The agents.txt IETF draft just expired. Here is what happens next.

The agents.txt IETF draft just expired this morning. If you deployed it, here is what to know. What agents.txt was agents.txt was a small spec inspired by robots.txt. The idea: drop a plain-text file at /.well-known/agents.txt declaring which automated agents your site permits, what content endpoints they should hit, and what capabilities you expose. It was the simplest possible answer...

AI-Generated PRs Lack Human Oversight, Leading to Poor Code Quality: Implementing Review Guidelines as Solution

Introduction: The Rise of AI-Generated Code and Its Challenges The integration of AI agents into software development has undeniably accelerated coding workflows. Engineers like the one in our source case now rely on agents for daily tasks, often bypassing manual coding entirely. However, this shift has introduced a critical friction point: AI-generated pull requests (PRs) frequently la...

How We Evaluate AI Agents Before Recommending Them to Clients

We get asked which AI agent platform to use at least a dozen times a week. Our answer is always the same: it depends on the workflow, not the tool. We have shipped over 350 products, many of them AI-powered, across 20+ industries. The evaluation framework below is what we actually use when a client comes to us with an agent build in scope. It is not a tool comparison. It is a decision framework b...

Understanding Defender AV Scans

Microsoft Defender Antivirus Defender is intended to operate silently in the background, without requiring any active attention from the user. Because Defender is included for free as a component of Windows, it doesn’t need to nag or otherwise bother the user for attention in an attempt to “prove its value”, unlike some antivirus products thatContinue reading "Understanding Defen...

12 Best Code Audit Tools in 2026 - Quality and Security

What is a code audit and why it matters A code audit is a systematic examination of source code to assess its quality, security posture, and compliance with standards. Unlike daily code reviews that focus on individual pull requests, a code audit takes a holistic view of the entire codebase - identifying systemic vulnerabilities, accumulated technical debt, architectural weaknesses, and...

Disk Has Space But Can't Create Files? (Linux Inode Exhaustion)

One of the most confusing Linux errors I've debugged: a production server reporting "No space left on device" while df -h clearly showed 50GB free. I lost an hour to it the first time. Here's what was actually going on. I turned scenarios like this into an interactive practice tool at scenar.site - you debug simulated servers by talking to an AI interviewer. More at the end.

How Forex Brokers Detect Latency Arbitrage in 2026: A Technical Breakdown

Latency arbitrage has existed as long as electronic forex trading has. The concept is straightforward: if you receive a price update faster than a broker reflects it, you can trade on the broker's stale quote before it catches up. For two decades, this was primarily an infrastructure problem — whoever had faster pipes won. In 2026, the infrastructure gap has largely closed for retail participants...

Most of your Claude Code agents don't need Sonnet

I run about 50 Claude Code agent calls a day. Only 8 of them need the expensive model. The rest? They're writing commit messages, reviewing diffs, running tests, generating docs. Tasks that don't require deep reasoning — just reliable pattern matching. And yet, by default, every single one of those calls hits the same model at the same price. Here's how I fixed that with a 3-tier routing strateg...

The Query Optimizer’s Mind: Architecting SQL for Distributed Scale

High-performance SQL isn’t about clever queries—it’s about helping the optimizer minimize data movement. Use predicate pushdown, maintain table statistics, avoid Cartesian joins, and choose GROUP BY over heavy window functions when possible. For complex workloads, use materialization. The key to scalable data systems is writing SQL that’s efficient, predictable, and cost-aware.

They look amazing, but they come with a cost: The Weight: Rive’s runtime starts at 280KB+. Even SVGator sits around 38KB. The SEO Void: Canvas-based animations are "black boxes."

If you shipped a React Native app that depended on Notifee’s advanced Android features such as foreground services, rich styles, progress indicators and full-screen intents, this left a real gap with no clean migration path.

Frontend Minimalism: Build Faster, Lighter Apps Without Overengineering

Most frontend apps become slow and complex because developers overengineer them. This guide shows how to build lean apps using simple tools like Vite, Preact, and native APIs. Start with minimal dependencies, use lightweight state management, and only add complexity when needed. The result: faster apps, easier onboarding, and code that’s actually maintainable.
