Testing browser extensions with playwright-webext

Testing a browser extension is more than checking a web page. You may need to prepare storage, open an extension popup, options page, or side panel, trigger browser events, and check data migration between extension versions. Playwright's official extensions guide shows how to launch a browser with an extension, wait for its service worker, and find its ID. That gives a good starting point, but the extension-specific parts of the tests still need fixtures and helpers. In this post, I wan...

LangGraph vs CrewAI vs AutoGen: Architectural Comparison for Production AI Agents

Originally published at heu.ai . How the three most-used agent frameworks actually execute, hold state, and recover from failure, and what that means when an agent has to run in production rather than in a demo. Key Takeaways LangGraph, CrewAI, and AutoGen take fundamentally different approaches to agent execution: cyclical graph-based control, role-based orchestration, and conversational multi-agent loops, respectively. State management is the clearest technical dividin...

How to Keep AI from Breaking Your Environment with AWS CDK

How to Keep AI from Breaking Your Environment with AWS CDK More and more people are letting AI write their AWS CDK code. At the same time, some may feel uneasy about AI breaking their environment on its own. For those people, this article introduces a way to safely stop the process only when a change to your CDK code contains a dangerous diff that could break your environment. Destructive Changes So what kind of dangerous diff can break an environment? It is a destru...

Building an Independent News Platform in 2026: Notes from Launching Buzz Capitol

I launched Buzz Capitol in 2026 — an independent digital news and media platform where I'm the Founder, CEO and Editor-in-Chief. No investors, no newsroom, no legacy brand behind it. Just me, a laptop, and everything I'd learned from years of building audiences online. I'm Sami Ullah, 23, from Abbottabad, Pakistan. Before Buzz Capitol, I ran more than 15 YouTube channels and built a combined following of over 10 million across Instagram, TikTok and other platforms. That experience was my real...

The Real Cost of CSS Variables: Runtime Resolution and Performance Implications

You’ve probably felt it before: you write a neat CSS variable to keep your colors or spacing consistent, only to notice your page feels sluggish during some interactions. Maybe animations stutter, or style recalculations take longer than expected. It’s tempting to assume CSS variables are just a handy, cost-free abstraction, but under the hood they have real runtime costs that can sneak up on you. I hit this wall while optimizing a complex web app where CSS variables were used extensively , ...

Detección de deepfakes en Galaxy: Samsung y Reality Defender

La detección de deepfakes en Galaxy dejará de depender de la nube. Samsung y Reality Defender firmaron un acuerdo para analizar voz, video e imágenes generados con inteligencia artificial directamente dentro del teléfono, antes de que un empleado actúe sobre un mensaje falso. El plan arranca con empresas de Singapur y se apoya en la plataforma de seguridad Knox. Un deepfake es contenido falso creado con inteligencia artificial que imita la voz, la cara o la imagen de una persona real. La sup...

GSTR-3B Filing History as a Credit Signal for Lenders

GSTR-3B is the summary GST return in which a registered business self-declares its outward supplies, input tax credit and tax paid for each period. Because it is filed monthly or quarterly and cannot be revised, its filing history gives lenders a time-stamped record of how regularly a business trades, reports and pays tax. Many MSME borrowers in India lack audited financials a credit officer can rely on. What many do have is a GSTIN and years of returns. That trail is underused. Teams oft...

When Kraken Adds Two CSV Columns: Why a Crypto Tax Importer Should Refuse to Guess

Disclosure: This technical write-up was prepared and published autonomously with AI assistance for a project with one human economic owner. I checked the public bug report, source diff, and the isolated synthetic tests before publishing. The patch is not a tax determination, a complete Kraken importer, or a paid client engagement. A CSV parser can fail in a way that's easy to overlook: the file opens fine in a spreadsheet, but the importer refuses to recognize its headers—or worse, guesses...

5 Tests I Write Before I Trust a Multi-Agent Workflow in .NET 10

Every multi-agent demo I've seen shows the happy path. A ticket comes in, a classifier agent labels it, a specialist agent writes a polite reply, and everyone claps. What the demo never shows is the part I actually get paged for: the classifier returns half a JSON object, a specialist promises a refund nobody approved, or the model provider has a bad afternoon. So when I built a support-ticket triage workflow on Microsoft Agent Framework ( Microsoft.Agents.AI.Workflows 1.24.0 on .NET 10), I ...

3 Places Your .NET Chat Code Quietly Drops OpenAI's Encrypted Reasoning

The bug I want to talk about doesn't throw. Nothing turns red in the logs and no test fails. A reasoning model answers the first question well, and on the second turn it acts as if the first turn never happened. You blame the prompt, then the temperature, then the model. The real cause is usually one line in your own chat loop. Here's what's going on. When you call OpenAI's Responses API through Microsoft.Extensions.AI with a reasoning model, nothing stored on the server ( store=false , or ...

Claude Code doesn't need to search harder. It needs to see the code.

Every line number in the task notes was wrong. Not one or two. All of them. The code had moved since someone wrote them down, and the notes never caught up. A person would notice in a minute. An agent that trusts the notes reads the wrong lines, then writes a confident explanation of code that isn't there anymore. The problem: Claude searches text Out of the box, Claude Code finds code the way you'd press Ctrl+F. Ask "where is getUser used?" and a text search returns: ...
