The attack cost is based on extrapolated hashing power rental costs from NiceHash. NiceHash has 4% of the necessary hashing power needed to carry out an attack on Ethereum, so you would not be able to complete an attack for this cost.

From the 'Learn More' page:

> Note that the attack cost does not include the block rewards that the miner will receive for mining. In some cases this can be quite significant, and reduce the attack cost by up to 80%.

I made this website a few months back, and the goal wasn't to show the cost to attack Bitcoin, Ethereum, etc - it actually shows the exact opposite - it would be incredibly hard to pull off an attack without buying a ton of equipment since there isn't enough hashing power available for rent.

The point was to show the large risk that smaller coins have to being attacked.
The subtext is that Elon intentionally bumped the stock price to screw over short sellers like Jim Chanos. But the rationale behind 10b5 is to protect investors from fraud. Right, we are not concerned with protecting short-sellers who spend all day on twitter making up negative stories about their targets. So the underlying rationale here has to be that Elon's $420 tweet harmed regular investors who purchased TSLA at inflated prices during the time between his initial tweet and the announcement that there would be no go-private transaction.

The irony of SEC enforcement power is that the harsher they come down on the company or its execs, the more damage they do to the very investors they are charged with protecting. And I tihnk that is why you often see relatively modest settlements. Ya know, unless the board of Tesla is tired of Elon, I think there is a decent chance they are able to reach a settlement where Elon is not barred from serving as an officer or director.
I had a similar idea but I couldn't work out how to resolve all the issues that would cause.

So what is the technology here? The wikipedia article on zinc-air batteries says a rechargable one would have some great advantages, but also they have some major problems, like degrading over time and the number of recharge cycles.

That the company has been selling such batteries for a number of years and now is announcing it is going to go big time would seem to indicate it has figured out how to solve these problems, but how does it do it? I looked at the company's web site and it doesn't give any specifics. Though I did read somewhere that it has been granted over a hundred patents, so maybe they give some idea of what they are doing.
You're right, it is a mess.

Don't get me wrong, there's a huge number of packages available and a lot of them are really quality and I have used the language a lot, but good gosh is the packaging a deployment a fucking disaster.

Environments are a 3rd party bolt on, that relies on hacking around with environment variables. There's no distinction between dev dependencies and actual, application dependencies. The packaging/deployment tool has gone through a bunch of different formats/styles and when it comes to deploying your code, you have nothing better than writing a bash script that automates your environment creation, activation and running of the packaging tool (you then just hope that Pip doesn't fail on some bizarre edge).
Here's a guy, who admittedly was doing something really dumb, but managed to get his entire company's email accounts suspended:

Yes, and thanks for acknowledging that. But then the phrase "owe it to yourself" didn't really communicate your intent correctly, which is why I objected to it.
The company says the batteries can be used in autos, which would seem to indicate they hve solved that problem. But who knows until we get some independent testing.
Yeah, it would have flown, and did. Remember when the MacBook first came out and every 5th it 6th white one had a dark yellow film? Or how the touch pads had waves and wobbles in them? The MacBook Pro exploding and misshapen batteries? The MacBook Pro thermal paste issues and how they ran at up to 100C and shut themselves down? Every time some big new production change happens there are teething problems no matter who’s in charge.

> $802,538.64 for the 3-year term. I wonder how that compares to building your own on-premise host with that much RAM

This was discussed a couple days ago in a different thread [1], when 4TB was the EC2 limit.

$400k for the current-gen (224 cores) or, as a sibling comment [2] notes, $250k for the previous CPU generation (which can use twice as many DIMMs of half the density and only 192 cores of that).

> obviously, there's operational costs to consider as well

We can estimate an upper bound on this, given that the current-gen system has N+2 5x1600W 96% efficient PSUs, so 5kW max. If you're paying a colo $.50/kWh, that's another $66k over 3 years worst case.

Realistically, though, CPUs with a max TDP of 1640W, DIMMs (generously) 700W, leaves plenty of room for fans, SSDs and other overhead before getting to 3kW or $40k, and that's still assuming running full-bore the whole time.

There are obviously also ancillary costs to AWS, such as data transfer and EBS.

