The big wigs want PDFs. and Lots of them. Unfortunately, lots of the good info is behind authentication. How can we render a PDF of a page behind Auth?
What’s the fix? About 10 lines of Elixir!

Elixir Streams |> 🤔 and/or Vs. &&/||. Which to use?
Someone recently asked me which to use: and/or OR &&/||?
Decided to make a short video about it.
Though they’re similar in many ways, they’re not the same! Here are some useful differences and some pitfalls. 👇

The next Nerves embedded systems meetup is Wednesday, April 24th! This will be a social gathering to hang out with other Elixir/embedded engineers, share projects, ask questions, and get help! RSVP here:
Elixir + Phoenix: How to Raise Custom HTTP Error Responses in Your REST API
This blog post shows how, by adding a few lines of code, you can return a custom HTTP error response (with status code and custom message/payload) in your Elixir + Phoenix REST API, at any time in the request-response lifecycle.

Phoenix admin frameworks - a very subjective evaluation
I needed to add a small admin interface to a webapp I’m making. See how I got there, and why I decided on using Kaffy in the end.

Elixir development using Podman with VM in Parallels and Shared Folders
We’ve recently started to use containers instead of asdf on Mac for development again, and the setup I’m using is based on podman. We’ve chosen podman because from our perspective it’s easier to use in production when compared to docker, and we wanted to be closer to the production environment on our development machines as well. Since setting this up using Parallels instead of the default QEMU VM’s was rather involved, we’ve summarized all the necessary steps in a blog post for anyone else who’d like to check this setup out.

Interviewing Tips!
My fellow Elixir-devs (I’ve never grown too fond of “Alchemists”), I know this isn’t the most Elixir of all posts but I’ve seen many people make simple mistakes during hiring processes. And I want to help fix that, so I’ve written a series of posts geared towards programmers about interviewing that I hope y’all will find helpful!
Easy at-home AI with Bumblebee and Fly GPUs
A big barrier to getting started with local AI development is access to hardware. And by “local”, I mean having direct access to a GPU and not going through AI-as-a-Service. Some of us are lucky enough to have a beefy Nvidia GPU, if so, good for you. For the rest of us, we can use a GPU on Fly.io while editing the app on our machine. Sounds crazy? It’s actually really cool, and easy. Check out the ready-to-deploy server app with 3 LLMs setup for your immediate enjoyment.
