zsh.li Pinkhat Memories Me About ?

Dear My


Problems burning double layer DVD.

Today my news DVDs of 8 GB arrived, so that, I tried to record my music into one of them; Brasero didn’t worked and asked me for a valid disc. Then I tried to install k3b and I disabled all its USEs, all media features were removed. To tell you the truth I love k3b but it usually includes a lot of stuff, however, since I use Gentoo I can get through this. After that I tried to burn the DVD+R and it failed in the middle of the process twice (16GB of storage space lost ), next I recompile k3b with DVD support and I changed the path of the iso image to my documents instead of my /tmp folder (I think it could have made it fail) , and finally I selected no multi-session and chose the Rock Ridge/Joliet (custom) for it. In the end I achieved to burn it, even though, it didn’t read it. So, I plugged in my external DVD player and finally it was able to read the contents of my just recently burned disc. Here part of the error log: K3b Version: 2.0.3 KDE Version: 4.14.24 QT Version: 4.8.6 Kernel: 4.8.12amu-kernel Used versions ———————– mkisofs: 3.2a06 cdrecord: 3.2a06 cdrecord ———————– cdrecord: Insufficient ‘file read’ privileges.

Gentoo december issues

Dear diary, today I booted up my computer with Gentoo as I wanted to update the kernel and others packages; however when I wanted to update the kernel source code there was a lot of dependencies for only the Linux kernel —It is kinda surprisingly—:

As usual, ICU was blocking my updates and tries of packages installations, also it seemed that ncurses was blocking the update too (I hadn’t seen this before)

However, because I updated my mesa drivers, Gentoo was luckily unlocked as it upgraded 108 packages.

Finally I had another problem with Ruby and Python because Gentoo was using the old versions, so I removed them as this topic suggested:


Also I learned a very useful trick about the console, how to avoid that the shell logs an specific command, just add this to your ~/.bashrc file and that’s all.


So when you do not want Linux to log a command just type an space before the command and after the prompt, and ready!

Recoloring icons to pink

I am still using Linux Deepin, I found it interesting that Linux Deepin includes the Flattr icons by default, however the folder icons are green and It didn’t combined at all, I wanted them to be pink, and so for the first time I achieved to automatically change the colors using a command:

Original icons:

Updated icons

cd /usr/share/icons/flattr/places/64/ sudo for p in folder* ; do convert "$p" +level-colors red, "$p" ; done cd /usr/share/icons/flattr/places/16 sudo for p in folder* ; do convert "$p" +level-colors red, "$p" ; done


The system icons location is /usr/share/icons/flattr , in the places subfolder is located all folders icons wich are available in two different sizes: 16×16 and 64×64. Thus /usr/share/icons/flattr/places/64/ stands for 64×64 sized icons and /usr/share/icons/flattr/places/16 stands for 16×16 icons.

As them are system locations we need to use sudo; in the second and forth line the color of icons are changed from green to pink with the execution of a loop, i.e. using the for command. The for command syntax is similar to this: for a variable in a string ; do something, done ; our variable of course is the letter p and our string is the regex folder* ; our something are the special commands for transform the pictures:

Convert is the cli of the well-know image-magick, the following is the command used for transform each picture:

Trying Linux Deeping

Today was a very funny and exhausting day. I deleted my Arch Linux installation and :c it brought me back nostalgic memories:

To tell you the truth I wanted a simpler Linux distribution so that I could be focused on Gentoo because Arch is also a complex Linux distro.

I tried to install Ubuntu with debootstrap but surprisingly I failed :c , you could say it is surprisingly since I am able to install Gentoo but not so Ubuntu. I was able to install the core system and make chroot, also I was able to install everything with no problems.

The issue was that Ubuntu booted into emergency mode, despite of realizing I had forgotten to add the file system in fstab, fixing it didn’t solved the problem.

The most important thing is that I learned that we have to be careful when using bootstrap to install a distribution and make a list of steps or diagram.

And my main mistake was to forgot the fact that Ubuntu have several repositories D: I was indeed overconfident, it it hard to me to understand how was I able to flawlessly install Debian Sid in the same fashion, Arch and of course Gentoo and failed with Ubuntu :c

Maybe systemd is not enough stable in Ubuntu yet, by the other hand I learned a new concept UTMP, is a kind of special file where every login is recorded. It depends in the symlink in /var/run of /run

Possibly it had to do the improperly unmounting of LVM partitions in Gentoo, now I remember once Arch did not let me boot into until I runned fsck, well, never mind.

What a troublesome init system is this systemd. It seems that getting back to Openrc right in Gentoo was a very wise decision ^o^

After failing to install Ubuntu I tried to install Deepin and it was perfect, it is gorgeous, my dream Linux distro


And now guess what, I also installed deepin in the cli way, to tell you the truth I wanted to do it using a usb flash but I wonder where my pen drive is :c , anyway.

The most challenging thing was to set up the root password, I didn’t know what I was not able to set the root password within chroot, I had to boot with a kernel parameter (init=/bin/bash) in order to set up the root password and so my local user password.

I think it is perfection


And finally I did a backup of my root file-system using the following command:


This will create a tar.7z highly compressed file, I choosed the 7z method since it supports multi-thread compressing -I have 8 threads-, and for the sake of time saving

Public backup of blog

Today I learned how to connect via ftp with my remote hosting and wget ended being perfect while curlftpfs was really bad :c

Today I installed Apache, PHP and set up a WordPress local server to have a backup of my Linux website, also to be able to make this kind of backups.

I think it is very important to make different kinds of backups because it is possible that even the most reasonable and useful backup can fail at the moment.
