Existing bitcoin stock will just split into smaller parts (= the BTC price goes up further and trading happens in smaller fractions).

If the network however becomes so bogged down that transactions take weeks, I'm fairly sure people will gravitate towards some of the other currencies; hopefully this is a gradual process, and the BTC price won't be affected too much / too directly.

It is not really clear to me, even after reading your comment. Can you spell it out? "Religious fundamentalism" is not in it self an explanation - why for example were Plato preserved and even venerated then?

>I do design research. My papers always provide principles with examples and evidence.

From what I remember of studying Human Computer Interaction (HCI) as an undergrad in the 90s, the evidence was derived from learnability studies. This meant that research favoured point and click interfaces (which are the equivalent of caveperson grunting, IMO) over command line interfaces which allow much deeper expressivity. There was basically no affordance to systems that people use day-in day-out and are happy with the trade offs in the learning curve (vi, emacs, blender, lighting desks, audio controllers, Bloomberg terminal).

I like that your example paper is about trying out different interactions in a small part of a daily-driver piece of software. But it's still trying a 'new' thing for some of the experimental users which means learnability is core. How do you manage the balance?

Thought it is not exactly same, but similar case is Where you pay Premium with Stock Options to have the right RIGHT to buy the stock one month from now.

Regarding cex & bitstamp they are exchange out side of USA, each of them have different Risk factors associated to each of those exchanges, that is why that price difference .

Coinbase and CBOE are both US based exchanges and are under govt. regulation and are reputable than any other bitcoin exchanges in the world.
If that's what you call helping, I don't want any part of it. I prefer not to be force fed garbage by Apple or anyone else. Why would society need a center that's formed of mediocre--at best--culture? Why shouldn't people be able to have their own opinions that are different from those of their "peers". Sorry, what you describe is rather nauseating and disgusting. If this is what Apple does, the less of it society gets exposed to, the better. This isn't helping--it's controlling. I'm not sure you understand what "helping" means at all.
While I have some sympathy for that position....

"Hello, can you have someone deliver this parcel for me. I'll pay you $5"

You're saying that if Amazon is asking that, they are responsible for the life of the person delivering it.

If I am asking Amazon that, therefore, does that make me responsible?

I think its perfectly reasonable to value a scare resource at a market rate. If the rate is too high to be tolerable then the government has an incentive to invest in water infrastructure. And people have an incentive to move where resources are under less strain.

Or we could just rape the environment for short term gain. It seems to be everyone's solution on every side.
So now the investors are going to lose out as companies take the hit of setting up new infrastructure in a hurry. You pays your money you takes your choice. Cost now or risk of surprise cost later. Not all investors are short-sighted (though I'll grant you that many are).

Thanks for making my point for me.

Every one of your statements is in some way a defense of the current mass media structure. Even your counterexamples of public news sources maintain a sufficiently small enough market share as would be counted as noise in a t-test.
> Investors try to build something while speculators just try to make money, no matter the cost to anybody else.

Based on your definition, what would you call Carl Icahn then?

I tend to agree with John Bogle's definition that both types of people are in it for the money, the only fundamental difference is the time horizon either is willing to wait to reap the returns from their investment.

[0] https://en.wikipedia.org/wiki/John_C._Bogle#Investment_philo...:

The main difference between investment and speculation lies in the time horizon. Investment is concerned with capturing returns on the long-run with lower risk, while speculation is concerned with achieving returns over a short period of time. Bogle believes this is an important analysis to be taken into account as short-term, risky investments have been flooding the financial markets.
Interactive Brokers is providing access to the CBOE futures to retail investors. Appears to be long positions only at the moment with high margin requirements, but it's something.

> The core contains 1e31 J of energy

What does that mean? Does it mean the core temp will drop to zero degree kelvin when 1e31 J is removed from it?

Can we realistically bring the core temp down to absolute zero? I think you need a temperature difference between a "source" (here earth's core) and a "sink" (here surface of the earth (radiation), atmosphere (convection)) to drive any engine. So geothermal energy stops being useful when this difference is zero or less?

