The Meteor framework is a rising star. Other frameworks focus on separation of concerns or data binding or look and feel, but rarely put all the pieces together like Meteor does. Meteor is a full-stack isomorphic JavaScript framework for writing web and mobile apps that share code with the server and use MongoDB. It supports live updates and hot deploys, integrates with Cordova, AngularJS and other frameworks and tools, and has a unified package system for server and client packages. It also has a single tool that does everything and simplifies the everyday workflow: builds, cloud deployments, minification, managing target platforms and Meteor packages, and all the rest. In this session, you will learn about Meteor and see it in action.
Software testing is a vital process without which no software release can occur, it makes the software usable. Software testing offers opportunities constantly to be exposed with new development methods, new platform technologies, new product innovations.

It’s pretty fair to say that JavaScript is not a fad; it is by far
the most widespread programming language out there and also the most available runtime we have, ranging from toasters to the web, and even to the backend development through Node.js. Its probably also fair to say that we should really embrace it and start treating it like a first class citizen of our day to day work. In this talk, Einar will take you on a tour of how you can work with JavaScript with similar patterns you’re already used to from the rest of your server code. Writing tests or specifications that proves your code is also important, Einar will show how to get started with this and how you can achieve more testable JavaScript by applying patterns like MVVM (Model View ViewModel) using KnockoutJS

Sequence Like a Boss - BriForum 2015 DenverRyanWillDotcom
Presented By- Ryan Will and Drew Walz
In the continuation of the popular Sequencing for Success series, learn how to sequence like a boss. Just because an application doesn't work at first pass, it doesn't mean it can't be virtualized. In this session, discover how shims and symbolic links can improve application compatibility. Learn how to identify the files and folders that need them. Find out how to use the same tools to troubleshoot application errors once an application has been virtualized.
Session Takeaway: Because there are still many applications that have issues being virtualized, you will learn techniques that offer a second look at an application previously thought of as unable to be sequenced. Knock a new App-V project out of the park!

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
13. Missing things
Reflection API changed
Type details through GetTypeInfo() – extension
method
Emit namespace practically empty - security
14. XAML
Originally developed for Windows Vista and
exposed as WPF
Defines what you see
Layout is by default not flowing, as in HTML
Can observe changes (Active View)
25. TypeConverter
Converts data from XAML to CLR types and back
XAML will always give string
Can be defined on a DependencyProperty or on an object
with attributes pointing to the converter
26. Events
You still have events as before – buttons can
be clicked and raise an event
RoutedEvents – bubbles through the UI
27. Async
var data = DownloadData(...);
ProcessData(data);
STOP
DownloadData ProcessData
var future = DownloadDataAsync(...);
future.ContinueWith(data => ProcessData(data));
DownloadDataAsync ProcessData
29. Async – C# style
Marked with “async” modifier
Must return void or Task<T>
Use “await” operator to cooperatively yield
control – remember to mark with “async”
Feels just like good old synchronous code
30. Patterns & Practices
MVVM
Inspired by PresentationModel by Martin Fowler
Good for decoupling – promotes testability
Compositioning
Commands
Actions / Triggers / Behaviors
35. Tiles
Tap on tile to launch or switch to an app
Static default tile specified in app manifest
Two sizes:
Both sizes can have live updates
36. Live Tiles
Tiles updates using Templates provide Text-only image-only
pre-defined templates rich rendering options or combination
JPEG or PNG only, Optional “peek” Local or cloud
max size 150 KB animation updates
40. Process Lifetime Management
System manages application lifetime
One foreground full screen window
Apps are quickly suspended to preserve
battery life
41. Suspend
System resources focused on the app that
the user is interacting with in the foreground
Inactive apps have no impact on battery life
or responsiveness, they are suspended by
the OS
Enables instant switching between apps
42. Suspend details
Suspended apps are not scheduled by the NT Kernel
No CPU, Disk or Network consumed
All threads are suspended
Apps remain in memory
Kernel ensures apps are not suspended in critical sections that could
cause system wide deadlocks
Apps instantly resumed from suspend
when brought to foreground
43. Session State
SuspensionManager
SessionState
Property bag that is automatically serialized and saved when suspended
Reloads property bag from disk on activation
Does not reload state if app crashed
Only save and restore user session metadata
Tip: Don‟t wait till suspension to put data into SessionState
44. Session State : Best practices
User using app Launch
Save incrementally Restore session
App switch Resuming
Save navigation Do nothing
45. Termination
User explicitly closes the app: soft termination
System needs more memory
User switch occurs
System shutdown
Apps crash
Apps does not get notified when
they are getting terminated
46. Process State Transitions
User suspending
Running Suspended Low Memory Terminated
Launches
App resuming
App App
App
Splash
Code gets to run No code runs App not running
screen
47. Splash screen
System provides splash screen mechanism
Shown while Windows launches your app
Presented during activation
Developer provides color and image in app manifest
Apps need to present a window within 15 seconds of activation or the
app will be terminated
48. Background Audio Playback
Apps can play audio in the background
Developers must specify background audio in the app
manifest
Each audio stream is given a type (communication, media,
game)
Onle one audio stream type may play at a given time
49. Upload/Download in the background
Use the BackgroundTransfer API to upload or download
data over HTTP in the background
Initiate upload / download from the foreground and it can
continue though your app is suspended
50. Background tasks
Trigger / Condition based
System events
InternetAvailable
NetworkStateChange
OnlineIdConnectedStateChange
SmsReceived
TimeZoneChange
Background tasks for lock screen capable apps
Control Channel
Timer
Push Notifications
System events for lock screen-capable apps
UserPresent
UserAway
ControlChannelReset
SessionConnected
LockScreenApplicationAdded
LockScreenApplicationRemoved
51. Background tasks : resources
CPU resource quota Refresh period
Lock screen app
Non-lock screen app
52.
53. Windows Notification Service
Enables delivery of tile and toast notification over the
internet
Tile updates and notifications shown to the user even if
your app is not running
WNS handles communication with your app
Scales to millions of users
WNS is a free service for your app to use
54. Push Notification Overview
1. Request Channel URI
2. Register with your Cloud Service
3. Authenticate & Push Notification
55. Toast Notifications
Toast notifications deliver transient messages outside the context of the
app
Use toast notifications to get user‟s attention immediately
User is in control and can permanently turn off toast notifications from
your app
Allows quick navigation to a contextually relevant location in your app
Toast notifications are easy to invoke from your app or from the cloud
56. Toast Templates
Uses same template architecture as Live Tiles
Rich set of rendering options available
61. Share
Your app can share anything (text, images, binaries)
Automatically filters available applications to share to
Your app can be a share target – receive sharing from others
Add sharing target as a capability and you can receive share requests
64. Data
Isolated Storage is the key
http://metrostoragehelper.codeplex.com
Database
SQL Lite
http://timheuer.com/blog/archive/2012/05/20/using-sqlite-in-metro-style-app.aspx
65. Summarized
Windows RT is a huge leap, both in faith but also technically
Consistent API that feels mature from day one
Well architected solutions putting the user first
Makes us as developers focus on adding the business value

