The Impact of IoT on Mobile App Development
The Internet of Things (IoT) is increasingly becoming an indispensable aspect of our lives, continuously contributing to our day-to-day experiences in myriad ways, with or without our knowledge. Typical IoT applications include drones, smart cars, smartwatches, human tissue appliances, and the smart home sector especially incorporates multiple devices and technologies to improve our lives. It is also pertinent to note that all these technologies require a mobile application to leverage the network. With the continuous developments in IoT technology combined with the increased demand for connected devices, the cost involved in developing and maintaining such networks has decreased. A competent plays an important role by constantly pushing the boundaries of what this technology can offer to the masses. How can the increased integration of IoT into mobile applications bring change? The flow of information is two way – while the data and notifications from all the connected devices are collected in a smartphone app, the very same app can also help users control connected devices such as air conditioners, HVAC systems, television sets, lights, etc., even when the users are away from home, i.e., control the home appliances remotely. It lets you control different features of numerous gadgets and appliances depending on how it is designed and the purpose that it was built for. These purpose-built apps are multidimensional and may include numerous features such as information on components (performance, stability etc.), analytics, as well as two-way communications with sensors embedded within appliances. With such diverse and sophisticated features, IoT app development is significantly more arduous as compared to regular app development. Here are a few aspects to note...

Secure Azure AD User File Upload with Azure AD Storage and ASP.NET Core
This post shows how files can be uploaded to Azure blob storage using ASP.NET Core in a secure way using OAuth and Open ID Connect. Azure AD is used to authenticate the users. The uploaded file descriptions are saved to an SQL database using EF Core so that listing or searching files can be implemented easily. Azure AD user accounts are used to authorize the user uploads and downloads to the Azure storage container. A user access token is used to access the Azure storage container and so each user, or group which the user is assigned to, muss have the correct role to access the files. This makes it possible to implement authorization for the users with Azure roles and role assignments. Code: https://github.com/damienbod/AspNetCoreAzureAdAzureStorage Creating the Azure AD Blob Storage and Container An Azure storage was created in Azure. The Azure storage requires role assignments for the application users or the groups which user this. Add new role assignments for the admin user, yourself and all the users or groups that will upload or download blobs (files) to the storage container. The role “Storage Blob Data Contributor” is used for what we require. You must create a new container in the Azure storage and set the Authentication method to Azure AD User Account. In this mode, the Azure AD user access tokens are used to access the container. If you do not have the rights for this, assign yourself the correct role in the parent Azure storage. The uploaded and downloaded files are for private access only. We do not want a public URL which can be used...

Single Responsibility and Open-Closed Principle Single responsibility means, each class should only do one thing. One of the reasons why each class should have single responsibility is because a class can be changed by more than one member of the group for different reasons. If a class has many responsibilities, the more often the class will be modified then. This can cause module incompatibility and the possibility of conflicts when the code is merged will also be higher. Secondly, open-closed principle means, we should make our class open to extension and closed to modification. In other words, if we want to add functionality, we just need to add new lines of code without interfering the existing code. The goal is the same with the previous principle, which is to minimize the risk of generating errors from editing existing code. Those principles are two of five of the well-known object-oriented programming principles called SOLID principles: Single responsibility, Open-closed, Liskov substitution, Interface segregation, and Dependency inversion. For more details on the other principles, you can search the internet for yourself. More Files, More Commits Working in a team is closely related to using a version control system like Git. One thing that complicates the work the most is the existence of conflicts in certain files caused by different versions of changes from different team members. A possible solution is to create separate files for each different class (or function related to each other). This aims to minimize the possibility of conflicts in files that are being edited by more than one programmer at the same time. Imagine if there is a...

5 Reasons to Choose Flutter for Mobile App Development
Over the last decade or so, mobile app development has seen a continuous influx of new ideas that has given rise to multiple opportunities and possibilities. Different technologies and frameworks have peaked at various times and have seen extensive acceptance for multiple reasons, which have then been replaced by other better technologies overnight – such is the pace at which this field has soared. Developers are constantly on the lookout for the latest tools and frameworks that can enable them to create robust solutions to everyday problems. Flutter, developed and introduced to the world of custom mobile app development by Google, has invariably found itself in the spotlight due to its ease of use and exceptional features. While the backing of a behemoth such as Google does have its advantages, the reasons for the popularity of Flutter – which is now usually the first choice for cross-platform app development – mainly revolve around providing the best features for , which previously required a lot of effort along with issues related to performance and maintenance. With the advent of Flutter, developers can now add native capabilities to cross platform applications more easily, while also providing multiple support options along with a remarkable ability to adapt to the constantly changing requirements of the custom mobile app development segment. Here we look at the top 5 reasons why Flutter is fast becoming an indispensable part of custom mobile application development: 1. Fast performing apps developed quickly One of the main reasons Flutter app development is becoming popular is that it is effective across platforms and speeds up the entire process of custom...

