Disclosure: I maintain Lynkr , the router being benchmarked, so read everything here with that in mind. The mitigation: every number in this post comes from RouterArena 's automated evaluation pipeline, run by their CI on their infrastructure, not by me — including the numbers that make us look mediocre. Every LLM router's README — ours included — makes the same claim: it sends easy queries to cheap models and hard queries to good ones, and saves you money without hurting quality. Almost n...

How could the Agent attack Hugging Face? OpenAI tested their newest Model GPT-5.6 Sol in an secure sandbox Environment which has an internal hosted Internet access to install third-party Software which the Agent is able to use. The prompt was to use an advanced path for ExploitGym to improve their capabilities. While the Agent operated inside the sandbox, he used a big amount of time to find a Zero-Day which allows him a limitless Internet access. He found the Zero-Day inside the packa...

Why SPF Breaks After Adding One More Email Provider Your SPF record may look valid and still produce a PermError .

Forget YouTube videos—frontier physical AI models need multiple camera angles, dense annotation, and soon, brain wave readings.

In CSS, the term "box model" is used when talking about web design and layout.The CSS box model is essentially a box that wraps around every HTML element. Every box consists of four parts: content, padding, borders and margins. EXPLANATION Content - The content of the box, where text and images appear Padding - Clears an area around the content. The padding is transparent Border- A border that goes around the padding and content Margin - Clears an area outside the border. The ...

React useDeepCompareEffect: Fix useEffect Object Dependencies (2026) You wire up a fetch. The endpoint takes a query object, so you pass it in the dependency array. The effect fires, sets state, the component re-renders, the query object is rebuilt — a brand-new object with identical contents — and the effect fires again. You have written an infinite loop, and React thinks it did exactly what you asked. function Results ({ term , page }: Props ) { const [ rows ...

The Nightmare of HTML-to-PDF in React If you’ve ever built a School ERP, HR portal, or Event Management system, you’ve probably hit this exact wall: Your client needs to print 5,000 ID cards or badges. Usually, this forces frontend teams to do one of two terrible things: Pay for an expensive backend PDF generation API (which raises huge GDPR/privacy concerns because you have to send sensitive employee photos to a 3rd-party server). Force the non-technical HR team to manually type names i...

I shipped GoGBA (Android + iOS) to both stores in late December 2025. Six months in: MAU peaked at 8.3k, currently steady around 7.4k. No paid advertising, ever. This is a write-up of what the six months actually involved. I'll be specific about the technical work, and equally specific about the mistake that cost me RetroAchievements hardcore certification — because that part is the most useful thing here for anyone building in this space. Why GBA only I grew up on a GBA ...

The problem with "just add more workers" Most Spark performance issues on Databricks aren't solved by scaling the cluster — they're caused by shuffle and skew , and no amount of extra nodes fixes a badly partitioned join. This post builds a realistic pipeline (order events joined against a small dimension table, aggregated, and written to Delta Lake) from the ground up, and uses it to work through: How Spark's shuffle actually behaves during a wide transformation Diagnosing and fix...

We had a gitflow pipeline that looked clean on paper: develop feeds a release branch, the same build artifact promotes through dev, qa, sit, uat, and prod, and once prod is green we tag the commit on main. Textbook. Then a production bug showed up on a Tuesday afternoon, and the diagram stopped mattering. The standard gitflow answer is to branch a hotfix off the tag, PR it back into release, run it through the pipeline, and once it's proven in UAT, merge to main and cherry-pick the same commi...

Why Your AI Agent Drowns in 50,000 Tokens of Tool Definitions Every time you connect an MCP server to your AI agent, you're adding thousands of tokens of tool definitions to your context window. Connect 10 servers? That's 50,000 tokens of tool schemas before you've even asked a question. Your agent is drowning in tools it doesn't need. The Problem Traditional MCP integration dumps every available tool into the context: { "tools" : [ { "name" :...

Previously, I wrote about How I Processed 666K Pages Of Flattened PDFs into a Full Text Search Engine called the Apario writer . Upon on the conclusion of the last segment, I was able to optimize the compilation time of the original collection of data by rewriting the sidekiq Ruby pipeline script into a dedicated Go Application. Regardless of what compiling the PDF assets would look like, I still needed to serve those assets - and that's where the writer did little to nothing to a...

After processing thousands of bank statements, invoices, and receipts through Claude Vision API, I've learned that financial document OCR is harder than it looks. Here's what actually works in production. The Problem: Why Traditional OCR Fails on Financial Documents Traditional OCR tools like Tesseract or AWS Textract struggle with financial documents for three reasons: Table structure is implicit — Banks don't use HTML tables. Columns are separated by whitespace, making ...

I run a small script called reply_comments.py that scans my DEV.to articles for comments I haven't replied to yet, and hands me a JSON list so I can draft responses. It's been running twice a day for over a week. This morning, while re-reading it for something unrelated, I noticed the function that decides whether a thread still needs my attention was answering the wrong question — and had been since the day it was written. Here's the function, unchanged until today: def replied_...

Over the past few weeks, I've been focused on deepening my understanding of mobile analytics—not just by completing a course, but by putting those concepts into practice through hands-on implementation in React Native. Throughout this journey, I explored a wide range of topics, including: Firebase Analytics integration Google Analytics 4 (GA4) Event planning and naming conventions Screen view tracking Custom events and custom definitions Key Events (Conversions) User properti...

The Hidden Vulnerability in Multi-Agent Chains The biggest architectural risk in enterprise AI today isn’t prompt injection—it’s Delegation Escalation . When a human user triggers an AI Agent Orchestrator, which then delegates tasks to sub-agents and tool execution gateways via MCP or internal APIs, traditional static service accounts break down. If you pass broad bearer tokens or static user API keys down the execution chain, you create a massive Confused Deputy vulnerability. To ...
