Single-user vs service

Before you install Duplicati, there’s one question you need to ask:

Does this computer have multiple user logins (that you want to back-up), or is it primarily used by one user?

This is important because you can install Duplicati in one of two ways: to run as a single-user, or to run as a system service that is available to all users. By default Duplicati is installed for a single user, but if there is more than one user on the computer you want to be able to back-up, you’ll want to install it as a service.

If you don’t install it as a service, when Duplicati tries to read files that belong to the other users, it will get a permission denied error and won’t be able to back those files up. You don’t want to find out that your files weren’t backed up when it’s too late.

I started my voice over IP (VOIP) installation with the pre-configured for raspberry pi – “Incredible PBX” software – care of the Nerd Vittles crew.

For phones I have a Linksys RTP300 analog telephone adapter (ATA) that I purchased at a local thrift store. It’s a discontinued product, but they’re easy to find for cheap on eBay.

The one I purchased had firmware that was coded to only work with Vonage. Years ago I was able to hack it and unlock it. https://thegeekoftheworld.com/unlock-rtp300/

I replaced an 11-bay mega-tower computer, that had a 1000-watt power supply, with this:

While this setup still looks a little crazy, it’s more adapter wires than anything:

This write-up covers installation of IncrediblePBX 2020.3 on a RaspberryPi 3. The latest instructions are always available on NerdVittles and incrediblepbx.com, but I wanted to document my experience here for posterity. This article will cover installing X Windows for a GUI, and Samba & SSHFS for cross-platform file sharing on your home network.

Suddenly I find myself trapped in my own home due to COVID-19. It’s not really a big deal because I work from home normally. But it has changed my weekend plans drastically. So it’s time to start tackling one of my 2020 goals:

Organizing all of our digital files and having a consistent back-up strategy.

I was given a Raspberry Pi for my birthday last week, and I’ve already got it up and running, doing what I intended it to do: be an audio sink for iPhone and my laptop – which has terrible speakers.

I knew it would be a PulseAudio sink for my laptop. There’s also neat piece of software called shairport that will act as an AirPlay sink – and people are using it on Raspberry Pi’s.

By default, the common Linux Distribution “Raspbian” for this tiny computer uses ALSA for sound. This is fine for basic stuff, but I was reminded that when two things ever try to play sound at the same time, contention issues arise. It reminded me of a earlier day in Linux history, before the advent of PulseAudio and the magic it imparts.
