There are a lot of subtleties with trading. To make money you need positive expectancy and you need 'inventory', or tradeable markets. They don't have to make large trades to make money. You have to consider transaction costs, rebates, avg win size, avg lose size, holding period, and a number of other criteria before you can judge these traders.

I don't claim they won't go bust, but I do take issue that simply because they make out-sized returns they are labeled charlatans.
DevKits have a notoriously bad development environment.

Granted, some things can only be done on the devkit, like access to the graphics card and the Sony graphics API, but doing compiler work or code that targets the SPUs is simply done better from Unix than with the native devkit options.

Simple Isn't Just Beautiful, It's Essential
I found Oregon Trail educational when I was young, but maybe in different ways than the game's authors intended. In the early versions of the game, you had to purchase food, clothing, and what not. I recall the prices of these changed as you went to various forts.

The obvious way to win the game was to buy a negative amount of clothing when the cost of clothing was high - the game performed no numerical checks when purchasing items. You could survive the journey between two forts with a negative amount of clothing, and when visiting the subsequent fort you could purchase all the goods you would need for the entire journey.

F5 Week in Review: March 22nd – 26th, 2010
This leaves quite a lot of questions...

Were the homework assignments of a type were using a computer to prepare them would actually help? Did the computers include the appropriate software that was needed to do the homework? Had the homework to be submitted in paper form and did the computers come with printers?
On their demo site they stretch the video, making it look janky on Chrome at least (I think that Safari resizes better but it's still not going to look as good as 1:1 pixel size) for no obvious reason or gain.

They also claim to have all the things that the article says are missing compared with their Flash based system, compare:

"But publishers can’t yet use it to create custom-branded players, compile audience analytics, provide viewers with social-media sharing options, or—crucially—serve up advertising."

"New HTML5 templates provide multi-title playlists, analytics tracking, social sharing controls, advertising insertion, and other capabilities to provide a customizable video experience built on open standards."

(I'll note again my personal pet peeve of using a non-open standard like H.264 while claiming it is open. If your customers value open standards so much, perhaps you should use them, no?)

Free speech is first and foremost political free speech. You have a right (and obligation) to assemble and speak on matters of public policy.

But you don't have a right to say just anything. Obviously if you decided to "out" all the spies in Bulgaria and that resulted in dozens of deaths? A crime has been committed.

I absolutely support political organizations and their right to speak out. But that's not a blank check.
this seems a bit strange to me, as I doubt a user is going to click, notice that something has changed, and then release the click, and not click again.

If you are really looking to alleviate issues on the back end, you're best to use javascript to disable or even remove the submit button if you don't want multiple clicks.

The author both insults users 'because they're users!', and then gives those same users the credit that they'll understand his minute UI change and accept it, even when it returns to it's pre-clicked state.

Greywater: Legal Liability or Untapped Resource?
Well, to tell the truth, if there's a 'lock', it's pretty obvious you shouldn't be doing it. If there's just a hash, it strikes me as simply a bad idea in the first place, no matter how long it is. Someone can just do 'copy image url' and have it work, with no challenge from the application. A shorter hash is especially bad because it makes them easy to guess at. I'm not saying it's "right" to copy images protected only with a hash, but it's like leaving an expensive bicycle unlocked on a college campus in the US - it's simply not very prudent. Of course in this case the users probably weren't aware of the problem, and the people who made the application are at fault.

Edit: like daleharvey says, the point is really that the hash simply happens to be difficult to find, whereas a proper application will challenge everyone who attempts to access the resource. For instance, say Alice looks at Bob's picture, and does "copy image url", and sends it to Carol. Carol has no way of knowing whether it's supposed to be private or not, since Alice didn't communicate that information.

Your post in the forums doesn't really mention spammers, but abusive users:

"PBH has run for over 10 years as a great place to get and share information about Colombia. Unfortunately, during the last few years, there has been a (very) small minority of people who thought it was ok to personally attack, threaten and harass, both on phb, on other websites and in real life, other members that they disagree with. You know who you are. "

It sounds like a different problem than just throwing up a captcha. Have you banned the users/IPs of the offending people? Can't you just add a "report user" button by each post and then have users or IPs with X number of reports automatically banned?
So the real question is what do 13-17 year old girls buy.

