Implementing Micro Frontends in Angular: Step-By-Step Guide

Aggregated on: 2024-07-11 23:08:23

Micro frontends are architectural styles in which independently deliverable frontend applications form a unified whole. This method enables teams to work independently on different parts of an application for scalability and easier maintenance. This guide will demonstrate how to implement micro frontends in Angular applications, the benefits and challenges, and the steps with code samples. Benefits of Micro Frontends Scalability: Teams can develop, test, and deploy features independently, scaling the development process. Autonomous teams: Different teams can work on separate micro frontends, using their preferred tools and frameworks. Maintainability: Smaller codebases are easier to maintain, understand, and refactor. Incremental upgrades: Micro frontends can be updated incrementally without affecting the entire application. Challenges of Micro Frontends Complexity: Increased complexity in managing multiple repositories and coordinating deployments. Performance: Potential performance overhead due to multiple independent bundles. Shared state management: Managing shared state across micro frontends can be challenging. Consistency: Ensuring a consistent look and feel across different micro frontends requires careful planning. When more than one team works on various areas of an application, differences in design and user experience usually creep in. To mitigate this, a solid design system and common component library should be established across all teams. This includes defining a set of UI components, styles, and guidelines that are uniform across the application. It also requires regular communication and collaboration between teams to align on design decisions and consistency.

AI: Do You Trust It?

Aggregated on: 2024-07-11 20:08:23

We have lived in a period of AI shift for the past few years. AI is everywhere: searching, learning, text processing, code review, code writing assistance, and many other systems have arisen in recent years. It seems everyone is eager to apply AI wherever possible even where it might not be needed. I'm not an exception. Under the influence of this wave, I decided to try to create something on my own that would help me in everyday life. So here I will tell you my own story of writing an application with the use of AI, along with some thoughts about it, of course, which are rather contradictory. What Is the Task? As a developer in a distributed team, I usually need to explain my weekly progress to my colleagues. I know that for some it might look contradictory, but we prefer text-based reports over face-to-face communication. All the benefits of this approach have been mentioned many times already (like here, here, and here), and it’s just how we prefer to do it. So, after a while, we came up with a particular document format and structure for our weekly reports. It is called SIMBA. This format is extremely simple:

Create JWT Using DataWeave JWT Library

Aggregated on: 2024-07-11 17:08:23

Recently in one of my projects, there was a requirement to create JWT within the MuleSoft application and send that as an OAuth token to the backend for authentication. After doing some research, I got to know several ways to create JWT like Java code, DataWeave code, JWT sign module, etc. Java code can be complex to implement, Dataweave code does not work for the RSA algorithm and the client didn’t want to use a custom module like the JWT sign module. Finally, I got to know about the DataWeave JWT Library available in MuleSoft Exchange. In this blog, I will be describing the process of creating JWT using the Dataweave JWT Library available in Mulesoft Exchange which supports both HMAC and RSA algorithms.

Isolation in Testing With Kafka

Aggregated on: 2024-07-11 13:08:23

The experience of running Kafka in test scenarios has reached a high level of convenience thanks to the use of Test containers and enhanced support in Spring Boot 3.1 with the @ServiceConnection annotation. However, writing and maintaining integration tests with Kafka remains a challenge. This article describes an approach that significantly simplifies the testing process by ensuring test isolation and providing a set of tools to achieve this goal. With the successful implementation of isolation, Kafka tests can be organized in such a way that at the stage of result verification, there is full access to all messages that have arisen during the test, thereby avoiding the need for forced waiting methods such as Thread.sleep(). This method is suitable for use with Test containers, Embedded Kafka, or other methods of running the Kafka service (e.g., a local instance).

