I have a lovely, and reasonably priced, Mini Panda Rice Cooker. It does not have any SmartHome features. You put in water and rice, press a button, it cooks rice. Nice! The only problem is - I don't know how long the rice will take to cook. It uses "Fuzzy Logic" to work out exactly how much heat and time is needed for…

The Apple Jonathan: A 1980s concept computer that never shipped
In the middle of the 1980s, Apple found itself with several options regarding the future of its computing platforms. The Apple II was the company’s bread and butter. The Apple III was pitched as an evolution of that platform, but was clearly doomed due to hardware and software issues. The Lisa was expensive and not…

ZenHammer: Rowhammer attacks on AMD Zen-based platforms
Our work shows that it is possible to trigger Rowhammer bit flips on DDR4 devices on AMD Zen 2 and Zen 3 systems despite deployed TRR mitigations. This result proves that AMD systems are equally vulnerable to Rowhammer as Intel systems , which greatly increases the attack surface, considering today’s AMD market share…

ARM64EC (and ARM64X) Explained
ARM64EC (and ARM64X) Explained Probably the most confused looks I get from other developers when I discuss Windows and ARM64 is when I used the term " ARM64EC ". They ask is the same thing as ARM64? Is it a different instruction set than ARM64? How can you tell if an application is or ARM64 ARM64EC?

Creating an autopilot in X-Plane using Python
Introduction Today’s post will take us in a slightly different direction than the last few. Today’s post will be about hooking up some Python code to the X-Plane flight simulator to enable development of an autopilot using PID (proportional-integral-derivative) controllers. I’ve been a fan of flight simulators for…
