This isn't a syntax error in python, but I wish it was!
This simple typo can cause subtle hard to find bugs. 😡

Canada's Housing Bubble Will Burst
Canadian home sales fell the most in five years last month. That didn’t stop an increase in prices, which were up 18 percent nationwide from a year earlier. When you consider that most houses are leveraged assets, this represents huge gains for homeowners.

While leverage can help boost performance on the way up, it becomes very dangerous on the way down. Leverage can turn even the best investments into poor ones when things go wrong, as losses are amplified. Equity can get wiped out pretty quickly on an overleveraged asset.

Canadian real estate has been on fire for years. The housing price data there has made the U.S. real estate market during the boom of the mid-2000s look mild.

The Federal Reserve Bank of Dallas puts out a global housing price index for more than 20 countries every quarter. Using this data, I looked at the real house price index data for Canada and compared it with the same data in the U.S. going back to 1975.

No, Really – Programming is Hard and CS Flipped Classrooms are Complicated: ITICSE 2016 Award-Winning Papers
I only recently started digging into the papers from the ITICSE 2016 conference (see Table of Contents link at ACM Digital Library here). There were two papers that caught my attention.

First, the best paper award went to one of my former PhD students, Brian Dorn: An Empirical Analysis of Video Viewing Behaviors in Flipped CS1 Courses, by Suzanne L. Dazo, Nicholas R. Stepanek, Robert Fulkerson, and Brian Dorn. Brian has this cool piece of technology where students can view videos, annotate them, be challenged to answer questions from specific places, and have discussions. They used this for teaching a flipped CS1 class, where students were required to watch videos before class and then engage in more active learning opportunities in class. The real trick, as you might imagine and that the paper goes into detail on, is getting students to watch the video. I liked both the techniques for prodding students to watch videos and the fascinating results showing the relationship between watching the videos and learning.

ITICSE 2016 recognized two “commended” papers this year. I haven’t found the listing of which papers they were, but I did learn that one of them is Learning to Program is Easy by Andrew Luxton-Reilly. I enjoyed reading the paper and recommend it — even though I disagree with his conclusions, captured in the paper title. He does a good job of exploring the evidence that programming is hard (and even uses this blog as a foil, since I’ve claimed several times that programming is hard), and overall, is a terrific synthesis of a bunch of computing education papers (40 references is a lot for a six page ITICSE paper).

Unionfs: A Stackable Unification File System
This project builds a stackable unification file system, which can appear to merge the contents of several directories (branches), while keeping their physical content separate. Unionfs is useful for unified source tree management, merged contents of split CD-ROM, merged separate software package directories, data grids, and more. Unionfs allows any mix of read-only and read-write branches, as well as insertion and deletion of branches anywhere in the fan-out. To maintain unix semantics, Unionfs handles elimination of duplicates, partial-error conditions, and more. Unionfs is part of the larger FiST project which includes the Wrapfs wrapper stackable file system.
