Rust Compiler Performance Triage

A week dominated by one large improvement and one large regression where luckily the improvement had a larger impact. The regression seems to have been caused by a newly introduced lint that might have performance issues. The improvement was in building rustc with protected visibility which reduces the number of dynamic relocations needed leading to some nice performance gains. Across a large swath of the perf suit, the compiler is on average 1% faster after this week compared to last week.

Triage done by @rylev. Revision range: c8a8c820..27e38f8f

Summary:

(instructions:u) mean range count Regressions ❌ (primary) 0.8% [0.1%, 2.0%] 80 Regressions ❌ (secondary) 1.9% [0.2%, 3.4%] 45 Improvements ✅ (primary) -1.9% [-31.6%, -0.1%] 148 Improvements ✅ (secondary) -5.1% [-27.8%, -0.1%] 180 All ❌✅ (primary) -1.0% [-31.6%, 2.0%] 228

Find the Top 5 Latest Mobile App Development Software in 2025 — Expert Picks by TimD — Tim Digital

Choosing the right mobile app development software in 2025 is more than just a technical decision — it’s a strategic advantage. With the growing pressure to deliver faster, reduce bugs, and maintain UI consistency across devices, developers and companies alike are re-evaluating their tech stacks.

Why the Right Mobile Development Stack Makes All the Difference

Many development teams struggle not because of a lack of skill but due to poor tooling and platform fragmentation. Common issues include:

Too much time spent on duplicate codebases

Difficulty managing bugs across platforms

Low design consistency between iOS and Android versions

A better stack can lead to faster time-to-market, fewer bugs, and improved collaboration across teams.

Snapshot: 5 Game-Changing Mobile Development Frameworks

In 2025, five standout mobile development frameworks are leading the way.

Flutter, backed by Google, offers hot reload, expressive visuals, and UI consistency — making it ideal for cross-platform UI precision. React Native, developed by Meta, is JS/TS-based and features fast refresh and a robust plugin ecosystem, best suited for teams transitioning from web to mobile. .NET MAUI, Microsoft’s enterprise-grade solution, combines native speed with C# and deep integration into the Microsoft ecosystem, perfect for unified experiences across mobile and desktop. For Apple-centric development, Swift stands out with hardware-level API access and deep iOS integration, delivering high-performance, iOS-only applications. Lastly, Kotlin, Google’s preferred language for Android, is known for its concise syntax and Jetpack Compose support, making it the go-to choice for scalable, Android-first projects.

1. Flutter — Deliver Visually Consistent Cross-Platform Apps

Backed by Google, Flutter continues to lead the way for teams needing high-performance mobile apps from a single Dart codebase. With its built-in Skia rendering engine, it doesn’t rely on native UI components — giving you full control over visuals on both Android and iOS.

Why It’s a Top Pick:

Rapid UI iteration with Hot Reload

Mature ecosystem on pub.dev

Excellent for MVPs, startups, and custom-designed apps

2. React Native — A Natural Fit for Web Development Teams

Created by Meta, React Native allows JavaScript developers to build native mobile apps without switching tech stacks. It’s ideal for web teams transitioning into mobile, especially with tools like Expo simplifying builds.

Best Use Cases:

Fast deployment using React-based components

Shared codebase between web and mobile

Lightweight apps needing high iteration cycles

3. .NET MAUI — Microsoft’s Unified Solution for Desktop and Mobile

.NET MAUI enables enterprise-grade cross-platform development using C# and XAML. It compiles to native code, ensuring performance, while simplifying development for organizations already using Microsoft tools and Azure.

Why Enterprises Prefer It:

Strong support for desktop/mobile hybrid builds

Full access to native APIs

Streamlined with Visual Studio and Azure DevOps

4. Swift — The Gold Standard for Native iOS App Development

Developed by Apple, Swift is the go-to for building fluid, fast, and fully integrated iOS apps. Combined with SwiftUI or UIKit, it’s the most reliable way to deliver App Store-ready applications with deep device capabilities.

