Coinbase has a history of canceling orders placed at lower price if the price spikes to a higher level. All other companies honor prevailing price at the time of order.

Top that off with Coinbase's buggy automated KYC system, hackable 2FA, and lack of customer support, and it makes me wonder if this is the best that $140 million investment can deliver?

While it's generally not a good idea to try the visa on arrival option when you can't get a normal visa, the transit visa isn't just for transit as such.

"To accelerate the strategy of “Development Driven by Innovation”, sanctioned by the State Council, as of January 30, various ports of entry in Shanghai [...] are to implement a 144-hour visa-exemption transit policy [...] First and foremost, the length of time for visa-exemption stay is extended considerably. With the previous 72 hours doubled, foreign passengers would have ample time to conduct short-term activities such as businesses, sightseeing, visits and exhibitions while in Shanghai."

No it doesn't; that is just a broad principle that is inapplicable in many specific situations. For example, any of us here could offer an opportunity for very low returns at very high risk, it just wouldn't amount to an attractive proposition to a thoughtful prospective investor who understood the offer.

I don't get it. Coinbase is more costly than using the underlying exchange directly. Is that unexpected? It's a convenience service. There are costs to this convenience.

The $2 "fee" looks like a 4% credit card payment processing fee, pocketed by Stripe or the likes, not Coinbase's fee.
The Koch brothers are pro-choice, as far as I know.

Do be careful with Forex.

Lots of shady stuff about and what many people don't realize in many (most?) cases of consumer internet platforms (like FXCM), one is actually trading against the company (they are the market maker) not against other participants. Not saying what does or doesn't happen, but the situation is such that there is incentive to do things like widen spreads and hit stop losses.
Bitcoin. It's only a bubble after it bursts.
That aside, it's interesting to see Stanford on Medium. Maybe Medium is doing better financially?
It's a little different because the competitor does not want the digital assets being hacked, but rather just wants the hack to be on record.
So you buy a receiver will never watch the channel, yet you must pay whether or not you even agree with their programming and somehow that is voluntary excise? It's strongarming.
The market is very volatile and there is probably significant spread between buy and sell. Most exchanges (any currency, not just for bitcoin) will earn some revenue through the inevitable spread. So if spread is large, then shouldn't fault coinbase for filling those orders accordingly.
I don't know about this implementation in particular, but in general a cons cell is just an object with two slots in it. You can use it to represent a list (by putting another cons or nil in the cdr), but you can also use it to represent other things. For example, a pair, by putting an arbitrary object in the car and cdr. This is a pretty common technique, see "a-list" for one application.
Looking forward to Rachel Maddow's monologue tomorrow night on "dark money in politics".
> solar is still stupid cheap.

Addendum: and getting cheaper.

> It just needs financing.

I would just like to make the point that this is actually the greatest pain point now. Solar is not getting financed exactly because it is stupid cheap and getting cheaper.

Think about it: will you be investing in something that's already stupid cheap (with bad margins, and heavy international government competition making it cheaper), and getting cheaper ?

That would be a VERY bad investment decision.

So what's happening is "the datacenter investment". Solar power plants are mainly being built and financed by the customers of their electricity, who use it to disconnect from the grid (to some extent). Nobody's investing in it, because it's not necessary.
They are already charging a transaction fee, why should their execution price be above market?
The author mentions that they only analyzed the collection of C# repositories that they used in their study on Singletons, but I would expect the results to be different depending on the language used.

In my experience with Python, unit testing is essential to catch careless errors (typos, bad ducks, etc. that can't be caught by a linter) that would cause your program to crash at runtime, so there's a slightly different motivation for writing unit tests. It's a less restrictive language so you don't have the issues with private methods like the author mentioned, and is (at least to me) a bit less of a strain to write tests. Unit testing might correlate more with good hygiene for a Python codebase because testing is vital to check correctness and there are fewer situations where you have to mangle your code for the tests, whereas it may not in C# because you get guarantees from the type system that makes testing less vital and writing tests is more of a nuisance.
If we had a valid answer to your question we would already be rich. There is no answer. Though, I'd look into bitcoin as a very risky investment today. Who knows? A bitcoin could be worth $20000 in 6 month. That's the only doable/crazy thing right now I could think of. 3-6 month is too short unless you go hard on day-trading and get super lucky trading futures, options, etc.

