Negative Python user experience on Debian/Ubuntu

The user experience of Python on a minimal Debian or Ubuntu installation is bad. Core features like virtual environments, pip bootstrapping, and the ssl module are either missing or do not work like designed and documented. Some Python core developers including me are worried and consider Debian/Ubuntu's packaging harmful for Python's reputation and branding. Users don't get what they expect.

Reproducer

The problems can be easily reproduced with official Debian and Ubuntu containers in Docker or Podman. Debian Stable (Debian 10 Buster) comes with Python 3.7.3. Ubuntu Focal (20.04 LTS) has Python 3.8.5.

How to set up static nspawn IP address networking without a bridge

Note - this article assumes you have reasonable familiarity with systemd, networkd and nspawn/machinectl

What is this guide for

There seem to be a lot of references on the internet for nspawn networking with a bridge - but not on simply using the stock veth networking with static addresses. The default behaviour of nspawn (as of 24/03/20 and systemd:245 on Arch) is to:

Make a virtual ethernet port on the host (defined by /lib/systemd/network/80-container-ve.network)
Make a virtual ethernet port in the container (defined by /lib/systemd/network/80-container-host0.network)
Based on those configurations, serve the host port a random IP from the local network ranges with a 28 bit subnet, and a DHCP server for the host port serves a random IP in the subnet to the container

Backup android app, data included, no root needed, with adb

Note: This gist may be outdated, thanks to all contributors in comments.

adb is the Android CLI tool with which you can interact with your android device, from your PC

You must enable developer mode (tap 7 times on the build version in parameters) and install adb on your PC.

Don't hesitate to read comments, there is useful tips, thanks guys for this !

Dumping games with Godmode9

Dumping games is the act of taking a game from your system or gamecart and copying it into a readable format onto your SD card. Dumping is perfectly legal if you keep the dumps to yourself, however sharing these dumps is piracy and is illegal.

This guide will tell you how to dump games from various formats and for various purposes. Dumping 3DS cartriges as .cia files is good if you want to install them to your system. Dumping them as .3ds files is good for emulators. Installed titles cannot be dumped as .3ds files. NDS cartiges can only be dumped as .nds files and cannot be installed (however, you can play them with emulators or flashcarts).

Dumping the RomFS of a game is primarily for romhacking purposess.

A SaltStack AWS Auto Scaling Solution

Overview

The AWS Auto Scaling Goup, configured with a customised Cloud-Init file, sends a notification to an SNS Topic, which in turn passes it onto an SQS queue that the Salt Master is subscribed to. A Reactor watches for the auto scaling events and pre-approves the new minion based on its Auto Scaling group name and instance ID.