Ideal For:

iOS-only apps

Products that leverage ARKit, Core ML, or HealthKit

Premium apps requiring pixel-perfect animations

5. Kotlin — For Next-Level Native Android Performance

Endorsed by Google and developed by JetBrains, Kotlin is a modern language designed for Android. It brings null safety, concise syntax, and coroutine-based async capabilities, making it a favorite among Android developers in 2025.

Where It Shines:

Clean migration path from Java

Jetpack Compose support for UI innovation

Great for complex, scalable Android apps

Native vs. Cross-Platform vs. Hybrid — What Should You Choose?

When it comes to choosing the right development approach, your decision should align with your product roadmap, team capabilities, and performance expectations. Native development offers the best UX quality and strong scalability, making it ideal for performance-intensive apps — but it comes with higher maintenance needs and moderate development speed. Cross-platform frameworks like Flutter and React Native strike a balance by allowing faster development, lower maintenance, and good scalability, although UX quality may slightly lag behind native builds. On the other hand, hybrid frameworks such as Ionic are fast to develop and easy to maintain but offer limited user experience and only moderate scalability — making them suitable for basic MVPs or internal tools where performance is not critical.

Expert Tip: If your app relies on camera, AR, or sensors — go native. For time-to-market and design parity, cross-platform tools like Flutter or React Native offer the best ROI.

What to Look for in Mobile App Development Platforms

When selecting mobile development tools in 2025, top agencies and development teams recommend looking for:

Real-time debugging and emulation support

Comprehensive UI libraries

CI/CD compatibility (e.g., App Center, GitHub Actions)

Easy deployment to Play Store and App Store

Third-party plugin support for maps, payments, authentication, etc.

Final Thoughts

Whether you’re launching a feature-rich Android app, building an enterprise mobile suite, or rapidly shipping a cross-platform MVP — choosing the right development platform in 2025 is key to avoiding unnecessary rework and scaling with confidence.

If you’re looking for expert guidance, several agencies — like TimD — Tim Digital — are offering tailored consulting and mobile app solutions built on the most robust tools in the market.

Interview Questions to Ask When Hiring a .NET Developer

The success of your enterprise or web apps can be significantly impacted by your choice of .NET developer. Making the correct decision during interviews is crucial because .NET is a powerful framework that is utilized in a variety of industries, including finance and e-commerce. Dot Net engineers that are not only familiar with the framework but also have the ability to precisely and clearly apply it to real-world business problems are sought after by many software businesses.

These essential questions will assist you in evaluating candidates' technical proficiency, coding style, and compatibility with your development team as you get ready to interview them for your upcoming project.

Assessing Technical Skills, Experience, and Real-World Problem Solving

What experience do you have with the .NET ecosystem?

To find out how well the candidate understands .NET Core, ASP.NET MVC, Web API, and associated tools, start with a general question. Seek answers that discuss actual projects and real-world applications rather than only theory.

Follow-up: What version of .NET are you using right now, and how do you manage updates in real-world settings?

Experience with more recent versions, such as .NET 6 or .NET 8, can result in fewer compatibility problems and improved performance when hiring Dot Net developers.

How do you manage dependency injection in .NET applications?

One essential component of the scalable .NET design is dependency injection. An excellent applicant will discuss built-in frameworks, how they register services, and how they enhance modularity and testability.

Can you explain the difference between synchronous and asynchronous programming in .NET?

Performance is enhanced by asynchronous programming, particularly in microservices and backend APIs. Seek a concise description and examples that make use of Task, ConfigureAwait, or async/await.

Advice: When hiring backend developers, candidates who are aware of async patterns are more likely to create apps that are more efficient.

What tools do you use for debugging and performance monitoring?

Skilled developers know how to optimize code in addition to writing it. Check for references to Postman, Application Insights, Visual Studio tools, or profiling tools such as dotTrace.

This demonstrates the developer's capacity to manage problems with live production and optimize performance.

How do you write unit and integration tests for your .NET applications?

Enterprise apps require testing. A trustworthy developer should be knowledgeable about test coverage, mocking frameworks, and tools like xUnit, NUnit, or MSTest.

Hiring engineers with strong testing practices helps tech organizations avoid expensive errors later on when delivering goods on short notice.

