What GitHub Copilot's New July 2026 Agentic Review Features Can Teach Beginners About Trust in AI Coding

The biggest shift in AI-assisted coding lately is not that tools can write code faster. It is that they can now write reviews faster too. On July 29, 2026, GitHub announced that Copilot code review gained GA support for agent skills and MCP-style integrations. In plain terms, AI can now read a larger chunk of your project context and run more structured checks without you manually typing every c...

MCP Went Stateless: Migrating to the 2026-07-28 Spec (and Proving It Works)

📖 TL;DR The 2026-07-28 spec shipped final on July 28, 2026 (RC locked May 21). It is the biggest revision since MCP launched. Sessions are gone. No initialize, no Mcp-Session-Id. Every request is self-contained. TypeScript ships as two new packages — @modelcontextprotocol/client@2 and @modelcontextprotocol/server@2. The old @modelcontextprotocol/sdk line lives on at 1.x for 2025-era servers. ...

WHOIS is gone, RDAP replaced it, and a 404 does not mean what you think

If you last touched domain lookups a few years ago, the thing you remember is WHOIS: a plaintext protocol on port 43 that returned an unparseable wall of text in a different shape from every registry. It is effectively gone. RDAP replaced it, it is RFC 9083, it returns JSON, and every gTLD registry is required to run one. This is one of the rare cases where the standards process produced somethin...

Agendando Tarefas no Linux com Systemd Timer

🇺🇸 English version here. Rotinas como backups automáticos, limpeza de logs ou qualquer script que precise rodar em um horário fixo tradicionalmente são resolvidas com cron. Mas em distribuições Linux modernas baseadas em systemd, existe uma alternativa nativa e mais robusta: os Systemd Timers. Comparado ao cron, o Systemd Timer traz algumas vantagens práticas: integração direta com os logs do jo...

Building Reliable AI Agents: Lessons from Failed Bots, FSMs, and the Hidden Costs of Agentic Workflows

Originally published on tamiz.pro. The initial promise of Generative AI was straightforward: automate knowledge work. Early implementations often looked like sophisticated chatbots—stateless, reactive, and driven by a single prompt-response cycle. But as the industry matured, the demand shifted from conversational interfaces to Agentic Workflows: systems that perceive, plan, act, and observe to a...

Supply Chain Attacks verstehen: Praktische Tipps zur Abwehr von 2026

Hook‑Einleitung „Ich dachte, mein Code ist sicher, weil ich ihn selbst geschrieben habe.“ – Diese Aussage klingt fast wie ein Mantra für viele Entwickler. In der Realität steht das Wort Supply‑Chain jedoch für eine unsichtbare Angriffsfläche, die jede Zeile Code, jedes Docker‑Image und sogar jede Firmware‑Version durchdringen kann. Im letzten Jahr allein haben neun‑fache Unternehmensaus...

Not a hype list. These are the three MCP servers I have running right now in Claude Desktop. 1. Filesystem mcp-hub install @modelcontextprotocol/server-filesystem I use this to let Claude read project files directly instead of me copy-pasting code. Configure it to point at your project root. Real usage: "Read the auth module and explain how the token validation works." ...

Giving every AI agent its own mailbox: the architecture behind a self-hosted MCP mail server

My agents keep needing to read email. Signup codes, verification links, password resets: every automated workflow that touches a third-party service eventually hits an inbox. There are hosted APIs for this, and they work fine until you think about what's actually in those emails. In a signup flow, the message with the verification code is the account credential. Every one of them passes through so...

A developer at my company used Claude Code to argue with infrastructure in Teams, and it felt like a Black Mirror episode

A pipeline build was creating more than 5 GB every run and filling up company storage, so infrastructure paused it. The developer responsible has been at the company for 20 years. Instead of explaining the issue himself, he kept posting screenshots of Claude Code telling him what to say and how to argue that the build should be unpaused. Claude suggested off-topic things (like just accepting that ...

Durable, persistent memory for agents

Context windows make agents look stateful right up until the moment they need to resume tomorrow, survive a restart, or remember a user preference from last week. When facts, workflow progress, and approvals live only in the prompt, every new turn becomes a reconstruction job, and the failure is architectural rather than model-level. The most useful design rule here is simple: keep authoritative ...
