PSA: A pretty clever phishing email

I got a message warning me that my Twitter account was about to be suspended for suspicious activity, inviting me to click a button to prevent this. The URL the button went to *was* an x.com link, but it used a security vulnerability in Twitter's backend that allowed redirections to push me to an OATH server that would prompt me for my Twitter login and 2FA, and then send the attacker a valid token they could use to take over my account.

Here's the (redacted) attack link:

https://x.com/ [BREAK INSERTED] i/oauth2/authorize?response_type=code&client_id= [UNIQUE ID REMOVED] Q&redirect_uri=https%3A%2F%2Ftwo.opensourced.us%2Fapi%2Fcallback%3Fi%3Dtwit&scope=tweet.read+users.read+mute.write+tweet.write+tweet.moderate.write+offline.access&code_challenge= [UNIQUE ID REMOVED] &code_challenge_method=plain

I don't care how standardized it is, I still hate oauth2. there's rarely good, comprehensive client support, it's designed with a "make an app to extend our website" design behind it. so now I have to create a service account and then do this stupid authorization flow that requires opening the browser to get the bearer and refresh tokens. just give me a fucking API key please

I am happy to announce that MochiDex is now officially public and you can now invite it to your servers. The bot allows you to catch, collect, and trade mochis.

Each mochi has its own card that includes art, their stats and their ability. Currently around half the mochi's have original art in their card, but eventually every mochi will have art! The art has been made by many different artists in the fandom and I hope you enjoy their work .

Right now we have added 64 mochis, but we don't plan on stopping until every Hetalia character is in the bot . Only 29 of these mochis were designed by Himaruya, so we have had to design mochis for most of the cast.

MochiDex Setup:

Click this link that allows you to invite the bot: https://discord.com/oauth2/authorize?client_id=1151205638521770035&scope=bot+applications.commands&permissions=537193536

Once the bot joins the server an admin needs to do the "/config channel" command to choose in which channel they would like the mochis to spawn

After doing that you just have to wait! The mochis can take around 45 to 55 minutes to spawn, they can spawn even earlier, it all depends on server activity!

4. Whichever mochi spawns depends on it's rarity, each mochi has a rarity which decides its chance to spawn. Some mochis like America are very rare, and others like Latvia are very common. Keep that in mind when trading

Oh and by the way, currently until November 3, the bot is having a Halloween event during which you can get rare "spooky" variants that change the card's theme.

We also have a discord server where you can find the rarity list, see updates and make questions/suggestions! Feel free to join!

Spring Security Using Facebook Authorization: A Comprehensive Guide

In today's digital landscape, integrating third-party login mechanisms into applications has become a standard practice. It enhances user experience by allowing users to log in with their existing social media accounts. In this blog post, we will walk through the process of integrating Facebook authorization into a Spring Boot application using Spring Security.

Table of Contents

Introduction

Prerequisites

Setting Up Facebook Developer Account

Creating a Spring Boot Application

Configuring Spring Security for OAuth2 Login

Handling Facebook User Data

Testing the Integration

Conclusion

1. Introduction

OAuth2 is an open standard for access delegation, commonly used for token-based authentication. Facebook, among other social media platforms, supports OAuth2, making it possible to integrate Facebook login into your Spring Boot application.

2. Prerequisites

Before we start, ensure you have the following:

JDK 11 or later

Maven

An IDE (e.g., IntelliJ IDEA or Eclipse)

A Facebook Developer account

3. Setting Up Facebook Developer Account

To use Facebook login, you need to create an app on the Facebook Developer portal:

Go to the Facebook Developer website and log in.

Click on "My Apps" and then "Create App."

Choose an app type (e.g., "For Everything Else") and provide the required details.

Once the app is created, go to "Settings" > "Basic" and note down the App ID and App Secret.

Add a product, select "Facebook Login," and configure the Valid OAuth Redirect URIs to http://localhost:8080/login/oauth2/code/facebook.

4. Creating a Spring Boot Application

Create a new Spring Boot project with the necessary dependencies. You can use Spring Initializr or add the dependencies manually to your pom.xml.

