The LibreOffice Migration Finally Reached My Workplace :)

The University where I worked determined that it was in the best interests of the institution (and the students) to migrate to LibreOffice.  This happened in 2011, but the process was slow.

In the school where I work, the migration stalled, mainly because of the resistance of professors.

An email from the direction of the school made my day today.  It read that the migration was in process and that all computers in the labs (and the laptops) had been migrated to LibreOffice.

I cannot be happier.

Weekend fun

I braced myself for a weekend marked by work.  So, I turned on my ZaReason Strata laptop and left the room to get a cup of hot tea.

When I returned, I found Lara, my cat, playing with the keyboard.



This is the only "cyber-attack" that I have suffered since I migrated to Linux... And I have to admit that it is, by far, the cutest!

From .flv to mp3 with Firefox add ons

Sometimes I need to get the audio from a video in YouTube, which I download using Download Helper, the convenient Firefox add-on.

Normally, I prefer to do the process myself: that is, I extract the audio with a program (VLC) and then use Audacity to convert the file to whatever audio format I  like.  The advantage of this approach is that I stand on my own feet and can get my .mp3 file all the time and the way I like it.  The downside is that, depending on the distro I am using, I might not have the tools available.

If you do not know how to use those tools (or ignore how to use the Linux terminal to achieve that purpose easily), you can always take a point-and-click approach to convert .flv videos to .mp3 files thanks to a Firefox add-on called BestVideoDownloader 2 (you can get it here).  This add-on relies on a transcoding Web service called converttomp3.net.

Once you have installed BestVideoDownloader 2,  go to your desired YouTube video, play it and scroll down to look under the title.  Right next to the like/dislike buttons, you will see the downloading icon of BestVideoDownloader 2.
 
 Click on it and a drop-down menu with format options will appear.  Select the one you prefer.  I used MP3 192 Kbps:
Once you select the format, you will see a button indicating that you can proceed to the download service:


You will be taken to converttomp3.net service, which will indicate that the conversion of the file is in progress:

The conversion will finish and the service will ask you to specify the .mp3 file tags.  Simply click on "CONTINUE": 

This will take you (finally!) to the download page.  Notice that the service will only store your .mp3 for two hours.


This process is certainly convenient, but it has a main drawback: you depend on the service to be up and running for your conversion to work.   Another potential problem can be that, depending on the version of Firefox that you use (or if you update the browser in the future), the add-on might stop working until it catches up with the browser version.

OpenMandriva Lx 2014 and iBus, Success Still Eludes Me

The quest to make iBus work with OpenMandriva has been a difficult one.  I first tried to see if I had all the required dependencies according to this page:

    anthy
    GConf2 [*]
    ibus [>= 1.2.0]
    libanthydic.so.0()(64bit)
    libanthy.so.0()(64bit)
    libc.so.6()(64bit)
    libc.so.6(GLIBC_2.14)(64bit)
    libc.so.6(GLIBC_2.2.5)(64bit)
    libc.so.6(GLIBC_2.3.4)(64bit)
    libc.so.6(GLIBC_2.4)(64bit)
    libpython2.7.so.1.0()(64bit)
    python(abi) [== 2.7]

I discovered that I missed a couple.  Most of them are already installed.  However, even having all of them, iBus refused to launch. 

I followed the instructions on this page to activate iBus:

$ pkill -9 ibus
$ ps -ef | grep ibus
$ /usr/bin/ibus-daemon --xim &

The last command activated iBus, but it did not remember the IME selection (Japanese, Anthy).  

The page also said this, which I did not understand:

After ibus-daemon is invoked, Run ibus-setup to set the preference, enable input methods, also start ibus daemon.
e.g.
 $ ps -ef | grep ibus
foo 15735 15518  0 11:30 pts/3    00:00:17 /usr/bin/ibus-daemon --xim
foo 20037 15735  0 12:58 pts/3    00:00:00 /usr/libexec/ibus-gconf
foo 20039 15735  0 12:58 pts/3    00:00:06 python /usr/share/ibus/ui/gtk/main.py
foo 20041     1  0 12:58 pts/3    00:00:00 /usr/libexec/ibus-x11 --kill-daemon
foo 20042 15735  0 12:58 pts/3    00:00:01 python /usr/share/ibus-anthy/engine/main.py --ibus
 
So, that's as far as I have gotten now...
 

Want to Install OpenMandriva Lx 2014? Some Things You Need to Know


OpenMandriva Lx 2014 was recently released.  I had three installs of OpenMandriva Lx 2013 and, to be honest, I was not convinced to upgrade the systems (one desktop and two laptops).  After all, the previous released did pretty much what I needed and I did not want to ditch SimpleWelcome and use Homerun, the new default in OpenMandriva 2014.

When I learned that it is possible to change Homerun, I decided to install the distro.  Interestingly, not using Homerun proved to be a smart move for me.

The Partition Problem

This is how my OpenMandriva Lx 2014 desktop looks right now.  I placed the ROSA Rocket bar panel on top and as auto-hide.  I also added Cairo Dock at the bottom:
OpenMandriva 2014 running on my ZaReason Strata Laptop: workspace 1
As expected, when you click on the ROSA SimpleWelcome, you get this:

ROSA SimpleWelcome on OpenMandriva Lx 2014

The Timeline on OpenMandriva Lx 2014
Now, here's the interesting part.  When I installed the distro, I first tested Homerun.  I discovered that, if you have a multi-boot system, Homerun acknowledges the presence of your other partitions, but refuses to open them. 

