    MultiBootUSB-Live

    MultiBootUSB-Live

    Portable System for installing many Linux Distros on to a Pen drive

    This project provides a Live DVD for the multibootusb program, for installing multiple Linux Distros on to a single Pen drive and able to boot from it. This is a portable system, which does not require any installation. Video Below. This system can be started through the DVD Drive OR VirtualBox (See Below). This .iso file can also be written on to a small dedicated pen drive ( ~ 1 GB ) through this DVD's multibootusb program and further used for writing linux images on to other pen drives ( not on the same ! ) thereby making everything portable. Note: Click "+ Other Locations" on the file manager for opening local disks, while browsing for images to write through this dvd's multibootusb program. Also note that the pen drive needs to be in fat32 format for proper booting. if in other formats, for eg. ntfs, you can use the GParted program that is in this dvd, to reformat it to fat32 ( will cleanup all data ). Watch https://www.youtube.com/watch?v=CjQRkISnHQ4 before format. See Wiki

    Pearl Pantheon 7.1

    Pearl Pantheon 7.1

    Pearl on the Pantheon DE with KODI + the Pearl GNOME Session

    Pearl's first Pantheon release. The Pearl 7.1 base (18.04) is where this version starts but has many familiar features the folks familiar with Elementary OS and will feel at home but not quite because as Usual we like to twist it up a bit. The just released of Elementary OS is great and now the Pearl Linux version of Elementary OS with the standard Pearl defaults including compiz for desktop effects available threw the Pearl Window Manager Switcher. For updates we chose to not use the normal way we do updates on other current Pearl releases which is by means of PearlUpdate, which is our version of MintUpdate from Linux Mint. Updates are handled with the default of the Pantheon Desktop Environment to keep the Elementary OS feel as default. Easily installs UEFI on older Mac Book Pro's. For the inexperienced, after install just create a ReFind bootable usb thumb drive available on https://sourceforge.net/projects/refind/files/0.11.4/refind-flashdrive-0.11.4.zip/download

    Pearl Linux Surf

    Pearl Linux Surf

    Quick booting OS Built for live usb web browsing

    Pearl Surf was designed to run from a usb thumb drive made the the Ubuntu USB-Creator. We included all you need to start browsing with Chromium and Thunderbird for an email client. Also included for added multimedia functions is Clementine, Banshee and totem. I decided that I was not looking to have the fastest loading live OS as from what I see is all anyone is concerned about, but to acually take a full minute maybe even 1.5 to load and have a decent OS to work with. It loads very fast on many types of systems we check our systems on from net books to all brands of desktops. This is also a great system for you to add software of your choosing for your own custom built system. Ubuntu Software Center is installed for you to add to this lightweight release of Pearl. Java and Flash support built in.

    Cloudium OS

    Cloudium OS

    Written in pure ASM and Exode with cloud computing in mind.

    Cloudium OS is being written in pure ASM. It's designed for speed and ease, having cloud computing in mind. It also is secure (without requiring constant user input like Windows). But, how are we going to do this? Well every os wants/says these kind of things, so to accomplish our goals we follow these simple rules: keep it simple (that's way better then these complex interfaces etc. almost nobody wants), generalize (this makes things easier and more useful without extra complexity) and be inventive (sometimes doing it the classical way just doesn't work). Note: development peace will be temporarily lowered until February the fifth. Please check out our OS and Project site!

    GRUB4USB

    GRUB4USB

    GRAND UNIFIED BOOT LOADER FOR USB

    FOR WINDOWS USERS WHO WANT TO JUMP TO LINUX EASILY/PAINLESSLY WITH A FAST BOOTING USB FLASH DRIVE. LATEST VERSION AT www.grub4usb.com A simplified "FAMILY TREE"/"Ancestor" perspective: www.grub4usb.com for more. Introduction (from http://www.gnu.org/software/grub/) GRANDPA: GRUB is a Multiboot boot loader. It was derived from GRUB, the GRand Unified Bootloader, originally by Erich Stefan Boleyn. DAD: GRUB4DOS made it easier for Windows/DOS users, but was still unreliable; the boot record was difficult to install for average users. GRUB4USB was developed to automate the installation of the correct 446 bytes to the boot sector, providing Windows Users with a bootable USB Flash Drive which could contain any flavor of Linux (or other OS). IDIOT PROOF: GRUB4USB is "AUTOMATIC AND HANDS FREE". Simply insert USB Flash Drives, they're detected, the boot record is installed with a Linux distribution to quickly create functional, bootable USB Flash Drives; aka LIVE USB.

    Solarstorm

    Solarstorm

    A rethinking of the Operating System Ecosystem.

    This is the fifth or sixth generation of this idea, the big difference being that we have written some bootloader code and have started mapping out the kernel layout and structure. We have decided upon a core programming language for the kernel, and the core language for almost everything else. With a focus on isolating the MAJOR kernel features from the system itself, in what until now has remained research only instances, we hope to create a fully functioning exokerne. All code at this time will be available only via a git repository.
