Researchers show they can beat address space layout randomization with Javascript in a browser (!)

Address space layout randomization is an important first line of defense against malicious software: by randomizing where in memory instructions are stored, ASLR makes it much harder to overwrite memory with new code that will be jumped to as a program executes, offering significant protection against buffer overflow attacks.

Researchers discover hundreds of thousands of unsuspected, Star Wars-themed twitterbots hiding in plain sight

Twitter is a great place for bots. Botherders like Shardcore produce amazing, politics, artistic bots that mine Twitter, inject useful information into Twitter, or just frolic on Twitter, making it a better place. Twitterbots produce entries in imaginary grimoires, conduct sociological research, produce virtual model railroads, alert the public when governments try to make bad news disappear, and much, much more.

A potential college course on detecting and combating bullshit in all its forms

University of Washington profs Carl T. Bergstrom (Biology) and Jevin West (Information School) have proposed a course called "Calling Bullshit in the Age of Big Data" that characterizes "the majority of administrative activity" as "sophisticated exercise(s) in the combinatorial reassembly of bullshit" and aims to train students to "navigate the bullshit-rich modern environment by identifying bullshit, seeing through it, and combatting it with effective analysis and argument."
