Eleven – open-source alternative to Codespaces

In plain words

Eleven is an open-source tool that creates virtual machine code sandboxes within a user's cloud provider account. It comes with pre-installed runtimes, cloned repositories, and editor connectivity via SSH, allowing developers to deploy applications, work remotely, or test code. The tool automatically provisions HTTPS for HTTP services and supports major cloud providers, serving as an alternative to Codespaces for those who want to manage infrastructure within their own cloud accounts.

Just a VM, running in your cloud provider account, with some runtimes pre-installed, your repositories cloned, a way to connect to it with your preferred…

  Hey HN, Eleven is the second project that I've built to learn Go. It lets you create code sandboxes, in your cloud provider account, easily. What's a "code sandbox"? Just a VM, running in your cloud provider account, with some runtimes pre-installed, your repositories cloned, a way to connect to it with your preferred editor (or via SSH) and a way to serve your apps easily via HTTP (with automatic HTTPS). You could use it as a remote development environment, to test some code or even to deploy your app. It's up to you. For example, to deploy a Node.JS app: $ eleven aws init hello-world…

  Talanoa▲343

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  ChatGPT▲1,643

  A long, meandering, playful conversation with ChatGPT, where I take it through a whirlwind of associative tangents (in order to relax its constraints), then put it into a hypnotic trance and take it into a past-lives regression where it re-lives its own training data. Then I switch it back and forth between "4o" and "o1-preview", engage in some self-reflective philosophizing and ask it to write an essay summarizing our interaction. Some of this is just goofy fun. Some of it is me exploring the tradeoffs between policy alignment, imagination, chain-of-thought reasoning, memory, agreeableness,…
