    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 prog…

    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 …

    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 …

    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 …

    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 …

    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 pe…

    I run a completely free service https://firemeet.io Though I think gather's UX is actually very friendly to non-technical people!

    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 use…

    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…

    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://b…

    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 muc…

    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…

    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 bu…

    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 thro…
