My Multiagent Systems class at UT Austin (taught by Peter Stone) discussed the Kiva system, along with many, many other topics pertaining to AI today.

A couple of videos about Kiva: http://www.raffaello.name/KivaSystems.html

A paper on Kiva: http://www.raffaello.name/Assets/Publications/CoordinatingHu...

http://www.cs.utexas.edu/~pstone/Courses/344Mfall10/assignme... has all of the readings for the class (with more on the 'resources' page). If you want to learn something about AI, it's certainly a good place to start!

If you're more into the algorithms side of AI, you should certainly read AI: A Modern Approach (http://www.amazon.com/Artificial-Intelligence-Modern-Approac...). It's a text book, don't get me wrong, but it clearly explains many relevant algorithms in AI today with accompanying pseudocode and theory. If you've got a CS background, it's a great reference/learning tool. I bought mine for a class, and won't be returning it!
It's an excellent lesson in just how thoroughly you can be defeated by your own preconceived notions.
That's what i'm working on...
A fun flip side is that you have companies like Vizio who are making a killing in commoditized electronics who outsource virtually everything and still have less then 200 employees (About 1/3 are support).

What's the problem? He has a right not to publish. This article screams "written because I'm mad at Wired." Get your own source and then we'll talk about who's a "journalistic disgrace."
What's the current state of teacup? Working with the current web technologies, I'd miss the library support that Python/Perl/Ruby have, and building everything yourself and packaging that as a starkit is nice for desktop apps, but for servers…
Homo Erectus (1.9MM - 0.1MM yeas ago) probably controlled fire (perhaps they can not make a new fire, but they probably can keep it burning). I am not sure if there is any evidence that they cooked with it, but when you have a fireplace for one million year ... more info: http://en.wikipedia.org/wiki/Homo_erectus#Sociality )

And Homo Neanderthalensis probably can have invited you to a barbeque :) .
"The "ancient" archery this guy idolizes never existed."

In the video, he says he picked up his ideas from old manuscripts and so forth that show such archery techniques in action (arrow on the right side of the bow, arrows carried in the shooting hand, etc.) and quotes one source (Babylonian? Can't remember) saying these archers had to be able to loose three arrows in 1.5 seconds.

Also, he makes a case for close-quarters combat. I think possibly he's studied this stuff more than you have? His basic claim is that he's re-discovering forgotten techniques so it makes sense your mainstream knowledge of archery wouldn't cover these things.
Thanks for the reply Brent, a few points I should clarify.

> Luckily they were able to get the Microsoft SQL team engaged to get them through this.

Looking at this statement now, I see that it might have appeared that Microsoft 'came to the Stack team's rescue.' My impression was that over time Microsoft alleviated some of the workarounds the SO team was running into.

> I'm not sure many teams would pursue this architecture if they knew the effort (and luck) involved.

I was simply stating that the SO architectural graphic looks deceptively simple and I can only imagine the amount of drama on hardware alone the team went through to achieve their goals. I do believe there are other OSS-based architectures (with likely more layers) that would require less 'workaround' effort to deliver reasonable performance/reliability, but compounded with SO's likely SLA & perf requirements on a closed-source RDBMS? It wouldn't surprise me to see some go 'good enough' and move on. I doubt anything is Ron Popeil easy when your trying to shed milliseconds on a persistence layer.

Hope this clears things up a bit.
It's not rude at all to catch their eye, or are you using the finger clicking method?
Don't try introducing two new technologies at one time. You pretty much have to use configuration management regardless if you're on Docker or not, so I would absolutely recommend to start with Ansible (or Salt/Puppet/Chef) and use that to its fullest potentinal. Only then do you know what your use case for containers are, and how to set them up effectively using your configuration management infrastructure.
It looks like the problem that gave me crackles when using the audio output jack may have been fixed with a firmware update. Thanks, you gave me reason to check and I might be able to put my Pi back into service!

Linus Torvalds (if I remember correctly) points out that there is no reason to optimize code beyond the point that the user cannot see the difference in performance.

It makes sense that if I click a button, and whatever that button is meant to do takes place apparently instantaneously, there is no point to making the code any faster.

However it is worthwhile to consider the effect of one's code on energy consumption as well as the performance of other parts of the system, generation of waste heat &c.
Looks great, I think I've found my new extra phone.

My backup travel phone is a dual-sim candybar, allowing me to leave my smartphone back at the hotel room while still taking my usual sim with me + a local sim of the country I'm visiting. This gives me a lot of freedom to really roam and still be reachable if I want to be, have some options if there's an emergency, to not really worry about my phone being lost or stolen, and not be tied to a power outlet.

