For about language learning and spaced repetition, things are running.
Just cup of days ago, Ukrainian government decided to make English a must for officials, and made changes to education regulations, so now English will study from first year in all Ukrainian schools.
Spaced repetition, from my own experience, is very depend on how well organized person, and war making huge interference in organization. Imagine, how hard to organize if you every day hear siren of air defense, and nobody could predict, how long war will last, and every day possible some extreme news.
To be honest, I envy to Yugoslavians, as they war last just few months, NATO aviation very fast finished Soviets offense. In Ukraine case, I literally seen few tides and ebbs, when things slowly become more extreme, and then again, slowly return some stability and feeling of safeness.
And the last what I must say, Ukrainians are good in peer interactions, unfortunately at the moment, we have not good reliable results in large scale peer interactions, I think we must study this part of democracy.
I think, my other answer also could say something additional: https://www.hackerneue.com/item?id=38503774

For the metaphorical warmer, something that could help people that you could probably help with as a programmer is a language learning platform: If people need to leave the country, knowing how helpful spaced repetition can be might save them a lot of strife.
If networking in your region becomes unreliable, it could be useful and helpful to know about mesh networking, but for that to be effective, cooperation needs to happen between multiple parties in different locations, and that can be difficult.
