Postgres is copy on write. (A modified record is copied to a new page when written, and the old record left in place till a vacuum).

ZFS is Copy-on-write (One byte written in a block requires the whole block be rewritten, with the old one scheduled for reclamation).

The underlying SSD wear levelling algorithm is Copy on Write (Writing a single byte involves writing the data from the page to a new block, and then erasing the old one sometime later)

That means a tiny 1 byte modification to a postgres record involves creating many new unnecessary copies of a lot of data...

I imagine that if the three layers could be combined, dramatic performance benefits could happen, since written data might go down by an order of magnitude at least....

Won’t that solution make it harder for students from economically disadvantaged backgrounds to get loans? Or is the idea here that universities would be prohibited from applying risk management to their loan portfolio?
The clearnet is still a bit of a wild west (albeit now a heavily commercialized one). There's all sort of stuff that shouldn't be there, and if you go to report it to get it taken down, it's there a month later (hate speech, revenge porn, doxxing etc). Tor / Onionland is even more so a wild west, but that's the double-edged sword of anonymity & free speech. Anonymous voices & actions are sometimes the best voices & actions, but also horrific in equal measure.

That said, dubbing yourself 'unstoppable' & 'uncensorable' just paints a huge target on your back.

"A collision is possible but the total number of unique keys generated is so large that the possibility of a collision is almost zero. As per Wikipedia, the number of UUIDs generated to have atleast 1 collision is 2.71 quintillion. This is equivalent to generating around 1 billion UUIDs per second for about 85 years."
That syntax seems a bit verbose for a column that will most likely appear on every table you ever create. How about:

Ideally you'd also get ad-free access to Twitter itself, which I would certainly consider paying for. Considering the annual per-user revenue is ~ 12USD [1], this seems like something that would be financially interesting to Twitter.

Supports is not a strong enough word for an organization whose founder and chief executive officer previously led the public policy team at Google, or another in which Google is one of three partners.

It's not like Google made a donation to an organization that already existed which they happen to agree with. Without Google, these organizations wouldn't exist.

Which would all be fine, if Google made that clear when referencing them.

When some organization makes a public statement, don't you like to know who financed them?
Regarding institutional incentives, it’s like this - company self-reports, is able to consider itself a victim of the person - that they were defrauded just like the Navy. They may or may not be bringing their own action against the former employee, but have every incentive to even bring something token just to get the ruling and make their victim status official. If they can be classified as a victim of the same fraud (by court, by DOJ) they can’t be held liable for the fraud. There may be some other liability the company has exposure to but this would take care of the lions share of it. Self-reporting in this framework is far better than incentivizing a cover-up. Company will likely still have an asterisk by their name insofar as contracts are concerned and have to spend a metric ton paying the audit grifters.

I feel dumb for not having thought of this before. Anything like this you use regularly? regardless of language ,tool, framework, etc
That’s a gross oversimplification of reality - to the point of outright falsehood.

Michigan can’t get any electricity from Nevada today - they are on different grid ties, and there would need to be a ton of upgrades in the DC-DC and VFT ties between them to get that significant a chunk of electricity sent the ~2000 miles from Nevada to Detroit.

It's extremely easy to arrive at false generalizations by considering only the subset of the data that makes the strongest impression on you. On the internet, including HN, what makes the strongest impression are all the things that aggravate and activate and rub us the wrong way. The positive and innocuous portions of the data set, of which there are plenty, get left out of this generalization. You would arrive at opposite conclusions with different data points.

Supercilious putdowns of the rest of the community are notoriously even easier and more tempting than other forms of this cognitive bias, because they gratify other motivations too. They predictably lead to lame and tedious discussion, which is why we have that guideline. Here are some congruent things to do instead:

(1) leave the community if you feel it's so bad;

(2) post substantive contributions that make things less bad;

(3) find how you yourself are doing the thing you complain about, and change that aspect.

The business world has a jargon term, "solutions provider". The idea is that they strive to not just provide you a tool, but to fully solve your problem, to make it entirely go away. It's often just a buzzword, but like most buzzwords, there's a kernel of useful truth in the middle of it.

The medical industry is not a solutions provider. You should view them as a useful tool, but one that still leaves you with the responsibility to utilize the useful tool to solve your problems.

I am not making a normative claim here; I'm making a descriptive one. The medical system is an incredible toolset, but you need to be ready to assemble it into a solution. Maybe it should be a solutions provider. Maybe it's really discriminatory against the people who won't or can't operate this way. No argument. But it observably isn't a solutions provider today, whatever "should" be.

In this particular case, if you care you should have scheduled a followup with a different doctor. ER doctors don't do that sort of analysis.
Low-ranking but expensive private colleges are such a racket, overall. Paying $100k for Brown has a way higher ROI than paying $100k for No-name U.
I’m all for artificial scarcity. Collectors are going to find rare things to collect. It would be better if they didn’t, but I think it’s probably a part of human nature to some degree.

Personally, id be ecstatic if collectors decide they can get their fix collecting rare jpegs and Pokémon cards instead of “truly scare” ivory, furs, or blood diamonds.

What’s the harm? What am I missing?
Absolutely. I work at a well known tech company, and when we give potential candidates coding tests we give them the option to code in any language they'd like (including pseudo-code), and to use Google if they can't remember the name or syntax of something they want to use.

There's not reason to fail a candidate just because they can't remember the signature of a method in a library they haven't used in a while.

