Thank God, no. And, of course, there are plenty of safe options for storing Bitcoin. I don't own any Bitcoin (what little cryptocurrency I do own is all ETH), and while I did look at some of the HSMs out there for myself, at the time I looked, there weren't any that were designed around ETH (that I could find, anyway) and I felt pretty confident about my own ability to secure things with existing, open, technologies.

That said, even though there are plenty of options for securing BTC, there are exactly 0 options that my family would use over the convenience of Coinbase/a "service that looks like a bank" because they fully trust the entity involved. And if they didn't, they'd fully (incorrectly) trust their ability to keep their wallet safe on their own home computer that is protected by exactly nothing. Convincing them that they need to spend additional money to gain that security and accept with it the inconveniences that it introduces would be impossible. Never underestimate the power of "It won't happen to me".
I would imagine that the difficulty in charging is proportional to the cell's capacity, so charging 2*n cell shouldn't be any harder than charging n cells, as long as the cell's capacity is the same. If you increase the capacity of a cell, then you might have to innovate.
You may be right. But there's nothing wrong with it. Tesla has done amazing things, and so has SpaceX. Yes, they're in the habit of being late. But neither has, as far as I can remember, ever produced "vapourware" they didn't eventually start selling.

For a nice reference: see this comment sceptical of Tesla's capability to deliver this 100MW battery in Australia in 100 days. Which was just recently completed on time. The tone reads surprisingly similar to the Bloomberg article ("To say nothing of the near 50 degree weather beating down on old infrastructre that spans thousands of very sparse kilometers.") https://news.ycombinator.com/item?id=13838355

People, and companies, have reputations. Those have to be taken into account when judging their claims.

Note also that all of the claims of the article are in the "this is hard" territory, not any actual "this is perpetual motion" sort of impossibility as the title alludes to.

The example that seems easiest to judge is doubling the capacity of the roadster battery: The current Model S battery is a rather thin sheet underneath the car. I have absolutely no doubt that you can fit twice the volume into the same frame. It gets only easier if there are any advances in battery density, or if car grows only slightly in every dimension.
I think most people are in agreement that the lithium ion battery is less-than-ideal technology that's due for replacement. And we have a number of innovations in battery technology vying for the opportunity.

It's starting to feel a bit like Tesla's massive investments are only serving to further entrench the existing battery model. He's basically working to replace Big Oil with Big Lithium. There's no denying the benefits of breaking our addiction to fossil fuels, but we need to be mindful of the obstacles to tomorrow's progress we're erecting in the name of today's.

Simon of the Desert is a famous 1965 foreign film by a famous director (Luis Bunuel) that is loosely based on the life of one of these Stylite ascetics.

The article is talking about wastewater injection. Injecting mud while drilling isn't causing stress on faults, but rather wastewaster injection.

I recently switched jobs and went through several rounds of interviews with several companies and the MOOCs I listed on my resume always came up. They served as a way for the interviewer to segue into the topic rather than a blind trust like a degree served. Not only did they show self motivation but they also acted as a way to shift the interview towards a subject I'm familiar with.

I think some of that shift is probably because of interviewers second guessing those courses though.

They are closer to Yellowstone and further from New Madrid. Curious if you have ever been to the Yellowstone Caldera.
They would if they were pulling straight from the grid. Go to your power company and ask how much it would cost to surge a mega watt of power at peak times. Those kinds of surges are really expensive to handle. Of course Tesla uses storage and solar to smooth their demand so that they can pay normal rates.
That must be the case, but we don't know what numbers they used to come to this cost. The number was just thrown out there without anything backing it up and is an order of magnitude off from what would be expected.
All these EVs use roughly the same small cells, right? Essentially thousands of the same cells used in hobbyist RC aircraft (with which I’m fairly familiar)?

Unless I’m mistaken, each little cell should theoretically be chargeable in parallel, limited only by heat, massively parallel wiring, and the one massive input carrying ridiculous current.

In theory, if one cell takes 30 minutes to charge, all cells could be charged in parallel in 30 minutes. Obviously this is ignoring the challenges I mentioned, which generally don’t apply to the relatively small RC aircraft with which I have experience.
What a weird thing to say. People don't buy ebikes for an entry jnto electric, they buy them because they're a really convenient, fast and fun way to commute.
That is how they work today. This is Tesla's current state of the art (larger) battery. As you might image in takes more than 1-2 to run a car.

