I Audited My Own Open Source Library and Found 9 Security Bugs. Here's Every One.

Hey dev.to 👋 If you've read my previous post about layercache, you know it's a multi-layer caching library for Node.js — Memory → Redis → Disk behind a single get() call, with stampede prevention, tag invalidation, circuit breaking, and all the production-grade stuff you eventually need. Today I'm releasing v1.3.3, and it's different from all the previous releases. No new features. No benchmark...

How couples can split bills, chores & date nights fairly in Notion (2026)

It's 11pm on a Tuesday. Mika is folding laundry. Her partner Ren is on the couch scrolling. She's done dishes 4 nights in a row. He paid the electric bill last week and thinks they're even. Neither of them is actually keeping score — but both of them feel like they're losing. This is how most cohabiting couples fight. Not about the big stuff. About the invisible ledger that nobody agreed to but e...

The Constraint Paradox: Why Less AI Freedom Produces Better Code

LangChain jumped from 52.8% to 66.5% on Terminal Bench 2.0 by constraining their agent, not upgrading the model. Running at maximum reasoning budget actually scored worse. Three data points prove it: freedom is the enemy of AI agent reliability. Two approaches. Same model. Different results: # Approach A: Give the agent more freedom → Upgrade model, add more tools, increase context w...

Is a Data Science Bootcamp Worth It in 2026?

If you’re asking data science bootcamp worth it, you’re really asking a sharper question: will a bootcamp reliably turn your time and money into employable skills faster than self-study? Sometimes yes—but only under specific conditions that most ads conveniently skip. What “worth it” actually means (ROI, not hype) A bootcamp is “worth it” when it beats your next-best alternative on tim...

A Discord Group Accessed a Restricted AI That Finds Zero-Day Bugs -Here’s How It Happened

🚨 This is NOT a typical “AI breach” this is worse. A small Discord group just got unauthorized access to one of the most powerful AI security tools ever built. Let that sink in. This isn’t just any AI. This model (Mythos) is designed to: → Find zero-day vulnerabilities → Break down operating systems & browsers → Potentially simulate real cyberattacks And it was supposed to be highly restr...

Tell HN: An app is silently installing itself on my iPhone every day

Every day for the past 3 days around 1pm EST the 'Headspace' app has been silently appearing on my iPhone (13 Pro). Automatic downloads are turned off and I've updated to the latest iOS since this started happening.I googled around and found a couple reddit threads with people reporting the exact same thing starting 2 or 3 days ago.

ntop vs Commercial Traffic Analyzers: When Free Tools Hit Their Limits

Most teams do not suffer from a total lack of monitoring. They suffer from the wrong kind of visibility. They can see interface utilization, CPU curves, and generic uptime checks. But when users say “the app is slow,” “VoIP is choppy,” or “Wi-Fi keeps dropping,” those dashboards rarely explain why the experience broke. The common failure pattern A modern operations team usually starts...

How a 3-Location Dental Group Doubled Patients, and What It Teaches Us About How to Grow a Restaurant Chain Without a Big Marketing Budget

Everyone wants to talk about sophisticated marketing funnels. They map out complex user journeys with branching logic, retargeting pixels, and multi-touch attribution models. It all looks great on a whiteboard. But here’s a truth I’ve learned after eight years of running campaigns: most of that is useless if your business’s basic digital identity is broken. We recently doubled the new patient fl...

80% of AI Projects in Banks Fail - Here’s Why (And How We Fixed It)

Banks invested billions in AI. Fraud detection. Credit scoring. Customer experience. Risk modeling. The promise was massive. But here’s the uncomfortable truth: Most AI projects never make it to production. Not because the models don’t work. But because everything around them fails. From my experience building AI systems in banking, the pattern is always the same. The Real Pro...

How I Fixed a 42/100 Lighthouse Score on a B2B 3D WebGL Landing Page (and Open-Sourced the Fix)

A few weeks ago, I was building a B2B landing page that embedded an industrial 3D model using <model-viewer>. The page looked fantastic. Then I ran Lighthouse. Score: 42/100. Here are the silent killers I found - and what made them non-obvious: 1. The Font Weight Trap (8 requests instead of 3) Google Fonts was loading wght@300;400;500;600;700;800. That's 6 weights for Inter plu...

How I built a demo-first sales tool for freelance web designers

Most freelance web designers do not lose because they cannot build good websites. They lose because getting in front of the right local business owner is slow. The usual pitch is abstract: I can build you a better website. That asks the business owner to imagine the result, trust the designer, and care enough to keep talking. I wanted to test a different motion: I made you a quick demo. Wa...

Building Self-Healing Selenium Frameworks with AI

Building Self-Healing Selenium Frameworks with AI One of the biggest pain points in UI test automation is flaky locators. A developer renames a class, restructures a component, and suddenly 40 tests are failing — not because the feature broke, but because the test couldn't find the element. Self-healing frameworks solve this. With a bit of AI in the mix, your tests can recover from ...
