Hackernoon

I was not inspecting bridges that morning. I was just trying to get to our construction technology lab in Jabi. It was the rainy season. The taxi from Lugbe couldn’t take me all the way, so the driver dropped me on the bridge at the Area 1–Airport Road interchange. From there, I walked down the … Read more

Introduction: Moving Beyond Static Masking Data protection is not a one-size-fits-all problem. When I first started implementing data redaction, the options were limited. Full redaction replaced everything with zeros or spaces. Partial redaction let you expose some characters and mask others. Random redaction generated unpredictable values. These worked for basic use cases, but they fell … Read more

If someone had told me five years ago that I’d be spending my Tuesday afternoons fine-tuning index pages for Euclidean distance calculations, I would have laughed them out of the data center. Yet, here we are. The explosion of generative AI, semantic search, and hyper-personalized recommendation engines has pushed the “similarity query” from a niche … Read more

AI-related securities class action filings more than doubled in a single year, from seven cases in 2023 to fifteen in 2024, according to Cornerstone Research and Stanford Law School. By 2025, that number kept climbing. In April 2025, one of those cases got a face. The SEC and DOJ charged Albert Saniger, founder of the … Read more

Are You Building a Company, or Grooming One to Sell? Two founders run companies in the same office park. Same headcount, same coffee machine, same Monday-standup energy.

Let me begin with what GTA 6 is not, because almost everyone online is preparing to sell you the wrong story without first checking whether the claims are even credible. One thing already looks clear: if you are expecting NPCs with some revolutionary next-generation brain, forget it. The people wandering through Vice City will still … Read more

Disclosure: I built and maintain the open-source tool discussed in this article. It is MIT-licensed and free. My coding agent can quote any file in my repo. It can search the web, hit APIs, and refactor a module while I get coffee. Ask it “what was I working on before lunch?” and it has nothing. … Read more

Style errors double when nobody enforces them. TL;DR: Wire your standards into hooks, skills, and a judge, so the harness blocks violations before a human opens the diff. Common Mistake ❌ You paste your coding standards into AGENTS.md and trust the AI to remember them. Then a human reviewer manually checks naming, indentation, and spacing on every pull request. Nobody wires a … Read more

Introduction In a previous article, I described building an agentic search framework in Go. While that architecture handled the functional requirements well, operating it at scale revealed significant cost and latency challenges. At millions of queries per month, LLM API costs, and P95 latency approached 5 seconds. This article presents the semantic caching architecture we implemented to address these issues. The system reduced … Read more

Overview OpenAI has publicized a limited preview of its GPT-5.6 model family, which contains three models (Sol, Terra, and Luna) that will allow users and developers to select based on intelligence, speed, and price. The Three Models GPT -5.6 Sol (the flagship model) is identified by OpenAI as the most powerful version released thus far, with its … Read more

The creator economy is buzzing with an exciting and empowering trend: combining a headless CLI like Claude Code, an Obsidian vault, and some clever markdown files to build a personal “Agent OS.” It is an incredibly accessible way to achieve a massive productivity boost, giving developers and creators a tactile, 24/7 autonomous assistant running right … Read more

Models generate code. Harnesses turn that output into reliable, repeatable, and governable delivery. AI agents create local speed; harness engineering turns that speed into dependable software delivery. A harness combines context, skills, tools, permissions, verification, and feedback. The goal is not to give agents unlimited autonomy. It is to make correct work easier and unsafe … Read more

Introduction The Floyd-Warshall algorithm is a foundational tool in graph theory, designed to find the shortest paths between all pairs of vertices in a weighted graph. Unlike algorithms like Dijkstra’s, which focus on single-source shortest paths, Floyd-Warshall operates globally, considering the entire graph at once. A common misconception is that the algorithm assumes paths are … Read more

Introduction: The Rise of Linux Linux has officially won. Not in the abstract, ideological sense, but in the tangible, mechanical way that systems either work or fail. By June 2025, the process was complete: Apple’s announcement of OCI-compatible container support and Microsoft’s native containerization in Windows 11 marked the final steps in Linux’s integration into … Read more

When a RAG system gets it wrong, the model is usually innocent. It answered faithfully from the wrong context. The bug is upstream, in a retrieval layer nobody bothered to measure. The bot cited a real document and was still wrong A support assistant I was helping debug confidently answered a billing question, and it … Read more

Know who speaks before the skill runs TL;DR: Always define a clear role at the top of every skill file so you know whose perspective drives the execution. Common Mistake ❌ You write a skill full of rules but assign no role. The AI starts executing without knowing if it’s a junior developer, a seasoned … Read more

In March I published a piece arguing that AI agents don’t have identities and that this was already a security crisis. The claim was operational. We were deploying systems that read files, call APIs and chain tools together, while the answer to the most basic security question, who exactly is acting right now, was still … Read more

It’s been a couple of weeks since Supergirl was released, and its box office run has been underwhelming to say the least. Deadline believes the movie could lose about $125 million.

For most of its history, cybersecurity has been a contest between human attackers and human defenders, throttled on both sides by how fast people can work. That throttle is gone.
