@blinry@chaos.social ruby's irb and python have the same feature with the _ variable! IRB: irb(main):001> 5 + 2 => 7 irb(main):002> _ => 7 Python also seems to avoid overriding _ when your statement returns None: >>> 5 + 2 7 >>> _ 7 >>> print("hello world") hello world >>> _ # still 7! 7 >>> None >>> _ # still 7! 7

@amartya@fosstodon.org Looking forward to more from your blog! Judging by the URL it seems to be just a HTML file, but if you ever decide to make posting more automated, please consider providing an RSS/Atom feed.

@blinry@chaos.social Due to sheer practicality, I'd give up an entire month's salary before I give up on the Network tab. If I was a better person, I'd know something about the accessibility tab. If my work let me prioritize the way I wanted I would spend all my time on the performance tab. The Firefox profiler and their flame graph is so good, that there's a ruby gem called Vernier (also very good!) whose profile viewer is forked from Firefox: https://vernier.prof/

@jer@hachyderm.io @blinry@chaos.social That's a really good one! One liners are well and good, but the real tip is using $_ when golfing to avoid the chars of saving the output of gets to a variable 😆

There are also a bunch of similar global variables for anyone wanting to go down a rabbit hole, especially relating to regex in ruby: https://ruby-doc.org/docs/ruby-doc-bundle/UsersGuide/rg/globalvars.html
