Love it. However, is there a way to add past courses to my "records"? When I try to add the past iteration of a course to my wall, it adds the next iteration.
Ah sorry about that - that's a bug. You should be able to add previous iterations of a course if you select the 'show past courses' checkbox. Will look into this and fix asap - UX for this does need some work too :)
Yeah, I selected the 'show past courses' checkbox and selected a course that was over a year ago. If you are looking for specific data points for the bug, it was the Coursera "Machine Learning" class.
Amazon has been profitable for many years now. YCharts showing profitability by quarter: http://j.mp/13zx97Z for the last 5 years.
Also, note that Amazon's initial business plan was such that it would not turn profitable for quite a few years, instead focusing on sales-growth. IIRC, they turned profitable around 2002.
I was being hyperbolic. Sorry. Amazon has made a minuscule amount of profit. Their numbers are horrible. I can't believe their shareholders put up with them.
Their most profitable year, 2010, they only made $1.15-billion of profit off of $34-billion in revenue.
In 2011 they made only $631-million off $48-billion.
> All exams are proctored using national proctoring standards. We have access to 4,500 physical proctoring facilities and are working with online proctoring institutions.
Does this mean it won't be available outside the US ("national proctoring standards")?
Or does this mean appearing at prometric-style centers for the tests? I for one do not love taking tests in the alien environment of such centers (especially computer-science related tests), from my experience with various certifications.
The Ruby language changed between 1.9 and 1.9.1, so a new package name had to be created.
If 1.9.1 was just called "1.9" it would break all of the packages in Debian that depend on whatever language features were different between 1.9 and 1.9.1.
"ruby1.9.1" in Debian 7.0 provides version 1.9.3.194.
I love these kind of stories. Such stories fills me up with an immense sense of appreciation for scientists/philosophers/thinkers from the post-middle-ages.
If you have not peaked into it yet, the way Dr. Plesser explains concepts and bridges them with the historical advances leaves a lasting impression. I wish we had classes like this back in school.
Also, if you like the "Introduction to Astronomy" course, there's a follow-up (although from a different university, Caltech) coming up: "Galaxies and Cosmology": https://www.coursera.org/course/cosmo
It's part of a comprehensive course in modern physics, all taught by susskind, and all on that same youtube channel. There's classical mechanics, quantum mechanics, the aforementioned cosmology and more iirc. He's a great teacher, it's amazing that you can just dial up tens of thousands of dollars worth of education like this.
