Set styles to words and create a Table of Contents in a click
KeyParaStocX (Keyword-based Paragraph Styling and Table of Contents eXtension) is a LibreOffice/Apache OpenOffice/OpenOffice.org extension that searches for the configured keywords in a text, changes their style and builds a Table of Contents for them, up to 7 levels. The keywords and their target styles can be configured by the users and used for every document they open. The extension integrates into Writer options and is independent of the operating system (should work on all). See the project homepage https://keyparastocx.sourceforge.io and the project Wiki in the menu above. -

CodeCopy
A browser extension that adds copy to clipboard buttons
CodeCopy is a browser extension that automatically adds “copy to clipboard” buttons to code blocks on popular documentation and Q&A sites. Its goal is to save developers time and frustration by making it a single click to copy example snippets, rather than manually selecting text and dealing with formatting issues. The extension detects code snippets on pages like GitHub, MDN, Gist, Stack Overflow, StackExchange, npm, Medium, and others, then overlays a small copy icon or button in the corner of each block. When a user clicks the button, codecopy uses the Clipboard API (or fallbacks) to copy the snippet to the clipboard with minimal visual noise or disruption. The repository provides the extension source, manifest, and build pipeline so that developers can contribute new site matchers or customize behavior. It is distributed under an MIT license and is available for multiple browsers, including Chrome, Firefox, and Opera. -

It integrates everything you need to search, organize and create academic literature in a single application: a digital library, reference manager, PDF and file manager, note taking and mind mapping. And the best: Docear works seemlessly with many existing tools like Mendeley, Microsoft Word, and Foxit Reader. Docear is free and open source, based on Freeplane, funded by the German Federal Ministry of Technology and developed by scientists from around the world, among others from OvGU, and the University of California, Berkeley. -

Journiv is a modern self-hosted private journaling platform that puts privacy and ownership at the forefront of personal reflection and mood tracking. Built as a complete journaling solution, Journiv includes prompt-based entries, mood logs, advanced search, media uploads, and intuitive analytics that let you explore patterns over time without relying on external cloud services. Because it runs on your own infrastructure (e.g., via Docker), all of your entries, moods, and memories stay under your direct control, making it a strong alternative to commercial journaling apps that collect data. The app is currently in beta and sees active development with improvements such as draft support, Markdown editing, and multimedia integration. It combines a clean, distraction-free interface with rich features like tagging, calendar views, and customizable journals, appealing to users who want both useful tools and full data sovereignty in their self-hosted ecosystems. -

Crossnote App
An interesting markdown note taking application
Crossnote is a Progressive Web Application built as a markdown-focused note reader and editor that works both offline and online, giving users a flexible platform for writing, organizing, and synchronizing notes. It distinguishes itself by supporting markdown editing with a rich set of formatting options, and by enabling integration with version control systems like git for syncing notebooks in arbitrary repositories. Users can add, edit, and manage markdown documents in the browser, and because it uses modern web technologies, the app caches itself and local data to work seamlessly when a network connection is unavailable. While the backend server that used to support hosted functionality is no longer maintained, the core frontend still offers a slick note-taking experience. Crossnote’s design takes inspiration from tools like markdown preview extensions and collaborative editors. -

Everpad
Evernote client well integrated with linux desktop
Everpad is a desktop integration layer that brings Evernote notes directly into the Linux environment, especially Ubuntu-based desktops. It runs a background service that syncs with your Evernote account and exposes your notes through an indicator applet and a Unity lens/search integration. The goal is to make Evernote feel like a native part of the desktop, so you can search, open, edit, and create notes without jumping to the web interface. It also supports note attachments, notebooks, and tags, so you can organize content in the same way you do on official Evernote clients. Because it plugs into the desktop search, you can surface notes alongside local files for faster retrieval. It was created to fill the gap for Linux users who didn’t have an official Evernote client but still wanted a smooth, native-like experience. -

MyPy
Optional static typing for Python
mypy is a static type checker for Python that analyzes source code without executing it, catching type errors early in development. It implements PEP 484-style type hints and supports gradual typing, allowing untyped or partially typed modules to coexist with statically typed code. The tool integrates with common editors and CI systems, and offers a daemon mode for fast, incremental checks across large codebases. Advanced configuration via mypy.ini or pyproject.toml enables per-module strictness, plugin hooks for popular libraries, and fine-grained control of inference and error reporting. Documentation covers everything from newcomer guides to strict mode recipes and release notes. The ecosystem includes typed stubs, third-party plugins, and broad community support that makes mypy a default choice for large Python projects. -

OpenShort.link
All-in-one, open-source, serverless URL shortener
OpenShortLink (OpenShort.link) is an open-source, serverless URL shortener designed to run entirely on Cloudflare’s edge stack, aiming to deliver fast redirects with minimal infrastructure management. It’s built for branded link ownership, letting you use your own domain for short links instead of relying on a third-party shortening service. Beyond basic shortening, it adds “smart routing” capabilities so a single short link can send different users to different destinations depending on factors like country or device type. The project also treats analytics as a first-class feature, capturing click activity and breaking it down by referrer, geography, device, browser, and campaign parameters to support marketing and operational reporting. For teams, it includes an account and permission model so multiple users can collaborate while keeping control over who can create, edit, or view links. -

polynote
A better notebook for Scala (and more)
Polynote is an innovative polyglot notebook environment that improves on traditional interactive computing tools by enabling multi-language notebooks where users can mix languages like Scala, Python, SQL, and more within a single document while sharing variables and definitions seamlessly across those languages. Designed to address shortcomings in classic notebook solutions, it blends features familiar from IDEs — such as smart autocomplete, parameter hints, and better runtime insights — with the flexibility of notebook workflows, enhancing both developer productivity and data exploration. Unlike many notebook environments that are tied to a single language kernel, Polynote tracks and manages state consistently across cells based on execution order and cell dependencies, which reduces hidden state and makes notebooks more reproducible and understandable. -
