Firstly, USD, being the world reserve currency, has value because of its current ubiquity in international trade, NOT because of its legal tender status in America.

FYI: "Legal tender is currency that cannot legally be refused in payment of debt. Private businesses may adopt their own policies on whether or not to accept cash as long it doesn't violate state law."

So when you say this: "all governments and businesses can not refuse to be paid in dollars"

You've misinterpretted the law.

And when you say this: "Thus, if you try to pay me in Bitcoins in return for mowing your lawn, I can laugh in your face, but I can't refuse your dollars and demand that you pay me in Bitcoin."

head asplode!

This is just utterly mind boggling. In what world does a service provider HAVE to accept whatever payment terms the customer demands of him, even if the customer demands something the service provider never agreed to in the first place? If I'm a business, and I tell you I'll provide X service for you, but only if you agree to pay me in BTC, and then you turn around after I'm done and say "HAHA J/K LOL here's some USD", I have every right to tell YOU to fuck right off.

"as long as it remains illegal to pay salaries in Bitcoin"

Talk about painful levels of ignorance. I would love to see you try to substantiate this utter falsehood.

"because I can be 100% certain that I can buy the things that I want in dollars"

Let's revisit this sentiment in 25 years.
> Like the implication is that we must have an exponential increase in cores in order to accommodate a linear number of users...

As the article says, you can just ignore those extra cores. But, if you want to do cooler stuff with your data you'd better use them, and if so, sharding is a dead-end.

> More generally is anything about this approach really novel?

I said it's a repurposing of an old idea, that of the old RDMSs where the application was the database. The idea is not about concurrent transactions but about uniting the application and the database and letting the database run and parallelize the application's logic, and be the engine of scaling. I think most people see the database simply as a data storage component, and try to make it fast and scalable enough. We say, let the database run the application.

> And ruling out concurrent languages that are capable of implementing this approach...

I haven't ruled out any language. In fact, the demo is in Java, which certainly doesn't qualify. Any language can do this. I only said that in order to go forward, in order for the common programmer to take advantage of modern hardware, we must use languages built specifically for modern hardware. I've named two that I think fit the bill, but if other languages end up becoming the language for the new age - it's all the same.
It is intrinsically delayed because it's based on the deltas from the previous state, and also they show a feedback loop in the filtering phase.

In one of the example of the color amplification you can see the head moving and a little bit of lag between the two sides, but I can't tell if they have been intentionally synced or this was done truly in real time.
Good suggestion, I changed the link.
JUnitBenchmarks: Code benchmarking in JUnit4
Go read "Foundation" by Isaac Asimov and note the description of Hari Seldon's notepad. I believed it was written in the 50s, but Wikipedia says 1942. (Maybe 1942 refers to a short story that became part of it.)

In WWII Douglas Engelbart was trained as a radar operator. After WWII he is exposed to computers (driven by punchcards and tape, and emitting printed output) and immediately thinks "these should interact via cathode ray tubes".

It seems to me that anyone with imagination who could grok what a computer was immediately imagined the computer being embedded in any information device they could think of -- whether it's a watch, a notepad, a telephone, or the human brain.

The "light pen" was invented in 1952. Do you think the inventor's "vision" was that it be part of a monstrously big, complex, and expensive piece of hardware? (Do you think he/she hadn't read "Foundation"?)

London has a pretty bad homelessness issue. There are lots of charities and voluntary contributions that attempt to address the issue but its a hard problem to solve.

London also has quite fragmented social ghettos. In most cities you have richer areas and poorer areas, London broadly has this, but has pockets of wealth in the poorer areas and pockets of poverty in the rich areas. To a much greater extent than I've seen in any city I've been to.
Intel drops a Big Data shocker
I just searched for a few of my favourite Metal bands and didn't find them on iTunes! :( A quick Google is telling me iTunes doesn't support buying lossless codecs.

One thing I have been trying to do recently is sending messages to bands I like asking to buy a CD from them that is signed. I get to show my support for a band I really like, and I also get something more than just the CD.

As for TV, I have a TV license in England which allows me to stream TV and 4OD is pretty good. I tried NetFlicks but I was unimpressed by the selection available. The problem is that streaming real HD movies/TV is not particularly easy, and no service I have come across lets me download them. I could rent BluRay's from a place like LoveFilm, but I don't have a BluRay player...

I would willingly pay £30-40 a month for a legitimate service that lets me download full movies/tv shows in 1080p .mkv format and keep them to watch again at another time.

edit: I'd like to point out I want REAL HD. iTunes/Android/YouTube/etc offer horribly compressed 720p videos with lossy audio. <--- Quality freak here.

I'm not sure I agree with all the logic in this article?

Higher Prices: This is not a deregulation, surely it would make AT&T have to compete with other VOIP services? The issue are the necessary safety/security services and hiw these are not well governed in the TCP/IP world?

