Grab ffmpeg from https://www.ffmpeg.org/download.html

It's a command line tool which means you will have to type things with your keyboard instead of clicking on buttons.

The most trivial operation would be converting gifs:

ffmpeg -i your_gif.gif -c:v libvpx -crf 12 -b:v 500K output.webm

-crf values can go from 4 to 63. Lower values mean better quality.
-b:v is the maximum allowed bitrate. Higher means better quality.

superfish.pem contains:

the Superfish certificate as found by both Chris Palmer and Matt Burke;
the encrypted private key as found by Karl Koscher.

$ openssl x509 -in superfish.pem -text

How Do I Into Git?

a helpful primer for users sick of git's poorly-named commands

I've used Git since 2011, and this is the stuff that I've always had to Google to remember. I hope it helps you not hate Git so much.

I'm getting adverts in my TV's UI, help!

Samsung's otherwise excellent 2016 range of UHD TVs received an update that added advertisements to the UI. This has been complained about at great length on Samsung's forums and repeatedly, Samsung have refused to add an option to remove them.

The ads interrupt the clean UI of the TV and are invasive. Here's an example of how they look:

This guide was originally posted on Samsung's TV forums but unfortunately, that site is a super-slow and barely accessible unusable mess.

Ubiquiti USG Advanced Configuration

Overview

Integrated DNS Overview

When using a USG with Ubiquiti's Unifi Controller software (version 5.6 and earlier), the functionality of integrating the hostnames of clients (when they request a DHCP lease) into local DNS does not appear to work as you would find with Consumer grade routers. To work around this limitation, we can add static host mappings to a configuration file that will be provisioned to the USG when either a configuration change is made or we force provisioning to the USG itself.

Non-GUI Supported Dynamic DNS Providers

I've added in the necessary syntax for adding Cloudflare DDNS to the USG for VPN/Services setup courtesy of this post by britannic on the Ubiquiti Forums.
