Free online courses from Microsoft @edX.org

Be passionate and bold. Always keep learning. You stop doing useful things if you don’t learn.” – Satya Nadella, CEO, Microsoft

We live in a mobile-first and cloud-first world. Computing is ubiquitous, and experiences span devices and exhibit ambient intelligence. Billions of sensors, screens and devices – in conference rooms, living rooms, cities, cars, phones, PCs – are forming a vast network and streams of data that simply disappear into the background of our lives. This computing power will digitize nearly everything around us, and will derive insights from all of the data being generated by interactions among people and between people and machines. We are moving from a world where computing power was scarce to a place where it now is almost limitless, and where the true scarce commodity is increasingly human attention.

In this new connected world, we believe technology creates opportunity, and our edX courses are designed to provide you with the core development skills needed to be successful in the cloud-first, mobile-first world.

Our edX courses, taught by Microsoft experts, let you learn through hands-on experience with broad reach, cutting-edge technologies in areas including cloud services, mobile development, and data sciences. Whether you’re a student or a seasoned technologist, we can empower you to build innovative applications, services, and experiences on the Microsoft platform that will help you make a meaningful impact in today’s interconnected world.

Is Microsoft Edge safer than Google Chrome or Mozilla Firefox?

“Chrome set the bar high. Firefox couldn’t match it. Edge jumped right over it.” – VentureBeat

“…unlike Chrome, Edge doesn’t hog so much of computer’s power. On a Web-browsing battery test, the Dell XPS 13 lasted an hour longer with Edge than with Chrome. When streaming Netflix, it lasted two full hours longer.” – Wall Street Journal

According to NSS Labs. Microsoft Edge blocks more phishing sites and socially engineered malware than Google Chrome or Mozilla Firefox. See details here

Not only is Microsoft Edge safer, it’s faster. See more

(New) Windows 10 coming April 11th, 2017 as a free update

Recently, if you have accessed the Windows Update you might have noticed the following:

Good news! The Windows 10 Creators Update is on its way. Want to be one of the first to get it?

Yes, show me how

Yusuf Mehdi, Microsoft’s Corporate Vice President (Windows and Devices Group) on March 29th, 2017 through Windows 10 Blog announced the following:

Dona Sarkar, Microsoft’s Software Engineer (Windows and Devices Group), on March 20th, 2017 through Windows 10 Insider Blog announced the Windows 10 Insider Preview Build 15063 for PC and Mobile. Windows Insiders in the Release Preview ring will be helping test the update path from the Windows 10 Anniversary Update (Build 14393) that customers will be taking.

Here are just a few of the new features coming in the Windows 10 Creators Update:

  • 3D for Everyone and enabling mixed reality
  • Watch, participate, chat and interact in real-time with Beam
  • Microsoft Edge is faster and safer with better browsing and entertainment
  • From sleeping better to easily managing your children’s screen time

(Short) History of Cryptography

Cryptography is typically bypassed, not penetrated.” Adi Shamir

Cryptography is one of the oldest fields of technical study we can find records of, going back at least 4,000 years. Cryptography probably began in or around 2000 B.C. in Egypt, where hieroglyphics were used to decorate the tombs of deceased rulers and kings. These hieroglyphics told the story of the life of the king and proclaimed the great acts of his life. The ancient Chinese used the ideographic nature of their language to hide the meaning of words. Messages were often transformed into ideographs for privacy, but no substantial use in early Chinese military conquests is apparent. In India, secret writing was apparently more advanced, and the government used secret codes to communicate with a network of spies spread throughout the country. The cryptographic history of Mesopotamia was similar to that of Egypt, in that cuneiforms were used to encipher text. In the famous Greek drama the ‘Iliad’, cryptography was used when Bellerophon was sent to the king with a secret tablet which told the king to have him put to death. The Spartans used a system which consisted of a thin sheet of papyrus wrapped around a staff (now called a “staff cipher”). Another Greek method was developed by Polybius (now called the “Polybius Square”). Julius Caesar used a system of cryptography (i.e. the ‘Caesar Cipher’) which shifted each letter 2 places further through the alphabet (e.g. Y shifts to A, R shifts to T, etc.). The Arabs were the first to make significant advances in cryptanalysis. An Arabic author, Qalqashandi, wrote down a technique for solving ciphers which is still used today. [Cohen, 1990-1995]

During the Middle Ages, cryptography started to progress. Venice created an elaborate organization in 1452 with the sole purpose of dealing with cryptography. Leon Battista Alberti is known as “The Father of Western Cryptology” in part because of his development of polyalphabetic substitution. The next major step was taken in 1518, by Trithemius, a German monk who had a deep interest in the occult. In 1553, Giovan Batista Belaso extended this technique by choosing a keyword that is written above the plaintext, in a letter to letter correspondence. In 1628, a Frenchman named Antoine Rossignol helped his army defeat the Huguenots by decoding a captured message. By the 1700’s, “Black Chambers” were common in Europe, one of the most renown being that in Vienna. The father of American cryptology is James Lovell. He was loyal to the colonies, and solved many British ciphers, some which led to Revolutionary victories. The ‘wheel cipher’ was invented by Thomas Jefferson around 1795, and although he never did very much with it, a very similar system was still in use by the US navy only a few years ago. In 1817, Colonel Decius Wadsworth developed a set of two disks, one inside the other, where the outer disk had the 26 letters of the alphabet, and the numbers 2-8, and the inner disk had only the 26 letters. In 1844, the development of cryptography was dramatically altered by the invention of the telegraph. The ‘Playfair’ system was invented by Charles Wheatstone and Lyon Playfair in 1854, and was the first system that used pairs of symbols for encryption. In 1859, Pliny Earle Chase, developed what is known as the fractionating or tomographic cipher. A two digit number was assigned to each character of plaintext by means of a table. Kasiski developed a cryptanalysis method in 1863 which broke almost every existing cipher of that time. The method was to find repetitions of strings of characters in the ciphertext. Just as the telegraph changed cryptography in 1844, the radio changed cryptography in 1895. In 1917, the Americans formed the cryptographic organization MI-8. It’s director was Herbert Osborne Yardley. [Cohen, 1990-1995]

The use of cryptographic machines dramatically changed the nature of cryptography and cryptanalysis. The next major advance in electromechanical cryptography was the invention of the rotor. During WW2, the neutral country Sweden had one of the most effective cryptanalysis departments in the world. In 1948, Shannon published “A Communications Theory of Secrecy Systems.” The story of cryptography would be at an end if it weren’t for the practical problem that in order to send a secret message, an equal amount of secret key must first be sent. [Cohen, 1990-1995]
