Chromium Media Edition for RPi Pixel

Chromium sucks for streaming on the Raspberry Pi Pixel Desktop. One of my gripes was Youtube TV, ‘format not supported.’ Chromium Media Edition is much better. Ventz Petkov has a sweet install script. Here’s the tl;dr version.

curl -fsSL https://pi.vpetkov.net -o ventz-media-pi
sh ventz-media-pi

Famous 10 Minute WordPress Install

WordPress touts their install to be 5 minutes. I take it a step further. This script can take a freshly mint SD card and install a LAMP stack, phpMyAdmin, and WordPress in about 10 minutes.

Vivaldi for RPi Pixel

Chromium sucks for streaming on the Raspberry Pi Pixel Desktop. One of my gripes was Youtube, if I fast forward (hitting the arrow key) to advance through a video, ‘Aw, Snap!’ was sure to pop up. It’s a lot less of a problem if you’re over clocking. Chromium Media Edition has the same problem too. It’s not a problem if you’re using Vivalda.

Grab the Linux DEB ARM version.
