Needed an easy way to add RBAC (auth) to an existing k8s DigitalOcean cluster by bundling some open source tools into a simple to deploy helm repo.

We needed to have a method to deliver embedded device firmware through a secured (or not) connection, but having the datastream protected in a dynamic way, so that every device downloading the firmware will be downloading different content, decrypting it locally after the download.

Created an algorithm to encrypt the backup containing the critical files stored on an embedded device.

Created an AWK script that was used to decode a base64 string and parse the encapsulated json, checking for certain variables and settings stored in the object.

Took LinkedIn's implementation of oncall and adapted it so it supports authenticating against database stored users. Code will be pushed online eventually.

Ported the stack for Banana M3 PRO. Initially it was only working on Raspberry PI, and I only had BananaPI's. I had to use a different kernel and also adapt some build parameters. I also updated some packages that were installed by default.

While having a smallish ISP, the users were connecting through PPtP, and we needed a way of fairly sharing the outbound bandwidth between users.
There were also other methods, like using a VM and apply QoS on the traffic through it, but this was good enough at the time.

I was in need of a plugin that was small and fast and could run on a small monitoring system that I already had. So I created a minimal Perl plugin, that works with smokeping; the plugin monitors the current latency of a MySQL server.
