Linux Inlaws

This episode as part of our strange but wonderful series is host to one of the most elusive musicians not only in the podcast biz. Yes, we are speaking about none other than the mysterious Breakmaster Cylinder, also affectionately known as BmC. Who you may ask? If you have strayed and listened to other podcasts (shame on you BTW :-) like Darknet Diaries or the Changelog, you've already experienced some of his work. Sparing no expenses, Martin and Chris managed to get him on the show. Suffice it say, this is one of the most complex but still comprehensible shows (spoiler: BmC turns the tables has questions for our two hosts - what a ride it was). So without further ado, fasten your seatbelts, stop smoking (it's bad for you anyway) and enjoy the show!

This episode - aptly named "Missing link" and part of our foundations series of our highly valued educational sub-Inlaws (a marketing term blatantly borrowed from Reddit when it was still relevant but conveniently always forgotten to give back) - dives deep into the innards of computer systems, networks and distributed applications. Discussing the communication mechanism these components use to be precisely to wrack havoc on innocent users, clients, servers and other shenanigans naively using these. So you've missed that all-important third-year operating and/or distributed systems class back in university, now's the chance to catch up on things. So that the next cocktail conversation doesn't have to be about the shortcomings of certain US presidents, open marriages, the weather and other strange phenomena including vampires turned priests in order to gain the upper hand on vegan blood wholesale empires (blatant teaser for an upcoming DSTS episode perhaps? :-).

This show is host to two clouds, Nextcloud and OpenCloud. A little bit of history: Both clouds go back to some common origin called ownCloud, a FLOSS project devised around sixteen years ago with the aim to allow each and every user of the software to have their own file hosting and synchronisation platform. ownCloud was forked to become NextCloud around 2016 and OpenCloud came into existence in 2025 when ownCloud was forked once again. Curious? Then don't wait but rather hit play to listen to the episode. As we hear this straight from the horse's mouth. As we the founders of both companies on the show speaking about the origins, present state and future. Even if you're not into file synchronisation you don't want to miss this episode as there's both projects have evolved over the years time to become much much more than pure file-hosting platforms (yea, we are talking office functionality similar to the proprietary functionality available from your big hyperscalers, etc.). Interested? Then don't miss this episode.

In this episode Martin and Chris tackle the important subject of digital sovereignty. Something becoming more and more important if you don't want to wake up one morning just to see all of your mails and mailboxes vanished just because some foreign provider decided to cut off your mail server access (same goes for file cloud storage, office software, etc. Many other use cases do apply). But how to tackle this conundrum? Fear not, dear listeners, as usual the inlaws got you covered. So don't miss this episode!

This episode is host to an eclectic panel representing a German project called Freifunk, essentially a free-for-all mesh network providing Internet access to the general public. Originally developed as a local shortcut to a fast Internet hookup in Berlin, this project has become hugely successful in metropolitan areas around Germany and beyond. So if you have ever wondered about these access points with the name freifunk as part of the name, are just plain curious about the technology behind this network or even thought about running an access point yourself, you don't want to miss this show!
