> The thing that's gotten smaller is the minimum feature size on a silicon wafer.

No, even minimum feature size is improving much slower than in the past. Fabs are focusing on specifics that are still giving gain: lower power transistors, SRAM. Really high performance transistors like for amps have not gotten much smaller, DRAM has not gotten much smaller, analog has not gotten much smaller.

The capacitors and sense amplifiers in DRAM have not gotten smaller nearly as fast as any of the other features.

> DRAM chips are integrated circuts that consist of individual transistors and capacitors for each bit, plus the wiring and logic to read, refresh, and write to those bits.

I know what a DRAM is...
Has anyone tried the software in Ubuntu 20.04? I am sutck with an old version of Ubuntu.
In reality, other nations use the force of law to restrict the free market in their domain forcing countries that have more fair and free markets like the US to subsidize the other countries' artificially set prices. I am not saying the drug companies have no blame to shoulder, they have plenty. Just know that this isn't just a simple case of an evil capitalist trying to price gouge.
It was flagged by users. That's the most common reason why posts plummet.
I believe it was Nick Land who described cities as “IQ shredders”; they attract high intelligence people from rural areas and then immediately tank their birth rate.
Are you assuming all of these companies are going after the same top talent? There are plenty of average and above average talent who they can hire and not "bleed". You don't need to hire a team of Ken Thompsons to build a CRUD service.

If companies would stick to hiring the developers they can afford given the needs of whatever project they are hiring for, there would be no (or less drastic) upward spiral of labor cost.
Is this a reference to the first Presidential debate?

As a diabetic I was excited to hear when Trump said that he had made Insulin as cheap as water.

However it still looks like it costs around $300 per vial at my pharmacy.
Don't need to go back 2 weeks to find negative posts about other automakers.

The top article on Jalopnik right now: "The Mercedes G-Wagen Is Objectively Impressive But Still A Dumb Car"

The next article: "Jaguar XE And XF Sportbrake Wagon: Dead"

Followed by "Mercedes-Benz Gives Up On Manuals"

Meanwhile, after a Tesla suffered catastrophic structural failure that could have killed or maimed someone, the title of the related article is simply: " Brand-New Tesla Model Y's Roof Flies Off on First Drive Home."
The earn it bill is already unenforceable. open source crypto already exists and is available everywhere. so yea. good luck stopping people from using it.
It's good fun. but who really needs to improve their typing in 2020? Now that we can dictate directly to computers to do the job.
Which is a good thing right?

All questions and their solutions should be exposed, so big tech can get to work on fixing their interview process?
The cartoon fox is really infantilizing. I know probability is tricky and sometimes counterintuitive, and I appreciate being taught things, but don't treat me like I'm in kindergarten.
The choice of data sample for your "how to" video... oof.

Also, watching how you enter ~20 datapoints is quite soporific.
1. Maybe not devastating to your particular class of society. Motor accidents are not as strongly linked to economic despair either, and certainly not an effect of ideological choice.

2. It's hard to deny that the cause of this is not fundamentally caused by an over emphasis on free market ideology.
> The python test could've been a bit better if the code was in a main function.

Interesting. Didn't try that. I'll give it a go.

And yes, NodeJS is a massive project compared to Python. But I think the performance difference, has at least something to do with language design. Javascript is more primitive language than Python so it is much easier to write a really fast interpreter for it.
I really like Baselet.jl[1] which provides Tuple-specialised implementations for a bunch of Base APIs that the compiler is very good at unrolling :)

The bad faith assumption is reducing an entire article to some alleged motivation that the article didn't say.

If you're looking to have interesting conversation about similar experiences, that's great and definitely on topic, but you'd need to go about it differently. What you posted sounded snarky and reductionist.
It’s amazing how many people are going out of their way to prove your point.
Valuable where exactly. It's good that that's defined clearly in readme at least so that contributors don't waste time. And value of such contributions are defined by project itself and those responsible for it.
PS I can imagine rules like that to appear in some opensource projects after tha recent pandemic of the "awesome project" PRs.
I was looking for an update just a few days ago, but didn't find anything. No code, no blog posts nothing. So thank you for this, as I'd lost hope.

