xterm forgets configuration

Date Tags xterm

While trying out xterm, I noticed that it forgets its config between reboots. As pointed out on AskUbuntu, the solution is to link .Xresources to .Xdefaults-HOSTNAME

cd ~; ln -s .Xresources .Xdefaults-$(hostname)

Goodbye source/VENV/bin/activate

TL;DR: run pip install --user vex and vex --path venv* $SHELL

Yaml fixture with ManyToManyField in Django

The official docs explain how to set up “natural keys” for easier writing of fixtures.

The things to remember are basically two:

  • setup a models.Manager (write the class with an appropriate get_by_natural_key method and instantiate it in the managed class)
  • the fields used for a natural key must be ...

notes on developing with Cmake projects

Problem

The library provided by your distribution is old and you want to link your program to a more recent version.

Furthermore, I assume both the library you need and your program employ CMake as a build tool.

PKGBUILD for Avogadro local testing

Since I’m writing some extensions to Avogadro, I find useful having a PKGBUILD for creating a package on Arch Linux.

Here it is

pkgname=avogadro-devel
pkgver=$(git describe --long --tags | sed 's/\([^-]*-g\)/r\1/;s/-/./g')
pkgrel=1
arch=('i686' 'x86_64')

A messy BTRFS recovery

cryptsetup open /dev ...

automatically activate python virtualenv in pycharm

I slightly modified an answer from stackoverflow to make it work on linux

nano ~/.pycharmrc
if [ -r ".pycharm/term-activate" ]; then
   source ~/.bash_profile
   source ".pycharm/term-activate"
   source $PYCHARM_VENV/bin/activate
fi

On your project folder, assuming you have a virtual environment called venv35,

mkdir .pycharm
nano .pycharm/term-activate
