A few thoughts on the holiday/winter ads by Apple and Samsung

I’ve been tweeting a bit today about Apple’s iPhone ad that is getting some attention this holiday season, along with a new one from Samsung. But I have some comments that are a bit more than 140 characters long, that I’d like to share here.

I first heard about the Samsung ad via Daring Fireball‘s link to it on YouTube. Check it out below.

I’ll admit to finding the hapless iPhone owner on the chairlift a bit funny. I’m a sucker for cheap laughs like a guy dropping his expensive phone (and later his skis too) from a chairlift. But almost immediately the “Geared up” Samsung owner is creepy. Stalker creepy. He’s supposed to come off like he’s got “the moves” or something (which is creepy enough anyway), but he doesn’t seem suave so much as dripping with white privilege. He can just make the woman next to him on the chairlift give him her phone number because… why not?

The next scene is what really bothers me: he takes a bunch of photos and video of her on the ski slope, without her permission or knowledge. Because… why not? And when he goes up to her at the bottom of the hill to show off his efforts, she’s not creeped out (or is she… maybe… just a little?) because… he’s a handsome white dude who’s all “Geared up” so of course it’s OK.

Of course it’s really not OK. In so many ways, it’s not OK. If this guy were a real person, I’d have plenty more to say about him, but he’s not. He’s an actor, playing a role, attempting to sell a product made by Samsung. So let’s talk about Samsung’s advertising efforts and how sexist they are. Fortunately for me Anjin Anhut already did (in more general terms, but this Samsung ad certainly fits the bill) in a great blog post on Saturday that I encourage you to read.

Let’s contrast the Samsung ad with Apple’s ad, entitled “Misunderstood”:

I have seen this ad at least 5 times now and every time I tear up. Do I feel that my emotions have been manipulated? Of course. This is a commercial. That a commercial would make me tear up… of course my emotions are being manipulated. But that doesn’t necessarily make it a bad thing.

Apple’s ad connects on an emotional level, because that’s where we are with this technology today. Both Apple’s and Samsung’s devices can do so many of the same things, and fill the same needs and desires in their users’ lives, that it’s really down to how we as the users of these products connect with them on an emotional level. That’s really what Samsung’s ad is trying to do, I think. It shows off more specific technologies than Apple’s ad does, but ultimately it’s connecting with its audience on an emotional level as well. But the audience, and the emotions, couldn’t be more different.

There is nothing sexist or creepy about Apple’s ad. It delivers an image we’re all used to seeing these days: the tech-loving teenager, apparently tuning out the people around them and the meaningful experiences they should be engaging in. But the teenager is misunderstood—he’s not tuning out. He’s capturing fleeting, magical moments in his family’s life and he’s creating… putting those moments together into an artifact the family members will be able to connect with long after the holidays end. It’s a commercial that can resonate with just about anyone. It surprises and delights, and it shows us how using an Apple product can help enrich the experiences that matter to us. (It is an ad, after all.)

The Samsung ad? Well, first of all, the ad is targeted at a very specific demographic. It’s an ad for dudes. Want to impress and seduce that hottie next to you on the chairlift? Samsung has just the tech to help you make that happen. Frankly I’m surprised they didn’t license Daft Punk’s “Get Lucky” just to underscore the message.

On one hand I find it kind of surprising that any company would think they could get away with running an ad like this today, but the fact is, it’s not surprising at all. This kind of advertising obviously works. It may alienate a huge potential audience but as Anjin Anhut’s blog post describes, it has identified a target audience and is more effective within that audience.

The problem with that strategy though is that the more you target an audience, the smaller it becomes. It may be a subset of the population that is far more likely to buy your product than the average, but you become increasingly confined to that narrow slice of the pie. Unless of course you run different and contradictory campaigns simultaneously (which happens all the time). But still, ultimately, you’re eventually going to reach a saturation point with that target market. Then what? You can retreat to a broader message, but how much damage have you done (not just to your business, but to the community) by that point? And was it really necessary in the first place?

Say what you will about Apple’s advertising, but I don’t think I’ve ever seen anything sexist, racist, or otherwise exclusionary—except of Windows users.

