Yes! Common knowledge says that exercise helps you fight depression. If we see that some class of exercise is not as effective as another one (or is not effective at all) then we can start to ask ourselves how they differ.

I think you imply in your comment that "self-motivated exercise" is better than "externally facilitated". If that is true then we can start worrying less about selling the idea of exercising and more about thinking how to motivate a depressed individual.

On the other hand, if both cases of exercising offered the same results then we could say that it's not the motivation but the exercise itself who's helping us.
One more option is Barada PAM module+Android app. http://barada.sourceforge.net/
It is basically a HOTP implementation, where the token is protected by PIN (with PIN being a missing part of the shared secret stored on the token) and the original password is reserved only to be used on trusted machines (or) in case of losing token.
Wholeheartedly concur. I'm also a fan of Rob Pike's straightforward way of "getting to the core" of quite tricky concepts and putting them forth in such a way that they become obvious. Pike's razor, perhaps?
They are moving in the right direction. Responsive and minimalistic. I like it. I'm glad they removed that banner picture from the top.
Sorry, what's your point? Four of the jury members worked for tech companies.
It seems to me that the foreman misrepresented his memory of what happened with his own patent as fact to the other jurors to be applied to the current case; and he got some stuff wrong. It should be made possible in highly complicated cases like this that the jury could bring in experts (with the judge present maybe) to explain the real facts. Or for the jury to ask questions to the witnesses/judge during the trial to obtain clarifications they need to make their decision.

good read
Nothing is ever truly innovative. Nearly everything, quite literally everything, is built on something else.

Your first statement is being contradicted by your second statement which is almost the exact definition of the word innovation.

Just a few ideas (keep in mind these are pretty directly inspired by the ideas in this thread, maybe slightly re-hashed and re-worded):

Two-finger drag up to zoom-in, centered on where you first start the drag.
Two-finger drag down to zoom-out, centered on where you first start the drag.

Draw a circle (user can set whether clockwise or counter-clockwise) to literally outline what you want to zoom-in on.
Draw a circle in the opposite direction to zoom-out, centered on the centroid of the circle.

Similarly to the reverse function in Paper by 53, maybe a two-finger circular motion to zoom-in and zoom-out.
Alternatively, this could be a neat way to navigate forwards and backwards through your internet browser history.
Interesting; I usually feel tired after a bunch of weight-lifting but invigorated after a long hard run.
This study is not about 'making you feel good', it' about improving cases of clinical depression. If this study is sound, it would generalize to saying "exercise in addition to usual care is no more effective than usual care alone at reducing self-reported levels of depression measured by standard means".
Encryption prevents leaked data from being meaningful. No amount of server-side security, including query parameterization, can guarantee the absence of leaks. Client-side encryption makes leaks much less devastating.

How encrypting user data in JS on the client is different from properly hashing user passwords in JS on the client? It is now accepted that sending and storing passwords in plaintext is bad practice; the logical next step is to encrypt not only passwords, but all data on the client.
The title of this post does not match the title of the paper.

The report does not say "exercise does not make you less depressed".

The report mentions some of the weaknesses; some comments to the article do a good job at pointing out other weaknesses.

Exercise is not just pushed at people with depression to treat that depression; it's to help with other stuff too:-

* medication side effects (sometimes include weight gain or overeating)

* improving social life

* improving general health
This is the sort of thing that makes me fear for the Parses, Kinveys, and StackMobs of the world. Today it's Azure -- how many tomorrows is it going to be before it's Amazon or Rackspace?

Once the major cloud hosting players are in on the easy cloud-backed key-value store field, how much oxygen is there in the room for players like Parse? Especially when they themselves are built on EC2? I've got to think we're no more than 6-12 months from seeing that happen, and then they're going to have a tremendous fight on their hands, venture funding or not.
If anyone is still interested in doing Flash development with Flex, do yourself a favor and check out Haxe:

http://haxe.org/

The AS3 compiler in Flex is junk. My buglist over the three years I used it was nearly 100 items long. I don't know of a single unfixed issue in Haxe.

Plus, if you write the code properly, you can port it to nearly a dozen platforms (serverside, plus all of the ones on http://haxenme.org).

I don't make Flash games any more except for hobby projects, but migrating off of Flex was the best decision I ever made.
I have a really bad sense of direction, so if I'm going to be driving in an unfamiliar area, I'll always street view the highway to see what it actually looks like where I need to take an exit, etc. Couldn't switch from Google Maps without street view.
Apple is defaulting to Vimeo in ios 6 instead of YouTube, so don't count them out yet.
Juries are allowed and often requested to ask questions of the judge during deliberations, but it's up to them to decide that they need that clarification.

I've never been on a jury in a trial such as this, but just as you'll find in regular conversations, members of a jury will present themselves as experts and spout "facts" to back themselves up. A confident "expert" can convince a lot of people.
Interesting. I should note that most of this stuff (optimization, etc) is available through Haxe. Haxe can also compile to Javascript, iOS & Android; targeting just Flash is risky at this point.

