> using simulated annealing with neural networks

Are you sure about that, or are you basing it on the word "chilling" in the title? My understanding is that Berlekamp's book is all about applying combinatorial game theory to go, and the "chilling" in question has very little to do with the "temperature-decrease" schedule in simulated annealing.

"Chilling" in combinatorial game theory means, in effect, making players pay a penalty for each move they make. The simplest games to analyse are ones in which it's always a disadvantage to have to move; these are equivalent in a certain sense to numbers; the "chilling" operation tends to turn games into simpler games. See e.g. http://senseis.xmp.net/?Chilling for a little more information.

The only connection between this and what happens in simulated annealing is that temperature happens to be a good metaphor for both. In combinatorial games, that's because the "value" of a position changes less wildly with each move in a cooled/chilled game. In simulated annealing, it's because the configuration you're looking at changes less wildly on each successful update as the temperature decreases.
I have noticed a few of my comments being down voted because people disagree with them lately. I feel that they qualified as substantial and weren't blatantly incorrect, but weren't what other people were looking for.

Downvoting a comment should be reserved for comments that we don't want other people to read. Things that are rude, blatantly false, or in general against the guidelines.

I don't think we should downvote things we disagree with, because to some users a downvote says, your comment isn't wanted here please take it somewhere else.

This isn't about points but instead the message you want to send to the author of the comment. If you do want to downvote someone because you disagree, could that instead be turned into a comment that might enlighten them and anyone else reading the thread?

Edit: I don't want to say that these downvotes were unfair, but more about users not following my subjective definition of the real purpose of a downvote which is to discourage conversation on that thread.
I agree that this is most likely to be a capillary-pumped heat pipe. For more reading about how the wicks work:

If I try to zoom, it is already a demonstration that your design does not work for me on my device.

I would not prefer to pan - if I resort to it, it's because I have to because the site design is broken.

At that point you better not have disabled zoom too, if you want me to come back to your site.
I would recommend looking to nature for patterns. Large networks of loosely interdependent organisms work best. Once one species (e.g. humans) become too dominant the whole system begins to fall apart.

There is no central planning in nature. It could be argued that central planning is an unnatural state. A far more robust solution would be to focus on having an economy made up of many small/medium size organizations and individual makers. Currently our economy with our "too big to fail" institutions is very fragile, as single points of failure can have catastrophic global effects. It would be much more healthy to eliminate the possibility of devastating single points of failure.
The return mechanism is via capillary action; surprisingly, heat pipes work in any orientation, even freefall.

Very high g-forces can prevent them working, though.

An upvote should actually be more about wanting others to read a substantial comment, a thank you is more personal to me. It means, hey this really touched me in a profound way (which I might even explain) but I want you to know who it affected by leaving this comment.

Which is why I don't think downvoting is appropriate for them.

When I've had people explicitly say "thanks", that's meant more to me than upvotes.

There's a danger of arms races, and I wouldn't want an explicit thanks to be the default way to express approval, but it does seem valuable to have both available.

(Downvoting thank-you posts is one way to keep them available without losing their value, but I'm not sure it's the best way.)

Likely is an app to help people gather opinions from their friends/family/coworkers or anyone close enough to be on your address book. You create a poll, throw in some choices (even images too) and add the participants, the results are shown in the app nicely so you don’t have to navigate through endless chat messages to know who said what.

If "goodness", aka entertainment value to the reader is what you're judging based on, then yes, I suppose I agree. HN is good for reader entertainment.

In that case, HN is basically the equivalent of a tabloid. Written civilly, while communicating very bad things about whatever it's talking about, while the reader is throughly entertained.

This is more or less the path we take for event matching at SeatGeek[1] using our fuzzywuzzy[2] library. There are places where this falls flat since it's kind of naive, though at that point you can stop thinking about adjacent characters and start thinking about adjacent words.

For the inflation from day one, that is the same story for every country in the Euro zone that had a weaker currency than the Deutch Mark.