Data Migration From GaussDB to GBase8a

Aggregated on: 2024-07-10 20:08:23

Exporting Data From GaussDB Comparison of Export Methods Export Tool Export Steps Applicable Scenarios and Notes Using GDS Tool to Export Data to a Regular File SystemNote: The GDS tool must be installed on the server where the data files are exported Remote Export Mode: Export business data from the cluster to an external host. 1. Plan the export path, create GDS operation users, and set write permissions for the GDS user on the export path. 2. Install, configure, and start GDS on the server where data will be exported. 3. Create an external table in the cluster, with the location path in the format "gsfs://192.168.0.90:5000/".Local Export Mode: Export business data from the cluster to the host where the cluster nodes are located. This strategy is tailored for numerous small files. 1. Plan the export path and create directories to store exported data files on each DN in the cluster, such as "/output_data", and change the owner of this path to omm. 2. Install, configure, and start GDS on the server where data will be exported. 3. Create an external table in the cluster, with the location path in the format "file:///output_data/". GDS tools suitable for scenarios with high concurrency and large data exports. Utilizes multi-DN parallelism to export data from the database to data files, improving overall export performance. Does not support direct export to HDFS file system.Notes on Remote Export: 1. Supports concurrent export by multiple GDS services, but one GDS can only provide export services for one cluster at a time. 2. Configure GDS services within the same intranet as the cluster nodes. Export speed is affected by network bandwidth. The recommended network configuration is 10GE. 3. Supported data file formats: TEXT, CSV, and FIXED. Single-row data size must be <1GB.Notes on Local Export: 1. Data will be evenly split and generated in the specified folders on the cluster nodes, occupying disk space on the cluster nodes. 2. Supports data file formats: TEXT, CSV, and FIXED. Single-row data size must be <1GB. gs_dump and gs_dumpall Toolsgs_dump supports exporting a single database or its objects.gs_dumpall supports exporting all databases in the cluster or common global objects in each database. The tools support exporting content at the database level, schema level, and second level. Each level can be separately defined to export the entire content, only object definitions, or only data files. Step 1: The omm operating system user logs into any host with MPPDB service installed and executes: source $ {BIGDATA_HOME}/mppdb/.mppdbgs_profile command to start environment variablesStep 2: Use gs_dump to export the postgres database: gs_dump -W Bigdata@123 -U jack -f /home/omm/backup/postgres_backup.tar -p 25308 postgres -F t 1. Export the entire database information, including data and all object definitions. 2. Export the full information of all databases, including each database in the cluster and common global objects (including roles and tablespace information). 3. Export only all object definitions, including tablespace, database definitions, function definitions, schema definitions, table definitions, index definitions, and stored procedure definitions. 4. Export only data, excluding all object definitions.

Dynamic Watermarking on the JVM

Aggregated on: 2024-07-10 19:08:23

Displaying images on your website makes for an interesting problem: on one side, you want to make them publicly available; on the other, you want to protect them against undue use. The age-long method to achieve it is watermarking: A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal such as audio, video or image data. It is typically used to identify ownership of the copyright of such signal. "Watermarking" is the process of hiding digital information in a carrier signal; the hidden information should, but does not need to, contain a relation to the carrier signal. Digital watermarks may be used to verify the authenticity or integrity of the carrier signal or to show the identity of its owners. It is prominently used for tracing copyright infringements and for banknote authentication.

How DevSecOps Can Combat Zero-Day Threats

Aggregated on: 2024-07-10 14:08:23

Zero-day threats are becoming more dangerous than ever. Recently, bad actors have taken over the TikTok accounts of celebrities and brands through a zero-day hack. In late May to early June, reports of high-profile TikTok users losing control over their accounts started to surface after opening a direct message. The malware used for the attack was able to infect devices without the users downloading or installing anything. TikTok appeared unaware of the extent of the damage. The company’s spokesperson, Alex Haurek, said that the number of accounts compromised was “very small,” but he also declined to provide a specific number. He said they have been working with the owners of the affected accounts to restore access and that they have implemented measures to make sure the problem does not happen again.

How To Build an AI Knowledge Base With RAG

Aggregated on: 2024-07-09 23:23:22

Large Language Models are immensely powerful and can quickly generate intelligent and natural-sounding responses. Their major problem, however, is a limitation of training data – GPT-4, for instance, has a knowledge cutoff date in September 2021. This means that the model is unaware of any events or developments after this date. LLMs also have consistent troubles with the accuracy of information and “hallucinations” – coherent and logical, but factually incorrect responses. Finally, LLMs are unaware of specific, niche information, and can only generate responses on a certain level of generality. To solve these issues and make the LLM usable for specific and information-heavy tasks, LLMs can be connected to AI knowledge bases – repositories of information that consist of organized data – product documentation, articles, messages, and other materials. In this article, I explain how to create a knowledge base that would later be connected to the LLM model and enable it to generate factually correct and specific responses.

Mitigate the Security Challenges of Telecom 5G IoT Microservice Pods Architecture Using Istio

Aggregated on: 2024-07-09 23:23:22

Deploying microservices in a Kubernetes cluster is critical in 5G Telecom. However, it also introduces significant security risks. While firewall rules and proxies provide initial security, the default communication mechanisms within Kubernetes, such as unencrypted network traffic and lack of access control, are inherently insecure. This insecurity could compromise sensitive data. Therefore, implementing additional security measures within each microservice pod is not just a recommendation but a crucial step to ensure secure communication within the cluster. So, additional configuration inside each application is needed. Istio provides a robust solution to these challenges by effectively managing communication between individual 5G telecom microservice pods. With its control plane, Istio automatically injects a sidecar proxy into individual microservices pods, ensuring secure and efficient communication.

