Graphs are one of the best abstractions we have for modeling connectedness. Graph databases, in turn, are one of the best tools at our disposal for modeling, storing and querying complex, densely-connected data. Today, graphs and graph databases are helping solve some of the world's most challenging data problems, in domains as diverse as search, social networking, recommendations, datacenter management, logistics, entitlements and authorization, route finding, network monitoring, and fraud analysis.
This month we'll be taking a peek inside the graphista's toolbox. We'll look at some common graph data structures, and the graph database queries that unleash the insights buried inside them. We'll survey some of the tools and techniques you can use to graph your world, experiment with graph data, and apply it in your own applications. And we'll draw lots of circles and lines. We might even colour some of them in.
Ian works on research and development for future versions of the Neo4j graph database. Harbouring a long-held interest in connected data, he was for many years one of the foremost proponents of REST architectures, before turning his focus from the Web's global graph to the realm of graph databases. As Neo Technology’s Director of Customer Success, he has worked extensively with customers to design and develop graph database solutions. He is a coauthor of 'Graph Databases' and 'REST in Practice' (O'Reilly), and a contributor to 'REST: From Research to Practice' (Springer) and 'Service Design Patterns' (Addison-Wesley).

Liam is back and this time, its to discuss EventStore
Ever thought about using event sourcing to enable CQRS (Command QueryResponsibility Segregation), or did you just want an easy manner of creating an audit trail or a notification system?
EventStore (http://geteventstore.com/) is an open source DSD (DomainSpecific Database) engine designed just for that, driven forward by GregYoung (https://twitter.com/gregyoung and http://codebetter.com/gregyoung/).
This is for people who want to find out what EventStore provides, the installation options, how you get data in and out, and why it's a fantastic solution if you have the right sort of problem.

For those of you who haven't heard of it, Nancy is a lightweight framework for building HTTP based services and it's a a great alternative to ASP.NET MVC and WebAPI. In this talk I'll start by showing you the basics of setting up a new Nancy application, introducing all you will need to know to create your first CRUD application. This will include:
Handling routes and HTTP Verbs
Model binding and validation
The basics of testing your application
I'll also speak briefly about why I feel its a better option than ASP.NET and go onto show you how easy it is to integrate into an existing MVC application.
I'll be doing some live coding so you're more than welcome to bring along your laptop and join in, but its not essential. If you do you'll need a copy of Visual Studio.
Mathew McLoughlin is a developer with a love of all things .NET. He has a passion for all new technologies in particular Nancy. He believes in using the right tool for the right job and not everything needs to come from the Microsoft stack.
In the last view years he has worked mainly on a large scale web application with a strong focus on real time data.

The new Async features come along with the very useful WhenAll and WhenAny methods to execute sets of tasks.
We will delve into how these work, the effect of exceptions within any individual task and cancellation. This leads to the creation of common patterns such as Redundancy, Interleaving, Throttling and Early Bailout.
Given time we'll also get to peek at progress reporting, something that provides the feedback to add further sophistication to these common patterns.
Expect overviews of the patterns, followed by lots of code samples so get the latest of Visual Studio 2012 installed ready for action.

There's a whole lot of hype around databases that have one thing in common: they don't use SQL for querying. The NoSQL monicker covers a whole range of different types of data stores, each with their own advantages and disadvantages.In this talk, Matthew Revell will look at the major NoSQL categories, as well as when and why you'd use them.
Matthew is Community Manager for Europe at Basho, the people behind the Riak distributed database. He has been knocking around the open source world for thirteen years and believes the most important part of a G&T is good tonic water.

Metaphorically speaking, the world is shrinking every day. Ironically this means that it is getting less acceptable to brush aside cultural differences and pretend that all cultures are essentially English but with different words. Appreciating globalization is about achieving humility, understanding that the world is a lot bigger than most developers give it credit for. Most developers understand that different cultures use different date formats, number formats and currencies. However, how many developers do not know that postal code formats, phone number formats, address formats and person name formats also differ. Not to mention the issues of localizing for gender-based languages or languages with less simplistic plural forms. What about ordinal subscripts, ordinal words, alphabet character sets ? The intention of this session is to open eyes, provide globalization enlightenment and with luck it will scare the living bejeezus out of you enough to make you question every line of code you write.

So you have decided to break up that monolithic application into services, after all it worked for Amazon, right? Perhaps you want to embrace the DevOps model, perhaps you want to scale your development. But just how do all those services talk to each other, and how do you build a UI on top of them?
In this session we will look at the event driven architecture approach and give you an understanding of how we use messaging to communicate, just what we are communicating about, and how to build a composite UI.

If you believe the blog and twittersphere we're all writing sleek well designed, SOLID, test covered, behaviour driven, pluggable, perfomant, immutable, asynchronous node.js in sharded erlang on our ubuntu phones. If you aren't then apparently you're some form of knuckle dragging neanderthal. But guess what? Codebases exist well after the high paid consultants abandon their half baked designs. The majority of codebases are ugly, broken and damn scary to work with and the majority of software development is carried out on those codebases!
In this session you'll be joining Johnno Nolan in dissecting and discussing legacy code and with any luck, making some of it better too.
Laptops preferred. Language agnostic. Opinions required from developers of all skill levels.
NOTE:- Given the nature of this event, The Wrekin Housing Trust have very kindly agreed to allow us to hold this event in their big meeting room at their offices in Telford. Furthermore, to get the most from this session, it will start at 18:30 and run until 21:30.
Don't forget: different venue, different time!
Contact Martin if you've any questions regarding this event
