In Linux, all password hashes are normally stored using the MD5 hashing algorithm in the /etc/shadow file, but MD5 is algorithmically weak due to collision vulnerabilities. The new recommended standard are the higher level SHA-2 hashing algorithms, SHA256 or SHA512. As a friend pointed out to me, Ubuntu is currently the only distro implementing SHA-2 as the default. With SHA-2, your passwords take an unreasonably larger amount of time to calculate. This will greatly decrease how many password...
There’s nothing like a great horror movie to really get the adrenaline pumping during the Halloween season. I don't know about you, but the sight of blood dripping into a pool of even more blood creeps me out, so you can imagine my reaction to harrowing creatures that go bump in the night and rip people's faces off. It's intense, but I love it.
Cinderella, Little Red Riding Hood and Sleeping Beauty are some of the most horrific fairy tales ever written, but over the course of nearly 200 years they've become watered down and sugar coated for innocent children everywhere. The original tales by the Brothers Grimm are virtually opposites of how we know them today, because they were never really intended for unsullied youngsters. The folk tales came from storytellers across the German countryside, recounting the terrors they've heard ove...
Welcome to Minecraft World! Check out our advanced tutorials and come play on our free server. One of the newest features to be added to Minecraft is the hunger bar. Since the final 1.8 update, players go hungry over time if they don't replenish themselves. Hunger is also determined by the level of activity, meaning the more you run about or kill monsters, the hungrier your character becomes.
If you love Angry Birds, why not dress up as one for Halloween? This makeup tutorial will show you how to use makeup to look like the red bird from Angry Birds. You'll need several different colors of makeup pencils in order to get the look right. Once you apply it, your Angry Birds costume will be the hit of the Halloween party.
If you thought the last post on Two Circle Wobblers was wild, then wait until you see what happens when you build wobblers out of two half circles or two ellipses. In both of these cases, the center of gravity still remains constant in the vertical direction, allowing them to roll down the slightest of inclines or even travel a significant distance on a level surface if given a push or even when blown on.
This Halloween, give your nails that special seasonal touch with a cool pumpkin design on them. If you're going for a full set, carved jack-o-lantern nails are a great idea because you can paint different teeth onto each one.
This is one concept that I would love to see sweep the urban world. One thing that strikes me every time I visit a major city is how far away they are from anything that is truly alive. Not only is the air dirty, but everyone must buy their produce from the grocery store. If those trucks were to stop coming for any reason, most people, if not everyone, would die of starvation. While this house is covered with ornamental plants, I would love to see this same concept applied to edible plants an...
This article will teach you how to make an iPod video projector for about $6 (depending on what materials you have) that works pretty well. First off, you need to gather your materials. I had everything except the magnifying glass, which I bought for $3.
Decreasing on a Circular Needle is as simple as decreasing on a straight needle. You can still do it both ways. Either K 2 tog or K, slip, psso. You will need to know how to decrease on a circular needle when you make hats or purses. If t don't know how, see the bottom of the page for instructions.
Since its inception, Google+ users have been a loud, vocal bunch, and they've made their displeasure known about many issues, especially on the lack of support for pseudonyms, Google Apps, and brand pages. It's been especially galling for many Google loyalists, who found their Google+ profiles suspended, when they ended up violating the Google+ "common name" policy.

eBooks are an amazing thing, especially with Amazon's Kindle. What's irrtating about eBooks as that you have an infinite selection of books at your fingertips, but they all cost so much! Well, as always, Null Byte has a trick up our sleeves for nabbing free ebooks from Google.
Dungeon Defenders is the most exciting craft game on the Fall 2011 release schedule. I got a chance to play it at PAX in August and interviewed developers Trendy Entertainment last month. After more than a year of publishing difficulty and delay, the game finally came out on PSN, XBLA and Steam. I put about 20 hours into the XBLA version over the past weekend, beating all the campaign maps and racking up a huge pile of in-game money. It is not a perfect game. But it is a huge, challenging, an...
I took this picture in India at a special holiday- "The wedding of Shiva and Parvati". Everybody put on their best clothes and happy faces. Bananas are launched in the air to pray for good fortune and end up as delicious snacks for the monkeys after they rain down from a yellow sky.
Cross-Site Request Forgery (CSRF, pronounce "sea-surf") is a common web exploit. However, for unknown reasons it's not used very often. It plays on a given website's trust in a web browser by executing another website's form action, for example, sending money to another person. It's usually placed in abnormal places like HTML image tags.
Leaving your wireless router at its default settings is a bad idea. The sad thing is, most people still do it. Once they've penetrated your network, hackers will change your router settings so they'll have an easy way back in. This allows them to change your network into a shell or proxy so they can forward their traffic anonymously through you when committing other dirty deeds.

