ActiveRecord: Store Milliseconds (or Microseconds) in Timestamps with Rails / MySQL

Milliseconds in your Timestamps.

We got 'em, you want 'em.

Why

Shit needs to be PRECISE

Screen Quick Reference

Basic

Description	Command
Start a new session with session name	`screen -S <session_name>`
List running sessions / screens	`screen -ls`
Attach to a running session	`screen -x`
Attach to a running session with name	`screen -r`

This can be used to daemonize anything that would normally run in the foreground; I picked Redis. Put this in /etc/systemd/system/redis.service:

[Unit]
Description=Redis
After=syslog.target

[Service]
ExecStart=/usr/local/bin/redis-server /etc/redis/redis.conf
RestartSec=5s

Demo:

Spoiler warning

Spoiler text. Note that it's important to have a space after the summary tag. You should be able to write any markdown you want inside the <details> tag... just make sure you close <details> afterward.

console.log("I'm a code block!");

How many warnings should your JavaScript app have?

JavaScript warnings are these messages being displayed in yellow or red in your JavaScript console or terminal. They make no sense at all in general but they are a good indication of the health of your app. The points below will give you a general idea of how many warnings you should expect in your app:

0 warnings: the app is not working at all
5 warnings: app is probably starting but crashing soon after - try to find why it crashes. You'd think you could read the warnings to learn why it doesn't work, but that's not what warnings are for.
50 warnings: That's the soft spot - most likely everything's running smoothly
