    VeraCrypt

    VeraCrypt

    Open source disk encryption with strong security for the Paranoid

    VeraCrypt is a free disk encryption software brought to you by IDRIX (https://www.idrix.fr) and based on TrueCrypt 7.1a. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt. This enhanced security adds some delay ONLY to the opening of encrypted partitions without any performance impact to the application use phase. This is acceptable to the legitimate owner but it makes it much harder for an attacker to gain access to the encrypted data. All released files are PGP signed with key ID=0x680D16DE, available on key servers and downloadable at https://www.idrix.fr/VeraCrypt/VeraCrypt_PGP_public_key.asc VeraCrypt can mount TrueCrypt volumes. It also can convert them to VeraCrypt format. Documentation: https://www.veracrypt.fr/en/Documentation.html FAQ : https://www.veracrypt.fr/en/FAQ.html

    EE Keeper

    EE Keeper

    EE Keeper is a saved game editor for Baldur's Gate Enhanced Edition.

    EE Keeper is saved game editor for Baldur's Gate: Enhanced Edition and Baldur's Gate II: Enhanced Edition. This project is a continuation of Shadow Keeper, originally released by Aaron O'Neil in 2000 for Baldur's Gate II: Shadows of Amn and Throne of Bhaal. This version will still work with the original BG2. Currently, it will only work natively on Windows, although it has been tried through Wineskin on Mac OS X and currently works, though no guarantee is in place that this will continue to be. Maximising that support is a priority, however. Please note: unless otherwise stated, EE Keeper will be archived in Zip format and uploaded. Please note, any support ticket that is created should be watched in case any extra information is needed. If you do not plan to keep and eye on your ticket and you have an account on the official Baldur's Gate forum, please be sure to provide your user name with the ticket in case any further information is required.

    QP Real-Time Event Frameworks & Tools

    QP Real-Time Event Frameworks & Tools

    Real-Time Event Frameworks based on active objects & state machines

    QP real-time event frameworks (RTEFs) provide lightweight, modern, event-driven architecture based on asynchronous Active Objects (Actors) and Hierarchical State Machines. The matching QM model-based design tool and other host-based tools complement the QP frameworks by supporting graphical modeling, code generation, software tracing, and unit testing for event-driven embedded software. Visit https://www.state-machine.com for more information. The QP RTEFs can run on bare-metal microcontrollers, replacing a traditional RTOS. The frameworks contain a selection of built-in real-time kernels (RTOS kernels), such as the cooperative QV kernel, the preemptive non-blocking QK kernel, and the unique preemptive, dual-mode (blocking/non-blocking) QXK kernel. Native QP ports and ready-to-use examples are provided for ARM Cortex-M (M0/M0+/M3/M4/M7/M33/...) as well as other CPUs. The QP RTEFs can also work with many traditional RTOSes and General-Purpose OSes, such as Linux and Windows.
