I was recently asked by a client whether or not the cookie law will apply to its overseas business. As a reference, he provided a link to the Computer Weekly article “How to comply with the EU cookie law.”
It’s a handy article, but as with most reference material on the web there is no date on the article to give an indication how recent it is. Rules have changed a bit since the law was passed and so the requirements aren’t quite so clear anymore.
Obviously I am not an EU citizen nor an expert in international law, but I think you’ll find feedback from appropriate counsel would be similar (though probably a bit more risk averse).
We first introduced a notice about cookies in May 2011, and at that time we chose to ask for explicit consent for cookies. We felt this was appropriate at the time, considering that many people didn’t know much about cookies and what they were used for. We also considered that asking for explicit consent would help raise awareness about cookies, both for users and website owners. Since then, many more people are aware of cookies — both because of what we’ve been doing, and other websites taking their own steps to comply. We now consider it’s appropriate for us to rely on a responsible implementation of implied consent, as indeed have many other websites.
Back in October I had the pleasure of speaking at Buffalo’s second WordCamp. Unlike the talk I gave at least year’s event, I opted to go for something a bit more technical, something we build into every site we develop at Algonquin Studios and that I have been promoting for years now.
So I crafted a presentation on how to use print styles on a web site. At Algonquin Studios we support many platforms, including our own homegrown content management system (CMS), QuantumCMS. I have also learned that many WordPress developers also work on other platforms, so I opted to discuss print styles independent of the CMS used to power the site.
I focused on the background of print styles and related them to responsive design, I covered best practices and techniques, demonstrated how you can use Google Analytics to track what pages are printed from a site, and touched on the future of print styles.
All of my slides are here along with a video from my talk. Below the embedded content are links to other articles and posts I have written about print styles for those who want to get a deeper dive into some of the aspects.
Adrian Roselli: Making Your Site Printable
The video gets cut off before the end, but the key information is still in the slides.
During the course of a client web site upgrade today, one of the site’s visitors informed us that the web site was displaying an error and was exposing passwords in the error message.
While a password was in the error message, that password was only valid for the session state database and does not expose any other databases to access, including those with client data.
For those who would like a little more technical detail, the targetFramework error is expected while the site and applications are in transition across the .NET framework boundaries as the site is updated. The presence of the session state password and machine keys was not intended but was a side effect of an issue that has already been addressed. Some of the values are not in use and were commented out, but still displayed in the XML exposed in the error message.
As a result of this exposure, we removed existing accounts and set up new accounts and passwords.
Recently Opera moved away from Presto as its rendering engine and hitched its future to Blink, the rendering engine born from WebKit that powers Chrome. Now instead of Opera worrying about the rendering engine, it is focusing on the user interface, the place where it can set itself apart from the other browsers.
Essentially Opera is removing the browser chrome (implying to the user that a web page is just an app) and adding gesture support. Given that Opera was the browser that introduced us to mouse gestures well over a decade ago, and given that a touch screen is an inherently gesture-based UI, this seems like a natural fit.
Bits for Developers
Sadly, my office wifi was down and I couldn’t play with the browser immediately (my crusty iPad 2 is wifi only). So instead I took some time to read through the developer notes.
Overall Opera recommends general responsive design current best practices, though it promotes a tablet-first approach. Opera offers some CSS you can use to specifically target iPads Mini, 2, 3 and 4 (Retina and non-Retina), though it leans on vendor prefixes with only a brief note to also use other prefixes and unprefixed rules.
It’s also clear that Coast supports the new srcset option for responsive images. It even offers a code example: <img src="image.jpg" srcset="retina.jpg 2x">
Note: As Bruce was kind enough to inform me (because I missed it in the dev notes), responsive images will be supported only in iOS7 and up.
Update as of September 20, 2013
According to Opera, iOS7 did not come with a WebKit update. That means Coast cannot support responsive images via the srcset attribute without a polyfill. Nor can Safari, of course.
TileSpeed Dial Web App Image
Instead of “Speed Dial” icons/images, Coast now looks for a “web app image.” If you don’t have one, Coast will first look for a Windows 8 tile image, then an Apple touch icon, then a shortcut image, then just a favicon. You can, however, create your own 228 × 288 pixel image and stuff it into your site with the following HTML:
<link rel="icon" href="$URL" sizes="228x228">
User Agent String
Don’t use this to do any browser sniffing. Browser sniffing bad. This is instead handy for recognizing it in your logs:
Mozilla/5.0 (iPad; CPU OS 6_1_3 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Coast/184.108.40.206956 Mobile/10B329 Safari/7534.48.3.
