There are some things that are in the private apis that make dealing with certain problems a 100 times easier. Sometimes you just want the gui to force a rotation to a certain orientation at some point of the app. Other public api's such as rotate top bar are more crufty, and don't work 100% of the time, or require fragile workaround where you do all the rotation manually yourself because the public apis are fragile, while the one-line simple private api would of done the trick.
Interesting to know how fruitful these measures are.
They are not cheap, but if they do not bring justifiable change in security - that is another way to distract people from real problems.

There are several applications for OSX which take a website and make it appear more like a native app.

The Windows Start Bar, the OSX dock, the OSX dashboard are all much nicer methods for managing apps than how ChromeOS appears to do it, and they've all been around for years. Google should have come up with something better than these for ChromeOS, not worse.

Lots of people are using Lanyrd for group meetings, social events, and all sorts of things that aren't conferences (eg http://lanyrd.com/2010/brightonpy-october/skgp/ ).

I do think that overlapping and tiled windows are very useful for a 12" screen. They're certainly highly useful and desirable on my 13" Macbook screen.
The retain parameter is a secondary stack for temporarily storing things from the data stack. It can be manipulated through the `r>` and `>r` words. The former puts the top of the data stack at the top of the retain, and one does the opposite. The `dip` word isn't a primitive in this implementation, but instead is defined as `swap >r call r>`, which saves the value underneath the top value of the stack (which is expected to be a quotation), calls the quotation, and then restores the retained value to the top of the data stack.
I reduce window width to give a comfortable column with where the document allows, then use scrolling as a place-marker. I'm a line or two down from the top of what's displayed.

Note to everyone here: the interesting issue is CVE-2010-4258 (write a NULL to arbitrary memory on OOPS). The other two issues have been deliberately chosen to be exotic and hard to exploit, but

* However, the important issue, CVE-2010-4258, affects everyone, and it would
* be trivial to find an unpatched DoS under KERNEL_DS and write a slightly

[EDIT: this was also pointed out by bdonlan, http://news.ycombinator.com/item?id=1981738]
Well I'm wondering what else it could possibly be. This was all formulated with the name kept in mind as well. Google +1. If that is correct then everything is about +1ing what you find on the web. Or this could just be an elegant hoax. But given that it is Tech crunch they are pretty much the best at grabbing leaks.

By the way, just to point out one thing, I'm not entirely sure either task, FB iterating into full on search and Google entering the social market is simpler than the other. But yes Google already has its very firm foothold in search. But then again you might not be considering that Bing could easily partner up with FB is the past trends are anything to go by. In which case Google should be doing there best to come up with something special.

And question. Why exactly would it be a poor product choice? I'm basing my thinking on the design of rockmelt, it has the share button and the friend edges which basically let you watch your twitter feeds and chat with fb friends from the browser. I hid the friend edges when demoing the software, wanted to save it for the final blow. I tell you I could have left with the share button and they would have thought it was a pretty neat idea.

That is obviously not a majority vote but it might be an indicator that the share button is cooler than we think. Although yes. With all the hype that was surrounding Google Me... This does feel like a kick in the head.
I agree with the general principle-- rudeness and incivility should be avoided, and treated with a "broken windows" policy-- but in this case, I fail to see the rudeness in swombat's response.

You asked Who's been calling to kidnap his son?, and swombat pointed out that the article you were responding to quoted Assange as saying An American blogger has called for my 20-year-old son, here in Australia, to be kidnapped and harmed for no other reason than to get at me.

In other words, the answer to your question truly was in TFA, and swombat not only pointed that out to you, he actually quoted the relevant passage. That warrants an upvote in my view.

His distance based near neighbor search algorithm is good but as I noted in an email to him it performs at worst in O(|T|) distance computations where |T| is the size of his text corpus. While this is fine, you can do better if you use distance based indexing methods. Such methods will give you O(log_{k}(|T|)) distance computations to find the nearest neighbor. Where the k depends on the index structure used. For the simplest structures, such as a vp-tree or gh-tree, k is 2. However, for more advanced structures such as Bozkaya and M. Ozsoyoglu's MVP Tree or Sergey Brin's (yes that Brin) GNAT, k can be much higher.
It would be cool if you could tell us more about the structure behind the website.
Rockmelt is a browser; it is apathetic which social site you want to use. That you are using one is a plus for them :)

For Google acting as a clearing house for social data is fine.. but even better, have your own social graph which, linked with search data is incredibly valuable to them.

Google have wanted their own social graph for a long time now - I don't think they would drop that lightly.

Bear in mind that I have not one large corpus but ~8m short formulae. The filtering stage removes most of these in O(L log N + KL) time, where K is the number of results which match one or more fragments, N is the number of formulae and L is the maximum formula length. In practice K is about 3x the actual result set. So yes, in the worst case this is O(T) but in practice the performance is very good.

I've used a variety of spatial index trees in previous versions but this method improved perfomance by 80-100x on typical input. I think the main problem is that the equation space has an incredibly high dimension and the vast majority of pairs of formulae have no elements in common so most comparisons give you little information.

