workaround for downloading rds logs via the AWS REST interface. This uses the IAM credentials for the session so should 'just work' on a lambda without needing to hardcode credentials/pass them in via environmental variables etc.
"""
Craft a web request to the AWS rest API and hit an endpoint that actually works but isn't supported in the CLI or in Boto3.
Based on this: https://github.com/aws/aws-cli/issues/2268#issuecomment-373803942

Renew Expired GPG key

Renew GPG key

Given that your key has expired.

$ gpg --list-keys
$ gpg --edit-key KEYID

Use the expire command to set a new expire date:

Erlang honors cgroup CPU quota from Erlang 23. But when less than 1 CPU is used, schedulers_online will be cores number(see below k8s 0-5).

$ docker run --rm -it --cpu-period 100000 --cpu-quota 100000 erlang:23 bash

Increase the BAR memory address space for PCIe devices on the Raspberry Pi Compute Module 4
#!/bin/bash
# The default BAR address space available on the CM4 may be too small to allow
# some devices to initialize correctly. To avoid 'failed to assign memory'
# errors on boot, you can increase the range of the PCIe bus in the Raspberry
# Pi's Device Tree (a .dtb file specific to each Pi model).
#
# You should probably read up on Device Trees if you don't know what they are:
# https://www.raspberrypi.org/documentation/configuration/device-tree.md

How to set up an OpenWRT VM in Proxmox
  1. Go to OpenWRT release page, select the latest release stable release, then targets -> x86 -> 64. Right-click generic-ext4-combined.img.gz (not the "efi"!) and copy the link.

  2. On the Proxmox host, download the archive and unpack it:

wget *paste link here*
gunzip openwrt-*.img.gz
  1. Resize the image to be the size you want your VM's disk to be (example with 8 GiB):
