blogs
They don't
buy Perl
books
They don't
join Perl
Mongers

call
themselves
Perl
programmers
They are
programmers

“In the
kingdom of
the blind...”
“... the
one-eyed
man is king”
So much
misinformation
So many
outdated
practices
Web apps
Matt Wright's
CGI parser
Raw HTML in
strings
Advanced
programmers
use CGI.pm
HTML
generation
One bad
example
(not Perl specific)
Time zones
“There are
24 time
zones”
(actually there are 40)
“Time zones
all differ by
one hour”
(Venezuela: UTC-04:30
Iran: UTC+03:30
Nepal: UTC+05:45
and others)
“The UK uses
UTC”
(True – apart from the seven
months a year when we use British
Summer Time)
Perl
examples
“eq” is used
to assign a
string
You can't open
a file unless
you use
readdir() first
Stack
Overflow
Guess the
problem
“Perl thinks
my two
strings are
the same”
'foo' eq 'bar'
Ah yes, and you
are the first
person to have
noticed this bug
since 1987. Sure.
(Klortho #11943)
People lack
most basic
programming
skill
RTFM
A
suggestion
Perl
Community
Outreach
Team
Get out of
the echo
chamber
Take a
holiday in
the Kingdom
of the Blind
Help people
to improve
their Perl
(But do it
gently,
please)
Bonus side
effect
See how
other people
use Perl
See what
confuses
them
See what
docs can be
improved
Help the Perl
community to
improve
information
Everybody
wins
(Except,
perhaps,
your sanity)
Join me in
the Kingdom
of the Blind
Easy way to
make a
difference
See you on
LinkedIn
