This would actually make a terrific replacement for something like redis when you need a more structured schema.

The q language is very powerful, and expressive - interesting mix of lisp and APL. You can do really powerful analytics without writing tons of code for it.

You really have to see how fast KDB is compared to most nosql products out there.
So one of two things happens, either rates go up to pay for lost revenue of no roaming or rates come down as players fight it out and remove their competition.

Wow, great, now game developers can do something they have absolutely no desire to do, at the small cost of not being able to do what they need. I'm sure they'll be thrilled.
You are in a position of strength. You are making money. So solidify your position, sell it off or automate it, take the money and then go try the next thing. Many great companies that did change the world started as something completely different. Nintendo made paper trading cards.
This looks like a lot of words to disguise the fact it's neo-luddism.

With technological progress worker roles are eliminated, but the idea is that the market has demand for new currently non-existent things and as the progress enables those things to come into existence creating new jobs as it goes.

The much larger problem is people are genuinely getting conditioned to receiving a lot for nothing, and this has distorted the market in terms of what activities are most highly rewarded. For example, easy credit means selling to people that don't have the money (or the means) is actually very lucrative, so you get a lot of otherwise smart people engaged in activities to extract money from those with easy credit as opposed to applying their talents to contributing more positively to the system as a whole.
I agree it may be a modern idea, but I don't think you can really judge current policies on those of countries from 200 years ago.
That seems appropriate, since Judge did "Office Space", the finest documentary ever made about the tech industry.
I don't think you necessarily do, but I'm no expert in copyright law or typical contracts as it applies to paintings.

But I know when you buy a CD you don't normally get the reproduction rights as well, no matter how many or few copies were pressed.

But I agree that it would make sense, as I said. But, I also know "it would make sense" is definitely not a reliable predictor of what's actually going on when it comes to the music industry or copyright law.

And if this is what Wu Tang is doing... shouldn't we able to find them saying so in print? So I'm curious if anyone has.

Also, by "the good old days" I was referring to the medical practice of first identifying a disease's cause, then designing a cure. Most mental illnesses don't have this property, which open them up to exploitation by Big Pharma.
Strongly disagree, though I'd never downvote you for that.

Why did the US go to such great lengths to hide its involvement? You might answer that the US's checkered past in foreign policy (coups, assassinations, drug wars, oil wars, supported rebellions, etc) will make the world suspicious despite our altruistic intensions here. But I think the rest of the world's answer is simpler and more likely: our intentions are not altruistic, and this is merely another unprincipled application of power to obtain a goal. That checkered past is good evidence, and there's no reason this is different just because "social media" is a magic word or something. For example, why are we trying to undermine Cuba's regime but not Saudi's? Because our policy goals only pretend to care about dictatorships. And if we care so much about the Cuban people, why do we have a trade embargo against them?

Which is why no one trusts us and, frankly, shouldn't trust us. Building a platform that you'll use to "push them toward dissent" isn't providing a medium for free thought and reform; it's psychological warfare. We're trying to capture the attention of people and then trick them into doing what we want.

"So what?" you say. "Even if the goals are selfish and strategic, democracy is still good, and Cuba would clearly be better off without a dictator." That's certainly possible, but I doubt it. For starters, our involvement taints any actual emerging democratic movement with the notion that it's just another arm of US foreign policy. I'd like to live in a world where an asshole strong arm dictator can't blame "US meddling" for any unrest without being dismissed out of hand, but sadly, I don't live in that world. So we're really undermining that goal by playing directly into the (mostly correct) notion that the US isn't looking out for other countries' best interests. Maybe we should stop trying to interfere everywhere, because to the extent that our intentions are good in the first place, we're no good at it.

But more importantly, it's not really clear that actual democracy is the natural result of this kind of thing. If driven by US involvement, will a grassroots rebellion against the Cuban regime actually result in an open, honest democracy or will it devolve into a feeding frenzy for US interests, led by US-friendly politicians pushed into place by US operatives? The US has installed enough dictatorships and phony democracies for me to think this is more likely. When you use democracy as a veneer, I'm not sure why you'd expect it to really work.

HFTs do not see your buy order before it reaches the market and then buy them ahead of you to sell them back to you.

Your understanding of the stock markets and HFT is inaccurate and you are spreading incorrect information.
True, but not really relevant to this. Even if they were all the same, it wouldn't change things. The fastest would indeed win if all hashing devices started at the same nonce value and all incremented it in the same way. (the nonce is the extra data put into the block solely to make the block's hash meet the requirements) But precisely because of that, there is no reason for any device to try nonces in a deterministic way.

maaku's explanation makes clear a very good point - trying any particular hash only tells you whether that one succeeds or fails; it doesn't tell you anything about whether any other value will succeed or fail. Any particular hashing device will maximize its chances of winning/finding a solution by trying nonces in such a way that it is unlikely that any other device is trying the same ones, but that it never tries the same one itself twice.

I don't know offhand how many mining algorithms are out there and how they go about picking nonces, but I'd bet they do something like pick a strongly random starting value and then increment it by a fixed, small amount each try.

