Scott Meyers interview

I think a schism existed between the C++ community, which was still focused on language issues, and the other prominent development communities, which pretty much left the language alone. Java already had exceptions, but didn't have templates and had nothing like the STL. Yet the Java community focused on writing a whole bunch of libraries that everybody can assume will exist everywhere, libraries that will let you write applications really quickly. The end result is, we have templates in C++, but there's no way to write user interfaces or talk to databases. Java has no templates, but you can write user interfaces up the wazoo and you can talk to databases with no trouble at all.

contants

How about create a Class to hold all constant? How about static import? How about DON'T use it at all?

continuations

A more detailed discussion about this design approach, as far as I can tell is to put all session information to URL automatically.

Using stacktrace to know call hierarchy

Sometime it useful to know call hierarchy even if it is not exception case

global search sample

An nice article provide a complicate solution of global search - "Domain Searching Using Visitors". I think you can guess from the name, it is a solution which is look nice and damn flexible. However, this also very complicate and not everyone like to do that much upfront design first. Anyway, a nice reading

cool exception message

From a very good jpeg meta data extractor - http://drewnoakes.com/code/exif/ mention the solution at exception message

com.drew.metadata.MetadataException: Tag Image Width has not been set -- check using containsTag() first
        at com.drew.metadata.Directory.getInt(Unknown Source)

class are too big

Classes are to big ...

* When it is unclear what the exact responsibility of the class is. (when apparently little changes in requirements often require changes in the same set of classes, time after time)
* When it is difficult to write a unittest to test the behavior of the class. (very common for large classes that combine a lot of functionality)
* When the concept of the class no longer fits the size of your head. (working on the class becomes difficult, meaning you need to scroll a lot, skip between various parts of the code in order to understand the class. Differs a little from person to person.)

Kind Regards,
Sven
