• 14 Kibana Plugins to Spice Up Your Data Visualizations

    Kibana is a powerful visualization platform designed specifically for log management with Elasticsearch. It already provides a lot built-in, but its open-source nature obviously lends it to some pretty cool simple and complicated additions from its community of devs. Some favorites include adding certain kinds of visualizations, API attachments, better integration between Kibana and other platforms, as well simple add-ons for flair in reports. Here are 14 open-source Kibana plugins that you can find through GitHub that are compatible with at least Kibana 7.x. If you have any other suggestions, feel free to please add descriptions and links in the comments below.

  • Install Powershell Module from Github Repository

    Hi there!

    The latest years Powershell started expansion to other platforms and now works on Windows, Linux, and MacOS (I even managed to start it on raspberry Pi Debian distro).

    And nowadays the main way for installing modules is PowerShell Gallery but in some situations, it still convenient to install modules directly from the source (the main reason — the main PowerShell modules repo configured to MyGet or NugetServer).

    And it can be painful to install Module from GitHub — you should download archive, find modules folder extract archive content and then copy module folder to the Powershell Profile directory.

    Moreover — people like me don't want to create a separate repository for each module (yes, I like the Release-Flow approach) so download and extract only the modules you are like -it even more difficult.

  • How To Implement JavaScript Utility Functions Using Reduce?



      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']

    • Cool WSL (Windows Subsystem for Linux) tips and tricks

        It's no secret I dig WSL (Windows Subsystem for Linux) and now that WSL2 is available in Windows Insiders Slow it's a great time to really explore the options that are available. What I'm finding is so interesting about WSL and how it relates to the Windows system around it is how you can cleanly move data between worlds. This isn't an experience you can easily have with full virtual machines, and it speaks to the tight integration of Linux and Windows.

      • Why 3D Printing Will Change the World?

          image

          1984, Orwell’s prophetic year of Big Brother, saw the release of the Mac which broke the idea that centralised control could ever be what it was before. That year also saw the first workable prototype for a 3D printer. Built by Charles Hull, the technology was then known as stereolithography. We know it as 3D printing, and that’s a term that covers a variety of different processes which may revolutionise all stages of the global manufacturing and distributing process. In that very science-fictional year, Hull set off a revolution that is only now seeing fruition. 3D printing continues to threaten the social and economic structures which preceded it. When we speak about 3D printing, we’re speaking of a general technique of successive printing layers to form a three-dimensional object at the end. From powder to paper to human tissue, these thin membranes are laid down like the construction of a plaster mask. From that simple concept, the 3D printer offers the reverse of Ford’s mass production revolution. Printing one item is now as cost-effective in some cases as manufacturing a thousand items in the traditional way.

          The computer powers 3d printing with printable files known as STLs, guiding the printers themselves as they construct, from the ground up, plastic homunculi that would awe medieval alchemists. It’s not quite the replicator from Star Trek, but it’s in the same Galaxy Class Starship.

          Our 3D printing future, however, isn’t liable to look like the utopian ideals Gene Roddenberry envisioned. Instead, we will see both positive and negative outcomes from these machines as the world finds ways to employ the emergent technology.

              • 9 Key Benefits Of Blockchain Technology In Sports Software

                  image

                  There are numerous benefits provided by blockchain technology for sports betting software. The nine key benefits are detailed below.

                  Security of Blockchain

                  When this technology is integrated into sports betting software, there is a permanent and unchangeable record in the transaction ledger providing transparency. Sportsbooks must be certain their betting data is delivered safely with all bets resolved correctly and quickly. This technology provides significantly better protection through the use of smart contracts. Decentralized actors handle the wagers with the smart contracts being executed automatically. Publicly written data cannot be altered. The complex system of the past is simplified and performed for much less than the traditional costs.

                  This provides better protection, flawless bet execution, enhanced data security and complete information transparency. The use of cryptocurrency significantly decreases the fees for payment processing. This reduces the margins for the sportsbook while offering players an increased chance to win. Once the bets have been resolved with a smart contract, the funds will be in the wallet of the better for almost immediate withdrawal. Any issues for even larger amounts are eliminated due to cryptocurrency payouts.

                  • How to Implement Tinder Swipe Cards in SwiftUI

                    In June, we heard about SwiftUI for the first time — a totally new way of creating and working with UI elements in iOS and macOS (also iPadOS) apps. It felt like Christmas in the summer. It's new, it's declarative, it's sexy! And now, just a few weeks after iOS 13 has been released, we can start to use SwiftUI in all our projects. Let's learn how to use this amazing tool that Apple gave us, to create the classic Tinder-esque Swipe Cards.

                    In this article, I would like to show you how to achieve a Tinder-like card view and behavior (swipe to action), with just a few lines of code.

                    To achieve this, we need to do the following things, in order:

                    • Create UserView
                    • Create NavigationView
                    • Create BottomBarView
                    • Create SwipeView
                    • Put all this together inside ContentView

                    So let's get started.

                          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.
