Packaging software is notoriously tricky. Every language, framework, and build system has its quirks, and the variety of artifact types — from Debian packages to OCI images and cloud images — only adds to the complexity. This blog is a deep-dive on Canonical’s “craft” tools, how they evolved, and how to use them to simplify package maintenance.| Jon Seager

Around a decade ago, I was happy to learn about bcache – a Linux block cache system that implements tiered storage (like a pool of hard disks with SSDs for cache) on Linux. At that stage, ZFS on Linux was nowhere close to where it is today, so any progress on gaining more ZFS features in general Linux systems was very welcome. These days we care a bit less about tiered storage, since any cost benefit in using anything else than nvme tends to quickly evaporate compared to time you eventually...| Jonathan Carter

These days, in the covid world we live in we have multiple videoconferences every day, with colleagues, family, friends… The average number of people attending has grown, and when I was in a call some time ago, I wondered, what would be the “optimal” way of splitting the videconference application window among the people in … Continue reading "How to share your video-conference window among attendees – or, the many ways of splitting a rectangle in many"| Alfonso Sánchez-Beato's blog
Ubuntu Core is especially designed for appliances: you can very easily create a customized image by defining your own model assertion and including the specific snaps you need for your target application. At the same time, the system is security-first and you can finish configuration on it only by connecting via a system console. However, … Continue reading "Configuring connectivity for your Ubuntu Core appliance"| Alfonso Sánchez-Beato's blog
Ubuntu Core (UC) is Canonical’s take in the IoT space. There are pre-built images for officially supported devices, like Raspberry Pi or Intel NUCs, but if we have something else and there is no community port, we need to create the UC image ourselves. High level instructions on how to do this are found in … Continue reading "Porting Ubuntu Core 18 to nvidia Jetson TX1 Developer Kit"| Alfonso Sánchez-Beato's blog
In chapter 5 of his mind-blowing “The Road to Reality”, Penrose devotes a section to complex powers, that is, to the solutions to $$w^z~~~\text{with}~~~w,z \in \mathbb{C}$$ In this post I develop a bit more what he exposes and explore what the solutions look like with the help of some simple Python scripts. The scripts can … Continue reading "Analysis and Plots of Solutions to Complex Powers"| Alfonso Sánchez-Beato's blog
In the conclusions to my last post, “Modifying System Call Arguments With ptrace”, I mentioned that one of the main drawbacks of the explained approach for modifying system call arguments was that there is a process switch for each system call performed by the tracee. I also suggested a possible approach to overcome that issue … Continue reading "Filter and Modify System Calls with seccomp and ptrace"| Alfonso Sánchez-Beato's blog
Occasionally I find myself processing input data which arrives as a stream, like data from files or from a socket, but that has a known structure that can be modeled with C types. For instance, let’s say we are receiving from a socket a parcel that consists on a header of one byte, and a payload that is an integer. A naive way to handle this is the following (simplified for readability) code snippet:| Alfonso Sánchez-Beato's blog
