Comparing Native vs Cross-Platform Desktop App Development Services

In today’s rapidly evolving technological landscape, businesses and developers alike are constantly looking for ways to optimize their software development processes. One of the most crucial decisions in desktop software development is whether to go for native or cross-platform app development. Both approaches offer unique advantages and challenges. In this blog, we will compare native vs cross-platform desktop app development services to help you make an informed decision based on your specific needs.

Native Desktop Application Development Services: The Tried and Tested Approach

Native desktop apps are designed specifically for a particular operating system, whether it be Windows, macOS, or Linux. These applications are built using the programming languages and tools that are native to the respective platform, such as C# for Windows, Swift for macOS, and C++ for Linux. The primary advantage of this approach is that native apps provide optimal performance, as they can fully leverage the hardware and software capabilities of the target system.

When working with a desktop software development company specializing in native applications, the resulting products are often more responsive, stable, and feature-rich. Native apps also offer better integration with the platform’s ecosystem, allowing for smoother interaction with system features like file management, networking, and security protocols.

However, the downside of native development is that it requires different codebases for each platform. This can be time-consuming and resource-intensive, particularly for businesses that want to target multiple operating systems. Additionally, updates and maintenance must be performed separately for each version, which can further complicate the development process.

Cross-Platform Desktop App Development Services: The Versatile Solution

On the other hand, cross-platform development allows businesses to build one app that works across multiple operating systems. Technologies like Electron, Flutter, and React Native enable developers to write a single codebase that runs on Windows, macOS, and Linux without having to build separate versions for each platform.

The most significant advantage of cross-platform desktop app development services is cost-effectiveness and faster time to market. By using a unified codebase, developers can streamline the process of developing, testing, and deploying applications. This is particularly beneficial for startups and small businesses looking to quickly expand their user base across various platforms without the overhead of maintaining multiple codebases.

However, while cross-platform apps are cost-effective and efficient, they may not deliver the same level of performance as their native counterparts. Although significant advancements in cross-platform technologies have made them more efficient, there can still be compromises when it comes to the responsiveness and feature richness of the application.

Which is Right for You?

When choosing between native and cross-platform desktop app development services, the decision ultimately depends on your business requirements. If you need an app with top-notch performance and platform-specific functionality, working with a desktop app development service that specializes in native applications is your best bet. On the other hand, if your priority is reaching a wider audience quickly with a unified codebase, cross-platform development might be the most suitable option.

Ultimately, both approaches have their merits, and selecting the right one will depend on factors like budget, timeline, target audience, and the complexity of the features you require.

Conclusion

The choice between native and cross-platform desktop app development is not an easy one, but understanding the key differences can help guide your decision. Whether you are considering a desktop software development company for native development or seeking the versatility of cross-platform solutions, it’s important to assess your project’s specific needs. By making the right choice, you can ensure that your desktop app delivers the best possible user experience and meets your business objectives.

Choosing Your Weapon: Electron js vs React Native vs Node.js

Frameworks and runtime environments abound for application developers, and each has advantages of its own. Three popular frameworks are available for creating desktop applications: React Native, Node.js, and Electron.js. Nevertheless, which one is most appropriate for your project? Let us analyze their benefits and drawbacks to assist you in making a decision.

Electron.js: Building Desktop Apps with Web Technologies

Leveraging Web Skills: Using the Electron.js framework, programmers may use web technologies like HTML, CSS, and JavaScript to create desktop applications. For online developers looking to venture into desktop app development without facing a steep learning curve, this is the ideal solution.

Native Look and experience: Because Electron programs have access to native system components and APIs, they have an operating system-integrated experience.

Cross-Platform Compatibility: Electron apps are easily deployable across several platforms with few code changes required to bundle them for Windows, macOS, and Linux.

However, Electron.js has its drawbacks:

Greater Application Size: Compared to native apps, electron apps have larger application files because they come with a web browser engine bundled in.

Performance considerations: Although there has been progress in performance, Electron apps may not always equal native applications in terms of responsiveness.

Increased Maintenance Overhead: Keeping up different codebases for native and web UI features can be more work.

React Native: Building Mobile Apps with Cross-Platform Reach

Useful Codebase: With React Native, developers can build the majority of the logic for their applications in JavaScript, which can be applied to both the iOS and Android platforms. Development time and maintenance costs are decreased as a result.

Native-like Performance: React Native provides a quick and responsive user experience that is akin to native applications by utilizing native user interface elements.

Huge and Active Developer Community: The React Native community is quite active and offers a multitude of resources, including third-party libraries, tutorials, and tools, to make development processes simpler.

However, React Native has limitations:

Learning Curve for Non-React those: React requires some time to become familiar with for those who are not familiar with it.

Restricted Access to Native Features: Some features may offer native UI components, but complete access to native device functionality may need platform-specific code.

Compared to native development experiences alone, debugging problems can occasionally be more complicated.

Node.js: The JavaScript Runtime at the Core

Server-Side Development: Node.js is a runtime environment that makes it simple to develop server-side applications and APIs. It enables JavaScript code to be executed outside of a browser.

Event-Driven Architecture: Node.js's non-blocking, event-driven architecture is perfect for handling real-time applications and microservices.

Large Library Ecosystem: Node Package Manager (npm) provides a vast library of pre-built modules, covering a variety of functionality and speeding up development.

However, Node.js might not be the best choice for

Construction of Desktop Applications: Node.js is not meant to be used for desktop UI application development, while frameworks such as Electron.js use it for backend development.

Resource-Intensive activities: When it comes to compiled languages, Node.js might not be the most effective option for computationally demanding activities.

The Verdict: Choosing the Right Tool for the Job

React Native, Node.js, or Electron.js can be the best choice for your project, depending on its specific requirements.

Desktop Applications: Electron.js is an excellent option if you want to leverage web technologies and achieve cross-platform interoperability.

Mobile Apps: React Native is a fantastic tool for developing reusable and effective mobile apps. The industry standard for developing scalable, event-driven server-side applications is Node.js.

