My most successful open source project.

A common tactic when pentesting web applications is to brute-force files and directories. I'm not a fan of flooding servers with lots of traffic, so I wrote meg to look for one thing in lots of places instead of lots of things in one place.
I wrote comb because I often found myself writing pretty much the same nested loops in bash to output every permutation of the lines in two files. Having a dedicated tool speeds things up a lot.
In the process of writing meg I found myself needing to send requests that had malformed escape sequences and other unusual payloads that Go's HTTP library did not support. I wrote the rawhttp package to give me more fine-grained control over HTTP request.
Link headers are often used in HTTP APIs for Pagination, and parsing them turns out to not be all that easy. I wrote the linkheader Go package to do the heavy lifting.
Wake On LAN is a way to make computers power on by sending them a 'Magic' packet over a local network. phpwol is a PHP library to do just that.
It's a fairly common pattern to use a symlink to point to the current version of a codebase. Sometimes it's neccesary to restart processes or clear caches when the version of a codebase changes, so I wrote symwatch to poll a symlink for changes and run a command when they happen.
A while ago I had a need to figure out which xterm color code was the closest to a 24bit color, so I wrote a Go palette and command line tool called xtermcolor to do it for me.
globwatch is a Go package I wrote to watch a glob pattern (e.g. *.log) and emit 'events' when new files match the pattern, files are deleted, or truncated.
Several years ago I found myself writing quite a few command line tools in PHP, and I noticed I was writing very similar code in every tool to process arguments, output things as tables etc. I wrote phargs as a little toolkit to make those kinds of tasks easier.
flatclass is a debugging tool I wrote to make it easier to read and debug PHP classes with deep inheritance trees. It uses reflection to 'flatten' an inheritance tree by recursively copying parent methods into the target class.
My first security related talk, and the first ever BSides Leeds was a fantastic venue for it. I talk about (mostly) passive ways to gather information on a target for pentesting or taking part in bug bounty programs; like Google Dorking, grepping through GitHub repos, decompiling Android applications, and using Archive.org's Wayback Machine.
I also introduce a tool I wrote for 'breadth-first' scanning, and some examples of the kinds of things I've found with it.
A compliation of tips and tricks I've gathered across more than a decade of reading source code.
There's nothing particularly groundbreaking here, but I really wanted to collect all of the things that I think make it easier to read code into one place.
Live-coding a simple language VM on stage. What could possibly Go wrong?
Things like the JVM used to just seem like magic black boxes to me, so I decided to learn how they work. Once I'd realised how simple the core concepts are I couldn't help myself but to share.
