Hydrazine sulfate has many uses, but most notably, it's been used under the trade name of Sehydrin, a treatment for anorexia, cachexia and some even think cancer. But for we DIY chemists, it's useful for something entirely different— as a substitute for the more dangerous pure liquid hydrazine in chemical reactions. NurdRage shows you how to make it via some hypochlorite and the Ketazine process.
In this video from TheCurrentCustom she teaches how to enhance your breasts. First she says you need to measure your breasts to figure out the right kind of bra for you. Take the measuring tape below your bust, and wrap around back, and then measure right above your bust. Round down to the nearest even number if you get an odd number. Then measure your bust size by wrapping the tape measure around the largest part of your bust, typically where your nipples are. Then subtract the bust size fro...

Footwork is probably the most important part of tennis. Unfortunately, it is also one of the most underrated areas of the sport. Learning to move around the tennis court correctly is EXTREMELY important. Correct footwork lets you use correct stroke mechanics when you hit. Correct footwork is what typically sets advanced tennis players apart from everyone else.
This video explains how the amount of shoulder rotation you get during a windshield wiper forehand can differ from a classic forehand. After you hit the tennis ball, you typically have to rotate a little bit more than you otherwise would on the windshield wiper. There are a number of reasons for this, but in this video we keep our focus relatively narrow.
How to generate a tag cloud - a collection of tags that displays keywords in different sizes based on their frequency of use - using PHP.
QR codes are so handy. Nowadays, all you have to do to scan one is open your phone's camera app and tap a button. But creating one is a different story — online QR code generators aren't always trustworthy, and most phones don't have a built-in feature for it. Thankfully, Google Chrome now does.
Apple's password manager, iCloud Keychain, lets you securely save important login credentials for apps, websites, and services that sync up across all of your Apple devices — iPhone, iPad, iPod touch, and Mac. One of its biggest highlights is that it can create strong passwords for you. Unfortunately, it doesn't always work, and in those cases, there are other ways to generate random, strong passwords.

No matter how you cut it, slides are tons of fun. There are all types of slides, and while some are big and scary, many are not. Regardless of whether you are having a blast on some mellow slides or trying to set a world speed record on something large there are a few techniques which will help you ensure success. Watch below as Shane helps us out with some basic slide technique:

Snapchat popularized personalized stickers for social media and messaging with Bitmoji, followed by walled-garden versions from Apple with Memojis and Samsung with AR Emojis. Even Google has gotten into the game, integrating an emoji generator for Gboard.
Users are often the weakest link when probing for vulnerabilities, and it's no surprise they can be easily fooled. One way to do this is called clickjacking. This type of attack tricks the victim into clicking something they didn't mean to click, something under the attacker's control. Burp Suite contains a useful tool called Clickbandit to generate a clickjacking attack automatically.
Beginners learning brute-forcing attacks against WPA handshakes are often let down by the limitations of default wordlists like RockYou based on stolen passwords. The science of brute-forcing goes beyond using these default lists, allowing us to be more efficient by making customized wordlists. Using the Mentalist, we can generate millions of likely passwords based on details about the target.
While other devices are moving away from fingerprint scanners (cough, iPhone X), for many, a fingerprint scanner provides the best balance between security and speed.
