Lucene is most powerful and widely used Search engine. Here is the list of 7 search engines which is built on top of Lucene. You could imagine how powerful they are.
Apache Cassandra was designed by Facebook and was open-sourced in July 2008. It is regarded as perfect choice when the users demand scalability and high availability without any impact towards performance. Apache Cassandra is highly scalable, high-performance distributed database designed to handle large voluminous amounts of data across many commodity servers with no failure.
In Web development, there will be always a need to display content in a large list. Rendering a large list will slow down the web page load and increase the First Contentful Paint(FCP). Usually large lists are displayed in a paginated grid where user has to move around pages by clicking next. It will be good user experience, if the same page provides data of large list as and when we scroll.
Exonum is an extensible open source blockchain framework for building private blockchains which offers outstanding performance, data security, as well as fault tolerance.

AbanteCart is a free, open source shopping cart that was built by developers with a passion for free and accessible software. Founded in 2010 (launched in 2011), the platform is coded in PHP and supports MySQL. AbanteCart’s easy to use admin and basic layout management tool make this open source solution both easy to use and customizable, depending on the skills of the user. AbanteCart is very user-friendly, it is entirely possible for a user with little to no coding experience to set up and use this cart. If the user would be limited to the themes and features available in base AbanteCart, there is a marketplace where third-party extensions or plugins come to the rescue.
Next.js is one of the easy-to-learn frameworks for server-side pre-render pages for client-side web applications. In this blog, we will see how we can fetch data from API and make it pre-render pages. Also, let's see how forms work in Next.js and collect the data without maintaining the database.
We knew that Apace Spark- the most famous parallel computing model or processing the massive data set is written in Scala programming language. The Apace foundation offered a tool to support the Python in Spark which was named PySpark. The PySpark allows us to use RDDs in Python programming language through a library called Py4j. This article provides basic introduction about PySpark, RDD, MLib, Broadcase and Accumulator.
The first thing I do when I create a project is to create the debugger launch config at the `.vscode` folder. Debuggers help me to avoid putting print statements and building the program again. I always wondered how a debugger can stop the program on the line number I want and be able to inspect variables. Debugger workings have always been dark magic for me. At last, I managed to learn dark art by reading several articles and groking the source code of delve.
As enterprises struggle to save and analyze more and more data, data quality suffers. Real world data contains multiple records belonging to the same customer. These records can be in single or multiple systems and they have variations across fields which makes it hard to combine them together, especially with growing data volumes. This hurts customer analytics and no AI algorithm for segmentation can produce right results.
Lucidworks Enterprise search solution is built on top of Apache Solr. It scales seamlessly w/sub-second response times under extreme query loads for multi-billion document collections. It has user friendly UI, which does all the job of configuration and search.
Text editors are mainly used by programmers and developers for manipulating plain text source code, editing configuration files or preparing documentation and even viewing error logs. Text editors is a piece of software which enables to create, modify and delete files that a programmer is using while creating website or mobile app.In this article, we will discuss about top 7 all-round performing text editors which is highly supportive for programmers.
The best way to design a system for handling bulk workloads is to make it a batch system. If we are already using Spring, it will be easy to add a Spring Batch to the project. Spring batch provides a lot of boiler plate features required for batch processing like chunk based processing, transaction management and declarative input/output operations. It also provides job control for start, stop, restart, retry and skip processing also.
In my software development career, I have always been attracted to new technologies and innovative solutions. Project by project, I have been exploring something new, discovering and implementing different approaches and trying new solutions. When Android TV showed up, I set a new personal goal. I described my impressions and the overall opinion on the application development for Android TV right here. Hope you will find it useful and interesting.
OpenSSL is a general purpose cryptographty toolkit that provides an open source implementation of Transport Layer Security(TLS) and Secure Socket Layer(SSL) protocols. It is written in C,assembly and Perl language but wrappers are available in all languages. This article explains about OpenSSL commands.
Most of the cloud services provide API to fetch their data. But data will be given as paginated results as returning the complete data will overshoot the response payload. To discover the complete list of books or e-courses or cloud machine details, we need to call the API page-wise till the end. In this scenario, we can use Spring Batch to get the data page by page and dump it into a file.
MongoDB is a popular and widely used open source NoSQL database. MongoDB is a distributed database at its core, so high availability, horizontal scaling, and geographic distribution is quite possible. It is licensed under Server Side Public License. Recently they moved to Server Side Public License, before that MongoDB was released under AGPL. This article will provide basic example to connect and work with MongoDB using Java.
Blockchain is buzzing across the world with its endless potential for disrupting a broad spectrum of the industries beyond the storage and transferring the values. Cryptocurrencies are revolutionizing variant industries and plenty of people talk about it with and their potential. Blockchain technology may have been made for bitcoins but it has immense potential for making the transactions secure and exciting. The technology is not ubiquitous but it already seems to be disrupting a huge number of the highly centralized industries that demonstrate practical use cases for changing the way businesses are done.
Solr and Elastic Search are built on top of Lucene. Both are open source and both have extra features which makes programmer life easy. This article explains the difference and the best situation to choose between them.
You would have seen a lot of blogs for paypal php integration with REST api which is driven completely in the backend. For checkout, paypal provides an easy way to checkout for client side ready-to-use smart button payment. This approach will work only from the frontend, which will not be safe and difficult to reconcile as the backend does not have any information about it. Server side integration with the paypal smart button will help us to reconcile or track the payments even after some issues in the users payment journey. In this blog, we have walkthrough the paypal smart button with server side php laravel integration.
Apache OpenNLP is a library for natural language processing using machine learning. In this article, we will explore document/text classification by training with sample data and then execute to get its results. We will use plain training model as one example and then training using Navie Bayes Algorithm.