How to install Windows 8 on a MacBook Air

No longwinded backstory in this post. I’m just posting this here so I can remember it if I ever have to install again, since I seem to keep forgetting.

If you’re trying to install Windows 8 (or Windows 7) on a MacBook Air, and you boot to the Windows CD (from a SuperDrive, of course), you may find that when you try to select the BOOTCAMP partition, you get an error stating that Windows can’t be installed on this drive, because it’s in GPT format, and you need to have an NTFS partition.

Well, it doesn’t matter if you have that partition formatted as NTFS or not. The error is happening because of the way you booted up!

Quit the installer, and restart, holding down the Option key. Then when the disk selection comes up, don’t select the Windows installer, select EFI Boot instead. That’s it!

WordPress tip: A simple way to search all post types

I love WordPress, but its huge designer/developer community and extensible structure have made it possible to over-engineer a solution to just about every problem. And then under-document that solution.

Case in point: today I needed to add the ability to search across custom post types, along with pages. But by default search only searches posts. (That is, the “post” post type. Are you with me?)

This isn’t a new problem, even to me, although very few of the sites I build have (or need) internal search. It’s just not that useful on a site that doesn’t have hundreds of pages or posts, and most of the sites I build don’t.

In the few times in the past when I needed to be able to search across other post types, or other content like taxonomy data, I’ve relied on the Search Everything plugin. And judging by the fact that (as of today) it’s been downloaded 555,309 times, clearly I am not alone.

It’s a pretty good plugin, as plugins go. But it can be overkill, especially if all you need is the ability to search other post types.

And that’s where we run into the real, multifaceted problem with WordPress for developers: 1) there’s a plugin (no, make that dozens of plugins) for just about every obscure task, and 2) there are also several ways to go about building your own custom solution, especially if you’re building your own theme, but 3) the documentation is all over the place, and none of it is comprehensive.

Granted, by offering a targeted solution to a very specific problem in this blog post, I’m contributing to that documentation fragmentation, but whaddayagonnado.

There’s a fourth (and probably even more important) facet as well: plugins are developed independently by countless individuals (of varying degrees of skill), and it’s impossible for anyone to test them all for interoperability. The more plugins you install — especially if they’re excessively complex for the problem you’re intending to solve — the greater the chance you’ll introduce an incompatibility that will break your site. So it’s in your best interest to try to keep things as simple as possible. (And to err on the side of installing fewer plugins.)


If I understand correctly, every parameter in WP_Query can be passed in the query string, which means you can add corresponding input fields into searchform.php in your theme to modify the search functionality.

OK, now that was too simple (and abstract). Give me an example I can work with.

Here’s a one-line solution to get WordPress to search all of your post types (even custom post types), not just “post”-type posts. Add this into the form in searchform.php:

<input type="hidden" name="post_type" value="any" />

Guess what… you can also specify multiple specific types of posts using PHP’s method of using square brackets in your input name to pass in data as an array, like this:

<input type="hidden" name="post_type[]" value="foo" />
<input type="hidden" name="post_type[]" value="bar" />
<input type="hidden" name="post_type[]" value="baz" />

A caveat: I tried the above with page as one of the values and it didn’t work; it showed my custom post types, but not “page”-type posts. I suspect it’s because that’s one of the predefined type parameters that make the query behave slightly differently. So this solution isn’t perfect, but using any as the value will work: it gets “post”, “page” and your custom post types.

My goal was to have a simple search form that would just search all post types, so I made this a hidden field, but you could make it radio buttons, checkboxes or a select menu if you wanted to let the user pick, and this just scratches the surface of what you can do to customize your search form to leverage the capabilities of WP_Query.

What’s so Neue about Helvetica?

So, I was just reading Rani Molla’s post on GigaOM called What’s all the fuss about Apple and Helvetica Neue? and I felt compelled (as I so often do, about so many things) to comment on the issue here.