Describe a time you optimized a poorly performing .NET application.

This practical question evaluates communication and problem-solving abilities. Seek solutions that involve database query optimization, code modification, or profiling.

Are you familiar with cloud deployment for .NET apps?

Now that a lot of apps are hosted on AWS or Azure, find out how they handle cloud environments. Seek expertise in CI/CD pipelines, containers, or Azure App Services.

This is particularly crucial if you want to work with Dot Net developers to create scalable, long-term solutions.

Final Thoughts

You may learn more about a developer's thought process, problem-solving techniques, and ability to operate under pressure via a well-structured interview. These questions provide a useful method to confidently assess applicants if you intend to hire Dot Net developers for intricate or high-volume projects.

The ideal .NET hire for expanding tech organizations does more than just write code; they create the framework around which your products are built.

Why Testing and Debugging Matter

Testing and debugging help catch issues early in development, reducing maintenance costs and ensuring a stable application. Angular 19 offers powerful tools for both unit and end-to-end (E2E) testing, allowing developers to write and execute tests efficiently.

Types of Testing in Angular 19

Unit Testing: Testing individual components, services, or functions.

Integration Testing: Verifying the interaction between different components.

End-to-End (E2E) Testing: Testing the entire application workflow.

Performance Testing: Ensuring the application meets performance benchmarks.

Testing Tools for Angular 19

Karma: Test runner to execute unit tests.

Jasmine: Behavior-driven development framework.

Jest: An alternative test framework known for faster unit test execution.

Cypress: Modern and popular E2E testing framework replacing Protractor.

Playwright: An alternative E2E testing tool for cross-browser testing.

Setting Up Unit Testing

Angular projects come pre-configured with Jasmine and Karma. To create a new component with test files:

ng generate component my-component

This generates a my-component.component.spec.ts file, which is the unit test file.

Example Unit Test

import ComponentFixture, TestBed from '@angular/core/testing'; import MyComponent from './my-component.component'; describe('MyComponent', () => let component: MyComponent; let fixture: ComponentFixture<MyComponent>; beforeEach(async () => await TestBed.configureTestingModule( declarations: [MyComponent], ).compileComponents(); fixture = TestBed.createComponent(MyComponent); component = fixture.componentInstance; fixture.detectChanges(); ); it('should create the component', () => expect(component).toBeTruthy(); ); );

Running Unit Tests

Use the following command to run unit tests:

ng test

  End-to-End (E2E) Testing with Cypress

Protractor has been deprecated in Angular 15+, and Cypress has become a preferred tool for E2E testing in Angular 19 applications.

Setting Up Cypress

Install Cypress using the Angular CLI or npm:

ng add @cypress/schematic

To run Cypress tests:

npx cypress open

Sample E2E Test with Cypress

describe('App Homepage', () => it('should display the welcome message', () => cy.visit('/'); cy.contains('h1', 'Welcome to Angular 19!'); ); );

    Debugging Angular 19 Applications

Debugging is crucial for identifying and fixing issues during development. Angular 19 provides multiple tools to aid in debugging.

1. Angular DevTools

Angular DevTools is a Chrome extension that offers profiling and debugging capabilities.

Component Explorer: View component hierarchy.

Profiler: Analyze performance bottlenecks.

Change Detection Debugging: Monitor change detection cycles.

2. Console Logging

Logging with console.log() is a quick way to inspect data:

console.log('Component initialized', this.data);

3. Breakpoints in Browser DevTools

Set breakpoints directly in TypeScript files to pause execution and inspect variables.

4. Debugging RxJS Streams

Use the tap() operator to inspect stream data:

of(1, 2, 3).pipe( tap(value => console.log('Value:', value)) ).subscribe();

  Best Practices for Testing and Debugging

Isolate Unit Tests: Keep unit tests independent from external services.

Mock Dependencies: Use mocks for HTTP and service calls to ensure consistent results.

Automate Testing: Integrate testing into your CI/CD pipeline.

Code Coverage Reports: Use coverage reports to identify untested code.

Debug Efficiently: Use Angular DevTools for advanced debugging.

