100K is easy to break as a freelancer. You'll obviously have more things to consider - multiple clients, accounting, legal and potential downtime, but its totally doable. I think embedded could actually be a good discipline to work as

The solution to the encumbered pension fund is to transition to privately run retirement schemes like the superannuation scheme of Australia. The problem with Germany today is that the social state is archaic and has not been updated for th

It’s really incredible how YouTube shapes the zeitgeist today. Hype cycles and their “movements” should be avoided like the plague. At the end of the day if you want to gamble, buy a lottery ticket, then at least you are being honest with y

I don't think efficiency is synonymous with frontend development. Words that come to mind - technical debt, framework lock in and dependency hell. Just to name a few.

Opposite experience for me. Writing Rust on embedded systems greatly improved my confidence and speed. When using C a small mistake often leads to undefined behaviour and headaches. Rust theres none of that - its been a game changer for me.
