Wouldn't that depend on what you want to achieve? To maximize $/h you need to understand your opponents weaknesses and exploit them.
But if you just to beat the best humans, and don't care about the margin with which you beat them, then playing a mathematically perfect game should be enough. And before you ask, a mathematically perfect game can incorporate occasional bluffs, and occasional calling of bluffs, this would be known as a Mixed Strategy.

Or am I missing something?
I disagree. They show spring-type applications, things precisely going back to alignment, etc. Industrial engineers should be able to take these higher-level concepts and put them in their toolchest

WE are richer, you are not.
Either that or 'Lord of the Flies'.
Yet curiously the middle and lower class enjoy a higher standard of living today than 30 years ago. It's almost as if GDP/income aren't an absolute measurement of, well, anything.
This looks great! But could it be modified to work off of an Apache Solr backend instead? If not, do you know a similarly nice group of front-end components for Solr?
What? Do I have an obsession with writing paragraphs or looking at source code? What you are saying doesn't make sense and doesn't engage the conversation. Instead you are being needlessly hostile.

Besides, even if I did have an obsession with reading source code, it would not have any bearing on the usefulness of expecting version history in general. Here you are talking about me which makes pretty much zero sense, whether I am obsessive about it or not.

It's important to write a lot about this because the nature of your comments borders on unstable hostility. Even if you disagree with what I am saying about version history, and even if you disagree with how passionately I feel about it, I still deserve better than to endure petty insults that literally have nothing to do with the context of the conversation.
My point was that the problem is NOT easily solved for the typical user.
We know that because it is rigorously proven within some axioms. A large, but finite, set falls into the given axiomatic system where it applies, so we know.

If you're going to start questioning whether math is real (is the whole universe just a dream type stuff) then sure, do that, but don't try to apply that for math which such fuzzy junk.

There is a world of difference between infinite and finite. "large but finite" is not in any way comparable to "infinite". Any attempt to make such a parallel between infinite and large finite is fundamentally flawed to begin with.

The pigeonhole principle has been proven and it's by that proof, and the history of math it relies on, and the fact that that math has a higher predictive power than anything else (especially within its own axioms where it's p-much perfect!)... that's why we really know that it works.

If you want to question whether it works, then the burden is on you to provide evidence of some form more than some misguided "feeling" that large numbers are relateable to infinite. There already exists an argument in the form of the original proof and it is your burden to make a more compelling one.

Also, I'm not sure why you're saying that the principle breaks down with infinitely sized sets. Infinitely sized sets.. Firstly, if both sets are infinite (and your plurality of sets there indicates you mean that), then it doesn't apply at all since m = n. If the sets are of different orders of infinity and you can, in fact, create a bijection between then then it does still hold.

However, you state it as "a set and a set with one more element" and then say "infinitely sized", which when combined reads as complete and utter nonsense.

Basically, I think you're starting with a flawed premise, leading into a flawed question, and there is no good answer.
Pigeons were once used to cheat in the lottery in England. I don't know the year, but I'd imagine it was before the telegraph. But it used to be that you could still buy tickets after the draw had been made in London - the results would travel by horse, but you could use a carrier pigeon with the lotto results to outrace the news.
Cool. Thanks for the links. I used to have a genuine Casio years ago and loved it. Ran for about five years on the same battery. Wanted to buy one again and almost bought one online.

I've always kinda hated "Freakonomics" - albeit irrationally. It just never felt like the author truly understood the difference between correlation & causation.
The industry is insane for creating potentially dangerous all in one interfaces given the carnival circus of the supply chain.

As a lot of people have mentioned Lua ITT, there's a library called Pluto[1] which can serialize coroutine states. It was used in the game Fable to store quest statuses[2].

It's not always the case where smaller armies lose to big armies. There are many situations in Starcraft where superior micro of less units can taken on more units. One example is Phoenixes versus mutalisks. For those who don't play, Phoenixes are faster and have slightly longer range than mutalisks. Phoenixes can infinitely shoot and run and kill of mutalisks.
In the 70's a friend of a friend of mine developed Adventure which I'm sure you all know as the original text adventure game. It was a giant step in computer games. I worked at HP and someone ported it to the HP minicomputer. It got so popular they had to run a script to block it during work hours.

