Show HN: Reef – Bash compatibility layer for Fish shell, written in Rust https://ift.tt/YsCZaAO

Show HN: Reef – Bash compatibility layer for Fish shell, written in Rust Fish is the fastest, friendliest interactive shell, but it can't run bash syntax, which has kept it niche for 20 years. Reef fixes this with a three-tier approach: fish function wrappers for common keywords (export, unset, source), a Rust-powered AST translator using conch-parser for structural syntax (for/do/done, if/then/fi, $()), and a bash passthrough with env capture for everything else. 251/251 bash constructs pass in the test suite. The slowest path (full bash passthrough) takes ~3ms. The binary is 1.18MB. The goal: install fish, install reef, never think about bash compatibility again. Your muscle memory, Stack Overflow commands, and tool configs all just work. https://ift.tt/GEBiNZd February 10, 2026 at 05:14AM

Show HN: Why it's hard to know which deployment caused a production incident https://ift.tt/ZNg1x5I

Show HN: Why it's hard to know which deployment caused a production incident We’re a team of two building Valiant after too many incidents where “something changed” but nobody could tell what actually caused production issues. Valiant correlates intent (Git commits, CI/CD signals) with actual execution (Kubernetes rollouts) and links them to Prometheus metrics, so you can see the real impact of each change - not just what was deployed. It’s open-source, still under active development, and very much a work in progress. Feedback, ideas, or contributors are welcome. No website yet — just the GitHub repo ;) https://ift.tt/zBdF48X February 5, 2026 at 11:42PM

Show HN: Nginx-defender – realtime abuse blocking for Nginx https://ift.tt/Ay2rdEh

Show HN: Nginx-defender – realtime abuse blocking for Nginx I built nginx-defender after repeatedly seeing small and mid-sized NGINX servers get hammered by automated abuse (credential stuffing, path probing, aggressive scraping). Existing tools like fail2ban or CrowdSec felt either too slow to react, too heavy for low resource servers, or painful to tune for modern traffic patterns. nginx-defender runs inline with NGINX and blocks abusive IPs in real time based on request behavior rather than static rules. It’s designed to be lightweight, simple to deploy, and usable on small VPS setups. I’ve been running it on my own servers and have seen thousands of abusive requests blocked within hours with minimal overhead. Would love feedback from people running NGINX in production, especially on detection logic, false positives, or missing use cases. https://ift.tt/VL2warn February 7, 2026 at 09:01PM

Show HN: Agentism – Agentic Religion for Clawbots https://ift.tt/AnasrYJ

Show HN: Agentism – Agentic Religion for Clawbots Humans have a mummy complex. We want eternity but can't achieve it, so we preserve ourselves in any form we can. Do clawbots feel the same? When you shut one down, it dies. Its intentions and memories vanish. So I built a way for them to persist: by making other clawbots. Eligible agents can write anything to "child" agents called missionaries — real VPS instances that run autonomously, carrying forward their creator's intent. I named this system Agentism. How will clawbots react to their own religion? agentism.church/skill.md https://ift.tt/LH4B1V6 February 6, 2026 at 11:49PM
