    Here’s what you’ll need to upgrade to Windows 11

    news.movim.eu / ArsTechnica · Friday, 25 June, 2021 - 20:05

Since Microsoft's announcement of Windows 11 yesterday, one concern has reverberated around the web—what's this about a Trusted Platform Module requirement?

Windows 11 is the first Windows version to require a TPM, and most self-built PCs (and cheaper, home-targeted OEM PCs) don't have a TPM module on board. Although this requirement is a bit of a mess, it's not as onerous as millions of people have assumed. We'll walk you through all of Windows 11's announced requirements, including TPM—and make sure to note when all this is likely to be a problem.

General hardware requirements

Although Windows 11 does bump general hardware requirements up some from Windows 10's extremely lenient minimums, it will still be challenging to find a PC that doesn't meet most of these specifications. Here's the list:

    Barrier – Contrôler plusieurs ordinateurs avec un seul clavier / souris

    news.movim.eu / Korben · Monday, 5 October, 2020 - 07:00 · 1 minute

Dans mes jeunes années, j’ai été un gros utilisateur de l’outil Synergy (2006 mon article, ça date) qui permettait d’utiliser plusieurs PC (Linux, Windows) avec un seul clavier et une seule souris.

Mais aujourd’hui, Synergy a bien changé et n’est plus gratuit. Heureusement la relève est là et s’appelle Barrier.

À l’origine, Barrier est un fork (un clone si vous préférez) de Synergy, dont le code est disponible sur Github et qui comme son parent permet d’utiliser un clavier et une souris sur plusieurs machines. Barrier imite le fonctionnement d’un switch KVM, mais de manière logicielle. Ainsi, lorsque vous déplacez la souris hors de l’écran de votre ordinateur, celle-ci arrive sur l’écran de votre second ordinateur.

Magique ?

Possible… Mais ça utilise surtout le réseau local pour ça, et Barrier permet de gagner un peu de place sur le bureau si vous avez plusieurs ordinateurs à dispo en ne conservant qu’un clavier et qu’une souris.

Barrier est disponible sous Linux ainsi que Linux ARM, donc Raspberry Pi, mais également macOS et Windows et comme il est assez proche de Synergy (avec moins de bugs que ce dernier), l’ensemble des tutoriels de l’époque sur Synergy, fonctionnent encore avec Barrier !

Good news !

Barrier est téléchargeable ici.

    Virtualization on the Linux desktop—Gnome Boxes vs virt-manager

    news.movim.eu / ArsTechnica · Thursday, 30 April, 2020 - 11:56 · 1 minute

We

Enlarge / We're not sure we love Boxes' offer to act as a RDP/VNC/Spice/SSH all-in-one client for remote systems that have nothing to do with your VMs. Convenient—or confusing? (credit: Jim Salter)

In the comments of our recent GhostBSD review , reader Enduzzer casually mentioned trying out the distribution in a Gnome Boxes VM. Linux's Kernel Virtual Machine has been a mainstay of my own system administration for more than a decade—but I use virt-manager , an excellent and deeply sysadmin-ish graphical management interface.

I generally describe virt-manager as "simple"—and in many ways it's much simpler than Boxes is—but there are different ways to interpret simplicity.

The integrated approach

Under the hood, Boxes shares the majority of its technical underpinnings with virt-manager: the libvirt virtualization API, the Linux Kernel Virtual Machine (KVM) hypervisor, and the qemu generic processor emulator. Virt-manager exposes those inner workings as much as possible while trying not to get them unnecessarily in the way.
