AIGA Interview

Published 19 years, 10 months past

For those of you who’ve always wanted to hear me talk very quickly over a phone connection: AIGA has put up a podcast of me talking with Liz Danzico about design, code, and An Event Apart.  At the end of last week, they published a similar interview clip of The Zeldman.  There are more interview clips to come from each of us in the next three weeks, so keep an eye on the AIGA site or their feed.

Originally these weren’t quite podcasts because they weren’t part of a feed, and thus had no enclosure to download through your aggregator.  AIGA has fixed that now, and you can grab the AIGA podcast feed via the Podcast directory page.  Or, if you want, go to the previously-linked individual resource pages and download the MP3 files directly.  Either one works for me.


Milk vs. Wood Screws

Published 19 years, 11 months past

Over at UIE‘s Brain Sparks, the brilliant and lovely Christine Perfetti talked recently about the 7-11 Milk test, and how web sites fail this test 70% of the time.

I’m glad to see that they intend to do more research on the topic, because I think there’s a lot more to the story than just buying milk, and I hope that’s factored into the future research.  Buying on web sites, to me, is not really a 7-11 milk purchase.  It’s more like trying to buy a wood screw for a specific purpose at Home Depot when I’m used to buying them at a corner market.

See, 7-11’s are all pretty much the same.  If you’ve been in one, you know where to find the milk.  Even if the one you’re in is laid out differently than you expect, the conventions are all pretty much the same.  Even if you’ve never been in one before, it won’t take long to get the lay of the land and find the milk.

But walk into a Home Depot and you’re immediately overwhelmed.  I want to find this one thing that’s so tiny compared to what’s in front of me!  There’s an immediate low-level feeling of futility.  Furthermore, any expectations I might have from my local market experience are useless, or even counterproductive.  And even better is when I ask for help and get sent to the wrong place, as has happened to me many a time in Home Depot.

Once I do find the wood screws, then I’m presented with a wide range of choices, and I have to determine which one is best.  Odds are that there won’t be anyone there able to help me make a decision, either; I’m on my own to try to figure out which is the best wood screw for my needs.  The feeling of futility returns.  If I’m not particularly invested in buying this wood screw, I might just give up at this point: faced with too many choices, most of which are going to be wrong, I might decide to make no choice at all.

Furthermore, it’s much easier to bail out of the buying process on a web site.  If I’ve gone to the time and effort of finding and visiting a Home Depot, I’ve invested something in achieving an outcome.  With a web site, I can just come back later.

You can probably draw analogies between the experience I just described and shopping on a web site: the overwhelming home page, the search to find something resembling I want, the misleading cues, the array of choices once I get there.  If web sites were as consistent as 7-11 stores, and online purchases were as simple as “I need milk”, then yes, a 70% failure rate would be abominable—almost unimaginable.  Neither is the case, though.

Mind you, this is not to suggest we should shrug our shoulders and accept this state of affairs.  I think that UIE has an opportunity here to identify the chokepoints (and I use that word on purpose) in the shopping process.  Done correctly, what they find could be applicable in physical space as well as on web sites.


A List Apart Returns

Published 20 years, 3 weeks past

A List Apart is back in business and sporting a radically new design.  Check it out!  Four columns on the main page?  Yes indeed!

I’m proud to say I had a hand in the redesign process, taking the visual goodness of Jason Santa Maria and turning it into living, breathing XHTML and CSS.  Keeping the pages from going completely crazy in broken browsers was an interesting challenge at times, but overall I think things came together rather nicely.  There may be a few glitches here and there, though we did our best to test widely and often, but if so we’ll handle them as they arise.

It was good fun working with the talented team members in this process, and I especially enjoyed being able to concentrate on what I know—building XHTML and CSS around existing designs—and leave the rest to other people who knew their stuff as well as I know mine.  Due to the strategic partnership between Complex Spiral Consulting and Happy Cog Studios, I look forward to assuming that role more often, and on ever more interesting projects.

Addendum: it seems the DNS change to point to ALA’s new Textdrive home hasn’t made it as far as I’d thought, so I’ll point you to the numeric IP address; that way, you can see it even if your local DNS hasn’t caught up yet.  Sorry for any confusion!

Addendum 2: it’s been long enough that the DNS change should have made it to all the far-flung corners of the net, so I’ve removed the numeric IP addresses.


On Blinksale

Published 20 years, 1 month past

Partially because it’s been touted as a great XHTML+CSS-based application, and partially because I could use better invoice management, I signed up for a free Blinksale account.  Having spent some time fiddling around with it, I’ll be the first to say that I’m pretty impressed by what’s under the hood.  The markup is just about as clean as a Web application gets, and it generally uses the right elements in the right places.  It might be a little div-heavy, but that’s not an easy thing to avoid.  The gang at Firewheel has done solid work there.

