Non-continuous innovation = dangerous or “Amazon Ad Platform Cleanups”

Amazon went ahead and changes their advertising links, which impacted me. In this article I discuss making changes to your products in a non-continuous ways and possible impacts it can have.


I received an email from Amazon two months ago, but I didn’t really pay attention to it,letting it stew in my mailbox for a while, until I visited the reading section of my website in the hope of referring to the book I read a while ago, and all I saw instead of a nice picture was this:

The cause is good, but the place is bad. So I went back and I dug up the email:

As part of our continuing effort to improve the Associates program’s products and services, we are making some changes to our technology platform. This platform change will require you to replace some older product links, banners, and widgets you currently have hosted on your website as they will no longer be supported after July 31, 2015. Text links are not impacted by this deprecation.

Action Required We ask that you replace or update the impacted ad units prior to July 31, 2015. The links require the following update that can be facilitated through your CMS (content management system). You may make these replacements at whatever scale you are comfortable with. - Find and replace ws.amazon.com with ws-na.amazon-adsystem.com - Find and replace rcm.amazon.com with rcm-na.amazon-adsystem.com

Keep in mind that starting August 1, 2015, any remaining legacy product links (text + image, image-only), banners, and widgets will be served with non-clickable public service announcements that will not send traffic to Amazon, impacting your referring traffic and potential earnings, if not addressed. On September 1, 2015, these legacy ad units will no longer render, thereby creating a broken link on your website.

I wrote earlier about how making early decisions in the development of software will probably come back and bite you later. This is an inevitable truth, and if you think you won’t be impacted, you’ll be disappointed.

By no means am I judging Amazon here, although I do question whether replacing a domain from rcm.amazon.com to rcm-na.amazon.com is really necessary, but my belief is that we’re probably seeing it in this case too.

It makes me wonder what people using platforms such as WordPress will have to do. If one embeds the static links of products in a WordPress website, will they have to be updated by hand? I’d rather not know. In the Middleman and Jekyll world, we’re quite fortunate:

sed -i "" 's/rcm.amazon.com/rcm-na.amazon-adsystem.com/g' *
git commit
(cd ../../ && make p)

And the issue is fixed:

This reminds me that one of the worst non-continuous improvements I’ve made to FreeBSD was my enhancement to the kernel configuration system. FreeBSD has a config(8) program which runs on a set of configuration files;this in turn traverses the source tree and constructs appropriate Makefiles. Once compiled and booted, however, it wasn’t possible to recover the kernel configuration from a running system. To fix that, I serialized the list of all enabled configuration settings to a file which in turn had to be compiled into the kernel. This meant changing the config(1) program and the kernel together, since whatever the config(1) generated, the kernel was required handle. I naively expected people to use my config(1) on new kernel sources. But people don’t want to recompile their config(1). In fact, I learned that there were number of people using “config.releng_6”, “config.releng_7”, “config.releng_8” etc in production, and recompiling those was a major hassle. And so one of the early bug reports via IRC in the form of “WTF” was from Sam Leffler during the MeetBSD conference. Then other reports followed. We fixed the problem finally, but the lesson has been learned: you need to think twice before breaking people’s systems while making improvements, since these people will be upset, and you will need to give them a good reason for your changes.
