Hi 👋🏼, I am Niklas, a DevOps engineer from Cologne, Germany.

I recently set up nono sandboxes on my Mac to put my Claude Code sessions into a more restricted playground. Having Claude live unrestricted on my whole filesystem did not feel right, especially knowing that it could (potentially) request pretty much any website out there as well. No one wants to experience prompt injection or random deletions of your database or even your file system records.

(Or at least I will try to build it)

There is no hosting provider like AWS. Period. Their services are so advancement that European Hosters are faaaaar away from providing similar managed solutions. With the current advancements in politics, the need for such services increasing instead of decreasing.

Remember the problem you encountered month ago? That once in a life time error that took a day / week to sort out? Yeah it occured a second time. Did you take notes on how you fixed it in the first place? No? Have fun finding the solution again.

An exciting new development has recently emerged in the Deno universe. The new sandbox project, which is currently in the alpha phase, allows any JavaScript code to be executed in an ephemeral environment. This means that user- or AI-generated code can be executed without the risk of malicious code being brought to the host system.

It's a combination of technologies that makes my nerd heart beat faster: Deno and Firecracker VMs combined.

Over the last few days I have been building a tool that suggests possible titles, meta descriptions, a LinkedIn post and a newsletter issue based on my blog post files in Markdown. Personally, I want to focus on writing good blog posts that reflect my thoughts or work. As the content is more important to me than the 'marketing' around it, be it the LinkedIn post or the 'perfect' description of the article, I have considered using the tool to have this suggested by an AI model. My blog post is always used as the foundation, which is always attached to the prompt.
