GameMode
Optimise Linux system performance on demand
GameMode is a daemon/lib combo for Linux that allows games to request a set of optimizations be temporarily applied to the host OS and/or a game process. GameMode was designed primarily as a stop-gap solution to problems with the Intel and AMD CPU power save or on-demand governors but is now host to a range of optimization features and configurations. -

MiniLisp
A readable lisp in less than 1k lines of C
MiniLisp is a compact Lisp interpreter implemented in fewer than one thousand lines of C, designed to demonstrate the core principles of Lisp and interpreter design in a highly readable format. The interpreter evaluates expressions in a traditional read-eval-print loop, allowing users to input Lisp code and immediately see the results. Despite its small size, it supports a wide range of language features, including integers, symbols, lists, closures, macros, and garbage collection. The project emphasizes clarity and educational value, with well-commented code that explains how each feature is implemented. It includes support for lexical scoping, user-defined functions, and a macro system, enabling users to explore advanced Lisp concepts. The interpreter also implements a copying garbage collector, demonstrating memory management techniques in a simple context. It is designed to run on Unix-like systems and includes a test suite for validation. -

ProcMon for Linux
A Linux version of the Procmon Sysinternals tool
ProcMon-for-Linux by Microsoft is an open-source port of the legendary Windows Sysinternals Process Monitor, adapted for Linux environments. It captures and displays real-time syscall activities—alongside process/thread details—in an interactive terminal interface. With filtering capabilities, full thread stack capture, logging to SQLite, and event replay, it offers powerful visibility into system behavior. Currently distributed as a preview release (up to v2.0 on Linux), it supports Ubuntu 18.04 kernels 4.18–5.3 with plans to expand compatibility across more distributions. -

ccls
C/C++/ObjC language server supporting cross references & hierarchies
C/C++/ObjC language server supporting cross-references, hierarchies, completion, and semantic highlighting. It has a global view of the code base and supports a lot of cross-reference features, see wiki/FAQ. It starts indexing the whole project (including subprojects if exist) parallelly when you open the first file, while the main thread can serve requests before the indexing is complete. Saving files will incrementally update the index. Hierarchies, call (caller/callee) hierarchy, inheritance (base/derived) hierarchy, member hierarchy. Symbol rename. Document symbols and approximate search of workspace symbol. Hover information. Diagnostics and code actions (clang FixIts). Semantic highlighting and preprocessor skipped regions. -

libctru
Homebrew development library for Nintendo 3DS/Horizon OS user mode
Library for writing user mode ARM11 code for the 3DS (CTR) This library aims to provide the foundations necessary to write 3DS Homebrew, and straightforwardly access the different functionalities provided by the 3DS operating system. It is not meant to provide higher-level functions; to put things in perspective, the purpose of libctru would be to sit between the OS and a possible port of SDL rather than replace it. libctru is just a library and needs a toolchain to function. devkitARM (created by devkitPro) is the officially supported ARM cross-compiling toolchain, which provides the framework necessary to supply a usable POSIX-like environment, with working C and C++ standard libraries; as well as the tools required to compile homebrew in the 3DSX format, and assemble GPU shaders. The use of other ARM toolchains is severely discouraged. -

Dopus5 – Directory Opus 5 (Amiga)
Dopus5 for all Amiga platforms (AmigaOS3, AmigaOS4, MorphOS and AROS)
Dopus5 (short for Directory Opus 5) is a well-known Workbench clone for AmigaOS-based computer systems. It features file manager functionality and has been a popular Amiga software title for many years. After acquiring the sources from the original authors (GPSoft – http://www.gpsoft.com.au/) this project was started to coordinate the porting of the sources to all modern Amigaoid platforms like AmigaOS4, MorphOS, AROS as well as updating it for the original AmigaOS3 platform. The nightly builds of dopus5 disabled at moment, but you can get "latest commit" ones from djbase's mirror: http://dopus5.amigaworld.de/ -

CacheGuard Gateway
CacheGuard Gateway is a UTM, a WAF, and a QoS management appliance.
CacheGuard Gateway is a free and open-source Unified Threat Management (UTM) solution, a Web Application Firewall (WAF), and a Quality of Service (QoS) platform designed to optimize WAN traffic. To obtain a CacheGuard Gateway appliance, download CacheGuard-OS and install it on the bare-metal or virtual machine of your choice. It’s that simple and completely free. The UTM includes a firewall, web antivirus, VPN server, and a URL-filtering and SSL-inspection web proxy. The WAF operates in conjunction with a reverse proxy, web application load balancer, and SSL offloader, and is capable of blocking malicious requests as well as traffic from IP addresses with poor reputations. The QoS manager enables traffic shaping to prioritize critical network flows, load balance multiple WAN links, and cache web traffic. -

BrazilFW Firewall and Router
A powerful network security tool, easy, safe and totally free.
BrazilFW is a mini Linux distribution designed to be used as a Firewall and Router that runs easily on older computers. An old PC running BrazilFW is much more powerful and efficient than commercial software for routing in offices and residences running on a "powerful" computer. BrazilFW is based on Coyote Linux, which was designed by Joshua Jackson who discontinued Coyote Linux in version 2.24 in August 2005. In that same month comes on the scene BrazilFW Firewall and Router (BFW) with version 2.24, which is led by "Claudio" and "Marcelo - Brazil", running only on floppy disks, and being 2.30.1 the last version with this support . The following versions, as well having automatic detection of network cards, only run on large capacity media, such as hard disk (HD). Versions in Development: * 2.33.x: Uses kernel 2.4.x and is developed by Marcinho Samurai. * 3.x: Uses kernel 4.x and is developed by WoshMan -
