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

Add on top of default.nix: with import {}; or simply run as nix-build '' (i. e. for nix-build complaining) or rather nix-build -E 'with import {}; callPackage ./default.nix {}' (or even import)

public class ConfigurationLoader {
  private final ObjectMapper objectMapper;
  private final StringSubstitutor stringSubstitutor;

  ConfigurationLoader() {
    this.objectMapper = new ObjectMapper(new YAMLFactory());
    this.stringSubstitutor =
        new StringSubstitutor(StringLookupFactory.INSTANCE.environmentVariableStringLookup());
  }

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns                     on recent CPU
L2 cache reference ........................... 7 ns                     14x L1 cache
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns                     20x L2 cache, 200x L1 cache
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs 4X memory
