I packaged up the "autoresearch" project into a new self-contained minimal repo if people would like to play over the weekend. It's basically nanochat LLM training core stripped down to a single-GPU, one file version of ~630 lines of code, then: - the human iterates on the prompt (.md) - the AI agent iterates on the training code (.py) The goal is to engineer your agents to make the fastest research progress indefinitely and without any of your own involvement. In the image, every dot is a complete LLM training run that lasts exactly 5 minutes. The agent works in an autonomous loop on a git feature branch and accumulates git commits to the training script as it finds better settings (of lower validation loss by the end) of the neural network architecture, the optimizer, all the hyperparameters, etc. You can imagine comparing the research progress of different prompts, different agents, etc. github.com/karpathy/autorese… Part code, part sci-fi, and a pinch of psychosis :)

Serious bugs often occur in third-party components integrated by other software. @ifsecure and I found this vulnerability in the Dolby Unified Decoder. It affects Android, iOS and Windows among other platforms, sometimes 0-click. project-zero.issues.chromium…

building a new reconnaissance platform? I have attempted to gather most of the open source tool-set into a mind-map. You might refer this XMind: xmind.net/m/Xy7XEW . Other file-types: github.com/himanshudas/RaaP #recon #asm #monitoring #bugbounty

Excited to share my latest research! h2c smuggling: request smuggling via HTTP/2 cleartext. Leveraging TCP tunnels provided by HTTP/1.1 upgrades, we can initiate h2c connections directly with compatible back-end services, bypassing proxy access controls. labs.bishopfox.com/tech-blog…

YOUR immunity is stronger than hydroxychloroquine (HCQ) Studies show HCQ is ineffective in treating/preventing COVID Meaning many patients who improved on it, improved by themselves. Our body is able to beat this virus in >90% of cases! THINK POSITIVE nyti.ms/2MXEXNB
