Thanks for making me discover owncloud! The only sad thing is that it uses server-side encryption, which I don't trust even if I own the server :(

However, through the power and sheer awesomeness of open source, I might try to get my hands dirty at implementing client-side encryption sometime. The rest of the software looks perfect and I have a couple Linux boxes just begging to be used :)
I'd be concerned that it would be relatively easy for someone to bribe a government/police/datacenter official to physically get at the servers located in a developing country that held my data.
In this case they were photos the guy took himself. It's hard to see how they would have got onto a blacklist unless Microsoft put them there.

The problem is, once an athlete begins taking performance enhancers, every other athlete in the sport has to as well, to stay competitive. Then suddenly those in the minor leagues/college are not competitive to move to the majors, so they start taking performance enhancers. But then high schoolers aren't competitive to move up, so high schoolers have to take performance enhancers.

This wouldn't necessarily be a bad thing if we had performance enhancing drugs that had no side effects. Unfortunately we don't. You seem sure that performance enhancers are harmless, but they most certainly are not.
Thanks again! You restore my faith that it is possible to have a reasonable conversation around here.

This leads me to a question: Do mathematicians actually try to analyze primes by looking at a function that is created by combining a set of sine waves where there is one sine wave for each integer, on order to form a sieve out of the sine waves? E.g., creating a function that crosses zero only at each composite, or some such? Or is this visualization only suggestive of a broad approach?

The paper cited by the visualization is clearly attempting to do what I just described, but it appears to be the work of an amateur, and I don't read Spanish, so I can't really tell if this approach is on sound footing. I tried to Google around looking for this approach referenced in something more authoritative, but couldn't find any. I did find plenty of references to trying to analyze the function that you get from subtracting x/ln(x) from the prime staircase, using Fourier transforms and the like. But I can't see a direct connection between these approaches, other than the general inspiration of trying to break the problem down into a combination of sine waves. On the other hand, I'm well aware that a lot of identities in math are not readily obvious!
Ant, congrats on the project. I believe it is a great tool at this moment it is very far from being a startup or business. We, Turkish developers, are good at developing such tools but converting them to profitable products. Don't do any categorization/tagging feature. It won't get you 20x users. It won't make you win an award from ACM or so.
Focus on the idea/problem and make really sure that you are solving an actual problem. In this case, is losing Facebook videos I watched really a problem that bugs many people? How frequently does that happen? Your product should fit to the market very well. Otherwise, it is an hobby project (which I used to have so many of them).

Ask HN:A Google presentation slides JS library?
A couple of weeks back someone posted the google presentation slide js library. I tried googling it back it I can only find a basic which does not have the features that was shown in the demo link that was posted here. Features like code focus. Does anyone have the link for it? I would have saved the topic if I could, but Upvoting a story does not save a story for me sadly. I basically have to comment on every post that I like just so I can view my comment to check the story for a later time.
While this (and other things mentioned like EncFS) is a solution, it integrates badly with user experience. I cannot access my data via web interface or smartphone app and I value this very much.

It is a bit complicated, but you _can_ create smartphone application and web interface for the data encrypted on a server.
I don't think limiting your reading to The Atlantic and Economist is a good idea. I would advise reading fewer stories from a wider selection of sources then applying point 6. "Why" to the text. Why was the story written? Why was the story published? Why in this source and not others? You want to dig beneath the surface to uncover the agenda. There is always an agenda.

Understanding how others try to steer your thinking and actions is as important to a renaissance man as the ability to sketch the valves of the heart or conceive a flying machine inspired by nature.

I've actually had this happen to me a few months ago; I tried to sign in and my account was locked due to some private pictures I had stored. I decided to just wait out the the "grace period" they gave me. When I checked back a few weeks later, my account was left unchanged. I hadn't even contacted support, so I'm curious as to why my situation was any different. As far as I can tell, all charges were dropped.

I'd argue that it's not completely offline because it requires time-sync, depending on the precision of the client. That assumes the validator is online and can re-sync at any time.

Well, it uses a 30 second window, so it can cope with small drifts; as long as the phone's RTC isn't broken, you should rarely need to re-sync.

I use it with a J2ME application on a Nokia S60 without an internet plan and it works fine.

