See from the old discussion, I understand it's not about the branch prediction:

mgraczyk:

"I think It's because the branch target is a memory access, so the dcache causes the execution pipe to stall on the load. In the tight loop with a call, the branch target is a call and there is time enough to pull from dcache before the load data is needed. I suspect that the i7 can't pull data from dcache immediately the jne instruction, so you get a hiccup. Try adding a second noop in to tightloop as the target for jne."

"The CPU is using store forwarding to cache the 'memory' accesses in the store buffer, which means most accesses are not even accessing L1 cache (if this were the case, we would not have such a low count of cycles per iteration)"
Fascinating how all the "just use Litecoin" comments don't count the value of continuity of the UTXO set, etc.
I'm sorry, but like the other comment at the bottom, your guesses are so far from reality that they are hard to respond to. IACA is great for what it does, but it's a static analyzer and knows nothing about alignment. L0 doesn't even exist on modern Intel processors. Memory fences would change things, but aren't part of the problem as stated. And your guess that "it probably never even gets executed because the instruction should fit in instruction cache and branch prediction cache and all" just doesn't have any bearing on they way processors work.

Your disclaimer does indicate that you have the self-awareness that you are not an expert, but the fact that you are trying to make an argument would normally indicate that you think you understand what's happening to some extent. Rather than just guessing, I think you'd benefit from trying some things out and seeing what the results are. Play with perf, it's fun!
Yes! You had your alt account to check for blocks. I forgot about that.

Awesome history lesson, I had no idea how MIME originated. A few years ago (gosh I guess it's been like 4 now), I wrote a CORS-enabled MIME-type checker[1][2].

The main issue with MIME (which the article barely touches on, unfortunately) is that the type can be spoofed. It can be a dangerous attack vector and trust should never be given to external systems that claim x.jpg or y.mov is actually a "image/jpeg" or "video/quicktime."

Cash is cheaper for merchants, but people have only continued to use credit cards more. Further, if crypto becomes attractive from a cost perspective Visa will just be forced to bring down fees and stay competitive. It's pretty near impossible to imagine crypto with costs less than Visa's database.
This reads like an advert to me. “Cinemas are terrified of this!” is a good sales pitch.
For comparison in the other direction the world record 800m is David Rudisha 1:40.91 (2012). That's also ridiculous.
No, but it’s possible that his ideology matters more to him than other people. That seems to fit.
More than a lower temporal resolution (framerate), imposters are more often about a lower spatial resolution (2D billboarded asset instead of fully textured 3D model, or 3D model with fewer polygons/lower res texture, etc.)

There are also tricks using a lower temporal resolution - for example giving fewer ticks per second to the logic or animation of entities further away/out of sight.
This half-assed analogy falls apart under cursory examination; Lightning isn’t anything like a banking system because you have to trust banks and you don’t have to trust Lightning counterparties.
This is damage control masquerading as concern over the comments Chamath Palihapitiya made about how facebook is ruining society.

Anyone who has a significant other or kids addicted to facebook knows it monopolizes attention and affects relationships negatively.
What you're describing is a payment channel. The Lightning Network is that _plus_ protocols for negotiating the routing and chaining of payments across multiple channels.
I'm well aware.

I meant SecurID were fairly well established by the early 2000s for VPN access, from what I remember, so I assume they came around at least a few years earlier, which would be the late 90s, they also weren't the only option on the market.

Somebody still have to save the full chain. I don't think the idea is finally to have just one full copy of the chain.
It was obviously not complete in the form it was delivered, the "turning on" was supposed to be added somewhere at some later moment.

The whole thing is still suspicious: it was delivered to everybody whereas if it was supposed to be used only by the users who are aware of it, as now Mozilla tries to spin it, i.e. only to those who decided to "play the game", then the hidden install, especially to every user, was unnecessary as the normal extensions to Firefox are easily installed by the user, a click or two are enough:

I still haven't gotten a card from them, and I can't login to the system.

