An *Einsteinian* thought-experiment in Deep Q learning and Causal embedding
Enter the fictitious witty preschooler:

If the preschooler pays attention in deep q learning class, he/she may observe that these learners don't typically use 'pooling'.
If said preschooler likewise observes state of the art in causal physics learning, (ie the Yann-Lecun-introduced "uetorch") he/she sees that it uses 'pooling'.

If the preschooler isn't too distracted by the passing kitty, he/she will soon recognize that these things appear to be opposites at first glance; pooling vs non pooling frameworks, though it may be sensible to combine these, because:

1) Humans learn by reinforcement (dopamine signals encode error)

2) It appears that humans have some in-built intuition for causal laws of physics at childhood (ie: mama I can probably predict with high accuracy, where that tower block will fall), particularly as new abstractions develop in the brain as child matures.
The following abstract produces logical lemma, in deep learning terms, for integrating the temporal difference regime (reinforcement learning) WITH pooling/non pooling architectures.

> Bonus round: Is it worth it to spend $100 just to travel for an interview?

As someone else mentioned, there is your red flag. If a company can't put up a good face for the interview and compensate your for your time to travel there, that is a good sign they'll be stingy with bonuses, benefits or other things in the future.

I was impressed by one company I interviewed with, there were prepared to pay me for gas for visiting them because I drove there. Other company which flew me over, gave me an extra $50 for the cab on the way back and for getting a dinner at the airport when I flew back. It is a small, relatively cheap token of appreciation that makes a good first impression.

My advice is don't ask explicitly as the first thing about it, but as they invite you, when picking a time, ask the person making arrangements, what company will compensate you for amongst other questions. This should probably not be the deciding factor and if you really like the company otherwise, still go, but it is just another heuristic to use.

Other red flag -- they give a very small decision window. They don't want you to have time to get more offers in and compare. In that case, ask to midify the date to think longer. That is a good test how agreeable they are. If they don't want to, that is another red flag.

One one hand I agree with you. On the other hand, looking at how far movie/tv FX has come, like http://nerdist.com/amazing-game-of-thrones-battle-of-the-bas... - I'm not so sure.

10 years ago, the state of the art was something like Nvidia 8800 gtx - it looks like the recently launched 1080 is a handwavy 4-10x in terms of performance[b]. ~10x the RAM, but not bandwidth etc. Having recently(ish) upgraded from early 2000s system to an i7 with an AMD R9 -- I would anecdotally claim that we've come quite a long ways in ~10 years. Even if part of that is "just" making 2k-4k gaming a reality.

I think it is a little bit like optimization of performance. Small changes in aliasing, changes in resolution, refresh rate -- they all add up to move us closer to "the real". And I think one shouldn't ignore the work done on the modelling, skeleton, animation and physics side either. It all helps make artificial worlds feel "more real".

With all that, I don't really see why "realistic" is such an interesting goal. For simulation (be that virtual tourism, or a driving simulator helping people become better real world drivers) - sure. The tourist want beautiful scenery, the driver wants real physics (and neither would mind getting both).

But for gaming -- chess isn't very realistic, go is rather abstract and tabletop roleplaying games have the best graphics engine - shared with literature - the human imagination.

Probably not true. Are we to assume that the English/German navy was composed primarily of homosexuals? And can this difference be attributed to the comparatively longer voyages made by English sailors?
Clash Royale is their new game of the moment. It's taken away most of the meaningless grinding, leaving just enough to monetise.
> On the set up, it might be right but unfortunately I do not have a room to spare for a full room VR.

Are you using roomscale? It wasn't clear from your comparison. It's the biggest difference that matters between Vive and Oculus. Roomscale is fundamentally a superior experience. Until Oculus has a generally available implementation of it, Vive is at a different level above Oculus.
There's a big difference between working a weekend and partying for an evening. The latter is typically optional (and if its not, that's a problem).
Presumably you'd say the same things about other traditionally gendered inanimate objects in english such as countries or the moon?
Exactly this. There are also types of ships that are feminine gender in Russian (yacht, schooner, boat, submarine etc) and they follow the same gendering as in English. E.g the famous Putin's phrase "Она утонула" (She has drowned) is in reference of the submarine Kursk (a masculine gender proper name).
I think a lot of people want the Oculus to fail, because it's Valve vs Facebook. Valve is generally loved, Facebook is generally disliked. Had Palmer not sold to FB, I think they would have much stronger support and it would be a very different story. People were behind team Palmer+Carmack until they used the kickstarter dollars to "sell out." Oculus definitely didn't help their standing in the community once they started trying to buy exclusives and add DRM.

