Спазм мозга: My Telegram Channel for Tech Brain-Cramps

A short note on my Telegram channel — a steady drip of MCP servers, AI agent news, security tools, self-hosting bookmarks, and the occasional book review.

A quick meta-post: I’ve been running a Telegram channel called Спазм мозга (“Brain Cramp”, @mind_cramp) since 2019. It’s where I dump the things that catch my attention before they vanish — tool releases, papers, eclectic bookmarks, and short Russian-language announcements of whatever I’ve been hacking on.

If you’ve followed any of my recent project posts (unix-pass-mcp, telegram-search, whitelist-probe, security-audit), the channel is the rough-draft companion. Rule of thumb: short notes appear on Telegram first, the long-form writeup lands here days later.

What’s actually in there

A rolling mix:

  • My own tool releases — short Russian-language announcements for projects I open-source. The polished version usually shows up here on the blog with the architecture and security posture spelled out.
  • AI / agents news — Claude Code, Cursor Automations, LangChain Deep Agents, the latest local-model drops (Qwen, Gemini, Llama). Mostly focused on agentic infrastructure rather than chat-assistant hype.
  • Security tooling — Bug Bounty kits, OSINT, hardware hacks (RaspyJack et al.), occasional CVE writeups.
  • Self-hosting & open source — Rust CLI tools, infra utilities, bookmarks for living a little less inside big-tech defaults.
  • Off-topic detours — book reviews, weird internet finds, things that genuinely cramp my brain. The channel name is a literal description.

It’s Russian by default — most of my readers are Russian-speaking infra and security folks — but tools and links work for everyone. If you read English-only, the GitHub repos linked from each post are usually self-explanatory.

Who it’s for

  • People who want a pre-blog feed of what I’m currently building
  • Engineers who treat their Telegram saved-messages folder as a second brain and need raw material for it
  • Anyone who liked the security-audit / telegram-search / unix-pass-mcp posts and wants the next one before I get around to writing it up
