DaQuane Cherry was once the kid who wore a hoodie to hide skin flare-ups in school. Now he’s an artist and advocate helping others feel seen. He reflects on his psoriasis journey, the power of small joys, and why loving yourself first isn’t a cliché—it’s essential. Plus, a deep dive into the history of La Roche-Posay’s legendary spring.

Imagine Andreas going around making annoying electronic sounds all the time.

Strike that. Andreas and Lars discuss using less power - less fancy abstractions - to make things easier to understand. Andreas likes to do a de-powering pass to code.

Avoid making something which is more general than is useful.

Lars goes into the lure of event sourcing - going for very high data resolution - it might come in handy! - at the cost of a lot of other things - how do we prevent duplicate user names?

You've got to love a JSON blob.

Finally, Lars derails Andreas' arrow of time and discussion of locking things down early when possible.

How do people learn about licenses? If you entered into software in a certain way, it's easy to assume that everyone is a part-time license attorney. But how do other people pick up license knowledge? And what does one really need to know? Licenses underpin open source but seem kind of dull. But they are also a cool and special thing about the software industry. Lars provides his licenses 101 thoughts and looks forward to becoming open source grandpa.

About Learning New Languages 42:28

42:28

Everyone's favorite idempotent podcast returns to discuss learning new languages and concepts. Can mixing and matching new concepts and syntax help or hinder language adoption? A new concept but a familiar syntax might make a language easier for all the drifting Javascript developers to grab on to. Lars considers picking up a lisp at some point. It's harder to pick up new languages when you're mainly keen on building. Lars is very much in a building phase. He has problems, but they are his problems. Lars is currently learning - among other things - by working with other people, putting himself out there, and arranging a conference.

Wherein the wonders of C are explored. But first, let Andreas tell you what's so great about Chalmers' approach to teaching computer engineering. Spoiler: starting with Haskell, close to math. The tooling around C: cultural mystery meat. Lars tries out a shocking plan for a productive framework for C! It's very cool to be able to just poke memory. Memory, arrays, structs, and strings are discussed. Strings are a bundle of fun. Arrays are desugared.

37:54

What is functional programming? Andreas grabs his whiteboard and his Turing machine, and starts from laziness, while Lars thinks of immutability, functions, and data. Is syntax important for being functional or not? The functionalness of various languages are delved into, from Haskell to Rust via Python, Go, and Ruby. And, of course, the evil version of Elixir.

Lars wants a less demanding way to prepare for giving talks, but he doesn't have the time right now. Andreas knows a cheat code for public speaking. Lars uses slides like a blunt instrument. How should you wield your slides? How do you weigh information content against entertainment value? Should you try to reach precisely everyone with your talk? Many slides, or few? Lars has the questions, and some of the answers, at least for himself. Last but not least, Lars reveals his current way of preparing for talks. It ideally involves getting quite bored.

Andreas' place of work ceased to exist. It was mostly a relief. The main worry is about resting and recovering enough before whatever comes next begins. All the learnings about how not to do certain things live on. The right way of doing those things still remains to be learned. Lars is on the other end of the spectrum: beginning completely new things. Figuring out where exactly Delaware is, finding a Nerves-shaped Elixir hole, wading through Python scripts, and so much more.

Embedded is a weird thing. Lars is all Nerves and tries to explain and report from a world where people know part numbers off the top of their heads. The physical device missing is rarely a thing that happens in web development. Embedded-style work can sneak into other areas as well. Without a root file system, everything is a lot more secure. Security is a deep topic in general, and WPA is not just for wifi. Andreas shares his view of what "embedded" means, plus the story of building a really bad audio cable.

About Long-Lived Code 42:08

42:08

Fredrik wants to think about long-lived code. Lars is offended, Andreas only a little bit so. Are there other good software development practices out there? Other than the ones focusing on building something quickly? Practices for building software which lives on and is maintained for much longer than we seem to care to admit? Should we remove dependencies over time? The swamp of dependency management and vendoring is probed, gradually shifting into firmware, the horrors of floating point (proper excuses are made), small language models.

