I used to do that a lot when I was younger. I didn't have my own computer until I was out of college. I would write out 6502 assembler programs by hand on graph paper and then hand-assemble the code in the columns to the left of the assembly instructions. Then I'd enter the hex code in with the Apple ][ monitor.
I used to use graph paper too. Had to transcribe everything to a teletype that only had 72 columns.
And he mentions... Java... I hope he will not be downvoted on HN because of this...
What's wrong with Java?
Everything.
That doesn't make Java developers bad in any way, though.
