Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

Installer equivs
Créer un sous-répertoire : mkdir my-meta-package et cd my-meta-package
Créer un template : equivs-control ns-control
Modifier le fichier ns-control selon les besoins
Construire un .deb et .dsc : equivs-build --full ns-control
Construire un paquet source : dpkg-source -x my-meta-package_<version>.dsc
Créer le fichier source.changes : cd my-meta-package- et debuild -S

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

	# This gist contains pre-commit hooks to prevent you from commiting bad code or to the wrong branch.
	# There are four variants that I have built:
	# - pre-commit: stops commits to "master" and "develop" branches.
	# - pre-commit-2: also includes a core.whitespace check.
	# - pre-commit-3: the core.whitespace check and an EOF-newline-check.
	# - pre-commit-4: only the core.whitespace check.
	# Set desired version like this before installing:
	# FILE=pre-commit
