7-Zip is a program for creating or unpacking archived and compressed files. It can unpack 7zip, ZIP, CAB, ARJ, GZIP, BZIP2, TAR, CPIO, RPM and DEB files, or create file archives in these formats.  For the standard ZIP and GZIP formats, 7-Zip provides compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip, and the native 7zip format can provide 45% reduction in file size from the common zip format. The program is highly configurable, allowing the user to balance the level of compression and speed.  The interface is designed to mimic the standard Windows shell, Explorer and is localised to 40 languages.



VirtualBox - is The Ultimate x86 cross-platform virtualization product from the desktop to the server. It allows you to run multiple operating systems (inside multiple virtual machines) at the same time. For example, it allows you to run Linux on Windows PC, or vise-versa, or run both Windows and Linux on your Mac.
For The Qumble community, the most valuable task VirtualBox offers is the ability to study the various Open-Source Operating Systems, such as Linux, right from your Windows desktop.
Screenshots show you several modes of operation: Normal mode (aka Windowed mode), where a virtual machine behaves like a normal application window, Seamless mode, where your real main operating system (Host) shares desktop with your virtual machine (Guest), and a normal mode with hardware 3D acceleration, where you can actually play some 3D games, and, if you're running Windows 7 or Vista guests, enjoy Windows Aero 3D Experience.


Scintilla Editor

SciTE, or The The Scintilla Text Editor, is an editor for writing or altering pure text files. It is not a word processor such as Office, but rather a light-weight yet powerful program that can serve as a Notepad replacement or a full-featured source code editor. In its standard form it has a simple and intuitive interface, which can be customised and can serve  as a development environment complete with syntax highlighting for over 40 file types, line numbering, bracket highlighting, and compiler output window.
    The tabbed layout allows you to open several files at once, to copy between them and to perform operations like search and replace on multiple files. The syntax highlighting feature is useful in editing web pages or program source code. Other features include line numbering, PDF export, word completion, multiple undo, full screen and split screen modes.
