Find Scaleway Image ID by Label

It could be difficult to find a Scaleway image ID for the right zone, architecture, and instance type. The Scaleway marketplace API has an endpoint dedicated to that but it could be difficult to understand the response and to find the right image UUID.

Here is a bash command that returns a JSON with just the necessary information needed to find your image ID.

curl -s 'https://api-marketplace.scaleway.com/images?page=1&per_page=100' | sed 's/par1/fr-par-1/g; s/ams1/nl-ams-1/g' | jq '.images | map({"key": .label | gsub("_";"-"), "value": .versions[0].local_images}) | from_entries'

Raspberry Pi Zero OTG Mode

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).

The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int
