Install VNC Server on AWS Ubuntu Linux (For accessing a graphical environment)

Here is the link that will help you for doing that :

https://ubuntu.com/tutorials/ubuntu-desktop-aws#1-overview

Then from a Windows machine, download TightVNC at :

https://www.tightvnc.com/download.php

And when entering the remote AWS Ubuntu machine address in TightVNC, don't forget to append "::5901" at the end of the URL.


If you want to change the displayed resolution when connecting from TighVNC client, then, on the Ubuntu Linux machine do the following :

vncserver -kill :1

vncserver -geometry 1600x1200

And connect again from your TightVNC client on the remote (Windows) machine.

Find large files in command-line (WSL/Ubuntu 2004)

 find / -name * 2>/dev/null -type f -size +1000000


Ideas for troubleshooting WSL/Ubuntu2004 (LxssManager service)

 If you try to start your Ubuntu 20.04 LTS instance in the WSL environment on Windows (10), then try to restart the LxssManager service through Powershell as follows :

powershell

Restart-Service LxssManager

Restart-Service LxssManager -force

The following article might help to understand the mechanics around starting and stopping services through Powershell, in case you need it :

Basically, you should use the "Get-Service" function to list all services from Powershell.

Transmettre un signal radio AM depuis un PC sans aucun périphérique hardware !

En faisant une recherche sur la documentation NFT EIP721 je suis tombé sur la page suivante :

https://eips.ethereum.org/EIPS/eip-721

Un est auteurs est un certain William Entriken, et quand on clique sur son nom dans le document EIP721, on arrive sur un repository GitHub sur lequel on peut voir un projet "System-Bus-Radio".

https://github.com/fulldecent/system-bus-radio

Ce projet permets de jouer une petite mélodie qui est transmise sur une fréquence radio AM de 1580 Khz uniquement en faisant appel à des instructions du processeur !!!

Hallucinant !

Pour celles et ceux qui s'intéressent à ce sujet, voici un PDF à lire, qui a été déclassifié à la NSA en 2007 :

https://www.nsa.gov/portals/75/documents/news-features/declassified-documents/cryptologic-spectrum/tempest.pdf

Le titre de ce PDF est "TEMPEST: A Signal Problem The story of the discovery of various compromising radiations from communications and Comsec equipment."

Bonne lecture !
