MVVM and MVP are design patterns that improve upon the traditional MVC pattern by separating presentation logic from the view controller. MVVM moves presentation logic to a view model, reducing view controller complexity and improving testability. MVP uses a presenter layer to provide the view with data from the model, handling background tasks and keeping the view simple. Both patterns improve testability and maintainability over massive view controllers by dividing responsibilities between components.

Introduction to javascript templating using handlebars.jsMindfire Solutions
Handlebars.js is a JavaScript templating library. Web apps are using JavaScript to create dynamic interfaces now more than ever before, and that’s not a trend that will change any time soon. DOM manipulation is great for simpler JavaScript apps, but what do you do when you’re changing huge chunks of the document with each change of the view? That’s where JavaScript templating has a critical role to play.
In the mobile app development community a well-known issue is the problem of growing codebases.

Model View ViewModel (MVVM) is an architectural pattern that originated from Microsoft and provides a pattern for code-sharing across Windows Store and Windows Phone apps; however, you can take MVVM anywhere - including iOS and Android!
MVVM frameworks act as the glue that ties together the apps user interface and business logic and adds amazing features such as data binding and commands. There are several MVVM frameworks that allow you to share more code on iOS, Android, and Windows including Bind, MVVM Light, MvvmCross, and Xamarin.Forms ships with its own lightweight MVVM framework. Come learn what exactly the MVVM pattern is, and when to use it. We will go through the pros and cons of several architectural patterns, such as MVC and MVP, and compare them to MVVM. We will investigate several different MVVM frameworks from lightweight to heavier approaches. Walk away with the ability to leverage the MVVM framework for optimal code reuse in creating beautiful native mobile applications on every platform
The Model View ViewModel (MVVM) is an architectural pattern originated by Microsoft as a specialization of the Presentation Model (Martin Fowler). Similar to MVC, MVVM is suitable for client applications (Xaml-based, Xamarin, SPA, ...) because it facilitates a clear separation between the UI and the Business Logic. Examples with WPF, MvvmCross, AngularJs. It also contains solutions for common use cases.
Learn basics of Xcode, Objective-C syntax, Object allocation, message passing, category, core obj-c classes, how view-controllers work through some basic example apps.
MV* presentation frameworks in Javascript: en garde, pret, allez!Roberto Messora
HTML5 is the playing area, the strip, Javascript presentation frameworks are the fences and they are fierce and proud. In this presentation we will attend an interesting match between two of the emerging contenders in the MV* family: KnockoutJS and BackboneJS. We'll try to understand how they solve the same issues in modern web software development to better decide which one is suitable in our scenario.
A journey from MVC to VIPER is a try to leverage different application architectures (as well as some concepts on top of MVC) to build more clean and readable software in Cocoa. Most of the described techniques can be successfully used while dealing with legacy codebase.
Knockout is a JavaScript library that helps you to create responsive display(UI)
It is based on Model–view–viewmodel (MVVM) pattern
It provides a simple two-way data binding mechanism between your data model and UI
It was developed and is maintained as an open source project by Steve Sanderson, a Microsoft employee on July 5, 2010
Will your code blend? : Toronto Code Camp 2010 : Barry GervinBarry Gervin
XAML getting you down? Tired of the repetition of trial by error WPF or Silverlight development? If you’re not using Expression Blend to build your XAML, you’re doing it all wrong. Let’s take a look at the common pitfalls that new Silverlight developers fall into that make their code unblendable, and then leverage the patterns and techniques that allow us to unlock the virtues of Expression Blend. Testability, blendability, inner peace and maintainability are just 1 hour away
This is a talk I gave the at the AngleBrackets/DevIntersection conference in April of 2014 that covers the AngularJS JavaScript framework (one of my favorite frameworks out there!). In this talk I discussed the challenges with Single Page Applications (SPA) and how AngularJS helps solve those challenges with built-in support for two-way data binding, directives and filters, controllers and more. I also discuss the relationship of modules to controllers, factories and services, and more.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.

4. Cons
◦ Massive View Controller!
◦ Sometimes hard to test
◦ More “layers” are needed as app
grows
◦ Its an “Apple thing”
◦ Decrease code clarity
◦ There are better design
patterns
5. What better you say?
MVVM - Model View View Model
--iOS
MVP - Model View Presenter
--Android
6. MVVM
◦ View controllers are technically
distinct components, they
almost always go hand-in-hand
together, paired
◦ When is the last time that a
view could be paired with
different view controllers??
8. MVVM
◦ Most of the stuff in
ViewController is presentation
logic
◦ Things like transforming values
from the model into something
the view can present
10. MVVM
MVVM is an augmented version of
MVC where we formally connect
the view and controller, and move
presentation logic out of the
controller and into a new object.
11. MVVM
Why?
◦ Reduces the complexity of one’s
view controllers and makes
one’s presentation logic easier
to test
21. On top of that
◦ View can disappear and appear
at random time
◦ Do not forget about
saving/restoring of Views
◦ Attach a couple of background
tasks to that temporary Views
