Fun with MySQL + PHP

Lately, I've been getting a lot of requests to build websites driven by lots of data, so I've been reading heavily into MySQL and PHP. I've been relying "Beginning PHP and MySQL: From Novice to Professional, Third Edition" by W. Jason Gilmore. I was concerned with his use of connecting to MySQL with a plaintext user name and password, so I went through a few tutorials online:

[hvassing.com]

[studiolounge.net]

and the SQL reference manual: [dev.mysql.com]

Of course, they did the same thing. I'm working on trying to implement an SSL solution to login, but unfortunately I think it'll require an X.509 certificate.

Software Design Principles - SOLID

The SOLID software design principles weren't called SOLID while I was in grad school, but the concepts were there in my Object Oriented Design course. They're worth mentioning here, primarily because I think once you start coding and become dangerous, it's one of the best ways to stay organized once you incorporate it into your daily coding routines, and it even changes your way of thinking for the better: https://en.wikipedia.org/wiki/SOLID

Matlab and MySQL

I had a lot of data in a MySQL database that I wanted to analyze. I had a copy of Matlab, so I figured the best way to look at this all would be to plot this data and use some GUI elements to go through various combinations. After some Googling, I found this database connector that seemed to do the trick. I downloaded the files, configured mex to use MSVC 2008, built the connector, then I was able to successfully connect over the network! I ran into two problems, though: The connector does not support fetching columns of type TIMESTAMP, and With the magnitude of data (about 180k rows), access times were really slow. I was able to solve problem #1 by changing my columns to DATETIME, which was supported. I'm still trying to figure out problem #2. It may come down to importing all the data directly into Matlab.

Rehashing C++ With Smart Pointers

Though I have seldom cared about using smart pointers these past three years (primarily because I work mostly with C, which can't support truly encapsulating smart pointers), I have tried to rehash my knowledge with Andrei Alexandrescu's tutorial here: [informit.com] I am absolutely astounded by the attention to detail in this article for something so simple as a single class with overloaded operators. C++ is a language that is not for the faint at heart, so this sort of article helps to navigate through the memory management limitations of C++. I should consider buying Andrei's book with the Eckel book to go with my Stroustroup and Musser books! Where's my amazon wish list...
