It's interesting that the book cited in the submitted article

http://www.amazon.com/Secrets-Mental-Math-Mathemagicians-Cal...

(this link is to the United States Amazon site, while the submitted article link was to amazon.co.uk)

is written mostly by a professional mathematician, but with an introduction by an author who is a historian by higher education. Michael Shermer writes a number of interesting books,

http://www.amazon.com/Michael-Shermer/e/B001H6MCNY/

of which my favorite is Why People Believe Weird Things: Pseudoscience, Superstition, and Other Confusions of Our Time.

These guys are obviously charlatans. He claims to reliably make >$100K/yr trading his $100K account. If he could really generate 100% return on capital, he would be the richest person in the world. (Or... at least he would have more than $100K to manage.)

The author isn't totally uncritical, but it's annoying that he gave these guys so much space in the Times to advertise.
"the impact of small phase altering events is unclear".

according to the abstract the study suggests a link, not causation.

[edit] - depending on how you interpret the word "potentially". i read it as "a potential explanation for the phenomenon".
Because that's what the author really wanted to show with the rest of his post—how to be an insightful person that would then have insightful things to blog.

Even if the "blogged X" usage is accepted, having insightful things to blog means you could blog insightful things. Not blog insightful. Otherwise you could also write insightful. That's nonsensical.
Yea, this is the type of thing I'm worried about and my knowledge of law is basically nothing.

I would hope for some type of letter asking me to remove content before anything serious happened.
Very interesting approach. For those who are interested in more "different" math, google (or wikipedia) for "vedic math" (from Sanskrit Véda, "knowledge"); an ancient Indian system of mathematics a bit different from the typical western teachings, said to better adhere to how the human mind works. Some amazingly efficient techniques for arithmethics on both paper and in head are to be found there.

Thousands of private fotos leaked, privacy disaster for Quiptxt.com users
I support the idea of open government enormously. We make too many things secret, and a government with so much secrecy is not responsive to its citizens.

Having said that, I also support the idea that some things -- some very few things -- should be kept secret.

Wikileaks does not seem to discriminate between these things.

Therefore I cannot in good conscience support Wikileaks with their mission to make everything they find public. If, as the article indicates, they're in it for personal kicks then that makes it all the worse.

It's 2010. You'd think the average person/whistleblower would have enough ability to self-publish for the entire world to see, right? If Wikileaks isn't providing some kind of independent, third-party vetting or creating some standards for what can be published or not, what value do they bring to the table?

Canesta Has Survived to Beam Up Your Gestures
Key quotes from the article:

"At exactly the time when U.S. government secrecy is at an all-time high, the institutions ostensibly responsible for investigation, oversight and exposure have failed. The American media are largely co-opted, and their few remaining vestiges of real investigative journalism are crippled by financial constraints...

The need for independent leaks and whistle-blowing exposures is particularly acute now because, at exactly the same time that investigative journalism has collapsed, public and private efforts to manipulate public opinion have proliferated. This is exemplified by the type of public opinion management campaign detailed by the above-referenced CIA Report, the Pentagon's TV propaganda program exposed in 2008, and the ways in which private interests covertly pay and control supposedly "independent political commentators" to participate in our public debates and shape public opinion."

again, i'm tired of repeating this, but wikileaks, at least to my mind, is not a news organization, it's a medium for whistleblowers to release information. can't be objective!

it's a job for news organizations and journalists (some of whom might be supporters or volunteers of wikileaks) to analyze and present this released information objectively.
> can't be objective!

I disagree in the strongest way; they can and should, in my view, be entirely neutral/objective in how they release information.

Im interested in how it is arguable they should be allowed to put their opinion or spin onto a release and it be considered ok?

