By optimizing network latency (HTTP Request Size)

Prologue
[Detail of the technology / concept being used in the tip if required]

Why
As static content like images, CSS, JS don’t need to be accompanied by cookies, as there is no user interaction with these resources.

How
Serve static content from a domain that doesn’t serve cookies

Exceptions
o        Using this technique for pages serving fewer than 5 resources, setting up an extra domain for this purpose would be an overhead
o        Serving early loaded external JS files from cookie less domain can introduce overhead as most browser stop downloading other external resources until external JS file is downloaded, extracted, parsed and executed.

Recommendations
Use this technique for any page that serves more than 5 static resources

Bugs Management in Agile Project

Agile has a refreshing approach to bugs, especially when contrasted with traditional waterfall practices. Historically, teams would postpone bugs to a stabilization phase. This stabilization phase was long and tedious, typically with high stress and long hours. Agile, on the other hand, promotes the following thought processes: Carrying bug debt is unhealthy and sometimes, even destructive. We should fix bugs, not track them. A feature isn't done until the bugs are fixed. Quality is part of the overall cost. Bugs are prioritized against new features. A bug needs to be more important than the next new feature.

Most are discovered and fixed immediately by the team as a part of feature development: some a few days later, others not until long after a story is considered &quo
