LESS (CSS)

Posted on 2011-09-27

Found this handy javascript library that I think can be extremely potent: LESS. It basically gives scripting capabilities to CSS. For instance you can define a variable @color, and use that instead of using fixed values everywhere in your CSS file. This would ease when it comes to changing color schemes, for instance. But I think what will be most handy is the way it allows nested rules:

[sourcecode language="css" light="true"]
#header {
h1 {
font-size: 26px;
font-weight: bold;
}
p {
font-size: 12px;
a {
text-decoration: none;
&:hover { border-width: 1px }
}
}
}
[/sourcecode]

which basically defines the css-rule for e.g. "#header p" and "#header p a:hover". This will make cleaner css-files, and will let you write less CSS making CSS more DRY. It comes with a lot more powerful stuff as well like inline javascript. Have a look for yourself and see how you can make use of it.

Fairly technical post, but I wanted to put it down in text as I found it and reacted to it.

Boston Globe does HTML5 & Responsive Design

Posted on 2011-09-27

Here's an awesome article on how The Boston Globe implemented their HTML5 web page botonglobe.com using responsive design. For those who do not know responsive design, it is basically a way to create and design a web page to respond or adapt to the resolution of the web browser viewing it. It does not only take into consideration of rescaling images or text elements, but rather restructures the layout to best fit the screen. In the article they describe the technical challenges they went through: implementing Media Queries for outdated browsers; fast Responsive Images; how to sandbox third party ads to not mess with the page, etc. I am also very happy to read that they do no User-Agent detection, but rather do feature detection which is often advocated for HTML5 development, and that I do. The benefits of that is nicely explained in the quote

It is clear that we did not plan under any circumstances for anybody to be opening it on a GameBoy, but, when somebody did recently, it worked great on a GameBoy.

It's really nice seeing big projects starting to come out using HTML5 and responsive design. It definitely shows how it is unnecessary to write native apps for several platforms to get a great user experience.

Device Design Day

Posted on 2011-09-26

Stumbled upon this through Small Surfaces. A bunch of videos from Device Design Day, in San Francisco. You can find all videos here, but especially liked the one below by Dan Saffer. I liked it mostly for its brevity, because he is not the best speaker. But it's only 9 minutes long, and captures the way I perceive the way we think at Mobile Life. He says basically that we are part of the world, and by designing we change the world and therefore us. (Very very simplified, that I could go into length with.)

Ubicomp 2011

Posted on 2011-09-24

Just returned from UbiComp in Beijing. I co-organized the workshop Research in the large together with Henriette Cramer, Frank Bentley, and David Ayman Shamma.

The workshop was a followup on the workshop with the same title from last year. The workshop spurred some really interesting discussions, and most strikingly to me was how this year we were talking more about difficulties and problems, from previous year. Could be that you do not remember negative stuff as well as positive but, that was my impression. Also interesting was that a large part of the discussion was that in order to understand studies conducted in the large, you must combine them with studies in the small - i.e. small scale qualitative studies to investigate and triangulate with your findings in the large. This discussion was largely, if at all, left out last year.

Beijing also seemed to have become much richer than when I was there in 2008. It was cleaner, people more well dressed, and it was impossible to get a cab on a friday night as everyone was taking them. It is definitely an up and coming economy as they say, and I'm looking forward to see what they do with their new found wealth and increasing living standards. I also hope that it quickly reaches the country side as well.

Now it is back to thesis cranking.
