SteamOS We've been hard at work to deliver on our promise of a new kind of living room entertainment environment - one that is accessible, powerful and open. In making SteamOS available to you, we're excited to take the next major step towards that goal. But before you dive in, please take a few minutes to understand what SteamOS is and what it is not. SteamOS is a public release of our Linux-based operating system. The base system draws from Debian 8, code named Debian Jessie. Our work builds on top of the solid Debian core and optimizes it for a living room experience. We expect most SteamOS users to get SteamOS preinstalled on a Steam Machine. Most importantly, SteamOS only supports a certain set of hardware (you can read more in our FAQ). Users should not consider SteamOS as a replacement for their desktop operating system. No. SteamOS uses the Advanced Packaging Tool system (APT) to manage software on a SteamOS machine.

The second operating system hiding in every mobile phone - Aurora I've always known this, and I'm sure most of you do too, but we never really talk about it. Every smartphone or other device with mobile communications capability (e.g. 3G or LTE) actually runs not one, but two operating systems. Aside from the operating system that we as end-users see (Android, iOS, PalmOS), it also runs a small operating system that manages everything related to radio. Since this functionality is highly timing-dependent, a real-time operating system is required. This operating system is stored in firmware, and runs on the baseband processor. The problem here is clear: these baseband processors and the proprietary, closed software they run are poorly understood, as there's no proper peer review. The insecurity of baseband software is not by error; it's by design. You can do some crazy things with these exploits. This is a pretty serious issue, but one that you rarely hear about.

Steam Trading Cards - Le nouveau concept de Valve | My Little Geekette Article mis à jour le mercredi 19 juin Il y a peu, Valve a donné accès à une bêta aux utilisateurs de Steam : Steam Trading Cards. Le concept est plutôt très simple : obtenir des cartes aléatoirement durant vos périodes de jeu. J’ai décidé de faire un petit article récapitulatif pour présenter cette bêta et en expliquer le fonctionnement. Dans les faits, le principe est ultra simple. A ce moment-là, on se demande surtout à quoi vont servir ces cartes. Profil sans personnalisation Chaque jeu participant à cette bêta aura un badge qui lui est rattaché directement. Les récompenses obtenues avec le badge seront : un fond d’écran aux couleurs du jeu pour personnaliser votre page de profil Steam et un petit émoticône encore en rapport avec l’univers du jeu. Profil avec un fond d’écran Car Steam a également mis en place, avec cette bêta, un système de niveau. Par la suite, par chaque palier de 10, il faudra rajouter 100 points d’expérience.

SteamOS SteamOS is our Linux-based operating system. The base system draws from Debian 8, code named Debian Jessie. Our work builds on top of the solid Debian core and optimizes it for a living room experience. Most of all, it is an open Linux platform that leaves you in full control. You can take charge of your system and install new software or content that you want. What are the SteamOS Hardware Requirements? Intel or AMD 64-bit capable processor 4GB or more RAM 200GB or larger disk NVIDIA graphics card AMD graphics card (RADEON 8500 and later) Intel graphics USB port for installation UEFI Firmware (recommended) How do I install SteamOS? There are two different installation methods for SteamOS.

Steam Dev Days Download SteamOS now — Valve's free Linux-based operating system releases Put on your boot partitions—the SteamOS beta has released to the public alongside the initiation of its beta program, which will put 300 prototype Steam Machines into the wild. For the estimated 7,129,999,700 of us not selected for that program, a living room machine running the new, free, Linux-based OS is still doable, though installing it may require some tinkering—Valve suggests you wait until 2014 unless you're an "intrepid Linux hacker." Challenge accepted . At the time of writing, Valve has not officially announced that SteamOS 1.0 "Alchemist" is available for download. We expect a page to go live at later today. [Update: it's live.] Unfortunately, that download will most likely fail right now. We'll be playing with SteamOS this weekend, and plan to have impressions and installation tips for you as soon as possible.

A Short Introduction to Operating Systems A Short Introduction to Operating Systems Author(s) : Mark Burgess Publication Date : December 2002 Notes Review: These are the lecture notes of Operating Systems, courtesy of Mark Burgess, a full professor at the Faculty of Engineering of University College Oslo, Norway. As with other lecture notes, these are relatively short (168 pages) for a subject traditionally covered in thick volumes. The notes cover most of the basic topics of operating systems, many which have only been covered superficially. Topics covered include: - key concepts, resources and sharing, resource management and spooling - single task - multi tasking and multi user - processes and threads - memory and storages, physical and virtual - networks, services and protocols - security, super users, firewall View / Download A Short Introduction to Operating Systems

Valve has just started the PC games race to zero Valve has just announced that developers will now be in charge of their own pricing on Steam. They can run sales, offer discounts and promote their games without talking a Valve representative. This is the beginning of PC games prices drifting downwards, with an endpoint of zero. Here’s why. The marginal cost argument In Chapter 3 of The Curve, I set out the economic arguments for why a digital product will tend towards a cost of zero over time. Let’s imagine a shoe factory supplying shoes to one small town. An entrepreneur sees that there is an opportunity to make $4 for every $1 he invests in a pair of shoes. In the world of digital, the marginal cost is zero, or as close to zero as makes no odds. There is an issue with Bertrand Competition: it excludes the impact of marketing; it assumes that one pair of shoes is as good as another pair of shoes; it doesn’t factor in the cost of comparison, or the cost of switching, all of which are real. The hardware argument Sort of.

SteamOS announced by Valve, a free operating system "available soon" for living room PCs Following up on its enigmatic announcement-of-an-announcement last week, Valve has unveiled SteamOS , a free stand-alone operating system “for living room machines.” The OS “combines the rock-solid architecture of Linux with a gaming experience built for the big screen,” according to the announcement. In-house streaming to a TV, similar to what's used in Nvidia's Shield , is a feature of the OS. Valve also emphasizes SteamOS's openness. A vague component of the announcement is Valve's claim to have “achieved significant performance increases in graphics processing” in SteamOS. Check back on Wednesday for the second of three announcements expected from Valve this week. Story by Tyler Wilde and Evan Lahti
