Tom makes an endpoint for generating QR codes so you don’t have to rely on the Google Charts API.
He also provides a good definition of “serverless”:
Now, serverless is a very silly buzzword dreamed up by someone from the consultant class who love coming up with terrible names, so I promise I won’t use it any further. Your code obviously run on a server. It just means it runs on a server someone else manages.
Amazon call it a ‘Lambda Function’. Google call it a ‘Cloud Function’. Microsoft Azure call it simply a ‘Function’. But none of those are very descriptive, because, well, anyone who writes any kind of programming language generally writes functions pretty much all the time in much the same way as anyone who writes English writes paragraphs, and we don’t call our blogging software “Cloud Paragraphs”. (Someone will now, I’m guessing.)

You know what I like? Print stylesheets!
I mean, I’m not a huge fan of trying to get the damn things to work consistently—thanks, browsers—but I love the fact that they exist (athough I’ve come across a worrying number of web developers who weren’t aware of their existence). Print stylesheets are one more example of the assumption-puncturing nature of the web: don’t assume that everyone will be reading your content on a screen. News articles, blog posts, recipes, lyrics …there are many situations where a well-considered print stylesheet can make all the difference to the overall experience.
You know what I don’t like? QR codes!
It’s not because they’re ugly, or because they’ve been over-used by the advertising industry in completely inapropriate ways. No, I don’t like QR codes because they aren’t an open standard. Still, I must grudgingly admit that they’re a convenient way of providing a shortcut to a URL (albeit a completely opaque one—you never know if it’s actually going to take you to the URL it promises or to a Rick Astley video). And now that the parsing of QR codes is built into iOS without the need for any additional application, the barrier to usage is lower than ever.
So much as I might grit my teeth, QR codes and print stylesheets make for good bedfellows.
I picked up a handy tip from a Smashing Magazine article about print stylesheets a few years back. You can the combination of a
@media print and generated content to provide a QR code for the URL of the page being printed out. Google’s Chart API provides a really handy shortcut for generating QR codes:
For now, I’ve got the QR code generation happening on The Session for individual discussions, events, recordings, sessions, and tunes. For the tunes, there’s also a separate URL for each setting of a tune, specifically for printing out. I’ve added a QR code there too.
I’ve been thinking about another potential use for QR codes. I’m preparing a new talk for An Event Apart Seattle. The talk is going to be quite practical—for a change—and I’m going to be encouraging people to visit some URLs. It might be fun to include the biggest possible QR code on a slide.
I’d better generate the images before Google shuts down that API.

As if you needed another reason why QR codes are shit ..are you certain you’ve proofed it?

I had a lovely conversation at the Update after-party with Georgie about the infographic dress she was wearing. It’s quite lovely.

Wonderful musings from Matt on meeting the emerging machine intelligence halfway.

I flew with Lufthansa who are now offering mobile boarding passes. You can get a test boarding pass sent to your phone by SMS or email if you want to see how it works. In my case, I went to the boarding pass URL in a desktop browser, saved the page as a PDF and slapped that onto my iPod Touch using FileMagnet.
It worked a treat. When I was going through security and when I was boarding the plane, I showed my passport and my iPod. They took the iPod, put it under the same scanner they were using for paper boarding passes and scanned the QR code on the screen.
I like paper as much as the next dead-tree fetishist but this was one instance where I was happy to go digital.

Nice QR code patches (I don't mean something that patches code, I mean a patch that you sew).

The Google Chart API can produce QR codes. Neato!
