Automate Data Transformation Using IBM App Connect
IBM App Connect has introduced a new Artificial Intelligence (AI) feature that is capable of auto-generating data transformation expressions, and that helps accelerate your integration flow-building experience.
Data Mapping remains a fundamental part of integration development, but it takes time. An increasing number of applications, lack of naming standards, and nested field structures further compound the complexity for the integration developers. Once the mapping is done, data transformation is the next challenge for the users since each application expects data to be in a certain format. Also, while building integration flow, developers need to understand the format of the source and target data field and come up with transformation expressions that can change data from source to target format. This exercise is done manually and it takes a lot of time and skills to build such transformation expression.

Cordova: Communicating Between JavaScript and Java
Background
Cordova is an open-source cross-platform development framework that allows you to use HTML and JavaScript to develop apps across multiple platforms, such as Android and iOS. So how exactly does Cordova enable apps to run on different platforms and implement the functions? The abundant plugins in Cordova are the main reason, and free you to focus solely on app functions, without having to interact with the APIs at the OS level.
Introduction
Here, I'll use the Cordova plugin in HUAWEI Push Kit as an example to demonstrate how to call Java APIs in JavaScript through JavaScript-Java messaging. The following implementation principles can be applied to all other kits, except for Map Kit and Ads Kit (which will be detailed later), and help you master troubleshooting solutions.

Vicious (Test) Mockery of a Perl Modulino
Over the past two years, I've gotten back into playing Dungeons & Dragons, the famous tabletop fantasy role-playing game. As a software developer and musician, one of my favorite character classes to play is the bard, a magical and inspiring performer or wordsmith. The list of basic bardic spells includes Vicious Mockery, enchanting verbal barbs that have the power to psychically damage and disadvantage an opponent even if they don't understand the words. (Can you see why this is so appealing to a coder?)
Mocking has a role to play in software testing as well, in the form of mock objects that simulate parts of a system that are too brittle, too slow, too complicated, or otherwise too finicky to use in reality. They enable discrete unit testing without relying on dependencies external to the code being tested. Mocks are great for databases, web services, or other network resources where the goal is to test what you wrote, not what's out in "the cloud" somewhere.

2 Ways to Make a UUID Generator for Postgres
Postgres performs better than some other databases because it supports concurrent write operations without the need of read/write locks. Because it is completely ACID-compliant and provides transaction isolation and snapshots, many applications are using Postgres these days. Unfortunately, while PostgreSQL is great for storing and comparing UUID data, it lacks capabilities for creating UUID values in its core. Instead, it relies on third-party modules to create UUIDs using specified techniques. In this article, you'll learn about the PostgreSQL UUID data type and how to generate UUID values with examples utilizing various functions and modules.
What Is a UUID?
UUID stands for Universal Unique Identifier, defined by RFC 4122 and other related standards. A UUID is a series of lower-case hexadecimal digits separated by hyphens. UUIDs are a combination of 36-character sequences of numbers, letters, and dashes that are intended to be globally unique.

Data Governance and Data Management
Introduction
Enterprises that don’t embrace data or are late to the party face serious consequences compared to early adopters. As to talking about good data practices, most people associate the word with only a few of the multitude of practices that constitute a successfully run, data-driven enterprise.
Besides data analysis, data management is what readily comes to mind. Though equally universal — and perhaps are even more critical — data practice is the practice of data governance.

Can You Refactor JavaScript Safely Without Test Coverage?
Introduction
The conventional wisdom is that you should have good test coverage before refactoring your code. Making mistakes during refactoring will introduce defects in the software if they are not caught during testing. Such regression defects can annoy users, break the software, and even lead to customers abandoning the product.
The need for automated testing is especially high for JavaScript. In a dynamic language with functional constructs like JavaScript, it is harder to detect breakages statically. Additionally, JavaScript has many language details and quirks that are not well known or easy to remember.

Build Your IoT Application in a Day
IoT Application development is required today at all levels. But for people with very low coding knowledge, it is not easy to build/develop what is needed for them. With MQTTRoute, an IoT application framework with an inbuilt MQTT Broker, any early adopters or budding developers can develop, host and manage their application easily. This just leaves their development challenge for their IoT Server application. MQTT Broker comes with a default user interface, however, visualization needs to be built specific for each distinct vertical. We recently run an internal hackathon at Bevywise to build applications over our framework. Interestingly, we were able to build an IoT application in a day. The application built was an Industrial Furnace Monitoring. This blog portrays the hacks used to build the application.
IoT Application for Industrial Temperature Monitoring
Monitoring and control of the temperature of the furnaces is crucial with respect to its usage in the industries as it directly affects the quality of the product that is being created. We have created a simulated device using IoT Simulator similar to a monitoring edge device that pushes data to the MQTT Broker. The goals set for the application were:

Integrating SCTL Into DistSQL's RAL
In the previous article “An Introduction to DistSQL” written by Haoran Meng, the Apache ShardingSphere Committer shared the motivating reasons behind the design of DistSQL, explained its syntax system, and impressively showcased how you can use one SQL to create a sharding table.
Recently, the ShardingSphere community has redesigned the SCTL grammar and the execution engine, integrating SCTL into the DistSQL syntax system. Now RAL contains the old SCTL function, making ShardingSphere’s command language even more convenient for database management. Today, our community author would like to introduce the changes and elaborate on how you can use the new RAL command lines. We always pursue a better user experience, and the upgrade we developed this time is just another typical example.

