Emulating x86 on Apple’s AARCH64 x64 Emulator
You might know [Evan Martin] as the developer of retrowin32. It’s a Windows and x86 emulator designed to run on a Mac or on the web. He’s recently been exploring …read more Continue reading Emulating x86 on Apple’s AARCH64 x64 Emulator
Learning x86_64 Assembly By Building A GUI From Scratch
Some professional coders are absolutely adamant that learning to program in assembly language in these modern times is simply a waste of time, and this post is not for them. …read more Continue reading Learning x86_64 Assembly By Building A GUI From Scratch
Intel Suggests Dropping Everything But 64-Bit From X86 With Its X86-S Proposal
In a move that has a significant part of the internet flashing back to the innocent days of 2001 when Intel launched its Itanium architecture as a replacement for the …read more Continue reading Intel Suggests Dropping Everything But 64-Bit From X86 With Its X86-S Proposal
AVX-512: When The Bits Really Count
For the majority of workloads, fiddling with assembly instructions isn’t worth it. The added complexity and code obfuscation generally outweigh the relatively modest gains. Mainly because compilers have become quite …read more Continue reading AVX-512: When The Bits Really Count
Assembly Language for Real
We all probably know that for ultimate control and maximum performance, you need assembly language. No matter how good your compiler is, you’ll almost always be able to do better by using your human smarts to map your problem onto a computer’s architecture. Programming in assembly for PCs though is …read more
Odyssey Is A x86 Computer Packing An Arduino Along For The Trip
We love the simplicity of Arduino for focused tasks, we love how Raspberry Pi GPIO pins open a doorway to a wide world of peripherals, and we love the software ecosystem of Intel’s x86 instruction set. It’s great that some products manage to combine all of them together into a …read more

Creating Black Holes: Division By Zero In Practice
Dividing by zero — the fundamental no-can-do of arithmetic. It is somewhat surrounded by mystery, and is a constant source for internet humor, whether it involves exploding microcontrollers, the collapse of the universe, or crashing your own world by having Siri tell you that you have no friends.
It’s also one of the few things gcc will warn you about by default, which caused a rather vivid discussion with interesting insights when I recently wrote about compiler warnings. And if you’re running a modern operating system, it might even send you a signal that something’s gone wrong and let you …read more

Learn ARM Assembly with the Raspberry Pi
We live in a time when you don’t have to know assembly language to successfully work with embedded computers. The typical processor these days has resources that would shame early PCs and some of the larger ones are getting close to what was a powerful desktop machine only a few years ago. Even so, there are some cases where you really want to use assembly language. Maybe you need more speed. Or maybe you need very precise control over timing. Maybe you just like the challenge. [Robert G. Plantz] from Sonoma State University has an excellent book online titled “Introduction …read more
GoScanSSH Malware Targets SSH Servers, But Avoids Military and .GOV Systems
