It was never in any danger of becoming the future of money.

The entire power of a modern market democracy rests in the ability to control its currency. If you remove that power, the state itself has no legitimacy. Bitcoin was never ever going to be blessed as an alternative to the USD, no matter how much sense it made on paper.

Bitcoin is a pure sentiment asset. It rises when people think it should rise, and falls when people think it should fall. The value is neither reflective of productive work or a legitimate arbitrary power. It was and is a beanie-baby/baseball card economy and it will never be anything else.
How is that going to work?
AES-GCM encryption in JavaScript, decrypted in C#
Which is obviously evidence of a complete and total failure.
Alright, so you can create an IDE in the browser, but, what else? I'm just not seeing the value in running servers in your browser. Presumably, most sites will still need to connect to a remote back-end services to get at data and whatnot, and that back-end isn't going to be running locally on a customer's web browser.
Yep, this is true. In fact, we already improved performance by over 25x by optimizing algorithms in JavaScript. As covered in the blog post, this rewrite was motivated by more than just performance and does include algorithmic improvements as well. We figured that while we were rewriting we might as well also use a language with more predictable performance traits. But, your points about extensibility does still stand, and that's something we hope to look into more in the future.
Even worse, they think they are better than other people because of their money.
I used Qualcomm brew in grad school to create an accelerometer based app to detect falls for senior people. I remember the first time it detected a simulated fall !! I was new to such sophisticated phones and it felt like an amazing achievement. I remember talking to a Qualcomm engineer who helped me with the internal API and the whole setup.
Fun times!!
So the login credentials for your email (and thereby the possibility to reset all your account's passwords) are not stored on your computer (on disk or memory)?

The least useful thing for malware to do is to render your computer unusable. As that would prompt you to reinstall it or investigate the cause.
A single bitcoin transaction uses roughly 707.6 kilowatt-hours of electrical energy–equivalent to the power consumed by an average U.S. household over 24 days, according to Digiconomist

> Cryptography actually is needed for safety more than it is used by undesirable people to commit crimes!

This is actually more because criminals on balance tend to be too dumb to hide their traces than because of any demographic truth. There are a lot of criminals.

Focusing on "crypto" is, I think, a forest for the trees argument. Look instead at anonymity for evidence of where this kind of thing goes. Put up any reasonably anonymous forum where people can interact without their identities being reveals (which often includes, but doesn't always require, some kind of crypto protocol). Within a year it will be filled with criminals. Minor criminals like drug dealers. Worse things like market manipulation and fraudsters. Weapons sales. Black market rings. Revolutionaries of all sorts and sizes. Child porn. Mail order brides and other trafficking trades.

Seriously, run a Tor exit node for a while and see where this goes.

Your neighbors in your imagined "safe haven country for cryptographers" aren't going to be who you think they are.

I spent .2btc to buy a $50 domain name at one point around 2013, that I only used for a year or something. Woooops. But hey, I figured, the future of money, let's do it! Oh well.
What are some good books to learn more about this? Thanks.
This is an opinion piece about the volatility of BitCoin based upon its wild fluctuation due to some tweets by Elon Musk.

It's biased because it's an opinion piece, but do you have an actual counter to that main concern?
Same goes for GitHub. We took the most trivially distributed and self-hosted technology ever written and converted it into a single point of failure.

We software developers as a profession seem to have cultivated an almost active distain for anything resembling long-term thinking.
I’m 46 and have never been in a fist fight. Neither have most of my friends of similar age, as far as I know. I’ve lived in Norway for most of my life. Based on what I read in Norwegian news (I no longer live there myself), it seems that fist fights and other forms of violence are far more common among teenagers now than when I grew up.
The situation is different, because a CPU is by definition an interpreter. It does't perform code transformation, at least not at a higher level as a compiler. The CPU only looks at the next few instructions and perform them. A compiler, however, is responsible for taking a large coding unit and produce a transformation that is efficient. That process requires thinking about what is invalid code and operate on that.
Same here. Not exactly "not" care, in the case of unfair / anti competitive treatment. But in the grand scheme of things I am mostly fine.

I have a problem with Apple dictating their World View on me. May have been fine if they were apolitical during Steve Jobs era. But modern days Silicon Valley does not allow anything to be apolitical.
Ask HN: Cryptocurrencies – POUW (proof of useful work)
That topic is bugging me for a little while. Anyone who follows me (probably 0 people ;-) ) knows already that I'm not a fan of cryptocurrencies. And I'm not gonna dive into that here. Instead I'll try to solve one of its issues - it produces CO2 for "nothing". All computations it does is actually worthless, just bunch of bytes that people find precious itself.

