None of them are doing well. They all expect to be out of business soon. What I discovered was that web media companies can’t count on any of the traffic coming from Google or Facebook anymore. Very few, even one that are frugally run, are capable of surviving on the traffic that remains. The problem doesn’t seem limited to a few sites. What seems to have happened is that Google tried to “fix” their search engine results by using machine learning to rank sites.Intenty: check phone less - Intenty helps you build a healthier relationship with your phone through gentle awareness prompts that appear right when you need them – at unlock.

PriceSimplifying disposal by using the using statementYou can simplify the code that needs to check for anullobject and then call itsDisposemethod by using theusingstatement. Generally, I would recommend usingusingrather than manually callingDisposebecause it’s less code to write, unless you need a greater level of control.Confusingly, there are two uses for theusingkeyword: importing a namespace and generating afinallystatement that callsDisposeon an object implementingIDisposable.The compiler changes ausingstatement block into atry-finallystatement without acatchstatement. You can use nestedtrystatements; so, if you do want to catch any exceptions, you can, as shown in the following code example:using (FileStream file2 = File.OpenWrite(Path.Combine(path, "file2.txt"))){using (StreamWriter writer2 = new StreamWriter(file2)){try{writer2.WriteLine("Welcome, .NET!");}catch(Exception ex){WriteLine($"{ex.GetType()} says {ex.Message}"); }} // Automatically calls Dispose if the object is not null.} // Automatically calls Dispose if the object is not null.You can even simplify the code further by not explicitly specifying the braces and indentation for theusing statements, as shown in the following code...read more.Read the ‘C# 12 and .NET 8 – Modern Cross-Platform Development Fundamentals’ book now!What's Happening in Mobile Development?Your dose of the latest releases, news and happenings in the Mobile Development industry!AppleInside the AudioLab: How Apple developed the world’s first end‑to‑end hearing health experience - The Audio Lab is the hub for the design, measurement, tuning, and validation of all of Apple’s products with speakers or microphones.

This is why - Over the years, Flutter has attracted millions of developers who built user interfaces across every platform. Flutter began as a UI toolkit for mobile - iOS and Android, only. Then Flutter added support for web. Finally, Flutter expanded to Mac, Windows, and Linux. Across this massive expansion of scope and responsibility, the Flutter team has only marginally increased its size. To help expand Flutter's available labor, and accelerate development, we're creating a fork of Flutter, called Flock.Apple is Killing Swift - Swift was a great language, but it has fallen far from its original vision.

Here's What to Use Instead - MediaQuery is not the best tool for responsive design in Flutter. Actually, it's far from it. I know, it’s tempting to scale widgets based on the percentage of screen size and call it a day. But using MediaQuery for sizing, while seemingly simple, is a slippery slope that often leads to weird and problematic layouts. Unfortunately, many beginners fall into the trap of using fractional sizing because it seems like an easy solution at first. But if you’re serious about creating responsive apps, it’s time to reconsider how you approach this.Flutter is Getting a Makeover! Meet Flock, the New Community-Driven Framework Set to Change Everything - Flutter has empowered millions of developers to build seamless, cross-platform apps, but as demand grows, cracks are beginning to show. Despite its popularity, the Flutter team is stretched too thin, facing backlogs that can leave bugs and feature requests unresolved for too long. This bottleneck frustrated users across the community and led to the birth of a new solution: Flock — a fork of Flutter developed by the community for the community. Flock represents a community-driven effort to overcome the limitations Flutter currently faces. With a more agile review process, enhanced support, and a welcoming approach to contributions, Flock aims to provide a more responsive alternative to Flutter, shaped by those who use it the most.12 Top Flutterflow App Development Agencies for Any Use Case - This article is intended for everyone interested in Flutterflow app development.

If your project or target relies on the previous variable, you should update it to use $TOOLCHAIN_DIR. To perform this replacement, you can add the following code snippet at the end of your project’s Podfile. This error was on a MacOS v14 (Sonoma), XCode 15.4, Swift 5.0 regarding the Firebase and Firebase Analytics Pods.How to make your Web Page Responsive - A good well-designed responsive web page makes sure that the user has an optimal view experience and a uniform user experience irrespective of the device the user is using.

