Regular Programming

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 bee

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 de

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 poss

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 timeout

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 where does Elixir fit in?LinksMatt To

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, wa

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 larger framework with solutions and c

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

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 where you should store your traces.It i

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 cake, the coffee, and the old classma
