Julius, a New Lisp Implementation
This is a new and very preliminary Lisp implementation that is based on Common Lisp. The main goals are to minimize external dependencies. Currently only sbcl is supported. The only other dependency is on Quicklisp, which should strictly be necessary only for testing.
Julius, a New Lisp Implementation launched on May 3, 2026 with 14 votes, #1,027 of 20,538 launches that month and more than 90% of that year's launches.
In plain words
Julius is a preliminary Lisp implementation based on Common Lisp designed for developers seeking minimal external dependencies. It currently runs on SBCL, with Quicklisp required only for testing purposes. The project prioritizes simplicity and self-containment, making it suitable for those who want a lightweight Lisp environment without heavy dependency chains.

A Common Lisp implementation in development, supports ASDF2025 · savannah.nongnu.org · ▲96Implementation of the standard is still not complete, but breakpoints and stepping work quite well! It also has some support for watchpoints, that no implementation has. Now it ships with ASDF and is capable of loading systems! Let me know if you like it. Support on Patreon or Liberapay is much appreciated
- IWI wrote a technical history book on LispFeb 2026 · berksoft.ca · ▲252
The book page links to a blog post that explains how I got about it (and has a link to sample content), but the TL&DR is that I could not find a lot of books that were on "our" history _and_ were larded with technical details. So I set about writing one, and some five years later I'm happy to share the result. I think it's one of the few "computer history" books that has tons of code, but correct me if I'm wrong (I wrote this both to tell a story and to learn :-)). My favorite languages are Smalltalk and Lisp, but as an Emacs user, I've been using the latter for much longer and for my…

Interactive Common Lisp: An Enhanced REPLDec 2025 · github.com · ▲101I created this because sometimes I want more than rlwrap but less than emacs. icl aims to hit that middle sweet spot. It's a terminal application with context-aware auto-complete, an interactive object inspector, auto-indentation, syntax colouring, persistent history, and much more. It uses sly to communicate with the child lisp process and aims to be compatible with any sly-supporting implementation. I hope others find it useful!

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Parallel agents, diff reviewer, and multi-model comparisons
Dev tools · May 2026 · kilo.ai



Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
