    TurboVNC

    TurboVNC

    High-speed, 3D-friendly, TightVNC-compatible remote desktop software

    TurboVNC is a high-performance, enterprise-quality version of VNC based on TightVNC, TigerVNC, and X.org. It contains a variant of Tight encoding that is tuned for maximum performance and compression with 3D applications (VirtualGL), video, and other image-intensive workloads. TurboVNC, in combination with VirtualGL, provides a complete solution for remotely displaying 3D applications with interactive performance. TurboVNC's high-speed encoding methods have been adopted by TigerVNC and libvncserver, and TurboVNC is also compatible with any other TightVNC derivative. TurboVNC forked from TightVNC in 2004 and still covers all of the TightVNC 1.3.x features, but TurboVNC contains numerous feature enhancements and bug fixes relative to TightVNC, and it compresses 3D and video workloads much better than TightVNC while using generally only 5-20% of the CPU time of the latter. Using non-default settings, TurboVNC can also be made to compress 2D workloads as "tightly" as TightVNC.

    IDM Trial Reset

    IDM Trial Reset

    Use IDM forever without cracking

    IDM Trial Reset is a lightweight utility designed to reset the trial period of Internet Download Manager (IDM), allowing users to continue using the software without immediate license enforcement. Built using AutoIt, the tool automates registry and system-level modifications required to remove or reset trial-related data. It provides a simple interface or executable that performs the reset process without requiring deep technical knowledge from the user. The project emphasizes ease of use and portability, enabling users to run the tool whenever the trial period expires. While it does not modify the core IDM software, it interacts with system configurations to extend usability, and the repository encourages users to purchase a license if possible. Its open-source nature allows users to inspect or rebuild the executable themselves, increasing transparency.

    Barrier

    Barrier

    Open-source KVM software

    Barrier is a software that works just like a KVM (keyboard, video and mouse) switch, which allows you to use a single mouse and keyboard to control several different computers by physically turning a dial on the box to switch the machine you're controlling at any given time. Barrier is able to do this in software, giving you control over different machines by simply moving your mouse to the edge of the screen, or by using a keypress to switch focus to a different system. Barrier was built to be simple and reliable, allowing you to control a different machine by simply using your mouse and keyboard from another. It works on all major operating systems (Linux, Windows, MacOS/OS X), including FreeBSD and OpenBSD.

    An EFI boot manager utility

    rEFInd is a fork of the rEFIt boot manager. Like rEFIt, rEFInd can auto-detect your installed EFI boot loaders and it presents a pretty GUI menu of boot options. rEFInd goes beyond rEFIt in that rEFInd better handles systems with many boot loaders, gives better control over the boot loader search process, and provides the ability for users to define their own boot loader entries.

    ShredOS

    ShredOS

    Shredos Disk Eraser 64 bit for all Intel 64 bit processors

    For all Intel and compatible 64 & 32 bit processors. ShredOS is a USB bootable (BIOS or UEFI) small linux distribution with the sole purpose of securely erasing the entire contents of your disks using the program nwipe. If you are familiar with dwipe from DBAN then you will feel right at home with ShredOS and nwipe. What are the advantages of nwipe over dwipe/DBAN? Well as everybody probably knows, DBAN development stopped in 2015 which means it has not received any further bug fixes or support for new hardware since that date. Nwipe originally was a fork of dwipe but has continued to have improvements and bug fixes and is now available in many Linux distros. ShredOS hopefully will always provide the latest nwipe on a up to date Linux kernel so it will support modern hardware.
