The GameStop thing was some trying to emulate the shitty behaviour of hedge funds and succeeding. The authorities had to intervene to stop these people. Even Robinhood had to disable trading for these people, otherwise who knows how long it could have gone on. The authorities are mum when the hedge funds do it.

'Changed, prayed, took stupid selfies' - let's not hide what they did. They had weapons. If an angry crowd with weapons come to my workplace and ransacked the place, making everyone flee for their lives, I would want them all to serve prison time. It's a no-brainer.
I hope to understand the ecosystem better ... and imagine that at some point the greener operation and greater utility of Ethereum ETH 2.0 will beat out Bitcoin.

Will this lead to better returns for Ethereum over Bitcoin medium- or long-term, eventually? When will that switchover happen (if not already)?
Not entirely true. PoW's centralisation risk increases as bigger blocks mean longer network propagation and hence higher orphan rates.

PoS determine the list of proposers in advance, meaning no orphan risks.
Just like the stock market was never about cashing out during the 1920s. But that situation can change very fast. In fact, the only reason Bitcoin wasn't wiped out during the last panic in 2017 is because no one was stopping Tether from simply minting out of thin air and propping up the price.

The simple fact is that every dollar spent buying a new lambo by some crypto hotshot millionaire has to come from someone else buying their ticket to the carousel. Just like in any Ponzi scheme. There is no creation of value there, just an ever increasing pool of greater fools.

And now we even have companies with millions/billions of dollars worth of BTC on their balance sheet. What happens if one of those companies goes to bankruptcy court? Do you think their equity and debt holders won't want those tokens converted to fiat currency as soon as possible? How do you think that happens?

If you're truly paranoid about the government seizing your assets (which you have no reason to be unless you're already doing something stupid), you can always buy a precious metal or simply take out cash and keep it buried in your backyard.

Also, 1÷ of global emissions is already a huge number. And if Bitcoin should become as widespread as some people claim that number would still need to grow by a vast amount.
Sometimes your job has few or no inter-task dependencies and so there's no need to share between threads, but there's a heck of a lot of work that needs to be completed.

MongoDB's stock price is quite remarkable, given how dismissive a lot of people (including myself) on HacherNews have been of their offering.

It goes to show that HackerNews consensus != reality.

Read The Economist religiously. It will make you better faster.

You can read the Economist if you'd like, but it won't make you a better entrepreneur. Instead, find people who are smarter than you (in your area), do everything you can to convince them to spare you some of their time, and then be a humble (but discerning) sponge of information.

The challenge in fast changing markets is that the best information isn't written down anywhere (and especially not in magazines!), but that it's locked inside people's heads.

At least, this is what has worked for me (TimescaleDB founder)!
A graph would be good. Any graph. Preferably multiple. Otherwise, this is all empirical data. Show me why Rust wins, and how. Telling me "doubly-linked lists are slow" is not useful, as a developer considering one of these two languages.
Isn’t that what the World Trade Organization (WTO) is for?
Glad I’m not the only one - getting research projects replicated was insanely difficult with PCL interacting with external libs. I must’ve spent days getting cmake happy with getting a cross-compiled setup working properly. I’m seriously considering trying to move the important bits to rust, but it’s just such a large project.
I’m not so sure. Currently each validator has about 60k usd (32 eth) staked. They are disincentivized from misbehaving / attacking the network by the threat of their eth being slashed (and there are clear rules about how this happens).

To me, it seems that as the value of that ether increases, they have more incentive to behave, rather than risk the loss of their investment + large capital gain.
You could attach a simple lightweight drag sail or a Echo style very low pressure balloon. That can increase drag of the thing by orders of magnitude and get it down fast while you tug goes for the next target or returns for refueling or restocking.
You own the hardware, which means you have the ability to boot the system into diagnostic or repair modes for extended privileges. This doesn't mean that during normal operation there should be a superuser account with 100% access. Plan9 from Bell Labs pioneered (edit: they probably weren't the first, but it's the first OS I can think of that does this pervasively -- I bet mainframe systems are similar but that ain't my cup of tea) the idea back in the 90s, where certain processes (like the credential store factotum) were sealed off even from the root equivalent.

