A week ago, OWASP released the first version of their Top 10 for LLM Applications 2026 whitepaper. My first thought: finally — an official, comprehensive recommendation on AI security. What is it? The OWASP Top 10 for LLM Applications 2026 is a guide to the most critical security risks facing applications powered by large language models. Think of it as the classic OWASP Top 10 for web security — but built specifically for the AI/LLM era. ...

Nowdays I am often surprised to find that team members pass sensitive data directly to AI agents exactly as it is. I believe that in the AI ​​era, handling PII within spreadsheets is more important than ever. What is PII? Personally Identifiable Information (PII) is information that can be used to distinguish or trace an individual’s identity, either alone or when combined with other information that is linked or linkable to a specific individual. ...

I’ve just published my new official WordPress plugin: VerCheck API. It’s a small, practical REST API plugin that exposes your WordPress installation’s version data over HTTP — so you can query it from anywhere without logging into the admin dashboard. What problem does it solve? If you manage more than one WordPress site, keeping track of outdated core versions, plugins and themes gets tedious quickly. Without having WP-CLI you have only a few options. The WordPress dashboard only helps if you’re already inside it. So if you’re running on shared hosting, tools like WP-CLI are often unavailable and that’s a problem. ...

The fundamental problem was the sheer volume of news in the world. Keeping up with it daily took up a lot of time, yet I still wanted to stay informed. My solution was to track the most popular news stories using Google Trends and have AI read and summarize them. Every day at noon I receive a summary of the top 10 latest stories, complete with links to the original articles should I wish to read further. This way I cut down on “mental junk food” — managing the flood of clickbait and fake news — while staying up-to-date using trending data. ...

Recently I’ve created a BigQuery related Python package: python-bigquery-migrations. It’s a lightweight CLI tool that brings database-style migrations to Google BigQuery — so you can create, version and manage your datasets and table schemas the same way you manage your application code. What problem does it solve? If you’ve ever worked on a project where BigQuery schemas were created by hand, copy-pasted between environments, or documented only in someone’s head — you know how quickly things go wrong. There’s no consistent way to track what changed, when, and why. ...

In this advanced level guide I’ll introduce how to create & run multiple Server-side GTM Unit Tests. I will share some practical tricks with examples on how to overcome unexpected challenges when your Custom Client Template Unit tests try to claim the request right after each other when we run them in batch. For the better understanding, I’ve wrapped the technical parts in a fictional business story. If you’re not interested in the story nor the planning or custom client coding part jump right to the section on Testing: Unit Testing our Client Template. ...
