Well it only matters if it's going to get loaded a bazillion times. I mean, if you're focusing on something that's really good at a small domain, than I don't think you have anything to worry about. People keep optimizing crazily based on the assumption that it's going to be everywhere, which seems to be a bit overly optimistic.

OK, I see your point. But still the question remains if FB could convince popular websites to try Ads with them. It would definitely be an interesting to see the results.
Right, but brain capability is not a one dimensional quantity, and measurements of it are time-varying and noisy. This suggests that one shouldn't jump to conclusions before careful measurement, and that it is not trivial to compare measurements from different people along just one axis.

Cold Calling your Way to Singapore

> But not much effort has gone into making these solutions user friendly and giving them the marketing push of something like this venture.

This is the key thing. The desktop app I'm imaging is user friendly, and probably at least somewhat pretty. I think the main technical issue is probably the fact that most people are NATed by their routers, so peer to peer is tricky, but I think with uPnP, you could get around that.

I was originally thinking of this as an open source app, but I suppose one could go the paid app route.

Good question. Does the "defense spending" category include the trillion dollar wars in Iraq and Afghanistan? George W. Bush's administration conveniently swept the wars' costs into a "supplemental" budget separate from the DoD budget.

As someone who has done research in the field, did you read the Gizmodo review of Siri?

http://gizmodo.com/5864293/siri-is-apples-broken-promise

The set of "knowledge graph" problems which is not, in fact, AI-complete, strikes me as much smaller than most doing research in the field would like us to think.

I hope you won't try to argue that "book me a room" etc. isn't AI-complete. There's an uncanny valley there, and it's deep. You can use Siri for lots of trivial tasks in which bizarre failures are hilarious rather than disastrous, but booking hotel rooms isn't in that set. She can be the best secretary in the world 9 times out of 10 or even 99 out of a 100, but the other times she's an insane robot who wouldn't at all mind sending you to Cebu to get kidnapped by the MILF...

> you probably aren't the kind of business they're looking for.

Sure, but isn't this the problem?

Assume you have a revenue-generating business making 250k in year two. In my opinion, this startup should be valued at considerably more than 10x revenue. But that sort of valuation is hard to get, and likely impossible if the founder has to jump through hoops simply to get introductions.

What will these companies do? They'll focus on growth and avoid raising capital. Because once you break about a million capital becomes really easy to raise, and you can get money on far better terms than any VCs will offer. So there's an adverse selection problem here that effectively concentrates investment in high-risk businesses, since as soon as companies become self-sustainable pursuing funding for growth is usually less preferable to chasing down outside money.
A big part of our problems are the calculations that were used to justify Social Security and Medicare (over half our budget). Neither program was built to last more than two generations. The politicians that created them didn't care about that (FDR and LBJ), in typical intentional short-sightedness. Both programs were designed to be flush early so they could be plundered. Instead of having trillions sitting in a sovereign fund earning interest, we have a blackhole of entitlement liabilities.

In other words, the biggest problem with our social systems is theft. The money was used over two generations to buy votes.

edit: it's interesting to try to calculate it roughly, but, it seems fair to estimate that the politicians have spent an inflation adjusted $30+ trillion beyond their means over the last 70 years ($16 trillion public debt, plus the money that should have been put aside and earning interest from SS and Medicare etc).

Ask HN: Data Scientist compensations
Data Scientist as a position is quite new and their roles are pretty much evolving still. In such a case, it is a little difficult to assess a salary offer for the position mainly since there are a few data points to compare with.

Any thoughts/inputs/answers on what range is a reasonable compensation for an entry level data scientist at an internet company based in the Silicon Valley ?
Gas is subsidized by wars in the US. If you keep that in mind, the value that they get from their money is not that low.

Thanks, I was confused too :D
No, a lot of defense spending is not hidden under health.

$850x billion is spent on the military. That has doubled since the mid 1990s, and so has everything else roughly.

Now, if you want to consider whether the CIA is an arm of the military, that's a fair issue. If you want to look into the drug trade and how much money the US Government makes from that, that's another fair issue. Also, should the NSA be considered a military wing, because it has a $80 billion budget all by itself.... If you count those types of police state entities, then the military spending is another 5% of the budget.
Should be titled '3 years of government spending in one graph' as it seems to completely fail in putting the figures into context by skipping intervening years, so we have no idea from this whether this is representative, or cherry picked for effect.
> If the money is in bank accounts, then it is contributing to the economy.

