Perl - Using HTTP::Lite
I recently had to use the HTTP::Lite perl module and thought I would share an example of how to use it. HTTP::Lite was is available on www.cpan.org; its very lightweight and has no dependancies other than Socket & Fcntl which included with almost all Perl implementations by default. Based on the examples by the HTTP::Lite author Roy Hooper rhooper@thetoybox.org [perl] #!perl use HTTP::Lite; # # Get and print out the headers and body of the Google homepage # $http = new HTTP::Lite; $req = $http->request("http://www.google.co.uk/") or die "Unable to get document: $!"; # Print the reconstructed status line print $http->protocol() . " " . $req . " " . $http->status_message() . ""; # Get the Headers & Body @headers = $http->headers_array(); $body = $http->body(); # Display each Header foreach $header (@headers) { print $header . "\n"; } print "\n\n"; # Display the Body print $body . "\n"; # # Execute a Google Search using the POST method # $http = new HTTP::Lite; # Post variables %vars = ( "hl" => "en", "q" => "cpan", "btnG" => "Search", "meta" => "" ); $http->prepare_post(%vars); $req = $http->request("http://www.google.co.uk/search") or die "Unable to get document: $!"; # Print the reconstructed status line print $http->protocol() . " " . $req . " " . $http->status_message() . ""; # Get the Headers & Body @headers = $http->headers_array(); $body = $http->body(); # Display each Header foreach $header (@headers) { print $header . "\n"; } print "\n\n"; # Display the Body print $body . "\n"; [/perl] Google doesnt support queries by POST methods anymore, so the response to the second request here will be a "501 Not Implemented".

Loop Engineering: The Loop Was Never the Hard Part
Stop prompting, start looping — but the loop is the easy 20%. After a year shipping agentic loops (and a $500 runaway), here's the part the hype keeps getting backwards: the done-check and the verifier.
Two Papers That Puncture the Hype
One paper shows frontier models degrade as context grows — even on trivial tasks. The other shows reasoning models hit a wall and think less as problems get harder. Read carefully, both point at the same engineering response.
The 30 Principles for Agentic Engineering — Part 5: Calibration and Reality
Principles 26–30. The calibration layer that catches what the rest of the framework would miss: a PR-noise budget, independent verification, model-swap regression discipline, the 15-tool-call rule, and protecting junior development.
