Symbiote.js: superpowers for Web Components

The whole point of creating and adopting new libraries and frameworks is to solve problems that haven't been solved before — or to solve them more efficiently than existing solutions do. Today we'll start a conversation about the kind of problems Symbiote.js can solve — and do it far more simply and elegantly than other frameworks. Symbiote.js is a lightweight (~6 KB brotli) yet very powerful li...

ARO – A language where business logic reads like documentation

Per AutoModerator's request I hereby confirm that the whole purpose of this project is to be LLM-generated. I've been building ARO, a declarative programming language where every statement follows a single grammatical pattern: Action the Result preposition the Object. The idea is that business features should be readable by anyone — developers, PMs, compliance officers — without translation. Her...

Amazon Aurora DSQL: A Practical Guide to AWS's Distributed SQL Database

Architecture, features, Terraform setup, and real application code - April 2026 When AWS announced Aurora DSQL at re:Invent 2024, I was very interested.

Your structured outputs are probably less portable than you think

Structured outputs are less portable across LLM providers than they look. A schema change can seem harmless and still break one provider while passing another. I built Schema Gateway for that exact failure mode. What it does: compile one schema into provider-ready request shapes diff a baseline schema against a candidate schema lint for portability issues normalize payloads against a schema ...

Stop picking Cursor or Claude Code. Pay for both, you cheapskate.

Each week I see a new post asking "Cursor vs Claude Code — which do you choose?" And each week I keep on scrolling. The comparison is false, and deep down, you know it is. You're not making a choice between two competitors. You're making a choice between a hammer and a screwdriver, and then boasting that you only needed one. Why This Debate Exists Cursor was $20 a month (then it flipp...

I built a Laravel queue monitoring tool because I got tired of not knowing what my jobs actually do

At some point I realized I don’t really understand what’s going on with my queues. I mean, yeah: jobs are running workers are alive logs exist somewhere But if I try to answer simple questions: did this job actually do what it was supposed to do? or did it just “successfully complete”? where do things silently break? — I don’t really have good answers. The most annoying part — silent failu...

Level Up Your SQL: Subqueries & CTEs in the Real World

In the first SQL article, you met the basics: tables, data types, simple SELECTs, and filters. Now you’re ready for the point where “one query” quietly turns into “three nested queries and a headache.” This is where subqueries and Common Table Expressions (CTEs) earn their keep. They let you think in layers, express complex logic clearly, and avoid turning every report into a wall of SQL noise....

When Identity Breaks and Consent Arrives Late — Systems Still Run, But Signals Lose Meaning

Modern digital systems depend on signals to represent reality. But not all signals carry the same weight. Two signals, in particular, shape how systems interpret everything else: • identity • consent When these signals lose coherence, systems may continue to operate. But the meaning of what they observe begins to shift. Identity Is Not a Field — It Is Continuity Identity is often treated ...