But yes, all of the miner's blocks are generally different. Each block that a miner is working on must have special Coinbase transaction that awards a specific number of new BTC to a chosen address. If you are an independent miner, that would be your address, but pool miners generally use a pool address. I don't actually know how the latest pool mining algorithms work, but I think they all have more elaborate systems for how payouts work.

Yeah, this could be a bad 10 minute SNL sketch or an amazingly awesome 15 minute "Whitest Kids You Know" sketch.
What else were they supposed to do when their next-door superpower blocked all trade, and brought substantial resources to bear on trying to undermine/destroy them? Invasion plots, assassination plots, every kind of wacky propaganda plot you can imagine (fake radio stations, leaflets dropped from planes), financial support for dissident groups, etc. etc.

My point was just that regular Cubans actually did alright, much better than US propaganda would have you believe, and better than most of the other states in the region, including those which were heavily subsidized by the US.

They could have easily ended up with a fascist police state or a civil war.

American policymakers obviously had legitimate reasons to fear anything that seemed like it might further Soviet interests, given the overall climate of the Cold War, and so as someone born in the mid 1980s I find it hard to judge their intentions and actions, after the fact. However, I tend to think that things would have turned out much better overall for everyone involved if we had kept up diplomatic and economic relations with the Castro regime right from the start, instead of basically forcing them into Soviet arms.
1) Chris claims "The fact of the matter is that HFT’s can’t rip you off.". Front-running[1] is an example where HFT's do rip people off, simply because they didn't know it was going on. When the performance of institutional investors is harmed in this way that harms everybody with savings or a retirement fund. Not just the guys at wall street.

2) Straw man.

3) Yes, while we're at it let's change the subject to photo sharing websites instead. That sounds reasonable.

Edit:

[1] Again referring to the technically legal version of "front running" as used by Michael Lewis where HFT abuse buy/sell orders arriving at different times at the exchanges.

Telemarketers. Door-to-door cable TV sales. Most of the paper-pushers in the USA's medical care system (assuming we go to single payer system as well). A large percentage of retail workers (in the USA we have way more retail space than is really necessary). Most of the mid-level managers in most of the large corporations. Any place that has strict union work-rules is usually overstaffed to my eye.

Much of the administration of social services (Social Security, Food Stamps, etc.) in the USA (to all be replaced by that basic living stipend).

Some time ago, I was suffering from several months of severe depression.

Out of desperation, I obtained some Ketamine. I carefully measured a dose that was somewhere between theraputic and recreational.

I had the experience of seeing myself in the third person, as a narrator: "look at him," I said about my body, "just lying there on the couch."

Time passed and I returned to my normal awareness.

There was no noticible effect on my depression. Many months later, it gradually abated.
It's true that this is an old misuse. But IMHO it's still deplorable that a word and its antonym have merged into one.

imgur has had voting, comments and it's own little community for a while now. It could cannibalize the image macro based subreddits (like /r/pics /r/funny) which drive so much traffic to reddit.

imgur is also not getting as much money as it could from reddit because links are posted directly to content bypassing the ads.

I wonder how much longer the synergistic relationship will continue to exist.

Cuban-American here. Helping Castro's controlled economy before giving control of the government and said economy back to its people is unpopular. Allowing the Cuban people to communicate and band together within the country is attempted all the time by government-affiliated and independent organizations, most of which are in Miami and organized by Cuban-Americans. This seems like one of those attempts, sponsored by the USAID Office of Transition Initiatives[1]. If I were in charge of the project, I figure I'd probably also avoid giving this project a U.S. brand as to not catch the attention of Cuban censors or propagandists.

Networks are fully controlled by the Cuban government. Their "Facebook" is government built.[2] There are no social networks that are optimized for the tools (like satellite phones) they use to get around censors. At first glance, this seemed like a nice attempt at helping the Cubans get around these limitations.

They don't. "Creating liquidity" is the weasel term they use to justify making money off of trades that would have happened anyway without their help.

The trade clearing systems themselves create all the liquidity that anybody needs.

If anything, they insititute a tiny tax on larger trades, such that there is a tiny deadweight loss to the market every time they front-run somebody. It isn't enough to be very noticeable on a single asset, but it is a positive and nonzero amount that is destroyed each time, and that can add up. To what, I have no idea.

You need others to validate your beliefs, then impose your beliefs on others. So you can believe these made-up beliefs yourself. In rare cases you can believe yourself if no one agrees to you. How fragile we are as humans.

I contribute to the Doppio JVM project (https://github.com/int3/doppio), which we initially wrote in Coffeescript. About 9 months ago, we decided to port the whole thing (~10kloc) to Typescript, and it proved really useful:

- Typescript is a superset of Javascript (mostly), so we ported by converting all the Coffeescript sources to Javascript and renaming them with .ts extensions. There was a bit of cleanup involved in getting modules to play nice together, but most of the code ran without modification.

