Determining smartphone market share using wireless sniffing

from Louwrentius [alt+shift+b] in technology

over a year ago
I started a project to see if I could track smartphone users by sniffing for wifi-clients. Most smartphones support wifi and most people don't bother disabling wifi when they go outdoors1. If wifi is left on, it is possible to detect these smartphones and track their movement. To...

So let's say you're working on a household project and need around a dozen telephone cables---the ordinary kind that you would use between your telephone and the wall. It is, of course, more cost effective to buy bulk cable, or simply a long cable, and cut it to length and attach...

The human face is remarkably complex, with 43 different muscles contorting the skin in all kinds of ways. Some of that is utilitarian — your jaw muscles are good for chewing, after all. But a lot of it seems to be the result of evolution giving us fantastic non-verbal...

My company has a buffet every Friday, and the lines grow to epic proportions when the food arrives. I've suspected for years that the “classic” buffet line system is a deeply flawed and inefficient method, and every time I'm stuck in the line has made me more convinced.

I've written before about the importance of iterating quickly but I didn't necessarily talk about some concrete things you can do. When I've built up the tech team at Better, I've intentionally optimized for fast iteration speed above almost everything else.

When Google killed Google Reader, the bloggosphere took a severe hit and the content quality went down because there weren't enough readers to justify the effort it takes to maintain a high quality blog.

What's left is a decaying wasteland of blogs, most abandoned, a lot are now SEO spam, and 99% are not worth reading. BoredReading is a way to read the remaining great blogs that survived the ice age.

To add your favorite blog, please suggest it here! I get emails every day which helps me maintain a high quality selection of blogs!