The French baguette went from 1.20 French Francs (about 20 Euro cents give or take at the time) to 1 to 2 Euros depending on the Bakery. That's 500% inflation at best on something that is basically the bread and butter of French diet (pun intended).

The Euro zone should have a unified taxation system to ensure a fair competition throughout the zone.

In a small-group conversation thank yous make sense. When there are thousands of people reading the thread, not so much (e.g. it would be weird to say thank you to a conference speaker in the middle of their talk). Upvotes serve the purpose much better - they demonstrate gratitude, they make the receiver feel appreciated, but they don't waste everyone else's time. I would rather not see comments that are just "thanks", even to myself.
Yes I generally agree that this is one of the strongest explanations. Especially if you consider the small spectrum of communication we are examining (and thats just electromagnetic for all we know dark energy may provide a superior mode of communication). I just like the entertainment one because its amusing and sort of describe a great portion of our own civilization. The reality I think/hope is there will always be explorers/dreamers/big thinkers.... I hope.
I know of two occasions where the money was eventually spent on researching some sub 1% effects in particle physics, which the kind of "real" (meaning boring) physics you do today. Of course in that process the exclusion limits for some obscure made up dark matter particle were increased. But nobody in the group ever intended to find anything. However getting funding for some sub 1% effect is almost impossible.

I heard similar things from Astronomy people. You just have to talk to some actual PhD. students and postdocs who do the real work instead of the one professor whose whole job is basically to collect money.
if you use that CA to issue a leaf certificate for your server then you don't need the root CA's password or decrypted private key to be in memory all the time, but then
of course you make generating self-signed certs more complicate (generate self-signed root CA protected with password, and use that to issue a passworddless leaf certificate).
Are you saying that using this approach could lead us the minimum brain wiring to make language work?

if so, I like your idea :)

Of all the dyson products I have (2 vacs, 1 bladeless fan), customer service is the weakest link. The fan has a recall last year, they should have emailed customers shipping labels to print out to drop off the product at our convenience, but rather ask you to visit a local UPS B&M store and the store clerk had to fax the RMA request in. The whole thing took 2 hours on a busy Saturday. Completely failed customer service for a premium product that sells at 5x-10x the price of others. Yes the build quality is good, but not that good to worth 5x-10x the average price for the same product. And certainly not worth the hassles to deal with their customer support.

It's not about lowest common denominator. It's about what devices users are actually using to browse your site. If you make an awesome desktop version of the site at the expense of mobile, but majority are visiting on a small device, then you are alienating the majority. You have to keep perspective of why your are building something; if it is not for the users, then it is pointless.
I wouldn't think those would be noticeable unless you were already closely observing the earth.

I'm not a physicist, but I assume there isn't any detectable, unique signature of an explosion that can be detected from space. Stories I've read about test-ban treaties and non-proliferation efforts give the main mechanism for detecting tests are the seismic effects they have.
There are a number of different ways to build heat pipes. A few of the common designs typically used in cpu heatsinks and laptops do not rely on gravity or centrifugal force. Based on the skimpy page content, it appears they are using the more common wick/capillary system here.

There were many false arrests. There were also many convictions - enough evidence for an investigation, enough evidence for an arrest, enough evidence for a prosecution, and enough evidence to persuade a judge / jury beyond all reasonable doubt that an offence had occured.

> leading to 7,250 suspects identified, 4,283 homes searched, 3,744 arrests, 1,848 charged, 1,451 convictions, 493 cautioned and 140 children removed from suspected dangerous situations[2] and an estimated 33[3] suicides.[4][5] Operation Ore identified and prosecuted some sex offenders, but the validity of the police procedures was later questioned, as errors in the investigations resulted in a large number of false arrests.[3]

7,250 suspect and 1,451 convictions is pretty significant.
Well, latest SSH vulnerabilities came from the official repos as well. Sure, those were bugs not evil modifications, but still.
> hiding the "real" language in a higher-level encoding

Exactly. In the middle of the article they discuss coming up with an expression to mean "car". Of the many word combinations one might choose (they go with "tomo tawa"), one of them would have to emerge as the standard way to say "car", otherwise effective communication would not really be possible. But at that point you've just created a new word. "Tomo tawa" no longer means anything that combination of words might possibly mean - it means car.

