I wonder how well it handles or rejects syntax-level expansions. E.g. can the outer language produce half an expression for the next level? Do I need to worry about the common pitfalls of macros?

I hope this works out. C++ has been deliberately evolving in the same direction, e.g. using `if constexpr` for conditional compilation. Plus, since the C++ compiler is aware of both levels of the language, it can catch some errors even for compilation paths not taken.

But the C++ syntax for metaprogramming still leaves a fair bit to be desired. So I like that folks are still experimenting in this area.
Moreover, consumer items beyond a price point are both very well made and backed by long term warranties anyway.

Paying a bit more for a better item which can be repaired or serviced for a very long time makes it cheaper in the long run in my experience, because you buy it once and for life.

I love "overkill items for everyday life" point of view, but it comes with trade-offs for noise, ergonomics, size, replaceability and such. You can get a very good blade from Victorinox or Leatherman. If you fancy good steel, you can get a high end, forged German steel Victorinox chef knife and use something frighteningly sharp and handsome at the same time.

If you want a good heater, you can pay twice the price and can get a Fakir Hobby premium space heater and can use for 30+ years (we have two).

The list can go on.
Most of the times, it works flawlessly, other times it fails on some inputs. And that defines how well your old code will behave is what you are using it for, so this property is known at design time and if you go for reliability (you certainly should, but most people don't) you can know before writing the program if you'll need to care about text encoding or not.

Either way, a complete rewrite of the text handling functionality should give you flawless functionality. At this point in time, all the important ecosystems that use UTF-8 are almost there.

This is very different from the other encodings where a complete rewrite of the text handling functionality is needed just not to fail every time. That made all the important ecosystems that used other encodings to get almost there much sooner, but there was an important period when everything was broken, and the improvements are much slower nowadays, because when you need to fix every aspect of something, iterations take much more labor.
The hybrid approach of calculating loss with a physical system and then calculating the gradient using a model narrows the simulation-reality gap. The cost would surley be much, much slower training. If the physical process required, for example, heating and cooling an oven, training would take a very long time.
What's the point of posting this now? Pure UWP is practically dead. Microsoft has made most of the new APIs and GUI features originally meant for UWP available to all Windows programs through WinRT/COM. UWP is simply being absorbed into the wider Windows ecosystem. You only need to deal with the UWP sandbox these days if you're a masochist.
Is being a 'failure' entirely dependent on whether or not someone was successful in accomplishing some sort of goal? There are plenty of people that might be considered non-failures that successfully engaged in behavior that was/is abhorrent and detrimental to society. Wealthy slave plantation owners wouldn't be considered 'failures' in that sense of the word. To me, it doesn't seem like failure is a useful binary metric in determining the worth of a person.
I disagree that they failed to do so. It was left up to the states, as it should have been.
> Hacker news is holistically anti cryptocurrency.

First, your use of "holistically" doesn't make sense to me.

> ho·lis·ti·cal·ly | ˌhōˈlistik(ə)lē/ |
> adverb

> mainly Philosophy in a way that is characterized by comprehension of the parts of something as intimately interconnected and explicable only by reference to the whole: the damage caused by unethical behavior needs to be examined holistically.

> • Medicine in a way that treats the whole person, taking into account mental and social factors, rather than just the symptoms of a disease: he has been treated holistically for a heart murmur.

Second, are you characterizing the people on HN as being mostly or completely against cryptocurrency? This sounds like anecdotage. Remember, not everyone with an opinion broadcasts it.

Yeah that Uber thing struck me as false too. It was obviously a ride-hailing app and provided a superior service to what existed before. The self-driving thing came up later and was always a sideshow. I suppose it helped them raise money but it was hardly their "pretext to ignore all regulation".

It's a side point to the thread though.

I think NFTs will transform the concept of ownership

The current concept of ownership appears to be that if I own something, broadly speaking, that means people generally agree (and the state, and ultimately their monopoly on force, will back up) that I get to say what gets done with it and who gets to make use of it, and that it's not OK for someone else to take it away from me without my consent.

If NFTs are going to change that, I'm not sure I like it.
Yeah. I think these HN threads are either manipulated, or HN is full of idiots. Not sure which is more likely.

