Solving Riverpod’s Family Provider Cache Dilemma with Signals & mapSignal

Eliminating Stale Data Silos & Complex Invalidation Loops in Flutter Apps Key Takeaway: When separate family providers store parameterized network queries as isolated state silos, updating an entity in one subset creates stale data across others. By shifting to a normalized entity store (mapSignal) and reactive projections (computed), cache invalidations, duplicate network calls, a...

The Golden Rule of Payout Systems: Why "Pending" is Never a Failure

When you start working on modern payment infrastructure, moving money seems deceptively simple. A user initiates a payout. Your system calls a banking API. The bank responds with success or failure. You update your database accordingly. At least, that's how it looks on architecture diagrams. In reality, payout systems operate in a world of partial failures, delayed confirmations, network time...

What an AI Engineer job actually tests

An AI Engineer job posting almost never asks you to train a model. It asks for Python. Backend services. APIs. Deployment. Say you are two years into your career. You want the AI Engineer title, because that is where the hiring is right now. You open a listing. Under requirements you find things you already know: REST APIs, Postgres, a message queue. Then one line stops you: experience with LLM-b...

Designing Edit Operations for AI Agents

Four lessons from building IWE's block-editing language for LLM writers: state the blast radius, make identity a constraint, fail toward the recoverable mistake, and treat error messages as the documentation agents actually read. The problem: agents rewrite, and rewriting corrupts While benchmarking IWE as memory for AI agents (the full story is in 📝 The Benchmark That Built the Tools)...

Your New Eval Rule Is Untested Code Guarding Production

You wrote a new eval. It caught the failure you just saw in production. You shipped it as a gate. Congratulations — you now have a piece of untested code sitting on the hot path of every agent run, deciding what ships and what gets blocked. We treat agent evals as if writing them is the hard part. It isn't. The hard part is knowing your eval actually discriminates: that it goes red on the bad tra...

Tokenization in AI: What Is It, Why Is It Used, and How Does It Work?

Have you ever wondered how an AI model understands the sentence you type? For example, when you ask: «"How do I learn Python?"» An AI model doesn't directly process the entire sentence like a human does. Before the model can work with your text, the text usually goes through an important step called tokenization. In this post, we'll learn: What tokenization is Why AI models use tokenization...

The Hardest Bug to Find Was a False Positive.

The Benchmark Behind Proactive Scan On Tuesday we shipped Proactive Scan: one command that ranks your riskiest files and reads each with cross-file context, before anything crashes. Today we're publishing the benchmark behind it. All of it: the numbers, the methodology, the part where our first version cried wolf, and the kinds of bugs it still misses. The Result 28 test ca...

How Does AI Learn and Get Trained? A Simple Guide to Text, Image, and Video AI

Artificial Intelligence (AI) can write stories, answer questions, create realistic images, generate videos, write code, and much more. But how does AI actually learn? Does it think like a human? Does someone manually teach it every answer? The short answer is no. AI learns patterns from huge amounts of data using mathematical algorithms and powerful computers. In this article, we'll explore h...

How Is ""2" > "10"" "true" in JavaScript?

What is output of ""2">"10"" true or false At first glance, this looks completely wrong. We all know that: 2 > 10 is obviously: false Because 2 is smaller than 10. But what happens when we add quotation marks? "2" > "10" The result is: true 😱 Wait… how can 2 be greater than 10? The answer is simple: ""2"" and ""10"" are not numbers. They are strings. 🔢 Numbers vs. Strings ...

Gotcha: chasing a bug that was never in my code

This is a submission for DEV's Summer Bug Smash: Smash Stories powered by Sentry. The build was done. Themis Lex worked on my machine, and not in the "works if you squint" way. A court clerk enters their role, describes their workflow, picks a data sensitivity level, and gets back a PDF with two sections: where AI can safely support the work, and where it must never touch it.

Scrapped the entire mockup

SyncIEP was built for special needs educators, providers, and teachers. My co-founder taught special education for twelve years, and most of what we build comes out of arguments about how the work actually goes. The first screen I designed for it came from the perspective of workign in legal tech for 2 years, and that was wrong in a way that took a while to see. I built the initial mockup to loo...

Express vs Django: What I Learned Comparing the Two

As a software engineering student, I recently had to compare Express and Django for a web development course. Both are popular frameworks for building web apps, but they work pretty differently. Here's what I learned. What's the difference? Express is a framework for Node.js (JavaScript). It's very minimal — it doesn't force you to organize your project in a specific way. You basically...

Building Fluentic Style: Making Generated CSS Debuggable Again

This is part of my Building Fluentic Style series, where I’m writing down the design decisions, tradeoffs, and small surprises from building Fluentic Style. Generated CSS is not the problem. Generated CSS that cannot explain where it came from is the problem. That is one of the things I kept running into with styling tools over the years. A library can have a nice authoring API.

CISA rewrites the SBOM floor: hashes are required, and the scope now covers AI and SaaS

Five years after NTIA set the original floor, CISA has published the 2026 Minimum Elements for a Software Bill of Materials, replacing that baseline with a version that requires component hashes, adds license and generation-context fields, and applies the same minimum to open-source software, AI systems and software-as-a-service. Per the reporting on DevOps.com, the document was drafted with the N...
