Job Interviews: 5 Questions Great Candidates Ask. 10 Programming Languages You Probably Never Heard Of. Okay – you know your variables and you know you declarations. You can write something more advanced than ‘Hello World’. But if you think that you know every programming logic in the world, think again.
Programming and logic co-exist…one is a Siamese twin of the other. But there are some very strange and bizarre programming languages which have turned logic on its head and have still managed to stay true to the science of communication with a computer. By the end of this post, you will be telling me – “You got to be kidding!” So, here’s the lineup of some esoteric programming languages and a few that actually do some work. Befunge Origin: Befunge was invented in 1993 by Chris Pressey. Described as an esoteric programming language, it is quite well described in Wikipedia. It is a two-dimensional, ASCII based language that is arranged in a ‘playfield’ (a two-dimensional grid).

Asus has taken the unusual step to send us a full Q&A document on its involvement with the Google Nexus 7 tablet, lifting the lid on the design and collaboration process with Google.
The document provides fascinating insight into the design process behind the Nexus 7 – incredibly the idea for the device was only born in January. "At CES 2012, the executives of Google and Asus met up to discuss future cooperative opportunities and the Nexus 7 was born," says Asus in the document. "From the concept in January, the target was to have the device ready in 4 months – a huge challenge, as a normal product design cycle is usually between 6 and 12 months. " Google sent engineers to Taiwan to work alongside the Asus team while Asus employees worked at various locations, including Google's Mountain View headquarters, to develop the device with Google in a 24-hour development cycle.
Design details Reducing power consumption Why no microSD and front camera? iPhone Touch Screen" Electronic devices can use lots of different methods to detect a person's input on a touch screen. Most of them use sensors and circuitry to monitor changes in a particular state. Many, including the iPhone, monitor changes in electrical current. Others monitor changes in the reflection of waves. These can be sound waves or beams of near-infrared light. A few systems use transducers to measure changes in vibration caused when your finger hits the screen's surface or cameras to monitor changes in light and shadow. The basic idea is pretty simple -- when you place your finger or a stylus on the screen, it changes the state that the device is monitoring. Most of the time, these systems are good at detecting the location of exactly one touch.
Many systems detect changes along an axis or in a specific direction instead of at each point on the screen. 3 Top Tips To Maintain Performance & Extend The Life Of Your SSD. For years, standard hard drives have been the speed limiting factor in overall system responsiveness. While hard drive size, RAM capacity, and CPU speed have grown almost exponentially, the spinning speed of a hard drive, i.e. the factor defining how fast it can be read, has increased only moderately in comparison. If you really want to give your computer a speed boost, try switching to a solid state drive, short SSD.
Unlike traditional magnetic hard disk drives, SSDs do not employ any moving mechanical components. Instead, they rely on NAND-based flash memory, which is much faster than HDDs for several reasons. However, Windows is not optimized to get the most out of SSDs, which come with their own weaknesses. If treated poorly, the speed of an SSD will degrade rapidly. 1. While defragging can speed up a regular HDD, it doesn’t do any good for an SSD, on the contrary. In Windows, make sure you have disabled scheduled disk defragmentation. 2. 3. TRIM is supported by Windows 7. 5 Of The World’s Most Famous And Most Influential White Hat Hackers. Hackers weren’t always known for being social misfits and Internet ninjas.
In fact, the word “hacker” was originally a positive term, indicating someone who had an extensive knowledge of computers and computer networks. It wasn’t until Hollywood got their hands on the word that it became synonymous with “criminal computer expert.” In this article, I’m going to jump back to the original definition and explore the world of “good hackers,” otherwise known as “white hat hackers.” If you’re looking to learn more about hackers of the evil and malicious variety, you may want to check out my previous article about world famous black hat hackers. Let’s take a look at five of the most influential computer experts that have helped shape the world to be what it is today. You may not know these people by name, but there’s a good chance you’ve heard of their work. Steve Wozniak Have you ever heard of Steve Jobs?

