Printing an object's properties for debug purposes

Quite often, we override the 'toString()' method of an object to print its properties. But there are a number of reusable utilities that can be used for the same.

In Java, the popular Apache Commons Lang3 package contains a class called ReflectionToStringBuilder  that has static overloaded methods 'ToString()' to print all fields using reflection. You can also specify a few formatting options and the fields to exclude.

Another option is Java, is to use the JSON libraries to print the object as a json string. The Google librarly Gson can be used to print (or pretty print) an object as a json string.

In .NET, you can either use the ObjectDumper library or you can use the object json formatter - newtonsoft JSON library

Ruminating on staffing for 24*7 support

Many production applications need 24*7 support. So how many resources do we need to support an application round the clock? The below simple calculation can help - 

Assume each resource works for 40 hours in a week. 

In one week, you have to cover 24*7 = 168 hours / week.

So total FTE = 168/40 = 4.2 FTE

To accommodate for vacation and sick leave, we can round it to 5 FTEs for 24*7 support. 

The typical shift timings are - 7am-4pm, 3pm-12 midnight, 11pm-8am, This ensures that there is a 1-hour overlap between each shift.
