SCALA 3 MIGRATION: REPORT FROM THE FIELD

A developer migrated a large Scala 2.13 project to Scala 3, which was tough at first due to dropped features and lots of code changes. However, the migration was made easier by using IntelliJ's migration tools, using sbt source generators with Scalameta to replace lost macro annotation functionality, and finding workarounds for removed type projections.

AI MAKES TECH DEBT MORE EXPENSIVE

AI tools struggle to generate useful responses in codebases with lots of tech debt, such as those with subtle control flow, long-range dependencies, and unexpected patterns. This means that developers should prioritize refactoring legacy code into modular, well-defined units to take full advantage of AI.

UNDERSTANDING REASONING LLMS

There are four main methods for building reasoning models, which are LLMs that perform well on multi-step tasks. These methods are inference-time scaling (increasing computational resources during inference), pure reinforcement learning (RL), supervised fine-tuning (SFT) combined with RL, and knowledge distillation via SFT of smaller models. DeepSeek R1 models are a case study on the effectiveness of SFT+RL. Distillation is great for cost-effective model development.
