaner is [Strudel](https://strudel.js.org/). If you did something like that with Stage0 it would look really clean and then you just have the update method in your class that you call on updates.

Yup.

The hweird logical-fallacy use of "begging the question" is a mistranslation.

It goes back to Aristotle, who talked about "τὸ ἐξ ἀρχῆς", meaning "asking for the first thing". That is: you're debating some proposition X, which in the rhetorical terminology of the time was called "the first thing" (imagine that you're holding an actual debate, and you start by saying: The question before us is whether X), and the logical fallacy is when, in the course of arguing for X, you assume (ask us to accept -- ask for) X, the "first thing".

So far, so good.

So after the age when Serious Thinking was done in Greek came the age when Serious Thinking was done in Latin. Aristotle's term was translated to "petitio principii". The first word means "assuming" in mediaeval Latin but "asking for" in classical Latin. The second word means "first thing", a rather literal translation of the Greek.

So far, still so good.

And then, some time in the 16th century, some genius decided to translate the term into English and (1) render "petitio" as "asking for" ("begging") rather than "assuming", and (2) render "principii" as "question" instead of "first thing". Presumably they did #1 because "asking for" is one meaning of "petitio", even though it's not the one that's relevant here. Presumably they did #2 because in a debate (which, again, was the original context for the term) "the question" means whatever proposition you're debating.

The result of which is the ridiculous term we have now. The common usage of the phrase to mean "raising the question" is a much better thing for "begging the question" to mean. Personally, I mostly avoid using the term at all because some people will think it means "raising the question" and think I'm weird and pedantic if I use it to mean "arguing in a circle", while other people will think it means "arguing in a circle" and think I'm ignorant if I use it to mean "raising the question". (So it's an example of what Fowler called a "skunked" term: https://en.wikipedia.org/wiki/Skunked_term.)
This is misleading, at least if you're looking at a single core.

A single core can have >100 instructions in flight, but most of them will be waiting for their operands to arrive. The theoretical maximum throughput is gated by the instruction decoders and execution units, and is an order of magnitude lower.
The big problem with this plan is that it would require giving up and letting a large number of Americans die, which is a political and social nonstarter given current expectations around life, death and healthcare. (Well, at least amongst the secular parts of America. Some of the more religious communities seem to still hold the view that it's futile and arrogant to think this is something we can fight, much to the anger and bemusement of secular society.)
> If computation can be abstracted from not just the brain but any substrate at all then it exists.

Existence is a tricky as a proposition, as Kant famously argued. Does the following make sense to you: the law of non-contradiction exists.

Computation has similar logical character as other rules of logic. In fact, intuitionism ensures a 1:1 correspondence between the two. So computation is not a "non-corporeal thing" any more than any other form of logic. If you take rules of logic to also be non-corporeal things, well then this "problem" you speak of was present in functionalism from the start, and yet it doesn't seem to trouble anyone.

Sure. That's a very big "if," and the most essential person in kernel dev has the ability to make that the default if he wants. There's a reason he hasn't.

(If your environment actually doesn't need to worry about executing malicious code and you want to make syscalls as fast as possible, try a unikernel or implementing your code in a kernel module. Or, depending on what you're doing, try kernel bypass to get to the devices you care about and use something like https://lwn.net/SubscriberLink/816298/4aed890ee2dbffff/ to pin your user code to certain cores and get the kernel completely out of the way. Having to transition out of user mode to access hardware instead of making plain function calls, having to change page tables between processes, etc. are all performance-killing mitigations of their own. http://www.csl.cornell.edu/~delimitrou/papers/2019.asplos.xc... found a 27x performance improvement by getting rid of the privilege boundary between userspace and kernelspace - if you really care about performance and really don't care about malicious code, why would you leave a 27x speedup on the table and worry about a small percentage improvement from these flags??)
It is certainly very possible to do that, and it almost always requires sharing new information that relates to the context of the discussion.

Yes, but if they are the same disease, then the asymptomatic/symptomatic fraction of cases must be the same over time[1]. So a bunch of people who had the disease asymptomatically weeks ago should have shown up in a spike of people with symptoms, and it didn't.

[1] Or if they weren't, that would be a BIG result and very surprising. It's absolutely not something you can assume to make an argument.
> Amazon isn't scheduling any deliveries for another month

You can still try. I ordered some ink (which wasn't deemed essential by Amazon sadly, but in my case, it wasn't that essential, it could wait a month) 3 days ago and I just got it today (I saw yesterday that it was updated for tuesday, but got it way earlier, most probably because of easter holidays). They clearly give priority to essential stuff because it was still longer than usual, but they doesn't seems to have a huge backlog of essentials stuff either.

The only unambiguously wrong position is that the system works well and isn't worth improving.
These topics are covered extensively in cookie-cutter interview prep materials like Hacking the Coding Interview. Every candidate is treating these things the same as leetcode trivia. There are whole YouTube channels devoted to how to rote memorize the path to answer open-ended system design questions like designing a fault tolerant Twitter feed, asynchronous video streaming, etc. The rote memorization even extends many layers deep into “nuanced” follow up questions that are supposed to distinguish mere rote memorization from real experience.

This is just every candidate, certainly at the senior level. It’s impossible to use these questions to discern anything. Even asking them to give these details about past real systems they designed you’re just getting the same 5-layer-deep inception rote memorization of everything they could be asked and every follow up contingency.
> The obvious, implicit motivation behind an article like this is to help other users make the same decision.