This seems like great progress. I'll be donating a bit!
I would agree that it supports your point. Proves it? no.

In the case of Apple / Google / Pixar / etc., yes. They are definitely trying to grab every Ken Thompson they can. For Google in particular, I believe it is part of their hiring goals.
What, we're not allowed to downvote jokes that aren't particularly funny?
I think the theory is that if you own Fb & Google, you can put your thumb on the scales of what content people see. There's clear evidence of this happening to certain news sites, although I think for an election candidate I doubt they would dare.

Perhaps because engineers are male.

Men aren't acculturated to be especially good at empathy. We're taught that the default person is us: healthy, male, straight, white, etc. Everybody who deviates from that is suffering from a handicap, and they need to find their own accommodations.

I'm sure the question did pop up, and the answer was, "Well, I guess you're not going to drive." Discussions of equality arose quite late, and nearly always come with a pushback of "It's too much trouble to change things just to make life easier for you."

It's why drugs are often approved without being tested on women or black people, and we discover only belatedly that there are problems for that "minority". It's why we didn't have female crash test dummies until 2003.

We design for the "median" person around us, and that median person doesn't have color blindness. There were probably zero red/green blind people in the room where it happened, or perhaps just one who was easily overruled.
Who cares? The point is that it's their problem, you don't need to think about it, it's done for you. =)

In practice your application restarts at least once a week. It's transparent because a new instance is started first and takes over. The provider can move applications around to add/drain servers and perform maintenance.
You bought access to X servers knowingly (because you can't do that by accident), let them sit here knowingly, then got billed the exact number that was listed, but somehow that's DigitalOcean's fault ?
I am currently trying to fix a program that was made by a person that didn't knew those details of MySQL...

Most weirdly, the fact that the default collation is SWEDISH.

It is a complete freak show, the users kinda got used to it, butchering our language (portuguese) to use only characters valid in english, hoping MySQL won't barf spetacularly on them.
I think you'd sooner see wages fall than rise. People are working those salaries in cheap areas because they couldn't get a higher salary elsewhere, after all. There is a finite amount of these highly paid positions and far more qualified people.
Makes sense. Thank you for your comments.
> transcribe solos

Do you mean learn other people's songs from sheet music, or do you mean write down, from the sheet music, the same song again on blank sheet paper?

Edit: Or do you mean write down the song via hearing?
> The reality is opposite the title - humans are far more distinct, especially on group levels, than is commonly understood.

This really seems to have some huge assumptions in there. What is commonly understood? I don't think there is much common understanding associated with this. Except maybe that we should treat individuals as individuals, rather than make strong distinctions based on group membership, regardless of any underlying distinctions in the groups. At least that's the noble intent -- I don't think any lies are layered on this.

Did the folks creating the containers in the article believe themselves to be creating unsafe storage? I doubt it. Our current situation is no different. We think it's safe because we haven't seen it break, when we do see it break it will be in an unexpected way, probably ahead of the time we thought it'd break.

97 of 535 Congresspeople are in their first term this session. That's a healthy amount of turnover every few years. The average term in Congress is for people serving after 1950 is 12 years, so two terms.

Yeah, some Congresspeople operate in "safe" districts and never see a challenger, but those are rare (and valuable).

The article state that it does send over at least 1 key-frame.
That might be used to find coefficients in a much smaller model, similar to how Active Appearance Models approximate a lot of faces with a relatively small model.
> You gotta play it.

If you want a job in those companies, sure. But if you want a decent job in a decent software company, you don't have to go through all that show. There are companies that don't ask that sort of questions and instead they interview you in a sane manner (they ask about past experience, they let you talk about what you actually know... The whole interview feels like a conversation).
The etymology isn't mysterious. The primary sources clearly indicate that the first appearance was the Anglo-Saxon word "wicing", meaning "pirate." The Wikipedia references to the other names are from the Middle Ages, a time period that almost entirely post-dated the Viking era. It is unsurprising that the word Viking should originate from Anglo-Saxon, since the Anglo-Saxons are the source of the vast majority of written records about the vikings. The Norse did not keep written records of themselves unless you count runes, which wouldn't have contained such a word. Indeed, the earliest written records of the Viking "skalds" (poems), in the Codex Regius, were written some time in the 1200's.

