I did the unthinkable and upgraded my OS (in my final year of my PhD!). And surprise-surprise, some of my code wouldn’t compile anymore. I figured I needed to rebuild my macports-installed *nix software but ran into problems with gcc45 and libstdcxx. The issue is a ld64 bug, that was fixed using user adrian’s solution (replicated here):

sudo port uninstall ld64
sudo port -v install ld64
sudo port clean libstdcxx
sudo port -d build libstdcxx build.jobs=1
sudo port install libstdcxx

A little exhausted after a couple of paper submissions to IROS. Looking forward to a break for a few days while I re-organise and re-think. And some opportunity for reading (Kantz and Schreiber’s Nonlinear Time Series Analysis that I bought ages ago but haven’t finished, and Chaitin’s Meta Math that I have read but have largely forgotten).

Plus, my desk is clean again!

Just testing some $\LaTeX$. Some of the world’s most favourite equations:

$\nabla \cdot \textbf{D} = \rho \\ \nabla \cdot \textbf{B} = 0 \\ \nabla \times \textbf{E} = \frac{\partial \textbf{B}}{\partial t} \\ \nabla \times \textbf{H} = \frac{\partial \mathbf{D}}{\partial t} + \mathbf{J}$

$\mathbf{F} = m\mathbf{a}$

$a^2 + b^2 = c^2$

$H\psi = E\psi$

$E = mc^2$

$S = k \ln W$

$1+1 =2$

$\delta S = 0$

$p = \frac{h}{\lambda}$
