There have been several attempts to revive my syprog.blogspot.com blog on system programming. Now, I believe, it's either do it or leave it. I decided to migrate the blog to a new location - my personal website, as the first step, and start spilling the knowledge I've collected over the past decade.

I have recently seen tones of posts about writing kernel module for a pre-compiled kernel on the Internet. Guys are doing good work, but there is one thing that I personally did not like - they all refer you to the configuration file for such kernel, which may be obtained this way or the other. Well, having configuration of the running kernel makes it almost no different from building a module for a kernel you compiled yourself (just almost). The bottom line - you want something to be done your way, do it yourself.

Virtual machines and Software Frameworks are an initial part of our digital life. There are complex VM and simple Software Frameworks. I did my best to describe the way VM code may interact with native code and the Operating System, however, the backwards interaction is still left unexplained. This article is going to fix this omission.

Threads are everywhere. Even now, when you browse this page, threads are involved in the process. Most likely, you have more than one tab opened in the browser and each one has at least one thread associated with it. The server supplying this page runs several threads in order to serve multiple connections simultaneously. There may be unnumbered examples for threads, but let us concentrate on one specific implementation thereof. Namely, Linux implementation of threads.

I was recently digging through my sources and came across a small ANN (artificial neural network) library I wrote several months ago in 64 bit Intel Assembly language (FASM syntax) and decided to share it with my respected readers hoping that it may be useful in some cases.