My wife and I came in every night after dinner for weeks and played it. When we weren't playing it we discussed ideas to get past the block. The word play was awesome.

You are making a strawman argument, I didn't say "the public" meant taxpayers, I was talking about the "the public" in National "public" Radio and the "public" Broadcasting System, and the federally funded Corporation for "public" Broadcasting.

And in any case, your clarification is baloney, you are either being fooled by NPR's accounting sleights of hand, or you are helping to propagandize it. Federal money does in fact flow through public broadcasting's network of "shell" companies such as the Corporation for Public Broadcasting to local stations to and then to NPR. Here is an article on PBS.org about Congress potentially cutting funding to NPR. http://www.pbs.org/newshour/rundown/us-house-votes-to-cut-np... Yes, that was 2011, but the same baloney about NPR not receiving direct federal funding was the story back then too.

In any case, my argument that the works of public broadcasting belong under a creative commons license is referring to the same public that the stations bray about endlessly, "you the listener".
Fair enough, and there is an order of magnitude between size of the the 7030 and supported ICE parts (125K cells vs. 7680 cells), so it's beyond optimisation.

Out of curiosity, is there any one block/function that is consuming a majority of the cells? What is that block?
Well, anyone who says that advantage in micromanagement is not a big thing should see "Automaton 2000" videos. Given that automaton is a map script and thus can have virtually unlimited APM, it beats people from a horribly disadvantageous positions (40 banelings vs 21 marine [1], or 100 zerglings vs 20 sieged tanks [2]).

The complexity of the unit interactions also has a strategic layer (drafting, lane assignment, timing) which may be far more difficult to train and isn't just purely the micro aspect of the problem.

Hauser's law, that states that federal tax revenues since World War II have always been approximately equal to 19.5% of GDP, would suggest that tax levels are similar as a percent of per capita GDP.

Yes! To a large extent the visible nature of digital technology is a reflection of the capability of people to take advantage of it.

If we never progressed past the Commodore 64, we could still be discovering advantages and uses for it. As it is, new tech is coming our way far faster than we can effectively apply it.

Or, to rephrase, a lot of office work could be completely replaced by a basic excel spreadsheet macro, let alone machine learning and the latest neural networks.
Death cap survivor story: https://blog.mycology.cornell.edu/2006/11/22/i-survived-the-...
Wikidata did a comprehensive analysis of Graph DBs [0], and settled on BlazeGraph with TitanDB coming a close second.

Notably, there are quite a few omissions. DGraph and Cayley [1] being two of those. Interestingly, both are developed by Googlers. Cayley is used by Kythe.io [2], a Google project that kind of competes with srclib [3] by SourceGraph.

Cayley has native JavaScript interface, which makes it an interesting choice for Node JS based apps.

At work, we settled on TitanDB, primarily because it supports DynamoDB/Cassandra for storage and ElasticSearch. Most of the graph DBs rely on some storage engine or the other underneath-- Cayley supports LevelDB, for instance; whereas TitanDB supports BerkeleyDB apart from aforementioned DyanmoDB and Cassandra.

If someone consistently misrepresents facts, that's one thing. If they constantly produce content and sometimes fail, that's another. Freakonomics is cool for new ideas, but if you really get excited by something they publish, it's worth doublechecking. I don't think discounting them as gossip based on one article is the right solution.
There's no "policy" to this research
Suppose a DJ using a counterfeit charger bought from a 3rd party seller through Amazon burns down a nightclub, killing 100 people.

Who gets sued in this case? Everyone! At the very least: the DJ, the club owner, the city, Apple, Amazon, 3rd party seller, maybe even UL if they are not aggressively protecting their logo.
The way they talk about their Dynamic Random Level Generation suggests they probably already somewhat developed it (and probably other aspects of the game) as a proof of concept.
It's pretty trivial to load up an epub file (or a few other formats, IIRC) onto the device. It exposes itself as USB storage, so you just mount and copy your files over. There aren't as many fancy features like position syncing, but it's definitely a great piece of hardware even if you don't want to use Amazon services.
Is this any difference to a platter of Hard Drive, under magnifying glass?
This looks very promising!

Are you planning to add filtering, supported by indexes? Seems a bit useless for production use if you can't filter a query by predicate, or even sort/limit. You could layer something like Elasticsearch on top of it, but then you lose all the graph support.

