The document discusses the importance of version control systems and bug tracking systems in software development, highlighting the evolution of version control from early systems to modern tools like Git and Mercurial. It emphasizes the professional practices that distinguish skilled programmers from amateurs, including automation, systematic testing, and debugging techniques. Additionally, various bug tracking systems such as Bugzilla, Jira, and Pivotal Tracker are briefly described, showcasing their features and functionalities.

run
it.

5. We
screwed
up
the
release,
can
we
roll
back
to
the
last
production
version?!!

6. ¡ Where
is
that
file?
¡ Where
is
that
bug?
¡ Who
last
changed
this
file?
¡ Who
made
that
change,
when
and
why?
¡ Has
the
code
changed
or
not?
¡ How
is
it
different?
¡ Can
you
put
your
fixes
into
my
files?
¡ Messy

8. Four
things
distinguish
professional
programmers
from
amateurs:
¡ Using
a
version
control
system
¡ Automating
repetitive
tasks
¡ Systematic
testing
¡ Using
debugging
aids
rather
than
print
statements

9. What
is
a
version
control
system?

13. So,
Bazaar
should
get
the
highest
priority
:P

14. branch,

and
few
more.

17. What
is
it?
-­‐
A
bug
tracking
system
is
a
software
application
that
is
designed
to
help
quality
assurance
and
programmers
keep
track
of
reported
software
bugs
in
their
work.
It
may
be
regarded
as
a
type
of
issue
tracking
system.
