Segmented Map, a Compromise Between Flat Map and std::map

This article provides and implementation of a container, called segmented map, which is almost as fast as flat map in random access and enumeration of elements and close to std::map in insertion of elements. The source code is written in C++17 and can be compiled in any C++17 compiler. Benchmarks with the “int-double” and “string-string” key-value pairs are provided for … Read More

An Optimal Wagner-Fischer Algorithm For Approximate Strings

The Levenshtein distance is an efficient metric widely applied to evaluate the similarity between literal strings and other 1D sets. In this article, the optimal Wagner-Fischer algorithm for the Levenshtein distance computation and its implementation, are thoroughly discussed, by an example. The code samples in Python and NumPy demonstrate the similarity of literal strings evaluation, based on the Levenshtein distance … Read More

Rethinking the Web – Part 1

What would the web look like if the pioneers had the tools and tech we have today? What would the OO software look like if we used the OO paradigm championed by the developers of the web? Why has software development become so complicated? This series of articles answers these questions, and presents an alternate approach to how we design … Read More