Kind of reminds me of the Makerbot fiasco. Like Makerbot, Oculus has lost much of the early adopter community, but if they can hang on long enough, they can capture the mainstream adoption wave and it might not matter.
Link is dead.
Game (world) design (and art in general) is about accommodating and working with the constraints of the medium. Make a realistic (or fantastic) desert game today, if you can't get the water right. Make a great simulator for the oculus (eg: Elite: Dangerous) rather than trying to make a roller-coaster simulator if your user won't be able to get multi-million-dollar 360-degree rotating simulation chairs (think NASA style stuff).

As for a "VR" river, there's nothing wrong with filming a real river with a 360 degree camera, and then augment that scene, rather than "building a river". A real river on a virtual Mars, might look better than a virtual river on a virtual world.

Of course you can dream up a game that hard to bring to life exactly as you envision it using current technology. That doesn't mean new technology doesn't open up a few new possibilities. If you run into problems thinking big and complicated, try thinking smaller and simpler. I'm sure a Populus style game would be a lot of fun with the DK2 (isometric sandbox god simulator game with slightly cartoony graphics). Why does it have to be realistic?
The more that I think about this, the crazier it seems:

The argument seems to be that the cost of phone base stations is holding back development in 3rd world countries, but no evidence for this is offered.

Firstly, the world-wide mobile phone market is huge and fiercely competitive. You can now buy a 2G Chinese base station surprisingly cheaply.

Secondly, there are thousands of tons of secondhand gear lying idle. An example: Australia is about to rip out all of its 2G network. This will mean umpteen thousands of GSM/GPRS base stations being dumped for scrap.

Thirdly, the cost of the radio gear is a small part of the total cost of a base station. The cost of the Shed, Power Supply, Solar Panels and Batteries, Mast and footings, Coax, Diplexers, Antennas, etc, will be far more. Just the expense of running power to the top of the hill will likely exceed that of the electronics.

But the big cost will be extending a dozen or so outside lines to the national telephone network. Just setting up the billing arrangements, etc, will be a huge job.

The bit that really worries me would be staffing. I can imaging a bunch of enthusiastic western hobbyists turning up to install the gear, then departing leaving no-one to maintain it. I'm betting that after a week or three the whole system will be down.

But lastly is the assumption that the locals can't do all this. In any remote community there will be skilled local entrepreneurs who are selling and repairing electronic equipment. It is these people who need to be the ones who install a phone system. If they haven't yet, it will not be because of lack of cheap gear, but because of the non-existence of basic infrastructure, eg a national phone network to connect to.

And you can be sure that if there is no local phone tower, there will already be a VHF mobile radio network used by police and businessmen (eg the "red radio" VHF CBs in remote Thailand).
This is a good overview of how hackers actually crack hashes if anyone is interested. https://www.trustedsec.com/june-2016/introduction-gpu-passwo...

The other things to take into account:

Code complexity, quality, and cost of ownership. Rolling your own scheme when mature and well tested code already exists is generally something to be avoided, especially when crypto is involved.

Force multipliers. Your server is probably using a CPU to calculate hashes, while hackers are using at least GPUs and possibly FPGAs or other hardware, which are hugely faster than your CPU. So yes, while you can use any cryptographic hash with enough rounds to make high quality passwords unlikely to be cracked, using a password specific algorithm correctly will greatly reduce the advantage hackers have. This makes more of your user's passwords unlikely to be cracked.
fb probably shut it down. It had footage of a shooting. Very sad and grim stuff.

