July 29 - A Month of Magic

This month, we have two magical talks for you.

Collaborative Filtering - the magic of recommendations (Weiming Chen, @mingstar)
Ever wonder how Amazon generate its book recommendations? Do you want to do the same for your site? Introduce Collaborative Filtering (CF), one of the commonly used technique deployed by recommender systems. CF helps you to dig out the values of server logs, transaction history, and increase user engagement and loyalty. In this talk, sample C# code will be presented to illustrate the guts of CF.

Weiming works on data-driven products in Fairfax Media that serve millions of users, his expertise is on data analytics, recommender systems, Hadoop, and MapReduce

Aaron presents something magical* (Aaron Powell, @slace)
Have you ever implemented elementary arithmetic in code? What happens at a code level when you add two numbers? Come for a journey on some of the most pointless software there is and learn the magic of numbers!

* HINT: think surreal numbers and JS... And yes, he asked for that title :-)

June 24 - BIG data

Big data is all the rage.. there's a lot of competing options which cover off different areas of the space; from AWS Redshift at the SQL end, to Mongo to Hadoop and Lucene at the other. So.. you guessed it! This month is BIG DATA theme night. We'll have talks on the technology and real world implementation & code.

Add a Billion Row Data Warehouse to your App.. with Redshift, sql and duct tape!

Started to hit the point where your transactional database is not the right place for running reporting queries and experimental data science? Keen to chuck in more data from web logs, CRMs, facebook, etc so you can start learning more about your users? James Crisp (@jtcrisp) will show you an easy way to do it with AWS Redshift, mapping SQL and some simple scripting duct tape.

The Power of the Elephant in the Microsoft Cloud

Jibin Johnson and Simon Waight from the Azure User Group and Kloud Solutions will walk us through the cloud-based Big Data pipeline from Microsoft looking at how Azure’s HDInsights and Office 365 Power BI can deliver insights out of raw data.

Jibin Johnson is a cloud development consultant who has worked on some the largest on-premise and cloud-based solutions in Australia. Simon Waight (@simonwaight) is a cloud architect with almost 20 years’ experience in delivering online services for a range market verticals.

Remember to RSVP too please to help us get the right amount of food and beer!

May 27th, 2014 - .NET vNext and Edge.Js

There were some significant announcements made at this month's TechEd North America, especially those related to .NET vNext, Roslyn and the way we build applications. The changes will impact each and every .NET developer in the future and the sooner you understand what's happening, the sooner you can prepare yourself for the future and adjust the direction of the projects you're currently working on.

.NET vNext - Aaron Powell (@slace)

14 years ago the .NET framework was released at version 1.0 and since then a lot has changed.

Single monolithic frameworks are no longer the name of the game. The rise of NuGet has seen our .NET projects get more modular, being comprised of small specialised dependencies that do one job and do it very well.

Other platforms have also risen up, with Ruby and Node.js we have small, light-weight application being built, and being built in a way that we can load multiple versions of the runtime at the same time.

And lastly there's a new compiler in town, Roslyn, a C# & VB.NET compiler-as-a-service that now underpins everything .NET at Microsoft.

With all these changes it's time for the .NET framework to evolve with it.

Edge.JS - Richard Banks (@rbanks54)

Node and .NET living together? Sacrilege! Horror! Awesomeness! Sweeeet! Your reaction may vary, but it's possible, it's here and it's really kinda interesting and potentially useful.

So let's take a short trip into the trippy land of round tripping between Node and .NET and see where and how this rabbit hold might lead and if there truly is a pot of gold at the end of these mixed metaphors I've been abusing.

RSVP if you're coming and we'll see you soon!

All the new and shiny from \\BUILD 2014

So \\BUILD for 2014 has been and gone, but in it's wake is a whole lot of new toys for us to get to know and make the most of.  Thing is, so much new means we're going to need volunteers to make this month happen and do lightning talks on some of the various subjects.

So, if you'd like to have a go talking through one of the announcements at \\BUILD and why you think it's cool and sexy, and why we should care then drop either James or Richard a line and let them know you want to talk, or just drop a comment on the Facebook page.
By the way, don't worry if you've never talked in public before - you're among friends and we'd love you to have a go. Plus it's OK if you don't really know much about your chosen topic either - you only need to cover 10 minutes or so and we probably don't know much about it either :-)

P.S. If you want some inspiration then here's some, but not all, of the things covered at \\BUILD:

  • Windows 8.1 Update 1
  • Universal Apps
  • Touch version of Office
  • Cortana (Windows Phone) - if you have one, bring it!
  • IE11 Enterprise Mode (for those of us wanting to kill off IE8!)
  • IE11 Dev tools [TAKEN]
  • Windows and The Internet of Things
  • Azure - Puppet, Chef and Powershell [TAKEN POWERSHELL]
  • VS Browser Link updates
  • ASP.NET MVC 5.1 and Web API 2.1 new bits
  • Identity 2.0 new bits [TAKEN]
  • TypeScript 1.0
  • .NET Native Compilation
  • Node.js projects in Visual Studio
  • Azure Webjobs
  • Xamarin and Microsoft love in [TAKEN: talk on Xamarin & Native interop see below]
  • .NET Foundation (Open Source .NET projects)
  • Roslyn
  • The new Azure portal & VSO
  • Application Insights
  • Kinect for Windows v2
  • DirectX 12 [TAKEN]
...or you could choose something else completely!

It would be great for us to get through as many of these as we possibly can on the night, so either volunteer or just come along and be part of the fun. RSVP by grabbing a free ticket from the event page (or just click in the event box on the right of the page) and we'll see you there.

Abstracts & talks so far....

Jessica Brazelton - Binding Java & Objective-C Libraries in Xamarin Studio
Most 3rd party libraries for mobile applications are designed to work with the native programming language for that application. This presentation will give an overview of how to bind those libraries so that you can use them in Xamarin Studio.

Jason Stangroome - Exciting new powershell

Aaron Powell - updates to the IE11 dev tools

Adam Korczynski - Identity 2

Luke Drumm - Direct X 12.

March Madness with some Crazy Cecil and Immutable Databases

After a little speaker wrangling we have the following talks lined up for this month...

The Dark Art of IL Rewriting for Fun and Profit - Philip Laureano (@philiplaureano)

In this session, we'll talk about how to use Mono.Cecil to modify .NET assemblies to do some useful (and unusual) things, such as:

  • Intercepting third-party method calls, including calls to libraries that you don't own (like the System.* namespace in the BCL) for mocking purposes
  • Swapping/replacing method bodies at runtime
  • Intercepting property getters and setters for caching purposes
  • Making all public methods virtual for use with your favourite ORM
  • Unsigning "signed" assemblies

We'll also talk about why you would want to do something like this, as well as introduce a IL-rewriting library named Fody, which you can use to do all of this stuff for you.

Killing the U in CRUD with Immutable Databases - Richard Banks (@rbanks54)

In an act of practicing what he preaches, Richard follows that thinking that the best way to learn about something being to do a talk on it. Time to see if this actually works.

The subject? Immutable Databases. What they're all about, the problems they try and solve and why you might actually want to use an approach to data storage that most people would think is completely and utterly bonkers. Probably the same people that said NoSQL would never take off.

So step out of your comfort zone and spend a Tuesday night hanging out with other like minded nerds and geeks, and see what you all the fuss is about.

Grab a ticket so we know you're coming, tell your friends (if you have any) and we'll see you on the night!