Apple let a knockoff version of MyEtherWallet.com into the App Store
My reading of this is quite different from yours. To me he wants to 'share' the experience in the way he might that of a vista or a startling character. Not by giving you the experience (surely impossible) but by the literary stratagem of evoking an image of it in the imagination, by careful use of language. I think he's trying to pique interest or curiosity. It's up to the reader (if their curiosity is so piqued) to do their own work (whatever that may be) to see if related experiences might be relevant to them. I see nothing in this passage or in those of Iyer's works that I've read to suggest he believes anyone can attain the states he's describing simply by reading his writing.

There are certainly suggestions from other quarters (Zen, Sufism) that poetry in particular can sometimes (but rarely) trigger transient states of heightened awareness. But I'm not aware of Iyer subscribing to this.

As for analytical approaches to 'mindfulness', perhaps they're out there; I personally haven't done enough of a literature search to be sure. In a popular rather than academic vein, Sam Harris is probably as rigorous you'll get (he is always, at a minimum, very clear). Robert Wright (a secular Buddhist) has recently written a book whose title (Why Buddhism is True IIRC) strongly suggests persuasive (therefore analytical or at least purportedly rational?) intent, but I haven't read it.

But all that's a bit beside the point for most 'proponents' of mindfulness I have come across, because they are little interested in persuasion. They're not trying to argue for a Truth in the marketplace of ideas. They're just offering practices and associated reflections that might be useful to some. A curious party can pick these up and try them, and do as they wish from there. Persuasion really has no part to play.
Java and co can generate logic at runtime, go cannot so you have to manually write mocks, or "generate" them with a third party executable.

You cannot mock anything if you don't use go interfaces at first place, there is no inheritance in go so you can't swap types unless they are interfaces or convertible.

given an interface Fooer :

type Fooer interface {
Do(int)int
}

and a method to test

func Accept(f Fooer){
f.Do(10)
}

it's easy to write a mock

type FooImpl struct {
T testing.T
}

func(f FooImpl)Do(i int)int{
f.T.Helper()
if i!=10{
f.T.Fail("i=10 expected")
}
return 0
}

// the test
func TestAccept(t testing.T){
Accept(FooImpl{T:t})
}

Again, your methods have to accept interfaces at first place or you can't mock anything. With Go you'll often have to step back and do manually the things you took for granted in Java.

Only go maintainers can fix the "issue", by allowing the method definition on ad hoc structs, which is impossible right now.

Yes, and for Ice Lake they're introducing the yes-this-time-we-really-mean-it-fast-rep-mov, er, "fast short rep movs". Time will tell whether it beats a software implementation.

But my point still stands, if you're developing a new ISA, does it really make sense to add dedicated string copy instructions, using opcode space, adding die area for microcode ROM's, design and verification costs etc., considering that even Intel with all their money can't make them an obvious win compared to a software implementation?

But yes, both for x86 and RISC architectures, it's probably unwise to optimize memcpy() implementations by staring at microbenchmarks that do nothing else than memcpy() of different sizes, thus ignoring the I$ pollution that a monster implementation causes.
I really enjoyed this, primarily playing as the Tornado.

The main issue I had with the game was trying to get to spectator mode - it was a very short amount of time between respawns which was great, but hard to actually hit when trying.
I'd suggest either or both of a hotkey to enter spectator mode, or a button to spectate after next death.
Whether we like it or not, we are all gardeners. When you are young you won’t be able to see much of your garden, because it will take some time to bloom. Once it does take root though, you may find that you measure your success less in the things you do directly in your day to day job, and more in the gradual change that you cultivate around you. When I hear people panic about growing old, I feel that sometimes they aren’t yet able to see the roots that they have placed, and how powerful those are. If anywhere in your mind the thought has taken hold that life is over after 35, then wake up. That’s when the real work begins. Sometimes things will be easy, and sometimes they will be hell. When it’s your turn to face that hellish stretch of road, remember to smile.
A mock is a fake. Just so we are using the same terminology I'll define my terms:

Fake: a test implementation of something that stands in for production code to solve certain testing problems.

