I fully understand that, but sentiment can change. It's disingenuous to say it won't change in the future because it hasn't yet changed.
Here's an awesome diagram of all tracked space debris from 1959 to 2021 showing the constant cleaning by drag happening at lower orbits. It's the higher ones we really need to care about.

Plenty of exchanges out there, so I would say yes.
Actually, I think a large portion of the market has realized these are fake and just don't care. As long as everyone treats them like they're real, they're real. The risk is some sort of run on the bank where everyone tries to cash out to fiat, but I can't imagine what would cause that at this point.
Quick caveat, I'm extremely shallow in my knowledge of any of this:

>How would you prevent the puff of gas from diffusing into nothing?

My thinking about this is that at low concentrations the gas would maintain a largely ballistic trajectory and not be subject to typical diffusion properties. Would require a purpose-built accelerator to condition for 'beam' coherency. Not sure how well that scales.

> Where did you get ~35km/sec? ISS orbital speed is 7.66 km/s and it only gets slower the higher you go up.

Major brain-o.

Ultimately I think we're on the same page of 'kinetic deorbit', just a function of what is actually feasible.
Again, the whole problem is that the bad actor can pass off their stolen bitcoin before anyone knows its tainted. So it doesn't matter if you didn't use a mixer, if that bitcoin ever went through a mixer it could potentially be a live hand grenade. People could just mix large numbers of bitcoin periodically so everything is suspect.

You're not solving the problem, you are just introducing new problems that affect other people in the hopes that the entire system becomes unworkable.
I have had a Laptop 3 for a while and haven't had most of these problems (I'm frequently using a bluetooth xbox controller + airpods pro + wifi on it). The ambient brightness thing is so goddamn annoying though! It's not an MS thing specifically (I know Dell XPS has it at least, too) but it is just the absolute worst.
YouTube is? Or we as a society are?

The world of Fahrenheit 451 didn't arrive that way in a day, it probably took decades.
I don’t think it is a new phenomenon in the language. I associate this with Northeast US accents and many British accents. It may be that regional accents which use a glottal stop for this pattern are leaking into younger people’s accents around you simply because YouTube and TikTok are making less common accents heard more widely.
It poses problem for native speakers as well. After all, there are no Spelling Bee competitions in France, or Germany ... or anywhere.
Apple trusts Phobio for its trade-ins, but maybe you should think twice
I assumed OP implied they device was used very rarely.
Note that this bound is not proven, it is for now a conjecture. There are solutions to Einstein's field equations that would violate it ('Wheeler's bags of gold', different volumes contained in the same surface area, with different entropies, possibly greater than a black hole's), so it remains open whether the holographic principle holds.
Not a popular opinion here but selectively covering up research is a play straight out of the Communist Manifesto. This sounds more like concerns over the spread of hacking intel, but it's worth noting yet another example given big tech's selective censorship over the past year.
Unlike Ethereum, Bitcoin addresses are just a hash of a public key. The sent Bitcoins are unspent outputs that you can selectively (depends on the wallet) decide not to use.
I think a more relevant metric would be the velocity of the Cypto market rather than the total value of the number of coins out there. Since Coinbase is taking a % of every transaction, if you send .1 bitcoin once then they get .5% of that. But if you send .1 bitcoin 10 times then they get .5% of 10*.1 (not the real % obviously).

I've seen numbers around 250k to 350k transactions per day for Bitcoin and more than 1 million for Ethereum. So if Coinbase can capture a decent percent of that market then you're talking about tens of millions in revenue per day (if not more).

From a quick search it looks like Coinbase had around $1.8 billion in revenue in the first quarter. That could/should grow along with popularity of crypto in general.
Also there is a good question is there some limit or ratio of tainted coins that would be considered non incriminating. Or if there isn't would single satoshi taint all coins? If there were wouldn't dilution of funds be possible? That is wash them by sending to wallets with enough funds...
Ask HN: What virtual phone service do u use?
Hi,

Is there a virtual phone service from which I can buy a phone number? If so what do u recommend?

I simply want a number that I can use for WhatsApp texts. I don't need it for making calls or SMS (except in the event of WhatsApp number verification) — nor do I need a data plan.

I have looked into several eSIM providers and all they seem todo is bundle services that I have no interest in.

What do u guys suggest I look in to?
Hard disagree. User stories are a great pithy way to describe a high-level need with a supporting reason. They usually take only a few minutes to write quite a few and in group exercises we've been able to generate many very rapidly.

