Your Mouse is a Database

Web and mobile applications are increasingly composed of asynchronous and realtime streaming services and push notifications.

Among the hottest buzzwords in the IT industry these days is "big data," but the "big" is something of a misnomer: big data is not just about volume, but also about velocity and variety. The volume of data ranges from a small number of items stored in the closed world of a conventional RDMS (relational database management system) to a large number of items spread out over a large cluster of machines or across the entire World Wide Web.

Managing Technical Debt

Shortcuts that save money and time today can cost you down the road.

In 1992, Ward Cunningham published a report at OOPSLA (Object-oriented Programming, Systems, Languages, and Applications) in which he proposed the concept of technical debt. He defines it in terms of immature code: "Shipping first-time code is like going into debt." Technical debt isn't limited to first-time code, however. There are many ways and reasons (not all bad) to take on technical debt.
