Are there any limitations on the licensing of my AI (didn't see anything on the front page rules)? I'm somewhat concerned this is just an cool way of outsourcing the AI development for one of their mobile games :D
[at the very least it seems like a smart investment for recruiting]

Otherwise the competition seems cool and Helsinki is a nice place. Will certainly think about participating. All members being from the same country is a strange constraint though. I was actually looking forward to using this as an opportunity to co-develop with some US-based friends (I get why it's done though but I think allowing multi-country teams and having them participate as the country of the majority of the team members could have worked).

Edit: The screen shot makes me think it'll be a 3d game but since one of the company behind this is in mobile games it could be 2d (micro machines style). That's one point that should be clarified. Some more info would be helpful as well i.e. how is the world represented, what can we control etc.
KNN is not nearly as good as deeper probabilistic models. For example, if movie description mentions different subjects like "comedy" and "family", the model would not be able to differentiate them. It would only have a cluster "family comedies", but it won't be able to tell that a person likes "comedies".

I've recently done a similar research on finding "company peers" using company descriptions. The descriptions are put through the LDA (http://en.wikipedia.org/wiki/Latent_Dirichlet_allocation) to find the topics expressed in each description. Then, similar companies are identified using K-L divergence (http://en.wikipedia.org/wiki/Kullback%E2%80%93Leibler_diverg...) between their topic distributions. It worked much better than cosine similarity in my tests.

My guess is that it would work better for movies too. If interested, have a look at my results here: http://akuz.me/2014/03/finding-company-peers-using-lda/

You also have to look at the motivations. As an investor his primary goal is determining what is a lie and what isn't so that he can correctly value a prospect. As an entrepreneur it's not necessarily the main key to success, at least not higher than keep trying. This doesn't mean I'm saying lie by any means, just that you should always look at the source of motivation from the one giving the advice and how it applies to you.
That depends on whether the additional salary was being saved or spent.

To my knowledge VS caches the MSBuild projects (.targets etc) while it's running. So it's possible that, even if VS and MSBuild have the same degree of parallelism, not having to parse the MSBuild XML gives VS an edge.
This is called (spacial) arbitrage and this strategy has been around for a long time, well before HFT.
And with the limits not only of ontologies, but of models in general.

All models are wrong. Some are useful. As you pointed out, there is no such thing as a species in the real world -- it's just in the model that there's a species.

The model has been so successful that, unfortunately, it's treated as "true" by many people, which means that 1) they don't understand its limitations, and 2) they don't work to improve it.

+1, I'm glad you mentioned this.
But now you can't assume that Birds can Fly. You have to catch InvalidOperationException on every invocation. And what's special about Fly? What above other Bird methods, surely the same can be done to all of them? Now you can't assume anything about a Bird. So what good is the Bird abstraction then, if you can't make any assumptions about it?

This is breaking the Liskov Substitution Principle[1]. By saying that Penguin is a subclass of Bird, you're implying that I should be able to stick a Penguin into any code that expects a Bird, that code will just work, without it having to care about the particularity of that Bird actually being a Penguin.

> The point of patents is not to protect things that are obvious in hindsight.

You might like that to be the case but most of the canonical examples of things that should be patented are just that sort of thing. For example various patents have been granted for paper clips[0]. If it still isn't obvious how it is done after people see it you could argue that the patent isn't necessary - trade secret would do.

How much cheaper? We already have a small problem with Russian being the only way to get US astronauts into space. The privatization of space has been discussed for decades. Spending money on private companies is the logical choice. Jeff Bezos also got a small amount of Nasa funding. I would imagine that his company will also get future contracts.

Sorry if you don't agree with the decision but at this point we're just debating politics.

If those are property, then the same is true for an alcohol license and government contracts.

So you end up defining that anything exclusive granted by government is an property with inalienable rights and "owners", making both the word "property" and "rights" meaningless.

"One way HFTs do this is to place thousands of tiny orders while trying to detect the presence of a large trade being put through (known as a 'whale'). They use pattern recognition software to detect a large, price-insensitive seller or buyer and bid up (or down) accordingly."

