How to Avoid Risks Before Implementing Industrial IoT Solutions

Aggregated on: 2022-11-18 03:43:47

If you are wondering about the implementation of Enterprise IoT solutions, you understand that this process is rapidly developing all over the globe. Accoring to McKinsey Digital, 127 devices hooked up to the Internet for the first time every second in 2021, and in North America alone the worth of smart factories is expected to reach $500 billion in 2022. This trend is not surprising, as EIoT implementation helps to achieve a level of worker safety that was unattainable before, as well as new business models, and, therefore, new revenue flows. Using IoT devices, you will be able to get more information about manufacturing processes, employee and client behavior, and data that will help predict breakdowns and prevent downtime of equipment. Sounds tempting? All these benefits are achievable, but they depend on the company's ability to correctly assess the risks of EIoT implementation.

Performance Engineering Powered by Machine Learning

Aggregated on: 2022-11-18 03:13:47

This is an article from DZone's 2022 Performance and Site Reliability Trend Report.For more: Read the Report Software testing is straightforward — every input => known output. However, historically, a great deal of testing has been guesswork. We create user journeys, estimate load and think time, run tests, and compare the current result with the baseline. If we don't spot regressions, the build gets a thumbs up, and we move on. If there is a regression, back it goes. Most times, we already know the output even though it needs to be better defined — less ambiguous with clear boundaries of where a regression falls. Here is where machine learning (ML) systems and predictive analytics enter: to end ambiguity.

Spring Modulith: Have We Reached Modularity Maturity?

Aggregated on: 2022-11-18 02:13:47

One of the main reasons to design microservices is that they enforce strong module boundaries. However, the cons of microservices are so huge that it's like chopping off your right hand to learn to write with the left one; there are more manageable (and less painful!) ways to achieve the same result. Even since the microservices craze started, some cooler heads have prevailed. In particular, Oliver Drotbohm, a developer on the Spring framework, has been a long-time proponent of the moduliths alternative. The idea is to keep a monolith but design it around modules.

LocalStack in Action (Part 1)

Aggregated on: 2022-11-18 00:43:46

Provisioning AWS resources for your applications/organization can be complex—creating the AWS infrastructures (SQS, SNS, Lambda, S3...) with a fine-grained permissions model—and then trying to integrate your infrastructure with your applications will take time until you test it to ensure the whole flow is working as expected. In this article, I will introduce you to LocalStack, a cloud service emulator that runs in a single container on your laptop or in your CI environment. With LocalStack, you can run your AWS applications or lambdas entirely on your local machine without connecting to a remote cloud provider.

When To Use a Graph Database?

Aggregated on: 2022-11-17 23:58:46

The use of graph databases has grown massively in recent years, and they are becoming promising solutions for organizations in any industry. Their increased flexibility makes it easier to leverage relationships and connections in a way that traditional relational databases can't do. But how do you know when to use a graph database? In this article, we explore what to consider if you’re thinking of using a graph database and show how the best approach may be to not use one at all. What Is a Graph Database? A graph database is a type of database that uses graph theory as the foundation for its data model. Graph databases consider connectedness as a first-class citizen, making them better suited to represent connected data than more old-school relational databases.

7 Misunderstandings About Passkeys

Aggregated on: 2022-11-17 20:13:46

Rightfully Resistant to Change Password management is a thing that many people feel very strongly about. Many folks don’t like passwords and hope for a better way. But other folks have a solid system built around their password security and are rightfully very skeptical of systems that claim to improve on what they have. They have good reasons for liking their current setup and are hesitant to change what works for them. That’s wise. Passkeys Enter the Picture Thus many people are skeptical of passkeys, the new protocol from the FIDO Alliance that purports to drastically improve the safety, security, and user experience of logging in to websites and mobile applications.

Aggregated on: 2022-11-17 17:13:46

Although there are 4 million C++ programmers around the world, many of them lack the mastery needed to offer the services employers need. Therefore, there is still a shortage of these valuable experts. The reason C++ programmers have such excellent job security is that the language is complex and difficult to master. As a result, demand for programmers is surging these days. C++ programmers, in particular, can find stable employment. There are many great C++ jobs if you are a skilled programmer.

What Is CORS?

