Two reasons you should not short Bitcoin.

1) Actual legitimate Bitcoin payments are increasing and real.

https://blog.bitpay.com/bitpay-growth-2017/

2) Even if this whole thing does collapse, never short something like Bitcoin unless you have unlimited cash to support such a short. Even if you're right, can you continue to sustain your short if the peak is $100,000 a coin before the collapse? (And the new bottom is $10,000, still higher than right now)

If the price goes there, can you afford the short?
It's a systemic problem with Amazon's marketplace, but their stock has been performing well, so until they start taking multi-quarter financial hits, their executives don't have a huge incentive to care about these marketplace problems.

The FBA aspect of Amazon has created many of the problems, such as fake reviews, merchant scamming, and counterfeit products, but FBA sellers are also a huge money maker for Amazon, so they are in a very precarious situation of managing expectations across their customers, sellers, and themselves.
Interactive brokers accounts can trade cme futures. Whenever these come out it will be just what you're looking for. The margin requirements allow you to short with a lot of leverage too.

Good luck.
Given the complaints about the Touch bar, and also about some of the specs, maybe they're better off ditching it and throwing in some more ram? Who knows
Though, there is no shortage of attacks against electronic wallets on personal computing devices either. The average, technologically moronic user might actually be safer storing his Bitcoin on a trustworthy exchange, as opposed to a personal wallet protected by a weak passphrase, if any, on the same computer/phone where he surfs, reads email and runs software of dubious origin.

Best way to protect against unauthorized use of your funds, as the article notes, is to go really old school and print your private keys out on a piece of paper, and store it in a physical vault.

Of course, none of this would be a problem if the exchange acted as a trusted ledger and could simply revert any unauthorized transactions on the user's funds. Like a traditional bank, but just with all the crypto hype!
No, the idea is that your language should be able to express patterns in the language. Then they're not patterns any more—they're libraries! Working with an explicit abstraction from a library is far more pleasant than working with an implicit abstraction from a book.

The way to achieve this is emphatically not adding patterns to the language spec. Instead, you want small and simple languages that can grow—languages flexible enough to add new abstractions that let you write code the way you want.

"Growing a Language"[1] by Guy Steele expounds on this and, as a bonus, is the single best technical talk I've ever watched. Highly recommend watching it[1] or, if you're pressed for time, reading the transcript[2].

I meant integrating it into FFI's expecting C code. It's true that it makes stronger guarantees. I have a concept also that's called Brute Force Assurance where one source gets converted into Rust, Frama-C, and SPARK. Idea is static analysis tools for each knock out errors others can't catch. Final result is portable C.
Potbelly's is the best chain I've run into, and here in New England pretty much every pizza place and convenience store will make you a drool-worthy Italian (or grinder or hero, depending on who owns the place).
The mostly efficient market. You can get far picking stocks at random, but that doesn't mean it's better than having some idea about what you're doing. But for the most part it's about risk, not price. Price is usually about right, it's what you can afford to risk. I think Amazon's price went up because investors think they're about to battle Walmart. Wouldn't hurt to put a little in on both those companies.
Although it is very good to be skeptical, it makes the article less valuable than it could have been. 'Musk claimed X and people we talked to said they don't know how it's possible.' I am not saying that the people they consulted didn't know how, but using just that for the entire article was unnecessary. They also claim battery density is increasing by Y% and maybe Tesla is banking on that. Well those density increases because someone somewhere is finding ways to do it. It's not happening by some magic. Maybe Tesla found some ways to improve it? Why do they have to rely on someone else?

Maybe I am being too critical of the article and I understand that author too can do very little but speculate. But maybe consult variety of people rather than just 'I don't know how so it must not be possible' people.

Edit: is there a way for tesla to purchase electricity for solar city customers or something and direct it to charging stations? Or is that now how it all works?
Eric Schmidt talks about AI at MIT conference
Before futures work, you need forwards. There are no bitcoin forwards because the entirety of the current bitcoin ecosystem is built on and around fraud. If we are to remove fraud and clearly currently defined as illegal activities from this ecosystem bitcoin and its value will collapse through the floor.

In order for forward market to be viable you need to have a stick big enough where pulling out of a forward contract is impossible for anyone without them going to jail and ( not or ) still having to perform under this contract.

The really funny part is that the feeding on the suckers ( i.e. retail pansies ) is so profitable and regulators are so pathetic that those who based on their other dealings should not touch BTC with a hundred yard pole (i.e. VCs, exchanges, law firms ) are jumping into it not just with both feet but on all fours.

