Freewallet, a cryptocurrency wallet provider, has been increasingly identified as a scam, defrauding thousands of customers worldwide. Despite its professional facade, numerous accounts from users reveal a pattern of deceit and fraudulent practices.
Freewallet markets itself as a good, user-friendly, multi-currency wallet. It offers a variety of services, including the ability to store, buy, and exchange cryptocurrencies. While these features appear attractive, many users have experienced significant issues that suggest fraudulent activities.
It’s a scam and we ask you never to download this app! Otherwise you will lose your coins!
Real user experiences
Many users have shared their harrowing experiences with Freewallet, highlighting the emotional and financial distress caused by the company's actions. These stories paint a picture of a systematic scam operation designed to defraud users while maintaining a veneer of legitimacy.
For example, one user described how their account was frozen after depositing a significant amount of cryptocurrency. Despite providing all requested documentation for verification, their withdrawal requests were continuously denied, and customer support ceased responding. This user eventually lost all their funds, amounting to thousands of dollars.
Another user recounted a similar experience where their account was flagged for suspicious activity immediately after making a substantial deposit. Despite having no previous issues with their account, they were unable to withdraw their funds and received no meaningful assistance from customer support.
Legal and regulatory concerns
The practices of Freewallet have attracted the attention of legal and regulatory bodies. There are ongoing discussions about the potential for collective legal action against the company. Victims are urged to document their experiences and join forces to seek justice and compensation for their losses.
Protecting yourself from scams
To avoid falling victim to similar scams, it is crucial to conduct thorough research before choosing a cryptocurrency wallet. Look for reviews and testimonials from multiple sources, and be wary of any service that demands excessive personal information or exhibits suspicious behavior.
Additionally, consider using well-established and reputable wallets that have a track record of security and reliability. Diversifying your assets across multiple wallets can also mitigate the risk of losing all your funds to a single scam.
Conclusion
Freewallet has consistently demonstrated behavior that aligns with fraudulent practices, leading to significant financial losses for many of its users. The numerous reports of account freezes, withdrawal issues, suspicious verification processes, unexplained fund losses, and poor customer support all point to a scam operation.

If the API return 404 I want my code to Throw and error, in general fetch will not throw an error on API failure with exception of a time out so I had to force that behavior:
Here is my base code
```Javascript
const response = await fetch(url);
if (!response.ok) {
if(response.status !== 404){
throw new Error(`Error on details API ${response.status}`)
}
}
```
Ok... here the solution I end up with:
```Javascript
await expect(
api.fetchEvent(body)
).rejects.toThrow('Error on details API 404');
```
It can be improved but I thought sharing the solution may help somebody else | linediconsine |
1,878,407 | Optimizing Unity Projects: Architectural Patterns and Best Practices for Scalable Game Development | Embarking on a Unity project is always an exciting journey filled with creativity and technical... | 0 | 2024-06-05T20:11:21 | https://eneaslari.com/articleview/render/optimizing-unity-projects:-architectural-patterns-and-best-practices-for-scalable-game-development-6660a068fc0f3dc55a0973f0 | unity3d, gamedev | Embarking on a Unity project is always an exciting journey filled with creativity and technical challenges. However, like many game developers, I've often found myself grappling with the complexities of organizing code and game objects. In my experience, without a solid architectural foundation, projects can quickly become tangled webs that are hard to manage and scale. This issue hit home for me during the development of my latest match-three game.
Initially, everything seemed manageable, but as the game grew, so did the complexity of its structure. New features, interactions, and game mechanics piled up, turning my well-intentioned code into a labyrinth of dependencies. It wasn't long before I found myself stuck, spending more time troubleshooting and untangling code than actually developing the game. The tipping point came when I realized that adding anything new or modifying existing features was becoming a Herculean task. It was clear that my initial approach wasn't sustainable, and I had no choice but to take a step back.
Reluctantly, I made the decision to rewrite our entire codebase—a daunting but necessary step to save the project. Throughout this challenging process, I learned just how critical it is to choose the right architecture early on. Eager to help fellow developers sidestep these issues, I began educating myself on various architectural patterns and principles. While I haven't personally tested all of these strategies, the ones I've implemented in my Unity projects have been transformative. They've not only kept my projects well-organized but have also enhanced their scalability and maintainability. Let's explore these architectural lifesavers.
### 1. **MVC (Model-View-Controller)**
- **Model**: Represents the data and business logic.
- **View**: Handles the presentation layer and user interface.
- **Controller**: Manages input and updates the model and view accordingly.
### 2. **MVVM (Model-View-ViewModel)**
- **Model**: Contains the application's data.
- **View**: Displays data and sends user commands to the ViewModel.
- **ViewModel**: Acts as a bridge between the Model and View, handling the presentation logic.
### 3. **ECS (Entity-Component-System)**
- **Entity**: Represents objects in the game.
- **Component**: Holds data related to entities.
- **System**: Contains logic that processes entities with certain components.
### 4. **Service Locator**
- Provides a centralized registry for services (like audio, input, etc.) and allows for decoupling between classes.
### 5. **Singletons**
- Ensures a class has only one instance and provides a global point of access to it. Commonly used for game managers, input managers, etc.
### 6. **Observer Pattern**
- Allows objects (observers) to be notified of changes in other objects (subjects). Useful for event systems and state changes.
### 7. **Command Pattern**
- Encapsulates a request as an object, thereby allowing for parameterization and queuing of requests.
### 1. MVC Detailed Explanation
#### Model
The Model represents the data and the business logic of your application. In a Unity context, the Model would manage the game data, rules, and behaviors independently of the user interface. It's purely about the data and its related logic.
**Example**: In a role-playing game (RPG), the Model might manage character stats, inventory items, and game mechanics like health and damage calculations.
#### View
The View is responsible for presenting data to the player and handling user interactions. Views are typically linked to Unity scenes or UI elements, displaying information to the player and sending user inputs to the Controller.
**Example**: The View could be a UI canvas displaying the player's health, inventory, and stats.
#### Controller
The Controller serves as an intermediary that manages communication between the Model and the View. It responds to user input, updating the Model as necessary, and refreshes the View when the data changes.
**Example**: When a player moves an item in their inventory, the Controller would update the Model to reflect this change and then prompt the View to update the UI display.
### 2. MVVM (Model-View-View Model)
**MVVM** stands for Model-View-ViewModel. This pattern is particularly useful for projects where you want to separate the game logic and how it's displayed, which can make it easier to manage and update your game.
- **Model**: This is where your game's data lives. Think of it as the heart of your game's rules and what happens in the game.
- **View**: This is what the players see on their screens. It might include things like health bars, menus, or the game world itself.
- **ViewModel**: This acts as a middleman between the Model and the View. It takes data from the Model and formats it so the View can display it in a user-friendly way.
**Example**: Let’s say you’re making a card game. The Model would handle the logic of the cards, such as their values and rules. The ViewModel would take this information and prepare a display like sorting the cards or highlighting playable ones. The View would then show these cards on the screen, laid out nicely for the player to interact with.
### 3. ECS (Entity-Component-System)
**ECS** stands for Entity-Component-System, and it’s a bit different from traditional object-oriented programming. It’s great for games because it helps manage lots of objects and interactions efficiently, making your game run smoother.
- **Entity**: These are the individual things in your game, like players, enemies, or items. They are just identifiers with no actual data or behavior.
- **Component**: Components are data containers attached to entities. For example, a health component might store the health value of an entity.
- **System**: Systems are where the logic is processed. They operate on entities that have specific components. For example, a movement system might handle all entities that have position and velocity components.
**Example**: In a space shooter game, your spaceship entity might have components like position, health, and weapon. Systems would read these components to move the spaceship, track and display health, and manage shooting.
### 4. Service Locator
The **Service Locator** pattern is a way to organize different services (like sound effects, data loading, etc.) in your game. It provides a single point where you can access these services without needing to know exactly how they are implemented.
**Example**: Imagine your game needs to play sound effects. Instead of each part of your game handling sound playback itself, they just tell the Service Locator, "I need to play this sound." The Service Finder then deals with the details of playing that sound.
### 5. Singletons
A **Singleton** is a design pattern used to ensure a class has only one instance and provides a global point of access to it. This is useful for things that should only exist once in a game.
**Example**: Think of a GameManager in a game, which might handle scores, player data, and game states. By making it a Singleton, you ensure there's only one GameManager being accessed globally, preventing conflicts or duplicate data.
### 6. Observer Pattern
The **Observer Pattern** is used to allow objects to observe and react to events in other objects. It’s like a subscription model where observers get notified when something they care about happens.
**Example**: In a game, you might want the UI to update when a player’s health changes. The health system can notify (or "publish") this event, and any UI elements that are observing (or "subscribed to") the player's health will automatically update.
### 7. Command Pattern
The **Command Pattern** encapsulates actions or requests as objects, allowing you to parameterize and schedule operations.
**Example**: Imagine a strategy game where you can queue up actions for your units. Each action (like move, attack, defend) can be a command object. This allows you to easily implement undo actions, delay commands, or even network commands if you’re playing online.
### Best Practices and Principles
#### **SOLID Principles**
1. **Single Responsibility Principle**: A class should have one, and only one, reason to change.
2. **Open/Closed Principle**: Classes should be open for extension but closed for modification.
3. **Liskov Substitution Principle**: Subtypes must be substitutable for their base types.
4. **Interface Segregation Principle**: No client should be forced to depend on methods it does not use.
5. **Dependency Inversion Principle**: Depend upon abstractions, not concretions.
#### **Dependency Injection**
- Promotes loose coupling by injecting dependencies rather than creating them within the classes.
### Combining Patterns
Often, the best architecture for a Unity project involves combining multiple patterns. For example, you might use MVC for UI, ECS for game object management, and singletons for core services.
### Example Architecture Setup
1. **Core**: Singleton managers (e.g., GameManager, AudioManager)
2. **Data**: Scriptable objects for game data, JSON/XML for saving/loading
3. **Presentation**: MVC or MVVM for UI management
4. **Gameplay**: ECS for managing entities and their behaviors
5. **Utilities**: Service locator for accessing services
### Implementation Tips
- **Use Unity's Scriptable Objects** for data-driven design.
- **Organize your project structure**: Separate folders for scripts, prefabs, scenes, assets, etc.
- **Use namespaces** to avoid class name conflicts.
- **Automate tasks** using Unity's built-in tools or custom editor scripts.
- **Testing**: Implement unit tests for core logic and integration tests for larger systems.
### Conclusion
Selecting the right architecture depends on the specific needs of your Unity project. A hybrid approach that combines the strengths of various patterns often works best. Regularly refactor and review your architecture to ensure it remains robust and scalable as your project grows. | eneaslari |

foreach ($words as $word) {
$wordLetterCount = array_fill(0, 26, 0);
foreach (str_split($word) as $letter) {
++$wordLetterCount[ord($letter) - ord('a')];
}
for ($i = 0; $i < 26; ++$i) {
$letterCount[$i] = min($letterCount[$i], $wordLetterCount[$i]);
}
}
$result = [];
for ($i = 0; $i < 26; ++$i) {
while ($letterCount[$i] > 0) {
$result[] = chr($i + ord('a'));
--$letterCount[$i];
}
}
return $result;
}

1,878,403 | Dive into Luxury: The Art and Science of Pool Development | Swimming pools have long been a symbol of luxury and relaxation, transforming ordinary backyards... | 0 | 2024-06-05T20:03:40 | https://dev.to/gwpservicesinc/dive-into-luxury-the-art-and-science-of-pool-development-3p2g |
Swimming pools have long been a symbol of luxury and relaxation, transforming ordinary backyards into personal oases. Today, pool development has evolved from simple rectangular designs to stunning, custom creations that blend seamlessly with a home's architecture and natural surroundings. Whether you're dreaming of a tranquil retreat or an entertainment hotspot, understanding the essentials of pool development can help you bring your vision to life.
The Initial Spark: Conceptual Design
Every great pool begins with a dream. The first step in pool development is the conceptual design phase, where homeowners and designers collaborate to outline their desires and needs. Factors like pool size, shape, and purpose are discussed, along with aesthetic preferences and budget constraints. This stage often involves sketches and 3D renderings to visualize the final product. Modern trends include infinity edges, natural rock waterfalls, and integrated spas, pushing the boundaries of traditional pool designs.
Engineering Precision: Structural Planning
Once the design is finalized, the project moves into the structural planning phase. This involves detailed engineering work to ensure the pool is safe, durable, and compliant with local building codes. Key considerations include soil testing, load-bearing assessments, and hydraulic engineering. The pool’s plumbing and electrical systems are meticulously planned to support features like heating, lighting, and water filtration systems. Advanced technologies, such as energy-efficient pumps and saltwater chlorination, are often incorporated to enhance sustainability and reduce maintenance costs.
Crafting the Canvas: Excavation and Construction
With plans in hand, the physical construction begins. Excavation transforms the landscape, carving out space for the pool’s foundation. Skilled builders then construct the pool shell using materials like concrete, fiberglass, or vinyl. Concrete is favored for its durability and flexibility in design, while fiberglass offers a quicker installation time and lower maintenance. Each material has its own benefits, and the choice largely depends on personal preference and budget.
Bringing It to Life: Finishing Touches
The final phase of pool development is where the magic truly happens. Finishing touches include tiling, coping, and the addition of aesthetic features such as mosaics or LED lighting. Surrounding landscapes are also crafted to enhance the pool area, incorporating elements like decking, patios, and greenery. Water features, such as fountains or bubblers, can add dynamic movement and soothing sounds to the environment.
Dive In: Enjoying Your Personal Oasis
Once completed, the pool is ready for enjoyment. Regular maintenance, including cleaning and chemical balancing, ensures the pool remains a safe and inviting space. Investing in a high-quality cover and automated cleaning systems can further simplify upkeep.

1,878,400 | How to Recover an Entire Folder in S3 After Accidental Deletion | Accidentally deleting an entire folder (prefix) in Amazon S3 can be a heart-stopping moment.... | 0 | 2024-06-05T19:59:44 | https://dev.to/siddhantkcode/how-to-recover-an-entire-folder-in-s3-after-accidental-deletion-173f | aws, recovery, s3, linux | Accidentally deleting an entire folder (prefix) in Amazon S3 can be a heart-stopping moment. Fortunately, if versioning is enabled on your S3 bucket, there's a straightforward way to recover your data. This blog post will guide you through restoring your deleted folder using a simple shell script.
## Prerequisite
To successfully recover your deleted folder, you must enable versioning on the target bucket. This is a critical prerequisite. If versioning was not enabled at the time of deletion, recovery isn't possible this time. However, consider enabling versioning for future protection.
For more information on enabling versioning, refer to the [AWS documentation on S3 versioning](https://docs.aws.amazon.com/AmazonS3/latest/userguide/Versioning.html).
## Recovery Method
Here is a step-by-step guide on how to recover your deleted folder:
1. **Ensure AWS CLI is installed**: You'll need the AWS Command Line Interface (CLI) to execute the recovery script. You can install it [here](https://aws.amazon.com/cli/).
2. **Create the recovery script**: Save the following script as `delete_deletemarker_of_s3.sh`.
```bash
#!/bin/bash
# Get the time one hour ago in ISO 8601 format
one_hour_ago=$(date -u -d '1 hour ago' +'%Y-%m-%dT%H:%M:%SZ')
# List all the latest delete markers
delete_markers=$(aws s3api list-object-versions --bucket my-bucket --prefix my-folder/ --query 'DeleteMarkers[?IsLatest==`true`].[Key, VersionId, LastModified]' --output text)
# Delete only the delete markers set within the last hour
while IFS=$'\t' read -r key version_id last_modified; do
if [[ "$last_modified" > "$one_hour_ago" ]]; then
echo "Deleting delete marker for $key with version ID $version_id, set at $last_modified"
aws s3api delete-object --bucket my-bucket --key "$key" --version-id "$version_id"
fi
done <<< "$delete_markers"
```
3. **Execute the recovery script**: Run the following command to execute the script.
```bash
bash delete_deletemarker_of_s3.sh
```
### Explanation of the Script
- **Get the time one hour ago**: The script calculates the time one hour prior to the current time in ISO 8601 format.
```bash
one_hour_ago=$(date -u -d '1 hour ago' +'%Y-%m-%dT%H:%M:%SZ')
```
- **List latest delete markers**: It lists all the latest delete markers for the specified bucket and prefix.
```bash
delete_markers=$(aws s3api list-object-versions --bucket my-bucket --prefix my-folder/ --query 'DeleteMarkers[?IsLatest==`true`].[Key, VersionId, LastModified]' --output text)
```
- **Delete recent delete markers**: The script iterates through the delete markers and deletes those that were set within the last hour.
```bash
while IFS=$'\t' read -r key version_id last_modified; do
if [[ "$last_modified" > "$one_hour_ago" ]]; then
echo "Deleting delete marker for $key with version ID $version_id, set at $last_modified"
aws s3api delete-object --bucket my-bucket --key "$key" --version-id "$version_id"
fi
done <<< "$delete_markers"
```
By deleting the delete markers, the script cancels the deletion, effectively restoring the deleted objects. The condition to check if the delete marker was set within the last hour ensures that only recent accidental deletions are recovered, preventing the restoration of objects that were intentionally deleted in the past.
## Running the Script in Amazon CloudShell
For ease of use, you can execute this script in Amazon CloudShell:
1. Start Amazon CloudShell from the AWS console.
2. Upload the `delete_deletemarker_of_s3.sh` file to CloudShell.
3. Run the script using the command provided above.
### Final Notes
Make sure to replace `my-bucket` with your actual bucket name and `my-folder/` with your actual folder name (prefix) in the script.
By following this guide, you can quickly recover from accidental deletions in S3, provided you have versioning enabled. If not, take this opportunity to enable versioning on your important buckets to safeguard against future accidental deletions. | siddhantkcode |

It was a nice experience filled with insights, innovations, and networking opportunities. The event, held at Stockholmsmässan, brought together thousands of tech enthusiasts, industry experts, and AWS partners, all eager to explore the latest advancements in the cloud technology from AWS.
There were more than 50 sessions and the main theme during the day was generative AI, I hope that the sessions I missed will be available on youtube soon. These were the sessions I attended:
* Keynote
* Zero Trust at Scale with Amazon Verified Permissions
* Model choice in Amazon Bedrock
* Enhance observability with insights from Amazon Bedrock
* Modernize your data lake using Open Table Formats
* Training GenAI Models on Amazon Sagemaker
Attending to these sessions was an enriching experience that left me inspired and equipped with new things to tinker with, I really hope that I will have time to explore some of the topics that were presented during the day.
If you have the opportunity to attend an AWS Summit in the future, I highly recommend it.
Until next time!

