When I started learning Go, one of the first questions I had was: “How do I actually structure my code?” In languages like C, it’s common to throw everything into a single file, or maybe separate header and implementation files. But in Go, project structure is a big deal: it affects how easily you can … Read more

The contemporary discourse on data governance has been compromised by Data Idealism which approaches data as primarily a social and techno-legal artifact. There are variations of data idealism, such as data ethics, “Free Flow with Trust”, data decolonisation, data feminism, ethical AI development and others which basically suggest that much of the social, political, and … Read more

I once visited a data center in northern Virginia, a huge windowless building that looked like a fortress. Inside, it was incredibly noisy with thousands of servers running, cooling fans roaring, and backup generators on standby. The facility manager proudly told me that the building used as much electricity as a small city. “We have … Read more

The problem with centralized internet infrastructure goes beyond just service disruptions or high costs. Outages, censorship, and monopolies are major weaknesses in the global communication system that impact economic growth, democracy, and emergency responses. With 2.6 billion people still offline and current users facing more limits on accessing information, these issues become obstacles to human … Read more

How We Combined Vector Search, Knowledge Graphs, and Chain-of-Thought Reasoning to Build a Hallucination-Resistant Document Intelligence System We built a local-first RAG system that doesn’t just retrieve documents it validates responses using semantic similarity, critiques its own answers before returning them, and runs hybrid vector+graph retrieval in parallel. This article breaks down the architecture, shows … Read more

Regulation is a big obstacle to financial innovation, especially in digital finance, where technology moves faster than rules. Blockchain platforms like Gluwa push policymakers to find a balance between innovation and financial stability, consumer protection, and control over money. This challenge is clear in areas like cross-border payments, stablecoins, and blockchain credit systems, where old … Read more

Nearly 3 billion people still don’t have reliable internet, but satellite-based DePIN networks could help by using decentralized infrastructure and blockchain payments. I first wrote about global connectivity in 2020, looking at how the digital divide affects economic growth. This issue is still important because, despite years of investment in infrastructure, 2.6 billion people, or … Read more

Picture this: It’s 2045. You’re a mining engineer on a lunar base, and you need to transfer payment to a supplier on Mars for critical equipment parts. Your Earth-based bank account? Useless. Traditional internet? Laughably inadequate. The communication delay between Earth and Mars ranges from 4 to 24 minutes depending on orbital positions. Good luck … Read more

“I closed my last Chrome tab 6 weeks ago.” That’s what a product manager told me yesterday. Not because Chrome broke. Because something better finally exists. Let me tell you a truth most people haven’t realized yet: We’ve been trained to accept terrible browsing experiences because browsers were built for advertisers, not knowledge workers. You … Read more

If your AI startup fails, it is rarely because your model was weak. It is because your data backbone was fragile. You can build brilliant models and hire top engineers. But when messy real data, compliance rules, scaling pressure, and production drift hit you will see data failure first. I have studied dozens of AI … Read more

The Hidden Challenge Beyond the Prompt For the past few years, “prompt engineering” has dominated the conversation in applied AI. The focus has been on mastering the art of instruction; finding the perfect words and structure to elicit a desired response from a language model. But as developers move from simple, one-shot tasks to building … Read more

That game you paid 70 euros for? It’s not yours. That digital library you’ve built up over years of purchases? It’s just a long-term rental. We own a user license, a revocable permit that ties us to a platform’s decisions. If the store shuts down, if the publisher decides to pull a title, our investment … Read more

As an opinionated observer of the fintech space, I find Gluwa’s story a refreshing antidote to blockchain cynicism. It demonstrates that the oft-repeated mantra “blockchain will bank the unbanked” can be more than conference jargon; it can be a living, breathing solution deployed in the wild. Gluwa has proven that blockchain is more than just … Read more

Space tourism is no longer science fiction. Rocket engines roaring off launch pads, capsules flying through micro-gravity arcs and selfies taken from orbital windows are proof it’s real and growing. But flights that are treated as entertainment mask the vulnerabilities. Accidents during test flights, unstudied health effects, legal gaps and environmental harm show the frontier … Read more

Meanwhile, far away in … Read more

By 2026, startups will have a wealth of new tools for building apps. Low-code and no-code platforms offer visual, drag-and-drop interfaces that automatically generate application code. Low-code “enables automated code generation through visual building blocks” while still allowing custom scripting. No-code goes even further by eliminating manual coding, relying “100% on visual tools”. These platforms … Read more
