Yes, I should have disabled Heathrow for now, as no tour operator flies from there. Try any other airport and there are literally thousands of results.

Data comes direct from the tour operators.

EDIT: have now disabled Heathrow until I add data for that airport.
EDIT:

wait, what? I'm convinced that thrust reverser would (in principle at least, construction details be damned) work with a propeller engine.

In my understanding, even if the air stream was accelerated rearwards at first, and only subsequently redirected frontward, it'd still create net force pointing frontward (decelerating one), without need for increased temperature nor extra mass from burned fuel. But I don't have solid physic background; somebody please correct me.

It may be easier to visualize it with a ducted fan. As used on some RC aircraft models, modeled after jet-engined crafts. I believe a thrust reverser would work in such a setup, minus friction and turbulent losses.
My bad for misinterpreting.

This is a classic example of how the physics community has been failing for the last 30 years.

First of all, there's an extreme focus on papers that have come out in the last 1.5 years, so that a lot of very interesting older work is invisible.

Secondly, physicists don't look outside the discipline, despite the fact that we often use inferior techniques. Back in the 1990's, Mark Newman and I were both working at Cornell and both of us were aware that the techniques physicists were using to evaluate power law distributions were bogus. Well, I was a timid grad student and, despite being one of the best physicists of his generation who already had written half of an excellent textbook and had a stellar research record, Mark was a postdoc who spent most of his two years in absolute anguish about how he was going to find his next job.

Mark wrote a paper about this ten years later, after physicists had published thousands of bogus papers using bogus statistics. It's a tragedy that neither Mark, myself or some other young turk didn't write it earlier -- and it wouldn't have been hard to do it all because it would mainly be a review paper of what was already in the statistics literature.

Great idea! It still needs to be tested of course for an accurate feedback, but the idea itself is really cool.

Only thing that I am concerned of is the lack of a policy and terms of use. Basically we are sending you our address and key and there is no legal policies or terms of use on the website concerning the use of these pictures, how they will be used and stored. I think this is the main concern I see.

Sounds like most people have an ad block extension (I couldn't see the ad either; had to use an alternative browser). Op (or whoever is advertising) paid for an Adwords ad. Unfortunately it's not original. People have done this before and the CPC can rack up although I'm sure they've set a low limit to avoid paying more than a few bucks per day just in case.

Keep in mind getting attention doesn't necessarily equate to success (nor does equal failing either). I guess it was worth the split test.
It also goes to show no scientific research (if performed rigorously and honestly) should ever be derided as being of little use. One wouldn't expect a graphics (!) algorithm to solve a (seemingly) physical problem.

Same as one wouldn't expect some obscure branch of algebra to give birth to modern asymmetric cryptography ;-)
I think a Ngnix/Lua full stack web app environment is a great idea. (In fact, I think there's a comment of mine with this very idea from about 8 months back.)

Here's how I see it. You have all these knobs you can twiddle with and see the results. Here's what happens when you turn the knobs:

make crack legal -----> crack-use increases a LOT

make crack cheaper -----> crack-use increases

increase mental health services -----> small/no effect

increase education ----> crack-use decreases moderately

So what have you gained by legalizing crack? In my opinion, you've shifted the beneficiary (the people at the top of the financial food chain) from being the dealers and their lawyers to being the government and their cronies.

The only half-decent proposal I've heard so far is to have the govt. purchase Colombia's supply of cocaine paste every year and destroy it. That would hugely drive up the street price and result in a net decrease in usage.

Yes. But the equipment on the back is radiating heat (roughly speaking) in every direction, as I understand it, so absent a reflector, the equipment would have a net zero effect on thrust. But because some of the heat is being reflected, it's contributing a non-zero amount of thrust.
Here is the most interesting snippet for me:

Facebook, for example, has been working to fashion its own variant of Android for smartphones. Executives at the social network are unhappy that Google gets to review Facebook's tweaks to Android, say two people who weren't comfortable being named talking about the business. Google has also tried to hold up the release of Verizon (VZ) Android devices that make use of Microsoft's (MSFT) rival Bing search engine, according to two people familiar with the discussions.

With Google being direct competitors with Facebook and Microsoft in the online space, they have a lot to gain by knowing their competitor's plans early/by being able to limit their influence.
He is assuming because he's the only one targetting "paul graham" as a keyword aka its the only ad up.
I realize that "food grade" stainless steel can mean many things, but I'm sure that if you contacted them, they would have no issues with giving you specifics on it. As for the interior material, it shouldn't ever be an issue unless you seriously abuse the shell, but they do list it as "100% edible". That's good enough for me. Lying on that point would probably mean jail time, enough of a negative incentive for me to trust them.
UoP is accredited by the same board which accredits University of Michigan. [http://www.phoenix.edu/about_us/accreditation.html] For whatever that is worth.

They have experienced difficulty regarding the rates at which students receiving Federal Financial Aid graduate - i.e. their issues are based on low graduation rates and not based on being a diploma mill.