My telephone company let's me have two sim cards which makes this really easy (whichever phone is turned on most recently is the active phone). I leave my spare phone in my car when I'm not traveling.
For a more extreme example of crime in this kind of very isolated place, I found what happened on Pitcairn island fascinating (and tragic). The criminals had to build their own prison to serve their sentences in, because the island didn't have one. Can't find the original piece I read, but e.g. http://www.independent.co.uk/news/world/australasia/evil-und... .
What would be nice is a phone like this with GPS and 3G/4G (with tethering). That way I could ditch my smartphone and use my tablet for actual browsing with the feature phone serving as a router only (whilst still being usable as a phone the rest of the time).

All the feature phones I've looked at don't have 3G/4G with tethering, which means they're unsuitable for my use case.
I'm not convinced. In 2004 when iChat AV came out, I was 22 years old and still in college...

I do agree about age and change.
I agree that the cost of writing books is high, which is why we have copyright. Your website is a poor example: you wrote something which was popular for maybe a few days/weeks. Your investment was (I assume) repaid over that time. To any viewer of your site, there is no cost to visiting you over visiting any other site, so there is no incentive to find/use an alternative source. I completely agree that, in such a scenario, being the first to market is a sufficient benefit, and that such content doesn't need much in the way of protection.

Now, are you simply just glossing over what I have told you about books and British authors? Do I have to point to you to an example of a public domain video game that actually made money? Since when my website stop being visible to the world after digg has made it through? I still get thousands of visitors each month.

such as eliminating software patents, would make the US system much more reasonable.

Do you have any sense of history whatsoever? When is at any point in history that the US patent system actually function the way it supposed to?

I can points to you horror stories about patents gone bad in the 19th century and the music sheet wars as well various submarine patents.

It's not some problem that suddenly pop up in some modern time that only impact the last 30 years or so. It's a problem that exists throughout economic history.
Instead of annoying everyone by arguing definitions for the rest of the day, let's just stipulate that we're talking about "crypto done by computers using products that you can actually buy and conceivably deploy in a commercial setting".

Unless you have a physically secure channel to distribute keys (in which case, why bother with OTPs), the fact that OTPs move the security model entirely to "key distribution" is an academic point. Any online key distribution system you'd come up with for your OTP is (a) going to become the fulcrum of your entire system, and (b) by nature of feeding an OTP, going to permit a far more restricted set of designs than any key distribution system for a "conventional" protocol.

The reality is, OTPs are entirely unsuitable for commercial information security. That's a strong claim, but not a slippery one, and I'm willing to back it up.

The arguments around OTPs are surprisingly isomorphic to the arguments around Javascript crypto.
Now that we know this is true it really puts Mike Moritz in a different light. He's always been considered one of the top VCs. This takes him way down the list as far as I'm concerned.
http://downforeveryoneorjustme.com/http://cb.vu/unixtoolbox.... is your friend.
I won't put quicktime on this machine, so I haven't seen the video. Do they mention the speed of the processor in the video? I'm suspicious of the actual processor speed since it wasn't mentioned in the coverage I saw of the event, and it's not mentioned here: http://www.apple.com/iphone/specs.html
Key features that will push the whole industry forward:

super high res screen (960x640)

front facing camera with open standards for video calling

high def video camera and 5 megapixel still camera.

It may be argued that some or all of these features were available on other phones, but Apple's massive weight in this industry will force other players to step up their game or fall behind. Who knew the Nexus One would lose its luster so quickly?

One thing still to be answered: Is the open standard around video calling really open? Or is it an embrace and extend standard that will be impossible for anyone else to get behind? If Android can / does adopt this standard, between the two of them they will finally put to bed voice calling (it's served us well for 100+ years, and good riddance) as the default within a couple decades.
i guess i was talking about VP8 on HTML-5, thanks for the detailed info ...
While it is morally objectionable, I can't help being impressed by what they (whoever 'they' is) seem to have pulled off. I guess this must be kind of what it's like when an opposing military leader pulls a really clever move on you.
They seem to be using the video-tag: http://dl.dropbox.com/u/4073000/html5.png

Don’t know what’s going on with QuickTime – maybe a fallback if your browser won’t play h.264? Does it work on Chrome without QuickTime?

