Problem

You have installed GPG, then tried to commit and suddenly you see this error message after it:

error: gpg failed to sign the data
fatal: failed to write commit object

Debug

Let machine M be the Main machine with the repo, and A the Auxiliary machine which wants to help out.

First time setup

Machine M creates bundle with complete repo:

git bundle create repo.bundle HEAD master

M sends repo.bundle to A.
A clones repo from bundle:

My useful utilities and favourite programs to make everyday life that bit easier

Most of these are Windows based, but some are cross-platform. They are mainly free tools, but paid ones have been marked accordingly. Freemium tools have a free version but have a full version for a price. Tools are in no particular order

From: http://stackoverflow.com/questions/1676632/whats-a-quick-way-to-comment-uncomment-lines-in-vim

For those tasks I use most of the time block selection.

Put your cursor on the first # character, press Ctrl``V (or Ctrl``Q for gVim), and go down until the last commented line and press x, that will delete all the # characters vertically.

For commenting a block of text is almost the same: First, go to the first line you want to comment, press Ctrl``V, and select until the last line. Second, press Shift``I``#``Esc (then give it a second), and it will insert a # character on all selected lines. For the stripped-down version of vim shipped with debian/ubuntu by default, type : s/^/# in the second step instead.

NOTE: This is a question I found on StackOverflow which I’ve archived here, because the answer is so effing phenomenal.

Q: How can I make a chain of function decorators in Python?

If you are not into long explanations, see [Paolo Bergantino’s answer][2].
