Why I Should Care If Polar Bears Die
Hong Kong is still a SAR.
AI is like rendering in that the programmers doing that tend to cluster together at conferences, so they aren't completely siloed. The subfields that don't have that clustering effect are the ones not established enough that it's become a known specialty. Where isolation tends to be more obvious is when looking between different sectors of gaming: people working on mobile F2P have a vastly different view from AAA console devs, and both are likewise different from indie PC devs.

But AI in games does have a bit of an identity issue at times in that the obvious application of game AI(an AI opponent) doesn't represent the broader picture(FSMs appearing in every character controller and interactive element, planners employed in some forms of procedural content generation). With machine learning being the hot thing now, some AI devs are looking for angles to use it, which tends to push them towards backend data work that isn't too far removed from what other web and mobile companies are doing.
Secrecy is pervasive in the game industry, and used to be much worse. In many cases it goes as far as lawsuits over things that would be relatively minor and not worth suing over in other industries - like the look and feel of speech bubbles in multiplayer games.

Things have gotten better over the last decade or so, with game studios letting developers publish research papers or slide decks or even entire software stacks as open source. Sometimes studios pay to send developers out to give talks and do recruiting. A decade ago, it would have been a hard sell to even get permission to buy your own ticket to a developer conference at most studios. The last AAA studio I worked for had similar policies - only a few people at the studio ever went to conferences, and we all had to pay out-of-pocket. That studio's policies have changed and they now let employees give talks. In comparison, the silicon valley firms I worked for had better wages and encouraged us to both attend and give talks. I think some of the improvements in games industry culture here have probably been triggered as a result of competition from SV startups and open source.

When it comes to AI there are specific challenges: It's very hard to repurpose one game's AI for solving another game's challenges. It's very difficult to build truly general AI frameworks. Good game AI depends on knowledge of game systems, content, and mechanics - how each ability works, how the environments are laid out, the structure of level objectives, etc. All of these things can end up changing during development, and in a multiplayer game they may vary from match to match. As a result, even if you have a bunch of knowledge from other titles and you can reuse source code from the best titles in the market, you may still fail to build good AI for your game on your first few tries. It's that difficult.

General purpose machine learning frameworks have helped here though, and people using off-the-shelf engines like Unreal can take advantage of all the existing tools there to start building AI quicker. So that's nice.
"Being long Tesla is making a bet that the future will look different."

This is funny to me. I think Tesla is selling more of the same: various big cars to car drivers who can't imagine a society without cars.

It feels like "trickle-down environmentalism", and I don't have a very high opinion about the economic variant.

A real radical vision of the future would be betting on train and bus companies or something wild like that.
yes, that's why Canada is just as bad a Mexico, with Canadian drug cartels mass beheading their rivals in the streets of Toronto.
Things change. The car will landscape will look pretty different in 20 years.
I've tried running newer CentOS and Fedora GNOME environments but they always feel so much slower than Xfce or unity. When I open ps it shows gnome-shell constantly using 10% cpu and 20-30% memory. Opening menus and switching desktops is such a pain with all the delay. I found this true with Virtual Machines as well.

This is all fine, but if it isn't inert and if it 'leaks' graphene, it can be super toxic as well. I don't want to pu-pu it, but it is legitimate concern.

Cuban: Uni Basic Income Is “One of the Worst Possible Responses” to Automation
Truth is not measured by the production of cognitive dissonance. "Cognitive dissonance" is not even a validated phenomena, it's just barely more than psychobabble.

Your comparison here is dangerously wrong.
in what way is Camp of the Saints an endorsement of genocide?
You should try living in Sinaloa, Sonora, Tamaulipas, etc..

The places you listed are all the safe states, which effectively is a different country.

It's not super complex, the states near the Gulf/Yucatan are generally the safe ones.
When you pay people $100million for the grand accomplishment of sweet-talking the CEO, you get... Google+.
Receiving a death threat is nowhere near as terrifying as seeing one of your colleagues show up in the obituaries.
I can understand that when Google was on a technology growth curve in 2007 that a single engineer could hit a home run. I think that is much much harder today. So I would have to see it. I'm not saying it's impossible but I'd have to see it.

My favorite Google engineer idea was how much autocorrect improved search results and efficiency. Awesome idea but I doubt it contributed $100M in revenue. MapReduce, good idea but I doubt it contributed $100M in revenue.

One engineer, $100M is easy to say. It's really hard to do.
Project Mohole
Fix is in the App Store! Update should come soon.
Another reason could be the push to competitive gameplay. Plenty of people would buy similar titles and never touch the campaign, making spending a lot of time on AI not worth the time.
Apple is very specific about their human interface experience, IMHO. Could be a case of Apple deciding for people the amount of lag that people want and being wrong.
DWM also adds at least one frame of latency (usually two I think?) at all times. If you bypass composition (through exclusive mode fullscreen) that additional compositor latency goes away. Higher refresh rate would also drop that latency, naturally.
You can also observe it in many cases while dragging a window - the composited window's position will lag behind the position of the cursor.
RE Haloe CE:

