include() requests. This allows you to maintain your whole content and HTML on the server and have all the Ajax goodness rendering out a simple HTML string.
The code example for the validation is available on GitHub.
Another thing that is missing a lot in people’s approach to JS is a proper build process. That’s why a lot of people try to optimise for performance during development and leave hard to maintain, specialist code behind.
The conference experience
Speaking at pure online conferences is weird. For starters we had to change the order as Simon Willison is on his honeymoon world-tour and currently in Marrakesh, which meant his connection was flaky. The audio during his talk was not the best and he didn’t even bother with video.
It is a strange experience to sit there with a headset and talking to your desktop as you cannot see the audience. Talks get much better when you can interact with the audience, ask questions, see them falling asleep or seething with rage – that kind of thing. In an online conference this is missing and you cannot read the chat whilst you present as this is too distracting. Drew was suffering the most from this lack of interaction and I had my audio drop out once which meant I had to repeat some slides.
All in all I find these things work better when there is a discussion going on – like a moderator interviewing a speaker over Skype and people asking questions. The other option of course would be to record the talks beforehand and play them instead of hoping all works out fine live – it never does. Recording the talks and then having a pure Q&A session with the speaker on skype afterwards seems to me a better way to work with these issues.
The benefits of these conferences are quite cool. People do not have to travel, you can pay one ticket and let a whole office watch, speakers don’t need to wear trousers and the liver of the speakers doesn’t need to suffer as much as it does at normal conferences. I am not quite convinced about the “green” argument of these events as they do use up energy, too but hey, at least it helps people thinking “green”.
Online conferences are a good idea as an add-on but I don’t think they’ll replace conferences as the networking and “meeting in the flesh” aspect is lost and that makes them feel a bit clinical and cold. That said, Carsonified are doing a good job with these right now and are lovely people when you interact with them as a speaker.
