Plex Media Permissions for Linux Noobies

There is no problem with being a noobie and I do not use the term to sligtht or disparage anyone.

This is a way to setup your permissions for running Plex in Linux. Different folks may use different methods.

The permissions concepts provided here apply to OSX, but the users and groups are controlled and modified differently, so much of this will not work properly. I think the command is dscl, but that could be out of date.

There are many ways to setup your permissions scheme in Linux, this methodology describes a way to do it, not everyone will like it, but it works for me, so whatever.

Docker compose as a systemd unit

Create file /etc/systemd/system/docker-compose@.service. SystemD calling binaries using an absolute path. In my case is prefixed by /usr/local/bin, you should use paths specific for your environment.

[Unit]
Description=%i service with docker compose
PartOf=docker.service
After=docker.service

1 - Create a extensions for String with a new, wonderfull, superpower method called crop:

extension String {
    func crop(from: Int, length: Int) -> String! {
        let startIndex = self.index(self.startIndex, offsetBy: from)
        
        var result = self.substring(from: startIndex)
        
        let endIndex = result.index(result.startIndex, offsetBy: length)
 result = result.substring(to: endIndex)

Tabs and Windows

Function	Shortcut
New Tab	`⌘` + `T`
Close Tab or Window	`⌘` + `W` (same as many mac apps)
Go to Tab	`⌘` + `Number Key` (ie: `⌘2` is 2nd tab)
Go to Split Pane by Direction	`⌘` + `Option` + `Arrow Key`
Cycle iTerm Windows	`⌘` + `backtick` (true of all mac apps and works with desktops/mission control)

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

The introduction to Reactive Programming you've been missing

(by @andrestaltz)

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

I turned my Raspberry Pi into a robot, controlled by a Wii nunchuk. It's surprisingly easy to do - at least, surprisingly to me, who has not previously made a robot. But because it's surprising, it might help others to have a guide, so here one is.

Parts

I'm linking to SKPang for most of these, but Sparkfun and Adafruit would be good places to look if you're in the US.

(If you're in the UK, a word of caution - I bought motors and some other stuff from Sparkfun to save £7 over SKPang, but the package got stopped at customs and I had to pay £4 VAT and £8 handling fees. My understanding is that this will only happen on packages whose contents are worth more than £15, but you'd be a fool to trust me on this. It didn't happen when I spent £20 at Adafruit or £5 at Sparkfun. YMMV.)

Raspberry Pi - for the robot logic. An Arduino or similar could be substituted (though the software would need to be rewritten).
