Powerline is a “statusline plugin for vim, and provides statuslines and prompts for several other applications, including zsh, bash, fish, tmux, IPython, Awesome, i3 and Qtile”. It looks this cool (this is the most simply form):
In combination with ZSH, it becomes an extremely powerful -and beautiful- tool.
To quickly install just Powerline for the bash:
sudo apt install powerline powerline-fonts
Add the following at the end of ~/.bashrc:
if [ -f /usr/share/powerline/bindings/bash/powerline.sh ]; then
If you want a file manager with column navigation (macOS-alike) in linux, Pantheon File Manager is probably the best option. Pantheon File Manager is part of the Pantheon desktop, developed for elementary OS using Vala and the GTK3 toolkit. In Ubuntu and derivatives (e.g. Linux Mint) it’s as easy to install as:
PPAs are extremely useful, making installing and maintaining apps in Ubuntu and derivatives (such as Linux Mint) extremely easy. However, upgrading the system or problems/changes in the maintainer of the PPA can turn things into a pain the neck. Y PPA Manager is a tool from Web UPD8 designed specifically to keep all this under control in a easy way.
Some of the functions are:
List the packages available in a PPA added on your system
Download packages from PPAs without adding them
PPAs backup / restore, along with all the PPA keys
Update single repositories using a command line tool (by the way, when you add a PPA using Y PPA Manager, it’s updated without updating all the software sources) called “update-ppa” – usage example: “sudo update-ppa ppa:webupd8team/java”
Some options that should help you re-enable the working PPAs when upgrading to a newer Ubuntu / Linux Mint version
Remove duplicate PPAs
Unity quicklists / optional AppIndicator
Installing Y PPA Manager is as easy as copy and pasting the next lines:
We know that feeling. The maintainer of a repository changes something and suddenly we start having problems with the GPG Keys. In my case, this happens -too frequently, under my point of view- with QGIS. Luckily we can fix invalid GPG keys with a single-line command:
Having a dual-boot machine with Windows 8 or Windows 10 and Linux is frustrating, because Windows changes continuously the UEFI booting order, thus preventing GRUB to load. This usually happens after an update.
This command executed from Windows’ Command Prompt (as an administrator) seems to fix the problem for Ubuntu and derivatives:
MEAN.JS still needs to pulish a few things. For example, the compatibility with NODE 7.x. But a part from that, there is the CRUD Module Sub-Generator, which fails to properly add entries to the menu, and it is something that should be working out of the box.
Basically, you can use this generator for automatically creating the files needed for a CRUD interaction, but if you choose to add an entry to the menu… The website stops working and the only thing you can see is a blank page.
I was able to find more people with the same problem, for example:
One day, they tell you that you have cancer. Your life changes. Then, while fighting against it, you go blind. In just 24 hours you can’t see almost anything. However, that’s not stopping you to reach your dreams. This is the story of my friend Rafael Cantos, and in this article he tells us how he, a person with a huge visual impairment, manages to code. Because he, a person that managed to have a title in Computer Sciences, and a masters in the same field, even dealing with a huge visual impairment, is discovering how the real challenge lays in overcoming prejudices.
The article is in Spanish, but Google Translator can help you with that.
It happens continuously. We have a server with no graphical interface, and our disk quota is gone in God knows what.
We could use different commands to identify the source of the problem, roll perception checks, roll will checks… Or we can use NCurses Disk Usage. Beautifully simple, it fulfils more than correctly this task.
