UNIX Syscalls
LinuxLinux syscalls are defined in include/linux/syscalls.h. Syscalls use the same parameter order across platforms, but some (e.g. sys_stat64) are only defined on some platforms, and others (e.g. sys_clone) have different parameters depending on kernel compilation options. Syscall numbers are platform-dependent. Manpage syscalls(2) lists syscalls and which kernel version they were added in. Manpa
Metal Tutorial: Getting Started
In iOS 8, Apple released its own API for GPU-accelerated 3D graphics: Metal. Metal is similar to OpenGL ES in that it’s a low-level API for interacting with 3D graphics hardware. The difference is that Metal is not cross-platform. Instead, it’s designed to be extremely efficient with Apple hardware, offering improved speed and low overhead compared to using OpenGL ES. In this tutorial, you’ll get
Mipmapping and the Blit Command Encoder
In this article we will learn about mipmapping, an important technique for rendering textured objects at a distance. We will find out why mipmapping is important, how it complements regular texture filtering, and how to use the blit command encoder to generate mipmaps efficiently on the GPU. The sample app illustrates the effect of various mipmapping filters. The mipmap used here is artificially c

Rendering a Triangle with Apple's Metal API, using Go Did you learn that macOS 10.14 and newer has marked its OpenGL API support as deprecated? Are you interested in giving Apple's Metal API a try? Are you a fan of Go and don't feel like switching to Swift or Objective-C for this? Then this post is for you. By the end of this post, we'll render a single frame with a colorful triangle using Metal.
Binding Threads to Cores on OSX
When I was porting the mbw to the OSX, I found that sched_getaffinity pthread_setaffinity_np are missing, so that I could not bind a thread to a core. The result is the mbw threads could be running on the same core and compete for per-core resources, although the OSX kernel scheduler is unlikly to do so. I simply simulate these calls by using native OSX calls. The first thing to do is to detect th

Cross-compile and link a static binary on macOS for Linux with cargo and rust
Cross-compile and link a static binary on macOS for Linux with cargo and rust One Go feature which I’m using regularly is cross-compiling Go code to other platforms (usually from macOS to linux-amd64). In Go, this is a built-in feature that “just worksâ€. The following command produces a statically linked ELF binary which can simply be copied and run on a Linux machine: $ GOARCH=amd64 GOOS=linux go

5 Unix Commands I Wish I'd Discovered Years Earlier
I’ve been using *nix systems for quite a while. But there are a few commands that I somehow overlooked and I wish I’d discovered years earlier. 1. man ascii This prints out the ascii tables in octal, hexadeciamal and decimal. I can’t believe I didn’t know about this one until a month ago. I’d always resorted to googling for the tables. This is much more convenient. ASCII(7) BSD Miscellaneous Infor

MacAVR - AVR development under MacOS X
The following instructions are from early 2007 and are pretty outdated by now. They are still here for reference, but they are not maintained anymore and very likely won't work with recent versions of MacOS anymore. After having developed software for the AVR under Windows and Linux the only major plattform missing was MacOS X. Since we recently got a Mini Mac in our home office i decided to build