This happened at an aerospace company I worked for. Someone didn't read the paperwork closely and missed a critical yet very benign step in running a job. Engineer receives an angry wtf email from the customer which explained that because this detail was missed, the entire lot had to be scrapped. The engineer knew all too well the legal ramifications of lying so he directly told the customer "oops. our bad." This bypassed management causing a shit storm as there was no way to "smooth it over" once he admitted fault. Customer sued the company and they had to pay big $$$ to pay for the scrapped lot. Engineer was senior so all that happened was a chewing by the CEO.

> Trust me when I say people who pirate are usually the ones who never ever buy video games

Why would we trust you? This is just you speaking for yourself.

I used to pirate and when I couldn't, I bought the games. I'm probably not the only one.

The fact that publishers routinely spend millions of dollars on DRM is evidence that DRM works at protecting their sales. They wouldn't throw this kind of money with hundreds of experts crunching the numbers if it wasn't valuable for them.

Money speaks, while you are just making claims without any evidence.
Let me ask you, let's say that I get one of these artists to draw up a contract and sell me one of their peices of art. Do you think it will command the same value, more value or less value than the equivalent NFT associated with it?

Becuase I take a look at this and it looks to me like all of this commercial activity has basically nothing to do with the art. I would kind of get it if you pointed to me to a guy whose selling peices of art for a few bucks, maybe $50-100 and selling a decent number of them who you know... like the art. But what market is this? These aren't art collectors who are just using the new medium is it. They're not fans of the art. They don't have thousands invested in traditional collections. They're not going to buy the same art, but off-chain. So is this really anything to do with paying artists at all? Who are these people who are suddenly rushing to pay thousands of dollars to artists?

Is this "StarryNight" who paid $2000 for this NFT excited to be supporting xcopy. Or is it the account of the venture capital fund of the same name? That's not exactly the story of giving power to creators that we were being told is it?

I think the problem here on HN is actually the opposite of what you're stating- the second you do do an ounce of research these claims start looking more and more fishy.
Language like "self-inflicted wound" suggests there was either some strong objection to generics or that everyone was unaware they wanted them. That's not true.

There's never been a strong design opposition to generics among the Go developers (note "the X developers" as distinct from the weird fanboy communities today of "X developers"), but it's always been balanced against other priorities, particularly compiler speed. C# and Java aren't quite so ready to throw stones in that area.

That being said, I don't think it's some uniquely praiseworthy thing either. For me that's actually more for things like `strings.Cut`; too many languages refuse to use their stdlib as a tool to push good design, especially good "micro-design".

Perhaps it becomes clear when you realize that your NFT trials come from your tech background and surely not from your art background.

Most people don't earn any money on NFT and almost definitely not people without a tech background and a small name reconnaissance.

Eg. Who does your graphic design for the NFT's?
Why does a 5th year undergrad extension make sense but not a non-thesis masters? They are effectively the same thing right? Additional classes?
Are you sure? I think this is pure speculation on your part.
They are not similar enough for the purpose of validating the intrinsic (as opposed to strictly monetary) value of NFTs.

Only a subset of people purchase baseball cards (or any collectible for that matter) exclusive as an investment, and even if I bought Action Comics #1 mostly due to its monetary value, it is not just a token, it is an actual artistic object that can be appreciated for it's intrinsic and historical qualities.

Does the same can be said about NFTs? I don't even know what an NFT is, objectively. A string of bytes? If so, does people appreciate its binary code or whatever? Whatta fuck is it? A virtual contract that states you own real state on the third moon of a planet that does not exist?

No, collectibles are not an apt comparison, and this argument only serves to show how its proponents are detached from reality...

Besides, even the generations you mention usually purchase things that can be artistically appreciated somehow. If I purchase a Fortnite skin, I'm purchasing the ability of having that skin applied to my character. It is something I enjoy looking at, having the knowledge that others can look at it as well. I cannot hold it in my hands, but it has some kind of existence. NFTs are not like that at all. They're like contacts in which the only guarantee is the payment one can collect.

But I suppose even programmers need a mysticism...

It's usually white people accusing minorities of being "internalized white supremacists" though, and I can't think of anything more patronizing to minorities than that. Especially since it's usually whenever a minority does something they don't agree with ("they are going against their own self interest which should be to agree with me") so it completely reeks of white saviorism. I'm not saying that's what you are doing here, it's just that in my own experience it's rhetoric that is almost always used in a way to shutdown any criticism/dissent (and very rarely from someone who is part of a minority). A good example of that would be how non-whites are quickly labeled "low information voters" when they don't toe the party line.

Obviously everyone can be racist or bigoted, regardless of race but that doesn't mean they are internalizing white supremacy whenre they aren't white, it just means they are racist. Its weird to make everything all about white people and the whole concept is increasingly sounding like a way to cope with bruised savior egos.

> Apple’s iPhone-centricity could be a liability, much as Microsoft’s Windows-centricity was a liability once mobile came along.

The iPhone and wireless connection to it could make the glasses a lot lighter, basically a mobile server. Apple is rollling out a wearable system, they distribute the platform across their wireless earphones, watch and phone, maybe even using their computers to power the glasses when you're at home. They already got a large part of it deployed and used by people..

Speculation warning.

I would imagine a higher up got very angry every time a batch failed.

> Tech pay is sky high because US is overvaluing US talent

This statement feels like it requires a lot of justification. I work for a large company, we are happy to hire out of Europe, SA, or anywhere else so long as they can work on their team's time zone. We are willing to beat basically any offer you'd imagine getting in those areas and hiring is still hard, qualified and experienced people are a rarity.

When thinking about "overvaluing talent" it's worth remembering that just 5 years ago the big tech companies actively conspired to keep pay down because margins on developers making 120-150k were just insanely high[0].
