An AI Skill is a packaged capability that an agent can call on demand. Think of it like an app on a phone or an extension in a browser. The agent is the operating system, and Skills are the third-party software it installs to book travel, move funds, query a database, or sign a transaction. … Read more

A Practical and Memorable Framework to Generate Consistent, High-Quality Outputs from AI (LLMs) Most folks use AI in sub-optimal ways, including some of the tech professionals. I have been in Technical Product Management for years and even I make basic mistakes every now and then. The issue is that most people are confident (erroneously) of … Read more

We didn’t originally plan to write this article. At some point, while comparing notes between our teams and the tools we use every day, we kept coming back to the same realization: software interaction has changed more in the last couple of years than it did in the decade before that. And most people barely … Read more

There is a business race unlike anything the 21st century has seen. It’s on the scale of Rockefeller vs Carnegie multiplied by 2. Like happened with the aforementioned gentlemen, two other men are racing to become the ultimate richest men on earth. The world’s first trillionaires, with change. Michael Saylor We start with Michael Saylor, … Read more

Table of Links I. Introduction II. Pseudoscience III. Unidentified Assumption IV. False Assumption V. Objection VI. Conclusion and References V. OBJECTION One might object that the argument in this paper rests on the assumption that quantum mechanics implies indeterminism. Proponents of a deterministic block universe, including those who hold the Many Worlds Interpretation (“MWI”) of … Read more

It’s very reasonable for startups to view other startups as their competition. If you’re building a CRM, other CRMs are gunning for the same market share you have your eye on. If you’re building a project management tool, there are already more than enough project management tools trying to convince teams they are the one … Read more

Every M&A deal has a moment where someone realizes the integration plan was missing something obvious, and that moment almost always arrives after the deal has closed, the timeline is fixed, and the budget has been spent on everything else. That something is usually email, and it is usually a disaster. This is not a … Read more

How Martin Kleppmann’s iconic book evolved for AI and cloud-native architectures Since its release in 2017, Designing Data-Intensive Applications (DDIA) has become known as the bible for anyone working on large-scale, data-driven systems. The book’s focus on fundamentals (like storage engines, replication, and partitioning) has helped it age well. Still, the world of distributed systems has evolved … Read more

In the previous post, I described the Seasons project: a time-lapse of hundreds of pictures taken from nearly the same viewpoint over the years. The hardest challenge wasn’t taking the pictures or assembling them, but aligning them. You might have noticed the nearly part about viewpoint in the above paragraph. Indeed, it’s an approximation. I’m … Read more

There is a distinct lifecycle when developers build with LLMs. Phase one is pure awe: you ask a model to write a Python script or debug an async function, and it spits out working code in seconds. Phase two is ambition: you try to move past simple chat windows and build an autonomous AI agent … Read more

After eight years of trading EUR/USD, I kept running into the same frustration: a strategy that printed money for two years would suddenly stop working — not gradually, but almost overnight. No obvious reason. Same logic, same execution, same pair. It just… stopped. The usual explanation is “the edge decayed” or “the market adapted.” But … Read more

:::tip JSON.parse hit a limit we needed to go past, so we abandoned it and used a simdjson wrapper. ::: This article provides a practical guide to react-native-fast-json, when to use it, how to install it, and patterns that keep memory under control. The problem we hit. Our app needed to read a ~250 MBJSON … Read more

I have been developing enterprise applications with OutSystems for several years already. Long enough to be critical. Long enough to be sure that some mistakes will not be repeated again. And long enough to know that the most dangerous belief you can take into a project is that OutSystems takes care of your application’s security. … Read more

Most LLM apps fire one giant prompt and pray. The ones that feel fast in production split the work into a planning call plus parallel per-item expansion. You get three wins for free: a much faster time-to-first-byte, real parallelism, and bug isolation when something breaks. The cost is one extra request. The math almost always … Read more

Imagine asking your AI assistant: “When does my driving license expire?” Simple question. But to answer it, the AI needs to find a photo of your license in your gallery, or locate a renewal confirmation buried in your email, or pull the date from a government app on your phone. It needs to reach across … Read more

This article reexamines the famous “All men are mortal, Socrates is a man” syllogism through the lens of modern pedagogy and philosophy. While acknowledging the formal correctness of deductive logic itself, the author argues that the example has become outdated, philosophically loaded, and pedagogically confusing for modern students because its premises involve unresolved questions about … Read more

Engineering organisations measure almost everything today. Deployments. Story points. Velocity. Pull requests. Jira tickets. Lines of code. CPU utilisation. Incident counts. Yet many leadership teams still cannot answer the questions that actually matter. Are teams getting faster? Are engineers overloaded? Is platform investment reducing friction? Is reliability improving sustainably? Are we shipping value or just … Read more

You just doubled the RAM on your database server to handle a climb in p95 latency. You expect the extra memory to absorb your growing dataset and bring those 45ms spikes back down to 8ms. Instead, the dashboard shows minimal improvement. Write latency remains high, and query response times stay variable. The problem isn’t that … Read more

Modern enterprise AI and data platforms are becoming too operationally complex for traditional reactive monitoring systems. This article explores how self-healing infrastructure architectures can combine telemetry, anomaly detection, autonomous remediation, governance-aware orchestration, and operational learning to create adaptive enterprise reliability systems.

From the Gobi Desert to the Arctic Circle, a generation of private rocket startups is finally bending metal. 2026 is the year they either reach orbit—or run out of cash.

The next enterprise AI risk is not that a chatbot writes a bad email. It is that an AI agent quietly enters the operational layer of the company and starts ranking priorities, routing approvals, classifying risk, delaying purchases, escalating tickets, flagging customers, and shaping managerial decisions before anyone calls it management. Companies still describe these … Read more

Most AI products don’t fail because the model is bad. They fail because the product decisions around the model are wrong — or absent. Activation looks healthy in week one, then collapses in week two. Generation counts climb while export and approval rates stay flat. Users try the AI feature once, mark it as “interesting,” … Read more

For hundreds of Solana validators, November 2, 2022, began with an unresponsive node and a suspended server instance. Germany-based Hetzner, a favorite of developers for its affordable pricing, began suspending Solana validators without warning or any breathing room. The Hetzner ban on Solana validators was not a targeted action against one operator or one network. … Read more

Layoffs are rising, revenues are shrinking, and the rules have changed. Here are 7 practical strategies I use with startup founders to generate revenue and keep great talent.

The internet got so used to low-effort content that competence started looking suspicious. In 1999, the fear was that computers would get too good at pretending to be us. Now, someone writes a decent paragraph online, and half the replies treat it like evidence of a machine. The panic survived. The standards didn’t. A coherent … Read more

“AI-powered” is no longer a differentiator. As AI becomes commoditized, the winners will be startups that move beyond features and focus on clear positioning, strong category narratives, and customer-centric messaging. Growth in the AI era is driven less by technology claims and more by how clearly a company defines who it is for, what problem … Read more