You don't have to be completely binary in your judgements of people like the Koch brothers. They can still be politically questionable even if they do things you agree with from time to time.

For instance, their views on criminal justice reform would probably be quite favourably received by many of the same people who oppose their views on climate change. That isn't a contradiction unless you make it one.
>>Regardless of what you think of the Koch brothers, this appears to be a mundane deal sensationalized by the specter of the Koch brothers.

Of course, until 5 years from now, they simply frown their faces about an article and editors get the message.

"I picked up the phone and called Murdoch and said that I was speaking not as a shareholder, but as a viewer of Fox. I said that these are not Muslim riots, they are riots," Campaign Middle East magazine quoted the prince as saying.

"He investigated the matter and called Fox and within half an hour it was changed from 'Muslim riots' to 'civil riots'."

Some years ago I spent a few weeks trying to develop absolute pitch, and I made enough progress to see that it was possible, but that it would also take a lot of time and effort better spent improving other aspects of musicianship. To have absolute pitch early and effortlessly is a huge help no doubt, but it would add little value for an already proficient musician with strong relative pitch.
I'm a heavy proponent of writing tests - even if it's not full-on TDD - at work, to the sometimes annoyance of my co-workers, and my reaction before even reading the results was that for those two, his prediction was wrong.

It seems obvious to me: If you have (good) automated tests for correctness, a method can handle more complexity without the programmer needing to handle all paths in their head at once. The tests should let them know if they made a mistake somewhere. On the other hand, if no such tests exist, those methods would be more likely to be written as smaller methods that call each other (maybe one "driver" and a couple "helpers"), so the programmer doesn't need to hold the whole thing in their head at once.

The odd part is that the second way can often be better for clarity/maintainability, since those helpers can be reused and the driver can be written at a higher level. But it seems like automated tests give people an out where they don't have to think about that anymore.

To add upon your comment, the moon could also act as an interplanetary shipyard. With the low gravity and stablity, as well as proximity to earth for raw materials and man power. Assuming it isn't completely automated.

Iirc, Isaac Arthur (I know him as a sci-fi YouTuber) has done numerous videos on how we could become an interplanetary/interstellar species. One of those videos covered the use of the moon to those ends.

The point is sometimes copper connections are the only options for voice and data. And now ATT and friends can stop servicing rural / small communities.

I live in a small community an hours drive from San Francisco. There is only ATT DSL. (no cable, only a couple cell services and none at all for some - including myself -
due to the hills and valleys)

I am lucky and have DSL (5Mbps, and most of the time really 2Mbps, barely any upstream and it slows the downstream to a crawl when using it - example: watching youtube on 240p setting freezes when checking your email).

Many in my town have been without home internet for years. And even if you have cell coverage, the 10G of tethered data per month (that is what Verizon "unlimited" is) - can be eaten away in a day by a person not realizing their computer is updating or watching netflix on 720p.

There was once a healthy ecosystem of local ISPs. the big players killed them and now those healthy ecosystems will need to grow back. But it will be painful for those who have to go through networking withdraw.

Yup, I've had this happen WAY to frequently with the DG1670 CableOne forced me to switch to (and I literally have no option for other equipment, they require this specific modem for anyone with a static IP). The modem will literally lose connection and reset itself when under load (which takes upwards of 10 minutes to boot), if I could put my old SBG6850 back in place I would do so in a heartbeat.
They are all problematic, but an additional issue is that Conservative views tend to be labeled such more then Progressive views get labeled such -so the presentation is that Progressive views are more "normal" than conservative views. As in your post, you're implying that most of Murdoch's outlets are politically biased but make no implication about progressive outlets.