A) On every exchange that I know of, the only way that using tiny orders gives you any information advantage is that on certain exchanges fill information is processed faster than market updates. Nothing in that fill information would allow you to determine if there is a large price insensitive market participant in the market vs lots of small price sensitive participants.

B) Nearly every exchange out there allows large participants a variety of mechanisms to hide their order flow. The simplest is iceberg orders.

C) It is a feature, not a bug that prices change in the face of large order flow. Every market in the world, electronic or otherwise works on this basic assumption.

Finally, your example about spamming quotes to create congestion on matching engines is a problem that has already been resolved. The exchanges themselves had a very high incentive to fix this. Their solution was to introduce fill ratios and to fine folks aggressively for violating them. I don't know of any main line exchanges where quote spamming can provide a legitimate latency advantage still.
So, semantics and rhetoric aside, what is _really_ this thing called "intellectual property"? In the real world, in actuality.

A big game of Who Has The Best Lawyers.

Nothing less, nothing more. An expensive game, normally better played by big corporations, sometimes by small optimized "companies" (trolls), completely uncorrelated with any notion of fairness or economic sense. Another thing that exists not necessarily because is a good idea, but because of enormous inertia, like many other things we do "because that's how things are", even if they are completely stupid. A legal meme.

(As an aside, I'm personally totally OK with trade secrets; I'd accept a sane, limited version of copyright as useful; and I think patents should be abolished. All of them. Software patents are just the most aggressive and vicious strain)
It seems to me that the best way to abolish patents is over time.

We are currently granting 20 year patents. Next year we grant 19-year patents, etc, etc. Past (and current) investors can capitalize on their 'investments', and the USPO and related services (attorneys) have a chance to scale down gradually.

Over time there would be diminishing returns on filing a patent, and players entering the world of software patents are faced with exactly the same world that they now face, except over time things look better.
Here's a podcast interview of the Gooseberry director: http://www.blenderguru.com/podcast-interview-with-gooseberry...
If the problem is sending money to your friends electronically (otherwise I'm nto sure how Bitcoin solves the problem of remembering debts or splitting bills), this is a solved problem for some people.

My credit union lets my transfer money to any other member of the credit union instantly with no fees. As it happens, nearly all my friends are members of this credit union (it's local and offers a much better deal than the banks) - and they have a mobile app so you can do it from your phone.

They've just added a general ACH function to it, to transfer to any account, but I haven't used it so I don't know if there are any associated fees. It doesn't mention any, but I associate the word ACH with some kind of fee.

So to me, this isn't a "find a new currency and financial system" problem, it's a "find a better bank" problem.
Just as an experiment to see how addicted I was, I stopped drinking coffee for the past week - was a huge awakening on how dependent I was (both physically and socially). Some reflections:

- I probably could not do this if I had to go into an office

- Headaches went away after day 4

- After day 4 I felt generally sharper/more motivated

- I feel much better after workouts

I highly recommend the exercise to others, good way to explore your limitations.

Interesting to see the evolution from the original game loop to the final system, kind of reminded me of these drawings "from ape to modern homo sapiens". One thing that bothers me with the final result, though, is that you end with a system where you can't tell the difference between two kinds of entities. If in your system infantry can climb aboard a spaceship but not the reverse, you can't guarantee that statically, unless you have a separate layer for this kind of logic.
Subjectively Nightly is close to Chrome fast in terms of UI and page first render. Other loads like maps.google.com don't seem to improve. But anyway that seems like an important step.

Wow - I read the article this morning, shortly before I had to present to managers on the current status of a project. Thought I'd try putting it into practice. The results: (a) I'm quite shocked at the number of (to be fair, very little) lies I would normally tell in such a situation, (b) It was weirdly relaxing being able to just sit there and tell the truth, (c) I've never received such good feedback from a presentation!

Litecoin Development Team’s official position on Litecoin’s proof of work
Was about to apply but I'm confused about the rules requiring all members to be the same nationality.

