The document discusses human interface guidelines and memory management principles for mobile applications. It provides recommendations for designing intuitive user experiences, including defining interactions, navigation, and visual elements like images and icons. It also covers important memory management topics like retain counts, shallow vs deep copying of collections, retain cycles, and using weak references to avoid memory issues.
The document discusses memory management techniques in Objective-C, including manual reference counting (MRR) and automatic reference counting (ARC). It covers how MRR works by incrementing and decrementing retain counts, and issues like memory leaks and dangling pointers that can occur if the counts are not balanced. ARC is introduced as a way to automate MRR by having the compiler insert the appropriate memory management calls. The document also discusses retain cycles, where strong references between objects prevent deallocation, and ways to prevent leaks like breaking retains explicitly.
Memory management in Objective-C is semi-automatic, requiring the programmer to allocate memory for objects using alloc or convenience constructors, but not requiring de-allocation. Every object has a reference counter that tracks the number of references retaining it; sending retain increments the counter, while release decrements it. When the reference counter reaches zero, the object is automatically de-allocated. The programmer must follow rules to balance allocations, retains and releases. Autorelease pools are used to defer releasing of objects until the pool is drained. Newer versions of Xcode use Automatic Reference Counting (ARC) to automate more of memory management.
Objective-C uses reference counting to manage memory, where each object has a reference count that is incremented when retained and decremented when released. Objects are deallocated automatically when their reference count reaches 0. Autorelease pools are used to delay the release of autoreleased objects until the end of the current scope. Memory management conventions and properties help ensure objects are properly retained and released to avoid leaks or crashes.
The slides explain Memory management in objective C with reference to Cocoa and IOS. Difference between ARC and manual memory management is explained. Go through the presentation to understand how memory management is done in objective C.
Advanced Memory Management on iOS and Android - Mark Probst and Rodrigo KumperaXamarin
The document discusses advanced memory management techniques on mobile platforms. It begins with an overview of how garbage collectors work by computing which objects are reachable and freeing unreachable objects. It then discusses specific techniques for iOS and Android like generational garbage collection, stop-the-world pauses, and avoiding indirect cycles through weak references. Finally, it provides examples of common memory issues and how to address them, such as ensuring unmanaged resources are properly disposed.
The document discusses Swift memory management and ARC. It explains that Swift uses reference counting, where objects remain in memory as long as their retain count is above zero. With ARC, memory management calls like retain and release are inserted by the compiler based on strong, weak and unowned references. While reference counting works automatically with ARC, some issues like retain cycles cannot be detected as they can with tracing garbage collectors used in other languages.

Memory management in Swift is fairly abstracted away from you as a developer and it’s easy to build iOS apps without an understanding of it… until something goes wrong. This can result in unexpected behavior, unclear error messages, lost data and crashes. Even a basic understanding of memory management can go a long way, making it easy to prevent these issues in the first place, understand what when wrong when they do occur and know how to fix them.
This document discusses memory management techniques in Objective-C, including manual retain release (MRR), automatic reference counting (ARC), and how to avoid memory leaks and dangling pointers. It explains the rules of ARC and concepts like strong and weak references. Strong references can cause memory leaks if a strong reference cycle occurs between two objects. To fix this, one of the references in the cycle should be changed to a weak reference so that object does not have an owner and can be deallocated.
This document discusses hooks, events, and the event dispatcher in Drupal 8. It provides an overview of hooks and why they were replaced by events, which allow for more object-oriented and loosely coupled code. It describes how to create event subscribers by implementing the EventSubscriberInterface and defining subscriber methods. It also covers how to dispatch events by extending the base Event class and calling the dispatch method on the event dispatcher service.
We now know that we have an Event system in place in Drupal 8 which has been imported from Symfony, the Symfony Event Dispatcher Component. The Event system will likely replace the traditional hook system altogether in coming drupal versions. This talk will try to throw some light on how to create, trigger, subscribe and listen to events in drupal 8.
This session will mainly elustrate:
What are Events. Why do we need to trigger events?
What all do we need Events for and where we are still stuck with hooks.
Events in Drupal 8
Symfony Event Dispatcher component
When to fire an event.
When to expose your hook in Drupal 8? Never.

Beginning icloud development - Cesare Rocchi - WhyMCAWhymca
The document discusses beginning development with iCloud. It provides an overview of iCloud and how it works, outlines alternatives to iCloud like Dropbox and Parse, and dives into some technical details of implementing iCloud syncing for documents and custom data types using features like UIDocument, NSMetadataQuery, NSUbiquitousKeyValueStore, and conflict resolution. Tips are provided around testing, file handling best practices, and deciding whether to use iCloud or alternative services.
The document discusses the Swift runtime and its relationship to the Objective-C runtime. It notes that Swift can interoperate with Objective-C on Apple platforms thanks to the shared Objective-C runtime, but not on other platforms like Linux which use a custom runtime. It also discusses object-oriented programming concepts like messaging and monkey patching in Objective-C.
Drupal 8, Where Did the Code Go? From Info Hook to PluginAcquia
Looking at core and contrib modules for Drupal 8, you may be wondering "where did the code go?". Drupal 8 has removed many of the "info" hooks that were found in your module file and converted them to plugins.
In this webinar, we’ll discuss how plugins work and how to upgrade your module to Drupal 8 if it used one of the hooks that's been converted to a plugin.
Topics covered will include:
-Essentials of implementing your own plugin if your module previously used an “info” hook
-An explanation of plugin terminology and different ways plugins can be discovered
-Examples of code from Drupal 7 and where the very similar code lives in Drupal 8
-How to avoid implementing hooks by mistake when writing a function in your modules

