Is there a breakdown of the expanded HTML/JS?

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/ You can see a screenshot of the demo here: http…

Caution: loud

Been years since I went through Beej's socket programming tutorial but I still recognize his code ;)

Does the high pitched sound make my Amazon Echo order something?

You'll know in a day or two.

So they're using p01's effect and they want to put ADs around it?

Interesting to see DEFLATE over GZIP here, as it is something I used to recommend maybe 7 or so years ago. I collected results for several years and began seeing more browsers dropping support for raw deflate (or switching to zlib deflate).

I accidentally let my hosting account expire years ago and lost the server code and db for it, but managed to pull the HTML from the way back machine. I've backed up the results here: https://davidmurdoch.com/compression-tests-results/. It's all pretty outdated now, but rather fun to look at.

Anyone know if this is using raw DEFLATE or ZLIB (HTTP 1.1 DEFLATE)?

Hi, this website is really loud and if you are using Headphones I would mute it or turn them down a bunch. It also will autoplay the sound.

Nice work. I guess it'd just as quick if it sent up to ~4kB - that's the normal TCP initial window? https://tools.ietf.org/html/rfc3390
