2020 is going to be a competitive year especially for business people. A large number of startups and small businesses are outsourcing their projects to the best web development agencies because of the skilled resources, outsourcing-friendly policies, high-quality work, affordable price and favorable time zones they have.

But selecting a good company can be a daunting task because we are surrounded by a pool of such companies today. Keeping this in my mind, I have shortlisted some of these companies to help you choose the best one which offers world-class web development services at affordable rates.

I have checked the diversified portfolio, their tech teams expertise, client’s feedback, reviews from sites like Goodfirms and Clutch before making this list. Moreover, I have taken references from some popular platforms viz. hackernoon, dev.to, yourstory, quora, medium and habr.

Lets' dive into my research work on this which would surely meet your business requirements.

1) Sysbee



Locale: Pula, Croatia
Budget array: $1,000+
Employees strength:200 -250
Clientele: Infobip, Atheneum, IKEA

Sysbee is a group of systems engineers and infrastructure architects dedicated to bringing modern DevOps culture to small and medium enterprises, with more than 15 years of experience in the field of web services and cloud hosting.

One of the modules in the Windows kernel provides support for combining a set of file operations into an entity known as a transaction. Just like in databases, these entities are isolated and atomic. You can make some changes to the file system that won't be visible outside until you commit them. Or, as an alternative, you can always rollback everything. In any case, you act upon the group of operations as a whole. Precisely what needed to preserve consistency while installing software or updating our systems, right? If something goes wrong — the installer or even the whole system crashes — the transaction rolls back automatically.

From the very first time I saw an article about this incredible mechanism, I always wondered how the world would look like from the inside. And you know what? I just discovered a truly marvelous approach to force any process to operate within a predefined transaction, which this margin is too narrow to contain. Furthermore, most of the time, it does not even require administrative privileges.

Let's then talk about Windows internals, try out a new tool, and answer one question: what does it have to do with sandboxes?

Ruby on Rails is considered as one of the greatest frameworks for web development.

And еhere's a reason for that. Rails framework has a clear and standardized syntax, great community and lots of libraries and tools.

Are you looking for the best eCommerce platform for your store? Well, this is such an important and big decision as this decides the future of your business. There are various eCommerce platforms and Prestashop is also one of them.

Without stretching too much time, let’s move towards the best alternatives. Let’s have a look at them:

If you're reading this text, you've either thought that something was wrong with the headline or you've seen the name of a familiar computer game. VVVVVV is an indie platformer game that has stolen the hearts of many players by its pleasant external simplicity and no less pleasant internal complexity. A few days ago, VVVVVV turned 10 years, and the author of the game — Terry Cavanagh — celebrated this holiday by publishing its source code. What mind-boggling things is it hiding? Read the answer in this article.

Kotlin coroutines are much more than just lightweight threads — they are a new paradigm that helps developers to deal with concurrency in a structured and idiomatic way.

When developing an Android app one should consider many different things: taking long-running operations off the UI thread, handling lifecycle events, cancelling subscriptions, switching back to the UI thread to update the user interface. In the last couple of years RxJava became one of the most commonly used frameworks to solve this set of problems. In this article I’m going to guide you through the end-to-end feature migration from RxJava to coroutines.

Recently during the Google Developer Days Conference in China that was held on September 10, 2019, Flutter 1.9 was released along with the updated Dart 2.5 programming language.h

The major highlights from the conference can be summed into three major points:

• Google has announced Dart 2.5 programming update and a new Flutter 1.9 Version upgrade.
• Dart 2.5 will support calling C code and intelligent code completion.
• Flutter 1.9 will support iOS 13, macOS Catalina, and new Material widgets.

In this blog, I am going to discuss the major pointers in detail for you to understand the highlights and updates in detail!

Let’s begin!

What’s in store for Dart 2.5 as a programming language?

Dart is a Google borne programming language that has been used to develop mobile, web and desktop based applications. It is an object-oriented, class defined, garbage collected language with a C-style syntax, which is used to optionally compile into JavaScript.



