  C++ for the Real-Time Web

C++? Why on Earth? C++ seems like one of the least likely languages to write a web application in. C++ is associated with complexity, both with language design and the need to manually manage memory. Programming in C++ unleashes a whole class of bugs associated with memory corruption and memory allocation. This is a trade off for giving more power to the developer along generally being much faster than equivalent programs in languages such as Python or Ruby. Real-time Web as a Use Case Making...

  What Happens When Apps Go On Sale?: Revenue Up 22% On iPhone, 29% On Android

In a new research report from Distimo, the app store analytics provider examined two different ways that allow mobile developers to get a bump in both their download numbers and revenue. One way, which is within the developers’ control, is putting the app on sale. Within the first day, iPhone developers see an average increase of 41% in revenue using this method, and see revenue increases of 22% by the sale’s end. Android apps, however, rose just 7% on day one, but closed ou...

  On Employers, Portfolios, Commitment, and Cake

You might know from experience that planning for a wedding is no simple feat. In the months leading up to our wedding, my then fiancé and I spent countless hours planning and making sure that no detail was overlooked.

We were impressed by her references and experience, and our initial conve...

   Python – parallelizing CPU-bound tasks with multiprocessing

In a previous post on Python threads, I briefly mentioned that threads are unsuitable for CPU-bound tasks, and multiprocessing should be used instead. Here I want to demonstrate this with benchmark numbers, also showing that creating multiple processes in Python is just as simple as creating multiple threads. First, let’s pick a simple computation to use for the benchmarking. I don’t want it to be completely artificial, so I’ll use a dumbed-down version of factorization...

  SIEM Big Data Visualization [03]:Graph-Based SIEM Log Analysis Dashboard

Program Design Purpose: The purpose of this program is to develop a Graph-Based SIEM (System Information and Event Management) dashboard that visualizes network communication patterns by processing and analyzing logs from IDS, firewalls, host computers, and other security devices. This dashboard will help security analysts quickly identify and investigate potential threats by using a Cytoscape-style Node-Edge graph for intuitive data representation. The program is an angular plug in which can i...