For example, when I tried to access my home partition in Mageia, this is what I got.

The path indicated is correct, but the contents displayed correspond to what I have in my freshly installed OpenMandriva Lx 2014 /home.


I tried it once again, this time with my home partition in PCLinuxOS:

As you can see, the path indicates that you are in home_PCLOS (the tag of my /home in PCLOS), but the contents you see are exactly the same that Homerun displayed for the home partition in Mageia...that is, the contents of /home in OpenMandriva Lx 2014.   This happened in both laptops and the desktop.



I then switched the interface to KDE launch to see if it was a generalized problem with the desktop environment.





KDE launch uses Dolphin to open up the contents of your other partitions.  There was no problem whatsoever accessing my files with Dolphin from the KDE launch interface.

The ROSA SimpleWelcome interface does not show the strange behavior displayed by Homerun, either.

The Repository Problem

The other interesting problem I discovered had to do with the repositories.  After I finished my installations, the first thing I did was to update the system.  OpenMandriva Lx set the repos, so I just ran the control center and clicked on update.  There were several packages found, so I installed them.

Once I did this, I tried to install Steam and Skype.  All I got was a message telling me that a fatal error had occurred and that the mirrors were not available.  I set then some FTP mirrors manually (the main32 repo was absent) and tried to install Steam and Skype again.  The answer this time was also negative, but because of missing dependencies. 

The solution was to re-install the OS to all three machines.  Right after completion, without updating, I could successfully install Skype and Steam.

Other Problems: Wi-fi, Printer, Japanese IME

On my HP Pavilion laptop, OpenMandriva picked up the Wi-fi out of the box.  The story was different on my ZaReason Strata.  I had to use a cabled connection to get to the repos and downoad the appropriate package, which did the trick.

Regardless of my many attempts, I could never get my Epson Stylus TX 200 to print.  I mean OpenMandriva 2014 configures the scanner out of the box, but the printer is simply missing.  I installed the driver manually and, even so, nothing has happened.  UPDATE:  I finally made the printer respond.  It turns out that OpenMandriva Lx 2014 does not like the Stylus TX200 drivers I use in Mageia.  So, I downloaded the printer driver (epson-inkjet-printer-escpr-1.4.0-1lsb3.2.x86_64.rpm) from here and that made the printer work.

Last and sadly, success has eluded me trying to get iBus to work on OpenMandriva Lx 2014 so far.  This was not new; the same was true of the previous OpenMandriva release.

Conclusion

I guess that the main question is: after seeing those problems, do I intend to keep OpenMandriva Lx 2014?

The answer is yes.  I find the distro responsive, beautiful, and functional for pretty much all I need (except printing or typing in Japanese so far :-P ).

Those, however, are very specific problems that other users should not expect to find, I suppose, and I can live with them.

OpenMandriva Lx is a very nice distro.  You can read a good review by Prashanth here.

Maxthon, the New Browser on Linux Land

A while ago, a piece of news that stirred interest on the Linux community was the porting of Maxthon to Linux.

Maxthon is a browser.  I knew of its existence a while ago, when I learned that one of the kind readers of this blog used it to display one of my entries.

I visited Maxthon's main page, but was disappointed because the browser was (if a recall correctly) based on Internet Explorer and, as I had anticipated, did not support Linux.

So, I lost all interest on this browser altogether.

But then came the news that Maxthon now supports Linux.  Again, interest sparked and I visited the page again expecting only .deb packages for Ubuntu.

However, I was pleased to see that they also offered .rpm packages.  I accepted their EULA (Maxthon is NOT free software) and installed the .rpm to both my Mageia 3 desktop
and laptop.

The installation was simple and straight-forward.  I was almost ready to find out what a "cloud browser" is.

When I fired up Maxthon, a Chromium-reminiscent browser took the screen.  Yes, Maxthon looked extremely similar to Chromium.  In fact, it identifies itself as Chromium, not Maxthon, which is a problem because you cannot use certain services on the main page:  it says that you must have Maxthon to be able to use them (?!)

The browser claimed to be fast.  I did not see that speed until I registered a Maxthon passport account.   Once you do that, the browser rewards your activity, your completion of personal information, loading up of a picture, etc.

To be honest, the idea of the the benefits of a cloud browser still eludes me.  Yet, I am glad to have another option for browsing the web.

The HP Pavilion Laptop is Back

My poor HP Pavilion, which had a video problem when I was using it, was finally repaired.

I took it to the repair shop the first week of February and they gave it back to me last Thursday... after almost two months.

When they gave it to me, the video display was fixed.  However, when I tried to play a DVD for my daughter, the DVD drive would not read any disc, so I took it again to the repair shop last Friday morning.  In the afternoon, I received a call and the HP laptop was finally operational in all senses.

Well, almost ALL.  It turns out that, after not being able to update the OSs, my rather old PCLinuxOS install got frozen in time.  PCLOS is a semi-rolling distro and you are advised to update it at least every two weeks.  Obviously, after two months, the machine cannot even get the repos.

I will have to migrate it to a newer version of PCLOS.  But I will do that during Easter.  The thing is, I am not sure if I want to do it.  The current install of PCLOS has everything I need to work and play (it even runs the game Braid on Desura), so... why fixing it if it is not broken? 


I upgraded Mageia and OpenMandriva Lx without any problem.

It is good to have this soldier back with the troop.
