Celestia, Stellarium

ce sont deux logiciels très agréables à utiliser, et de plus, ils sont tous Open source (sous la GNU Public license) ! alors téléchargez-les sans souci.Celestia est plus libre en terme de navigation dans l'espace. il permet de tourner autour l'objet sélectionné (que ce soit un astre, une étoile, ou même une galaxie !) en d'autres termes, celestia présente l'univers en 3D. les images fournies sont de très bonne qualité, et permet aussi d'exécuter un script de navigation.Stellarium est plus sophistiqué. les images qu'il contient sont réelles, et permet d'installer un téléscope n'importe où dans le monde. vous allez regarder de vrais positions à de vraies résolutions et qualités. de plus, son interface paraît plutôt professionnelle. vous allez regarder l'univers comme si vous avez un téléscope chez vous.Une autre option intérressante : vous pouvez installer un téléscope sur une autre planète, en éditant un petit fichier nommé config.ini. pour le faire, rien de plus simple : Démarrer ->Tous les programmes->Stellarium->config.ini, et vers la fin du fichier remplacer Earth par exemple par Jupiter : vous obtenez un téléscope sur jupiter !A ne pas manquer. www.shatters.net/celestia

GNS3 on Manjaro/Arch Linux: How to create virbr0 for NAT to work

Problem: You can't add a NAT connection to your GNS3 simulation, and you get the error : "ERROR template_manager:226 Error while creating node from template: NAT interface virbr0 is missing, please install libvirt" Steps to resolve: 1- Create a file named /tmp/default.xml 2- Paste this content and save: <network> <name>default</name> <bridge name="virbr0"/> <forward mode="nat"/> <ip address="192.168.123.1" netmask="255.255.255.0"> <dhcp> <range start="192.168.123.2" end="192.168.123.254"/> </dhcp> </ip> </network> 3- Execute the following commands in your shell : virsh net-define /tmp/default.xml sudo virsh net-start default sudo virsh net-autostart default

GNS3: Simulating a 100% opensource site2site VPN using Wireguard, VyOS and OpenVSwitch

This is something I had in mind but didn't find the time to accomplish before. It just took a very cold day to convince me that I have to play with Wireguard on VyOS. I used GNS3 of course, on my personal Linux laptop to create this setup. Of course the performance was not that great since it is just a simulation. In real life, I am using Wireguard on a 10 years old Raspberry Pi Model B and amazingly with just a 700MHz single core ARM CPU and less than 512 MB of RAM I had a decent and stable permanent Wireguard tunnel. (My bandwidth would reach 24 Mbps without issue) Back to my simulation, this is what it looks like : Quick explanation: the VYOS routers labeled IPERF1 and IPERF2 are only used for an iperf3 test, which was able to reach about 50 to 60 Mbps each time. It ain't much but it was honest (and free) secure bandwidth! I won't get into the details of this setup but I will just post the two most important configurations : R-East and R-West : #### VYOS WireGuard Site

Old school tool for news (RSS): NewsFlash

Being an old school user who was very dependant on RSS feeds to keep me updated on my favourite subjects, I spent a lot of time looking for something that could do this in 2024. Surprisingly, I found a tool called "NewsFlash" which looks like it was tailored exactly for people like me, people who can't live without Slashdot , TheHackerNews and TechCrunch ! I am currently daily-driving Linux Manjaro for more than two years on my personal laptop (while unfortunately I have to work on a Win11 system for my regular job) and, being based on Arch Linux, the cutting edge community-driven Linux distribution, Manjaro is able to provide the latest and greatest opensource (and sometimes proprietary) software via its default repositories. You don't even have to do anything "geeky" to install NewsFlash (or any other package in the repositories) since the Pamac Software Manager is really becoming easy and powerful at the same time! This is NewsFlash, very simple and eas
