nuster
A high performance HTTP proxy cache server and RESTful NoSQL cache
nuster is a high-performance HTTP proxy cache server and RESTful NoSQL cache server based on HAProxy. It is 100% compatible with HAProxy and takes full advantage of the ACL functionality of HAProxy to provide a fine-grained caching policy based on the content of request, response or server status. nuster can be used as an HTTP/TCP load balancer just like HAProxy. nuster can also be used as a RESTful NoSQL cache server, using HTTP POST/GET/DELETE to set/get/delete Key/Value objects. It can be used as an internal NoSQL cache that sits between your application and a database like Memcached or Redis as well as a user-facing NoSQL cache that sits between the end-user and your application. It supports headers, and cookies, so you can store per-user data to the same endpoint. -

pesconvert
Brother PES file converter
pesconvert is a command-line utility for converting Brother PES embroidery files into more accessible formats for viewing or further processing. It parses stitch commands, color changes, and frame boundaries from the binary PES structure and reconstructs the path of the needle across the canvas. The tool emits vector-friendly output so you can inspect or scale designs without losing detail, making it handy for previewing patterns or preparing them for other software. Because the PES format encodes jumps, trims, and thread changes, the converter normalizes these events into a clean sequence of segments. The implementation favors clarity so hobbyists can understand and extend it for their own machine workflows. It’s a practical bridge between proprietary embroidery design files and open tooling. -

pg_auto_failover
Postgres extension and service for automated failover
pg_auto_failover is a PostgreSQL extension and management tool for automated high availability. It handles health checks, failover, and monitoring without requiring third-party tools or complex configuration. Designed by the Citus Data team at Microsoft, it's ideal for developers and ops teams wanting reliable HA with minimal effort. -

pglogical
Logical Replication extension for PostgreSQL
pglogical is an advanced logical replication extension for PostgreSQL that allows selective replication of data between databases. Unlike physical replication, it enables fine-grained control of which tables or changes to replicate. It’s well-suited for multi-master setups, version upgrades, and real-time data distribution across environments. -

pulseaudio-modules-bt
PulseAudio bluetooth modules
Adds Sony LDAC, aptX, aptX HD, AAC codecs (A2DP Audio) support to PulseAudio on Linux. This repo is a fork of PulseAudio Bluetooth modules. Added support for manual (expert) configuration for SBC codec parameters. You can use the parameters to override and fine-tune the default SBC codec config and manually setup configurations like SBC XQ, or Dual Channel HD mode. More info about SBC configuration options can be found at LineageOS documentation. Also, there is an interactive calculator and unofficial device compatibility list that may help you to select proper values. -

qengine
Retro game engine for creating games like it's 1997
qengine is a cross-platform retro game engine. It is aimed at nostalgic game developers that miss simple times and enjoy creating games like it's 1997. The software renderer provides the aesthetic that we all love and the engine limitations exist to make your creativity shine. The engine is a fork of the Quake II codebase that focuses on serving as a base for standalone games. Unlike other ports, it does not aim at being compatible with mods or the base Quake II game. In fact, many features were removed to reduce the complexity of the codebase and make the process of creating new games on top of the engine easier and faster. Removal of overly specific gameplay code, such as enemies and weapons. Merge of modules into a single package. No more DLLs, just a single executable for client and another for server. qengine stands on the shoulders of giants from the Quake II community. The code is built upon Yamagi Quake II, which itself contains code from other amazing projects. -

raygui
A simple and easy-to-use immediate-mode gui library
raygui is a lightweight, easy-to-use immediate-mode graphical user interface (GUI) library designed primarily to work alongside the raylib graphics programming library, though it can be adapted for other engines. It provides an API inspired by immediate-mode GUI paradigms, similar to Unity’s IMGUI, which allows developers to create buttons, sliders, text boxes, panels, and other controls without managing retained widget states. Because the library is distributed as a single header file containing both declarations and implementations, including it in a project is simple and doesn’t require complex build configurations. raygui supports a wide range of controls and customization options for colors, fonts, and layout metrics, and also includes a built-in set of 1-bit icons that can be embedded into controls. It’s intended for tools development, rapid GUIs for editors or debug interfaces, and simple applications that need basic UI without heavy frameworks. -

test-tlb
Stupid memory latency and TLB tester
test-tlb is a tiny C microbenchmark that explores the performance characteristics of memory access patterns with respect to the CPU’s Translation Lookaside Buffer (TLB) and caches. It walks arrays using different strides and working-set sizes so you can observe when access patterns overflow cache or TLB capacity. By timing tight loops and varying parameters, the program reveals step-changes in latency that map to cache lines, page sizes, and TLB coverage. It is intentionally minimal so you can modify page sizes, strides, or pointer-chasing strategies to run experiments on different machines and kernels. The code is useful for teaching, hardware bring-up, or validating assumptions about huge pages and NUMA placement. Rather than providing a plotting framework, it prints timings that you can collect and graph with external tools to visualize cache/TLB boundaries. -

tslib
Touchscreen access library
C library for filtering touchscreen events. tslib consists of the library libts and tools that help you calibrate and use it in your environment. tslib runs on various hardware architectures and operating systems, including GNU/Linux, FreeBSD, or Android/Linux. Apart from building the latest tarball release, running ./configure, make, and make install, tslib is available from distributors like Arch Linux / Arch Linux ARM, Buildroot, Debian / Ubuntu, Fedora, or OpenSUSE and their package management. -

wal2json
JSON output plugin for changeset extraction
wal2json is an output plugin for logical decoding. It means that the plugin have access to tuples produced by INSERT and UPDATE. Also, UPDATE/DELETE old row versions can be accessed depending on the configured replica identity. Changes can be consumed using the streaming protocol (logical replication slots) or by a special SQL API. format version 1 produces a JSON object per transaction. All of the new/old tuples are available in the JSON object. Also, there are options to include properties such as transaction timestamp, schema-qualified, data types, and transaction ids. format version 2 produces a JSON object per tuple. Optional JSON object for beginning and end of transaction. Also, there are a variety of options to include properties. -

The Endless Dungeons
A free random dungeon game RPG (Roguelike)
The Endless Dungeons is an 8-bit style random dungeon game consisting of 10 character classes, hundreds of monster types, and 99 randomly generated dungeon levels. You must level your character from 1 to 99, collect items and equipment to make him or her more powerful, and finally confront the boss of the game, Xantos, on the 99th floor of the dungeon. Don't forget to download the manual if you want more info: http://sourceforge.net/projects/endlessdungeons/files/The%20Endless%20Dungeons.pdf/download There is also an FAQ on the forums here: https://sourceforge.net/p/endlessdungeons/discussion/general/thread/6ba973f6/ This game differs from a lot of other roguelikes in that it's largely GUI- and menu based (similar to old console RPGs) and has turn-based battles.
