Curl to call RESTful API

In this post I will perform some basic interactions with a RESTful service running on ASP.NET written in C#. I will access the RESTful server using the cURL (a.k.a. curl) command line interface. On a future post I will access the curl API using the C# programming language to illustrate its use. Continue reading “Curl to call RESTful API”

prog-languagesI have dedicated my professional career to different disciplines (i.e., graphics, software engineering) within Computer Science. In this blog entry I would like to summarize some observations regarding computer languages. At different stages in life (e.g., college, work, self study, and business owner) most developers are required or just decide to learn different programming languages. An issue that frequently comes up with project managers is: “Knowing and using multiple programming languages is better or worse for a software developer?” In this blog entry I would like to provide some insights on how to respond to this question.

Coding Exercise

cubeEarlier this week I was talking with a colleague about sites that are becoming quite popular with software developers (e.g., HackerRank https://www.hackerrank.com). The format is quite similar between sites. A problem is described. You need to write correct code to solve it.

All have a window in which you can write the necessary code. Most of the constraints for the problem are described. The better sites provide some sample data sets to test your solution. Continue reading “Coding Exercise”