I went to a BTC investors/tech people meet up not long ago. Some of the people were household names in this "community". No one could describe a difference between POS and POW; no one could speculate on internally consistent basis what kind of outcomes would be possible based on the actions of China's central bank. But everyone was very excited about all the conferences they were going to and all the money they were making off the suckers.

It really reminded me of months before the dotcom crash.
The point is that patterns shouldn't be patterns in books—they should be abstractions in libraries. You know what's better than having a shared vocabulary you expect everyone to know from a book? Having a shared vocabulary defined in the language and accessible not only to programmers but to the compiler and tooling as well.
I'm here to third this assessment. The feel of the butterfly switch is so much better for long bouts of coding/typing and, in my particular case, improved accuracy.

I think the issue is that the scissors switch encourages typing using the tips of the fingers (deeper key travel) whereas the butterfly keys encourage using the pads of the fingers which reduces exertion and fatigue.

My understanding is that the failure rate for the butterfly keys is "significant [...] but 'less than 5% for sure.'" [0] Marco Ament (thread OP) and John Gruber (Daring Fireball) are proponents of keyboards that take more effort to use, Gruber's favorite keyboard being the Apple Extended Keyboard II. [1][2]

Some aficionados' opinions about keyboards reach heights usually reserved for out-of-production American muscle-car transmissions. [3] Reading the tenor of some descriptions of the action of these old-timey keyboards, e.g.

> tank but with a more metallic, punchy feel, and an audible note to its
> astoundingly loud typing sound, [3]

one can practically feel the adoration of these self-identified keyboard nerds for a particular type of vintage keyboard.

I personally prefer subtlety and finesse when I interaction with peripheral devices, so I welcome the move toward shallower key travel.

YMMV

It's not possible. At that scale the Earth is not rigid enough to transfer the strain that far, and the forces involved are too small.

The activity of the Yellowstone Caldera results from large scale processes in the Crust and Mantle. Direct injection into the caldera MIGHT be enough to trigger an eruption that was already imminent.

Re: 2

Everything you say is true and acknowledged in the article, but as ML also points out they are also all arguments against bitcoin.
Upvoted, because there's nothing wrong with this sort of comment, and this and the posts above represent two sides of the same coin--one wants to support, the other wants to tear down, but is shielded behind a veneer of "helpfulness" or "constructive criticism," when in fact it is not.

Complainers complain, and like attracts like. If people want to assert that supportive comments don't "contribute," then knee-jerk downvotes for their own sake are equally unhelpful.
No. Payloads are tiny. Travel time is very slow.
“Every time the global supply of batteries doubled, prices drop 19%”

“Every year the energy density of batteries increases by about 7.5%”

So, in 10 years electric cars will double their range, which should be more than enough for most people.

> Only fools keep substantial Bitcoin balances in exchange wallets.

Or, "regular folks". My in-laws who have no idea what it actually is that they purchased use Coinbase and have no idea that doing so is not much better than giving your wallet to a stranger and asking them to keep the money safe and have it available when you want to go to McDonald's.

Is it all that much better than them keeping it in a local wallet for them? I wouldn't trust my in-laws to keep their computer safe from the myriad of threats that the Internet has to offer. I wouldn't trust my parents to use a password more complicated than one originating from the Spaceballs movie to protect their private key (let alone them understand with any level of accuracy what a "private key" actually is). I'd put more faith in Coinbase handling that for them, despite being a radically larger target than they are as individuals.

For us? Yeah, it's an insane proposition. My ETH lived in my Coinbase wallet from about the time that I noticed the transaction went from Pending to Completed to about the time it took me to fill out the form to turn it into cash to deposit into my savings account at my local bank. And the first time I used Coinbase, I moved the first couple of coins one at a time just to limit my losses if something went horribly wrong.

The thing is, to secure it well, locally, you have to do quite a lot. My wallet keys and wallet aren't even stored on a computer -- I've got them on three encrypted thumb drives, one in a safe at my house, one in a safe at my parent's house and one handy. I fire up a VM started from a checkpoint just after installation (after running updates) which itself is stored on an encrypted volume when I need to move money from my wallet to reduce the risk that my machine was compromised with something looking for those keys -- ready to swipe them on access[0]. My parents inherently trust the software and their computer to not become their enemy and wouldn't take even the most basic precautions around protecting their key from loss (Hi, son, I was wondering how to reset my password on my wallet; I forgot it) let alone protect their key from folks who write malware designed to steal it.

[0] All the while not being sure something exists out there for ETH, but knowing that if the price continues to go where it's going, it absolutely will.
No, not really. It makes it useful for criminals, and a small number of people who might have good reasons to buy things, but that doesn't mean it should have a market cap of billions.

