Regular Programming Lars Wikman, Andreas Ekeroot

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.

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 recruitment, both as part of interviews and as a more straightforward recruiter.
Finally: the secret to everything Lars does.

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 plain SQL-land.
Some people have just been bitten so hard by cowboys.

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.
Finally, of course, indecent cups of tea.

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 Linux audio, and musings about the possibility of creating really nice audio tools for the platform.

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.