If you wanted to bail out the home speculators individually, the analogous approach would be to buy their houses at below the prices the speculators had paid, essentially a short sale.

Is it possible that the concept of "money" has been upgraded? That cryptocurrencies are simply better as a store of value than dollars, for reasons A through Z? For example, people don't like the costs and regulations associated with fiat currencies - therefore, crypto is better for them. It's like trying to ban alcohol or drugs - people still like them, so you can never ban them, no matter what the government wants. So crypto will never be banned (longterm).

It's still such early days in this area, if you are curious at all, buy some BTC and ETH and sit on it.

I haven't had this issue with Amazon myself, but the threat of it does weigh on my mind. Nonetheless, what pushed me over the edge of not buying from them anymore is they really just don't care what happens once a package leaves the warehouse.

Amazon insists on regularly using a specific carrier to get product to me which alters altogether the concept of what it means to get product to someone. There's a whole story behind this, but Amazon is a big company and clearly is shooting to satisfy the lowest common denominator. I've tried to resolve my issues with them but just get whatever script their corporate spokeshole gives to customer support to parrot. I get it, I'm not their common problem... but since I'm their edge case... I'm done with them.

I will shop Amazon chiefly as a sort of search engine when necessary and buy direct or from some other seller once I know the product exists; maybe use them for price check. In fact, given the unreliability of Amazon actually getting product to me in any predictable fashion, it's usually just more convenient to drive to a B&M store and make the purchase (I do check inventory before I leave the house ;-) ).

I recently had to set up a 3 computer SSH tunnel and wrote about it, maybe people will find it interesting:

https://vadosware.io/post/ssh-tunneling-using-an-intermediar...

I first tried to setup OpenVPN and only wanted to use the the SSH tunnel for DNS purposes (I couldn't use normal DDNS tools), but in the end, I ended up running a SOCKS proxy over the tunnel and it was stunningly effective, enough that watching Netflix despite intercontinental round trips.
Even having the possibility of all the crap that goes along with copy-pasting and broken formatting is a negative for me, not to mention the wasted hotkeys.
The stuff magic to me is the tools that speak both HTTPS + SSH or some other protocol, showing some normal site to anyone but those in the know.

I've never had to use them since as you say few are that hardcore in their lockdowns, but it's nice to know they exist.
Good luck with that. I mean no disrespect, but I'm guessing you don't have much experience in this sort of thing if you're asking how to short bitcoin and claiming you've predicted the top of the market when it's been steadily climbing for 7+ years. It doesn't matter what reasoning you've come up with, markets are rarely driven by reason. As a wise man once said, the market can stay irrational longer than you can stay solvent.

If you want to make money, buy BTC. You might win and you might lose, but your odds are far better than if you try to short something that has made a 1000% gain in the last 12 months.
It's typical anti-Tesla propaganda.

"Wow a little googling on this subject led me to sshuttle, which I've never heard of before but looks awesome"

sshuttle is indeed awesome - a viable VPN that requires nothing on the endpoint but a functioning ssh login (and python on the remote host).

So any host, anywhere, with no configuration (and no permission required by the operators) that you can ssh into ... is now a VPN endpoint for you.

Sibling comments in this thread are pointing out that ssh has this functionality already and that is true, but some configuration and maintenance (and understanding) is required. Not so with sshuttle.

ALSO:

We (rsync.net) sponsored the reworking of the ipfw target for sshuttle so that it now works properly on FreeBSD with the --dns option, etc. We also sponsored proper UDP tunneling for sshuttle on FreeBSD but I am not sure those patches are in a -release version of FreeBSD yet ...

You need to use FreeBSD 11.0 (not 11.1) and you need to:

git clone https://github.com/sshuttle/sshuttle.git
cd sshuttle ; git checkout c746d6f7db3efbad6caddea76bdf916c46cf5c6e

... and that will get you a working sshuttle on FreeBSD with --dns support.

I recently sold a bunch of Bitcoin, and I believe it will go down, but I would never, ever short it.

When you are long you have limited downside because the price can never go below zero. When you are short your downside is unlimited because there is no limit to how high the price can go.