Test for Edge Cases: Ensure tests cover all possible scenarios.

Final Thoughts

Testing and debugging are indispensable for maintaining robust Angular 19 applications. By implementing best practices and leveraging tools like Jasmine, Karma, Cypress, and Angular DevTools, developers can ensure their applications are reliable, maintainable, and performant.

By utilizing offbeat LED control cards in combination with Receiving cards, one can make a smooth and proficient framework that permits for high-quality visual yield. This integration handle includes both equipment and program components, making it vital to take after a orderly approach to guarantee consistent communication between these devices.

Understanding the Components

1. Async LED Control Card: The Async LED Control Card serves as the heart of the LED display framework. It oversees the information stream from the controller to the receiving cards, interpreting the substance into a arrange that can be caught on by the LED board. This sort of card is particularly valuable in expansive establishments, as it can back numerous displays with negligible delay. "Async" alludes to offbeat communication, meaning the control card does not require synchronization with other gadgets to work correctly.

2. LED Receiving Card: The LED Receiving Card is capable for Receiving the information transmitted from the LED control card and passing it to the LED modules. These cards interpret the data and guarantee that the adjust picture or video is displayed on the screen. Different receiving cards are regularly utilized in a expansive display setup to disseminate the substance over the boards equitably. The Receiving cards communicate with each other in a arrangement, so the display is synchronized.

Step-by-Step Integration Process

1. Framework Plan and Planning

Before beginning the integration, it is fundamental to plan the framework format. Decide the number of LED boards and modules, as well as the required determination. Based on this data, you can select the suitable Async LED control card and LED receiving cards that bolster the vital capacity.

• Determine the number of control cards: For bigger displays, you might require different control cards to handle the information stream. Each control card can back a particular number of receiving cards, depending on the display's measure and resolution.

• Select the rectify Receiving cards: Select receiving cards that coordinate the LED board determinations and the control card’s yield. Guarantee that they are congruous with the sort of LED modules you are using. 2. Physical Installation

Once the framework plan is prepared, continue with the physical establishment of the control cards and Receiving cards.

• Install the Async LED control card: Put the control card at the center of the framework, more often than not associated to the primary server or media player that will produce the display content.

• Connect LED receiving cards to the LED modules: Each Receiving card is associated to the LED modules utilizing communication cables. Guarantee that the wiring is done accurately, paying near consideration to the course of flag flow.

• Power Supply: Both the control and receiving cards require a steady control supply. Make beyond any doubt the control dissemination is done appropriately to maintain a strategic distance from control over-burdens or shortages.

3. Wiring and Communication Setup

The communication between the Async LED control card and LED Receiving cards is pivotal for legitimate information transfer.

• Signal Association: Utilize solid flag transmission cables like Ethernet or DVI cables to interface the control card to the receiving cards. The control card sends out signals containing the display information, and the Receiving cards translate and transfer this information to the individual LED modules.

• Network Setup: In a few frameworks, the Receiving cards may be associated through a organize. In such cases, make beyond any doubt the communication conventions between the control cards and Receiving cards are arranged properly.

4. Program Configuration

After the physical setup, the program setup plays a basic part in fine-tuning the LED system.

• Set up the LED control computer program: Utilize the given computer program with the Async LED control card to design and outline the display yield. This program permits you to alter the determination, pixel thickness, and other display parameters.

• Map Receiving Cards to LED Modules: The computer program will permit you to outline each LED Receiving Card to particular areas of the display, guaranteeing that the information is accurately transmitted to the comparing LED panels.

• Test the Framework: Run a test grouping to confirm that all Receiving cards are Receiving the rectify information and that the LED modules are displaying the substance as anticipated. Alter any setups as essential to accomplish ideal performance.

5. Support and Troubleshooting

Once the framework is up and running, intermittent upkeep is required to guarantee ideal performance.

• Regular Checkups: Assess cables, associations, and control supplies for wear and tear.

• Firmware Upgrades: Guarantee that both the Async LED control card and LED Receiving cards are running the most recent firmware for made strides execution and security.

