Turn your Linux box into a Bluetooth audio endpoint (quick guide)

This short article shows a simple PipeWire + BlueZ setup to let a Linux machine act as a Bluetooth audio endpoint — for example, to play audio from your phone to a USB headset attached to the Linux box. The commands below are the minimal steps: install the packages, enable services, verify PipeWire is running, pair/connect from the phone, and optionally select the USB headset as the default sink.

Tested environment

The steps in this guide were validated on the following setup:

Sync (migrate) a Dovecot Email Account from One Dovecot Server to Another

The man doveadm-sync pages are cryptic and not very well explained, as well they are missing quality real-world examples.

This gist aims to give some clarity and explanation.

Here is the command I got to successfully transfer (and sync backwards too) an email account from an old Dovecot email server to a new Dovecot email server:

To my knowledge, both servers must have a matching account already setup for this to work:

Project Architecture For Front End Applications

Deciding how to design your project's architecture is still a complex thing. Everybody while starting a project goes through different articles and blogs to understand the ways to develop your project's architecture.


Working on a badly designed project's architecture is as difficult as designing it good.

The Architecture of your project should be so neat and descriptive such that if a new developer starts working on it, one should not encounter any problem in understanding the patht that the data follows to render the ui.

	Work for me with squid 3.4 on debian jessie.

	I use it with collectd exec plugin (https://collectd.org/documentation/manpages/collectd-exec.5.shtml)
	to collect data from squid, send it over the network to influxdb and visualize with grafana.

	Maybe someone will have some use of it. Good luck ;-)

	Two things are wrong with Django's default `SECRET_KEY` system:

	1. It is not random but pseudo-random
	2. It saves and displays the SECRET_KEY in `settings.py`

	This snippet
	1. uses `SystemRandom()` instead to generate a random key
	2. saves a local `secret.txt`