Aggregated on: 2022-11-17 13:58:46

Cross-Origin Resource Sharing (CORS) is a mechanism that supports secure requests and data transfers from outside origins (domain, scheme, or port). For example, example.com uses a text font that's hosted on fonts.com. When visiting, the user's browser will make a request for the font from fonts.com. Because fonts.com and example.com are two different origins, this is a cross-origin request. If fonts.com allows cross-origin resource sharing to example.com, then the browser will proceed with loading the font. Otherwise, the browser will cancel the request.

Daily 10 Tech Q&A With Bala

Aggregated on: 2022-11-16 19:58:46

With the growing number of cyber security threats, it is essential for everyone to know, mitigate, monitor, and prevent attacks on your apps. I have started this technology series as a small contribution to sharing the knowledge of whatever I have gone through so far. I hope my efforts will be useful to many software engineering aspirants and professionals who wish to use this information in their day-to-day work. 1. What Are the Important Aspects to Consider in Order to Secure Your Applications? Authentication and authorization ( if your authentication part is compromised, hackers can easily penetrate into a user app and do whatever they want, so it is important to safeguard your authentication mechanism to the app, API, or system. Logging: Application logs are essential and, more importantly, without which you won’t be able to identify any security incident; application-specific data is used for investigation. You should follow the best practices as much as you can to log the data. Encryption on data: There are multiple encryption algorithms that I will cover at the end of the video today; it is safe when you encrypt the data while transmitting from sender to receiver. Decryption is done at the receiver level to get the actual data. 2. Why Should You Use WAF Along With a Firewall? Firewalls are the first level of protection that permits or blocks network traffic based on IP addresses and port numbers. It can allow traffic to default ports http80 and https443.

PromCon EU 2022: All Things in the Prometheus Community

Aggregated on: 2022-11-16 19:28:46

For two days last week, I was on-site at the PromCon EU 2022 event in Munich, Germany. This is a very well-organized community event focused on all things in the open-source Prometheus project, including, for example, PromQL and PromLens. This article will be a bit of an overview, rather than a review of each specific talk, covering what I saw and found interesting between the common discussions and chatting that happens between talks in the hallways. Often these overlapping session starting times prohibit one from seeing everything at a conference.

Modular Data Centers Are Better for the Environment

Aggregated on: 2022-11-16 16:58:46

Data centers are the secret behind robust, successful networks — and they use a lot of energy. With every day leading humans to a more developed and connected world, these data centers are becoming focal points of the sustainability conversation for the tech sector. One of the top solutions experts present is modular data centers. These centers seek to optimize operations and energy efficiency for a greener future, but is the effort to make the shift worth it? How Different Are Modular Data Centers? Data centers are responsible for 1% of the world’s electricity demand. Though this doesn’t seem like a large number, it will only increase as technological needs increase. That translates to around 200 TWh of electricity, most of which runs on fossil fuels and isn’t optimized for current internet activity.

Why Use the NestJS Framework?

Aggregated on: 2022-11-16 16:58:46

As a front-end developer, I would like to say that the NestJs framework was the best choice to start touching the backend part of the applications. I always asked my tutor about design patterns, clean architecture, and microservices. He then showed me the link to the NestJs’s fully completed and very well-structured documentation. It was a good discovery for me to get lost on this page and learn about decorators, providers, dependency injection, testing, authentication, and more topics from different areas. What Is NestJs? First of all, what is this NestJs? It is an open-source Node.js framework for developing challenging backend systems that use the design paradigm convention over configuration that eliminates the need for explicit configuration by allowing developers to utilize common tools and code in a particular way.

What Is Roles-Based Access Control (RBAC)?

Aggregated on: 2022-11-16 16:28:46

Role-based access control (RBAC) is a security approach that uses roles to define what a user is and isn’t allowed to do. In an RBAC system, users are assigned roles with varying permissions for different resources, including files, databases, and applications. So, when a user tries to access a resource, the system will first find the roles associated with the user and then check if any of the roles have the appropriate permission. If so, the user is allowed to access the resource. If not, the user is denied access.