This exactly. Critical thinking, psychology, and interpersonal communication (with emphasis on building shared understanding) need to be explicitly taught in schools. We already have children memorize state capitals: they can memorize cognitive biases, mental models, meta-models/heuristics, empathy/communication techniques, and the a basic explanation of the psychology/neuroscience that backs them up. This will allow children to effectively deal with their own flaws, and those of others. Combining that with practical online/offline research skills and more hands-on experience of macro/microeconomics would leave children much more equipped to deeply and intuitively understand people and the world.

It's definitely not beyond their capacity either, all children figure out a smattering of these for themselves anyways, they just don't learn the names. Even the rather sharp ones only have a few more, or maybe one especially-honed one, but that's all it takes to make a big difference.

"A change in perspective is worth 80 IQ points" - Alan Kay

As an aside, children that develop significantly advantageous models early on often end up over-relying on them later, another potential-wasting issue we could avoid by making those children aware of what's going on in their brains.

Their website looked pretty poor. There were no clear terms or explanation of the deal. Are movies free or what price are they? Maybe they don't need to care because they already get so many signups?

I believe that the memo released was not an audit.

And I believe that if you want to prove to the world that you have a bunch of money then you should do a full, legal, audit.

That's the bar. If they have all the money, then a legal audit will prove them right.

I was going to say something like "is everyone taking crazy pills?", but I'll aim for a more serious response.

The problem is that people read way too much into what other people say. It sounds like you hear "partner? this person is clearly insensitive to the history of discrimination again LGBT people."

Instead try "I don't like the word partner, but it is a pretty standard term for not only the unmarried, but also married people. This guy probably doesn't understand it bothers me, but I'll give him the benefit that he meant no harm."
That is not true. Star wars is an exception and the cut percentage increased by 1%. The real reason is the dropping viewership. Number of tickets sold peaked in 2012. Beyond that the number of movie tickets sold dropped, however number of locations is up and salaries have gone up. To compensate for it, movie ticket prices need to go up.
I bet you could task the entire production team of Pulp Fiction with creating a movie, but without Quentin Tarantino it would never reach the same heights.

Studios take the bulk of the ticket price, and MoviePass is paying the full price of the ticket. Theater chains make the bulk of their profit on refreshments, so I don't think they're all that terrified.

MoviePass has to grow large enough to be able to negotiate deals with studios, like Disney, or raise rates significantly to cover the true cost of the service. If they raise rates too much, they could start hemorrhaging to the individual theater chain programs.

It's a cool service, but it can't last like it is.
>YouTube shows their intent to not infringe by the effort they put into removing infringing content.

I'd disagree, I think that Youtube shows their intent to allow infringing based on the gross amount of copyrighted content they allow on their website.
Where I live it would cost us $45 for tickets alone, probably $65 including food and drinks for a family of 3. I can buy a movie on iTunes for less than half that and watch it as many times as I want whenever I want.
When did prices increase? Did ticket prices go up in 2013?

Flex Box is similar to a ton of other layout systems, many of which I've either used or written in the past.

I have no idea why Flex Box feels so complicated. The fundamental idea is incredibly simple.

I can't offer much help, I've just spent (too many) hours fiddling with styles until I kinda get an understanding, I keep inching forward.

Super irritating given how simple the idea is in every other framework I've used it in.
"It took EU legislators more than a year of negotiations to agree on the legislative proposals, put forward by the European Commission in the wake of shooting and bombing attacks in Paris and Brussels in 2015 and 2016 which killed more than 160 people."

Is there any evidence that the shooting and bombing attacks were assisted by cryptocurrency anonymity such that the proposed new measures will mitigate?
Millions of tonnes of any waste released into the environment, no matter how "harmless", are too much. Humanity needs to tackle its waste problem, and that soon, or we are going to drown our kids in trash. Or, given that nitrates (which aren't that toxic per se) are the 3rd position in weight are perfect food for algae, we're drowning them in algae and without fish.

Not to mention that much of the stuff that gets released in huge quantities can actually be used as a natural resource. Instead of capturing and using it we're throwing all the stuff away.

Therefore, any way of looking at the environmental issues is good - anything that can be tackled should be tackled.
I just type a long string of random crap into the password field on sign-up and recover it with my 2-factor protected gmail account every time i actually need to log-in. In practise for the services I use this is almost never.

