To be pedantic, it actually seems pretty likely the first stage could have reached LEO. There were no issues at all on ascent, and it has the fuel capacity. At one point Elon was talking about possibly testing this.

But they decided not to do this, because their first priority was to get it to land, and they don't envision LEO launches using only the first stage. That will be in conjunction with the much larger second stage.
Sounds like a set of training wheels. Helpful for those begging to learn, but extremely limiting if you don't learn to take them off once you have the basics. I can definitely see the benefit of such an application, but the risks are also quickly apparent. Looking at it from one level higher, I think I would be in favor of such an application because those who don't ever take the training wheels off will, on average, gain more than had they never had it while those who would be held back by it are likely to outgrow it on their own pace. The only real threat is if it becomes a tool of authority, like teachers that depend upon it and mark down writing that the app doesn't like.
What it creates is induction currents in the surrounding water, with dissolved ions being pulled this way and that, against drag of the water, as the fields vary.

On DC lines, fields don't vary (much) so induce negligibly little currents.

In fresh water, there are fewer dissolved ions, but not none. Losses are less.

In perfectly pure water, small losses would come from swinging water molecules to point this way and that. Raindrops hanging on AC transmission line wires consume negligible power.
So if the underlying value changes enough that pasting anything but the values doesn't make sense then what's the UI here? Ctrl+C does nothing but Ctrl+Shift+C gives you the option to paste values with the inappropriate ones greyed out? Does the dotted border on the copied text go away because ctrl+C isn't going to work or does it stay because some portions of paste special can still work?
It’s not really directly related.

Miners load hash rate to get a better chance at the next block, the transactions just go along for the ride.

This would be true regardless of how much hash power is cumulative.

It's always important to remember that we live in a thin sheet of self-sustaining complexity in a cold, hostile universe, perhaps unique and if not incredibly rare. The "human" problems are a luxury when our fragile existence seems like little more than an accident.
Now we only need to get everyone to export to a standardized CSV, perhaps one adhering to its own name, comma separated values, and we are good.
What is that in money, 50 bucks? (Live in Germany, we have very high energy prices, so I relly don't know. Single in 50sqm Appartment, paying 47euros per month for a 100% renewable plan.)
I think it's coming as a reaction to Bill Gates's status as media darling; his own fondness for the limelight; and the fact that someone somewhere thought it was a good idea to make a documentary deifying his brain.
And you need to bootstrap your PoS system by enriching a bunch of insiders so that they can validate your transactions. PoS systems are unfit for being the decentralized digital store of value. Bitcoin has the most fair launch any cryptocurrency can ever have. There is no alternative for Bitcoin's use case.
Thanks so much for that read :-)
Um... Can you rephrase this such that people like me who aren't Bitcoin aficionados can understand it?

High-performance concurrency is just the kind of problem that may well require a complex solution.
It seems like there are a wide variety of ways to serialize and deserialize data, their performance sometimes varies by orders of magnitude, and the slow code persists because it doesn’t matter enough to optimize compared to other virtues like convenience and maintainability.

The key seems to be figuring out how to get good (not the best) performance when you mostly care about other things?

Machine learning itself seems like an example of throwing hardware at problems to try to improve the state of the art, to the point where it becomes so expensive that they have to think about performance more.
> So projects that aren't part of, or very tightly related to, search advertising are easy to fuck up without really any significant consequences to Google.

Not only that, but Google monetarily incentivizes frequent product (re)launches - it's the quickest way of getting a promotion and/or more bonuses, but maintaining an old product does nothing for your career or your team (unless you're Search). At some point, I assume the Google brand will lose enough goodwill that someone in leadership will finally address this.

Disclaimer: I'm not a Googler, but information on how Google measures performance and promotes staff is pretty much public information now.
"Those critics of Bitcoin who point to its energy usage (as of this writing, ~75 terawatt hours per year) seem unwilling to acknowledge the energy usage that keeps the US dollar afloat. The US economy used almost 29,000 terawatt hours in 2019. As confirmed by the US Treasury Department, the value of the dollar is backed by all the goods and services in the US economy which would also include its energy sector. Furthermore, in 2019 world energy consumption was something on the order of 120,000 terawatt hours. Bitcoin uses ~0.25% of US energy consumption and less than 0.05% of world energy consumption."

I had this happen with a strong antibiotic and a longer than usual course.

My gut has seen a lot from various parts of the world. It's like starting over.

The more places I revisit, the better things have become.

But yeah, significant changes. Ahem... lots of irregularity, as if many foods were new. (and in a sense they were)

The reintroduction idea is valid IMHO, based on some of my own experiences.
Original iOS and iPads were right - you should only be able to see a single piece of software and everything else should stop. This will make you safe and secure.
Surely proof of work also requires trust in a group of miners, trusting that 51% of them don't collude?

As mining complexity grows, surely this problem is only exasperated, since you need a bigger investment to be able to mine effectively, which would presumably result in an even smaller group of more powerful miners?
Perhaps you missed the fine print on the chart where it was comparing one BTC transaction to 100,000 visa transactions?

If the chart were anywhere close to 1:1 I could understand wanting to nitpick little details, but in this case go ahead and double/triple/quadruple the estimate, and it's still shocking.
I usually try and stay out of threads about publishing because I work in the industry and most of them are heated or incredibly vitriolic. (I'm employed in the industry as a software developer, not a journalist)

But this time I'm a little amused.

There's a lot of in-depth commentary by non-journalists about journalism. When non-software engineers comment about software development, or non-physicists comment about physical science there's usually much more ire for the lack of accuracy. And further, Substack (is that what's used instead of Medium now?) always seems to be posted with some kind of critique of every other journalistic outlet or platform. I guess that's how the new outlets get started now: react or rebel against something else? It worked for Canadaland and they've grown into their own so maybe it'll run a good course.

But I think the article isn't good. Why make such a sweeping statement when you're really only assessing an article or two in one or two publications?

Why treat all writing in a given publication as a common sum? They are editorialized and curated, but certainly not monolithic.

It's so dismissive and hand-wavy that I can hardly believe it's ranked this highly on HN and I must only assume it's because everyone everywhere seems to love to pile on a few things these days, and they always end up popular: how "bad" modern journalism is, how much artists should be paid (usually nothing), and any even remotely politically-charged subject. And each time, the story or the comments seem to be empty of compassion or even base-level empathy and understanding.

But I digress...

I think the title is misleading. This looks like a sneaky way to "phone home" using a `bgsound` tag to fetch a resource from FB's servers (instead of an `img` tag). No sound is actually played.
That save as... workflow is most annoying. Adobe does that too. In almost every scenario there’s a sync tool to take care of cloud storage. The web is great, but the web is slow and brittle. The cloud save is best when it’s an asynchronous background task.
Though I got downvoted quite a bit I thought it was an interesting question about the relationship between Objectivism and Game Theory and found a couple links. Keep in mind that these are from the Atlas institute so they are surely very biased opinions, but I thought it was interesting to see the defense of Objectivism in regards to game theory questions.

One about game theory and its relation to Objectivism: https://www.atlassociety.org/post/game-theory-and-objectivis...

And another about the Prisoners Dilemma specifically and which touches on the Nash equilibria: https://www.atlassociety.org/post/prisoners-dilemma

> political capital of bringing 'space jobs' to the middle of nowhere

Middle of nowhere is a non charitable as well as non accurate characterization of the area. South Texas and Brownsville are huge in the oil and gas industry. The number and quality of industrial, large structure welders available made the area very intriguing from that perspective alone I wager.

