Hey buddy,

Man, quick rundown of some cool stuff from Hacker News today, Monday, June 2nd. Just saw a few things pop up that seemed interesting.

My AI skeptic friends are all nuts

Okay, first up, there was this post from Fly.io called "My AI skeptic friends are all nuts". It's basically pushing back against people who are super negative about AI, saying it's already way more capable and useful than they give it credit for, even if it's not fully AGI or perfect. The comments were pretty lively. Some folks were saying jobs changing is just how it goes, like when coders replaced Graphviz diagram makers or horse carriage drivers were replaced. Someone else brought up how AI, like ChatGPT, is getting surprisingly decent at helping with coding, even in languages like Rust, though another person countered that coding isn't usually the real bottleneck in projects anyway.

If you are useful, it doesn't mean you are valued

Then there was this one that hit home a bit, titled "If you are useful, it doesn't mean you are valued". It's about how sometimes being really good at a specific, necessary job means you get stuck doing it forever and don't get opportunities to grow or move up. People in the comments totally related, talking about having to self-advocate to get off projects they were too "useful" on. One comment mentioned that even if the company doesn't always value that usefulness in terms of promotions or pay, coworkers often remember the people who were genuinely helpful and friendly.

How to post when no one is reading

Saw a post about "How to post when no one is reading". It's about finding motivation to create stuff online even if you don't have an audience yet. Comments debated if writing is worth doing just for yourself or only if you expect people eventually. Someone pointed out that with all the bots and short attention spans now, getting noticed is way different than the 90s internet, maybe even harder.

Cloudflare builds OAuth with Claude and publishes all the prompts

Alright, back to AI – Cloudflare did this cool thing where they built an OAuth provider using Claude, and they actually published the prompts they used! It's on GitHub here. The original author was surprised how good the code was. Comments were a mix: some people were worried about hidden security issues when AI writes code. Someone else looked at the commits and noticed Claude initially included a "backup" encryption key that had to be manually removed – kinda scary! There was also debate about whether AI helping like this means they need fewer engineers overall.

Show HN: Kan.bn – An open-source alternative to Trello

Someone showed off a new open-source project called Kan.bn, which is meant to be an alternative to Trello. Always cool to see new open-source tools. Comments mentioned other existing open-source options too, like WeKan and AFFiNE.

Ask HN: How do I learn robotics in 2025?

There was an "Ask HN" thread where someone was asking how to get into robotics now. Lots of good advice in the comments. People said the best way is often to just start building something you're interested in, even if it's simple, and set realistic expectations because it's a complex field. Someone suggested looking into programs like FIRST robotics. Another point was that you don't always need super complex six-axis arms or machine learning; simple linear motors can solve a lot of problems.

Typing 118 WPM broke my brain in the right ways

This was a fun personal story: someone wrote about how getting really fast at typing (118 WPM!) felt like it rewired their brain. They felt like it helped them get into a flow state easier because there was less friction between thinking and getting code down. Comments agreed that high typing speed and tools like Vim help with flow, but some debated if it actually saves you *thinking* time or just the time it takes to type.

Japanese scientists develop artificial blood compatible with all blood types

And this last one is pretty wild if it pans out: Japanese scientists are reporting they developed artificial blood compatible with all blood types. Sounds amazing, right? But the comments were pretty cautious. Some people warned that this kind of thing is usually astronomically far from being ready for real-world use, and just because humans can tolerate it doesn't mean it actually helps like real blood does. Someone else noted that it might not even be the first time a Japanese team claimed this, referencing earlier reports from 2019.

Anyway, thought you'd find that stuff interesting. Talk soon!
