Regex Pattern to Match, Excluding when… / Except between
...r example, as well as the still-experimental regex module to replace re in Python, are the only two engines I know that support infinite-width lookbehind. With these tools, one condition in one lookbehind can take care of looking not only behind but also at the match and beyond the match, avoiding t...

Firmware offers OS-like functionality on which most OS-es depend. E.g. a Python subset has been ported to run on BIOS / UEFI: https://www.youtube.com/watch?v=bYQ_lq5dcvM
It can be argued that firmwares are indistinguishable from OSes, and that firmware is the only "true" bare metal programming one...
What are the barriers to understanding pointers and what can be done to overcome them? [closed]
...ement a simple bytecode based virtual machine (in any language they chose, python works great for this) with an instruction set focussed on pointer operations (load, store, direct/indirect addressing). Then ask them to write simple programs for that instruction set.

Dynamic type languages versus static type languages
...ly, dynamic typing has caught on in the contexts of education (e.g. Scheme/Python at MIT) and domain-specific languages for non-programmers (e.g. Mathematica). Dynamic languages have also caught on in niches where they have little or no competition (e.g. Javascript).

I apologize for this code written in Python, but regexes are trans-langage and I think everybody will be capable of undertsanding the reex's pattern
