Ask HN: What apps / platforms inspire you? Who do you learn design from?
I'm trying to get better at design, which is really challenge for someone like me with limited aesthetic sense. It really helps to learn by example -- by studying what others have done. Most of the "Design Inspiration" websites seem to be aimed at marketing type sites, but I'm really looking for application or platform design inspiration. This is a community of builders who build just those types of platforms, so it's a logical place to ask:
Which apps, websites, or platforms do you look to for design inspiration? Who do you think really nails both user experience and visual design? Which platforms manage to both look beautiful and work great?

Show HN: LeanRL: Fast PyTorch RL with Torch.compile and CUDA Graphs
We're excited to announce that we've open-sourced LeanRL, a lightweight PyTorch reinforcement learning library that provides recipes for fast RL training using torch.compile and CUDA graphs. By leveraging these tools, we've achieved significant speed-ups compared to the original CleanRL implementations - up to 6x faster!
Reinforcement learning is notoriously CPU-bound due to the high frequency of small CPU operations. PyTorch's powerful compiler can help alleviate these issues, but comes with its own costs. LeanRL addresses this challenge by providing simple recipes to accelerate your training loop and better utilize your GPU.
Key results: - 6.8x speed-up with PPO (Atari) - 5.7x speed-up with SAC - 3.4x speed-up with TD3 - 2.7x speed-up with PPO (continuous actions)
Why LeanRL?
- Single-file implementations of RL algorithms with minimal dependencies in the spirit of gpt-fast - All optimization tricks are explained in the README - no heavy doc, just simple tricks - Forked from the popular CleanRL library
Check out LeanRL on https://github.com/pytorch-labs/leanrl now!
