Short version:

* Distribution of stellar velocities in elliptical galaxies implies DM

* Mass distribution in clusters of galaxies implies DM

* Gravitational Lensing observations imply DM

* CMS anisotropy power spectrum matches DM

* Structure formation in early universe appears to require DM

* Bullet cluster observations imply DM

* Flatness of the universe implies DM

plus some other statistical measures which also imply DM.
Not true of all of Europe. Irish salaries go as high as twice that for similar seniority.

Cost of living isn't lower, especially in Dublin, our healthcare system is a slightly worse, college isn't totally free (3k/year or so), and pensions less generous.

On balance though, you'd still be better off working here.
Time:

* Falling asleep /// Waking up at a fixed time, also during weekends. Not eating or drinking (other than water) atleast 4 hours before bed. No screens 1.5 hours before bed. Wool duvet (comfortable temperature range is much higher than down or synthetic, less sweat).

* Waking up /// Drink a glass of water, turn on daylights, do push-ups.

* Styling my hair. Going to a barber /// Trimmed it to 2mm and maintain it bi/tri-weekly.

* Shaving /// Grew a beard and trim it weekly.

* Washing clothing /// Replaced t-shirts, sweaters and socks with merino wool. Doesn't stink wearing it a few times, dries quickly, good for hot and cold weather. Underpants are synthetic because of increased moisture wicking and durability.

Money = time:

* Using shampoo and conditioner /// Use 'No Poo' method (also when I had very long hair).

* Using perfume /// I use deodorant (coconut oil based) to prevent smells.

Also: yall ever hear about that syndrome that originated in Stockholm? This site obviously needs a lot of work
Friend when she was in a poor part of Africa noted that the local cell tower had two armed guards. Her host told that a few years prior they had a single guard. Thieves came and killed him with a chainsaw and stole the generators. So now the guards are armed with machine guns and there are two of them.
It's futile to actually have road-legal cars that go this fast because you can't do very much useful with the speed.

This is much too fast for the human operator (driver) to safely react to things outside the cockpit, which is why for example Britain owns trains capable of 140mph in service but deliberately limits them to 125mph. Tests suggested drivers couldn't be relied on to reliably observe and react to a lineside signal (showing e.g. double amber, "Prepare to find the next signal at: Prepare to find the next signal at: Danger") passed at 140mph. The "obvious" upgrade is to put the signals inside the cab with the driver, and that's how high speed trains work. But a car doesn't have in-cab signals either, and it has a LOT more external signals to respond to, including several signs we see in that video.

That's not true for the modified Ford, though I concede it is for the Koenigsegg.

They don't have a record yet, but the record they are aiming for is for the fastest "production" car. The car they used was modified from stock so it doesn't count for the record yet. But this will almost certainly lead to a small batch of cars with the same configuration from the factory, which they will use to (re)claim the fastest production car crown.
Non-production car, not replicated in both directions. Impressive, but not any sort of record. Looking forward to them doing it in the forthcoming production car.
Do you have a source or link to any verified speed runs by those cars? AFAIK those are theoretical numbers, and Koenigsegg has never had a verified run at 300mph+)
The modified Ford GT already reached 300 mph: https://www.topgear.com/car-news/usa/ford-gt-just-did-300mph

It needs to balance low drag, down force, cooling, and probably a bunch of other factors. And it needs to look cool.
I don't doubt your interesting bit of trivia, but I couldn't find anything online about. Do you have a source for this? I would certainly love to read more about it.

Ask HN: Why is Google in love with purposely-impaired languages like Go, Dart?
Google seems to invest a lot in R&D for programming languages and tooling (probably only surpassed by Microsoft, and percentually by dev-tooling-focused companies like Jetbrains), yet nevertheless, all they seem to produce seems to be "mediocre by design" in a way, or at least designed to be restrictive and/or to impair developer flexibility and productivity.

On the languages side Go and Dart seem like the epitome of "Blub languages" in PG's essay lingo. Even modern Java seems flexible and featurefull in comparison with them. Compared to Go, Rust looks like Common Lisp looked like to a Java programmer of old. Compared to Dart, Kotlin and Swift look like Smalltalk probably looked to a 90's C++ programmer...

Where is this attitude coming from? Is Google's philosophy that most programmers, including their own, are either stupid and/or irresponsible and shouldn't be trusted with powerful tools that can increase their productivity when used right? I mean, software is their business, they're not churning ecommerce infrastructure CRUDhorrhea... they should be capable of leveraging powerful programming language features to massively increase developer productivity, right?

Just looking at unemployment statistics, it does not seem like there should be tougher job-competition from a market-based point of view.

Certainly not in STEM. But other college graduates aren't faring that much worse either. So if competition is a stress factor in this, then it can't be explained by market forces.
Alright, that makes sense, and I suppose the title doesn't claim they're the first to build a road-legal 300 mph car (as they're not).

