Just like last week, let’s add some more information to our tmux status bar: this time, the current battery level.

People have asked me how to display the weather on the status bar of my tmux session, as shown in a previous post of this blog.

Hisham recently said something very true: Remember when we all silently told ourselves “stop trying to make QR Codes happen, it will never catch on”?

Last week I enumerated some strategies to split and join large files on the terminal; let’s see how to do more split and join, but this time for any text on the standard input, just like the creators of Unix wanted us to operate on data.

This post explains some useful combinations of commands that you can use on Linux (or sometimes also in other operating systems) to split large files into smaller pieces, and then how to rebuild the original file from those pieces.

I’ve recently discovered WezTerm, also known as “Wez’s Terminal Emulator” by Wez Furlong, and I’ve adopted it completely, becoming my default terminal application.

Five years ago I bought a TUXEDO Computers laptop and finished my migration to Linux completely, without ever looking back.

During the preparation of my “Learning OpenShift” course for LinkedIn Learning, I used OpenShift Local (formerly known as “CodeReady Containers” or CRC) to demonstrate the various features of the platform from a developer’s point of view.

In the past few months I’ve been writing about my software archeology experiments, including how to convert old HTML code from 1999 to run in today’s browsers, how to run Macromedia Flash movies with Ruffle, or even how to run Java applets now that they aren’t supported anymore.

As I’ve said in the past, producing videos in Linux isn’t very straightforward or stable; it can be a bit of bumpy ride. But I’m stubborn, and Linux is the platform I want to use, so when I was tasked with the creation of “Getting Started” video guides for our products at VSHN, I used Linux to create them.

One of the greatest discoveries I’ve made after switching to the Linux galaxy is, without any doubt, the fantastic Restic; a backup tool that deserves to be better known and more widely used.

In December 4th, 2005, I published my first blog post about Linux. I wrote it on Ubuntu 5.10 “Breezy” after installing it on my faithful iBook G3. Many years have passed, and I’ve become a full-time Linux user now, having used no other operating system in the past 5 years.

The other day, I had friends in Bolivia asking me if they could install Windows on a laptop they got through an NGO that initially came bundled with Linux.

Last week I talked about Firefox extensions, last year I talked about VSCode extensions, now it’s time to talk about GNOME extensions.

In my quest to learn more and more programming languages, I recently dipped my toes into the D Programming Language. My reaction to it involves sadness; on the positive side of things, the language is undeniably brilliant.

I use Flatpak a lot, on my work and personal laptops. I had to find a few tips and tricks to make it work the way I wanted, using all the apps I prefer.

For the past 20 years there’s been this trend to give names to a particular set of operating system, programming language, database tech, and something else.

If you are developing apps for GNOME, I kindly ask you to pay attention to the following three key points of application usability.

There are quite a few package managers available in Linux, and it’s hard to figure out which one to use for what.

For those interested in buying a computer with Linux built-in, here’s a list of options.

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

Let’s talk about the worst part of my Linux experience so far: video editing.

My exploration of Rust continues; this week, I rewrote a Python Flask application I use for demos at work.

This is the story of how, after being a loyal macOS user for 15 years, I decided to start using Linux full-time.

This is the presentation I gave at the second App Builders Conference in Lausanne, Switzerland, April 25th, 2017.

Modern operating systems provide a clear separation of the kernel processes from those running in user space, which prompts the question of how to access I/O devices from user processes, without breaking the above mentioned architectural separation, which guarantees stability, security and performance.

Jedi Knights, when they achieve a certain level of maturity in their craft, are told to build their own lightsaber, as one of the final steps of their training.

And it’s called UTUTO: UTUTO es una distribución de GNU/Linux, denominada en referencia a una lagartilla o Geco así­ conocido en el norte de Argentina

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.

After upgrading my good ol’ PC to Dapper, I proceeded to download and burn a copy of it for PowerPC systems, and I have managed to install it in my old faithful G3 iBook in dual boot, with Mac OS X 10.

“Dapper”, the new version of Ubuntu has been released yesterday! So I downloaded the ISO file, burn the CD down and proceeded to install it over my old Breezy Kubuntu installation.

Well, that was a long title. My mother recently changed her 4-year old Dell Inspiron 4100 for a brand new iMac G5, so I took that old laptop (20 GB hard disk, 256 MB RAM) and, after backing up her data, wiped it completely and reinstalled it with the following configuration:

OK, so this time I’ve tried to make the same I’ve described before, but for Kubuntu 5.

If you enjoy Microsoft PR material, you may find this “Get the facts” page somewhat interesting.

This is my first post from a brand new world.
