My experience has been really similar to yours. I also was plagued by perfectionism, reworking things endlessly when I was younger. A beer makes it go away, commit to a design decision that is not necessarily ideal because it probably doesn't have to be ideal, and move forward.

I find it helps me focus as it stops my mind from wandering off down infinite stacks over minor issues. Like caffeine though there's a certain precise narrow level where this happens and if you go over that level it doesn't work.
I'm curious what they were thinking about investing in. A trading site like Tradehill? Or something a bit less risky?
Assuming bitcoin does need its crypto upgraded at some point, probably what will happen is some people with a good deal of bitcoin authority, like the "official" bitcoin developers at bitcoin.org, will upgrade the crypto, and everyone will follow them, because they can be trusted.

Yes, the hash algorithm can be upgraded as computing power increases. This was foreseen and built into it from the beginning. The implementation is relatively flexible, and can be modified or upgraded in a number of ways without having to restart the blockchain.

Development of the technology is pretty active, you can observe what's being done on the development mailing list at Sourceforge:

That's just a random sample from Gavin, but if you're curious take 30m and read through to get a sense of what their issues and priorities are. The current issues list and recent change logs are also instructive;

As with many things in history, I don't think there is a single year that we can point to as the turning point, since it's a somewhat gradual shift.

Think about it this way - a few hundred years ago, it was commonplace to pay dues to the government using precious metals (like gold). In some parts of the world, this is still the case, but in the majority of the developed world, public and private debts are paid with money that gets its value by fiat.

This change can't happen overnight, even if you force it to; if people continue to accept gold (for example) has having liquid value, then it will continue to be used as a currency.

I wouldn't even use the beginning or end of Bretton Woods as the turning point (though it was certainly a turning point), because the point is less whether people can convert currency to gold than it is a question of whether they do.
All my friends who live like that have a rather sour disposition, so I'm guessing not.
> Your review will be decorated with an Amazon-style "This review was helpful" thumbs up / thumbs down button; and, the more helpful reviews you leave, the more weight your later reviews will be given

This is exactly what I've been thinking for the past 6 months. There's no reason the rating given to a business should be the generic average of reviews provided. A weighted average considering various realistic factors would provide a much more representative rating for a business.

I hate to do this sort of self-marketing, but issues like these are exactly what I'm trying to solve with my startup (skipscotch.com).

Very interesting idea about gaming the review platform. I'm trying to game it a bit, but the idea where reading reviews require credits you earn by writing reviews is a interesting concept. I just wonder how much of an audience you would be limiting from your platform by implementing it. I suppose you could allow anyone to view ratings, but actually reading reviews would require credits.
Giving them more time is the right answer.

You ask what changed? You seriously underestimate the kind of China has gone through. China over last 30 years has seen changes that were monumental. Literally, millions and millions of people can now feed themselves with 3 meals a day. China has never been as prosperous as this before, and things are getting better.

Keep in mind that all the horrible things you mentioned are not unique phenomena historically. All those things were there in abundance long before industrialization took place in China. Therefore, these phenomena are not results of industrialization. In fact, more industrialization, more modernization, freer market, removal of notoriously bureaucratic China's communist government regulatory hurdles are what would make China prosperous.

This is quite similar to Shogi, a Japanese variant of chess where you can put down any of your opponent's captured pieces. From what I know, that game is highly strategic; since all of your potential pieces come directly from your opponent, it's probably less chaotic than this variant.

This is an interesting point - I suppose it shows how sophisticated the language of mathematics is.

I think its not perhaps the 50 lines that matter though (most of this is just effectively defining what the mathematical symbols and grammar mean), but the one line, which can tell you how everything relates together very effectively..... this is what the python version misses to me...

Seriously. I think you could golf NB into 2 lines pretty sensibly once you've got the data in. It's really just compute two histograms, multiply, and maximize.
Agreed. Societal norms are needed to build the trust required for all large enough groups to function efficiently. This is why there is less crime in mono-cultures: everyone is a member of the same social order. The danger is that agents outside of the particular social order (hackers in this case) aren't bound to the rules within that social order.
While I agree with this statement, that technique is more important than superficial or trivial language decisions, I think there is a second level of reasoning that needs to be brought into play here.

Once you know several techniques and several languages, and have started to get a skill at identifying the core bits of a project, the process (or series of questions to answer) becomes:

- what technique will effectively handle to core problems?

- What languages make this technique simple to implement?

and then the real kicker, which in a way comes full circle to the original naive analysis:

- in the best language for $technique, are there any problems with secondary and ancillary problems associated with it? (e.g. i have to do this really fast lookup table of simple operations, C would be great for this, except that the data is irregular and involves a lot of string parsing C sucks at that..., or the central problem here is just a big fold, i'll use Haskell, but it involves a lot of tricky memory optimization to be fast enough...)

Out of this of course arises a meta-technique of learning to partition problems into stages in different languages, which of course has its own problems.

The details of DDG's arrangement with Bing are obviously not public. However, it is a very safe bet that DDG either gets the information for free, or essentially for free, simply because to do otherwise would make no sense for Microsoft. Microsoft benefits from anything that even potentially reduces Google's market share, by any amount.

Of course, that puts DDG in a dangerous situation, since it depends on Microsoft. Perhaps it has a long-term binding commitment from Microsoft, though, that wouldn't surprise me either.
thank you so much for this. im going through the tuts now and loving it. you have any suggestions to where to educate myself in when I complete them?

It might be even more beneficial to read good code then try to find a way that it could've been done better.
I love the execution on this, turning what was otherwise a normal billboard into something that's much more interactive and useful. What stands out for me are:

- They tried to duplicate the look and feel of being in the supermarket, allowing customers to navigate naturally in their browsing and shopping habits. Don't underestimate the power of routine/habit and creating experiences that are familiar/comfortable.

- They also deliver the groceries so it completely replaces the need to make a trip to the grocery store which is a time-saver.

- This works well in areas of high smartphone/internet adoption rate like South Korea and Japan.

I was thinking about whether or not this idea would work in San Francisco/Bay Area given the high mobile adoption rate and young tech-savvy crowd. I would focus exclusively on fresh produce given that these are often the most expensive in stores and its risk of spoilage leads many of us to not buy as much as we should.

Ask HN: Would you shop via a BART/Caltrain/Bus Ad using a smartphone app for groceries if the price as more competitive than Whole Foods and you got free delivery to your workplace/home?

Not ready for prime-time. Not even close. I wonder if they ever tested their query engine, it's hardly useful. No quotes? Queries ignore important characters like "_"? No roll-up of identical results? It also misses methods in its "(num) methods" results (or throws them into a totally different order) in several languages, and has some crazy match-ordering behavior.

An example: I searched for "helper_method" (a Rails method), and found these (bracketed what was bolded as the search hits):

class.Scheduler.php:
// Holds [method]s for ...
Editor.py:
from Models import Editor[Helper], Controllers
AutShare.h:
// IShare [method]s

and then I get over a dozen literally-identical files called "helper_method_example.rb" (tests with these results:

require File.dirname(__FILE__) + '/spec_[helper]'

describe "a context with [helper] a [method]" do
def [helper_method]

and the rest of the files contained this after those lines:
"received call"
end

it "should make that method available to specs" do
helper_method.should == "received call"
end
end

There are about three pages of results like that, or the same wrapped in a `module HelperMethodExample`, with identical contents otherwise.
This is naive in the extreme.

We all live in nation-states and are required to abide by their laws as a result. Though it's theoretically possible to separate currency from governments, if that's not what the governments want, it will never be legally permissible. As it is, Bitcoin operates in a legal gray area. That's not going to improve.

Most of the VCs I talked to about FaceCash refused to invest because they were afraid of the regulatory implications. But throw in some bad economics (verified as such by Paul Krugman, see http://krugman.blogs.nytimes.com/2011/09/07/golden-cyberfett...), a catchy buzzword or two, and some political philosophy, and you've got yourself an investor?