Idiot politician gets causality backwards; film at 11.
Any discussion of education seems to bring up a whole raft of ideas about what does and does not effect the young mind, and in which direction.

Plato, who was rather more observant and intelligent than you or I, felt that young people would be best served by learning only valorous stories, which showed just and good men triumphing and so on. He felt that the basic components of education ought to be music and gymnastic; and that an overemphasis on music would produce an overly intellectual and sentimental adult (an overemphasis on gymnastic would produce a brute).

Views seem to have completely shifted, to the point that Plato's program strikes one as absurd. However, I am not aware of any breakthrough in our understanding of the nature of education: our modern ideas are based, like those of Plato, on an observation of society, and of children, and of education, all colored by our assumptions about what is and is not valuable.

When I tell people that I played video games and read novels, they are no doubt inclined to think that I must have become smart and capable thanks to the novels and despite the video games. Why do we think that way, and not in the opposite way - that I became smart by playing video games, and despite reading lots of books? When I solve a hard problem, it feels more like the feeling I have in Quake, when I'm holding the entire playing field in my head and keeping track of where my opponents could be, than like the feeling I have while reading a book.
I took a look at the paper, and that is not an unreasonable explanation... It seems that the increased computer use did indeed reduce the time spent doing non-computer homework a bit, although the data is quite noisy and may not be statistically significant; TV viewing was similarly impacted. But what really took a hit was time spent reading recreationally. I can't help wonder what influence the reading had on grades relative to the homework.

Another thing in the paper that I found somewhat surprising was that slightly different parental rules had markedly different effects:

Interestingly, we find evidence that the presence of parental rules regarding homework mitigate
some of the negative effects of winning a computer voucher without affecting the gains to computer
skills and cognitive ability. On the other hand, the presence of rules regarding computer use reduce
the positive impacts on computer skills without improving academic achievement.

In an ideal world, neither the content owner nor the neophyte end user should even have to know, while power users get choice.

We've been quietly offering a player stack for months now: generally HTML5 > Silverlight > QT > Flash. Customers and viewers are delighted when the video plays on nearly anything w/o any extra effort. ("How'd you get this to work on my phone?!?")

Looks like our next step is using the HTML5 video tag as a placeholder for progressive enhancement though a better term for this use might be legacy enhancement. We want it to "just work" for most users, but let power users select the player that works best on their system (eg., hardware decoding support).

Choice of player should be at least as available as choice of video card for enthusiasts, and preferably as easy as choice of TV set for anyone.
True. I believe they're adding providers to the major VMs though (I mainly work in Python so I focus on the cPython VM, but I have heard of some early JVM introspection work too).
No, not directly. But they're trying to squeeze as much money as possible out of hardware and licensing by limiting users' ability to run Solaris for free on beige boxes, and that does seem to tilt the odds in the open question of whether Oracle will continue to let OpenSolaris thrive, or whether they will marginalize it to maximize short-term profit.

I say short-term profit because, in taking this course, Oracle seems to forget that many of the part-time tinkerers and educational or small business users whom they've just priced out of Solaris will be the ones making "enterprise" purchasing decisions in the future. This revised licensing agreement ensures that such users will be more comfortable and familiar with the competition instead--Linux, BSD, even Windows (Microsoft has done a fantastic job ensuring that their software is affordable in the education and small business sectors, while simultaneously maintaining a healthy profit margin in enterprise sales).

As an aside, everyone should definitely try switching to DDG as their default for a day or two- in-line wikipedia info and the !bang system are really killer.

I've switched to it full-time, and just do !google blah when I need to do an image search. The !bang flexibility makes it fantastic, and !twitter searchterm and !flickr searchterm makes it feel like you have a half dozen search engines at your fingertips. Because you can still execute google searches, it's not really 'switching from Google'- it's just an improvement, plain and simple.

