Configuring a space mouse was way harder than it should have been. Here is the way to reproduce a "working" version.

Step 1

Ignore the proprietary driver at 3dconnexion and the open source ones from spacenav. They are useful for custom programs, but useless for paraview which currently uses VRPN to lower their maintenance.

Warning: VRPN does not work if you have one of the drivers running at the same time.

Bare mirror the repository (using example urls)

$ git clone --mirror git://example.com/some-big-repo.git

Mess with the repo (this one removes big files)

$ java -jar bfg.jar --strip-blobs-bigger-than 100M some-big-repo.git

Once you are done with cleanup it will gve a message about cleaning things up. This boils down to expiring the reflog and garbage collecting

Example 1

SNSPowderReduction is the workhorse algorithm in mantid that was built to reduce data from POWGEN. It is used inside the GUI used for reducing data as well as in autoreduction. The underlying algorithms were made both to aid in testability, but to promote reusability. The child algorithms listed are not by any extent all of the child algorithms that are used. Instead they are the ones that I was, at one point, a majority contributer to.

• SNSPowderReduction (test, user docs) takes a collection of event nexus files, instrument calibration, and one or two c

On rhel7 (which is based on f19/f20), qt5-qtbase moved from 5.6.1 to 5.9.2. This broke upgrading Naively I tried to rebuild a bunch of things thinking it would be "easy."

Much of this information was determined from digging through https://rpms.remirepo.net/rpmphp/

Currently:

• sip 4.18 from f24
• python-qt5 5.6-6 from f24 (best guess)
• PyQt4 4.11.4-14 from f24
• python-ipython rebuilt from rhel7