In fact the facility as it exists today is actually quite benign; you should visit if you haven't. It's literally right off the road down there. You can almost touch Starhopper through the fence.
Other already gave good answers. The main part is that
a house is not a consumption product - it is not "consumed" (used up) in a limited timespan, but rather, a bundle of a long-durable part (building) and an ultra-durable asset (land). Pretty much all durable assets have increased in price since the 1980s in tandem with falling interest rates[1]. The cause of the long term decline of interest rates is largely unknown.

The BLS largely circumvents this by using rents, actual rents for renters, and owner equivalent rents (OER) for owners. This is done by asking owners what they think their house would rent for, and using those increases for the housing/shelter component of CPI. Rents (which make up 1/3 of CPI) have increased faster than the general CPI, but not as much as house prices[1], likely because of the interest rate decrease.

There are some other complicating aspects around house prices (city prices increased faster than rural, houses sizes grew while household sizes shrank[3], so part of higher prices is just people buying more). But I believe the main aspects is really falling interests rates. A proper decomposition and attribution of most aspects probably takes months of work, enough for a econ Master theses. That's why I mentioned I don't have the energy for that. Nor do most other bloggers/pop-article writers, so they just go for popular appeal and clicks, by telling you why everything is getting worse and more expensive for you.

Does this actually include all the energy needed to maintain the VISA infrastructure too? Like the servers, energy used by VISA employees, offices, etc?
That's almost like asking "what is the correct number of sushi restaurants for a city?" The answer is a function of the marketplace.

In the case of cryptocurrencies, the answer is likely a combination of what miners and users can support. The goal is to be large enough that we don't have throughput problems and block space doesn't become a bidding war.

It's also worth mentioning that this doesn't mean the end-users have to be able to run nodes themselves or on mobile phones, since that makes use of a process called Simple Payment Verification (SPV) where they only process block headers and get the blocks they are interested in, but still verify the consensus of the network.

But, it also depends on what you see cryptocurrencies as. If you want them to replace traditional cash and create a "digital cash" world, then you want to see them accepted and used anywhere at a very large scale. In that world-view you have millions of transactions regularly and miners get paid with the sum of lots of small fees.

However, if you think that cryptocurrencies should only be used as a speculative asset or as a "digital gold" then you don't care much about it actually being transacted, and in that case fees as high as $50/tx are fine because you don't have any expectation that the world will be using it at scale.
Yes, the edit mode (using arrows to create formulas) is actually something I really find convenient.

To me it is a feature, not a bug. But yeah, F2 is fairly easy to use once you get used to it. Its like using VIM, the shortcuts seem annoying to the uninitiated, but once you get understand how everything works, the power can really speed things up and you appreciate it.
TLA+ is just a mathematical language; it doesn't do anything other than help you formally express the behaviour of discrete dynamical systems and write formal proofs of propositions about them. It was designed to be used with pen and paper, and often the greatest benefit comes from using it that way. Various automated tools -- two model checkers employing completely different algorithms and a proof assistant that also uses different technique to talk to different backends (SMT solvers, Isabelle, tableaux provers) -- were added much later, and at different times, and they each cover different subsets of the language. So the multitude of algorithms employed by the tools are not the primitives.

I've written a series of posts that covers the TLA+ theory (but it isn't a tutorial): https://pron.github.io/tlaplus

As a bit of background on Mito, it works by passing the parameters from the frontend spreadsheet to the Python kernel backend, which transpiles the spreadsheet formula into Python/Pandas code [0]. So what we're hoping to do down the line is let the user pick which language to translate to, SQL and R being the obvious next steps. But that's a ways away :)

Depends where in the US -- In Texas (as long as there aren't any blizzard-driven blackouts with accompanying rate spikes), retail electricity costs something like $0.10/kWh. In California, it's closer to $0.20/kWh.

So roughly somewhere between $70-$150.

I think the gold standard here is what Chromecast does with YouTube— tell the cast device directly what video to show instead of re-encoding and passing the whole thing over the network.

But of course, doing that requires application level support, or at least low-level hooks into the desktop rendering system to extract video streams and treat them differently from everything else. And if the video is being generated on the fly or is an uncompressed local preview, then you may be looking at an intermediate compression step regardless, but at least it could be compression suited for video instead of for text.
I do not know about 2021.

