# Embeds a distance matrix into 2D using MDS. Distances are normalized
# to [0,1] in order to facilitate comparing embedded matrices.

Creating a simple HDF5 test file with a single group and a single simple data set using the `h5py` Python bindings
#!/usr/bin/env python3
# Creates a simple 3x3 HDF5 test file. The file will contain
# a single group and a single *simple* data set. The numbers
# from 1 to 9 will be distributed over the data.
import h5py
f = h5py.File("Simple.hdf5", "w")
d = f.create_dataset("Simple", (3,3), dtype='f')

Workaround for potential issues with NeurIPS 2021 style and newer versions of TexLive. This is *not* an official fix.
% partial rewrite of the LaTeX2e package for submissions to the
% Conference on Neural Information Processing Systems (NeurIPS):
% - uses more LaTeX conventions
% - line numbers at submission time replaced with aligned numbers from
% lineno package
% - \nipsfinalcopy replaced with [final] package option
% - automatically loads times package for authors
% - loads natbib automatically; this can be suppressed with the
% [nonatbib] package option

Counting words in TeX files under version control in order to depict the temporal evolution of the document. Useful for creating graphs such as the one shown in PhD comics #1915,
# This script traverses all commits of a git repository in the current directory
# and counts the number of words that are changed, i.e. added or deleted for all
# TeX files. The output contains a time-stamp (YYYY-MM-DD). Next, there are some
# counts, viz. the number of added, deleted, and total words.
# You can use `gnuplot`, for example, to create nice visualizations from the raw
# data. For this, it may be useful to specify the first column as a date column:

This is a user script (to be used with Greasemonkey, Violentmonkey, and similar packages. It automatically adds a download button for `.bib` citation export to Springer Link publications. Enjoy!
