For the software delivery process, the most important global metric is cycle time. This is the time between deciding that a feature needs to be implemented and having that feature released to users. As Mary Poppendieck asks, "How long would it take your organization to deploy a change that involves just one single line of code? Do you do this on a repeatable, reliable basis?"4 This metric is hard to measure because it covers many parts of the software delivery process—from analysis, through development, to release. However, it tells you more about your process than any other metric.

While continuous deployment implies continuous delivery the converse is not true. Continuous delivery is about putting the release schedule in the hands of the business, not in the hands of IT. Implementing continuous delivery means making sure your software is always production ready throughout its entire lifecycle – that any build could potentially be released to users at the touch of a button using a fully automated process in a matter of seconds or minutes. [...] In the world of continuous delivery, developers aren’t done with a feature when they hand some code over to testers, or when the feature is “QA passed”. They are done when it is working in production. That means no more testing or deployment phases, even within a sprint (if you’re using Scrum)...

ApiAxle is a proxy that sits on your network, in front of your API(s) and manages things that you shouldn't have to like rate limiting, authentication and caching. It's fast, open and easy to configure.

The Perl provided by your OS is ancient (yes, it is) and probably broken. We can fix that. Most of your programming problems are probably solved by a Perl module from CPAN, but if you don't know what that is, or how to install modules from it, you'll never use it. We can fix that as well. You've got production code that needs to keep running, but you still want to forge on with modern tools and approaches. We can help with that as well. This talk provides a rapid introduction to perlbrew, cpanminus, and local::lib.

Ever wanted to pin something to the side of a text? Ever needed a subtle sticky element to quietly hang around as you scroll down? jQuery.Pin is here to help! Pin any element to the top of a container. Easily disable it for smaller screen-sizes where there's no room for that kind of shenanigans.

Visualise your data in different ways. Each of them animated, fully customisable and look great, even on retina displays.

We all like to build software which is reliable, but every once in a while it seems like a good idea to demo something still in it's unreliable infancy. Google Chrome has a little known feature which can help. Record modes let you record every request Chrome makes. Playback mode serves requests out of that recorded cache just as if they were being loaded on the spot. It doesn't record where you click or what you open, just every request as it moves over the wire.

The first obstacle we reached when we were setting up our continuous delivery pipeline was figuring out which branch to continuously deliver. We changed our minds a few times before settling on a pipeline that would run all the code from the development branch. Except production, that is, which would deploy from master. This was always a bit confusing and didn't make a whole lot of sense. The idea with git flow is that master always represents production while develop represents the current state of development. The idea of continuous delivery, though, is to reduce the time between what master represents and what develop represents. In the ideal case, develop and master would converge. These worldviews clash quite spectacularly when tried to use in conjunction.