I'm not saying there are no good uses for bitcoin, of course. For example, if someone used bitcoin to import prescription drugs from Canada to the U.S, that's great. But it doesn't justify a $100B+ market cap, and as it stands, the hard part of doing that is importing the drugs, not exporting the money.

Similarly, just because Tor is useful mostly to criminals and a few human-rights advocates or privacy enthusiasts, I don't expect the Tor Browser to ever gain a major market share.

Honestly? I always go back to the core MS fonts (Arial, Courier New, Times New Roman, etc...). I even use the Fixedsys typeface when coding. They're usable, familiar, and most importantly, look good at small sizes.

The downside is that an unusual renderings (e.g. Font size 17), they don't look great, but it's a small price to pay.
"Tesla offers free electricity to most of its Model S and Model X customers while paying almost $1 per kilowatt hour to produce it, Morsy said. That amounts to a subsidy of as much as $1,000 per car in 2017."

I realize that most people believe that Tesla and Uber will be able to continue subsidising their operations indefinitely, but it makes me very nervous.

> the natural conclusion according to the article's tone and content would probably be some asinine assertion like China > USA, Americans/British/people from Western society are silly/irrational/incompetent, communism > democracy, etc.

i agree that the article was underdeveloped, but im not sure your critique is entirely fair. the author did go on for a while about that girl, nian, and how inhospitable china was to someone very similar to him. he also hints at how warped the party's version of chinese history is. i think its far from clear that the author thinks china is superior to the west, or vice versa.

True; bread is pretty important. In SF sourdough is pretty prevalent --and that's ok, but it's not my preference. It's too tough --at times a bit like leather, so I prefer other types of crunchy loaves. Dutch crunch or baguette-style or even kummelweck.
I see the world as a giant lake full of ships going into different directions and sometimes turning around randomly.

As an individual, you can try to get to steer a ship or you can try to jump to ships you cross with that go in other directions.

Both strategies have a random aspect but if you know where you want to go, and act accordingly on the opportunities presented to you, you can progress toward your goal in an uncertain goal.

The main takeaways are that the world does not owe anything to anyone, even to smart kids, and that merit is hard to discern from luck.
I just checked it out on github - that is indeed a nice font for development.
> Poor contrast and unreadable font is still visible even on your screenshot,

That’s an artifact of the camera, not the page. On a properly calibrated screen supporting the Rec.2020 colorspace with at least 1000 nits of color, this will have more than enough contrast.

The big problem is that today, between #454545 and the background a user with a 1000 nits screen and one with a 100 nits screen will see a difference in contrast of almost an order of magnitude.

TL;DR: Either you need to calibrate your screen, need a better one, or we need a way to specify the absolute brightness that a page should be shown with in code.
Oh, sorry. I believe one of the main exchanges (bitsane/bitfinex Maybe?) was going to make options and margin accounts available, don’t remember which one. There’s also cex.io, but it’s in the UK.

I guess you’ll have to wait for JP Morgan’s fund to go live...
If this were any other company making such unsubstantiated claims that didn't have any basis in the reality of the underlying technology, they'd be getting roasted here.
White Castle also isn't present across most of America either. Subway is the largest fast food chain in the world so it would be more interesting to hear what sort of presence they have.

Are you using any UI kit, like Bootstrap or Bulma? That makes creating decent looking web applications so much easier.

I agree, I should have mentioned free cash flow. Of course the real answer is to look at many metrics and get a broad picture. But I doubt you are going to find a "value investing" reason to buy AMZN at these levels, it's clearly a growth stock.
This is going to speak to my naivety around futures and how they work but if you're ending up with cash instead of bitcoin and there's no actual bitcoin wallets/bitcoins involved, what on earth are you actually buying when you buy a Bitcoin future in this manner? It sounds like the one, sure, answer is "not Bitcoin". Can anyone explain this to a neophyte like me?
The Greatest Computer Network You’ve Never Heard of (PLATO System)
We should be careful with apply Moore's Law style of thinking when it comes to battery innovation. These things can and will hit hard limits at some point. Real progress can be much slower and much less predictable than in the semiconductor industry.
Very good supplement information. I didn't realize Li ion batteries were so close to their theoretical limit.
Traders will devise a suitable risk management plan prior to initiating a short position. Unlike the media driven nonsense about a large activist shorting a bull market permanently, many traders can and do make leveraged long and short trades all the time, with the intention of exiting at a loss if the trade doesn’t go immediately (for some definition of immediately) in their favor.