EC2 is cheaper than people like to claim

How often do we have to repeat this argument here on HN.

When running 24/7 then EC2 instances are 2-3x more expensive than the cheapest equivalent rent-server options and orders of magnitude more expensive than the physical hardware if you buy it.

The numbers have been recited countless times, I'm not digging them up yet again.

So, no, EC2 is not cost effective for steady loads at the mid-range. EC2 shines at the very low and the very high end and in specific workloads, i.e. it shines when the benefits can be quantified to an amount greater than the price difference.
"I have started to hear more stories about folks switching back to Firefox because a lot of their issues with the browser have been fixed"

There was a time, some number of releases ago (a year ago?) when FF's memory problems became too much for me, and I used Chrome(ium). I never liked it, personal preference.

Finally some time within that last year FF became acceptable again, then more than acceptable, and I came back. I have not noticed my browser for months now, which is all I ask of any program: I don't want to see or notice the program, only what I'm working on with it. Don't make me notice you, it's distracting.

Although I use Firefox, Firefox is not actually my browser. Firefox plus the particular addons I install is my browser. To me they are very different things.
My thoughts exactly. I don't use FB or Twitter or iMessage. So what good are all those "amazing" features to me?

"I actually love single-walled carbon nanotubes; they're like the superheroes of material science." I feel the same way. This kid is genuinely excited and interested which, is extraordinary. I love seeing youngsters getting excited about science.

Unfortunately, this blog post and the one it claims as a source [1] are rather fluffy on details. Justin organized this information and presentation for the Intel Science and Engineering Fair (ISEF) [2]. More details about the process he discovered can be found on the ISEF 2012 profile page [3] and for those who don't want to follow the trail, I've reproduced it here:

"Pancreatic cancer is a devastating disease with a five-year survival rate of 5.5%. One reason for this is the lack of a rapid, sensitive, inexpensive screening method. A novel paper sensor is described that simply, rapidly and inexpensively screens for pancreatic cancer. Mia Paca cells overexpressing mesothelin, a biomarker for pancreatic cancer, were cultured; mesothelin was isolated, concentrated and quantified with ELISA. After optimization with the Western Blot assay, the antibody to human mesothelin was dispersed with single walled carbon nanotubes. This dispersion was used to dip-coat strips of filter paper, rendering the paper conductive. Optimal layering was determined using a scanning electron microscope. Cell media spiked with varying amounts of mesothelin was applied to the paper biosensor. Change in electrical potential was measured before and after application and a dose-response curve was constructed with an R2 value of 99.92%. In vivo tests on human blood serum obtained from healthy people and patients with chronic pancreatitis, PanIn, pancreatic cancer revealed the same trends.. The sensor’s limit of detection was found to be 0.156 ng/mL, satisfying the limit of 10 ng/mL, the level considered an overexpression of mesothelin consistent with pancreatic cancer. The sensor costs $3.00; 10 tests can be performed per strip. A test takes 5 minutes and is 168 times faster, 26,667 times less expensive, and 400 times more sensitive than ELISA, 25% to 50% more accurate than the CA10-9 test and is a sensitive, accurate, inexpensive, and rapid screening tool to detect mesothelin, a biomarker for pancreatic cancer."

I'm by no means suggesting that citizen/consumer activism short of violence is useless. In the past the 'Yes Men' and other groups have dragged the 'forgotten' issue of the Bhopal incident back into the news, generated significant bad PR and gotten politicians attention. I just fail to see the value of this particular stunt. Have people learned anything new? I doubt it. Are people writing to their elected officials, organizing petitions or boycotts? Not that I see. It's actionless preaching to the choir - "oil companies are evil" etc.
The firefox tab scroll feature is probably the feature I hate the most, in any browser (yes, you can disable it - but bad defaults stink and you can't just go around and change the settings in everyones browser).

I much prefer the Firefox tab scroll feature, compared to Chrome's way of handling tabs. The handy "show all tabs" dropdown is nice as well. Between the two, I find managing large numbers of tabs to be easier and less painful in FF than in Chrome.

YMMV.
>Ever since the middle of season one where he was given the out (the rich couple offered to pay) I just couldn't stand him.