Native Dependency Injection in Swift

Aggregated on: 2022-11-16 13:13:46

In this article, we are going to go through a couple of solutions to a common problem when developing mobile applications, and this is Dependency Injection. We all saw a project that was calling singleton classes from any part of the code without any security when writing data to them, battling with race conditions, and coupling implementations to all these issues. You can also find many third-party libraries that can help to solve or at least manage these problems, but many times we don’t want or we can’t add extra dependencies; in this case, a good approach is to implement the solution that fits your needs in a basic but sufficient way and with native code.To start with this, we will go through the problem first and see what would actually help us. Let’s say we have a class called AViewModel that needs to use ServiceA; the first thing to think of is to instantiate the service in the initializer or directly inside the class like this:

Model Drift in Computer Vision Models: Understanding the Problem

Aggregated on: 2022-11-16 12:28:46

What Is a Computer Vision Model? Computer vision (CV) is a field within artificial intelligence and machine learning (ML) that involves computer programs interpreting the meaning of image and video inputs. A computer vision algorithm can analyze specific criteria in visual data and use its interpretations to implement predictive and decision-making tasks. Modern computer vision models are highly sophisticated and cover many use cases to automate critical decision-making systems and enhance business efficiency. As a type of machine learning algorithm, computer vision models are challenging to deploy.

Spring Boot for Cloud: Actuator

Aggregated on: 2022-11-16 02:58:45

In previous articles, we talked about some features of Spring Boot that are very useful in the development phase of our system: we described simplified dependency management and API development, for instance. In this article, we are going to cover functionalities that are related to a production environment. When a Spring Boot application is finally in production, it needs all the tools to manage and monitor it. This is especially important in complex scenarios like those related to micro-service systems. Spring Boot provides an effective solution to provide the required functionalities, the Actuator. The Actuator is a Spring Boot module with a set of features available as HTTP or JMX endpoints, or even with a remote SSH shell.

Spring Boot for Cloud: REST API Development

Aggregated on: 2022-11-16 02:58:45

There are two main ways by which microservice applications can interact with each other: REST services and messaging systems. The REST approach is the most common and will be treated in this article. We will see how Spring boot can make the development process of REST APIs fairly easy, with the use of a set of useful annotations and some implicit background behavior, like the serialization of model objects to JSON format. Another important issue is related to the documentation and sharing of APIs, and we will see that these concerns are addressed effectively with a solution named Swagger. Integrating Swagger with Spring Boot allows us to generate the documentation from the source code, as a Swagger JSON file, and even browse and manage all the exposed REST services with a web user interface.

Spring Boot for Cloud: Configuration and Dependencies

Aggregated on: 2022-11-16 02:28:45

The natural choice to implement a micro-service application in the realm of the Spring framework would be to use the Spring Cloud set of modules. But those modules cannot work without a solid platform underneath. Spring Boot sits on top of the Spring framework and is an effective base for Spring Cloud libraries (from this consideration the title of this article "Spring Boot for Cloud" makes some sense). Spring Boot has some features that can be of great help in reducing the complexity of micro-service architectures:

Integration Tests With Arquillian Extensions on the Payara Platform

Aggregated on: 2022-11-15 20:13:45

Arquillian is one of the most classical integration test frameworks for JVM (Java Virtual Machine)-based applications, currently maintained by Red Hat. Its main particularity consists in the fact that, in order to facilitate integration testing through the maven lifecycle, it allows the deployment of the tested applications on an embedded, managed, or remote Jakarta EE-compliant container, like Payara. From Manual To Automated Integration Testing Historically speaking, the integration testing process used to be a highly manual activity, consisting of deploying the application on the application server before running the test cases. This is especially due to the utilization of building tools like maven which default lifecycle provisions the integration test phase, named verify, just before install and deploy. This means that in-container integration tests cannot be performed in an out-of-the-box manner with such tools, because they are run before the deployment phase, despite the fact that, in order to be run, they require applications to be deployed. So, we find ourselves in a kind of circular problem here: in order to test the application we need to deploy it first, and, in order to deploy it, we need to test it first. This is why integration tests were traditionally performed manually.