With an understanding of the benefits and drawbacks of each technology, you can make an informed decision that moves your project closer to success.

67 Articles later...

Three and a half years ago I wrote an article which summarized my foray into the world of software blogging, and provided clickable links into each of the thirty three articles I had written up to that point (risebird.tumblr.com/post/115727628135/thirty-three-blog-articles-later). Although my article-writing pace has slowed down somewhat since then, the articles I’ve focused on writing have not lost their thirst for cutting edge developments in the software industry (especially of those in the quickly-evolving front-end space). I have evolved my career since that April 2015 to be sure, and hopefully my writing ability has progressed also; but as always, you will be the judge of that. So without further ado, I give you the clickable summary of my latest thirty four articles, enjoy!

When building a new mobile app you might have asked yourself whether to build a web app, a native app, or perhaps a hybrid (risebird.tumblr.com/post/134179609930/how-should-i-build-my-mobile-app). Of course, nowadays you can even make a “Progressive Web App” that can still work offline (risebird.tumblr.com/post/172163267760/progressive-web-apps)! In any case it is extremely valuable for a web developer to understand how modern browser performance is advanced through the use of parallelism (risebird.tumblr.com/post/177300904440/modern-browser-performance). In fact, GPUs have re-invented data visualization because of it (risebird.tumblr.com/post/136172693860/getting-deeper-into-d3). Combined with the awesome D3 visualization library (risebird.tumblr.com/post/130034738155/the-d3js-visualization-library), we can accomplish a lot nowadays. D3 experts will get deeper into this library (risebird.tumblr.com/post/136172693860/getting-deeper-into-d3) and even explore it to a very detailed level (risebird.tumblr.com/post/167332736675/details-on-d3); however, the real sparks fly when you combine it with React (risebird.tumblr.com/post/147473986500/d3-react-awesome)!

With the UX expectations of users constantly changing, such as those of modern layouts (risebird.tumblr.com/post/124227499425/modern-layouts), new methods of delivering data to the users, such as immersive analytics (risebird.tumblr.com/post/164978764330/immersive-analytics) have been developed. Dealing with the data itself can be tricky enough (risebird.tumblr.com/post/179818036890/dealing-with-data), but you also need an application capable of bringing it to the end user as quickly as possible (risebird.tumblr.com/post/133313428230/modern-js-apps-single-page-vs-isomorphic). Will you create a standard service oriented architecture around Node (risebird.tumblr.com/post/142205462000/node-microservices) and use a popular tool to build your database (risebird.tumblr.com/post/119012149675/popular-databases-in-2015) to achieve this? Or will you perhaps rely completely on other third party providers for data access/storage (risebird.tumblr.com/post/123359620325/the-front-end-is-the-new-back-end)? Don’t forget that there is no such thing as “serverless” (risebird.tumblr.com/post/158339348525/there-is-no-such-thing-as-serverless). No matter what application server you do choose (risebird.tumblr.com/post/140322249595/node-vs-apache-vs-lighttpd-vs-nginx), be sure user access is regulated with JWTs (risebird.tumblr.com/post/139393722945/json-web-tokens), and that your applications are taking advantage of the new features available in HTTP2 (risebird.tumblr.com/post/132841671265/why-you-should-deploy-http-2-immediately). And always unit test your JavaScript with Jest (risebird.tumblr.com/post/163897551825/javascript-unit-testing-with-jest).

In the future, our applications will all be connected throughout the physical world (risebird.tumblr.com/post/137612619330/centralized-iot-development), and even in the present IoT is already impacting modern applications (risebird.tumblr.com/post/127988661815/a-real-world-iot-application). In such a connected world, it pays to understand how the networks and protocols that deliver these electronic messages to and from us operate (risebird.tumblr.com/post/156345541115/the-lte-physical-layer), and how the messages use sensors and actuators to interact with physical environments (risebird.tumblr.com/post/144442019200/fun-with-development-boards). Drones are especially interesting in this context (risebird.tumblr.com/post/117830816210/drones-in-2015). I also thought greatly about how AI can be used to evolve logic on its own (risebird.tumblr.com/post/170245126095/simulating-life-an-ai-experiment), and how abstract syntax trees can go a long way in achieving this (risebird.tumblr.com/post/171045918950/artificial-neural-networks-versus-abstract-syntax). After starting with some basic ideas for this (risebird.tumblr.com/post/174655336230/simulating-life-early-code), I dove into some of the complexities of mutations in directed evolution (risebird.tumblr.com/post/175132399985/simulating-life-mutations).

Finally, I wrote about the power of the emerging blockchain technology (risebird.tumblr.com/post/162633306305/blockchains-the-technological-shift-of-the-decade), the usefulness of using Wikipedia (risebird.tumblr.com/post/129037111590/trust-in-wikipedia), an interactive news map website I built with my father (risebird.tumblr.com/post/161497655355/mapreport-the-dynamic-news-map), and about making music with JavaScript (risebird.tumblr.com/post/166247227950/make-music-with-javascript)!

I hope you’ve had as much fun reading these articles as I’ve had writing them, it will be great to reflect again on these when I write my 100th article sometimes soon :)

One Word: Mobile App Development Company in Zambia

A network connection is typically used by a mobile application to communicate with external computing resources. Mobile application development is the process of developing software applications for portable electronic devices. As a result, creating installable software packages, setting up backend services like data access through an API, and testing the application on the specified target devices are all part of the mobile development process.

Types of mobile apps

· Native Applications: Integrated Development Environments and Languages for Mobile Operating systems like Apple iOS or Google Android are used to create these applications. Although you can personalize essential features with native apps, they can be more expensive than alternative technologies.

· Hybrid apps: These Web applications function much like native ones. Technologies like HTML, JavaScript, and Cascading Style Sheets are used to create them. Hybrid apps can be developed more quickly and more affordably than native apps, but they lack the same feature-richness.

· Progressive Web Apps: A PWA is a website that has the appearance and functionality of a mobile app. These programs were created using Web technologies like Facebook React.