Ah, you should have kept watching as this was explained. I'm going to go ahead and spoil this one for you: the reason Walt wouldn't take that money was because in his view it was already his money. In Walt's opinion (and maybe he's right) those rich people built a company completely on his ideas and cut him out. Instead of struggling with two dead-end jobs trying to provide for a family he should be driving expensive cars, have a huge house, library, etc. They are living the life that is, by rights, his and he sure as hell isn't going to beg for a small portion of that stolen money back.

IMO the show is about a good man being changed by life situations into an evil person and watching how he deals with it. The twist is; Walt had already changed before the first episode. He was once a good, moral, optimistic person but the betrayal by his brother, the years of slogging away in public school, having to get on his knees and scrub rich kids cars had changed him.

He became an evil, violent killer. But he was sharing a body with "ghost Walt": that good man from before. Ghost Walt wouldn't accept what Walt has become. This is basically how the whole series plays out. In the beginning Walt thinks he's completely pure and only does bad when he convinces himself to. For example when he makes a list of why he needs to kill crazy 8. After he had decided not to he had to check one more thing and finally had the evidence real Walt was looking for all along. Ghost Walt was angry that he found it. As the show progresses this dynamic flips: Walt kills and then fills in the justifications later ("You made me do this, this is on your head").

I'm half way through season 4 but I'm expecting Ghost Walt to eventually disappear and Walt to finally embrace what he is as Ghost Walt is now endangering his life.

Another extremely interesting change is Walt's wife! I'm really wondering how far she will go because I think she was genuinely good when we met her and I suspect she still believes she is.

EDIT:

Also, about taking the money from the rich people, it should be mentioned: if he had taken that money what would it accomplish? So he can continue to live as a failure, working two dead end jobs trying to provide for a high expense family? The cancer simply forced Walt to recognize where he really was and eventually what he really was.

Walt is evil but he doesn't want to accept it. What he wanted to happen was to make enough money to finally truly provide for his family, and then die. Instead "fate" cured him.

PS: Most economists accept that many completely unregulated market tends to monopoly's which try to extract rents. However, once a monopoly shows up they no longer accept that it's a 'free market' so the term 'free market' does not mean what happens when government does not interfere with a market. After that it get's complected as to where the line is drawn between free market and something else, however the bar is surprisingly high as for example moderate sin taxes don't prevent free markets.

For power usage, a model like the one used by Parallax's Propeller microcontroller might be interesting: Propeller has 8 cores. The entire thing can be clocked up an down like on a modern x86 chip. But it's also possible to put cores to sleep individually, which reduces power consumption even further.

I'm not sure how good an example Raspberry Pi is, simply because it includes features like a GPU. A computer probably really only needs one of most of that kind of stuff, so it would make more sense to look at the power requirements for a bare ARM chip than for a complete computer built around it.

-- change of subject --

What I've been running into (including hard and repeatedly over the last few days) is that parallelizing workstation-end tasks without killing performance in the process is hard. Shared-memory parallelism in particular is painful, because with too many cooks in the kitchen they'll end up spend more time trying to not pour boiling water on each other than making food. For example, every time you hit a memory barrier all the cores that are working against that memory need to stop and consult the L3 cache or, worse yet, main memory. That introduces an enormous stall (Of course if you're in a situation where non-trivial parallelizing is worth the effort, any stall feels enormous.), so it needs to be avoided as much as possible. . . which tends to not be an easy thing to do if you're doing shared-memory parallelism. Because if it were trivial, then you'd probably have been able to get away with shared-nothing.

Now the "lots of tiny cores" approach gets more interesting when you can get away with a more shared-nothing approach like what the article suggests. But it comes at a big cost, which is that you're going to take a massive hit on the kind of performance you can get on tasks for which parallelism is infeasible, or for which you don't have any programmers who are good enough at parallelization to do it (effectively the same thing). In those situations, you're going to be stuck watching one lone core play "Little Engine that Could" while all the other cores are dozing off like the lazy bums they are.

Meanwhile it solves a problem that I'm not convinced really exists. Time-multiplexing relatively beefy CPUs is pretty much a solved problem. Less so if you need real-time, but for everyday use there's really not much need to segregate processes to different cores when pre-emptive multitasking has been around on consumer systems for decades.
