Some years ago I've used the Lottie (Bodymovin?) library. It worked great and had a nice integration: you compose your animation in Adobe After Effects, export it to an svg plus some json, and the lottie JS script would handle the animation for you. Anything else with (vector, web) animations I've tried is missing the tools or the DX for me to adopt. Curious to hear if there are more things like this.

I'm not sure about the tools and DX around animated PNGs. Is that a thing?

Is there any place where one could look up screenshots of this? I'd want to see what is capable with this technology

theqwxason Show HN: Handwritten Christmas Card for Hacker News

If you visit the site without the subdirectory [0], you can see a message upload interface. The handwriting is supplied by the user (may or may not be AI-generated); the drawing movements are generated with some (hopefully non-AI) algorithm.

theqwxason Show HN: Book and change flights with one email

I am not sure about the US market, but Skyscanner [1] works great in Europe, I wonder how this is different. Besides from being structured as an email, it offers quite similar functionality of finding optimal flights (in some sense of optimal). It may just be me, but I am definitely misunderstanding the inbox metaphor. Why is it an inbox? Why is there emphasis on _one email_? I don't book flights through email -- I go on an airline's website to book.

For now it seems to be always responding with "Hi there, I couldn't find any flights for your request. Please try again.", I could not test it out. Unless this is a demo version, and is working as expected.

theqwxason How to avoid losing items? Holding pens

In this article, the meaning of _pen_ as in an enclosure, a cage, a tray, a box, a container [0]. A holding pen in this case means a holding tray, a holding box, i.e., a container for holding things. A pen (cage, tray) for holding things.

theqwxason RLHF is just barely RL

I agree that it's a very difficult problem. I'd like to mention AlphaDev [0], an RL algorithm that builds other algorithms, there they combined the measure of correctness and a measure of algorithm speed (latency) to get the reward. But the algorithms they built were super small (e.g., sorting just three numbers), therefore they could measure correctness using all input combinations. It is still unclear how to scale this to larger problems.

theqwxason Show HN: Aldi Price Map

I find these types of maps fascinating. For people wondering what would this map look like if we were not limited to the USA and Aldi: https://www.numbeo.com/cost-of-living/gmaps.jsp?indexToShow=...

There are a few larger categories (groceries/rent/etc.) rather than individual items.

theqwxason A game about staring into the eyes of a stranger

Talking about physical devices, I see you mention tablets in public places. Would you make them eye-catching, so people come up to them, or hidden, to be spooked by someone's stare? There is an interesting project in Vilnius & Lublin that just shows a livestream on what's on the other side (it's still up today) https://www.theverge.com/2021/5/30/22460964
