This is a brief mini-howto on how to build a linux based wireless router out of what amounts to spare parts, using the linux router project's single disk router software. The total cost of each end of the router, including antennas and cabling, is less than 1300 US dollars, which is a considerable cost savings over…
Fiber, a less known concept compared with coroutine, is a pretty powerful addition to cooperative multitasking. As a graphics programmer in game industry, I totally appreciate the great flexibility that fiber brings on the table. As a matter of fact, I feel the tech is a little bit underappreciated due to the lack of…
Service mesh is a blazing hot topic in software engineering right now and rightfully so. I think it’s extremely promising technology and I’d love to see it widely adopted (in cases where it truly makes sense). Yet it remains shrouded in mystery for many people and even those who are familiar with it have trouble…

In the following series of blog posts I will document my attempts to write Linux modules using the Ada language. In part 1, I will demonstrate how to write in Ada and build a simple "hello world" Linux kernel module. Additionally, I will introduce a basic customized Ada runtime to support our "hello world" module…
Wouldn’t you like to live in a world where your monitoring systems only alerted when things were actually broken? And wouldn’t it be great if, in that world, your alerts would always fi…

2022 September 10 What is the best media for long term storage is a question that I read frequently from online forums. First and foremost, as far as I’m aware there is no real “set it and forget it” long term storage. In this digital age, data needs to be validated regularly and cycled to a new media every 5-10 years…
I was lucky enough to attend to EuroBSDCon 2023 and offered the opportunity to talk about one of my favorite OpenBSD stock daemon: relayd(8). The talk was recorded and made available on the EuroBSDCon YouTube channel. . One may check the EuroBSDCon 2023 program for more material. This post attempts a reboot of the…
podman provides an integrated auto-update mechanism, which I recently applied to all of my containers running on feldspaten. The mechanism is nice, but at first appears a bit counter-intuitive. In this post ’m trying to explain how you can use the mechanism and what to watch out for. I’ll start with the trap I think…

Tailscale v1.36 for macOS features a significantly reduced binary size (going from 92MB to 56MB). The effort started out with a chance observation about a surprisingly large executable, and ended up involving some creative approaches using dlopen.

Though most strings online today follow the Unicode standard (e.g., using UTF-8), the Latin 1 standard is still in widespread inside some systems (such as browsers) as JavaScript strings are often stored as either Latin 1, UTF-8 or UTF-16 internally. Latin 1 captures the first 256 characters from the Unicode standard…

Prompt is a terminal that marries the best of GNOME Builder’s seamless container support, the beauty of GNOME Text Editor, and the robustness of VTE. I like to think of it as a companion terminal to Builder. Though it's also useful for immutable/container-oriented desktops like Fedora Silverblue or Project Bluefin…
The new Swift 5.9 release contains a number of helpful, new features for debugging code, including an out-of-process, interactive crash handler to inspect crashes in real time, the ability to trigger the debugger for just-in-time debugging, along with concurrency-aware backtracing to make it easier to understand…
I started working on Flyaway with the intention of becoming familiar with Wayland, its protocols and extensions, and the wlroots library. Instead, I ended up genuinely liking all three.
