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 fourth incarnation of the wonderful Raspberry Pi is upon us. A faster quard-core CPU, up to 4GB of RAM, gigabit ethernet and dual HDMI outputs are the upgrades; there’s USB-C too, but just for power. The CPU boost is a big deal, say early users, but dual-4k displays and 4x the RAM bring it […]
Adam Bradley and Chris Blackburn noticed an unusual, mislabeled eBay listing for a rare beauty: an IBM System/360 in Nuremberg for peanuts. So they set out to do what any self-respecting IBM System/360 fan would do: buy it and fix it up. Thousands of Euros later, they’ve … well, they’ve gotten it out of the […]
This is pioneering computer scientist and US Navy read admiral Grace Hopper (1906-1992) explaining the concept of a nanosecond. From the Computer History Museum: (Hopper) held a B.S. in mathematics and physics from Vassar College (1928) and an M.S. (1930) and Ph.D in mathematics (1934) from Yale University. Hopper began her career teaching at Vassar […]
Looking for a new tablet? If you haven’t upgraded in a while, it might be time to check out the latest iPad Pro for two very good reasons. First, the 2018 model is a real workhorse. The 12X Bionic chip processor means it can handle any task you set out for it, and still have […]
You want wireless earbuds to make an impact on your mood and workout, not the environment. If that’s the case, we’ve got a new contender for AirPod market share: Brio Phantom X7 True Wireless Earbuds. The features on these tiny, comfortable buds are impressive even without the environmental angle. Their Bluetooth 5.0 connectivity is good […]
We don’t ask for much out of our charging cables: Juice up our phone, do it fast and don’t break. It’s supposed to be simple, but keeping your phone plugged in for the night – as most of us do – can actually degrade the life of your battery by overheating it. That’s why one […]
