Is there an open—source Swift IDE that can modify itself without restarting? (written in Swift) I loved Oberon µSystems Oberon/F aka Component Pascal for that capability.
Back in the early ‘70s, I worked at a computer network that had remote clients up and doen the Eastern seabboard, from Maine to D.C. They used a circular buffer for output from client submitted jobs. One day the buffer lapped itself. Panic ensued.
If you pay attention to the cursor, instead of aiming at the corner of the window, the UI gives you great feedback of where you should click: when the cursor changes to 2 arrowheads pointing diagonally or orthagonally to the window, resizing is available. Why aim for inside the window? I do think the expanded corner radius of Tahoe sucks badly.
