Gamification About the Course Gamification is the application of digital game design techniques to non-game contexts, such as business, education, and social impact challenges. Video games are the dominant entertainment form of modern times because they powerfully motivate behavior. Over the past few years, gamification adoption has skyrocketed. Game thinking means more than dropping in badges and leaderboards to make an activity fun or addicting. Subtitles forall video lectures available in: English, Russian (provided by Digital October), Turkish (Koc University), and Ukrainian (provided by Bionic University) Course Syllabus The course is divided into 12 units. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. Recommended Background This course is designed as an introduction to gamification as a business practice. Suggested Readings The course is designed to be self-contained. Course Format The class will consist of video lectures, which are between 7 and 12 minutes in length. Yes. • Who should take this course?

The Cryptopals Crypto Challenges Secret Language: Cryptography & Secret Codes Ron Hipschman When you were a kid, did you have a "Captain Midnight" decoder ring? With it, you could send messages to a friends that no one else could read. Or perhaps you remember using special symbols to write notes to your "squeeze" in class. If the note was intercepted , your teacher, could learn nothing about your romance. In more serious uses, codes and ciphers are used by our military and diplomatic forces to keep confidential information from unauthorized eyes. The study of enciphering and encoding (on the sending end), and deciphering and decoding (on the receiving end) is called cryptography from the Greek (kryptos), or hidden and (graphia), or writing. For a cipher to be useful, several things must be known at both the sending and receiving ends. The algorithm or method used to encipher the original message (known as the plaintext).The key used with the algorithm to allow the plaintext to be both enciphered and deciphered.The period or time during which the key is valid.

Understanding Einstein: The Special Theory of Relativity About the Course In this course we will seek to “understand Einstein,” especially focusing on the special theory of relativity that Albert Einstein, as a 26-year-old patent clerk, introduced in his so-called “miracle year” of 1905. Our goal will be to go behind the myth-making and beyond the popularized presentations of relativity in order to gain a deeper understanding of both Einstein the person and the concepts, predictions, and strange paradoxes of his theory. Some of the questions we will address include: How did Einstein come up with his ideas? What was the nature of his genius? Students may choose one of three approaches to the course: a more quantitative approach, a more qualitative approach, or an auditing approach. Course Syllabus Week One (Einstein in Context): Einstein quotes of the week; a thought experiment involving relativity; physics and Einstein circa 1900. Week Six (Breaking the Spacetime Speed Limit?) Recommended Background No prior knowledge is required. Course Format

pFarb/awesome-crypto-papers: A curated list of cryptography papers, articles, tutorials and howtos. Code Breaking Learn to Program: The Fundamentals About the Course A computer program is a set of instructions for a computer to follow, just as a recipe is a set of instructions for a chef. Laptops, kitchen appliances, MP3 players, and many other electronic devices all run computer programs. Recommended Background This course is intended for people who have never programmed before. Suggested Readings This online course is intended to be self-contained, but if you want additional reading material you will find that Practical Programming (2nd edition): An Introduction to Computer Science Using Python 3 matches the course material closely. Course Format The class consists of 1 to 2 hours of lecture each week, which are made up of videos that are generally shorter than 10 minutes each.

Quickstart · EmpireProject/Empire Wiki Initial Setup Run the ./setup/install.sh script. This will install the few dependencies and run the ./setup/setup_database.py script. The setup_database.py file contains various setting that you can manually modify, and then initializes the . Running . Main Menu Once you hit the main menu, you'll see the number of active agents, listeners, and loaded modules. The help command should work for all menus, and almost everything that can be tab-completable is (menu commands, agent names, local file paths where relevant, etc.). You can ctrl+C to rage quit at any point. Listeners 101 The first thing you need to do it set up a local listener. The info command will display the currently configured listener options. Set optional and WorkingHours, KillDate, DefaultDelay, and DefaultJitter for the listener, as well as whatever name you want it to be referred to as. Stagers 101 The staging process is described here. Empire implements various stagers in a modular format in *. Agents 101 Modules 101 Scripts

Cryptology The word Cryptology comes from the Greek word kryptos, which means hidden and logos, which means word. It is the branch of science that deals with secret communications. To keep communications secret, it is necessary to use a code, a cipher, or both. A code is a system of symbols representing letters, numbers or words. For example, you could create a code that might represent the following words as: The=01, in=02, Spain=03, mainly=04, rain=05, falls=06, Germany=07, drops=08, on=09, plain=10 The encoded message might read: When you decoded the message by replacing the number with the matching word you get: The rain in Spain falls mainly on the plain. Without the table showing what words go with which numbers, it would be very hard to guess the meaning of the encoded message. Codes are not used only to protect secret information. The table that contains the translation of the words to the code is often in the form of a book and is referred to as a codebook. Ciphers Meet you at the corner

Greek and Roman Mythology About the Course Myths are traditional stories that have endured over a long time. Some of them have to do with events of great importance, such as the founding of a nation.
