This is amazing. I've been looking forward to such a thing for a while now.

It's much easier to work with LISP. It's functional, trees are easy to reason about. We're using an even more simplified language in this work. It's kind of like the MNIST for progsynth research. Scaling this to real and

Yeah, this is true! These are more like expressions rather than programs. We were mostly following the language used by previous work, https://arxiv.org/abs/1906.04604

Changing tokens in a program is not differentiable. For me, the key idea is that you can train a neural model to suggest edits to programs by randomly mutating nodes. And when you run this neural model, you get to make edits that are syntac

I wasn't talking just about the US, I think we need very high levels of vaccination everywhere to make it statistically not a threat. We need to control the spread of the virus to levels where it's not mutating at evolutionarily s

Of course, we can never stop all mutations. However, for mutations to be useful for the virus, they do need to happen at an evolutionary scale. Especially because we're lucky that SARS-CoV-2 mutates much slower than Influenza and HIV.

Adding to the thoughts before, letting the virus spread and mutate among the unvaccinated to create a new variant sounds like a reset on the progress we've made. With the Delta we got lucky, our vaccines still largely work. I'm no

I've engineered it to be very inexpensive to run. I work on high efficiency video codecs, so one benefit is that I get to sometimes test my codec's and get real user feedback. I personally don't find virtual stuff fun, the pa

Hey HN! I am a TA for a large undergraduate class at MIT. Teaching virtually definitely comes with its challenges, but the biggest challenge for me was holding office hours. We used to have a queue system, with hundreds of students trying t

The difference here is that this library is a one-line drop into your Python back-end to automatically generate the client. Of course, the route you mentioned is much more powerful and complete, but here I'm trying to offer a way to ve

We bought a bunch of ov5647 camera modules from AliExpress. A quick search on the site yields a couple of listings at about $3.26 per camera, here is one of the listings, https://bit.ly/2W0Xui6

We spent the first month of the project on the v2 modules. These are based on the Sony IMX219. Unlike the v1 cameras, the datasheets are publicly available and even then, after much hacking around we couldn't get all the lines to expos

Thank you! That's super cool :) The fastest strobe we used was a 500ns strobe, which is a 1/(2e6)th of a second exposure. The Pi cameras use the OmniVision OV5647, dynamic range of 67 dB @ 8x gain. I'm pretty curious as to wh

My bad, maybe I should take more writing classes. I guess what's different here is we're not using a $300 DSLR. We're using a $5 raspberry pi camera. If we did the "let's take a bunch of high speed synchronized pict

Yep, that's the exposure time. LOL, yeah, it looks pretty sketchy. It is a proper bullet trap though, in fact the very same one that Harold Edgerton used for his famous bullet through apple image :)

We reverse engineered the camera module's I2C protocol and figured out how to ask it to to energize all pixel lines at once instead of it going line by line. The heart of it is just sending a few bytes down the I2C bus, but reverse eng

We use a strobe light instead of a mechanical shutter with a flash duration of 500ns.

To take a picture of a bullet, we take an exposure of 1/2,000,000th of a second. This is super challenging with cheap $5 cameras like the Raspberry Pi camera because of rolling shutter, timing, syncing etc and is traditionally done wit

It's a very generic off-the-shelf CNN + LSTM, with a few bells and whistles.