· Encapsulated apps: Running inside of a container app is an encapsulated app. Less experienced developers can quickly create a mobile application with tools like the Microsoft Power App drag-and-drop app creation tool. However, issues could arise due to OS lock-in, lack of isolation from the core OS, and relative youth.

· Frameworks and libraries: You can hasten the creation of a mobile app by using this reuseable code created by someone else.

Mobile App Frontend Development

Your customers will view the mobile app's front end. Mobile frontend development makes use of a wide range of various technologies. Some programs require backends and APIs, while others only require the platform's built-in databases.

Almost any Web programming language can be used to develop the backend of your mobile application. While developing native applications, you can make use of technology-specific resources.

Each programming language offers a unique set of features, depending on the platform you use. You should be able to choose a team that is educated about which key technologies may be employed most effectively by choosing the best programming language.

Mobile App Backend Development

The backend of your mobile app functions very differently from the front end, which is how it generally works. You may think of the backend as an additional application. It is software that operates on distant computers known as servers. It is accessible via API on the Internet. The backend is intended to be utilized by other programs and not by people directly. Its function is to carry out remote operations that, for a variety of reasons, the frontend apps are unable to carry out.

Frontend vs. backend

Frontend development focuses on the visual components of software, websites, and mobile apps while also designing and creating applications. An end user engages with this portion of the software solution.

A typical end-user might never see or utilize the server side of software, a website, or a mobile app because backend development is concentrated on that side of the application. In the form of data, verification, authentication, security, and other services, the backend offers crucial support.

Any app's success and functionality depend on its frontend and backend. They collaborate flawlessly to create a dynamic mobile app and enable users to do their tasks.

Android App Development

A mobile, multitasking operating system is utilized in TVs, readers, consoles, smartphones, tablets, and even home robots. Android Inc. created the Linux-based operating system, which Google later bought and popularized. Modern smartphones and tablets can be thought of as pocket mini-computers because of this operating system.

Less than an hour is sufficient for getting to know Android, which is a very flexible and user-friendly system. Due to the abundance of pertinent programs, any user can simply configure OS settings. The appearance, icons, or ringtone may all be changed beyond recognition; simply visit the Google Play Store, download the appropriate software, and rapidly customize everything to your preferences.

IOS app development

The process of creating mobile applications for Apple products, such as the iPhone, iPad, and iPod Touch, is known as iOS application development. Swift or Objective-C are used to create the software, which is then posted to the App Store for people to download.

You might be wary about developing iOS apps if you work as a mobile app developer. For instance, a Mac computer is a must for developers and is typically more expensive than Windows-based PCs. Your software must also pass a rigorous quality assessment procedure after it has finished development before being made available through the App Store.

Windows App Development

The majority of desktop software is native, meaning it was created specifically for a given operating system. To name a few more well-known frameworks, programmers can also create cross-platform desktop applications by utilizing desktop development tools. Once more, creating mobile apps is comparable to this.

Desktop applications must be downloaded to your computer in order to function because they don't need an Internet connection. Additionally, desktop programs can get at the device drivers on your computer. You might not be aware that the device's drivers can only be accessed by software that has been downloaded to your computer. For instance, the only reason you can play sound from a web app is if it is running on your preferred desktop browser.

Conclusion

The topic of developing mobile apps is complex. The user experience must always come first when developing apps, whether they are cross-platform or native. Your app's functionality must match its primary use case, and the interactive components must be easy to use.

Enhance eCommerce with Innovative Mobile Applications

May I develop my eCommerce application with a Progressive Web App?

The topic

PWA

(Progressive Web App-Definition see box) is currently being widely propagated, especially within eCommerce.

Rightly so, is this not a new mouthpiece to make a huge fuss?

Here, I would like to clarify briefly what a PWA is, what advantages it can have for

eCommerce

businesses, and what attention should be paid to when approaching the topic. To put it briefly, what is a PWA?

As the name suggests, it's basically an application, i.e. a web-based software application (as opposed to a native Windows, Android, or iOS application). One can best imagine progressive as "growing with the game. So that it evolves, as we know from before, from a regular website to a modern web application, which hardly differs from a native one. So it does so practically automatically, depending on the environment (browser) it encounters. Why would an operator choose a Progressive Web App (PWA) for E-Commerce?

Any owner of an eCommerce platform will probably want to increase his turnover. In my opinion, the eCommerce Progressive Web App (PWA) has three key advantages over a conventional website:

1. Quicker2. More picturesque3. LOWER Faster, because much of the Innovative Web App is running in the browser of the user (and not on the server of the provider), it can handle data and loads more easily with smaller numbers. But due to the app components, the initial load is slightly larger, many server requests can be saved afterward. It means that while the classic website needs to load more and more content from the server, the PWA has to load only the most important data ( e.g. only images and details of the product, but not the entire software code). Louder, as the Progressive Web App enables eCommerce owners to use different methods to put the product to the attention of the customer:

Homescreen: As with regular devices, PWA can be put on the home screen. They run fullscreen if you start them from there, i.e. the customer stays in the context of the application and can not turn "quickly" to the competitor

· Push Alerts: A PWA can also submit Apps-like push notifications. This gives you the opportunity to draw the attention of customers specifically to promotions etc.

I missed one highly important argument: Google. Google loves fast websites and is pushing the PWA topic. Many SEO experts believe a page that completely meets a PWA 's requirements would push Google's rankings upwards. Unfortunately, as normal with SEO, there are no absolute truths and so there are other experts who say that the so-called Server Side Rendering (see box) is important for optimum Google results – so, in theory, a traditional, old, static website. That might be the best way, it's undisputed it's heading in the direction of PWA. And as I'll explain below, Progressive Web App and Server Side Rendering needn't contradict one another. Function Comparison: Progressive Web App vs. Native App

APP VS NATIVE PWA

Of course, whether a native app or a PWA is recommended depends always on the intended use. But what impressively illustrates the comparison is how many areas the "Web Native App" – i.e. the PWA – has already opened up to the Native App, and how many benefits it has achieved.

