> The tit-for-tat is very effective in the classical iterated prisoner's dilemma, but it is easily exploitable in the program equilibrium verion of the game. This is because the bot's decision is based entirely on the history of previous moves, so an opponent can always predict when the tit-for-tat bot will cooperate and then defect against it.

Unless I'm missing something, doing this naively doesn't let you exploit TitForTat, it just decreases your reward from (3 every round) to (5 every other round).

You can still exploit TitForTat, e.g. by defecting in the final round. But that's not a massive win for you. CooperateBot is much more exploitable.
Totally agree - absolutely no interest in getting a facebook account. Leaves me out of this, I guess.
That would only be the case where people accept tolls & toll booths on roads as an acceptable thing.

Sure, they're common in Canada and the US but in some other countries they lead to years of civil disobedience, protests and eventual scrapping by newly elected governments : http://en.wikipedia.org/wiki/Skye_Bridge#Toll_controversy

Speed fines have the semi-respectibility claim of trying to reduce accidents/dangers on the road (with some validity).
> the current limits on most roads don't represent what speed ... people could safely drive at.

If there's a sidewalk or any t-junctions, that's about 20mph tops. Anything faster, and you can't stop in time, plus in a collision, kinetic energy goes as the square of the speed.

For local trips, with stoplights that slow you down anyway, driving slower adds only a few extra minutes to your journey time.
Personally, I'm not seeing the need to be so hurried all the time.

Yes, or maybe something like a plasma actuator.
In France they have a system that sort of works like this, most/many highways are toll based. There are toll booths at regular intervals(every 100 miles or so). If your time between toll booths is below a certain time, they know you were speeding at some point. To get around this, my always speeding grandpere would just have us stop for gas, un cafe, etc right before each toll booth.

So, where's the github repo ?
The laws aren't put into place with the "let's generate revenue" mentality, but their enforcement is definitely done with respect to that mentality. If it's all about getting people to slow down, then:

1) Why aren't law enforcement more focused on getting people to slow down than writing tickets?

2) Why do traffic cops have monthly quotas for tickets?

3) In places where monthly quotas are against the law, why do 'performance revues' of traffic cops only focus on '# of tickets' as the largest performance metric? (basically a quota by another name)

4) Why is it so easy to bargain down a speeding ticket in a large city, whereas in a small town they are only willing to haggle on the points on your license (hint: because they still want you money)?

I reactivated mine to attempt to get access to the Stellars as well. Its also "too new". Ah well. Still a neat idea, I'll just have no use for it until it matures since I can't use it.
This is great. We use the most primitive part of their functionality which is simply alert the right person through the best channel - whenever a part of our system detects that something is wrong. That's all - but I still love it. Hope they continue improving this - it's not perfect yet.
> One of the significant reasons we started moving away from this kind of development, even before cars became common, is that it traps people inside of them and prevents people from getting into and out of them.

This kind of development is constrained to really make car ownership a reasonable thing (I know I know, he has photos of 3 or 4 cars in some of his examples). So getting into and out of this kind small scale development requires something like rail for interconnections -- I agree buses or trams would be better for intraconnections.

A flashlight in space does propel itself, but that's not really a related question. A more related question is why does a flashlight in a fixed mount inside of a windowless spacecraft not propel the spacecraft (or, similarly, why does a fan inside of a sealed, ventless housing attached to an airplane wing not function as an engine.)

Of course, if there's some way this does work despite what we think we know about physics, its a pretty gigantic breakthrough (well, at least, understanding and practically applying it would be -- otherwise its just an anomaly that provides a pretty gigantic question mark...)