(– edit: Three people [who downvoted me] seem to think that formulating a reasonable hypothesis and asking reasonable questions because of conflicting information is already too much Apple love. Or maybe they just think I’m lazy for not doing the research myself? Oh, well. Check out my other grandkid comment in this thread to see how testing my hypothesis worked out.)
How does Uber violate privacy? People are carrying their phones at all times, so THE BIG BROTHER knows where everyone is anyway.
I've been using Kotlin in the backend since 1.0 (4 years now??) and it's great, but it does have a few small annoyances. We still have most of our codebase in Java and routinely, we create new Java code instead of Kotlin for everything, interestingly enough (mostly because when a module is already written in Java, it's mostly a source of confusion to add a few Kotlin files - so we tend to only use Kotlin when creating new modules that are fully Kotlin). Also, some of our developers just don't seem to have enough abstraction power for the higher level of code you can write in Kotlin (specially when you start using things like Kotlin builders to make code "prettier", or just abust a little bit the "everything is an expression" feature to completely avoid separete statements - e.g. functions without braces).

People moving from Kotlin back to Java is not unheard of: https://blog.allegro.tech/2018/05/From-Java-to-Kotlin-and-Ba...
Guys, let's be honest. Python is DYING. Right here, right now.

And this is very sad for me, because in my opinion Python is one of the best scripting languages.
Unfortunately, Mr. Kitchen Hackers, Python has no optimization capabilities. GIL is great for calling C code, but it kills the language.

Just shut up and... save this thread. Sooner or later Python will die (Google is pt. 1 in this party). And then you'll shed a few tears and go program in Rust. Sad, but true.
Why does it matter that the little Italian restaurant run by the grandmother and her family has closed? We can just all just go to Olive Garden?
Maybe more emotional than it needs to be though. In real time the whale would have hours or even days to get out of the way.
You should be concerned about both. You don't have to pick a side.
That's a great point about the usual trade off between speed and security that exists for many applications. Subspace has innovated on some technology that enables us to move many security features 'in-line' while we're reducing the latency significantly. That's a good topic that I'll follow up on in more depth soon.

Security is a pretty broad topic, with many risk vectors involved. Subspace is building new versions of existing protections that no longer include the latency cost, as well as providing new tools to Security Teams at game publishers to help better secure and protect the experience of the community.

I'm curious what game security topics come to mind for the HN community.
Facebook would have to sell a lot of units, in a field with which they are mostly unfamiliar, and where they'd have very strong competitors in Apple and Facebook (and all the companies who invested in and sell Android, like Samsung).

I do not see Facebook playing catch up with Google, Samsung, the Chinese and Apple in OS, services (like maps) and hardware development, as it is too expensive to get FB into a competitive state in regards to tech, even if they forked AOSP instead of starting from scratch. A mere Facebook branded AOSP will not cut it (and then they'd still need to develop services on top, because people want more than just a facebook App, and app developers want more than just a generic AOSP + FB API)...

Then they'd have to solve the supply chain to get production rolling.

And then they would have to convince people to use their product, which is the toughest problem they'd have to overcome. Their reputation simply isn't great.

Any subsidies can only be limited. How much money could they reasonably offer a FB phone user (in exchange for their data) after having burned through billions in development, production development and marketing? Something like 50 bucks at most I'd think, if they want to still stay profitable. That's not yet a "convincer". Apple users do not mind paying a premium already, and in the Android world you already have lots of products at all prices. And let's not forget that phones (other than Apple phones) are relatively low margin.

Microsoft tried and failed to enter that market, already. And MS reputation with consumers compared to FB was a LOT better.

It's not impossible, but it would be a moonshot, and a moonshot that would be betting the company's well-being.

Entering the smartphone market is a lot harder than creating a new market like they try with Oculus, or Tesla did with electric cars[1]. And Zuckerberg isn't exactly an Elon Musk either[1] when it comes to public perception, or a Cook or Jobs or Brin or Page or even Bezos or still-at-MS Gates.

[1] The market was essentially non-existent and the few products that you could get were all rather subpar. Tesla essentially still had a first mover advantage, and supported their R&D with a limited premium car production with high margins, convincing investors to throw money at them and massive debt.

[2] Tho I have heard Zuckerberg described as a Martian, something that Musk aspired to be :P
Sounds like YCombinator to me.
Denmark, in the 1960s. Elementary school grade 1 to 7, no kindergarten.
I wouldn't be surprised if chronic inhalation of natural lemon or pine scent were unhealthy too. Limonene can cause skin irritation for example. Plants generally evolved essential oils to avoid being eaten, it kind of makes sense that inhaling them might be unhealthy.
For some reason, the gods of HN don’t want this topic to reach front page. Yes, it’s political, yes, it’s divisive, but judging by the original thread it seems like there is interest for this topic in this community.
Latest EmDrive tests at Dresden University shows it does not develop any thrust (grenzwissenschaft-aktuell.de)

If you want a new stylish TV, i can recommend Samsung "The Frame". It is a 4K TV which you can hang on the wall and it looks like a painting.

