The guitar is a double-edged sword. I've played all my life, and though I love the act of guitar playing, there are quite a few people I could live with never hearing play again—ever.
Brushing your teeth is a necessity. You don't want to walk around with yellow teeth and stinky breath, and it's common courtesy to those around you to care about your personal hygiene at least that much.
We've all been there. You wake up early, hungry for breakfast, but not just any breakfast will do. You want bacon and eggs. So, you blindly stumble into your kitchen, underwear-clad, and begin fumbling about with pots and pans. After a few minutes, you fill your pan with delicious and smokey rashers and turn the heat on. Everything seems okay... until the bacon actually starts to cook. With a splat, burning hot grease flies out of the pan and bombards your skin, causing intense pain and great...
There are loads of reasons for somebody to want to recover a Windows password, and there are lots of different ways of doing it. My favorite of all of these ways is to use a piece of software called Ophcrack because:
In this article, I'll be explaining the basics of how microcontrollers work, physically and virtually. First off, microcontrollers are no simple thing, so don't be discouraged if you find it mind-boggling! The world of microcontrollers is fascinating, engaging, and an awesome hobby; it never gets boring. I'll be focusing more on I/O and analog based microcontrollers, such as those running Arduino, and using Atmel chips as examples (these are most commonly available, and easy to program).
We've all seen the breathtaking, colorful photos of the Eagle, Egg and Cat's Eye Nebulae. You may not recognize them by name, but you've seen them, whether in astronomy textbooks, magazines, websites, album covers, or tee shirts. They are some of the most striking photographs ever taken from the Hubble Space Telescope (HST).
Oh, boy. A stopped-up drain. It'll inevitably happen with any home plumbing system and your kitchen sink is no exception. That clog won't go away on its own and will require immediate attention to keep any standing water from rising. But you don't have to resort to calling an expensive plumber or using a bottle of hazardous chemicals. Using simple kitchen staples or common household objects, as well as some determination, you can unclog your kitchen sink on your own without paying a dime.

SCRABBLE. To some it's just a game, but to me it's life or death. Well, not really, but it feels that way anyway. On a normal weekend, a game becomes much like Jon Thomas' "friendly game of death Scrabble."
The best way to get into recycling is make it simple. Recycling newspapers is a great way to start your efforts to go green. It is one of the most common paper products in your home that can be recycled. The hard part is keeping the papers from becoming a big mess while you store them. Bundling the papers and tying them up can be very hard. An easy solution for that problem is to put two pieces of string that are long enough to wrap around the bundle of papers in a wagon. Lay them in the wago...
If you're racing for time or taking a leisurely ride by the beach there's little that's more annoying than a squeaking sound every rotation of a wheel. Don't let a squeaky break ruin your biking fun when those brakes can be as good as new in no time.
A CNC router machine is probably the most useful tool a hobbyist can own, but the price for a CNC machine on the market is way more than the average hobbyist is willing to spend. You can build your own CNC with very basic tools, little knowledge of machinery, mechanics, or electronics, but be warned, these machines are inherently dangerous, so wear the proper protection and use common sense. At the very least, read the instructions and precautions on every tool you use.

These days, most images we post online or share with others come from our smartphones. Whenever personal data is in them, such as debit card numbers, addresses, phone numbers, passwords, and other sensitive information, it's easy to jump into your iPhone's markup tools to black out the text before sharing. But a digital marker may not hide everything.
Fireworks are the best part about the Fourth of July and other celebrations, but they can easily cause accidental injuries. It's both safer and more fun to set them off remotely, so we'll hack some standard fireworks with nichrome wire, a relay, and an Arduino to ignite remotely over Wi-Fi using any smartphone or computer.
The most common Wi-Fi jamming attacks leverage deauthentication and disassociation packets to attack networks. This allows a low-cost ESP8266-based device programmed in Arduino to detect and classify Wi-Fi denial-of-service attacks by lighting a different color LED for each type of packet. The pattern of these colors can also allow us to fingerprint the tool being used to attack the network.
The easiest way around a security policy is to find users who don't follow it. The Have I Been Pwned database identifies accounts with information breached by major third parties like Yahoo and LinkedIn. With Maltego, hackers can locate breached accounts created using company email addresses, potentially giving attackers access to a company account if the employee reuses a compromised password.

This is a very common injury seen in contact sports. Learn how to diagnose and treat a dislocated shoulder in this medical how-to video.

While there's an art to surviving the all-nighter, there's also an art to staying awake throughout the day when you're operating on little to no sleep. In 1964, the record for sleep deprivation was set by 17-year-old Randy Gardner, who stayed awake for an incredible 264 hours and 12 minutes. Now while we're not out to challenge Randy for his title, we can certainly look to him for inspiration in beating back our own fatigue.