This is why the TGV has no signals. Instead it uses a radio communication system. If no radio signal is received within a time frame, the train will warn the driver, and eventually stop. If a train has to perform an emergency stop, all other trains behind it are informed via the same system. If the driver does not react, the train will stop itself.

There is a reason why the TGV has seen no accidents since its launch in 1981.

As for a car, yeah, it's mostly a gimmick. Still incredible engineering, though.
I tend to be ridiculously un-careful with my specs except with how I clean them, my current glasses are regular plastic with no coatings and they haven't scratched yet. I wash them under warm water with dish detergent and my fingers and them hit them with compressed air or a micro fiber cloth to dry. I wonder how you are cleaning yours as my current pair are over a year old and I can't find a single scratch.

The only thing they need to be concerned with is being faster than everything else. Units are arbitrary, even kilometers (1000x the length of the path travelled by light in a vacuum in 1/299792458 of a second). Once they go past 500 km/h people will start wondering about some other round number until we get to relativistic speeds.
It's too bad that the state of roads in most countries is aweful and can't support anything approaching high speeds, let alone this insane 490 km/h.
The glass face of a watch is often called a crystal for reasons unclear to me.
British publication.

So relatively muscular imperial miles are correctly used. Readers' eyes might pass over in disinterest should weird & weedy "kilometres" be used instead.

On a more serious note, I'm sure the various manufacturer marketing departments take every opportunity, imperial, metric, Klingon, whatever, to mark a passing of a numeric "barrier" - i.e. a number ending in zeros.
A train going faster than 25mph or so is already too fast for the operator to react (braking distances are huge!), so I doubt that the top speed is limited for that reason.
> The "obvious" upgrade ...

What's stopping the trains from operating autonomously?
Fair point. I guess maybe it diverges at the point where need diverges?

All companies need managers of some sort, and at the size we're talking about all companies will need a hierarchy of managers. Not all companies need a "Distinguished Engineer".

I think this is still an aspect that can be done better. If the top level of management (before C-suite, not in reporting chain) is some sort of mentor status, I'm not a fan of the term but an "Agile coach", or some sort of expert like that, maybe that's a better equal to the Principle Engineer – still fairly optional, very high level, etc.

Yes it is such a shame that the roads are such that when I am on the road with my family some crazy daredevil can't drive 490km/h near us.

The roads are for getting from A to B, not racing. If you want to go 490km/h, go to a race track.
Did they burn out or did you mean they are lazy?
Limit it by law to a multiple of the lowest wage any worker or subcontractor earns.
Drivers are still a lot better at spotting pedestrians on tracks than autonomous systems. Autonomous train systems already exists, but those are completely enclosed systems, like a city metro system. Not a system where speeds reach 200 km/h, or even 100 km/h.

Bugattis are high-end collector's cars. The average Bugatti owner owns 84 cars, 3 jets, and a yacht:

You buy a Bugatti simply so you can say you have one.
Hmmm... I'm not sure where you work but I can talk about my experience

* I've learned a lot about architecture and scaling
* Maintainability of systems is something typically that people learn with experience
* there's a lot to learn from code reviews
* we have DataArch reviews, SecArch reviews, and I've got to learn so much from each of those (Akamai)

Apart from that - talking about Akamai specifically where I work -
* there's a program I'm currently enrolled in called "Intrapreneurship" where we are trained on all aspects of the business - marketing, finance, product management etc. in which I have learned so much
* I recently became a people manager - so there's a lot of training associated to that

So, if you feel you are not learning - it might be specific to your experience or a set of companies - but there are definitely companies which invest in their people - so actively look out for such opportunities.
I prefer The Great Discarder [1]; saves more memory, and Chrome starts very quickly even with thousands (really) of tabs open. To put another way, Chrome becomes usable almost immediately, with much less time elapsed than needed to shut down.

Tabs Outliner looks interesting. Is this a replacement for the "vertical tabs" extension I've seen others rave about for Firefox?

Absolutely, none of the current formal methods approach scale to the level of much commercial software. Much of the systems engineering work that we did at Altran was focused on minimising the extent of the system that would need the higher levels of verification. So flow analysis and absence of runtime error proofs were commonplace, but proof of correctness against the spec was something that was much more focused on specific very high integrity components.

I remember thinking that B was a heck of a lot of work for event the smallest projects. I'm kind of surprised that it's still being used.
Once again the IC cars manufacturers underperform. This is non-production car and very late to the party. Meanwhile Tesla Roadster, an EV car, is doing cool 4513 mph - or 15 times faster, with insane fuel economy of ~0.03 l/100km.

