Show HN: Bor – Open-source policy management for Linux desktops

Hi HN! I've been working on Bor, an open-source system for centralized Linux desktop management. Bor consists of a lightweight Go agent and a central server. Policies are streamed to clients over mTLS/gRPC in real time—no polling—and currently support Firefox, Chrome, KDE, dconf, polkit and package management, with more coming.

Show HN: Goulash – heckler/helper to local-LLM your shell as little as possible

I use the terminal a lot, but I don't remember every command, flag, and syntax available. ffmpeg, piping to awk, find, etc... I know I'm not cool enough, but it's crazy-making.

deepseek-ai/DeepSeek-V4-Flash-0731

deepseek-ai/DeepSeek-V4-Flash-0731 The latest release in DeepSeek's V4 family, "with substantially enhanced agentic capabilities". It's 304 billion parameters - 167GB on Hugging Face - but it appears to punch well above its weight. Artificial Analysis rank it ahead of MiniMax M3 - a 428B model. It's $0.14/million input and $0.27/million output pricing mea…
