A decade ago, when containers where the hot new thing in town, learning about them required lots of command typing on the terminal. These days, thanks to tools like Podman Desktop, the task is oh so much simpler than ever. In this article we’re going to learn some common container technology concepts, using the visual user interface of Podman Desktop to help us during the process.

Continuing with my exploration of old versions of Word in various platforms, I wanted to experience one of the last versions of Microsoft Word for DOS, Word 5.5. Here are the instructions to run it on any platform that supports DOSBox Staging.

I’ve been using some famous versions of Microsoft apps lately, of the “pre-Office” era: Word 5.1a and Excel 4, which were both running on the Macs available to students at the high school I attended in Geneva around 1993. This article provides the instructions for you to do the same with Basilisk II.

Mini vMac is a very common “Classic Mac OS” emulator, and this article contains the instructions required to get it running on Fedora 41.

30 years ago I bought a copy of the recently released IBM OS/2 Warp 3 operating system, and I used it in the primary partition of my computer for a while, until around 1997, when I sold my 486 PC and moved back to Argentina.

Last Monday I released the 59th issue of De Programmatica Ipsum, my dear monthly magazine about code, developers, and society, and this month I talked about BASIC in all of its flavors. As part of the preparation of this issue, I dived into the world of Minimal BASIC code, the one with source code line numbers, the one that would start immediately after powering up your computer, and the one that brings endless nostalgia.

So Amazon Prime Video (of all people!) published a blog post about how they’re returning to monoliths, relayed by DHH, generating lots of noise, to the point that even Dr. Werner Vogels himself, CTO at Amazon, had to pour some thoughts about the subject.

Back in the 1990s, shared libraries were all the rage. Instead of having to ship a 20 MB *.exe file to your customer in various floppy disks, you could cut some code out, put it in a set of *.dll files, and reuse that code across all your products. Every vendor would then install lots of DLL files in your system, and they would be reused by other apps from the same vendor.

This was my speech for the WeAreDevelopers Container Day on February 3rd, 2021. The talk will feature a live demo showing how to build, optimize, and distribute containers to be reused in as many environments as possible, 100% based on the experience of the VSHN team.

If you work in the tech field, the word “Kubernetes” is all over the place these days; for those new to the subject, it can be very confusing to understand what it is, what it does, and why it is so important to so many people.

Last weekend I decided to learn Vagrant to build a simple k3s Kubernetes cluster on top of a set of VirtualBox virtual machines.

I’ve been playing with Alpine Linux on VirtualBox, and here are some notes I took during the process.

What’s the hot word these days? Virtualization. Even December 2006’s issue of Dr.

Since I discovered Ubuntu I’ve been trying to install it in different hardware, in different computers, even in virtual machines, and I just love it.

Since data and instructions are stored in RAM in pretty much the same way, a priori the CPU cannot distinguish each other, but by the cycle in which the binary chunk is fetched from memory.
