Pushing to Multiple Git Repos

If a project has to have multiple git repos (e.g. Bitbucket and Github) then it's better that they remain in sync.

Usually this would involve pushing each branch to each repo in turn, but actually Git allows pushing to multiple repos in one go.

If in doubt about what git is doing when you run these commands, just

How to add syntax-highlighted code to PowerPoint slides (Mac OS)

1. pygmentize -f rtf FILE | pbcopy
2. Paste into TextEdit (in rich text mode: Format → Make Rich Text before pasting), and copy to clipboard again.
3. In PowerPoint, Edit → Paste Special… → Styled Text.

(Pasting RTF directly into PowerPoint doesn't work correctly, at least with PowerPoint 2008 — it extends colour spans longer than it should, and sometimes removes line breaks. Going via TextEdit seems to solve the problem.)
