1. # Replacing dead links for the Dutch Royal Library (Koninklijke Bibliotheek)

This is mostly a set of notes to allow others to perform these replacements as well. They are written for the specific case of the KB, but should be applicable to URL replacements in general.

The original requests can be found at 1 and 2.

Requirements:

• a working pywikibot installation ...
2. # Using LiveReload with Pelican

LiveReload is magic. As the authors describe it:

The Web Developer Wonderland

(a happy land where browsers don't need a Refresh button) -- LiveReload

What does it do? It's a browser plugin that automatically refreshes a page when the server tells it to. On the other side, we have ...

3. # Building a Flask project with OAuth enabled on Tool Labs

This is a guide to building a simple Flask project on Tool Labs. Tool Labs is the Wikimedia shared hosting project, for projects ('tools') related to Wikipedia or one of the other Wikimedia projects.

This guide assumes you have a Tool Labs account and some knowledge of getting around. The ...

4. # Adding a colormap to a figure without imshow/countour set

Example: plot a packing using circles, and use the foreground color to show some value for each particle, for example the contact number Z:

The trick to this is to call plt.scatter() to plot a single point outside the axis range. This allows plt.colorbar() to find cmap and ...

5. # Rearrangements and plasticity in two-dimensional sheared foams

In collaboration with Vera Janssen, Alexander Siemens and Martin van Hecke

We experimentally apply a slow pure shear deformation to a quasi-two-dimensional foam under glass-liquid boundary conditions. In contrast to earlier research, which focussed on the behavior of dense systems, we investigate the behavior close to the jamming transition.

6. # Rearrangements in Jamming

In collaboration with Johannes Simon, Zorana Zeravcic, Simon Dagois-Bohy, Brian P. Tighe and Martin van Hecke

In the last decade, computer simulations have been used to gain insight in the behaviour of granular matter. This has allowed a description of the behaviour for small deformations. In this project, we are working on what happens beyond small deformations. read more
