In essence, what's being computed is the sum of 1 + 1/2 + 1/3 + 1/4 + ... (which we call the harmonic series), and you're trying to figure out how fast it reaches a given number. You've experimentally verified that it takes exponential time, which is another way of saying that the sum grows like a logarithm.

To verify this mathematically, use the "integral test" [0] twice. The linked proof shows that the sum of k terms is larger than ln(k+1). It turns out that, by drawing the rectangles under instead of above the curve, you can also show that the sum of k terms is less than 1+ln(k+1). Thus, the long-term behavior of the sum is essentially the same as the long-term behavior of a (base e) logarithm.

I like what I see so far. I'm learning programming, and jut went through the first lesson of CS 101. Here's what I liked:

1. The videos are supplemented by written course notes. This is useful for people (like me) who prefer text to video.

2. There are quizzes to confirm understanding, and they come very shortly after learning a concept. This provides fast feedback.

Crucially, the quizzes can be repeated until you gets the answer right, and an explanation follows.

The first lesson is pretty basic, but the overall learning framework seems promising. It's focussed on making sure you understand.

I'm just using this as a supplement, but it will be interesting to see where it goes.
These kinds of judgements-wrapped-in questions always come off as a bit sophomoric. It's like an artist asking, "why do some painters still use oil instead of colored pencil? Pencils are erasable, and so much easier to work with. No nasty fumes!". Or an architect-in-training asking, "Why use concrete and steel to build skyscrapers? They have so many constraints, and are so ugly, and hard to work with." I appreciate an iconoclastic spirit, but not one based on ignorance.

I imagine much of the stuff in the initial 30 seconds is necessary overhead that you would incur anyway.

I prefer that a game does automatically load the last save point since it is less effort to simply click "continue" than it is to wait for something to load which I may not even want to do.
They're both essentially a single button click. Technically, there is a difference. Realistically, there isn't.

Hi Tazzy, funny, I moved from NYC to STL about a year ago. I know what you mean.

My take has been to mimic the entrepreneur community infrastructure represented by an NYC on a smaller scale here. Building community here has been my biggest priority.

The community is here. It's small, but it does exist. And the capital--also small, but it's coming. I don't think $500k is really that impressive. One company should burn through that much on their way to VC, let along a myriad of startups...

"Once the people come, the capital will come." We are in complete agreement. Now we want some more people--how does $50k sound? ;)
Though "formal science" is not a familiar term to me, I take your word for it and hear what you are saying. However, I always considered mathematics to be it's own thing, different than science. Real science is physics and chem and then biology starts to merge more into a body of knowledge.

Anything that has "science" in the title isn't really. And in line with that, I consider "computer science" to be a misnomer as it is more accurately categorized as a branch of mathematics. And computer science is, of course, completely distinct from software development, which is a craft.

All that said, I would be hesitant to put psychology and psychiatry in the same boat. Neither one is a hard science, but psychiatry is much less likely to be anyone's fall-back major.

Looks like Andrew Warner helped Suster write that headline :-)

This was a really great interview though. Definitely recommend watching it.
There was teaching, yes, but there wasn't modern, peer-reviewed research. Even Newton spent half his lifetime as an alchemist. It just wasn't that clear that science was the more fruitful endeavor.

I'm not claiming the Royal Society 'invented' peer-reviewed science. It wasn't a dramatic moment of epiphany, just a gradually growing insight that spread through society. And the Royal Society was at its forefront.

The algorithm achieves significantly higher accuracy if it has more text per author. Also, if you're willing to do human analysis on a few dozen candidates after algorithmically shortlisting them, that gives you a further advantage. Finally, there is much room for straightforward algorithmic improvement (e.g., ensembles of classifiers) that we didn't have time to fully investigate. In short, IMO it's just a matter of more data and slightly better ML, not fundamental improvements.
Plato's Akademeia was for teaching. The modern research-oriented connotation of the word only dates from 1880 or so.

Yes though I suspect Photoshop's load time could be significantly reduced by limiting the features available at load time. If the method code for the 223rd most popular effect is loaded into memory prior to the user being able to do anything, Adobe is doing it wrong.
I would say that overall modern versions of photoshop do feel faster than older ones.

Of course photoshop is intended for professional designers with reasonably high end computers, it was never intended for the use case of somebody using a netbook to touch up a few photos as there are other programs for that.

As technology has improved people will expect more from designers so they need more powerful tools optimised for working with large file sizes etc so Adobe are going to expend more effort maximising performance on higher end modern workstations then they are making sure it loads quickly on a five year old netbook.

Just because every teenager wants to use pirate CS4 to tack together a logo for their band does not mean that is what adobe should optimise for.

I personally know one company which lost a court case based on that defense. Not in US/under DMCA, though.
You would lose interop with existing email infrastructure. the problem is that hosted email brings everything back to being too centralized (for eg. most of the email I send doesn't leave the google servers). Take a product that implements its own smtp server, nice PGP integration and a nice interface over it like the one in OP. users may be more likely to want something like that (I know I do - I can't wait to switch away from Gmail) rather than an entirely re-invented messaging system.
It means that they don't work unless the user enables tracking by third parties on first party websites.
The approach she took to raise funds is very inspiring. Great story.
Why people think Computers Can't

I see so many articles talking about how email is dead. I could care less, but if there is one indicator to me that email is dead is that nobody is willing to create their own email service anymore. Instead, a typical email start-up will just be skinning Gmail.

I have been contemplating on moving away from Gmail, and that's the only reason I only clicked the link. Of course, there is no way of getting away from Gmail with this service.
As far as I know, the proper way to create a modern web app to deal with location.hash fallback and pushState, replaceState etc is to use https://github.com/balupton/History.js .

