Émission #72 du 20 novembre 2014 – Ça pas d’allure

Pour télécharger l’émission allez sur bloguelinux.ca : http://www.bloguelinux.ca/emission-72-du-20-novembre-2014-ca-pas-dallure/

Animateurs: Patrick, Éric et Sandrine

Ça pas d’allure

  • Expression Québécoise qui veut dire : Expression utilisée souvent par Éric pour pour d’écrire quelque chose d’impressionnant ou qui n’est pas normal (ça n’a pas de bon sens), c’est n’importe quoi.

Les nouvelles technos personnelles

Éric, Patrick et Sandrine échangent sur leurs expériences technologiques personnelles depuis la dernière émission

Quoi de neuf

Un excellent concept: ChooseMyPC génère une liste de composants pour PC à partir du budget que vous avez spécifié

Microsoft .Net Framework sera disponible sous licence Open Source (et ce ne sera surtout pas la GPL)

Les serveurs ARM arrivent à grand pas dans les datacentres (et Microsoft est en retard…)

Nouvelle technologie G.Fast de Broadcom qui permet d’obtenir 1 Gbps sur une paire de cuivre

FREEdi: Continuer à écouter la portion sonore en arrière plan d’une vidéo sur Youtube sur votre appareil Android (et iOS aussi).

Le Framework Xposed pour modifier Android à sa guise

Surprises

Things IT People Never Say

Des espadrilles, fortement inspirés par le film Back to the Future Part II, qui se noue par elle même, actuellement en financement participatif (mais il y a un bémol)