The task/ticket however (and work to be done) is separate and derived from the user story. This can dive into architecture choices, _why_ this solution and _why not_ that one, specific implementation details and steps to achieve those.

Both types have their pros and cons and work best when used together because they serve different people and different goals.

Don't write something off just because you saw a post make it to HN p.1 - try things out for yourself and decide based on _your_ team and _your_ needs.
I also don’t care about companies that don’t make money.
> IANAL, and I don’t know if dissemination is somehow different from creation in defamation cases. I expect it has to be - otherwise “Mr. X is a pedophile” can be illegal while “I heard that Mr. X is a pedophile” isn’t. Which seems dumb if one’s intent was to make defamation illegal in all ways.

It is different. Opinion is also exempted. I don’t think that’s dumb at all. Otherwise it would be impossible to report on a controversy without risking a lawsuit.
I am curious if a similar mission could be undertaken to retrieve a long lived satellite from orbit and bring it back down to Earth in one piece. I imagine there could be learnings from seeing how different materials and structures faired in space over long periods of time.
First rule: trust your colleagues. If you think you’re a good developer, chances are your colleagues are good as well (otherwise they wouldn’t be hired in the same company as you; they wouldn’t even be in your same team).

Second rule: don’t spend time in small details. This usually means: syntax, variable names, line length, test coverage. If you care enough about this, then install tools that verify this automatically when opening pull requests. Variable names: I know, this seems important, but bad variable names doesn’t necessarily mean bad code (keep reading).

Third rule: think long-term. This is, is the code under review easy to maintain? It’s not that subjective: how many files are being touched? All of them just for one feature? Smells like we need to refactor something else before working in that new feature. Are good abstractions present? This usually means you know a bit about the domain model and: no inheritance, dependency injection (I’m not talking about containers), and well defined interfaces.

Rule zero: no bugs (or at least no evident ones).

Regarding looking at the code at once or going commit by commit: none is a good way. Start examining the client code (or tests, sometimes) and go up to the core code (the one that has less dependencies). Usually the client code will tell you if the feature has a “good” architecture.
Qualities of a Startup Founder
It's not that it enables more, it's that the AI is harder to fight and easier to excuse.

Just like when a clerk tells you "The computer won't let me."
The main issue I've found with Agile is that in the two iterations I've seen (one BigGovCorp, one late-stage startup), the team ends up with a situation analogous to audience members directing a movie. You can collect a list of audience requirements (explosions, romance, Chris Hemsworth, a string quartet, Garfield) and then your devs can string them all together into a single package that technically works, but there's no rhyme or reason or predictable trend of what the software is.

Furthermore, as other commenters are mentioning, once you start focusing on your ticket system, developers feel "done" when the tickets are done, rather when they believe that what they've implemented is actually a functional, conceptually consistent piece of software.

I don't think there's any solution except "get the right people and then try a bunch of crap and stick with whatever gets the best results measured against the goals of leadership."
And why would currency users even bother with it? If I receive a payment for something, I don't feel the need to pretend to be the police.

As someone who works closely in the field of Apple security issues, I strongly agree with your first statement--the narrative on this topic is often weirdly pro-Apple as this device effectively already had a backdoor that anyone could have used to get into it with nothing more than Apple's firmware signing key (an issue which was only addressed in later versions of this device)... Apple claims that the key wouldn't have been useful to the FBI without their expertise to help, but I can attest that that is BS as forensics people in the jailbreak community had maintained alternative ssh-only firmwares that provided the exact required PIN-code brute forcing tooling for years--but the rest of your comment (the chosen defense of your thesis) is sadly much weaker than it thereby could be because the FBI actually covered why iCloud Backup wasn't helpful in their court filings: if nothing else (there is a bunch of explanation of why a "forced" backup wasn't possible that is maybe "extraneous"), the device hadn't been backed up for months before the incident (with automatic backups turned off) and there is data they wanted (if it had been there) which is not part of a backup (specifically various caches).
The electronics on-board will degrade over time due to radiation effects and the batteries will at some point hold no charge. It's probably cost-effective to just send up an MEV to cover you for a few years while you decide if that satellite actually needs to be replaced. Commercial GEO satellites are not as popular as they once were. The new thing now is launching constellations in LEO for dirt cheap (a la Starlink). You don't need to keep LEO satellites up there for 15 year missions because they can easily and quickly be replaced. Planned obsolescence is the future.
Why do you think the BOM cost should have any relation to the selling price?

> You can slice this any way you want, but there's not really an excuse for an all-digital synth to increase in price like that

Adjusting to market bearing price seems like a good excuse to me.
I'm not a desktop or a ui engineer by trade so I don't understand the contention with Electron. I know slack uses it and _seems_ to work fine but I have heard similar phrasing around "sorry for suggesting electron" and I'm curious to learn more about the cons of electron.
I think is a very valid criticism, paying $1500 a year for a static site with a like button is odd. Hosting this site on something like Netlify would literally be free while also satisfying every other requirements save for the heart button. Even the Netlify pro tier would only be about $200 a year for a small site.
Atomic swaps were possible way before Uniswap and the DeFi craze. Liquidity is another issue for 7.5bn though.
Someone has to come in and make it supported. Adopting nlvm isn't going to magically make it easier.

The reason it's easier in Rust is because someone that's passionate about WASM came along and did the work up front to document everything and make it as simple to compile to WASM as possible, the same is certainly possible in Nim, just need someone to put in some work :)
The threat models from 419 (Nigerian / advance-fee fraud) spam are:

- Individuals are subject to a fraud risk.

- Trust in the medium as a whole is decreased.

- Risk of false-positive spam flagging increases, decreasing legitimate message transmission reliability.

- Fraud will continue so long as costs of operation are lower than rewards.

Economic spam, in a word, follows an economic model, and is subject to economic attacks. The notion of some form of "email postage" is one ultimate form (thus far both impractical and widely rejected), but other "increasing the costs of business" have had ... significant if not perfect ... results in limiting the activity.

The calculus for political propaganda is vastly different, with the rewards of even a marginal success being tremendous, and the resources of antagonists being prodigious. It is very much like war, that most costly of economic activities.

It is war.

It is information warfare, rather than physical warfare. The weapons are messages, messengers, channels, informants, and audiences, rather than missiles and knives and fire and water and chariots (or tanks or helicopters or bombers or ...).

But Sun Tzu wrote of both types 2,500 years ago.

Unfortunately, the fundamental architecture and premises of a major contingent of participants fundamentally enables the attackes presently being conducted. (This is of course something of a tautology: if a terrain is fundamentally favourable to a specific mode of attack, that attack will tend to be employed, successfully, on that terrain.)

While I agree with the overall decision, this hurt to read:

> SInce it's closed-source, none of that matters to me. But if it was open, folks would want to grab it to use in their own projects. I'd feel a certain responsibility to make sure that it works well, or at least to make sure that its shortcomings are well-documented. And I don't want that responsibility right now.

I see this argument over and over. I see it in academia as an excuse not to share code and data. "I haven't cleaned it", "it might not work for you". *I* will decide if it fits *my needs*, and if it doesn't I don't see how it's your fault. Code is better than no code, I always have the option of not using it.
Ok so use it to pay the fee, returning the rest.
I'm a fan of tfenv for this; it's really easy to use and makes it trivial to pin each stack to an exact version of TF.
I think "worse is better" is more about keeping things simple and composable than necessarily being the first mover.
I haven’t thought deeply about this but here are some things:

- starting martial arts and then boxing. As a skinny guy it’s nice to know that you can take on most guys even if you never have to do it. This confidence is very helpful even in business situations. Being in shape also helps with the ladies...

- yoga and meditation

- traveling alone through India and other parts of Asia. Once you have survived that there aren’t many situations that feel scary.
>User stories evolved over twenty years ago as a way to communicate what a customer wanted into product requirements that a software team could deliver. ... Customers are tech-savvy enough to articulate basic product requirements

HA. Sure. 20 years ago Customers were dum-dums, but today Customers are tech-savvy.

>issue should describe a task with a clear, defined outcome.

The point of user-stories is that the implementing developer also has a brain and is able to contribute to the solution. So a user story is supposed to communicate the problem the customer is trying to solve so that the specific solution can be derived collaboratively. Nothing is worse than writing a task to turn a developer into an automaton.
No, I fix my machine from SystemRescueCD if anything go awry.

I wasn't thinking of “resuming installation” so much as “accidentally made my machine inoperable”, which becomes apparent when rebooting after the installation.