This is pretty much the opposite of my opinions. Android documentation is awful. Mostly it isn't there at all. Many times I found that it was in fact wrong. iOS documentation is really good. Garbage collection on mobile devices means you get UI stutter because GC kicks in when you don't want it which means your app feels less slick. Xcode 4 is pretty good, but yeah Xcode 3… However Eclipse is slow, clunky and buggy.

Also I have found myself doing weeks worth of hacks on Android AND iOS. Both are large frameworks, and ultimately they don't have abstractions for everything you may want to do.

The article reads like the guy hasn't really got his feet wet with Android development yet. He's yet to be bitten by not handling the activity lifecycle correctly for instance. The real edge cases of that didn't start materialising until we had 20,000 beta testers.

Good experimental results! The high dimensionality (or non dimensionality) of the space can definitely hurt performance of spatial trees such as R-Trees, however for distance trees what really kills you is the the metric to compute the distance. There can be a couple of problems with it: 1) if it takes a long time to compute that will obviously hurt you, 2) if the variance is low or if some distances are meaningless the tree will be mishapped.

I was thinking as I was going over the article again that you could represent you formulae as trees instead of strings. This might yield more accurate/interesting distances. I recently used the PQ-gram distance[1] to compare subsets of ASTs with great success. PQ-gram is a really fast approximation of tree edit distance. I also tried using exact edit distance with the Zhang-Shasha algorithm[2], but in general the PQ-gram was so much faster the greater accuracy of ZSS didn't matter.

I subscribe to the idea that the eventual evolution of social networks is "openness" (eg, fb will either be killed by an open 'social protocol' or or be forced to open itself).

Google's strategy shouldn't be another social network, or a closed social layer atop their current properties. They should invest heavily in the technologies that would kill fb and open them up, completely - opensocial, diaspora, etc.

Yeah, you're right. Call it slapping an index on the column holding actual data. My bad.

(The reason that primary keys tend to be auto-indexed is simple: to verify uniqueness, you need to check whether the primary key of the record being inserted is already in any record. Doing this without indices would be painfully slow.)

Because the people who 'do care' as you put it, try to 'improve' by imposing a cost on others, namely by polluting every discussion to the point where the actual points get snowed under and this he/she non-issue takes over as the main focus (case in point: this discussion).

It's like Jehova's witnesses or other nutcase religious people: 'oh we're not harming anyone!' - not putting a gun to my head, no, but still ringing my door bell, proposing legislation based around your idiotic beliefs, etc. Get lost with your 'trying to save my soul' and if you really can't contain your beliefs and have to somehow involve others, at least pick people who have expressed an interest (i.e., post on alt.philosophy.feminism or whatever) instead of always imposing your 'debate' on everybody.

I could see that data being nice to review if you were writing a private diary/journal for your own future consumption.

Other than that, the concept seems pretty flawed - git is useful when you manually commit at the end of a chunk of writing, and again after an edit/change.

> the public is being brainwashed into thinking that science is more important than creative endeavors

1. They aren't.

2. Science is a creative endeavour.

3. If people believe that science is more important than creative endeavours then perhaps it's because science has brought us machines that allow us to fly, little magic boxes you can carry in your pocket that let you talk to someone thousands of miles away, the ability to have sex with a reasonable confidence of not making babies, other little pocket-sized boxes that will capture and replay highly realistic moving pictures, large bridges that don't fall down, people walking on the fucking moon, devices that can see into your body and tell whether you have cancer, other devices that can kill the cancer inside your body if so, things cheap enough for almost everyone to own that will let you travel five times faster than a fast runner for long distances, etc., etc., etc. What you call "creative endeavours" have produced wonderful things too, but if I had to choose between Hamlet and antibiotics I'll go for the millions of lives saved.

> Why is nature more interesting than the human imagination?

More interesting? Well, that's a separate question. To many people it isn't. Those to whom it is have all sorts of different reasons. One would be that nature has a lot more in it than the human imagination. ("There are more things in heaven and earth, Horatio, than are dreamt of in your philosophy", as one of those creative types made one of his characters say -- though he meant something else.) Another would be that human imagination is limited by, well, human imagination, whereas nature is full of things that no one could have guessed. The moon is kept in its orbit by the same thing that makes an apple fall? Space and time are the same thing, and it's all curved? Light travels from A to B by taking every possible path from A to B and interfering with itself? These things, to someone who's thought about them enough to know what they mean, are astonishing.

> playing a lottery that they will discover something huge

I think you may have bought into the common misconception that all scientific progress is the result of occasional geniuses making huge leaps by the sheer power of their enormous brains. It doesn't really work that way. The advance of science is a collective endeavour; even if you never discover anything huge, you're contributing to it.

(And: why would someone become an artist, musician or author, essentially playing a lottery that they will create something wonderful even though such creations are extremely rare? Most books are unpublishably bad. Most published books are pretty weak. Even of the best published, most will probably be almost completely forgotten in ten years. -- And, again, there's nothing wrong with that: even a not-so-great artistic work enriches the world. And so it is with science.)