Joking aside, a really nice car I wouldn't mind owning!
I'd suggest any such benefit is largely psychological to the user. You can find nearly any style/color you want and branding is difficult to ascertain from any appreciable distance. I tend to buy memory metal half frame glasses and I can't tell the difference between the "knockoff" zenni and my $600 foolish pair I bought at a mall.
Im not saying they're gonna be classified as employees. Being classified as employees would make ridesharing horribly unprofitable.
HN is pretty snappy and lightweight, but there's still quite a bit of HTML bloat that could be removed. e.g. all the nested tables, divs, classnames and padding gifs are completely unnecessary, and could be replaced by a single nested list.
True, but that just makes the whole exercise even more pointless.

There's really no point in building a car that can go above 150km/h, but perhaps some of the aerodynamics can translate into more fuel efficient car.

I'm also slightly annoyed by the usage of the word "barrier". There's physical or perceived 300mph barrier. People have built cars that will go a super sonic speeds, so there was never any doubt that it would be possible. Admittedly it is a little funny that the Bugatti is faster than a Formula 1 car.
Pretty much all modern cars will go faster than is useful and/or safe. Only a small set of public roads allow cars to go their top speed. I have a 1991 Corvette that will go 153 mph, and I've only done it twice. It scares the crap out of me. Top speed is a cool thing to boast about, but most people won't ever see it, and a few stupid people will hurt themselves with it. That's okay on the balance, because millionaires are spending their money and supporting the economy. Buying one of these cars probably funds an engineer's salary and likely a few others supplying materials to Bugatti.

What? That makes no sense. The question here was why static linking is relevant to the point about whether or not having libc release together with the kernel means you could move the compatibility line to the libc interface, and I was answering that question.

Forbidding static linking libc is fine if you do that from the beginning. Linux didn't, so - whether or not you approve - there's statically linked binaries out there that must be supported. It's not about calling users stupid, or a discussion about what users should or shouldn't do - it's a discussion about what the kernel can do, today, given the backwards compatibility constraint and the reality on the ground. (Personally I am completely in favour of dynamic linking, but that's not the point).
Adding undo changed the feel of downvotes a little. Irreversible accidental downvotes were scattered randomly on comments and they made the occasional downvote feel less harsh.
This got me thinking. Once I thought it was fun, but the more I look at it, the more I feel it is utterly pointless.

A racing car has a function: to get around a track faster than other cars (over a period of laps). To do this, it needs to be versatile: turning, braking, acceleration, fuel consumption, range of vision and suspension (among others) play a role. That's the true engineering challenge. It's why it has wheels, not wings. But to simply go fast, seems a bit pointless to me.

Yeah, that's the folk wisdom on sendmail. But really, since version 8.0, writing your own .cf (or reading it) should have been regarded as bizarre as crafting your own object files with an hex editor. And sendmail has served me well, over the years; its scariest feature (sendmail.cf) is also a strength - as a Turing complete programmiong language, it allows you to tie your incoming/outgoing mail in square knots, if you feel so inclined, or to solve some unforeseen mail routing configuration/problem/whatever. Of course, if you find someone that has gone to the lenght to write a _LOCAL ruleset that does it - and alas that is a creaft I do not possess, and is dying out. When it does, I will probably make the postfix jump.

I cannot claim prescience, because I started ont the trade when sendmail was THE mail program (though ed was no longer THE text editor): but consider, had I listened to the sendmail bashing crowd a couple years later I would have gone qmail (!!!). For not having done that, I thank the almighty weekly.
Everyone that wants to get into tech investing should read about Mark Twains misadventures in investing. Current stories about tech investing and investing in general are greatly affected by survivor bias. If you are not a successful investor you do not become famous your story does not get told, so many more people get to make the same mistakes you did.

Mark Twain on the other hand was famous for a completely different reason, and he is a great story teller to top it off. So his stories did get told. And they are very illuminating about how difficult technology investing really is.

He was very lucky in this watch investment story. I am sure he was able to get most of his money back mostly because he was famous and he threatened to expose the watchmakers about their shady dealings. The ordinary person in his place would have suffered more losses.

Another very illuminating story is his investment in automatic type setting machines. Here one would think he had all the advantages. He had worked as a type setter as a kid and as a journalist later on. As a writer he worked with many publishers. He was very familiar with the printing and news paper industries. He knew very well that an automatic type setting machine was sorely needed and would make much money. And he was right, an automatic typesetting machine did make lots of money, but not the one he invested in. The company he invested in failed.

So yeah ... tech investing is not easy.
My old boss had his Ferrari fitted with winter tires to drive it year round in Denmark. His logic: Why should I only be able to drive the car I love driving 5 month a year. (That answer is related to the heater, or lack there of, in a Ferrari. It is apparently really cold driving it in January)

I like that approach a lot more. What the point of having an awesome car, if you're afraid to drive it.
