Please note, we are also discussing this topic here:
Forum Trivial Pursuit - New Computer Science and Mathematics Trivia for UNIX.com
... and will be documenting our database structure if we must reverse engineer the JSON to create our own version of the DB.
Again, we are not “complaining”¯ in the least and understand the good folks at PixelTail are very busy and there is currently over 3000 questions in the trivia DB queue waiting to be validated; we just want to insure that if we create our own “computer science”¯ related DB (so we can validate faster), that we can eventually dump this DB and merge it with the Open Trivial DB.
We want all our work in the future to be compatible with the Open Trivial DB.
Current stats at Open Trivia DB:
Basically, there has been no movement in the number of verified questions since we began this discussion thread and our two "test question" have not been verified.
In the "not so distant future" I will take the time to reverse engineer the DB and post the results here.
If anyone else has the time to do it (reverse engineer the Open Trivial DB from the API JSON), before I get around to it, please do!
Hello guys!

Hello all!
I used to use expr for doing simple mathematics, but has a main advantage and a main disadvantage:
The advantage is that it can take variables for numbers
(e.g.{1}: echo "Give me first"
read lol
echo "Give other"
read lil
sum=`expr $lol + $lil`
echo "The sum of $lol and $lil =... (5 Replies)

browser::open
Browser::Open(3) User Contributed Perl Documentation Browser::Open(3)NAME
Browser::Open - open a browser in a given URL
VERSION
version 0.03
SYNOPSIS
use Browser::Open qw( open_browser );
### Try commands specific to the current Operating System
my $ok = open_browser($url);
# ! defined($ok): no recognized command found
# $ok == 0: command found and executed
# $ok != 0: command found, error while executing
### Try all known commands
my $ok = open_browser($url, 1);
DESCRIPTION
The functions optionaly exported by this module allows you to open URLs in the user browser.
A set of known commands per OS-name is tested for presence, and the first one found is executed. With an optional parameter, all known
commands are checked.
The "open_browser" uses the "system()" function to execute the command. If you want more control, you can get the command with the
"open_browser_cmd" or "open_browser_cmd_all" functions and then use whatever method you want to execute it.
API
All functions are not exported by default. You must ask for them explicitly.
open_browser
my $ok = open_browser($url, $all);
Find an appropriate command and executes it with your $url. If $all is false, the default, only commands that match the current OS will be
tested. If true, all known commands will be tested.
If no command was found, returns "undef".
If a command is found, returns the exit code of the execution attempt, 0 for success. See the "system()" for more information about this
exit code.
If no $url is given, an exception will be thrown: "Missing required parameter $url".
open_browser_cmd
my $cmd = open_browser_cmd();
Returns the best command found to open a URL on your system.
If no command was found, returns "undef".
open_browser_cmd_all
my $cmd = open_browser_cmd_all();
Returns the first command found to open a URL.
If no command was found, returns "undef".