If you had physical access, you could add a flag at boot to enable access to these services, but this was not enabled by default, which is good.
You should think of miners as bodyguards. They aren't intended to be active participants on the network, they are intended to provide the service of securing the network and serving the interests of the users of the network.

If a group of bodyguards at a concert vote democratically and 51% of them decide the singer shouldn't be allowed to go on stage and sing (because of a grudge or whatever), is that a problem? Yes absolutely that's a problem, and probably all of them are going to get fired.

Same sort of idea here. If the miners aren't serving the best interests of the network, the network has no obligation to continue paying the miners tens of millions of dollars per day (no joke, that's how much miners on Ethereum make in revenue right now) to continue sticking around.
“Total cost zero”.

The cost is never zero. Doctors, nurses, don’t work for free. Infrastructure isn’t maintained without money. It comes from somewhere.
I think we can talk about history - and Black history - without it having to fulfill some external function like making people feel good or bad or inspired or whatever. At the very least it's just one more historic anecdote about how bigotry kneecaps entrepreneurship and stifles talent - so we should strive to judge people by their character and talents and not conscious or unconscious biases or what social convention dictates.

Also - why a company might have failed is always relevant to discuss even if it leads you somewhere uncomfortable.

> (regardless of what you feel about the speech or conservatives, it should be trivially obvious that they are not furious about a "non-insane" speech)

I guess it could be implying that being furious about insane speeches is normal, and "non-insane" is what makes it news? Just for devil's advocate sake.
Another way to describe this could be that the meaning here is inherently ambiguous between "is-a" and "has-a", but the puzzle only makes sense (and only has a solution) if you interpret as "is-a".

In Mystery Hunt puzzles, which this originally was, "we have to interpret this in a way that would allow there to be a meaningful and unique solution" is not only a perfectly legitimate form of reasoning, but often necessary!

It's not really exactly the same kind of reasoning, but in a puzzle I wrote a year before this for the same event

https://www.mit.edu/~puzzle/2012/puzzles/into_the_woodstock/...

you could look at it and say "hiragana is only ever allowed to be used to write Japanese!!!" but insisting on that rule (much as it applies in most situations) wouldn't give the puzzle a meaningful solution. :-)

Maybe a closer equivalent would be that in this year's Mystery Hunt, there was a puzzle using a set of variant Hashiwokakeru (Bridges) logic puzzles. There were hints about which rules were changed but it wasn't stated whether the rule changes applied individually (one puzzle each) or cumulatively (when rules get changed, they don't change back afterward), or some other way. So, it was necessary to make assumptions about what was meant and see whether they allowed a solution. That's typically considered fair and appropriate throughout Mystery Hunt-land.
Show me some numbers please, or I’ll just take it as another list of wishes that Rust fans think/want to be true.

Says the guy who raised 10s of millions of venture capital, used that to build himself up, pissed the company down the drain, and is now selling a fake story about his great successes. Yeah, startup PTSD doesn't apply to you because you don't care for anyone besides yourself. People like you are just making it worse.
I'm not going to read all 29 pages at this hour, but the chart on page 5 clearly indicates that patients with teeth should be getting 4BW every 2-3 years at the longest.

Note: if a dentist or hygienist notices something, it doesn't matter if you had FMX or pano 3 months ago. Getting another BW or PA can make the difference between a tiny filling and lots of discomfort.
Wow, that's a very pretty magenta!
Looks nice in headings, but I found the text on this page difficult to read. As in, it actually irritated my eyes. I wouldn't use this in running text (for which serif fonts are better in any case, as most books on typography recommend).
Oh wow I didn't realize there was a phrase embedded in there. Amazing.
Database startups suffer from an extreme case of an important truism in startups generally: the product you think you are selling is not the product the customer thinks they are buying. No one buys a database per se, they are just a means to some other end.

