FineTune
FineTune, a macOS menu bar app to control volume for each app
FineTune is a macOS menu bar application that gives users fine-grained control over system audio by allowing them to adjust volume levels for individual applications independently, route audio streams to different output devices, and apply personalized equalizer settings. It fills a gap in macOS audio control by providing more advanced routing and audio shaping capabilities than the default system controls, making it useful for power users, audio professionals, and anyone needing precise management of their sound environment. Through a clean, minimal interface accessible from the menu bar, FineTune lets users isolate and balance application volumes, assign specific outputs (like headphones versus speakers), and tweak equalization to enhance or tailor audio based on content or personal preference. Its integration into the OS workflow means that these adjustments persist across sessions and respect the user’s choices without requiring constant interaction with deeper system settings. -

WhiteSur GTK Theme
MacOS like theme for all gtk based desktops
WhiteSur-gtk-theme brings a macOS Big Sur–inspired look to Linux desktops by providing a polished GTK theme with light and dark variants, rounded shapes, and refined translucency. It includes assets and installer scripts to apply the theme across GTK applications and desktop shells that support GTK theming, aiming for a cohesive, high-contrast interface. The project pays attention to details like window controls, titlebars, selection states, and widget hover effects so apps feel consistent from toolkits to system settings. Configuration options typically allow tweaking accents and choosing variants that match different desktop environments and icon sets. Documentation guides users through installing prerequisites, applying the theme, and resolving common edge cases across distributions. For Linux users who prefer Apple’s visual style but want open platforms, WhiteSur offers a maintained, community-driven path to a modern, visually unified desktop. -

Thaw
Menu bar manager for macOS 26
Thaw is a macOS menu bar management app focused on hiding, showing, and organizing menu bar items, with the broader goal of being a versatile customization toolkit rather than a single-purpose hider. It is a fork of the Ice project created to keep the concept actively maintained, fix bugs, and stay compatible with the latest macOS releases, especially newer versions where menu bar behavior and APIs have changed. At its core, Thaw provides multiple ways to reveal hidden items (hover, click empty space, scroll or swipe) and can automatically rehide items to keep the menu bar clean without constant manual toggling. It also supports a dedicated “always-hidden” section, drag-and-drop arrangement of items, and options to display hidden items in a separate bar, which can be particularly useful on MacBooks with notches. -

erd
Translates a plain text description of a relational database schema
erd is a Haskell-based command-line tool that transforms a plain-text description of a relational database schema into a graphical entity-relationship diagram using common ER conventions. This utility takes a plain text description of entities, their attributes and the relationships between entities and produces a visual diagram modeling the description. The visualization is produced by using Dot with GraphViz. There are limited options for specifying color and font information. Also, erd can output graphs in a variety of formats, including but not limited to: pdf, svg, eps, png, jpg, plain text and dot. In case one wishes to have a statically linked erd as a result, this is possible to have by executing build-static_by-nix.sh: which requires the nix package manager to be installed on the building machine. NixOS itself is not a requirement. -

SkyWater PDK
Open source process design kit for usage with SkyWater Technology
The SkyWater PDK is the first broadly available open-source process design kit for a commercial-grade CMOS node, enabling researchers, startups, and students to design real ASICs without proprietary NDAs. It provides the essential artifacts for digital and analog flows: SPICE models, DRC/LVS rules, extraction decks, and technology files for open tools like Magic and KLayout. Standard-cell libraries and IO pads are included so digital designers can use open synthesis and place-and-route to reach a manufacturable GDS. Because the PDK is open, it becomes a common target for community reference designs, open tapeouts, and teaching curricula. Documentation and example flows show how to assemble complete toolchains, from RTL to sign-off, using open EDA components. The project effectively lowers the barrier to custom silicon, catalyzing an ecosystem around an accessible 130-nm process. -

Markdown
WeChat Markdown Editor
WeChat Markdown Editor | A highly concise WeChat Markdown editor, that supports Markdown syntax, color palette selection, multi-image upload, one-click document download, custom CSS style, one-click reset, and other features. Markdown documents are automatically rendered into WeChat graphics and text in real-time, so you no longer have to worry about the typesetting of WeChat articles! As long as you know the basic Markdown syntax, you can make a simple and beautiful WeChat graphic. Chrome browser is recommended for best results. In addition, for domestic (China) friends, accessing Gitee Pages will be relatively faster. The existing open-source WeChat Markdown editor has complicated styles and does not meet my personal aesthetic needs. When I use them for article typesetting, I often have to make some changes myself, which is time-consuming and labor-intensive, so I did secondary development. -

nightTab
A neutral new tab page accented with a chosen colour
A neutral new tab page accented with a chosen color. Customize the layout, style, background and bookmarks with nightTab. Make the browser start page dark (or light, or anything in between). Do not access user information. This means nightTab will not request browser permissions. Aim to make everything on the user interface, within reason, customizable. Aim to make the user experience easy while supporting the above. Keep nightTab open source. Sharing the look and feel of one Bookmark to another can be achieved when editing a single Bookmark. The Bookmark edit modal has three options to copy settings to other Bookmarks. These checkboxes can be found at the bottom of the Visual & Name, Layout and Theme tab. Development and testing is only conducted on Chrome and Firefox. The performance and reliability of nightTab on other browsers is out of the scope of this project. -

GitHub themes for Neovim
Github's Neovim themes
Github's Neovim themes. GitHub Theme's palettes and specs can be extended with your own values. This is useful for users who want to distinguish a spec value being used for multiple group definitions. GitHub Theme is a highly customizable and configurable color scheme. This does however come at the cost of complexity and execution time. GitHub Theme pre-computes the result of your configuration and saves the lua bytecode in a cache to be used on the next load. This significantly speeds up Github theme's execution time. Changes to your configuration will be re-computed and cached automatically. -