The SQL Review Tool for Developers

Aggregated on: 2022-11-15 19:43:45

Treat SQL as code ("Why?" you may ask), which means all the reasons why we review other codes need to apply to SQL scripts. They interact straight with databases, and databases are too important. No matter how database vendors promise their products are stable and robust, databases are still pretty fragile. Even if we disregard the accidental "DROP TABLE" fiasco, ordinary queries like "SELECT FROM" can also overwhelm a database and bring it down. Let’s face it: databases are delicate, yet very few users understand how to treat them properly — meaning we should discipline the users’ behavior to some degree. Here’s where SQL review comes in. It is the practice of reviewing DDL and DML statements before applying them to the database. It is one of the most critical aspects of database schema management. In the past, DBAs were in charge of the database. They know the database best and, thus, should be the ones reviewing the SQL. This is reasonable, but there is a contradiction: developers (database users) cannot understand the many restrictions and want the most freedom. At the same time, DBAs insist that stability triumphs over everything.

Big Data and Cloud in Vertical Farming-based IoT Solutions

Aggregated on: 2022-11-15 17:58:45

Vertical farming-based IoT solutions are one of the key emerging trends in the agriculture industry today. These solutions are not only providing accurate information on plant growth statistics but also making operations more sustainable. With these solutions, farmers can track energy usage and soil composition, verify air quality, temperature and moisture levels, etc. and perform operations in a more efficient manner. In addition to processing data at rest, the real-time processing of sensor data i.e., the ability to process data collected by various sensors as it arrives, would form the major building blocks of these kinds of solutions. However, traditional data processing systems fall behind in handling real-time data, unstructured data, and scaling on demand. This is the reason why the usage of big data on the cloud in IoT-based solutions is on the rise, as it would require querying continuous data streams and detecting conditions quickly within a small interval from the time of receiving it. While big data supports data storage and structured as well as unstructured data processing, whereas cloud services are used for cost-effective scalable infrastructure.

Three Ways To Separate Plain Text From HTML Using Java

Aggregated on: 2022-11-15 17:28:45

On each webpage we visit, we are confronted with a huge variety of multimedia content, all of which is put together and presented using Hyper Text Markup Language (HTML). HTML is a basic programming language that many developers are familiar with, composed of elements that – when interpreted by a browser – typically form a coherent, organized, and intentional display with various customized elements. This code provides the framework for how we view images, videos, bodies of writing, hyperlinks, data entry fields, and anything else you can think of on a web page – and all that code is available for anyone to view with a simple right-click on any browser. Given the immense volume of formatting elements present in any complex HTML string, the actual subject of the code - the text contents and file paths buried within those strings - can be a bit difficult to access independently of those formatting specifications. If, for example, we want to review web copy and subsequently edit or manipulate that text in a meaningful way, we’re going to have a difficult time copying and pasting that information from the displayed web page directly. We’ll just end up with a mess of inconsistently formatted text riddled with hyperlinks, logos, disjointed tabs and spaces, and more. This isn’t to say that it can’t be done. We can, of course, copy small snippets of text from any web page and reformat those snippets to resemble their original form in rich text editors like Microsoft Word. The issue is that this “point and click” approach chews up valuable time in our workday, and if we need to scale up our operation to include multiple websites and thousands of characters worth of text, we’ll be doing ourselves a big disservice in the long run by attempting to do so manually.

How to Build Your Exchange Server Recovery Strategy to Overcome Ransomware Attacks

Aggregated on: 2022-11-15 14:13:45

Ransomware attacks on on-premises Exchange Servers are quite common as they store sensitive and confidential information and business data. The attackers often exploit vulnerabilities to gain access to the organization's network and steal or encrypt data for ransom. Even if attackers do not succeed in encrypting the data, they may leave a backdoor or cause other damage that can leave your server unusable or cause permanent data loss. That's why it's important to have a disaster recovery plan or recovery strategy ready to deal with such critical situations.

How I Used Render To Scale My Microservices App With Ease

Aggregated on: 2022-11-15 12:13:45

As a software lead and feature developer, I witnessed a team learn an important lesson about resource scaling and the cloud. Spoiler alert: the lesson was that if you’re not careful, scaling can get expensive! The team felt they had no choice but to keep increasing the number of instances for a given service that was under heavy load. When they finished scaling up, the number of instances was several times larger than the number of instances that were configured by default. What they didn’t realize at the time was that—despite the load returning back to a normal state—their extra instances remained in place.