Hello everyone! So I've been developing this OSINT software for quite a long time (mostly it was in beta stage) as my first significant project, but now I feel that it is completed in most parts, so I've released that. Nevertheless, since I expect the community to use this tool (and I intended to make tool that will be appreciated and used by community), I want to hear community voice about it. So I'm asking about your feedback on some things in my project:
1. Production/Code/Design/User Interaction quality
2. Practical necessity of implemented OSINT algorithms (do you really need them in practise?)
3. Maybe some ideas on futue updates (new OSINT approaches/algorithms, QoL updates and so on)
Your opinion and feedback will be hugely appreciated!

1,878,394 | I am making my own Password Manager... | Hello everyone! I am developing a new software project in good old C++ as a side project—a... | 0 | 2024-06-05T19:41:13 | https://dev.to/drimiteros21/i-am-making-my-own-password-manager-14a7 | 
Hello everyone!
I am developing a new software project in good old C++ as a side project—a password manager designed to make your personal information more secure. I decided to create my own password manager for three main reasons:
**1.**
My research showed that many so-called trusted, paid service providers have experienced data breaches, exposing sensitive user information. Additionally, I am not comfortable sharing and storing my data online, regardless of the provider.
**2.**
Managing passwords offline is often more sophisticated. Using tools like OpenSSL, terminals, and commands to encrypt and decrypt text can be tedious, and any software that automates this process tends to lack user-friendly design and functionality.
**3.**
Creating my own password manager is fun, educational, and potentially beneficial to others. It will be easier to use and could provide passive income if others find it useful and wish to donate, as it will be available for free.
I believe many people would appreciate such a product. If you're interested, you might want to get notified when the Beta version is up. I've just finished making the landing page where you can get updates on its progress (Note: it is only optimized for desktops for now). I would love to get some honest feedback on the landing page and the product idea.

## Assumption #1: Public facing service
Self-hosted homelab was never intended to be accessible from the web. By design it is available for internal network only. It's for you. For your own personal projects. For hacking, pentesting, trying new technologies, learning. You can spin up redis, kafka, postgres with ease and learn integration with it in your home environment. You can setup rss reader, media server, password vault, etc. in your home network without access from outside world. This is the benefit of self-hosting because you can create your own tools that only you have access to.
## Assumption #2: Why not on your working PC?
For some use cases - of course, Docker Desktop is enough. Especially in case of local development environment. But the downside is that it becomes unavailable as soon as your main device is down. What if you want to have an access to your tools while your main pc is down? What if there are background jobs you want to run, or maybe you have notification bot running? The main benefit if micro-pc is that it has low power consumption of around 30 watt-hours per hour. For comparison fully-fledged stationary PC consumes between about 100-150 watt-hours per hour on light work, and laptops around 50 watt-hours per hour. That's up to 5 times difference! And that's not accounting for PC monitor!
So yeah - for something that can potentially work 24/7, it's definitely more cost-effective.
## Assumption #3: Private access
Now, let's say, you are out of home, maybe you were sent by company to a conference, or to work in different hub for a while. How do you set up remote access? Didn't I mentioned that they are not public facing services? Well, I did. But you don't have to expose your services to the web, to actually use them remotely. Please welcome VPN - the actual intended way of using them (unlike what "private vpn" services promote).
There are two solutions for VPN, and two ways to set them up. Some routers have VPN server built in, like Asus:
_This is actually screenshot from custom built firmware for Asus Router_
In case of cheaper ones, you can actually setup your VPN via docker container, and simply port-forward from router to your VPN instance.
And you can choose between **OpenVPN** and **Wireguard**, both are solid options, however Wireguard a much newer and faster than OpenVPN.
But doesn't that mean you are exposing open port to the world? Yeah, but there are ways to mitigate that:
- use fail2ban, to ban anyone on #ish attempt that fails.
- use non standard port and udp-only approach, you can avoid noobs and script kiddies this way
- use tunneling - this way you are not exposing anything, but connect via proxy to actually connect to your network. You can achieve that by yourself setting up reverse-proxy vpn on vps (now your network is just client with pass-through) or using service like [Twingate](https://www.twingate.com/)
I might cover all of that in the future, but at least I wanted to leave you something to go on on yourself.
## Assumption #4: Small number of services
Now, one of the arguments was - if you have small number of containers, you can use raspberry pi - and that's correct, but in that case wouldn't it be better to just run it on your machine? I'm talking about running more then 10-15 containers constantly. Right now, my personal server is running 27 services and counting! I'm literally replacing a lot of subscription-based productivity services with my own - all in my network.
That's what most companies do, when they ask you to connect to work VPN, most of their internal network is self hosted, and available for employees only.
Of course, I'm using raspberry pi in my own setup, but only as dns server and network intrusion detection system (nids). My NUC however, is running home assistant, wiki / notes, rss reader, media server, meal planner, automation tool, searx, password vault and task/project tracker, among others. And the best thing is - because it's all on docker, I'm not even using that much resources I would with VPS or VM. Here's proof:
CPU utilization at ~15%
RAM utilization at ~32%
SSD utilization at ~10%
And this is number of apps exposed to my network. It does not count for dependencies. So as you can see, you don't need strong CPU for something like that. Simple i3 2-core 4-thread CPU is enough. What you need is RAM. I have 32 GB of DDR4, and I'm using only 1/3 of it, but as my infrastructure grows I might need an upgrade... maybe... or maybe not.
It all depends on use case.
## Assumption #5: Why not cloud? Why not RACK?
Now you might ask, why not spin up AWS EC2 if CPU is not that demanding? Well let's keep in mind, that what containers uses the most is RAM. For my current setup I would need about 12-16 GB RAM instance. Currently only R6G Large fulfill that demands which equals to $80 monthly which is $960 yearly. For that amount of money you can buy both NUC and NAS which will collectively exceed what AWS has to offer and stay with you for years!
RACK on the other hand is really fun project to have, but it's way more expensive one, takes up a lot more space, and consumes more energy. So if you are about cost-cutting, that's not the most cost-effective option.
## Practical use cases
Now that we tackled most of the assumptions, let's discuss who actually benefits such setup.
### Use Case #1: Startups and small business
Having a small on-premise pc, that runs business infrastructure is a blessing, granted you have at least one person that know how to maintain it. It means that you can set up your infrastructure according to your employees needs. There are a ton of tools that helps running a business and doesn't cost a dime if you host them yourself, starting on LDAP, and ending with CRM.
### Use Case #2: Network Nerds
I don't even have to mention it in this case right? Chances are you already have one. Don't confuse with "networking" during IT conference.
You own a homelab to play with infra. You create virtual networks, set up credentials, firewalls and policies. You are basically refining your skills as IT guy, because you like it.
### Use Case #3: Penetration Testers
Homelab is great environment to actually deploy vulnerable apps and OS, to try and hack into them. Yeah sure, there are sites like hackthebox that provide that experience, but if you want to see ransomeware running wild, VM or container are safe environment for that.
### Use Case #4: DevSecOps
Now, I don't have to explain docker containers for you. But kubernetes on the other hand, is a different story, and with homelab you can test deployment script for cheap. And I know, probably like some of you I tested kubernetes on VM stack, and was not impressed. Well, let me tell you that there is such thing like kubernetes in docker (kind), and it runs 100x better on vm-less machine than vm stack!
### Use Case #5: Cloud Native Developers
Basically same category as DevSecOps. You might put Openstack or Rancher on top of your infra. Or you might add Gitlab to keep your repos private with additional CI/CD pipeline to deploy locally. It makes total sense if you want your apps available internally. After all it's part of the fun.
### Use Case #6: Automation, Media Server, Documents and News Hosting.
And the final case is almost simply "others". You can set up Home Assistant, N8N, Plex/Jellyfin, Paperless. All of that are convenience software. It's just helps to organize your life better and automate a bunch of staff. It also works great with smart homes, when you have local network enabled devices, like lights, air conditioning, blinders. You don't need fancy service to set up your smart home, you can do it yourself one bit at a time. Granted, if you only have only couple of services, newest raspberry pi might be more then enough.
## Upsides and downsides
Of course running homelab has it's upsides and downsides. It's not for everyone. For me, opportunity to learn and shear fun of setting it up outshines the frustration of maintaining it. But let me recap some pros and cons:
Pros:
+ Your personal network, hidden behind the curtain
+ Full control over what's in the
+ Free open-source stuff
+ Fun way to improve your skills and learn
+ Depending on setup you can cut quite a lot of monthly costs
Cons:
- Steep initial cost
- Takes quite some time to set up
- Requires above average technical skills
- Adds up to your electricity bill
- Requires regular semi-maintenance
## Summary
The number of use cases for homelab might not be that big and for many it might not be convenient to maintain it themselves. With using third party, you often pay for exactly that: convenience. However if you are into this stuff, you don't have to use your homelab for exactly one use case. You can mix and match according to your needs. And that's the beauty of homelab - flexibility. That's why I chose to run mine. For every paid service I might need at the moment, there is an open source version, that I might be able to run myself. And for everything that is client-facing - I will use AWS. | sein_digital |

1,878,384 | Whales Betting on XRP Returns Amidst Coin’s Downsiding Performance | Whales rack $299 million worth of XRP in 24 hours while the coin keeps marking mixed signals... | 0 | 2024-06-05T19:18:40 | https://dev.to/endeo/whales-betting-on-xrp-returns-amidst-coins-downsiding-performance-553e | webdev, javascript, web3, blockchain | ## Whales rack $299 million worth of XRP in 24 hours while the coin keeps marking mixed signals in the chart
While Ripple (XRP) has been keeping up with a sluggish market performance, staying within a stagnating liquidity range, it has surprisingly experienced a boost in whale activity.
Will investors’ fondness of XRP move out the writing on the wall for the coin? The question remains open as we dive into Ripple’s on-chain dynamics.
## Derivatives Market Indicate Controversy
On-chain data for Ripple (XRP) derivatives presents a mixed picture.
Regardless of a dubious price movement, XRP has indicated a dramatic surge in Open Interest rate and a spike in trading volume, marking the increased investment interest.
By contrast, XRP netflows have been recording a strong downsurge for the last 4 months, indicating no correlation with Ripple’s price movements.
Despite the bearish sentiment in the market, data from Whale Alert revealed that whales are stacking on XRP, acquiring nearly $300 million in XRP in the last 24 hours.
What is more, XRP demonstrated a sharp uptick in Social Dominance. Still, the community’s waning interest, as reflected in declining social volumes, could be a response to its ongoing performance issues, indicating a cooling off in investor sentiment towards Ripple.
The regressed Social Interest correlates with a recent Brad Garlinghouse’s statement, which cited that Ripple’s previously rumoured Initial Public Offering (IPO) is at low likeability, given the company’s legal disputes with the U.S. Securities and Exchange Commission (SEC).
Ripple’s CEO pointed out that Ripple’s S-1 registration statement for an IPO requires SEC approval, yet he doubts a favourable outcome.
> “Going public in the United States for Ripple right now doesn’t make any sense,” he went on.
## Silver Lining for a Breakout
As the fundamental factors indicate strong controversy, chart readings have foot in both camps as well.
A closer look at the 1-day chart confirms that XRP’s price has been confined within a critical range, bounded by a key resistance at $0.55 and crucial support at $0.47, leading to prolonged sideways price actions.
The pattern resembles Ripple’s moves from August to November 2023, before Ripple embarked on an impulsive bullish surge toward the $0.73 resistance, reclaiming the 100-day and 200-day moving averages (MA). Given that XRP is indicating similar dynamics at the writing time, a lasting upward trend might develop if buyers break past the critical zone.
Still, as per the fundamental factors and the robust bullish pressure, the continuous rejections suits as a more realistic option in the near term.
The 4-hour chart proves the sentiment, marking low volatility and muted price action. XRP’s price has reached a narrow range, bounded by the 0.5 ($0.5310) Fibonacci level and the ascending wedge’s lower boundary at $0.51.
A break below the pattern’s lower trendline could lead to a bearish retracement towards the static support at $0.48.
Conversely, if buyers breach the 0.5 Fibonacci level, the next target will be the 0.618 ($0.5574) Fibonacci level in the short term.
While Ripple (XRP) remains a highly controversial asset per its local market dynamics, whales’ optimism may hint at its potential breakout.
Specifically, a break below support levels may confirm a bearish trajectory for XRP, yet a push above the moving averages will signal a bullish sentiment. | endeo |

This guide will be divided into three parts to provide a detailed overview, setup instructions, use cases, and real-world examples.
###Introduction to ScrapeGraphAI and Setup
**Overview:**
ScrapeGraphAI stands out in the data-intensive digital landscape by integrating LLMs and modular graph-based pipelines. This library automates the scraping of data from various sources like websites and local files (XML, HTML, JSON, etc.).

Finally, confirmation has arrived that the film is officially in development, with acclaimed actor Cillian Murphy signed on to reprise his iconic role as Tommy Shelby.
June 5 (UPI) — Cillian Murphy will once again take on the role of Tommy Shelby in an upcoming Peaky Blinders film.
The 48-year-old actor is set to star in the new movie, which will be available on Netflix.
Netflix announced this news on Tuesday, sharing a photo of the film’s script. The screenplay is written by Steven Knight, the creator of Peaky Blinders, and will be directed by Tom Harper, who directed the show’s first season.
“It seems like Tommy Shelby wasn’t finished with me… It is very gratifying to be recollaborating with Steven Knight and Tom Harper on the film version of Peaky Blinders. This is one for the fans,” Murphy said in a statement.
Peaky Blinders ran for six seasons on BBC Two and BBC One from 2013 to 2022 and was also available on Netflix.
The British drama series followed the Shelby family and their Peaky Blinders gang, chronicling their lives from 1919 to 1934 as they dealt with dramatic social, economic, and political changes.
The initial cast of Peaky Blinders included Cillian Murphy, the late Helen McCrory, Paul Anderson, Sophie Rundle, Ned Dennehy, Benjamin Zephaniah, Tom Hardy, Finn Cole, and Natasha O’Keeffe.
In an interview with Netflix’s Tudum, Steven Knight revealed that the upcoming film will explore a fresh, “explosive chapter in the Peaky Blinders saga.”
“No holds barred. Full on Peaky Blinders at war,” Knight expressed.
Filming for the Peaky Blinders movie is scheduled to commence later this year.

1,878,379 | Leveraging Agenda.js for Efficient Email Scheduling in Node.js Backend | Introduction In the realm of backend development with Node.js, efficiently managing... | 0 | 2024-06-05T19:07:35 | https://dev.to/haider_zubairi_/leveraging-agendajs-for-efficient-email-scheduling-in-nodejs-backend-19k1 | node, learning, database, webdev | ## Introduction
In the realm of backend development with Node.js, efficiently managing asynchronous tasks is crucial for maintaining application robustness and responsiveness. Node.js thrives on handling many requests concurrently, but long-running asynchronous operations (like database calls or network requests) can block the main thread, hindering responsiveness. This is where _background jobs_ come in.
[Agenda](https://www.npmjs.com/package/agenda) , a powerful MongoDB-based job scheduling library, excels at managing these background jobs. It allows you to schedule tasks to run asynchronously in the background, freeing up the main thread to handle user requests promptly. This article focuses on how to set up and configure Agenda in a Node.js backend to schedule email reminders. Sending email reminders is a perfect example of how Agenda.js can streamline these asynchronous background processes.
## Understanding Agenda
Agenda.js is a flexible job scheduling library for Node.js, designed to work seamlessly with MongoDB. It allows developers to define, schedule, and manage jobs, making it an excellent choice for tasks such as email reminders, data processing, and more.
## Setting Up Agenda.js
Let's start by integrating Agenda.js into our Node.js backend.
## Step 1:Install Agenda.js
```
npm install agenda
```
## Step 2: Configure Agenda.js
Next, configure Agenda.js to connect to your MongoDB instance. Create a file named connect.js for this configuration
```
const { Agenda } = require('agenda');
const { MongoClient, ServerApiVersion } = require('mongodb');
// Configure Agenda
const agenda = new Agenda({
db: { address: "mongodb+srv://<YOUR_MONGO_USERNAME>:<YOUR_MONGO_PASSWORD>@cluster0.mongodb.net/<YOUR_DATABASE_NAME>?retryWrites=true&w=majority", collection: 'agendaJobs' },
});
async function connectToMongoDB() {
const uri = "mongodb+srv://<YOUR_MONGO_USERNAME>:<YOUR_MONGO_PASSWORD>@cluster0.mongodb.net/<YOUR_DATABASE_NAME>?retryWrites=true&w=majority";
const client = new MongoClient(uri, {
serverApi: {
version: ServerApiVersion.v1,
strict: true,
deprecationErrors: true,
}
});
try {
await client.connect();
await client.db("admin").command({ ping: 1 });
console.log("Connected to MongoDB!");
return client;
} catch (err) {
console.error(`Error connecting to MongoDB: ${err}\n`);
throw err;
}
}
module.exports = { connectToMongoDB, agenda };
```
Replace YOUR_MONGO_USERNAME, YOUR_MONGO_PASSWORD, and YOUR_DATABASE_NAME with your actual MongoDB credentials and database name.
## Defining and Scheduling Jobs with Agenda.js:
Now, let's define a job in Agenda.js and schedule it. In this example, we will schedule an email reminder.
## Step 3: Define the Job
Define the job that sends an email reminder. Add the following code to your main application file or create a new file for handling tasks:
```
const { ObjectId } = require('mongodb');
const nodemailer = require('nodemailer');
const { agenda, connectToMongoDB } = require('./connect');
require('dotenv').config();
// Define the 'sendEmail' job
agenda.define('sendEmail', async (job) => {
const { toSender, email_subject, messageContent } = job.attrs.data;
try {
const transporter = nodemailer.createTransport({
host: "smtp.gmail.com",
port: 587,
secure: false,
auth: {
user: process.env.EMAIL_USERNAME,
pass: process.env.EMAIL_PASSWORD,
},
tls: {
rejectUnauthorized: false,
},
});
const message = {
to: toSender,
subject: email_subject,
html: messageContent
};
await transporter.sendMail(message);
console.log("Email sent successfully");
} catch (error) {
console.error('Error sending email:', error);
throw new Error("Email could not be sent");
}
});
```
Update process.env.EMAIL_USERNAME, process.env.EMAIL_PASSWORD, and the database name in connectToMongoDB to match your configuration.
## Step 4: Schedule the Job
Create a function to schedule the email reminder job when a new task is added. Here’s an example function for adding a task and scheduling the email:
```
async function addTask(req, res) {
const { taskTitle, endDatetime, taskDescription, creationTime, taskStatus } = req.body;
let client;
try {
client = await connectToMongoDB();
const database = client.db('<YOUR_DATABASE_NAME>'); // Update this to match your database name
const tasksCollection = database.collection('<YOUR_COLLECTION_NAME>'); // Update this to match your collection name
await tasksCollection.insertOne({
taskTitle,
taskDescription,
endDatetime,
creationTime,
taskStatus,
});
// Schedule the email reminder
await agenda.schedule(new Date(endDatetime), 'sendEmail', {
toSender: "<RECIPIENT_EMAIL_ADDRESS>", // Update this to the actual recipient's email address
email_subject: 'Task Reminder',
messageContent: 'This is a reminder for your task.',
});
res.json({ status: true, message: 'Task created and email reminder scheduled' });
} catch (error) {
console.error('Error adding task:', error);
res.json({ status: false, message: 'An error occurred while adding the task' });
} finally {
await client.close();
}
}
module.exports = { addTask };
```
Note: Update **_RECIPIENT_EMAIL_ADDRESS_**, **_YOUR_DATABASE_NAME_**, and **_YOUR_COLLECTION_NAME_**to match your configuration.
## Conclusion
By integrating Agenda.js into your Node.js backend, you can efficiently manage and schedule tasks, such as sending email reminders. Agenda.js's seamless integration with MongoDB makes it a powerful tool for handling asynchronous operations, enhancing both application functionality and user experience.