Though challenging, this approach offers full control over the rendering pipeline, down to each byte and command submitted to the GPU on each frame. This blog covers helps you do just that!Large language models reduce public knowledge sharing on online Q&A platforms - Large language models (LLMs) are a potential substitute for human-generated data and knowledge resources. This substitution, however, can present a significant problem for the training data needed to develop future models if it leads to a reduction of human-generated content. In this work, we document a reduction in activity on Stack Overflow coinciding with the release of ChatGPT, a popular LLM. Mobile App Development TutorialAn excerpt from ‘C# 12 and .NET 8 – Modern Cross-Platform Development Fundamentals’ By Mark J. PriceEnabling lazy loadingLazy loading was introduced in EF Core 2.1, and it can automatically load missing related data. To enable lazy loading, developers must: Reference a NuGet package for proxies and Configure lazy loading to use a proxy.Let’s see this in action:In theWorkingWithEFCoreproject, add a package reference for EF Core proxies, as shown in the following markup:<PackageReference Version="8.0.0"Include="Microsoft.EntityFrameworkCore.Proxies" />Build theWorkingWithEFCoreproject to restore packages.InNorthwindDb.cs, at the bottom of theOnConfiguringmethod, call an extension method to use lazy loading proxies, as shown in the following code:optionsBuilder.UseLazyLoadingProxies();Now, every time the loop enumerates and an attempt is made to read theProductsproperty, the lazy loading proxy will check if they are loaded. If they’re not loaded, it will load them for us “lazily” by executing aSELECTstatement to load just that set of products for the current category, and then the correct count will be returned to the output.Run the code and note that the product counts are now correct. But you will see that the problem with lazy loading is that multiple round trips to the database server are required to eventually fetch all the data. For example, getting all the categories and then getting the products for the first category,Beverages, requires the execution of two SQL commands, as shown in the following partial output:dbug: 05/03/2022 13:41:40.221 RelationalEventId.CommandExecuting[20100] (Microsoft.EntityFrameworkCore.Database.Command)Executing DbCommand [Parameters=[], CommandType='Text', CommandTimeout='30']SELECT "c"."CategoryId", "c"."CategoryName", "c"."Description"FROM "Categories" AS "c"dbug: 05/03/2022 13:41:40.331 RelationalEventId.CommandExecuting[20100] (Microsoft.EntityFrameworkCore.Database.Command)Executing DbCommand [Parameters=[@__p_0='1'], CommandType='Text', CommandTimeout='30']SELECT "p"."ProductId", "p"."CategoryId", "p"."UnitPrice", "p"."Discontinued", "p"."ProductName", "p"."UnitsInStock"FROM "Products" AS "p"WHERE NOT ("p"."Discontinued") AND "p"."CategoryId" = @__p_0Beverages has 11 products. ...Read the ‘C# 12 and .NET 8 – Modern Cross-Platform Development Fundamentals’ book now!What's Happening in Mobile Development?Your dose of the latest releases, news and happenings in the Mobile Development industry!AppleApple Unveils New iPad Mini With A17 Pro Chip and Apple Intelligence - Apple announceda significant upgrade to the iPad mini, now featuring an A17 Pro chip and support for the company's new Apple Intelligence system.

To explain this better, let's go back in time!React Native Dynamic App Icons - This article demonstrates a practical implementation of dynamic app icon changing in React Native, utilising thereact-native-change-iconlibrary. It serves as a guide and example for developers looking to incorporate icon-switching functionality into their iOS and Android applications.NativeFlow: A Tailwind-Like, Object-Based React Native UI Library - In the world of React Native development, UI styling can sometimes be a pain point, especially for those used to the flexibility and simplicity of utility-first CSS frameworks like Tailwind. You know the drill — hours spent wrestling with babel setups, styles, tweaking tiny details, and hoping it looks good on both iOS and Android. Many existing solutions rely on wrapping Tailwind with custom Babel setups or trying to make it work inside React Native's ecosystem. But (let’s be real), these approaches often add extra complexity, unsupported properties, or completely miss out on platform-specific APIs. That’s where NativeFlow comes in.10 Software Design and Programming Best Practices for Developers - Software design and System Design a critical aspect of the development process that can significantly impact the success and maintainability of a project.