From our many years of experience in eCommerce, we know that it is becoming increasingly important to be able to react quickly to market demands and to quickly try out ideas.

There are solutions for the PWA in the form of Frontend Management Platforms that allow the business managers to make simple changes and quick tests. There is usually only a tedious way to get the Native App.

Why Can Smart Mobile Applications Easily Use Electronic Commerce Quite individual: Do it all yourselfFast and dirty: The PWA ProxyA Frontend-as-a-Service modular architecture Do things your own way:

Companies with software DNA in particular but even companies with a broad internal IT department prefer to develop and run their eCommerce entirely on their own. It makes even junior programmers happy-they can actually do some basic work. Most companies, however, underestimate the challenge. After all, it's not all about providing an outstanding customer experience; the entire development process must be managed, stable, automatically scalable hosting must be maintained, and – most importantly – the online marketing team must be able to make regular changes without having to rely on programmers. Only thus can they keep up with the strong competition. Fast and dirty:

If you have a current, modern eCommerce platform, just because new technology is evolving, you don't want to throw away anything and create a new one. Therefore, there are some providers on the market that are practically acting as a proxy in front of an existing shop and thus promising to create an excellent mobile customer experience. Frontend:

For two years now the trend toward an API-first architecture in eCommerce has gained ground. At the same time, Frontend-as-a-Service has been developed by other firms. Such providers concentrate on excellent user experience on all screens and have a Revolutionary Web App for mobile devices in particular. As in other situations, it is important that the people in the departments responsible for eCommerce 's success in day-to-day business will function autonomously from the tools of developers. The Frontend Management Platforms include an easy-to-use editor that helps web administrators and advertisers to execute their ideas and promotions as quickly as a homepage creator does. PROGRESSIVE SERVER SIDE VS. Making Mobile APP

When you believe in Google's own Lighthouse Score, when you have a clean PWA implementation, you don't have to think about Server Side Rendering (SSR). What is the point?

In short, server-side rendering is the standard form of producing a web application. On the server, all of the critical content is measured and transmitted "full" to the browser of the client. Every page change, every user interaction first goes to the server which calculates and delivers the corresponding page to the browser. This is a highly tried and tested technology that needs very little resources on the part of the customer and makes no demands on the hardware of the customer. And not just to the customer but to the search engines as well.

As this is a client-like behavior Google can index a modern PWA and even "rewards," this mobile-friendly technology, in the opinion of many "SEO experts."

Modern approaches most often provide a hybrid approach: the content is provided to search engines as SSR and to actual customers as PWA. Testing-Learning-Improving:

Anyone who today wants to run eCommerce successfully has to hold their own against the major players on the market. To put it plainly, with very little resources, each has to find his own way to sneak up on the major players. A lucrative market, ideal pricing, creative concepts-these are only a few of the opportunities.

If your customers access your offer from mobile devices, you should be concerned with the subject of the Progressive Web App, definitely – but not at any price. The PWA must fit into the overall plan, from my point of view. In my experience, agility is an important factor for success today – regardless of any of the aforementioned forms you want to be successful in eCommerce. You have to be able to change your range, again and again, your pricing and your overall bid.

The credo is "Research-learning-improving." If you don't have a front-end development team of 100 people (who still also have free resources), this might be a subject for you. One support can be a so-called frontend management tool that makes it easy for online editors to make changes based on existing components. DL; RD

PWA is more than just another roost-run. Yet the evolution must continue all the time. So don't make a fast fix, but use a modular architecture with an API-first eCommerce framework and a Frontend-as-a-Service that helps the business team to do the day-to-day business without relying on a single editor to code.

Miroir pocket pico projectors Review

As known, projectors traditionally used powerful lamps as a light source. Unfortunately, they have a limited resource, high cost and high heat dissipation. As a result, such models require a large internal volume for heat dissipation and a powerful cooling system with a high noise level. But successful semiconductor light sources development has radically changed the situation. Increasing their radiation power and lifetime allowed engineers to use LEDs as a light source in the projectors. As known, LEDs and laser LEDs practically do not heat up, and their service life reaches 30,000 hours, which corresponds to more than 10 years of active use. Of course, any modern electronics morally becomes obsolete over such a period. As a result, new compact light sources provoked the appearance of a whole segment of LED projectors. Of course, compactness has become one of the main directions of their improvement. Such models are often called pico projectors. But many companies often use the terms mini, pocket or portable.

Introduction

The story of their appearance on the market begins in 2003, when the Israeli Explay company announced the development of mini projector. Already in October 2006, the company publicly demonstrated the first Explay Nano Projector. The name pico-projector first appeared in November 2008 during the Optoma advertising campaign, which introduced the PK101 pico projector. This iPod model supported HVGA resolution, screen sizes up to 66 inches diagonally and Lumen Output up to 9 ANSI Lm. Many consumers enthusiastically reacted to the new gadget. Of course, the high demand did not leave the companies indifferent and they actively engaged in the competition in the new segment. As a consequence, today many companies, including Sony, Optoma, AAXA Technologies Inc., Rif6, LLC, Anker, Apeman International Co, etc offer pico models. Of course, Miroir was no exception, actively involved in this process. In addition, the modern market offers smartphones with projector functions.

Miroir projectors

As known, Miroir USA, LLC has over 15 years experience in the projection display technology in close partnership with Texas Instruments. Ultra portable projectors is one of the main areas of the company. Today Miroir USA, LLC ranks among the leaders of this segment, using its own manufacturing facility in Shenzhen, China and sales offices in China, USA and United Kingdom. Its modern models use а Texas Instruments 720p DMD chip and new IntelliBright technology to dynamically adjust the projector’s brightness range for each pixel, based on the room’s ambient light. Probably, Miroir Pocket MP60 can be considered the first popular pico-projector from this company. The company produced it from September 2014 to May 2018. At a cost of $ 300, the projector has brightness of 85 ANSI lm, contrast of 1,000: 1 (full on / off) and 854 x 480 resolution. Its size and weight (2 cm x 10 cm x 10 cm and 0.44 lbs) fully corresponds to the Pocket class. Throw Ratio of 1.66: 1 (D: W) provides the optimum brightness (recommended image brightness for rooms with low ambient light) for 32” diagonal screen at a distance of 72” (1.17 m) from the screen.

