Numerical operations in a loop are often subject to aggressive optimisation by C compilers, which makes them tricky to use in benchmarks: are we measuring the intended loop, or has the work been optimised away? Often comparisons are made of "Blub vs C", where the C result is an order of magnitude smaller, and it's not clear if that's because C is fast or whether it's been optimised away.

Including an "optimised away" version lets us know when this has happened: the "non-cheating" benchmarks take much longer than the "cheating" ones, so we can assume they've not been optimised away.

I assume the author only went into detail about them because they're independently interesting, regardless of the main topic of the post.
First of all what do you see as "successful"?
> "That's too complicated"

> "I don't want to bore you with the details".

Response: "Try me."

Dig for the details and if the candidate can't provide them, then either someone else did the work, they used a library and don't actually understand it, or they made it up altogether. This is assuming, of course, that they did the work relatively recently (<5 years).

If they deflect by mentioning either IP agreements or NDA's, then remain on topic but discuss something else under the same umbrella. For example, if the candidate deflects a question concerning k-means clustering, then ask about k-nearest-neighbors. If they continue to deflect, that's a red flag.

I'm a pessimist when it comes to hiring, but there are a lot of imposters claiming undue credit in this industry.

I recommend finding the best bullshitter at your company and having that person interview the candidates with you. A good bullshitter can always spot another bullshitter.

Thinkpads are a nice fit for OpenBSD if they are not too recent.

Somehow, OpenBSD on a 2012 x220 has all the energy saving features, suspend abilities, media buttons actions, etc you could hope for in the base system, without a full desktop environment.

I find this simplicity quite relaxing compared to linux, where you would have to install either a full DE or a bunch of not-so-well-integrated softwares (acpid, tlp, powertop, ...) to have your machine just-working with a simple terms+browser+tilingwm setup.

On the other hand, browser performance is not as great, virtualization, docker, USB automount and wifi roaming aren't really there. It doesn't make a difference for me though.
Look at the graph of Chinese Urban population and Chinese GDP. These graphs are in lock-step. Now look at the graphs of fully developed countries and extrapolate. The rural population is the economic fuel. So long as its there there will not be an economic downturn. There may be slow downs and specific cases of mismanagement, but never a true negative growth rate recession. IMO anyone predicting any change in the Chinese status quo before the mid 2030's is full of it.

I did not know that before...thanks for sharing...

But the whole point is about a fair income distribution in a society...

If you think that as a Pharaoh, without contributing much to a society but could still get all the best things -- including the pyramids -- provided by the people in the country, by telling them that his ruling is god's will -- which does not seem to hold much truth in it...I just feel that this is not justifiable...

This is a similar thing happening in China right now -- with all the propaganda and censorship and limitation on what people could read and talk at their own will, and hence influence the way people think and reason...

If the pyramids were not built by slaves, then there were plenty of other magnificent monuments or grand palaces or great economic achievements that were the labor of masses of hard working coolies who never got what they really deserve...

>one less attack surface

Yes, but your Amazon attack surface just got bigger.
Not a native speaker either (though I've been fluent for decades) and I find the title horribly misleading as well. "Might have triggered" implies the disaster happened, or at least that it's not known whether a disaster happened.

"Would have triggered" implies neither the disaster nor the near-miss happened, so I think the most unambiguous phrasing would have been "could have triggered".

OTOH I've seen native speakers use headlines like "Why this works?" (which by my understanding of the language shouldn't have a question mark), so IDK.

Firebase is fantastic and that's because they built their toolset and UI before being acquired by Google.

They recently Google-ified their website but it's still less of a mess than Google cloud console (which feels like navigating a helicopter's dashboard).

First impressions matter and I think Firebase nailed it. The website presents the value clearly while also allowing you to get into the weeds if you need to. They ought to put their design team in charge of the rest of Google's cloud platform.
> You still have to transfer the same amount of information to the computer.

Different target languages to transfer the information to may result in somewhat uncorrelated defects, allowing finding defects through mutual comparison.

You can test a generator by writing a recognizer and vice versa.

Errors in formal proof of correctness are somewhat uncorrelated with errors made in tests and errors made in implementation. By doing all 3 you can diversify to reduce risk.
Could this problem have been (partly) avoided by going for an LCF-based prover such as HOL or Isabelle/HOL, rather than a system based on the Curry-Howard correspondence?

I can certainly see it's plausible Haskell can beat Rust in the mid-term future on high-level programming away from the bare metal. Less certain that it can beat Rust for system-level programming or low-level library programming, where people using the library don't want to link to a heavy runtime that includes a GC.

This is facilitated by the fact that in some airports, taxiways and runways are similar and sometimes even used interchangeably (!), i.e. a runway may be remarked as taxiway and vice versa. So it's not 'how can he be so dumb' moment, in some case you have no way to tell the difference unless you just know.
Yes, but the aviation disaster didn't happen.

Might have triggered: SFO near miss happened, either it's unknown whether the aviation disaster happened (but there are suspicions it did), or it's unknown whether the two events were related (but there are suspicions they are).

