Emulating Web Browsers
Here’s a tedious task for you to consider. When you log-in to your favorite website these days, you’re creating a JSON document and posting it to the service you’re logging into. Long gone are the days when you just posted simple form parameters from a whole post. I work on an emulation platform: one of…

Profiling Perl
Often we write perl scripts that loop a particular action. Not so often we write a perl script that is called in a loop by another tool. My script was attempting to do a http web login to emulate user traffic. However, I was not able to start more than 8 of these scripts a…

Crazy Perl Day
I’m surprised that this is the first time in Perl that I’ve bothered to use the posix character class [:alnum:]. Check this nuttiness out: ($::port_name, $::first_port, $::last_port) = $::port_range =~ /([[:alnum:]]+[^[:alnum:]])(\d+)-[[:alnum:]]+[^[:alnum:]](\d+)/; Yeah…it’s better with coffee.

Deduplication, continued.
OK, so what started out as a bash script grew into a rather finicky Perl script. I used a bunch of parallel hashes, judging things by combinations duplicate names, identical file sizes and actually scoring the path name and taking the highest score. I ended up no using the file hashes, because I decided that…

Modern Picture Management?
I like to run a thumbnailer across most of my photos so I have little copies to send around, and I mod them so that they look distinctly different from the full resolution source files. I like to use gwenview to flip and rotate them. Gwenview can export to FB and email so that makes…