The company does not offer Australians an opt out option like it does in the EU, because it has not been required to do so under privacy law.Zero-Click Calendar invite: Critical zero-click vulnerability chain in macOS - I found a zero-click vulnerability in macOS Calendar, which allows an attacker to add or delete arbitrary files inside the Calendar sandbox environment. This could lead to many bad things including malicious code execution which can be combined with security protection evasion with Photos to compromise users’ sensitive Photos iCloud Photos data. Apple hasfixedall the vulnerabilities between October 2022 and September 2023.LLMs Will Always Hallucinate, and We Need to Live With This - As Large Language Models become more ubiquitous across domains, it becomes important to examine their inherent limitations critically. This work argues that hallucinations in language models are not just occasional errors but an inevitable feature of these systems. We demonstrate that hallucinations stem from the fundamental mathematical and logical structure of LLMs. It is, therefore, impossible to eliminate them through architectural improvements, dataset enhancements, or fact-checking mechanisms. Our analysis draws on computational theory and Godel's First Incompleteness Theorem, which references the undecidability of problems like the Halting, Emptiness, and Acceptance Problems. Mobile App Development TutorialAn excerpt from ‘C# 12 and .NET 8 – Modern Cross-Platform Development Fundamentals’ By Mark J. PriceUnderstanding data seeding with the Fluent APIAnother benefit of the Fluent API is to provide initial data to populate a database. EF Core automatically works out what insert, update, or delete operations must be executed.For example, if we wanted to make sure that a new database has at least one row in theProducttable, then we would call theHasDatamethod, as shown in the following code:modelBuilder.Entity<Product>().HasData(new Product{ProductId = 1,ProductName = "Chai",UnitPrice = 8.99M});Calls toHasDatatake effect either during a data migration executed by the commanddotnet ef database updateor when you call theDatabase.EnsureCreatedmethod.Our model will map to an existing database that is already populated with data, so we will not need to use this technique in our code....read more.Read the ‘C# 12 and .NET 8 – Modern Cross-Platform Development Fundamentals’ book now!What's Happening in Mobile Development?Your dose of the latest releases, news and happenings in the Mobile Development industry!AppleTN3111: iOS Wi-Fi API overview - Explore the various Wi-Fi APIs available on iOS and their expected use cases. iOS does not have a general-purpose API for Wi-Fi scanning and configuration. However, it does support a wide range of special-purpose Wi-Fi APIs. This technote lists some use cases supported by those special-purpose APIs.AndroidAttestation format change for the Android FIDO2 API - In 2019 we introduceda FIDO2 API, adopted by many leading developers, which allows users to generate an attested, device-boundFIDO2 credential on Android devices. Since this launch, Android has generated an attestation statement based on theSafetyNet API. As the underlying SafetyNet API is beingdeprecated, the FIDO2 API must move to a new attestation scheme based on hardware-backed key attestation. This change will require action from developers using the FIDO2 API to ensure a smooth transition. The FIDO2 API is closely related to, but distinct from, thepasskeys APIand is invoked by setting theresidentKeyparameter todiscouraged. While our goal is over time tomigrate developers to the passkey API, we understand that not all developers who are currently using the FIDO2 API are ready for that move and we continue working on ways to converge these two APIs.Developer Preview: Desktop windowing on Android Tablets - To empower tablet users to get more done, we're enhancing freeform windowing, allowing them to run multiple apps simultaneously and resize windows for optimal multitasking.

Mobile App Development TutorialAn excerpt from ‘C# 12 and .NET 8 – Modern Cross-Platform Development Fundamentals’ By Mark J. PriceSimplifying disposal by using the using statementYou can simplify the code that needs to check for anullobject and then call itsDisposemethod by using theusingstatement. Generally, I would recommend usingusingrather than manually callingDisposebecause it’s less code to write, unless you need a greater level of control.Confusingly, there are two uses for theusingkeyword: importing a namespace and generating afinallystatement that callsDisposeon an object implementingIDisposable.The compiler changes ausingstatement block into atry-finallystatement without acatchstatement. You can use nestedtrystatements; so, if you do want to catch any exceptions, you can, as shown in the following code example:using (FileStream file2 = File.OpenWrite(Path.Combine(path, "file2.txt"))){using (StreamWriter writer2 = new StreamWriter(file2)){try{writer2.WriteLine("Welcome, .NET!");}catch(Exception ex){WriteLine($"{ex.GetType()} says {ex.Message}"); }} // Automatically calls Dispose if the object is not null.} // Automatically calls Dispose if the object is not null.You can even simplify the code further by not explicitly specifying the braces and indentation for theusing statements, as shown in the following code...read more.Read the ‘C# 12 and .NET 8 – Modern Cross-Platform Development Fundamentals’ book now!What's Happening in Mobile Development?Your dose of the latest releases, news and happenings in the Mobile Development industry!AppleiOS 18 is available today, making iPhone more personal and capable than ever - iOS 18is now available, bringing iPhone users around the world new ways to personalize their iPhone with deeper customization to the Home Screen and Control Center; the biggest-ever redesign to Photos, making it even easier to find and relive special moments; and major enhancements to Messages and Mail.