Especially on the Legendary difficulty. To this day, the Halo series has the best set pieces and is overall the best single player experience of any FPS save for Half-Life
I'd argue that combine soldiers were closer to objects as part of physics puzzles than intelligent opponents.
Honestly the author should try applying for renting an apartment/room in NYC. I had to give, ID, Letter from employer/university, payslips, SSN etc. Weeks before signing the lease, which actually ended up happening literally the day of move-in. The 250$ charge seems exorbitant, but ~50 to 100$ credit check fee is common, most agents will provide a realistic assessment of your chances.
As many drought hot spots around the Globe. I hope this gets the traction it really deserves
> I think there are a lot of pretty good reasons why the vehicle market is going to change significantly in the next 15 years

But not necessarily shrinking the market. The cost of mobility goes down, consumption will go up. How high? I'm going to guess absurdly high. The reason US cities are sprawling messes is that they were built as the cost of mobility dropped off a cliff (cars and trucks replaced horses). Go read Clifford Simak's "City". People will live in self driving cars and commute in their sleep. It's going to be nuts.
I doubt it. I'd bet both ceos are suggesting plans to be more powerful than the other (or simply to remain employed) and this is one of those power struggles.
Several continents have failed states: South America, Europe, Asia, and Africa.
For a AAA multiplayer-focused shooter, the incentives aren't there, because multiplayer. Single-player campaigns in that game are merely pretty tutorials for the "main event", as it were, so if they're going to invest money, its not going to be in AI. Single-player games are a different story though, I'd love to see less predictable AI in games like Mass Effect.
Imagine the effect HL3 would have on HTC Vive sales
Not sure if that's sufficient, but I wanted to answer to your "Americans..." comment:
This isn't just an issue for Americans, it's also bad for actually highly qualified foreigners and other companies. Because a few companies gobble up all the visas, the rest have to go through the lottery. Which actually makes it hard to hire highly qualified immigrants, because it takes agrees to see of you're lucky.

I've been through this, and it sucks. In the end I got another type of visa, but that cost a lot of energy and money.
League of Legends is a really good example of this. They've done a pretty good job of gimping their bots considering that simple player-made bots can be competitive at the highest levels of ranked play.
Not really. Basic thermodynamics tells you that if your only input is water with a certain salt concentration and your output is water with a lower salt concentration (plus either brine -- very salty water -- or dry salt), then there is a minimum free energy cost.

> Based on thermodynamic principles and practical kinetic requirements, the theoretical minimal energy for desalination with FO is always higher than that without FO. In other words, using FO cannot reduce the minimum energy of separation.

https://www.researchgate.net/profile/Shihong_Lin/publication...

The idea behind forward osmosis is to replace the salt in water with some other solute, like sugar. A strict 1-particle-to-1-particle replacement can (I think) have arbitrarily low free energy cost, but then you're just stuck with sugar water instead of salt water. In certain special cases this is fine (like for emergency water generation at sea, when you don't mind drinking sugar water). Insofar as low levels of sugar can't be tasted, and insofar as you have access to free sugar, you can avoid the energetic cost of removing some of the salt by replacing it with sugar. But I don't think this is very much before it becomes noticeable, and sugar isn't free.

If you happen to have excess thermal energy from some source, there are also ways to harvest some of this using forward osmosis, but this is really just another way to smuggle in free energy. In principle, you could use the heat gradient to generate electricity and then use that to power normal reverse osmosis, although which is more efficient will depend on the details of your equipment losses.

I could up vote your response a few more times if it was legal.
I literally wrote the same comment. Though I must say that the relatively cheaper rent on a year/multi-year lease vs enormously overpriced sublets/AirBnB makes it a worthwhile investment.
If I may say so, that is a much less noisy and more readable version of this list.
I do agree with the author about the lack of progress in FPS enemy AI.

I follow AI much more than I following gaming. I definitely find it curious that enemy AI has hasn't made a lot of progress when game-playing in a different form is such a focus of deep learning.
> the 3 companies provide a luxury campus for employees that are actually attractive.

Sort of. They still use open-plan offices (at least, to some degree; I can't know whether all 3 use them for all teams in all locations). All the free gourmet food and trendy furniture in the world can't increase productivity enough to make up for the effects of large open-plan offices.
I'm getting real damn sick and tired of "what the big print gives, the spidery print takes away" and how we're all just supposed to be OK with this, as if this is how the world works or some crap.

So reject it already. Use cash. Spend only money you already have. Keep it simple; don't accept anything that comes with fine print. It's really not hard, you're just not used to saying "no" to it.

The world, as you function in it, is OK with how this works. Nobody is forcing you to comply.
THE PRIDE AS OBEDIENT CHILDREN IN OUR GENERATION
Saving the credit card charge isn't a win. Turns out that operating cash-on-delivery has significant overhead due to the cost of handling the cash, accounting for it etc. More than that, returns are much higher when the customer hasn't paid for anything. As a result, almost all ecommerce sites in India incentivise you in one way or another to pay online. I know one that will give you $0.5 off if you pay online, which is approximately what COD would cost them.
Consider that perhaps you do not represent the average student at that school.

> Let people know what they're getting into.

Let's say an honest lending start-up rushes to fill this niche and then rejects people's applications based on imperfect academic record, lack of summer jobs or internships (so potential laziness), subpar math skills and very minimal knowledge of foreign languages (so indicative of poor information retention). It also honestly tells you that art history majors have no place in a business world, and honestly maybe a career in plumbing is a better fit.

This is just based on their model, and the rejection is worded in a nice, legally safe and sound, way.

How long before such lender is being sued into oblivion for discriminatory practices?
Yep, their human rights track record is terrible, but even with that, Dubai is still safer than most other large cities.
