The Dual Nature of Events in Event-Driven Architecture
The article argues that events in event-driven systems serve two purposes at once: they trigger actions and carry data. Good event design must keep both the business reason and the changed state in view.
Srinivasa Ramanujan Was a Genius. Math Is Still Catching Up.
The article traces Ramanujan’s rise, his letters to Hardy, and the continuing spread of his identities across mathematics, including recent work in algebraic geometry.
Can We Close the Loop in 2026?
The article argues that useful agents combine self-awareness about their tools and limits with loop-closing verification against external signals, and that this is moving from scaffolding toward default behavior.
8 Predictions for 2026. What comes next in AI?
The page predicts 2026 will bring generative UI, edge-based personal agents, smarter home assistants, AI-labeled content, and biometric verification as AI systems spread into daily life.
The End of Programming as We Know It
The article argues that AI will not replace programmers, but it will change programming into higher-level work, while creating new demand, new skills, and new roles around AI systems.
I am tired of AI
The author says AI is useful in some cases, but argues that marketing hype, AI-generated test tools, AI-written conference proposals, and dull synthetic content have become exhausting and overused.
A Guide to Which AI to Use in the Agentic Era
The guide says “using AI” now means choosing among models, apps, and harnesses, and that for serious work the app and harness often matter as much as the model.
How I built a sub-500ms latency voice agent from scratch
The post argues that voice agents are an orchestration problem, and shows how a streaming pipeline with turn detection, cancellation, geography, and fast model choice cut latency from about 1.6s to around 400ms.
Power in the Age of Intelligence
The essay argues that AI and other new technologies increase concentration: the right question is not how software keeps moats, but which companies own scarce industry assets, break constraints, and expand from the high ground.
The current balance of power in open models
The piece argues that Chinese open-weight models now lead adoption and benchmarks, while U.S. models still matter in research and enterprise use. Open models are becoming economically central and a growing policy and safety issue.
I switched to a vertical mouse and I'm never looking back. Here's why.
The piece argues that vertical mice reduce wrist and arm torsion, take some getting used to, and can feel more natural for long computer use once adjusted to.
10 hot programming trends — and 10 going cold
The article pairs rising and fading programming approaches, arguing that cost, safety, privacy, and workflow are shifting interest from clouds, C/C++, REST, and SPAs toward Rust, Wasm, GraphQL, static site generators, and more.
The Surprising Cost of Bad Estimates
Bad estimates do more than miss dates: they erode credibility with stakeholders, weaken collaboration, and make future planning discussions harder. Better planning starts by understanding why plans fail and accounting for unknown work.
Agile Spikes Deliver Knowledge So Teams Can Deliver Products
Spikes are time-boxed research work that helps agile teams reduce excess uncertainty, make better decisions, and learn enough to deliver features later without using spikes too often.
Why use aspect-oriented programming