Dependencies

<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-oauth2-client</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> </dependencies>

5. Configuring Spring Security for OAuth2 Login

Next, configure Spring Security to use Facebook for OAuth2 login.

application.properties

Add your Facebook app credentials to src/main/resources/application.properties.spring.security.oauth2.client.registration.facebook.client-id=YOUR_FACEBOOK_APP_ID spring.security.oauth2.client.registration.facebook.client-secret=YOUR_FACEBOOK_APP_SECRET spring.security.oauth2.client.registration.facebook.redirect-uri-template={baseUrl}/login/oauth2/code/{registrationId} spring.security.oauth2.client.registration.facebook.scope=email,public_profile spring.security.oauth2.client.registration.facebook.client-name=Facebook spring.security.oauth2.client.registration.facebook.authorization-grant-type=authorization_code spring.security.oauth2.client.provider.facebook.authorization-uri=https://www.facebook.com/v11.0/dialog/oauth spring.security.oauth2.client.provider.facebook.token-uri=https://graph.facebook.com/v11.0/oauth/access_token spring.security.oauth2.client.provider.facebook.user-info-uri=https://graph.facebook.com/me?fields=id,name,email spring.security.oauth2.client.provider.facebook.user-name-attribute=id

Security Configuration

Create a security configuration class to handle the OAuth2 login.import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.security.config.annotation.web.builders.HttpSecurity; import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity; import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; import org.springframework.security.oauth2.client.oidc.userinfo.OidcUserService; import org.springframework.security.oauth2.client.userinfo.DefaultOAuth2UserService; import org.springframework.security.oauth2.client.userinfo.OAuth2UserService; import org.springframework.security.oauth2.core.oidc.user.OidcUser; import org.springframework.security.oauth2.core.user.OAuth2User; import org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler; @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests(authorizeRequests -> authorizeRequests .antMatchers("/", "/error", "/webjars/**").permitAll() .anyRequest().authenticated() ) .oauth2Login(oauth2Login -> oauth2Login .loginPage("/login") .userInfoEndpoint(userInfoEndpoint -> userInfoEndpoint .oidcUserService(this.oidcUserService()) .userService(this.oAuth2UserService()) ) .failureHandler(new SimpleUrlAuthenticationFailureHandler()) ); } private OAuth2UserService<OidcUserRequest, OidcUser> oidcUserService() { final OidcUserService delegate = new OidcUserService(); return (userRequest) -> { OidcUser oidcUser = delegate.loadUser(userRequest); // Custom logic here return oidcUser; }; } private OAuth2UserService<OAuth2UserRequest, OAuth2User> oAuth2UserService() { final DefaultOAuth2UserService delegate = new DefaultOAuth2UserService(); return (userRequest) -> { OAuth2User oAuth2User = delegate.loadUser(userRequest); // Custom logic here return oAuth2User; }; } }

6. Handling Facebook User Data

After a successful login, you might want to handle and display user data.

Custom User Service

Create a custom service to process user details.import org.springframework.security.oauth2.core.user.OAuth2User; import org.springframework.security.oauth2.core.user.OAuth2UserAuthority; import org.springframework.security.oauth2.client.userinfo.OAuth2UserService; import org.springframework.security.oauth2.client.oidc.userinfo.OidcUserService; import org.springframework.security.oauth2.core.oidc.user.OidcUser; import org.springframework.security.oauth2.client.userinfo.DefaultOAuth2UserService; import org.springframework.security.oauth2.client.oidc.userinfo.OidcUserRequest; import org.springframework.security.oauth2.client.userinfo.OAuth2UserRequest; import org.springframework.stereotype.Service; import java.util.Map; import java.util.Set; import java.util.HashMap; @Service public class CustomOAuth2UserService implements OAuth2UserService<OAuth2UserRequest, OAuth2User> { private final DefaultOAuth2UserService delegate = new DefaultOAuth2UserService(); @Override public OAuth2User loadUser(OAuth2UserRequest userRequest) { OAuth2User oAuth2User = delegate.loadUser(userRequest); Map<String, Object> attributes = new HashMap<>(oAuth2User.getAttributes()); // Additional processing of attributes if needed return oAuth2User; } }

Controller

Create a controller to handle login and display user info.import org.springframework.security.core.annotation.AuthenticationPrincipal; import org.springframework.security.oauth2.core.user.OAuth2User; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.GetMapping; @Controller public class LoginController { @GetMapping("/login") public String getLoginPage() { return "login"; } @GetMapping("/") public String getIndexPage(Model model, @AuthenticationPrincipal OAuth2User principal) { if (principal != null) { model.addAttribute("name", principal.getAttribute("name")); } return "index"; } }