Contrary to how the GigaOM article seems to frame it, the controversy — the, if you will, fontroversy (I regret it already) — when Apple demoed iOS 7 at WWDC last month was not that they were switching to Helvetica Neue as the iOS 7 system font. It’s that they were switching to Helvetica Neue Ultra Light, a particularly delicate weight of the general Helvetica Neue font family. (I’ve read some things that suggest they’re reversing course on that decision based on developer feedback, but the GigaOM post doesn’t even touch that.)

The fact is, Helvetica Neue has been the iOS system font ever since the introduction of the iPhone 4. When the iPhone was first introduced, it used plain old Helvetica as the system font. But with the introduction of the Retina Display, Apple switched to the slightly more refined Helvetica Neue.

So the concern with iOS 7 is not Helvetica Neue itself — that’s been working out just fine. It’s this extra thin weight of the font, which becomes difficult to read at smaller sizes.

Personally I like Helvetica Neue Ultra Light. I think it continues the trend towards refinement Apple began with the switch to Helvetica Neue itself, and is demonstrated effectively in Cabel Sasser’s animated GIF featured in the GigaOM article. The version using Helvetica Neue Regular feels heavier and clunkier to me. That said, I do understand and appreciate the legibility concerns with Ultra Light at very small sizes.

I’m not sure how this will work itself out. I doubt Apple will switch to a different typeface, though they may increase the weight of the font in the final version of iOS 7. But part of the reason Apple went with Helvetica in the first place is that it’s neutral (at least in principle). It gets out of the way and isn’t distracting. It doesn’t convey any particular personality. It’s a “blank canvas” of a font, which makes it a perfect fit for iOS devices, where the device itself disappears and becomes the app you’re using. Developers don’t have to use the system font in their apps, but a lot of them do, and by keeping the system font as neutral as possible, Apple avoids predisposing apps to a certain personality or style.

This is exactly the opposite of the opinions expressed in the closing of the GigaOM article, and is I think the opposite of Apple’s intentions with the iOS experience. Using a custom font that “reinforces a more distinctive brand voice” would be the equivalent of sticking a big Apple logo on the front of the iPhone. Apple’s branding goes on the back (where it can be an effective marketing tool). It’s never a part of the user experience.

Maintaining session between SSL and non-SSL pages in CakePHP

It’s funny, in a way, that cms34 has been around for nearly five years now, and it’s only just become a real issue that we were not maintaining sessions between SSL and non-SSL pages. This is somewhat understandable: practically speaking, the only time it really matters to carry over the session between the two is when a user is logged in. (This might not be the case with all web applications, but for us, at least, there’s rarely enough happening in the session when a user is not logged in for it to matter.)

As it happens, not that many cms34 sites use SSL; not that many cms34 sites use the user login capability on the front end. And very few use both. But we’ve had a couple of new sites come online lately that do use both, and it’s become a bit of an issue.

The issue was exacerbated by the fact that I recently modified the Users controller to require SSL on the login page, if the site has an SSL certificate. Consequently there were issues with trying to access login-restricted, but non-SSL pages… redirect loops and other such fun.

What’s the problem?

The problem is simple: for obvious security reasons, sessions and cookies cannot be shared directly between two different domains. It’s possible (although less secure) to share them between both SSL and non-SSL on the same domain, and it’s also relatively easy to set them up to work between different subdomains. But if your SSL pages use a different domain name than the non-SSL pages, even if they’re on the same server, there’s no way to get them to automatically use the same session.

The solution (though still not ideal, as it can introduce the risk of session hijacking), as you’ll find in lots of places, is to pass the session ID as a query string variable. Then you can use that to restore the same session ID, even if it’s on another domain — as long as it’s on the same physical server.

Some improvements

There are two key improvements I made to the basic “pass the session ID in the query string” scenario.

First, when the session is created I am writing the user’s IP address (using $_SERVER['REMOTE_ADDR']) as a session variable. Then, when I am attempting to restore the session with the ID passed as a query string variable, I read the session file on the server first, and make sure the IP address in the file matches still matches the user’s current IP address. Only then do I restore the session.