The latest version of Dart 2.5 comes with these major highlights:

-> Support for Calling C Code straight through Dart using Dart FFI Library:

Developers who have knowledge about low-level programming languages will be excited from this announcement. The event also saw the launch of dart:ffi library, the preview of which allows calling into C code directly from Dart and Flutter.

PHP evolves continuously and they just released their latest PHP 7.4 update. Performance and speed keep advancing, as we have already been proved in the past PHP 7 releases. Preloading is one of the most thrilling new updates. It quickens script execution and makes code cleaner and faster due to the simplified common lines of code.

PHP is an important element in the world wide web and is used in over 79% of all websites. Well-known websites like Facebook, Wikipedia, WordPress and much more are using PHP.
We can see a double speed increase when looking at WordPress sites running PHP and comparing PHP 5 and 7. While using the latest PHP version out there — WordPress powered websites gain the most.

Data science is going to revolutionize this world completely in the coming years. The tough question among data scientists is that which programming language plays the most important role in data science? There are many programming languages used in data science including R, C++, Python.

In this blog, we are going to discuss two important programming languages namely Python and R. This will help you choose the best-fit language for your next data science project.

Python is an open-source, flexible, object-oriented and easy-to-use programming language. It has a large community base and consists of a rich set of libraries & tools. It is, in fact, the first choice of every data scientist.

Over some time in different jobs, I came across a need for several utilities that I couldn't find available at the time. And I saw that I needed them several times over and over again. So I wrote my own small library that I found very useful. So I just published it as an open-source java library.

Here is the Github link

Javadoc online is available here

Also, this library is available on Maven Central. Here are the Maven artifacts (the version 1.7.0.3 is the latest at the time of writing of this article but might change in the future. To check for the latest version search for artifact «MgntUtils» at http://search.maven.org/):

<dependency>
     <groupId>com.github.michaelgantman</groupId>
     <artifactId>MgntUtils</artifactId>
     <version>1.7.0.3</version>
</dependency>

 <dependency>
     <groupId>com.github.michaelgantman</groupId>

     <artifactId>MgntUtils</artifactId>
     <version>1.7.0.3</version>
     <classifier>sources</classifier>
</dependency>

Below is just a short explanation of what is there. The library comes with a nicely written (I hope) JavaDoc with a detailed description. So here is the list of features:

Launched in 2013, React has been successfully used to develop 1,004,124 websites in the past 6 years. The Javascript library React JS is known for giving simple programming experience and improved performance.

It was released by Facebook to resolve the issues of coding and maintenance with their ads. It was developed with an intention to increase and manage Facebook ads traffic. React has successfully delivered the expected outcomes throughout its journey.

Today we have another high-quality Microsoft project to be checked, which we'll heroically delve into trying to find errors with PVS-Studio. SARIF, an acronym for Static Analysis Interchange Format, which is a standard (file format), designed to interact and share the results of static analyzers with other tools: IDEs, complex code verification and analysis tools (e.g. SonarQube), continuous integration systems, etc. SARIF SDK, respectively, contains .NET developer tools to support SARIF as well as additional files.

Another release is out for the Windows Terminal preview! This release is labeled as v0.7 in the About section of the Terminal. As always, you can download the Terminal from the Microsoft Store and from the GitHub releases page. Here’s what’s new in this release:

Do you know there were 5 million apps in 2019? Out of these millions of apps, only a few are able to perform. There are many reasons for this but a major factor is the interactivity of an app.

No matter which product you are trying to sell, customers choose the one which allows them to get involved. Interactive apps are in demand for a long time. Are you wondering how can you make an interactive app?

The first thing which comes to our mind when we talk about interactive apps is the concept of single page application. This is because SPAs are known for their capacity to interact with the user by reloading some page elements dynamically depending upon the interaction by the user.

