O'Reilly.C.Sharp.3.0.Design.Patterns
Design patterns are among the major tools in the toolboxes of those who espouse the
generalist approach. If you look at samples from a broad spectrum of software solutions,
you will find that though the specifics may vary widely, there is often an
underlying structural similarity. (Searching a filesystem for a file with a particular
attribute is in some sense structurally similar to searching an annotated parse tree for
a symbol with a particular type.) Design patterns codify general solutions to common
problems.

C# in Depth (What_you need to master)
There are two kinds of pianists.
There are some pianists who play not because they enjoy it, but because their parents
force them to take lessons. Then there are those who play the piano because it
pleases them to create music. They don’t need to be forced; on the contrary, they
sometimes don’t know when to stop.
Of the latter kind, there are some who play the piano as a hobby. Then there are
those who play for a living. That requires a whole new level of dedication, skill, and talent.
They may have some degree of freedom about what genre of music they play and
the stylistic choices they make in playing it, but fundamentally those choices are
driven by the needs of the employer or the tastes of the audience.
Of the latter kind, there are some who do it primarily for the money. Then there
are those professionals who would want to play the piano in public even if they weren’t
being paid. They enjoy using their skills and talents to make music for others. That
they can have fun and get paid for it is so much the better.
Of the latter kind, there are some who are self-taught, who “play by ear,” who
might have great talent and ability but cannot communicate that intuitive understanding
to others except through the music itself. Then there are those who have formal
training in both theory and practice. They can explain what techniques the composer
used to achieve the intended emotional effect, and use that knowledge to shape their
interpretation of the piece.
Of the latter kind, there are some who have never looked inside their pianos. Then
there are those who are fascinated by the clever escapements that lift the damper felts
a fraction of a second before the hammers strike the strings. They own key levelers
and capstan wrenches. They take delight and pride in being able to understand the
mechanisms of an instrument that has five to ten thousand moving parts.