Ha, Amazon's AWS fits. Didn't call on the agreed date for phone interview. Then when visiting on-site, future manager, probably the main person I should have been talking to, wasn't there. Quickly assembled together an interview schedule in 20 min with people who , except maybe two, seemed distracted and just wanted to go do something else. Forgot about me during lunch. So was left sitting in an office for an hour without anyone checking on me (eventually got up and started wondering the hallways hoping someone would stop me and ask me -- "Hey I don't think you belong here" and I was hoping to reply with a silly joke about trying to steal AWS's root CA private keys). Then of course they promised to call back with a decision in 2 days, which was more like 2 weeks. Didn't get an offer, no surprise (I did get snarky about the "leadership principles", they probably didn't appreciate that), but it did make a good story I like to tell every time interviews come up.

"Unlike X11, where the graphics primitives were rather low-level and all input event handling involved round-trips to the client, NeWS was advanced enough that simple widgets, such as scroll bars and sliders, could be implemented entirely server-side, only sending high-level state changes to the client, more along the lines of “slider value is now set to 15” than “mouse button 2 released”. Similarly, the client could ask the server to render a widget in a given state, rather than repeatedly transmitting sequences of graphics primitives."

I worked on a demo experience for the Vive unveiling and for the first time in my career I felt like VR was more than a gimmick. We were working with beta (maybe more like RC) hardware, had no controllers, and only one tracking cube.

I had two a-ha moments with it that sold me... There was a small demo room called something like Shopkeeper (think an old goblin's hut filled with wares) and I actually reached out to grab a faerie/wisp that was buzzing nearby. The second was a Valve demo app where a Portal like robot came stomping into the room and I actually jumped the F out of the way, only to have the floor start falling out from under me and scrambling back to safety.

For a few fleeting moments at a time there was no virtual, it was reality and it was freaking amazing. And all this without the added immersion the controllers provide.

The Vive is by far the best VR setup I've tried. It's made the rifts we had around seem like toys.

The mental model from economics that is widely misinterpreted is comparative advantage. Most think it means you/a country etc should specialize in that which you are best at. And then free trade will work to your advantage. But it actually means that even if you are worse at producing products A and B than another country, if your ratio of A/B is better than the other country, it would be good for you to produce A and trade it to the other country for B etc. I
This article made me think a little bit about games. What are they? Art, waste of time, intellectual gummies for your brain? All of the above?

However, I believe that there are forms of entertainment that can enrich your life and others that are simply entertainment. As long as you are aware of it, and being intentional about your decision there is nothing wrong with that.

I can definitely remember games that have enriches my life one way or another like the original Metal gear Solid, Silent Hill or Braid but I can also think of many counterexamples like Counter Strike... These games were polished as hell but they just put me into this zombie state where I just cared about one more frag, one more, one more... Without being aware.

What do you guys think?

We're doing something similar, but using mesos. We bundle tests up, so we don't have to eat the setup costs for every test, and try tracking test pollution by splitting bundles when they fail & running them separately, again.

Dear AnonymousUserWhoLikesToHideTheirName,

That's just hilarious. For as long as I'm saying things that conform with the majority's opinion, I will be upvoted. But when a have a different opinion, then I will be downvoted until I censor myself back into conformity. Is that how things work here, on Hacker News?

Have you by any chance heard of concepts like pluralism of opinions, freedom of expression and that sort of things? I'm not sure where you come from, but in some parts of the world people are freely able to have a civilized discussion around complex and sometimes controversial matters. You may consider going abroad, living there for a while and learning how a liberal society works. Will be a great help to you.

Hi Jeff, can't wait to buy a copy of everything you write for FreePascal and Lazarus.
My thoughts exactly. And then "and what's wrong with that?" But then I realized this was about a silly video game. Oh well.
Fair point -- I forgot about MOSIS. Agreed, pretty reasonable for small test runs. I guess I've mostly heard of tapeouts when proving out a full design though, e.g. TRIPS from UT-Austin (and they had a team of ~20 students, so that was worth a number of dissertations). I can't imagine doing a tapeout while working on caching or branch prediction or other core comparch subfields like that -- the deliverable is an algorithm and/or a new idea, not a physical proof of concept, and the usual effort (a grad-student-year or two, at most) isn't high enough.

(All that said, seeing a real chip at the end of a project must be a heck of an exhilarating feeling of success...)
Where to find good social media/marketing expert?

