Today I Learned: 1) We've had jellyfish in space since 1991. A bag full of polyps was sent to up with a space shuttle, and has been growing in microgravity ever since. The jellyfish were recently brought back to Earth. They did not handle gravity very well -- they were pretty bad at maintaining orientation in true gravity. 2) Spaghetti is... trickier to cook in tomato sauce than the other pastas I've tried. Sauce doesn't soak into the pasta as quickly as boiling water, which means there's this awkward and rather lengthy period where the spaghetti remains stiff, which makes it a) hard to mix in properly to where it can absorb sauce better and b) hard to mix the bottom, which causes it to tend to burn. 3) Never run "conda upgrade --all" without superuser privilages. Just like with pip, if conda detects that it needs to upgrade itself, it will download the newer version of itself, uninstall itslef, and re-install the new version. Except that if you don't have superuser priviliges, it fails during the reinstallation bit, leaving you with a broken, half-uninstalled conda that's really difficult to clean up after.
