Rust Web Development
This article is part of a chapter of Rust Web Development which didn't make the cut to be in the book.

There are many steps involved for two parties to be able to communicate with each other. Application developers are mainly confronted w

My First Contribution to Linux
I've been spending more of my spare time in recent years studying the Linux source tree to try to build a deeper understanding of how computers work.

OpenBSD is an operating system that's famous for its focus on security. Unfortunately, OpenBSD leader Theo states that there are only 7000 users of OpenBSD.

How a simple Linux kernel memory corruption bug can lead to complete system compromise
In this case, reallocating the object as one of those three types didn't seem to me like a nice way forward (although it should be possible to exploit this somehow with some effort, e.g. by using count.counter to corrupt the buf field of seq_file). Also, some systems might be using the slab_nomerge kernel command line flag, which disables this merging behavior. Another approach that I didn't look

Accelerate Python code 100x by import taichi as ti | Taichi Docs
Python has become the most popular language in many rapidly evolving sectors, such as deep learning and data sciences. Yet its easy readability comes at the cost of performance. Of course, we all complain about program performance from time to time, and Python should certainly not take all the blame. Still, it's fair to say that Python's nature as an interpreted language does not help, especially
