Sandsifter throws random machine code instructions at microprocessors, just to see what happens.
The sandsifter audits x86 processors for hidden instructions and hardware bugs, by systematically generating machine code to search through a processor's instruction set, and monitoring execution for anomalies. Sandsifter has uncovered secret processor instructions from every major vendor; ubiquitous software bugs in disassemblers, assemblers, and emulators; flaws in enterprise hypervisors; and both benign and security-critical hardware bugs in x86 chips.
With the multitude of x86 processors in existence, the goal of the tool is to enable users to check their own systems for hidden instructions and bugs.
I demand to see this scene in technothrillers pronto.
The Universal Serial Bus specification was introduced by a consortium of large tech companies in 1996 to standardize the way peripherals connect to computers. In this episode of Nostalgia Nerd on YouTube, you can learn about the history of USB, and why the connector configurations change so frequently. This 20-minute video was more interesting than […]
The miniature model supercomputers that Cray salespeople carried sometimes hit eBay, and they’re getting quite pricey. This 3.75″ tall scale model of the Cray X-MP, once the world’s fastest computer, is on offer for $700. I wonder, if you put a Rasberry Pi in it, would the resulting machine be faster than a Cray X-MP? […]
With all due respect to our vegetarian friends, there might be nothing more intrinsically linked to the 4th of July holiday than a big ole cookout. Sure, fireworks and celebrating the birth of a constitutional republic are great too, but showing off your cooking prowess with a brilliantly seared, mouth-watering slab of grade-A American beef […]
We’re at the midway point of 2020. So…how’s the year going for you so far? Yeah…we can guess. But while there’s a lot about 2020 we can’t directly control, maybe a little retail therapy can help make you feel better. Sure, the 39 items we gathered together can absolutely bring a smile to your face. […]
When revved-up kids used to dribble a basketball through the kitchen or practice their footwork with a soccer ball in front of the television, exasperated parents would often just send ‘em outside to play. But these days, sending kids out might not be the best course of action. Despite all the changes, many budding young […]
