RAG is powerful. But like any powerful tool, the problem isn’t whether to use it — it’s when to use it. I’ve seen too many agentic pipelines that blindly trigger a semantic search on every single user query. The user says “thanks” and the system dutifully fires off an embedding call, scans a 10-million-document vector … Read more

Every production engineering team knows the pattern. A new project begins with energy. Product goals are clear. Deadlines are ambitious. Teams want to move quickly and deliver something customers can use. Then the real work starts. Infrastructure must be provisioned. CI/CD pipelines need to be set up. Secrets require management. Monitoring needs wiring. Databases need … Read more

YouTube has built a perfectly elegant economy where corporations pay to interrupt you, and you pay to not be interrupted. It’s extortion. It’s genius. It’s somehow both. By A Deeply Concerned Human Companies pay YouTube billions to force ads in front of viewers, while viewers pay YouTube monthly fees to avoid seeing those same ads. … Read more

Enterprise engineering teams face a widening gap between speed and reliability. Codebases are sprawling, AI now generates a significant share of code, and release cycles move faster than QA can keep up. The backlog is longer than ever, tests fail to find the most challenging edge-cases and firefighting drains time from innovation. Our systems and … Read more

Good enough until it isn’t: the database complacency trap A database is like a water heater. When all is well, it just does its job in the background. You don’t fantasize about replacing it or envy the one your friend just got. Really, you don’t even think about it — until something goes awry. But … Read more

You’ll likely find artificial intelligence (AI) agents appearing everywhere. These AI agents appear in your Teams sidebar, in your SharePoint document library, and as part of standard Office applications. What makes this so easy is that Microsoft allows virtually anyone within an organization to create their own dedicated AI agent in a matter of a … Read more

The whole rationale behind deploying AI to the extent that it threatens to decimate whole professions is premised on the fact that it leads to much enhanced productivity, reduced costs, and unprecedented profits. In other words, much more ROI or return on investment than would accrue if humans were employed to carry out the same … Read more

Building an application that handles a few hundred requests per minute is relatively straightforward. Building a system that maintains single-digit millisecond latency while handling hundreds of thousands of concurrent requests—all without exploding your cloud budget—is an entirely different engineering challenge. When your application outgrows standard architectures, lightweight frameworks like Express.js and Flask can require significant … Read more

The central unsolved problem in production DeFi agents is not capability. Existing frameworks can route swaps, monitor yields, and respond to on-chain events with low latency. The problem is verifiable constraint. What I mean here is building agents that are not merely instructed to respect user-defined boundaries, but architecturally incapable of violating them. Add an extra … Read more

Moving a machine learning model from a local Jupyter Notebook to an enterprise production environment is less about mathematical optimization and more about software reliability. In a development environment, datasets are static, edge cases are filtered out, and execution is synchronous. In production, however, data is dynamic, upstream dependencies change without warning, and models encounter … Read more

Musk’s xAI runs 46 gas turbines in Mississippi without air permits. I traced the full supply chain behind them — from $30M+ in Caterpillar equipment to TSMC’s €300M EUV lithography machines, from Lake Tahoe residents losing power to Wall Street’s $700B AI infrastructure spending. One AI data center pulls on 10+ industries, creates billions in … Read more

Schematic: Europe’s coordinated cyber-defence posture — city nodes, threat vectors, and regulatory stack. Data: Mordor Intelligence. Europe has long been perceived as the world’s most regulation-heavy technology market. In cybersecurity, that reputation is evolving into something more consequential: a coordinated industrial strategy. Most global tech narratives still frame Europe as the slow-moving regulator — the … Read more

I ran jscpd against 49 vibe-coded GitHub projects looking for code duplication patterns. Average duplication: 7.98% (above the 3-5% industry benchmark). But the unexpected finding wasn’t in the apps — it was in the skill libraries built to teach AI agents how to code. Those have 30-40% duplication rates, mostly in markdown instructions and CSS … Read more

Staying loyal to Progressive Web Application technology, despite the apparent ease with which they can be converted to become ‘native apps,’ can leave us feeling vulnerable.

If I want to sell AI visibility work, I have to be visible. Not on a marketing-deck level. On a “the model can answer questions about me without guessing” level. So, before I wrote a single outbound message about the service, I ran the checklist on my own site. This post is that checklist, with … Read more

I live close to nature. I regularly go for a run in the countryside. Over several years, during my runs, I’ve taken pictures from the same position, always roughly the same angle. I had a vague idea in the back of my mind, as an “artistic” project. One day, I’d turn those photos into a … Read more

In December 2024, Google announced that its Willow quantum chip completed a computation in minutes that would take the world’s best classical supercomputers longer than the age of the universe to solve.