But few years ago this was definitely a problem and especially in border towns of Texas and Arizona.

But not just about brith certificates. You can look at legal immigrants. A lot of them are forced out of job because USCIS is taking their own sweet time of 24 months to approve their work permits. This means these legal immigrants have to quit their jobs, they can't drive as their driving license is expired and so on.

This is sheer caprice enabled by a hostile administration.

I am not against Americans having tighter immigration. Pass whatever tough laws you want and enforce them to hearts content. But when you have an admin that can be hostile to specific groups you have to be really suspicious of all government powers.
Does this also include all the energy required to maintain the VISA infrastructure too? Like the servers, employees, office etc!
Make a Ring Modulator with 2 lines of JavaScript
You have a gun barrel, some of the toughest steel around, which required to contain the supercritical mass long enough to allow for an efficient chain reaction. You stick a cone shaped object down the open end of the gun, and weld, or screw it into place with enough mechanical strength to stop an artillery round and keep it from exiting. More than 1/2 of the critical mass is likely here, with the air gap around it helping to keep the neutron flux low, for the time being. It is likely there is a neutron initiator on the very tip of the conical slug projecting into the barrel. (Think of shoving a ice cream cone into a pipe, narrow end first)

On the breech end, you insert a large "hollow point" slug of the rest of the critical mass. (an empty ice cream cone, open end first) The hole in the middle helps keep the neutron flux low, for now. Following this slug is the cordite explosive which will push the slug down the barrel at great speed.

The charge is set off, the slug rushes down the barrel, and gets wedged against the sides, in the process it breaks the neutron initiator, crushing it, and setting off a rush of neutrons, into the now complete, supercritical mass. The temperatures and pressures in the gun barrel begin to rise exponentially as the chain reaction takes off, within microseconds it is just the inertia of the barrel that helps keep things in place, the melting and even vaporization temperatures have been passed, but the contents have yet to disassemble completely, the chain reaction reaches its peak as the temperature climbs past 50,000,000 degrees, and then everything spreads outwards, 7/10ths of a gram of mass (the weight of about 3 rain drops) has been converted to energy, yielding the explosive yield equivalent of 15,000 tons of TNT.
Smaller is a benefit, but you're still beholden to Spotify or some other service holding your music for you, and continuing to honor the agreement.

Whether this agreement is stored as an NFT on the blockchain, or in Spotify's database doesn't matter, as long as they - or someone else! - can unilaterally yank that data out. And they can.

As far as files go, I'm reminded of the Robert Heinlein quote - probably mangled, maybe apocryphal - that you don't truly own anything you can't carry in your arms at a dead run.

Bitcoin has a lot going for it. But these arguments are so incredibly stupid.

Would the energy sector go away if the U.S. switched to Bitcoin? The American economy? No? Then it isn't a cost inherent to the U.S. dollar.

Not sure where you got that idea. RDP has been able to use the GPU for both encoding and the apps since Windows 7 era and both certainly still work on the current version of Windows 10. The main limitation I've run into is it's still limited to 30 FPS though.

Google's core product, search, has gotten so unreliable that I've already switched to using a mix of different engines.

Google now seems to fixate on the most generic terms in my query, ignoring quotations and other keywords, and emphasizes commercial results rather than informational ones. In addition, I can no longer tell someone to just google "something" and expect them to see the same result set.

What about other Google products? Well there's a good chance their next big thing will be discontinued within two or three years.

I've lost faith in them completely.
Bill Gates is either disingenuous or he doesn't understand Bitcoin. The electricity isn't expended to do transactions. That's part of the system. The electricity is expended to ensure there are no double spends. It would be arbitrarily easy to increase the number of transactions. That is not needed on the blockchain, at least right now.

The electricity is well spent securing a truly decentralized digital store of value. The world needs Bitcoin.