Getting going is pretty easy, just start typing into the only field on the screen. As you type you can see a Google preview on the left, which you can tap at any time to go to Google, or a list of icons on the right which correspond to sites you might mean. The icons start out just displaying the first letter of the site, and then identify the site’s tile or shortcut image.
Once you are on a page, you can go back by swiping from the left, forward by swiping from the right, or reload the page by pulling down from the top — but not too far or you get the iOS menu instead.
Opera Coast skips tabs and windows altogether and, frankly, feels a lot more like Internet Explorer for Metro than other current tablet browsers. It’s pretty easy to see the open “tabs,” flip through them, get more details, and discard them. It’s also incredibly easy to forget you have so many tabs open. I regularly found myself littered with tabs because of all the links opening new windows.
While in that tab view, you can also see how “safe” the page is and can get to options to share it, email it, print it, and so on.
Adding and removing a bookmark, tile, whatever, is pretty easy. It took a few swipe-fails, but I got the hang of it well enough to show the whole process in one uninterrupted Vine:
There were a few things that threw me off. Perhaps because I am a power user, perhaps because I only played with it for one evening.
The swipe for back/forth is handy, but conflicts with behavior I have already learned. In Chrome for Android, swiping left or right has the infuriating feature of bringing me to the next or previous tab in the stack order. For those rare sites that implement a slide that is swipe-friendly, imprecise swipes will move me back and forth in the history instead.
Web App Images
Using the browser in portrait view, the additional screens of tiles (speed dial icons if you are already familiar with Opera) aren’t immediately apparent. It wasn’t until I turned to landscape that I saw them. The tiny dots under the Coast icon weren’t enough for me to intuit that. They also aren’t nearly large enough to tap to jump to a specific screenful of tiles.
The 9-box grid at the center bottom as well as the three rectangles at the bottom right are the only real browser chrome in play as you surf. They are also maddeningly small to tap. And I have dainty, lady-like fingers, so I suspect it may cause consternation for others.
If I am on a site and I want to change the address of the current page (maybe I fat-fingered and got to a 404, or I know a super-secret URL), I could not find a way to bring up the address bar and change it. It also made it impossible to know the current page address at any time. As someone who regularly looks at the URL for familiar addresses, indications of scam sites, quick commitment to memory, and so on, this alone takes it out of the running as an everyday browser for me.
Email a Page
I did not care for the email feature one bit. Not only does it embed a screen shot of the page (with a Coast watermark), the screen shot won’t display on other devices. Outlook blocked the image because the attachment ended in .com (not .png or .jpg). Had it not come from me, I wonder if Outlook would have blocked it as spam. My Android email client couldn’t display it because there was no file extension to give it a clue.
Tweet a Page
Tweeting a page left me similarly dissatisfied. By default it includes a Twitpic screen shot of the current page with an Opera Coast watermark. When composing the tweet, I tapped the paperclip icon to see if it would do anything, but nothing happened. I opted not to tweet again.
Overall, I like the browser. I like what it’s trying to do for consumers. As a power user, however, It’s not a fit for me though I’d be interested in bringing it in front of some other members of my family.
I also didn’t get to try out unsafe sites, printing pages, responsive images (need iOS7), or poorly-built sites. My opinion might change as I continue to play with the browser.
There are a lot of Android tablets out there, not just the four screen size offerings from Apple. So how long before we can see Coast on my Nexus 7, if ever?
I’m adding notes throughout the day as they come up.
Surprising no one, the following reviews from more mainstream sources completely fail to include any screen shots or videos that weren’t pilfered from Opera. I only say that to remind you that by reading this post you have gotten the most in-depth review currently on the web and you should be excited and send me a thank you note and maybe read all my other posts and high-five me on the street.
These articles are, however, worth visiting just to see the comments and how others are reacting to it.
On Friday, May 17 I had the pleasure of speaking for the first time at Stir Trek, a one-day conference in Columbus, Ohio, that drew over 1,200 attendees (and I understand sold out in just a few minutes). Apparently the name is a reference to the MIX developer conference, for which they were unable to obtain license to use a variation on the name.
I also had the pleasure of presenting for the first time on best practices for making your web site printable, built from my own professional experience, my PrintShame site, and an article I wrote for .net Magazine, among other resources (also linked in the presentation).
With 40 great speakers across 8 different tracks, there was quite a lot to offer throughout the day. Considering the other presentations held at the same time as mine, I was thrilled to get any audience and more excited to see that those who attended saw value in the topic and asked great questions throughout.
