Hackernoon

Most people think cybersecurity is a visual field. They imagine glowing monitors, endless terminal windows, lines of code scrolling across multiple screens, analysts staring at dashboards, and hackers tracking packets in dark rooms illuminated by LEDs. I cannot see any of that. I am completely blind. And yet, cybersecurity became my life. My name is … Read more

AI is not a great equalizer. It is a great amplifier. It amplifies what you already are — for better and for worse.

Now remember how PCA collapses data with 100 dimensions into a single dimension, wouldn’t it be cool if this dimension was interpretable. For example, let’s say the 100 columns were like stress, smoking frequency, alcohol ml etc etc.. you see where I am going with this, the final dimension would be something like cardiac arrest … Read more

For most people, the US immigration system feels like a black box. You submit documents, you wait and you hope. The rules shift without warning. The timelines stretch. The costs climb. And if something goes wrong, figuring out why can take months and thousands of dollars in legal fees. Swatilina Barik decided that did not … Read more

There is an entire category of commercial enterprise whose business model consists of hunting down small website operators and locating images of questionable or marginal legal exposure. These companies then threaten operators with financial demands that bear no rational relationship to any actual harm suffered, despite the fact that in the overwhelming majority of cases … Read more

Maybe you already know what AI is. But then your manager, a friend, or your mom asks you to explain it, and suddenly it becomes harder than expected. This article is my attempt to explain AI in plain words — the way I would explain it to someone who does not care about tokens, weights, … Read more

When you estimate in complexity, the conversation is about the problem. Why is this a 5 and not a 3? What’s hiding inside it? What risks does it carry? Juniors learn by watching seniors reason. Seniors sometimes realize the “trivial” thing wasn’t trivial. The team understands what they’re about to do — together — before … Read more

Using AI in a language I barely know wasn’t impressive. It was revealing. It showed me very clearly what parts of my skillset are portable — and what parts aren’t.

What does a concert ticket actually say about who you are when 96 out of every 100 people in the queue are not people at all?

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.

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

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
