In this tutorial, we learn how to use salty hashes to keep passwords secure. A hash is stored in a database that is hashed with an algorithm, so not everyone can see exactly what your password is. When you type your password into a website, it doesn't actually register as words, it registers as a hash. This keeps your passwords secure so not everyone can see them. Salting is when you use random pits and attaching them to your regular hashes so not every password is the same. The salt is what ...
It's time to solve that Rubik's puzzle of yours, but how do you do it? Erno Rubik designed these three-dimensional mechanical puzzles to be precariously difficult, unless you know a little about mathematical algorithms, then it's just a matter of time and determination.

This video tutorial is for beginner puzzlers who are getting more advanced in their speedsolving of the Rubik's Cube. When solving the Rubiks Cube, there are these mathematical equations called algorithms, which I'm sure you already know. But wait... what do algorithms have to do with notation? Well, in an algorithm you have a sequence of letters that tell you which sides of the cube you want to turn. Each of the six sides of the Rubik's Cube are associated with a letter and a symbol that tel...

So, you can solve the Rubik's Cube, good for you, but what about the Square One? Erno Rubik is nothing compared to Karel Hršel and Vojtech Kopský, who invented the Square One puzzle, also called by its full title, "Back to Square One", or its shorter name of "Cube 21". It's shaped like a Rubik's Cube, but it's cut like a freak show, adding that layer of difficulty that challenges you.

This video shows you how to generate random numbers with decimals in Microsoft Excel.When generating random numbers you must have a lower and upper limit, so that your number will be generated between the two limits. For a number without decimals, you only have to use the "=randbetween" function. If you want to use decimals, you will have to use a different but similar function. Start by typing "=rand()". Next, you multiply this by the difference between the limits and add the lower limit. Fo...
You have a Rubik's Cube, maybe your mother gave it to you for your birthday, maybe you actually bought it for yourself, or maybe you just found that colorful puzzle cube in the gutter, but either way... you don't know how to solve it.
Passwords are everywhere. We use them to unlock phones, computers, websites, encrypted disks, encrypted files... the list just goes on and on. Savvy users will already have a password manager of some sort that can generate a very strong password on a per site basis. However, these password managers also require a password. Not only that, it has to be something memorable.

In order to solve a 5x5 Rubik's Professor Cube, you'll need to, of course, already know how to solve a 3x3 Rubiks Cube. First, you'll need to get the centers solved first, then you pair the edges (with the algorithm 2D*, R, F', U, R', F, D'*), and solve parity (with the algorithm 2R*, 2B, 2U, L*, 2U, R'*, 2U, R*, 2U, 2F, R*, 2F, L'*, 2B, 2R*), then you continue to solve it just like a normal 3x3 cube until it looks brand new, out of the plastic box.
--with algorithms! If you know nothing on the Rubik's Cube, then you'll probably still know nothing on the Rubik's Cube after watching this, because you should really start off somewhere smaller. This is for those cubers who know a little bit about solving it already. Watch both parts to see how to optimally use the algorithms to solve.
When we are building programs that communicate over a network, how can we keep our data private? The last thing we want is some other lousy hacker sniffing our packets, so how do we stop them? The easy answer: encryption. However, this is a very wide-ranging answer. Today we're going to look specifically at how to encrypt data in Python with dynamically generated encryption keys using what is known as the Diffie-Hellman key exchange.
