Lexical tokens have types in any programming language, example: ID foo, x, n14 NUM 73, 0, 082 REAL 3.14, 10., 1e9, 0.5 COMMA , NOTEQ != LPAREN ( RPAREN ) Punctuation tokens such as IF , VOID , RETURN constructed from…

The interfaces between them are just as critical as the algorithms inside the modules. Any large software system is much easier to understand and implement if the designer takes care with the…
I had a problem where I wanted to stop leaving the terminal and going to ChatGPT back and forth just for a quick question. For example: git commands, I always forget most of git commands and I want to ask ChatGPT how can I do something using git. Also to take a suggestion for how to do something using bash (write a bash script to replace every space with a ‘_’ for all the files in that…

For the rest of the article I’m going to talk about the sunk cost fallacy.