Any thoughts on enforcing schemas?
This is one example of a pervasive problem of the 1-bit social ecosystem or what I call the "like-only problem"

It's partly a technological problem and I really like this approach to that side. (one missing item would be nulls or no-opinion on one or more dimension)

The other more pervasive problem is the business problem if you will. So much value is in the first bit of the edge of the graph, that getting incremental bits onto each such edge is diminishing returns. Especially in venture land, the name of the game is mindlessly adding nodes and edges. It is rational for the graph owner because that's the way to grow value fastest, and because more dimensions or bits on each edge makes it all a lot harder for humans (think ad buyers) to grok.

A related issue is that from a human factors / psych perspective, recruiting for 1-bit likes / friendless / petition signature is much easier.

But critics, curmudgeon, creditors, and any number of others might point out that the ephemeral popularity contest of the graph of 1-bit edges is not a good representation of reality.

Presently the solution is "graph analytics" and trying retrospectively to bolt on additional info by inferring it from the graph rather than rich edges.

As a geek I love the idea of making our edges richer but as an investor I am skeptical it is something we'll ever see outside of carefully curated walled gardens / communities of devotees.

I'm surprised the HP touchpad charger got such high regards. I admit, it seemed to do well with non Apple devices, though it would make an annoying high pitch noise when idling.
"I hope that in the future there will be laws that will limit the monopoly of the device manufacturers and require complete documentation for the products they release to the public."

Oh god, please no.

On another note though, I'm a big fan of the work done by Clifford in bringing up a full working synthesis toolchain for iCE40; and I'd love for Lattice to cooperate and, dare say, fund the work.

I would program big FPGAs if I could do it with a free toolchain. Current toolchains are really cumbersome, and assume far too much about the designer's workflow. On top of that, they're absolutely insane to set up and activate. I bought a Zybo a few months ago to try their tools out, but after activating the seat I still wasn't allowed to synthesize to my device and basically just gave up. Lattice can take credit for theirs being the least painful; but it's still not what it could be if it were modular and free.

It's also not 9^9^9. If you are allowing use of exponentation, well there are an infinite number of other math symbols out there you can use too. BusyBeaver(9^9^9), or BusyBeaver(BusyBeaver(9^9^9)), etc.

And yes that's pointless know it all pedantry, but so is this whole post. The teacher obviously meant the largest number that can be stated without external math functions, and 999 is that.
China has a $777B problem with unpaid bills
I suspect your down-voters are thinking "are you sure about that?" Maybe they have smart phones and other gadgets which are highly advanced, but they might be living in a smaller place and less able to afford other things. I'm not even stating this myself, although it might be true... I just haven't researched it. But it's a thought that occurred to me.
Where's the ethical concern here? Familial relationships can be explicitly provided as can occupation. If it's all self-reported data then what's the problem?

The problem with the emotion manipulation study was that they were effecting people's psychology, not just click behavior. Which is creepy, especially because it apparently worked.
Apple's bill was probably under $80 million. It was ~$60 million through judgment at the end of 2013: http://www.reuters.com/article/us-apple-samsung-fees-idUSBRE.... The subsequent appellate proceedings would be small in comparison.

The bigger problem (for a large company) is the uncertainty caused by litigation. It's a distraction to the core business and can tie-up attempts to improve or expand on features accused in the litigation, not to mention it can spook investors.
Right, I was just pointing out that there's more logic in the game than that, so it's not that you can play Sokoban or nothing, but rather you can even cheat if you know how to get more boulders and you can break some too.

And as to the points about Medusa above... well. Of all the things that might kill you in one turn, that one will only get you if you're just plain not paying attention (to be fair, this is a very common cause of death).

I mean, you walk past a statue of Perseus (among many others)... which happens to hold one of several items that would save you, leading to the question of how he got petrified to begin with, but still.

Hmm, interesting... there's a massive number of statues, a palace layout that suggest some kind of boss, and, oh, Perseus with a silver shield and a blindfold. There might just be a hint or two in all that... :)

If there's anything that I feel is a real spoiler-only bit, it's the necessity of magic cancellation and which things give it. This is not well-described in game, at least in the versions I've played. (I think they did an update a while ago and I haven't really played it lately.)
After the third official adapter cord destroyed itself, I've taken to repairing them with heat-shrink tubing as well. The tricky part is that unless you want to cut and resolder the cord, you need to get heat-shrink tubing that's large enough to fit over the end connector.