Thymeleaf Templates

Create Thymeleaf templates for login and index pages.

src/main/resources/templates/login.html

<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org"> <head> <title>Login</title> </head> <body> <h1>Login</h1> <a href="/oauth2/authorization/facebook">Login with Facebook</a> </body> </html>

src/main/resources/templates/index.html

<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org"> <head> <title>Home</title> </head> <body> <h1>Home</h1> <div th:if="${name}"> <p>Welcome, <span th:text="${name}">User</span>!</p> </div> <div th:if="${!name}"> <p>Please <a href="/login">log in</a>.</p> </div> </body> </html>

7. Testing the Integration

Run your Spring Boot application and navigate to http://localhost:8080. Click on the "Login with Facebook" link and authenticate with your Facebook credentials. If everything is set up correctly, you should be redirected to the home page with your Facebook profile name displayed.

8. Conclusion

Integrating Facebook login into your Spring Boot application using Spring Security enhances user experience and leverages the power of OAuth2. With this setup, users can easily log in with their existing Facebook accounts, providing a seamless and secure authentication process.

Identity, authentication, anonymity; Pseudonymous identity and recovery in an uncaring world. Revision 2.1a

Identity, authentication, anonymity; Pseudonymous identity and recovery in an uncaring world. Revision 2.1a This paper explores managing identity and account recovery, going beyond multi-factor authentication (MFA) and examining the potential role of using proof of observability ledgers. The focus is on observability networks, undeniably signatures, and hard anonymity. The goal is to allow users to recover from catastrophic losses of secret keys, hardware tokens, computers, and mobile devices while still maintaining a pseudonymous identity. The paper also discusses the question of human-based secret recovery and revisits the web of trust in the age of social media. It emphasizes that the users most at risk are the ones who need the highest level of security. To achieve this, the paper proposes using secret sharing methods to create identity control blocks, understanding the difference between statutory identity and persistent global pseudonymous identity, and recognizing why this is important in the modern social context. Mitigating the risks of global identities is also discussed, and the paper proposes bootstrapping the protocol using peer-to-peer methods over existing protocols. The pitfalls of failure to scale are highlighted, and the importance of considering human factors and cryptography engineering in a combined system is emphasized. The paper suggests avoiding federated protocols to prevent monopolistic oligarchies from emerging. Since these identities are not tied to a central service they are not entrapped to a walled garden and can freely move from service to service. With operational conformance to OpenID Oauth2 and Fido U2F they can quickly be deployed to many existing services. To ensure secure key recovery, players use Shamir's secret sharing to publish a specific number of recovery key bits to a subset of peers. The reconvocation key of the primary key is also published this way. Although not all members will sign everyone's key, all group members watch the log, and groups can be of arbitrary sizes based on performance and connectedness. Players should be in multiple groups, and auto-summaries of group hashes are published to prevent rollbacks. In case a player loses their primary hardware key, they can convince N out of M of their key partners to publish their revocation token. All actions in the game use N of M fail/stop multi-party computation, and the game doesn't require a central authority or policy-setting organization since it relies on hardware tokens and published revocation and recovery keys. In practical operation the game will be designed to cause tokens to fail to simulate key loss, as well as designate some players as attackers. Each token will initially be loaded with a “Alias” and “True Name”. Attackers will have “Agent Smith” in the true name field. A play variant may be created where cheating detection by the group can force the reveal of the “True Name”.

I appear to be having some brain glitching getting in my way here tonight. And, I know that I've got some mutuals who no doubt know way more about this subject than I do. So, I thought I would go ahead and ask for some guidance over here, partly because y'all are likely to be nicer than average about it.

So, what I am trying to accomplish atm: finally get bbolli's tumblr-utils up and running locally, primarily to run personal backups. I am familiar enough with python scripting. What I have fuck all experience with thus far is OAuth.

I do know that I need to obtain my own API key, roughly how to do this, and where to paste that info in.

My major practical level wtf right at the moment is the same as this person was asking about, over 10 years ago:

That is the most relevant thing I could readily find searching. And there was nothing of direct help in replies.

On the registration page, Tumblr is asking for a couple of mandatory fields that I am not sure how to fill in, where the "application" that needs to call the API is a few personal scripts running entirely on localhost.

For that matter, I was not sure what to put in under an "Application Website:" URL, but figured that probably made less difference. It's not like this is for public consumption whatsoever, so it got a placeholder.

