Technically, you're right; the electricity used over an ASIC miner's lifetime is very little. The OP has the right idea though, even though the reasoning is wrong. It actually comes down to whether your mining unit can cover its capital investment.

If it weren't for the huge price increases, all the people who bought ASIC miners would be underwater right now.

I have a 60GH/s BFL miner. It uses about 350W or so. The fans are LOUD. When I get home the room it's been running in is noticeably warmer.

They don't generate as much BTC as one might think - just 0.04 / day at current difficulty and this is decreasing at a rapid clip (1 month ago or so it was 0.11 / day).

As an aside, I've always wondered if one day all heating will be computational waste heat. You could almost give away ASICs (whether for mining or other purposes) to people in cold countries and subsidise their electricity when they run their heater...
This is dope! I will be downloading this as soon as I get home.

An exchange shouldn't be vulnerable to bank runs. All of the money (USD, BTC) should be there all the time. They're not loaning it out. For that matter, the exchange shouldn't care what the price is. It's all just shiny beads to them.
The net is soooo ripe for a distributed replacement of Youtube, Facebook, Gmail, etc. Once upon a time those sorts of sites provided real value in hosting files, pictures, video and providing a well-known endpoint like gmail.

But now we have phones with 64GB of flash for canonical storing of files, p2p protocols for efficient transfer of files and distributed hash tables for finding files. Someone is going to come along with a distributed system that gains enough traction and just wipe all of these guys off the map.

To paraphrase the founder of RedHat, whatever comes next won't be the size of Youtube, it will make youtube the size of a bittorrent tracker.

It's fairly trivial to load jQuery/other libraries from the Google CDN and fall back to a local copy if it fails as long as you're not using async/deferred.

We've got it baked into our boilerplate.

If Google decides to charge for use of their CDN, then I wish them luck. They don't have any billing information and short of serving a bastardized jQuery (simply not serving it will trigger the fallback) our projects will continue as they've always been.
I made a nicer version of this to browse for the ICML 2013 papers, based on a similar thing Andrej Karpathy did for the NIPS 2012 papers: http://benhamner.com/icml2013preview/#/

You are correct, of course. I agree and think Apple should change their policy regarding non-app specific digital content. However, I believe Apple should simply lower their payment split down to 5-10% and behave more like a standard payment processor attached to your Apple ID.

Amazon should then be allowed to increase their prices on iOS to compensate for the difference. I would happily pay a little extra per-purchase to keep all my purchases under one account, using one interface, and would be happy to take advantage of Touch ID authenticated purchases across stores.

I still do not like the idea of purchasing on iOS outside my Apple ID. It is quite outside my comfort zone to purchase within an app using a different UI, trusting my details with a different provider, and so on.

Regarding handling returns: one of the main complaints I have heard from Android developers is the influx of emails they have from customers asking for refunds, and having to process those refunds. While I agree that it could be used as a promotional opportunity, many developers view it as an unnecessary burden.

Next step is to get humans to write the articles based on those titles, and then auto-generate fake comments based on those articles.
When I read the title I thought this would be about space walks. Having heavy boots would help create a greater gravitational attraction to the space station, making it harder to float away.

It's interesting to consider the forces involved. At 10m, with a 100kg astronaut and a 15 ton space station the gravitational force is about 1e-7 Newtons. At that acceleration, if the astronaut kicked off at the speed of 1cm/s--or 36 meters per hour--and assuming the force doesn't change, it would take about 24 days to get back.
Personally, while I'm almost frustrated enough with YouTube ads to use an ad blocker, I'm hesitant to do so because the authors of the videos I watch are often precisely the kind of people I want to support, and I've heard YouTube is hard enough to depend on for income without people blocking ads. I'd love to have an option to directly pay money instead, but I doubt it'll ever happen.

Twitch.tv is similar but considerably more annoying - but it provides such an option, and I'm considering buying it, although (unlike YouTube) I probably don't watch enough Twitch videos for it to be worthwhile.
Definitely, but my argument is that OSes must account for the shared-server case, but in practice many servers are dedicated to a single service.

Supposing you built a memory manager exclusively tuned for PostgreSQL, with the assumption that it has the machine to itself. That memory manager would have a different performance profile from the kind of "veil of ignorance" that a general-purpose memory manager has to cope with.

> It's interesting that the website seems better than the average GNU project, notably the look and community parts.

