UniFi AP Buyers Guide

(updated May 2025)

The APs in this list are ordered from highest to lowest performance. However, unless you have a very high number of devices you likely do NOT need to buy the most expensive, highest performance AP. You can also check Ebay for deals, especially on older equipment.

All APs in this list support both wired backhaul and mesh modes. However, wired connections are strongly recommended for better performance and reliability.

Number of spatial streams are listed in order of 2.4GHz, 5GHz, 6GHz.

Good Choices:

=ROUND( A2/(1024)^(FLOOR(log(A2)/log(1024))), 2) & " " & SWITCH( FLOOR( log(A2) / log(1024) ) ,0,"Bytes",1,"KiB",2,"MiB",3,"GiB",4,"TiB")

This gist contains lists of modules available in

Python 3.10
Python 3.9
Python 3.8
Python 3.7
Python 3.6
Python 2.7

in AWS Lambda.

FutureStack 14 notes

Best talks day 1

Taming the Modern Datacenter, Mitchell Hashimoto, Hashicorp
- look at the future of CM systems using Terraform, moving up a level from managing per-machine resources, enabling Infrastructure as Code for the modern distributed data center (mix of IaaS like AWS/DO, PaaS like Heroku, and SaaS for things like DNS and email); I'm a bit skeptical all the complexity of Terraform is significantly better than a minimal layer of glue code to wire up different APIs together.. still interesting though
Towards a Data Driven Product, Techniques and Tools at GitHub, JD Maturen, GitHub
- covered the basics of data science & analytics, gave some insights into how GitHub does it
Understanding Developers in a Post Agile Environment, Ward Cunningham (inventor of wiki), New Relic
some interesting ideas on how to become a master engineer, "leveraged activities" vs. normal activities,

Open the postgresql.conf config file:

$> mate /usr/local/var/postgres/postgresql.conf

Uncomment the line with 'log_destination' and set it to 'syslog'

log_destination = 'syslog'

Open the syslog config:

	#/bin/bash

	gh auth login --with-token < token.txt

	#AUTHOR is the github name
	#JIRA_ID is on the tin
	#GH_TOKEN
	#JIRA_TOKEN

	Notes to make IR shield (made by LinkSprite) work in Raspberry Pi 3 (bought from Amazon [1]).
	The vendor has some documentation [2] but that is not complete and sufficient for Raspbian Stretch.
	Following are the changes that I made to make it work.

	$ sudo apt-get update
	$ sudo apt-get install lirc

	# Add the following lines to /etc/modules file
	lirc_dev
	lirc_rpi gpio_in_pin=18 gpio_out_pin=17
