Consh is a set of programs that can turn one or more UNIX hosts on a trusted LAN into a singular Bourne shell multi-computer on which shell scripts are run concurrently. The service abstracts hosts into what appears to be shell process with a fixed number of threads or workers, to which work may be assigned and results received concurrently. It includes utilities that assign commands to workers in parallel and a command that initiates distributed barriers between workers for synchronization purposes. Environment variables can be set on a per-host basis to implement locking mechanisms like semaphores or ticket algorithms. Daemons can delegate work to one another as needed.
Bviplus is a console ncurses based binary file editor (hex editor) with Vim-like keys and features. It can quickly open/edit/save very large files (> 2GiB). It can perform regexp-like pattern searches in hex or ASCII windows. It features search highlighting, multiple undo/redo, a tabbed multiple file interface, visual selection, cut and paste (which works between files as well), blob coloring, and more. It can run external programs on selected data, supporting any program that reads stdin and writes stdout. It has few dependencies for easy portability.
libjc is a framework for event-driven development in C. Programs that use it can perform an arbitrary number of operations simultaneously and in the background, and later wait for some or all of them to complete. The source package includes the core library along with a few objects, each of which is able to perform a set of related operations. This framework consumes significantly less memory than standard libraries, and it scales well to multiprocessor systems.
PacketDam is a cost-effective software solution against DDoS. It runs on off-the-shelf hardware and fits any budget or deployment scenario. If you are an Internet service provider or a content distribution network, if you offer hosting services, or if you are an academic institution, PacketDam may be just what you need to keep unwanted traffic outside your network.
Concurrency Kit provides a plethora of concurrency primitives and lock-less and lock-free data structures designed to aid in the design and implementation of high performance scalable concurrent systems. It was designed to minimize dependencies on operating system-specific interfaces, and most of the interface relies only on a strict subset of the standard library and more popular compiler extensions.
Safelock is a file-based locking primitive that provides mutual exclusion between unrelated processes and threads. It offers advantages over POSIX and BSD file locks such as: compatibility with multi-threaded applications, support for lock attempt timeouts, detection of crashed lock holders, and detailed lock status (PID, lock age, custom data).
