During teaching, there is a fascinating (and unfortunately common) problem: Students are VERY reluctant to suggest an answer, for fear that they might be wrong.
Salman Kahn, noticed this phenomenon after he started doing videos for his niece and nephew: (I’m paraphrasing) “The last thing they needed was for me to be there expecting an […]
In my last post on Information Flow, I noticed that some flows are more informative than others. I used a switch statement for my illustrative example of that observation. But, from my experience as a software developer, I have a small aversion to switch statements. Usually, when I feel compelled to use one, it’s because […]
I would like to evaluate whether or not Gold functions better than paper as a currency. This subject comes up, because of an engaging argument that I had last night about the U.S. Constitution and it’s purview of the monetary policy of the U.S. government. In particular, though the Constitution does not define what Money […]
This post is part of a seres: The Good IR (BasicBlocks and control flow instructions) The Good IR: Other Control Flow Structures The Good IR: Instructions and Values The Good IR: Reporting Semantic Errors via Type Checking The Good IR: Multiple Returns —- After parsing, each function can be represented as a ControlFlowGraph of BasicBlocks. […]
If you’re gonna be in the software industry. You have to communicate, not only through code but also through email, forums, IRC or IM. It’s not so important that you be a fast typing in order to bang out code really fast. Rather, you should be a fast typing so that it doesn’t hold you […]
I’ve just finished reading Phillip Greenspun’s experience report, Teaching Software Engineering, which details a project course in building Web Services. Even though I personally, hate the Web’s architecture (but that’s a rant for some other time), it still remains as THE most influentential and convenient place to showcase one’s work. It’s also convenient for shopping, […]
When I was writing last post about information flow terminology, I noticed something interesting: when knowledge of control flows are used to determine the values of variables, some branches yield more information than others. Previously, I had only considered the binary if-then-else branch. Today, I shall examine a switch-case statement, which exhibits asymmetric information flow.

Ideal Key Layout
For a long time, I have hated the layout on all keyboards I’ve ever laid hands on. It’s not just that I prefer Dvorak to Qwerty; it’s that the slanting of the rows causes an awkward bending of the left wrist, that the space key is far too large when you […]
Somehow, I feel that I betray my cyberpunk heritage because I’ve recently found it entertaining to don extravagant neckwear. But, my recently conducted anthropological expedition has revealed evidence that I am in fact upholding a veritably geek tradition.
Information flow is about tracking the flows of information within a computer program, i.e. what values influence other values as the program executes. Denning and Denning looked at this problem in the late 1970’s [1, 2] and distinguished between flows that occur due to a data dependence (such as assignment) and flows which occur due […]
