Fade in. An opened terminal window. iTerm2 is the flavour. Dracula, the theme. You split the panes in two. You are at it again: a stash of audio buffers and that dream of manipulating a lossless file. With node as your language of choice you embark on the night. You manipulate, you transform, you have your byte order sorted, on their own accord your fingers start to type gzip -f yourFavPhilCollinsSong.wav.
All of a sudden, a whisper:

But what if.

we stream.

file compression.

on the fly.

Fade to black.

In this talk we will walk through file compression algorithms in node as well compression standards. We will cover working with streams, audio buffers, and typed arrays to get us to compress and decompress files, and yourFavPhilCollinsSong.wav.

Very nice talk, the initial, theoretical part was much interesting and, imo, more useful than the live coding / examples.

I think showing the effect of compression with page load time in browsers might enrich the talk.

Definitely interesting, and well executed.
Not "perfect" only because I was expecting a bit more code, maybe references to the issue of caching compressed files server side...

Interesting to see how compression can hit performance!

Algorithm explanations took a lot of time, no real life examples why someone would actually compress on the fly, but an ok talk

Abstract and the talk are not really in sync :(

Presentation was good, speaker was good but I would suggest instead of explaining the algorithms in depth to concentrate on the real life examples and share more personal experiences (in sense of pros/cons) towards cases when to use/avoid compression.