Service Disruptions: I can't see how both AT&T and smaller operators both using public IP would disrupt? I think there's a trade off between between price and quality of service, those that go with a Cadillac service vs those that know they are getting a slower service albeit at a lower rate?

Inequality and discrimination: This on eis an issue, it's the Governance of "essential service", My sense is the legislation needs to change to a) Force this be be carried over IP (I know there are technical issues) b) Subsidize or keep a lid on prices?

I also prefer OS X Lion's scrolling, and tried to get it to work in Ubuntu. The solution I tried was xmodmap, but it turned out that this isn't respected everywhere (notably, a bunch of GTK programs ignore this), which means that scrolling direction then depends on which window you're in, which is worse than nothing. :(

For now, I've given up on Linux on the desktop. I even liked Unity, except for how slow it was, but after trying Windows 8 (first Windows since W95!), I've switched for desktop use. Maybe I'll swap out my Air for a Chromebook Pixel. ;)

CSS Selector Performance has changed! (For the better)

http://calendar.perfplanet.com/2011/css-selector-performance...
The tech startup system was for monetizing publicly-funded research. As I understand, you don't get funding for competing with companies in industry. At least I read things from people like Knuth, who mentioned that a company was angry that TeX was backed by public funding and competed with their product.

Many academics do desire to build product. But would they get funding? Maybe someone in academia could chime in.

World Changing startup seeks hacker co-founder
Hey all; seeking a co-founder for a company that's going to eat the self-help AND nonprofit industry, while killing outdated modes of "helping people" and replacing it with an online hub that will make mucho money (business model is solid!) AND help millions of children & adults be happier. Looking for A++ hacker with back & front-end experience that ALSO loves to brainstorm, refine, and take ownership of ideas; must have strong belief that youth and adults can change their thoughts & behavior; and that it can be taught.

Want to hammer this out this summer. I'll teach videos & raise capital 60+ hours a week; need someone to create kickass, gamified, fun-as-hell ruby/other site.

If not from NYC; I have free housing for summer months for ya. Serious.

About me:
Former founding Executive Director of a US Dept of Education Funded nonprofit; educated at WashU leading schools of social work & business; have raised over $2 million in start-up environment, managed team of 4 full-time 3 part-time. Have strong networks in education, nonprofit, and self-help communities in NYC.

More importantly, I have a serious desire to make the world a better place, and have shuffled through HUNDREDS of potential approaches before settling on this project. I've partnered with or worked with at least 60 different types of companies/nonprofits trying to tackle the opportunity gap, graduation rates, mental health rates in USA. This company will tackle them all, will have a greater impact, and will have growing revenue & profit for years to come.

Last, I'm a life hacker at heart. Self-improvement and self-education are concepts I live by. Also, I know just enough code (html, css, have created 3 websites) to know how hard it is, how much work it requires, and that great websites take time.

Plan on applying to accelerators in next few weeks, if that appeals to you.

Ok. I really didn't care that the piratebay got blocked except for the legal precedent that created but as expected here comes the banning of every site remotely considered as "bad" by any corporate party.

Any LESS version?
It doesn't. Flashblock is one of the most popular Firefox extensions[1], and variants are available in other browsers. Even though it offers some protection against hidden Flash elements and supercookies, it would still be popular just to prevent autoplaying flash presentations.

The author of Flashblock even specifically mentions YouTube on the extension page[2]:

Youtube videos not blocked: This is because they are now increasingly HTML5 Videos. I plan to add HTML5 blocking in the next version. Meanwhile you can try out a experimental version at:
http://flashblock.mozdev.org/installation1.html#unstable

This indicates there is a demand for the autoplay blocking feature alone, regardless of the medium.

Is there a performance difference between using "div#container" and "#container"? When reading the css, I find it easier to be reminded that the element with the id container is a div element, but I guess its an additional check for the browser right?

I think OOCSS has a strong influence on this use of multiple classes instead of your example of nesting classes (which i would have done, too).

I'm not saying I totally agree, but OOCSS promotes the idea that your styles should be decoupled from your HTML structure. This makes CSS easier to maintain.

Hopefully cost, fluorinert is vary expensive. Also, with a low boiling point of 49c you should be able to avoid pumps as long as you don't mind the components sitting at 120f.
Yes sociological changes are probably necessary. I think it's a bit disingenious to discuss the "deluge of messages problem" without taking this into consideration. The "deluge" problem is more or less inherent in the current dating paradigm.

A lot of space is wasted by the bar at the top, the logo, then the placing of the title and finally the authors name. Changing those you would be able to have much more content on the screen and still have the nice large fonts.

Now personally I believe you could probably shrink the font size a little and still look good, but you still wouldn't get much content on the first page without fixing everything else I mentioned.
I am not an expert in the field, but a quick look through the product pages at 3M suggests that the important difference is the boiling point. Novec boils at 49 degrees C, so for cooling electronics the primary mode of heat transfer will be the phase change. Fluorinert seems to boil at higher temperatures, 80 and > 200 degrees for the two variants I looked at.

