For those you are wondering, this is a webserver that serves an HTML page in a single TCP packet. I guess ≤ 1500 bytes to avoid fragmentation - shows as 1.1KB in Chrome's network view. The HTML contains embedded JavaScript that runs a simple demo with animated ASCII and playing a LOUD changing audio tone.
You can visit the demonstration website here: http://packet.city/ http://packet.city/
You can see a screenshot of the demo here: http://www.p01.org/128b_raytraced_checkboard/ http://www.p01.org/128b_raytraced_checkboard/
- ed 9y agoCaution: loud
- federicoponzi 9y agoOpened this on my phone with headphones. I had an heartattack.
- limaoscarjuliet 9y agoCounts as experience :)

- mrdoob2 9y agoSo they're using p01's effect and they want to put ADs around it?
- microcolonel 9y agoHere's hoping it's a joke. ;- )
- ConfucianNardin 9y agoThe limit is 1460 - the IP and TCP headers occupy 40 bytes. Out of those another 63 are consumed by the HTTP headers. The full TCP payload is only 1226 bytes though, and the full HTTP payload 1163 bytes. The decoded HTML document is 1546 bytes.
- bogomipz 9y ago>"Out of those another 63 are consumed by the HTTP headers" I am curious how you ended up at 63 for that, can you elaborate?
- coldtea 9y agoViewed the http headers and counted? Which you can do with curl, Chrome/Safari/FF dev tools, and lots of other tools besides.
- bogomipz 9y agoSure I know how to view them. I guess the commenter meant the HTTP headers for just this site were 63 bytes. I thought they were speaking on average like they were for 40 bytes for TCP/IP headers.
- jstimpfle 9y agoIP header has flexible size, up to 60 bytes: https://networkengineering.stackexchange.com/questions/6855/maximum-ipv4-header-size https://networkengineering.stackexchange.com/questions/6855/...
- bogomipz 9y agoSure but on the actual internet how often are IP headers larger than 20 bytes because options are turned on? Not very often. The 20 bytes each for TCP and IPv4 is a pretty good assumption. From the paper "IP Options are not an option" which is good quick read: "We have studied the dependability of IP options-enabled network packets in the Internet. We found that overall, approximately half of Internet paths drop packets with options"[1] [1] https://www2.eecs.berkeley.edu/Pubs/TechRpts/2005/EECS-2005-24.pdf https://www2.eecs.berkeley.edu/Pubs/TechRpts/2005/EECS-2005-...
- Dangeranger 9y agoThis would be really great without the audio. Due to the sound of the audio my initial reaction is to be fascinated, followed immediately by discomfort.
- isostatic 9y agoOver the last 5 years I've learnt to set the default sound level on my computer to "mute"
- homero 9y agoWow how'd it autoplay audio on my mobile chrome
- gizmo385 9y agoThat audio demo is CRAZY loud. I had my headphones on my desk since I'm on the phone and thought it was playing music through my laptop speakers.
