Some of the videos are broken for me (using Firefox). Otherwise looks pretty neat.
Compared to FRP it is perhaps a bit more declarative in the definition of scopes, but otherwise seems equivalent. I'm interested in more details on this. I'm also a bit confused by
> This model has not yet been formalised, and while the propagators themselves can be simply expressed as a function ... I have not yet found an appropriate way to express scopes and the relationship between the two.
This seems straightforward to me (e.g. a scope could be a set of types, where each distinct event has a distinct type) so I think I'm missing something here.
- aag 2y agoAll but two of the videos are broken for me on both Chrome and Firefox. I would love to see the rest! I encourage people to read the original Propagator Networks paper by Alexey Radul (advisor: Prof. Gerald Sussman of SICP) referenced in the Prior Work section. It's full of fascinating ideas. https://dspace.mit.edu/handle/1721.1/54635 https://dspace.mit.edu/handle/1721.1/54635
- orionreed 2y agoWould love to know which videos are broken and any other details so I can try and fix that!
- jedharris 2y agoNone of the MP4 videos play in Firefox. The MOV videos play fine. All the videos play in Safari. I have not tried Chrome.
- orionreed 2y agogood to know! seems that I'm using encodings for those which Firefox does not support https://stackoverflow.com/questions/73855321/why-wont-mp4-video-work-with-html5-video-tag-on-firefox https://stackoverflow.com/questions/73855321/why-wont-mp4-vi...
- mjcohen 2y agoThe same thing seems to apply for Zoom background videos.
- Kikawala 2y agoFirefox doesn't support H.265/HEVC. bridging.mov and examples.mp4 are working as they are H.264/AVC, the other videos are H.265/HEVC
- SrslyJosh 2y agoNone of the videos played for me in Safari 16. =(
- davexunit 2y agoYeah I can't see most of the videos, either. :( I absolutely love Alexey Radul's dissertation. So interesting to see this article show up on the HN front page after I just published my own experiment with propagators yesterday: https://dthompson.us/posts/functional-reactive-user-interfaces-with-propagators.html https://dthompson.us/posts/functional-reactive-user-interfac... I need to learn more about the design decisions behind scoped propagators and why they deviate from "regular" propagators.
- Yen 2y agoAs a workaround in firefox, I was able to right-click, "save video as", and open in VLC.
