Crypto traders will spend months chasing tiny edges in the market… while ignoring the fees slowly draining their portfolio in the background. 👀 The easiest way to improve returns might not be trading better. It might just be stopping the leak. 20% off Coinbase One + $50 BTC 👇

The 8-direction Sobel templates are convolution kernels used for edge detection in digital images. 3×3 convolution kernels for detecting edges in 8 different directions (0° to 315° at 45° intervals). Top row: 0, 1, 2 direction Middle row: 3, 4, 5 direction Bottom row: 6, 7 direction Right panel shows the corresponding edge direction numbering.

Just started testing the @grok Build beta. First feel: UX is nice, still some rough edges, but model speed is genuinely cool. If task quality on hard stuff matches opus 4.7 (or even slightly below) at this speed, it's a game-changer. Good chance they steamroll the competition.

hermes agent is already the best on local models. but i'm working on more edges to make it fly even harder. before that, if your agent keeps crashing on local inference here's what to check: > max_turns: default is tuned for fast frontier models. bump from 30 to 50. slow local models need more breathing room per agentic loop. >gateway_timeout: raise from 600 to 1200. local inference at 12-17 tok/s will timeout silently and look like crashes. > context accumulation: auto-reset is off by default. your session grows until you /reset. long convos choke the agent. reset between major tasks. if you're running anything under 20 tok/s locally, these three settings are the difference between "broken" and "flying." tune your config before you blame the tool.