Venture capital is even more broken than I thought.
I'm near the end of working my way through A Quantum Mechanics Primer, http://www.amazon.com/quantum-mechanics-primer-Introduction-..., and I have not attempted to tackle the PBR preprint, but based on Scott's interpretation of the central point, I don't get the significance of PBR. If two rational people assign different states to the same quantum object, and a measurement reveals an eigenvalue that could only have been associated with one state, and not the other, then one party was just plain wrong. Also, you only get to do one measurement, how does that prove the state was previously pure or mixed? Don't you need a prior knowledge of how the state was prepared to decide that?
I disagree. I have done exactly what the author did and got drunk before having to send emails. I sent emails I would have never sent sober because I would have been too worried about the implications.

No one is around judging you or knowing you are drunk, you are just writing emails.
Even more problematic, I tried searching for zmq_init, to see if it would be useful for finding how other people had used a specific API function, and it seems like it treats an underscore just like a space. Not one result on the first page contains "zmq_init" in the summary, it just matched "zmq" by itself for all of them. I'm sure some of them do contain zmq_init in the complete sources, but that's not what it's matching, and for a less common API function, it seems likely a regular google search would be more productive than this.

Hopefully they can fix that, just having a bunch of source code indexed, or even available to be indexed if it turns out the current indexing is no good, is a good first step. But it seems like it needs work right now.
my apologies. thanks for pointing out. I'm not so good at english.

you make some good points, but most of this is just uninformed opinions on various google products.
This seems to assume that the only way to use a network is the current (near)instant req/resp style networking, which is core to a lot of current protocols. One of the things a darknet would enable is a slower eventual delivery model, like email used to be. This is not ideal, but opportunistic store and forward still can move information faster and easier than no network at all. Things like freenet and freedom boxes are attempts to look at this notion.

In scenarios where the darknet is being actively attacked, people are likely going to be less concerned with instant services than any source of reliable, uncensored information. Perhaps we need to really look into ways to get information around following these methodologies and constraints as a supplement to building darknets.
Why the gloom and doom should be considered as opportunity in business
This could be interesting as a secondary display. There are lots of ingesting things to leave running (dashboards), and a big tablet for doing some kinds of input.

Plus, games. Both as an immersive input device in regular games, and a great party tabletop games platform.

Higher resolution than 1080p would be nice for such a large panel. Figuring out a way to give haptic feedback (screen vibration under input area) would be nice too.
Man, I played this back in high school when I was on the chess team. It promotes such a different level of thought than normal chess, but when you get a teammate who literally starts taking pieces so you can place them and vice-versa, it gets insane.

I think the real benefit of this game is that it teaches you to read chess boards quickly. If you get good, you can glance at your opponents board and get a quick idea of things you can do in a few moves to help them.
It's so true. Though I haven't been nearly as immersed in the Clojure community as Anthony has, two of my last four jobs/internships have been in Clojure (well, really, they hired me back). And I've loved it. I love the language–it's the perfect balance of having fun, being precise, and getting things (anything done). And I love the community. I've met so few Clojurists in person, but the ones I have met have been amazing, and the ones who share their stories and their wisdom via blog or IRC are just so damn intelligent and kind.

More than anything, I Get Things Done with Clojure, and the community helps me do that. And from the feedback/re-hiring I get from my jobs, my employers and the people they serve would agree.

Anthony: Keep at it man–you're great!

> I caught myself doing ^T and typing "!w keywords" (to search wikipedia) on other people's computers more than once by now.

You realize that you don't have to use DDG for this, right? You can set up keyword searches in the search bar in Firefox or Chrome (don't know about other browsers) for any site, not just those that DDG supports. Then just type 'w <search>' into the location bar and hit enter for Wikipedia, for example. You can even do cool things like set up custom searches, like my 'wl' search, which automatically prepends 'list of' to any Wikpedia search.