Bitcoin could easily quadruple in a few months before any crash happens, and your short would probably just be liquidated at a total loss to you even if a crash comes later. As we all know, markets can remain irrational longer than you can remain solvent, and these markets are very irrational right now, as clearly demonstrated by the nonsensical valuation of recent scam Bitcoin forks "Bitcoin Gold" and "Bitcoin Diamond".

reddit found that some Adidas Ultra Boost sneakers sold on Amazon were replicas (fake). The authentic and replica sneakers are co-mingled. It's crap shoot what you get; even some "ships from and sold by Amazon.com" sneakers were fakes.

Amazon's response is to issue a refund if you receive reps. However replicas are often quite convincing, and most customers won't know how to tell the difference. The carelessness here is just astounding: it seems like they're begging for a lawsuit.

The USB-C PD charger bricks just have a single USB-C slot. You can use the provided cable or get your own longer/shorter/braided version. There are also third party USB adapters that mimic magsafe functionality, albeit not as amazing as proper "Apple designed" magsafe of the past.

Given the new USB-C everything paradigm and the available options I don't think ditching these plastic clips is that huge of a fumble for them-- Although I would like to see proper L shaped USB plug options on BOTH ends of the cable from Apple, Nintendo (Switch seriously needs aux charging port in back or on top) and any other third party that wants my money.
Yeah, I do think your view is a bit skewed. There's an ever-growing number of users that grew up with computers, who know at least how to install a different program on their own, despite most definitely not being a techie either.

And even among techies, I think you overestimate how many actually care about much else than "fast" when it comes to a browser. Just look at how many techies run Chrome. It's usually not the most wizardly of techies, but a good number of techies either way.

Comparing on a percentage point basis, you have to ensure that the underlying physical system is equivalent, in this case, the capacity of the batteries.

Current superchargers charge at 2% / minute. I am assuming that's the maximum rate of charge, given the current supercharger infrastructure.

Lets assume that 2% / min is, say, at a 100 kW power level.

When charging a truck, assuming the supercharger technology isn't changed, the charging will still be at 100 kW power level.

So if the truck has 10 times the battery capacity, then the equivalent %age rate of charge will be 0.2%, not the same 2% as the capacity of the battery to be charged has changed.

Personally I think Elon is either going to add multiple charging inputs per truck and combine it with a special supercharger, or have some sort of port in the truck to which a special connector is connected to transfer huge amounts of power safely, not unlike a dock at the under side of the truck, or maybe the front.
> And we have a number of innovations in battery technology vying for the opportunity.

No, we don't. We have lots of news articles about amazing breakthroughs and absolutely nothing in actual production.

> It's starting to feel a bit like Tesla's massive investments are only serving to further entrench the existing battery model.

If you can come up with a battery chemistry that outperforms lithium ion, there will be nothing stopping the absolutely massive torrential downpour of money on top of you. Batteries are used everywhere, not just in cars. A new chemistry that works well would be huge. The problem is that there's lots of hype and marginal results when it comes to new battery tech.
Wait, are you concluding that having batteries with more cells is not the same as increasing the capacity of the system?

For any battery system, the capacity is the product of the number of cells and capacity per cell.

The current relation model between nations made nobody fully trust each others. So nobody wants to drop their military, unless everybody do it at same time (Which is impossible).

But it's the world we live in now, there is no other choose but get use to it.

One day in the future, we may reach a higher level of globe society that could maintain itself without any military force. And, that's why everybody should keep pushing the society go forward.

But until we reached that point, everybody will continue upgrading their military, and rely on it to ensure their own safety.

I'm no battery expert, but is it possible that they have several battery compartments that can all be charged simultaneously? Thus reducing charge time?

My point is that having a larger capacity battery automatically increases the wattage at which you can recharge. It's not like a gas tank where a 100L tank takes longer to refill than a 50L tank.
If all of them are connected in parallel, then you are right. It's like filling an array of glasses in the rain.

However the superchargers connect to the vehicle through a power port, which is relatively small. So it may not have as many parallel connections. You could split the charging to individual cells inside the car, allowing for parallel charging of all the cells simultaneously, but that means that the supercharger has to handle the cumulative power requirement of all the cells in parallel. So if you have 500 50W cells, then the super charger has to have the capacity to handle 25 kW of power. And that much power requires some very bulky cabling, even with a 3-phase supply.