One neat trick with .NET on Windows, is that you can actually export static methods in assemblies as unmanaged entry points. In other words, things can LoadLibrary/GetProcAddress them, and invoke them as native.

C# doesn't support this out of the box, but it can be easily done by post-processing the generated assembly. There's a NuGet package for that.

I'm not sure if any of that works on other platforms, or with .NET Core. Probably not.
What this guy is complaining about is effectively a 0.24% spread. This is directly from Coinbase's site:

Your exchange rate for buying or selling digital currency through our Conversion Service is calculated as the market rate of the digital currency on Coinbase’s GDAX platform, plus a spread between 25 to 100 basis points determined by the size of your transaction, market volatility and length of time using Coinbase ("Exchange Rate").

Your biggest Problem there is psychological strain if the 100K means a lot to you. You will at best have a miserable time and at worst panic sell in the wrong moment.
So if you cant afford to lose most or all of the 100K dont invest it especially not in high risk products.

Walkability only applies to the small set of rich people who live in the most expensive part of the city. Growing up in the suburbs, we'd frequently visit family friends clear across the metro area. It would take at worst 15 minutes to drive to and park at their houses for dinner parties. The geographically closest person I know in San Francisco is around 2 miles away, and that's 40+ minutes on foot or more by bus (off commute hours so low frequency, no express service, etc).
Yes, you're right, it is unfair to not consider the many subsidies that entrenched companies (automotive or otherwise) have received and currently receive. If the LAT were to count up the ones for GM using the same standard they did for Tesla, it may very well end up being a similar magnitude of subsidy.

So I suppose the main thing GM and such companies have going for them is that they have a track record of being profitable and they would likely have a stronger chance of remaining profitable sans subsidies than Tesla. But I realize that argument is basically begging the question, if not an outright tautology (Wealthy companies are wealthy).

Furthermore, it's not at all destined that if Tesla got into a failing situation that U.S. politicians would feel an obligation to keep pumping them up, or to bail them out, especially in an Trump administration. And Tesla can hardly be blamed for taking advantage of publicized subsidies, it's no less sneaky than the way entrenched companies have taken advantage of those subsidies for decades, nevermind tax loopholes and shelters.

So I'll weaken my argument to this: Tesla's inability to make money is not, as the OP suggests, a non-issue for Americans. Tesla may be no different than any company in using tax credits and subsidies, but the fact remains that if Tesla fails -- a much more likely situation in terms of the near future than it is with most of the other car companies -- those tax credits/subsidies will have been greatly wasted. Because think about it: if Musk could effectively deliver on his technology ambitions -- I don't mean prototypes, but implementation and successful production -- in what likely economic scenario would a good-acting Tesla continue to be bleeding money?

In other words, at some point -- not this year, maybe not in the next 5 years, but also not never -- the lack of profit might be a signal that there is something fundamentally wrong with Tesla, either in its goals or in its internal workings. And claiming to have or actually having grand, life-improving ambitions means jack shit.

Would the OP have written this kind of piece of Theranos?

You should read the article, and my comment, a little more closely before responding. You're making a massive, unwarranted leap from "not a universal evil" to "must not have any legislation around it". I also don't think cars are pure evil....do you assume that I think that cars should be 100% unregulated? I'm specifically complaining about the maximalizing tendency of the author and others on this post: casting Facebook use as a pure vice, and ignoring the millions (hundreds of millions? I have no idea) of people who are able to get a very positive cost/benefit out of responsible use of it. Your cigarette analogy is apt in that I think that way of tobacco: I have a cigar a few times a year, and I think that the notion that tobacco is some evil force that we have to ascetically shy away from is idiotic[1].

> Which, by the way, is an awful metric for whether something should be banned

Dude, seriously, _what are you talking about_? At no point did I mention anything about banning Facebook or anything else. I don't know whose post your comment is supposed to be responding to, but just FYI you clicked "reply" under mine for some reason.

