stereomood Agile Blog | Better Master Passwords: The geek edition I’ve always wanted to write a technical followup to an earlier post, Toward Better Master Passwords, but this time going into some of the math behind it. Today’s xkcd comic does that for me: Indeed, what took me nearly 2000 words to say in non-technical terms, Randall Monroe was able to sum up in a comic. This just shows the power of math, but that’s another issue. So for those of you who want to understand the comic and see how it relates to my earlier post, read on. But first read or re-read my earlier post on strong master passwords. If, like most sane people, you don’t want to dive into a technical discussion, then stop here and just read the original, non-technical, post that says the same thing as the comic. The only thing I’ll restate There is one concept (well, actually two concepts) from the Toward Better Master Passwords post that needs to be restated. This embodies two things that we need to take into account when looking at the strength of some components of security. Entropy

How Technology Could Help Fight Income Inequality Photo Economic View By TYLER COWEN Rising income inequality has set off fierce political and economic debates, but one important angle hasn’t been explored adequately. We need to ask whether market forces themselves might limit or reverse the trend. Technology has contributed to the rise in inequality, but there are also some significant ways in which technology could reduce it. For example, while computers have improved our lives in many ways, they haven’t yet done much to make health care and education cheaper. It is a bit harder to see how information technology can lower housing costs, but perhaps the sharing economy can make it easier to live in much smaller spaces and rent needed items, rather than store them in a house or apartment.
