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.
Ken Shirriff presents Iconic consoles of the IBM System/360 mainframes. This article describes the various S/360 models and how to identify them from the front panels. I’ll start with the Model 30, a popular low-end system, and then go through the remaining models in order. Conveniently IBM assigned model numbers rationally, with the size and […]
For more than two decades, researchers have explored using DNA as a chemical computer. Until now though, DNA computers have only been capable of solving whatever mathematical problem they were built to tackle. Now though, researchers have demonstrated a more general-purpose DNA computer that can run a variety of chemical “programs.” From Caltech: “Think of […]
There aren’t many details in Trump’s “American A.I. Initiative,” but the point appears to be: send a message of technological dominance to China.
With the intuitive software out there today, anyone can become a music producer. You’ve probably heard that from any number of laptop impresarios, but you still have to know how to use the tools – and Logic Pro X is one of the best platforms out there right now. In order to get the most […]
Believe it or not, PDF files have been the go-to format for contracts and forms of any type since 1993. And sure, they’re easily shareable – but that’s about it. When you need to edit or sign a document – and you will – that’s when frustration can set in. Luckily, there are workarounds, and […]
