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 - …

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 soft…

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…

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. …

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 versi…

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? …

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. Also: Why not attend the Øre…

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 thi…

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 tele…

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. Secu…

Andreas is a man of many hobbies. Interviewing for example. But sometimes, you get strange questions from strange people, end up feeling scared, or start lying just a bit. Then, perhaps, you tell the story of a bug. Perhaps we shouldn't work during the winter? Lars doesn't have interviews. More like sales calls. H§e shares his experiences of how to…

Stories about Ecto quickly redeeming itself, and of what it takes to introduce foreign keys. Some of us are super comfortable referencing the ID. Lars dislikes that Ecto needs to be more complicated because of SQL, but the abstractions do hold. Also: the biggest reason to ever use a ORM! It can be reallynice to come back to one after a tour of plai…

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 depe…

The Saint Valentine's peak passed without issue. Andreas had time for semlor. Lars has opinions on semlor, and can imagine many possible improvements. Like having an apple. Or a pizza. Lars has had a nice influx of work, including hardware work using Nerves. Testing and very hackish hot code reloading are both included. Finally, some thoughts on Li…

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 stor…

Lars dove into data pipelines, and emerged bearing arrows and wishing for a lot fewer copies. What is there to think about regarding data pipelines, what is interesting about them? Which tools are out there, and why might you want to use them? Why all this talk about making fewer copies of data? What does Lars' current ideal pipeline look like, and…

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…

Every web app starts out fine, the tabula rasa of an unwritten BODY. But sooner or later you need users. And a million other things which live in trees. Also: email. And that layer between the controller and the database where things like fine-grained access control goes. I'd like to have an admin, please. Eventually, web apps grows up. And while a…

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 lif…

Data has moved to a real database. Next, there may be brave attempts to add actual structure. Working with a real database is nice, as is not losing data, and being able to restore. Not everything is ephemeral, after all. Database service providers and cool stuff they do are discussed. The deal with Elastic is clarified. Finally, it is revealed whe…

It seems a mingle is a thing, and not just in Swedish! But what do we want to get out of them, how do we go into them, and how do we create good ones? Do you want resonance or hole-poking when you tell people about your plan to arm toddlers with nuclear weapons? Do you want to successfully mingle nerds, or just hit the snacks hard? The foood, the c…

Performance: we wish the incentives were there to focus on it more often. Lars would like more opportunities and incentives to focus on making things fast, rather than just making them not slow. Unfortunately, things tend to line up so that fast enough and more features are in focus. Plus, performance and optimization can be very context sensitive …

CTOs want the ability to get prototypes built and out into production fast. Others preach the gospel of building things properly. How fast can you be? How much can you perpare before you hit the ice? And one you built and shipped that prototype, how can you get any kind of speed trying to maintain and evolve something where many corners were cut fo…

Did they do design, or did they just do a system? Distributed systems are hard in many ways. Andreas describes a system communicating between backends and mobile phones in exciting ways with many exciting possibilities for errors. Like data format changes, loss of messages, having 1.5 source of truths, and of course ordering. In certain cases, nobo…

Lars went to ElixirConf EU. Going to a conference can be a credibly incredible experience. Elixir has more clarity than Erlang. Lars also gave a talk, a fact he was comfortably uncomfortable with. Giving a talk also comes with benefits such as being able to talk to fish in a barrel. But why did he choose to make the whole talk a demo? What is the g…

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 hel…

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…

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 …

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 disc…

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 i…

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 …

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 arrangi…

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, b…

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…

Archives are cool. How do you keep your digital things in order and, hopefully, backed up? We need more archivists. Andreas has re-read Snowcrash, and while it isn't the manual for the world to adopt it doesn't seem to stop the megacorps from thinking it is and trying. Where did Google go wrong, and why? And why aren't we jealous of their recruitin…

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…

The hardware woes episode. But first: the joy and wonder of ID3v2.3. Implementing the specification of a binary format as a library. Lars' next laptop. Then Lars' gear situation. Power bricks and cable capabilities are … a labyrinth. The trials and tribulations of getting and setting up a Steam deck. Linkable matter * The ID3v2.3 spec * EXIF * Fold…

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? …
