WiBit.net Java programming test, hands-on skills - BetterProgrammer.com Kurt Gödel's Ontological Argument Kurt Gödel is best known to mathematicians and the general public for his celebrated incompleteness theorems. Physicists also know his famous cosmological model in which time-like lines close back on themselves so that the distance past and the distant future are one and the same. What is less well known is the fact that Gödel has sketched a revised version of Anselm's traditional ontological argument for the existence of God. How does a mathematician get mixed up in the God-business? Gödel was a mystic, whose mathematical research exemplified a philosophical stance akin to the Neo-Platonics. In this respect, Gödel had as much in common with the medieval theologians and philosophers as the twentieth-century mathematicians who pioneered the theory of computation and modern computer science. Talking about proof theory often feels like discourse about God: When you talk about God, you have to discuss issues like "if God created the Universe, then who created God?"

What do High School students want from mobile tech? [Infographic] Based on statistics provided by PEW research, Nielsen, the National School Board Association and others, ASCD's infographic explores the connections between today's students, mobile learning and learning methods. The majority of Western schools attempt to ban the use of mobile devices; whereas a smaller number permit students to carry but not use the items. For many, suppressing such items becomes a losing battle -- as students continue to bring them, as well as parents preferring the option of being able to contact their children. According to the research, 63 percent of students attending schools carry their mobile devices despite the rules. Schools, in general, consider mobile devices a distraction and a way that more children experience bullying. Young people are becoming 'wired' and proficient with Internet use at an earlier age.

Learn Ruby with the Neo Ruby Koans How to build your own Linux distro Since Manchester University's Owen Le Blanc released MCC Interim Linux (generally agreed to have been the first Linux distribution), way back in 1992, there have been hundreds of ways to get the world's favourite free software operating system on to a computer. The diversity of alternatives reflects the diversity in the development community, with distros split along technical, functional, linguistic and even ideological lines. There have been large distros, tiny ones, bleeding edge and rock-solid stable distros. So with all the variety that's already out there, why would anyone want to create their own distro? Everyone's motivation is different, and for many that motivation isn't strong enough to make it past the first months of planning. You might look at the Ubuntu project and think you couldn't possibly compete, but you shouldn't forget that Ubuntu itself started life as a simple Debian fork with the goal of releasing stable versions more frequently than the Debian project.
Clone a Hard Drive Using an Ubuntu Live CD Whether you’re setting up multiple computers or doing a full backup, cloning hard drives is a common maintenance task. Don’t bother burning a new boot CD or paying for new software – you can do it easily with your Ubuntu Live CD. Not only can you do this with your Ubuntu Live CD, you can do it right out of the box – no additional software needed! The program we’ll use is called dd, and it’s included with pretty much all Linux distributions. dd is a utility used to do low-level copying – rather than working with files, it works directly on the raw data on a storage device. Note: dd gets a bad rap, because like many other Linux utilities, if misused it can be very destructive. Of course, the flip side of that is that dd is extremely powerful, and can do very complex tasks with little user effort. We’re going to take a small hard drive that we’ve been using and copy it to a new hard drive, which hasn’t been formatted yet. sudo fdisk –l Now the fun part: using dd.