Well after the talk I got even more questions and feedback on the session, which I truly appreciated. Since there is no official survey for attendees to give feedback on a speaker, I am hoping any attendees will feel comfortable tweeting about it or leaving a comment here. So far I have gotten one great bit of feedback on Twitter:
Lest anyone think I’m just terminally negative, @aardrian had a REALLY GOOD talk on accessibility. And printability.
(I worked in some accessibility tips during my presentation.)
All other feedback is welcome (including if I was loud enough when the lavalier microphone failed).
While in Columbus I also had the pleasure of having a nice dinner (I arrived too late to make the speaker dinner), visiting the North Market, and, as part of the conference, getting to see a double feature of Iron Man 3 and Star Trek: Into Darkness. All around a good time which I look forward to repeating next year.
When I say “global,” I don’t necessarily mean the whole world, but really any aggregate pile of numbers for browsers that aren’t culled from your own site or project.
With IE6 finally fading (which many developers will claim is a result of their IE6-blocking sites), the ire of developers has turned to Internet Explorer 7. Given that many web developers want to play with the new shiny (and not worry about supporting older browsers) or hate the extra work that sometimes comes with supporting older browsers, it’s no surprise that disdain for IE7 is high.
It is with that experience that I think casually tweeting global stats and calls-to-action can be irresponsible without context, as this one on Friday:
The Akamai chart shows that IE7 is about on par with IE10 and even fares slightly better than Safari 6. The more discerning viewer might notice that Safari use goes up on weekends just a bit while IE7 use drops off for the same period, suggesting IE7 traffic might be coming from office workers.
Ignore Stats That Aren’t Yours
A few people try to make the point that those numbers don’t apply to their sites, some even try to make the point that this isn’t about browser support at all:
@js_dev @paul_irish you’re not supporting browsers, you’re supporting customers. Job #1 is serving your customers.
As an example, I have a site I was working on last night that gets 7.3% of its traffic (over the last month) from IE7. That’s about one in 14 users. I know I have to support users on IE7 because I look at the stats for the site, not because I look to Akamai, StatCounter, or anywhere else.
Here’s the takeaway I want everyone to recognize: The only browser statistics that matter are those for the site you’re supporting.
I feel so strongly about that point that I am going to quote myself just one sentence later:
The only browser statistics that matter are those for the site you’re supporting.
This Applies to Other Stats
I’ve seen plenty of people discuss window sizes over the years and make generalizations about what sizes to support — even more common in the era of responsive web design. But global screen sizes are irrelevant. Instead, look at the numbers for the site you’re supporting. Even better, look at the viewport size:
There has been a resurgence in discussion of late on print styles, but nobody seems to have any stats for how often users print pages. In the absence of raw data, developers talk about how they use sites and how their circle of contacts use sites. Instead, track it for your own sites and know when pages are being printed:
There are many other cases where developers look to global stats in lieu of tracking their own, but I haven’t written tutorials for them. Now might be a great time to consider writing some of your own for the data points you want to capture.
While supporting your users, and by extension their browsers, is the best approach, it is possible to get so focused on browsers themselves that instead of cutting edge you end up doing the opposite (even if it takes time to become apparent). Take this example from the UK Department for Work & Pensions:
The service does not work properly with Macs or other Unix-based systems even though you may be able to input information.
You are likely to have problems if you use Internet Explorer 7, 8, 9 and 10, Windows Vista or a smartphone. […]
There is also a high risk that if you use browsers not listed below, including Chrome, Safari or Firefox, the service will not display all the questions you need to answer.
The supported list of browsers and operating systems are combinations of Microsoft Windows 98, Windows ME, Windows 2000, and Windows XP with the browsers Internet Explorer versions 5.0.1, 5.5 and 6.0, Netscape 7.2, Firefox 1.0.3, and Mozilla 1.7.7.
A few months ago I had the pleasure of writing a piece for .net Magazine about print styles (Make your website printable with CSS). It was posted to .net’s web site last month and received an overwhelming one comment. That comment, however, summed up something I hear all the time:
Would be interesting to see some statistics on how many people actually print websites.
For years I have argued that the best user statistics are those for the site you are building. In the absence of global numbers for how many users print web pages, in this post I’m going to show you how you can measure how many (and which) pages get printed from your site by using Google Analytics. I am also hoping those who know everything about Analytics can answer some of my questions.
I want to be able to call the Google Analytics tracking image (__utm.gif) only when the page is going to be printed, skipping unnecessary HTTP calls and the resulting image download (brief though it is). I rely on the CSS @media print declaration to call the image. I also don’t want to write that image call to the page with yet more client-side script when I can assemble it all right on the server.
