All the good stuff seems to be happening on personal blogs/programmer's own websites and tends to be hyper-specific/technical. More general philosophy seems to be lacking and mostly the domain of writers lacking substance (the stuff on medium for instance). Unfortunately I don't really have anywhere to point you right now but if you pay attention to forums (subreddits for programming languages etc.) and the twitters of writers/programmers you stumble upon you might start to find more interesting content. There is no central place, but there are a lot of interesting people doing interesting work out there.
