Feeling inspired to write your first TDS post? We’re always open to contributions from new authors.
There’s always something exciting and energizing in the air when we flip the calendar to September, and this year was no exception. Sure, bidding farewell to long sunny days and a slightly slower pace can make anyone a bit wistful, but not for long—not when there’s so much happening in the ML and AI scene, so many new tools and innovations to learn about, and lots of new skills to develop.
We’re thrilled to share our most-read and -shared articles of the past month in case you missed any of them (or just want to revisit a favorite or two). Even more than usual, they represent the full breadth of topics our authors cover, from core programming skills to cutting-edge LLM techniques, so we’re certain that you’ll find something in our September highlights to pique your interest. Happy reading, and here’s to a new season full of learning and growth!