The only thing I could find about this in tumblr-utils documentation:

Get your personal Tumblr API key. Before June 2020, the author's API key was distributed with the source code, the then Tumblr denied access using this key. Now, each user needs to get their own key at https://www.tumblr.com/oauth/apps. Follow the instructions there; most values entered don't matter. The API key must then be copied between the single quotes in the source code at around line 105 (the line starts with API_KEY = ).

So, does it actually matter what goes into those particular fields in order to get the API key? Or should I just fill in some placeholder URLs for this particular use case? Do these instead need to refer to some script-relevant locations on localhost?

[ETA: From what I understand, the CALLBACK_URL is indeed intended so that Tumblr can call the application back during registration. I am just not sure how this is supposed to work with a local script. Same thing with the OAuth2 redirect URL called for there. What, if anything, would that be? Is it relevant here?]

As is no doubt clear by now, I have zero prior experience in this department. Feeling pretty dumb right now. And I really would appreciate it if anyone with more knowledge could offer some practical advice here.

Right now, I should probably take a little refueling break.

How to archive a Discord channel

I'm going to say this way ahead of time: this is going to be waaaaaaay more of an annoying process than it should be. Discord should allow exporting the channel history to server owners, without the need of doing all this. I won't blame you if you give up.

Get the DiscordChatExporter application to download the chat history

This program has two versions

one that has a graphical interface, but works on Windows only

one that has a command line interface, but works on Windows, Linux and macOS

This guide covers the first. The second one maybe next time, in another post. The second version also makes it easier to download every channel on the server.

Step 1: Go to here, and download the latest version in the zip file named DiscordChatExporter.zip

Step 2: Unpack the zip file

Step 3: Run DiscordChatExporter.exe

Step 4: Dismiss the scary looking warning as this will show up for any program that which developer can't afford paying $629 a year.

Step 5: Close the welcoming message and you'll see the application interface:

Prepare an access token. Do not share it to anyone else - treat it the same way as you treat your password.

There are two ways to do it:

Approach 1: use your own access token, will work with any channel you're able to access, including Direct Messages, but it is a violation of Discord Terms of Service, and therefore your Discord account could get banned for it. Use at your own risk.

Follow the instructions here, which are fairly detailed step-by-step instructions for Chrome, Firefox, and also the desktop app. I'm gonna expand more on approach 2 as I had to figure it out myself, and the current instructions for approach 2 are not really adequate enough. If you go with approach 1, skip down the entire section below, until the "Paste the token in the Token textbox and click the arrow button" section.

Approach 2: create a bot account, invite it to your server, and use its access token. This process assumes you have enough privileges to invite bots to the server ("Manage Server" permission), and therefore, but is also 100% okay as far as Discord's Terms of Service are concerned. It is also generally safer, as accidental leaking of the token will not risk you losing your user account.

Step 1: Go to the Discord developer portal.

Step 2: Create a new application by clicking the "New Application" button

Step 3: Name it however you want, I personally named it "mlemgrab". Agree to the scary sounding long ass terms of service.

Step 4: Go to the Bot section, scroll down to the "Privileged Gateway Intents"

Step 5: Enable the "Message Content Intent". We don't have to worry about the "if your bot is in more than 100 servers" part because our bot will never be in this many servers.

Step 6: Save changes by pressing the green button "Save Changes"

Step 7: Go to "OAuth2" followed by "URL Generator"

Step 8: Select the "bot" scope and then "Read Messages/View Channels" and "Read Message History" permissions

Step 9: Copy the link at the bottom and visit it:

Step 10: Press "Continue", and approve the required permissions by clicking Authorize. Once you do it, the bot account is on the server.

Step 11: Go to "Bot" and click the "Reset Token" button to get the token that will allow you to act (in our case, getting all the messages) using the bot user. If you lose that token, you can click reset again to get a new one.

Paste the token in the Token textbox and click the arrow button

Select the server, and then the channel you want to archive

Click the download button on the bottom right

Select where you want to save it, and the format. HTML is good for easy browsing and preview in a web browser, JSON is good for further processing (let's say someone else later writes a program for importing the conversation elsewhere).

For archivization purposes I recommend saving in both HTML and JSON.

Click "More" for more options.

By default the program will not download any message attachments nor avatars or emotes. If you want that, select "Download assets" option. Preferably while also selecting the "Reuse assets" option and selecting a single directory for assets if you want to archive multiple channels.