The Vikings really do deserve their "out sized" influence, though. They were an incredible lot, ranging geographically further than any human civilization until the Portuguese discovered Australia. They could be found at various times in present day Canada, Turkey, Russia, and parts of Africa.
100 years ago correspondence courses enabled people who could not afford college get college degrees. My grandfather earned a college degree this way, and liked the setup so much he made his career distributing correspondence college courses. He met my grandmother having sold her courses on mechanical engineering.

This is one of my favorite classics of Hacker News: searching for the nefarious companies behind the anti-trust action.

It's interesting because it's clearly an attempt to take populist suspicion of corporations and redirect it towards opposing a policy that would reduce consolidated control in markets.
I think the cartoon fox was just because they need a graphic. The real way they are combating people's inability to interpret percentages is by dropping them lower down, and replacing the top line prediction with the word "slightly favored" or "favored" or "strongly favored".

If you could point me to a <20W machine with ECC memory that I can buy online like a mere mortal human person, then I'd very interested!

The only thing that comes to mind in that category for me is the PC Engines APU2. The APU2 is a very neat piece of kit, don't get me wrong, but it being the only option is not great either.
I'm not convinced that's true. If the market really is free and fair, and the price is currently 8 times more than elsewhere, why are foreign pharmaceutical companies not flooding the US market?

Why are there not dozens of silicon valley startups springing up to 'disrupt' this market - clearly there are large margins to be made given the price is so much higher at the moment.

It sounds more like some regulatory capture has happened which is keeping prices artificially high, than that all other countries are artificially low.
Fascinating! Can you share how this can be used to develop a physical theory with no axioms?
Yes to both. Exercise generally helps. Yes to vitamin D (there’s a great long vitamin PDF on COVID for like $15). Yes to sunshine. Trying to walk with a mask daily.

Honestly the base hypothesis is that it’s the societal change, and not the n=1 study.
Wait, you mean the low international price of a medicine that was developed and given to humanity for free is now somehow a burden on US drug companies? I doubt it.
You people are idiots.
I actually tried really hard to get RAM to corrupt a bit for a school project and didn't manage a single bit flip.

How often have you actually heard of data corruption due to non-ECC memory? Either yourself, any degree of 'friend of a friend', or perhaps a study that looked into the matter with more success than I had. I don't mean a newspaper story because exceptional cases are reported because they're rare exceptions rather than common enough that we'd be likely to come across it in our lifetimes.
What I don't understand is this: The Singularity Theorems already assume the existence of a trapped surface (and by implication, of a marginally outer trapped surface, i.e. an apparent horizon, i.e. a black hole) and then conclude that there must be a singularity inside.

Experimentally, though, we know absolutely nothing about this and the recent black hole-related discoveries (gravitational waves, Event Horizon Telescope) can certainly not be seen as a proof of the existence of singularities, either.

Now the Nobel Prize committee says that the discovery is actually

> “for the discovery that black hole formation is a robust prediction of the general theory of relativity.”

But this has virtually nothing to do with the most famous piece of work by Penrose, i.e. the Singularity Theorems.
Just apply to any non-famous software company (95% of the software companies in Amsterdam) and you will find decent interviews (no tricky tests).
The headline should include the name Sir Roger Penrose, because he was awarded 1/2 the prize. Andrea Ghez and Reinhard Genzel were each awarded 1/4 of the prize.

Burying the lede like this only undermines our trust in the very institutions we need most today. Please see these two videos by Eric Weinstein for a deeper explanation of what I am only hinting at:

They're fun problems though typically.

Don't problems have to be rotated eventually anyway? You'd think otherwise there would be secret silos of problems and those in the know will have much better results than anyone else.
Not depressed. Have therapist.