I prefer "Don't Sweat the Small Stuff" where self-help books are concerned. Also, my rule when dealing with others is don't mistake for malice that which can be explained by ignorance or incompetence. AKA give someone the benefit of the doubt.

And in the specific case you mention, I'll say as a gay marriage advocate, that someone who doesn't believe in gay marriage should not be forced to use terms they believe apply only to heterosexual marriages. IMO both of those people are entitled to their views and preferences and both need to agree to disagree. Without being disagreeable.
Actually, I'm with the second, not the first.

And so is my gay friend in NYC. It's just that he's scared that his boss is actually a passive-aggressive homophobe and he's going to get fired for politely insisting on "husband".
I think part of that mental toughness that may be overlooked is being dedicated and putting in the time to become a true champion. If you devote a good amount of your waking hours to a craft or sport and you use that time properly (learning to do things right rather than doing them repeatedly wrong) then you will excel.

I learned this from one of my Drumline instructors at university who was also a biology professor; He stated that one of his students did poorly on his exam and the student said he studied hours on end and didn’t know how that could happen. The professor replied, the amount you study isn’t nearly as important as studying efficiently and correctly. He then likened that to us practicing drums he said, if you spend hours practicing with improper technique then you are doing yourself a disservice and he finished up by saying you will only perform as well or likely worse than how you perform while practicing.

Despite that efficiency beats time in most aspects, if you want to do well at the National and international level you will still likely have to devote a very major part of you waking hours to honing your skills efficiently.
Are you including stopsigns in that, or actual steady state?

I think up to 15 or 18 mph is pretty easy pace for anyone who even road bikes once a week.
I'm surprised to see no mention of temperature here. The article says the temperature was 53f and "a little bit humid", and concludes with the Nike experts saying they disagreed that it might have been too warm, arguing that the temperature was perfect.

This flies in the face of much of what I've seen.

Alex Hutchinson wrote a wonderful article entitled "What will it take to run a 2-hour marathon?" in 2014[1], and in a subsequent piece[2] he lays out data from Paris officials who have found that the fastest elite runners did best with temps at 38.9f. This is a HUGE unexplained difference. Furthermore, with pacers blocking the wind more than ever, the Breaking2 effort would have given Kipchoge even less opportunities for evaporative and convective cooling.

"When French researchers analyzed the finishing times of 1.8 million marathoners over a 10-year period, they found that a race-day temp of 43.2°F produced the quickest times overall. But faster runners, who generate more heat, benefited from cooler temps, with the top one percent (green line below) peaking at 38.9°F. Midpackers (red line) do best in the mid-40s."

Yeah the famous '51% attacks'.

I read some of the online resources in the subject, including the one swinglock mentions[1]. And yeah the answers are a bit outdated, like the 2013 on: 'As for the merge, this is still being discussed and we do not have a good contingency plan'. The answer seems to be the 'longest chain wins' ... so that's not a 100% convincing answer.

Is there a way to know the distribution of nodes per country?

To build on this comment, the purpose of a currency is to facilitate the transaction of value, not to store value.

If an instrument stores value, it's an asset, not currency. One can of course transact business with assets, but it's a lot more complicated because you have to agree to a valuation. And without a currency, how do you measure that?

Plus, the incentives for assets and currencies are opposed. Currency exists to be spent, but if an asset is appreciating, you'll want to hold it, not trade it.

Bitcoin was advertised as a currency but it's acting like an asset. (And it's regulated like an asset.)

If you create a new class of asset, you can buy in early, hold on, and get rich on appreciation.

But if you invent a new currency? It's like inventing the inch. Even if everyone uses it, that doesn't give you any more length of your own.
I use it all the time - it's great!
Well, yes, based on a simple supply-and-demand model, that is what we'd expect to see. It's not what we're seeing in practice, though. We keep making immigration harder and harder, and it doesn't seem to be doing much to fix our economy -- certainly not enough to justify the real human cost.
Yes, it increased by 1% from 'The Force Awakens', which was last year (edit: 2 years ago, time flies) and also obscenely high. Don't say my statement is 'not true' then confirm it in the next sentence.
