I once wrote this language aware diff tool in JavaScript that supported about 40 languages. I had not used it in years so I stopped maintaining it and moved onto other hobbies, but this year I have found it’s helped on various different things.
My current hobby JavaScript application does file system search faster than the tools provided by most operating systems and allows search using regex or negative string tokens. That’s sometimes helpful.
A blank page. It's the beginning of a new task. It shouldn't distract me from accomplishing it.