Securing Your Machine Identities Means Better Secrets Management

Aggregated on: 2024-07-09 23:23:22

In 2024, GitGuardian released the State of Secrets Sprawl report. The findings speak for themselves; with over 12.7 million secrets detected in GitHub public repos, it is clear that hard-coded plaintext credentials are a serious problem. Worse yet, it is a growing problem, year over year, with 10 million found the previous year and 6 million found the year before that. These are not cumulative findings! When we dig a little deeper into these numbers, one overwhelming fact springs out: specific secrets detected, the vast majority of which are API keys, outnumber generic secrets detected in our findings by a significant margin. This makes sense when you realize that API keys are used to authenticate specific services, devices, and workloads within our applications and pipelines to enable machine-to-machine communication. This is very much in line with research from CyberArk, machine identities outnumber human identities by a factor of 45 to one. This gap is only going to widen continually as we integrate more and more services in our codebases and with ever-increasing velocity.

Cache Wisely: How You Can Prevent Distributed System Failures

Aggregated on: 2024-07-09 23:23:22

Caching is often implemented as a generic solution when we think about improving the latency and availability characteristics of dependency service calls. Latency improves as we avoid the need to make the network round trip to the dependency service, and availability improves as we don’t need to worry about temporary downtimes of the dependency service given that the cache serves the required response that we are looking for. It is important to note that caching does not help if our requests to a dependency service lead to a distinct response every time, or if a client makes vastly different request types with not much overlap between responses. There are also additional constraints to using caching if our service cannot tolerate stale data. We won’t be delving into caching types, techniques, and applicability as those are covered broadly on the internet. Instead, we will focus on the less talked about risk with caching that gets ignored as systems evolve, and this puts the system at risk of a broad outage.

Enhancing Security With ZTNA in Hybrid and Multi-Cloud Deployments

Aggregated on: 2024-07-09 23:23:22

Today’s network infrastructure is rapidly changing with the adoption of hybrid and multi-cloud architectures to leverage the benefits of flexibility, scalability, and redundancy. These advantages come with their own set of challenges, particularly in securing access to resources and users spread across cloud environments. Zero Trust Network Access (ZTNA) ensures secure connectivity in diverse and complex infrastructures. Understanding ZTNA in Hybrid and Multi-Cloud Environments The Zero Trust Network Access (ZTNA) marks a major shift from the traditional perimeter-based security which treats traffic as untrustworthy, irrespective of its source. Network segmentation is not the only reliable method of providing security. ZTNA checks every access request based on user identity, device security posture, and contextual factors before granting access to applications and data.

Mastering Serverless Debugging

Aggregated on: 2024-07-09 06:23:22

Serverless computing has emerged as a transformative approach to deploying and managing applications. The theory is that by abstracting away the underlying infrastructure, developers can focus solely on writing code. While the benefits are clear—scalability, cost efficiency, and performance—debugging serverless applications presents unique challenges. This post explores effective strategies for debugging serverless applications, particularly focusing on AWS Lambda. Before I proceed I think it's important to disclose a bias: I am personally not a huge fan of Serverless or PaaS after I was burned badly by PaaS in the past. However, some smart people like Adam swear by it so I should keep an open mind.

Using Zero-Width Assertions in Regular Expressions

Aggregated on: 2024-07-08 21:23:22

Anchors ^ $ \b \A \Z Anchors in regular expressions allow you to specify the context in a string where your pattern should be matched. There are several types of anchors: ^ matches the start of a line (in multiline mode) or the start of the string (by default). $ matches the end of a line (in multiline mode) or the end of the string (by default). \A matches the start of the string. \Z or \z matches the end of the string. \b matches a word boundary (before the first letter of a word or after the last letter of a word). \B matches a position that is not a word boundary (between two letters or between two non-letter characters). These anchors are supported in Java, PHP, Python, Ruby, C#, and Go. In JavaScript, \A and \Z are not supported, but you can use ^ and $ instead of them; just remember to keep the multiline mode disabled.

Test Smells: Cleaning up Unit Tests

Aggregated on: 2024-07-08 21:23:22

In practical terms, knowing how not to write code might be as important as knowing how to write it. This goes for test code, too; and today, we're going to look at common mistakes that happen when writing unit tests. Although writing unit tests is common practice for programmers, tests are still often treated as second-class code. Writing good tests isn't easy — just as in any programming field, there are patterns and anti-patterns. There are some really helpful chapters on test smells in Gerard Meszaros's book about xUnit patterns — and more great stuff around the internet; however, it's always helpful to have practical examples.

In this blog on AWS, let’s do a comparison study between two filter tools available with Amazon CloudWatch Logs — Metric Filter and Subscription Filter, which play a crucial role in log data management, allowing you to analyze, monitor, and act on log data effectively. Metric Filter Metric Filters define the terms and patterns to look for in log data as it is sent to CloudWatch Logs. CloudWatch Logs uses these metric filters to turn log data into numerical CloudWatch metrics that you can graph or set an alarm on. For eg., you can create a metric to count the occurrences of the word “ERROR” in your logs & set an alarm if the count goes beyond a certain threshold.

