I got some troublesome filament and ... What's this? Am I over extruding? I'm not really seeing that on the sides. Most of what I get is fine but this bottom is trashed and I have no idea why.

I got asked by a non technical friend

>Technical question: What does signal do which is more secure than WhatsApp or Facebook messenger which both have end to end encryption.

and I basically talked about the companies and the closed source vs open source app. I feel like there should be a blog post I can point them to however. Any points I missed?