So here is the idea:

Lets say we have a computational problem to solve and limited resources to solve it. The task would be to get as good as possible result for the problem within these limited resources. And every progress (getting better result from previous) would be gratified with "hash" coin based on proof of useful work.

Lets give a practical examples:

We want a video codec and best possible image quality on limited bandwidth, limited computational cycles on "virtual machine", limited code size and limited RAM resources. Library of wisely selected videos would be a reference for measurement of image quality. Every improvement in overall quality would be gratified with "hash" of the code. As long as final result fits within limited resources the algorithm of improving would not matter (machine learning/genetic algorithms ...) and be a subject of "manual" earnings.

Nearly same would be for audio codecs.

And then we would go for other important problems to solve for humanity - treatments for cancer, objects and voice recognition and so on...

What do you think about it? I will call it POUW (proof of useful work)

Someday, I'd like to see Wasi-based webassembly containers. It'd be awesome to spin up a sandboxed shell with file access in a webpage.
I don’t see how this is a serious concern, even if they do it. I would just consider it part of the price of the service.

It will be interesting to watch Apple lean hard into privacy as a feature. It is a smart play given their position in the market, and fits the current zeitgeist but it does seem to set a bar that Apple is going to have to clear going forward. People like privacy, but if Apple is perceived to be acting hypocritically (as in we should watch what is done with iAds and app store advertising) then it could really come back to bite them.

I had AKG headphones. I noticed a difference when noise cancellation was on, but there was a weird humming sound and they didn't work very well for me. Also, they're very bulky and you can't wear them while sleeping.

> With white noise and earplugs as well, I literally can't hear a baby screaming.

That's one benefit of headphones: if the earplugs aren't enough, you can do earplugs + headphones for ultimate noise-cancellation.
This is for businesses, not individuals.
There are stablecoins on top of Ethereum. Some are backed by off-chain bank accounts, others are based on price feeds and on-chain derivatives over ETH.
Yawn, i suppose they never heard of second life
My previous company had IRC as a backup in case their primary form of communication goes down.
You get the benefits of advanced communication systems with the ability to continue to work in an outage, and while it would be nice for everyone to have IRC, only ops folks really need it to sustain operation.
Yea, what I don't understand is how something like using ETH to buy another coin should be taxed? I totally get converting it back to dollars and calling that capital gains but trying to tax conversions from one to another seems nutty to me.
Lets walk through what you are saying

"I don't need a relationship".

"I am entertained enough therefore I don't need a relationship"

"I cant get aroused anymore. I have theories about why. Its humiliating/anxiety inducing. And therefore I don't need a relationship"

Since everything hinges on what you think a relationship is, its crucial you clarify what it means to your first.

This is super important.

If you don't have a good understanding of what something is, how can you want it?
Could you point us to an introduction to how operating system concepts get mapped to browser concepts?

It sounds like each native binary gets compiled to a WebAssembly binary, but how do they communicate? How are the network and file system implemented? Are parts of the file system persistent? How does a system call work?
My conspiracy theory is that cryptocurrency was invented by the CIA to destabilise the Chinese financial system.

Arturia Minibrute 2 and Drumbrute. AKG studio headphones. Got back into music last year leaving it behind as a teenager. For having fun, they're the perfect synths.

Yamaha C40 guitar (and weekly zoom lessons from a real master musician) was best value for money nylon string guitar around.

Returning to making music during covid was a lifesaver. So glad I learned the basics as a kid.
It is certainly more satisfying, I'll give you that!
Start your company with friends. Make something you all think will be cool. Starting a company with friends has risks, but so does anything worthwhile. It also has lots of upsides, like, you can trust them.

It sounds like you are trying to over optimise before stating. eg. worrying about what books to read, or about having a business plan and a financial model. These are distractions and they'll make you feel overwhelmed and not ready. I started my business with friends in college, it's still going 9 years on, and we did none of those things.

If you build something that's useful and you find people to pay for it, everything else will figure itself out in time.

Go to the git repo on GitHub, check out the code, go to the first commit, and see how many times the word “Poker” is in the code base.

Bitcoin was simply designed to be an in game currency for a poker game, but the narrative has been co-opted by so many people that it’s become something else.
Isn't this already required, sort of? AFAIK you have to report fiat transfers exceeding $10k. If you're cashing out at an exchange, and you sell $10K of bitcoins and then transfer to your bank account, that transfer would have to be reported. I suppose this requirement would cover crypto-to-crypto trades, but most of the volume aren't on US exchanges so I doubt this would do much.

edit: misunderstood FINCEN requirements, only cash transactions over $10k have to be reported
Just like this thread.
Can't stress this enough, especially the hyper heat models: caulked compressors (very high pressure) with phase control injector, not only it runs at very low temps but the performance and COP is linear down to -15C.

