Show HN: DataFuel.dev – Turn websites into LLM-ready data
15 by sachou | 1 comments on Hacker News.
Just launched DataFuel.dev on Product Hunt last Sunday, and I landed in the top 3! I built this API after working on an AI chatbot builder. Scraping can be a pain, but we need clean markdown data for fine-tuning or doing RAG with new LLM models. DataFuel API helps you transform websites into LLM-ready data. I've already got my first paying users. Would love your feedback to improve my product and my marketing!

Show HN: I designed an espresso machine and coffee grinder from scratch

It was a lot of work as a solo project but I hope you guys think it’s cool. When I say “we” in the website it’s only in the most royal sense possible. I also did all the photo/videography. I started out designing a single machine for personal use, but like many things it sort of spiraled out of control from there. I felt like espresso machines were getting very large, plasticky, and app-integrated without actually improving the underlying technologies that make them work. The noisy vibratory pumps in particular are from 1977 and haven’t really changed since then. So I wanted to focus on making the most advanced internals I could and leaving everything else as minimalist as possible. The pump is, as far as I know, completely unique in terms of power density and price. Without spending several thousand dollars, it was difficult to find a machine with a gear pump, and adjustable pressure was also similarly expensive but this machine has those things and costs a normal amount to buy. You can also turn the pressure way down and make filter coffee. I also saw so many people (including myself) using a scale while making espresso, and even putting a cup below the group head to catch drips, entirely negating the drip tray, so I basically designed for that! The profile of the machine is much lighter on the eyes and doesn’t loom in the corner like my old espresso machine did. And for the grinder, basically everything on the market uses conical and flat burrs that have descended from spice grinders, and the same couple of standard sizes. Sometimes larger companies design their own burrs, but only within those existing shapes. There is sort of a rush to put larger and larger burrs into coffee grinders, which makes sense, but with cylindrical burrs, you can increase the cutting surface way more relative to the size of the grinder. When grinders get too big, maintaining alignment becomes mechanically cumbersome, but the cylindrical burr can be very well supported from the inside, and there is the added benefit of hiding the entire motor within the burr itself. The resulting grounds are just outright better than all the other grinders I have used, but obviously this is a matter of taste and my own personal bias. The biggest downside for the grinder is that it doesn’t work with starbucks style oily roasts, because the coffee expands so much while traveling down through the burrs and can sometimes clog up the teeth. It doesn’t hurt the grinder but it does require cleaning (which is tool-free!). Another downside for both machines is the fact that they run on DC power so it’s best if you have a spot in your kitchen to tuck away the power brick. I also made a kit that makes the gear pump a drop-in upgrade for other espresso machines, to reduce noise and add adjustable pressure. https://ift.tt/VyZ8cLM The roughest part of this process were the moments midway through development where they weren’t working at all. When the grinder is just jamming itself instantly or the fourth factory in a row tells you the part you’re making is impossible or the pump is alternating between spraying water out the side and into your face and not pumping at all. And the default thought is “Of course it’s not working, if this was going to work someone else would have already made it like this”. The route you’ve taken is fundamentally different enough that there are no existing solutions to draw on. You’re basically feeling around in the dark for months on end, burning money, and then one day, every little cumulative change suddenly adds up to a tasty espresso. And it’s not perfect yet, but you at least can see the road ahead. Anyways, this is way more than I expected to write, thank you for reading! Tell me if you have any questions

Over 47? Have you gone through midlife transformation?
5 by throwandoawando | 2 comments on Hacker News.
The age of 47 is said to be the bottom of the midlife crisis U curve. Have you gone through this? If so, was it a period of professional transformation for you? How did you transform? Or, after a period of turmoil, did you eventually stay in your previous role? How did it relate to your personal life?

Apple App Store Review
3 by SSNLF | 0 comments on Hacker News.
Been on the App Store 10+ years and without going into details I believe my app has been unfairly targeted for things other apps are allowed to do. Lodged an appeal and feel like I'm getting the run-around. Has been going on for over a month. Would prefer to, and have been trying to use the official channels. Even the official Apple dev forum is "Your post is being reviewed and will be published if approved." Would really like a conclusive decision from the review board in writing so I can work out the next steps. Can anyone here help? Thanks in advance.

Gemini Flash 2.0 Experimental: A bit more accurate, but slower

I just updated my data extraction leaderboard with Gemini Flash 2.0 Experimental. It is quite a bit slower with large input token sizes right now, but a bit more accurate than Gemini 1.5 Flash which is at the top right now. Google and AWS are pushing out really competitive models right now. https://ift.tt/wcPNI8o
