Poll of the Day

Yale College has announced a policy of Universal Pass / Fail. (See Yale Daily News)

The changes mean that the College will forgo letter grades and, instead, students will receive a “pass” or “fail” on their transcripts. According to the Committee on Teaching and Learning report circulated among faculty members before the second vote students who complete “outstanding” work may receive narrative commendations from faculty. These commendations will not appear on students’ transcripts, the report states.

What is your reaction to the Universal Pass / Fail policy?

Security and Privacy Implications of Zoom Some of you took my CS 257 course on Informatation Security. Apparently zoom is rife with security issues. This article is by Bruce Schneier who is a leading security guru, not some quack.

Widely used, including British cabinet meeting.
Bad Privacy Practices: selling data, sending data to Facebook, treating home pages as marketing websites.
Bad security practices: third party can turn on Mac user's camera overriding local security setting, can steal users' Windows credentials, display LinkedIn data, sloppy encryption: claim AES-256, but use AES-128, in ECB mode (electronic code book - not a good idea), use servers in China, have 700 developers in China, who could slip in backdoors a Chinese authorities request.
Bad user configurations: zoombombing, meeting id's are too short - hackers can randomly try them - there are tools for this!

I have office hours Wednesdays from 4-6 pm, via zoom, standard meeting id: 316-021-726

ULA office hours - also on zoom. See the [Contact Info and Schedule] as well as piazza. The zoom office hours meetings are posted on canvas, under zoom. If you have trouble connecting, post a note to piazza or email cs470help@cs.yale.edu.
