Iosevka
Versatile typeface for code, from code
Iosevka is an open-source, sans-serif + slab-serif, monospace + quasi‑proportional typeface family, designed for writing code, using in terminals, and preparing technical documents. The Iosevka’s monospace family is provided in a slender outfit by default: glyphs are exactly 1/2em wide. Compared to the competitors, you could fit more columns within the same screen width. Iosevka provides two widths, Normal and Extended. If you prefer more breeze between the character, choose Extended and enjoy. Terminal emulators have a stricter compatibility requirements for fonts. Therefore, Iosevka and Iosevka Slab all contain two specialized families, Term and Fixed, targeting terminal users. In these families, the symbols will be narrower to follow terminals’ ideology of column count. In the Fixed families, the ligation will be disabled to ensure better compatibility in certain environments. -

Jupyter Notebook
Jupyter Interactive Notebook
The notebook extends the console-based approach to interactive computing in a qualitatively new direction, providing a web-based application suitable for capturing the whole computation process: developing, documenting, and executing code, as well as communicating the results. The Jupyter notebook combines two components. A web application, which is a browser-based tool for interactive authoring of documents which combine explanatory text, mathematics, computations and their rich media output. And Notebook documents, which are a representation of all content visible in the web application, including inputs and outputs of the computations, explanatory text, mathematics, images, and rich media representations of objects. Notebook documents contain the inputs and outputs of a interactive session as well as additional text that accompanies the code but is not meant for execution. -

Hacker Scripts
Based on a true story
Hacker Scripts is a cheeky collection of small automation scripts and language ports collected under the tagline “Based on a true story.” The repository gathers playful utilities (originally shell and Ruby scripts) that automate short, real-world tasks — for example, sending a quick “late at work” text when SSH sessions are active, firing off an automated “I’m sick / working from home” email on certain mornings, or even talking to a networked coffee machine to start brewing at precisely the right moment. The README explains the origin story and highlights several canonical scripts and provides usage notes such as required environment variables and cron examples for scheduling. Contributors have provided implementations and ports in many languages and folders (shell, Ruby, Python, Node, Perl, PowerShell, Go, Java, etc.), and the project explicitly welcomes pull requests that add additional language implementations. -

Scrcpy GUI
A simple & beautiful GUI application for scrcpy
Scrcpy was created by the team behind the popular Android emulator Genymotion, but it is not an Android emulator itself, it displays and controls Android devices connected via USB or TCP/IP, it does not require any root access. It works with GNU/Linux, Windows, and MacOS. Scrcpy works by running a server on your Android device, and the desktop application communicates using USB (or using ADB tunneling wireless). The server streams the H.264 video of the device screen. The client decodes the video frames and displays them. The client captures input (keyboard and mouse) events, sends them to the server, and the server injects them into the device. If you want to see your Android screen interact with the app or content on your desktop, record your phone screen or perform other basic tasks, then Scrcpy is a good choice. In short, Scrcpy is an excellent way to easily view your Android screen on your computer and interact with it in real time. -

Selenium
Browser automation framework and ecosystem
Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well. If you want to create robust, browser-based regression automation suites and tests, scale and distribute scripts across many environments, then you want to use Selenium WebDriver, a collection of language specific bindings to drive a browser - the way it is meant to be driven. If you want to create quick bug reproduction scripts, create scripts to aid in automation-aided exploratory testing, then you want to use Selenium IDE; a Chrome and Firefox add-on that will do simple record-and-playback of interactions with the browser. If you want to scale by distributing and running tests on several machines and manage multiple environments from a central point. -

Fabric
Fabric is an open-source framework for augmenting humans using AI
Fabric is a command-line framework that turns a curated library of prompt “patterns” into reusable, automatable workflows for large language models. Instead of repeatedly crafting ad-hoc prompts, you pick a pattern (for research, summarization, brainstorming, code review, and more) and feed it inputs or files. The tool standardizes execution with configuration files and environment variables, enabling reproducible runs across different models and providers. Patterns can be customized with variables, chained into pipelines, and applied to entire directories, which helps scale editorial or analytical tasks. A growing catalog of community patterns serves as a knowledge base for effective prompt engineering in practical contexts. In short, Fabric makes LLM work predictable and scriptable, so teams can share methods rather than one-off prompts.
