I am trying to send a get or a post through a command-line argument. That is test the script in the command line before I test through a browser (the server has issues). I tried searching online, and I suppose I was probably using incorrect terminology because I got nothing. I know this is possible because I saw someone do it. I just don...
Hello I'm trying to build an IRC Bot which tells me in a private channel every commit-message which I want to know about.

I've read this article where the /^1?$|^(11+?)\1+$/ Perl regex is used to test if a number is prime or not. Process: s = '1' * your_number If s matchs the regex, then it's not prime. If it doesn't, it's prime. How would you translate that regex to Python's re module? ...
The number of values in a list can only be determined by iterating over its values, or converting it to an array. Assigning it to a scalar won't return the items count: my $n = ('a', 'b', 'c'); # $n = 'c' There's an "empty parentheses" idiom, that can be used to get the number of elements: my $n = () = ('a', 'b', 'c'); # $n = 3 I...
I have a Perl script that does various installation steps to set up a development box for our company. It runs various shell scripts, some of which crash due to lower than required ulimits (specifically, stack size -s in my case). Therefore, I'd like to set a ulimit that would apply to all scripts (children) started from within my main ...
Hello, I've looked at Net::Google, and 90% of the modules use AuthSub with a mandatory login/password. The right way for a web application to interact with Google applications on behalf of a customer is to use OAuth. That way, the authentication is done by Google, and the application does not know the user's password. This is supported b...
I want multi-line strings in java, so I seek a simple preprocessor to convert C-style multi-lines into single lines with a literal '\n'. Before: System.out.println("convert trailing backslashes\ this is on another line\ \ \ above are two blank lines\ But don't convert non-trailing backslashes, like: \"\t\" and \'\\\'"); After: ...

This is a continuation of my previous question: In Perl, how can I check for the existence of Socket options without generating warnings? If I run the following code I get the result I expect: #!/usr/bin/perl -w use strict; use diagnostics; use Socket qw(:all); my %opts; if ( defined( eval { SO_REUSEPORT } ) ) { $opts{'SO_REUSEP...

Newbie in rrdtool. I want to look at efforts required to establish a line of best fit on RRD charts so that we can detect long term trends - i.e. value is increasing over time. I have been recently using the Perl module Statistics::LineFit to help establish regression trends. Maybe there is a tool in RRD itself which makes it easier to ...

Things like "fileno", "dup" and "dup2" were working but then randomly inside some other environment, stopped working. It's hard to give details, mostly what I'm looking for is answers from experienced Windows programmers and how file descriptors ...
