A follow-up to “The Engine Room Principle: Why Real Alpha Engineers Never Leave the Trenches” I have spent this series arguing that the Alpha Engineer never leaves the engine room. That the title on the door changes but the hands on the code do not. That’s still true. But there’s a second half to that … Read more

Both parties are fighting over whether to build the box. Neither is asking what the box does with what it makes. Every prompt you type ends as heat. The tokens stream back, the answer appears, and somewhere in a windowless building, a rack of GPUs has turned a few joules of electricity into a few … Read more

Just a few years ago, large language models, or LLMs, seemed above all to be extraordinary tools for working with text: writing, summarizing, translating, and answering questions. Then they learned to understand and generate images, sounds, and video. They gained the ability to tackle increasingly complex problems through forms of reasoning, to use external tools, … Read more

The other harness engineers On July 1, the European Space Agency posted an opening for a Harness Engineer at its technology center in the Netherlands. The job has nothing to do with AI. On a spacecraft, the harness is the bundle of wires that carries power and signals between components, the part that keeps an … Read more

Old code, new AI, same unwritten test suite. TL;DR: Patch code that never had a test written for it, and every quick fix becomes tomorrow’s outage. Common Mistake ❌ You assume a decades old, stable feature must have some kind of safety net, because it has been shipping without complaints for almost twenty years. Automated … Read more

Two power walls, twenty-two years apart In May 2004, Intel cancelled Tejas and Jayhawk. The chips worked on paper. They just couldn’t be cooled. Dennard scaling (the rule that let you shrink transistors, drop voltage, and keep total chip power flat) had stopped holding, leakage current was climbing exponentially, and power density was heading past … Read more

Cybersecurity’s center of gravity is shifting. Cloud infrastructure, software supply chains, AI agents, data security, and autonomous defense are creating new categories and giving a new generation of security CEOs plenty to talk about. These 11 executives stand out not necessarily because they run the largest cybersecurity companies, but because their companies and ideas are … Read more

A multidimensional study for model selection and agentic workflows Research date: September 7, 2026 Bottom line: the two models have near-identical base pricing and long-context specifications. Their meaningful differences lie in agent engineering, tool ecosystems, cache economics, safety boundaries, and existing platform fit. Astra is the stronger starting point for complex execution, science, and computer use … Read more

Every computer has its preferred way it wants you to remotely access that desktop. I prefer none of them. Perhaps you feel the same. Microsoft now packs its official remote desktop tool inside the confusingly named app “Windows.” Macs have you flip switches inside the “Sharing” settings to open access to third-party VNC applications. Linux is, well, Linux, … Read more

A model can work through a market question, weigh the alternatives and settle on a trade in under a second. Until recently it had nowhere to send that decision. Financial rails have been automated for decades. Orders route by machine, payments clear by machine, and settlement finishes without anyone touching it. But every one of … Read more

Every graceful shutdown guide for Kubernetes tells the same story. The pod gets SIGTERM. The endpoint leaves rotation. Traffic stops arriving. Your handler finishes the in-flight work and exits. It is a reasonable story. I wanted to know if it is true. Not plausible. Measured, with timestamps. So I built drainwatch. It is a small … Read more

Years ago, a colleague of mine told me about two pockets of foreign land surrounded by Switzerland: Campione d’Italia and Büsingen am Hochrhein, respectively, in Italy and Germany. Both are enclaves of their respective country in Swiss territory: An enclave is a part of the territory of a state that is enclosed within the territory … Read more

In a July interview with The Economist, Elon Musk predicts that in five years’ time AI will surpass all human intelligence combined, and in ten years, there will be almost nothing that a machine cannot do better than a human. Work will cease to be a necessity – it will become something like a vegetable … Read more

Every organization running both Snowflake and Databricks eventually hits the same argument: which platform gets to own this dataset? Not because either tool is bad — plenty of shops run both deliberately — but because whichever platform doesn’t land the workload also loses first-class access to the data. Land it on Databricks, and anyone on … Read more

Reputation repair is a separate task from reputation management. Maintenance ensures that a good image stays good. Repair begins when the problem is already on page one: negative coverage in the press, litigation case file, defamation on forums, organized review attacks, or outdated information coming back through an AI-powered answer bot whenever someone asks. It’s … Read more

So, unless you’ve been living under a rock, you know that Marvel’s Wolverine has been one of the most talked-about games in the last week or so. People are saying it’s mediocre, some people are saying it’s a ton of fun, and some are just enjoying the memes. We’re not here to talk about any … Read more

Caching API responses at the edge sounds great until you hit the invalidation problem. A TTL that’s too short and your origin keeps getting hammered, too long and your users see stale data for who knows how long. If what you’re looking for is to cache aggressively and purge surgically, the moment something changes and … Read more

Imagine a company that gives three departments their own AI agents. Sales configures its agent to improve conversions and authorises it to offer selected concessions. Finance configures another to protect margins and reject spending outside agreed limits. Customer support uses a third to resolve requests within a fixed service allowance. A customer accepts an offer … Read more

We are officially past the point where enterprise platforms operate strictly on fixed logic. Today’s systems process context, make real-time decisions, and directly shape business outcomes. As a software engineer embedding generative AI into large-scale enterprise architectures, I’ve had a front-row seat to this shift. The mandate for engineering teams hasn’t changed; we still need … Read more

You are, right now, more powerful than any king, president, or CEO from our past. I’m not joking. What you are able to do, unlike those kings or past presidents, is summon a passable doctor, lawyer, translator, and engineer on demand, at any hour, for very little cost. This is the beauty of Generative AI, … Read more

According to the American Heritage Dictionary, the gatekeeper is one who is in charge of a passage through a gate, one who monitors or oversees the actions of others. Research from the 1940s portrayed housewives as gatekeepers in charge of the family food channel during World War II. The technological gatekeeper, a couple decades later, … Read more

There is a moment in every bootstrapped developer’s life when a “clever, free hack” turns into a chaotic operational nightmare. For me, that moment hit right before Black Friday and Cyber Monday. Our lean, modular pipeline—drafting in Notion, cleaning up grammar via a ghostwriter, scraping links into CSVs, pushing assets to GitHub, and sending dirt-cheap … Read more

Artificial intelligence has changed how marketing teams create content. A single prompt can now produce a complete article, landing page, or product description in seconds — structured, readable, persuasive, and often aligned with a brand’s voice. But many companies discover a problem only after publishing: AI can produce content that looks trustworthy while containing information … Read more

From Principles to Pipelines In Part 1, we made the case that an AI system is only as effective as the information it receives, and we described what makes context reliable: relevance, freshness, completeness, trustworthiness, and authorization. Those five dimensions are useful as a checklist, but they raise an obvious follow-up question. How do you … Read more