• Troubleshooting: If any segment of the display breakdowns, distinguish the issue by checking the computer program and equipment setup. You can utilize symptomatic devices to separate any defective Receiving cards or communication issues.

Conclusion

Integrating Async LED control cards with LED Receiving cards is an proficient way to oversee and control huge LED display frameworks. With cautious arranging, establishment, and arrangement, these components work together to guarantee a smooth and high-quality display. Whether for promoting, computerized signage, or amusement, the combination of these advances can offer adaptability, versatility, and noteworthy visual execution. Legitimate integration not as it were upgrades the seeing encounter but too guarantees long-term unwavering quality and support effectiveness.

Quote of the Week

Panstromek: I remember reading somewhere (probably here) that borrow checking has O(n^3) asymptotic complexity, relative to the size of the function.

Nadrieril: Compared to match exhaustiveness which is NP-hard and trait solving which is undecidable, a polynomial complexity feels refreshingly sane.

HarmonyOS NEXT Practical: Awakening the Camera

Objective: To evoke camera photography and recording, and display the captured images and videos.

The application can call CameraPicker to take photos or record videos without applying for camera permissions.

The camera interactive interface of CameraPicker is provided by the system. After the user clicks the capture and confirmation button, the application of CameraPicker is called to obtain the corresponding photos or videos.

If application developers only need to obtain real-time photos or videos, they can easily use CameraPicker capabilities to achieve this.

Due to the fact that the shooting and confirmation of photos are actively confirmed by users, application developers do not need to apply for relevant permissions to operate the camera.

cameraPicker.pick interface [code] pick(context: Context, mediaTypes: Array, pickerProfile: PickerProfile): Promise [/code]

Pull up the camera selector and enter the corresponding mode according to the media type. The operation ends and the result is obtained in the form of a Promise.

PickerProfile： Configuration information for the camera selector. PickerProfile attribute

cameraPosition: The position of the camera.

saveUri: The URI used to save configuration information. Please refer to the file URI for the default value.

VideoDuration: The maximum duration of recording in seconds.

describe

The saveUri of PickerProfile is an optional parameter. If this option is not configured, the photos and videos taken will be saved to the media library by default.

If you do not want to store photos and videos in the media library, please configure the file path in the application sandbox by yourself.

The file in the application sandbox must be an existing and writable file. After passing the URI of this file into the picker interface, it is equivalent to granting the system camera read and write permissions for the file. After the system camera finishes shooting, it will overwrite and write this file.

PickerResult： The processing result of the camera selector. PickerResult attribute

resultCode: The processed result returns 0 for success and -1 for failure.

resultUri: The returned URI address. If saveUri is empty, resultUri is the public media path. If saveUri is not empty and has write permission, resultUri is the same as saveUri. If saveUri is not empty and does not have write permission, the resultUri cannot be obtained.

mediaType: The returned media type.

Actual combat: CameraPickerPage [code] import { camera, cameraPicker as picker } from '@kit.CameraKit' import { fileIo, fileUri } from '@kit.CoreFileKit'

@Entry @Component struct CameraPickerPage { @State imgSrc: string = ''; @State videoSrc: string = ''; @State isShowImage: boolean = false

