Blog 2: Historical Figure in Computing
Write about who you believe is the most interesting person in the history of computing. You can use someone we’ve discussed in lecture, read about in the textbook, or choose another figure that relates to what we are discussing if you’d like. You may want to do a bit of digging into this person’s history for some more ideas and information. Don’t just share what we covered in lecture, since everyone already knows most of that information. Some questions you can ask yourself:
Scratch Turing Machine
Lists in Scratch
Get an Item |
Set an Item |
Turing Machine Blocks
Turing Machine - Invert Bits
