This was the solid book to get into data science and ML scene. Covers everything. Jake is a fantastic teacher. I really wish he comes up with updated second edition.
I am amateur and more or less an ignorant in programming domain so what I say doesn't matter much.
Why not a pick a language of choice and write some ambitious framework/library? Like Numpy/Pandas for Python. Maybe a web development framework? That way, there is a reasonable chance your work will be noticed or used. Look Maybe pick Julia and write a library for it. I believe Julia doesn't have as many libraries as Python does.
By the way, as much as I know, all the languages were written by 'old' people. Young people rarely have that much knowledge or experience. They don't even know one language fully well. So age is actually at your side.
This sort of overemphasized paranoia about security is something which makes me, I dunno, irritated. If you decide to go to extreme, everything is unsafe but you don't want an old device even as a secondary device?
I'd rather work on my paranoia than on getting a fully secured device.
By the way, I am writing this on a mobile with 2 GB RAM and running Android 9 as my other mobile got broken.
Whatsapp has already started stinking. These days I get many spam-ish messages from verified enterprises. As of now I am getting notification related messages from entities I am using services of but some of them have started sending spams. Although it is tolerable as of now but I can see where this is going. Too bad Whatsapp is defacto messaging app in India. So much so that even gov organizations are using it to interact with citizens.
I am 40 yrs old and English is my second language. I cant give you some specific examples but when I watch old hollywood movies (50-60s), I mostly understand dialogues. Dialogues from modern movies are a bit harder to understand and I cant watch any movie without subtitle.
I think apart from increased desire to be perceived as realistic today, in old times there was a stronger need to articulate speech clearly, because of constraints in recording and playing audio.
Then conversely, today it seems that filmmmakers often assume their series or movies are consumed on headphones or loud TVs
