Restore intentionally deleted commits in Git

Restore intentionally deleted commits in Git (remote)

Situation

  1. You own a Git repository server and the developers do not have access to it (i.e. they can only read & write to the repo, but not gc it).
  2. You had a developer that wrote a project for you.
  3. He got angry for whatever reason and deleted all branches from the remote repo. He also push -fed the master branch leaving only one silly commit there.
  4. He escaped from the country leaving you without any code at all (at least this is what he believe in).
  5. You have never cloned the repo to other machine. There were only two copies of it: the developer's one and the server's one.

SUPLA Events by @fracz

SUPLA Events (unofficial)

This is a SUPLA Cloud extension that enables basic events support. Installation includes changing some sources of SUPLA Cloud instance (yes, you need to have your own SUPLA Cloud, it cannot use it on a shared official platform at supla.org).

Event specification consist of a condition (what should happen in order for the event to be perceived as occured) and a webhooks, that is, URLs to call in such cases. The condition is a Twig expression with a simple state function provided. state(XX) returns a state of a channel with ID XX. The returned value depends on the channel function. You will find the example states for specific functions helpful. Take a look at example config.yml for different possibilities.

Event specification might also contain a time_conditions, that is cron expression (or array of them) specifying when the event should be active. If the time conditio
