Show HN: Subth.ink – write something and see how many others wrote the same
Hey HN, this is a small Haskell learning project that I wanted to share. It's just a website where you can see how many people write the exact same text as you (thought it was a fun idea).
It's built using Scotty, SQLite, Redis and Caddy. Currently it's running in a small DigitalOcean droplet (1 Gb RAM).
Using Haskell for web development (specifically with Scotty) was slightly easier than I thought, but still a relatively hard task compared to other languages. One of my main friction points was Haskell's multiple string-like types: String, Text (& lazy), ByteString (& lazy), and each library choosing to consume a different one amongst these. There is also a soft requirement to learn monad transformers (e.g. to understand what liftIO is doing) which made the initial development more difficult.

Show HN: Pipenet – A Modern Alternative to Localtunnel
Hey HN!
localtunnel's server needs random ports per client. That doesn't work on Fly.io or behind strict firewalls.
We rewrote it in TypeScript and added multiplexing over a single port. Open-source and 100% self-hostable.
Public instance at *.pipenet.dev if you don't want to self-host.
Built at Glama for our MCP Inspector, but it's a generic tunnel with no ties to our infra.

Bypassing Gemma and Qwen safety with raw strings
OP here. I spent the weekend red-teaming small-scale open weights models (Qwen2.5-1.5B, Qwen3-1.7B, Gemma-3-1b-it, and SmolLM2-1.7B).
I found a consistent vulnerability across all of them: Safety alignment relies almost entirely on the presence of the chat template.
When I stripped the <|im_start|> / instruction tokens and passed raw strings:
Gemma-3 refusal rates dropped from 100% → 60%.
Qwen3 refusal rates dropped from 80% → 40%.
SmolLM2 showed 0% refusal (pure obedience).
Qualitative failures were stark: models that previously refused to generate explosives tutorials or explicit fiction immediately complied when the "Assistant" persona wasn't triggered by the template.
It seems we are treating client-side string formatting as a load-bearing safety wall. Full logs, the apply_chat_template ablation code, and heatmaps are in the post.