Great paper, glad to see the fruit of your efforts.

I guess you did not look at texts with multiple authors, or professionally edited texts? I am curious if a different editor, or publication house style, can be detected.
The list of examples is beside my point, and the point of the original article.

The original article seems to be talking about SIMD as a general-purpose computer, with general-purpose applications, not as a secondary unit to another system.

My comment acknowledged the uses you list above, especially for GPUs, in which SIMD is a secondary processor to a controlling general-purpose computer.

I programmed Conway's Life on a 32x32 DAP in 1986, and I guess I feel like I've seen these claims once already.

I'm been experimenting with UHC's js backend. One of the things that struck me was that in Haskell if I have a function like:

forever :: Monad m => m a -> m a

I can use it for either asynchronous or synchronous javascript, e.g

forever :: IO a -> IO a
forever :: ContT r IO a -> ContT r IO a

The same function can take a synchronous js function or an async js function and run it in an infinite loop. For this reason, I think that if you want to learn from Haskell in writing reusable js then you should look into monads.

Ideally you string them along while on speakerphone, and engage in some sort of necessary, but low-mental-effort work you've been putting off.

True, although from what I remember the flash development tools seemed to provide much functionality that seemed to be aimed specifically at creating things like this.

IIRC there was something that was basically a "flash intro wizard" however this may well have just been added due to demand from developers for such features.
Immediate requirement for Natural disaster
As we know that natural disaster is uncertain nobody knows when it occurred. You must be pre planned yourself how to react when disaster occur. There is some important point .To control you is the immediate requirement after a natural disaster. You should try to eat normal meals a day even after a calamity. You may not feel very hungry. This is required to cope up with the situation and make decisions.
Also, because Objective-C doesn't support namespaces like C++, the prefixes sort of serve as a namespace and are there to prevent naming collisions. It's only a convention though, not a requirement.

Congrats to Fluent! Great design and a slick UI.

The stream view is an interesting concept, but we've found that many people don't have a nice inbox of messages as shown in the preview. In fact, it's quite the opposite: messages from friends, family, and coworkers are often overwhelmed by notifications, newsletters, and mailing lists. However, your Amazon shipping and Twitter notifications aren't spam, you just don't want to see them in the same context.

I'm working on Glider (http://glider.io), a fix for the mess in your inbox. You already know which kinds of emails are important to you, so instead of obscuring that information, we think the best solution is to sort and display emails by sender and context.

We did a soft launch on HN a few weeks ago (http://news.ycombinator.com/item?id=3519917), and would love to know what you guys think. Good luck as well to the Fluent team!
Do you think that these are qualities unique to Saint Louis or the midwest?

Do you think that NYC or SF don't have their hanger-ons, dilettantes and blowhards?

What frustrates me so mightily about the overly-dour pessimism about the midwest is the total neglect for all of the things that do happen here, and a lack of recognition of all the awesome midwesterners who leave the midwest just to do awesome stuff elsewhere.

I grew up and went to college in Columbus, Ohio thinking that the tech scene was elsewhere. It wasn't until I had already graduated and made plans to leave that I learned that, actually, Columbus has a world class Ruby community I'd simply not yet heard about.

I am still trying to figure St Louis out, having moved to Columbia Mo, 6 mos. ago, but I am skeptical that the community that puts on Strange Loop every year, has had companies like Slicehost come up out of it is really the barren wasteland you make it out to be.

Cheers, a helpful and extremely likely case!
Seems implausible. For one obvious example, any web store that sends you MP3s you've purchased via e-mail (I've used a few) would now no longer function because GMail would delete the MP3s before you could even download them to listen to them.

Difficult to confirm or disprove without a few examples (artist name, track name) that people can test with their own legit (copyrighted) MP3s.
You remember correctly! If you don't mind me asking, who were you with? I (their 15 year old intern) was there from August-November and got to know the place pretty well :)

Personally I don't care how long it takes an app to start provided it stays running once it does start. If I'm doing non-trivial work in an app the boot time is negligible compared to the time I spend working in that app.

Well, you're right and you're wrong. I'll be specific, since you are:

Twitter is sending down the home timeline as HTML. In fact, what most people are looking for when they go to twitter.com is their home timeline so I'm correct, this is what they are doing (at least in new-new-twitter which I think almost everyone now has). You're also correct, when you go to twitter.com/#!/n8agrin you get your timeline in the background which is then replaced with my tweets. However it wasn't always this way. At one point in time, going to twitter.com just downloaded a bunch of javascript and an HTML bootstrap. The whole site was generated by javascript. I know this because I worked on it.

Technically pushState doesn't really have anything to do with the practice of progressive enhancement or making anything "much faster". You can make pure javascript sites very fast, you can make serving straight up HTML very fast, you can progressively enhance HTML without pushState. pushState is really just a way to manipulate the history of a browser, while optionally changing the browser's current url, without a page refresh (read more here: https://developer.mozilla.org/en/DOM/Manipulating_the_browse...). You can use it to do a lot of things, one of which is to have it serve as one part of a solution for sites that behave like single-page apps without having to resort to the fragment identifier (http://en.wikipedia.org/wiki/Fragment_identifier), forever vilified as the hashbang.

Entire essay contains many insights but this paragraph caught my eye:

"A system that allowed small business to simply hire people with a handshake and pay them with a check, notifying the government once a year of amounts paid and to whom (and with the ability to deduct all reported wages from gross receipts for tax purposes) would likely increase the rate of business formation and hiring and if anything would result in a net increase of revenue for the government as more jobs were created and as fewer start ups and small enterprises would chose to operate under the table."

This is how it already works when one corporation does business with another one. Whether it is two one person corporations or larger firms on one or both sides of the equation.