Second, and this is an aesthetic issue almost as much as a security one, once the session has been re-established, and before any response has been sent, I strip the session ID out of the requested URL and redirect to that new URL. It’s all invisible to the user, and the session ID never actually appears in the browser’s address bar.

A look at the code

There’s a lot going on in the cms34 code, much of which is highly specific to this application. But in short the keys to making this work happen in two places:


I have a login() action in UsersController that handles all of the special functionality that needs to happen when a user logs in. The actual login itself happens “automagically” via AuthComponent, but Auth doesn’t know everything I need to have happen when a user logs in, so after Auth does its work, my login() action takes it from there.

Honestly not a lot needs to happen here to make this work. Just two things: you have to write the user’s IP address to the session as I noted above, and you have to pass the session ID in a query string variable on the redirect that happens when login is successful. My code looks a little something like this (note that I have an array in the session called Misc that I use for… miscellaneous stuff like this):

class UsersController extends AppController {

  var $name = 'Users'
  // Other controller variables go here, of course.

  function login() {

    // All of this should only run if AuthComponent has already logged the user in.
    // Your session variable names may vary.
    if ($this->Session->read('Auth.User')) {

      // Various session prep stuff happens here.

      // Write IP address to session (used to verify user when restoring session).

      // Some conditionals for special redirects come here but we'll skip that.

      // Redirect user to home page, with session ID in query string.
      // Make up a query string variable that makes sense for you.
      $this->redirect('/?cms34sid=' . session_id());


So far, so good. The rest of the excitement happens in…


Ah yes, the magical beforeFilter() method. There’s a whole lot of stuff going on in AppController::beforeFilter() in cms34, most of which is highly specific to our application. But this is where you will need to put your code to retrieve the session ID from the query string and restore the session… this function runs at the beginning of every page load on your site.

I’ve put this logic almost at the beginning of beforeFilter(), because we really do want that session restored as soon as possible.

Here’s a look…

class AppController extends Controller {

  function beforeFilter() {

    // Additional code specific to your app will likely come before and after this.

    // Only run if session ID query string variable is passed and different from the existing ID.
    // Be sure to replace cms34sid with your actual query string variable name.
    if (!empty($this->params['url']['cms34sid']) && $this->params['url']['cms34sid'] != session_id()) {

      // Verify session file exists.
      // I am using CakeSession; your session files may be elsewhere.
      $session_file = TMP.DS.'sessions'.DS.'sess_'.$this->params['url']['cms34sid'];

      if (file_exists($session_file)) {
        $session_contents = file_get_contents($session_file);

        // Find user's IP address in session file data (to verify identity).
        // The CakePHP session file stores a set of serialized arrays; we're reading raw serialized data.
        // If you used a different session variable name than remote_addr, change it AND the 11 to its string length.
        $session_match = 's:11:"remote_addr";s:'.strlen($_SERVER['REMOTE_ADDR']).':"'.$_SERVER['REMOTE_ADDR'] .'";';

        // User's IP address is in session file; so we can continue.
        if (strpos($session_contents,$session_match) !== false) {

          // Set session ID to restore session

          // Redirect to this same URL without session ID in query string
          $current_url = rtrim(preg_replace('/cms34sid=[^&]+[&]?/','',current_url()),'?&');

A few final thoughts

I didn’t really discuss cookies at all here, but suffice to say there’s a cookie containing the session ID that gets written. If you’re only using cookies for the session ID (which is probably a good idea), then you don’t really need to do anything else with them. But if you’re writing certain cookies when a user logs in (like I do), you’ll need to write additional logic to restore them in AppController::beforeFilter(). In my case, the relevant cookies are all duplicates of session data, but are intended for a few edge cases where I need to access that information through JavaScript or in .htaccess files that are protecting login-restricted downloadable files — in other words, places where I can’t use PHP to look at session data.

You may also notice near the end of the code in the AppController::beforeFilter() example above that I am calling a function called current_url(). This is not a built-in part of PHP or CakePHP; it’s a simple little function I have in my config/functions.php file. Here it is:

function current_url() {
  return (!empty($_SERVER['HTTPS']) ? 'https://' : 'http://') . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
