In case the developer sees it, on Firefox I'm not getting my key presses picked up approximately half the time when typing naturally for me. Which is probably faster than the average human but not fast for someone that is good at typing
Since even FireFox mobile did not offer reader mode to me, i used EinkBro to make it readable. Strange name but a nice alternative browser to have on Android. Got recommended here on HN.
I wrote a game in PL/M in the bad old days before good debuggers. Didn't work. Fast-forward and years later a colleague wrote a source debugger for our OS (CTOS) and in half an hour I had the game running. Bad pointer construction if I remember right - pointing to byte variables and treating them as pointers to words.