Miroir projectors 2015

But already in 2015, the company introduced two new models in this segment. The Miroir HD Projector MP150A first appeared in June 2015. The projector costs only $ 225, but provides a brightness of 200 ANSI lm, contrast of 400: 1 (full on / off) and 1280 x 720 resolution. Throw Ratio of 1.66: 1 (D: W) provides optimum brightness for a 50” diagonal screen at a distance of projector lens 72” (1.82 m) from the screen. In addition, the model provides Vertical Digital Keystone and has 1.0 W × 2 speakers. Unfortunately, the dimensions and weight of the model reach 3 cm x 8 cm x 13 cm and 0.66 lbs, respectively. Probably, it can be positioned as a mini-model, although this classification is rather arbitrary. It still successfully competes in the market and is available on Amazon. Already in September, the company introduced the more compact Micro Pocket MP30 with dimensions and weight of only 1 cm x 10 cm x 8 cm and 0.3 lbs, respectively. Despite almost the same price, their specs are significantly different. At a price of $ 200, this projector provides brightness of only 15 ANSI lm and only supports 640 x 360 resolution, but its contrast reaches 1,100: 1 (full on / off). Unfortunately, the projector has only one 0.8 W mono speaker and does not support Digital Keystone. This model also successfully competed in the market, but the company stopped its production in February 2018.

Miroir projectors 2016

In January, October and December 2016, Miroir introduced the Micro Projector MP60W, Miroir Smart Tilt Projector M200A and Miroir HD Projector MP160. In fact, the MP60W has become a white version of the MP60 with similar specs. Today its street price is only $ 150. Miroir Smart Tilt Projector M200A uses Android OS with native apps available and has wireless and HDMI inputs. Its dimensions and weight slightly exceed MP30 (2 cm x 14 cm x 8 cm vs 1 cm x 10 cm x 8 cm and 0.66 lbs vs 0.3 lbs). The projector provides brightness of 200 ANSI lm at 854 x 480 resolution. But its contrast reaches only 400: 1 (full on / off). In addition, the projector has Vertical Digital Keystone option and 8G built-in memory, but only one 1.0 W mono speaker. Its Throw Ratio of 1.66: 1 (D: W) provides a 50” diagonal screen at a distance of 57” (1.44 m) from the screen. Today, the street price of this model does not exceed $ 225. Miroir HD Projector MP160 is not a smart model. Unlike the M200A, it supports 1280 x 720 resolution, with the same brightness and contrast. In addition, the model provides auto ± 40 ° Vertical Keystone Adjustment and has 1.0 W × 2 mono speakers. Unfortunately, it's less compact. Its dimensions and weight reach 3 cm x 11 cm x 11 cm and 0.8 lbs, respectively. Its Throw Ratio of 1.66: 1 (D: W) provides a 50” diagonal screen at a distance of 72” (1.83 m) from the screen. Today, the company sells this model for $ 210.

Miroir M55 and M45 projectors

In 2017, the company introduced five pico-models, including the Miroir M300A (March), M55 and HD M220 (August), M45 and HD Mini Tilt M175 (December). Unfortunately, the brightness of the low-power M45 and M55 reaches only 15 Lm. According to the company, they provide a 50” diagonal screen. But the projection calculator from the authoritative https://www.projectorcentral.com shows only 13” of Estimated Image Brightness (Throw Distance of 0.35 meters) at Recommended image brightness for rooms with low ambient light (120 nits). This information is more accurate. As known, the image quality, including clarity and color saturation, directly depends on the ambient light level and is inversely proportional to the screen size. In turn, the requirements for the ambient light level directly depends on the brightness. Therefore, projectors with low Lumen Output or brightness (several tens of ANSI lm) cannot provide high projection quality for a sufficiently large screen size (for example, 50” and above). In addition, they require complete dimming. Otherwise, image will be too dim. Of course, light-absorbing panels on the walls and a special screen with a high Screen Gain partially solve this problem. Unfortunately, companies usually do not specify this aspect in the specification for the model, indicating the maximum possible screen size. The contrast and resolution of these models reaches 1,000: 1 and 640 x 360. Size and weight do not exceed 2 cm x 12 cm x 8 cm and 0.22 lbs, which fully corresponds to the pico classification. Their Throw Ratio is 1.20: 1 (D: W). Despite the almost identical specs, the cost of the models is significantly different and amounts to $ 150 (M55) vs $ 68 (M45).

Miroir Smart HD M300A

Of course, Miroir Smart HD M300A belongs to a higher class. It provides brightness of 400 ANSI lm and 1280 x 720 native resolution. Unfortunately, the company does not provide contrast data. Its Throw Ratio of 1.12: 1 (D: W) provides 71" @ 69 inch for optimal 111 nits at Screen Gain of 1.2. This smart projector works with streaming apps, select content from USB sources, easily connects using included HDMI cable, and has the ability to share select content wirelessly. Model uses Android 4.4 and Bluetooth. In addition, the projector has HDMI and Wireless Input, 5 GB built-in memory and two 2W speakers. Moreover, the model supports Autofocus and Keystone Correction. But its dimensions and weight reach 3 cm x 15 cm x 10 cm (HxWxD) and 0.88 Lbs. Accordingly, its classification as a mini projector seems more reasonable. Today the price of this model reaches $ 487. Many reputable resources include the Miroir HD M300A in the top list of the best Smart pico projectors. The video at the end illustrates the capabilities of this projector.

