Home · Microsoft/Detours Wiki
Detours is a library for intercepting binary functions on ARM, x86, x64, and IA64 machines. Detours is most commonly used to intercept Win32 APIs calls within an application, such as to add debugging instrumentation. Interception code is applied dynamically at runtime. Detours replaces the first few instructions of the target function with an unconditional jump to the user-provided detour function. Instructions from the target function are placed in a trampoline. The address of the trampoline is placed in a target pointer. The detour function can either replace the target function or extend its semantics by invoking the target function as a subroutine through the target pointer to the trampoline.

The Flame Graph - ACM Queue
Flame graphs can be generated from the output of many different software profilers, including profiles for different resources and event types. Starting with CPU profiling, this article describes how flame graphs work, then looks at the real-world problem that led to their creation.

Flame Graphs
Flame graphs are a visualization of profiled software, allowing the most frequent code-paths to be identified quickly and accurately. They can be generated using my open source programs on github.com/brendangregg/FlameGraph, which create interactive SVGs. See the Updates section for other implementations. Recently I've been helping with d3-flame-graph.

How are parameters sent in an HTTP POST request? - Stack Overflow | https://stackoverflow.com/
It /seems/ like the multi-value select boxes can be encoded by giving the variable name as 'fieldname[]'. Not positive, since I couldn't get it working quite right with Perl CGI.pm.

How can I send POST and GET data to a Perl CGI script via the command line? - Stack Overflow | https://stackoverflow.com/
<code class="language-perl">#! /usr/bin/perl
use warnings;
use strict;

use CGI qw/ :standard -debug /;

print "Content-type: text/plain\n\n",
map { $_ . " => " . param($_) . "\n" }
param;</code>

Also interesting:
To give a cgi script post data:
<code class="language-bash">$ echo -n 'a=b;c=d' | REQUEST_METHOD=POST CONTENT_LENGTH=999 perl index.cgi</code>

To give a cgi script get data:
<code class="language-bash">
$ perl index.cgi 'a=b;c=d'</code>


Of *course* that's how CGI works, but it's easy to forget that's how it works.