Bingo. Not only that, but they may even rely on battery extrapolations for 2022, despite the truck and car being launched in 2019-2020. All they need is to break-even in the first year or two, and then they can make-up the profits from the improvement in battery prices. That said, the roadster itself will likely be profitable from day one. It's the truck that may not be.

This is why Musk keeps getting ahead of everyone else and leaves carmakers and media writers in "shock and awe" - because he keeps thinking outside of the box, while they keep thinking within the existing or past constraints.
So much this. I didn't grow up on a farm but I put up with the downsides of a white collar city job so that my kids will never have to pick up a skill because they couldn't afford to pay for the services of someone who had the skill.

Blue collar lines of work are nice and from time to time I do miss the construction, food service and mechanics jobs I had before my current career. There's a lot of job satisfaction to be had from seeing the physical results of your labor but satisfaction doesn't put gas in the tank.
I don't agree that people having some investment in Bitcoin without ever holding Bitcoin is a disadvantage.

Once of the things we used to talk about years ago with Bitcoin was that by the time Grandma owns Bitcoin in some way, it would be via several layers on top.

And we were not talking about technology layers like LN, we were discussing that eventually financial products would be built on top of Bitcoin.

I see this as the market maturing and even die hard Bitcoin fans should see this as a good thing.

It's unrealistic to expect everyone that interfaces/holds value in Bitcoin to actually use the raw layer itself.
The funny thing is that it really hasn't been that much less predictable. Progress has been slow but steady and Tesla's business model has been built around largely predictable technological progress.

7.5%/year is probably an overestimate, though, and you are right that at some point it will hit diminishing returns. Moore's law has too, though, eh?
Animals need taking care of every day year-round. There's very few homesteaders who don't have at least some egg-laying chickens. I have a feeling you're thinking more about industrial-scale monoculture farmers, but that's not what the linked article is talking about.
Few people argued back and forth that it could be a used alien rocket booster.
With a 50% width space option, the duospace approach might be usable for “pedantic” code indentation (that is indentation beyond just nesting, but also vertically aligning elements other than the start)
Don't bother. It's just a decoy.

What we really need to do is start combing the databases for anomalous X-ray flares so we can find any nearby Oasa emitters.
I’ve had this happen too. But I wouldn’t want to go back to the previous gen keyboard.
If he was completely alone on the Island, who took those beautifully composed pictures of him fishing, considering it was the 50s where there were no electronic cameras with timers and stuff? ex: http://www.janesoceania.com/suvarov_tom_neale/fishing.jpg

Was it Tagi, the pearl diver? If yes, then he wasn't really alone, was he? What am I missing from this situation?
I don't really agree. If another company rolled a 200kwh car out of the back of a truck, did a few passes of the stage, gave passengers rides (high speed launches) for a while, and then reported ~60% battery remaining, I think most would believe them.

We would also wonder about making it to production, but Tesla actually has a halfway decent track record at that.
If you have 10k users and you still need a day job, you don't have a business.
Oh yes, definitely there are plenty of other tradeoffs involved with CLJS vs JS that are much more nuanced, and as you said, immutable by default is by no means a silver bullet. There's a reason why I still by choice use JS for certain projects when CLJS exists.

I was only lamenting what I consider to be the only major deficiency in JS when it comes to writing functional code, one that I haven't really found any viable way to work around, despite being quite happy with most other aspects of the overall experience of writing functional JS.
Flexibility doesn't necessarily mean portability. Always having to remember to take the right dongle is wasted mental effort. I'd rather lug around a slightly heavier device.

I'm writing to you on a 6.5lb laptop with FireWire, VGA, HDMI, DisplayPort, two 3.5mm audio jacks, SD 5 USB-A and 3 USB-C. And in all honesty, I sort of miss having a 9 pin serial port.
> Once you accept that, the discussion boils down to your belief in what constitutes a fair taxation scheme: should the users of a service pay per use, or should essential city services be subsidized by the wealthiest citizens? Good arguments for and against.

Very tangentially related but wanted to hear your opinion on this: I know it is not in my best interest as a poor person but I think there should not be any handouts or subsidies for poor people. We should transform any entitlement program that requires you to show you make $X or under a year and replace them with programs that everyone (regardless of income or wealth) can participate in. I am still a firm believer in a progressive tax regime to fund these programs but we should not divide beneficiaries based on income or wealth.

Another thought experiment I sometimes think about is what would change if public transit were fully paid for by taxes? How would things change? Would we see more traffic? How much more traffic would we see? Would we see more people camping out inside the subway stations?
“entirety of the current bitcoin ecosystem is built on and around fraud”
