Weblog entry #79 for dkg
No problem, right? I've got a scanner and a web browser and i know how to use them both. Ha ha. Upon first connecting, i'm rejected, and i find the absurd System Requirements -- only Windows and Mac, and only certain versions of certain browsers. You also need Sun's Java plugin, apparently.
Deliberately naïve, i call their helpdesk and ask them if they could just give me a link to let me upload my scanned checks. They tell me that they want 200dpi images, and then give an absurd runaround that includes references to the Gramm-Leach-Bliley Act as the reason they need to limit the system to Windows or Mac, and that security is the reason they need to control the scanner directly (apparently your browser can control your local scanner on Windows? yikes). But they let slip that Mac users don't have the scanner controlled directly, and can just upload images (apparently the federal law doesn't cover them or something). Preposterous silliness.
The WorkaroundOf course, it turns out you can get it working on Debian GNU/Linux, mainly by telling them what they want to hear ("yes sir, i'm running Mac OS"), but you'll also have to run Sun's Java (non-free software) to do it, since their Java uploader fails with nasty errors when using icedtea6-plugin.
I set up a dedicated system user for this goofiness, since i'm going to be running apparently untrustworthy applets on top of non-free software. I run a separate instance of iceweasel as that user; all configuration described is for that user's homedir. If you do this yourself, You'll need to decide if you want the same level of isolation for yourself.
So i have the choice of installing sun-java6-plugin from non-free and having the plugin installed for all web browsers, or just doing a per-user install of java for my dedicated user (and avoiding the plugin for my normal user). I opted for the latter. As the dedicated user, I fetched the self-extracting variant from java.com, unpacked it, and added it to the iceweasel plugins:
chmod a+x ~/Download/jre-6u25-linux-i586.bin mkdir -p ~/lib ~/.mozilla/plugins cd ~/lib ~/Download/jre-6u25-linux-i586.bin ln -s ~/lib/jre*/lib/*/libnpjp2.so ~/.mozilla/plugins/Then i closed iceweasel and restarted it. In the relaunched iceweasel sesson, I told Iceweasel 4 to pretend that it was actually Firefox 3.6 on a Mac. I did this by going to about:config (checking the box that says i know what i'm doing), right-clicking, and choosing "new >> string". The new variable name is general.useragent.override and i found that setting it to the following (insane, false) value worked for me:
Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:18.104.22.168) Gecko/20060426 Firefox/3.5.18Note that this configuration might make hotmail think that you are a mobile device. :P If you try to use this browser profile for anything other than visiting USAA, you might want to remove this setting, or install xul-ext-useragentswitcher to be able to set it more easily than using about:config.
Once these changes were made, I was able to log into USAA, use the Deposit@Home service to upload my 200dpi grayscale scans. I guess they think i'm a Mac user now.
The FollowupAfter completing the upload, I wrote them this review (i doubt they'll post it):
The Deposit@Home service has great potential. Unfortunately, it currently appears to be overengineered and unnecessarily restrictive.
The service requires two scans (front and back) of the deposited check, at 200dpi, in grayscale or black-and-white, in jpeg format, reasonably-cropped. The simplest way to do this would be to show some examples of good scans and bad scans, and provide two file upload forms.
Instead, Deposit@Home requires the user to present a User-Agent header claiming to be from specific versions of Mac or Windows, running certain (older) versions of certain browsers, and requires the use of Sun's Java plugin.
Entirely unnecessary system requirements to do a simple task. Disappointing. :(
AcknowledgementsI found good background for this approach on the ubuntu forums.
The TakeawayI continue to be frustrated and annoyed by organizations that haven't yet embraced the benefits of the open web. Clearly, USAA has spent a lot of money engineering what they think is a certain experience for their users. However, they didn't design with standard web browsers in mind, so they appear to have boxed themselves into a corner where they think they have to test and approve of the entire software stack running on the end-user's machine.
This is not only foolish -- it's impossible. When you're designing a web-based application, just design it for the web. Keep it simple. If you want to offer some snazzy java-hooked-into-your-scanner insanity, i will only have a mild objection: it seems like a waste of time and engineering effort. My objection is much stronger if your snazzy/incompatible absurdity is the only way to use your service. A simple, web-based, browser-agnostic interface should be available to all your clients.
Even more aggravating is the claim that they don't think they should engineer for everyone. I was told during the runaround that they would only support Linux if 4% of their users were using Linux (which they don't think is the case at the moment -- if you are a USAA customer, and you use something other than Mac and Windows, please tell them so). I tried to tell them that I wasn't asking for Linux support; i was asking for everyone support. If you just use generic engineering in the first place, there's no extra expense for special-casing other users. But they couldn't understand.
And now, since i'll need to lie to them in my User Agent string every time i want to deposit a check online, those visits won't even show up in their logs to be counted. "Our web site deliberately disables itself for $foo users; we haven't written it for them; but that's OK, we don't have any $foo users anyway" is a nasty self-fulfilling prophecy. Why would you do that?
