week June 5 -- June 11

On Sunday I moved to Livermore.

On Monday I rebased my patches for Euler Equations, DG and FVM for hermes2d, sent for review. Unfortunately it took till Friday until they got reviewed, but they are now in.
I couldn't sleep, so at around midnight I turned on my computer and rewrote the build system for femhub, it took me about 1.5h. Then I could finally sleep well.

On Tuesday I had my new hire orientation. During it I wrote couple more patches for femhub.

On Wednesday I got my badge and spent the rest of the day with paperwork. They didn't manage to get my computer setup, so I studied a bit of Quantum Field Theory from a book that I found in our room and then spent the rest of the night figuring out the weak formulation for the radial Dirac equation. So far no luck, but at least I wrote it in many different forms in my hand written notes. Sometimes it's not bad to be cut off the internet and computers.

On Thursday I got my computer account setup and spent most of the day with paperwork.

On Friday I finally did some real work. Then we got to a pub, got home and drank the rest of my Budvars (Czechvar) and Plzeňs (Pilsner Urquell).

The FEMhub build system is really cool. It's written in Python and I totally got rid of the old Sage build system. Some features of the new one:

* dependencies
* automatically uses all your processors (unless told otherwise)
* simple Python script (414 lines) that handles everything, plus sage-env, sage-spkg and sage-make_relative scripts (the rest I simply deleted)
* allows you to install just some packages, for example "./femhub -i python" just installs python and it's dependencies
* allows you to unpack any package into the devel/ directory and then build it

I will not use it to develop hermes1d+schroedinger and dirac solvers over the summer, so it will likely get improved in the coming weeks. (I have to use it, because my computer is some old RHEL5, and I don't have a root access. With FEMhub, I have all the Python libraries plus cmake and similar stuff right there. It's really awesome.)

In total, I wrote 52 patches for FEMhub, 3 for hermes_common, 9 for hermes2d, 8 for hermes1d and 1 for sympy:
