One thing I really like in Andreas kling's streams is just how focused his mind is while programming. Programming abstractions are the only thing consuming his brain power. He doesn't want to be anywhere else. He feels so much at peace where he is, totally submerged. You can't lure him away from staring at the monitor. He'll just reply "no thanks" to any distraction.
I don't understand anything he's doing in this video (hopefully not too long before I can), but turn to it for getting inspired by a serene programming face.
Two: how Andreas builds this JIT compiler is endlessly fascinating. It’s clearly visible that he’s spent thousands and thousands of hours of his life programming. It shows up in the large (hey, he knocks out a JIT compiler in 1.5hrs) and in the small – little tricks and moves and shortcuts. The latter is what’s so fascinating, because usually you don’t catch these small things on video, forget that you did them or don’t think they’re even worth mentioning. - Playful programming
