    Freedrum on Linux

The recently released Freedrum has no official Linux support. But, fortunately, it uses standard Bluetooth LE MIDI.
It doesn't seem to work out of the box, yet (on Ubuntu 17.04, most probably Ubuntu 18.04 will support it directly).
Bluez 5.46

One really needs bluez 5.46 or higher. On Ubuntu, these are packaged in artful proposed (amd64). Unfortunately, MIDI support is not enabled in this build (Ubuntu bug #1713017).
So you'll need to download the sources, install dependencies plus libasound2-dev, build and install resulting debs. You may need to add --enable-midi to debian/rules. Like this:

                Run OpenLabeler with system Java
              
          
    OpenLabeler is a pretty nice image annotation package,
but I had issues getting it to run. Plus I'd rather use the system-supplied Java environment, instead
of a bundled one, and install it for a user (not in the system).
This happens on a Debian or Ubuntu system (with apt and deb tools available).

Download deb package of latest release.
Extract its contents: dpkg-deb -x ~/.local/openlabeler openlabeler-1.2.0.deb
Make sure you have OpenJDK 11 installed plus apt install libopenjdk-11-jre libopenjfx-java
Cleanup directory structure: cd ~/.local/openlabeler &amp;&amp; mv opt/OpenLabeler/* . &amp;&amp; rmdir opt/OpenLabeler opt

                Seasonality in foods, international data
              
          
    Buying fruit and vegetables in-season makes a difference in sustainability.
What information is there on this, also internationally? Eventually it would be
nice to provide this in a common format, so that you can give your country,
and find what food products are in-season.
Below are some seasonal calendars. Most are a calendar with what fruits, vegetables
(and sometimes other foods) are in-season, per month or per season. This is often
tied to local availability. If greenhouses are used to grow, the local option may
not be the most sustainable one, only Milieu Centraal appears to talk about this.
