Hey @Daniel-Pan, I’m a big fan of your work with Seafile. It’s by far the best open source alternative to Google Drive and Google Docs!

I love the idea of this as well.

Do you plan to make it available as open source software also? I think it goes a long way towards trust in the platform/software.

I just looked at Scaleway’s pricing for two popular open source models (gpt-oss-120b and qwen3.5-397b) and it’s meaningfully more expensive than alternatives (e.g., many you’d find on OpenRouter).

Isn’t that what Convex is doing?

Jooq with Kotlin for a back-end has been the best of both worlds for me.

Much cleaner, shorter code and type safety with Postgres (my schema tends to be highly normalized too). And these days I’ve got it well integrated with Zod for type safe JS/TS front-ends as well.

American here who values individual liberties greatly. I know things are politically tense at the moment, but I’m not sure I understand this popular contemporary sentiment.

I’ve always believed governments and companies should be regarded with fairly low trust, and the behavior of big tech companies and some recent government actions are great examples why.

But what disappoints me a bit about this moment is (the perhaps inevitable?) response to nationalism with more nationalism.

Just as I didn’t seek to punish the EU over authoritarianism in Hungary and Poland, I feel the current moment has many responding to the symptoms instead of the sources of the problems. This is not a defense of policies I believe concern you, it’s a question of priorities.

I think the author of the article got it right. Because in addition to privacy, I believe one should be able to navigate the internet freely without a mandate to do business with monopolistic dominant companies, which includes rights like ownership of your data.

42 here, played a ton of Warcraft II, but my favorite to return to now is definitely Warcraft III (or AoE II).

I suspect the timing of this and comments is not coincidental.

I pay for Docker licenses, even though not meeting the criteria for business size requiring it, as I wanted reliable image fetching for my self hosted container CI/CD pipelines failing docker hub image fetches.

But as of now, my oAuth logins to Docker expire within hours now, and I’ve been left with no choice but to scatter in search of diffuse container image alternative sources for my Dockerfiles to stop this madness.

My one way permanent migration from Docker Hub sourced images has finally left me with no reason to keep paying for Docker licenses due to whatever this misguided or blundered rate limit implementation is.

Great ideas for both :)

I wasn’t expecting the main topic of what I’ve been building to appear on the cover of hacker news today, so I was caught a bit unprepared, but they were definitely on the todo list next!

It just so happens that I’ve built one already: TUI4J (Terminal User Interface for Java).

https://github.com/WilliamAGH/tui4j

It combines a port of BubbleTea from Go, and Textual and other inspired rewrites of other functionality.

It’s a fork of someone’s earlier work that I sought to expand/stabilize.

I built a beautifully simple LLM chat interface with full dialog windows, animations, and full support for keyboard and mouse interactivity parity, showing what this Java library is capable of.

Example chat app: https://github.com/WilliamAGH/brief

Would love to see others build similar things with it!
