#+TITLE: Dimensions of Covid

Fuck this. Millions of people have died of COVID and probably there are millions more to come. Instead of a coordinated effort of keeping the global suffering as small as possible, most of the energy goes towards squeezing the last bit out of collective organization so that already powerful countries can be kept running and get an edge in the post-pandemic economic recovery. Early pandemic hopes that it could lead to a significant and lasting disruption of business-as-usual seem infinitely far away while the abolition of health protective measures is discussed even in regions with hundreds or thousands of people suffering and dying each day.

* What this is about

* How does it work

In regular intervals, =update-data.sh= fetches the current covid data from https://covid-19.datasettes.com, which provides data by the Johns Hopkins university, using the following query:

#+begin_src sql
select day, last_update, sum(deaths) sum_deaths
from johns_hopkins_csse_daily_reports
where country_or_region not like '%Olympics%'
group by day
order by day desc
limit 1
#+end_src

This provides an up-to-date approximation of total covid 19 deaths. In a somewhat backwards manner this is saved in a CSV, which is then again imported into an SQLite database. The database is queried in =index.lua=, where a single HTML page is created as a response.

* Bundling

Just add it all to the [[https://redbean.dev][redbean executable]]:

#+begin_src sh
nix run nixpkgs#zip -- redbean.com *.lua
#+end_src

The executable can just be put somewhere and run, and the update script should be run regularly:

#+begin_src sh
rsync -rztsv --info=progress2 redbean.com sqlite3.com update-data.sh ...
# crontab -e ...
#+end_src

Note that there were some problems deploying the executable to uberspace, which could be resolved by using =redbean-unsecure.com=, which comes without built-in SSL support.
