kure | a flat-file blogging engine

I have a PostgreSQL table of Czech words (>1M rows) with a column named "word" [text] and I want to find all words with the same declination (see Czech declination) based on the word ending.

E.g. I want to find all words that end with "e" (e.g. kuře), but for which also exists word forms that end with "ete" (e.g. kuřete) and also "etem" (e.g. kuřetem) and also "eti" (e.g. kuřeti). For each word exists approx. 14 word forms.

What is an efficient way (SQL query) to find all words that match the rule?

From here, I could find that the linux nodes are automatically updated daily. Does the container runtime also getting updated to the latest one? Or do I need to manually updates the container runtime?

Using R, I aim to write a piece of code that would look into dataframe named df, check cell value in column IMG, and open a .jpg raster from another folder whose name would match IMG (plus the jpg extension).

Ultimately I would want the function also to calculate the number of black pixels in that image and save the result in either a new dataframe (with the IMG/filename included in one column, and number of black pixels in another), or to the old dataframe df in a new column and in corresponding row.

I can't figure out how to even start, and thus I have no even remotely functioning code yet. I know how to write very basic loop functions, and I believe I will be able to get the code finished if someone would direct me to the right direction...

Here is the dataframe from which I would like to check the file names. There is altogether 300 rows and thus 300 images, so while it would be doable manually too, it would take a lot of time and I am rather intrigued how this would be done by code.

When i start the command, in console i see the error:
