Grid -> 2-dimensional layouts
That being said, I use Flexbox for pretty much everything.
Flexbox -> Content first, Layout second.
Grid -> Layout first, Content second.
To make my database fast, I often have to do a vacuum full on some key tables. Which is basically a freeze all access to the table, and copy byte by byte to a new physical file. So as your data size doubles, the vacuum full time doubles. Have a table that is so big I basically can't vacuum full it anymore (in an acceptable amount of downtime).
Hot reloading (to the extend that change-save-refresh would feel like working with a python/ruby projects), shallow stack traces, less 'magic', , excellent documentation, plethora of modules, less memory footprint, milliseconds start/restart (owing to compile time wiring), first class container support, dev tools, always running tests are few that makes DX with Quarkus amazing.
I tried to read as many non-fiction books as I could, but these were almost non-existent in the jails I was housed in. The ones I got sent in about business and languages were a god-send and I find the information I gained from those to be very useful to me; especially the books on Japanese and Arabic which gave me a great grounding in those languages, although you can't easily learn pronunciation from a book!
