If you’ve been wondering how to delete a package you mistakenly installed (or which is no longer needed) along with all its dependencies, here’s a neat way to achieve just that.
The idea is that whenever you use yum to perform some operation on packages, a transaction is created. If you installed a package along with its dependencies, then you can undo just that by undoing that transaction.

If you feel like running a full bitcoin node on your Fedora Linux server (and it’s a great way to help the bitcoin network if you have spare capacity / bandwidth), you’ll need to update the firewalld rules in order to allow foreign nodes to connect to yours.

Creating an image in Docker is rather easy and well documented.
You start by editing a file which describes the image, then run a few commands, and voilà.

GoogleVoice (GV for short) is a great service (I won’t go into the details, but you can read up about it here), but it is unfortunately accessible only if you are in the USA.
Granted there is already plenty of documentation about how to circumvent this, but I’m not aware of any of those using Asterisk.
So this post will document how to sign up for a GV account as well as how to use it with Asterisk afterwards, in the prospect of using it if you are not in the USA.
In order to be able to sign up for GV, you need to meet 2 prerequisites :
- You need to have a US IP address
- You need to have a US phone number, which will be used to validate your GV account
Step 1 is left as an exercise to the reader (“Good luck ! I’m behind 7 proxies !” :D).
Step 2 is the one we’re going to describe here, as an example of what you can pull with simple Asterisk configurations.