As a GNU Octave dev, it makes me feel sad that "GNU" no longer has the cachet that it had in the 90's and early 00's. It went from being a mark of quality to being outdated, disorganised, and lunatic.

Oh well. I still support GNU. Hopefully you'll like the new GNU Octave web design we're working on.
Yes they do. Mt.Gox gets the transaction fee.
eh you lost me, man. he still has the option to only take USD or use a 3rd party payment processor. At the moment, it seems that this approach is not costing any businesses in sales, since Bitcoin is still used infrequently as currency. The only point it actually becomes a currency itself is when the shop owner stops using a 3rd party processor and says "you know what? I'm comfortable just holding onto these". With the market volatility of Bitcoin this is unlikely to happen for a while, unless they are among the believers who think the value can increase indefinitely and accurately represented by trading prices.

I definitely understand the value as an infrastructure, but this is the web. Better solutions will emerge and could just co-opt the Bitcoin infrastructure. Like the way ISPs came in and bought access to the data lines of phone companies, same idea.

This is an interesting case study in how the submitted headline affects the page's rank on HN.

I'd originally submitted this earlier today, with the headline "Neural Information Processing Systems (NIPS) 2013 Proceedings": https://news.ycombinator.com/item?id=6815771

It only got one other upvote and never made it to the front page. Meanwhile, another article submitted at almost exactly the same time with far less interesting content but a more provocative headline (on a user getting banned from Uber for API abuse) got ~15 votes, pushing it onto the front page.

I re-submitted this page with a slightly more descriptive (and buzzwordy) headline ("State of the art Machine Learning papers: NIPS 2013"), and it almost immediately ended up on the front page. Since then the headline has been reverted to the page's headline, again slowing the rate at which it's received votes.
Here's one example use case where the ads are horrible: playlists.

Youtube has these "top tracks" playlists. When I discover a new artist, I'll often put that on and go do something else.

If a rollover ad comes on, I have to come back to the computer, and click the "skip" button, since I'm not sitting down.

One thing I was wondering: does the content creator make money when I skip the ad, or only when I take some kind of action based on it?
Sounds like MtGox is hoarding. Seems that if they increase the delay they can cream of a percentage of the money and keep trading and that they benefit from the rising price by paying out slowly.

How trustworthy is MtGox?
Maybe they're just testing your interest. If you really want to work for them, apply again. That may just be a part of the process.
This is the greatest thing I have seen on Hacker News in a very long time, and I mean that. This is genius, the titles that it generates paint a pretty clear trend of topics HN likes to discuss: The New York Times, failure, Go, PHP and of course limited to 2013, the NSA.

Some of my favourites I've generated today include:

It looks like it should work, but the tolerances and tensions required make it unlikely to ever actually work. For the model in the article to work, the inner gears (in red) need to be A) Loose enough that the blue shaft can pass between them B) tight enough to pass power from the interior of the wheel to the exterior. This is improbable, and, while the solution seems sound, it's never been shown to work; It maintains mythical status.
Credit card purchases are charged the official USD exchange rate ~6 ARS + ~20% (the real exchange rate, or the one everyone accepts in the streets is ~10 ARS). The government will pay the difference for no logical reason, consider it an irrational player. And for even stranger reasons people don't realize this, and they also think Bitcoin is a scam, no matter what you tell them. Therefore nobody does this Virwox trick and it stays under the radar, undetected for years.

Let's just be crystal clear about this, people are doing it. The prices would be vastly different if they were not. This route could be direct or indirect, but it's happening none the less. At this point you won't get any money out of Mt. Gox unless you have a JP bank account, which requires physical presence there.
Ask HN: Multiple currencies with paypal

If you think it's so easy, then you build it. Some of that has been done, some of it has yet to be done. But so far it sucks compared to the centralized system.
This could be describing the Philippines. A large number of people don't work because they don't really have to. OFW remittances send enough money back in some cases that the local economy makes it seem pointless to work (unskilled workers here might make $3 - $4 per day.) In other cases, the family has built a compound and everyone can live super cheap there. Maybe there is enough money flowing into the family that nobody has to work.

I see a lot of drinking, fiesta's and festivals here. Given the idle time, it seems that most don't pursue education or other things which could further them. I suppose many of these people would choose to go to school if they could afford to do so.

This may be a decent end goal, but I can't help but think there is always something that someone could be doing to make money. There is always more that needs to be done. I can see the "suck" all around us. Things which could be improved.