Your IP (Internet Protocol) address is your unique ID on the internet. It's synonymous with your home address. Anyone in the world can contact your computer through its IP address, and send a retrieve information with it.
It's a question I've been pondering a lot lately. Technically, children under the age of 13 are not allowed to join Facebook. But according to a Consumer Reports in May, 7.5 million children 12 and younger are already on the site. Currently, federal law prohibits websites from collecting personal data from children without parental permission. The Children's Online Privacy Protection Act, or COPPA, as it is more commonly known, has been in effect since 1998, but has not been updated since.
Mugshots aren't just for criminals anymore. In the world of competitive Scrabble, no one's safe from the lens of photojournalist Roger Cullman. For the last couple years, Cullman has been hitting up the Scrabble circuit with hopes of immortalizing some of the world's best Scrabble players in headshot pictures of them holding racks with their surnames spelled out in Scrabble tiles.
One of my favorite simple projects is building two circle wobblers. I love how such a simple object amazes with its motion. The two circle wobbler is an object made out of two circles connected to each other in such a way that the center of mass of the object doesn't move up or down as it rolls. This means that it will roll very easily down a slight incline. It will also roll for a significant distance on a level surface if you start it by giving it a small push or even by blowing on it!
Cheating. It happens everywhere. From scientists faking human ears on mice, to Hollywood thirty-somethings cheating on their quadragenarian wives, to chess players accusing supercomputers of fraud. There's no game or profession out there that doesn't have a cheater or two, but the bigger nuisance is probably those people who accuse others of cheating.

Aesthetic Houses: What are they? If you've played Minecraft for some time now, you most surely know how hard it is to build a great looking house to live in, that meets both your vision of your dream house and expectations for functionality. This brings us to the definition: in terms of Minecraft, its a structure that dosen't compromise beauty and appeal for functionality.
This is a great way to repurpose your old covers! Tired of your old iPhone cover? Rather than spend $30 on a new one, why not just paint the old one until it suits you? It's way less expensive, and better on the environment!

It's Monday, time to highlight some of the community submissions posted to the Math Craft corkboard. One of these posts inspired me so much, I think it merits a closer look. Today, I present a "simple" method for making a golden spiral using just a straight edge, a compass, and a template, inspired by RJ Ellicock's golden ratio post.

If you’re planning to hold a party this October, what better event to model your event after than Oktoberfest? The German beer festival began in Bavaria, Germany in 1810 to celebrate a royal marriage. Since then, it has been celebrated annually by millions of attendees these past decades and has spread throughout the world. Of course, Oktoberfest would not come to be without the beer.
It’s been a pretty big week for Google, and Google+ itself. There were a number of articles proclaiming the end of Google+, because allegedly traffic dropped over 60% after it opened to the public. Then +Steve Yegge accidentally posted a long rant on Google+ itself, which was originally meant only for Google employees and colleagues to see. Interestingly enough, the most inflammatory content wasn’t actually about Google itself, but about the horrible work environment at Amazon. The accidental...

I am completely fascinated with pedal transportation. Many of us have pedalable commutes that we end up driving just because we don't like bikes. There's a whole wave of do-it-yourself pedal vehicles, from the Hennepin Crawler down to vehicles like this one.
It's still a work in progress, says Notch but here it is, a proper video of dragons in Minecraft. Notch also somewhat hinted that they would be compatible in SMP!! Time to go make a band of dragon slayers!
There's only a few week left until costumes and candy take over the streets, which means they'll be more and more seven-letter words in the Scrabble Bingo of the Days that relate to the Fall season, horror movies, and of course… Halloween. Below you'll find bingo words relevant such films as Halloween, Children of the Corn and The Wicker Man.
