Processor problems have been in the news lately, due to the Meltdown and Spectre vulnerabilities. But generally, engineers writing software assume that computer hardware operates in a reliable, well-understood fashion, and that any problems lie on the software side of the software-hardware divide.
We explain how C array sizes become part of the binary interface of a library and examine ways to avoid ABI compatibility issues.
Since Version 10.10 (Yosemite), OS X contains Hypervisor.framework, which provides a thin user mode abstraction of the Intel VT features. It enables apps to use virtualization without the need of a kernel extension (KEXT) – which makes them compatible with the OS X App Store guidelines.
Barring divine intervention, Windows 10 Enterprise LTSC 2019 ( formerly LTSB ) may be the least bad option:
The year is 1983, and several Apple employees visit Brown University, and get some idea of what Universities want in a computer for the coming future. The big buzz of the era was the so called 3M machine:
In response to a question on Twitter 1 , Richard Hipp wrote about why SQLite uses a bytecode VM for executing SQL statements.