Debate? What debate? MySpace was always a fad that was waiting for something better to come along. It follows the same fate as LiveJournal and Friendster. Facebook out-smarted, out-strategised, out-performed and out-visioned MySpace and its News Corp owner. The site sucked from a visual and experience perspective, and was completely unstable during its peak. Facebook's strategy of real names, real identity, real relationships and expanding out from colleges beat MySpace's strategy of letting sleazy 31 year olds chase 13 year olds--both using fake identities and whose profile page featured obnoxious animation and music. MySpace was a wild west of junk, but no actual "social networking" happening at huge scale. It was always superficial--a glorified hot or not.

MySpace is and always has been an entertainment portal littered with ads that were as obnoxious and their users' people pages. The user experience worsened following the News Corp buyout.

Facebook, OTOH, has always been about real identities and real relationships. Its design, compared to MySpace, made it feel like a tool instead of a toy. As a result, the content on Facebook has greater value and feels more legitimate. Everyone is familiar with the dating term "Facebook official". That's the power of Facebook. Facebook went beyond the primitive social networking elements of "moods" (status updates), walls and photo sharing. They became the de facto Identity Provider on the Internet.
Ask HN: How did Y Combinator get its name?
I've often wondered why the incubator Y Combinator is called "Y Combinator". Obviously it has something to do with the fixed point combinator (http://en.wikipedia.org/wiki/Fixed_point_combinator), but after reading that, I fail to see the connection to the Y Combinator program.

Maybe I'm missing something completely obvious. Can anyone fill me in?
That's not true, the Verizon Android phone that uses Microsoft's search engine has the market and gmail installed, it just doesn't have the sticker.

And the fact that it's open source is very relevant here as it implies minimum restrictions.
Does anyone know of a site that lists all countries who have either rejected or canceled this law?
A little out of my budget at the moment, but I can definitely see the potential market. My coffee was getting cold just as I was reading this.
+1 on that, commentary is excellent and concise. If you want a brief intro to concepts in distributed DBs this is it. Grab that coffee and turn up the speakers.
The iOS developer they quote extensively seems somewhat confused:

"And even if developers wanted to create such a “true tablet experience,” they’re hard-pressed to do it without the source code for Honeycomb, which Google is currently keeping a tight reign over. The big device manufacturers working on Honeycomb-powered hardware—like HTC, Motorola and Samsung—all have early access to the code, but only after licensing agreements were made with Google. Smaller developers don’t have this luxury."

Why would he think the source to Honeycomb is required to make an app scale to different screen sizes and resolutions?

I'm also wondering what the definition of "native" is in the headline.
DH6, actually, when you include the next sentence and the link.
Maybe Clay (http://tachyon.in/clay/) would interest you then? It does not explicitly says that it can be used for kernel development, but from the feature set it seems like it could.

Google Nexus S – The Gulfstream 6 of Android smartphones
I've decided to stop upvoting articles that have nothing to do with startups
Basically, reddit already exists, and an appropriate selection of subreddits can produce a nice selection of articles and decent discussion. HN is arguably higher quality, for now, but I don't have another good source for startup-related items. (Suggestions welcome.)

Just my personal preference, others may disagree and vote differently. It's just that lately it seems I'm sifting through an awful lot of general-interest articles, many of which I've already seen on reddit.

The more HN becomes a source for non-startup news, the more users we'll get who don't care about startups. Since HN doesn't have "subreddits," we'll end up with just another general news aggregator, gradually decreasing in quality like they all do.

I know that I've contributed to this, and I've decided to stop.

Pardon? Phong shading is a simplified model of results of a physical process -- light reflections off certain kinds of surfaces (metallic ones, IIRC). It's imprecise, it has its limitation etc. Contrast that with the very tiny, precisely measured acceleration of Pioneer spacecrafts. It is not very common to get good results from applying a coarse tool to a fine problem.
Nice song, really impressed! I hope he wins.
What does the 6% on the back end do to your valuation in later rounds? Assuming you do expect to take on more growth capital upon successful completion of YC. Not very much Coke left to enjoy after that...
Sure, it was mildly unprofessional to hold a mock funeral of a compteitors product.

On the other hand it seems to have been a private event where people partied, danced and generally enjoyed themselves after having launched a new product. They probably earned a little light hearted fun.
Thanks. From a technical perspective it does work, I have successfully copied a few working keys. There's zero infrastructure right now, if you use the app I'll send you an email by hand and cut the key myself. This is MVP!

Yep security is the biggest user concern, my plan for this is centered around keeping e-mail addresses and real addresses apart.

Ultimately though through my research on this I've discovered how trivial it is to get through most locks so it would just be way too much effort for a thief to use DittoKey.

The Innovation Mismatch: "Smart Capital" and Education Innovation - Joanne Weiss
My last experience with Photoshop was CS2, is that layer animation a feature in the desktop version?

