2019-01-25 Friday - The New Yorker article, The Friendship That Made Google Huge

I thoroughly enjoyed reading this article - which provides an interesting insight into some of the early history of Google - and work that has been foundational to many advances for many technology companies.

The Friendship That Made Google Huge

(Coding together at the same computer, Jeff Dean and Sanjay Ghemawat changed the course of the company—and the Internet.)

2019-01-22 Tuesday - .NET Exception Handling

A recent question came up within a .NET engineering team regarding exception handling - and wrapping Try/Catch logic around Web API controller logic was proposed. This posting is to organize some resources that offer an alternative approach - and highlights some concerns around possible exception handling anti-patterns.
