I’m just going to leave this here. When moving to Amsterdam, I put together a quick scraping and spidering script to get a list of the most frequently used words in Dutch to practice learning Dutch and building my vocabulary. The thinking being that by using the most high frequent words, I would learn the language in a demand driven fashion – and learn what matters first! It’s got a few bells and whistles like Google translation links and context examples. I figure I’d share it, since it comes up once in a while. The Perl code as a Github gist. Here’s the top 100 words in Dutch. Run the script to get a larger sample. I want to develop[…]
Understanding consumer psychology and online behavior has become essential and mainstream knowledge for e-commerce development in 2012. While some of us might regret that the cat is out of the bag, it also means a lot of smart people are figuring out a lot of smart things. Below are what I found to be the most insightful and actionable articles in 2012. There’s two things mostly missing: Recommender systems are still exclusively the domain of data crunching and algorithms, while I’d like to see more on inspiration and getting people out of the filter bubble. The other thing I haven’t seen much of in 2012 is any interesting work on stickiness and loyalty. If you follow my twitter feed, you’ve seen[…]
Tripline let’s you create trips on maps. I just have to test how it works to embed their maps, so this blog has a little map tripline of the trip I did of Morocco, Spain and Portugal with @angelarhodes in April/May. Check it out – it’s a cool little thing to play with. Angela’s blogpost: Morocco – Assault on the Senses.
I’ve always felt that the idea of repeated significance testing error and false positive rates is a bit of a pedantic academic exercise. And I’m not the only one, some A/B frameworks let you automatically stop or conclude at the moment of significance, and there’s is blessed little discussion of false positive rates online. For anyone running A/B tests it’s also little incentive to control your false positives. Why make it harder for yourself to show successful changes, just to meet some standard no-one cares about anyways? It’s not that easy. Because it actually matters, and matters a lot if you care about your A/B experiments, and not the least about what you learn from them. Evan Miller has written a[…]
It’s almost 10 years old, but this is an excellent article from Greg Linden, Brent Smith and Jeremy York on how Amazon.com does product recommendations: Amazon.com Recommendations – Item-to-Item Collaborative Filtering
Interested in discussing psychology and software development? I’m at the OSCON in Portland, Oregon all week this and I would be really interested to chat with others interested in psychology. I’m mainly at the conference to help hiring for Booking.com so come and ask for me at the Booking.com stand in the Expo hall. And if you’re interested in any of the many positions we’re looking to fill also drop by, of course! Have a look at our available openings at the Booking.com jobs portal. We’re still trying to get hold of many, many experienced Perl developers, and we’re also willing to teach highly experienced developers in other languages Perl.
A funny discussion is going on at HBR Blogs: Management-type blogger Bill Taylor suggests our culture wrongly celebrates the super-stars, and claims great people are overrated, on the cost of well-functioning teams (via Igor Sutton). But, to illustrate his example he uses software engineers as an example. Cue outpouring of frustration – Bill’s getting hammered in the comment section. So what’s the problem? First, try to look past that Bill skipped 30 years of research and experience in software engineering and stamps into it like a PHB-cliche, seemingly assuming his opinion is as valid as any research on the subject. That alone probably ticked off the defensive reaction in any software developer accidentally stumbling into the Harvard Business Review blog[…]
I just want to share these very cool lists of cognitive biases. It’s so useful to just have an overview of these on hand – and obviously I’m not the only one thinking so, as there are several useful collections out there: 50 Scientifically proven ways to be persuasive A Visual Study Guide To Cognitive Biases – They’re beautiful. Stephen Anderson’s Mental Notes cards: Get Mental Notes: It’s printed and in a leather box! http://en.wikipedia.org/wiki/List_of_cognitive_biases – The plain overview The Psychologist View of UX Design.

Long time no posting, but this just had to go on here.