The F.A.S.T. Diet
Dieting is hard. Some diets are just so restrictive that they set us up for failure. Others are more reasonable, but making the lifestyle changes that are necessary to lose weight is no small task. We need lots of support to keep us motivated and see us through the tough times if we are to succeed.
What one has here appears to be a "natural experiment," in that the researchers looked at when daylight saving time began as a policy in Australia. (It is already known to suicide researchers that seasonal variation in daylight length is a strong risk factor for suicide, resulting in seasonal variation in suicide rates.) The way to check this conclusion would be to look at other countries (or states in the United States) where policies on daylight saving time have changed over the years. This is not an ideally controlled experiment,

http://norvig.com/experiment-design.html

but suicide data are gathered by a standard World Health Organization methodology all over the world,

http://www.who.int/topics/suicide/en/

and when other national policies change in a country, or differ between countries, it can be useful to look at whether or not those policy differences make a difference in suicide rates. Sleep regulation is well known to be an effective treatment for mood disorders, so this is a plausible correlation to look at to see if there may be a causal relationship between the policy and the medical outcome.

Ask HN: Please review my cross charting fitness app
Let me start by saying there is plenty of competition. There are lots of ways to track your workouts etc. None of which I felt were simple enough for me (they all have communities, stores, or complicated methods of entry, or every other feature under the sun).

I really just wanted a place to post my maxes when I hit them (in regards to weight lifting) and continually see how well I'm progressing (on a chart).

So thats what I built. What makes it a little different however, is all of the exercises are graphed on 1 chart, so you can see correlations between increasing weights etc. I might also add body weight as a base line measurement as well as more charts showing other stats (average monthly increases etc.).

Odd typo in the Techzing post title I assume.

My fault for copy-paste-haste when creating this item. I've corrected the title here on HN.
Hi, looks like something which should have a free/premium version. However, I don't think that you should limit the number of users/questions that can be asked by visitors. But extra features (such as metrics, customer subscription) should be charged for. This is only my opinion of course.
There's no question there are a lot of snake oil salesmen in this business. That said, there are a small number of elite traders out there that make these types of returns and are fully content not growing their account infinitely.

Also, as your account gets larger, trading it for the same types of returns becomes more and more difficult just because of the position sizes you have to take. This reason alone is why the little guy still has a built in advantage over institutional traders who have to move around very large amounts of money to be worth it.

I don't know if these guys are charlatans or not, but there are guys and gals doing similar things making similar returns consistently.
It would be nice if it were so simple -- wikileaks is just a version of YouTube.

But they're not. They don't publish everything they get. They have an agenda. And they don't seem to have publication guidelines, which even YouTube (and every other quasi-anonymous publisher) has. In addition, everything they publish is supposed to be against the wishes of some national government somewhere.

Nope. Once they gave up neutrality, they're not a publishing channel. They're a political cause masquerading as a public service.
Wrong doesn't necessarily correlate with "non-mainstream". There's a point to be made here, but all I'm getting from this article is "famous people can be incredibly wrong too".

Can people please stop boasting that they are retiring at 20, 25, etc.?

If you drop out of work and start your own business, you have not retired. Achieving financial independence and not working for other people is great. Retiring is not about financial independence, it's a mindset - not undertaking anything else in your life. If you retire at 25 you are just lazy.
Consistently is a stretch. the journalist covered the Taiwanese study. Only 20% were profitable (winning streak). Only 1% were consistent.

Author of the article here. I'll try to give a quick informal explanation. If you look at the type signature of `>>=`:

m a -> (a -> m b) -> m b

Let's suppose there's a HakyllAction monad. The >>= signature would be:

HakyllAction a -> (a -> HakyllAction b) -> HakyllAction b

If we implement this operator, we get a value `HakyllAction a` and a function `a -> HakyllAction b`. We can look at the dependencies of the value, but we don't have access to the dependencies of the `a -> HakyllAction b`. If we want that, we need to apply it to the first value.

This goes against the idea of dependency handling -- we want to know the dependencies first, and then only execute the function if needed.

Hope this helps.
Proposal of new UI element for windows in Ubuntu
Assuming he compounded all of his returns he'd be the richest person in the world. Making 100% on 100k is demonstratively easier than making 100% on 100m and is not unheard of. So why doesn't this guy manage other people's money? No where in this article does it mention his account volatility or average draw down. This guy might be making 100% return with a peak to valley draw down of 75%.

Don't assume they are charlatans just because you don't understand what they're doing.

No one hates selling. People just hate selling crap. I used to work in a retailer when I was a kid and hated the job, hated the products we had to "push", and hated everything about the company.

