Launched today, this HN thread is the first public mention. Zero paying users yet, just finished building it over the past few weeks as a solo project.

If you want to try it: code `HNPRELAUNCH` on checkout, first month free, then 19€/mo (cancel anytime from your Stripe receipt). Limited to the first 20 redemptions, expires in a week.

Honest feedback on what breaks would mean a lot.

The 19€/mo is infra only. Claude Code inside the VM signs in via OAuth to the user's own Anthropic account. I'd love to explore bundling open models (Qwen, etc..) into the subscription down the line, but that needs product validation first, not going to ship something I'm not sure people actually want.

Shameless plug: https://clawk.work/

`ssh you/repo/branch@box.clawk.work` → jump directly into Claude Code (or Codex) with your repo cloned and credentials injected. Firecracker VMs, 19€/mo.

POC, please be kind.

New comment by celrenheit in "Ask HN: How do you decide a name for your product or side project?"

celrenheit — Tue, 01 May 2018 09:09:35 +0000

By setting aside the availability, it should be rememberable (for me it is either an animal or an object/person that represents the product/project). Lately, I chose the name Sandglass for a message queue (https://github.com/celrenheit/sandglass). The reason is that this project depends on an ID generator that I named sandflake (in reference to twitter's snowflake). So I chose the name sandglass because it is kind of like a glass with a lot of sandflakes flowing through it (like a message queue).

Another name I used was Lion for an http router but for no particular reasons :)

tl;dr: Stellar distributed exchange and Ligthning Network coming in 2018

New comment by celrenheit in "Ask HN: What did you work on in 2017?"

I worked mainly on open source side projects such as:

Sandglass https://github.com/celrenheit/sandglass a distributed, horizontally scalable, persistent, time ordered message queue. It was developed to support asynchronous tasks and message scheduling which makes it suitable for usage as a task queue.

Sandflake https://github.com/celrenheit/sandflake decentralized, sequential, lexicographically sortable unique id.
