More passwords hacked and leaked
This time, whoever was behind the attack got around 1.5 million website login credentials, 320,000 email account credentials, 41,000 FTP credentials, 3,000 remote desktop credentials, and more.
A look at the passwords shows a keylogger may have been overkill, however. Trustwave reports that the most common passwords were "123456," "123456789," "1234," and "password."

10 Habits to Break in PS
http://psd.tutsplus.com/tutorials/tools-tips/10-bad-habits-to-break-in-photoshop/
2. Deleting and Erasing Instead of Masking
This bad habit is also very common among Photoshop users. Deleting and erasing parts of a layer’s content is a very destructive way of editing. To avoid losing image content you should always consider utilizing one of the following features in Photoshop.
- A Pixel Mask
- A Vector Mask
- A Clipping Mask
The easiest way to hide parts of a layer is by adding a mask to the layer. Masking will only temporarily hide the selected parts of a layer, which can always be made visible again by deactivating the mask.

Computer Science: Job prospects?
Last year, just 1.4 percent of high school AP students took the computer science exam, compared to almost 40 percent that took exams in English. Far more students took AP exams in Spanish language, psychology, calculus, and history than in programming.
Insufficiencies in school can translate into a bigger problem on an economic level. Each year, U.S. companies need to fill almost 150,000 jobs related to computer science and mathematics, but colleges and universities only graduate about 100,000 students with degrees in those fields.

Largest open source company on Earth?
Quick question: which is the largest open source company on Earth? That's easy, right? It's clearly Red Hat. After all, the company pulls in over $1 billion each year selling services around open-source software like Linux and JBoss.
But as I've argued before, such a distinction fits a very old-school understanding of open source business. Back in 2009, I suggested that Google was the world's biggest open source company, given the copious quantities of code it contributes, not to mention its source code repository, inspiration of massive projects like Hadoop and other contributions. While some took exception to my classification of Google as an open source company, I still think it was accurate.
Except that Google is no longer the biggest open source company. Facebook is.

$ 1billion in Ipads delayed: LA DSB
Just a week after it began the first phase of putting iPads in the hands of all 640,000 students in the region, the Los Angeles school district already has a fight on its hands. In a matter of days, 300 children at Theodore Roosevelt High School managed to work around protective measures placed on the Apple tablets, giving them complete access to features -- including Facebook, Twitter and other apps -- that should otherwise have been blocked.

What do Colours Communicate
Did you know that colors communicate? The use of color in your blog design can be an essential part of how your personal brand is perceived. Color usage can either make or break your blog design, and I will show you how to choose your colors wisely by understanding what they communicate. When new visitors land on your blog, the first things they interpret are colors. Before they read a single character, their brain is registering colors which are subconsciously (or consciously) tied to emotions, states of mind, or [preconceived ideas]. If you do a poor job at putting together the colors in your blog design, it can be detrimental to the growth of your brand. - See more at: http://dustn.tv/what-colors-communicate/#sthash.SbjPxzMQ.dpuf

Killer Photoshop Basics
Adobe Photoshop is a very powerful and versatile image editing/graphics creation application that is the industry standard in its category. Though Photoshop’s interface is intuitive enough for an absolute beginner to learn basic image editing tasks such as cropping and resizing, to be able to fully master and utilize all of its tools takes a considerable amount of time.
If you’re interested in honing your Photoshop skills to create spectacular compositions, this is for you. In this article, you’ll find 35 basic Photoshop tutorials for getting started with Photoshop.

On being as Creative as Possible
"When you stumble into the shower shortly after you wake, you’re able to relax and, because you’re still tired, you’re able toreconnect with your subconscious. I’ve found this state to be so helpful in solving problems that I’ve had to devise ways to take notes on the shower wall."
Classical music is very rhythmic and, oddly enough, predictable. Classical also usually has a slower tempo, less than 60 beats per minute, whereas pop and jazz have unpredictable variances in tone and rhythm and often a much faster tempo....
Vinod Menon, Professor of Psychiatry and Behavioral Sciences at Stanford University’s School of Medicine, has written an interestingarticle on the subject. In the paper, Menon writes about music’s effect on the brain during an MRI. To simplify, the brain performs better when predictable patterns are in the music. During sudden breaks in the sound, the brain reacts to check on what’s happening. Your brain turns its attention back to the music, rather than stays on what you were concentrating on.

