VSDX = “OPC/XML drawing” – looks like my new preferred diagramming exchange format. It is at least OOXML-flavoured:

Draw.io is able to import and export diagrams as VSDX.

Update 2018-04-17:

I like the diagrams I created using draw.io.

The intention was to export them as VSDX, but in the end Visio does not display them as intended. Very, very bad!

This protects /etc/crontab against concurrent editing and corruption:

Linux package managers: permissions, user/group ownerships of files in a package
RPM based environments support verifying and resetting permissions and user/group ownerships of files in a package:
But what about Debian based ones? On Debian there is a file for every (installed) package:
- /var/lib/dpkg/info/package.list
That file only includes filenames and directory names (and no details at all). Directories are not marked as directories (as opposed to files). Files within those directories do not necessarily get listed themselves.

That file gets searched for:
- “dpkg --search” – which Debian package does a given file belong to?
- “dpkg --listfiles” – which files belong to a given Debian package?
What about the Debian utility cruft:
cruft cannot really be able to provide details not contained in that file.

Git SCM: merge local master branch with remote master branch
- https://stackoverflow.com/questions/18116198/merge-local-master-branch-with-remote-master-branch-in-git
The “git pull remote master” did not work for me, I used “git pull origin master” instead (was this right?).

Editing Jira markup in a simple browser text pane is a PITA. So I shall give this a try!