Insulation matters more with heat pumps, especially ceiling for cold starts (for descending heat build up from the top) as low temp air heating is not as radiative as IR from traditional heating appliances, or the conventional oil radiators that move air passively.

CO² heat pumps are less impacted due to the much higher air temperature but they are very uncommon for split system (dangerous), and usually used for water heating in AIO unit in a basement.

Had a house electrical failure recently with solar, ran one 18k BTU unit for 60m² on a tiny 5hp Diesel generator sipping 0.4L/hr. (2-4L for Diesel burner in comparison)

These models need proper installation as they use a synthetic proprietary lubricant compared to the commonly used mineral oil, moisture or contamination during tubing installation is a big deal for twin rotary compressors which may reduce service life.
Vine had the talent and the creative editing down. Many of the biggest YouTube stars started with Vine. World Star Hip Hop vine compilations were incredibly culturally relevant. They fumbled the bag, so of course those in charge would look to blame it on IG. Did IG have an impact? Sure, but this type of content never took off there. If IG really killed Vine for those reasons you listed TikTok would have never happened.
They "secure" the country by exploiting vulnerabilities and leaving everyone else in the dark. They see the world as just a game between them and other foreign surveillance institutions.
It truly boggles my mind that this discussion (linked in TFA) played out the way it did. In my mind it's 100% not okay to (by default) optimize away a check for integer overflow. I've never really written in C (or any unsafe language) before so I had little context for the types of traps C sets for developers. Based on the responses of the person who presumably implemented the optimization, it comes as no surprise that C is so dangerous. After reading this I hope I never have to use gcc.

I dislike how UB is used where unspecified would work.

For instance overflowing arithmetic is well specified on every architecture - the behaviour may be different on say sparc vs an hc12 vs x86, but on any of those architectures it will always be the same. Yet compiler devs have instead decided that it is undefined and so can be treated however they like.

There are so many of these UB that could be unspecified that it’s absurd - UB should be reserved for when there outcome is not consistent - UaF, invalid pointers, out of range accesses, etc
It could have been over a long period of time, more than an hour. Im not trying to spread misinformation, ive just "ruined" (I still ate it) a dish before, or imagined it.
Same here, it really put a spotlight on my mediocre endurance/general fitness level despite my best efforts to get out everyday for a bike ride.
When there’s a currency that has a fixed price and is cheaper than visa to transfer and is instant, I’ll be on board. Otherwise, what’s the point - other than making money?

I’d love to use a stable coin for micro transactions

The shielding was just a pice a plastic hanging from the ceiling, not some kind of box. So the cashier was breathing the same air as everybody else.
Okay, then let's rephrase without a code example: The implementation-defined behavior in the assert should produce "true" if and only if the number printed for x+100 (also using implementation-defined behavior) is always larger than the number printed for x.
Fair, this isn't reddit.

To explain the derision, I don't think the GP makes a good point at all, as crypto-adherents pre-suppose that there's a common acceptance that blockchain currencies are an internet-level breakthrough.

Linked lists are useful. Merkle trees are useful. Blockchain currencies haven't so far proven a single use case they perform more usefully than existing systems.

All that the ICO craze, the NFT craze and the De-Fi craze point to is that this is a solution in search of a problem. The only reason any of the crypto-based versions of those existing concepts (IPOs, collectibles, credit) have been able to accrue funds so far is due to fraud and mania.

De-Fi could someday become useful if someone figures out a de-centralised way to handle unsecured credit, but how do you include trust in an eco-system that is based around a lack of trust? Even if someone solves that problem it won't be because of crypto, it'll be because of whatever novel idea they come up with to meet that specific need.

Anytime a bitcoin video ends up in my YouTube feed I feel like I'm being offered quantum physics lessons by Deepak Chopra.