+ = ❤️ (Firebase for Apple Developers) at Swift LeedsPeter Friese
In this talk, I am going to walk you through the building blocks for creating modern applications on Apple’s platforms using SwiftUI and Firebase.
We will cover the following topics:
- Setting up an architecture for data-driven applications
- What’s new in SwiftUI’s application life cycle
- Syncing data in realtime across multiple devices with Cloud Firestore
- Mapping Firestore documents in a type-safe way using the Codable protocol
- Using Combine to fetch data from remote APIs and Firebase
- How async/await (new in Swift 5.5) will affect the way we write asynchronous code (plus some surprises in Firebase's code base)
Firebase is always evolving, so I will also talk about how we’re making use of Apple’s latest technologies in our own code base, for example
- Combine
- async/await
- SwiftUI view modifiers
No matter if you’re a seasoned Firebase user or just wondering what it is all about, you should leave this session with a deeper understanding of what Firebase it and how you can use it your apps on Apple’s platforms.
JavaScript language plays a very important role in Web 2.0 application development. JavaScript has its own characteristics different than object-oriented languages and it's not easy for developers to understand.
This presentation covers major advanced topics in JavaScript languages, including prototype chain, identifier resolving, "this" keyword, "new" operator, execution context and scope chain and closure. Besides that, it also covers best practices when using JavaScript.

Jilles has experience using Docker at Inbot to improve the separation between development and operations work. Some key points:
- Docker helps address the problem of standardized software packaging and runtime configuration, separating provisioning responsibilities for developers and operators.
- At Inbot, Docker was adopted in 2014 and helped eliminate Puppet and move infrastructure to AWS. It simplified software dependencies and improved deployment speed.
- Dockerfiles provide a clear documentation of what is needed to run software, replacing complex configuration scripts and reducing operator workload.
Groovy there's a docker in my application pipelineKris Buytaert
This document discusses using containers and pipelines to automate the deployment of a Dashing dashboard application. It describes building containers for different components like Ruby, then using those containers to build and test the Dashing application. Jenkins pipelines are used to automate the build, test, and deployment process. Key challenges addressed include managing dependencies, running tests across environments, and reproducing builds. The document advocates defining pipelines as code using the Jenkins Job DSL plugin to centrally manage and version pipeline jobs.
OSMC 2017 | Groovy There is a Docker in my Dashing Pipeline by Kris Buytaert NETWAYS
Dashing or rather Smashing is an awesome Monitoring Dashboard, but it’s a pita to deploy. This talk will document the efforts we went trough to make the deployment of both dashing and the dashboards fully automated. It also will show how we test these dashboards using docker and how we build these pipelines with the JenkinsDSL.
This document discusses good and bad slide design for PowerPoint presentations. It begins by providing examples of "bad slides" including putting too much text on slides, using meaningless animations, including endless bullet points, having bad color design and images, and including invisible text. It then discusses principles of good slide design such as including one main idea per slide, using short phrases and less than 5 bullet points, and ensuring slides share some identical features. The document emphasizes designing slides to effectively communicate your message to the audience.
This document provides an introduction to reverse engineering and discusses cracking Windows applications. It begins with a disclaimer that reverse engineering copyrighted material is illegal. It then defines reverse engineering as analyzing a system to understand its structure and function in order to modify or reimplement parts of it. The document discusses reasons for learning reverse engineering like malware analysis, bug fixing, and customizations. It outlines some of the history of reverse engineering in software development. The remainder of the document focuses on tools and techniques for reverse engineering like PE identification, decompilers, disassemblers, debuggers, patching applications in OllyDbg, and analyzing key generation and phishing techniques.
Pipeline as code for your infrastructure as CodeKris Buytaert
This document discusses infrastructure as code (IAC) and continuous delivery pipelines. It introduces Puppet as an open-source configuration management tool for defining infrastructure as code. It emphasizes treating infrastructure configuration like code by versioning it, testing it, and promoting changes through environments like development, test, and production. The document also discusses using Jenkins for continuous integration to test application and infrastructure code changes and building automated pipelines for packaging and deploying changes.
The document discusses the history and principles of object-oriented programming (OOP). It notes that while OOP concepts like objects communicating by passing messages have existed since the 1970s, OOP languages like C++ and Java that supported these techniques did not emerge until the 1990s.

14. Copying Collections
COPYING
DEEP VS SHALLOW
There are two kinds of object copying: shallow copies and deep copies. The normal copy is a shallow copy
that produces a new collection that shares ownership of the objects with the original. Deep copies create
new objects from the originals and add those to the new collection. This difference is illustrated by Figure

15. RETAIN / RELEASE
Application memory management is the process of allocating memory during your program’s runtime, using
it, and freeing it when you are done with it. A well-‐written program uses as little memory as possible. In
Objective-‐C, it can also be seen as a way of distributing ownership of limited memory resources among many
pieces of data and code. When you have finished working through this guide, you will have the knowledge
you need to manage your application’s memory by explicitly managing the life cycle of objects and freeing
them when they are no longer needed.
Although memory management is typically considered at the level of an individual object, your goal is actually