You can also select the specific time range and using the partition limit - split the archive into several files each containing N messages.

Press Export. Wait. The progress bar will move very slowly.

Once it is done, you should be able to open the HTML file with your web browser.

Treat anything on Discord as media that will be lost

Do not use Discord to host your files. Do not rely on Discord to preserve your text. DO NOT RELY ON DISCORD FOR ANY KIND OF PRESERVATION OR HOSTING!!

It CAN be lost, it WILL be lost! You must consider Discord as a part of the Core Internet, controlled by one company that hosts the servers.

I thought it was impressive at first that it replaced IRC, but now I am horrified. If the company behind Discord went under today, how many friends would you lose?

How many relationships? How much writing?

You may think this won't happen, but I remember when AIM went down and along with it, entire novels worth of interaction with my oldest friend.

IT CAN HAPPEN TO YOU. IT WILL HAPPEN AGAIN. NO COMPANY IS INFALLIBLE.

Back up your files! Download anything you've saved to Discord NOW, before the API changes go into effect! And DO NOT RELY ON THEM FOR HOLDING IMPORTANT FILES!

Essential Components of a Production Microservice Application

DevOps Automation Tools and modern practices have revolutionized how applications are designed, developed, and deployed. Microservice architecture is a preferred approach for enterprises, IT sectors, and manufacturing industries aiming to create scalable, maintainable, and resilient applications. This blog will explore the essential components of a production microservice application, ensuring it meets enterprise-grade standards.

1. API Gateway

An API Gateway acts as a single entry point for client requests. It handles routing, composition, and protocol translation, ensuring seamless communication between clients and microservices. Key features include:

Authentication and Authorization: Protect sensitive data by implementing OAuth2, OpenID Connect, or other security protocols.

Rate Limiting: Prevent overloading by throttling excessive requests.

Caching: Reduce response time by storing frequently accessed data.

Monitoring: Provide insights into traffic patterns and potential issues.

API Gateways like Kong, AWS API Gateway, or NGINX are widely used.

Mobile App Development Agency professionals often integrate API Gateways when developing scalable mobile solutions.

2. Service Registry and Discovery

Microservices need to discover each other dynamically, as their instances may scale up or down or move across servers. A service registry, like Consul, Eureka, or etcd, maintains a directory of all services and their locations. Benefits include:

Dynamic Service Discovery: Automatically update the service location.

Load Balancing: Distribute requests efficiently.

Resilience: Ensure high availability by managing service health checks.

3. Configuration Management

Centralized configuration management is vital for managing environment-specific settings, such as database credentials or API keys. Tools like Spring Cloud Config, Consul, or AWS Systems Manager Parameter Store provide features like:

Version Control: Track configuration changes.

Secure Storage: Encrypt sensitive data.

Dynamic Refresh: Update configurations without redeploying services.

4. Service Mesh

A service mesh abstracts the complexity of inter-service communication, providing advanced traffic management and security features. Popular service mesh solutions like Istio, Linkerd, or Kuma offer:

Traffic Management: Control traffic flow with features like retries, timeouts, and load balancing.

Observability: Monitor microservice interactions using distributed tracing and metrics.

Security: Encrypt communication using mTLS (Mutual TLS).

5. Containerization and Orchestration

Microservices are typically deployed in containers, which provide consistency and portability across environments. Container orchestration platforms like Kubernetes or Docker Swarm are essential for managing containerized applications. Key benefits include:

Scalability: Automatically scale services based on demand.

Self-Healing: Restart failed containers to maintain availability.

Resource Optimization: Efficiently utilize computing resources.

6. Monitoring and Observability

Ensuring the health of a production microservice application requires robust monitoring and observability. Enterprises use tools like Prometheus, Grafana, or Datadog to:

Track Metrics: Monitor CPU, memory, and other performance metrics.

Set Alerts: Notify teams of anomalies or failures.

Analyze Logs: Centralize logs for troubleshooting using ELK Stack (Elasticsearch, Logstash, Kibana) or Fluentd.

Distributed Tracing: Trace request flows across services using Jaeger or Zipkin.

Hire Android App Developers to ensure seamless integration of monitoring tools for mobile-specific services.

7. Security and Compliance

Securing a production microservice application is paramount. Enterprises should implement a multi-layered security approach, including:

Authentication and Authorization: Use protocols like OAuth2 and JWT for secure access.