I have a French passport, so my nationality would legally be French, but I live in the UK, and work with English, Polish, Hungarian, Romanian developers(all living and working in the UK), some of whom I was considering asking to join a team with me. I think this rule needs some amendment.

Edit: also to explain some more, my French passport is a consequence of some awkward laws - I was born in the UK and have lived here all my life and can't even speak the language of my legal nationality. If I happened to win I wouldn't like to be a representative of "France" and I really dislike this "Passport must match" for the team - it makes no sense.
Offering equity as well as gadgets is an interesting spin on the co-op model. It works well enough; generally it's chosen for something that doesn't want explosive growth but instead is serving a community -- and that might not gel with the "get rich" urges of some startup types.
> maybe shouldn't be so fast in throwing it away because it doesn't match something

I think this touches on a big difference between science and software. In science, models are not "thrown away" because there is no need to throw them away. Multiple models can exist side-by-side, whereas it seems to me that this is not the case in software.

For example, Newtonian mechanics were great for a really long time. Then relativity came along and was found to be superior to Newtonian mechanics in some situations. Does that mean that we threw out Newtonian mechanics? No! It's still a useful model, regardless of the fact that it's wrong in some cases.

The point I'm making is that biology uses "single inheritance" not because it's right, but because it's useful in some cases. In other cases, where it breaks down, you will be forced to use a different model.

You'd define a climbing behaviour by a component on the entity.

So your spaceship might have a 'Climeable' component on it and your infantry might have a 'Climber' component. So only a 'Climber' could go onto a 'Climeable' , but not the reverse.
Recent F1 championships have been extremely competitive, with several teams in the running for the title. Red Bull have been dominant, but that's not solely down to budget - they have for several years run an almost perfect campaign, down to the last detail. The best driver can't win the world championship without the best team director and the best technical director. Red Bull's success owes as much to Adrian Newey and Christian Horner as it does to Sebastian Vettel. Brawn GP won the 2009 championships without a title sponsor, largely due to the inspired work of Ross Brawn in developing the double diffuser concept.

The F1 rulebook is a complex political compromise that needs to satisfy several parties with competing interests. Bernie wants the most profitable show, the FIA want a sport that best reflects the pinnacle of motorsport and the teams want whatever they think will serve to their advantage. That balance of power is fragile and constantly shifting. The Strategy Group and the Commission have agreed to a budget cap for 2015, which should put most of the grid on equal financial terms.

There is no simple answer to the management of Formula 1, nor any magic bullet to 'fix' the perceived failings of the sport. For every fan that just wants to see a fair fight between the drivers, there is another who wants to see a pure technical competition. For every fan who wants more overtaking and a better show, there is another that hates the contrivances of DRS, tiny rear wings and the dreaded Pirelli tyres. F1 is a sport that reflects all of the complexities and tensions of finance and politics, for better and for worse. It is the biggest, brashest, richest, maddest show on earth, for better and for worse. Try too hard to constrain those forces and you end up with something like A1GP - a sport that in theory panders to the fans, but in doing so loses the magic that makes people care about this gloriously absurd waste of resources that we call motorsport.
8th April – Open Season On XP Users? Defence Is Your Only Option Now
"They are able to identify your desire to buy shares in Microsoft and buy them in front of you and sell them back to you at a higher price," Lewis, whose book is available on Monday, said on the television program "60 Minutes" on Sunday.

I'm guessing the net effect of this is that you get trades for a few cents more than they would cost you otherwise. I guess "otherwise" means a perfect world where Goldman Sachs is a charitable organization run by Mother Teresa directing a band of angels.

This might be an issue for day-traders but if you're a buy and hold investor aiming for doubling or tripling of your holdings over years-decades, this small fractional cost at inception is likely negligible. (Which is not to say that the stock market is a safe place to be - there are many other cons to be aware of if you're a buy and hold person - insider trading, bad quality earnings, etc.).

It was not that long ago that investors were stuck with paying high commissions equivalent to several percentage points to acquire a stock. Now you can get 1000 shares of anything for $5. And maybe a few dollars more to line the pockets of HFT firms. Things seem better to me now on the whole.
