Hackers who got real jobs, by hacking
Published: Thursday, June 30, 2011 | By: DennisI always wondered if hacking could eventually pay off, or if it was like any other crime with an expiration date. It would seem that for a select few their hacking roots had paid off.
Hotz is clearly a smart man and Facebook was smart to hire him, and while an argument can certainly be made for hiring gray-hat hackers, where do you draw the line? Sophos security consultant Graham Cluley has been one enduring critic of hiring black-hat hackers and has blogged in the past about the negative precedent it sets for aspiring young tech mavens who may not know the difference.
The thing with hackers is that they become good because they are curious about how things work. This is a talent many high paid developers are not concerned with and that blindness is why we have exploits and a market to hire hackers to help make systems better.

Women sexually attracted to Porsche-driving men
Published: Thursday, June 30, 2011 | By: DennisWho knew you could get girls by just driving a fancy car?
In what may be one of the dumbest, most obvious studies in a long time, USATODAY.com's Your Life reports that researchers at three universities found men's conspicuous consumption is often driven by a desire to have uncommitted romantic flings.
-- snip --
This is the best part of the article, and so true on an infinite number of levels.
So we suspect the lesson here is buy the Porsche, have multiple flings based on your German-engineered sexual prowess, but if you find the right woman and want to make it permanent, you'd better buy a Buick.
Not sure a Buick is the best choice but ya you get what you pay for and in this case, the more you pay the more they will expect you to pay.

k|ngp|n Cooling Liquid Nitrogen Containers @ techReaction
Published: Wednesday, June 29, 2011 | By: DennisNot a bad review, no real detail shots of the containers or how to install them but I guess they figure if you are reading it you know a little something about them already.
When k|ngp|n got started, one of the major hurdles was how to properly cool his components with LN2. Since devices did not exist with which he could accomplish thos, he started designing and building prototype LN2 containers (“pots”) which he could mount to the computer hardware in order to apply the LN2 to effectively cool the components.
I do like how most reviewers are very guarded in showing the particulars of each base and what makes each one different. If given the chance to do a review I might do the same, but only in fear of what the community would do.
Regardless I'll be trying my hand at LN2 this summer after I get a few other projects done and out of my way.

The Neuroscience of the movie Inception
Published: Friday, June 24, 2011 | By: DennisI'm the type that likes all kinds of movies and doesn't go to the theater to rip a movie apart but rather to turn off my brain, sit back, and watch the show. That's not to say that after the movie I don't have an opinion of the film but rather that I don't concern myself with that going into the film or even if my 8 dollar popcorn was worth the wait.
With that being said I do have a favorite film type which is what I call the thriller that makes you think. This is also the kind of film that begs you to pay attention for subtle details that may reveal a crafty plot twist or somehow expose the mystery. The best of these films send you on a convincing ride that may later offer up some alternative logic that leaves you wondering.
One such film is Inception, a movie based on the concept of lucid dreaming and how you may exploit dream space in order to steal ideas from someone, or in this case infect them with a new one.I'd argue that Inception tries to collapse the already thin distinction between dreaming and movie-watching. It gives us a movie in which most of the major plot points are simultaneously nonsensical - Why are we suddenly watching a thriller set in the arctic? Why are all the subconscious mercenaries such bad shots? Why don't Cobb's kids ever age? - and strangely compelling, just like a dream. And so we bite our fingernails even though we "know" it's just a silly movie. Thanks to the subdued activity of the frontal lobes and the excited visual cortex, we sit in our plush chairs munching on popcorn and confuse the fake with the real. We don't question the non-sequiturs or complain about the imperfect special effects or the shallow characters. Instead, we just sit back and watch and lose track of the time together
The wired.com article explores the science of Inception and makes parallels what happens in the dream world to what happens when you simply lose yourself in a movie. Good stuff.

Bitcoin Giant Mt. Gox Promises to Change Post-Hack
Published: Thursday, June 23, 2011 | By: DennisI like to think that I am up on some of the latest developments on the ole interwebs but the truth is I only know what I care about and distributed computing isn't on my radar. However when Podcast Co-Host, Darren, sent me this news story it sparked my interest.
A virtual currency system that can be traded for actual USD, and much like the stock market these Bitcoins have an exchange rate that changes on a regular basis. However, here is the kicker to get Bitcoins you "mine" for them by running a program that generates a "block" that ends up being worth about 50 Bitcoins. You can then take that "block" and trade it for real currency.
At the current exchange rate that works out to be about $850US.
Of course with the good comes the bad which is the basis of this news report, it would seem people have tried to fraud the system, which turned out to be rather easy since they only used MD5 encryption to secure user accounts.The fact that Mt. Gox was using salted MD5 is somewhat disappointing as for a financial institution -- particularly an exchange that handles nearly 90 percent of the $130M+ USD of Bitcoins in existence -- you would expect them to only use the latest and greatest in encryption (like the salted SHA-512, which they are now migrating too).
The fact that up until 2 months ago they used unsalted MD5 -- which has been easily crackable by rainbow tables and brute force attacks for years -- is downright disturbing. As it is, it appears very, very lucky that Mt. Gox decided to migrate to salted MD5 when it did. Otherwise the damage might have taken weeks or months to revert, not days.They claim that the new accounts will be encrypted using SHA-512 so account information will again be secure, but if you read carefully as part of the "upgrade" the Mt. Cox exchange also rolled back all transactions to a previous time and thus negating any trades that occurred during the missing timespan and in the process also altered the exchange rate.
Bottom line, this is like shorting a stock right before a major disaster. -
EVGA GeForce GTX 580 3GB Review @ Hardware Canucks
Published: Thursday, June 23, 2011 | By: DennisIn the world of high resolution gaming, multi display graphics, and multi gpu rendering you have to ask yourself. "How much video memory do I really need?"
Much like with your system memory, more is better, especially when you consider the amount of post processing that happens in games or even calculations for 3D Vision and CUDA apps. In those cases every little bit helps.
In the last few months it has seemed like custom GTX 580 cards are being launched at a nearly breakneck space. Amid the hoopla surrounding some high profile launches from MSI, Gigabyte and ASUS, EVGA silently introduced their own "upgraded" GTX 580 which sports 3GB of GDDR5. While it shuns higher clock speeds and upgraded cooling, EVGA backs it up with their legendary Lifetime Warranty. But will this be enough?
Not to mention, the card looks cool too.