However, achieving these goals requires careful planning and execution. Captivating visuals, intuitive navigation, and interactive gameplay are essential components that must be seamlessly integrated to ensure players enjoy and become fully immersed in their gaming experience. Conducting thorough user research and asking pertinent questions is instrumental in gaining deep insights into what resonates with your target audience. In this blog, we will discover what user experience testing is and why you must conduct it totest gaming apps.Why use a well-structured architecture in Android? - The Android Operating System (AOSP) is designed to enhance the user experience by managing system resources efficiently. To maintain optimal performance, it may terminate processes as needed. If it "decides" to kill your process, there's little you can do to prevent it. Therefore, maintaining a consistent architecture is crucial to avoid data loss. Understanding the principle of separation of concerns is essential as you embark on your journey with Android architecture.Quantum Computing: What It Means for Mobile App Development - The landscape of computing is evolving, and quantum computing is at the forefront of this transformation.

In this blog, we’ll explore what quantum computing is, how it could impact mobile app development, and what you need to know to stay ahead.Why Choose Flutter Over React Native? A Deep Dive into the Pros and Cons - When it comes to cross-platform mobile development, Flutter and React Native stand out as the two most popular frameworks. Both have large, passionate communities and offer developers the ability to write code once and deploy it across multiple platforms. However, choosing between Flutter and React Native can be challenging, especially for developers or companies that need to make strategic decisions that will affect their product’s future. In this blog, we'll explore why you might want to consider Flutter over React Native, focusing on unique strengths rather than simply declaring one as superior.Understanding Dependency Injection - Imagine you're working on an app that requires various components to interact seamlessly. You’ve written a class to handle user authentication, but it directly creates instances of several dependencies network services, data storage, and logging utilities. It works well at first, but as the project grows, testing becomes a nightmare. Every time you make a change, you must modify multiple classes, and mocking these dependencies for unit tests feels like a battle. You start to realize that your tightly coupled code is dragging down the entire project. This is whereDependency Injectioncomes to the rescue.Mobile App Dev ReposCheck this space for new repos, projects and tools each week!

It explores false memory induction through suggestive questioning in Human-AI interactions, simulating crime witness interviews. Four conditions were tested: control, survey-based, pre-scripted chatbot, and generative chatbot using a large language model (LLM). Participants (N=200) watched a crime video, then interacted with their assigned AI interviewer or survey, answering questions including five misleading ones. False memories were assessed immediately and after one week. Results show the generative chatbot condition significantly increased false memory formation, inducing over 3 times more immediate false memories than the control and 1.7 times more than the survey method.Dawarich - Dawarich is a self-hosted web application to replace Google Timeline (aka Google Location History). It allows you to import your location history from Google Maps Timeline and Owntracks, view it on a map and see some statistics, such as the number of countries and cities visited, and distance traveled.Song Pong - Synchronizing pong to music with constrained optimization. In classic pong a ball bounces off of paddles in a steady rhythm. What if we synchronize the bounces to the beat of a song, making the paddles dance? To make this possible we alter the physics of the game so that the ball moves at a constant speed, and paddles can move anywhere on their respective halves of the screen.Canva says its new AI features justify raising subscription prices by 300% - Your favorite design hack is about to get more expensive. Canva, the popular design platform that launched in Australia in 2012, just instituted price hikes for its “Teams” subscription.