A fake can implement an API and provide simplified behaviour. A good example might be a piece of code that stands in for a hardware device driver that you use when you don't have access to the hardware. Another very common use of a fake is to fake out a UI layer. There are lots of other common places for pure fakes.

There are 2 special kinds of fakes:

- Stub: An implementation that returns canned data.

- Mock: An implementation that encapsulates an expectation.

The most common type of mock is a mock that encapsulates the expectation that a certain function is called.

Sometimes you don't want to write a pure fake because it's more than you need. Most of the time you can adequately test what you want without talking directly to some inconvenient real API with a stub.

There are many good reasons to use pure fakes or stubs. Like I mentioned, it might be because hardware is involved. Sometimes it's because you are using some SaaS that you don't want to really access in your tests. Very often it's because the real service is just too slow (I'll need another post to describe why this is super important, but even if you don't agree I hope you will see that it's not the only reason to use a fake or a stub).

As soon as you use a fake or a stub, though, you leave a hole in your tests -- you have no way of knowing that the production code uses the real service in the production code. This is when you need a mock. You can go without testing it, but mocking it in this circumstance is almost always a better solution.

Of course, there is a school of thought that reaches for mocks first. This school of thought is often referred to as the "London School" because it is very popular (and probably originated from) several very famous people who work in London. The GOOSE book, which describes outside-in programming is probably the best description of this school of thought. I've met quite a few of the people who are standard bearers for this school of thought and they are very talented developers. Again, I would need another post to describe why I don't think it's the best technique to reach for first, but it's an area where reasonable people can disagree.

Outside-in and promiscuous mocking has several advantages -- especially when you are less experienced. It provides a framework for reasoning about how to do design. Personally, I am not a big fan in general, but there are times I use it -- I just replace the mocks with non-faked tests after the fact.

So, while I agree that one should have the mindset to use mocks as a technique of last resort, it's still a valuable tool in your arsenal.

I loved those 1403 printers as a high school kid working on the IBM 360/65 at the Naval Electronics Lab on Point Loma (San Diego area).

Not sure why/how they hired me for the summer to do systems hacking (lost in the mists of time), but I remember adding some feature or other to the WATFOR Fortran compiler. (Maybe some additional COMMON features?)

There was something ultimately satisfying about the fonts used and the way a finely-tuned 1403 would render characters (even lower case on special models!).

Good design is thorough down to the last detail
Good design is environmentally-friendly

>No, they are not. The only thing to buy anything on iOS is the App Store, and it is not transferable - the only things transferable on the iOS Stores are, as both you and I mentioned, music (of course, excluding music bought prior to the no-DRM switch!)

I was speaking of the Mac. Who "invests" in iOS games, and would care to play them for years on end? For the huge majority, it's a casual thing.

Same with movies. Anybody who invested "four-digit-sums" in digital movies should just move on, like people did with VHS, DVD, and other early formats (and people had even more substantial collections there -- they had been burned enough times not to invest in digital movies). Besides, their "digital movies" already would look archaic in today's 4K screens (unless the service updates them).

>and it's not just Apple - I, for example, got my Amazon account blocked for unpaid bills back from a time where I was financially ... unstable, to say the least, and I literally have no way of ever getting that account reinstated and thus access to my three-digit-worth ebook collection!

That's a separate issue -- not being able to reinstate a rental account is crazy, especially if one doesn't only think of US, Japan, Western Europe and co, but the huge 70% of the world, where temporary issues with stability (in jobs, economy, etc) can often lead people to unpaid bills.
I haven't read that paper (Learned Index Structures), but things like gperf have existed for decades. Are these enhanced data structures dynamic, i.e. unlike gperf which is a static one, does it reoptimize as you insert new elements?

In the case of the hash table, I assume it's using the model to compute the hash function.

Clearly the better outcome is that criminals are arrested by the police using the appropriate and necessary amount of force, and then sentenced in a court of law. Having the police metering out and executing death-sentences on the fly is not a good idea, regardless of how "bad" the perpetrator is.

Or are you imagining a world where crime always happen in the open where police is around, so police by shooting at exactly the right moment can prevent violence or murder?
