Custom CSS Filters with GLSL Shaders

Rodrigo Silveira — Wed, 17 Apr 2013 22:17:01 +0000

Yesterday I got to the chapter of my book where I was to write about CSS Shaders. Since up to that point I had only heard about them, I had to go out and so my research on it. Turns out they're not even called that anymore... Since the feature was merged with the CSS filters spec, they're all called just that now.

I made the full switch to Git about 6 months ago, and I see no reason to ever go back to SVN. For the most part, everything is going great, and I've had no problems adapting. The idea of branches, fast forwarding, etc. is pretty intuitive and easy to follow.

A Paper on Extreme Programming

Rodrigo Silveira — Tue, 10 Apr 2012 03:11:44 +0000

Extreme Programming is a software development method created by Kent Beck in 1996. It is considered an incremental development method, meaning that a project is completed in small, incremental cycles, where more functionality is added to the software as the project progresses.

Two fundamental differences between computers and humans are that computers don’t forget, and computers don’t vary in the least when repeating an instruction. Thus, when a computer program is executed for the millionth time, the computer still remembers what to do, and does so exactly the same way as it did the first time.

A quick challenge for the C programmers out there wanting something to do this week. The challenge is to complete each function skeleton using only straightline code (i.e., no loops or conditionals) and a limited number of C arithmetic and logical operators. Specifically, you are only allowed to use the following eight operators: ! ~ & ^ | + >

The plugin takes C, C++, C#, Java, Javascript, or PHP source code in plain text inside any HTML tag(s) that you specify, and formats it adding line numbers, syntax highlighting, and preserving spacing. You can change the theme through a very basic CSS style sheet file.

Rodrigo Silveira — Fri, 18 Nov 2011 08:41:17 +0000

My final project for one of my C++ classes is a game of Sudoku. The program, to be written in C++, must be able to read a board from a text file, allow the human player to play the game, with simple rules enforced, as well as allow the user to save the game to an external text file. For extra credit the professor challenged us to write the AI to solve the game. My goal is to get the extra credit, but later to convert the code to Javascript and make a Google Chrome App out of it. Sounds like a fun challenge.

Binary Matrix Multiplication

Rodrigo Silveira — Wed, 26 Oct 2011 05:34:02 +0000

A simple and efficient way to multiply two or more matrices, but more specifically, a binary matrix (also known as zero-one matrix). This code has many uses, but was written specifically to solve the problem of determining whether a given binary matrix is transitive.

This is the third exploration in CS 238 (Discrete Math 2) that Brother Neff assigned. So far this is the easiest exploration I've seen since I started BYU-Idaho. All that we need to do is analyze a bunch of 2x2 and 4x4 matrices, and determine if they are symmetric, antisymmetric, asymmetric, reflexive, nonreflexive, irreflexive, and transitive. Most of the code is already provided (as always, the code is all C++). All we need to do is implement the functions that check for those properties in the matrices. Extra points are awarded for efficient, non-redundant code.

My initial post on CS 238's exploration 2. This exploration is all about calculating a home loan, and printing out an amortization schedule. While not as simple as Brother Ercanbrack's CS 213 mortgage calculator apps, this exploration is not nearly as complicated as RSA or most other explorations Brother Neff assigned in Discrete Math 1.