Data Encryption: Encrypt data in transit (using TLS) and at rest.

Compliance Standards: Adhere to industry standards such as GDPR, HIPAA, or PCI-DSS.

Runtime Security: Employ tools like Falco or Aqua Security to detect runtime threats.

8. Continuous Integration and Continuous Deployment (CI/CD)

A robust CI/CD pipeline ensures rapid and reliable deployment of microservices. Using tools like Jenkins, GitLab CI/CD, or CircleCI enables:

Automated Testing: Run unit, integration, and end-to-end tests to catch bugs early.

Blue-Green Deployments: Minimize downtime by deploying new versions alongside old ones.

Canary Releases: Test new features on a small subset of users before full rollout.

Rollback Mechanisms: Quickly revert to a previous version in case of issues.

9. Database Management

Microservices often follow a database-per-service model to ensure loose coupling. Choosing the right database solution is critical. Considerations include:

Relational Databases: Use PostgreSQL or MySQL for structured data.

NoSQL Databases: Opt for MongoDB or Cassandra for unstructured data.

Event Sourcing: Leverage Kafka or RabbitMQ for managing event-driven architectures.

10. Resilience and Fault Tolerance

A production microservice application must handle failures gracefully to ensure seamless user experiences. Techniques include:

Circuit Breakers: Prevent cascading failures using tools like Hystrix or Resilience4j.

Retries and Timeouts: Ensure graceful recovery from temporary issues.

Bulkheads: Isolate failures to prevent them from impacting the entire system.

11. Event-Driven Architecture

Event-driven architecture improves responsiveness and scalability. Key components include:

Message Brokers: Use RabbitMQ, Kafka, or AWS SQS for asynchronous communication.

Event Streaming: Employ tools like Kafka Streams for real-time data processing.

Event Sourcing: Maintain a complete record of changes for auditing and debugging.

12. Testing and Quality Assurance

Testing in microservices is complex due to the distributed nature of the architecture. A comprehensive testing strategy should include:

Unit Tests: Verify individual service functionality.

Integration Tests: Validate inter-service communication.

Contract Testing: Ensure compatibility between service APIs.

Chaos Engineering: Test system resilience by simulating failures using tools like Gremlin or Chaos Monkey.

13. Cost Management

Optimizing costs in a microservice environment is crucial for enterprises. Considerations include:

Autoscaling: Scale services based on demand to avoid overprovisioning.

Resource Monitoring: Use tools like AWS Cost Explorer or Kubernetes Cost Management.

Right-Sizing: Adjust resources to match service needs.

Conclusion

Building a production-ready microservice application involves integrating numerous components, each playing a critical role in ensuring scalability, reliability, and maintainability. By adopting best practices and leveraging the right tools, enterprises, IT sectors, and manufacturing industries can achieve operational excellence and deliver high-quality services to their customers.

Understanding and implementing these essential components, such as DevOps Automation Tools and robust testing practices, will enable organizations to fully harness the potential of microservice architecture. Whether you are part of a Mobile App Development Agency or looking to Hire Android App Developers, staying ahead in today’s competitive digital landscape is essential.

Hey! It's been awhile since I've done a long post. Let me tell you something pretty interesting!

Do you guys know that there's a Discord bots featuring our lads in Love and Deepspace? I've been thirsty for more interactions with my Rafayel so these bots are really a heaven sent!

They are made by chaengcheekies. (https://x.com/chaengcheekies)

The creator made Rafayel, Zayne & Xavier bots. And I hope more guys will be added later!

I instantly downloaded them and been having fun interacting with them. There's a WARNING though. These are NSFW bots. lmao. So the guys will do everything they can to undress you. lol. I'm sure a lot of LaD girlies will like it! So minors, please stay away!

I uploaded here some of my interactions with them. Since I was having my lunch at that time, I'm not really in the mood to get hot and dirty with them, so I was trying my best to stop their advances. And it's kind of funny how they make a simple meal into an alluring one. lol. I wasn't able to get a meal talk with Zayne since I was a bit busy but I scheduled a date with him. hehe. And it's kind of cute.

I also like that they always listen to you. Though they are my first discord bot. I'm not really sure what the usual discord bots do, but I've been having so much fun with them.

If you are interested, go and download them now! And don't forget to thank their hardworking creator chaengcheekies!