Miroir HD M220 and M175 projectors

Specs of Miroir HD Pro Projector M220 almost completely coincide with the previous model. The M220 is not a Smart model, its contrast does not exceed 400: 1 (full on / off), and the weight reaches 1.1 Lbs. But its price does not exceed $ 400. Miroir HD Mini Tilt Projector M175 also does not support Smart features. Its brightness reaches only 200 Lumens at a resolution of 1280 x 720. The size and weight are identical to the M300A (3 cm x 15 cm x 10 cm and 0.88 Lbs). This model uses a hinged case with 90 degree tilt function and auto vertical keystone correction (± 40 °). In addition, the projector has 2.0 W × 2 speakers, USB charging out port and supports up to 80” screen in semi-dark spaces. Like the M220, it costs $ 400.

Miroir Ultra Pro Projector M631

The Miroir Ultra Pro Projector M631 appeared in January 2019 and belongs to a higher class. It's a very portable, native-1080p projector with brightness of 700 ANSI lm, contrast of 1,000:1 (full on/off), two HDMI ports and a USB C port. Its weight and dimensions do not exceed 1.5 x 9.5 x 5.4 in and 1.98 lbs. But these specs are more suited to mini-projectors than pico. As known, Miroir positions this model as an accessory for the iPhone, iPad, MacBook and Apple TV. But the USB C port provides connection to almost any modern device. Its advantages include a 1080p native resolution with support for 4K input at up to 30 Hz, screen size from 20 to 120 inches diagonally, motorized focus and auto-keystone correction ± 40°, ease of use (controls only for focus, volume, source and power level), two built-in 3-watt speakers, USB charging port, inverting function for a ceiling mount, two HDMI ports and one USB-C. However, some experts consider a limited set of settings a disadvantage. Unfortunately, the price of this model reaches $ 650, which significantly exceeds the cost of other models under this brand.

Conclusion

Thus, today the company offers a full lineup of mini projectors, including Smart models, with brightness from 15 to 700 ANSI Lm, resolution from 640 x 360 to HD and priced from $ 68 to $ 650. Of course, such a wide range greatly simplifies the selection of the optimal model. Read the full article

Web Development 2020 - Coding Tools You Must Have!

With the starting of 2020, there's a lot of hype to hear on social media about upcoming technologies and up-gradation in the existing ones. Although you must emphasize on 1 thing only - don't feel daunted or let yourself get overwhelmed. After a lot of brainstorming analysis we've summarized a competitive insight for your convenience. But remember that we are not trying to overwhelm you a lot of available technologies out there. When you get to know something you tend to learn research what it is. However, you must only choose if you want to learn everything in it.

Now the primitive goal of this article is to give you brief about with mainstream web development tools available for web developers:

Let’s start by deciding what you want to do? Do you want to work in an organization? Or work as free consultant? Want to develop a product of your own or work as a freelancer?

Tool 1: The Necessities

You don't need a fancy computer for web development. We are not into computer game development or something like that, so any mid-range laptop or desktop will suffice. Web developers can use Windows 10, macOS, and Linux for media servers. For editing VS Code is sufficient whereas Chrome and its built-in dev tools for browser-based debugging. Firefox is also a viable alternative which has come a long way. Just start with standard HTML and CSS, with the learning of newer CSS tools like Grid and Flexbox. It’s also recommended to have a deep understanding of responsive web designing since its necessary that every created project must have good look and complete usability on every device. Don't rely much on CSS frameworks like Bootstrap; instead, build your own modular CSS components that can be used again throughout the project. Tailwind is another framework that's a bit different from other existing CSS frameworks. Majorly focused on "utility classes" which easily to combine for getting a desired design. In easy words get good with JavaScript’s.

Tool 2: Practical Learning

Even the best developers in web development company in UAE emphasizes the need for practical learning, which is a good way to learn faster without getting embroil in tools. Learning DevOps and AWS is not required for a developing small website. Managed hosting like Hostgator or InMotion is appropriate for deploying a website in a browser. For upcoming developers, it’s important to work like a basic front end developer which helps develop websites of local businesses like a freelancer. It’s not important to use a front end framework since template rendering can be done without using a front end framework. Those ready for aggressive front end frameworks can explore React, Vue, and Angular and figure out which one is the best. Growing popularity of server-side rendering tools like Next.js (for React) and Nuxt.js ( Vue option) has made the creation of complicated routing files unnecessary. Instead, you can just put the files in the directory you want them to be in.

Tool 3: Back End/Front End Development & Web Servers

Node.js should be preferred for server-side development due to its speed and availability of JavaScript for both front and back end. We would also recommend the “LearningExpress” Library since it's the most popular and gives you ample freedom to craft things in your desired ways. Python has two awesome frameworks whereas Django is a full-featured framework and Flask is minimalistic. PHP is a great language with simplicity to deploy anywhere and a great platform for freelancers who requires to get stuff out quickly. Also if you look at Laravel code it's very elegant.

GraphQL is an alternative to REST for APIs, that's big enough to stay and more than just a trend. Further moving to CMS's (Content Management Systems) as they get to evolve into an option where they can be used as back end for coding your front end. Its useful for freelancer to create their blog posts and similar stuff using WordPress, which is still very popular. For web servers, NGINX is less complicated than Apache and can be used extensively at freeCodeCamp.

For mobile app development, we strongly recommend the Flutter framework, using Dart, which is a more obscure language and positioned between Java and JavaScript. Another good choice for mobile app development is React Native, which can be easily understood if you know React. Here Progressive Web Apps is a considerable option because of the relative ease in development process and attractive user experience. Similarly for building desktop applications using JavaScript, must go for Electron which has been used to create functional desktop apps like VS Code and Discord.

Tool 4: Machine Learning and Web Assembly

A trend that's been here to stay long is "Machine Learning". And yes, it can be used for machine learning in JavaScript’s too. Python is most suitable for Machine Learning and if you are working on JavaScript then TensorFlow.js is appropriate, whereas Brain.js is good for creating neural networks. The concept of Web Assembly is in the early stages and expected to grow more this year. Till now, JavaScripts has been used to manipulate DOM and run calculations in web pages but it has some limitations in terms of speed. Languages like C or C++ are much faster than JavaScript. Web Assembly is a low-level byte code that’s efficient, fast and easy to be executed by any browser. Rust is a much easier language option that can be used with WebAssembly (apart from C and C++). But it's important to note that WebAssembly requires learning of JavaScript’s which allows utilization of really fast low-level languages like C++ in web apps, but with lot more capabilities - like video editing and next-level video games tools right in the browser.

