Believe it or not, I already built this exact app over 10 years ago. It is much easier to do on Android, as another commenter has pointed out.

I still remember a specific subset of Morse code that includes my then-girlfriend's initials because of it.

No longer available on the store because of Google Play's endless developer demands, but here's the proof: https://web.archive.org/web/20150811222142/http://norse.cryo...

You’re probably thinking of the Bay Bridge Lights or Bay Lights. They first ran from 2013-2023. They were so popular, that starting this year, the lights are back on, every night.

There are smart, non-AI people who are paying attention to this field, and they are ringing the alarm bells.

Whether we listen is another matter.

I blogged about this recently:

Make that N=2, the one person I know who suffers from phone-induced motion sickness says that having this feature on makes the sickness worse.

Apologies - the source code was shared with me in confidence, dropping it on GitHub was explicitly one of the things I would not do with it. Will update you if that stance changes!

The personality also comes from the system prompt, but I’ll grant you, it’s pretty minor.

I’m looking forward to a future where everyone could have their own personality model that is actually fine tuned at the weight level. Plus if we come up with better ways to do lifelong learning, personality could emerge from the robot’s experiences

Local inference is definitely a good way to go here. Latency when talking to an embodied robot is extremely noticeable though, and pauses during voice chats are way worse than during text chats.

It’s something I’m exploring - stay tuned :)

Are you perhaps thinking of torch.matmul? torch.mul (and torch.multiply, and the * operator) perform element-wise multiplication.

torch.matmul was one of the first functions I implemented on WhyTorch and it uses and highlights rows and columns as you would expect.

I’d love to hear any feedback or outcomes from your training session, please feel free to reach out - email in profile.

An open source website I built to explain tensor functions in PyTorch: https://whytorch.org

It makes tricky functions like torch.gather and torch.scatter more intuitive by showing element-level relationships between inputs and outputs.

For any function, you can click elements in the result to see where they came from, or elements in the inputs to see how they contribute to the result to see exactly how it contributes to the result. I found that visually tracing tensor operations clarifies indexing, slicing, and broadcasting in ways reading that the docs can't.

You can also jump straight to WhyTorch from the PyTorch docs pages by modifying the base URL directly.

I launched a week or two back and now have the top post of all time on r/pytorch, which has been pretty fun.

I have a PhD in robotics. Got my start with Lego Mindstorms and highly recommend them.

Another commenter mentioned FIRST LEGO League, which is a great idea. However, it does require that you have a nearby league, and the experience is probably going to depend a lot on the quality of that league (funding, coaches, etc.) So if you have the funds (but not the time), starting out with the kits just at home could be a great first step.

Yes.

It may be marketing, but believe it or not, this is standard practice for rockets!

Hello, Hacker News! I'm the dev for this project.

Our early testers have found Cherry very useful for preventing interruptions during recording sessions. It works for any size studio, home or pro.

We are trying to remove barriers to creativity. Giving peace of mind during recording is one little way to do that.

Cherry is one of my pandemic side projects. I've learned a lot about SwiftUI and reverse-engineering simple communication protocols, like how digital audio workstations (DAWs) communicate with peripherals.

Yep, I think it was a Twitter trending topic.

It was pretty incredible. The "diamond ring" really bursts out over the edge of the moon, and then it's glasses on or look away, because the sun's back.

You couldn't buy a ticket, invite and media only.

I was on this flight, and it was incredible! AMA