Note that you absolutely must not connect it to the internet nor accept any agreements or policies. It then becomes a "dumb" TV which displays art when turned off.

Then connect Apple TV to make use of it.
Does that let you spoof sender address on any phone? I was under the impression that you had to create an account with a SIP provide to do that.

(Btw a Google search for "Hushsms" results in shady/cancerous app stores that all seem to mirror each other. Where is the official website/thread?)
The "real names" myth was the biggest scam played against people in the past 15 years. The media are also wholesale responsible for perpetuating that damaging trend. Historians of the future will look at the past 2 decades with disbelief.

Except not everyone has the same type of happiness. This is why the declaration of independence does not say "life, liberty, and happiness", it says "life, liberty, and _the_ _pursuit_ _of_ happiness". There's an implied statement there that not everyone, or even most will be happy, but we should be free to be able to seek what makes us happy. You don't have a right to happiness, but you have a right to be able to try to make yourself happy.
Hmm, good point.

I've only really been following things when shit hit the fan today. It took multiple dozens of minutes after the Capital was breached before the National Guard was called in, which is still too long in my opinion.
Cloudflare + App Engine is working well for my mostly static site. The combination is completely free for any amount of traffic, and scales practically to infinity with literally zero effort.
I think their point is more competition is better regardless; every one of them will try to find some way to make themselves seem better than the other. Though the problem with that regardless is that from a business perspective, there's a very finite amount of spectrum, and it's being gobbled up exclusively by four (maybe soon to be three with the pending Sprint merger) companies.

From a technical perspective, there's definitely been mixed reactions to the effectiveness of 5G technology. That's another topic in and of itself, though.
I think this article is a bit misleading. The placenta did not evolve from an ancient virus. A protein found in primate placentas (but, interestingly, not found in other placental mammals) is clearly related to endogenous retrovirus proteins. (I do not think that HERV and HIV have much to do with each other -- they are very different viruses). But it is pretty interesting that primates started using this protein relatively late in mammalian evolution.
Education has changed. Our educational institutions used to be a bastion of free speech where tolerance for disagreement was treasured. This is not the case today, where merely speaking disagreement to the majority narrative gets your professorship cancelled and gets students disciplined.
That guy is almost certainly police, seeing as he's shouting at the people to leave the building: https://i.imgur.com/teOuPwU.png

An educated populace is also the most dangerous thing to anyone in power (politicians, business operators, etc.). Even without being a coordinated conspiracy, that is a constant force working against improved education.
Have any links handy?
Or they think they will be pardoned because why not? Trump already pardoned literal war criminals.
If it works, it works. There will be no observable performance difference for DDR4 SDRAM implementations with the same timing parameters, regardless of the trace length. There are systems out there with 15cm of traces between the memory controller pins and the DRAM chips. The only thing you can say against them is they might consume more power driving that trace. But you wouldn't say they are meaningfully slower.
IIRC in terms of patent fees: China is massive net importer: $6 in patent fees for every $1 they receive, US is opposite, massive net exporter. Hence Chinese drive to build / buy domestic patent portfolio and slowly implementing IP standards until they can play the same crooked IP extraction game.
> But in all 4 cases, it clearly and significantly shows that people with low actual ability overrate themselves and people with high actual ability underrate themselves.

I read the data quite differently. I read that people don't use the full scale when rating themselves. The self rating scale goes from 60 to 90. If you correct for that, people kind of seem to do a nice job in self evaluation.

It can be explained, too. People have social pressure not to rate themselves near 100%, nor in the bottom half of the scale.
Here in the Netherlands, crime statistics are declining, but many people suspect that the real reason is that the police often refuses to register declarations (or advises against filing declarations).
RTFM is never a valid response. At the very least you point the user to the specific section of the manual.

It's this philosophy that made the ubuntu support forums the most agreeable (and pretty much most popular), at least for a while. You can RTFM people, but then you show that you hate your users, and they will leave.

Not only the people asking, but also others reading it. Like this example shows very well. This bad comment not only made d0ugal search for a different project, but also made sure I won't use it, and worsened my opinion of the author considerably.
> The author is also quite spiteful about it

Sadly this is more or less the norm and in my eyes the source of the large disconnect between people who believe in things like "linux desktop is for everyone" and actual average users. Nobody wants to read a long principled rant when they're looking to actually use their computer.
