Audit Your Codebase Before Migrating to Stateless MCP

MCP 2026-07-28 removes protocol-level sessions, the required initialization handshake, and Mcp-Session-Id. Before deleting those code paths, find the application state they were hiding. This tutorial builds a dependency scanner, classifies each match by migration risk, and turns the results into a staged rollout checklist. This is a static audit, not proof that a deployment is compatible. It fin...

Dependency Confusion Attacks — How They Work and How to Protect Your Pipeline

dependency confusion attack helped security researcher Alex Birsan earn $130,000 in bug bounties after demonstrating that build systems at Apple, Microsoft, PayPal, Uber, Yelp, Tesla, and 30+ other companies could be tricked into running code from public package registries. The attack did not exploit a single CVE. It exploited a package manager assumption: when public and private registries conta...

FCC Blocks New Foreign-Produced Robots and Power Inverters Over Cyber Risks

The Federal Communications Commission (FCC) added foreign-produced mobile robots and networked power inverters to its Covered List on July 28. The move generally prevents new models from receiving the equipment authorization required for import, marketing, or sale in the US. Previously authorized models can still be sold, and devices people already own are unaffected. Federal purchases and use

I want to give my PC a second life (clean it up, optimize it, and make it look minimalist). Any recommendations?

Hey everyone! I’ve been wanting to give my PC a fresh start for quite a while. My goal isn’t just to free up some storage space—I want to completely reorganize it, get rid of unnecessary files and programs, make Windows feel lighter, and give it a clean, minimalist look. The biggest issue is that my PC isn’t particularly powerful, so a lot of Windows’ built-in tools or more advanced programs take ...

Loop Engineering Is Mostly Papering Over a Model That Won't Converge

Disclosure: I maintain Lynkr, an open-source LLM gateway with loop-guard middleware, so I have a stake in this argument. Read this as a thesis to challenge, not a neutral survey. Agent discourse has shifted from prompts to loops: the read-act-observe cycle that keeps running until the model decides it's done. My contrarian take is that most so-called loop engineering is optimizing the wrong varia...

Claude Code Team Memory: CLAUDE.md, Git, or MCP?

If a team wants its Claude Code agents to remember decisions and context, three tools come up: a CLAUDE.md file, Git itself, and an MCP memory server. They're often framed as competitors. They're not — they cover different layers. Here's the boundary. CLAUDE.md: standing instructions, per repo CLAUDE.md is a file Claude Code reads automatically. It's the right home for stable, repo-sco...

Best way to store a JS accessible and amateur user editable spreadsheet

So I have an Excel workbook that stores multiple sheets of data, and I've been using basic HTML, CSS and JS code to make charts out of the data, which is read using the XLSX library for Javascript, and displaying them on a website. The problem is that this file is stored locally on my computer, and I need it to be stored somewhere where it can still be accessed by Javascript functions while also b...

Agentic Workflows That Survive Real Inputs

Agentic Workflows That Survive Real Inputs Most agent demos work because the demo input is clean. Real inputs are not. They arrive half-formed, with missing fields, contradictory context, PDFs that are actually images, and users who change their mind mid-thread. The gap between a working demo and a workflow that runs unattended for six months is almost entirely about how you decompose t...

AI Agent Stack in 2026: LangGraph vs Custom vs DIY

AI Agent Stack in 2026: LangGraph vs Custom vs DIY I ship agents into production most weeks, and the framework question keeps coming back in every kickoff call. The honest answer is that the "right" stack depends on how much branching, how much state, and how much blast radius you can tolerate. I've built the same agent three ways in the last year, and the trade-offs are sharper than th...

Hi, I'm Boris — a PHP developer whose deepest experience is TYPO3, with Laravel and Filament a newer and growing focus. A lot of that work has been integrations that quietly need to just work: payments, webhooks, notifications. This one is about e-invoicing, which is now mandatory in a growing list of EU countries and is coming for the rest. If you build anything that issues invoices B2B in Europ...

Vercel pricing 2026: what you actually pay for a real Next.js project

Vercel pricing looks simple on the surface — free, $20/seat/month, call us — but the bill a real Next.js project generates depends almost entirely on a handful of usage meters that aren't obvious until you've already deployed. Here is what those meters actually are, what triggers them, and what a mid-traffic marketing site should expect to pay in 2026. What Hobby actually allows commerci...
