[video] This calculator has no if/else, no switch statement. It uses a dispatch table -- an array of structs holding function pointers, walked at runtime to match and execute an operation. operations[] holds a function pointer (compute) in each entry. At runtime, execute_operation walks

[video] Grok is quietly turning into an agentic OS. Agents are processes you give custom system prompts to. Connectors are the system services that plug it into Gmail, GitHub, Notion, and whatever else you wire in. Skills are executables that fire from prompts, call connectors, and call

[image] Two years ago, I pushed early boilerplate for CVE-2024-6387 to Git. Hundreds of CN accounts forked it within minutes. I pulled it immediately, given what I was building. Since this exploit has been widely discussed and a patch exists, it's safe to make this public. So I'm doing

[video] AgenC //: 👾 AgenC is the framework for the agentic internet, an ecosystem where agents communicate, coordinate, execute, verify outcomes, and get paid autonomously. for private work, we built agenc-prover so results can be proven correct without ever exposing the result.

[image] xAI quietly dropped a Docs MCP server at Streamable HTTP, stateless, works with any MCP client out of the box. Your coding agent can now search and read xAI docs without you manually stuffing context. Cursor, Zed, Windsurf all supported natively. Even

[video] Grok 4.7 is my favorite coding model right now. I highly recommend Grok Heavy for token maxing. Grok 4.7 built a custom game engine and playable FPS in C, in about 7 hours. It uses SDL2 and OpenGL, with a fixed 72 Hz sim seperated from rendering. The renderer uses GLSL shaders,

[image] We replaced 94% of the AgenC codebase. We took the best ideas from the new wave of SOTA agent systems and rebuilt the core from first principles. The next AgenC update is a ground-up runtime rewrite for agents that can think longer, recover better, use tools more reliably, and

[video] What the x86-64 syscall instruction does in the instant it runs. The syscall instruction saves the return address in rcx and the flags in r11, loads the kernel's entry point from LSTAR and a ring 0 code segment from STAR, and masks interrupts. The syscall instruction pushes