What Is LoRa IoT?
There are many technical solutions for the endpoint Netcom transmission technology of the internet of things (IoT). The more famous technical solutions include NB-IoT, Lora, WiFi, Bluetooth, ZigBee, dustl, and sub GHz.
Different communication technologies have different characteristics and have their own application scenarios. Among them, Lora and Nb-IoT are the most used and most concerned in the Internet of things application scenarios. Lora IoT technology can meet long-distance and low-power data transmission. This application scenario can not be fully met by other IoT communication technologies, which is also the original intention of Lora IoT technology.

Developers That Embrace Security Add Personal, Organizational Value
While the relationship between software development and security hasn't always been harmonious, recent research suggests the two are becoming much more aligned. In one study, almost half of developers said they had prioritized learning or improving AppSec/secure programming since the pandemic began. In another study, 79 percent said the importance of secure code is increasing in prominence.
This long-awaited meeting of the minds is being driven in large part by astronomical increases in cyberattacks, which are happening on average every 39 seconds. Meanwhile, 60 percent of developers are releasing code two times faster than before. So, while developers are primarily motivated by creating great software, increasingly they are making efforts to ensure that development is complementary to security. The alternative — creating insecure code that puts attackers in the headlines — makes it imperative for developers to incorporate security wherever possible.

The Anatomy of an IoT Solution
Artificial intelligence relies on data. One of the leading ways to collect data these days is by using the Internet of Things. IoT connectivity is often used in devices containing sensors of some sort, allowing us to automatically collect information that either was not collectible before or which needed a human to collect it. Let’s go on a crash course on how you build an IoT platform or IoT device architecture, and which layers work together to make up such a solution. For this example, our IoT connectivity will center around cellular and the use of IoT SIM cards.
To begin with, it’s important to realize that there are four individual layers involved in building an IoT solution. Starting from the bottom — with individual frontline devices containing IoT SIM cards on-board — and working upwards to the networks over which your data is transmitted, and the IT applications that let you manage and control your entire fleet of IoT SIM cards. The layer hierarchy is arranged as follows.

The 10 Commandments for Performing a Data Science Project
In designing a data science project, establishing what we, or the users we are building models for, want to achieve is vital, but this understanding only provides a blueprint for success. To truly deliver against a well-established brief, data science teams must follow best practices in executing the project. To help establish what that might mean, I have come up with ten points to provide a framework that can be applied to any data science project.
1. Understand the Problem
The most fundamental part of solving any problem is knowing exactly what problem you are solving. Make sure that you understand what you are trying to predict, any constraints, and what the ultimate purpose for this project will be. Ask questions early on and validate your understanding with peers, domain experts, and end-users. If you find that answers are aligning with your understanding, you know that you are on the right path.

Video on Demand (VOD) Processing Using AWS
The demand for video is growing, and even more, businesses find infinite possibilities in this sector. We’re not just referring to entertainment or instructional materials here. Content providers, small businesses, and corporate brands are all benefiting from video on demand. Brands can build stronger relationships with their customers by offering them access to the information they want, whenever and however they want it. Thus, such visualization became the most convenient way to share data with software users.
VOD (video on demand) refers to any content delivery method that allows users to select when, where, and how they interact with media integration. This can be accomplished by either simultaneous broadcasting from an internet source or by the user downloading the video to a personal device for subsequent viewing. This is in contrast to traditional streaming, when the viewer may only see their film on a gadget with a satellite or cable connection at a certain period.

How Technical Operations Can Build on the Success of Data Science Notebooks
Data science notebooks, a popular document format used for publishing code, results, and explanations in readable and executable form, broke new ground by combining an ongoing narrative with interactive elements and displays. The result was a new way to capture and transfer knowledge about the process of discovering insights. By studying why data science notebooks have worked so well, we can understand more about related areas with similar characteristics, such as Technology Operations (TechOps).
At first glance, many of the attributes of data science notebooks also apply to TechOps. However, the data scientist and TechOps cohort have different objectives. A data scientist is interested in variable results based on changing elements within queries. A TechOps team responsible for complex operational systems looks for variables and patterns, seeks to understand the root cause, and takes corrective action. Data science notebooks are conducive to instruction and are easy to change. However, in a production operations setting, things need to be repeatable rather than variable. To align with the different user needs in TechOps, the notebook concept evolved into runbooks.
