From Big Data to Agents: My Decade Building Systems

When a Simple Scraper Changed Everything My first “real” task wasn’t glamorous: scrape some data. We all start at the bottom, and scraping is a rite of passage for data engineers — turning unstructured sources into structured signals. That first job taught me a lesson I’ve carried since 2014/15: access to the right data beats cleverness — and the right pattern beats the shiniest tool. Looking back at that moment — and...

Testing Updates in Insert-Only Ledger Tables and Understanding Updates in Updatable Ledger Tables

In SQL Server, ledger tables offer powerful tamper-evident functionality, which is essential for systems that require high levels of trust and auditability. Two distinct types serve different needs: insert-only ledger tables and updatable ledger tables. Insert-only tables enforce strict immutability, allowing data to be added but never altered or deleted, making them ideal for transaction logs or event sourcing....

Building a Scalable and Reliable Marketing Data Stack on GCP

Creative campaigns are no longer modern marketing; data is. And not any data: clean, contextual, and timely data that fuels specific, personalised experiences that enable quantifiable outcomes. If you have dozens (or hundreds) of campaigns running across platforms such as Google Ads, Meta, and programmatic DSPs, the infrastructure that enables this orchestration is just as important as the insights themselves. Today,...

Unpack IPTables: Its Inner Workings With Commands and Demos

We all know that the internet works by sending and receiving small chunks of data called packets. Back in the early days, when the internet was still in its infancy, packets were allowed to transfer freely across a connected world, however small that world was. Anyone could send packets to your system, and you could send packets to other connected systems. All services running on systems were exposed by default. As the...

Implement a Circuit Breaker for an Unavailable API Service Running in App Connect on CP4I Using Red Hat Service Mesh

Some applications may not respond during heavy load. These outages are due to out of memory and high CPU utilization when many requests are piled up at the application entry point since the back end is not available. In this article, we will solve this problem using Red Hat OpenShift Service Mesh, which provides a way to stop sending requests to the application or API if it is unhealthy. This article shows how to...

Bounded Rationality: Why Time-Boxed Decisions Keep Agile Teams Moving

In Agile projects, decisions come fast and often: Which story should we pull next? Is this bug critical enough to stop the sprint? Do we ship the feature now or wait for another test cycle? Every time a Scrum team stops to analyze, debate, or wait for more data, the sprint clock keeps ticking. Delays accumulate — missed commitments, context switching, and mental fatigue ensue.Bounded Rationality, a concept introduced...

From Keywords to Meaning: A Hands-On Tutorial With Sentence-Transformers for Semantic Search

Traditional keyword-based search systems are inherently limited, as they operate on exact word matching rather than contextual understanding. For instance, a query such as “physician appointment” may fail to retrieve results containing “doctor visit”, despite their semantic equivalence. Recent advances in natural language processing, particularly through sentence transformers, address this gap by generating semantic...

Patterns for Building Production-Ready Multi-Agent Systems

The Problem: When One Big Model Falls Short Imagine you’re building an AI assistant that’s supposed to handle everything: answer customer questions, do research, write code, plan schedules, all in one go. Very likely, it will start to fall apart when things get more nuanced and complex. A single model that tries to be a jack-of-all-trades often becomes master of none. And if you need to update or improve one aspect of...

In 1989 development began on an interpreter and in 2005 the project was released as open source. Since then it is improved on a regular basis. Seed7 is about maintainability, portability, performance and memory safety. There is an automatic memory management, but there is no garbage collection process,...

How Laravel Developers Handle Database Migrations Without Downtime

Database migration is a normal, albeit crucial, task when working with Laravel applications. Database schema will be updated in this process; new columns might be added, indexes might be changed, and the table itself might be modified, all to accommodate new features or improvements in the baseline code. But database migration in a live production application is inadvisable since doing migrations can lead to...
