Cleaning cruft in a Ubuntu installation

Tormod — Sat, 18 Feb 2017 14:19:00 +0100

I have been running Linux on my laptops for as long as I have been owning laptops. My current one has been through quite a few versions of Ubuntu Linux. There are normally no big changes from version to version, but it steadily improves. In that process some software packages …

3D visualization in IPython notebook

Tormod — Fri, 23 May 2014 22:18:00 +0200

The IPython notebook is a great tool for interactive computing. Below I show a short Python example on how to work interactively with simple 3D models in the IPython notebook.

To begin with, we need a simple way to represent a 3D model in Python. We will here restrict ourselves …

A linear 2D sloshing solver in FEniCS

Tormod — Wed, 29 Jan 2014 20:29:00 +0100

In the previous blog post I showed how to solve the Laplace equation in 2D with FEniCS. That example, while illustrative for how to use FEniCS, was not particularly exciting. So, I decided to show the simplest example I could think of that involves an actual example of fluid flow …

Solving the Laplace equation with FEniCS

Tormod — Mon, 13 Jan 2014 21:45:00 +0100

I have found that explaining something is a good way to learn. As I am currently reading some books on the finite element method to refresh my rusting memories from math courses at university I thought it would be a good idea to write a summary of some of the …

Creating a mesh in FEniCS

Tormod — Sat, 11 Jan 2014 18:00:00 +0100

I may end up doing a large project using FEniCS which is a collection of tools for automated, efficient solution of differential equations using the finite element method. While playing with implementing a simple solver for fluid flow in a tank by use of FEniCS to solve the Laplace equation …

Sorting images

Tormod — Sat, 04 May 2013 23:50:00 +0200

Once upon a time, back when I was using Windows at home, I had a useful small program that helped me sort through new pictures from my camera. I have forgotten the name of the program, but basically it allowed me to sort the good pictures from the bad in …

Full screen music info

Tormod — Fri, 24 Oct 2008 21:35:00 +0200

I've written a short program to show the currently playing song in a full screen view to avoid having to walk over to the computer when I want to know what the current song is called. The Squeezebox has mostly made this obsolete as I now just look at the …
