Z‑Image Turbo is a bit different from “classic” Stable Diffusion, so a lot of old prompting habits don’t quite apply. I’ll walk through how to prompt it deeply and safely, with special focus on controlling content (nudity, stereotypes, unwanted artifacts) even though the model does not support traditional negative prompts at all. ([Hugging Face][1])

1. How Z‑Image Turbo thinks (and why “negative” prompts don’t work)

Key facts that matter for prompting:

Setting up VS Code and Golang with debug & build flag (-tags foo) support

This is the setup that worked for me after half a day of hacking around and chasing rabbit holes down old forum posts and open & closed Github issues.

Problem: While Go integration with VS Code is pretty slick in general, I needed to pass compile-time build flags, e.g., -tags foo[^1] to go build and go run directives, and I wanted to be able to properly debug with breakpoints etc. While there are some promising tutorials out there like this on Digital Ocean and on Log Rocket it turned out that one of the first things they both say to do is add the Delve extension to VS Code,

This Gist is based on Self Signed Certificate with Custom Root CA gist.

It adds the use of AWS KMS to generate and decrypt the Root CA private key, so that this key does not need to be stored in plaintext. Instead, the key is stored encrypted, and is being decrypted using AWS KMS only when needed.

Create AWS KMS CMK - Done Once

Create symmetic CMK (customer-managed key) and give it an alias of alias/root-ca-encrypting-key that will be used later to reference to it:

If you're using a high-end bluetooth headset on your Macbook Pro it's likely your mac is using an audio codec which favors battery efficiency over high quality. This results in a drastic degradation of sound, the SBC codec is the likely culprit, read more about it here.

Find out what codec you're using

1. Play a song on your headphones
2. Option (⌥) click the Bluetooth button at the top of your screen
3. If you're using AAC or aptX, you can stop here—those are the highest quality codecs.

Change your codec to AAC or aptX