They seem to be in the same family of products and several of their physical properties are very similar, so maybe they're just variants.

Here's a link to a page which has both families:

It's a double edged sword. The unique point of difference benefits of BTC itself remain unchanged regardless of current market price, and furthermore, should early adopters dump all old coins onto the markets all at once, the lower price would only make it more affordable for newcomers to buy at discounted rates.

Recall that early adopters of questionable loyalty to BTC already had a chance, or two or three, to cash out at very favorable rates. Many did. The result is Bitcoins continue to drift into stronger and more loyal hands. Meaning, as time passes it grows less and less likely for there to be ANY event capable of destroying confidence in the markets. If you get into BTC at this point, you should know fully well what the risks are.

Qualifying selectors like that is always a bad idea because:

1) What if you ever need to use the selector on a different element?
2) A performance hit (though so slight it might as well not matter)
3) Increased specificity

Non-Profit Hopes To Get Kids Excited About Computer Coding
The gap is then derivative work. They basically take the core research done by NiH for free and refine it and demand in return a 20 years monopoly from the state. The biggest single actor in medical research is by a large factor NiH, paid through tax money.

Drug companies are the only market where this is happening. Why should they get this free research if we want the market to handle the research of medical innovation? You don't see the state doing the basic research of mobile phones and then giving it away to Samsung or apple. They can't just take some already taxed funded research and "refine", getting themselves a 20 years monopoly for the effort on the expensive of the public.

And what is the benefit for the public? They give their money away with tax money and get zero back in return? It is taxed paid research, and then the state gives out a additional 20 years enforced monopoly to the first one who do the last step and refine it. Maybe a bit ism'ish, but is this the core idea of capitalism; having the state pay for the core part of the medical industry without getting anything in return?

- According to wikipedia [0], fluorinert as used in the Cray was a single-phase coolant (no boiling). It needed fluid pumps and chilled water, at high energy cost; this phase-change solution avoids both.

- Wikipedia claims fluorinert has a very long atmospheric lifetime and high global-warming potential. [1] 3M claims this new fluid is destroyed by sunlight [2], and doesn't have the same problems.

Writing science fiction is one thing, pursuing your vision and getting it made into a reality is entirely another. But you're right - we are probably more in agreement than disagreement.
Great article, but not quite sure about the final bit of advice. Even if you gradually build your software in layers you might be faced with exponential complexity. If you are releasing early, then you also have the "legacy data" issue along with users who are just getting used to the interface. Change will be always met with resistance.

A harder but definitely more powerful approach is to build more isolated pieces of functionality with well defined interfaces. A conscious effort to minimize the feature interdependence definitely pays off in the long run. A team of moles is harder than an uncoordinated mob!
To be fair, I think the industries have got a lot better in recent years. I stopped pirating music when it became easier to buy it on my smart phone than torrent it and copy it across to an MP3 player. I haven't pirated any TV shows since iplayer / 4OD came out in the UK, and I think movies have gotten a lot better, but I don't watch them much.

Yes, it's pretty slow change, but given the size of the companies involved, and the risks of moving to a new business model, I think we have to give them some credit for coming as far as they have, and they show no signs of stopping.
Wow, they've definitely gone on a spam-killing spree recently. Following that scandal a few weeks back where someone had, uh, "inappropriate" downloads in their checked-in public .bash_history, I did a few searches and found insane amounts of spam in github pages.

There's your startup idea then. A high quality independent retailer for underground rock music. Boomkat for guitars.

Two problems:

1) Rock music is much more controlled by the big four labels. I checked the latest album from Lamb of God, the most fucked up metal band I could remember off the top of my head: they're on sony. On the other hand, Sunn O))) are on an independent label and they're pretty well known. Maybe lamb of god are more mainstream than I remember.

2) Rock music lacks electronic music's mainly nerd-based audience. While there are undoubtedly a lot of nerds in the metal scene, they lack the raver's inherent kinship with machines. Also, there isn't the same DJ culture, which is perhaps the most common reason why buyers of electronic music demand quality.

Ask HN : Mobile Application Development, Hire mobile developer or Outsource?
Hi all,

We are a small startup with a team of 4 developers. We are developing an application for realtime B2B communication.
Our service offering consist of web application and mobile application (Android and iOS).
Initially, we thought we would utilize PhoneGap to achieve our mobile application ambition. But the
PhoneGap application we have built, does not meet our expectations.

We realized that we don't have the experience or skill required for building mobile application in house.
We are at a cross road, where we need to decide either to hire an in-house mobile developer or outsource the mobile application.

I would like get opinions from fellow hacker news readers, on advantages and disadvantages of hiring in-house mobile developer
or outsourcing the mobile application.

Thank you