Cryptocurrency is maybe the most important innovation is human history.
A friend of mine paid another friend of mine $80 in BTC for a trip we did about 5 years ago. That BTC, never touched, is now worth $5000. At any rate, it's definitely volatile, because the asset class is still a small (but growing) potato in the grand scheme of commodities markets. One thing we can be sure of, it will never go negative in price, unlike oil.
"the fact that I can get better interest on US dollars by depositing stablecoins on some defi platform"..

There was this guy called Madoff. He was able to get better interest than the markets for quite a while too. Those stablecoins are not contributing to the productive economy. They're not being invested in machines that make new cars, clear carbon from the air, produce cheaper food. Nothing about cryptocurrency will solve housing or free time, because those are political problems which require humans to come together with a common aim - not, in the complete opposite example, people just wanting more for themselves by "depositing stablecoins on some defi platform".
That is not true. I create content for YouTube as my all the time job (and the jobs of my employees). I have no issue with self-hosting. The problem is that YouTube has the audience.

Isn't all currency more or less a "pyramid scheme" in the sense that Bitcoin is?

I wish we had more subtlety in our discourse. It feels like it's all either blind admiration or blind condemnation.

Bitcoin is trying to be a new currency. Currencies more or less operate on "collective delusion". I think many people scratching their heads at why Bitcoin is worth anything _are_ missing something, which is why any currency has any value at all, which is itself kind of surprising and unintuitive.

At the same time, I think it's fair to be a little more skeptical about what the value of a currency like Bitcoin is, precisely, and how much effort ought to be put into building it.

> They've completely improved ride-sharing and cab hailing within the whole industry, including non uber users.

They only did that in some places where there were poor Taxi markets (medallions etc). In places where you could hail a cab follow it and pay for it with your smartphone years before Uber, they did nothing. They didn't exactly invent that. They just said that because magic fairydust they could do that also in cities where the law said they couldn't. Which is kind of strange when you thinnk about it.

No, but I don't find it particularly low quality, either. Just not personally that interesting to me.
Yeah, but when you took away the money part and just looked at the technical idea of a distributed chained ledger with no central point of trust, that was cool. At least, it was cool to me. It seemed like it might go in some interesting other direction.

I still don't see the misinformation. I said, that it was "almost impossible not to give it to others". I said the virus was extremely transmissible. It is. With an R0 of approximately 5.7 [[1]]. I didn't say anything about when or how transmission happens.

There was a moment where we thought our daughter had the virus. It became quite clear how futile it was to avoid her infecting everyone else in the house. Fortunately for everyone, it was something else.

Just gonna sound like a hater, folks worship success. They will listen to anyone who made millions betting on cryptocurrency over any smart person who didn't and is "jealous" for missing out.

One mistake us "smart" folks make is thinking that investing is about understanding a system that's complete and smart. Most investments are not like black jack but more like poker where it all comes down to behavioral economics and psychology. Doesn't matter how stupid the actually game is, it's about the meta game with the crowd.

Plenty of tech folks making money in crypto know this, wallstreet going into crypto knows this. Most of us in tech are too autistic to play on that level. So focused on the correctness of the tech.

For the players it's a big casino and they know it. The lucky winners will be rewarded for having heart and playing
How does RAM break? How often does it fail?
I see more and more tweets and articles like this posted here on hackernews that echo the sentiments of the world economic forum on how they feel about cryptocurrency. Remember they are the very people that say you should:"Own nothing and be happy".

Second Life did this 3D virtual world stuff almost 20 years ago, and even managed to use real money with an exchange rate as well to do exactly the things you're saying are now new with crypto and blockchains.

Also for your other points - the games in this space are universally unfun to play with hardly anyone actually playing them; I can pay normal money to commission artwork; and I can use a zillion platforms that already exist to raise money.
If everything is considered ‘owned’ based on NFTs, and other stuff relies on that to verify ownership and provide services, then the government talking the physical land only gives them the utility of the land itself, and not the other stuff (eg. The ability to sell the property) - plus, the government superseding a fictional blockchain-backed real estate market is likely to cause a market crash.

Blockchains and NFTs make sense only when the blockchain becomes the source of truth, and it does solve real problems - it just doesn’t work for cryptocurrency when someone’s $1 could be worth 30 cent or 6 dollars in just a year. Nobody wants that amount of uncertainty.
The Mental Model FAQ
Fully agree. The current/legacy financial infrastructure is actually 10 times more decentralized than any DLT: DLT is the same software run on multiple nodes.
SWIFT in contrast is a protocol, that anyone can implement. So its hundreds of software teams, building and operating their part of the infrastructure and integrating with each other. The SWIFT protocol itself is maintained by the member organizations, anyone can bring in proposals.
The complexity of it does not come from technology, but the regulatory requirements which differ vastly across the world.

