The Psychology of the AWS Outage

Unless you've been living on another planet, you're certainly aware that over the past couple of hours Amazon's AWS S3 service has experienced a serious outage, which has affected thousands of sites and services around the world. For reasons I will elaborate in this post, the coverage of this outage has been blown completely out of proportion.

The Perils of Naive Sorting

I wanted to compare the aggregate cited half-life of works in different scientific disciplines. This figure tracks the median age of the articles cited during the last year.

Secure Passports and IT Problems

In 2003 Greece, in response to new international requirements for secure travel documents, revised the application process and contents of its passports.

U.S. military sites offer a quarter million Microsoft Word documents

I was Google-searching for the Air Force Operational Test & Evaluation Center publication "Software Maintainability - Evaluation Guide". To make my search more efficient I restricted it to military (.mil) sites, using the Google keyword "site:.mil". I was not able to find the publication I was looking for, but was surprised to see a number of Microsoft Word documents in the search results.
