Black Versus White Boxes

Gödel's Lost Letter and P=NP

cauer

Wilhelm Cauer was a German mathematician and engineer who worked in Gttingen and the US between the two world wars. He is associated with the term “black box,” although he apparently did not use it in his published papers, and others are said to have used it before. What Cauer did do was conceive a computing device based on electrical principles. According to this essay by Hartmut Petzold, Cauer’s device was markedly more advanced and mathematically general than other ‘analog devices’ of the same decades. He returned to Germany in the early 1930’s, stayed despite attention being drawn to some Jewish ancestry, and was killed in the last days of Berlin despite being on the Red Army’s list of scientists whose safety they’d wished to assure.

Today Ken and I wish to talk about black boxes and white boxes, no matter who invented them, and their relation to computing.

Married ladies can have crushes, too

write meg!

. . . Well — book crushes, that is.

My earliest relationships weren’t with actual boys, friends. I didn’t manage to catch the eye of the cute kid in math class or Peter Brady or even Daniel, the first boy to earn a sappy valentine in second grade.

They were with book characters.

LoveI fell for bookish leading men long before I dared to express my feelings to any real-life ones. Relationships in my favorite novels taught me about relationships in general, especially in those impressionable teen years, and I feel like I’m a better reader — and person — because of it.

Though I am, in fact, a happily married lady, my devotion to my flesh-and-blood husband does not negate the underlying passion I can feel for literary men. We’ve all been there, right? Sometimes you can’t help but fall into a bottomless pit of yearning for some…

The Form Rejection Letter Decoder Thingy

The Brevity Blog

A helpful blog entry from Brevity’s managing editor Sarah Einstein. Sarah will be talking about rejection, acceptance, and writing as part of the panel “Getting Short-Form Nonfiction to Readers: A Publication Panel” on the Friday morning of AWP Seattle:

Every couple of weeks, a writer-friend sends me an email or a Facebook message with the text of a rejection letter in it, asking me to help them decode it. Most often, they want me to help them figure out how close they got to being published, which is an impossible task. I couldn’t even tell you that if it was a submission to Brevity… ultimately, either we took the piece or we didn’t. We do have tiered rejection letters. If you got our “close but not cigar” rejection, you should probably turn around and submit that piece to five other places right away because we thought pretty hard…

What I Learned by Flipping the MOOC

Steve Blank

Two of the hot topics in education in the last few years have been Massive Open Online Courses (MOOC’s) and the flipped classroom. I’ve been experimenting with both of them.

What I’ve learned (besides being able to use the word “pedagogy” in a sentence) is
1) assigning students lectures as homework doesn’t guarantee the students will watch them and 2) in a flipped classroom you can become hostage to the pedagogy.

Here’s the story of what we tried and what we learned.

MOOC’s – Massive Open Online Courses
A MOOC is a complicated name for a simple idea – an online course accessible to everyone over the web. I created my MOOC by serendipity. Learning how to optimize it in my classes has been a more deliberate and iterative process.

The Prosecution That Isn’t Happening

The Baseline Scenario

By James Kwak

People keep asking why no senior executive has gone to jail for the misdeeds that produced the financial crisis—and cost the United States more than $6 trillion, or $50,000 per household, in lost economic output. The usual answers are that no one did anything wrong (oh, come on) or, more realistically, that it’s too hard to convict individuals in complex financial fraud cases.

At the same time, however, the U.S. Attorney’s office for the Southern District of New York—the district that includes Wall Street—has amassed a 79-0 record in insider trading cases, including yesterday’s jury verdict against Mathew Martoma, a trader at the hedge fund firm SAC Capital Advisors. In Martoma’s case, he obtained confidential information about a clinical trial for a drug being manufactured by two pharmaceutical companies and, according to the jury, convinced his boss, Steven Cohen, to unload the firm’s positions in…

Stop Saying “That’s So Gay!”: 6 Types of Microaggressions That Harm LGBTQ People

Psychology Benefits Society

Sad Asian teenage boy

By Kevin L. Nadal, PhD (Associate Professor of Psychology, John Jay
College of Criminal Justice – City University of New York)

When I was a little kid, I used to hear my brothers, cousins, and friends say things like “That’s so gay!” on a pretty regular basis. I would usually laugh along, hoping with all my might that they didn’t know my secret.  My parents and other adults in my life would tell me things like “Boys don’t cry” or “Be a man!” which essentially was their way of telling me that being emotional was forbidden or a sign of weakness.

When I was a teenager, there were a few boys at my high school who ridiculed me, almost everyday. When I walked by them in the halls, they called me a “faggot” or screamed my name in a flamboyant tone.  I learned to walk by without…

Comcast and Time Warner Cable: Forget TV, it is all about broadband

Gigaom

If it is allowed to gobble up its number two rival, Time Warner Cable, Philadelphia-based Comcast will become the largest broadband provider in the United States, and perhaps the largest outside China. The two companies together will control about half of what is called triple-play services — video, voice and internet — in the U.S. The two companies together would have about 33 million broadband connections that brought in about $18 billion in broadband revenue during 2013.

Back in November 2013, my colleague Stacey Higginbotham laid out a persuasive argument about why the cable consolidation is all about broadband. She wrote:

So the cable industry, if it can consolidate, gets access to the most important pipe coming into people’s homes (after power and water) and the fewer cable companies there are, the more unified the rate structure might appear. So today Comcast has a cap, but Time Warner Cable doesn’t