Real-Time Testing: Best Practices Guide

Aggregated on: 2024-07-08 21:23:22

Real-time testing is a crucial part of the Software Development Life Cycle that involves testing software applications for their reliability and functionality in real-time. This involves simulating the real-time environment or scenarios to verify the performance of the software application under various load conditions. Due to this, real-time testing has become one of the major aspects of software testing. It has been popularized based on its ability to test the software application in its operational mode. In this fast-growing software industry, organizations struggle to maintain the pace of software application development and its release. In this process, testing application quality, performance, and functionality is the priority phase which helps ensure end-user requirements are fulfilled. However, software testing is a vast domain, and software applications have to undergo various stages of testing that vary from functional to non-functional testing as per software application requirements.

Enhancing Cloud Security: Integrating DevSecOps Practices Into Monitoring

Aggregated on: 2024-07-08 21:23:22

In the fast-changing world of tech, companies must get their apps out quickly but can't forget to keep them safe. Gone are the days when security checks happened only after making the app. Now, there's an intelligent way called DevSecOps that ties together software development lifecycle, security, and operations into one smooth process. Prolific DevSecOps practices ensure safety measures are part of every step in getting an app from idea to user's hands through continuous integration (CI) and delivery (CD), covering everything before launch and after it goes live. DevSecOps isn't just a fad; it marks a significant change in the overall production environment and in how people think about building and sending out software. By weaving security into each phase of app development cycle, devsecops teams can release secure software quicker than ever. They're better at finding and fixing security flaws early on, enhancing the traditional software development cycle and staying on top of legal rules for protecting data.

Aggregated on: 2024-07-08 21:23:22

Have you ever come across a situation in automated API testing where you were not able to identify the issue in the test failure and after debugging for multiple hours, you noticed that the data type of the value supplied in the response of the API had changed. Did you then notice that this was the core reason for the test failure? This type of scenario can generally happen when you have third-party APIs integrated into your application. A real-time example of such a scenario would be integrating with the Bank APIs for making a payment for your e-commerce application or integrating with third-party API which provides the registration and login functionality using two-factor authentication.

Understanding and Mitigating IP Spoofing Attacks

Aggregated on: 2024-07-08 21:23:22

Spoofing is a type of cyber-attack used by hackers to gain unauthorized access to a computer or a network, IP spoofing is the most common type of spoofing out of the other spoofing method. With IP Spoofing the attacker can hide the true source of the IP packets to make it difficult to know the origin of the attack. Once access to a network or a device/host is achieved, cybercriminals usually mine them for sensitive data, with computers they can turn into zombies and can be used to launch Denial-of-Service (DoS) attacks. What Is IP Spoofing? IP addresses are used for communication between devices on the internet. Cybercriminals use a false source IP address to hide and impersonate another system. Essentially making it harder for the destination system to detect. Such attacks come with the intent to steal sensitive data, infect your computer with malware or viruses, or even crash your server.

1. Hardware Configuration Recommendations CPU Ensure the BIOS settings are in non-power-saving mode to prevent the CPU from throttling. For servers using Intel CPUs that are not deployed in a multi-instance environment, it is recommended to disable the vm.zone_reclaim_mode parameter. To disable the NUMA parameter: Modify the current system value: echo 0 > /proc/sys/vm/zone_reclaim_mode Modify or add to the configuration file /etc/sysctl.conf: vm.zone_reclaim_mode = 0 Memory Configure the memory usage with the PCT parameter (gbase_memory_pct_target), which determines the percentage of the OS memory the gbased process can be used. After disabling the swap, reserve 20% for other programs. Configure the data heap, operator heap, and TEMP heap sizes as needed.

Build an Advanced RAG App: Query Rewriting

Aggregated on: 2024-07-06 14:53:21

In the last article, I established the basic architecture for a basic RAG app. In case you missed that, I recommend that you first read that article. That will set the base from which we can improve our RAG system. Also in that last article, I listed some common pitfalls that RAG applications tend to fail on. We will be tackling some of them with some advanced techniques in this article. To recap, a basic RAG app uses a separate knowledge base that aids the LLM in answering the user’s questions by providing it with more context. This is also called a retrieve-then-read approach.

Applying the Pareto Principle To Learn a New Programming Language

Aggregated on: 2024-07-05 22:08:20

In this article, I will discuss how you can apply the Pareto principle to quickly learn a new programming language and start solving real-world problems while you develop a deeper understanding of the programming language. What Is the Pareto Principle? The Pareto principle, also known as the 80/20 rule, states that for many outcomes, roughly 80% of consequences come from 20% of causes. Applying this to a personal level, 80% of your work-related output could come from only 20% of your time. I first came to know about this principle after reading the book "The 80/20 Principle: The Secret to Achieving More with Less" written by Richard Koch.
