C++: enable_if

CodeProject, C++, knowledge 1 feedback »

A few weeks ago I wrote an entry on SFINAE[^], and I mentioned enable_if. At that point I had never been able to successfully apply enable_if. I knew this construct was possible because of SFINAE, however, I was letting the differences between SFINAE and template specialization confuse me. I now have a better understanding and wanted to share my findings.

Alchemy: BitLists Mk1

CodeProject, C++, Alchemy, design Send feedback »

A continuation of a series of blog entries that documents the design and implementation process of a library. The library is called, Network Alchemy[^]. Alchemy performs low-level data serialization. It is written in C++ using template meta-programming.

At this point, I was still in the make it work phase of implementation. However, I learned quite a bit from experiencing the progression of design and multiple implementations. So much that I thought it was valuable enough to share.

After the initial creation of the Datum type, it was relatively simple to abstract the design and implement the Bit-Field. object. The next step was to combine the collection of BitField objects into a single group that could be statically-verified as type-safe. This was also relatively simple. Again I just had to model the implementation of the message structure. I called this collection a BitList. Primarily to differentiate it from the std::bitset.

Alchemy: BitField

portability, CodeProject, C++, Alchemy, design Send feedback »

This is an entry for the continuing series of blog entries that documents the design and implementation process of a library. This library is called, Network Alchemy[^]. Alchemy performs data serialization and it is written in C++.

After I had proven to myself that serializing data with a template meta-program was feasible, I started to research what features would be required to make this a useful library. After the fundamental data types, I noticed that sub-byte access of bits appeared quite often in network packet formats, bit-fields. I have also worked in my share of code that implemented these packet formats using the bit-field feature in C/C++.

I decided support for accessing values at the bit-level needed to be a feature of Alchemy. I will explain why, as well as show my first attempt to make this work.

What Is a Software Architect?

general, leadership, communication, CodeProject, engineering Send feedback »

There is so much confusion surrounding the purpose of a Software Architect and the value they provide and what they are supposed to do. So much so, that it seems the title is being used less and less by companies and replaced with a different title such as principal or staff. I assume this is due to the perception there must be a way to distinguish a level above senior, which is handed out after only about three years of experience.
