Using trickle with Flatpak applications

Trickle is a command-line tool to throttle network bandwidth of other applications. You use it on the command-line to start the application. It uses LD_PRELOAD to override network-related calls. As a result, using it with containerized apps, like Flatpak, does not work out of the box.

To get trickle to function with a Flatpak application, the preloaded library needs to be available in the container. And it needs to be compatible with the software in the container (notably, a glibc version that is compatible).

First try

  1. Install trickle on your (host) system, on Debian/Ubuntu that would be apt install trickle.
  2. Make sure you have the flatpak application installed. I'm using com.slack.Slack as an example here.
  3. Run the flatpak application with trickle

Enriching ASFIS with Wikidata or FishBase
#!/usr/bin/env ruby
#
# We start with the list at:
# http://www.fao.org/fishery/collection/asfis
# Then we query FishBase (and SeaLifeBase) for the ID and NL name.
#
# Before running this script, make sure you have the ASFIS spreadsheet,
# and make sure you've created the CACHEDIR directory (which stores all
# requests, so you can run this again without having to wait for the requests).

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.