If we were to ever be able to get large numbers of people off this planet then there will always be much more things for people to do. We could explore further and expand outward.

For the foreseeable future. If you are in the U.S. you either work or you collect food stamps which barely cover you. It would be great for one person to support 10K, but for now, the less fortunate have to ask from people who are far less able to provide (family who is getting by, but not doing great otherwise.)
Actually, it's your own "bias" that seems to show through here

I'm intrigued! Which bias do you think I'm showing?

It's true I'm doubtful about the prospects of Jolla - but I'm not sure I'd characterise that as a bias exactly.

It's true that I remember Maemo (and more broadly, Nokia). I think there are lessons there, but I'm not sure that is a bias either.

I saw Soylent mentioned on the first page, and then this para from the NYT's Well page stood out even more starkly:

>> "Last year, in its nutrition guidelines for cancer survivors, the American Cancer Society noted that eating traditional soy foods — like tofu, miso, tempeh and soy milk — may help lower the risk of breast, prostate and other cancers. But the guidelines do not recommend soy supplements, which tend to be highly processed and not very rigorously tested."

http://www.nytimes.com/blogs/well/2013/09/27/ask-well-is-it-...

It's not possible today because the infrastructure just isn't there. You'll experience trading lag which is just too risky and it offsets the profits. Also, getting money off an exchange takes forever.

Someone organized a fund on bitcointalk which tried to arbitrage prices on mt.gox and bt-china (This is cumbersome because you need physical presence in china to be part of bt-china). It sounded promising but it failed and everyone had to be refunded.

https://bitcointalk.org/index.php?topic=330209.0

In fact, the reason the BTC price on Mt.Gox is so high is because you can't get your money off there in a reasonable amount of time. This means that to get your money off of Mt.Gox you do not send a sell order to convert to USD, you instead transfer the BTC to an external wallet and sell it elsewhere. This leads to more buy orders than sell orders on Mt.gox (leading to higher BTC/USD prices).

The post makes a good point about the distinction between two types of text - symbols and human text. Sadly, this is made very complex in our world through the introduction of the markup (and markdown) languages which mix text targeting both machines and humans.

Off the top of my head,

1) Anything low level hardware (reading data via USB, or pushing data into HDMI, for instance)

2) Interacting with ANY hardware that's not explicitly supported by Javascript. Try creating an HTML5/JS scanner app.

3) Writing super-fast CPU-specific code, think Assembly language. That's the reason there are no HTML5 apps of the Photoshop caliber.

4) Disk access. Try creating a Javascript-based antivirus. Or an app that watches for changes in a certain directory.

5) Internal network access. Try writing a JS app interacting with your localhost or TCP/IP or UDP.
My parents have been telling me this for years. I'm glad I listened.

You can release some software that contains both GNU GPL and BSD-licensed code, and it will be legal to distribute as long as you follow the rules of both licenses; as the rules of these licenses do not conflict, there's no legal problem.

This is what most people mean when they say two FOSS licenses are "compatible."
The problem is that you don't understand Scala operators. There are none. That + sign there is simply the name of a method in the class of the object preceding it.

So you invoked print("5".+(5))

What else would you expect. The nice thing about Scala is that you can leave out some of the extra syntax that is not needed for the compiler to decode the meaning.

Now as for why the String class has a + method to do string concatenation? I don't know but this is far from the first language that I have come across that conflates string concatentation with numeric addition. Maybe it comes from the Java libraries? In any case, it is not really a problem to most people because we follow the maxim, if it hurts, DON'T DO THAT!

What do people think about this product? I have done egro before but didn't really help.
There are very few assignments in the Army that involve coding on a regular basis. In fact, most people who spend 20 years in the Army as IT specialists end up leaving without ever learning anything at all about programming that they didn't teach themselves in their spare time. Many of them don't know much at all about computers either.

One of my IT instructors thought that anything involving a command line was part of a programming language called Unix. Before he became an instructor, he claimed to have held a full-time job as a software engineer, which involved nothing but generating reports from a SQL database.

The majority of the IT work in the military is Help Desk and low-level system admin and network admin stuff. There are exceptions, and there are some interesting assignments, but they are rare and getting one is often a matter of luck.

Military service can be rewarding, and its a good way to fund an education, but its definitely not for everyone.

Coinbase is nice, but dealing with their support is not a fun experience at all. For about a month they held about $2000 of my funds due to one of my purchases being marked as high-risk.