Also tomlin mentions Dreamweaver, I think Adobe has the talent behind them to build a high quality IDE for web development.
Consider the amount of small web shops out there doing work for clients, designing sites in Photoshop, then turning straight to a different, non Adobe editor to actually develop these sites.

If Adobe came out with an editor to match TextMate, and a development environment targeted at these web shops and hobbyist, they'd make it so a web dev never has to leave Adobe products to take a rails app or wordpress theme or whatever. Surely there's a market for this?

Or maybe I'm giving Adobe too much credit.
Lots of things are "food safe" for incidental contact, but unwise to ingest. Lots of things are "edible" in small quantities, but you may not want to ingest them daily as they leak out of a container.

Lots of people are willing to lie to you in ways that could incur jail time if they perceive the risk of harm to be very low. I want to be able to asses those risks for myself.
It has to do with more than memory, right? At least if you want to come up with new things, whether directly in mathematics itself, or to use it creatively in some other field. The idea is that intelligence is partly indicated by how you can visualize things that cannot be seen, and often when someone cannot figure out a derivation of get at a result, it's more likely because they are not seeing the big picture.

I don't mean to say that people in general cannot be taught to see mathematics, it's just that they need good teachers and textbooks.

Edit: of course, all this comes only after having grasped the basic terminology at your fingertips.
I think a good web based design can make a lot of "native" application irrelevant. That, probably is what google wants anyway.

And probably dramatically more than have sold. Though some have questioned it I still think the Windows Phone Facebook App is a good indicator of how many phones have been sold.

It's true that you don't have to install that app to use Windows Phone 7. But Facebook is pretty integral to the Windows Phone 7 experience so the Facebook App's growth is a good indicator of how well Windows Phone 7 is doing. On January 26th there were 366,000 users. Today it's 549,042.

NASA is doing some strange things...

I've been using CLIPS as a library in expert systems for years. So, when NASA announced that they were set to auction off some patents related to expert systems, I started to wonder... What would happen if a government entity released innovative code under a BSD/MIT style license, but at some point decided to patent some key potential use cases? If the patents then found their way into a corporation, early adopters might be left in an awkward position. That is somewhat obliquely worded, but you get the gist.

So, I'd say that if NASA wants 'to make openness the default' they need to start with their IP policies.

I was hopping that this would lead to us sending out plenty of extra-solar-system probes so we could perform more wacky measurements like the pioneer ones.

http://www.wired.com/wiredscience/2011/03/vanishing-dimensio...

I think the only qualitative way to guarantee research progress is through the expansion of the things we can sense/ perceive. For example, if we want to understand space better, I don't think another near earth telescope is the answer, but rather several that float at the edge of our solar system.

I am also excited about IPN- the Interplanetary Internet by Tim Burners Lee. So that there is a standard way for these crafts to communicate and relay messages as they get really far out.

Perhaps the intersection of people who think "it's just a big phone and I really want a laptop" and people who develop for android is quite high.

Still - given Honeycomb is being touted as the "ipad killer", and ignoring the silliness of that concept, it is surprising that developers aren't seeing the xoom as a good way of getting ready for the flood of honeycomb devices that is apparently coming. It's hard to work out from the various trolling headlines about how iOs or Android has "won" something or other - but doesn't Android have quite a healthy developer base? are they making money?
This, to me, is the problem. I didn't expect Windows Phone 7 to win over Android or iPhone developers. But if you are a Microsoft developer it's hard to start developing for Android or the iPhone. Because you have to use a different language, different tools, a different environment, etc...

Given that I expected Microsoft developers to jump at Windows Phone 7 because it was an easy way for them to translate their skills to a mobile platform. But as someone who knows a lot of MS developers they all seem pretty apathetic. More than anything else that makes me doubt the platform's long term future.
AV software is written to pass the tests of AV software reviewers. This is subtly but importantly different from "written to accurately detect and block malware"; in particular, it's extremely difficult for a reviewer to test an AV's ability to block completely novel malware (unless they're a malware author themselves or connected with someone who is). So, people tend to set the AV software to scanning a folder full of known samples and judging the software on how many it detected (this is a nice, easy metric: you can make bar graphs out of it!) - in this situation, if chucking in a signature for C:\windows\SL gives you an easy extra malware detection at the cost of a false positive (that no reviewer's going to spot anyway), it's a no brainer.
Well first of all it's "Do No Evil", and frankly I don't think you can compare the two. Where Microsoft 10 years ago did everything they could to force you to use their products (bundling the browser, exclusivity with all consumer computer OEMs, etc), Google has made really good products that people want to use. I'm not forced to use Gmail, or Google Talk, or Documents, but I choose to because it's the best out there.

I'm not saying Google isn't Evil, there's definitely some questionable things they've done as of late, but to try to compare them now to when MS was at its "evil" peak is disingenuous. Google built things people want to use. Microsoft built things so that you had to use them.
