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.

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.

Finally, a dive into the wonderful world of interoperability, both with and without C directly involved.

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.

A good pipeline can be really nice.

Oh, and you shouldn't use witchcraft anymore.

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.

What are people talking about when they talk about developer experience? Pretty colors in the terminal?

What is worth improving, what is not? Lars has thoughts about all of developer experience, not least the one of Nerves. How flaky do you accept, for how fast?

Revealed: why all Andreas' Elm programs are one line long.

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.

CRUD - a classic term among supposedly simple web apps. But, not always the right move? Not always all that mappable to the actual problem?

Discussed: picking spicy architectures, non-CRUD data storage needs, slovely solutions, dirty refunds, and doing the OAuth dance.

Hey, thing happened!

Finally: a story where pubsub was reasonable, and some telemetry.