Digital Tools Flickr: Mark Anderson At a recent conference, professor Kristin Fontichiaro described watching a seven-year-old work his way through do-it-yourself resources online. Because he was comparing concrete items (e.g., his circuit versus that in the tutorial), and not abstract concepts, the student immediately understood what was a credible resource and what was not.
Although the task was about building a circuit, the student was also demonstrating meaningful, informed judgments about the quality of a given source, and understanding clearly what the impact of a quality resource would be on his final project. In the same way, using advanced operators when searching online can help students and makers zero in on exactly what they’re searching for. Another powerful operator for making and other pursuits comes from placing two dots between two numbers. Take a look at these search results for the query [makerfaire 2006..2010].

Sitting Can Reduce Your Life Expectancy [STUDY] If you're sitting at a desk reading this on a computer screen, take note: reducing sedentary behaviors like sitting and watching TV may have the potential to increase your life expectancy, even if you get regular exercise. According to a study published in the online journal BMJ Open if you sit for more than three hours a day, your life expectancy is lowered by about two years.
Throwing in a few hours of watching TV can add another 1.4 years. SEE ALSO: Fitness App Lets Charities Cash in on Your Exercise Routine That's enough to make someone stand up and take note! And similar research backs up these findings. A recent study by Australia’s Sax Institute says even with exercise, sitting down for several hours a day could bring you to an early grave.
Another study reported tracked 123,000 Americans and found the death rate for those who spent six or more hours a day sitting was 20% higher than for men who sat for three hours or less.

Finally, here's a working tutorial to disable the SEEN message from appearing on Facebook chat. It was easier earlier to pretend as if you were offline, if someone you don't like to chat with started a conversation. But after the SEEN message started appearing, people don't usually do so. Your friends know that you have seen the message but still have not replied to it and that might not be the wisest thing to do. Don't worry though, here's a solution to the problem to prevent your friends from knowing that you have already seen the message.

Literally, the output is the same as transmitting seven full Blu-ray movies per second. This works on the principle of electromagnetic waves that usually carry data are twisted into vortex beams.
Extreme Tech describes the process as: These twisted signals use orbital angular momentum (OAM) to cram much more data into a single stream. In current state-of-the-art transmission protocols (WiFi, LTE, COFDM), we only modulate the spin angular momentum (SAM) of radio waves, not the OAM. If you picture the Earth, SAM is our planet spinning on its axis, while OAM is our movement around the Sun. The combination of the two provides some amazing possibilities. Kalpana Sharma, EFYTIMES News Network. Google's Artificial Brain Learns to Find Cat Videos | Wired Science. By Liat Clark, Wired UK When computer scientists at Google’s mysterious X lab built a neural network of 16,000 computer processors with one billion connections and let it browse YouTube, it did what many web users might do — it began to look for cats.
[partner id=”wireduk”] The “brain” simulation was exposed to 10 million randomly selected YouTube video thumbnails over the course of three days and, after being presented with a list of 20,000 different items, it began to recognize pictures of cats using a “deep learning” algorithm. This was despite being fed no information on distinguishing features that might help identify one.
Picking up on the most commonly occurring images featured on YouTube, the system achieved 81.7 percent accuracy in detecting human faces, 76.7 percent accuracy when identifying human body parts and 74.8 percent accuracy when identifying cats. “The network is sensitive to high-level concepts such as cat faces and human bodies.

Patrick Lambert looks at the rash of stolen password exploits and how websites are trying to move beyond passwords only as a security check. We've talked a lot about passwords. In fact, they have been in the news like crazy in the past couple of weeks. First there was the LinkedIn incident, where over 6 million LinkedIn account names and unsalted SHA1 passwords were released. The fact that they were unsalted meant that it was trivial for hackers to recover all of the basic ones, and because they were hashed using SHA1, it meant that most nine-character or less passwords could be cracked inside of a few hours.
Then, we saw the same story repeat itself for various other companies like Last.fm and the popular matching site eHarmony. In each case, we see what happens when a hacker manages to get a hold of one of the most sensitive databases a company can hold on behalf of its users -- the account names and passwords. And these are fairly large sites, so it really can happen to anyone. 10 Things Online Data Collectors Won't Say.
