unusual C programming idiom that manually implements loop unrolling using interleaved control structures

Back in spring 2020, I was wrapping up the distributed systems course I was teaching, and for the last lecture, decided to spend a little time poking at the question of who actually invented vector clocks. Most people who need something to cite for vector…

io_uring is an async interface to the Linux kernel that can potentially benefit networking. It has been a big win for file I/O (input/output), but might offer only modest gains for network I/O, which

In this blog post I’ll show you a couple of interesting examples with lambda expressions. Do you know how to write a recursive lambda? Store them in a container? Or invoke at compile time?
See in the article.

An unfortunate side effect of the rising popularity of Apple’s ARM-based computers is an increase in unportable assembly code which targets the 64-bit ARM ISA. This is because developers are writing these bits of assembly code to speed up their programs when…

Thanks to the C language standard, it's trickier than it seems.

Exploring the world of Zig and Deep Neural Networks

In my previous article on polymorphic allocators, we discussed some basic ideas. For example, you’ve seen a pmr::vector that holds pmr::string using a monotonic resource. How about using a custom type in such a container? How to enable it? Let’s see.
The…
