Yes if you have MIT or Harvard on your resume it will be memorable and stand out, but other than that... they are all basically looked at equally.
There are tiers to everything. If you think it's MIT or Harvard, and then everyone else is a tossup, I've got some very bad news for you.
You know what also doesn't meet those expectations? a degree from a diploma mill.
So what you're saying is that, since outside of academia no one cares about quality of education, employers don't mind (or maybe shouldn't mind, according to your opinion) degrees from diploma mills.
Also for what it's worth I took 8 weeks doing about 10 hours of work a week on Discrete math 1 and found it very interesting. My discrete math notes is a 1300 line org file that translates to a 29 page word doc. This doesn't include the many proofs and problems I practiced on a white board or on my iPad. I completed Operating systems in 5 weeks with about 15-20 hours of work a week. I used Georgia Techs Udacity course on operating systems to supplement my learning.
Which gives ~75h-100h, way more credible than the 15h the author mentions in the post..
My students have 3h/week of Lecture, 2h/week of labs which is about 75h of classes (15 weeks). If we add ~60h estimated time for two projects, it's 135h. It means to me that you had enough time to learn the concepts and may have internalized some/most of them..