The point I am making is that "Facebook use" and "unhealthy Facebook use" are not the same thing, and the tendency I am criticizing is writing articles about the latter and bait-and-switching them to be about the former. I can use my phone to call a drug dealer, I can use my car to hit a pedestrian, I can use my computer to harass people online: and yet nobody considers those to be indictments of the overall concept of phones, cars, or computers.

Leaving aside the fact that your cigarette example doesn't make any sense:

Which cigarette legislation in particular are you thinking of? I'm of the same mind as the rest of society when it comes to kids being protected and having less autonomy in their decision-making, so not being able to advertise cigarettes to kids is obviously good. I'm not opposed to Pigovian taxes to balance externalities, especially when harm scales with amount of use and has significant enough externalities (like second-hand smoke), so the taxes on cigarettes don't bother me either. I think that there's some scope for paternalistic legislation of activities that don't harm others, but I think the bar has to be pretty damn high and pretty damn robust for that.
Question as I'm not a "hacker" and don't claim to be, but what are the worst possible case scenarios with hacakable 2FA outside of individuals getting screwed over as opposed to the platform itaelf becoming unstable? Secondly 2FA has never claimed to be 100% secure by any company unless coinbase is promising to be the first company to do so? That is my understanding but if there is something particularly vulnerable about coinbase or gdaxes implementation of 2FA what is it? I know you can set up multiple forms of backup but I use Google authentiactor which becomes just about as vulnerable as who can get into my phone depending on where I leave it if I lock my phone if I lock the app etc etc just like any other form of 2FA? I'm genuinely curious as I am just learning about encryption in my spare time but by no means an expert.

Regardless about coinbase being insecure in general
I was looking/curious about the bug bounties coinbase has been offering (and for gdax too as they are under the same company umbrella) and the highest bounty bid range that has been claimed is $5k but they offer up to $50k in bug bounties up to remote exectuable code for gdax.

As far as the $140milliom, coinbase/gdax are hiring multiple positions for backend gdax senior engineers and other support. The recent infusion of $140million is only from a few months ago so I'm pretending the money wisely and hiring high quality people doesn't happen overnight.

Secondly, alot of the funding has been spent on fees for liscensing in NY as coinbase continued to pull through as multiple other platforms pulled out of NY when it became nightmarishly expensive and overly complicated to deal with relative to every other state.

Finally, as coinbase is one of the few maybe the only besides one or two others that is liscensed in NY that means wallstreet is trading on it, so the spikes are definitely subject to be exposed or show other latency issues on the platforms that are legal for people to use, now that multiple banks have come out and acknowledged they are trading with BTC.
The rest of this thread is a sad excuse of analysis of the problems with the Koch family, but I just want to say it's not worth pretending the BBC isn't just as bad as the equivalent here, which would be NPR, (so don't go trying to compare it to fox or MSNBC) and I've heard plenty of criticism of British media doing exactly what you say they don't, from one of my favorite and one of the best journalists, Robert Fisk.
You're wrong, and that's exactly what "unsafe" block does in C# - it does not affect the outer blocks. So, for example, if you wrap your pointer arithmetic inside "unsafe", you don't need the "unsafe" modifier on the method. If you put the modifier on the method, then you don't need the modifier on the class. And the code that uses your "unsafe" classes and methods doesn't need to be
in "unsafe" context.

If it were otherwise, no C# program would compile without "unsafe", because large parts of the standard library core (stuff in System) is unsafe. The only reason why "unsafe" is useful is precisely because it lets you isolate unsafe operations in a way that lets safe code invoke into them (assuming that you uphold your safety guarantees).

The /unsafe switch is a different thing - it needs to be turned out for the C# compiler to allow "unsafe" anywhere in its input, and is basically a project-level declaration that "this has some unsafe code somewhere in it".
