A Brief History of HTTP

HTTP has continuously evolved since the founding of the Internet in 1989. The first RFC document published by the Internet Engineering Task Force (IETF) appeared in 1996. Let’s trace the history of HTTP over the years up to June 2022, when a new series of RFC documents was published standardizing HTTP/1.1, HTTP/2, and HTTP/3.

Platforms, Teams, and APIs: How Do They Fit Together?

One of the major trends in recent years has been Platform Engineering, as many organizations strive for more efficient and fasterdevelopment practices. The term has gained traction since 2018, particularly following an influential article by Evan Bottcher. Looking at the origins of this concept provides valuable insights into the relevance of Platform Engineering today and its potential future developments.

RAG: The Architecture of Reliable AI

How can we ensure that AI systems are precise, transparent, and always up to date? All Large Language Models (LLMs) have a cut-off date where their world knowledge ends. And they know nothing about your company’s internal information. Even the leading models still have hallucination rates we can’t completely ignore. Yet they offer enormous potential for productivity, efficiency, and creation. Retrieval-Augmented Generation (RAG) addresses exactly this issue: LLMs are enhanced through targeted information retrieval.

Document Ingestion

How can we transform a pile of diverse documents into a high-quality knowledge base for AI systems? Document ingestion is the critical first step in any Retrieval-Augmented Generation (RAG) system—and often the reason why these systems fail.

Implementing GitOps without Kubernetes

“GitOps only works with Kubernetes as the operating platform!” This persistent misconception about GitOps might explain why it hasn’t become a standard workflow tool for software delivery yet. Most available GitOps tools require Kubernetes. However, GitOps fundamentally means using a version control system (VCS) like Git as an interface for a software agent to handle deployment and operational tasks within a target environment.

When the Worldview is Shifting

Large Language Models (LLMs) can feel like magic. We observe them and imagine that they work in a certain way. Then something surprises us, shattering the illusion and fundamentally reshaping our understanding. In this blogpost I’ll show you one such surprise from my own experience, and I believe that your worldview will have changed at the end.

LLM-assisted Abbreviation Mining for Legacy Systems

This blog post shows the process of mining abbreviations and discovering first concepts a COBOL legacy mainframe codebase is made of with the help of Large Language Models. It uses Python, pandas and Claude 3.5 Sonnet to generate insights that can be gathered from such a simple thing like a list of files.

Type-safe SQL queries in Java and Rust

In recent years, our industry has been in favour of strong typing and build-time verification to make certain classes of bugs impossible. How much influence has this trend had on how we can write SQL queries in Java? Let’s look at how typesafe SQL queries can be in Java, how this compares to what you can do in Rust, and consider the benefits and drawbacks of these different approaches.

One of the main tasks that business sets for IT as an industry is the creation of effective software, according to criteria that clearly meet the needs of this business. On the other side, one of the main prerequisites for achieving the goals that a business sets for itself is the ability to hire specialists who can create a product in the shortest possible time and/or effectively maintain it. Accordingly, to achieve this, the technology stack used, i.e. tools, must be mature enough, and widely used in the market.