This is not obvious to me. Why do you assume the motivation is "to help other users make the same decision" and not "to help other users make the decision that's right for them"? I promise you that some people have sometimes written with that motivation in mind. If any denial is taken as proof of guilt, how do you tell those people apart?
Slightly off-topic, but does anyone know where I can find good sources of similar analysis for the eurozone? I feel like I know more about U.S. monetary policy by now than my own area's.
1) like the article states, infact these things are not disarmed at all. and yeah federal contracts... Who else was he contracting again currently and what's the purpose of the whole endeavour then (there's definitely more money there except for fleecing the air force...). I would understand allowing such a business when it was a direct front for CIA-CAS (which it very well might be), but just to extend the private contracting business to freaking jets seems borderline crazy

2) well, the company seems to offer the whole package (see the final sections about him storing 80000 HE-rounds for his two dozen hawks). And once the US hegemony over who runs military conflicts on this world goes the way of the dodo, well... I guess you might easily fend of someone like Kenia intervening in your nice cobalt business in congo with a dozen of NATO-grade fighters... And there is definitely a private sector available to secure your bases in a "friendly" third country.

So...you're upset to see space opera played straight in your space opera? Have you forgotten entirely about S1 of TNG, or just chosen to ignore it? DS9 is "not Roddenberry", too, what with its most universally acclaimed episode being about Sisko deliberately subverting his own principles and those of the Federation to suborn all manner of criminality, not excluding several murders, in order to deceive a neutral party into entering the war as a Federation ally. Is DS9 awful, too?

To be honest, I don't get the mockery angle at all. I mean, you're talking about a show whose first season not only has antimilitarism as a major through-line in the way Lorca's story plays out, but concludes with a war being ended by a couple of people having a conversation about why more fighting sucks for everyone, and implementing a clever technobabble-driven plan to bring about peace. There's a lot I don't love about Discovery - most of its second season, for a start - but come on, what could possibly be more Star Trek than that?

Show HN: Browse and hire talent impacted by recent layoffs
FWIW, I appreciate you sharing this perspective. I concur, more or less, with your position here after having interviewed many hundreds of people over my career. I've found internships were the best way to identify who was quality out of a class. It seemed of every 100 new grads I interacted with maybe 3 or 4 were skilled and engaged in learning more. But there are also some standouts and I really wish more companies did internships with larger cohorts and allowed their senior folks time to mentor. Some of my best experiences in my career were mentoring interns and I made some solid life-long relationships that way as well.

I've often posited among friends in the industry that it's partly due to apathy and mismatched expectations. College students go into CS because they expect a good paying job, not because of any specific aptitude or interest. CS isn't the study of software engineering, nor of the act of programming. They graduate, with no appreciable skill, and no real desire to learn, and can't find work. We can argue about fairness until we're blue in the face, but the reality of the situation is that motivated students who are actually interested in learning have vast free resources available to them to learn and free resources available to them to demonstrate their competence. Anyone not taking advantage of these resources is going to be subpar compared to others in the labor market.

Pretty much anyone who went to college in the last 20 years should have been able to anecdotally identify the stand-outs in their classes, and in general on the other side of the pipeline those are the only folks having an easy time getting hired. I dropped out of college, even though I was one of the stand-outs, because I wasn't learning anything I hadn't already taught myself. I've had less difficulty in my career than some of my former classmates I keep up with and my salary is multiples of theirs when they are employed, we're all the same age and they're technically more credentialed. It comes down to the fact that most people are just not very good at programming or at systems design. In fact, I'm not a good programmer, my skill-set is very much in the arena of systems design.

They did the same thing with a lot of classic fighter jets, including all of the century series and the F-4. (I imagine plenty of F-16s have been used as drones as well.)

It's reminiscent of the way you can buy spectacular used luxury cars for a song once they've got a certain amount of wear and miles on the odometer. Maintaining them and accounting for the future cost of repairs makes their value drop precipitously.
Hey HN,

I work on the talent side of AngelList. Over the past few months, we've witnessed the tough decisions many startups are facing with layoffs. As a result, thousands of highly motivated and talented individuals have suddenly found themselves in unfortunate situations.

To some degree it could be true, as we see that Covid 19 hasn’t been a racially blind phenomena [1]. In the US, not all communities are in the same boat, even during an international crisis.

Excuses.

The government has crazy levels of surveillance but they took the Chinese at their word and didn't check? I smell bullshit.

There were multiple people warning that China was suppressing their numbers and outright lying about what was happening, the government/administration not listening is 100% on them. I'm sure we will continue to see evidence that people inside the government (not the administration) were yelling about this but no one (in the administration) would listen.

This is 9/11 all over again except even more unexcusable. They had intel about the plane hijacking plan but due to too much information and mistakes in the data (name mismatch) they didn't put 2 and 2 together. This time they had the data and regular citizens were able to see what was happening and started warning us and all of that was ignored.
This is not true:
The CDC had a pandemic team, they were let go.

It's just not factually accurate. Hate who you want, but don't ascribe political malfaesance where there is none.

The politicization of this pandemic is a disease itself.

Culpability lies with China for covering it up and possibly with their practices at their biowarfare labs.

We should all eat fewer bats, too.
Would the Holocaust have been quite as terrible if every citizen (Jewish included) owned a gun, and it wasn’t just the bad guys backed by the government who were armed?

Also, to talk about how it’s hopeless to have a gun versus a drone — there aren’t enough drones, and Vietnam is a great counter-example for “tech always wins.”
