I've finished this week's New European, my dose of comforting confirmatory bias that leaves me angry, almost satisfied and a feeling of intellectual and cultural superiority to 'them'.
This may not be a Good Thing.
But realising it is at least sane.

A problem with the Stack Exchange Data Dump is that it's an unwieldy pile of XML files.
I wrote a script to process it down into SQLite databases with basic indexes to make it more usable out of the box. Just finished uploading it to the Internet Archive

Abstract: In this paper, we prove a theorem concerning the existence of three solutions for the following boundary value problem: \begin{equation*} -\mathcal{M}_{\lambda,\Lambda}^ (D^2u)-\Gamma|Du|^2=f(u)~~~\text{in}\ \Omega, u=0~~~\text{on}\ \partial\Omega, \end{equation*} where $f:[0,\infty]\to[0,\infty]$ is a $C^{\alpha}$ function and $\Omega$ denotes a bounded, smooth domain in $\mathbb{R}^N$. By constructing two ordered pairs of sub and supersolutions for a specific class of $f$ exhibiting sublinear growth, we further establish the existence of three positive solutions to the aforementioned boundary value problem.
