New blog posts and other updates

Hey folks,

A few updates and two new blog posts:

ElixirConf EU - Malaga

For those who haven't heard it yet: I will be giving a talk at ElixirConf EU in Malaga this year. It's going to be about how I ran Traceroute between 100+ datacenters on AWS, GCP, and Azure and visualised the paths that packets take between each datacenter. It's a fun one since running Elixir on so many tiny VMs is not trivial.

Monitor SSH Logins with Push Notifications

This one is a small blog post about how to notify yourself whenever someone starts an SSH session on your server. It's small but maybe useful to you.

Get instant push notifications on your phone whenever someone opens an SSH session on your server, using a simple bash script and Linux PAM.

A Devcontainer for Elixir

I wanted to make it safer to run Claude in "danger" mode to stop having to press "Yes, Yes, Yes" all the time. So, I looked into devcontainers and built one for Elixir. This container encapsulates the project and Claude and makes it somewhat safer to let Claude "run free".

Goatmire

I'm on the programme committee of Goatmire this year and we're still looking for talk proposals! You have only 3 weeks left to submit a talk, so don't dilly-dally! All kinds of talks are welcome, the crazier and more creative the better. First-time speakers are highly encouraged to submit as well; we want a colourful mix of speakers.

You can submit a talk here:

Goatmire Elixir is a small, single-track Elixir event. ...

And that's it for now! I hope you're all doing well given the state of everything.

Best, Peter
