Erlang/OTP
Build massively scalable soft real-time systems
Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability. Some of its uses are in telecoms, banking, e-commerce, computer telephony and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance. OTP is set of Erlang libraries and design principles providing middle-ware to develop these systems. It includes its own distributed database, applications to interface towards other languages, debugging and release handling tools. Erlang/OTP is available as pre-built binary packages by most OS package managers. You can use Kerl, a script that lets you easily build Erlang with a few commands. We take security bugs in Erlang/OTP seriously. The Erlang distribution includes a step-by-step getting started guide. -

Zotonic
The Erlang Web Framework & CMS
Zotonic is the content management system and framework for semantic data and high-connectivity websites. Your data outlives your website. Grow your data and share your data. The Zotonic content management system excels in managing structured data from multiple sources. It brings structure to your documents and makes semantic data manageable for normal humans. Real-time connectivity is deeply integrated using the Internet of Things publish/subscribe protocol MQTT. You can rapidly develop CMS-based sites on top of Zotonic. If you need more flexibility, you can customize all aspects of Zotonic. The included web server means can start working with Zotonic right away, without the need for installing Apache or Nginx separately. Zotonic is structured into modules. Each module offers a specific piece of functionality; the CMS is itself a module. There are modules for access control, social media integration, TLS, video embeds and much more. -

30 Days of Elixir
A walk through the Elixir language in 30 exercises
30-days-of-elixir is an educational repository created by Josh Adams (seven1m) designed to teach the fundamentals of the Elixir programming language through a structured, daily learning approach. The project provides a series of exercises and examples meant to guide learners from the basics of Elixir syntax to more advanced functional programming concepts. Each day introduces new material in a concise and practical format, encouraging hands-on experimentation and gradual mastery of the language. The content covers essential topics such as pattern matching, recursion, data structures, processes, and message passing—core principles that define Elixir’s design. This incremental learning format allows developers to build confidence and understanding while maintaining consistent progress. As one of the early and influential resources in the Elixir community, 30-days-of-elixir remains a valuable guide for self-learners and newcomers to the functional programming paradigm. -

Popcorn
Running Elixir in the browser
Popcorn is an experimental library that allows Elixir code to run locally in the browser with JavaScript interoperability. It is intended for developers who want to explore client-side Elixir workflows without relying entirely on server-side execution. The project is still early and may introduce breaking changes, so it is best suited for experimentation, prototypes, and research rather than stable production use. Popcorn connects Elixir’s programming model with browser-based execution, opening the door for local interactive experiences and future LiveView-style ideas. It is useful for developers interested in WebAssembly, local-first interfaces, and alternative ways to build browser applications. Its main value is exploring what Elixir development can look like when part of the application logic runs directly on the client. -

Vundle.vim
Vundle, the plug-in manager for Vim
Vundle.vim is one of the original plugin managers for Vim, designed to make discovering, installing, and updating plugins as simple as editing your vimrc. It uses a declarative, Git-backed approach where each plugin is listed as a line, and Vundle takes care of cloning and wiring it in. The interactive interface supports searching for plugins from inside Vim, which lowers the barrier to exploring the ecosystem. Its core model emphasizes repeatability: your vimrc is the source of truth, making your setup easy to share across machines or teams. Vundle also provides commands to clean out unused plugins and to update all dependencies with a single keystroke. While newer managers exist, Vundle remains a straightforward, battle-tested choice that many guides and dotfiles still rely on. -
