The concepts of "topic" and "subscribe" are often linked, especially in contexts like messaging systems, event-driven architectures, or content platforms. Publisher: This is the source or entity that produces messages or events. The publisher doesn't need to know who will consume its messages. Topic: This acts as a channel or intermediary that categorizes messages. Publishers post messages to specific topics, and...

Scalable Distributed Architectures in E-Commerce: Proven Case Studies
Modern e-commerce platforms must handle massive scale β from flash sales driving sudden traffic spikes to global user bases demanding low-latency experiences. Achieving this reliability and performance at scale requires robust distributed architectures. In this article, Iβll share three case studies of scalable e-commerce architectures that Iβve analyzed and worked with, each leveraging a different tech stack:...
Create Your Own Custom LLM: Essential Steps and Techniques
We will start by defining the most fundamental building block of LLMs: Language modeling, which dates back to early statistical NLP methods in the 1980s and 1990s and was later popularized with the advent of neural networks in the early 2010s. In its simplest form, language modeling is essentially about learning to predict the next word in a sentence. This task, known as next-word prediction, is at the core of how LLMs...
Estimating Software Projects: A Practical Approach for Tech Leads
Introduction Accurately estimating software projects has been a big challenge for technical leads for quite some time. While there are many established techniques in the market that explain how to estimate a task at hand, they donβt often provide a systematic process to break down tasks, account for unknowns, and track and revisit the estimates. In practice, estimation is an ongoing exercise that keeps evolving with...

Built an open-source automation framework for OSRS - Here's what I learnt
To preface: OldSchool RuneScape is a popular MMORPG that I don't have the time to play anymore, so I'll make a robot to play it for me, without getting banned. After spending a couple months messing around with a couple botting utilities and talking to many experienced devs, I noticed that many people get banned because they use the same script and therefore share a fingerprint. So I built my own framework from the...
Why Developers Should Pay Attention to Internal Directory Security
Most developers donβt start their day thinking, βIs our internal directory secure?β Theyβve got builds to run, bugs to squash, maybe a pull request or five to review. But internal directories (like Active Directory or Azure AD) arenβt just a concern for IT admins. Theyβre the nervous system of any organization with more than, say, a handful of people and passwords.
WebAssembly: From Browser Plugin to the Next Universal Runtime
For decades, the digital world has converged on a single, universal computing platform: the web browser. This remarkable piece of software, present on nearly every device, promised a "write once, run anywhere" paradigm, but with a crucial limitation, it only spoke one language natively: JavaScript. While incredibly versatile, JavaScript's nature as a dynamically typed, interpreted language created a performance...

Is Your Team AI-Ready? 5 Strategies to Upskill Your Engineers
The pressure is on. Every leader, from startups to Fortune 100s, is being asked the same question: "What's our AI strategy?" But behind that question is a more fundamental one that keeps engineering leaders like us up at night: "Is my team ready for AI?" Itβs one thing to buy a new tool or spin up a new service; itβs another thing entirely to transform a teamβs skills and mindset. The truth is, most engineering teams...
Chrisβ Corner: Scroll-Driven Excitement
Scroll-Driven Animations are a bit closer to usable now that Safari has them in Technical Preview and Firefox has them behind a flag. Chrome has released them.

Fine-Tuning LLMs Locally Using MLX LM: A Comprehensive Guide
Fine-tuning large language models has traditionally required expensive cloud GPU resources and complex infrastructure setups. Apple's MLX framework changes this paradigm by enabling efficient local fine-tuning on Apple Silicon hardware using advanced techniques like LoRA and QLoRA. In this comprehensive guide, we'll explore how to leverage MLX LM to fine-tune state-of-the-art language models directly on your Mac,...
Deep Observability in Node.js Using OpenTelemetry and Pino
As applications become increasingly distributed, debugging performance issues or locating failures in a Node.js backend can be challenging. Logging by itself usually provides limited context to comprehend how a request navigates through many layers of your system. Similarly, you cannot correlate trace data with application-specific events if you use tracing without structured logging. That is where OpenTelemetry (OTel)...
Cross-pollination as a strategic advantage for forward-thinking organizations
Innovation is at the heart of any successful, growing company, and often that culture begins with an engaged, interconnected organization.
AI for AI: How Intelligent Systems Are Shaping Their Own Evolution
AI for AI, also referred to as AI4AI, is a rapidly growing field that focuses on using artificial intelligence to improve the development, performance, and management of other AI systems. It involves applying AI techniques to automate and optimize various stages of the AI lifecycle, including model selection, training, deployment, and ongoing adaptation. This approach enables AI systems to operate more autonomously and...

Beyond 200 OK: Full-Stack Observability for Developers
You may remember coming out of a feature meeting and saying to yourself, "My React frontend is working fine, the API goes 200 OK, I am done!" Then, a few days later, we get a user complaint: "It's slow. Sometimes I get errors."
How to Build an MCP Server With Java SDK
A previous article [Resource 1] described how an open-source PostgreSQL Model Context Protocol server can be plugged into an AI host and provide additional database context to the interacting LLM. Moreover, quite a few interesting insights on the considered data were inferred by the LLM when natural language prompts were written and responded to. The current article uses the exact same database schema and does a...
Real-Time Flight Schedule Changes at Scale: Event-Driven Pipelines With gRPC
Introduction: The Challenge of Flight Schedule Changes Travel aggregators (like online travel agencies or fare comparison platforms) handle data from hundreds of airlines, including frequent flight schedule changes β delays, cancellations, gate changes, etc. Managing these updates in real-time for millions of users is a massive challenge. Traditional approaches (like periodic polling or manual updates) canβt keep up...

The State of Software Development in 2025
84% of engineers use or plan to use AI tools (up from 76% in 2024). This has been an interesting insight from the Stack Overflow 2025 Developer Survey that I have closely looked at. Some other interesting insights: Trust in AI accuracy worsened -> 46% of engineers now distrust AI outputs (versus 31% in 2024) Experienced engineers are the most skeptical -> only ~2.5% highly trust AI, and 20.7% highly distrust it...
Posted a couple of weeks ago about progress I had made building a minimal FAT32 file system driver. I have now finished my prototype in Python and am working to port it to #[no_std] Rust to use on an embedded platform. Having lots of fun with this deep dive! Hope someone gets something from this!
Meta comment, I've never written tests for any personal project ever before, but doing some TDD actually really helped me with this. You can find the code here: https://github.com/careyi3/fat32py submitted by /u/careyi4 [link] [comments]

Snob: a picky test selector for python π§
Most of the time, running your full test suite is a waste of time and resources, since only a portion of the files has changed since your last CI run / deploy. Snob speeds up your development workflow and reduces CI testing costs dramatically by analyzing your Python project's dependency graph to intelligently select which tests to run based on code changes. submitted by /u/damien__f1 [link] [comments]
