14 Years?! Happy anniversary, Mandriva Chronicles!

 Yes, today is the 14th anniversary of this humble blog, which I created to register my experiences as a Linux user.

What has changed since last year?

1.  Stability and fewer posts

Well, the Linux distros I use have become so stable that I rarely face a challenge.  This has reduced my post quantity.

Plus, where I work, they have decided to keep people extremely busy, so free time is rare.

2.  Portable Linux machines: always reliable!

In the university where I work, they did a suspicious full 180 turn and switched to Microsoft products.  However, that has not stopped me from using Linux for my work every day: I always use USB drives, which I made portable Linux machines, to stream my virtual lessons and teach in class as well.

As the classroom computers have low specs, MX Linux is my distro of choice.  In my office computer, I generally use Mageia 9.  If fact, I am synchronizing my portable Mageia machines right now following this old post here.

3. The new exam notification system  

This week, they sent an email about a new oral exam notification system.  The funny thing was that they said that it only worked on a Windows computer and urged us NOT TO USE MACs.  Many of my colleagues are Mac users, so I grew curious and decided to test it from my Linux station.  It worked perfectly!

I then replied informing them that the system ran flawlessly from Linux, he,he.

4.  My laptop distros

I upgraded most of the distros and my old ZaReason Strata runs Mageia 9, OpenMandriva Lx 5.0 ROME, Manjaro 23.1, MX Linux, and Elive 3.

I do not use this machine often because the battery is dead and I could never get a replacement.  So, I must keep it plugged to UPS all the time.  

5.  A nephew's migration

My sister in law's son called me once because he installed Linux Mint to a laptop and ran into a problem.  I tried to help him to the best of my abilities and the piece of advice I gave them worked: he could solve his first Linux challenge.

6.  My wife's English course

My wife took an English course and she was very worried because all the software was Microsoft's.  Or so they said.

However, the platform was Moodle and she could work from my Mageia desktop.  Las Monday was her final exam. Everything went fine because Firefox played the audios for the listening exam without a problem.


And that's that.  My productivity has not been affected because of the stability of Linux this year.  So, I am focusing on my health, my daughter's high school matters, and my family in general.

All is good!

Using dd to clone my portable Mageia Linux desktop

Since I returned to the office in 2022 after the remote work mandate was lifted, I have been using portable Linux desktops that I made.

These are convenient USB drives with persistence that I boot and so I can circumvent the restrictions (not to mention the spying) in the Windows desktop.

Anticipating that the USB drive can eventually fail, I have made several copiesÑ I have two MX Linux machines and two Mageia machines.

Even though I synchronize document files using FreeFileSync, I need to make absolutely sure that all the settings of OBS studio are updated, and since I keep changing the configuration for the didactic live streams, the best solution is to clone the USB drive machine I have been using to the backup USB drive machine from time to time.

Doing so is very easy.  First, I plug the source USB and open the Mageia Control Center just to make sure which is the source device (I need this machine in dev/sdb).  After that, I plug the other USB drive, which is the backup.  This is the target USB (the system must identify the target device as /dev/sdc). 

Then I open Konsole in Mageia and type su and my password to be able to type this command:

dd if=/dev/sdb of=/dev/sdc bs=1M status=progress


The status=progress part lets you see how things are going while dd is doing the copy, otherwise the command line gives no feedback and, since the process takes a long time, one might think that nothing is happening.

 


My First 12 Days with Mageia 10: How to enable repos with dnf5

Well, 12 days have passed since I migrated all of my desktop, laptop, and portable work system to Mageia 10. I have not used the work system...