GitOps Using Flux and Flagger

Aggregated on: 2022-11-15 04:43:45

GitOps as a practice has been in use since 2017 when Alexis Richardson coined the term. It transformed DevOps and automation. If you look at its core principles, it extends DevOps by treating Infrastructure as Code (IaC). Your deployment configuration is stored in a version control system (a.ka. Git), providing a single source of truth for both dev and ops. As the framework’s adoption increased, GitOps became the standard for continuous deployment in the cloud native space. Many agile teams adopt GitOps because of familiarity with git-based workflow for the release management of cloud-native workloads.

API Authentication Using Azure AD in IBM API Connect

Aggregated on: 2022-11-14 20:28:45

API authentication is necessary to secure API access from any unauthorized user. There are several ways to secure APIs. OAuth token validation is used to authenticate the user. One of the methods is to use Azure AD as an OAuth provider to secure an API invocation. The Azure AD provides an authentication token when the user sends a request to the login URL with a valid client_id and client_secret to the microsoftonline.com login. Architecture The below sequence diagram shows the design of the OAuth authentication process when Azure AD is used as an OAuth provider to authenticate REST API access implemented in IBM API Connect.

When migrating SQL Server from on-premises to the cloud, there is always an ask about how to migrate SSIS packages or other ETL jobs to the cloud. Azure Data Factory SSIS Integration Runtime (IR) offers to run SSIS packages in the cloud. However, in certain circumstances, those ETL jobs or SSIS packages run executables such as .EXE as a part of a workflow or ETL pipelines. It becomes more challenging if you are migrating SQL Server running on-premises to PaaS as there is no access to PaaS compute to run those executables.

In the first article, I have already covered a few issues you may face during such a transition to the Microsoft Graph REST API v1.0 with the MS Graph Java SDK. So, let's dive right into the following use cases. Read All Available Rooms and Room Lists of the Company (Getting Multiple Room Lists Is Not Possible) In many companies, rooms can be booked automatically when an Outlook appointment is created. This is possible because all rooms are assigned to an email address by the administration. By adding the email address of the resource to the attendees of the event, a booking process is automatically triggered, which checks if the room is available or not. There is also the option to create room lists, which also have their own email address. For this reason, we can start the availability check for multiple rooms at the same time. For instance, a room list can stand for a building.In case your business app has to get all rooms or room lists for a tenant. With the Microsoft Graph REST API v1.0, this can be done by using the Places API. The following example shows how to create a GET request in Java to read all rooms of a tenant (HTTP: GET /places/microsoft.graph.room):

The idea behind test-driven development (TDD) is that if you want to write good code, you have to write tests for it first and then figure out how to make them pass. This makes it easy to know if your code does what you want it to do, and makes it easier to refactor your code to be better and more flexible than ever before.

Today, an SPF record is a must-have DNS record for reliable email delivery. It is a type of email authentication to protect your emails from being forged. This secures your reputation from phishers and spoofers. Find out more about the Sender Policy Framework to increase the credibility of your product. What Is an SPF Record? One of the DNS resource records is TXT. It is mostly used to denote facts about the domain and provide information to outside sources. It’s a must-have for email authentication. For example, an email comes from a server to your internet service provider (ISP). ISP can authenticate the email using a dedicated TXT type record, SPF record. This record contains data about the trusted servers authorized by your domain so, your ISP can identify a source an email is coming from and detect a forged email. SPF or Sender Policy Framework is a primary (but not the only) way to authenticate your email.

Request-Response With REST/HTTP vs. Apache Kafka

Request-response communication with REST / HTTP is simple, well-understood, and supported by most technologies, products, and SaaS cloud services. Contrarily, data streaming with Apache Kafka is a fundamental change to process data continuously. HTTP and Kafka complement each other in various ways. This post explores the architectures and uses cases to leverage request-response together with data streaming in the control plane for management or in the data plane for producing and consuming events. Request-Response (HTTP) Versus Data Streaming (Apache Kafka) Prior to discussing the relationship between HTTP/REST and Apache Kafka, let's explore the concepts behind both. Traditionally, request-response and data streaming are two different paradigms.
