Slack Tweaks

In Fall 2023, Slack introduced an updated client with some unpopular UI changes. The tweaks in this document can be used to revert to the old client or hide the new side bar. These will reset every time you fully close Slack but they are easy to re-apply once you get the hang of it.

(Cross Platform) Open Dev Tools [Preferred Option]

To run any of these scripts, you'll need to open the Dev Tools (or Console). You can do this by typing /slackdevtools in a Slack channel or direct message. These are the same Dev Tools you'd get in Chrome if you hit F12. Along the top are tabs for Elements, Console, Sources, Network, etc. You'll want to paste these scripts into the Console tab at the > prompt.

If Slack disables this command, then you can open Dev Tools by setting a system-wide environment variable and using a keyboard shortcut to open the console. If /slackdevtools worked for you then you can skip these next two sections.

(Mac OS) Enable Dev Mode

GitOps for Helm Users

Outline

Install Flux CLI and Kind
Make Personal Access Token for creating repositories
Export env vars locally
Create local demo cluster
Simple bootstrap
Clone the newly created git repo to your local workspace
Lets create a Helm release the most common way, using the Helm CLI

Terminal Colors

There exists common confusion about terminal colors. This is what we have right now:

Plain ASCII
ANSI escape codes: 16 color codes with bold/italic and background
256 color palette: 216 colors + 16 ANSI + 24 gray (colors are 24-bit)
24-bit true color: "888" colors (aka 16 milion)