= “tombstoning” in Windows phone (read http://msdn.microsoft.com/en-us/library/ff817008(v=vs.92).aspx for the execution model in WP)This also visible with SysInternals Process Explorer (http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx) where you see the same “Suspended” in the CPU column. It was possible to “suspend” a process in Windows 7 with Process Explorer: this is now done by Windows itself for Metro Apps.NOTE: Process Explorer is fully aware of Metro Apps = “Immersive” has new blue color. See Options | Configure Colors | Immersive Process + see package in tooltipWhen you right-click | Resume on a Suspended Metro App, it gets back automatically Suspending immediately by Windows
The user can still decide to explicitly “close”/”end” an App by using ALT+F4 or the following touch gesture = “drag the top of the App and drag it down to the bottom of the screen”: in that case, the App gets the suspend notification after 5 secondsThe system is also allowed to “terminate” the apps.. [users can do it too via task manager or Process Explorer]There is no event fired during termination… you should save all your stuff by “suspending” or even better, along the user navigation in the AppDEMO: use Testlimit64 –d 1024 to consume as much memory (working set) as possible and see that first the Metro App working set are trimmed and then some Apps get terminated (download the tool from http://technet.microsoft.com/en-us/sysinternals/bb963901.aspx)Watch http://channel9.msdn.com/Events/TechEd/NorthAmerica/2011/WCL405 for Mark Russinovich talk about Windows memory management + demos of Testlimit
Splashscreen and background colors are set in the App manifest.It’s used by Windows to display the first screen before the App code starts to runSame during activation through Contracts
Splashscreen and background colors are set in the App manifest.It’s used by Windows to display the first screen before the App code starts to runSame during activation through Contracts
Ex: update cache on a regular basis such as for weekly TV programs
You can control when the background task runs, even after it is triggered, by adding a condition. Once triggered, a background task will not run until all of its conditions are met. The following conditions (represented by the SystemConditionType enumeration) can be used.For instance : InternetAvailable, InternetNotAvailable,SessionConnected, SessionDisconnected, UserNotPresent, UserPresentControl Channel : Background Tasks can keep a connection alive– ControlChannelTriggerTimer : Background tasks can run as frequently as every 15 minutesPush Notification : Background tasks respond to PushNotificationTrigger to receive raw push notifications
Resources for background tasks are throttled to make sure the background task is not consuming too much battery (both CPU time and network bandwidth)The throtting is tough for us (humans) to measure because it is CPU time.. When CPU is idle (e.g. making a network call) that does not count against you.. The way the metering happens is that you are allowed a quota within a period and as long as you do not exceed it, you are OK.. Once you exceed it, the system flat out ignores the triggers until the right amount of time has passed so you can’t assume that you’ll be timely called if you exceed your limit-- Network resource constraints are a function of the amount of energy used by the network interface, which is modeled as the amount of time the network is used to transfer bytes (for download or upload); it is not based on any throughput metrics. The throughput and energy usage of a network interface varies based on factors like link capacity, physical position of the device, or the current load on the WiFi network. WiFi networks typically have lower energy consumption per byte sent and received when compared to cellular mobile networks.
