Who are we?
Dr. Chris Zimmermann is a FOSS fanatic, communist (sometimes) and expert on esoteric software aspects how to configure Mail Transfer Agents while not carving in to insanity, troubleshoot computer networks without the use of recreational drugs and the advanced enjoyment of craft beverages. He mostly lives in Frankfurt, Germany. In contrast to Mr. Visser the size of his brain has a reverse correlation to the size of his head.
Martin Visser is a slightly less egocentric (actually far from egocentric) computer scientist and engineer, non-communist from Birmingham, UK. In contrast to Dr. Zimmermann, he has human interaction and social protocols down to a fine art.
Why another FOSS podcast?
For those who use any means of transport on a regular basis it is a great way to stimulate the brain.
Others have come before us, tried and failed to achieve this level.
What's in it for me?
Invaluable tech tips helping with aspects of everday life including the proper recital of Vogon poetry in that worst-case scenario that Brexit finally shadows the Vogons’ landing and how to take care of the proper biological foundation for recreational drugs
A chance to feedback your comments. Glowing ones will be published, others ignored.
The opportunity to request expert knowledge and discussion on a topic of your choice!
What's in it for the Inlaws?
The impending fame and successful broadcasting careers (Martin’s vision) play a small part in this decision.
Which is of course totally overshadowed by the reason of world domination. Donations are encouraged. Ideally in liquid wheat brew format (of course rye, barley, spelt and other assorted grains go as well).
How to get up and running?
(this is how we do it, your mileage may vary)
- Pick an open source operating system of choice that features a decent package management system (unless you’re really technical and know what you’re doing) and is Posix-compliant. In this instance Ubuntu 19.10 was the preferred candidate
- Don't worry about Mumble. Many have tried, most have failed to use this piece of
software for synchronous podcast recording
- Get some really cool music licensed under CC-BY(-SA) from places like Jamendo
- Install a Synapse server on a publicly accessible server and use Riot-Web as a front-end for this instance
- Get Audacity and tty-clock (if you really want to accurate synchronise your system clock with an NTP server)
- Using Audacity and tty-clock, record your friendly podcast locally using Riot-Web's audio call feature to synchronise the hosts and guests
- For the post-production, simply mix the individual streams together and edit to your
- Stick to mono when producing the final ogg or mp3 file, adding music and other content as appropriate
- Upload the audio file to HPR
- Create associated website using some cool HTML/CSS framework
- Watch it go viral (the important bit!)
- One home server running Ubuntu 19.10 with mumble-server and Synapse (a reference implementation) of the federated protocol known as Matrix for comms
- One cheap bit of kit running somewhere in Germany at a snails pace (Martin’s opinion before the D-Wave upgrade - little did he know :-)) => much patience is required attempting to use this
- Two laptops for remote access, running a Murmur client (typically Mumble itself), Audacity and various text editors in addition to riot-web or another Matrix / Synapse client
- One MPow USB headset and one interim Logitech 2 Pro (thank you MPow for the countless hours of debugging x-talk issues - we learned a lot! :-)
All episodes are hosted
on Hacker Public Radio
The following only represents the last ten episodes, you find the
full backcatalog of all episodes release so far here.
- S01E31: Interview with Paul Ramsey FOSS afficionado and enterpreneur
In this episode the inlaws host Paul Ramsey of OpenGeo fame. Apart from his PostgreSQL contributions,
Paul is probaby best known for GIS work and geo DB contributions in general (in addition to
off-the-beaten track stuff like URL of his website among other things). Don't miss this for nuggets
on geo databases and beyond!
- S01E30: Politicians and artificial intelligence part 2
After successfully navigating through the shallow (or not-so-shallow) depths of the first episode on
deep learning fundamentals, our two heroes tackle a more concrete topic in this episode: How to use the
damn stuff! No expenses will be spared to bring to the listeners the finer details of tensors, TensorFlow
and other frameworks which serve as the basis for modern artificial intelligence / machine learning
applications running on back-propagation networks (see the first episode on the foundations). Lifting the
curtain even more, all will be revealed about a little corner shop called "Google" (well, almost all :-).
