ARIS
Lightweight Markdown-only skills for autonomous ML research
ARIS is an experimental automation framework that leverages AI coding agents to perform continuous research and development tasks autonomously, even without active user supervision. The system is designed to run iterative cycles of research, coding, testing, and refinement, effectively simulating a “sleep mode” where productive work continues in the background. It integrates with AI tools such as Claude Code to generate solutions, analyze results, and improve outputs over time. The project emphasizes long-running workflows that can explore problem spaces more deeply than manual intervention would typically allow. It also highlights the potential of autonomous agents to handle repetitive or exploratory tasks that would otherwise require significant human effort. The framework is particularly relevant for developers interested in automated experimentation, continuous learning systems, and AI-driven productivity. -

An extensible emacs dashboard
An extensible emacs startup screen showing you what’s most important. The widget “projects”, which shows a list of recent projects, is not enabled by default since it depends on packages that might not be available.

MultiMarkdown
Expanded perl version of John Gruber's original Markdown
MultiMarkdown is an expanded Perl-based implementation of John Gruber’s original Markdown language. It builds on the simplicity of Markdown’s text-to-HTML conversion by adding support for features that make it more useful for technical writing, academic publishing, and complex documents. The project allows users to write documents in a human-readable plain text format and convert them into structured HTML or other formats. Unlike standard Markdown, MultiMarkdown adds capabilities for tables, footnotes, citations, cross-references, and metadata, making it especially valuable for longer and more detailed documents. Its design philosophy is to maintain Markdown’s ease of use while expanding its ability to handle professional publishing needs. Although this version is no longer under active development since MultiMarkdown 3, it remains a reference implementation for earlier enhancements to Markdown. -

SLIME
The Superior Lisp Interaction Mode for Emacs
SLIME is a Emacs mode for Common Lisp development. Inspired by existing systems such Emacs Lisp and ILISP, we are working to create an environment for hacking Common Lisp in. SLIME extends Emacs with support for interactive programming in Common Lisp. The features are centered around slime mode, an Emacs minor mode that complements the standard lisp mode. While lisp-mode supports editing Lisp source files, slime-mode adds support for interacting with a running Common Lisp process for compilation, debugging, documentation lookup, and so on. The Read-Eval-Print Loop ("top-level") is written in Emacs Lisp for tighter integration with Emacs. The REPL also has builtin "shortcut" commands similar to those of the McCLIM listener. SLIME is able to take compiler messages and annotate them directly into source buffers. -

buku
Personal mini-web in text
buku is a powerful bookmark manager and a personal textual mini-web. For those who prefer the GUI, bukuserver exposes a browsable front-end on a local web host server. When I started writing it, I couldn't find a flexible command-line solution with a private, portable, merge-able database along with seamless GUI integration. Hence, buku. buku can import bookmarks from the browser(s) or fetch the title, tags and description of a URL from the web. Use your favorite editor to add, compose and update bookmarks. Search bookmarks instantly with multiple search options, including regex and a deep scan mode (handy with URLs). It can look up broken links on Wayback Machine. There's an Easter Egg to revisit random bookmarks. There's no tracking, hidden history, obsolete records, usage analytics or homing. To get started right away, jump to the Quickstart section. buku has one of the best documentation around. The man page comes with examples. -

dap-mode
Emacs Debug Adapter Protocol
Emacs client/library for Debug Adapter Protocol is a wire protocol for communication between client and Debug Server. It's similar to the LSP but provides integration with debug server. The API considered unstable until 1.0 release is out. It is tested against Java, Python, Ruby, Elixir and LLDB (C/C++/Objective-C/Swift). The main entry points are dap-debug and dap-debug-edit-template. The first one asks for a registered debug template and starts the configuration using the default values for that particular configuration. The latter creates a debug template which could be customized before running. dap-debug-edit-template will prepare a template declaration inside a temporary buffer. You should execute this code using C-M-x for the changes to apply. You should also copy this code into your Emacs configuration if you wish to make it persistent.
