Ask HN: Programs that saved you 100 hours? (2022 edition)
Gotta say IntelliJ, which isn't just for Java.  It's a great coding platform and I used it for Scala, Go, Python, Bash, Java, PHP, Perl, you name it.  I know many people like to hate on IDEs, but IntelliJ (and/or its language-specific variants like PyCharm or GoLand) has great support for all the debuggers in the above languages.  It has awesome search/replace.  Being able to "drill down" in to code, including 3rd party libraries with barely any configuration is like magic.  The git integration is phenomenal - I rarely get stumped doing anything in git and dealing with merge conflicts are a breeze.