Andreas tells the story of a old system which suddenly exhibited a new and frightening bug. Lars shares similar experiences of things going wrong in new and novel ways. When things do go wrong, it is so nice to have supervision trees or other things which allow you to hear about problems, not to mention recover from them. Also covered are some stories about TCP, networks, and timeouts. And a realization that testing the frameworks upon which you build could have saved some bacon, had it just been done a long time ago.

GenServers are fun! Andreas gives all the context. Things were learned, knowledge was aquired. You can do so much with GenServers, but make sure you have a good reason. If you don't watch out, this is where concurrency goes to die. Dynamic supervisors, and their children, are thoroughly considered. Also delved into is the mess other ecosystems make of doing things at the same time, waiting, and so on. The strange worlds of C and other unusual languages are considered.

About Code Nerds 36:11

לפני 2 years36:11

36:11

The software development industry is very much built for code nerds. It shouldn’t be. Many of us know many people who are really into coding. Not every working developer can, or even should, be though. Doesn't that create kind of a weird gap between professionals who live and breathe code both on and off work, and those who have a more balanced life? Being passionate about your job shouldn't be an expectation or requirement for anyone or anything. Is there too little space for learning - are we assumed to know too much, and assumed to spend our own time figuring out things we don't?

Like data format changes, loss of messages, having 1.5 source of truths, and of course ordering. In certain cases, nobody likes an optimist.

Text editors - which ones do we enjoy, which ones have we used, and what do we actually want and need in them? Andreas has read about vim, sed and awk. Lars is quite comfortable in vim, but finds Visual studio code more than acceptable enough. Andreas is excited to show Lars how to use Vim properly. Lars considers advanced setups something of a hellscape. Lars has held a lecture about functional programming and wishes to provide a path for new .Net developers (dotnet dots?) to become free software zealots. They both share their history of editors.

How do we feel about working remotely? Pretty good, on the whole. Chairs and other basics are of course important, as is making your way of remote work a nice way of doing remote work for you. It is also nice to need to wear your work face less. The challenges are more around the social sides - communicating differently, but generally replacing and rebuilding ways of being social with people both inside and outside of your work interests. That takes work. Also, some talk about audio and video gear for remote meetings. It's nice to come off as full-fidelity people!

About Distributed Systems 36:52

36:52

Lars is thinking about distributed systems, and Andreas kind of fears them. The best thing to do for most cases might be to avoid distributing things at all. But if you do end up needing to distribute, you may run into one of the places in the world where worse is better is not necessarily better? Adding distribution on top of something not really built for it is one of the hard problems. There are deep dives into reconciliation, vector clocks, normalization, and places where fun goes to die. And there, still, are no magical solutions. Links Phoenix pubsub Worse is better ElectricSQL CRDT:s - conflict-free replicated data type The CAP theorem Soft real time Highlander N-tier architecture Postgres replication Vector clock Elixir outlaws Phoenix presence Operational transformations Split-brain Riak CouchDB Raft Paxos Normal forms for databases Googles' Mapreduce Google Spanner CockroachDB Cassandra Contentful The Cambria paper - schema evolution in distributed systems with edit lenses Quotes Distributed systems are interesting I'm doing an insert!

About Hackers Thinking about the term "hacker". Time to take it back to mean something rather down to earth, rather than a pedistal requiring years of C and a black hoodie? What do airlines have against Erlang anyway? There's also the mindset angle: the hacking mindset can be when exploring, versus when needing to solve a specific problem. The discussion goes into labels one feels comfortable with, switching between different modes, and the ever present, ever hard to find dark matter developers. Over time, labels can easily go bad in one way or another. But regardless of labels, we can all agree on duct tape and enthusiasm, right?

