We will consider the implications of two models that websites can use to generate revenue from their users: advertising and cryptocurrency mining. Advertising has been a popular model for website operators to generate revenue even though visitors do not pay to access their content, but advertising has some significant problems with security and privacy. We’ll explore these problems, look at two new approaches, and think generally about how web companies should generate the revenue they need to pay their bills while respecting and protecting their users.

While there are many excellent articles on the wide variety of issues related to this topic, the first three readings listed should serve as a good foundation for our discussion. The additional optional readings raise some important issues that we hope to touch on in the discussion, so take a look at one or two that interest you.

Computer science table (CS Table) is a weekly meeting of Grinnell College community members (students, faculty, staff, etc.) interested in discussing topics related to computing and computer science. CS Table meets Tuesdays from 12:00–12:45pm in JRC 224A (inside the Marketplace). Contact the CS faculty for the weekly reading. Students on meal plans, faculty, and staff are expected to cover the cost of their meals. Visitors to the College and students not on meal plans can charge their meals to the department (sign in at the Marketplace front desk).

For Friday's CS Table, we will examine some Web security guidelines in some depth.

The Open Web Application Security Project (2010). OWASP Top 10 - 2010 rc1: The Ten Most Critical Web Application Security Risks. Online document available at http://www.owasp.org/index.php/File:OWASP_T10_-_2010_rc1.pdf.

The reading is a bit longer than most, but can be skimmed fairly quickly by those who just want an overview.

Grinnell College's CS Table is a weekly gathering of folks on campus (students, faculty, staff, alums, etc.) to talk about issues relating to computer science. CS Table meets each Friday at noon in JRC 224A, the Day Public Dining Room (PDR) in the Joe Rosenfeld '25 Center (JRC). All are welcome, although computer science students and faculty are particularly encouraged to attend.

The Spring 2010 theme of CS Table is Software Design.
