Use Cases as a Requirements Management Technique
The body of knowledge surrounding use cases is large and can
be intimidating to the uninitiated. Let MKS help you
navigate through this abundance of information - learn about
the benefits of use cases and best practices for deploying
use cases as a requirements management technique.

Rebuilding When CPPFLAGS Changes
by John Graham-Cumming
=====================================
This article shows how to implement an important
"missing feature" of GNU Make: the ability to
rebuild targets when the commands for those targets change.
GNU Make rebuilds a target when it is "out of
date"; that is, it rebuilds when some of the
prerequisites are newer than the target itself. But what if
the target appears up to date, under the definition, but the
actual commands to build the target have changed.
For example, what happens if you do a non-debug build (by
typing make) and then run a debug build by typing make
DEBUG=1. Unless the build has been structured so that the
names of targets are dependent on whether the build is debug
or non-debug, nothing happens at all.
GNU Make has no way of detecting that some targets ought to
be rebuilt, because it doesn't take into account changing
the commands. If, for example DEBUG=1 causes the flags
passed to the compiler to change then the target ought to be
rebuilt.

Demystify parallel software builds
Builds are often “black boxes” with little visibility into
the causes of performance problems; it’s even harder with a
parallel build. Looking through log files is time-consuming
and next-to-impossible for a real build. This whitepaper
identifies common performance problems with parallel builds,
as well as techniques to identify performance bottlenecks.

What is source control?
by Eric Sink
===========================================
Sometimes we call it "version control".
Sometimes we call it "SCM", which stands for
either "software configuration management" or
"source code management". Sometimes we call it
"source control". I use all these terms
interchangeably and make no distinction between them (for
now anyway -- configuration management actually carries more
advanced connotations I'll discuss later).
By any of these names, source control is an important
practice for any software development team. The most basic
element in software development is our source code. A source
control tool offers a system for managing this source code.
There are many source control tools, and they are all
different. However, regardless of which tool you use, it is
likely that your source control tool provides some or all of
the following basic features:

What Kind of People Are We?
(Open Discussions in the forums)
===========================================
In a recent post in the Discussion forums these questions
were asked:
"It has to be said that it takes a certain kind of
person to be interested in CM. I have just read a comment
that "you have to have a passion for CM" - I
think this is true: but why is that? What are our common
traits? Is there one common psychological profile to which
we all conform? What kind of people are we?"
Read all the responses and let us hear your comments...