On the other hand, the visual design of Blinksale totally hurts my eyes.  Those are some amazing shades of green, boys.  I really wish they didn’t clash in quite that way.  Also, the entire application feels rather like a copy of Basecamp, from the way it’s organized to the ability to get activity feeds to the “Remember me for 2 weeks” login option.  Those are, of course, all nice options to have in this sort of application, but they still feel like copies.

The help system, on the other hand, turned out to be an enormously deep resource once I drilled in a bit.  Just about anything you could possibly want to know about Blinksale is in there somewhere, I’d wager.  Firewheel has definitely raised the bar there, and gets an enthusiastic round of applause for it.

Beyond that, Blinksale seems like it would be great for hourly consulting, or for invoicing items that are shipped to the customer.  For my purposes, though, it isn’t really an invoicing system.  Most of my work involves traveling to clients to conduct in-person training, so in addition to the consulting fee, there are expenses to bill and receipts to submit.  In some cases, there are clients who would likely refuse to accept a web-based invoice.

So I could use it as a way to track which invoices have gone out and which have been paid, but I could do that with an Excel spreadsheet or a Filemaker Pro database, or heck, I could even whip up my own little PHP/mySQL solution.  Adding in all the extra stuff, like e-mailed invoices and reminders and thank-yous, would be time-consuming, and it would be a truly major effort to add my own PayPal integration, as Blinksale has done.  It probably wouldn’t be anywhere near as polished (although it also wouldn’t have those retina-searing color combinations).  For basic invoice tracking, though, I’d be able to do everything Blinksale offers me, and not have limitations like only being able to store a total of three clients, or being limited to three invoices per month.

Now, remember, I’m talking about what it will do for me.  I’d like to stress that my situation is somewhat unique: not many freelance consultants earn a living in training.  For a freelance designer or even a small design shop, I can totally see Blinksale as being a great application to use.  I doubt I’ll see a need to upgrade to a paid account—but your mileage, as ever, may vary.


Don’t Read; Speak!

Published 20 years, 2 months past

With the debut of the WSP‘s ATF, a vigorous conversation has gotten underway.  Joe Clark weighed in with some suggestions, Andy Clarke got some rousing comment action, and more have spoken up.  This follows some recent and widely-cited thoughts from Matt May on WCAG 2.0 (with opposing view from Gez Lemon), and from Andy Clarke regarding accessibility and legislation (which inspired the publication of a different view from Andy Budd, not to mention another from Chris Kaminski).  I’ll join the chorus with some points of my own.  (Apparently, my recent post Liberal vs. Conservative was taken as a contribution to the discussion, which it wasn’t meant to be, although the points raised there are definitely worth considering in this context.)

This past May, I delivered a keynote at the 2nd International Cross-Disciplinary Workshop on Web Accessibility in Tokyo, and one of the major points I made was basically this: “Screen readers are broken as designed, and need to become speaking browsers”.

The problem is that screen readers are just that: they read what’s displayed on the screen for a sighted user.  In other words, they let Internet Explorer render the Web page, scrape the visual result, and read that.  I will acknowledge that in the tables-and-spacers era of design, this made a certain amount of sense.  That era is ending; in an important sense, it’s already over and we’re just cleaning up the mess it left.  Which is not to say that table markup is never and should not presently be used for layout purposes, nor is this to say that such markup should be used.  Okay?

What I’m saying is that screen readers need to become speaking browsers: they need to ignore how the page is visually displayed, and read the content.  Use semantic markup when it exists, and otherwise ignore the markup in favor of the actual words, whether it’s plain text or alt text.  Go from the beginning of the document to the end of the document, and ignore the CSS—at least that CSS which is meant for visual media, which these days is pretty much all of it.

You might wonder how a speaking browser should deal with a table-driven site, of which there are still quite a few, he said with some understatement.  One distinct possibility is to do what I just said: ignore the non-semantic markup and read the content.  I can accept that might fail in many cases, so I’ll present a fallback: DOCTYPE switching.  If a document has a DOCTYPE that would put a visual browser into standards mode, then be a speaking browser.  If not, then be a screen reader.

DOCTYPE switching has been, despite a few hiccups, incredibly successful in helping designers move toward standards, and allowing browsers to permit standards-based design without sacrificing every page that’s come before.  The same, or at least a very similar, mechanism could help audible-Web tools.

The WaSP has done great things in their efforts to show vendors why Web design tools should produce standards-oriented markup and CSS.  I sincerely hope they can produce similar results with audible-Web vendors.


Liberal vs. Conservative

Published 20 years, 3 months past

So it turns out that crackers can mess up your Web site with nothing more than a malformed HTTP packet.  You might think something as simple as HTTP would be basically risk-free, but no, I’m afraid not.  All it takes is interaction between programs that handle HTTP data slightly differently, and hey presto, you’ve got a security hole.

Ben Laurie weighed in on this:

“It is interesting that being liberal in what you accept is the base cause of this misbehaviour,” Laurie says. “Perhaps it is time the idea was revisited.”

