OpenBSD Kernel Internals — Creation of process from user-space to kernel space.

This time let’s discuss about the process creation in OpenBSD operating system from user-space level to kernel space. We will take an example of the user-space process that will be launched from the Command Line Interface (console), for example, “ls”, and then what happens in kernel-space as a result of it...

oksh.

Unlike other ports of OpenBSD ksh, this port is entirely self-contained and aims to be maximally portable across operating systems and C compilers. We are always looking for new combinations to add support for...

Running Minecraft server on OpenBSD.

For one reason or another, I had to set up a Minecraft server and, given that there is no OpenBSD port, I had to set it up from scratch... BTW, creating an OpenBSD port is out of this post's scope.

OpenBSD has two new C compilers: chibicc and kefir.

In my never ending quest to have oksh support every C compiler in existence, I have ported two more C compilers to OpenBSD. They are chibicc and kefir. As always, let's review them and at the end I'll have links to unofficial ports so that you can play around with these C compilers...

0 Dependency Websites with OpenBSD & AsciiDoc.

I have fallen in love with a recent combination of software to make good looking websites, and having an easy to manage web server. I’m a minimalist in many ways. Really, I find that it makes my life easier. I like to keep my blog up here and don’t want to deal with database updates, language exploits, weird migrations, and so on. I also manage my church’s website. I can’t be having complex solutions that require large amounts of maintenance at multiple times a month because of a dozen pieces of software requiring version upgrades or what have you. Sure, some people have needs for elaborate content management systems, but sometimes you only need a simple site too, and why overcomplicate it?

Analyze OpenBSD’s Kernel with Domain-Specific Knowledge

In this article I want to show how we can analyze the OpenBSD kernel with domain-specific knowledge of spl(9) locking primitives, to find programming errors. This work was sponsored by Genua GmbH. Genua uses OpenBSD as a basis of many of their products. They allow developers to have a retreat twice a year for one week to hack on their own projects. This work is a result of it...

Own Your Calendar & Contacts With OpenBSD, Baïkal, and FOSS Android.

In this tutorial I explain how I use Baïkal running on OpenBSD to host my own calendar and address book, and how to consume them with FOSS apps on Android. Feel free to skip the introduction if you just want to dive straight into the tutorial, it's just there to provide context for those who are new to these topics...

PFRE.

PFRE is a packet filter rule editor for OpenBSD/pf. PFRE is expected to be used by beginners and system administrators alike. The UTMFW and PFFW projects use PFRE on their web administration interfaces. If you don't want to install PFRE yourself, you can download the installation files of UTMFW or PFFW to test drive PFRE easily...

Programming Style Influences.

The point of this post isn't try and persuade you that you should also use OpenBSD's style as an influence, but I wanted to show what the effects of a programming style influence can be. I could equally have talked about how BBC BASIC, Arm 2 assembly, Python, Template Haskell, or many other languages and systems have influenced me, and I think the overall thrust of this post would have been similar...

Let's try V on OpenBSD.

A long time ago, I submitted a patch for V. And then I mostly forgot about V. GitHub recently reminded me of its existence. Let's see if V still works on OpenBSD. I am going to build it, see if it is easily able to be made into a port, and then try some of their upstream-developed programs...
