What it does

I've been working on a new Clojure implementation targeting Chez Scheme , and it's now at a point where I'd like to share it more broadly in hopes that it might be useful to others. This post will explain the rationale behind the project, its current status, and why it may be of interest. My main goal was to make a drop-in replacement for JVM Clojure which had a fast startup and a light memory footprint. If you look under the hood of Jolt you'll quickly see why Chez Scheme is a great choice for hosting Clojure. Since both languages share the same Lisp roots, the core semantics of Clojure map seamlessly to Scheme, avoiding the impedance mismatch associated with forcing functional paradigms…from yogthos.net

    I 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…

    Hey HN, I wrote a short book about the fundamental aspects of Clojure. The target audience is programmers with at least minimal experience who want to learn how to express solutions in Clojure (and perhaps in LISP, generally). If the price is a bit too steep for you, send me an email (address in bio), and I'll provide a discount coupon. If you can't afford it all, and believe the material may help you for studying or interview preparations, I can send you a free copy.

    I replaced a $120k bowling center system with $1,600 in ESP32s▲2,935

    I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

    Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)▲1,033

    Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

  • Getting GLM 5.2 running on my slow computer▲937

    A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

  • OpenSEO▲928

    Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