Anyway, that's why I agree with the alchemy comment.
reMarkable 2 e-ink tablet: I was on the fence for a long time on this, but I've been using it almost daily for 4 months now, and I absolutely love it. The logical part of my brain thinks it's quite pricey compared to an ipad or rocket book (what I used before), but I love having something that is so close to actual pen and paper that never runs out of space and is easy to sync to a computer.
There’s this guy on YouTube that does very detailed unbiased reviews of stuff (mainly tools) - Project Farm. He picks a few items within each category and does a bunch of (rigorous, scientific and very thorough) tests to quantify performance and test advertising claims. I still don’t take his recommendations as gospel, but it does give you an idea of how the particular item works and behaves and what to look for when in the market for something like that. Far better than others that think unboxing and commentary equals a valuable review.
Still pretty hyperbolic. It's just as likely that these work around Intel-specific landmines that couldn't function anyway else without violating Intel's IP. Either way, it's a Windows + AMD driver thing, not baked into any Ryzen CPUs.

Your guess as what it works around is as good as mine, though.
I used Ysplit before they launched and it was a great experience. While they do ask for a lot of account permissions it was probably necessary to execute on the automatic payment split features and not having to venmo request my roommates every month was totally worth it.
So far. Individuals will eventually be included, considering currency reporting requirements apply to them.

There’s still a middle man - the blockchain. If you truly want no middlemen you can barter.
800v adds some complications, if the pack is 800v you need a boost converter to charge from 400v or the pack needs to dynamically reconfigure with contactors or something.

On the Porsche Taycan which has an 800v battery you have to pay extra for full 150kw charging on 400v because of the voltage booster cost, the standard booster only allows 50kw and there is some loss in the conversion you will pay for.

Same issues if you go the other way and have a 400v battery with 800v charging except buck vs boost.

800v chargers can't be fed directly by 480vac which adds complexity and cost so there are very few at this time I believe, most chargers will be 400v and limited to 150kw anyway.

800v is probably the future but its kinda chicken and egg right now, I see why they went 400v.
why do you want to spin up a shell with file access in a webpage?
What about this is "native"? The page says it is "running natively" but also says "All code execution happens inside the browser's security sandbox".

Is wasm in a browser somehow considered native now?
Thanks for tip. I didn't know about this, I will look into it soon!
I think that's a fair conclusion honestly, though the cynic in me does want to point out that people do integrate their work against slack and that is difficult to maintain in parallel.

Netsplits are mostly a solved problem these days, both with increased reliability of the internet and with network failure proxies like RobustIRC (for the linking protocol); and I remember fondly the times where we had a single IRC instance for all of our company (which had people working across: Thailand, USA and N.Europe) without issue.

But, yeah, I think what you said is completely fair.
Same thing happened to me. Times New Roman font no less.

Nice downvote for looking up a simple legal fact, to address the misleading impression from the GP that an individual person holds the domain.

Perhaps this will be downvoted as well because the childishness is strong on this issue, but for the benefit of anyone who cares, the parent comment is at least technically correct (the best kind of correct).

The domain at the centre of this controversy is owned by an incorporated non-profit association registered as a company limited by guarantee, not by a "someone".
There are free vsts you can use instead of pianoteq as well.

These are all issues a compiler could insert checks for, saving you the time to do it manually, while trading performance for security or correctness.

C doesn't trade performance away, so if you'd like to pay the price of these checks, it's on you, the programmer to add them in. C programmers have to put in extra effort to make the executables safer and output correct results.

Other languages trade off performance for safety and/or correctness. The programmers using them have to put in extra effort to make the executables run as fast as they do in C.

Ultimately, programmers tend to make rational choices, and the stockholm syndrome mentioned above is really just C programmers dealing with the consequences of the trade-off they made by using C.
Also anyone who questions the panacea of BTC is labeled as a peddler of 'FUD.' Very much a cult like mentality.
Pretty sure racism is prohibited on hn. This should be flagged.
I can't think of a time where the internal IRC server where I work went down. Netsplits shouldn't be an issue for that particular use case.
>it's always funny how Apple......

This has been explained multiple times. Xbox is a specific gaming platform. iPhone is a general computing platform. Where all kind of business from different industry ( Not just Games ) using Apps ( or anything connecting to the internet ) are relying on it in the modern society.
Even before Notch left I'd say others like Jeb or Dinnerbone were more commonly known in the Minecraft communities as they were more active in the community & posting about upcoming things.

(then of course Notch went off the deep end and most communities rapidly began distancing themselves from him...)
You realize that with a NSL the US government can compel Google to disclose information on anyone and that the contents of NSLs are completely secret, right? Oh yeah, and Google operates globally and no one really knows what arrangements they have with the various governments around the world.
I (native German) realised a similar thing happening because I tend to use some syntactical features that lend itself naturally to Germans, like use of "whom" (corresponds to German 'wem', but 'wem' is pretty standard German and 'whom' is hardly used in colloquial English).