Would have triggered: SFO near miss did not happen, but if it had happened, it would have triggered the aviation disaster.

Could have triggered: SFO near miss did happen, but there was no aviation disaster, though there could easily have been one if it hadn't been actively averted.

I work as a consultant software engineer, so my anecdotal evidence here has to be taken with more than a grain of salt as it approaches a reasonable sample size. I have worked in a LOT of different environments.

On the frequent occasions that I do work with female engineers, I have noticed that things mostly go one of two ways:
1.) she is acutely aware that she's an engineer in a "male" profession, and will either act with extreme imposter syndrome constant self doubt, or go to the other extreme to the point that it becomes noticeable and odd
2.) just be an engineer, seemingly unaware of her gender

What is strange is that I have met some absolutely fantastic female engineers who fall squarely into camp #2, and if you were to ask them how many grievances they've faced because of their gender, they would probably be nuisanced that you're even asking about it. They act like engineers and they get treated like engineers. If you were to ask the female engineers who fall into camp #1, they would have a completely different story. They'd be likely to say that they can never get a word in, or people walk right over them, people review their code more harshly. In my observations, the biggest hurdle is an internal struggle for a female engineer to see herself as an engineer, because people will see treat you like an imposter if it's clear that you see yourself as one. The more female engineers there are, the less they will feel like imposters, and the less they will be treated like them.

In other fields, I imagine things aren't exactly comparable, but I do think it's absolutely ludicrous for you to say that "every single day people make jokes about you sleeping your way to the top." This is not reality. If someone said that once, or that is some guy's "go to joke," it's obviously in poor taste and not funny, but this is not something that women experience every single day in the workplace. At this point, I've worked with more women than men (engineers excluded), under more women CEOs than male. I'm in the offices...these conversations are not happening "every day." For the most part, I would say that most of the places I've worked at largely feel like the women run the show, to be honest. That kind of shit does not fly anywhere outside of some very odd working environment unlike anything I've ever encountered.

Another comment mentioned green vs white. Even though it's practically impossible to get an aviation license with deuteranopia that just seems like it's asking for trouble. White light is rarely pure white and depending on the weather conditions I have a hard time believing the contrast is unambiguous.

Heck, maybe aviation should take a page from basic accessibility and figure out that information should be conveyed more than one way. Don't rely on color alone (and no, spacing of the rows of lights isn't unambiguous either, especially when looking at varying distances and angles).

It's not only a misnomer but the term is not needed. We've had SOA, web services, microservices, now serverless. I'm not saying it's all hype. It's rather a steady, lasting a few decades, transition towards outsourcing by encapsulating complexity into services. For me we've just arrived to the point where web services are mature enough so they can be consumed directly from the browser.

Definitely. Just compare eg git, mercurial, bazaar and darcs. They can do roughly the same things these days, but have very different opinions. (And that's just their CLI. The various GUI front-ends are yet another source of opinions.)

A lot of people don't seem to realize that being the top link on r/politics is a public good that's available to everyone. Just because someone pays $200 to make some politician's publicity stunt that nobody cares about be the top link there (I mean really, nobody cared - the idea of a law forcing politicians to walk around wearing the logos of their top ten donors is beyond silly), doesn't mean that everyone else can't also be the top link there at the same time, with other publicity stunts nobody cares about!

The great thing about being a top link is everyone can do it at the same time. It doesn't corrupt the process at all or waste anyone's time. Everyone can benefit from it and it doesn't make things worse for anyone.

For example imagine if all the top links on hacker news were just corporate advertisements disguised as stories. Would it be a worse place or cause any of us harm? Of course not.

Mmm. Here's the thing, I think we heard a lot of the same arguments before DSC took off for marine radio.

They too have uncontrolled radio, a large number of unknown people who need to communicate with whoever happens to be nearby, they have more powerful transmitters owned by governments that "need" to shout down less powerful ones on transport vessels occasionally.

Now, maritime radio IS a different environment. I'm not suggesting that DSC should just be dropped in as a replacement for AM analogue transceivers on planes, but I _am_ saying that I don't buy the theory that it so happens AM analogue is the right choice and not just the result of inertia.

For me, there are numerous advantages of git over svn:

1) git log uses a pager by default and is lightning fast compared to svn log which needs a server connection and is not paged

2) the "current commit id" is the same across all directories in a repo, while in svn every directory can be at a different revision

3) side benefit of #2, a "git status" in a subdirectory also shows the status of files in upper-level paths of the repo

4) backup-ability: every git checkout is a full clone, so if the server is down, or you're on the road without wifi, you can still work even with history

5) partial commits (git add/commit -p) is a godsend, I don't get why svn still hasn't implemented this

6) the tooling around hosting is way better - websvn is a laugh compared to gitweb and even more so compared to gitlab/bitbucket/github

7) support for branches
Before crying pilot error, we must all read Sydney Dekker's A Field Giude to Understading "Human Error" (and fully appreciate why he uses those quotes).

Assigning blame is a very human need, but assigning it to the most visible and accessible part is almost always wrong.