Over what years do you think this shift occurred? Or put another way, you do realize that fiat has been in use at least since the Romans?

Sun free photovoltaics only work with high-quality heat - heat produced at around 800 degrees Celcius, typically by burning a hydrocarbon fuel [1]. They're not capable of gathering waste heat and converting it to electricity.

[1] I'm currently working with the lab from the research article above; if you re-read that article, it explicitly mentions fuel sources a few times.

What you describe and what shocked you is daily reality in most developing countries--poverty is ugly.

During the next 2 years will be the handover of gov't to the next president and it will be up to him where China goes: the way of Brazil and many African countries with a Gini-Index of 70 and above, or a society with more social equality like the US or even Europe.

However, I have become rather pessimistic in the past two years if there is even a chance for the next president to push China towards more equality. Because that would mean paying taxes and rule of law for the rich. And the rich will not like that.
What happens if someone releases bitcoin2? right now bitcoin exists as a unique entity, but with competition what happens to it's value? bitcoin to me seems like how beenie babies were to moms in the 90s.

Plus I don't think I'm ever going to be able to get over how lopsided bitcoin favors early adopters.

Making semantic line breaks (such as for bullets) is understandable, but it still feels wrong that we’re otherwise doing the job of `fold`. I started breaking lines in commit messages because it’s convention, but I still believe this is a tooling issue.

Check the publishing record label for the song, album, or band in question, then check that against the list of RIAA labels (I seem to recall finding such lists in simple, textual form). There's also RIAA Radar:

Objectivity is irrelevant and impossible in this context of raising awareness and fun. If the mechanism was something as simple as an upvote next to the commit message, you would let the community define usefulness of the commit message.
Heh, yes, I can confirm this. The one time we met you said that you weren't sleeping well (since school had just started) and, as a result, were talking more than usual.

Whenever I'm low on sleep, I'm mostly just irritable and more prone to making mistakes, although once, when particularly sleep deprived, I found myself reading the back of a shampoo bottle as if it were a cooking recipe. A couple minutes in, I realized it wasn't a recipe, thought to myself something like "Snap out of it!" Not more than five minutes later and I was reading the "recipe" again.

Anyways, personally. I'm certainly neither more productive nor more talkative when sleep deprived.
I think there are Statements about those things precisely.
People are only going to buy the equipment in the first place if they can check their Facebook over it. A network that's designed only for freedom fighters ends up not getting enough nodes to reach critical mass (see Freenet). People might tolerate an Internet-incompatible network if it also came with lots of free warez, though.

I like the idea but feel it's an echo chamber. I haven't seen a single surprising ranking yet.
This is the truly principled stand -- not because of any particular squeamishness about "piracy", but because piracy actually helps the RIAA labels to a significant degree by serving as free advertising.

China's younger generation: lifestyle counts as much as work
Here's one that struck me: "Its earlier attempts – Orkut, Buzz, Wave failed." It's true that Buzz and Wave failed, but Orkut is very popular - in Brazil and India. Not being popular in Western countries != failure.
What is a password, anyway?
Pirating still serves as free advertising for the labels, and gets people angry at you.
Its simply too costly to get the optimal size cab to a customer today. So cabs are usually much bigger than the average car. Flexibility is more important.

And cabs make up a small percentage of the overall market. And most of the cost of a cab ride is labor.

But if automated cabs become the norm, the cost of a cab ride will be governed by the size of the vehicle. And if a car costs 25 cents a mile to operate, a cab ride from my house to San Francisco will still cost me $11.

If a 1-seater with barely an engine and no trunk can do it for 10 cents a mile or $4.50, there will be demand. That's the commuter, the guy making 40 trips a month, who'd save $260 a month for giving up empty space.

Of course, we really don't know how this will all play out. But it will be fun to find out.
I don't think gp is suggesting using people to generate electricity through exercise. Finding a way to harness energy released when lots of people are exercising anyway (i.e. at a gym) might generate an appreciable amount of energy, with no change in human behavior.