Now, I make stuff, I don't do sales but I don't mind talking about my work. I'm probably not a good salesman, the people that do it are really good at it. There are entrepeneurs that love what they do and it shows in their pitch and there are entrepeneurs that love money and could sell water to a fish. I like the first kind, the later can drown.

If you are an entrepeneur that hates your product you should make a different product.

Installing and using Apache Cassandra With Java Part 4 (Thrift Client)
When you go into a bookstore, do you routinely get clerks saying "Thanks for coming to our humble establishment. Prior to being allowed to actually see the books, we'll need you to sign this waiver of liability, which disclaims any responsibility on our part if you should open one of the cookbooks and cook Thai food while having a lethal allergy to peanuts."

This has not been my experience in bookstores. If you're totally unable to sleep at night because you live in fear that vampires might descend on you if you do not say the right words and make three circles clockwise prior to opening for business, then say the right words and make three circles clockwise. Otherwise, go solve a problem for people.

If you launch something like QuipTxt, make it obvious to people that their images are public, so that the idiots who harbour the impression that stuff uploaded on a public URL on a free website don't come running at you with pitchforks.

Two things in this story that are not new, but still amazing to me.

1) A significant portion of people love taking pictures of themselves naked. This portion seems to be growing.

2) Another significant potion of people love publishing and making fun of people for whatever reason they can find. These people will dig through your trash, hack your servers, socially-engineer your passwords, etc. The more they can publicly debase you the happier they are. This portion of the population is also growing.

Yes, I understand the technical angle to this story is whacked security. I'm just amazed at the comments over on reddit (I don't visit reddit very often) From reddit I surfed over to a couple of other links (drama-a-pedia or something?) and the festival of public debasement continues. Somebody even mentioned hacking some girl's senior picture and uploading her naked pics. Man that has to make you feel really special to do something like that.

Did you read the second and third pages? It's not obvious that it continues, and most of the explanation is there.

Basically, the EU was going to say that open standards and open source were good things that should be promoted for the benefit of the citizens and businesses of the EU.

Not a particularly controversial position as various US governmental organisations such as the Department of Defence, and various other national bodies like China have said similar things.

This has, naturally, been lobbied against by Microsoft. Privately of course, because it, at the very least, appears shady to be arguing against open standards and free competition. And it seems they may be on the verge of getting what they want, which would be a bad thing for almost everyone but them.

Regarding the openness continuum, do you really want a government document on interoperability to say that one way to achieve "openess" is for everyone to use the same proprietary product?

"While there is a correlation between openness and interoperability, it is also true that interoperability can be obtained without openness, for example via homogeneity of the ICT systems, which implies that all partners use, or agree to use, the same solution to implement a European Public Service."

Note this seems to contradict common sense as well as many of these definitions which indicate you need at least two systems to "interoperate":

Well in all fairness, you have the option not to upgrade to 3.21 if it really means that much to you. I think a lot of this is blowing in the wind. I'm sure most people don't even know that you can install Linux on the PS3. Plus the RAM limitation (256 mb) along with not having real access to the RSX makes me go eh.

I agree that companies shouldn't promise one thing and then two years later do something completely differently.

I've known about DSPS for about five years now. Problem is, the world doesn't accommodate you anyway (my time in HS/college was absolutely terrible; I'm just getting out now), so I've resorted to using tricks like light therapy and taking melatonin at night. Even tried the Tim Ferriss method of ice baths when I needed to sleep for finals. My experience is that I can only temporarily hack my sleep to be 'normal' for about two weeks, max, and then it veers off again.

Hell, this is probably a big reason I'd like to get into startups and such. I don't think I could survive a normal job schedule and the progressive shift is too unpredictable for most companies.

Considering games like fl0wer were made with the PhyreEngine, awesome game by the way, I don't think this is really going to be an issue.

I doubt most gaming companies were using the OtherOS feature in order to learn how to program on the PS3, they hopefully have dev kits.

It's a reactionary move precipitated by the hacking done by that geohat guy. A lot of gaming companies think that by making a console pirate proof (which the PS3 has been so far) saves them money in the long run.

Look at the whole Ubisoft Assassin's Creed 2 mess.

In Sony's case I think they partly blame the PSP's problems on piracy and don't want it to happen to the PS3.
