To be honest, that in itself is probably worthy of notice. It is not a self-evident truth that all the laws of physics work exactly the same throughout the entire universe. There have, for example, been quite a few theories that have postulated that some of the fundamental constants may vary over space and/or time.

Therefore, just the confirmation that chemistry actually does seem work the same 11 billion years ago on the other side of the known universe is certainly not worthless knowledge. It may also have provided some knowledge about how long it takes for oxygen to accumulate in the evolution of a galaxy (though that may well have been known previously).

Furthermore, of course, it is a great verification of our observational capacity. Though the existence of water may not have been unexpected, our ability to observe it is quite something to marvel at, if I may say so.

Not that you don't have a point at all, but your argument is quite akin to saying that all games are equivalent -- "If you think The Sims is overpriced, just buy Unreal Tournament instead". Which is, needless to say, also quite ludicrous.

And you needed this article to tell you that something was wrong? ;)

Minor correction: That seems to be gtk-can-change-accels = 1. At least my GTK did not accept true as a valid value.

In that case, your editor is doing something hideously wrong. Python's parser follows the traditional rule that a tab forwards to the next column divisible by 8, which is how all reasonable programs interpret Tab characters.

Many programs that have functionality for writing Python code avoid the use of tabs completely, though. Emacs being one of them.

Yes, and don't forget C-x z for repeating a command such as C-x e. The convenient thing about it is that you can keep pressing just the z key afterwards to keep repeating.

I find it especially useful when re-indenting code blocks that are a bit to irregular to use C-c C-q: Just do C-x ( TAB C-n C-x ) C-x e C-x z z z z...
