COVID-19, Telework, and Linux! Happy Anniversary, Mandriva Chronicles!

With the present sanitary emergency created by COVID-19, I've been away from this blog for two months already.

It's not that I have not had the motivation to post, no.  Actually, my work load blew up to three times its normal size because of the mandatory teleworking policies of the university where I work.

In the course of three weeks, I saw everyone move to cyberspace (willingly or reluctantly).  Anxiety, contradictory policies, and uncertainty became the new educational environment for many.  And, with this, I forgot that last Friday was the 10th Anniversary of this humble blog.

 What can I report?

1.  Well, the idea of the younger generations being "digital natives" shattered into a million pieces; as I had always suspected, it was nothing but a myth.  This crisis forced students to use the Web to study and, in great numbers, they are admitting defeat.  It turns out that their online skills seem nothing else that proficiency for using social networks: they cannot read and concentrate, have problems understanding how to post in forums, and become confused when submitting their assignments in an online mailbox.

2.  Linux has been up to the challenge: even though I have been forced to install programs such as Zoom and (yuck!) MS Teams on my laptop and my daughter's desktop, PCLinux OS and Mageia have been reliable, helping me attend meetings and helping my daughter continue with her elementary school classes.

Megatotoro and I decided to ditch Zoom and favored a more flexible online approach.  This idea implied producing lots of audiovisual material --something that we have no training on.  Thus, we had to learn how to produce videos in Linux for our courses.  In a week, I taught myself Kdenlive and Openshot, became more proficient with Audacity, and relied more in the image-editing of the always trustable GIMP.

In the meantime, other professors have been struggling trying to adapt their lessons to something they can deliver through Zoom meetings.  How successful that attempt is I cannot say.  Students claim that Zoom sessions generate anxiety and make them very tired, which has been confirmed in this article.  

So, yes, it has been a busy time.  But, all, in all...

Linux truly saved me from this technological virus that seems to be eroding the mental health of my colleagues...

HAPPY BELATED ANNIVERSARY, MANDRIVA CHRONICLES!!

Happy 20th Anniversary, The GIMP!

On November 21, 1995, the announcement that there was a program for image manipulation was made.

This program, originally named The General Image Manipulation Program and now known as the GNU Image Manipulation Program (The GIMP), in my opinion, is the best software I have ever used to work with images.

I am not a professional image designer.  However, as a teacher, one frequently needs to modify or enhance a particular image for a presentation.

Adobe Photoshop is heavy and too expensive.  I used to resort to an assortment of programs that included Irnfanview and Satori, which I could use for free and that satisfied my humble needs.

Then I migrated to Linux and discovered The GIMP.

With it, one can resize images, modify colors, change backgrounds, enhance pictures, create effects, you name it... It is, truly, an amazing program.  In general, every time I have to work with images, I look for this reliable software.  Perhaps batch conversion is the only operation that I prefer to do with other software (Gwenview).

And I've noticed that The GIMP has two points of controversy:  first, many people object to the acronym because of the offensive connotation of the resulting word.  Second, there seems to be an ongoing debate between the Gnome and KDE communities concerning "the way of the desktop" and The GIMP is in the middle.  Gnome strives for simplification while KDE presents lots of options...and The GIMP does not seem to follow Gnome's motto.  

But let's not spoil the party.   The GIMP is here and that's the reason for the celebration!

HAPPY 20TH ANNIVERSARY, THE GIMP!!!

Gimp in Mandriva, a glitch than can help you rescue files

As I have said before, Mandriva is a nice Linux distribution for working if you blow up your Windows system. However, unless you install it, Mandriva ONE cannot be used as a rescue distro because it does not mount other partitions in Live mode, so you cannot access and retrieve your stored data. That was at least what I thought until yesterday.

I was testing Mandriva ONE 2010.2 and, sure enough, my other partitions could not be accessed in Dolphin (it reported the same error message when trying to mount them). I believe this is done to prevent damage to the primary OS in the computer, be it Linux or Windows.

The interesting part is that I decided to launch Gimp, the GNU image manipulation software, to see how fast it would open. It opened pretty fast, so I went to the menu to look for any image to load it... and, as I was doing it, I was saying to myself that the attempt was a futile one since I had no images in Live mode. Nevertheless, I saw my other partitions in the open menu and playfully hit the icon where my home partition is sitting on my hard disk. I got a pop up message informing that the operation I wanted to perform required root privileges and asked for my root password.

A root password!
A bit amused and expecting an error message, I typed "root" and voilà ! It mounted my home partition. In disbelief, I looked for a picture there and opened it, quickly modified it, and saved it to my home partition in a different folder.

I tried to open the folder in my home partition with Dolphin and it worked: I found the new image file.

I repeated the process with Gimp to see if it would mount my Windows partition as well. It did, so I took an image from Windows, modified it, and put it into a different folder. Using Dolphin once again, I noticed that my Windows partition was also mounted. I looked for the new folder I had created and located the file there.

I thought that it might be a glitch in Mandriva 2010.2, so I repeated the process using a Mandriva ONE Spring (2010.1) CD. When Gimp asked me for my root password, instead of typing "root", I hit "cancel" and it went ahead and mounted my home partition anyway. The same happened with my Windows partition, which shows that inputting a password is not actually necessary. Other programs, such as Gwenview, could also open files in other partitions after the process.

Now, the practical application of this is that you can retrieve all sorts of files (not just images) once your other partitions are mounted. In other words, you can use Mandriva as a rescue distro provided that you have any usb flash drive in which you can copy your retrieved files.

It is just too bad that Mandriva ONE does not come with K3b, the CD/DVD burning software. It could have made Mandriva a very good candidate for my perfect rescue distro quest.