I still haven’t figured out what the number 5 maps to, but it works. I also found that I need an asterisk as a separator, though I found no documentation explaining it. In the end, the only way a print event tracked as I wanted was when I constructed it as: 5(Print*/Accessibility). In this example, /Accessibility is the address of the page I am tracking.
The other tricky bit is pulling the cookie value and stuffing it into the string. Conveniently I can get to this within our content management system (QuantumCMS, which you should use) on the server side. Many others (if not most or all) have a similar ability. At the very least you have to include the __utma and __utmz values, passed as encoded parameters for utmcc. Without these, my tracking would not fire.
The Completed Query String
For ease of reading, I will break the string to a new line at each &. This represents what is generated when I visit the careers page on the Algonquin Studios site using Opera.
Now that you have the query string and the Google Analytics tracking image, you just need to call the image when the page is printed. All you need to do is embed a style block at the top of your page with the print media query, and call the image within it:
If you read my post on embedding QR codes, then this code will be familiar — I use header::before in that example. As such, I use header::after here so you can use them both keyed off the same element (header) without conflict.
If you look closely, you may have noticed that my event parameter looks like 5%28Print*/Engage/Careers%29 instead of 5(Print*/Accessibility). I URL encoded the parentheses on the entire string to make certain that they do not conflict with the parentheses in the CSS. If you don’t do that, the browser will get confused and fail to load the image.
Once you have the CSS in place, I recommend going into HTTP Fox or the Chrome Developer Tools to make sure the image is called when you fire a print preview (save paper!), and then to make sure it has the parameters you expect — particularly the utme value:
Checking Your Google Analytics Report
Assuming you’ve verified all is working well, you just need to run a report for events in Google Analytics. Bear in mind that Analytics isn’t up-to-the-minute, so you may need to give it some time to capture all the data.
Log into your Analytics account and make sure you set the report date to the time period where you rolled out these changes. Choose “Content” from the “Standard Reports” on the left side. From there, expand “Events” and then select “Top Events.” You should see “Print” as one of the items in the “Event Category” column (you may need to show more rows).
Click on the word “Print” in that grid and you will see all the pages that were tracked (ostensibly because you or a user printed the page).
From here you can run a secondary dimension to cross-reference this with more information. In my example, I tested different pages in different browsers so I could quickly verify the cross-browser support. You can run screen resolution, landing page, or any other dimension that you think might be handy to compare.
I am just adding this to my own site, so I don’t have any numbers to offer as part of this post. However, if you implement this please feel free to let me (and everyone) know how many users you have who print and for what site. I don’t expect the numbers to be high, but I do expect to see it happen here and there.
If you have any additions, corrections or suggestions, please let me know. I am still unclear how all the Google Analytics query string parameters come together and exactly what they all mean, so there may be some optimizations I can work into it.
A combination of people who are far smarter, far more well connected, and in timezones that allow them to write about this sooner, along with all the Twitter chatter, has already hashed out the major details. As such, I will link to them below. I would be a terrible blogger if I didn’t offer my opinion, however.
Any developer who is complaining that this means there is another browser/engine against which they will need to test has been doing it wrong.
Web developers should always test against different browsers, regardless of their engine. In particular, WebKit has so many nuanced implementations that not independently testing against each browser that uses WebKit belies either a lack of understanding of how WebKit is implemented or laziness.
If you aren’t sure what is different between each WebKit implementation (Chrome, Safari, Android browser, Opera, etc.), I encourage you to read my post “WebKit Will and Won’t Be the New IE,” where I provide a high-level overview of these variances.
At this point it doesn’t mean a whole lot.
Google will argue this is better for users. Apple will argue that Google took its ball and left. Opera won’t be arguing. None of that impacts users because we have mostly done a good job of promoting standards-based development. I again refer you to “WebKit Will and Won’t Be the New IE” for how poor testing can impact users, but that’s not a function of the engines.
That’s just speculation on my part.
For a specification to become a W3C recommendation, there must be two 100% complete and fully interoperable implementations, which basically means two browsers need to support it. When Opera announced the shuttering of Presto, that left Trident (Internet Explorer), Gecko (Mozilla), and WebKit (Safari and Chrome) as the remaining engines (of measurable size). Essentially, two out of the three of them had to agree to implement a feature.
With Blink, provided the W3C recognizes it as a stand-alone engine, there is now one more engine back in the mix, essentially returning the count to where it was in February before Presto’s wind-down (to be fair to Presto, it’s expected to exist in the wild until 2020, but with no new feature development).
I am hoping that this is a good thing for standards.
Blink won’t be using vendor prefixes (even though it will have inherited some), so I consider that a step in the right direction. While I think this matters to developers, I think it matters even more to standards.
