Data sets from my dissertation

This past week I successfully defended my doctoral dissertation. Two of the three direct numerical simulation data sets I generated during my thesis research are online at turbulence.ices.utexas.edu if anyone's interested:

Sub- through Supersonic Coleman-like Channels

I finally cleaned up my compressible, turbulent channel results computed with my thesis code, Suzerain. The dataset includes instantaneous planar averages of 180+ quantities collected in situ during the production runs along with rigorous sampling error estimates for the final ensemble results.

If you want to quickly visualize something, a little wrapper utility makes it a snap. So, without further ado, gratuitous eye candy generated with summary_surf.py -C 256 -f coleman3k15.h5 bar_u_v bar_u bar_v:

Installing Chromium under $HOME on RHEL 6-ish x86_64 systems

Based upon Install Chromium (with Pepper Flash) on CentOS/Red Hat (RHEL) 6.5 with modifications to permit non-root usage...

mkdir ~/workaround && cd ~/workaround
wget http://people.centos.org/hughesjr/chromium/6/x86_64/RPMS/chromium-31.0.1650.63-2.el6.x86_64.rpm # 32-bit seemingly in repo too
rpm2cpio chromium-31.0.1650.63-2.el6.x86_64.rpm | cpio -idmv
./opt/chromium-browser/chromium-browser # Bombs on sandboxing complaints
./opt/chromium-browser/chromium-browser --no-sandbox # Confirm behaves for you
mv ./opt/chromium-browser ~ # Moving the whole directory into a permanent location
echo '#/bin/sh' > ~/bin/chromium-browser # Assuming you have ~/bin in your path
echo 'exec $HOME/chromium-browser/chromium-browser --no-sandbox "$@"' >> ~/bin/chromium-browser
chmod a+x ~/bin/chromium-browser
chromium-browser http://www.google.com & # Rejoice
cd && rm -rf ~/workaround # Hygiene

The are glaring drawbacks to running Chromium with --no-sandbox so don't do it without considering its implications.

Twelfth

A fun holdover from the days when I was last gainfully employed-- the 12th patent on which I'm part inventor was issued earlier this month: Converged call flow modeling and converged web service interface design.
