Convenient DeDRM Scripts
-------------------------

**NOTE**: read https://blog.quaintous.com/2021/02/16/remove-drm-from-ebooks/ to find out what this gist is good for.

* ./init.sh:	extracts Adobe Digital Editions private key and required files to DeDRM.
* ./dedrm:	removes DRM from given ebook (pdf/epub)

If you are using this for the first time, make sure that you have authenticated your Adobe Digital Editions (ADE) and run './init.sh'. Import any DRM-protected file into ADE and run 'dedrm.sh':

ZFS Snapshots and PostgreSQL

I recently set up a host running Ubuntu 14.04 LTS, ubuntu-zfs, and PostgreSQL 9.3. Using the ZFS snapshot feature I was able to make a snapshot of the file system holding the PostgreSQL database, write the snapshot to a compressed file, transfer it to another Ubuntu 14.04 LTS host running ubuntu-zfs, restore it, and launch PostgreSQL using that data directory with all the data (seemingly) intact.

The database is very low-traffic, so I do not know how effective this strategy would be for a busier database.

I take no responsibility if you attempt this setup and it causes data loss or other issues. Use it at your own risk; this document is meant to explain a potential setup and open discussion about limitations and potential improvements.

First Host Setup

 * You'll need three keys in order to unlock the
 * Algorithm: the red key, the green key, and the
 * blue key. Unfortunately, all three of them are
 * behind human-proof barriers.
 *
 * The plan is simple: reprogram the maintenance
 * robots to grab the key and bring it through

 * Oh. Oh, I see. This wasn't quite part of the plan.

 * Looks like they won't let you take the Algorithm
 * without a fight. You'll need to carefully weave your
 * way through the guard drones.

 * Changing your environment is no longer enough. You must
 * learn to change yourself. I've sent you a little something
 * that should help with that.