From Peter-Paul Koch:
Chrome 28 will be the first stable release to use Blink; earlier versions will use WebKit. Opera and Yandex will start using Blink whenever they start using Chromium 28.
First some bits from The Twitters:
Let’s bring back the Netscape engine and call it Spacer! RT @codepo8: After blink Microsoft might bring out a new engine called marquee
For those of us who put together print styles for our sites, we’ve probably tossed around the idea of embedding QR codes so that users can quickly get back to a page they have printed. In the hardcopy version of my article for .net Magazine, “Make your website printable with CSS,” I show how you can embed QR codes in your page (it’s not included in the online version).
In my example I use the Google Charts API to generate the QR code on the fly. The problem in my example is that the QR code image gets called whether or not you print the page. Not only is this an additional HTTP request, it’s also an additional download that immediately gets hidden. This puts a bandwidth burden on users who aren’t printing, but it’s also the only way to support your users on Internet Explorer 8 and below (who may be the ones trapped at the office who want to bring the document home).
If you truly have no IE8 or below users, then the less bandwidth-hoggy approach is rather simple, if a bit inelegant.
Since each call to the Google Charts API to get the QR code must include the full address of the page, I cannot leave this to my linked CSS file (which is static, not run through any server-side processing), nor would I want to push every URL for every page of my site into that file. Initially I wanted to use a data- attribute to hold the URL and then, using the generated content feature of CSS, have it take that value and feed it into the content: CSS declaration to have it generate the image from there. Except that’s not how CSS works. You cannot use CSS to generate an image from a CSS variable.
The easiest solution is to a put a style block at the top of your page (something I hate doing) and feed the current page’s URL into the Google Chart API query string to dynamically draw the image. The rest of the styles that affect placement, spacing, etc. should all be in your print stylesheet already. The example:
That’s it. Now when (and only when) you call the print styles, the image will load. As proof, here is a screen shot using HTTPFox showing the page before the print styles were called and after, where you can clearly see the QR code is called only when the print styles are fired.
Note: This technique will not work in any version of Internet Explorer that doesn’t support CSS generated content, which includes IE 8 and below. Internet Explorer 9 and above happily include the QR code generated with this method.
This may be old news to some of you, but I haven’t found a place that collects this in one spot.
One of the most offensive experiences I have when surfing a site on my mobile devices is being forced to click through an advertisement for the site’s app in the iTunes store (even moreso when I am surfing on a non-iOS device). There is a fair number of sites I have tapped away from because of this (I also don’t expect to be served the page I came to see, but instead shunted to the mobile home page).
If yours is one of those sites, whether promoting your entire user experience or just a product, there is a less offensive way to present your pitch to users on iOS and Windows Phone.
Safari on iOS 6 and later devices can promote your app with a standardized banner. Essentially you stuff a custom meta tag into your page that references your App Store ID. If the user already has the app installed, then the ad becomes a launcher instead.
Microsoft offers a similar feature for users of Windows 8 in non-desktop mode who are also using Internet Explorer. I have not tried it, so I cannot explain how this works as the user changes modes nor how it works with the “charms” feature of Windows 8.
This code is relatively simple as well, though it requires two meta tags and supports up to five:
In addition to Google Play, BlackBerry App World, I looked for similar features for the Firefox OS and Ubuntu Mobile stores. I know there are other mobile platforms out there for which I did not look.
If you know of other app stores that offer similar features, please let me know so I can update this post.
One of our spin-off companies, SWRemote, has an app available for iPads. There is value in promoting the app to visitors of the site but not in blocking their access to the site content with a splash page or an extra click, especially if they are not on iPads. The SWRemote web site is powered by QuantumCMS (yes, I am promoting our web content management system), which makes it about 30 seconds of effort to add the necessary meta tag to the site.
If you are already a client of ours on QuantumCMS, all you have to do is choose Site Configuration from the Settings menu and pop into the Marketing tab. This is the screen that allows you to add custom meta tags. Press the Advanced button and you are off to the races. In the Name field, for this example, I just entered “apple-itunes-app” and in the Content field I provided the custom ID for the app appended to “app-id=.” As soon as I hit Save the web site was showing the app bar to visitors:
Oddly, even though the app runs on the iPad Mini, which is running iOS6, the app bar never appeared on the site when viewed on the iPad Mini. On an iPhone 5, the app bar started to appear and then disappeared — probably as the device recognized that there is no iPhone version of the app.
If/when there is an app available for Windows Phone, the process to add this feature will be the same, allowing the site to promote both apps dependent on the audience. QuantumCMS helps make the process easier, with no need to code any changes to your site templates.