If the machine were not made inoperable, I would simply use the web browser that comes with the live medium of the installer.
Well said! People often ask me for my founder perspective, and I always say the following at the end of such meetings - This is just my point of view biased by my personal experiences. You should talk to more people and hear their points of view. And in the end you should make your own decision.
If this were actually true, Coinbase would not need to exist with a market cap of $100B.

Even if it just restates the Standard Model from a completely different starting point, I think it's incredibly interesting.

Also remember it took decades before all of Einstein's 1905 predictions had been commonly accepted.
I think my argument focuses more on pragmatism.

As an example, I had a database I had to investigate with just ... nasty data. Really filthy. Multiple things compounded into a single field, and so on and so forth. One field in particular I needed to decode for the process. So I tried a regular expression and it mostly worked on the first ten. But then it failed.

And I looked at the case that failed and scanned for other incidents, and now I had two expressions to try. And I looked at hundred instances, and it mostly worked, but there were some exceptions.

This went on until I had ten sets of "rules" to cover all four million of that field. It's not elegant, it probably isn't the fastest, but it starts at the bottom and works its way forward.

It's easier than you think. Just five organizations command >50% of hashpower[0]. I don't think it's likely to change soon but it's not out of the realm of possibility, and it's not even the most decentralized cryptocurrency in terms of difficulty to enforce new network rules.

If your first thought when making decisions was "what won't send me to prison" you probably wouldn't be engaging in criminal enterprise in the first place.

Most people who break the law do so because they either don't consider the consequences or accept the rewards as justifying the risks. And plenty of criminals go to prison because they judged wrong. That those who are successful for long periods of time buck this trend is just survivor bias.
The NYSEs parent company Intercontinental Exchange Inc (ICE) is worth 66.40B. Today's IPO puts Coinbase at 100B+. The NYSE has been in operation since 1817. Coinbase has been in operation since 2012. The value of all crypto is < 1T. The value of the US stock market is 50T.

Trading fees in the crypto-world are getting more competitive as more established players support crypto. I don't see a defensible market position here, let alone established track record or strong potential for growth in future earnings.

This is all feeling very dotcom bubble 2.0.

Pros: you run your web app as a local app without reprogramming your app.

Cons: you are literally running a web app in a browser and not a native app.
Well I haven't tested it but I have seen that when I open WAW people suddenly start pinging me. So I assume this is why.

Either way it's not a big deal as it hides your real status either way.
>> launch stuff to very low orbits.
>>Even if they go offline or got hit, the debris would have a very restricted lifetime.

That approach can help, but the problem persists. Lower orbits are much smaller than higher orbits. Focusing megaconstellations into a narrow 100-110km band is asking for trouble. The kessler syndrome could occur in a very narrow band, quickly rendering even short-lived satellites uneconomical. The narrower the band of orbits, the more likely and more aggressive kessler becomes. It is one thing to loose a few sats every year, very much another to have your entire constellation wiped out every year.
But that wouldn’t make those bitcoins theirs legally, would it?

Doesn't the Coinbase treasury create/hold un-issued Coinbase shares? Do we know they didn't sell any of those?
As someone who does research in biology and therapeutics, it seems to me that Alzheimer's research is such a dismal field. We don't have a good idea of what causes it, not only do we not have good animal models, we have misleading animal models which reflect some of the traits of Alzheimer's but nothing translates to humans. There was this mouse model they made which developed these plaques like in Alzheimers and they found they could clear them with brain stimulation pretty well - but trying it in humans there was no effect.
Depends on what you mean by inferior. If you mean inferior as in quality, then your link doesn't support you:

> It refers to the argument that software quality does not necessarily increase with functionality: that there is a point where less functionality ("worse") is a preferable option ("better") in terms of practicality and usability.

It's a rephrasing of KISS. This isn't about getting something quicker out the door.
> Once downloaded, the JS and wasm bytecode must now be parsed. The JS interpreter starts parsing and running. Meanwhile the wasm code is pre-compiling into native code so it can start execution.

I thought wasm's format was specifically designed so that parsing and compiling could be performed in a streaming fashion, so that you don't have to wait for the download to finish.
The proportions remind me of another somewhat common space-related misconception, which is that rocket launches are big polluters.

With each launch emitting roughly as much as a single commercial flight and typically around 100 launches happening globally per year, even a tiny change in the tens of millions of commercial flights per year has a far larger impact on emissions than launches will for the foreseeable future.
