I received an email from an editor at Fabrikzeitung, a monthly magazine published in Zurich, Switzerland by Rote Fabrik. They were planning an issue about QR Codes and asked whether I would write an article expanding upon my post, Why does that QR Code go to justinsomnia.org? Of course! As an aside: I believe this is the first article I’ve ever been commissioned to write—and got paid for.
Well, they sent me an actual physical copy of the issue, and it looks very cool.
Here’s my article.
For those who might be curious, you can read the full text here:
The last time Justinsomnia went under the knife was 2007, and the web has changed a lot since then. Allow me to impress this upon you with a single image. The graph below represents the percentage of mobile browser traffic to my blog over those last 5 years. Hello iPhone and Android users!
In the span of a single year, mobile traffic jumped from almost nothing to nearly a third of my total traffic (before settling down around 15% this year). Given that there’s now a significant global audience of people browsing the web with smaller screens, I decided it was time to get up to speed on responsive web design. (If you’re in the same boat, I highly recommend checking out Apple’s developer docs on Configuring the Viewport. It was eye-opening.)
So I’m checking my blog on the hotel wifi, like ya do, and I notice something a little off with the style. There’s a dark colored bar at the top of the page that shouldn’t be there. That’s funny. Maybe a recent Firefox update changed how they treat CSS?
From November 2006 until June 2007 (coinciding with my use of Ubuntu’s Edgy Eft v6.10), there was a bug in the old photo importer (or in Gimp, I’m not sure which) that failed to set the Exif orientation tag to 1 (aka top-left) after rotating a photo. This was solved in the following release of Ubuntu, though the fix was somewhat incomplete—as I wrote about in How to fix Eye of Gnome’s photo orientation in Ubuntu Feisty.
What this means is that the vertical photos I edited in Gimp during that time had an Exif orientation tag indicating that the top-left of the image was something other than the top-left as it appeared when I hit save. The funny thing is that Firefox (to this day) completely ignores this orientation tag. So I had no idea there was a bug lurking in the Exif metadata of the photos on my blog.