Sorry to be off-topic, but is there secretly some good Lua documentation out there people use? While learning Lua yesterday (for use with Redis), I was astonished at how poor the official docs are. Even the book and the Lua Users wiki aren't that impressive. They all appear to be stuck in 1995.

I believe one of the nuances of the "growth hacker" title (cheeky title concerns aside) is the implication that user acquisition and product dev need to be interlaced. Consumer web is too competitive today to build a product and bolt on user acquisition. A role that sits on both the growth team and the product team is essential. Thus the birth of the growth hacker.

If the execute well on that idea, they do get credit, in the form of business. If you come up with Korean tacos first, and they're good, you get lots of business. We don't have to start shutting down your competition and guaranteeing you're the only Korean taco stand in town in order for you to benefit from your work.*

Invention and innovation cost a lot of money. The taco example won't work but if you invest a ton of money to develop something, you deserve a temporary monopoly on the innovation/invention so you could get a return on your investment.

If anyone would be allowed to copy you, the margins go way down and you'll never profit on the investment.

The goal is to promote progress; exclusive rights are a sacrifice, for a limited time only, made in order to benefit the public.

I don't see the conflict here. The public gets to enjoy your innovation/invention after a period of time which is designed to give you incentive to innovate/invent.

Without that temporary monopoly, no one would invest in major R&D.
All the communication channels may seem like information overload, but I would welcome it. I really like the part of open email (no more elite side bar conversations between people that don't know as much as they thought they did)

The best part is the IRC channel for chat that has a bot to log my status report (optional) and record for posterity and put it on the shared dashboard as encouragement, recognition and engagement.

sigh... I need coworkers that know what IRC is..

It is very common for new house constructions to either tear down a few adjacent house and build tightly placed houses on the land, or tear down a single house and build a larger house on it. This is specially true in high cost areas.
Now here's the problem. There is nothing secret about pinch-to-zoom! It makes sense to patent novel innovations in how a specific implementation of pinch-to-zoom works. But patenting a gesture that is so obvious you don't even need a scrap of expertise in the field to see? Ridiculous.

You consider it obvious, the courts do not. Simple is not the same as obvious.

Pareja Perfecta en Vivo
I believe that this link is the 460 patent that the guy mentioned:

http://www.google.com/patents/US7577460

The content presented in the patent drawings at the bottom are hardware-heavy, and the patent claims and diagrams discuss voltage control, etc.

I am not a patent expert, and not subject to the trial content. But I find it plausible that "processor", or phone architecture in general, might have been an important factor that differentiated Apple from the claims of Samsung's patent.
"three face to face sessions and 10 telephone calls with a trained physical activity facilitator over eight months" does not make you less depressed.
He clearly says that he wasn't assessing actual damages, but wanted to teach the offending company a lesson.

The whole thing is incredibly frustrating.
Oooh, good point. I will create a super-quick and dirty "Lua for Redis" tutorial for EVALSHA.com (pull requests encouraged!)
The title matches the results though...

"Results: There was no evidence that participants offered the physical activity intervention reported improvement in mood by the four month follow-up point compared with those in the usual care group; adjusted between group difference in mean Beck depression inventory score −0.54 (95% confidence interval −3.06 to 1.99; P=0.68). Similarly, there was no evidence that the intervention group reported a change in mood by the eight and 12 month follow-up points. Nor was there evidence that the intervention reduced antidepressant use compared with usual care (adjusted odds ratio 0.63, 95% confidence interval 0.19 to 2.06; P=0.44) over the duration of the trial. However, participants allocated to the intervention group reported more physical activity during the follow-up period than those allocated to the usual care group (adjusted odds ratio 2.27, 95% confidence interval 1.32 to 3.89; P=0.003)."

re exercise not being perscribed for depression. Current belief in Positive Pyschology circles (the founder of which invented the above mentioned Beck depression inventory) includes exercise acting as a treatment for depression.

"Besides training new habits and antidepressants, getting better exercise and a healthier diet have proven to have strong effects on mood. In fact, exercise is sometimes called the "miracle" or "wonder" drug - alluding to the wide variety of proven benefits that it provides.[55][56]" -- http://en.wikipedia.org/wiki/Positive_psychology

The main problem here is that "idempotent" means something different in math/CS than it colloquially does in HTTP.

In math/CS, "idempotent" means "has the same effect when done 1 time as when done n>1 times."

In HTTP, GET requests are often described as "idempotent" by someone who actually means "nullipotent" (i.e. "has the same effect when done 0 times as when done n>0 times"). This is because the spec describes GET, PUT, and DELETE requests as idempotent - which they are, it's just that GET requests are nullipotent as well.

Wikipedia mentions this briefly:

The Talented Ms. Hornstein: How Shirls Fooled The Valley
I suggest that you are not familiar with the spirit. It has nothing to do with protecting consumers. It has everything to do with encouraging innovation/invention that will eventually be freely available to the public.

To achieve that goal, investors need time to make their R&D investment back, plus enough profit to make the venture/risk worthwhile.
Generalize much? The build quality in the US exceeds China and Korea in almost every possible way. Every been to China? The walls of most new construction homes in Shanghai are made of cinder block or poured concrete. Terrible sound insulation as well as horrendous thermal insulation.

