Notes for powerusers[edit]

Wikipedia is great for simple editing, but once you want to do some more complicated work, the tools are often hidden. Here are some tools I've found:

Programming philosophies[edit]

Things that smart people have said (or the young trade of programming has produced), that might be worth considering


  • Goto statement considered harmful

Free up images in Comparison of rapid transit systems[edit]

Apparently some of these logos are copyrighted, I'm working on fixing that. See Talk:Comparison of rapid transit systems

Cleanup hatnotes[edit]

There are a lot of hatnotes with numbered names, like {{otheruses4}}, that are cryptic and unnecessarily complicated for newcomers. They ought to be cleaned.

What's been done:

  • {{otheruses4}} -> {{about}}
  • Work on documentation and Wikipedia style suggestions and help pages to suggest the use of {{about}}, {{otheruses}} and {{for}}.
  • Get rid of redundant templates from documentation (e.g. {{otheruses1}} and {{otheruses3}} -- which can be replaced directly by {{about}} and {{otheruses}})
  • Suggest redirect for these