It is, but only in the most limited fashion. Money sitting in bank accounts is doing very little to improve unemployment. Buying physical goods would be much better for that.

> One of the worst economic problems of recent years has actually been the lack of money just sitting in reserve to give the banks stability.

In a way, that's true although I wouldn't frame it that way. The banks could make loans and then sell those loans as investments -- they didn't need any money on hand for that. Increasing deposits, for example, wouldn't change anything.
Interesting comparison, but I find it hard to relate to at all simply due to the sheer amount of words you need to learn in a real foreign language to achieve fluency. Seems much more daunting to me...but I guess my glasses are tinted.
Ask HN: Pure Math Problem
I'm reading A Course of Pure Mathematics, by
G. H. (Godfrey Harold) Hardy – available free on Gutenberg. In the first chapter he presents the following problem (on rational numbers):

If λ, m, and n are positive rational numbers, and m > n, then λ(m^2 − n^2), 2λmn, and λ(m^2 + n^2) are positive rational numbers. Hence show how to determine any number of right-angled triangles the lengths of all of whose sides are rational.

I'm not asking the solution, but I'm not sure what he means by "any number of right-angled triangles"
It looks like it's just taking the place of having to attach an event to the radio button, doing a lookup on the sibling #find_me element and manipulating it's style via JS.

"past failure ... the electric car industry is one example."

Actually, electric cars were popular before gas cars were.

This is an area where hackers can really make an impact.

We tend to forget how necessary movement and control is for our daily routines. There are people out there who even lack the ability to turn on|off the TV. A little hacking with an arduino, and some buttons will make it possible for them.

In hackaday.com, one consistently sees hacks that are for the disabled. Special game controllers for people missing an arm, or some other limb are popular and simple to re-create.

I do have a personal anecdote.

I was once buying some resistors on the local radio shack. While I looked in the mess of tiny plastic bags, another person started to browse for electronic bits. I started to talk to him, and found out he was a doctor. His work was in dealing with disabled people. He had learned how to work with embedded electronics and fiber composites in order to build prosthetic limbs for impoverished patients.

Just amazing.
Sad that this is now considered a "hack".

Not true. A right wing lower taxes point of view 55 years ago was to drop the top taxes on rich people from over 90% to about 70%. A right wing lower taxes point of view now is to drop taxes on rich people from 15% to 10%. And anyone who thinks that having more tax brackets with much higher top tax rates is viewed as a radical.
I honestly don't care. Just pay me.
The author makes an interesting point; however, he seems to make the same assumptions that he is actively protesting. If smart people do X, then would not doing X mean people are not smart?

This generalization that can be inferred from the article--as well as demonstrated in this comment section--seems to fall into this same trap.

As a reader of "The Seven Habits of Highly Effective People", I think there is a better way to go about this. Rather than "smart people do X [therefore if you do not do X, you are not smart]"; it should be: people do X, which is smarter than doing Y.

People can change. If they have a consistent ability to do stupid things, it just means they are acting in poor judgement and possibly could use help. If they fail to accept help, or are too headstrong/temperamental/can-never-be-wrong then it just means that their behavior and mindset should change [in order to be more productive].

Although, I would sometimes choose a less-intelligent person that is of no fault of their own, than a willingly ignorant person who should know better, but does not act it.

> Did I just end that sentence with a preposition? Need more practice.

For me, grammar is the farthest thing from the real issue. What I find makes it difficult to communicate are situations when the writer/speaker is producing without the understanding that the reader has no fucking clue (or limited understanding of) what they are discussing.

Inevitably what I read or hear in terms of "specs" or "user stories" has an entirely different meaning to the writer/speaker than to the reader. The writer/speaker generally has at least some domain knowledge and often assumes such knowledge that should not be expected of the reader/listener.

Sort of ironic but pretending your someone else "really well" could qualify you as both perhaps insane (under some definitions) and as a really good writer/speaker. The critical point for me is the age old adage "know your audience".
Google does encourage marking up pages with Microdata, Microformats and RDFa. http://support.google.com/webmasters/bin/answer.py?hl=en&... Google publishes tools to help with these.

The world would be a much better place, IMO, if everyone ever knew about this cognitive bias and was reminded of it periodically.
Fiscally I think you're correct as people's views are heavily affected by economic cycles. As the current young generation gets old we'll remember how the recession affected us as we entered the workforce. We'll also have to deal with the debt by then resulting in a more fiscally conservative electorate than we have now.

