This document provides an in-depth overview of Zone.js and how it works. It discusses:
- The event loop and how Zone.js intercepts asynchronous tasks like setTimeout and promises.
- How zones provide execution contexts and how Zone.js uses zones to observe and control code execution.
- How zones can be forked to create child zones and intercepted using hooks to monitor asynchronous tasks.
- How Zone.js monkey patches browser APIs and schedules tasks through the current zone rather than calling APIs directly.
New abstractions for concurrency make writing programs easier by moving away from threads and locks, but debugging such programs becomes harder. The call-stack, an essential tool in understanding why and how control flow reached a certain point in the program, loses meaning when inspected in traditional debuggers. Futures, actors or iteratees make code easier to write and reason about, and in this talk I'll show a simple solution to make them easier to debug. The tool I present integrates well with the Eclipse plugin for Scala, and shows how a "reactive debugger" might look like.

Nelson: Rigorous Deployment for a Functional WorldTimothy Perrett
Functional programming finds its roots in mathematics - the pursuit of purity and completeness. We functional programmers look to formalize system behaviors in an algebraic and total manner. Despite this, when it comes time to deploy ones beautiful monadic ivory towers to production, most organizations cast caution to the wind and use a myriad of bash scripts and sticky tape to get the job done. In this talk, the speaker will introduce you to Nelson, an open-source project from Verizon that looks to provide rigor to your large distributed system, whilst offering best-in-class security, runtime traffic shifting and a fully immutable approach to application lifecycle. Nelson itself is entirely composed of free algebras and coproducts, and the speaker will show not only how this has enabled development, but also how it provided a frame with which to reason about solutions to fundamental operational problems.

Why scala is not my ideal language and what I can do with thisRuslan Shevchenko
- The document discusses some of the author's criticisms of Scala, including its use of implicit parameters to configure runtime behavior, and lack of good support for asynchronous programming.
- The author proposes some workarounds, like annotating imports to avoid implicit conflicts, and patching the compiler to add more information to Future exceptions. However, the ideal solution would be language changes or improvements to asynchronous abstractions like Async.
- Overall, the author argues that Scala is not ideal for some use cases like asynchronous programming, but provides some workarounds people can use in the meantime. The best solutions require changes to the language and standard library.
This document discusses running Spark on the cloud, including the advantages, challenges, and how Qubole addresses them.

What is Augmented Reality Image Trackingpavan998932
Augmented Reality (AR) Image Tracking is a technology that enables AR applications to recognize and track images in the real world, overlaying digital content onto them. This enhances the user's interaction with their environment by providing additional information and interactive elements directly tied to physical images.
Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

Need for Speed: Removing speed bumps from your Symfony projects ⚡️Łukasz Chruściel
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.
4. WHAT IS ZONE.JS
• Library written by the team that is inspired by DART
• It provides a mechanism for encapsulating and intercepting
asynchronous activities in the browser
5. WHY ZONE.JS
• Useful for accessing data which persist across async operations.
• Useful for frameworks/applications to be able to schedule and
intercept async tasks
• Helps us detect theVM turns
• Useful for debugging, testing and profiling
6. ZONE
• A zone is an execution context that persists across asynchronous tasks.
• It allows us to control execution of the code within the zone.
7. ZONES.JS
• The library monkey patches all the async browser APIs.
• Redirects all the async operations trough a zone of interception.
• Creates a <root> zone.
• Provides a global Zone object used for zone management.
8. MONKEY PATCH
A monkey patch is a way for a program to extend or modify
supporting system software locally (affecting only the running instance
of the program).
( wikipedia )
13. CONTEXT PROPAGATION
• A zone keeps a reference to its parent zone.
• A given stack frame can be only associated with one zone.
• Data attached to the zone is shallow-immutable.
• Child zone inherit parent zone properties.
20. ZONE DELEGATE
• A delegate which handles the interception of the current zone
methods.
• This way a child zone can invoke a method on a parent zone.
• The wrap method delegates to intercept and the run method to
invoke.
21. TASKTYPES
• MicroTask - work which will execute as ASAP on empty stack frame.A microtask is
guaranteed to run before host environment performs rendering or I/O operations.
• MacroTask - Macro tasks are interleaved with rendering and I/O operations of the
host environment. (ie setTimeout, setInterval, etc..) Macro tasks are guaranteed to
run at least once or canceled. Macro tasks have an implied execution order.
• EventTask - Similar to macro tasks, but unlike macro tasks they may never run.
When an EventTask is run, it pre-empts whatever the next task is the macro task
queue. Event tasks do not create a queue.
33. PERFORMANCE OPTIMIZATION
• Asynchronous tasks that don't require UI updates or error handling
to be handled by Angular can be kicked off via "runOutsideAngular".
• If needed, these tasks can reenter the Angular zone via "run".
35. FAKEASYNC
• Instead of calling the browser, it saves all the calls into an array.
• It can then emulate the passage of time by going through that array
and invoking the stored functions.
