Knowledge Graph With ChatGPT

Aggregated on: Mon Apr 03 2023 17:15:08 GMT+0000 (Coordinated Universal Time)

GPT fascinates. I was keen to evaluate my fascination firsthand. This is an extension of some custom code I had written to convert natural language into a "meaningful" representation in a graph but with relatively simple text, which was about the use of natural plants for the treatment of common ailments. To set some context, I did my share of nltk/ NLP learning when I labored and converted the contents of a book to a graph took more than a few weekends and loads of stackoverflow/d3.js threads to fix my errors and clean up code. With that experience, I set out this evening to 'test drive' the GPT engine. I took up two relatively simple use cases, with one being an attempt at summarizing the NIST 800 sp 53 control catalog in a simple graph, while the other was relatively more human imagination-driven, with me wanting to narrate a simple story of the "boy who cried wolf" using Neo4j.

A Developer's Dilemma: Flutter vs. React Native

Aggregated on: Mon Apr 03 2023 15:00:08 GMT+0000 (Coordinated Universal Time)

A few years ago, if you or your team decided to develop a mobile app for both iOS and Android, you would be required to maintain two codebases, one for each platform. This meant either learning or hiring developers well-versed in Swift and/or Objective-C(for iOS) and Kotlin and/or Java(for Android), the primary programming languages used to build native apps for these platforms. As you can imagine, this not only puts a strain on your resources and budget allocation but also involves longer development cycles and painstaking efforts to ensure consistency between both apps. With the advent of cross-platform app development frameworks in the last few years, mobile app developers and companies are increasingly moving or at least considering using these technologies to build their mobile apps. The primary reason is that these frameworks enable developers to write code only once and build for both Android and iOS. Maintaining a single codebase significantly reduces your time-to-launch and ensures a high level of consistency between both apps. We will discuss in detail in a bit how this is made possible by React Native and Flutter, which are the two most popular cross-platform mobile app development frameworks at the moment. React Native is a Facebook(Now Meta) project and was released publicly about two years before Google released the initial version of Flutter in 2017. Before the emergence of these two frameworks, there were a few other options for developers, like Xamarin, Cordova, and Ionic, but they have since fallen out of favor because of many complexity and performance issues. There is a relatively recent effort by the JetBrains team(the company that built some of the popular IDEs) called Kotlin Multiplatform mobile. However, it is still in Beta and not as popular as React Native or Flutter.

Understanding AVL Trees in C#: A Guide to Self-Balancing Binary Search Trees

Aggregated on: Mon Apr 03 2023 14:00:08 GMT+0000 (Coordinated Universal Time)

In my previous article, we discussed the binary search tree and its implementation in C#. We learned that this data structure allows for fast searching, insertion, and deletion of elements in logarithmic time. Still, if the tree is not balanced properly, its performance can suffer greatly. We also noted that there is a more advanced tree called AVL with self-balancing, which guarantees logarithmic time complexity for all operations, regardless of the incoming data. In this article, we will continue our exploration of binary search trees by diving deeper into AVL Trees. We will discuss their structure, properties, and implementation details and compare them to other self-balancing trees. We will also provide examples of AVL Trees in action and demonstrate how they solve the problem of unbalanced trees. By the end of this article, you will have a solid understanding of AVL Trees and be equipped with the knowledge to use them effectively in your own code.

Developing Saga Participant Code for Compensating Transactions

Aggregated on: Mon Apr 03 2023 03:45:08 GMT+0000 (Coordinated Universal Time)

The saga pattern is used to provide data integrity between multiple services and to do so for potentially long-running transactions. There are many, cursory as they tend to be, blogs written on sagas and long-running transactions. In this piece, I will not go into detail comparing the advantages and disadvantages of sagas with XA two-phase commit (2PC), distributed locking, etc., and will simply state that XA and 2PC require distributed locks (con) which manage ACID properties such that the user can simply execute rollback or commit (pro) whereas sagas use local transactions only and so do not require distributed locks (pro) but require the user to implement compensation, etc. logic (con). As Teddy Roosevelt said, “Nothing worth having comes easy.” What I will do is show a full code example of a microservices application involving a saga, including participant compensation logic, which can be found at this repo.

How To Perform Sentiment Analysis and Classification on Text (In Java)

Aggregated on: Sat Apr 01 2023 12:45:07 GMT+0000 (Coordinated Universal Time)

In much the same way mutual empathy defines the development of long-term relationships with our friends, it also plays a key role in defining the success of our business’ relationship with its customers. When customers take the time to type their thoughts and feelings into a review for a product or service, share their feelings through a social media platform, or provide feedback through some similar medium, it behooves us to empathize with them as fellow human beings and determine how they collectively feel about what they experienced. Using programmatic solutions, we can quickly analyze and then adjust (or maintain) the experience we provide to our customers at scale, efficiently improving customer relationships with our brand. Of course, unlike the human brain, computers aren’t raised and socialized to draw specific emotional conclusions from an evolving human language. They need to be trained to do so – and that’s where the field of sentiment analysis and classification comes into play. Using Natural Language Processing (NLP) techniques, we can train Machine Learning algorithms to analyze and classify unique sentiments in text.

Sorting can take a lot of time when dealing with large amounts of data. It would be great if, instead of sorting the data every time, we could directly write them into memory in the correct position where they would already be sorted. This would allow us to always know in advance where to search for them, for example, starting from the center. We would know exactly where to go; to the left, discarding half of the data on the right, or to the right, discarding half of the data on the left. This means that the number of elements on each search operation would be halved. This gives us nothing but fast logarithmic complexity.
