    Show HN: Snarl – Fast Shacl Validator

    SNARL: A SHACL Core validator written in SLOP. Compiles to C. I created a rust crate for this as well using FFI, as I'm integrating this into a larger Rust project.

    Well, the crazy thing I'm working on (100% self-funded thus far): https://trivyn.io . The main idea is moving most of the reasoning to the symbolic layer so the "neuro" piece can b…

    True. Sometimes I'll run front-end and backend work in two different claude instances, but always on the same project/product. I'll have "reviewer" instances in opencode using a di…

    Show HN: Growl Owl 2 RL Reasoner

    GROWL is an OWL 2 RL reasoner I've made using a programming language I've been working on that emphasizes contracts (called SLOP). Blog post on GROWL: https://jamesadam.me/blog/int…

    Yea, my issue with Opus 4.5 is it's the first model that's good enough that I'm starting to feel myself slip into laziness. I catch myself reviewing its output less rigorously than…

    I've been getting some good results from sqlite-vec on my current project. I need to look at geospatial extensions next.

    I've found most LLMs I've tried generate better code in typed, procedural languages than they do in something like Clojure. From the perspective of a primarily backend dev who know…

    Yea, my house is on Starlink... so at the moment I'm working in the back room of my wife's restaurant (she has cable internet). At least I get free coffee here.

    Most US citizens applying for software engineering jobs can't even get a response to their resume, and then I read stories like this.

    I worked in defense contracting for most of my ~20 year career up until a few months ago. So I'm experiencing this culture shock the other way around. Being the oldest person on a …

    It's not just software -- My wife owns a restaurant. Operating a restaurant you quickly learn the sad fact that quality is just not that important to your success. We're still tryi…

    I simply can't get interviews now (I've had two so far over the last 6 weeks). A few years ago I would be getting absolutely slammed with interview requests to the point I'd have t…

    I was recently laid off from a startup and I've never seen the job market this dead. And I was unemployed for a few months back in 2008.

    Never used monads with Clojure (the only Lisp I've done "serious" work in). Haskell introduced them to me, but I've never done anything large with Haskell (no jobs!). Scala, howeve…

    Never experienced the dive-and-save myself. Usually a wince and a sigh, followed by "oh... when's your last day?" Your first line supervisor is upset, but resigned that he's powerl…

    Absolutely. I was stationed in Germany for 3 years while I was in the Army. You could be in the left lane of the Autobahn, doing 90+ passing a truck, and suddenly a Ferrari that wa…
