- Show HN: I Turned DOOM into a Transformer
Doomformer compiles integer neural networks into ZDoom maps that run in ViZDoom. Voodoo dolls do the arithmetic, and sector light levels and plane heights hold the values. Python reads every value back and compares it with a NumPy integer reference at tolerance 0. It runs MNIST (97.16 % on all 10,000 digits, every pass exact), small transformers, a learning perceptron and a SUBLEQ machine. It is about 23,000 times slower than NumPy on a small MLP.

The repository includes three working exploit chains, a Docker-based lab (PHP-FPM, nginx, Apache mod_php) for reproduction, and pre-built Suricata, Sigma, ModSecurity, and Lua detection rules. The author recommends disabling session.upload_progress as an interim mitigation, noting the underlying memory corruption requires a full PHP patch to fix.

TypeScript MCP server for Argo CD that lets MCP clients (Cursor, VS Code, Claude Desktop) list, inspect, create, update, delete and sync applications, read logs and events, and run resource actions through natural language. It supports stdio and HTTP stream transports, with a stateless mode for multi-replica Kubernetes deployments. The security design is detailed: API tokens are read only from env vars or headers and never from tool arguments, the default token is bound to the default base URL, a per-host token registry covers extra instances, a read-only mode disables write tools, and the HTTP listener binds loopback by default and requires an inbound auth token if exposed.

Edi Life OS is a self-hosted dashboard (PHP 8.1+, MySQL, vanilla JavaScript) that combines focus timer, habits, goals, Kanban tasks, finances and notes in ten workspaces. It includes an optional Node.js MCP server that exposes 15 tools over stdio. The tools let Claude Desktop, Claude Code or Codex read the dashboard, create goals and tasks, log habits and record expenses. The MCP server calls only the app's bearer-token /api/v1 HTTP API and never touches the database or credentials. The README is candid about limits: the token has no scopes, there is no app-level rate limiting, and the secret-note flag is only a visibility setting, not encryption.

Nuvex is a Solana-native verifiable compute and oracle protocol, still pre-mainnet, whose own README documents unresolved security gaps instead of hiding them: its VRF proof verification relies on solana-ecvrf 0.0.1 (RFC 9381 ECVRF-Edwards25519-SHA512-TAI) which has no known audit, max_fee is stored but never actually charged, and VRF fulfillment is first-come among any node meeting the configured stake/heartbeat threshold β meaning an operator who funds several keys at a low minimum stake can selectively pick which randomness output gets used. The deploy-mainnet script is stubbed to exit before any transaction, and unresolved design questions (fee shares, challenge/reject state transitions) are tracked as explicitly blocked ADRs rather than quietly shipped.