Increased home sizes would be hard to connect statistically to the reduction in sound insulation. Those two factors are not correlated at all. Many older homes have terrible sound insulation. In fact, older apartment buildings specifically are often terrible compared to new construction when it comes to insulation (both thermal and auditory.)
Anecdata: Earlier this year, I was exercising regularly. I had a lot of energy and felt great about my body and my brain.

Some stuff happened that made me stop exercising. It's been several months. I am generally kind of mopey, lethargic, and unhappy with myself. And putting on weight, which only makes me grumpier.

YMMV.
Of course not. You can certainly learn all you need to know on your own. However, that doesn't make the process of learning any easier. If you can get into a PhD program, it is a wonderful way to get access to information of various sorts.

If not, then the new free CS courses that are now being offered by Stanford and others provide extra help beyond reading books and papers. I'd highly recommend trying some!

Rich Hickey never went to school for Computer Science as far as I know. He studied music composition.
>* The title matches the results though...*

And it disagrees with the results of many, many other studies, some of which even quantify the exercise done instead of just relying on self-reported number of days of exercise.

It's a lot of work to set up billing in all the different countries, so they may not have bothered. There are also a lot of legal issue with different privacy laws (Europe being stricter) and censorship requirements (e.g. swastikas in Germany, denigration of Attaturk in Turkey). It's not likely that anyone's actively avoiding global availability, but it may be more worth for a period of time to use their limited resources on making the US version better rather than dealing with those headaches.
I think the foreman actually had a patent of his own. If that's true, he must have had very personal feeling towards infringers.

Yes. The huge thing that almost all discussions about online education miss or deny is how much of teaching is motivating students. This is true to varying extents across the socioeconomic spectrum. I believe we as humans are hard wired to feel more strongly about people we are physically near on a regular basis. And nothing online can replace that. I am willing to be proven wrong by this, but I would take most seriously those opinions of people who have a lot (a decade or more) of experience teaching both online and in person.

At this point, it just comes down to Intel spending more in R&D (http://newsroom.intel.com/community/intel_newsroom/blog/2011...) than AMD makes in revenue (http://www.anandtech.com/show/5465/amd-q411-fy-2011-earnings...) means Intel is at this point just throwing money at rapid release fabrication tech combined with their tick tock being so effective (they had to be after getting wasted with the Pentium 4 stagnation). Even if AMD didn't blow tons of market cap on buying up ATI, they would still be looking at Intel just being an order of magnitude larger than them outright. They struck gold with the Athlon 64 line and that is the only reason they ever overtook Intel, which like other commentors mentioned, was because of Intels own hubris.
You remind me of http://www.gocomics.com/calvinandhobbes/2009/02/18/
This whole case genuinely scares me for our legal system. It seems like once they found a jury foreman who had his own patent and played to his fears of "what if someone did this to my patent" put himself in Apples shoes and did all he could to make sure they won. Kind of feels like they shouldn't have even bothered with a trial once people are saying "yeah, we didnt even bother to consider samsungs arguments of prior use, we just didn't have time" when the jury came back with a verdict VERY quickly. If you listen to the interviews it sounds like almost every juror decided "well the foreman seems like he knows what hes doing, I'll go along with that." This is not the way our legal system should work.

Maybe they assume that a 10-number password is likely to be a phone number, and so constrain the three most significant numbers to just valid US area codes. Add in other rules, like the fourth digit never being a zero, etc...and the space is pared down quite a bit.

"too abstract" is not a phrase I'd think to associate with a lisp. It's all just data. If anything I'd expect people to say there's too little abstraction.
I've often wondered about this. I've been through a couple major depressive episodes even as I was in peak physical condition. I was doing high-intensity boot camps 4-5 days per week.
I've seen this too. However, they seem to have made improvements in Firefox 15. Previously, Firefox would take around 3% CPU with just the start page open; visiting a page with an animated GIF would push it to 12%; and, most troubingly, CPU usage would stay around that level even after the page was closed. Now, the same page still takes around 11%, but Firefox stays at 0% with just the start page open, and it goes back to 0% once you close other pages.

If Vimeo (or some other site) became a serious competitor to YouTube is there any reason to expect that they'd be any less deferential to the labels than YouTube is?

I'd say no, because I'd expect the labels to keep throwing lawsuits at a serious YouTube competitor until they were. Moreover, the labels have a new piece of ammunition they didn't have against YouTube: YouTube meets our requirements, why can't you?
This is why I don't want to buy a second-hand bike.
I would say no, but a good chunk of knowledge is (though probably less is required than imagined) and if the academic methods of acquiring knowledge suit you (for many hackers they don't) then a Ph.D is a fine way to get a good chunk of knowledge. Here's Rich Hickey's recommended reading for Clojure specifically: http://www.amazon.com/Clojure-Bookshelf/lm/R3LG3ZBZS4GCTH/re... It's not exhaustive for even functional programming and design let alone the entirety of computer science, but it's certainly a good chunk of knowledge enough to do awesome work from.