As per the stats, there were around 6 billion mobile app users in 2018-19. With increased demand for mobile apps, the number of mobile users has increased exponentially as compared to last years. Hence, it becomes necessary for every mobile app development company to follow some best app development practices in order to deliver the best mobility solution their users.

When we talk about best app development practices, it doesn't mean to leave the traditional approaches and start with new strategies. Actually, it requires to rely on the best old practices using modern app development tools and technologies. Before discussing in the technical terms, we first look at some best app development methodologies to come with a perfect mobile app in this competitive era.

When it comes to code in JavaScript, developers found reduce function as one of the toughest concepts to crack. According to Wikipedia, Reduce has multiple names viz. Accumulate, Fold, Compress and Aggregate. These names clearly indicate the meaning & working of reduce function. The idea behind this is to break down a structure into a single value. Hence, Reduce can be defined as a function which converts a list into any data type.

For example, you can reduce an array [5,4,3,2,1] into the value 15 by just adding them.

Reduce function keeps developers away from using loop in order to fold a list into a single value.

In this blog, you will learn ways to implement well-known functions using reduce as already done by developers in top software development company.

I have listed out 10 JavaScript utility functions recreated using reduce function. So, check out below these functions:-

• Map

Parameters used

array (to transform list of items), transform Function (is a function used to run on each element)

Working

By using the given transformFunction, each element in the given array get transformed and returns new array of items.

How to implement?

const map = (transformFunction, array1) =>
  array1.reduce((newArray1, xyz) => 
{
	newArray1.push(transformFunction(xyz));

	return newArray1;
  }, 
[]
);

Use case:

const double = (x) => x * 2;
const reverseString = (string) =>
  string
	.split('')
	.reverse()
	.join('');

map(double, [200, 300, 400]);

Output: [400, 600, 800]

map(reverseString, ['Hello Alka', 'I love cooking']);
// ['alkA olleH', ‘gnikooc evol I']

Yesterday my friend said something like "I’m writing simple offline app, I don’t need these streams and all that jazz". I was confused, but I thought, that there may be other coders in this delusion.

Below, literally in 50 lines I will show, on known example that reactivity is:

a) not about offline/online
b) very easy
c) very good for simplifying almost any code

Though it seems we are just a few months away from reaching 2020, these months are also important in the field of software development. Here in this article, we will see how the coming year 2020 will change the lives of software developers!

Future Software Development Is Here!

Traditional software development is about developing software by writing code and following some fixed rules. But the present-day software development witnessed a paradigm shift with advances in Artificial Intelligence, Machine Learning, and Deep Learning. With the integration of these three technologies, developers will be able to build software solutions that learn the instructions and add extra features and patterns in data that are needed for the desired outcome.

Let’s Try Out With Some Code

Over time, the neural network software development systems have become more complex in terms of integrations as well as layers of functionality and interfaces. Developers can build a very simple neural network with Python 3.6. Here’s an example of a program that does binary classification with 1 or 0.

Of course, we can start by creating a neural network class:


import numpy as np

X=np.array([[0,1,1,0],[0,1,1,1],[1,0,0,1]])
y=np.array([[0],[1],[1]])

Applying the Sigmoid function:

def sigmoid ():
   return 1/(1 + np.exp(-x))
def derivatives_sigmoid ():
   return x * (1-x)

Training the Model With Initial Weights and Biases:

epoch=10000
lr=0.1
inputlayer_neurons = X.shape[1]
hiddenlayer_neurons = 3
output_neurons = 1

wh=np.random.uniform(size=(inputlayer_neurons,hiddenlayer_neurons))
bh=np.random.uniform(size=(1,hiddenlayer_neurons))
wout=np.random.uniform(size=(hiddenlayer_neurons,output_neurons))
bout=np.random.uniform(size=(1,output_neurons))

For beginners, if you need help regarding neural networks, you can get in touch with top software development company.Or, you can hire AI/ML developers to work on your project.
