I'm a cofounder of Amika (https://www.amika.dev/) (OSS repo: https://github.com/gofixpoint/amika).

We let users spin up sandboxed coding agents in the cloud, and control them interactively or programmatically. Each sandbox comes loaded with your git repos, your pick of coding agents, agent skills, MCP servers, and CLI tools, plus a live preview environment so you and the AI can see changes in real time.

I like running `claude --dangerously-skip-permissions` in Amika because worst case, I just delete the sandbox. You can also spin them up via API/CLI to do things like catch Sentry issues and auto-fix them in the background.

Little demo: https://youtu.be/OZzdBNBXxSU?si=4BwPQmFNq94-5T6H

We're excited about "software factories": using code-gen automations to produce more of your code. We still review everything that lands, but the process of producing those changes is getting more hands-off.

I've been writing a 'book' (more of an extended blog post that I'd like to put out for free) attempting to explain quantum computing to a layman-ish audience. I sort of got inspired to do this after seeing so many QC PR posts on HN, and finding the educational material in this space to be either too academic, too narrow in scope, or totally facile. I think given the incredible hype (and potential promise) of this ind…

One thing I would like to see addressed is the misconception that QC can help turn NP problems into P. I see this floating from time to time.

https://muffinman-io.itch.io/spacedeck-x I'm still obsessed with making my game, which you can try it at the link above (it is desktop only). This is my first "real" game, and it has been incredibly fun and rewarding. I've been working on it in the evenings for about 4 or 5 months. It is a very ambitious mix of genres - shoot-em-up and deck-building. A lot of people said that those are genres that shouldn't be combin…

This is awesome. I only made it to stage 5 but love the mix of genres

I recently launched a churn analysis tool for Stripe:

https://dunningbear.com

It is very basic now: it tells me which of the customers have cancelled their subscription and why (Stripe lets people choose the reason before cancelling). I've yet to gain a customer despite launching on the Stripe Marketplace but it's been personally helpful for me so far.

I'm building Tela ( https://github.com/paulmooreparks/tela ), a self-hosted relay that tunnels TCP services through encrypted WireGuard connections. The key difference from Tailscale and similar tools is that it requires no TUN adapter, no root access, and no admin privileges on either end. It runs entirely in userspace. My initial motivation was wanting to RDP and SSH into my home workstation from a locked-down corp…

ah nice. i’ve actually been building something pretty similar on top of wireguard too

my use case is a bit different though. i started because i wanted to give friends access to specific things in my homelab, but very selectively. like “you can use jellyfin on this one machine, but you can’t ssh, and you can’t even see my other devices”

tailscale is honestly amazing for getting devices connected, i still use it a lot. but once i started trying to do these very specific “this machine can talk to that machine only on this port” kind of setups, it started feeling more complex than it should be, at least for personal use. ACL editor is more confusing when it comes to this. i know we have got option for tags and things, but those are very poorly documented and i haven't found a single tutorial that works nicely.

your userspace approach is really interesting btw, especially the no tun / no root part. makes sense to run it on rigit enterprise environments.

This project started from a belief that llms should be better at doing python to cython code translations than they are. So we started setting a large set of parallel implementations.

Then I realized that Claude code was much better at working on the data using tools (mcp) to check and iterate. The scope transformed into an platform for creating the SFT agentic trace dataset using sandboxed tools for compilation, testing, linting, address sanitizing and benchmarking.

We still need to bulk up the GRPO dataset with a large number of good unmatched python examples. But early results using SFT only on gpt-oss 20b are quite good.