If you're already running your own hardware, it sure does look more attractive to pay $400k now and $40k over 3 years than to pay AWS $800k All Up Front (now). If not, perhaps it's more attractive to hand-wave away that $360k as saving the "hassle" of hiring someone who knows how to run equipment in a datacenter.

Bitcoin cash isn't censored. It has its own subreddit (and the rest of the internet) where discussion can be had about it.

Equating "censored in r/bitcoin" with censorship in general sort of proves that it's mostly about politics; you want to be uncensored _in a specific private community_. If BCH can stand on its own merit (and hopefully it can!) then you don't need that. Those who think it does need that aren't trying to make BCH successful, they want to control Bitcoin. And so it makes sense that people with those motives should not be allowed.

The language doesn't surprise me particularly.

"Pray" is an old word that means to ask. Hence "prithee", which is kind of a mashed together "pray thee" (which means "ask you"). And "prayer" is noun form of that verb.

Yes, the words are really old (archaic-sounding if not actually archaic), but that happens all the time in legalese.

And yes, they have religious connotations, but they are also used in secular ways. For example, from Shakespeare's "Romeo and Juliet": "I pray thee, good Mercutio, let's retire: The day is hot, the Capulets abroad".

The key would be a permission prompt like browsers now have for camera access, notifications, geolocation, pop ups, etc.

If a page uses too much CPU it will get throttled and ask the user if they want to unthrottle it.

Website owners currently assume they’re entitled to as much of my processor time and battery life as they want, just as they once assumed they were entitled to display popup ads just because they could. If this behavior is going to change, it will only happen because browsers stop letting them and instead say “No, this is the user’s CPU time, not yours.”

coupling with the Great Recession, that at least gave bitcoin massive fuel

Whatever fuel that contributed, it probably pales in comparison to the fuel contributed by Mark Karpeles' market manipulation at MtGox.

That's what really caught people's attention, and after that was when large scale VC money started to flow in, because the market manipulation and subsequent price spikes gave the impression that this was a growth market worthy of deploying capital into.

After the collapse of MtGox, and what was going on behind the scenes became apparent, you had lots of people with money invested under the false pretence of great interest and demand for this new thing.

So they had to decide were they going to take the loss, or pickup the torch from MtGox, and thus we got blockchain fever.

Whatever utility there is in blockchain crypto-currencies, the game to this point has been "Hey I'm gonna buy some of this stuff, then convince other people to do the same, because it is magic internet money!

True. But how much sense does it make to believe a 18-year-old one is going to be so much more reasonable than a 17.5-year-old one that it would make such a fundamental difference worth such a difference in legal rights? Time doesn't even exist objectively, needless to say, the idea of using it as a precise measure of a character maturity is a disaster.

That's why I put "perfectly" in quotes. The only way to make a perfectly timed signal is to be precise down to one plank. That's obviously a ridiculous definition because we can't even make any hardware that can differentiate such precise inputs. Perfectly timed in EE means to within operating specs so that the chip does what you want. It's the only definition that makes sense.

What you're describing, by the way, is a feature at the MAC level, not the PHY level (think signals vs data frames vs packets). The vast majority of ICs are all push based so they just continue normal operation when there is power but no other inputs. Your example still requires timing your clock/enable signal so that the ringing on data lines settles down before clk/en rises and the data doesn't change before the rising edge is detected.

But that's not what happened, so I tend to believe that OYO recommendtions are in fact reliable, except in rare cases.

Only people who have enough money to invest can do so. For the low-earner, it becomes near impossible to save up for investment because the savings either need to be devalued or put into risky investments.

Saving is a perfectly viable choice. If someone wants to save, it is not for you or your cronies to tell them they can't, or that you must shave your cut off their savings each year.

It's a myth that people won't spend. People will save the good money and spend bad money. The bad money is still getting spent, but of course, it's constantly losing its value.

The difference is the perspective on how money should be spent. Savers are low time preference people. They would rather spend their money on the future, on things that last. High time preference proponents on the other hand, only care about the next quarter, will cut corners to maximize their short term profit, and will spend their profit on cars and other depreciating assets to avoid paying the tax on their profits. They also build products which are intended to fail, so that the consumer has to buy the upgrade in a few years.