ECC doesn't typically yield that much of an advantage in the nominal case until you get into very large amounts of memory - it's just a more expensive part. I think it was calculated that cosmic rays are likely to cause single bit errors in systems of 8GB of memory only once a decade, and most embedded ARM situations (also carefully avoiding the "p" word) have far less than 8GB of memory. So if single-bit errors are causing your embedded device to crash, it's okay, it'll just roll over and restart... once every 50 years...
The Complete Remote Work Toolset For Distributed Teams
As a college intern at a national lab my boss' boss got a speeding ticket on the military base we worked on. He spent some time doing research and when he presented his evidence in court the judge apparently told him he wasn't going to have to pay the fine but the judge wasn't going to find him not guilty because he wasn't going to risk invalidating all speed gun findings. I don't recall if it was lidar but it's funny the stories are so similar. It's hard to use technology to mess with engineers. :)
Who will sell me their 7,000 stellars for $10 ?
Honestly, I'm impressed that Stripe is that well capitalized. It's an awesome service, way to go guys.
This confused me as well. Stellars are stored in fixed point, as millionths of a stellar. But there's a tiny anti-spam fee for each payment transaction, so if you've sent money somewhere you may find an extra 0.000010 gone.
Yep, you're exactly right--I didn't actually add up the payoffs when I wrote that. You could potentially do better against tit-for-tat variants that have a certain chance of forgiving after a defection, but not against the naive, deterministic TitForTat.
The Hikikomori has become a standard anime trope. Starting in 2009 in Anohana, the main character is a recovering Hikikomori (who went through quite a depressing story that caused him to withdraw from society).

This last spring, there were at least three major animes revolving around the concept. "Nanana's burried treasure", "No Game No Life", and "Mekakucity actors" all have title characters who are Hikikomoris.

Hikikomori (shut-ins / NEETs) seem to be a real problem... real enough that they've entered Japanese Anime culture as a new character archetype.

I don't have much Japanese exposure outside of anime, so I'm not going to draw conclusions based on this alone. But I thought I'd give my perspective. Everything seems to tie together: an economic downturn that prevents many young people from getting a job, the uptick in shut-in culture, and finally an uptick in the suicide rate... (which seem to only cause more Hikikomoris as their loved ones disappear and make life more difficult for those left behind...)
Chile is separated from Argentina by 'the Great Wall of Chile' - the Andes mountains - and unlike Uruguay, has an economy dominated by mineral resource extraction to China and the United States, not agricultural exports to its immediate neighbors.

Yup, obviously a fork of Ripple. While at Ripple, Jed acqui-hired his gf Joyce (SimpleHoney). Then MtGox blew up (Jed still had his profit-sharing agreement with MtGox from his sale to Mark Karpeles). Then Jed announced he was going to dump his 9 billion XRPs ("fyi, XRP dump incoming") because he didn't like the direction his co-founder Chris was taking Ripple.

Then he launches Stellar, the XRP clone. Didn't even bother to change the total token amount (both XRP and Stellar have a cap of 100 billion tokens).

From the Chinese graduate students and professors that I have talked to the problems seems to be that it is really is to commit fraud and get a way with it.

In particular in some fields you can get rich writing grants, getting a considerable amount of money and writing fake papers.

There is a heavy temptation for many to do the same when all of their colleges are able to buy multiple houses and live an extravagant life style. An example from ~5-9 years ago would be a Chinese professor flying to California and buying a multi million dollar vacation house in cash. This is an extreme example and was uncommon even at the time.

My understanding is that this is not the case in all fields, it is easier to get a way with fraud in the less hard sciences supposedly. I also have read about several efforts over the last several years to try and correct matters.

It is also the case that many papers written by non-native english speakers suffer from grammar and spelling errors. Unfortunately incorrect grammar and or spelling often has a negative halo effect for many on the scientific content of the paper.

There is plenty of good science that comes out of China, however it suffers from a negative halo effect from the above sources.
I think it ties into the differences between a guilt culture vs. a shame culture, as those terms relate to the anthropological research. In the western mind, you live suffering with guilt for your actions. In the east you have more irredeemable shame.
LIDAR sucks and there is no judicial notice on it in California. If you ever get a LIDAR ticket, do a trial by written declaration (or TBD). Just state that you dispute the validity and accuracy of the LIDAR reading and they'll usually throw it out. Remember to ask the officer(after he has given you your ticket) what model laser/radar detector he was using, and at what distance he measured you at. Anything over 800/1000 ft(this is really close, and rarely do they get you this close) will usually automatically be struck down if you question LIDAR's validity at that distance. That is a case you will win every time, if you do it right. The court cannot prove it's accuracy at these ranges and they know it. Also, rule of thumb, all CHP officers have laser only on their bikes now.

