RFC 9880 and the IoT Validation Problem: From Standards Fragmentation to a Device-Model Compiler

RFC 9880 and the IoT Validation Problem: From Standards Fragmentation to a Device-Model Compiler The Internet of Things has a data-model problem that no amount of protocol engineering can fix. RFC 9880's Semantic Definition Format offers a way out — but only if we treat it as a language to compile, for data validation, not only as a document to read. TL;DR — IoT devices speak fiv...

Harness bugs, not model bugs

For six weeks, developers have been complaining that Claude got worse. You've seen the posts — "Claude Code is flaky", the AI-shrinkflation discourse. Yesterday, Anthropic shipped a postmortem. Three unrelated bugs, all in the Claude Code harness. The model weights and the API were never touched. That distinction is the whole point. What actually broke Default reasoning effort got ...

How I run my life on Markdown and the Stacklist MCP

Everyone I know is drowning in inputs. Slack threads. Gmail. Calendar invites. Granola meeting notes. Linear issues. Lightfield CRM follow-ups. Text messages.

Implement authentication for Next.js with external backend (JWT)

Introduction Usually when you build a new project from scratch with Next.js you don't create a separate backend because it adds more complexity and slow you down, especially for MVPs! We mostly go with solutions that don't let us worry or deeply invest in authentication like third party services such as Clerk, a BaaS like Supabase or even Better Auth, so we have auth ready in seconds a...

AI Accounting: 45 Seconds in a Form vs 10 Seconds in a Chat

We built 118 MCP tools for our SaaS. About 35 of them handle accounting: transactions, transfers, recurring rules, categories, currencies, financial accounts. We timed the same operations in our web forms and through Claude. The difference was larger than we expected - in both directions. This isn't a "forms are dead" post. It's a timing comparison with code. Some operations are 4x faster in conv...

How Scammers Use Automation to Scale Attacks Globally

The automation technology used is more advanced than many security measures anticipate. In February 2025, Interpol's Cybercrime Coordinated Action (IOCA) unit published details of an operation to dismantle...
