Running cron jobs in AWS Auto Scaling group is tricky. When you deploy the same code and configuration to all instances in the group, cron job would run on all of them. You may not want that. This script detects the first instance in the group and allows only this instance to run the job. IAM user used by this script needs to have permissions to…
#!/usr/bin/env ruby
require 'syslog'
require 'net/http'
require 'aws-sdk'
Syslog.open
AWS.config({
:access_key_id => '<iam user key>',
:secret_access_key => '<iam user secret>'

Migrate Redis data on Amazon ElastiCache
"""
Copies all keys from the source Redis host to the destination Redis host.
Useful to migrate Redis instances where commands like SLAVEOF and MIGRATE are
restricted (e.g. on Amazon ElastiCache).
The script scans through the keyspace of the given database number and uses
a pipeline of DUMP and RESTORE commands to migrate the keys.
Requires Redis 2.8.0 or higher.

macOS Mojave dynamic background re-implement as GTK+ background slideshow. Background images are changed to reflect the time of the day.
<!-- Instructions:
- Download and unzip Mojave dynamic background here: https://files.rb.gd/mojave_dynamic.zip
- Rename the extracted folder as "mojave-background" (Excuse the trouble but I renamed it on my machine and already use that path in the XML file)
- Save this xml file next to the Mojave background files
- Fix the path to the background images below (better using absolute path)
- Lastly, either:
+ GNOME: Use gnome-tweaks tool to select this XML as wallpaper (as default wallpaper settings won't let you choose wallpaper from custom path)
+ MATE: Go to background setting (in Appearance) > Choose +Add... > make sure **All files** filter is selected at the bottom right > Then choose mojave.xml