Yeah, all the problems of the world are due to bitcoin and cryptocurrencies. Embarrassingly, more than a decade in, HN is still struggling with it. I don't consider harmful, I consider it a godsend. Ten years ago, I knew HN was wrong, it will still be wrong in a decade.

Git is the most wildly successful and broadly useful application of the ~blockchain~ merkle tree data structure. It’s fantastic and here to stay.

The digital money angle? Eh it’s okay. Everyone loves a gullible population that prefers to be paid in not-money.

Eventually crypto will have to invent all the overhead and governance it was trying to escape. You know, so things like Musk’s little pump-and-dump the other week stop being possible.

For the downvoters: The original bitcoin paper explicitly says it’s using a merkle tree data structure under the hood. Same as that used by git.

Some background to it.

For laptop sized parts, semi-solid rheocasting,thixomolding is much cheaper than conventional casting on per part basis, and usually gives you superior fine features like studs, ribs, thin walls, and thus greatly reducing the need for final machining.

Downside is that semi-solid casting/molding machines are much more expensive than conventional ones because of powerful hydraulics, up to few times as much ($300k-$600k for making CE parts,) and the cost grows much faster than the maximum part volume. The alloy for them is also much more expensive than common aluminiums.

But on scales of consumer electronics manufacturing, material costs are minuscule in comparison to everything else, and the net shape capability is 100% worth the premium.

Both techniques will give you equally high material strength, but you will be paying much more for quality for conventional casting, to the point the cost advantage is lost.

Stronger low silicon alloys will need higher casting temperatures, and pressures to compensate for lower castability, and will also need degassing equipment, more expensive molds, and more extra equipment in general.

On the size of car chassis, I may bet the material cost will start to make a difference.

As a rule, you will need a lot more extra material to compensate for overall lower strength of cast parts.
When I say pyramid scheme, I don't mean it in the sort of philosophical way that you could apply to all fiat currency, but in the "OMG look at Tether" way.

Returns to Scale in Broken Windows
1. The investor put in money and receive a number of shares. There will be a document outlining how many shares the company is split up into (let's say 10 million) and how much the investor paid for their shares. Derived from that the company can calculate your share. You should ask about the total number of shares and if there are shares of different classes (e.g. founders might have shares that hold more power). If the company is intransparent I see that as red flag, at least with their earliest employees.

2. Options that can't be exercised have no value. If your contract says you can exercise them, or a percentage of them, after a year, then that's the earliest point to have value. But there's no open market to sell shares. Your contract might even say you can only sell them back to the company. And when you decide to sell there needs to be an agreed price. By my experience (see below) the company might not want to name a price, add delays, point to near-future investment round, lowball you. They do have value, you do have the right to exercise but the actual exercise might lead to conflict with the founders because it's often not in their interest. The younger the company is, the earlier of an employee you are the more potential conflict.

3. That's actually good. Some contract say you have to exercise when you quit, or after e.g. 90 days. But you might think the company is growing well, stock will be worth more in the future and are allowed to hold on to the options longer. It gives you a bit more power.

Story time: two years after joining an early startup I decided I want to exercise some options, like 10%, almost just to see how it really works. The founders were very reluctant. They didn't worry about me leaving. They didn't care about the money itself. But the sale would force them to write down what a share is currently worth. They were negotiating with new investors, or planning in the near future. The investors would ask what the company is currently worth and this number would have to be presented again to the investors. They worried so much I got a cash bonus for NOT exercising options.
You need to have done the interview to get the offer.

I'll offer my two cents in case it gives another perspective you haven't considered. The meaning of voting on HN is far from obvious. Various people downvote for different reasons.

Maybe they are unimpressed by your comment, maybe they disagree with it, maybe they think it is inappropriate somehow, maybe they don't like that you plugged a particular cryptocurrency, or something else.

In any case, I recommend not worry about the votes, up or down. At times, it can be helpful to see if what you are writing is perceived as useful, if you can take the feedback in that manner without taking it personally.
