based in Montreal, Canada.
I have recently read some though-provoking articles that discussed data visualization by analogy to photography. I really like this analogy, both from a process perspective – photography and data visualization – and a people perspective – photographers and data visualizers. Anyone who takes a picture with a camera is a photographer in that moment, and anyone who makes a chart, diagram or map based on data is a data visualizer while they’re doing that. Both photographers and data visualizers produce images of information emanating from their subjects, to make a point, to record, to inform, to delight. Photographers choose the lighting of their subject and framing of their shots, then use cameras to capture their image. Data visualizers choose the data they use about their subject and the mapping of data attributes to visual attributes, then use algorithms to produce graphics. Both can post-process their images to exert even finer control over their products.
In an agile software development project, the role of the product owner comes with the responsibily of managing the product backlog. Most popular definitions of the backlog are quite broad, encouraging product owners to include in it every feature request, bugfix, idea related to the product etc. I have found it more helpful, however, to distinguish between backlog items on the one hand (i.e. changes that as a product owner I intend to be made to the product) and feedback items on the other (i.e. bug reports, feature requests, ideas etc.)
If you’ve ever been browsing the web and been annoyed by those One Weird Trick ads, or by ads for that product you looked at online last month and then bought offline, you’ve probably given a thought to blocking ads altogether. The response to this idea, from people who run websites for a living, ranges from “it’s unethical” to “it’s stealing!”. According to them, the reason you get to use a website without paying for it yourself is that in exchange you see ads and website owners gets paid by the advertisers. That’s a polite summary of the great Ad-Blocking Debate, which has been going on since the early days of the commercial web. I’m not going to take sides here; rather I’ll propose a compromise enabled by a recent development in online advertising technology. I’m going to describe a “weird trick,” if you will: how to use the same system as those ads that follow you around to block ads, all the while ensuring that the websites you frequent have nothing to complain about.