No RAII would be a big change in the behavior of PHP; you should add that information to your critique. I have code that relies on RAII for error recovery and rollback. Any PHP implementation that doesn't do RAII is going to subtly break a lot of code.

It doesn't make sense to force very specific memory lifetimes for variables and then also not do it for objects.

HN title at 1406825693 is "C.I.A. Apologizes for Penetrating Senate Computers." That is not the title of the NYT story. The NYT title is "C.I.A. Admits Penetrating Senate Intelligence Computers."

The article does mention an apology from Brennan, but not to anyone beyond the two ranking members of the Intelligence Oversight Committee.
Same message and my account is two and a half years old. I have no friends on the account, so maybe "too new" really means "not enough friends".

Edit: Because this is generating some discussion, I'll clarify that it is not actually my main account which is why I have no friends or photos, but I don't like giving third parties access to my private main account information. The spam detection seems to have worked well on me, I was just pointing out that account age is not the only filter.

This can be intentional. If there is a dangerous piece of road where the average speed of traffic is higher than the road will take, then put a trap in to slow the traffic down to the limit. It doesn't have to be over the entire highway system to have an effect on accidents.

For example, in NZ, there is a speed camera half-way down Ngauranga gorge in Wellington - a place where there is a blind turn down a steep slope and where the limit goes from 100kph down to 80kph.

I used to live in Los Angeles. On the freeways, the speed limit was 55mph but I read once that the actual average speed was around 17mph.

My (unscientific) theory is that with higher speed limits, you get more traffic waves, and people try to change lanes more often, causing delays.

If the speed limit on LA freeways was only 25mph, I would hope that people would chill out and the traffic would flow more smoothly, resulting in a faster average speed than at present.

The latter. I've already reached out on Twitter, but you know, contingency plans.
Just like no community has ever been found to be shortening yellow light timers after setting up red light cameras, and no cops ever dubiously search cars for drugs so they can seize assets.

Just because they weren't conceived for a purpose doesn't mean that's not how they're used. Speed enforcement is very frequently performed by small town cops sitting on highways that are just barely in their jurisdiction. They're doing it for money, plain and simple.

See https://www.google.com/maps/preview?client=safari&q=hampton+... for proof of this.

He's simply demonstrating how it started off poorly many years ago.

Yes, many endeavors (sports, music, science, business, writing, etc.) rely on an array of talents and skills. Through deliberate practice we can move forward along these some axes, while others we cannot (e.g. height, for basketball).

But even among the set of mutable attributes, there are clearly individuals who can improve much faster than others, or who can reach further extremes. And sometimes these qualities align in a way that makes a given person extremely capable at a given task. All other factors and external variables being equal, they just have a natural advantage.

This seems painfully obvious; our bodies are diverse, our minds are diverse, and so should be our capabilities. And this is good, as it leads to a well-rounded population. Some people are well-suited for lifting very heavy things, others for running very quickly, yet others for thinking about abstract mathematics, or organizing people, while most are well-suited for doing a wide variety of things reasonably well.

But despite evidence to the contrary, it's enchanting to believe that we could all be the best in the world at something, if we just put in enough time and effort.

The Mill certainly raises a lot of interesting code generation and optimization issues. I'm sure there's plenty of scope for figuring out good optimization strategies, as a lot seems to depend on the ability of the compiler to make good choices about instruction scheduling and belt slot allocation. Sure, that's the case for traditional architectures as well, but there's more prior art there too. There may also be ingenious algorithms which work better on the Mill architecture specifically. I'd love to know if there's any theory on the hardness of allocating positions on the belt, compared to traditional register allocation.