About Being Wrong Wherein polite gentlemen at gaming conventions explain how people didn't have their variables separate enough with regard to the Dunning-Kruger effect . Lars thinks Andreas has drawn the wrong learnings from this. It's a good idea to be humble … but strong opinions loosely held may not be the perfect thing, either? Also discussed is the curse of the expert - teaching across a large gap in experience, and how to actually go about changing systems and having better discussions. Have you considered being god's advocate instead of the devil's when in a discussion? Links Gothcon The Dunning-Kruger effect Autocorrelation The Dunning-Kruger effect is autocorrelation Golden ratio The curse of the expert The halting problem Linus Torvalds Strong opinions loosely held Steelmanning an argument Yes, and … Two's complement podcast Quotes I attempted to make friends Hard to know what you don't know If you don't have your variables separate They fumbled on the input data I think you have the wrong takeaway The curse of the expert Have you looked at presidents recently?

About Estimates Estimates are a nasty subject, Andreas doesn't know how to handle it. Fortunately, Lars has one weird trick, which doctors hate. When you have plenty of control, estimates can be useful. Not useful: unexplained deadlines. Finally: when things get stuck. (Lars is usually available to blame.) (In an alternate timeline, Andreas' tells us everything his relatives taught him about quark cake.)

Passing pandemics make it possible to meet developers in real life again. Elixir-Lars makes a splash, and tells about recent and coming real-life events he's enjoyed. Things learned from real-life events and the need - or not - of constant learning are mentioned. (It's not bit rot, it's data composting!) Finally, a deep dive into the art of arranging good events, including preparatory pre-event events. Who wouldn't like a movie night with a bunch of developers and pizza?

About Open Alternatives 1:04:18

The continued cratering of Twitter, and the joy of discovering open alternatives. Lars and many others find themselves on the open and federated Mastodon instead of Twitter, having a great time, and feeling more excited about open systems than in a long time. On the level of individuals, owning and controlling your own data feels back in fashion, but there is even more to dig into on the level of large organizations. Perhaps when GDPR says no and the good spirit of the internet is strong, there is a chance for municipalities and other public sector organizations to get and help build open alternatives to the closed, proprietary, and often hair-raisingly expensive and poorly received software they have today? Lars sees exciting business opportunities, better software for all, as well as the interesting challenges of navigating tender processes and plain old corruption.

How to teach functional programming? What are the proper steps, beyond the first ones? Especially when you can't or don't want to point to a framework and say "we do it this way!" Lars outlines his ideas for teaching Elixir to someone without requiring any prior programming experience. There is also discussion of mapping, reducing, and representing one in terms of the other. Also things which are better in Haskell than Elixir, perfectly named modules, and - inevitably - why you don't just use Rust instead. Links Chalmers CakeML Elixir in action - Saša's Elixir book Monad Map Reduce Filter MapReduce Elixir's enum module Multiple function heads in an anonymous function Immutability Guards in Elixir and Haskell Witchcraft - the module Nerves Frank Hunleth REPL Quotes It felt like I cheated, I don't know if I did In my bone marrow!

There are good things in programming, many of which are enumerated in this episode. Among other nice things: the best features in Elixir. Lars won open source? Bots and realtime-y stuff. Not to mention a type system that screams at you. Also: Lists in lists, in lists (in lists). Code made by other people is not one of the things, however. Code made by other people is always upsetting. CSS does not make the list either, but Tailwind does, prompting a discussion of fractally difficult things, leaky abstractions, and progressive enhancement.

Elon Musk wanting to buy Twitter leads naturally into the topic of cyberdecks and jacking in, which in turn naturally leads one to talk about audio on Linux. But what is a cyberdeck? How do you build one? And when would you use it? The sad state of video calls compared to Star Trek - why don't they have to install Teams to hail the Microsoft ship? Lamenting the sad state of the current crop of dystopic overlords. Who runs Google, really? Amazon might be the most attractive target, just don't take down all our clouds by accident, okay? Cyberpunk wasn't prepared for crypto, but when other things get bad enough that ceases to be a problem. Let's not papercut ourselves all the way to dystopia.
