As a warning, there seems to be no mouse-navigation of these slides. You have to use a keyboard. (or touch, probably)

There does not seem to be any indication to the user of what they're supposed to do to get the next slide, or even that there is a next slide.

EDIT: Well, OK, now that I maximized there is. But there was no indication that I was missing content to the left or right either. I appreciate simplicity but you gotta give first time users something to get them going.

But this is not for users. These are slides used in a talk served by presentation-oriented software. The user of the software is the person writing and doing the talk, not us. The fact that it's HTML5 makes it very easy to share with people who have not seen the talk, but the primary purpose of the tool is to help the speaker, not late readers.

Actually there is but it's actually a bug it seems..

You can scroll side to side to navigate through the slides (swipe left or right with 2 fingers on Macbook touchpad). However, this seems to only allow a few slides to load -- the swiping doesn't trigger the 'next slide' javascript so only a few prerendered slides are usable.

There's an interesting bug if you arrow past the end of the slideshow. It moves a distance not on a slide width boundary, so if you arrow back from there you're in the middle of the last slide, and so on.

Thanks I thought it was just me going crazy. This is the same on a macbook running Linux with Firefox. Is there a work around?

Just click on the right or left edge of a slide to navigate forward or back.

Ah you are right. Incredibly narrow area for my browser/screensize

I was wondering what system created the slides as well. Anyone know?

It's a tool called Present written by Rob Pike and Andrew Gerrand from the Go team:

https://code.google.com/p/go/source/browse/present?repo=talk...

They gave a presentation about it a couple of weeks ago at the Sydney golang meetup. It has an interesting feature where it runs a built-in websocket server that can be used to embed code in the presentation, and have it compile and execute output directly back into the presentation itself. I believe it's similar to the tech running behind the play.golang.org site.

Any web UI that requires a user manual is a major fail.

I'm amazed that people don't understand what this is. You are not a user. There is only one user -- the speaker who is giving the talk. Somebody gives a talk and uses this tool to present the slides. It shows the same UI elements as Powerpoint or Keynote when displaying the talk -- none. The presenter knows when he needs to do in order to advance to the next slide, and only he has to know. You wish to add back and forward buttons to Powerpoint as well?

This is a fantastic tool. The input is a text file, so it can be versioned, greped, and seded. It avoids huge and clunky tools. It allows code presented to be edited, compile, and run within the presentation itself.

Not to be a smart-ass but:

http://talks.golang.org/static/slides.js

From that:

So, I'm going to go with, "we wrote this ourselves and reused some code from other places in a couple spots".

Btw, holy-hell 2413 lines, they have to be using a generator for this.

Most of those lines are just linebreaks, and it's a fairly long slidedeck, so it's not impossible.

But you're right, it's generated from a simple, markdown-like format: https://code.google.com/p/go/source/browse/present/parse.go?...