Conclusion

The more you learn, the easier it will become to adapt and fit all the mentioned technologies together. However, it’s not something to get overwhelmed. Just take one step at a time and continue doing some research to figure out the necessary steps.

Top 10 Cross System App Development Tools

Do I desire a Macintosh personal computer to make iPhone apps? This coincided with Apple’s introduction of the second-generation iPhone 3G which reinforced mobile apps. In comparison with cross-platform alternatives, local mobile applications tend to be more productive and steady working. And beyond the old web programs vs. native software question, a hybrid mobile iphone app would be the right answer freelance designers for you, depending on the needs you have and source constraints.

IOS users spend additional money on in-app buys than Android users. My advice to mobile software platforms is adopt the inevitable Automation, accessibility, useful, localization,, performance security and usability tests are a few of the screening services offered for mobile and web applications. Flutter works on the one codebase feature this means to make Android and iOS apps, coders won’t have to set-up separate codes.

Fabricating efficient design and interface that may be quickly deployed on the iOS system. App Inventor has 3.3 million new users from 185 countries presently, who have done producing 8.9 million apps. We’ve catered our iOS iphone app development services in 30+ countries while focusing on various customer iOS development requirements. NativeScript isn’t the only real cross-platform mobile development platform away there that works together with common Web technology or even popular Web frameworks.

This approach provides versatility to create a cross-platform request in a totally custom manner like the net wrapper option provides, but at exactly the same time offering easy performance. This period is the most unrewarded and overlooked side of the application form development, but comes first in the arena when the software misbehaves. Let’s take a look what toolkit you will need to develop iOS software – it’ll offer you a more detailed eyesight.

Moreover, there’re a whole lot of alternative party answers to create iOS programs where you wouldn’t desire a Mac by any means. But also for the gomobile tool to work, we first need to set up the Android NDK (Local Development Package). Surf and explore software for your iPad, iPhone, ipod device, or Apple Watch in the App Store. Building an iOS software hasn’t been simple with the sophisticated business logic that must use in the real-world development process.

If you’re looking for iOS Apps Development companies to personalize your iPhone software into iPad, e mail us with your concerns and we will be ready to provide you the best APP Development services. Apple users will purchase apps, except in a single category – power apps. In addition, undertaking several testing on real cellular devices will understand the app’s conversation flow and find possible bugs.

While searching for React Local developers, it’s also advisable to be looking for anyone who has experience in local development. Java programs on the Macintosh personal computer are an awful example, but recently there are several goofy half-baked interfaces built on Electron or Telephone Gap can cause super-irritating alien seeming apps. Peerbits developed an operating iOS iphone app for a leasing company with top-class” visual UI. Communication was fluid, deadlines were achieved, and the deliverables were quality.

Reach an evergrowing audience of folks using cell phones and tablets by displaying your advertisings in mobile apps. In this specific article, we will give attention to understanding this code along with some main principles of Flutter Development. Users acquainted with Yahoo Docs, Microsoft Excel, and other spreadsheet tools enthusiastic about easily setting up a mobile application.

Clearbridge Mobile is a high iOS iphone app development company, providing flagship iOS programs for clients including Gannett, USA Today, Enercare and even more. A tech startup veteran was focusing on a fresh fanfare software company and sought to start out with a local mobile app. To the professionals we can feature an iphone app store much bigger capacity to attain out software users, leveraging the trust, set up by a firm that operates an iphone app store, as well as programs purchasing transactions managing takes place with an application store area.

Introduced in 2014, Swift has already been the language of preference for producing iOS and Operating-system X software and services. React Local provides development tools for debugging and request packaging, which will save you time. On the way, we’ll discover that from a higher level, the development process is comparable for both systems. Used mainly to construct applications for iOS, Macintosh, Apple Television set, and Apple Watch, the words has been quickly followed by developers in the iOS community.

Android programs are developed using Java and Kotlin. It’s likely that, you agile development will see a post on the Apple development forum in which a friendly seasoned creator has clarified their plea. Explore and find out common tools, technology, user interface elements, and design habits used to create iOS apps. IP Ownership: We stick to strict guidelines laid right here the NDA and agreement to protect the foundation code in our client’s iOS app.

It’s worth taking into consideration Flutter, particularly if you want an iphone app for iOS and Android. You will monetize your mobile programs by integrating in software acquisitions and advertising. We carefully plan the introduction of the program of i phone and ipad device apps. Eventually, iPhone owners received used to programs charging only $1 or $2.

new engine to perform the Flutter code on, and enough local code to find the Flutter platform working on Android and iOS. Ignazio Calò is a Software Designer with an intensive experience in producing solutions both on the backend and mobile area. Code with Chris – Steps to make iPhone Apps WITHOUT Development Experience – multi-part group of articles on iPhone and iPad software development targeted at people who have no coding experience.

Sans the business sector, Quytech has enthusiastic give attention to augmented reality structured mobile programs and proper mobile consulting services which gives business owners a definite idea about the marketplace competition and development strategy.

Developing modern offline apps with ReactJS, Redux and Electron – Part 4 – Electron

The last part of this series showed the beautiful interplay of React and Redux. In this part however we are going to take a rough look at a technology called Electron. One essential technology in our recent projects. Electron is vastly different from the previous two parts of this blog series. React and Redux are solely used to implement the application logic. Electron on the other hand is used to implement both structure and application logic to create real cross platform desktop apps. It is a wrapper which contains a chromium browser in an NodeJS environment. This technology enables the combination of pure web frontend technologies and additionally gives your application full access to the underlying operating system via NodeJS. In the following chapters we will introduce the basic concepts using a simple Electron app and show how this technology solves the everlasting single threaded obstacle of non-responsive JavaScript applications.

