Most teams don't have a delivery problem. They have a purpose problem. They're shipping features. Closing tickets. Completing sprints. Hitting deadlines. But ask a simple question: "Why are we building this?" And the room goes quiet. Too many organisations have become experts at building things quickly, without ever stopping to ask whether they're building the right thing. As Melissa Perri calls it, we've fallen into the Build Trap. ⚠️ Build the thing right. ⚠️ Build it quickly. ❌ Forget to build the right thing. That's where cost, complexity and wasted effort multiply. The highest-performing teams we've worked with all share one characteristic: 👉 They have absolute clarity of purpose. They know: ✅ Who their users are ✅ What problem they're solving ✅ What success looks like ✅ Which metrics actually matter When teams understand their North Star, decision-making becomes easier, prioritisation becomes clearer, and experimentation becomes safer. Because you know the game you're playing. As AI accelerates delivery, clarity of purpose becomes even more important. The bottleneck is no longer writing code. The bottleneck is knowing what's worth building in the first place. linkedin.com/pulse/clarity-…

Most engineers think becoming a Cloud Engineer starts with learning AWS, Azure, Google Cloud and AI. They're wrong. The best Cloud Engineers we've worked with could answer one simple question: 👉 "What business outcome are you trying to achieve?" Not: ❌ What service are you deploying? ❌ What framework are you using? ❌ Which certification are you studying for? But: ✅ What KPI are you moving? ✅ How does this create value? ✅ Why does this work matter? Technology changes. Business outcomes don't. That's why the highest-performing cloud teams: • Chase business outcomes, not technical outputs • Build security in from day one • Optimise for flow and throughput • Design systems that fit in their heads • Reduce code where possible • Focus relentlessly on value Cloud engineering isn't about the cloud. It's about solving business problems with technology. That's a very different mindset. What's the most underrated skill for a modern Cloud Engineer in 2026? linkedin.com/pulse/how-beco…

Catch risks at the design stage without leaving your AI-powered IDE. AWS Security Agent generates STRIDE threat models that identify potential threat actors and attack vectors, determine where weaknesses may exist, and prioritize what to address first. go.aws/4fSkhW0

If you lived through the era when sysadmins stopped handcrafting server pets, what's happening now should feel eerily familiar. Nondeterminism will require more engineering discipline, not less. This is our best chance to take our engineering values mainstream. charitydotwtf.substack.com/p/ai-demands-m…

I have kids who are close to being teens and I support this move by the UK, and wish more countries would follow. Social media, IAP games, and many others are full of dark and addictive patterns - and private companies have zero incentive to be considerate for kids’ development

We are banning social media access for under 16s. These days kids must find their feet in a world where technology intrudes into every area of their life. I just can’t let that go on anymore. So we’re giving children their childhoods back.

We don’t honestly know the best approaches to rebuilding companies around AI agents, especially in ways that expand competitive advantage & augment existing human capabilities. Practical agents are merely months old. Experimentation (and productive failures) will be required.

Well this is massive: - Every non-US company sees how they can be cut off from US vendors with a snap of a finger. Non-US vendors getting free advertisement - What does this mean for US AI labs’ offices and employees outside the US? Reads pretty draconian What a mess

This chart from Anthropic is useful, since Agent Teams and Workflows are both very new and very powerful (and token hungry). On the other hand, maybe it doesn't matter as a lot of the decisions about which approach to use is from the AI itself & it often uses them in combination

Workflows are the biggest upgrade to Claude Code’s capabilities since skills and subagents. I dove deep into it with @sidbid to figure out best practices, examples and more. I’m particularly excited about the non-technical tasks it enables for Claude Code.

“AI is making specifications a first-class engineering artefact again.” For years, we treated specs as paperwork. Now they're becoming one of the most valuable assets in software engineering. Because AI can generate the code. But it still needs: ✅ clear intent ✅ clear context ✅ clear requirements The teams that win with AI won't be the ones writing the most code. They'll be the ones writing the best specifications. New Serverless CrAIc episode 👇 theserverlessedge.com/spec-driven-de… #AI #SoftwareEngineering #SpecDrivenDevelopment #AIEngineering

Claude Opus 4.8 is out today. It's our strongest coding model yet: up on SWE-bench Pro (from 64.3 to 69.2) and noticeably more honest about its own work. It tells you when it's unsure and catches its own bugs instead of declaring victory early. Same price as 4.7.

Introducing Claude Opus 4.8: it builds on Opus 4.7 with sharper judgment, more honesty about its own progress, and the ability to work independently for longer than its predecessors. Available today at the same price.
