Formulae in LaTeX
The input of math, physics and computer science formulae has long been a chore. But now it is ... still a chore for those who don't know how to write formulae using the document markup language LaTeX. And simple for those who do.
Just enclose the formula you want to show up in a flashcard, note or comment by
{$ ... $}and it will render neatly. For an overview of the most common used symbols see Wikipedia.A few examples:
This ... Renders as ... {$ \omega $}
{$ 2 + 2 = 5 $}
{$ a^2 + b^2 = c^2 $}
{$ \frac{1}{x} $}
{$ \sum_{i=1}^{n} \left( \frac{1}{r} \right)^{\ell_i} \leq 1. $}
{$ \Omega = \sum_{p \in P} 2^{-|p|}. $}
{$ \left\lfloor \mathrm{mod}\left(\left\lfloor {y \over 17} \right\rfloor 2^{-17 \lfloor x \rfloor - \mathrm{mod}(\lfloor y\rfloor, 17)},2\right)\right\rfloor $}

Update August 2006
During the last few weeks I enrolled in Cognitive Science at the University of Osnabrück, got attacked by E.Coli bacteria and found a nice flat in Osnabrück. I have changed a few details at Mindpicnic but nothing major.
Talking about my flat: Google Sketchup is a great piece of design software. Even people like me who haven't done any 3D modelling can draw a model of their house and add furniture easily.
I have a few days left before looking for real furniture will take up all my time. I'll try to fix the most important bugs and hopefully get to add some new functionality. As always: Send your wishes for new features and other changes to andreas@mindpicnic.com or post directly into our ticket tracking system.

Edit flashcards from learn mode
Most of the time it is during learning when I discover a mistake in one of my flashcards. Nonetheless I have always been against including some kind of edit link in Mindpicnic's learn mode — the learn mode should offer as little distraction as possible.
Today Robin reminded me that it would in fact be a nice thing if there was an easy way to correct mistakes instantly. Here's a compromise: From now on there is a "edit flashcard" link during learning. The link is hidden until you double click on the answer of a flashcard.
