PostgreSQL command line cheatsheet

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

  • -E: will describe the underlaying queries of the \ commands (cool for learning!)
  • -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

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

Set up the Nvidia GeForce GT 710 on Raspberry Pi Compute Module 4
#!/bin/bash
# Attempt to set up the Nvidia GeForce GT 710 on a Pi CM4.
#
# I have tried both armv7l and aarch64 versions of the proprietary driver, in
# addition to the nouveau open source driver (which needs to be compiled into
# a custom Raspberry Pi kernel).
#
# tl;dr - None of the drivers worked :P

A tutorial to use GUI in WSL2 replacing original XServer by Xvnc, allowing WSL to work like native Linux, including login screen

WSL2 with GUI using Xvnc

Note

If you want to use pure WSLg, you can try the new WSLg (XWayland) tutorial or the WSLg (Wayland) tutorial.

In this tutorial, we will setup GUI in WSL2, and access it using VNC. No additional software outside WSL (like VcXsrv) is required, except, of course, a VNC Viewer (RealVNC, TightVNC, TigerVNC, UVNC, etc, all of them might work flawlessly).

The key component we need to install is the desktop metapackage you want (GNOME, KDE, Xfce, Budgie, etc) and tigervnc-standalone-server.

For this setup, I will use Ubuntu (20.04, 22.04 and 24.04 are working), and install GNOME Desktop. Since the key components aren't bound to Ubuntu or GNOME, you can use your favorite distro and GUI. Check the [Sample

WSL 2 - Enabling systemd

Enable systemd in WSL 2

NOTE: If you have Windows 11 there is now an official way to do this in WSL 2, use it if possible - see MS post here (WINDOWS 11 ONLY)

This guide will enable systemd to run as normal under WSL 2. This will enable services like microk8s, docker and many more to just work during a WSL session. Note: this was tested on Windows 10 Build 2004, running Ubuntu 20.04 LTS in WSL 2.

  • To enable systemd under WSL we require a tool called systemd-genie

  • Copy the contents of install-sg.sh to a new file /tmp/install-sg.sh:

# Update things to be compatible with Molecule 3.0.
