Happy Belated 15th Anniversary!

Wow!  Another year flew by! 

Yes, I have not been very active posting on this blog for some time now. In fact, the last post was precisely on the 14th anniversary of this humble space.

These are the major changes since last year:

1.  My ZaReason Strata laptop is dying

The system I purchased from the now gone ZaReason company in 2014 is finally on its last breath. The battery malfunctioned six years ago and there is no replacement, so I had to keep it connected to a backup battery to be able to use the machine.  However, because its speakers started producing strange noises, I have not used this machine since 2022. 

When I tried to use it last month, it would not start at all. I thought it was finally out, but then changed the power brick and the laptop booted normally. Manjararo, OpenMandriva Lx, Mageia, Elive, and MX Linux are still there, fully operational.

However, the lid is showing signs of wear and the cables of the screen are now showing in between the broken hinges.

Well, it is, after all, an 11-year old laptop. 

I remember how, during the pandemic of 2020, the ZaReason people issued a statement concerning their closing of operations. Those were troubled times and, the message, with an apology to clients, made me very sad.

Yet, your product is still here... Battered after a long time, but working.

No, ZaReason people. You did not disappoint me. 


2.  UEFI mayhem and portable Linux machines

Last year, I wrote:

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.

Well, turns out that, at the beginning of this year, the university decided to replace all HDDs for SSDs. This created a problem for me since all my portable Linux machines booted using legacy mode.

I had to reinstall all systems into the USB drives from the physical computer at the university office to make sure that no UEFI or secure boot setting prevented me from booting the devices.

It was a somewhat slow process, but everything worked. So, I am still doing all of my job from those portable machines.

3. The new laptops 

I had to find a Windows 11 laptop for my daughter since she needs Windows and office for a high school class.  I decided to get second-hand laptops and, thus, I bought an HP slimbook for her and an HP ZBook for me.

I dual-booted hers with Mageia 9 and wiped Windows from mine entirely to also boot Mageia 9. The two laptops work great, but I miss the wired internet connection.  I am posting this from the ZBook with Mageia.

----------------------------------------

So, this is what has been going on.

I wish I could have more time to post, but family and work responsibilities keep me busier and busier every year.




 

My Linux journey has not ended!

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...