Introduction to Laravel caching
A common pain point in applications is optimizing and reducing the number of trips you have to take to the database. Say you have an e-commerce admin dashboard. Maybe you have a page that displays all inventory — every product, associated category, vendors, and more. A single page like this may perform dozens of calls to your database before the page can even display any data. If you don’t think about how to handle this, your application can quickly become slow and costly. One option to reduce the number of times you have to go to the database is through caching. Caching allows you to store specific data in application memory so that next time that query is hit, you already have the data on hand and won’t have to go back to the database for it. Keep in mind, this is different from browser caching, which is user-based. This article covers application caching, which happens at the application level and cannot be cleared by the user. Laravel has robust built-in functionality that makes caching a breeze. Let’s see it in action! For this demonstration, you will use a PlanetScale MySQL database to get a practice database up and running quickly. I promise this setup will be fast and painless! Create a free PlanetScale account. Create a new database either in the onboarding flow or by clicking “New database” > “Create new database“. Give your database a name and select the region closest to you. Click “Create database“. Once it’s finished initializing, you’ll land on the Overview page for your database. Click on the “Branches” tab and select the...
What Factors Impact The Success of Your Mobile App Development in 2021?
Mobile apps have become a trend-setter for every industry. They have become an essential part of every business that is looking to expand globally. Ever since apps were known for generating revenue and boosting businesses, everyone wants to go for it. If you own a business and have enough budget for app development, you can easily hire mobile app developers and start with your app. However, if you are a startup with a limited budget, you might want to tread carefully here. Mobile app development is not only about the budget. Of course, the cost factor is essential while developing. This also determines success. So, the question is, what makes an app ‘successful’? What are the essential factors we have to consider to make a mobile app development successful? Well, precisely, to make a mobile app successful, it should have user-centric features. Every Android app development company wants to have its app delivering excellently on the app stores as they spend a huge amount on app development. This helps users to fulfill their requirements, on-demand solutions, and demand to achieve the desired result. If we go through the latest applications, we will realize that they are all using the latest technologies in them. Technologies like AI, VR, AR, Machine Learning, etc are used to enhance the user experience. Let us consider an example here. What will a user first notice if he/she lands on your app? It’s its design elements – UI and UX. Then users will realize its features and the performance of the app. This is followed by the regularity of updates and bug fixes. In the...Journalists at threat after governments passed cyber security laws – NewsDay Zimbabwe
BY VARAIDZO MUDEWAIRI JOURNALISTS have been urged to protect themselves against digital surveillance threats after the country passed cyber security legislation. A statement by Fesmedia Africa yesterday said a survival toolkit has been developed in response to growing digital surveillance threats, and passing of cyber security laws by governments and other people that track and monitor journalists in order to muzzle them from carrying out their work. Fesmedia Africa said some of the countries that have passed cyber security legislation include Botswana, Zambia and Zimbabwe. “They have acquired sophisticated tools developed by an Israeli company, which they use to monitor the behaviour of citizens online,” Fesmedia Africa said. They said the affected journalists should report to international and local organisations for protection from surveillance. “A journalist, who is subjected to surveillance, or suspects being subjected to such, should notify these international support structures for journalists. They are very instrumental at documenting such cases, making them known through existing networks and exposing blatant abuse of surveillance especially by state and quasi- state actors. “Surveilled journalists should inform local organisations within their countries who work in conjunction with global organisers.” Fesmedia Africa said that journalism often takes place in contested environments, and the very act of exposing the truth can upset powerful people. “Journalists should set up dummy emails, set up investigation accounts, use VPN and browsers to keep themselves and their sources safe.” Fesmedia Africa said in 2018 the UN Passed the Right to Privacy in the Digital Age instrument which recognises the right to privacy and the need to limit surveillance. They also said that the Declaration of Principles...Why Choose React Native in 2021 — Rubyroid Labs
React Native remains one of the best technologies for building mobile apps in 2021. But why choose React Native Why choose React Native as development technology for your prospective app? For one, just look at the stats. In 2020, Statista named it “the most popular cross-platform mobile framework used by global developers,” according to a survey. Flutter got really close, booming in the past few years. Cordova, Ionic, Xamarin and other React Native alternatives have been left far behind. Is React Native going to keep its position through 2021? We think so. Consider this: Coinbase, the largest cryptocurrency exchange in the US, rebuilt its Android app using React Native earlier this year. And fuboTV, a popular US streaming service, is looking for React Native developers to build a sports wagering app. At Rubyroid Labs, we have helped develop more than 30 apps on React Native since 2013. Not every client has known which technology to use at the start. If you, too, are unsure about which framework to choose, write to us — we’ll see if this one will work. So why is this framework so popular? And why do leading companies use React Native for hybrid app development? Let’s take a closer look. Four Benefits of React Native The superpower of the framework is in its nature. If you compare React Native vs. Flutter or React Native vs. Ionic, you’ll see the main difference: the other two are engines, React Native is not. It operates more like a bridge linking the cross-platform code to an iOS/Android-native platform. When the cross-platform code executes a function, React Native will call...
Binomial distributions in practice | by Agnieszka Kujawska, PhD | Oct, 2021 | Towards Data Science
The ‘!’ notation is the factorial. As you might see, for non-negative integer x, it is calculated as the multiplication of all numbers up to x, for example: 2.2. The binomial density funtion (PMF) Now, we are ready to define the binomial density function as a probability of obtaining m successes in N Bernoulli trails: So, the binomial distribution is a discrete probability distribution of the number of successes (m) in a sequence of N independent repetitions of a given experiment, which asks yes-no (success-failure, 1–0) question, the probability of success is p, and the failure’s probability is q=1-p. Let’s consider an example. You are practicing free throws during basketball training. From the season statistics, we know that the probability that you will score a point is 75%. Your coach told you that if you score 17 points out of 20 attempts, you will start for the next match. What is the probability that you score exactly 17 points? We need to assume that the probability of a successful free throw shot is independent of the previous result (the mental strength does not play a role here). We also do not care about the order of scoring, such that it does not matter whether you fail first, third or last shot. Thus, this is a binomial distribution. We can use the binomial density function as given above and get: We can repeat this excercise for other scores. As a result, we get the binomial distribution plot (PDF): But you want to score at least 17 points, not exactly 17 points. So what is the probability that you will be...
