Hey everyone! I just put out a video on Domain-Driven Design. It’s a long one, about 20 minutes, but I really believe it’s worth your time. It took me a lot of time to make, so I hope it helps you, and I’d love to hear what you think! 🙌

Learned Index Lab: Replacing B-Trees with streaming linear models in pure Rust (-99% RAM, 3x faster) (github.com)

143 · submitted 1 day ago by gilnett to r/programming

  • 45 comments

Instead of pointer-chasing through B-Tree node hierarchies, this index models the key distribution using streaming piecewise linear regression with strict epsilon error bounds.

Lookups compute positions directly on the CPU ALU before a local L1 cache search, reducing memory by 99% and cutting latency by 3x.

Where do you go for help when you're stuck now? Survey says 64% of developers visit Stack Overflow less for simple questions (stackoverflow.blog)

  • 13 comments

The 2026 Stack Overflow survey reports that 83% of developers search online for answers and 70% ask an AI agent, and 64% say they visit Stack Overflow less for simple questions.

When you're stuck as a learner, where do you start: search, an AI tool, a forum, a friend? Has the order changed in the past year, and what do you do to make sure you actually learn the answer?

Source (first comment): Stack Overflow 2026 survey post. Opened and verified: 83%, 70%, 64%.