Socially, we've been consistently getting more and more liberal since the country was founded. Gay marriage is the latest example. Despite North Carolina, polls have shown that support for gay marriage is very much generational.

BANNED FROM THE USA: Billionaire Facebook Cofounder Could Be Barred From America
Interesting choice including Republican and Democrat, there.

I don't think they're stupid, but if someone identifies themselves as "a Republican" or "a Democrat", as opposed to "the Republican party best fits my views", or "I'm a registered Democrat", I pretty much write off any chance of having a decent political discussion with them.

A large segment of the population follows politics the way they follow football, except without even watching the games, just the commentary and opinion pieces afterwards.

Smart people also triage their time so as to not waste it going down likely unproductive avenues.

But it's just a numbers game; there are invariably going to be people a level above me intellectually who this will filter out. But I can live with that.
Why Doesn't Amazon's Price Sort Work?

I had no idea what ~ did after reading that post. Should have simply stated that:

"The tilde (~) selector lets you target a sibling element. That is, an element that shares the same parent"

Could then explain how it's different than the + selector.

"This differs from the + selector which will only find an adjacent sibling (immediately following)."

I'd consider comparing it to the child and descendant selector, if I could word it properly. This is what I have which I'm not happy with:

"In some ways, the differences between + and ~ are like the differences between the child selector (>) and the descendant selector (a space), in that #header > a will only a elements directly under #header, while header a will target all a elements under #header, regardless of depth.
I am not sure exactly at what level you wish there would be more spending on public transportation, but spending money in that field could be a big waste of cash in the US. It's way too big and too decentralized. It makes sense in some countries (in Japan, for example, all cities are on the coast because nobody builds stuff in the mountains, so it's easy to connect the dots), but public transportation would not work well outside of a few big cities in North America.

Even in France, the bullet trains lines cost way too much versus their planned profits. Some will not be profitable for another 20-30 years! And that's assuming that, by then, it's still the best way to get from A to B. It's all about getting votes in the end, it does not make economic sense at all.
I'd be really interested to see how your set-up works. Would it be possible for you to share your files/code and a short description of how you implemented your set-up? I am happy for you to remove/sanitize sensitive details relating to your portfolio. However, I would love to understand how I can develop a solution like this for myself.

Thank you for your help.

Perl Gems: A Quick Look at the Blekko Search API
Some time ago I used both Flot and Google Charts to build a dashboard. Each of them have it's own strengths. I believe that flotr2 is not so different than flot to what I've seen.

By the time I was woking on this project Google Charts was fragmented into 2 different libraries, Google Image charts and Google Visualization API.

My project was to draw a dashboard with multiple charts and connect them to data sources that collected the charts data on the backend. So every time you loaded the dashboard it fired multiple AJAX calls one for each chart's data.

Flot was very easy to work with, the interface to load data is simple and makes sense. It offered good options to customize charts. It offered Mixed charts where you could have lines and bars on the same chart. That was the only reason I brought flot to the mix, there was no way to draw charts using bars and lines on Google Charts back then.

Google Charts on the other hand was a little bit harder to work with. The interface to input data is less obvious and has some strange decisions. Important to notice that Google Charts also defines a protocol to load data into charts, the protocol was called "wire protocol" back then but was renamed to "Chart Tools Datasource Protocol"[1] currently on version 0.6. Sometimes the chart design was inconsistent and that was apparent when you had a bunch of different chart types on the same page. The Geo charts also had a weird behavior, different from most other charts, possibly because they were rendered using flash. The protocol Google establishes for chart data is hard to get started but once you integrate with it is very easy to change the visualization and creates good structure.

Google Charts got a big update a couple weeks ago, the previous version are being deprecated and all charts are now rendered using HTML5 techniques, most of the time SVG. The protocol also got a big update and fixed a lot of bugs that made my life somewhat miserable weeks ago. Now it also supports mixed charts (bars and lines), so I don't need flot anymore.

I'm in the process of creating another dashboard now, and I've been using Google Charts only this time.

My advice is that if you're planning to draw only a couple of charts and flotr2 does the work go with it. It's easier to work with and lighter.

If you're building something that depends on charts a lot go with Google Charts. The protocol will come handy and it has some helpers to connect to backend data sources and Google Spreadsheets built-in.

If you need to create a product that relies on the charting library too much you probably want to support more than one charting library and possibly have the option to switch the library on the fly. The deprecation of the previous Charting library. The deprecation policy for Google Charts may be a little frightening[2].
