Below is assorted software-related stuff and pacthsets which never got into upstream. Primarily for my own use, but feel free to grab whatever you wish.

Working gimp-python for Debian 11 (Bullseye)

Diagnostic hallmark of problems with your favourite scripts – Gimp's screaming on the console about wrong python version of missing gimpfu import. The reason behind is that bullseye dropped python2 and Gimp does not know python3 yet, therefore maintainers dropped gimp-python package, which provided API for pythonic scripts.
These instructions made my python scripts (esp. python-fu) work again with Gimp under Debian 11 (bullseye). It's not bulletproof your scripts might use more broad set of functions. Note also that these are not instruction for newbies - they can break other things in your distro later - namely having python2 as default and mixing python-pkg-resources version from buster is invitation for troubles. So you should do it only if gimp-python scripts are absolutely necessary and you know what you are doing or how to fix forthcoming problems. You have been warned...
  1. Make "python" command available again/set it to python2 by choosing from these candidates:
    apt-get install python
    apt-get install python-is-python2 
  2. Download from packages.debian.org the buster version of .deb files below (amd64 is here for my convenience, you should not probably trust anonymous binaries from here ;) Then install them (ordering matters, also no guarantees that some additional deps from *bullseye* aren't missing, I was not working from vanilla system).
    dpkg -i libffi6_3.2.1-9_amd64.deb
    dpkg -i python-gobject-2_2.28.6-13+b1_amd64.deb
    dpkg -i python-pkg-resources_40.8.0-1_all.deb #bullseye will try to update this one later
    dpkg -i python-numpy_1.16.2-1_amd64.deb
    dpkg -i python-cairo_1.16.2-1+b1_amd64.deb
    dpkg -i python-gtk2_2.24.0-5.1+b1_amd64.deb
    dpkg -i gimp-python_2.10.8-2_amd64.deb 
If dpkg fails while you experiment, it's good to know about this one: apt --fix-broken install . Bullseye will try to update python-pkg-resources later, in my test update did not broke the scripts here, but YMMV. You can alway use apt-mark hold to fix older version if necessary.

BiBtex style for the journal Cerebral Cortex.

The original file was provided by Rajeev Raizada and was slightly edited to fix small interpunction issues. At this stage it's mainly @article bibtex entry tuned, but you can easily change the rest.

BFS-like movement through directories

Like your 'cd' bash command, except it searches through the directory structure to find the given nearest directory/file. Starts in your current directory and crawls in a wave-like manner through adjacent sup/subdirectories (breadth-first search).
By default
For proper functioning you will need to add lines like the below to your .bashrc (or .profile or similar file loaded by your default shell):
function jp { cd "`j "$@"`"; } 
function jf { eval "`jj "$@"`"; } 
Debian binaries (or sources):
Configuration file .jp in your home will help you to setup excluded names and suffixes in the search.
Commandline examples:
$ jp dir       #cd to closest dir starting with 'dir', e.g. ../dir/i/dont/remember/directory
$ jp dir.      #cd to closest dir containing name 'dir'
$ jp dir=      #cd to closest subdir starting with 'dir'
$ jf fil       #cd to closest dir containing file which name starts 'fil'
$ jf fil/      #cd to closest dir containing file which name starts 'fil' and immediately open it in vi(m)