People that love database technology — that would be me — tend to start database companies. It is very difficult to sell a database. It is much, much easier to sell a compelling solution to a somewhat boring but very valuable business problem that just happens to require an amazing database capability behind it. That’s your moat, the customer doesn’t actually care that there is an amazing database engine behind it but it makes it difficult for competitors to replicate.

> C libraries typically return opaque pointers to their data structures, to hide implementation details and ensure there's only one copy of each instance of the struct. This costs heap allocations and pointer indirections. Rust's built-in privacy, unique ownership rules, and coding conventions let libraries expose their objects by value

The primary reason c libraries do this is not for safety, but to maintain ABI compatibility. Rust eschews dynamic linking, which is why it doesn't bother. Common lisp, for instance, does the same thing as c, for similar reasons: the layout of structures may change, and existing code in the image has to be able to deal with it.

> Rust by default can inline functions from the standard library, dependencies, and other compilation units. In C I'm sometimes reluctant to split files or use libraries, because it affects inlining

This is again because c is conventionally dynamically linked, and rust statically linked. If you use LTO, cross-module inlining will happen.
“Total out of pocket cost zero, with taxes funding a functioning care driven universal healthcare system.”

We’re not arguing that funding is required, simply how it flows and to whom.

I absolutely agree. I work on a Mac but have to remote into a windows machine daily and this still trips me up. The Microsoft Remote Desktop app had the option to keep some Mac shortcuts for copy paste and such but it’s still an absolute usability nightmare.

I used windows machines an overwhelming majority of my life but I find the Mac OS shortcuts to just be much easier to remember and reach with one hand. For example cmd Q for quit as opposed to alt f4 just makes sense.

So you don't believe there's a moral backing for the concept of a protected class? And do you think "political views" fall into that category? Additionally, do you think it's "political views" themselves that are under threat here? Has anyone been banned from any social media platform entirely for speaking about cutting/raising taxes or growing/shrinking government?
Disregarding the clinical definition of PTSD as I'm not qualified to diagnose, I will answer a slightly different question:

"Is _career trauma_ real and possible?"

Yes, absolutely.

I had an experience early in my career where I was working with a partner who was toxic, and over months and months I became more and more stressed out, and eventually I ended up having health problems. I finally had to end the partnership, and my health improved significantly -- but I was deeply burned out for a while, it took a long time to get all the way back to productivity.

So yeah, trauma in your work life is very real, it happens to many people, and it's difficult to recover from. But life does get better, and you can recover!

Definitely consider counseling if you aren't getting it already. A professional counselor can be a very big help to your mental health - and remember that in knowledge work our mental health is our vocational bread and butter, so it's worth investing in :)

You know at some point in the last 20ish years, people really got used to the idea of free music. Once people get used to the idea of ‘free’, it’s like, good luck arguing against that.

I don’t think something like VSCode should be free, or a single api call on any platform, etc. Absolutely nothing should be free because people get too used to the idea of free. It’s a human failure.

> I’m not sure this is true either, but contributing food and housing for slaves is not in any sense paying them, but maintaining them as property, since food and housing is a necessary expense (they wouldn’t be functional slaves otherwise). Its more akin to maintenance on machines.

I can most fully agree with that last sentence. It's very much like maintenance on machines. But I don't think employers see as much difference between labor wages and machine maintenance as you do.

Certainly food and housing are necessary expenses, but there's a lot of room for interpretation there. You can make a business judgment about how well to feed or house your slaves -- or particular favored slaves -- in much the same way that one company might differ with another company over how much to invest in employee morale.

> I think what you’re getting at is that while their labor is compelled, they are somehow compensated for it.

