Golden Paths in IDPs: From Developer Chaos to Clarity

A new team spins up a service. They wire together a CI pipeline, stitch in some Terraform for infrastructure, and maybe β€” remember to add monitoring. Another team does the same, but with different tools, different conventions, and different assumptions. Fast forward a few months, and what was once a fast-moving engineering org is now struggling with undocumented know-how, snowflake pipelines, and production incidents...

8 Challenges in Multimodal Training Data Creation

Multimodal AI processes multiple forms of data, like images, sounds, and words, all at once, to empower your applications to not just listen to our voice or read text but also pick up facial expressions and the details around us. This technology is rapidly making our daily interactions easier and natural, and when using applications with which you can communicate, it feels almost as if you are chatting with your...

The Agile AI Manifesto

TL;DR: The Agile Manifesto Predicted AI The Agile world is splitting into two camps: Those convinced AI will automate practitioners out of existence, and those dismissing it as another crypto-level fad. Both are wrong. The evidence reveals something far more interesting and urgent: Principles written in 2001, before anyone imagined GPT-Whatever, align remarkably well with the most transformative technology of recent...

The childhood game that explains AI’s decision trees

An engineer recently explored how the classic board game Guess Who? reveals the underlying logic of AI decision trees. In the game, players don’t guess β€” they ask the question that gives the most information, systematically eliminating possibilities until only one remains. This mirrors how decision trees in machine learning split data: each β€œquestion” (feature) aims to reduce uncertainty and create cleaner partitions....

Pattern Searching and PostgreSQL Full-Text Search: Understanding the Mismatch

A while ago, a request emerged to implement a global find functionality in one of our products. Briefly, the purpose was to be able to search for multiple (different) entities by a pattern that is looked up and matched against several of their attributes. Not very complicated at first glance, such a feature comes with a lot of concerns and trade-offs that need to be analyzed, in addition to the implementation itself,...

Building Cost-Effective Internet Scale Applications

As developers, it is important that when we build an application, we design keeping both its targeted scale and the cost of running it in mind. If we are building an internet-scale application that could start from zero traffic on day one and gradually achieve a scale of millions of daily users, we have to choose a design and set of tools that can scale in a similar fashion. This is easier said than done. Developers...

Why Incomplete Documentation Is a Security Vulnerability in SaaS

Many SaaS teams pay more attention to encryption, firewalls, and compliance checks. They often overlook an essential asset: documentation. Documentations may not be as exciting as a new firewall or security tool. However, unclear, outdated, or incomplete setup guides, API references, and internal runbooks can lead to security gaps.

Dynamization of Static Data Structures

Most of us in software engineering have been there. You design a static data structure that supports blazing-fast queries for counting elements, searching patterns, or similar tasks. However, the moment you need to support insertions, performance collapses because rebuilding from scratch after every update is too slow. If you're lucky, you might find (or invent!) a different data structure which:

Master Developer Writing: From Docs and Pull Requests to Blog Posts

Developers are natural problem-solvers. We think in systems, patterns, and code. But one of the most underrated skills in a developer's toolkit has nothing to do with code; it’s writing. According to Atlassian’s 2025 State of DevEx report, developers lose an average of six hours per week due to poor documentation and organizational inefficiencies. That’s despite AI helping with productivity. The real bottleneck?...

Booleans vs Integers in Databases: Understanding the Trade-Offs

When designing a database, developers often encounter a seemingly simple decision: Should we use a boolean or an integer to represent a (decision) field? While the difference might seem trivial at first, the choice can have significant implications for storage, maintainability, and scalability. Let’s explore the pros and cons of each approach, with a focus on storage size, operational overhead, and long-term...

Smart Choices Between Inter- and Intra-GPU Communication

Why the Way GPUs Talk to Each Other Matters Imagine you’re back in school, working on a group project. Everyone in the group is smart and capable, but the project keeps dragging. Not because people don’t know the answers, but because they waste time passing notes around or waiting for someone else to finish. That’s exactly what happens with GPUs. These processors are incredibly powerful, but the way they communicate β€”...

Who Governs Your NHIs? The Challenge of Defining Ownership in Modern Enterprise IT

"Ownership" is one of the harder concepts to define in the modern enterprise. This feels deceptive because, from a personal and human level, ownership is a rather straightforward concept. When you own something as a person, like your car or your house, you control it completely, and you're accountable when things go wrong. Ownership means something fundamentally different for individuals than it does for enterprises,...

I pushed Python to 20,000 requests sent/second. Here's the code and kernel tuning I used.

I wanted to share a personal project exploring the limits of Python for high-throughput network I/O. My clients would always say "lol no python, only go", so I wanted to see what was actually possible. After a lot of tuning, I managed to get a stable ~20,000 requests/second from a single client machine. The code itself is based on asyncio and a library called rnet, which is a Python wrapper for the high-performance...