I'd suggest there's a certain irreducible vocabulary, and its size is going to be the same no matter how many base words are used to compose it.

I agree with you in that some Enterprises are innovating and pushing the envelope, but it generally isn't global to the enterprise, its in small areas they can accept the extra "risk".

And that kind of problem underlies a growing issue with HN.

>As a rule, a community site that becomes popular will decline in quality. Our hypothesis is that this is not inevitable—that by making a conscious effort to resist decline, we can keep it from happening.

There has always been a push for maintaining quality but more and more users are ignoring everything on this page. In your case that would mean that there's not only a growing amount of people who are downvoting who they disagree with but also that those users are getting a significant amount of karma. The theory is that by the time someone has enough karma to downvote posts they are already trustworthy to vote for content that adds to the discussion, this is starting to break down and it's only going to get worse.
It's written with continue precisely to avoid additional `if (j === hlen)` check after the loop and having a single increment of `j` in the loop :)

To be honest reasoning about the loop with continue is actually easier than about one without.
I think the Happy Meal analogy is a little backwards. When comparing it to workers and contractors, a more accurate one is:

Customers always got fries and a drink with their Happy Meal. Restaurants realize they can exploit their future customers by removing the fries and drink from the Happy Meal, but keeping the price the same. Customers are still hungry, so they're forced to continue to purchase this lesser meal for the same price.

25 quotes for anyone with a dream
I don't see a problem there. The definition of causality is circular anyway. There's no formal mathematical self-consistent proof of causality. It's just sort-of assumed, and then there are back-arguments from relativity that say "Well, that violates something we sort of assume."

The problem is that in science, if you assume things in a naive way ("What goes up must come down." "Planets travel in circles") you're almost certainly wrong - because the details of physical reality are usually counter-intuitive and unexpected.

So what we really know is:

1. Spacetime is a thing. It has bulk properties described by GR.
2. Er - that's it.

We don't know what spacetime is made of, or what you can do with the things it's made of, or what their properties are.

So I'd classify this as "definitely not known due to lack of knowledge" rather than "definitely not proven."

Proposals like Quantum Dynamical Triangulation, Causal Sets, and Loop Quantum Gravity are beginning to ask what spacetime is made of, but they're barely in their infancy.

The one thing they have in common is the idea that there's a network of - something... - and the reality we recognise propagates across the network.

If the elements are discrete - and they almost certainly are, because of the Planck limit - there will be some moment where an element changes state.

How fast does that happen? What's the mechanism? What limits the state changes? (Adjacency? Some other property?)

It's completely mysterious, and I think it's unwise to make definitive statements about it until it stops being a mystery.

I am the OP. Yes, that's the same reaction I had when I first noticed it. The funny thing is, they aren't even backing their "premium LED lighting" product the same way they did for vacs, which has 5-year limited warrant. LED lighting gets only Free 2 year limited warranty, even though they claimed "37 years" of lift span based on some calculation. One might wonder, will they still be around in business after 37 years?
If by "a few years back" you mean 14 years ago with the quake/quack thing.

But nobody is saying this is the cheating-style "optimizing" which has been judged as invalid. Both Nvidia and ATI do heavy amounts of game-specific optimizations in drivers and so long as there is no visual difference this is perceived to be fair and valid optimization.
Yes it is. Although, is .Net fully open sourced yet? or still in the process? I'm not so sure you can build an IOS app quite yet in visual studio?
Not necessarily. All other things being equal, a startup can enter a big market that is 1) fragmented 2) the start-up has few or weak competitors. I think what a start-up is looking for are big untapped markets.