spying capabilities cover up to 75 percent of US internet traffic
The question of how much contact the NSA has with internet traffic throughout the US is being raised again, this time by the Wall Street Journal. Yesterday The Atlantic took issue with the security agency's mathematics and 1.6 percent claim, while the WSJ report looks more closely at its reach into telecommunications companies. The mishmash of codenamed programs are said to cover up to 75 percent of US internet traffic, although the amount actually stored and accessed is much smaller. The main difference between the calculations may be due to the difference between what ISPs -- handing over data under FISA orders -- carry, and what the NSA specifically requests. Its capabilities mean it can pull a lot more than just metadata, with access to the actual content of what's sent back and forth becoming even more troubling as privacy violations exposed by its own audits come to light.

Wickedest Lego thingy Ever
The newest addition to the grand list of Coolest Things Ever is being unveiled in New York today: the Lego X-Wing, the largest Lego model ever built.
The model of the classic Star Wars fighter being unveiled in Times Square has a wingspan of 44 feet and comes complete with R2-D2 and a full range of sound effects. It’s a super-duper-sized version ofStar Wars Lego starfighter set #9493 and was made with 5,335,200 Lego bricks. That, according to Lego, makes it the largest model ever built, eclipsing the Lego robot at the Mall of America by some 2 million bricks. This replica of the Rebel Alliance dogfighter is 42 times the size of the Lego version we’ve all built and a bit bigger than a real X-Wing. (Yes, yes, we know they’re not real. Just go with it.) The X-Wing Luke Skywalker and his fellow rebels flew was about 41 feet long, 2 feet shorter than this Lego masterpiece.

"When Cloud becomes the Platform"
But the other thing the new codec, known as ORBX.js, features is much, much more significant: it also enables steaming of desktop applications. An application (say, Microsoft Office) could be hosted on a company's server and then used by any employee who logs in to the application. It would not matter what operating system they were using (Windows, OS X or Linux) or even what platform (phone, tablet or desktop), because the browser would be the only thing that matters.
"This is not just remote desktop tech, or X11 reborn via JavaScript]," [blogged Mozilla Foundation CTO Brendan Eich, "Many local/remote hybrid computation schemes are at hand today, e.g., a game can do near-field computing in the browser on a beefy client while offloading lower [level of detail] work to the [game processing unit] cloud."

ISS leaves MS, goes Linux
All the computers on the International Space Station that used to run Windows XP now run Linux, reports Extreme Tech. The reason: Microsoft's OS just wasn't "stable and reliable" enough, according to the United Space Alliance, the spaceflight operations company that manages the hardware onboard the ISS in conjunction with NASA.

Open Sourcing Star Wars
"In a statement to Kotaku Australia, a Raven spokesperson said that the company is releasing the code “as a gift to the persistently loyal fanbase for our Jedi games and in memory of LucasArts.”
“We wish the best for all the talented people who were let go and hope they find good work in studios in the industry,” the statement read.
I did a little digging in the code, and some of the programmers’ comments make the files worth reading even for fans who can’t program.
After one huge pile of code involving lighting, one programmer writes “yes, this is completely ridiculous.” Another, commenting on a piece of code for a particle class in Jedi Outcast, noted “Man, this just seems so, like, uncool and stuff…”
In a piece of code related to camera control, one programmer sternly advises another, “we’re doing a cut, so just go to the new angles. none of this hifalutin lerping business.”
The source code for Jedi Outcast (my favorite Star Wars game) and Jedi Academy can be downloaded from SourceForge.net."

Cloud Security: How Secure is it?
To help you review your cloud security, Memset’s Kate Craig-Wood and the team have put together an Infographic to illustrate the main elements that you need to consider with regards to cloud computing’s safety, giving you the right questions to ask your potential providers and some tips on making your passwords much more secure.
Ultimately, the cloud is as safe as the way you set yourself up to be using it. Where is the data going to be held? Can you trust your staff that have access to all areas? Can your systems deal with Denial of Service attacks?

US: Recruiting 4000 Cyber Soldiers
Over the next few years the U.S. Cyber Command,
an army of 900 military personnel and civilians who monitor and defend
against cyber attacks, is set to grow by 4,000 cyber soldiers. The
command will expand its role in national defense by becoming a new kind
of fighting force, one that protects the Internet safety of the entire
country. As the expansion is implemented, Cybercom will be separated
into three teams:
- National Mission Forces
- Combat Mission Forces
- Cyber Protection Forces
