Today’s article explains how to simulate a bad internet connection when developing locally by adding latency, jitter, and package loss to your connection. It’s crucial to test your app under these circumstances before deploying it. Otherwise, especially users on a mobile connection will have a bad UX when using your site.

Securing Elixir/Phoenix Applications: 5 Tips to Get Started
Hey everyone, this article consists of five recommendations:
- Read the EEF’s Secure Coding and Deployment Hardening Guidelines
- Use Sobelow for static analysis
- Check for vulnerable dependencies with MixAudit
- Harden your application against bot attacks (I don’t recommend reCaptcha)
- Use the SafeURL library to stop SSRF attacks
Hope it’s useful in your work!

Learn how to build a Roles and Permissions (RAP) system for Phoenix! Not all your users should have access to all your data. A RAP helps you to set up user groups and control which data they can access through permissions.

Thanks for the post, Peter!
It was very timely for me, as I’ve been working on an authorization library over the last few days and took this as an opportunity to integrate it with your RAP example. I wrote up some thoughts and added the modified modules in a gist. It was a great opportunity to see how the auth library I’m working on might integrate with the permissions architecture you presented. Would love to hear your (or anyone else’s) feedback, if you find time to take a look.
Looking forward to part 2!

This is so cool!!! Amazing work! 
Do you have a thread here where we could discuss this? I have a few thoughts

This post covers how a CSRF attack works, and the defaults Phoenix gives you to discourage writing vulnerable code.

I wrote a small walkthrough of the new Neural Network smart cell in Livebook 0.8. It’s simply amazing that you can run these models locally in Elixir now!