You’re likely correct. Psychological from social changes seems most likely thing.
Booking.com feels like a particularly Silicon Valley-savvy European company. They seemed to be an early adopter of HN: Who's Hiring? threads, for instance.
Not the same thing. You're still in the same physical space.

Again, that time on the bike/train/car provides head space to mentally context switch away from work time and into home time.

Funny you should say that, because some Vikings became Normans and occupied England which later became the British Empire.
Serverless workshop: Building a ride-hailing service
I went through a receipt survey filling-out phase. I noticed the majority of survey questions simply aren't realistic. The questions are geared towards brand management metrics and not the actual product/experience I'm trying to leave feedback on.

There's no reason for me to give a 10/10 recommendation to my friends and family about my local pizza hut. I don't think about brand-trust in terms of a 5 point likert scale. I don't expect the teenager making my chicken sandwich to go above and beyond my expectations for a $9 value meal. But I know if I leave her a 3/5 that'll be considered an unsatisfactory score.

I really wish these surveys were more casual and qualitative. It's fine to just be satisfied and not have everything quantized on a scale detached from expectations.
Yeah I tried for the first time. Was roughly 300mg? For the first hour I was a bit off, but then it cleared and I felt very straightforward and open emotionally all day. Could definitely see it being useful for a date.

What's your dose, is it extract or raw material?
I'm just going to use this list to steal a problem for my interviews.

It's hard to find a problem that is good at selecting candidates yet doable in 30-60 minutes and different from the problems other colleagues use in their interviews. Most problems are either too difficult or too easy.

A message board centered around startup accelerator might be expected to have a median temperament closer to a startup than a 100 year old accounting firm.
It really makes you wonder how this will go down in the next 5 years. Rents are high in cities because of highly paid workers who are capable of paying those rents. Now the middle class is priced out because their wages have been stagnant despite highly paid workers reliably getting raises. Either wages for the middle class has to go up dramatically, or rents have to crash, and rents aren't going to crash if the whole reason why they went up is because demand from highly paid workers, who haven't gone away. Something will have to give, people can't live in their parents house or commute 3 hours one way forever.
As I was reading, I was reminded of schema-migration definitions which some ORMs/DB tools give you (I currently use Knexjs). There might be a useful intuitive correlation there [edit: I see jka and the post already pointed that out]. Of course in the context that I&S is discussing, the migration is at “runtime” (so to speak) because we’re dealing with systems that can’t do all-at-once migrations. Like intrepidhero commented, I’m curious to know if declarative lenses will be sufficient for the task, but I’m glad that’s what they explored. I’ll be reading this post again more closely in the future.

I've heard this before and dont understand the reasons - is it really just an oligopoly ripping us off? I rarely trust newpaper articles because it is so politicized, but this looks like it really is.

Also I understand there are newer Insulins which may have a patent, but the original is 100 years old and patent was not an issue. Why aren't there more manufacturers?
Looks like we've not learned anything from 2016.
The more I read about the Middle Ages now that I'm an adult, the more I learn that the whole time period from 500-1500 is more complicated than I was taught in school. It makes sense that the Vikings would be more complicated too.
Given the varying level of regulations in different countries "up to" means nothing where medical care is concerned.

What matters most is what are the prices in countries with equally strict quality controls, which would be, unless I'm mistaken, the EU, the British Commonwealth, Japan, and a few other places.

And the answer to that question seems to be >6x which is bad enough.

One of the things I've learned about persuasion is that I'm never, ever, going to persuade some people. What I can do is persuade people who can do it for me. In many cases, then, my time and effort is best spent on recruiting the folks who are good at explaining to others. In my experience most of these people can smell bullshit coming a mile away, and so if the first 'fact' out of my mouth is reproachable, I've already put them on the defensive.

I often hear, "we should be doing better than second and third world countries, so I'll list them too", that's a dangerous gambit. You're effectively appealing to nationalism and/or racism - we can't let 'those people' beat us. It's ugly, and if you have to stoop to that, is it really worth winning? It's no good living forever if you can't live with yourself.
