Force 5 GHz WiFi Connection on macOS

If you're experiencing issues with your Mac connecting to the slower 2G band on routers that share SSID between 5G/2G (like the Google Wifi Nest), here's a guide to help you force a 5 GHz connection.

Identifying the 5G Channel

1. Check Current Band: Hold option and click on the wifi icon on the macOS status bar. This will display the band you are currently connected to.
2. Scan WiFi Channels: Use the following command to list all channels your WiFi is operating on:

   /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport scan

Tired of spamming Yubikey one-time password (OTP) codes into Slack? Here are two options to help prevent that. You can do either or both. Both require ykman, the Yubikey CLI configuration manager. Get it with Homebrew:

brew install ykman

If you…

• …don't have Homebrew? Install it, then run the command above
• …don't feel comfortable running terminal commands? Skip to the bottom
• …aren't sure what the big deal is? See "What's the big deal with Yubikey codes?" below

Probably one of the easiest things you'll ever do with gpg

Install Keybase: https://keybase.io/download and Ensure the keybase cli is in your PATH

First get the public key

keybase pgp export | gpg --import

Next get the private key

Golang Workers / Job Queue

A running example of the code from:

• http://marcio.io/2015/07/handling-1-million-requests-per-minute-with-golang
• http://nesv.github.io/golang/2014/02/25/worker-queues-in-go.html

This gist creates a working example from blog post, and a alternate example using simple worker pool.

TLDR: if you want simple and controlled concurrency use a worker pool.
