Outstanding Objects (Developed Dirt Cheap)

Mark Leighton Fisher writes "Some readers might be interested in Outstanding Objects (Developed Dirt Cheap); or "Why Don't Developers Search the Literature?" It seems like I still see a lot of wheel reinvention going on, even with the wealth of code and information now available on the Net."

Simple explanation

It's because all us developers think our way is the better way :P

Not to mention how much CPU time each of those takes. For example, check out the "tinyurl.pl" example in CPAN. It uses:

use POE;
use POE::Component::IRC;
use LWP::UserAgent;
use HTTP::Response;
use HTTP::Request::Common;
use URI::Find;

Each of which probably use a good number of libraries themselves. Running perl -wc on the script takes .6 user CPU seconds alone - an approximation of how much CPU time it takes to start up (and by my measurement, a pretty accurate approximation).

Hell, check this out:

$ time perl -e "use POE"
0.23s real 0.21s user 0.01s system

Sick.

#!/usr/bin/env python

from qt import *
a=QApplication(sys.argv)
img=QLabel(None)
img .setPixmap(QPixmap("my_image.png"))
a.setMainWidg et(img)
img.show()
a.exec_loop()

You're welcome.
It would probably have been even shorter in Perl.

'Bloat' is not knowing the right tools for the task.
