  • It matters as soon as a requirement change comes in and you have to change something. Writing a dirty ass incomprehensible, but working piece of code is ok, as long as no one touches it again.

    But as soon as code has to be reworked, worked on together by multiple people, or you just want to understand what you did 2 weeks earlier, code readability becomes important.

    I like Uncle Bobs Clean Code (with a grain of salt) for a general idea of what such an approach to make code readable could look like. However, it is controversial and if overdone, can achieve the opposite. I like it as a starting point though.


  • Yep, that’s what it usually boils down to. However, I think a slight approach shift for basic materials could be useful, where introductory books / papers / … write out formulas. That makes it easier to understand the basic concepts before moving onto the more complex stuff. It should be easy to create such works, as they are usually created digitally, and autocomplete is available. Students can and will abbreviate those written outs words by themselves (after all, writing is annoying), but IMO reading comprehension is the key part that can be improved.

    Also, when doing long formulas that you want to eliminate members of, writing stuff out can be a nightmare.


  • I recently held a science slam about this topic! It’s a mix of the first computer scientists being mathematicians, who love their abbreviations, and limited screen size, memory and file size. It’s a trend in computing that has been well justified in the past, but has been making it harder for people to work together. And the need to use abbreviations has completely gone with the age of auto completion and language servers.