It's a little more complex. Slaves can be compensated in numerous ways; one very common way in the American South was to allow them to practice sharecropping. That would be labor that was not compelled, but from which the slave was entitled to keep some of the gains, whether for direct consumption or commercial sale. (As opposed to ordinary labor, which definitely was compelled and all of the gains of which went to the landowner.)

This model extended to slaves who could provide skilled labor. Their labor was in general not compelled; they often worked as independent contractors, dealing with customers directly. Like the sharecroppers, they were entitled to keep a portion of their earnings, and the rest went to their owner.

---

An ordinary slave has some money in his pocket. It might not be very much, or it might be quite a lot -- a slave who administrates a complex organization (presumably for his master the owner of the organization) is a person of much higher status and wealth than peasants have, and in Mamluk Turkey the sultan was, technically, a slave. [1] Slavery isn't about wages or lack of wages.

Slaves are generally distinctive in three ways:

- Slaves are not free to leave.

- A slave's owner has the right to compel their labor by various means, even if that right is not exercised. (And as a corollary, an owner has the right to visit certain punishments on a slave for pretty much whatever reason.)

- If a slave commits a crime, the slave's owner is legally responsible for that crime.

Not all three are required; obviously the Chinese emperor would not be responsible for a crime committed by a eunuch. But these characteristics are much more typical of slaves than unpaid labor is. (Someone to whom only the first point applies is, for reasons not entirely clear to me, called "serf" rather than "slave".)

[1] The Mamluks were a caste of steppe nomads captured in slave raids, and constituted the military. To be eligible to be sultan, you had to be one of them, and you had to have been born free on the steppe, captured, and enslaved -- children of Mamluks inherited the caste status, but those born into slavery were not eligible to rule.

Why is that worse?

I very seldomly use threads for concurrency, it creates monolithic binaries that are hard to maintain, configure, and understand.

I much prefer a process based architecture with mmap'd shared memories for interprocess communications.

Ask HN: Feeling Lost as a Freshman, Should I Just Drop Out?
I'm a non-EU international student in my freshman year of CS in an university in The Netherlands, for as long as I can remember it's been my goal to go abroad and study, due to the poor quality of education offered in institutions in my home country (Malaysia) and of course to gain the experience of living abroad.

I've been doing well academically (>7.5's), up till my mental health could no longer keep me going. I had a little stumble when a project fell apart and in the last month I've been working hard to simply get back to it but it's been incredibly difficult.

It's been months that I've been here now and I've yet to see the inside of any of my classrooms, I've not met any of my classmates outside of my orientation group (many of whom have since left the university). It's incredibly difficult to find any motivation whatsoever.

The 'central loop' of my life consists of getting out of bed, into the shower, getting to my computer desk, working till the school days up to prepare a meal, clean up, watch some streaming content and back to sleep. Having lived this loop day after day, knowing the school work I'm doing has no real effect whatsoever, is even more of a disconnect from reality.

I'm afraid staying here will kill my passion for technology, not long ago I'd be extremely excited for the content being thought in my classes now, I was actually going through teachyourselfcs.com's curriculum prior to being admitted here.

This post is a little incoherent but I guess what I'm looking for is a little advice on how to proceed, as an only child, with a lot of money invested into by my parents, poor job prospects without a degree and rapidly deteriorating mental health I just feel lost.
I didn’t want to include this in the main post at the risk of seeming needy or job seeking, so I ask here do I have any chance if I leave now? The 'skills' I posses are rather limited in the sense of my depth of knowledge in them but I've decided to list them anyway.

'Languages'
Java - SQL - Haskell - JavaScript/TypeScript - Python - MATLAB

'Web Technologies'
Svelte/Sapper - HTML/CSS - Maintaining a domain / mail server

'Low Level'
Arduino (AVR Assembly and general electronics)

And a bunch of random linux knowhow, i.e. bash scripting, PAM implementations, containerisation etc.