That’s a reference to the late Jon Postel‘s dictum (from RFC 793) of “be conservative in what you do, be liberal in what you accept from others”.  This is done in the name of robustness: if you’re liberal in what you accept, you can recover from data corruption caused by unanticipated problems.

Laurie’s right.  The problem is that being liberal in what you accept inevitably leads to a systemic corruption.  Look at the display layer of the Web.  For years, browsers have been liberal in what markup they accept.  What did it get us?  Tag soup.  The minute browsers allowed authors to be lazy, authors were lazy.  The tools written to help authors encoded that laziness.  Browsers had to make sure they could deal with even more laziness, and the tools kept up.  Just to get CSS out of that death spiral, we (as a field) had to invent, implement, and explain DOCTYPE switching.

In XML, it’s defined that a user agent must throw an error on malformed markup and stop.  No error recovery attempts, just a big old “this is broken” message.  Gecko already does this, if you get it into full-on XML mode.  It won’t do it on HTML and XHTML served as text/html, though, because too many Web pages would just break.  If you serve up XHTML as application/xml+xhtml, and it’s malformed, you’ll be treated to an error message.  Period.

And would that be so bad, even for HTML?  After all, if IE did it, you can be sure that people would fix their markup.  If browsers had done it from the beginning, markup would not have been malformed in the first place.  (Weird and abnormal, perhaps, but not actually malformed.)  Håkon said five years ago that “be liberal in what you accept” is what broke the Web, markup- and style-wise.  It’s been a longer fight than that to start lifting it out of that morass, and the job isn’t done.

Authors of feed aggregators have similar dilemmas.  If someone subscribes to a feed, thus indicating their interest in it, and the feed is malformed, what do you do?  Do you undertake error recovery in an attempt to give the user what they want, or do you just throw up an error message?  If you go the error route, what happens when a competitor does the error recovery, and thus gets a reputation as being a better program, even though you know it’s actually worse?  That righteous knowledge won’t pay the heating bills, come winter.

“So what?” you may shrug.  “It’s not like RSS feeds can be used to breach security”.

Which is just what anyone would have said about HTTP, until very recently.

In the end, the real problem is that liberal acceptance of data will always be used.  Even if every single HTTP implementor in the world got together and made sure all their implementations did exactly the same strictly correct conservatively defined thing, there would still be people sending out malformed data.  They’d be crackers, script kiddies—the people who have incentive to not be conservative in what they send.  The only way to stop them from sending out that malformed data is to be conservative in what your program accepts.

Even then, it might be possible to exploit loopholes, but at least they’d be flaws in the protocol itself.  Finding and fixing those is important.  Attempting to cope with the twisted landscape of bizarrely interacting error-recovery routines is a fool’s errand at best.  Unfortunately, it’s an errand we’re all running.


Web Essentials 05

Published 20 years, 4 months past

Just as I prepare to leave for WWW2005 in Japan, John Allsopp has announced the details for Web Essentials05  in Sydney this September.  Everyone’s fave Molly kicks things off with a keynote, and there will be some great speakers: Tantek Çelik, Jeff Veen, Kelly Goto, Derek Featherstone, Douglas Bowman, Russ Weakley, Cameron Adams, John Allsopp himself, and more.

Oh, and me.  I’ll be there, too.  You can get all the details at the WE05 web site.  I heard great things about WE04, so I’m really looking forward to WE05.  Hopefully I’ll see you there!  It’ll be a fair dinkum, and very likely truly bonzer, no worries.

Did I use any of those colloquialisms correctly?


Deep Linking, Shallow Thinking

Published 20 years, 6 months past

So a few weeks ago you might have noticed a bit of brouhaha that surrounded the new Terms and Conditions for Orbitz.com, set to go into effect today.  For anyone who missed or forgot about it, a refresher:  in Section 6, you find this wonderful bit of total cluelessness:

We reserve the right to require you to remove links to the Site, in our sole discretion.

Linking to any page of the Site other than to the homepage is strictly prohibited in the absence of a separate linking agreement with Orbitz.

So under their Terms and Conditions, it would be forbidden for me to point to a press release that announces Orbitz suing some former employees; or to their mangled-markup list of press releases; or, for that matter, to a medium-resolution JPEG of the Orbitz logo (which is rather ominously referred to in the Terms and Conditions as a “Mark of Orbitz”, which sounds like something that might have been mentioned in the first draft of the Book of Revelation).

It should be noted, however, that Section 4 of the old Terms and Conditions contains this amazing little gem:

You agree not to create a link from any Web site, including any site controlled by you, to our site.

Because nothing could be worse than increasing traffic to your site.

So yes, this post is in complete violation of the both the old and new Terms and Conditions for Orbitz.com.  And if I had ever been, or ever planned to be, a customer of Orbitz—thus agreeing to said Terms and Conditions—that might actually bother me for a second or two.  But, as they say:

If you do not accept all of these terms, then please do not use these websites.

Boys, you got yourselves a deal.
