In 2014, a graduate student at the University of Waterloo, Canada, named The suspicion, harbored by many physicists and mathematicians over the decades but rarely actively pursued, is that the peculiar panoply of forces and particles that comprise reality spring logically from the properties of eight-dimensional numbers called “octonions.” As numbers go, the familiar real numbers — those found on the number line, like 1, π and -83.777 — just get things started. Real numbers can be paired up in a particular way to form “complex numbers,” first studied in 16th-century Italy, that behave like coordinates on a 2-D plane. Adding, subtracting, multiplying and dividing is like translating and rotating positions around the plane. Complex numbers, suitably paired, form 4-D “quaternions,” discovered in 1843 by the Irish mathematician William Rowan Hamilton, who on the spot ecstatically chiseled the formula into Dublin’s Broome Bridge. John Graves, a lawyer friend of Hamilton’s, subsequently showed that pairs of quaternions make octonions: numbers that define coordinates in an abstract 8-D space. There the game stops. Proof surfaced in 1898 that the reals, complex numbers, quaternions and octonions are the only kinds of numbers that can be added, subtracted, multiplied and divided. The first three of these “division algebras” would soon lay the mathematical foundation for 20th-century physics, with real numbers appearing ubiquitously, complex numbers providing the math of quantum mec...

Chris Pinkham was walking through a data center that would one day house Amazon's This was a decade ago, when Pinkham oversaw the hardware and software that ran Amazon, and the company was considering a spot in the data center, which housed machines for many web operations and other businesses. Google would later Pinkham was struck by how different the machines looked – and how hot they were. Even then, Google was running its website on "They were clearly not your average Dell, HP, IBM servers. They were white box machines, very densely packed. They weren't in containers. They were just blades jammed into these custom racks," remembers Pinkham, who went on to lead the team that built the Elastic Compute Cloud and now runs a cloud software startup called It was a moment that would push Pinkham and Amazon in a new direction. Inspired by Google, Pinkham says, the company began to rethink the way it used servers, moving away from the big, beefy, expensive machines, toward cheaper gear that would let the company expand its operation far more quickly. "Google was a very impressive company to us – and a bit of a role model for how to run infrastructure at scale," he says. "I and others spent a lot of time pondering on what those servers meant." And now, according to James Hamilton, the man who oversees Amazon's current data centers, the company is building its own servers in tandem with Asian manufacturers Once you reach a certain size, says Hamilton, it only makes sense to build...

Here are the 20 biggest ransomware attacks of 2021 in chronological order. 1. Buffalo Public Schools While many schools were hit by ransomware in 2021, the Buffalo Public School system in New York, which serves 34,000 students, was one of the biggest. The attack on March 12 shut down the entire school system, canceling both remote and in-person instruction for a few days. Former Buffalo Schools superintendent Kriner Cash issued a 2. Acer An attack on Taiwan-based PC manufacturer Acer resulted in the highest ransom demand to date: $50 million. On March 18, we Download 1 Download this entire guide for FREE now! Acer provided a statement to TechTarget: "Companies like us are constantly under attack, and we have reported recent abnormal situations observed to the relevant law enforcement and data protection authorities in multiple countries." It's unclear if the PC manufacturer paid the ransom. 3. CNA Financial One of the biggest insurance carriers in the U.S. was hit by a ransomware attack on March 21, causing a network disruption. In a statement posted to its website, CNA referred to it as a "sophisticated cyber attack" and said that out of an abundance of caution, it took "immediate action by proactively disconnecting [its] systems" from the CNA network. Restoration was not fully complete until CNA said the investigation "identified the scope of impacted data in the incident as well as the servers on which the data resided." The insurance carrier said it did not believe cla...
