marckrn··on I spent the day teaching seniors how to use an iPhone
I used to work as a UI/UX designer when we bought our, now late, grandmother an iPad Air 2 so she could "stay connected." This was around the iOS 8 era, and helping her through the setup process turned out to be an eye-opening experience for me – and for my then-profession:

"Yes, yes, darling, I see all these cryptic hieroglyphs [icons] – but I don’t know what they mean. Am I supposed to? Where can I look them up?"

That was a long day.

Why do you think these aren't legit?

I'm pretty sure it's caused by RLHF :wink:

That's just a dynamic bogus prompt used to trace and extract the system prompt.

You're very welcome – that really means a lot coming from you, Simon.

Oh, I'm sorry. Yes, I'm using x's free tier.

I'm using Anthropic's pay-as-you-go API, since it was easier to set up on the server than CC's CLI/web login method. Running the bot costs me ~$1.8 per month.

The bot is based on Mario Zechner's excellent work[1] - so all credit goes to him!

You can find the revamped prompt on github[1], or on twitter summarized by my bot[2].

marckrn··on Show HN: Nia – MCP server that gives more docs and repos to coding agents
That's exactly what I tried to solve with https://github.com/marckrenn/rtfmbro-mcp (among other shortcomings auf context7 et al)
marckrn··on ChatGPT Search
They presented the link in the ChatGPT interface. Maybe this was an A/B-test thing, idk.

OpenAI also provides a Chrome Extension (https://chromewebstore.google.com/detail/chatgpt-search/ejcf...) to trigger a search from the omnibar as the default search engine.

If you don't like that (like I do), you can also manually add it under Site Search using

marckrn··on Disney's robots use rockets to stick the landing
I had a tour of Imagineering nearly a decade ago, and it was truly magical, leaving a lasting impression on me. It felt akin to what I imagine Xerox PARC or Bell Labs were like in their heydays.

AMA.

marckrn··on Things are about to get worse for generative AI
I too would love to earn a living by pursuing my hobbies. Too bad, I'm not in the 0,001-0,1%

Let's advocate for robust protections and support systems for artists, ensuring they can secure a sustainable and comfortable livelihood from their creative work.

Once they hit the tipping point of broad cultural absorbtion (think Banksy) AND/OR raking in absurd amounts of cash, move their IP into the public domain more aggressively (think Disney, NYT, etc.). How exactly this would work should be debated.

They'd still own the IP and have all the rights to use it commercially, but other's would be able to use it as inspiration, remix and maybe even resell it if attributed (or cheaply licensed).

In other words: "IP-Tax" the unproportionally successful.

marckrn··on Things are about to get worse for generative AI
I agree, but by extension of provoking emotion it CAN change society, but it doesn't have to - wether on purpose or not.

The point I was trying to make was that occupying mindspace, providing inspiration, being culturally influencal etc. are idealistic, non-monitary rewards that should be part of the equation when discussing alleged IP-theft, remixing, attribution and so on.

I'm not saying their shouldn't be any rules. All I'm saying is that there should be a discussion of how we want to handle these things going forward. This train ain't stopping.

Maybe your avg DeviantArt painter needs more IP-protection and -rights than Damien Hurst? Maybe an unknown, independent blogger doing important original research should be attributed more prominently than an article by The Times? Idk.

marckrn··on Things are about to get worse for generative AI
I might be a bit idealistic, but I've always believed that the core purpose of art and publishing should be to influence culture and society, not just to make a heap of money. That's why I feel original work needs its protection, but it should enter the public domain much sooner to fuel creativity and inspiration. We should be thinking in terms of a few years for this transition, not decades.
