Some more `git subtree push` quirks:

• `git subtree push` (obviously) does not push  #gitAnnex files to the remote. Syncing annexed files there is unergonomic.
• `git subtree push` also strips commit signatures (e.g. GPG and as such #OpenTimeStamps timestamps). The truth lies in the monorepo only. Understandable, but very uncool.

git submodules have neither problem, but without tools like  #datalad you can't commit at once.

#git #gitSubTree

#Haskell library and -client for working with #OpenTimestamps.

(OpenTimestamps is a protocol for creating and verifying timestamps for digital files, which can be used to prove that a file existed at a certain point in time.)

@SeaFury I can imagine! I'm in Geoscience, where things are mostly published.

But of you cite such sources as email, do you take extra precaution to preserve, archive or prove their existence? I mean an email is a pretty unreliable thing.

I think I would at least timestamp them with #OpenTimeStamps, so I could prove that this email file really existed at that time. 🤔

Hier ist die Aufzeichnung meines #TdF4 talks letzten Samstag über „Das Leben in Git (Annex)”:

Hier ist die geschnittene Aufzeichnung meines #Tübix Vortrags zum Zeitstempeln von Dateien, z.B. mit #OpenTimestamps:

#OBS hat natürlich mal wieder nur ein Standbild, aufgezeichnet aber immerhin gibts vernünftiges Audio durch das bessere Mikro.

Schneiden der #SolveSpace-Workshop-Aufzeichnung wird noch etwas dauern. Das ist komplizierter, weil mehr Dialog zum rausnehmen und weil das Mikro leider hoffnungslos übersteuert hat 😅

@joeyh Plus, considering to timestamp commits and their gpg signatures along the way with #OpenTimeStamps to keep signatures meaningful, even when a gpg key is compromised later.

https://opentimestamps.org

It basically puts a merkle tree hash of the commit into the #Bitcoin #blockchain (yes, I know...) which provides a rock-solid proof of the time the commit and signature was made (some hours precision).

This is one actually valid blockchain use case, I think.
