Katana : Multi-Boot Security Suite | Free software downloads The great Ars experiment—free and open source software on a smartphone?! Android is a Google product—it's designed and built from the ground up to integrate with Google services and be a cloud-powered OS. A lot of Android is open source, though, and there's nothing that says you have to use it the way that Google would prefer. With some work, it’s possible to turn a modern Android smartphone into a Google-less, completely open device—so we wanted to try just that. Before we begin, we have a few slight notes. But, wait... did we say we'd dump "all" services? These chunks of proprietary code come from the component manufacturers themselves (Qualcomm, Broadcom, Synaptics, Sony, Samsung), and seeing what's in them usually requires you to be a big developer with an NDA in place. The basics It starts with CyanogenMod (CM), what we're going with for our software build. There is a project out there called "Replicant," which is based on CyanogenMod and aims to build a completely open source version of Android. The basic phone stuff is taken care of.
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
Comparison of operating systems Because of the large number and variety of available Linux distributions, they are all grouped under a single entry; see comparison of Linux distributions for a detailed comparison. There are also a variety of BSD operating systems, covered in comparison of BSD operating systems. For information on views of each operating system, see operating system advocacy. General information Technical information Security Commands NOTE: Linux systems may vary by distribution which specific program, or even 'command' is called, via the POSIX alias function. Jump up ^ This feature is still in development, see .Jump up ^ The nice command utilizes the setpriority() system call, which affects I/O priority, see OS X man page .

A Catalog of Operating Systems This is a classified, alphabetic listing of most operating systems, past and present, that have been distributed commercially or reported in the English-language literature. This extensive catalog is included because we believe that for the serious student who wishes to understand OS implementation, there is no substitute for studying a variety of actual systems. Most of the systems in this catalog have something to teach, and in many cases the best explanations are given by designers or users in the published literaure. The listing attempts to be as comprehensive as possible. However, it does not always distinguish closely-related versions or releases of the same OS, or reimplementations of substantially the same OS on different computers. Listed systems are limited to those which have actually been implemented (although perhaps only once), directly control the CPU hardware, and are general-purpose, at least within broad application areas (including business and real-time control).
www.centos.org - The Community ENTerprise Operating System Operating System List 309 words [ 5 Weblinks ] - Last update: 2013-10-14 Page created: 2004-04-03 [SB][MF] List of Operating Systems For interested persons is this list, in order to specify as much as possible operating systems already existing. Who would like to know whether the operating system with the name xyz really exists or has existed, this is a excellent source to start. Commercial, free, open source and operating systems developed at universities as well as their derivatives are included. This list offers hundreds of operating system product and project names, many of them are based on the same operating system more or less with more or less differences in the source code. Operating System not found? You are welcome to inform me about missing operating systems to nearly complete this list. Operating systems (592) Linux distributions (611)
Comparison of Linux distributions Technical variations of Linux distributions (called GNU/Linux by members of the free software movement) include support for different hardware devices and systems or software package configurations. Organizational differences may be motivated by historical reasons. Other criteria include security, including how quickly security upgrades are available; ease of package management; and number of packages available. These tables compare each actively and noteworthy distribution's latest stable release on wide-ranging objective criteria. It does not cover each operating system's subjective merits, branches marked as unstable or beta, nor compare Linux distributions with other operating systems. General Basic general information about the distributions: creator or producer, release date, latest version, and such. Cost The majority of Linux distributions are available without cost.

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.
List of Free Operating Systems: Download Now! There are an increasing number of equipment manufacturers and technology groups that provide operating systems (OS) for free personal and commercial use without any cost or fee. You are sometimes even free to use them, change their source code and redistribute them as well. Like Anything that comes for free, do not expect fancy printed manuals and CD-ROMs and technical support. Yet you can count on the community that uses these OS to provide you support through chat rooms and forums and mailing lists. You will also note that the size of these OS range from 1 to 10 GB so if you don’t have decent broadband connection, paying for a DVD/CD-ROM might seem reasonable. Also if you are not that techie, some of these companies offer helpdesk and support contracts, which can be bought at a reasonable price. FreeDOS These days, there are three main uses for FreeDOS: FreeDOS should run on any standard PC, but if you are new to DOS, we recommend you use a PC emulator to install and boot FreeDOS. RxDOS
Free Operating Systems That Aren't Linux - Software - Open Source We look beyond the traditional open source OS of choice to other free options such BSD, OpenSolaris, HaikuOS, ReactOS, and PureDarwin. The words free and open source operating system usually bring one stock answer to mind: Linux. But Linux isn't the only FOSS OS out there, and in fact hasn't been for some time now -- it's just the one that's most immediately associated with the label. Here's a survey of other operating systems that have also been built as open source products, are free to use, and generally come with little to no restrictions over their use. So how useful are these operating systems? What's crucial is that the work being done on all of them is openly available for any and all who want to run, deploy, adapt, transform, or build upon the work done there. First, there was UNIX -- and then, not long after that, BSD. Apart from being highly polished and mature code, one of BSD's biggest advantages is its extremely liberal licensing. 1 of 5 More Insights
The Best Free Software of 2011 - Operating Systems For years, PCMag has brought you an ever-bigger, ever-better list of desktop software that will cost you absolutely nothing. As of last year, we shook things up a bit. Instead of an annual look at the best free software, we went monthly. Since software can cost thousands, you might wonder why and how you can score immensely useful programs for free. We're throwing in all the worthy apps that run on Windows 7 and 8, the latest MacOS, and of course, the cloud-based Web apps that run in a browser like Chrome, Firefox, or IE to use anywhere. Look for a new category of free software titles every month. Topics from 2014:
