The compiler was never what you wanted

You have an orders topic on a Kafka cluster, its values encoded with Avro against a schema in the Schema Registry. You want the orders worth more than fifty euros on a topic of their own, and you have decided to do it with Kafka Streams — a JVM library, your code, your deployment. The schema has fi

Does That "Free Online PDF" Tool Upload Your File? How to Tell.

Most free online PDF tools work by uploading your document to a server, processing it there, and sending it back. For a lot of files that's fine. For a signed contract, a payslip, a medical form, or a scanned ID, it's the entire privacy problem: your document now lives on someone else's machine, sub

AI Engineering Is Easy. Changing How We Work Is Hard

AI engineering sounds fancy. New terms are everywhere: agentic development, AI-native engineering, spec-driven development, and now AI harness engineering. Underneath all the terminology, though, something genuinely useful is happening. AI can now help with requirements, challenge a PRD, explore UX

I Like Carbon-Aware Pricing, but I Would Not Let It Drive Production Yet

I stumbled across Carbon-aware electricity pricing during a break and ended up poking at it far longer than planned. The idea is simple but useful: track daily electricity pricing across 38 grids so engineers can think about when workloads run, not only how much compute they consume. That distincti

Building AI Agents That Actually Work: What Nobody Tells You

I've been building AI agents for a while now. Not chatbots. Not RAG demos. Real agents that take actions, make decisions, and run autonomously. Here's what nobody tells you. The gap between demo and production Every AI agent framework shows you a 5-line demo that works perfectly. Then y

How does one approach towards machine learning?[D]

Building a Web Development Workbench for Unitree G1 with C++17, SDK2 and WebSockets

I’ve been building UniRoboGui, an open-source browser-based development and debugging workbench for the Unitree G1 EDU. GitHub: https://github.com/ershui2500/UniRoboGui The main idea is simple: keep the robot-facing stack in C++17 on the G1 PC2, communicate directly through Unitree SDK2 DDS, and

10,000 Agents, Zero Tokens: Why the Best AI Architectures "Skip" the LLM

1. Introduction: The Scalability Paradox of Agentic Systems In the boardroom, AI agents are promised as the ultimate workers—autonomous, reasoning, and tireless. In the engineering trenches, however, we face a brutal scalability paradox: the more agents you deploy, the slower, more expensive, a

Running the WUIC assistant on a local LLM: Ollama, an MCP server, and a free agentic VS Code

Our in-product RAG chatbot has two halves. The first is retrieval — hybrid BM25 + bge-m3 + a fine-tuned reranker, running locally as native .NET/ONNX, with zero API surface to anyone. The second is generation — turning the retrieved chunks into an answer, or into a proposed metadata change. That sec

FreeLLMAPI: One OpenAI-Compatible Endpoint for 34 Free LLM Providers

Magento 2 Frontend Performance: Web Fonts, Critical CSS and Render-Blocking Resources

Migrated 42 workflows from Zapier to self-hosted n8n on Hetzner ($248/mo down to $7.70/mo)

Got tired of getting billed every time a Zapier polling trigger ran just to find zero new rows. Last week I finally bit the bullet and migrated all 42 of our workflows over to a self-hosted n8n instance. The cost difference is honestly ridiculous: Before: - Zapier Pro: $89/mo - Make Pro: $159/mo - T

The request we could not follow across four services

A customer sent us a screenshot of a 500 error with a timestamp. That was all we had. The request had passed through an API gateway, an auth service, an orders service, and a payments service, and each of them logged beautifully in its own format, into its own index, with no shared identifier anywhe
