Using Unifi 5G Max with T-Mobile Home Internet

Caveats before I go further:

This probably just voided the warranty on a $400 device
It's possible that firmware updates or other processes could make this stop working at any time. The IMEI is an identifier on the modem's memory, not the Unifi memory.
Modification of IMEI may not be legal where you live. You should do your own research before going further.
If you are doing all of this work you should probably just look at DIY-ing with an M.2 RM551E or similar and a PoE adapter...
It is entirely possible (and likely) that T-Mobile (already) recognizes this activity for what it is and may take action against your account. IMEI is far from the only metric that networks have for profiling their clients. For what it's worth though, there are a good number of reports of people using 3rd party modems on TMHI for many years now with no issues. YMMV and that can change at any time.

Kubernetes on DigitalOcean with CoreOS

Let's look at an example of how to launch a Kubernetes cluster from scratch on DigitalOcean, including kubeadm, an Nginx Ingress controller, and Letsencrypt certificates.

Overview

Environment

We'll be creating a four-node cluster (k8s-master, k8s-000...k8s-002), load balancer, and ssl certificates.

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).

Profiling an application in Mac OS X

Finding which process to profile

If your system is running slowly, perhaps a process is using too much CPU time and won't let other processes run smoothly. To find out which processes are taking up a lot of CPU time, you can use Apple's Activity Monitor.

The CPU pane shows how processes are affecting CPU (processor) activity:

Deploying pypy on uwsgi

Instructions are kind of sporadic around the internet, so I thought I would gather them all in one place. The following example uses a Flask app as the thing deployed. You should only have to this once, and then you can pass the bin around.

Requirements

pypy 2.x (tested)
uwsgi 1.9.11+ (trunk as of this gist)
