    uumate

    uumate

    Updated Ubuntu Mate OS 64bit (15.10 based)

    UUMATE is a respin of Ubuntu Mate (https://ubuntu-mate.org/) The main goal of this project is simple: Just have an updated Ubuntu Mate 64bit ready to install, with full multimedia support, compiz, many extra applications and some cosmetic changes. Many PPAs/Repos already available. Event sounds (minimize, maximize, close, etc...) enabled by default you can enable/disable compiz using "mate-tweak"! No need to download hundred megabytes after installation! Note: To burn the ISO to a USB stick, use "dd" command. In MS Windows use Rufus. This ISO is helpful for people trying to install linux for the first time or coming from windows environment. It has plenty of software pre installed (some are trial/shareware) with full internet and multimedia support. Very useful as live media as well. It has audio/video codecs, flashplayer, java, googletalk, telegram, twitter, etc... Changelog: http://sourceforge.net/p/uumate/blog

    ELKS is a subset of the Linux kernel that runs on IBM compatible PCs from 8086 up. It is intended to get use out of obsolete old hardware, for use in embedded systems, and as an educational tool. ELKS has been moved to Github to protest SourceForge's installer adware hijacking. This does not directly affect ELKS, but it does affect many major open source projects such as Gimp and FileZilla by attempting to trick the user into installing adware in order to download these programs. I refuse to leave ELKS here with such policies in effect. If you have questions about this, please email jody@c02ware.com.

    Genode OS Framework

    Genode OS Framework

    Tool kit for building highly secure special-purpose operating systems

    *** Genode migrated to https://github.com/genodelabs/genode *** The Genode OS Framework is a tool kit for building highly secure special-purpose operating systems. It scales from embedded systems with as little as 4 MB of memory to highly dynamic general-purpose workloads. Genode is based on a recursive system structure. Each program runs in a dedicated sandbox and gets granted only those access rights and resources that are needed for its specific purpose. Programs can create and manage sub-sandboxes out of their own resources, thereby forming hierarchies where policies can be applied at each level. The framework provides mechanisms to let programs communicate with each other and trade their resources, but only in strictly-defined manners. Thanks to this rigid regime, the attack surface of security-critical functions can be reduced by orders of magnitude compared to contemporary operating systems.
