A few years ago, when I learned how AJAX worked, I immediately figured-out that, once you have reached a web site, every action you perform while using the site can be tracked by the site owner. That you didn't need to submit a form to send information to the server. This is a behaviour that you can plainly see when you use GMail.

However, yesterday, I surprised by this behaviour. I was shopping around for an online service. I found a place that seemed to qualify and was ready to make a purchase. I proceeded to the checkout page and started filling the form. I was almost done when I noticed some of the small print at the bottom of the page. After reading this, I realized that I didn't really understand what I was buying so I just closed the page without submitting the form.

A couple hours later, I got an email:

I can see from our records that you attempted to place an order with *service provider* today, but for some reason you ran into difficulties and the order was not completed.

To apologise for any problems you may have experienced, here's a special link to receive 50% off the usual cost of our *service*!

When you understand how the web works and you think about this. This is not super surprising. The checkout form was using AJAX to send the data in the checkout form as I was typing instead of waiting for me to push the submit button. When their system noticed that I never completed the purchase, it kicked-in an automated response.

The problem is that this is completely unexpected. It creeps me out a little that they recorded what I typed as I typed it. I had a feeling that we had an understanding: As long as I don't press the proceed button, you don't know anything about me.

Even if I was a little creeped-out, I did reply to the email and asked them a question about this fine-print text that I didn't understand and they responded quickly and provided me with a good experience overall.

But the question remains, is this behaviour creepy or is it a good customer experience?

Yesterday, after an interesting debugging session, I was able to fix a long standing issue that was quite tricky to find. This problem had been plaguing the system ever since we inherited it from the customer. The problem shouldn't have been so difficult to find as it is really obvious when you understand what happened.

The reason why it eluded us for so long is that the root cause (database deadlock) was hidden behind layers of abstraction (ORM) that did not do a good enough job of abstracting the physical characteristics of the system.

Although the fix was simple, the root cause was tricky. To make matters worse, that pattern that caused the problem is used everywhere throughout the application. So this morning, I spent 30 minutes to write up an email explaining the pattern and the problems with it. The email also spoke of a way to fix the broken pattern. Sent it to everyone in the team.

To my surprise, the payout was immediate. Before the day was over, I had a patch to review. A problem with a customer notification email not going out. And lo and behold, the cause was a database deadlock. And the fix was to modify the pattern the way that was outlined in my email.

The lesson here is that knowledge is valuable, but it is much more valuable when it is shared.

This evening, after dinner, I went for a latte at Starbucks. I was enjoying the beverage listening to the standard coffee house music. Tracy Chapman if I remember although my odds are pretty good with that guess considering the location.

Then I did something I rarely do. I read the little thought on the cup.

Failure's hard, but success is far more dangerous. If you're successful at the wrong thing, the mix of praise and money and opportunity can lock you in forever.

-Po Bronson, Author

I kept the cup. Even took a picture to remember.

And then I started to ask myself if I was successful at the wrong thing?

Jeff Atwood had a really quotable sentence in his latest blog post: Coding Horror: Real Ultimate Programming Power

"Throwing a book of rules at a terrible programmer just creates a terrible programmer with a bruise on their head where the book bounced off."

This funny sentence expresses something that I have had a really hard time expressing for the past few years: Rules and processes don't make your terrible programmers better, it limits the damage that they can cause to your project.

Not all problems can be solved by adding process.

The only long term solution to dealing with terrible programmers is to give them the tools to become good programmers. Training, mentoring and support. And the training shouldn't be about process but about the craft of programming. Reading code, using a debugger, how to solve a problem with software.

This morning, while I was shopping at the store, I was looking for product reviews on my blackberry. Every search I made on Google issued a warning about the site being potentially harmful to my computer. Even sites that I know or run had this issue. This was obviously a mistake on the part of Google. They issued an explanation about this error on their blog.

Basically, it was a manipulation error in the lists they manage of known bad sites. I am sure Google has procedures to ensure this doesn't happen but things like that still happen in spite of best efforts.

We fell victim to something very similar this week. While we were testing an upgrade to the software of one of our customer's web sites, we misconfigured the staging server and sent outdated notifications to a few hundred of their customers. This must have surprised the recipients and surely triggered a few customer service calls that they were not counting on.

What make this story interesting is that we had planned for this and had prepared a procedure for staging that made sure to neuter the notification service. A manipulation error in the server configuration caused all this planning to go to waste. After we had fixed our mistake and notified the customer to expect a few strange calls, we looked at what happened. It was clear that the mistake did not sit with one particular individual but was a failure of our internal communication for this staging procedure.

At least we learned something and we can fix our procedure. But today's Google issue makes me feel a little better about it. Even the biggest web company in the world has its bad days.

We are currently redoing the design of the web site at work. Since we didn't want to use stock photography (we wanted to be more authentic), a photographer came to the office yesterday all day and snapped action shots of some of us.

The photographer would set the stage tell us to sit here and there and proceeded to take pictures. At one point, he turned to me and asked if I could go back to my desk and fetch some random papers and other office supplies to lay out on the table that we were using for the picture.

We put that on the table and he said to us with a wry smile: "Now, look passionate and happy and authentic". We all laughed and went on to perform exaggerated pointing gestures and striking phony poses worthy of an 80's Sears catalog.

And then, something interesting happened. François pointed at the random paper that I had brought from my desk and asked what project it was about. And that is all it took. We started a genuine, passionate discussion of this project. I went on to explain the customer's needs and discussed the various technologies that we were looking at. I went on to explain that the project was early in its conception and that it required a lot of investigation for some of the most innovative parts.

Then François and Sylvain started making suggestions and asking more questions and the discussion became quite animated. By that time, we had completely forgotten that the photograph was there. He had to intererupt our discussion to ask us to take a different pose.

I don't know if the pictures will come out good. But I don't think we could have faked a better passionate, happy and authentic than this.