While I can understand that shifting around the clock two times per year is annoying from an IT perspective, I for one really, really, really love the longer daylight in the evenings. Being able to walk home in daylight in the evenings, being able to be outside one hour longer in summer - all of it is such a nice thing to have.

If we were to stop shifting, I could live with that, if (and only if) we are constantly staying at DST and not at standard time.
I found a copy of the paper here:

http://www.columbia.edu/~cp2124/papers/computer.pdf

The homework assignments are not described, but given that many students do not have computers, it is reasonable to assume that the assignments at least did not require computers. The computer vouchers came with free "educational software", but few households installed it, and essentially no one spent time using educational software, in either group. Printers are not mentioned.

H.264 is going to come back and bite everyone who uses it. Its just a matter of time.
Amazing that I just now learned Ctrl-R after so many years of bash use.
I think the test should be whether the document has moral or just tactical significance. To give examples from the article:

Guantanamo Bay interrogation manual? Moral significance; leak.

Possible US use of chemical weapons? Moral significance; leak.

US order of battle for 2009? No moral significance; don't leak.

And in the interest of fairness:

Al-Qaida interrogation manual? Leak.

We need a picture of both/all sides' dirty laundry, and Wikileaks doesn't really give that.
"(I'll note again my personal pet peeve of using a non-open standard like H.264 while claiming it is open. If your customers value open standards so much, perhaps you should use them, no?)"

Completely agree. The marketing people have come in on this whole html5 thing and make using the proprietary H.264 seem open even though it is no more open then flash..

i actually ran an ad this saturday too...but I actually wanted to test how it'd work for selling something so I used an affiliate link.

So for $20 I got 19,303 unique views, 63,473 total views, 199 unique clicks, 215 total clicks. And a grand total of 1 sales.

The click numbers were different though, the affiliate program I used reported lower click #s.

I'll make a proper blog post about this later today, since I've been waiting for the 24 hour window for reddit to finalize their numbers.

Edit: here is the post with all the numbers/screenshots. Surprisingly I had a lower CPM than Gabriel which is weird since he was spending a lot more money than me.

New in Campfire: Conference calling
What is the message (or "punch line") that is supposedly clear here?

It seems poor households have higher computer ownership percentage than even the richest in this study, wich seems odd.

It also appears that while the poor have much higher ownership levels, they proportionately play less video games (though it's hard to judge from the graphs, note the scale changes from ownership proportion going up to 100%, to play ever day proportion only going up to 40%).

I've read several other studies which claim introducing computers in homes or schools is actually counter-productive if not done right but the rich/poor thing seems just to confuse this issue, and I'm really not sure what point is being made here.

Is he against computers or vouchers?

I believe the graphs are all post-voucher numbers. In other words, those below the red line are the ones who qualified for the vouchers, thus the jumps in ownership. The punchline is that while computer games increased substantially because of the program, using computers for homework did not.
> It would have been better to have a separate click counter in between.

I second this. You always want a way to track your actual clickthroughs so you can compare to your affiliate stats. If you're doing enough volume you can sometimes be credited for leads/sales that your affiliate network missed, but only if you can provide them with your own tracked numbers. And really only if the network values your traffic.
Ugh. I can't believe I'm engaging in this, but there really isn't any "debate" on this issue. At least not between people who know what the hell they are talking about.

Most of the solutions people are talking about when they mention NoSQL are not replacements for SQL databases. They are completely different beasts. I suppose if we're going to use strained metaphors I'd say SQL vs. NoSQL is akin to diesel vs. a V12. That is they are both fine technologies and, except for the very loosest of definitions, they do completely different things.

If you think NoSQL and SQL are actually battling, you need to do more reading...
Except government is willing to run its "businesses" not just at break-even, but at a loss. It also has a political power incentive to expand its businesses whether or not they are profitable in any sense.

This will discourage, and possibly prohibit (e.g., first class mail) private, potentially more efficient and profitable (in the true sense), competitive businesses from coming into existence.
