Using an undocumented (and thus subject-to-change) API, provides a list of all AWS services colourised as to whether or not they're available in the given region. Alternatively, given two regions, colourised based on whether services are available in one region, both regions, or neither of them.

Wireguard Optimal MTU

About

  • I faced bandwidth issues between a WG Peer and a WG server. Download bandwidth when downloading from WG Server to WG peer was reduced significantly and upload bandwidth was practically non existent.
  • I found a few reddit posts that said that we need to choose the right MTU. So I wrote a script to find an optimal MTU.
  • Ideally I would have liked to have run all possible MTU configurations for both WG Server and WG Peer but for simplicity I choose to fix the WG Server to the original 1420 MTU and tried all MTUs from 1280 to 1500 for the WG Peer.

Testing

  • On WG server, I started an iperf3 server
  • On WG peer, I wrote a script that does the following:
    • wg-quick down wg0
  • Edit MTU in the /etc/wireguard/wg0.conf file

Yabai configs

This is my current (as of 4/30/2020) Yabai and skhdrc config as well as the Ubersicht (http://tracesof.net/uebersicht/) widget I use rather than the Yabai status bar. I went this route rather than the built-in status bar because I didn't like how Yabai as of 2.0.1 handled multiple monitors in the status bar.

Nothing is too far from defaults here, and the spaces.coffee was something I found linked in an issue on Yabai's github page.
