Collaborate Disseminate
An intriguing paper published by researchers at the University of Michigan describes a new processor architecture capable of self-encryption that can fend off any hacks. A DARPA-supported project, the new chip design renders the current electronic secu… Continue reading Scientists claim to have invented the unhackable processor
Arduinos are a handy tool to have around. They’re versatile, cheap, easy to program, and have a ton of software libraries to build on. They’ve only been around for about a decade and a half though, so if you were living in 1989 and wanted to program a microcontroller you’d probably be stuck with an 8-bit microprocessor with no built-in peripherals to help, reading from a physical book about registers and timing, and probably trying to get a broken ribbon cable to behave so it would actually power up. If you want a less frustrating alternate history to live in, …read more

Security researchers have identified a cyberespionage group that has been stealing data from policy and diplomatic organizations in South America and South Asia since at least 2015. “While cyberespionage attacks are often seen against targets in the U.S., Europe, and Asia, it is much less common to see South American countries targeted,” researchers from Symantec..

Modern microprocessors are a marvel of technological progress and engineering. At less than a dollar per unit, even the cheapest microprocessors on the market are orders of magnitude more powerful than their ancestors. The first commercially available single-chip processor, the Intel 4004, cost roughly $25 (in today’s dollars) when it was introduced in 1971.
The 4-bit 4004 clocked in at 740 kHz — paltry by today’s standards, but quite impressive at the time. However, what was remarkable about the 4004 was the way it shifted computer design architecture practically overnight. Previously, multiple chips were used for processing and were selected …read more

Although AMD has been losing market share to Intel over the past decade, they’ve recently started to pick up steam again in the great battle for desktop processor superiority. A large part of this surge comes in the high-end, multi-core processor arena, where it seems like AMD’s threadripper is clearly superior to Intel’s competition. Thanks to overclocking expert [der8auer] we can finally see what’s going on inside of this huge chunk of silicon.
The elephant in the room is the number of dies on this chip. It has a massive footprint to accommodate all four dies, each with …read more
