How to make an MDM Mac shine like it's brand new ?

Works, as of 14/04/2024, on macOS 14.4.1 and lower (prob higher but idk)

This was made for Apple Sillicon Macs.

Restore Process

You need another Mac for this.

If you don't have one and have recovery locked, it's not possible.

Setting up Heroku and Cloudflare (the right way)

The following outlines how to setup Heroku + Cloudflare with a full SSL certificate. What this means is that communication between the browser and the Cloudflare CDN is encrypted as well as communication between Cloudflare and Heroku’s origin server. Follow these steps exactly and the setup is a breeze.

Step 1: Set up domain names in Heroku

First you want to add the root domain and the www domain to heroku. You do this by clicking into your production application, then going to settings and then scrolling down to Domains and certificates.

Here you will add <your_domain>.com and www.<your_domain>.com. This will give you two CNAME records. They will look something like <your_domain>.com.herokudns.com and www.<your_domain>.com.herokudns.com.

Step 2: Add CNAME records to Cloudfare.

Cloud-Init Debugging

Cloud-init combined with terraform can be a powerful tool to provision instances on startup. Debugging scripts that are run by cloud-init however are not the easiest to debug.

Logs

Usually on an Ubuntu machine a lot of what is happening can be found in the syslog

cat /var/log/syslog

Generating Authy passwords on other authenticators

*update: TBC, but this new might affect how easy it is to use this technique past August 2024: Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August

This gist, based in part on a gist by Brian Hartvigsen, allows you to export from Authy your TOTP tokens you have stored there.
Those can be "standard" 6-digits / 30 secs tokens, or Authy's own version, the 7-digits / 10 secs tokens.

ANSI Escape Sequences

Standard escape codes are prefixed with Escape:

Ctrl-Key: ^[
Octal: \033
Unicode: \u001b
Hexadecimal: \x1B
Decimal: 27

List of good image generator training logs

A list of public training logs from neural network image generation models, since I think they're interesting.

The Criteria

Publicly accessible link
Losses plotted every so often
Samples generated every so often
Nontrivial dataset (i.e. not MNIST - 64x64 output RGB or better)

ghcr (GitHub Container Registry) quickstart

CLI

To push container images to ghcr, you need peronal access token (PAT) - see how to create PAT

Get PAT (personal access token)