I've found that 3/8" heat shrink fits over the connector, but 1/4" does not. But the 3/8" (at least for the brand I got) does not constrict down enough to fit tightly on the think cable. So I bulk up the cable with 1/4" silicone aquarium air pump tubing.

Instructions: Cut one ~4" piece of silicone tubing, slit lengthwise, and put just below the connector. Cut another ~4" piece of silicone tubing, slit lengthwise, put over the first piece of tubing with the slit on the opposite side. Put this second piece slightly higher, so "top" of tubing covers the base of the connector, and the "bottom" of tubing is ~1/4" shy of the inner layer.

Then cut a piece of 3/8" heat shrink to ~4.5" long. Slide the heat shrink over the connector on to the two layers of silicone tubing, so the "top" is tight to the L of the connector, and the "bottom" extends just past the farther (inner) tubing. Then shrink the tubing with some appropriate heat source (or carefully shrink with an inappropriate source like a match or lighter).
How to rip 2D DVD to anaglyph 3D
> According to the 2009 financial statement, about 50% of NPR revenues come from the fees it charges member stations for programming and distribution charges. Typically, NPR member stations receive funds through on-air pledge drives, corporate underwriting, state and local governments, educational institutions, and the federally funded Corporation for Public Broadcasting (CPB). In 2009, member stations derived 6% of their revenue from federal, state and local government funding, 10% of their revenue from CPB grants, and 14% of their revenue from universities. While NPR does not receive any direct federal funding, it does receive a small number of competitive grants from CPB and federal agencies like the Department of Education and the Department of Commerce. This funding amounts to approximately 2% of NPR's overall revenues.

So, still a small (10%ish) portion of their budget even if you count the government/CPB-derived portion of the revenue from member stations.

If a small amount of federal funding meant they had to make everything public domain, they'd probably just give up that funding and make some cuts. No one wins there, IMO.

"No two games will ever be the same."

Does anybody know how big the seed is for Diablo's RNG? I'm guessing it would have to be 1 value for the environment (to ensure saving/reloading into the same world) but would that 1 value determine all pseudo-randomness (AI aside) in the game (e.g. item drops and their stats).
Both Cayley and TitanDB aren't native graph databases. In fact, Cayley supports many storage engines, including MongoDB etc. This is because both are graph layers, and the data maintenance is done via the real database underneath. This has benefits in the sense that it's easier to build, but also doesn't perform as well when it comes to query latency.

DGraph, OTOH, is a native graph database. We do use RocksDB, but the data distribution and maintenance is done by us. It's optimized for decreasing the number of network calls, to keep them linear to the complexity of the query, not the number of results. This is of incredible value when you're running real time queries, serving results directly to end user. The query latency hence, isn't too affected by high fan out of intermediate results and should remain low; while providing high throughput.

In fact, the entire HN traffic is being served by one GCE n1-standard-4 instance right now, using all 4 cores really well :-).
For the benefit of those who haven't tried to read Piketty, I highly encourage you to do so. I don't agree with all his proposed causes or solutions, but the data is very interesting. And I didn't find him unreadable at all, in fact highly enjoyable, if you're the kind of person who likes to read serious non-fiction.
Re Wikidata, it's worth noting that they discarded TitanDB because it was assumed dead after the Datastax acquisition of Aurelius, which turned out not to be the case after all.

Also, the choice of BlazeGraph whiffed of politics. Wikidata (or at least one of the primary developers) seems to have been courted by the BlazeGraph people, to the point where Wikidata prematurely abandoned their research spreadsheet. This was at a time when there was hardly any public info/documentation about BlazeGraph, and its pedigree seemed completely unknown/untested.

> It's strange that on every podcast episode they don't suggest a way for me to contribute.

On NPR one app, they do occasionally have a "donate now" opportunity and their pitch ends with "we're looking forward to connecting with you...". If you're not using that app, then you might be hearing content that NPR syndicates but if they raised money it wouldn't be for your local station.

You can tell NPR went to some pains to integrate local broadcasting in their app.

If NPR-one hassled you with every item, it would get old fast -- some of the news clips are just over a minute or two long.