Introduction

ReactJS

ReactJS + Redux

Electron framework

ES5 vs. ES6 vs. TypeScript

WebPack

Build, test and release process

The Core Parts

An Electron app consists of a few main parts. The basic concept is that you have two or more concurrently running processes. First you have the main process of your application. In this process you have access to NodeJS and thus all your operating system’s power and access to a huge distinct subset of the Electron API. Furthermore the main process creates browser windows. They have one or more render processes and share an important property with your normal browser. These processes are contained in a sandbox. That is because these processes are responsible for rendering the DOM of our web app. Render processes have access to the NodeJS API and a distinct subset of the Electron API, but not to the operating system.

A few functionalities of Electron can even be used in both the main and a render processes. By default JavaScript processes in NodeJS and Chromium are single threaded and therefore still limited, even if both processes are operating system level processes.

OS Integration

Because of Electron’s nature to be a JavaScript technology the final app can be deployed to common desktop operating systems like Windows, MacOS and Linux in 32 and 64-bit versions. To do that you can use the electron-packager which is developed by the community. The packager creates installers for various operating systems which make it easy to deploy the Electron apps in enterprise environments. Further Electron provides essential OS integration on its own. Menu bars, OS level notifications, file dialogs and many other features for nearly all operating systems.

In our projects we used the file dialog to import files from the file system. The allowed properties depend on the operating system. Please checkout the API for more details [DIALOG].

const {dialog} = require('electron'); const properties = ['openFile', 'openDirectory’]; dialog.showOpenDialog({ properties });

We also created custom Electron menu bars for production and development mode. During development we could toggle the developer tools from chromium. For production you can remove that feature from the final Electron app.

To see a full list of all native Electron features go to [ELECTRON].

IPC Communication

In the previous section we talked about the awesome OS integration of Electron. But how can we harness the full potential of our operating system and backend languages like NodeJS to unleash the power of JavaScript? We can do this with the built in inter-process-communication in Electron. The modules that handle that communication, the ipcMain and ipcRenderer, are part of Electrons core. ipcMain enables communication from the main process to the render processes. The ipcRenderer handles the opposite direction from render to main.

“The ipcRenderer module is an instance of the EventEmitter class. It provides a few methods so you can send synchronous and asynchronous messages from the render process (web page) to the main process. You can also receive replies from the main process.” [IPCRENDERER]

In the following example we register an Event Listener with ipcMain process using the channel name LOAD_FILE_WITH_PATH. Once the Event Listener finished we send an event back to the React app. Depending on the result, we add a “success” or “error” to the channel name. This allows us to operate differently with the response inside React [IPCMAIN].

In the React app we use the ipcRenderer.send to send messages asynchronously to the Event Listener, using the identical channel name. To send messages synchronously use ipcRenderer.sendSync. After that we add a one time listener function for the event using ipc.once. To distinguish IPC calls we add a unique uuid to the Channel name [IPCRENDERER].

electron.js

fileService.js

To debug the IPC communication between your React application and Electron you need to install the Electron DevTools Extension.

npm install --save-dev devtron

Afterwards run the following command from the console tab of your application. This will add another tab with the Devtron tools.

require('devtron').install()

Under the Devtron tab you get all kinds of details about your Electron application. Devtron displays all default event listeners from Electron as well as your own custom listeners. Under the IPC link you can record all IPC calls from your application. The Lint tab allows you to do Lint checks and the Accessibility tab checks your web application against the Accessible Rich Internet Applications Suite (ARIA) standard.

Here is an example what the IPC communication in our project looks like.

Remember that we claimed that Electron is the end of the everlasting single threaded obstacle? Using IPC we can move CPU intensive work to Electron and outsource these tasks using electron-remote. With one single line we can create a task pool that will actually create a new browser window in the background and execute our code (electronFileService.js) in a separate OS process / browser window. Here is an example how to setup the task pool for the file service.

const { requireTaskPool } = require('electron-remote');

const fileService = requireTaskPool(require.resolve('./electronFileService'));

Offline and Storage

When developing an offline desktop application with Electron you have several options on where to store and read data from.

Option 1: Electron / NodeJS

In Electron you can execute NodeJS commands. Therefore you can use almost any module from npmjs.org to read and store data on your local operating system. We recommend this option, when you need to persist and process a lot of data.

SQLite3 (relational database)[SQLITE]

MongoDB (document database)[MONGODB]

Neo4J (graph database)[NEO4J]

Option 2: React & Redux / Web Browser

In the second option we persist and process data inside the browse. Modern browsers offer a range of API’s that allow for persisting browser data, i.e. LocalStorage, IndexedDB, SessionStorage, WebSQL and Cookies. We recommend this approach for small datasets that need to be persisted locally. This can be done with any web technology. In our case the React web application uses Redux as a store for the application state. You can use the redux-persist module to automatically persist the Redux store to the IndexedDB or LocalStorage. In case your web app crashes or you restart the browser, you can configure redux-persist [REDUXP] to automatically rehydrate the Redux Store.

Modern browsers support service worker API to span threads for processing data. If there is information that you need to persist and reuse across restarts, service workers have access to the various browser storage technologies.

Option 3: Combination of Option 1 and 2

There might be times when your desktop client will be online and can retrieve data from a backend server. With our proposed stack you have the full freedom of choosing how to access the backend services. You can either call the backend services via the web application layer (i.e. React WebApp) or you can use the Electron / NodeJS layer. Which way you choose is up to you and might depend on security restrictions or the existence of NodeJS modules you can reuse or other reasons.

Summary

Electron is an extremely powerful technology, which enables you and your team to create beautiful, responsive, OS independent and maintainable desktop applications. Because there is so much more to Electron we highly recommend reading http://ift.tt/2yewDiz for the parts that you are interested in or need in your projects. In conclusion just keep tuned for our next article.
