In mathematics, a knot is a closed circle in a three-dimensional space that crosses itself multiple times. Since it is closed, it has no ends to tie, meaning you can't actually create such a knot. However, if you tie the ends together after you create a knot in the standard way, you will have something that is close to the mathematical description. In this post, we will explore the creation of mathematical knot sculputures using copper tubing and solid solder wire.
Permanently deleting files is something that a lot of people aren't aware of. Actually, most people think that once a file is deleted, it is gone forever. This is not the case. Hard drives write to the disk via magnetic charges, positive and negative correlate to 1s and 0s for binary. This is then interpreted into information for the computer to use and access.
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...
The dreaded moment you hope never happens—someone has stolen your laptop. You could have private information, pictures, or even private information belonging to the company you work for, all lost forever. It can cause you pain, money, or even a job.
Like the recent XSS 0day exploit found in the Mac and Windows versions of Skype, a similar one has been found in the Skype app for iPhone. The vulnerability allows an attacker to send a message that contains malicious JavaScript code in the "Name" parameter. This code can steal your phonebook, crash the app, and potentially do a lot worse. The URI scheme is improperly identified for the web-kit browser. Instead of going to a blank browser page, it defaults to "file://". The code could steal a...
I was going to update the first list of 15 Brilliant Google+ Female Photographers to Circle, but then I kept coming across so many amazing women that I decided to create another post highlighting their work.

Not only is this little rat a great step up for people who feed reptiles it is virtually odorless and that is definately a plus for those who would like to have a pet rat or mouse they can keep inside the house and not spend a fortune in bedding or spend a lot of time cleaning to keep the rodent odor down.
What's the Difference Between Ales and Lagers People often ask me, "Nick, what is the difference between Ales and Lagers?" Well, as you may or may not know, there are two types of beers -Ales & Lagers. All beers are made from the basic combination of water, hops, malts, and yeast. However, Ales have been around for thousands of years longer than lagers. So, what makes lagers and ales unique? Here are a few steps to figure out the process:
What's so great about Mineral Makeup anyway? Mineral Makeup is by nature, a long-wear, water-resistant product. This means less touch-ups and lasting coverage-even in the summer! High quality minerals are lightweight, inorganic and non-comedgenic. "Inorganic" means that bacteria and microbes cannot live in the makeup. This means less clogged pores, and no infections leading to nasty breakouts!
What's more important in maintaining a healthy body weight? Eating healthy food or simply reducing your calorie intake?

Scroll to the bottom to see what the bee feature is good for! The bees are here! Farmville users have been requesting bees since the beginning of the game and a year later, they have finally given them to us! This feature is more complex than just an item though, so check back here for more information about them as I figure it out :)
There is a wonderful site that just launched with the youth sports community in mind. The site is http://YouthSportTravel.com , a collaboration of youth sports coaches and a major online travel brand. They offer arguably the best prices on hotel and motel rooms anywhere. For proof, I tested a number of locations with www.hotel.com, Expedia and Travelocity in comparison with YouthSportTravel and in each case; YouthSportTravel was equal to or cheaper than the competition. But this is not all th...

With the new privacy settings updates that are rolling out this week there are a couple glitches. Currently people's posts are being set to 'only me'. You need to manually change this before anyone will be able to see your status updates or game posts. I'm confident facebook will fix this soon, but until then here's how to do it.
Make My Mondays Meatless! One day a week join in on cutting out the meat!

There is a thread on Neogaf that talks about playing the game in first person mode instead of the default 3rd person point of view.
Be honest about your pet's ability to travel. If your pet is very young or old, or is ill, pregnant, or recovering from surgery, it may be better for all concerned to look into a pet sitter or kennel rather than take a chance on injuring your pet by taking it with you. If you are in doubt, ask your veterinarian. If your pet has not traveled before, try a short overnight or weekend trip first.

The task of getting clear skin is easy with the simple tips put forth in this video. While one can simply wash their face with soap and water, this does little to help with the ever-present blackhead. To get rid of them for good, you must first start with the right products, which are fully explained in this video. For best results, it is recommended that you use not only an exfoliating scrub, but also masks and intensive medicated blackhead treatments, if necessary. Get rid of blackheads for...

Many windows users, if not all, run into a virus infection once in a while. This is unavoidable when using Microsoft's operating system. Without digressing too much, the fact that Windows is such a popular OS with no controlled software sources makes it easy for viruses and malware to spread. And while there's a plethora of antivirus tools for Windows, sometimes infections (such as certain scareware) can disable the install and/or use of antivirus systems and render your OS unusable until cle...
The Elder Scrolls V: Skyrim set off a bang in the video game world this month. It will likely be video game of the year a few times over. Skyrim is another part to a series set in the fantasy world of Tamriel, a world filled with mystical creatures, folklore, and even its own history. It's quite the beatuiful and immersive experience. If you have not picked up the game yet, please do (my fiancée even plays!). Also, make sure to buy it new, so the hard working coders at Bethesda get the money ...
+Nik Cubrilovic discovered last week that Facebook could track your web activities even after you logged out of your Facebook account. After some blatant denials from Facebook spokespeople, Facebook decided to fix the logout issue, but not before +Michael Arrington, on his new Uncrunched blog, made a concise post revealing Facebook's dishonesty: Facebook submitted a patent application for "tracking information about the activities of users of a social networking system while on another domain...
I know it seems a little redundant to post this when I've already posted a video, but it is kind of hard to get more than a vague idea from the video alone. I hope this sheds a little more light on the subject. I'm sure it also seems like I'm beating this idea to death, but this one concept opens doors to further innovation. After I finish this article, I'm going to put another one up that shows a hinged, raised bed house and talk about some amazing things you can do from there.
Camera manufacturers release new versions of the same cameras, mostly point-and-shoot models, as frequently as Detroit's auto industry upgrades minivans. They also add new lenses regularly, upgrading previous models with adjusted zoom ranges or the image stabilization feature. The same goes for tripods, portable flashes and even camera bags.

Written by JD Coverly of WonderHowTo World, LoadSave:We've spent the last week with Sprint's new phone, the HTC Evo 4G. Specification wise, it's better than Verizon's Incredible and T-Mobile's HD2. Apple has unveiled the new version of their phone this week and thankfully it's debatable as to which phone is better. The iPhone has better battery life and a more robust App store, but it suffers from a smaller screen, smaller camera resolution, no HDMI out, face talk only on wi-fi networks, and ...