build() { Column({ space: 10 }) { Text('CameraPicker Demo') Row({ space: 10 }){ Button('拍照') .onClick(async () => { let pathDir = getContext().filesDir; let fileName = `${new Date().getTime()}` let filePath = pathDir + `/${fileName}.tmp` fileIo.createRandomAccessFileSync(filePath, fileIo.OpenMode.CREATE); let uri = fileUri.getUriFromPath(filePath); let pickerProfile: picker.PickerProfile = { cameraPosition: camera.CameraPosition.CAMERA_POSITION_BACK, saveUri: uri }; let result: picker.PickerResult = await picker.pick(getContext(), [picker.PickerMediaType.PHOTO], pickerProfile); console.info(`picker resultCode: ${result.resultCode},resultUri: ${result.resultUri},mediaType: ${result.mediaType}`); if (result.resultCode == 0) { if (result.mediaType === picker.PickerMediaType.PHOTO) { this.imgSrc = result.resultUri; this.isShowImage = true } else { this.videoSrc = result.resultUri; } } }) Button('录视频') .onClick(async () => { let pathDir = getContext().filesDir; let fileName = `${new Date().getTime()}` let filePath = pathDir + `/${fileName}.tmp` fileIo.createRandomAccessFileSync(filePath, fileIo.OpenMode.CREATE); let uri = fileUri.getUriFromPath(filePath); let pickerProfile: picker.PickerProfile = { cameraPosition: camera.CameraPosition.CAMERA_POSITION_BACK, saveUri: uri }; let result: picker.PickerResult = await picker.pick(getContext(), [ picker.PickerMediaType.VIDEO], pickerProfile); console.info(`picker resultCode: ${result.resultCode},resultUri: ${result.resultUri},mediaType: ${result.mediaType}`); if (result.resultCode == 0) { if (result.mediaType === picker.PickerMediaType.PHOTO) { this.imgSrc = result.resultUri; } else { this.videoSrc = result.resultUri; this.isShowImage = false } } }) } if (this.imgSrc != '' || this.videoSrc != '') { if (this.isShowImage) { Image(this.imgSrc).width(200).height(200).backgroundColor(Color.Black).margin(5); } else { Video({ src: this.videoSrc }).width(200).height(200).autoPlay(true); } } } .height('100%') .width('100%')

Hiring React JS Developers? Here's the Playbook Every U.S. Manager Needs

The preferred front-end library for contemporary web development is React.js. Businesses use React because of its performance and adaptability, whether they're creating an internal tool, a customer-facing app, or a dynamic dashboard. Finding the proper expertise, however, is becoming more difficult as demand rises. This guide will help you confidently handle the process of hiring Reactjs developers.

The need to employ fast without compromising quality is significant for U.S. tech companies. This is how to do it correctly.

The Smart, Practical Guide to Building Your Front-End Dream Team

Know exactly what you need

Not every React developer has the same set of abilities. While some are better at state management, API integration, or speed optimization, others are better at UI/UX.

Prior to searching, carefully describe the scope of your project:

Are you updating an old app or creating a new one?

Do you require integration with a certain CMS or backend?

Will the developer be a member of a larger team or operate alone?

Hiring Reactjs developers that are truly a good fit will be simpler with this clarity, which will save time and lower turnover.

Focus on real-world expertise

A well-crafted resume is insufficient. Ask for GitHub links, live projects, or case studies. Since React changes rapidly, developers that stay up to date with the latest best practices—such as hooks, context API, and component libraries like MUI or Chakra—are more useful than those who don't.

People who can demonstrate their work, rather than just tell you about it, are frequently the ideal hiring for software companies. Examine their prior work and find out how they handled particular issues.

Assess soft skills and team fit

Additionally, a proficient React developer must be able to communicate effectively, particularly when working with product managers, backend engineers, or designers. Soft skills are important whether you're hiring locally or remotely.

Seek applicants who are organized, responsive, and at ease using async tools like GitHub, Trello, and Slack if you're hiring software developers from multiple time zones or working with a distributed team.

Use the right hiring channels

It can take a lot of time to find talent on your own. The procedure might be expedited by a reputable IT staffing agency that provides AI-vetted applicants with validated abilities. Agencies may frequently connect you with developers that have appropriate industry or product experience since they understand what tech firms need.

Bonus: If you're not sure you want to commit to full-time employment right away, agencies frequently offer flexible contracts or trial periods.

Don’t skip the technical evaluation

A quick technical exam or pair programming session can show how a developer thinks and solves problems, even with excellent portfolios. Just make sure it matches the type of work they will be doing on your team; it doesn't have to be complicated.

By taking this step, you may be sure that you're not employing someone based solely on their appearance or demeanour.

Closing Thoughts

It takes more than simply a job posting to successfully hire Reactjs developers; you also need a plan. Determine your needs, evaluate your practical abilities, and, if needed, think about seeking professional assistance. The correct hire can strengthen your product, increase delivery speed, and enhance user experience. It is not just wise, but also necessary for tech organizations to have a clear, repeatable hiring playbook if they want to remain competitive.