- The JS that the Typescript compiler generates is much easier to read, in part due to less "magic" in the language.

- It also makes performance much easier to reason about, for the same reasons. One issue that bit us several times was Coffeescript's auto-return feature, which was invisibly accumulating large arrays of values from our interpreter's bytecode loop! This is no longer a concern with the current Typescript codebase.

- The inner workings of the JVM are fairly complex, so enforcing types at compile-time actually does catch bugs before they happen.

USAID is an arm of the US intelligence community. Every US embassy has a CIA Chief of Station. That most USAID employees and cobtractors are sincere and not officially or knowingly spies does not mean that they can really be trusted. They're agents of a foreign power and they're in your country to further its hegemony.

Remember how they found bin Laden? If they'll use a vaccination programme as a front to spy they're not going to take the "independence" or "mission" of USAID seriously.
..and the right-wing juntas up and down latin america were subsidized by the US. Cuba still did better.

You could say, "But that's not a fair comparison, the USSR subsidized things that actually helped people in Cuba while the US only funded commando death squads and fruit exporters, of course Cuba had a higher standard of living".. at which point I'd ask you to review what you just wrote.

I like games very much, but the idea of gamification eludes me.

This gamification stuff looks nice and sounds plausible, but it's just a model of self-evaluation.

Since it is just a model of your state and not your real state, it's always opened to be "gamed" (pun intended).

It's the same stuff managers do to people all the time. There are some criterias and you have to meet them to get your promotion. Many smart people think "well I can get good 'for real' or just be good enough for the system... but I think the last one is easier".

Gamification is the same, it just looks modern.
You do know that the skepticism you have about news articles on April 1 ought to be applied on every other day of the year, right?
1) It's debatable whether you can call this behaviour "abuse". It's also debatable whether you can call it "front-running". The HFT has an advantage over the rest of the market, which is that they're faster. They're faster because they've paid for faster connections and they've hired expensive developers to build fast software. They then use that advantage to propagate information between exchanges more rapidly, so that they don't get picked off by informed traders on other exchanges. The basic mechanism is exactly the same as any other market making, it's just that it happens faster.

Let's say I'm a big investor in 1960 who wants to buy 100,000 shares of MSFT (yeah, they didn't exist back then, whatever). I call up a floor broker who's standing on the trading floor at NYSE and he quotes me $49-$51 (because it's 1960 and you can drive a bus through the spread) but he can only offer me 50,000 shares. No problem, I buy from him at $51 and dial another broker at BATS in Kansas (also didn't exist in 1960) to get a quote from him too. But in the time it takes me to dial the number, the news of my trade is wired from NY to Kansas and my broker there has put his prices up in response - he now quotes me $49.50-$51.50.

What the hell? I thought it was $51 to buy? Well, it was at the time I made my first trade. But when you want to make a big trade, you don't get it all at the bbo. You expect your trade to move the market.

Exactly the same thing happens today, except that it all happens in milliseconds rather than minutes, and the spread is $0.01 instead of $2. Voice traders at banks and other big institutions (at least, the ones that didn't already adapt years ago) are getting hissy about it because they want to be able to buy everything at the prices they can see on the screen, regardless of liquidity considerations, and also they'd like a pony thank you very much.

2) 'Regular people' are not putting in orders that are large enough that they need to be routed to multiple exchanges. If I send an order for 100 shares of MSFT, it won't go anywhere near an exchange. It will get filled immediately, by my broker, at essentially the national bbo.

3) Yup, it's totally valid to ask these questions. In fact I think it would be great if the HFT industry was more transparent, and I fully expect that to happen. But that's not the same as saying that the market is rigged or labeling totally standard market-making behaviour as "abuse".
As an European from the Shengen Area, I never really considered the UK a part of EU.

London is 2H30 from my home (Paris), but I found going to Roma or Barcelona more easy, since I don't need any ID (and don't have to deal with customs and the induced delays).

I board the train on the evening, and when I wake up I'me ready for a week-end abroad. It's also cheaper, but that can be explained by the technical feat required to create The Channel Tunnel.
You can watch HBO on any computer/tablet/smartphone plus Roku and Apple TV using HBO Go. (I hate to sound like an advertisement here. I'm not a customer of HBO Go, but it's worth noting that they were actually one of the fastest cable TV companies to put their content online.)
What scale would you use? If we choose 15 minutes, then day traders who sit at a computer screen all day have an advantage over people who have to work.

Ok then, how about once a day. Well then people without kids have an advantage as they have more time to research this stuff.

Not to be overly sarcastic, but you can't pick a discrete time period that doesn't have trading speed as a component.
First issue is relevant only on systems that have more than one NUMA node, which is probably every meaningful physical server and essentially no VM (at least on Xen, multiprocessor VMs are single NUMA node), as it does not make much sense to advertise NUMA topology to guest VMs.

Second issue is relevant for postgresql mostly only if you use very large shared_buffers which anyway is not recommended for general workloads. Writing page that exists on disk and was not read short time before is not especially common thing to do.
