I took a Computational Finance midterm over the weekend on Coursera. I’ve taken a few Coursera classes before — they had quizzes, problem sets, programming assignments, essays — but none of them had a midterm or final exam. It’s the first academic exam I’ve taken in at least a couple of decades, and the first exam ever in which — because it was online — I was able to participate in the company of my life partner, Wild Turkey. Here’s my result: I lost the one point on this question right here: If you understand the question, it’s obvious which one of the four I missed, but it may not be obvious what the right answer is. It wasn’t to me, anyway. My wife asks, “Did you see the grading curve?” “No, but when you score 149 out of 150, you leave it to others to worry about the curve.” Read more →

Coursera Recommendations
Coursera‘s been around long enough now that some classes are being offered for a second time, including a couple that I’ve taken and recommend: Modern & Contemporary American Poetry, taught by Al Filreis at Penn Social Network Analysis, taught by Lada Adamic at the University of Michigan Read more →
Screw Economics
One of the classes I’m taking on Coursera is Principles of Economics for Scientists, taught by Prof. Antonio Rangel at Cal Tech. First of all, it’s a great class. Rangel has a real passion for the material and he’s provided extra resources to accomodate online students, many of whom probably don’t have the math background of the average Cal Tech student. He’s from Madrid, so his pronunciations and mannerisms are different, like the gesture below, which I captured from one of the video lectures. He was explaining how something or other would increase our understanding of economics and he punctuated the word “understanding” by pointing at his head with two fingers. I don’t know what this gesture means in Spain, or if it means anything at all. Probably he knows what it means in America, but as I said, he’s passionate about the material and I think he loses himself… Read more →

More People I’m Sick Unto Death Of

Poems I’ve Read Recently and Liked
I’ve been reading a lot of poetry as part of the Modern & Contemporary American Poetry class on Coursera. One of the things I like about the class is that the video lessons are done a little differently than other Coursera classes I’ve taken. Rather than recorded lectures, the videos consist of the instructor, Al Filreis, leading a small group of Penn students in close readings of selected poems. Anyway, here are a few of my favorites so far: I dwell in Possibility by Emily Dickinson Tell all the Truth but tell it slant by Emily Dickinson The Brain within its Groove by Emily Dickinson Danse Russe by William Carlos Williams This Is Just To Say by Willim Carlos Williams A Supermarket in California by Allen Ginsburg Lines for an Abortionist’s Office by Ruth Lechlitner Incident by Countee Cullen These next two, both by Richard Wilbur, I want to single out as being particularly… Read more →
The Lives of Julia and Paul
David Henderson says — accurately, I think — that Mitt Romney’s “47 percent” remarks can be paraphrased as “People who are dependent on government will vote for the candidate who credibly (to them, at least) promises to keep the programs that have created that dependence.” Do you think President Obama disagrees with that? He doesn’t. If you think he does, please see The Life of Julia on the president’s web site. It lays out a “typical” woman’s cradle-to-grave dependence on government assistance and describes how Obama will keep those programs going while Mitt Romney won’t. The most insulting thing about it is that as you read about Obama funding this and Obama funding that, it sounds like he’s doing it all out of his own goddamn pocket. What a prince! There’s no acknowledgement that Obama is taking from some and giving to others, and that all of Julia’s “free” stuff… Read more →
The Obama Bounce Fades
And through it all, there is no presidential leadership. He’s too busy raising money to run ads so he can tell us what a great leader he is. Everywhere we see, in ruins, Obama’s plans for our country. His foreign policy has encouraged revolutions that have brought our worst enemies to power in the Middle East . . . His education reforms have no teeth and he sits by passively as they are challenged by his own local teachers union. Credit much of the quick end to his bounce to Romney’s ads which, right off the bat after the Democratic Convention closed, rapped Obama for trying to convince us that we are better off than we were four years ago. Obama’s campaign essentially poses the question: What will you believe — your own eyes or my speeches? — Dick Morris Read more →
Everyone in America Can Go to College
This morning I heard President Obama call for universities to lower their tuition rates so that “everybody in America can go to college.” I am virtually certain that the President is not stupid enough to think that if tuition rates fell to zero, there would magically be enough room in the colleges for everybody in America. So I’ve got to believe that he’s purposely saying stupid things in order to appeal to stupid voters — the sort of voters, in other words, who probably don’t belong in college. — Steven Landsburg Read more →
The World’s Greatest University
It’s move-in weekend at UC Berkeley, the world’s greatest university . . . Saul Perlmutter, who just won the Nobel Prize in Physics, is teaching an undergraduate seminar on physics and music this year. How many schools even have Nobel Laureates on the faculty? Of those that do, how many of them teach small classes for freshmen and sophomores? Ivy League schools, with the exception of Harvard, are coasting on their reputations. When’s the last time you heard of an enterpreneur from Dartmouth or Brown or Yale? Stanford is great in engineering and business but limited in other areas. Also, top professors at private schools would rather piss on a spark plug than traffic with undergrads. That said, the University of Southern California football season starts Sept. 1 against Hawaii.

