DavidHaerer··on Qwen3.8-Max: A New Bar for Coding and Cowork
According to [1] there is - unfortunately - increasingly more state in LLM sessions.

DavidHaerer··on Cheap self-hosted Kubernetes on Hetzner cloud (2025)
Given 6 months have passed since this article has been published, would you also pick MicroOS? I'm currently setting up a single-node k8s cluster on Hetzner but I went with Talos. Curious about your takes, IaC and k8s is new terrain for me.
DavidHaerer··on Ask HN: What Are You Working On? (March 2026)
I've started a side business to support local artisans.

I want to help people making a living from what they've created with their hands. A major focus to do so is to connect with local artisans and learning from their perspective.

On the technical side, I'm developing a static site[0] with Astro / React / Shadcn. The main interface is a OSM leaflet map with a custom calendar timeline.

As a software developer, this is my main entry in the world of agentic engineering. I'm using OpenCode with models from OpenRouter. One of the surprising insights is that there are often free quotas for new coding models (e.g. MiniMax). It's a very interesting time for building.

DavidHaerer··on Ask HN: What sources like HN do you consume?
I notice a lot of the suggestions are news-oriented. However, the thing I like about HN are all the non-news gold nuggets about tech. I'd love to find such gold nuggets for other industries as well.
DavidHaerer··on Ask HN: What sources like HN do you consume?
Can you recommend some of your favorite RSS feeds for non-technical topics?
DavidHaerer··on Show HN: Nostr Web – decentralized website hosting on Nostr
Nostr is append only, if an event is published to someone else's relay, you can't delete it.
DavidHaerer··on Show HN: Nostr Web – decentralized website hosting on Nostr
Nostr has built-in support (NIP idk) for Bitcoin Lightning payments. Bitcoiners see Nostr doing to social media what Bitcoin did to fiat.
DavidHaerer··on AI Coding
I think George is right about vibe coding. It's great for rapid prototyping, but in my daily programming on a production codebase, PRs must be reviewable, so I have to understand what I'm changing even more so.
DavidHaerer··on Helix Editor 25.07
I love the example with git blame for the current line. Helix is my daily driver alongside lazygit, however I much appreciate a tighter integration of Git in Helix. A colleague showed me what he can do with magit in emacs, and that was some next-level stuff (e.g. cycling the buffer through the Git history of the file). Previously I was using Neovim, but I'm really happy with my switch to Helix. So much less config, keybindings I find more intuitive and multi-cursor editing. For agentic coding I'm looking into Aider and OpenCode. I expect a tool like that to join my terminal setup with Helix and lazygit.
DavidHaerer··on Ask HN: Do you give up on side projects once you have a family?
The way I prioritize my time (work / family / hobbies / ...) I don't do any serious side projects.

However, when I became a father I started valuing my time much higher (watching less YouTube and reducing other time sinks).

So it made me more productive but also heavily reduced the time available.

DavidHaerer··on ePub to Audiobook Converter
btw it cost 10$ for an epub that is about 300 pages in print
DavidHaerer··on ePub to Audiobook Converter
This is such a nice project utilizing the advances in TTS models. Just converted an ePub in German via OpenAI. This gives me way more flexibility in reading / listening to books.
DavidHaerer··on Lumina Probiotic: strain of bacteria that prevents cavities
I'm very curious if this works. I'd like to have this product, but so far it's hard to find independent assessments and (long term) side effects as well are unknown. Also I think it's unclear if a one time treatment is enough or if it has to be reapplied regularly (e.g. after a professional dental cleaning).
DavidHaerer··on Ask HN: Embeddings as "Semantic Hashes"
Thanks for the insight!

A use case could be that anyone can provide a piece of content with the accompanying embedding and this can be used for semantic search. I.e. the search engine does not have to compute the embedding of everything, just the query.

DavidHaerer··on RnR: CLI tool to batch rename files and directories
I found this tool a while ago when looking for a way to batch rename some files.

I've previously used Perl rename[1], but as it has no safeguards, I find rnr much more pleasant to use.
