Moving AWS Glue jobs to OCI Data Flow: a working map
26+ min ago (294+ words) If you run Spark ETL on AWS Glue and need to move it to Oracle Cloud, the good news is that most of it maps cleanly. The bad news is the few parts that don't, and they are exactly the…...
Rule-based systems and machine learning aren't as different as people make them sound.
44+ min ago (293+ words) I started Module 1 of #MLZoomcamp by Alexey Grigorev this week, and two things clicked for me. First: a rule-based system is code you write that produces an outcome. You look at spam emails, notice patterns, and hardcode them: sender is…...
Hard Negative Mining: Teaching an LLM What "Almost Right" Looks Like

Why Top-Down Truncation Breaks AI Agents (And How Even-Span Fixes It)
2+ hour, 15+ min ago (146+ words) Most AI coding context generators have a hidden design flaw: they truncate long files sequentially from line 1 downward until they hit a token budget limit. If a file has 1,200 lines and your budget allows 400 lines, the model receives lines 1 to…...
Stop Using 2,000ms LLMs for Simple Choices: Introducing Laya (
2+ hour, 13+ min ago (127+ words) Every day, developers wire up massive generative Large Language Models (like GPT-4o, Claude 3.5, or Gemini) to make simple classification decisions: To solve this, I built Laya AI Decision Gateway. Instead of generating text, it maps inputs into high-dimensional vector spaces…...

Julia 1: A 144M-Parameter Decision Model Trained for $104
2+ hour, 42+ min ago (838+ words) A small AI lab in Brazil just released a model with an unusual claim. Not "beats GPT." Not "agentic superintelligence." The claim is this: a 144.3-million-parameter model that picks the right answer from a list you give it, runs on…...
