A Gartner market analysis The State of Open-Source RDBMSs, 2015 (found via IT World Canada) comes to a conclusion which I like (except for the vocabulary problem): “Open-source relational DBMSs have matured significantly and can be used to replace commercial RDBMSs at a considerable TCO saving.

(The vocabulary problem is that they say “Open Source” where they wanted to say “Free” or “Libre”. I guess that the main reason for this vocabulary problem is that the word “free” also means “free of charge” while “libre” is too new.)
Shekhar was the first to speak me about Paramiko. I did not yet understand why it might be useful for me.
We still need a _startup_done attribute because Django “somehow” imports the settings module twice. I didn’t understand it definitively, but without this we had the startup code being run twice, which caused error messages about duplicate label in workflow setup.

I think that the solution was simply
git checkout master.
Changed Apache configurations so that it serves the static files. I hope that I can serve all static files from one place.
Oops, yet another surprise: the
lino.css file had a hard-coded
expectation that static files are served from /static/. That’s why
we now have
lino.core.constants.ICON_NAMES, a protection
against specifying unknown icon names in
lino.core.actions.Action.icon_name, and these style
definitions are now inserted into the index.html page. (The latter
is a bit suboptimal: we might build a single
lino.css file at
Site startup (like the
And yet another surprise: I finally had to tidy up where the passport
image read from eId cards are stored and how to access them.
This is now done in
Here is also an interesting post which gives more examples of why static files should be managed specially: Stop Using STATIC_URL in Templates
