The C++ Standard Library: Recap

The final 7 sections of The C++ Standard Library by Josuttis required lots of attention, but I am glad to have read this book cover to cover.

This book is worth purchasing for Chapter 8 alone in its description of the function objects. The concept of stateful function objects is a powerful idea and can be used in conjunction with the standard library algorithms to produce some powerful behavior.

Function objects provide a great introduction to the algorithms section in that many of the algorithms require function pointers or objects as arguments to execute on the item. Items in a container are typically modified using beginning and end iterators, or even pointers to contiguous arrays of memory.

After the algorithms section, a special containers section described the bitset container. This is a container that will come in handy during protocol development at some point, but whether operations on the bitset are faster than simple C binary operations would be interesting to test.

In the numerics section, the valarrays section proves to be a very interesting way to perform operations on vectors and matrices, and I'm surprised it's not used more often.

To make code internationalized, locales, character traits, and facets were described. I guess this doesn't mean too much to me at the moment since I only operate in the default C locale, but this is a good section to know when developing software for just about anywhere else in the world!

I am surprised the allocator section was so short. The section really only contained an instance of an allocator object along with several built-in C++ functions dealing with memory that has not been allocated (pointer to pointers) or constructed (actual objects). Maybe I will need to get my memory fix through some boost documentation or the books by Scott Meyers.

I also thought that it was interesting to know that folks in Nepal use 10.00.000 to represent 1,000,000.

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

Best Documentation of a Free Software Package

One oft overlooked artifact in software development is the documentation. An API that is not well documented is no API at all when time is of the essence. That's why I think it is important to discuss some of the tools I have used and their documentation. AutoIt - I love how you simply press F1 within the AutoIt editor and boom, the reference to the particular syntax or function pops up in the help window. This help file is well written, self-contained, and chock full of examples that can be opened up in the editor right from the help, a fantastic symbiotic relationship. After installing AutoIt and giving it a try using their examples, I was able to create client/server scripts, GUI scripts, and window management scripts in no time. Overall, AutoIt is tops in this competition. A+ MySQL - At the bottom of each page of documentation that discusses a particular statement, users are able to post comments containing code snippets for that particular statement. This is great..

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.