But if it doesn't, and especially if your gender is beyond the woman-man binary, you constantly notice user interfaces that exclude you. So, in this blog post, I'll discuss the concept of gender a bit and then demonstrate one way to build a more inclusive gender selection with Jetpack Compose. Setting Up ViewCode Projects for Versions Below iOS 13 - In iOS development, a significant change was introduced with iOS 13, bringing theSceneDelegateto facilitate multi-window support on iPads and other functionalities. However, when working with earlier versions of iOS, theSceneDelegateis not used, and the initial setup of the application must be done directly in theAppDelegate. In this article, I'll guide you through the process of configuring your iOS application using theAppDelegate, ensuring compatibility with versions prior to iOS 13.The Future of IoT and Android: What Lies Ahead - The Internet of Things (IoT) has emerged as a transformative force in the digital landscape, connecting billions of devices worldwide. From smart homes to industrial automation, IoT is revolutionizing how we interact with technology and the environment around us. Android, as one of the most widely used operating systems, plays a crucial role in enabling and enhancing IoT solutions. In this blog, we'll delve into the intricacies of IoT, its key components, and how Android is at the forefront of this technological revolution, with best practices for connecting and managing IoT devices through mobile apps.Android vs iOS - After using Android phones for almost all the years and iPhone for about 3 months, here is an analysis comparing the features of both. I have used stock Android on Pixel and iOS on iPhone 15 Pro, so best of both worlds. A big factor in this comparison is that it just discusses the features of Android and iOS, not the complete infrastructure. I am pretty sure that if you add a Macbook, Airpods, and an iPad, the table might look way different. The following comparison lists Android 14 vs iOS 17.6 (just a few days before the release of iOS 18).Optimizing Performance in React Native App - Cross-platform development which allows us to create an app for both iOS and Android with just one codebase has recently surged in popularity. However, with the benefits comes the responsibility to ensure they perform flawlessly across both platforms and all supported devices.

A recent experiment in a high school provides a cautionary tale. Researchers at the University of Pennsylvania found that Turkish high school students who had access to ChatGPT while doing practice math problems did worse on a math test compared with students who didn’t have access to ChatGPT. Those with ChatGPT solved 48 percent more of the practice problems correctly, but they ultimately scored 17 percent worse on a test of the topic that the students were learning.Ismyblueyourblue? - People have different names for the colors they see.Language can affect how we memorize and name colors. This is a color naming test designed to measure your personal blue-green boundary. Color perception is tricky to measure–vision scientists use specialized calibrated equipment to color perception. Graphic designers use physical color cards, such as thosemade by Pantone, so that they can communicate colors unambiguously. Here we use your monitor or phone to test how you categorize colors, which is far from perfect, since your calibration may differ from mine.Chromatone - Chromatone is an open-source research and design project to explore, develop and implement the scientific way of visual music education, communication and performance. Imagine if we once agree on a standard way to interconnect colors and notes? It will empower our music perception with vision, most humans primary sensory channel, especially in our modern screen time. Why not view music the visual way today? Let's explore 12 notes, 12 colors and infinite space of their possible combinations. Mobile App Development TutorialAn excerpt from ‘C# 12 and .NET 8 – Modern Cross-Platform Development Fundamentals’ By Mark J. PriceGood practice with collectionsSince .NET 1.1, types likeStringBuilderhave had a method namedEnsureCapacitythat can presize its internal storage array to the expected final size of thestring. This improves performance because it does not have to repeatedly increment the size of the array as more characters are appended.Since .NET Core 2.1, types likeDictionary<T>andHashSet<T>have also hadEnsureCapacity.In .NET 6 and later, collections likeList<T>,Queue<T>, andStack<T>now have anEnsureCapacitymethod too, as shown in the following code:List<string> names = new();names.EnsureCapacity(10_000);// Load ten thousand names into the list.Let’s say you need to create a method to process a collection. For maximum flexibility, you could declare the input parameter to beIEnumerable<T>and make the method generic, as shown in the following code:void ProcessCollection<T>(IEnumerable<T> collection){// Process the items in the collection,// perhaps using a foreach statement.}I could pass an array, a list, a queue, or a stack, containing any type, likeint,string,Person, or anything else that implementsIEnumerable<T>, into this method and it will process the items. However, the flexibility to pass any collection to this method comes at a performance cost.One of the performance problems withIEnumerable<T>is also one of its benefits: deferred execution, also known as lazy loading. Types that implement this interface do not have to implement deferred execution, but many do.But the worst performance problem withIEnumerable<T>is that the iteration must allocate an object on the heap. To avoid this memory allocation, you should define your method using a concrete type, as shown highlighted in the following code:void ProcessCollection<T>(List<T> collection){// Process the items in the collection,// perhaps using a foreach statement.}This will use theList<T>.Enumerator GetEnumerator()method, which returns astruct, instead of theIEnumerator<T> GetEnumerator()method, which returns a reference type. Your code will be two to three times faster and require less memory. As with all recommendations related to performance, you should confirm the benefit by running performance tests on your actual code in a product environment.Read the ‘C# 12 and .NET 8 – Modern Cross-Platform Development Fundamentals’ book now!What's Happening in Mobile Development?Your dose of the latest releases, news and happenings in the Mobile Development industry!AndroidAndroid 15 is released to AOSP - Today we're releasing Android 15 and making the source code available at theAndroid Open Source Project(AOSP).
