A package appears in a registry. The name looks familiar. The version number is plausible. The install script runs before anyone reads the code. That’s not a vulnerability. That’s a trap. Software Composition Analysis was initially invented as a way of detecting any existing CVEs present within packages. This task remains critical for ensuring application … Read more

A realistic phishing simulation should resemble a decision the employee might actually face. A payroll change is relevant to HR. An unfamiliar repository invitation fits an engineering workflow. A supplier’s payment request matters to finance. Realism depends on the request, the recipient’s responsibilities and the safe action they are expected to take. This shortlist compares … Read more

A website can reveal very little about its operator while still carrying the advertising infrastructure that helps it earn revenue. For investigators examining a domain that rehosts content or is suspected of fraud, that infrastructure offers another place to look when the site itself provides few useful ownership details. Advertising identifiers, the identifying values associated … Read more

Building a Bible app taught us a fundamental product truth: pure software is passive—it waits for you to open it. But life, anxiety, and physiological stress happen in real time. Here is why we built a smart ring to bridge that gap. An app on its own is inherently passive: it has to wait for … Read more

The receipt you never get when a server tells you which model answered, how would you know? Today you would not. An API response has a model field, and that field is a string the provider typed. You cannot see the weights, the quantization, the system prompt, or whether your request was cached, rerouted, or … Read more

Initial Notes This type of article is, as far as I know, one of the first of its kind. I couldn’t find any article that goes deeply into the technical side of this type of vulnerability. There have been some vulnerabilities discovered around the same topic in 2026, according to the CVEs I found, which … Read more

TL;DR: Every leap in LLMs, from GPT-1 to today’s agents, came from changing one thing: what the model is trained to do. Next-token prediction gave models knowledge. Post-training made them assistants. Reinforcement learning made them reason. Tools made them agents. Underneath it all, the real engine is data designed to teach the right objective. Every … Read more

A few years ago, I worked on a problem in Apache Fineract (an open-source platform for building financial services and core banking systems) that sounds simple until you start looking closely at it: when a borrower makes a payment, exactly where should that money go? To solve this problem, I designed the Advanced Payment Allocation … Read more

You have a new prompt, model, or orchestration policy. Offline tests look good, but the change will see vocabulary, timing, and context combinations that your fixture set never captured. So you shadow-test it: send production traffic to both the current agent and the candidate, compare their decisions, and keep the current agent in control. Then … Read more

The term second brain is not new. For years, people have used it to describe the habit of collecting notes in an app, tagging them, and searching for them when needed. That is how I began, too. These approaches have one thing in common: a person puts things in, and a person looks for them. … Read more

Organizations want to react to transactions as they happen, detect anomalies before they … Read more

A model is a dependency, I ship software that depends on model weights. When I pin a version of a library, I expect the same bytes tomorrow.

The smallest game worth architecting: an immutable board, testable rules, a view that just renders state, and the classic AI you can bolt on in 40 lines Tic tac toe is the “hello world” of game development, which is exactly why it’s worth doing properly.

I run a small bilingual tutoring site, Intellix Tutoring. It is static HTML built with Jekyll on GitHub Pages: 68 pages, half in English and half in Italian, on a domain registered at the end of May.

Key Takeaways Synchronous webhook to runner systems do present some issues but we see that they are at risk for certain problems. The solution isn’t to add more runners, instead what we do is we separate input functions from processing via the partitioned event bus.

Key Takeaways GoldenGate lag is not one number but the sum of waits in a chain of queues, and the fix depends entirely on which queue is growing.