Another Guy Who Didn’t Get the Memo on the American Dream
Kennedy Odede grew up in Kibera, a slum in Kenya where more than one million people live in an area the size of New York City’s Central Park without sewage systems, roads, or access to basic health care and education. And on Sunday, May 27th, he stood proudly before his graduating class with honors, and gave the commencement address. He became the first person from Africa’s largest slum to graduate from an American University. — From an African slum to Wesleyan University – The Daily Nightly Sounds like another guy who didn’t get the memo that America is “no longer the land of opportunity” and “the ‘American dream’ is a myth.” Read more →
The Person Who Says It Can’t Be Done Is Interrupted By The Person Doing It
In his latest book, The Price of Inequality, Columbia Professor and Nobel laureate Joseph Stiglitz examines the causes of income inequality and offers some remedies. In between, he reaches some startling conclusions, including that America is “no longer the land of opportunity” and “the ‘American dream’ is a myth.” — The ‘American Dream’ Is a Myth: Joseph Stiglitz on ‘The Price of Inequality’ “If there is anybody at all who has a dream, then they can definitely make it happen,” she told WBTV. “There are no excuses.

Ruby on Rails for Rubes
The biggest headache in software development is that most programmers can’t program and don’t want to learn anything. I recently finished up a MOOC called Software Engineering for SaaS, offered by UC Berkeley through Coursera. For a modest investment of a few hours a week for five weeks, I learned some Ruby on Rails — a well-designed platform and a lot of fun to work with — as well as tools like GitHub, Cucumber, RSpec, SimpleCov and Heroku. Over 50,000 students from 150 countries signed up for the class. According to a final email from the professors, about 10,000 students attempted at least one assignment or quiz. Or to look at another way, 80 percent of the students gave up without even trying. Approximately 2,000 students, or 4 percent, completed all four of the assignments and the three quizzes. One of the enrollees who gave up without trying is a… Read more →
Crosstown Cup: USC 8, UCLA 3
The Crosstown Cup was on the line Saturday night. The USC and UCLA hockey teams faced off at Anaheim Ice and the Trojans dominated pretty much as I expected. It was also Senior Night — the last game of the season. One of the Trojans players is graduating with a doctorate in education, one kid is getting an MBA and two kids are graduating with a bachelor’s degree in petroleum engineering. As scholar-athletes, they’re pretty darn good scholars. As athletes . . . let’s say that they were somewhat less good than my kid’s 18-and-under roller team from last season. Speed, puck control, rink awareness — all limited at best. They were a lot better than UCLA though. The Victory Bell was in attendance. Something I didn’t know is that the Victory Bell is really loud if you’re right next to it. And by “right next to it,” I… Read more →
Underrepresented Minorities in the UC
The University of California is prohibited by law from considering race in the admissions process, but they are allowed to identify certain ethnic groups as “underrepresented minorities.” Here are some freshman enrollment numbers at UC Berkeley for Fall 2011. The first four groups on the list are considered underrepresented; the others aren’t. Ethnicity 2011 Fall African American/Black 130 Mexican American/Chicano 325 Other Hispanic/Latino 150 Native American/Alaskan Native 33 Pacific Islander 11 Chinese 936 Filipino 108 Japanese 68 Korean 250 Other Asian 45 South Asian 324 Vietnamese 142 Read more →
Chinese Parents vs Western Parents
Chinese parents can order their kids to get straight As. Western parents can only ask their kids to try their best. Chinese parents can say, “You’re lazy. All your classmates are getting ahead of you.” By contrast, Western parents have to struggle with their own conflicted feelings about achievement, and try to persuade themselves that they’re not disappointed about how their kids turned out. — Amy Chua, Battle Hymn of the Tiger Mother Read more →
Don’t Check Asian
Asian kids are putting a different race on their college applications to boost their chances of getting into the top schools. Lanya Olmstead was born in Florida to a mother who immigrated from Taiwan and an American father of Norwegian ancestry. Ethnically, she considers herself half Taiwanese and half Norwegian. But when applying to Harvard, Olmstead checked only one box for her race: white. — Some Asians’ college strategy: Don’t check ‘Asian’ – Yahoo! News That’s a rather modest strategy. Identifying yourself as white does give you a little bit of a boost but to really improve the odds, I’d advise everyone to go ahead and check the Black or Hispanic box. Or Eskimo. Eskimos are kind of Asian-looking. Princeton sociologist Thomas Espenshade examined applicants to top colleges from 1997, when the maximum SAT score was 1600 (today it’s 2400). Espenshade found that Asian-Americans needed a 1550 SAT to have… Read more →
Indonesian Kids Appreciate the Value of Education
The conventional wisdom in America is that you have to be rich to get a good primary education. The real problem is that American kids will not cross a collapsed suspension bridge to get to their school on the other side of the river, like Indonesian kids will . . . Read more →
I’m Addressing the Shortage of Women in Technology
I keep hearing that there aren’t enough women in technology, like this is a problem. The most obvious explanation is that women don’t want to work in technology. If they want to work in other fields, fine. If they want to raise their kids, even better. I did some tutoring for a girl taking AP Computer Science. She’s a junior in high school and wants to be a veterinarian. Afterwards, she told her dad, “If I decide not to be a veterinarian, maybe I’ll be a programmer.” Don’t let it be said that I’m not doing my part to address the shortage of women in technology, even though I think it’s baloney . . . Thus spoke The Programmer. Read more →