- S01E29: The (one and only) Linux Kernel Contributor Panel
In this episode, our two ageing heroes host an eclectic panel of kernel contributors of a small, mostly
unknown operating system called "Linux". The panelists hail from all over the planet (sadly, no money
or love would buy Richard's or Linus' way onto that panel :-) but the discussion proves more than interesting
regardless of these uber-nerds being absent. All will be revealed including the true age of Linux,
one of Chris' secret obsessions (hint: it's not software bugs), Linus Torvald's thought
process and evolution as such. Never mind Linux's second future high-level programming language...
Plus: a philosophical discussion of the social impact of insulting from a pan-cultural perspective.
Don't miss out on this!
- S01E28: Politicians and artificial intelligence part 1
In this episode, our two heroes explore the realm of artificial intelligence, paying special attention
to deep learning (hoping that some of the stuff may rub on them :-). In this first part of a three-part mini-series
the chaps discuss the foundation including networks, neurons and other topics of advanced black magic, carefully
avoiding the tempations of introducing too much maths (we'll leave this to the Grumpy Old Coders :-).
- S01E27: The Big Uncertainties in Life and beyond
In this episode, our two heroes explore the realm of the great uncertainties also known
as probabilistic data structures. For this adventure they managed to retain one of the
experts in this field from the open source realm. Check out the episode to get in on this
secret and its details!
- S01E26: Make your Linux Harder
In this episode our two aging heroes discuss the proper temperatur to drink beer at (spoiler: it's not 20 degrees as
CAMRA would make you believe) and the ins and outs of basic and enhanced security on our beloved operating system.
If you ever wanted to know more about Linux Security Modules, AppArmor and SELinux and how dames of negiotiable
affections relate to these concepts, this show is for you.
- S01E25: The Grumpy Old Coders
This time our two heroes host an eclectic couple known as the grumpy old coders. Thomas, David, Martin and Chris
discuss stealing, um, borrowing (and never giving back) of mottos and mascotts, programming languages including
Java, Python and Rust woes and how they all arrived at podcasting. Never mind Chris revealing his true and
only heritage and other little-known secrets. Don't miss out on this episode for the full lowdown (never mind
the even lower down :-).
- S01E24: Legacy Programming Languages
In this episode our two heroes discuss programming language that are actually older than themselves (and, no, not
combined) and - blatant teaser - come the conclusion that... What the heck, listen to the episode! :-) And don't mind
Martin almost falling asleep during the second half of the episode...
- S01E23: The first year of the five year plan
In this episode, our two commrades discuss the first years of the five year plan of the road world domination
through something called Open Source Software using Linux Inlaws as their weapon of choice. Don't miss out
on what has been, still is, and - equally important - will be! Never mind that this is a world record for the
Inlaws: An episode where the outtakes may actually be longer than the show itself!! Plus *the* tidbit where Martin
reveals it all: his history never mind the few things he still has to learn about the free software revolution.
- S01E22: The Linux Professional Institute
In this episode our two elderly heroes - somewhat challenged by Finagle's and Murphy's laws and
evil audio deities - interview Evan Leibovitch of the Linux Professional Institute. For a change,
Martin takes a lead in this episode and Chris remains in the background only asking the occasional
question (for a refreshing change). [Martin owes Chris a fiver due to a lost bet
as this episode indeed proves that he can shut up for a change :-]

The DarkSide Tech Support (DSTS)
The DSTS is loosely inspired by the Bastard Operator From Hell,
where a somewhat misguided support specialist tends to break all hell loose on innocent callers who expect help
and guidance on various computer problems. In contrast to this purely fictional prototype, the DSTS deals with
real-world problems such as rewriting history aided by computers, how American presidents tackle virus issues and
how an ancient Egyptian pharaoh tries to remedy the seven plagues inflicted on his empire by talking to God herself.
More episodes in the making - stay tuned!
Similar to other parts of the show, DSTS welcomes listeners' suggestion about topics they would like
to see covered. So if you have a plague you cannot get rid of or need divine intervention otherwise, don't
hesitate to send us a mail.
