Privacy isn't a checkbox. It's not a statement in your terms of service. It's not a toggle in your settings app. Privacy is architecture. And most apps get this backwards. The Architecture Test Here's a simple test for any app that claims to be "privacy-first": If your server goes down, can anyone still access user data? If the answer is yes, your privacy is a policy question — not a technical guarantee. You've built a system where trust in the company replaces trust i...

The 2026 World Cup has $3.89 billion bet on it across Polymarket. That's not retail money — that's whales. I built WhaleTrack to track exactly what those big wallets are doing. Here's the stack: Backend: Node.js server fetching live data via Bullpen CLI Frontend: Vanilla JS, real-time updates Data: Polymarket CLOB API via Bullpen Analytics: Google Analytics for traffic tracking The hardest part wasn't the code — it was getting users. Pure SEO and content distribution (Reddit, Twitter, ...

AI coding assistants are great at writing code and terrible at knowing when to write it. Ask one to build a feature and it will happily jump straight to implementation, skipping the questions a good engineer asks first: what exactly are we building, why, what are the risks, and how should it be broken down? The result is fast output that often solves the wrong problem. AWS's AI-DLC (AI-Driven Development Life Cycle) is an attempt to fix that gap. It's an open-source set of workflow rules ...

If you're a solo founder or small team shipping on GitHub, at some point someone asked you: "what changed in the last release?" And if you're honest with yourself, your answer was probably a Notion page nobody reads, a GitHub releases tab your users don't know exists, or "I'll get to it." A changelog sounds like a low-priority vanity feature. But here's what I've learned building a SaaS: when you ship frequently and users don't know what changed, they churn quietly — not because the produc...

Back when we introduced MCP support , we ended on a teaser: Phase 3 would tackle Sampling —letting servers request completions from the host instead of only exposing tools and resources to it. NodeLLM 1.17 delivers on that, and pairs it with a second, unrelated but overdue improvement: precise control over how tool calls execute, now available consistently in both core and the ORM persistence layer. 🔄 MCP Sampling: Closing the Loop Sampling inverts the usual MCP direction. Inst...

A certain amount of complexity can never be removed from an interface; it can only be shifted between the user and the system (Tesler's Law). B2C products manage this well because designers share the user's everyday reality.

Let's learn about Ab Testing via these 67 free blog posts. They are ordered by HackerNoon reader engagement data. Visit the Learn Repo or LearnRepo.com to find the most read blog posts about any technology. A/B testing is a method of comparing two versions of a webpage or app feature to determine which performs better. It matters for data-driven decision-making, allowing businesses to optimize user experience, conversion rates, and product effectiveness through empirical evidence. 1. ...

Two hundred and fifty years after the signing of the Declaration of Independence, a new commercial asks: What if the Founding Fathers had access to Google Workspace?

"Who owns this code?" is a question most teams answer with folklore. GitHub's CODEOWNERS file is supposed to answer it, but it gets written once, rots quietly, and keeps routing reviews to people who changed teams a year ago. checkOwners answers it from evidence instead. It's an open-source CLI that reads your git history and writes your CODEOWNERS file for you. Pure git, no LLMs. fortyOneTech / checkOwners I...

Claude Code is remarkably capable. But out of the box it does what you prompt — and most prompts quietly skip the checks a senior engineer would never skip. Ask it to "fix the slow endpoint" and it will happily eager-load a relation and call it done, without ever proving the slowness was an N+1 or measuring the result. The capability is there. The discipline is not — because you did not ask for it. The fix is not a bigger prompt. It is encoding the workflow as a skill . What ...

The Cascading Failure That Took Down Everything Our payment service went down for 3 minutes. No big deal, right? Except every service that called payments kept retrying. The retry storms consumed all available connections. Within 10 minutes, all 12 services were down. 3 minutes of one service failing became 45 minutes of total outage. Circuit breakers prevent this. How Circuit Breakers Work State Machine: CLOSED ──(failures exceed threshold)──→ OPEN ↑ ...

Day 12. I tested 15 popular Android apps for accessibility. What I found revealed who gets left behind. I took a week off from coding. Not because I was stuck. Not because I was tired. But because I needed to understand something that had been nagging at me since Day 10. Why does my AI agent work flawlessly on WhatsApp but completely fail on my banking app? The answer took a week of testing, documenting, and thinking. And what I found changed the direction of this entire project. ...

Two separate models — one writing the code, one reviewing the diff — shipped a one-word bug to staging. Both ran local checks. Both came back green. The fix they missed was not exotic or subtle. It was written down, in plain English, in a file sitting in the same directory as the change. That last detail is the one worth staying with. This is not a story about a model being wrong. Both models were, within the job they were given, correct. It is a story about where verification stops looking —...

I am developing a service to use on my computer, that allow the user to create a network on their system to connect to it from other part of the world. The problem is that i don't want to depend on a local ZeroTier to extract the authtoken.secret from it. Is there a way to create a token for each user that use this service once the system is online the first time? This network must be approved by ZeroTier because the user have to connect throw ZeroTier to this network.

AI agents can now generate PDFs Large language models are great at producing Markdown. What they can't do is turn that Markdown into a polished, branded PDF. That's always been a manual step — copy the output, paste it somewhere, fiddle with formatting, export. PaperQuire v0.3.0 removes that step entirely. The app now includes a built-in Model Context Protocol (MCP) server. Any MCP-compatible AI agent — Claude, ChatGPT, Copilot, or others — can call PaperQuire directly as a tool to rend...

For the last couple of years, AI has become a regular part of my development workflow. Whether it's debugging a React component, generating boilerplate code, or explaining an unfamiliar concept, AI has saved me a lot of time. Like many developers, I treated it as an assistant that responds to prompts. Recently, I started noticing a new term appearing in articles, conference talks, and developer discussions: Agentic Software Development and Now Looping. At first, I assumed it was just...

TL;DR: Application code isn't the only thing that ships vulnerabilities — your Terraform does too. I wrote an intentionally insecure AWS configuration, scanned it with Checkov (a SAST tool for Infrastructure as Code, listed on the OWASP Source Code Analysis Tools page), went from 35 failed checks to 0 , and wired the scan into GitHub Actions. Full code: GitHub repo → SAST for infrastructure? Yes, that's a thing In my previous article I used Bandit to find security b...

Apple shipped an official Safari MCP server in Safari Technology Preview 247, and it signals a real shift in how AI agents interact with browsers for debugging, testing, and automation. In early July 2026, Safari Technology Preview 247 shipped with something that caught the attention of every developer who uses AI agents for debugging. Apple included an official Safari MCP server, a first-party implementation of the Model Context Protocol that lets AI assistants control Safari for web debugg...

TL;DR: I compared the major CI/CD tools for test automation (GitHub Actions, GitLab CI, Jenkins, CircleCI, Travis CI, TeamCity, Bitbucket Pipelines, Tekton, Harness) — and instead of stopping at a table, I wrote the exact same test pipeline three times : once for GitHub Actions (running live), once for GitLab CI, and once as a Jenkinsfile, all in one public repo so you can compare the syntax line by line.