The oft repeated performance reason is that hardware RAID controllers have battery backed write cache, which really improves durable write performance; something traditional relational DBs do quite a lot of.

Also, these machines were built by DB people, who have traditionally placed a lot of value in hardware RAID controllers, and to be fair, the HP controllers worked well with HDDs. Also ZFS wasn't a realistic option for production Linux in 2013. Me personally, I'm not a fan of exotic proprietary hardware, I much prefer working with JBOD disk setups and software RAID where appropriate.

>Can I get funds from US angel investors and build my company in my home country?

That is entirely up to the angel in question. I do however suspect that many people would like the reassurance of being able to see you face to face occasionally. Handing a check to someone about to fly out of the country would understandably make a lot of people nervous.
For the sake of discovering a middle ground between our arguments, let's look at an example of a >$1B company running Rails: Github.

Most of Github's stack is Ruby on Rails, with specialized components/sub-systems written in C. This is a common theme amongst companies that use Rails or Python at scale.

There's a reason why people keep those languages around. Its the same reason why they tend to be used for MVPs: the tool gets out of your way so you can focus on solving the hard problems of your domain. The longer you can preserve those ergonomics, the better.

You seem to be familiar with Elixir. May I ask you some questions?

. What kind of web applications are you building with it? I'm asking what kind of web apps or scenarios do you think Elixir is particularly well suited for?

I saw a thread on Elixir a couple of days ago and it piqued my interest and I saw a couple of videos that were posted there, one from some Ruby Conf that claimed that Elixir was giving better results (in request time) than rails. He never explained how that was posible or what would have been the results if he would have been using a cache (it's always faster to hit an in memory cache than hitting a db that has to touch disks, so if he speeded things up without a cache he would speed things even more with a cache). Then I watched another videos from some conference in Oslo or something, and from what I could understand he was doing away with the db completely.

. So I have another question, how do you architect your application in Elixir to keep application state though multiple requests (sessions) on multiple boxes without using something like memcached or redis (or a network disk)?

. Even if it's running on only one Box? Where does data reside if you are not using a db?

I have a basic understanding of Erlang processes (what's explained here: http://stackoverflow.com/questions/2708033/technically-why-a...) and how it's particularly well suited for concurrency. My questions are about Web Apps and Elixir and scaling.
Somewhat related: Nintendo sold 770,000 units if their Virtual Boy in less than one year.

The Virtual Boy was nothing against the current VR products and for a Nintendo product a pretty mediocre one then, maybe their biggest product failure but they still did 770k units.

I have such mixed feelings about this style of monetisation.

On one hand, (as that talk that Blow gave a while back) it usually affects game design badly. If you remove the money element, of course you wouldn't have to sit around for days while things upgrade.

But on the other hand, the micropurchase model has helped to sustain games much beyond their original "Fresh by" date. The one that comes to mind for me the most is Team Fortress 2. A huge amount of content has been added, and is at this point subsidised by item purchases. Of course League of Legends and other DOTA-likes do this too.

And then there's Hearthstone, which keeps content fresh through constantly selling new expansions a la MTG.

Some might make the distinction between the good games and the bad ones, but I have a hard time imagining one without the other.

----

I think a bit of a weird aspect of this is that games are now incentivised to keep you entertained longer. If you buy a $50 game, it's fine for it to take 5 hours and for you to be done. There's no financial advantage for the game maker to keep you around longer.

I guess a lot of this is a distinction between kinds of games though. Some games are like books, others are like sports. Nobody complains about the addictive nature of soccer....

With full body tracking and depth cameras you could put 3d avatar bodies in.

Obviously the face would be obscured by the headset, but it's dark in a cinema and people are normally looking at the screen when watching TV at home. So it might actually end up being more social.

Even with just simple 3d positioning of the headset and input devices with a simple visual indicator is enough to get a sense of someone being present. Add a microphone and 3D spacial positioning of voices.

Of course the current generation of technology would make that hard and rare. Not too many people you know will buy a $1000 headset. Everyone would need to bring that and a fairly powerful computer to the one place.

Although physically being present in the same room isn't required.
