Built on PyTorch, Ray, SGLang, and NVIDIA Megatron-LM, Miles is an open source framework from RadixArk for large-scale LLM reinforcement learning post-training. Miles uses PyTorch for models, numerics, profiling, and extensibility; Ray for orchestration; SGLang for rollout generation; and Megatron-LM for distributed training. The framework supports asynchronous rollout and training, NCCL/RDMA weight synchronization, MoE-aware rollout/training alignment, low-precision recipes, LoRA, fault tolerance, observability, and extension points for custom algorithms and model architectures. 🔗 Read more in our latest blog from the Miles Team:

New course: Efficient Inference with SGLang: Text and Image Generation, built in partnership with LMSys @lmsysorg and RadixArk @radixark, and taught by Richard Chen @richardczl, a Member of Technical Staff at RadixArk. Running LLMs in production is expensive, and much of that cost comes from redundant computation. This short course teaches you to eliminate that waste using SGLang, an open-source inference framework that caches computation already done and reuses it across future requests. When ten users share the same system prompt, SGLang processes it once, not ten times. The speedups compound quickly, especially when there's a lot of shared context across requests. Skills you'll gain: - Implement a KV cache from scratch to eliminate redundant computation within a single request - Scale caching across users and requests with RadixAttention, so shared context is only processed once - Accelerate image generation with diffusion models using SGLang's caching and multi-GPU parallelism Join and learn to make LLM inference faster and more cost-efficient at scale!

Fixed this small bug in Linear’s app today which I often see in other apps as well. Here’s a small before/after. The issue: When you open a popover inside a modal (think a custom select), clicking outside the popover to close it also closes the modal. The desired behavior is to close the select on click outside while keeping the modal open. This often happens because custom dropdowns or select components are rendered in a portal. The modal then treats the interaction as an outside click because, technically, the dropdown isn’t inside the modal in the DOM, it’s rendered elsewhere via a portal. The fix depends on your setup, whether it’s Radix/Base UI, fully custom etc. But since you now know the cause of it, you can ask your agent to fix it for you!

What motivates @KentBeck after 40+ years in software? Veteran creator of TDD, XP, JUnit and co-author of the Agile Manifesto, on what drives him to keep going: #1# - He’s not afraid to start new things “If there's a secret sauce to what I'm doing, it's not being afraid to start over. Look on my GitHub, you'll see project 1, project 2, project 3 and so on. I'll push it a certain amount, and then “the genie” runs itself out of options. It can't make further forward progress, and so I'll wipe it away. Start over. I won't try and tweak it." #2# - Coding with the AI “Genie” has brought back Kent’s creative impulse "That creative impulse is what's come back to me with 'the genie'. I can go, I wonder what a B+ tree looks like - and go, oh, here's an alternative, this adaptive radix tree. What does that look like? I can find out. I sit down with the genie, I work it out, and then there's this artifact that wasn't there before. That's there now because of my imagination and my work. I had gotten fed up with the stupid minutiae of programming." #3# - Kent has FORTY years worth of ideas to build out: “I've got 40 years worth of ideas that suddenly are back in play and I'm having so much fun making things that are real.”
