Comments on the oTree Virtual Machine Image and OVMM

[BonnEconLab]

• oTree Virtual Machine Manager version: DON’T KNOW — Maybe add command “ovmm version”? (addressed in Major cli overhaul, add skip nginx_config during initialisation #102 )

oTree Virtual Machine Image:

• Set video RAM to at least 16 MByte to support higher resolutions. (Automatic resizing of the VM window worked when I set the VRAM to 32 MB.)
• 2 CPU cores by default.
• Conky positioning should be adjusted on-the-fly when the resolution/windows size is changed.
• Font in Conky should be monospaced. Decimal period instead of comma.
• Add “construction site” emblem to the “Projects” folder.
• Relabel the buttons in the “collectstatic” message.
  • Change text.
• Include an “empty app” to be shown on the oTree demo page.
• Conky: use monospaced font; replace decimal comma by period; make position depend on CURRENT screen resolution.
  • not feasible.
• Window regarding creation of a virtual environment: Add explanation that this would enable installation of several oTree versions in parallel, one per project.
• “Link Experiment” script: Change text so that “project folder” is replaced by “project (which is usually a subfolder of /home/otreeadmin/Projects/)”.
• 3 tabs/windows that open when Firefox/Chromium starts: otree.org, localhost, http://otree.readthedocs.io/en/latest/
• export OTREE_PRODUCTION=0 or 1 should be set on the fly instead of hardcoded; same for OTREE_AUTH_LEVEL?
• /home/otreeadmin/Templates/_rooms/econ101.txt should include leading zeros.

OVMM

• In the help file of ovmm, the “experimenter” and “user” are used as synonyms, which is a bit confusing.
• User name: [max] is really confusing. It’s not clear that this is supposed to be an example. Moreover, the user name has to include at least 6 characters — hence, “max” is too short.
• ovmm add_user HAS TO BE preceded by sudo.
  • Mentioned in the docs
  • https://stackoverflow.com/questions/2806897/what-is-the-best-practices-for-checking-if-the-user-of-a-python-script-has-root with os.geteuid()

ovmm add_user

is executed and at then end asks for the sudo password. The command fails, however. See attached screenshot.

• nginx_template: Rephrase the instructions on how to set up HTTPS instead of HTTP.