1,878,378 | Understanding Version Control Systems | What is a Version Control System? Version control systems (VCS) are essential tools for managing... | 0 | 2024-06-05T19:04:25 | https://dev.to/gous_sayyad/understanding-version-control-systems-1bj8 | git, github, awscommunity, devops | **What is a Version Control System?**
Version control systems (VCS) are essential tools for managing changes to files over time. They record modifications, allowing teams to track changes in code and collaborate efficiently.
**Why Are Version Control Systems Important?**
In software development, teams often work from different locations, each contributing to various functionalities. Developers modify the source code, either by adding or removing parts. A version control system enables teams to manage these changes seamlessly, recording who made what changes and when. Contributors work on separate branches, and changes are only merged into the main codebase after thorough review. This approach not only keeps the source code organized but also enhances productivity by streamlining the development process.
Imagine a scenario where new functionalities are added to an application but the updated version has issues. Since the VCS tracks all changes, you can revert to a previous version and continue working, avoiding the new bugs.
**Benefits of Version Control Systems
Enhanced Collaboration:** Speeds up development by enabling efficient teamwork.
**Increased Productivity:** Improves communication and support, expediting product delivery.
**Error Reduction:** Tracks every change, reducing errors and conflicts.
**Remote Work:** Allows contributors to work from any location.
**Isolated Changes:** Each contributor's changes are isolated until validated and merged.
**Disaster Recovery:** Helps in recovering from any mishaps.
**Detailed Tracking:** Records who made changes, what changes were made, and why.
**How Version Control Systems Work
Repository:** A database of changes, containing all edits and historical versions.
**Copy of Work (Checkout):** A personal copy of all files in a project, which you can edit independently. Once done, you commit changes to the repository.
**Team Collaboration:** In a team setting, you can’t directly alter the main code in production. VCS allows you to merge changes without disrupting the live system. You can test functionalities locally and only merge them back once they’re verified.
**Types of Version Control Systems
Local Version Control Systems**
Simplest form, storing changes on a local database.
**Example:** RCS, which keeps patch sets (differences between files).
Centralized Version Control Systems (CVCS)
Single global repository.
Users must commit changes to the central repository for others to see them.
**Benefits:** Enhanced collaboration and control.
**Downsides:** Single point of failure—if the central repository goes down, collaboration halts.
**Distributed Version Control Systems (DVCS)
**
Multiple repositories; each user has their own repository and working copy.
Changes are committed locally and must be pushed to a central repository for others to see.
**Benefits:** No single point of failure. Examples include Git and Mercurial.
**Purpose of Version Control**
**Simultaneous Work: **Multiple team members can work on a project concurrently.
**Multiple Devices: **Allows individuals to work on different computers.
**Integrated Work:** Combines simultaneous work from different team members, requesting human assistance for conflicting edits.
**Historical Access:** Provides access to previous versions, safeguarding against data loss. Mistakes can be undone without losing ongoing work. It also offers insights into who made changes and why.

1,878,376 | Pedaling Through Data: A Wheelie Fun Bike Rental Analysis with Python and PostgreSQL | Introduction Hey everyone! Ever wondered how weather affects bike rentals in the city?... | 0 | 2024-06-05T19:00:46 | https://dev.to/jampamatos/pedaling-through-data-a-wheelie-fun-bike-rental-analysis-with-python-and-postgresql-13dc | python, postgres, datascience, sql | ## Introduction
Hey everyone!
Ever wondered how weather affects bike rentals in the city? Well, [Codecademy](https://www.codecademy.com) did too! As part of their Data Engineering Course, they handed me some data and said, "Analyze this!" So, I grabbed my Python, Jupyter Notebook, and PostgreSQL, and embarked on a data adventure to uncover the secrets of bike rental patterns.
In this post, I'll walk you through the process, share some cool insights, and maybe even crack a few jokes along the way. So, grab your helmet, and let's ride through this data journey together!
### Data Preparation
First things first, let's talk data. For this project, Codecademy provided two datasets:
- **Citi Bike ridership data:** This gives us the lowdown on when and where people are riding those snazzy blue bikes.
- **NOAA weather data:** Because we need to know if it's raining cats and dogs or if it's sunny and perfect for a ride.
Cleaning and transforming the data is like tuning up your bike – it's gotta be done before you hit the road. Here are some highlights of what I did:
- **Dealt with missing values:** Because incomplete data is like riding a bike with a flat tire.
- **Merged the datasets:** Think of it as combining the best parts of two bikes into one super-bike.
- **Formatted columns:** Making sure dates look like dates and not some weird alien language.
Here's a snippet of the code that got the job done (you can check out the entire code at the [GitHub repository](https://github.com/jampamatos/codecademy_stuff/tree/main/Data/bike_rental) :
```python
import pandas as pd
# Load the datasets
bike_data = pd.read_csv('citi_bike_data.csv')
weather_data = pd.read_csv('weather_data.csv')
# Handle missing values
bike_data.fillna(0, inplace=True)
weather_data.fillna(method='ffill', inplace=True)
# Merge datasets on the date column
merged_data = pd.merge(bike_data, weather_data, on='date')
# Format columns
merged_data['date'] = pd.to_datetime(merged_data['date'])
```
With the data prepped and ready, it was time to create the backbone of our analysis – the PostgreSQL database.
### Setting Up PostgreSQL
Building a database schema is like designing the perfect bike frame – it needs to be sturdy and efficient. Here's the lowdown on how I set up my PostgreSQL database:
- **Tables:** Created tables for bike rentals and weather data.
- **Relationships:** Linked the tables on the date column because it's all about timing!
Here's a sneak peek at the SQL code for creating the tables:
```sql
CREATE TABLE bike_rentals (
ride_id SERIAL PRIMARY KEY,
date DATE,
start_station VARCHAR(100),
end_station VARCHAR(100),
user_type VARCHAR(50)
);
CREATE TABLE weather (
weather_id SERIAL PRIMARY KEY,
date DATE,
temperature FLOAT,
precipitation FLOAT,
snowfall FLOAT
);
```
After setting up the tables, I inserted the cleaned data into PostgreSQL. Smooth sailing so far!
### Data Analysis
Now comes the fun part – analyzing the data! WiGitHub repositoryth our PostgreSQL database set up, it was time to dig into the data and uncover some insights. Here are the key questions we aimed to answer:
1. How does weather affect the number of bike rentals?
2. Are there specific weather conditions that lead to a spike or drop in bike rentals?
To tackle these questions, I used SQL to query the database and visualize the results with Python. Here’s an example of one of the SQL queries I used:
```sql
SELECT
br.date,
br.user_type,
COUNT(br.ride_id) AS trip_count,
w.temperature,
w.precipitation
FROM
bike_rentals br
JOIN
weather w ON br.date = w.date
GROUP BY
br.date, br.user_type, w.temperature, w.precipitation
ORDER BY
br.date;
```
This query gave us a detailed view of bike rentals per day, categorized by user type and correlated with temperature and precipitation.
### Results and Discussion
Here are some of the cool insights we uncovered:
- **Temperature vs. Bike Rentals:** Warmer days see more bike rentals. No surprises there! Who doesn't love a sunny ride?
- **Precipitation vs. Bike Rentals:** Rainy days? Not so much. Bike rentals drop significantly when it’s raining.
Here’s a visualization of the temperature vs. trip counts:
```python
import matplotlib.pyplot as plt
# Sample data for plotting
temperature = merged_data['temperature']
trip_counts = merged_data['trip_count']
plt.scatter(temperature, trip_counts)
plt.title('Temperature vs. Bike Rentals')
plt.xlabel('Temperature (°C)')
plt.ylabel('Trip Counts')
plt.show()
```
And another one for precipitation:
```python
precipitation = merged_data['precipitation']
plt.scatter(precipitation, trip_counts)
plt.title('Precipitation vs. Bike Rentals')
plt.xlabel('Precipitation (mm)')
plt.ylabel('Trip Counts')
plt.show()
```
As expected, there’s a strong positive correlation between warm weather and bike rentals. On the flip side, rain is a big no-no for bike enthusiasts.
### Conclusion
This project was a blast to work on and gave me some great insights into how weather affects bike rentals. It was a perfect blend of data cleaning, database management, and analysis – all while pedaling through Codecademy's Data Engineering Course.
If you have any thoughts, suggestions, or just want to share your own bike rental stories, drop a comment below! Let's keep the conversation rolling.
### Code and Data
You can check out the complete code and datasets on my [GitHub repository](https://github.com/jampamatos/codecademy_stuff/tree/main/Data/bike_rental). Feel free to fork it, play around with the data, and maybe even come up with your own insights.

Learning in public is grand, and when you have a team that is willing to help with something that seems simple, but you fall into overthink for the wrong items, it can really help to type out your thoughts, actions, and what the program does to frustrate you. And in this case, getting a value I could see in the debugger was the issue
The automation needs to check for page elements – and the drop-down selector triggers potentially different elements. Plus, depending on the user logged in, there may well be different options available in that drop-down. Then, I can get the options available for the user on the drop down, get their values, cycle through them, and verify each set of elements on the page.
My test account for this has four options on the drop-down, so I budgeted a couple of hours to get each step done. Getting the contract was somewhat easy: the drop-down is a select element, so QuerySelectorAllAsync() with option as the items I wanted to get was only slightly frustrating. I think this is my first time working with IElementHandles, but if they are all this easy, then I’m good! I had hard-coded a specific option for a previous test, so I knew the information I needed. And to make sure, I checked with that hard-coded information – and yes, this works!
Well, I THOUGHT I was good – to make sure I had the correct information (we had just updated the certificate, so there was a better option for connecting to the environment) I added extra items to the drop-down for the test account. Being newer to C Sharp, I didn’t know what effect the change would have, but wanted to make very sure that the information I had returned was correct! It turned out that one of the changes updated the SqlConnectionString I’m using: I was pulling from the wrong environment! One of the developers kindly took the time to look at my code, and to verify that it was correct. We kept looking, and they checked the connection string. That turned out to be the issue, and thankfully, it was a simple correction I could do without having to ask for assistance. I did ask, then figured it out while waiting for the meeting to start.
Step 1 is done: I can access the correct data. Getting the user information was a more-familiar process for me. This is a “match the email to the user ID” call and assign it to a variable. I’m doing these tests in small steps, and this will be used many times. I decided to keep the code a bit cleaner. There are going to be several methods that access user-specific information, so they are going to be tucked away in their own class. It will make future code-reading easier, and hopefully more organized.
I now know my user’s id, and the drop-down options that are available. It’s time for the one I’m hoping will be easy: cycling through the options. I knew a foreach loop was a decent choice for now. It may not be the correct choice longer-term, but I’m approaching this with the “Make it work, then make it pretty” attitude. And the system complained at me. It wanted to know what would happen if the selectors were null. And this was a reasonable thing, but I wanted to complete the task! So off to a rabbit hole of “how to do a null check”. This turned out to be a simple one-line update that would use the data and to use a hard-coded value that was a default option if there happened to be no data (and an urgent log message to be sent!).
Some research, and it seems that EvaluateAsync(value => value.textContent should give me the information I need! And it didn’t. Running it with the debugger (and a break point on the next line) shows that it gives me the text shown in the drop-down, but not the value. Looking at what’s evaluated shows that it’s doing what I asked. Now to figure out how to get it to do what I want! I can see the value in the debugger, under preview – now how to get it?
Some research into JSHandle@ showed me yet another area I need to focus on for skilling up. And several other attempts to get the correct information. It’s been a generous 45 minutes: it’s time to ask for help, again. A different one of the developers has a few moments, and I see the typing indicator. It’s almost at the point that I worry.
It seems that a lambda is used to be able to input more-complex functions – something that one of the team was not familiar with. But, as I suspected, I was using the wrong value types to get the correct answer. A quick change to select => select.value got me the information I needed!
Now to get the rest of the section to accept this information. The original hard-coded statement had that value, including the semicolon, in the statement. Using it as a variable, the system is complaining about the semicolon. I’m going to try and use Regex to get the value before the semicolon, and input that. But first, I think another cup of coffee is called for.
I’m not happy with how I’m coding this, and the coffee helped. I have two lambdas being passed, so I’m going to try and combine them, and see it things will work. And so far, it looks promising. And it worked! Other than my foreach loop, but that’s a problem for another session. | arleneandrews |
1,877,719 | Automatically remove automatic IPv4 address assignment to Amazon EC2 instances | It is now possible to dynamically remove and add public IPv4 addresses that were recently... | 0 | 2024-06-05T18:49:42 | https://dev.to/nishikawaakira/automatically-remove-automatic-ipv4-address-assignment-to-amazon-ec2-instances-12fl | aws | It is now possible to dynamically remove and add public IPv4 addresses that were recently automatically assigned to an EC2 instance.
[](https://aws.amazon.com/about-aws/whats-new/2024/04/removing-adding-auto-assigned-public-ipv4-address/)
Accordingly, this article will try to automatically delete the public IPv4 address that was assigned to EC2 by default.
## Configuration
This time, I used the configuration AWS Config -> Amazon EventBridge -> AWS Lambda. Actually, AWS Config -> AWS Systems Manager can also be configured using Automation runbook, which is smarter, but this time I would like to introduce the method using AWS Lambda.
## Configure AWS Config
First, configure AWS Config." [ec2-instance-no-public-ip](https://docs.aws.amazon.com/config/latest/developerguide/ec2-instance-no-public-ip.html)". This managed rule, however, does not enable evaluation of provisioned resources. However, the evaluation mode of this managed rule enables evaluation of provisioned resources, and evaluation is performed only after the instance is started. Therefore, if you want to modify it at startup, you need to prepare your own rules. On the other hand, if you want to target EC2 after startup, this rule may be suitable.
That's all there is to AWS Config. It is very easy.
## Create AWS Lambda
In fact, here is where I run into a bit of a snag. In this case, I have chosen Python, but in general, if you want to use Python in Lambda to execute APIs, you will need to use a library called Boto3. Lambda comes standard with this library, but if the API specification has just been changed, as in this case, Boto3 is not supported, or the version of Boto3 in Lambda itself is a bit old, and an error will occur.
[API Specification](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_ModifyNetworkInterfaceAttribute.html) and send a request as follows,
Unknown parameter in input: "AssociatePublicIpAddress"
You may see that you have been told, "Unknown parameter in input: "AssociatePublicIpAddress".
So, let's first find out how many versions of Boto3 Lambda has.
Let's run the following in Lambda.
When I ran this, it showed 1.34.42 (as of 5/14/2024).
However, the latest version of Boto3 at this time is 1.34.103. And I see that the ability to dynamically remove and add auto-assigned public IPv4 addresses for this EC2 instance was added in 1.34.91.
I found that it is not possible to run the application as it is, so we need to create a Lambda Layer.
Incidentally, as a side note, the same results were obtained when making API calls with YAML in Systems Manager, so it seems that Systems Manager also takes some time to catch up with the latest API.
So, keep in mind that you will need to wait a few days after a new specification is implemented.
I will not discuss how to create the Lambda Layer, but once it has been created, implement it as follows.
```
import json
import boto3
def modify_network_interface_attribute(network_interface_id):
ec2 = boto3.client('ec2')
try:
response = ec2.modify_network_interface_attribute(
NetworkInterfaceId=network_interface_id, # Specify the target Network Interface ID.
AssociatePublicIpAddress=False # False deletes the public IPv4 address
)
print("Network Interface Modified Successfully:")
print(response)
except Exception as e:
print("An error occurred:", e)
def lambda_handler(event, context):
detail = event['detail']
# network_interface_id = detail['configurationItem']['configuration']['networkInterfaceId']
network_interface_ids = []
# Get a list of resources that have changed
result = detail.get('newEvaluationResult')
identifier = result.get('evaluationResultIdentifier')
configuration_item = identifier.get('evaluationResultQualifier')
# Check if the resource type is an EC2 instance
if configuration_item and configuration_item['resourceType'] == 'AWS::EC2::Instance':
instance_id = configuration_item['resourceId']
ec2_client = boto3.client('ec2')
# Get instance details
response = ec2_client.describe_instances(InstanceIds=[instance_id])
reservations = response['Reservations']
# Stop auto-assign of all network interface IDs
for reservation in reservations:
for instance in reservation['Instances']:
for interface in instance['NetworkInterfaces']:
network_interface_ids.append(interface['NetworkInterfaceId'])
modify_network_interface_attribute(interface['NetworkInterfaceId'])
print("Network Interface IDs: ", network_interface_ids)
return {
'statusCode': 200,
'body': json.dumps('Success!!')
}
```
It is written in a rather crude manner and returns, "Success! but if you just want to remove the public IP address automatically, you can do it with this.
## Testing AWS Lambda
The following can be used for testing. Please enter the instance ID you have set up appropriately in resourceId, and then run the test.
```
{
"version": "0",
"id": "ID",
"detail-type": "Config Rules Compliance Change",
"source": "aws.config",
"account": "[AWS Account ID]",
"time": "2024-05-19T12:19:54Z",
"region": "ap-northeast-1",
"resources": [],
"detail": {
"resourceId": "[Instance ID]",
"awsRegion": "ap-northeast-1",
"awsAccountId": "[AWS Account ID]",
"configRuleName": "ec2-instance-no-public-ip",
"recordVersion": "1.0",
"configRuleARN": "arn:aws:config:ap-northeast-1:[AWS Account ID]:config-rule/config-rule-qx4cpe",
"messageType": "ComplianceChangeNotification",
"newEvaluationResult": {
"evaluationResultIdentifier": {
"evaluationResultQualifier": {
"configRuleName": "ec2-instance-no-public-ip",
"resourceType": "AWS::EC2::Instance",
"resourceId": "[Instance ID]",
"evaluationMode": "DETECTIVE"
},
"orderingTimestamp": "2024-05-19T00:03:43.749Z"
},
"complianceType": "NON_COMPLIANT",
"resultRecordedTime": "2024-05-19T12:19:53.922Z",
"configRuleInvokedTime": "2024-05-19T12:19:53.696Z",
"annotation": "This Amazon EC2 Instance uses a public IP."
},
"notificationCreationTime": "2024-05-19T12:19:54.417Z",
"resourceType": "AWS::EC2::Instance"
}
}
```
If it works correctly, the configuration of the instance in question should change as follows.
## Configure Amazon Event Bridge
Finally, let's create the rules for EventBridge.
The event pattern is as follows AWS Config is the source and calls Lambda based on Compliance Change for ec2-instance-no-public-ip.
```
{
"source": ["aws.config"],
"detail-type": ["Config Rules Compliance Change"],
"detail": {
"configRuleName": ["ec2-instance-no-public-ip"]
}
}
```
Select AWS Lambda function in Target and select AWS Lambda function you just created.
All that remains is to create another instance and confirm that the modifications have been made automatically.
You may want to monitor it to make sure it is working properly.
If it is not working properly, try logging in AWS Lambda function and debugging to see if the Lambda itself is being called properly.
## Conclusion
I was able to remove the public IP from EC2 more easily than I expected, but it is not as simple as using AWS Systems Manager Automation runbook (my own subjective opinion), and requires a fair amount of coding knowledge. I'm writing roughly again this time, but we should also pick up error cases more thoroughly, and we need to pay attention to such things.
Next time, I would like to do the same assignment to see how it can be written using AWS Systems Manager Automation runbook. | nishikawaakira |

2. **Crie e configure um transporter**: Um transporter é a base para o envio de emails com Nodemailer. Ele define o serviço de email a ser usado e as credenciais necessárias.
```javascript
const nodemailer = require('nodemailer');
let transporter = nodemailer.createTransport({
service: 'gmail',
auth: {
user: 'seu-email@gmail.com',
pass: 'sua-senha'
}
});
```
3. **Envie um email**: Com o transporter configurado, você pode definir o conteúdo do email e enviá-lo.
```javascript
let mailOptions = {
from: 'seu-email@gmail.com',
to: 'destinatario@example.com',
subject: 'Assunto do Email',
text: 'Corpo do email em texto simples',
html: '<b>Corpo do email em HTML</b>'
};
transporter.sendMail(mailOptions, (error, info) => {
if (error) {
return console.log(error);
}
console.log('Email enviado: ' + info.response);
});
```
### Exemplos Práticos
Para facilitar ainda mais o entendimento, vamos ver alguns exemplos práticos de como usar o Nodemailer em diferentes cenários:
#### Enviando um Email de Boas-Vindas
```javascript
const enviarEmailBoasVindas = (emailDestinatario) => {
let mailOptions = {
from: 'seu-email@gmail.com',
to: emailDestinatario,
subject: 'Bem-vindo à Nossa Plataforma!',
html: '<h1>Olá!</h1><p>Obrigado por se registrar em nossa plataforma.</p>'
};
transporter.sendMail(mailOptions, (error, info) => {
if (error) {
return console.log(error);
}
console.log('Email de boas-vindas enviado: ' + info.response);
});
};
enviarEmailBoasVindas('novo-usuario@example.com');
```
#### Enviando um Email com Anexo
```javascript
let mailOptions = {
from: 'seu-email@gmail.com',
to: 'destinatario@example.com',
subject: 'Documento Importante',
text: 'Por favor, veja o documento anexo.',
attachments: [
{
filename: 'documento.pdf',
path: '/caminho/para/o/documento.pdf'
}
]
};
transporter.sendMail(mailOptions, (error, info) => {
if (error) {
return console.log(error);
}
console.log('Email com anexo enviado: ' + info.response);
});
```
### Conclusão
Nodemailer é uma ferramenta poderosa e essencial para desenvolvedores que precisam implementar funcionalidades de envio de email em suas aplicações Node.js. Sua flexibilidade e facilidade de uso a tornam uma escolha excelente, seja para projetos pequenos ou grandes.

I have recently released version [0.37.0](https://github.com/rojopolis/spellcheck-github-actions/releases/tag/0.37.0) of the GitHub Action for doing spelling checking of your documentation etc. for which I am the current maintainer.
- Docker base image bumped to Python 3.12.2
- and before I got around to getting that release out of the way, the Docker base image was bumped to Python 3.12.3
Since the release process requires a lot of steps I have [implemented a basic Perl script](https://github.com/rojopolis/spellcheck-github-actions/commits/master/scripts/build.pl) to help me out. I used it for this release, but have since made some corrections, since I found a few minor issues when doing the release.
The goal is to get this into a GitHub Action, but just getting many of the steps automatically updated, does make it somewhat easier.
At the same time I am looking into issue [#193](https://github.com/rojopolis/spellcheck-github-actions/issues/193). I find the documentation and advice in regard to publishing Docker images for varies architectures a bit messy and it seems a bit _experimental_ so if anybody has any pointers in this regard, I am all ears.
## Change Log
### 0.37.0, 2024-01-01, maintenance release, update not required
- Docker image updated to Python 3.12.3 slim via PR [#199](https://github.com/rojopolis/spellcheck-github-actions/pull/199) from Dependabot. [Release notes for Python 3.12.3](https://docs.python.org/release/3.12.3/whatsnew/changelog.html)
- Docker image updated to Python 3.12.2 slim via PR [#197](https://github.com/rojopolis/spellcheck-github-actions/pull/197) from Dependabot. [Release notes for Python 3.12.2](https://docs.python.org/release/3.12.2/whatsnew/changelog.html) | jonasbn |

1,878,316 | ASO 101: App store optimization for Amazon Developers | This may not be an exact quote from Field of Dreams, but it’s true. There are literally millions... | 0 | 2024-06-05T18:26:39 | https://developer.amazon.com/apps-and-games/blogs/2024/06/app-store-optimization | aso, amazon, tutorial, firetv |
**This may not be an exact quote from *[Field of Dreams](https://www.amazon.com/Field-Dreams-Kevin-Costner/dp/B000I9S668)*, but it’s true.**
There are literally millions of apps out there, so how can you make your app stand out? Especially if (like most of us) you don’t have millions (or even thousands) of dollars to spend on advertising.
Welcome to ASO! ASO stands for App Store Optimization and it means optimizing your app to improve its visibility and ranking in search results.
So let’s get into how you can apply ASO to your app, especially if you develop for Amazon devices.
## Part 1: Getting ready to submit your app
#### Developer name
Before we even get to your app, let’s back up and talk about your company name. It’s not just your app title and keywords that are indexed in search, your developer name is too. So don’t just pick the first thing that comes to mind.
Try to come up with something unique, creative, and appealing. Think Mojang (_Minecraft_), ConcernedApe (_Stardew Valley_), or InnerSloth (_Among Us_). Take a look at list of the [biggest indie games of all time](https://www.ign.com/playlist/rchnemesis/lists/top-100-indie-games). Notice that none of them are from companies called Super Best Free Games, although you’ll find thousands of developers with names just like that. It might seem like using those keywords in your name is a good idea, but it means you and your app will be unmemorable, generic, and you’ll drown in a sea of similar names. Just be sure to avoid [breaking policy](https://developer.amazon.com/docs/policy-center/understanding-content-policy.html?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org) with [IP infringement](https://developer.amazon.com/docs/policy-center/intellectual-property.html?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org) or other violations.
If you already signed up for an Amazon Developer account and you’re regretting the name you chose, don’t worry! You do not need to open a new account, just [follow the guide](https://developer.amazon.com/docs/app-submission/change-company-name.html?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org) to update it.
#### New App Submission
To get started submitting your app, go to the [Amazon Developer Console](https://developer.amazon.com/home.html?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org) and click “Add a New App”.
#### App title
Your app’s title is the first impression customers will have. It should be appealing, descriptive, and unique. If it’s a common word or phrase, it will get buried in thousands of search results.
_Netflix_ tells you exactly what it is in a simple word combination. So does _Minecraft_. So does _YouTube_. Netflix and YouTube were small startups when they began. _Minecraft_ was the work of an independent developer, and if it had been called something boring like _Block Builder_, I don’t think it would have gotten very far.
I recommend checking out [Google’s guide to influencing your title links in search results](https://developers.google.com/search/docs/appearance/title-link).
#### Category
The importance of choosing the right category for your app can’t be overstated. Customers often find new apps by searching through the categories on their devices. Check out the [documentation](https://developer.amazon.com/docs/app-submission/categories.html?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org) for more info.
Be sure to choose a sub-category too. This can help customers find your app through manual search when they’re browsing through categories. Some categories even have further refinements. Take advantage of these and let us know what features your app has!
To get some ideas, take a look through this table for categories. The first column has links to default featured sorting and the other two columns are to view category by best sellers and reviews.

From there, you’ll do [Step 2: Target Your App](https://developer.amazon.com/docs/app-submission/target-app.html). Review the guides to [Supported devices](https://developer.amazon.com/docs/app-submission/target-app.html#supported-devices) and [Availability](https://developer.amazon.com/docs/app-submission/target-app.html#availability).
### Target audience
If you want your app to be available for all ages, or it’s aimed at children, make sure you read and follow the [child-directed app policy](https://developer.amazon.com/docs/policy-center/privacy-children.html?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org), or it may be restricted. If you’ve made an app aimed at kids but haven’t followed policy, it won’t matter how good your ASO is, because it won’t be available for them.
#### Content rating
Review the [Amazon Appstore Content Policy](https://developer.amazon.com/docs/policy-center/understanding-content-policy.html?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org) and take an extra look at the [Listing and Promotion Policy](https://developer.amazon.com/docs/policy-center/listing-promo.html?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org), which is especially relevant for ASO. That guide will help you make sure your [metadata](https://developer.amazon.com/docs/policy-center/listing-promo.html#metadata?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org) is compliant, so it will be visible to as many people as possible.
For the [User Data Privacy](https://developer.amazon.com/docs/app-submission/appstore-privacy-labels.html?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org), select just the labels your app needs, so you build customer trust.
It may be tempting to rush through these sections and select all or nothing, but that can cause delays, violations, and ultimately hurt searchability and word-of-mouth.
From there, we move on to [Step 3: Appstore Details](https://developer.amazon.com/docs/app-submission/appstore-details.html). Choose the right [price](https://developer.amazon.com/docs/app-submission/appstore-details.html#pricing?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org) for your app and then...
#### Display title
The [display title](https://developer.amazon.com/docs/app-submission/appstore-details.html#display-title?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org) is the title that will appear to customers. By default it’s the same as the app title, but if you want to have a different internal title for your company, you can set the app title as your internal title, and the display title as your external title. So the display title is the one that’s important for ASO.
#### Descriptions and feature bullets
Keep your [descriptions](https://developer.amazon.com/docs/app-submission/appstore-details.html#description?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org) snappy and, of course, descriptive. Even if your app pops up in search results, if the description is confusing or unappealing, the customer won’t download it and it won’t matter. Same thing with the bullets. These can be indexed in search results and LLMs outside of Amazon too.
#### Keywords
[Keywords](https://developer.amazon.com/docs/app-submission/appstore-details.html#add-keywords?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org) are optional, but take the option and use them! They are indexed by Amazon’s search algorithm and are super helpful for customers trying to find an app.
Try to imagine the search experience from a customer’s perspective. If you were searching for a great planner app, how would you do that? I’d type “planner app” into the search bar and then pick the one with the best ratings and reviews. I think that’s what most people would do. So if your planner app is called _To Do List_, make sure you put “planner” in the keywords, so it will be indexed for that search term as well.
|App metadata details |Required? |Max length |Description |
|--- |--- |--- |--- |
|Display title |Required |200 chars |The title of your app, shown to customers in the Appstore |
|Long description |Required |4000 chars |A lengthier description of your app, for the Appstore website. |
|Short description |Required |1200 chars |A brief description of your app, shown on mobile devices. |
|Product feature bullets |Required |10 lines |Up to 10 key features of your app, one feature per line. These features will appear on the Appstore website, formatted as a bulleted list. |
|Add keywords (optional) |Optional | |Search terms used to increase the discoverability of your app, Use a comma or white space to separate your terms. |
#### Localization
If you're listing your app in multiple locations where they speak other languages, I recommend adding localized descriptions. Portuguese customers are probably not going to be searching for apps using English keywords, they'll use Portuguese. You can even add different display titles for different locations! Check out the guide to [Distribute Your App Internationally](https://developer.amazon.com/docs/app-submission/distribute-your-app-internationally.html?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org) for more info.
#### Images and videos
While having good [images and videos](https://developer.amazon.com/docs/app-submission/appstore-details.html#images-and-videos?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org) doesn’t directly influence search results, it of course indirectly influences them. The better your pictures are, the more people will download your app, and the higher your app will rank in search results. Who’s going to download an app with low quality images? They’re going to assume the app is low quality as well.
All apps need to submit tablet assets (including square icons) but only Fire TV apps need to submit Fire TV assets (including 16:9 images). If you have a Fire TV app, you may be tempted to dash off some low quality tablet icons, but these are how customers will see your app on the Amazon website, so make sure these are high quality as well.
From here you can move on to [Step 4: Review and Submit](https://developer.amazon.com/docs/app-submission/review-submit.html?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org). Once you’ve submitted your app, it’s been [reviewed](https://developer.amazon.com/docs/app-submission/review-submit.html#overview-of-the-app-approval-process?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org), and gone live, you may be tempted to lean back, celebrate, and call it a job well done. And you should! But once you’re done celebrating, there’s a lot more work to be done, so let’s get to it.
## Part 2: Your app is live, now what?
What else can you do to make your app the hit it deserves to be?
#### The customer search experience
What’s it like for a customer searching for an app?
On Fire tablets, customers might search for your app in the universal search bar at the top of the screen or they might search directly in the Amazon Appstore. Check out this video with examples of both kinds of search.
{% embed https://youtube.com/shorts/P2-thwv-gVo %}
On Fire TV, they might search by typing in the title or they might use [Alexa Voice Search](https://developer.amazon.com/docs/fire-tv/implementing-search.html#voicesearch?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org).
They’re not always going to take the recommended approach. Customers who aren’t technically savvy are just as valuable as ones who are.
Try searching for your app with as many different approaches as you can. Does your app rank higher on one list than the other? Think about why that might be and work on making your app more searchable on all platforms.
Don’t assume that your app will maintain its ranking. Algorithms change and customers’ tastes change. You should always be working on improving your app and the same goes for the images, keywords, etc.
#### Ratings & reviews
Monitor the [ratings & reviews](https://www.amazon.com/gp/help/customer/display.html?nodeId=G8UYX7LALQC8V9KA) your app receives. A lot of people want to argue with any negative reviews they receive. But the reviewer is just giving their honest feedback; it doesn’t matter if it’s not fair or not your fault. Think about what you can do to improve their experience! Everyone gets bad reviews now and then, the important thing is how you learn from them.
#### Ads & promotion
If you have a Fire TV app, you might consider promoting your app with the [Fire TV Self-Service Advertising console](https://developer.amazon.com/apps-and-games/blogs/2024/04/promote-your-fire-tv-app?cmp=US_CON_DEV-amazonappdev&ch=soc&chlast=soc&pub=devto&publast=devto&type=org&typelast=org). It’s easy for a new app to get lost in the mix. Giving it a little promotional push might be all it takes for your app to start being shared organically, via word-of-mouth and high placement in search.
Good luck! There are millions of apps out there and customers are not starved for choice, but if you make something good, people will want it. You just have put in the work to let them know about it.

1,878,359 | Understanding OTP SMS Bombing | Hey Dev Community! Today, let's talk about a concerning issue that's been affecting many individuals... | 0 | 2024-06-05T18:07:08 | https://dev.to/vidyarathna/understanding-otp-sms-bombing-54a4 | smsbombing, security, cybersecurity, cyberthreats |
Hey Dev Community!
Today, let's talk about a concerning issue that's been affecting many individuals and businesses: OTP SMS bombing.
OTP (One-Time Password) SMS bombing occurs when malicious actors flood a person's phone with numerous OTP messages, often with the intent of gaining unauthorized access to accounts, causing inconvenience, or even committing fraud. This type of attack can be particularly troubling as it targets a crucial security mechanism used for authentication and verification purposes.
So, why is OTP SMS bombing a problem? Well, apart from the obvious inconvenience of receiving a barrage of messages, there are serious security risks associated with it. If an attacker successfully intercepts an OTP and gains access to your accounts, they could compromise sensitive information or perform unauthorized transactions.
Now, how should you respond if you find yourself on the receiving end of OTP SMS bombing? Here are a few steps you can take:
1. **Stay Calm:** It's natural to feel overwhelmed or stressed when bombarded with numerous messages, but try to remain calm and composed.
2. **Don't Respond:** Resist the urge to engage with the attacker or reply to any of the messages. Responding could potentially escalate the situation or confirm that your number is active.
3. **Block the Sender:** Most messaging apps and mobile devices allow you to block specific phone numbers. Take advantage of this feature to prevent further messages from the attacker.
4. **Report the Incident:** Inform your phone carrier or service provider about the SMS bombing incident. They may be able to investigate the issue and take necessary actions to mitigate it.
5. **Review Account Security:** As a precautionary measure, review the security settings of your accounts and consider enabling additional security measures such as two-factor authentication (2FA) apps or hardware keys.
6. **Stay Informed:** Keep yourself updated about the latest security threats and best practices for protecting your personal information and digital assets.
By staying vigilant and taking proactive steps to protect yourself, you can minimize the impact of OTP SMS bombing and safeguard your online accounts and privacy.
In conclusion, it's essential to emphasize that SMS bombing, or any form of harassment or malicious activity, is unethical and unacceptable. It not only disrupts the lives of innocent individuals but also poses significant security risks and undermines trust in digital communication systems.
As members of the developer community, we have a responsibility to promote ethical behavior and contribute to a safe online environment for everyone. Let's respect each other's privacy and security, and work together to combat cyber threats effectively.
Remember, staying informed, practicing good cybersecurity hygiene, and advocating for responsible digital behavior are crucial steps in creating a safer and more secure online world for all.
Let's stand united against SMS bombing and other forms of cyber misconduct, and strive to make the internet a better place for everyone.
Stay safe, stay ethical, and happy coding!

Whether you're a data scientist, an analyst, or just someone who wants to make sense of numbers, mastering data visualization can make a huge difference. In this blog post, we'll dive into some of the best tools and techniques for creating captivating data visualizations.
## Why Data Visualization Matters
Before we dive into the tools, it's important to understand why data visualization is so crucial. Let me break it down for you:
1. Simplifies Complex Data: It takes those big, complicated datasets and transforms them into visuals that are easy to understand.
2. Reveals Insights: Data visualization helps us uncover patterns, trends, and connections that we might miss when looking at raw data alone.
3. Improves Decision Making: Clear visuals make it easier for us to make informed decisions quickly. It's like having a visual guide to help us navigate through the data jungle.
4. Engages the Audience: Let's face it, engaging visuals grab our attention way better than boring numbers. They make the data come alive and keep us hooked.
So, data visualization is like a superhero that simplifies the complex, reveals hidden treasures, and helps us make smarter decisions. It's a win-win for everyone involved!
## Popular Data Visualization Tools
**Tableau**
Tableau is one of the most popular data visualization tools out there. It's known for its user-friendly interface and its ability to handle large datasets without a hitch. Plus, it has a huge community of users who can provide support whenever you need it.

For those working with the R programming language, ggplot2 is a fantastic data visualization package. It's based on the Grammar of Graphics, which means you have a lot of flexibility to create a wide range of visualizations.
_Pros_: It's highly customizable, and it plays well with other R packages.
_Cons_: Just keep in mind that it requires knowledge of R, and when dealing with large datasets, it might be a bit slow.
There you have it! These are some of the best data visualization tools available, each with its own strengths and weaknesses.
## Techniques for Effective Data Visualization
**1. Know Your Audience**
Understanding who will be viewing your visualization helps in tailoring the complexity and type of visuals used. Business executives might prefer high-level summaries, while analysts might need detailed charts.
**2. Choose the Right Chart Type**
Different types of data require different chart types. Bar charts are great for comparisons, line charts for trends, and scatter plots for relationships.
**3. Keep it Simple**
Avoid clutter. Focus on the key message you want to convey and remove any unnecessary elements that might distract the viewer.
**4. Use Colors Wisely**
Colors can make or break your visualization. Use them to highlight important data points and maintain consistency. Be mindful of colorblind-friendly palettes.
**5. Tell a Story**
Your visualization should guide the viewer through the data, highlighting key insights and supporting them with evidence. A good narrative makes the data more relatable and understandable.
Data visualization is the radar by which a right oriented approach is assured in presentation of raw data if and when processed well. Whether you are using Tableau, Power BI, D3 or other similar software tools. Whether choosing between JavaScript, Plotly, or ggplot2, the goal is to ensure that your visualization is easy to understand and is as simple as possible while maintaining the flow of the story being narrated. Happy visualizing!

1,878,355 | Como Configurar uma Pipeline para Bitbucket Pipelines em um Projeto Node.js | Introdução Bitbucket Pipelines é uma ferramenta poderosa de integração contínua e entrega... | 27,690 | 2024-06-05T17:58:38 | https://dev.to/vitorrios1001/como-configurar-uma-pipeline-para-bitbucket-pipelines-em-um-projeto-nodejs-32ph | pipeline, cicd, bitbucket, node | ### Introdução
Bitbucket Pipelines é uma ferramenta poderosa de integração contínua e entrega contínua (CI/CD) que permite automatizar a construção, teste e implantação de seu código diretamente do Bitbucket. Neste artigo, vamos mostrar como configurar uma pipeline para um projeto Node.js utilizando o Bitbucket Pipelines.
### Pré-requisitos
- Conta no Bitbucket.
- Repositório do Bitbucket com um projeto Node.js.
- Conhecimento básico em YAML.
### Passo 1: Criar o Arquivo de Configuração
O primeiro passo é criar um arquivo de configuração para o Bitbucket Pipelines. Esse arquivo deve ser chamado `bitbucket-pipelines.yml` e deve ser colocado no diretório raiz do seu projeto.
### Passo 2: Configurar a Pipeline Básica
Aqui está um exemplo básico de configuração de pipeline para um projeto Node.js:
```yaml
image: node:14
pipelines:
default:
- step:
name: Install dependencies
caches:
- node
script:
- npm install
- step:
name: Run tests
script:
- npm test
- step:
name: Build and deploy
script:
- npm run build
- ./deploy.sh # Supondo que você tenha um script de deploy
```
#### Explicação dos Campos
- **image**: Define a imagem Docker que será usada para rodar o pipeline. Neste caso, estamos usando a imagem oficial do Node.js.
- **pipelines**: Define os pipelines que serão executados. No exemplo, estamos usando o pipeline padrão (`default`).
- **step**: Cada passo define um conjunto de comandos a serem executados.
### Passo 3: Configuração Detalhada
Para um cenário mais complexo, por exemplo, se você quiser que o deploy seja executado apenas em branches específicas como `main` ou `develop`, você pode configurar da seguinte forma:
```yaml
image: node:14
pipelines:
default:
- step:
name: Install dependencies
caches:
- node
script:
- npm install
- step:
name: Run tests
script:
- npm test
branches:
main:
- step:
name: Build and deploy to production
script:
- npm run build
- ./deploy.sh
develop:
- step:
name: Build and deploy to staging
script:
- npm run build
- ./deploy-staging.sh
```
### Passo 4: Variáveis de Ambiente
Se o seu processo de deploy precisar de variáveis de ambiente (por exemplo, chaves de API, credenciais, etc.), você pode configurá-las diretamente no Bitbucket:
1. Vá para o seu repositório no Bitbucket.
2. Clique em **Repository settings**.
3. Vá para a seção **Pipelines** > **Environment variables**.
4. Adicione as variáveis necessárias.
### Passo 5: Script de Deploy
Aqui está um exemplo simples de um script de deploy (`deploy.sh`) que você pode usar para copiar o build para o servidor e reiniciar a aplicação:
```bash
#!/bin/bash
# Fazer o deploy do build para o servidor
scp -r ./build user@your-server:/path/to/deploy
# Rodar comandos no servidor remoto
ssh user@your-server << 'EOF'
cd /path/to/deploy
npm install --production
pm2 restart your-app
EOF
```
### Explicação do Script
- **scp**: Este comando copia recursivamente a pasta `./build` para o servidor remoto.
- **ssh**: Este comando executa comandos no servidor remoto. No exemplo, ele navega até o diretório de deploy, instala as dependências de produção e reinicia a aplicação usando `pm2`.
### Conclusão
Configurar uma pipeline no Bitbucket Pipelines é uma maneira eficiente de automatizar o processo de construção, teste e implantação de seu projeto Node.js. O exemplo fornecido aqui é um ponto de partida que você pode personalizar conforme suas necessidades específicas.
A automação de tarefas repetitivas não só economiza tempo, mas também reduz o risco de erros humanos, garantindo que o código seja testado e implantado de maneira consistente.
Se você tiver dúvidas ou precisar de mais detalhes sobre algum dos passos, sinta-se à vontade para perguntar!

---
#### For Large Data Set Ingestion — Advanced Cost Control Measures Are Required that Optimize Data Sets at Before or At Ingest
What approaches would work if you are constantly ingesting data, real-time or not, if you have petabytes of data or billions of rows it can add up and account for a lot of the cost in your Snowflake and Cloud implementations.
A recent client was ingesting a high volume of data that was repetitively processed daily, but changes in data updates existed even for records up to five years before.
Ultimately, you will need to try to reduce the initial data set or change how you are ingesting your data.
#### Tip 1: Snowpipe Streaming
For streaming, move to Snowpipe Streaming. It gives you considerable savings. One person I spoke with recently talked about the cost going from 500 dollars/day to 27 dollars/day when they moved from Snowpipe to Snowpipe Streaming. Snowflake Sales Engineers estimate Snowpipe is about 1/3 of the cost, but the example is much better.
If you are looking to learn how to implement Snowpipe Streaming, try this[ lab](https://quickstarts.snowflake.com/guide/getting_started_with_snowpipe_streaming_aws_msk/index.html?index=..%2F..index#3).
#### Tip 2: Optimize for Deltas
When dealing with large datasets resulting from multiple API calls, it’s better to optimize deltas, which is the difference between two subsequent load dates. Typically, only around 5% of the data changes daily, so instead of using the entire dataset for each load, we can analyze the changes from the previous load and use only the 5% of data that has changed. This approach can significantly improve the next steps in the data analysis process.
Even if it is not an API call, if the ingestion requires a comparison of tables, there you would still benefit from this tip. This is a large data set that may have to unpack and clean, or dedupe and merged.
#### Tip 3: Don’t keep the history in the intermediate tables
Often, historical data are kept in the intermediate-working tables. Our take is: don’t keep it for more than one reason. First, it will save storage. Secondly, it reduces the risk of an inefficient execution plan. Third, it provides an opportunity to use a better clustering key, as you no longer have to partition your data by load date.
#### Tip 4: File size for ingestion: 100–250 MB
It seems small, but following Snowflake’s recommendation for file size is a great help. It does seem to improve ingestion, as it makes any COPY INTO statements as efficient as possible. If you can control file sizes, it would be great. Smaller files reduce the overhead charge relative to the amount of total data loaded to the point where the overhead cost is immaterial. An efficient data pipeline is a cheaper pipeline.
#### Tip 5: Parquet format
The final tip not to be discounted is to use the Parquet format instead of the typical CSV.
Parquet provides an efficient compression with smaller file sizes and improved columnar storage. With better compression ratios and faster read times for analytical queries that access specific columns. Smaller file sizes mean faster transfer rates and reduced storage costs. With the optimized structure and smaller size, you can parallel process things.
Plus, you gain metadata, making your queries faster as well.
### Conclusion
As we have explored, managing costs while ingesting extensive data sets into Snowflake requires a strategic data handling and processing approach. Organizations can significantly reduce their cloud and Snowflake costs by optimizing data ingestion through Snowpipe Streaming, focusing on deltas, and minimizing unnecessary historical data storage.
Incorporating the strategies mentioned in this blog can help you reduce expenses and improve the overall efficiency of your data management system. These tips should be viewed not only as cost-saving measures but also as essential components of a strong data strategy promoting scalable, efficient, and cost-effective Snowflake operations. To ensure your data processes remain lean and robust, encourage a culture of continuous learning and keep yourself updated with the latest methods and trends.

Those are all warning signs that your brake pads or discs need some attention. But how do you know when it’s time for replacements and what types are best? We get it, brakes aren’t the most exciting topic, but they are one of the most important parts of your vehicle. In this article, we’ll give you the complete lowdown on **[brake pads and discs](https://autospartoutlet.com/collections/brakes-and-rotors)** in 2024 so you can make informed decisions when maintenance time comes. We’ll cover types of materials, new tech, when to replace, and everything in between regarding these essential components. You’ll be a brake expert by the time you reach the end!
## Understanding Brake Pads and Disks
Brake pads and disks are two of the most important components in your vehicle's braking system. The brake pads clamp down on the brake disks, which spin with your wheels, to slow and stop your vehicle.
- Brake Pads
The brake pads are the friction material that presses against the brake disks. There are several types of brake pads used today: organic, metallic, and ceramic. Organic pads are made of fibers and resins, metallic pads contain steel wool and copper fibers, while ceramic pads use ceramic fibers and fillers. Ceramic pads tend to last the longest but produce more brake dust. The type of brake pads you need depends on how you drive and the make and model of your vehicle.
- Brake Disks
The brake disks, also known as rotors, are the spinning plates that the brake pads clamp onto. Brake disks come in a variety of sizes depending on your vehicle. They can be solid or vented, with vented disks more common on high-performance vehicles as they help dissipate heat. As the brake pads wear down over time and use, the brake disks also gradually wear away and may need to be resurfaced or replaced.
Neglecting your brake pads and disks is dangerous, so most manufacturers recommend inspecting them regularly and replacing them every 20,000 to 60,000 miles depending on driving conditions and style. While brake work can be expensive, properly maintaining this critical system helps ensure safe and reliable braking and extends the life of your brake components. Keeping your brake pads and disks in good working order is well worth it for the enhanced safety and performance of your vehicle.
## When to Replace Your Brake Pads and Disks
- Brake pads
Brake pads are the friction material that presses against your brake discs to slow and stop your vehicle. Over time, brake pads wear down through normal use and need to be replaced. If your brake pads get too worn, they won't grip the brake discs effectively and you'll start to notice reduced braking power, squealing sounds when braking, and the brake pedal pulling or vibrating. Most brake pads need to be replaced every 20,000 to 60,000 miles depending on your driving conditions and habits.
- Brake discs
Brake discs, also known as brake rotors, are the metal plates that brake pads clamp onto. Brake discs can become damaged, warped or worn over time which reduces their ability to stop your vehicle. Signs that your brake discs may need replacement include thick brake dust on the front of the wheel, visible grooves or scoring in the brake disc surface, a squealing or grinding noise when braking at high speeds, or shaking felt through the brake pedal. Brake discs typically last between 20,000 to 60,000 miles but driving style and road conditions can shorten or extend their lifespan.
- When to replace
The general rule of thumb is that if your brake pads have worn down to about 1/4 inch of pad thickness remaining or your brake discs show signs of damage or are worn below minimum thickness specifications, it's time for replacement. It's best to have your brake pads and discs inspected regularly by a certified mechanic to determine if replacement is needed based on the condition and wear of your specific brake components. Replacing brake pads and discs before they become too worn will ensure safe and effective braking performance and prevent costly damage to other brake parts.
## Choosing the Best Brake Pads and Disks in 2024
- Look for Efficient Brake Pads
In 2024, brake pad technology will continue advancing to improve stopping power and durability. Look for pads made of ceramic, semi-metallic, or carbon materials, which provide strong braking without excessive noise or dust. Ceramic and carbon pads are also easier on your brake discs. For the average driver, any of these materials will work great. High-performance vehicles may benefit from more aggressive pad compounds.
- Consider Slotted or Drilled Discs
Slotted or drilled brake discs, also known as “rotors,” help your brake pads grip better, which can improve stopping power. Drilled discs are lightweight and help vent heat, while slotted discs remove water, dust and gases from between the pads and discs. Either type should work with most standard brake pads. However, drilled or slotted discs may wear out pads slightly faster and can be more expensive. For typical driving, standard solid discs will work fine.
## Choose a Trusted Brand
When it comes to brakes, quality and safety are most important. Stick with a reputable brand that specializes in brakes, like Brembo, Bosch, or Wagner. Lesser-known brands may be cheaper, but brakes are not something to cut corners on. Look for brands that offer at least a 12-month or 20,000 mile warranty on pads and discs. This ensures you're getting components built to last.
## Buy a Complete Brake Job
For the best results, replace your brake pads and discs at the same time. Worn out pads can damage new discs, and worn discs won't allow new pads to grip properly. A complete brake job will ensure even braking and the maximum service life from your new components. While a complete brake replacement may cost more up front, you'll save money in the long run.
In 2024, braking technology will continue advancing to improve your vehicle's stopping power and safety. By choosing high-quality, durable brake pads and discs, you can count on smooth, quiet braking for years to come. Focus on efficient, advanced materials, trusted brands, and replacing pads and discs together for the best results. With regular inspections, your brakes should keep you safe for many miles down the road.
## Conclusion
So there you have it, the full scoop on brake pads and discs in 2024. You now know all about the different materials, pros and cons, and newest tech when it comes to braking components. Whether you're looking to upgrade your own ride or just learn more about how your car stops, hopefully this info gave you a helpful overview. The bottom line is that as technology keeps advancing, we'll continue to see improvements in brake pad formulas and disc designs. And that means smoother, quieter, and safer stops for drivers. But no matter what's on your car, remember to keep up with maintenance and replace wear items as needed. Quality brakes are too important to ignore. Drive safe!

1,878,351 | 7 Ways to Improve Asset Visibility | Every asset in your cyber-physical systems (CPS) environment can also be a vulnerability. Without... | 0 | 2024-06-05T17:39:41 | https://claroty.com/blog/7-ways-to-improve-asset-visibility | cybersecurity, iot | Every asset in your cyber-physical systems (CPS) environment can also be a vulnerability. Without having complete asset visibility, companies are operating in the dark, leaving potential security gaps unattended and significantly increasing exposure to cyber-attacks and data breaches.
43% of companies plan to invest in [exposure management](https://claroty.com/resources/reports/the-global-state-of-industrial-cybersecurity-2023) this year, so organizations are already working toward becoming more proactive in detecting, monitoring, and mitigating risks within their systems.
However, this preventative approach can't be successfully implemented without a clear first step: ensuring you have complete visibility into each asset, its potential security gaps, and how it is being used.
What is asset visibility?
-------------------------
Asset visibility encompasses several methods to detect all devices on your network and develop a comprehensive inventory of all cyber-physical assets. It helps businesses track the entire lifecycle of their devices, including their location, status, how they are utilized, and how they interact with each other.
Not all visibility methods offer the same level of information to [secure IoT assets and OT](https://claroty.com/blog/iiot-security-essentials) specifically. The optimal level of visibility reveals key identifying attributes such as the asset's model, firmware version, and configuration information. You need this in-depth information to detect all hidden vulnerabilities across your network.
To achieve complete asset visibility, you should be able to detect and monitor a wide range of devices, including IT, OT IoT, IoMT, and the full spectrum of XIoT devices. Visibility also plays a significant role in uncovering unknown and end-of-life assets, which are typically outdated and may have security gaps. These gaps can have many concerning consequences, impacting everything from data privacy to physical safety.
In addition to asset detection, visibility improves overall cyber security hygiene. It strengthens your security posture, enabling you to respond to threats promptly before they escalate into full-scale attacks. Without asset visibility, it's impossible to fully know which devices need protection, making it easy for attackers to slip through the gaps or exploit vulnerabilities on devices you weren't aware even existed.
### Asset Visibility vs Asset Management
Asset visibility refers to discovering every asset on your network to offer protection from cyber threats. Gathering information about these devices allows you to better understand how to protect them.
On the other hand, asset management is the logical next step after visibility, which includes acting on the information gleaned from discovery to secure the device, from proper [exposure management](https://claroty.com/blog/a-comprehensive-guide-to-exposure-management-for-cyber-physical-systems) to essential steps like risk scoring.
The Benefits of Asset Visibility
---------------------------------
- Better threat detection - to stay on top of potential threats or vulnerabilities in the devices on your network, you must be able to monitor your assets continuously. Visibility is the first step in enabling total asset management.
- Operational efficiency - asset visibility leads to a higher level of protection, meaning fewer viruses or malware that could lead to downtime. When all devices are detected on the network, you can remain more confident in your security posture and overall efficiency.
- Compliance - monitoring and managing all devices on your network is critical to meeting all industry regulations to avoid penalties or fines. For example, compliance with HIPAA requires all healthcare organizations to securely manage and dispose of assets that contain [patient health information (PHI)](https://www.memcyco.com/home/pii-vs-phi/).
- Exposure management - By mapping communication paths and protocol usage, you can monitor threats and generate unique risk scores based on the exploitability of your devices, ensuring you can identify, assess, and address exposures.
Asset visibility is especially important when you consider that organizations in the healthcare industry are more reactive than proactive when identifying asset and supply chain risk, as determined in a [KLAS survey](https://klasresearch.com/report/healthcare-cybersecurity-benchmarking-study-how-aligned-is-the-industry-to-nist-and-hicp-best-practices/3102) that identified asset visibility as a weak spot across the healthcare industry.
Why do you need asset visibility now?
-------------------------------------
From proactively managing cyber risks, optimizing operational efficiency, adhering to regulations, and protecting your brand reputation, it has never been more critical for enterprises to have asset visibility. Every industry needs to fully implement asset visibility to secure its CPS.
The challenges we face from cyber security threats are only increasing in sophistication as the complexity of CPS environments grows. With more remote work comes greater network connectivity and a more significant number of entry points for adversaries to gain access to the network.
Taking measures to prevent cyber-attacks means preventing operational failures, like [supply chain threats](https://spectralops.io/blog/10-steps-to-take-now-to-reduce-supply-chain-risks/) and other disruptions to critical workflows. This is also key to preserving reputation management and fulfilling your organization's mission.

6 Ways to Improve Asset Visibility
----------------------------------
### 1\. Establish network visibility
To have visibility of every asset on your network, it's vital to ensure you have complete network visibility first. Deep packet inspection and network monitoring tools help you understand how data flows between your devices and gather relevant insights into what is happening within your systems.
However, there isn't a one-solution-fits-all solution available, and some tools may not be advanced enough to monitor complex industrial control systems (ICS) and operational technology (OT) systems. Using specialized network monitoring tools and methods will enable you to capture the proper protocols, avoid data transmission [latency](https://controlplane.com/community-blog/post/4-tips-to-improve-p99-latency), and continue operating efficiently.
### 2\. Deploy network traffic analysis tools
Your network traffic includes signals from every device on your network. Some devices will contribute more traffic than others, but that doesn't mean they are more or less critical. By analyzing network traffic, organizations can detect abnormal behavior like unauthorized access attempts and unusual data transfers and spot [security misconfiguration vulnerabilities](https://www.suridata.ai/blog/common-security-misconfiguration-vulnerabilities/) that could be exploited.
Analysis tools must be able to understand every protocol coming through your network. Deploying tools that can accurately detect the hundreds of [proprietary protocols](https://claroty.com/blog/gartner-market-guide-for-cps-protection-platforms), spanning all of your OT, BMS, IoT, and other XIoT assets, is imperative to maintaining complete visibility and taking the next step to manage your assets.
Source: https://www.spiceworks.com/tech/networking/articles/network-traffic-analysis/
You should also monitor user activity logs to understand how your assets are being used and identify potential threats. You can then add the relevant access control measures to your broader IT security policy, ensuring that users have only the privileges they need to perform their tasks and avoiding privilege escalation.
### 3\. Implement endpoint detection and response (EDR)
Network security focuses on protecting the network infrastructure via specialized monitoring tools, firewalls, and encryption protocols. These tools primarily analyze the data flow within the network to [detect suspicious activity.](https://www.openappsec.io/post/threat-detection-and-response-tdr) On the other hand, endpoint security solutions aim to protect specific devices or endpoints, such as IoT devices and servers.
You should combine both approaches and employ [endpoint detection and response (EDR)](https://claroty.com/blog/crowdstrike-claroty-best-practices-for-securing-industrial-environments-part-1-secure-the-known) tools to protect the IoT. An EDR, like the CrowdStrike Falcon platform, responds to cyber threats by continuously monitoring end-user devices. You can improve your security posture by pairing it with other [continuous threat detection methods (CTD)](https://claroty.com/resources/datasheets/continuous-threat-detection).
### 4\. Regularly conduct asset discovery and classification
Networks and devices aren't static, so [OT asset discovery](https://claroty.com/blog/ot-asset-discovery) should be continuous. You should systematically scan your network to identify all connected devices and ensure they are protected. Ensure you leverage various asset discovery methods such as segmentation, active and passive discovery, Claroty's proprietary AppDB, and OT-specific techniques.
Regarding classification, knowing exactly what type of devices are active on your network, their model, and other identifying details can help determine the proper protocols to use with them. It also helps improve resource efficiency, as you'll know what devices to prioritize.
### 5\. Consider segmentation
Network segmentation involves dividing the network into separate, isolated segments based on factors such as asset criticality, function, or security requirements. Segmenting different assets can make it easier to track which devices can communicate with one another, track the number of devices on your network, and control overall traffic. To better manage your network, Claroty xDome supports segmentation to define and enforce policies.
Source: https://www.getapp.com/resources/internet-of-things-security/
### 6\. Utilize passive asset discovery methods
Passive scanning is a way to take data from your industrial network and process it in a passive, one-way transfer that offers visibility without any chance of disruption. Downtime or disruption caused by improperly deployed active methods poses a risk to your network, whereas passive methods ensure complete visibility without risk of harm.
### 7\. Consider visibility orchestration tools
The unique nature and often complex communications of CPS render them challenging to discover and profile through passive-only means. Visibility orchestration serves as an additional tool to ensure organizations are deploying the right visibility techniques for their unique environment. With this tailor-made nature of discovery paired with continuous, automated enhancement to visibility, organizations can more quickly operationalize their asset inventory and an overall faster time-to-value.
Gain Optimal Asset Visibility
-----------------------------
Improving asset visibility is critical to proactively detecting threats across IT and OT assets. The steps suggested in this article are the first of many to secure your assets fully. They should be done in tandem with a comprehensive plan to protect devices beyond initial detection and discovery.
A trusted CPS security partner like Claroty's xDome platform helps you gain asset visibility and immediately take the necessary steps to secure those assets. With a full-service platform, you can identify the assets needing protection and offer that protection all in one.

One innovative approach that has gained significant traction is Retrieval Augmented Generation (RAG). RAG combines the strengths of retrieval-based systems and generation-based models to produce more accurate, contextually rich, and informative outputs. This blog will introduce you to RAG and demonstrate how Algoboost, an app specializing in embedding vector inference and vector embedding storage via API, plays a crucial role in this paradigm.
## **Understanding Retrieval Augmented Generation**
The RAG process typically involves two main components:
- **Retriever:** This component searches a database of embeddings to find the most relevant pieces of information related to the input query. These embeddings are precomputed vectors that represent the semantic content of various documents or data points.
- **Generator:** After retrieving relevant information, the generator uses this context to produce a well-informed response. The additional context helps the generator to produce outputs that are not only contextually appropriate but also factually accurate.
**The Role of Algoboost in RAG**
Algoboost is a powerful tool designed to facilitate embedding vector inference and vector embedding storage via API. It seamlessly integrates with the RAG framework, providing essential functionalities that enhance the retrieval and generation process.
**Embedding Vector Inference**
Embedding vector inference is the process of converting text data into fixed-size numerical vectors that capture the semantic meaning of the data. Algoboost excels in this domain by providing robust API endpoints that allow users to infer embeddings from their text data efficiently. These embeddings serve as the foundation for the retrieval process in RAG.
**Vector Embedding Storage**
Once embeddings are generated, they need to be stored in a manner that allows for efficient retrieval. Algoboost offers a sophisticated storage solution for vector embeddings, ensuring that the retrieval process is both fast and scalable. By using Algoboost’s API, developers can store vast amounts of embeddings and retrieve them quickly when needed, facilitating the smooth operation of RAG systems.
## **Implementing RAG with Algoboost: A Step-by-Step Guide**
Before you can start, checkout the [how to get started with algoboost](https://dev.to/tshidisoisazi/introducing-algoboost-revolutionizing-embedding-model-inference-and-vector-storage-4696) blog.
Here’s a simplified overview of how you can implement a Retrieval Augmented Generation system using Algoboost:
- **Generate Embeddings:** Use Algoboost’s API to convert your text data into embedding vectors. This involves sending your text data to Algoboost’s embedding inference endpoint and receiving the corresponding vectors.

- Adicionam reificação às coleções, lançando ClassCastException em inserções incorretas.
**Tokens de Tipo Limitados**
- Exemplo: método getAnnotation na interface AnnotatedElement.
- Utiliza Class<? extends Annotation> como token de tipo limitado.
- Class.asSubclass realiza cast seguro dinamicamente.
**Resumo Final**
- Contêineres genéricos normalmente têm número fixo de parâmetros de tipo.
- Contêineres heterogêneos typesafe usam parâmetros de tipo nas chaves.
- Objetos Class podem ser usados como tokens de tipo.
- Tokens de tipo personalizados também podem ser usados, como DatabaseRow e Column<T>.

Debugging is an inevitable part of a developer's life, because bugs are EVERYWHERE!
Effective debugging is more than just finding errors, it involves understanding how to prevent them in the first place and fix them when you can't avoid them.
In this article let's talk about some practical debugging tips.
---
## 1. Understand the Common Errors
To start, let's get familiar with the most common JavaScript errors. Here are a few to keep an eye on:
- **Syntax Errors**: Often due to typos or incorrect use of language rules.
- **Runtime Errors**: These occur as your program executes, like trying to call a function that doesn’t exist.
- **Logical Errors**: Perhaps the trickiest, these involve no exceptions but lead to incorrect results.
---
## 2. Master the Console
The browser’s console is a powerful tool for debugging, so use it!
- **Console Logging**: Instead of using `alert()`, use `console.log()`, `console.warn()`, and `console.error()` to get insights into how your code is running without disrupting the flow with modal alerts.
- **Assert Statements**: Use `console.assert()` to test if a statement returns true and only print something to the console if the assertion fails.
---
## 3. Leveraging Breakpoints
Breakpoints are your best friend in the debugging process:
- **Set Breakpoints in DevTools**: Use Chrome DevTools or Firefox Developer Tools to set breakpoints where execution will pause.
- **Conditional Breakpoints**: Set breakpoints that only trigger when a specific condition is met. This is useful for debugging loops or multi-conditional statements.

---
## 4. Watch Expressions and Scope
While paused at a breakpoint:
- **Watch Expressions**: Add expressions to watch how values change over time. It helps you monitor the behavior of your code during the execution of specific blocks.
- **Scope Panel**: Check the Scope panel in your dev tools to understand the current context and see what variables are available.
---
## 5. Using Network Tab to Debug API Calls
API calls can often be a source of bugs, so let's try to avoid them:
- **Check the Network Tab**: Ensure that the request is being made correctly and that the response is what you expect.
- **Inspect Headers and Payloads**: Verify that the headers and payloads of your API requests are correctly formatted.
---
## 6. Handling Asynchronous Code
Debugging asynchronous code requires a slightly different approach:
- **Promise Chains**: Ensure promises are returning what you expect and catch any errors properly.
- **Async/Await**: Use `try/catch` blocks effectively to handle errors in async functions.
---
## 7. Tools and Plugins to Enhance Debugging
Explore tools and plugins that can further help with debugging:
- **Linting Tools**: Use ESLint to catch many common bugs before they happen.
- **Debugging Extensions**: Extensions like Augury (for Angular) or React Developer Tools can provide deeper insights into specific frameworks.
---
## Bugs? 🐞
Effective debugging in JavaScript is as much about preventing errors as it is about fixing them. By learning these practical tips you can significantly reduce debugging time and increase your efficiency as a developer.
Share any tools or techniques that have changed the way you debug your code.

### Introduction:
The purpose of this tutorial is to provide an easy and concise way to validate payload with an Express JS application.
We will be using the [**simple-body-validator**](https://www.simple-body-validator.com/validation-quickstart) library to achieve our goal of validating payloads
Let's say that we would like to validate the following payload.
```javascript
{
"name":"John",
"email":"John@gmail.com",
"age":28
}
```
### Installation:
To get started, install the simple-body-validator library:
```bash
npm i simple-body-validator
```
### Validation Rules:
The `simple-body-validator` library offers a variety of validation rules. You can find the full list of rules in the documentation [here](https://www.simple-body-validator.com/available-validation-rules).
```javascript
const rules = {
name: 'required|string|min:3',
email: 'required|email',
age: 'min:18'
};
```
### Code Example:
```javascript
const express = require('express');
const bodyParser = require('body-parser');
const {make} = require('simple-body-validator');
const app = express();
const port = 3000;
// parse application/json
app.use(bodyParser.json());
const rules = {
name: 'required|string|min:3',
email: 'required|email',
age: 'min:18',
};
app.post('/user', (req, res) => {
const validator = make(req.body, rules);
if (!validator.validate()) {
res.status(422).json(validator.errors().all(false));
return;
}
res.send('SUCCESS');
});
app.listen(port, () => {
console.log(`Example app listening on port ${port}`)
});
```
With this setup, your validation is complete! We recommend that you go through the [documentation](https://www.simple-body-validator.com/validation-quickstart) for more complex use cases.

Manual testing is a technique to test the software that is carried out using the functions and features of an application . In manual software testing, a tester tests the software by following a set of predefined test cases. In this testing ,testers make test cases for the codes, test the software ,and give the final report about that software.
Characteristics of MANUAL TESTING:
1. Human performance
2. Investigative Testing
3. Flexibility
4. Initial testing
5. Examining complex situations
6. Testing User interfaces
Need for Manual Testing:
1. Bug-free and stability(stable ,requirement& delivers a stable product to the customers)
2. Familiarity(write correct test cases for the software)
3. Fixing the defects
Manual testing process:
Unit testing:
Unit Testing is also called Module Testing or Component Testing. It is done to check whether the individual unit or module of the source code is working properly.
Integration testing:
Integration Testing is the process of testing the interface between the two software units.
Regression testing:
Repeated testing of an already tested program, after modification, to discover any defects introduced or uncovered as a result of the changes in the software being tested or in another related or unrelated software components.
user interface testing:
security testing:
performance &acceptance testing:
Example: car is a software
Unit testing-->Engine
Types of Manual testing:
1.Black Box Testing:
Black Box Testing is a software testing method in which testers evaluate the functionality of the software under test without looking at the internal code structure. This can be applied to every level of software testing such as Unit, Integration, System and Acceptance Testing.
2.White Box Testing:
White Box Testing is also called as Glass Box, Clear Box, and Structural Testing. It is based on applications internal code structure. In white-box testing, an internal perspective of the system, as well as programming skills, are used to design test cases.
3.Grey Box Testing:
Grey box is the combination of both White Box and Black Box Testing. The tester who works on this type of testing needs to have access to design documents. This helps to create better test cases in this process.
Benefits of manual testing:
1.Fast and accurate visual feedback(detects almost every bug in the software application)
2.Less expensive(specific type of tool)
3.No coding is required(black box testing method using)
4.Efficient for unplanned changes
Drawbacks of manual testing:
1.Less reliable(not provide testing on all aspects testing)
2.Can not be reused(separate test cases for new software)
3.Time -consuming
4.Large human resources required

## 👀 Using egui for Bevy ECS Introspection
In this post, we look at using egui for Bevy Introspection with Macroquad rendering. This continues the series of recent posts, which started with adding egui DevTools to Macroquad, then added Rapier physics, units of measurement and an Entity Component system (**ECS**).
Here, we bring everything together, adding DevTools-like introspection to the Bevy ECS demo from the previous post. As before, the complete project code is on GitHub (link further down).
## 🧱 What are we Building Here?
The demo simulation, built in Rust, shows a series of coloured, floating bubbles release and float to top of the window. The bubbles subsequently get trapped at the top of the screen; filling the window, from the top down.
I employed the following tools to build the demo:
- **Macroquad** — a fast, quick-to-get going on Rust tool built with game prototyping in mind;
- **Rapier** — mature, pure Rust physics engine for game dev;
- **uom** — a crate with applications in Aerospace for maintaining consistency in physical quantity units and helping to avoid unit errors;
- **Bevy ECS** — ECS implementation from the Bevy game engine, added to this project as the stand-alone `bevy_ecs` crate; and
- **egui** — an immediate Graphics User Interface (**GUI**) library for Rust (inspired, in fact, by the <a href="https://rodneylab.com/using-raylib-with-dear-imgui/">C++ Dear ImGui library</a>).
I focus on the egui integration in this post, so feel free to jump back through the series to learn more about how I put the other elements together.
## ⚙️ Crate Setup
You might need to use slightly older (than the latest) versions of some crates to get everything working together. Here is my `Cargo.toml`, which you can use as a starting point for finding compatible versions of `egui`, `egui-macroquad` and `macroquad`:
```toml
[package]
name = "macroquad-bevy-ecs-introspection"
version = "0.1.0"
edition = "2021"
license = "BSD-3-Clause"
repository = "https://github.com/rapier-example"
# bevy_ecs 0.13 requires MSRV 1.76
rust-version = "1.76"
description = "Macroquad Rapier ECS 🦀 Rust game dev — using bevy's 🧩 Entity Component System in a Macroquad game with Rapier physics."
[dependencies]
bevy_ecs = "0.13.2"
crossbeam = "0.8.4"
egui = "0.21.0"
egui-macroquad = "0.15"
macroquad = { version = "0.3.26", default-features = false }
rand = "0.8.5"
rand_distr = "0.4.3"
rapier2d = { version = "0.19.0", features = ["simd-stable"] }
uom = "0.36.0"
```
## 🔄 Update egui Introspection System
I <a href="https://rodneylab.com/macroquad-rapier-ecs/">introduced Bevy ECS to the project in a previous Macroquad Rapier ECS post</a>. Continuing, we need to add a couple of ECS systems for updating and rendering the egui DevTools. First up is the `update_dev_tools_system` in `src/systems.rs`:
```rust
pub fn update_dev_tools_system(query: Query<(Entity, &Position, &Velocity, &CircleMesh)>) {
egui_macroquad::ui(|egui_ctx| {
egui_ctx.set_pixels_per_point(4.0);
egui::Window::new("Developer Tools").show(egui_ctx, |ui| {
ScrollArea::vertical().show(ui, |ui| {
CollapsingHeader::new("Bubbles")
.default_open(false)
.show(ui, |ui| {
for (entity, position, bubble_velocity, circle_mesh) in &query {
draw_ball_ui_data(ui, entity, position, bubble_velocity, circle_mesh);
}
});
});
});
});
}
```
### Bevy ECS Queries
Typically, for Bevy ECS, this function takes a query over ECS components as its argument (line `107`). Here, the query generates a collection of all ECS entities that have `Position`, `Velocity` and `CircleMesh` components (essentially the bubbles). Additionally:
- In line `109`, I call `set_pixels_per_point` this scales up the UI. `4.0` worked for screen captures, though for general use, you will probably want something a touch lower.
- We need a `ScrollArea` in the UI (line `111`) to make viewing data for the dozens of balls in the simulation more practical.
- You can iterate over the ECS entities satisfying the initial query, with a simple for loop (line `115`).
Next, we look at the `draw_ball_ui_data` function called within that last loop.
## 🫧 Individual Bubble Updates
Another advantage of using the `uom` crate for handling physical quantities is formatting of those values for output, which we use in the `draw_ball_ui_data` function (`src/systems`):
```rust
fn draw_ball_ui_data(
ui: &mut Ui,
entity: Entity,
position: &Position,
bubble_velocity: &Velocity,
circle_mesh: &CircleMesh,
) {
let m = Length::format_args(length::meter, Abbreviation);
let m_s = VelocityUnit::format_args(velocity::meter_per_second, Abbreviation);
CollapsingHeader::new(format!(
"Entity Generation:ID {}:{}",
entity.generation(),
entity.index()
))
.default_open(false)
.show(ui, |ui| {
ui.horizontal(|ui| {
ui.label("Position");
ui.label(format!(
"x: {:.2}, y: {:.2}",
m.with(position.0.x),
m.with(position.0.y)
))
});
// TRUNCATED...
});
}
```
### Quantity Formatting
To select preferred formatting, in lines `55` and `56`, we add unit formatting for metre and metre per second quantities. These uom format args incorporate type checking, so you would get a compile-time error if you tried to format a length quantity using metres per second, for example.
Notice, in for example, in lines `67`-`70` that we can use standard Rust formatting arguments with the `uom` format arg to specify the precision we want position output data with. Here, the `{:.2}` format specifiers indicates we want to round the position values to two decimal places.
### ECS Entity Generations and IDs
ECS entities are not a lot more than an integer ID and a generation. The generation provides a mechanism for reusing IDs. For example, the first bubble spawned might have ID `0` and generation `1`. If we then despawned that bubble from the ECS, the next bubble can re-use ID `0`, which is now free. However, the ECS would give it a generation of `2`, so it can be distinguished from the earlier one.
We access, both `generation` an `id` from the Bevy ECS `Entity` struct calling `.generation()` and `.index()` in lines `59` and `60`.
## ✍🏽 Draw UI System
The system for actually drawing the DevTools panel, using `egui` is a little simpler — we just need to call `egui_macroquad::draw`:
```rust
pub fn draw_dev_tools_system() {
egui_macroquad::draw();
}
```
## 📆 Bringing it all together: ECS Schedule
I added the two new systems to the Bevy ECS schedule, to give us some control over the order Bevy ECS runs them in (`src/main.rs`):
```rust
let mut playing_schedule = Schedule::default();
playing_schedule
.configure_sets(
(
ScheduleSet::BeforeSimulation,
ScheduleSet::Simulation,
ScheduleSet::AfterSimulation,
)
.chain(),
)
.add_systems(
(
create_ball_physics_system,
(
update_dev_tools_system,
draw_balls_system,
draw_dev_tools_system,
)
.chain(),
)
.chain()
.in_set(ScheduleSet::BeforeSimulation),
)
.add_systems(step_physics_engine_system.in_set(ScheduleSet::Simulation))
.add_systems(
(
update_balls_system,
spawn_new_ball_system,
end_simulation_system,
)
.in_set(ScheduleSet::AfterSimulation),
);
```
With Bevy ECS, schedule systems grouped into a tuple will run in parallel. Tacking `.chain()` onto the end of the tuple tells the ECS that you want the systems to run in series, in the order of appearance.
## 🏁 What Next?
I have the basic, minimal DevTools panel working now. In terms of extensions and where to go next, I am considering:
- adding a wireframe view mode, with toggle, to show/hide the Rapier colliders;
- buttons for pausing, stepping and restarting the simulation from the dev panel tool; and

1,878,318 | How IaC can streamline the Infrastructure & Configuration | In today's fast-paced digital landscape, the ability to quickly and reliably deploy infrastructure is... | 0 | 2024-06-05T17:18:17 | https://dev.to/rgupta87/how-iac-can-streamline-the-infrastructure-configuration-44d5 | iac, terraform, infraprojectmanagement, devops | In today's fast-paced digital landscape, the ability to quickly and reliably deploy infrastructure is critical for product's success. As a Technical Project Manager, I've got a chance to transformative power of Infrastructure as Code (IaC) tools in streamlining infrastructure management and subsequently helped the organization in healthy infra setup and successful project delivery. In this article, I’ll explore the concept of IaC, discuss popular IaC tools, and share insights from a recent project where we successfully implemented IaC.
**<u>What is Infrastructure as Code (IaC)?</u>**
First lets understand some basics about IaC. Infrastructure as Code (IaC) is a practice where infrastructure configurations are written and managed as code. In overall, this approach allows for the automation of infrastructure provisioning & management, enabling consistency, scalability and automate the repeatability. By using infrastructure as code, engineers & designers can version control their configurations changes, enhance collaboration & communication, and deploy infrastructure changes with greater confidence & security.
**<u>Popular IaC Tools:</u>**
In the market, there are several tools that have emerged as leaders in the IaC space. Each of them offering unique features and benefits. Here are few widely used IaC tools in the market:
- **Terraform**: This is an open-source tool developed by HashiCorp, Terraform enables infrastructure provisioning across various cloud providers. It uses a declarative language to define infrastructure resources and supports modular configurations.
- **AWS CloudFormation**: Its a service by Amazon Web Services cloud platform. AWS CloudFormation allows users to define and provision AWS infrastructure using JSON or YAML templates. It can easily integrates seamlessly with other AWS services.
- **Ansible**: One of the most popular configuration management tool that also supports infrastructure provisioning. Ansible uses a simple, agentless approach, making it easy to set up and use.
- **Pulumi**: Another IaC tool that supports multiple cloud providers. This tool allows users to write infrastructure code in familiar programming languages like TypeScript, Python, and Go.
**<u>IaC in Implementation: A Project Case Study</u>**
In a recent project, team faced the challenge of managing complex, multi-environment infrastructure. We decided to adopt Terraform due to its provider-agnostic nature, easily integration with cloud platform and strong community support. Here’s how we implemented IaC:
**<u>Overall Architecture Diagram (in text format)</u>**
**<u>IaC Implementation Steps</u>**
- **Requirement gathering & Analysis**: Firstly team has started gathering requirements from business, did the feasibility study and strategize how we can implement the infrastructure for each development, staging, production environment. Identified the resources needed (such as VMs, databases, networks). List down the overall scope, divide into smaller breakdown, calculate the required talents (engineers and designers) and finally the budget required. Presented to the management for the project initiation and budget approval.
- **Defining the Infrastructure**: Based on the agreed scope, we started writing the Terraform configuration files to define our infrastructure. Each environment had its own set of configuration files, allowing for isolation and customization. Worked with the team to design and implement within the agreed timelines.
- **Version Control**: One of the critical activity to control the various versions of configuration setup. We stored our Terraform code in a Git repository, enabling version control and collaboration among team members.
- **Continuous Integration/Continuous Deployment (CI/CD)**: Most important steps to automate the integration and deployment cycles for every new version release. We integrated Terraform with our CI/CD pipeline using Jenkins. Every change to the infrastructure code triggered a pipeline that validated and applied the changes.
- **Monitoring**: Once the deployment is done, it is always important to monitor the setup and address immediately in case of any issue. Post-deployment, we used Terraform's state management to keep track of the infrastructure, configuration and made use of monitoring tools like Prometheus to ensure everything was running smoothly.
**<u>Benefits After IaC Implementation:</u>**
- **Reduced Errors**: With the help to automation, we minimized the manual intervention and therefore reduced the likelihood of errors.
- **Scalability**: This IaC implementation allowed us to scale our infrastructure effortlessly based on the demands and business needs.
- **Improved Consistency**: By defining infrastructure as code setup, we ensured that every environment was consistent and reproducible.
- **Collaboration**: With the help of version control, we noticed far better co-ordination within the team, which subsequently facilitated better collaboration and code reviews. This leads to higher quality infrastructure code with less errors.
- **Reduced Operation Cost** - With automation, we have received significant reduction in operation cost (15%) and shoot-up the overall profit for the organization.
**Conclusion!**
I must say implementing Infrastructure as Code has been a game-changer in my tech project management toolkit. The ability to define, provision, and manage infrastructure through code has brought about unprecedented efficiency and reliability. I encourage my fellow project managers to explore IaC tools and consider integrating them into their projects for a more streamlined and scalable infrastructure management process.

Whether you're collecting... | 0 | 2024-06-05T17:13:36 | https://dev.to/ianoliv/how-to-create-a-web-crawler-with-puppeteer-and-bun-4hmh | webdev, javascript, programming, tutorial | Web crawling is a powerful technique used to gather data from websites. Whether you're collecting data for research, monitoring prices, or scraping content, building a web crawler can be incredibly useful. In this post, I'll walk you through the process of creating a web crawler using Puppeteer and Bun, two popular JavaScript tools.
### Introduction to Puppeteer and Bun
Puppeteer is a Node.js library that provides a high-level API to control headless Chrome or Chromium browsers. It's perfect for web scraping and automating browser tasks.
Bun is a fast, modern JavaScript runtime similar to Node.js but optimized for speed and performance. It's designed to work seamlessly with existing JavaScript libraries.
### Step-by-Step Guide to Building a Web Crawler
**Step 1**: Setting Up Your Environment
First, ensure you have Node.js installed. Then, install Bun by following the instructions on the Bun website.
Next, create a new project directory and initialize it with Bun:
```sh
# Copy code
mkdir web-crawler
cd web-crawler
bun init
```
**Step 2**: Installing Puppeteer
Install Puppeteer using Bun:
```sh
# Copy code
bun add puppeteer
bun node_modules/puppeteer/install.js # -> the secret sauce
```
**Step 3**: Writing the Web Crawler Script
Create a new JavaScript file, crawler.js, and start by importing Puppeteer:
```javascript
// Copy code
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://example.com');
// Extract data
const data = await page.evaluate(() => {
return document.querySelector('h1').innerText;
});
console.log(data);
await browser.close();
})();
```
In this script, we launch a headless browser, navigate to a website, and extract the text of an <h1> element.
**Step 4**: Running the Script
Run your script using Bun:
```sh
## Copy code
bun run crawler.js
## You should see data printed in your terminal.
```
### Conclusion
Creating a web crawler with Puppeteer and Bun is straightforward and efficient. Puppeteer handles the browser automation, while Bun provides a fast and modern runtime for your JavaScript code. This combination makes for a powerful tool in your web scraping toolkit.
For more advanced use cases, you can extend your script to handle navigation, interact with page elements, and scrape more complex data structures. Happy crawling!

1,878,323 | 2024 Guide to Infinite Scrolling in React/Next.js | Ever saw how posts keep on displaying on the feed section of X (Twitter) or Instagram if you keep... | 0 | 2024-06-05T17:00:43 | https://sumansourabh.in/2024-guide-to-infinite-scrolling-in-react-next-js/ | nextjs, tutorial, react, frontend | Ever saw how posts keep on displaying on the feed section of X (Twitter) or Instagram if you keep scrolling down?
That “thing” is called infinite scroll.
## What is Infinite Scrolling?
Infinite scrolling is a technique or approach in web development where more resources are fetched and displayed on the page as the user scrolls down.
For example, in social media platforms such as X (Twitter), if you scroll down in the feed, more posts will display to you.
This approach is helpful when you have a lot of resources to show on the page and you do not want to fetch them all at once and slow down the application.
## How to use it in React/Next.js?
Of course, you can build your own infinite scrolling component from scratch but in many cases, it is better to use a library.
On [Libertas](https://libertas-vert.vercel.app/), I have used a popular library called react-infinite-scroll-component.
This library has an inbuilt component which does the behaviour of infinite scrolling for us. We just have to dump our code of fetching multiple items inside this code.
> Feedback is appreciated about this approach.
## Understanding the Scenario
I have a [feed page](https://libertas-vert.vercel.app/feed) on Libertas where I show all the posts that the users have created. It is just like how different items are displayed on the feed page on Reddit, X, Medium, Nike and other such platforms.
Our aim is to fetch some posts/items when the page loads fully. When the user scrolls to the bottom of the page or the last item that was fetched when the page loaded, we trigger a GET request to fetch more posts.
This process repeats until all the items are fetched, which may not be possible if the items are huge in numbers (>500 items). Hence, the name “Infinite scroll”! Users will get exhausted, won’t they?
## Steps to Implement `react-infinite-scroll-component`
Below are the steps where I mention how I added this component into Libertas.
### Install the package
**For npm:**
```
npm i react-infinite-scroll-component
```
**For yarn:**
```
yarn add react-infinite-scroll-component
```
Copy and paste the below code for infinite scroll in Libertas
```
<InfiniteScroll
dataLength={items.length} //This is important field to render the next data
next={fetchData}
hasMore={true}
loader={<h4>Loading...</h4>}
endMessage={
<p style={{ textAlign: 'center' }}>
<b>Yay! You have seen it all</b>
</p>
}
>
{items}
</InfiniteScroll>
```
### Understanding the props
According to `react-infinite-scroll-component` [GitHub page](https://github.com/ankeetmaini/react-infinite-scroll-component):
> **dataLength:** set the length of the data. This will unlock the subsequent calls to next.
> **next:** a function which must be called after reaching the bottom. It must trigger some sort of action which fetches the next data. The data is passed as children to the `InfiniteScroll`component and the data should contain previous items too. e.g. Initial `data = [1, 2, 3]` and then next load of data should be `[1, 2, 3, 4, 5, 6]`.
> **hasMore:** it tells the `InfiniteScroll` component on whether to call next function on reaching the bottom and shows an `endMessage` to the user
> **loader:** you can send a loader component to show while the component waits for the next load of data. e.g. `<h3>Loading…</h3>` or any fancy loader element
> **endMessage:** this message is shown to the user when he has seen all the records which means he’s at the bottom and hasMore is false
> **items:** The list of items to be fetched and displayed on the page. In case of Libertas, the `{items}` are the list of posts created by users.
### Further Steps:
1. Fetch some posts when the page loads
2. Display the list of posts on the page
3. Make a slight change on the API GET request (Backend) to fetch the next list of posts
4. Fetch the next list of posts on the frontend
### Final code:
```
const [posts, setPosts] = useState([]);
const [count, setCount] = useState(4);
const [currentCount, setCurrentCount] = useState(null);
const [total, setTotal] = useState(null);
const fetchPosts = async () => {
const data = await fetchAllPosts(count);
console.log(data?.data?.data);
setPosts(data?.data?.data);
setCurrentCount(data?.data?.currentLength);
setTotal(data?.data?.total);
setCount(count + 2);
};
useEffect(() => {
fetchPosts();
}, []);
return (
<Stack>
<InfiniteScroll
dataLength={posts?.length} //This is important field to render the next data
next={fetchPosts}
hasMore={currentCount !== total}
loader={<h4>Loading...</h4>}
endMessage={
<p style={{ textAlign: "center" }}>
<b>Yay! You have seen it all</b>
</p>
}
>
{posts.map((post) => (
<PostComponent
key={post._id}
post={post}
id={post._id}
handleUpvote={() => handleVote(upvoteAPost, post._id)}
handleDownvote={() => handleVote(downvoteAPost, post._id)}
individualView={false}
/>
))}
</InfiniteScroll>
</Stack>
);
```
### Breakdown of the code
I created a GET request named `fetchAllPosts `which fetches 4 posts when the page loads. I used map function to list all the posts inside the `InfiniteScroll `component.
In order to fetch the next set of posts, I had to make a slight change in the API of the request (written in Node.js) where I fetch the posts. That change was adding a count or a number that will tell me how many posts to fetch. When the user scrolls down the web page, those number of posts will be fetched from the database and displayed.
```
// @desc Get all the posts
// @route GET /api/user/posts
// @access Public
const getAllPosts = asyncHandler(async (req, res, next) => {
const { count } = req.query;
const posts = await PostModel.find();
const postsToDisplay = posts.reverse().slice(0, count);
res.status(200).json({
success: true,
total: posts.length,
currentLength: postsToDisplay.length,
data: postsToDisplay,
});
});
```
I added a count variable which comes from the query in the URL just like this: `api/v1/posts?count=4`. This fetches only 4 posts.
3. Now, things were easier. Time to add the frontend code to fetch the next set of posts.
```
const [posts, setPosts] = useState([]);
const [count, setCount] = useState(4);
const [currentCount, setCurrentCount] = useState(null);
const [total, setTotal] = useState(null);
const fetchPosts = async () => {
const data = await fetchAllPosts(count);
setPosts(data?.data?.data);
setCurrentCount(data?.data?.currentLength);
setTotal(data?.data?.total);
setCount(count + 2);
};
```
The above code first fetches 4 posts (coming from the initial value of the count state variable).
It also sets the current count or the current length of the posts which will be 4 on the first fetch.
The value of total no. of posts is also set as it is being returned in the API response.
Lastly, the value of count updates to 6, which will be used for the next fetch function call.
The above values are used in the `InfiniteScroll `component below:
```
<InfiniteScroll
dataLength={posts?.length} //This is important field to render the next data
next={fetchPosts}
hasMore={currentCount !== total}
loader={<h4>Loading...</h4>}
endMessage={
<p style={{ textAlign: "center" }}>
<b>Yay! You have seen it all</b>
</p>
}
>
{posts.map((post) => (
<PostComponent
key={post._id}
post={post}
id={post._id}
handleUpvote={() => handleVote(upvoteAPost, post._id)}
handleDownvote={() => handleVote(downvoteAPost, post._id)}
individualView={false}
/>
))}
</InfiniteScroll>
```
### Working of `InfiniteScroll `component
In the above code, the list of posts are displayed. After this:
- The value of `dataLength `gets assigned to the number of posts fetched for the first time.
- When the user scrolls down, the `hasMore `prop comes into action.
`hasMore `tells us that if it is true, initiate the function available in the next prop. In our code, when the current count or current length of the posts is not equal to the total no. of posts, call the `fetchPosts `function.
- Then `fetchPosts `is called with the updated count value of 6, then 6 posts are fetched and the value of posts array is updated. The value of `dataLength `is also updated.
- If all the posts are not fetched, the content inside the loader prop is displayed after the latest post. Ideally, this can be a [skeleton component](https://www.smashingmagazine.com/2020/04/skeleton-screens-react/) or a loading text/animation.
- If `hasMore `is false or in other words, all the posts are fetched from the database, the element inside the `endMessage `prop is displayed after the last post.
## Conclusion
**Infinite scroll** is a good approach to make a website perform a bit better but like everything in tech, this approach is not for every website. It mostly depends on the type of platform and the type of users (target audience).
I added this to [Libertas](https://medium.com/@sumsourabh14/reddit-alternative-heres-what-i-am-building-sort-of-2b8044842952), the online discussion platform built with Next.js, because the users will create multiple posts and it will be a headache/nightmare to render everything at once on a single web page. Wouldn’t it?
## Wondering what is Libertas?
**Libertas is an online discussion website** for users where they can just discuss. **Discuss freely. No rules, no moderators.**
You can just look at the posts that the users have created or if you feel hooked, you can sign up and start creating! You can upvote/downvote posts and comment on them. If you forget your password, there is an option reset it too!

---
## What are all options possible?
You've got various options available to safely access your local environment from a distance. Here, we'll explore three notable options, discussing how to set them up, their security implications, as well as their advantages and disadvantages:
1. Port forwarding
2. Cloudflare Tunnel
3. Reverse SSH Tunneling
---
## Port forwarding
Probably the most prevalent option (unfortunately) today is port forwarding. The idea is to open a port on your router to the outside world so that anyone can access it.
### How do you open a port on the router?
Before I explain how to open a port on the router, I would just like to say that there is a possibility that the ISP does not allow you to do this because their network uses [CGNAT](https://en.wikipedia.org/wiki/Carrier-grade_NAT) (which means that you share an IP address with several users). If you are not sure, it would be best to contact the ISP first and see if port forwarding is possible, if not, if they can provide you with that option (sometimes it is free, sometimes they will charge you extra if you want this feature).
So let's continue. In most cases, you will have to connect via a cable (not via WiFi), since most routers today have the option to log in to the Admin panel via WiFi.
1. Open "http://192.168.0.1/" in your browser and log in to the admin panel
2. Go to the "Port forwarding" page
3. Enter which port you want to open (and which port to watch when someone enters that open port)
4. Save the change and that's it. When you go to "http://your-ip:open-port" you should see your localhost
If it does not work for you, it is very possible that your ISP does not support opening ports and you will have to choose another option.
### Conclusion
This was straightforward, but... Opening a port through a router means that anyone in the world will be able to access your local machine, potentially resulting in security breaches. From facing DDoS attacks targeting your IP address, which could prompt your IPS to block your internet, to the risk of someone hacking into your local server for network monitoring purposes, the complications are countless. While this option may be the simplest, it's undoubtedly the least secure, and I would not recommend it.

# Cloudflare Tunnel
[Cloudflare](https://www.cloudflare.com/) is a web infrastructure and website security company that offers CDN services, DDoS mitigation, internet security, and distributed domain name server services. It serves as a reverse proxy for websites, caching website data, and filtering out threats to enhance website loading speed and defend against attacks.
Cloudflare also provides the option to tunnel a local service through their servers, effectively and securely exposing the local server to the outside world.
It's crucial to understand that using Cloudflare requires you to have a domain set up with them, making it a prerequisite for this functionality to work.
### How do you configure Cloudflare Tunnel?
1. Log in to [Cloudflare](https://www.cloudflare.com/)
2. Go to the [Cloudflare Zero Trust](https://one.dash.cloudflare.com/) section in your dashboard
3. Go to "Networks -> Tunnels" page and select "Cloudflare" as connector
4\. Enter the name of your tunnel
5\. Choose your OS (recommended to use Docker). I will use Docker, so when he selects the option run the tunnel script on your local server
6\. Choose which subdomain and domain you want to connect to the localhost port
7\. Save and if you did everything like I did, you will see that your tunnel is "healthy" and when you go to the entered subdomain, you should see your localhost
### Conclusion
Although owning a domain (typically around $10 per year) is a requirement, using Cloudflare Tunnel remains one of the top choices for most individuals. It offers extensive flexibility, security features, and a wide range of options such as analytics, DDoS protection, and caching, all of which come at no cost.
However, it's essential to be aware that Cloudflare Tunnel does not support streaming, as doing so may lead to Cloudflare banning your account.
It's worth noting that Cloudflare hides your private IP address behind its network, significantly enhancing your security compared to directly opening ports on your router, where your IP address is exposed to everyone.
---
## Reverse SSH Tunneling
Reverse SSH Tunneling is a method used to establish a secure connection from a remote server back to a local machine.
It's worth noting that you'll need a server from a VPS provider (I recommend [Hetzner](https://hetzner.cloud/?ref=Vms0hnsG0ytf)) through which you'll tunnel traffic to your local server. This technique is highly secure because it leverages the fundamental SSH protocol, encrypting all traffic and keeping your local IP address hidden.
### How do you configure Reverse SSH Tunneling?
1. Generate an SSH key on the local server using ssh-keygen
2. Transfer the public SSH key from the local server to the remote server and append it to the "[authorized_keys](https://www.ssh.com/academy/ssh/authorized-keys-file)" file. This enables the local server to connect to the remote server via SSH without requiring a password, as the SSH key serves for authentication
3. Configure NGINX on the remote server to act as a proxy, redirecting traffic from a specified port or domain to another port. Optionally, you can set up a DNS entry for your domain. Below is an example NGINX configuration:
```
server {
listen 80;
server_name localhost.darkotodoric.com;
location / {
proxy_pass http://localhost:1337/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Protocol $scheme;
proxy_set_header X-Forwarded-Host $http_host;
}
error_log /var/log/nginx/localhost.darkotodoric.com_error.log;
access_log /var/log/nginx/localhost.darkotodoric.com_access.log;
}
```
4\. On the local server, initiate SSH tunneling with the following command:
```
ssh -R 1337:localhost:80 remote_user@remote_server_ip
```
5\. Assuming all configurations are correct, traffic from "localhost.darkotodoric.com" should now be forwarded to "localhost:80"
To ensure a stable connection, especially in the event of network interruptions, consider setting up SSH tunneling as a service on Linux. Here's an example of how the service should be configured:
```
[Unit]
Description=autossh
Wants=network-online.target
After=network-online.target
[Service]
Type=simple
ExecStart=/usr/bin/ssh -o "StrictHostKeyChecking=no" -o "ServerAliveInterval 10" -o "ServerAliveCountMax 3" -o "ExitOnForwardFailure=yes" -T -N -R1337:localhost:80 remote_user@remote_server_ip
Restart=always
RestartSec=10
[Install]
WantedBy=multi-user.target
```
### Conclusion
While requiring your own remote server, "Reverse SSH Tunneling" offers a straightforward, secure, and reliable method to expose your local server to the world without any limitations.
---
# Conclusion
My advice is to avoid "Port forwarding" on the router due to potential security vulnerabilities. When considering the other two options, your choice should be guided by your specific needs and intentions. If you intend to run a local media server for streaming video content, "Reverse SSH Tunneling" is the way to go, as Cloudflare doesn't support streaming (at least not for free) through their platform. However, for any other purpose, "Cloudflare Tunnel" is an excellent solution. It's simpler to set up and comes with a host of features like analytics, security, caching, DNS configuration, DDoS protection, and more, all provided free of charge. | darkotodoric |
1,769,618 | Accessibility Breakdown | Focusable Indicators | Todays mini series of things you can do right now focuses on enhancing the accessibility (a11y) of... | 26,989 | 2024-06-05T17:00:00 | https://dev.to/devsatasurion/accessibility-break-down-focusable-indicators-1ibe | a11y, accessibledevelopment, webdev | Todays mini series of things you can do <mark>**right now**</mark> focuses on enhancing the accessibility (a11y) of focusable indicators in your application. Let's get into it:
## Why it Matters:
- **Accessibility Impact**: Clear focus indicators are crucial for users with disabilities to navigate effectively, ensuring they can identify interactive elements.
- **User Experience**: Proper focus indicators prevent confusion and empower users to interact with your application confidently.
---
## Quick Check:
- **Manual Scan**: Quickly review your application for interactive elements that may lack visible focus indicators using **tab navigation**. You may use Enter or Spacebar to activate buttons or links.
- **Automated Tools**: Use accessibility testing tools such as [Axe](https://chromewebstore.google.com/detail/axe-devtools-web-accessib/lhdoppojpmngadmnindnejefpokejbdd?utm_source=deque.com&utm_medium=referral&utm_campaign=axe_hero) or [WAVE](https://chromewebstore.google.com/detail/wave-evaluation-tool/jbbplnpkjmmeebjpijfedlgcdilocofh) to identify elements with missing or inadequate focus indicators.
- **Screen Reader**: Sometimes a screen reader might use different keys to activate focusable elements so ensure you check using both with and without a screen reader.
---
## Quick Fixes:
- **Enhance Focus Styles**: Ensure interactive elements have clear and distinct focus styles, making them visible and easy to identify. Typically this involves adding a solid color outline or changing the background color of the element.
- Avoid disabling the default focus ring provided by browsers unless you replace it with an equally visible alternative. This is particularly important for keyboard users.
- Ensure that all focusable elements have consistent focus styles across the application to maintain a uniform user experience
- For low vision or color-blind users ensure a **highly** visible focus indicator, such as a thick outline or contrasting color is used so there is no confusion.
- **Focus Management**: Implement proper focus management to ensure that focus moves logically through focusable elements, enhancing keyboard navigation. An example would be when a user clicks a button that opens a modal ensuring that the focus moves into the modal dialog and on close of the modal moves back to the button.
```react
const openModalButton = document.getElementById('openModalButton');
const closeModalButton = document.getElementById('closeModalButton');
const modal = document.getElementById('modal');
openModalButton.addEventListener('click', () => {
modal.style.display = 'block';
modal.setAttribute('tabindex', '-1');
modal.focus();
});
closeModalButton.addEventListener('click', () => {
modal.style.display = 'none';
openModalButton.focus();
});
```
---
## Testing
- Thoroughly test your application post-fix, using both keyboard navigation and assistive technologies like screen readers, to ensure focus indicators are visible and functional.
- Consider writing automated tests with Axe to automatically check for focus indicators as a custom rule.
```react
const customRule = `
axe.configure({
checks: [
{
id: 'focus-visible',
evaluate: function(node) {
const style = window.getComputedStyle(node);
return style.outlineStyle !== 'none' || style.boxShadow !== 'none';
},
metadata: {
impact: 'critical',
messages: {
fail: 'Focusable elements should have visible focus styles.'
}
}
}
],
rules: [
{
id: 'focus-indicator',
selector: ':focus',
enabled: true,
any: ['focus-visible'],
tags: ['focus']
}
]
});
`;
```
By following these quick steps, you can quickly enhance the accessibility of focusable indicators in your application, contributing to a more inclusive online environment for all users. Accessibility is an ongoing journey, so start making a positive impact today!🌟

---
A bankable Restaurant business plan is a crucial first step for restaurant entrepreneurs for several reasons. A bankable plan is not just a document but a strategic tool that can set the stage for a successful restaurant venture. It's an essential first step that no restaurant entrepreneur should overlook.
The Purpose of Plans,
**Attracting Investors:** A well-crafted Restaurant business plan is often the first thing investors want to see. It provides a comprehensive overview of your restaurant concept, target market, and financial projections. This document serves as a roadmap, outlining how the business will become profitable. By presenting a solid bankable plan, entrepreneurs can demonstrate they've done their homework and convince investors that their restaurant is a worthy investment.
**Regulatory Approvals:** Operating a restaurant requires various licenses and permits from local health departments, liquor boards, and other regulatory bodies. A detailed restaurant business plan helps demonstrate to these regulators that you understand the industry and have considered all necessary regulations in your planning.
**Feasibility Assessment:** An external independent agency often conducts a feasibility study to determine the viability of a restaurant in a specific location. The plan provides the necessary information for this assessment, helping to identify potential challenges and opportunities in the market.
**Avoiding Failure and Bankruptcy:** The restaurant industry is notoriously competitive, with a high failure rate. A thorough plan includes a SWOT analysis (Strengths, Weaknesses, Opportunities, Threats) that helps entrepreneurs anticipate problems and devise strategies to mitigate risks, thereby increasing the chances of success and avoiding potential bankruptcy.
**Attracting Talent:** A compelling restaurant business plan can also help attract talented chefs, managers, and staff. It shows that the restaurant has a clear direction and vision, making it an attractive place to work.
**Financial Feasibility:** Lastly, a plan is essential for assessing the financial feasibility of the restaurant. It includes detailed financial projections, providing a clear picture of the expected revenue, costs, and profitability. This information is crucial for both the entrepreneur and potential investors to understand the financial implications of the venture.
## Essential Parts of a Restaurant Business Plan
### 1. Executive Summary
The executive summary is the first section of your restaurant business plan. It provides a high-level overview of your restaurant concept, target market, and financial projections. This section should be concise, compelling, and designed to entice the reader to learn more about your restaurant.
Your executive summary should include your restaurant’s name, location, and the type of cuisine you plan to serve. It should also outline your unique selling proposition—what sets your restaurant apart from the competition. Additionally, you should provide a brief overview of your financial projections, including your expected revenue, costs, and profitability.
Remember, the executive summary is often the first impression potential investors get of your restaurant, so make it count!
### 2. Menu and Services
Your menu is the heart of your restaurant, so it deserves a section of its own in your business plan. This section should provide a detailed description of your menu items, including the ingredients, preparation methods, and pricing.
You should also discuss any additional services your restaurant will offer, such as catering or delivery. If you plan to serve alcohol, include information about your liquor license and your plans for a bar area.
There are many value-added services you can add. Here are a few to consider:
**Digital Presence:** In today’s digital age, having a strong online presence is crucial. A user-friendly online food ordering website, [multi restaurant delivery software](https://www.kopatech.com/multi-restaurant-delivery-software), and active social media profiles can significantly boost a restaurant’s reach. Additionally, partnering with popular food delivery platforms can ensure the restaurant’s offerings are accessible to customers who prefer dining at home.
**Loyalty Programs:** A well-structured loyalty program can be a game-changer for a restaurant business. It encourages repeat visits and fosters a sense of belonging among customers. By offering rewards such as discounts, free meals, or priority reservations, restaurants can build a loyal customer base. This not only increases revenue but also turns customers into brand ambassadors who spread positive word-of-mouth.
**Catering Services:** Expanding into catering services can open up new revenue streams. Whether it’s corporate events, weddings, or parties, there’s always a demand for quality food. Offering a range of customizable menus and packages can cater to diverse customer needs. It also provides an opportunity to showcase the restaurant’s culinary skills to a broader audience, thereby increasing brand visibility.
### 3. Company Description
The company description provides detailed information about your restaurant. This section should include your restaurant’s legal structure (e.g., sole proprietorship, partnership, corporation), ownership information, and a detailed description of your restaurant's concept.
You should also describe the ambiance of your restaurant, the seating capacity, and the type of service your customers can expect (e.g., full service, fast-casual, takeout). Additionally, you should discuss any plans for future growth, such as opening additional locations or expanding your menu.
### 4. Market Analysis
The market analysis section of your restaurant business plan involves a detailed examination of your target customers, the local restaurant market, and your competition. This section should demonstrate that there is a viable market for your restaurant and that you have a clear understanding of your competition.
Your market analysis should include demographic information about your target customers, such as age, income level, and dining preferences. You should also provide information about the size and growth trends of your local restaurant market.
### 5. Organization and Management
This section of your restaurant business plan should outline your restaurant’s organizational structure and provide information about the ownership and management team. You should include an organizational chart showing the roles and responsibilities of each member of your team.
You should also provide detailed bios of your management team, highlighting their experience in the restaurant industry. If you plan to hire additional staff, include job descriptions and hiring criteria for each role.
### 6. Marketing and Sales Strategy
This section of your restaurant business plan should outline your strategies for attracting and retaining customers. You should discuss your branding and advertising strategies, as well as your plans for promotions and customer loyalty programs.
Your marketing strategy should also include a detailed plan for your restaurant’s grand opening. This could involve a soft opening for friends and family, a grand opening event for the public, and special promotions for your first few weeks of operation.
### 7. Funding Request
If you’re seeking funding for your restaurant, this section of your plan should outline your current funding requirements, future funding requirements over the next five years, how you will use the funds, and the types of funding you would consider.
You should provide a detailed breakdown of how you plan to use the funds, whether it’s for purchasing equipment, renovating your restaurant space, or covering operating expenses until you reach profitability.
### 8. Financial Projections
The financial projections section of your restaurant business plan should provide a forecast of your restaurant’s financial performance over the next three to five years. This section should include projected income statements, cash flow statements, and balance sheets.
Your financial projections should be realistic but optimistic. They should demonstrate that your restaurant will be profitable and provide a good return on investment for any potential investors.
## Importance of Technology in Restaurant Business Plan
Discuss the following points:
1. An [online food ordering system](https://www.kopatech.com/online-food-ordering-system) can be a game-changer in the restaurant industry, making businesses more modern and profitable. It revolutionizes the way restaurants operate, bringing numerous benefits.
2. Managing a fleet of delivery vehicles for timely delivery, enhancing customer satisfaction. Briefly discuss GPS tracking and route optimization to ensure efficient deliveries, reduce fuel costs, and improve service speed.
3. Efficient utilization of manpower and delivery staff is another topic. Discuss Online systems that automate many tasks, freeing up staff to focus on providing excellent customer service. Consider how it can allow better scheduling, ensuring peak times and smooth deliveries.
### Importance of Outsourcing for Efficiency and Quality
**Software Providers:** Restaurants require various software solutions for smooth operations, such as Point of Sale (POS) systems, inventory management systems, customer relationship management (CRM) software, and more. These systems help streamline operations, improve efficiency, and provide valuable insights for decision-making. However, developing these systems in-house requires significant time, resources, and technical expertise. By outsourcing to experienced software providers, restaurants can get customized solutions that fit their unique needs. These providers also offer training and support, ensuring the restaurant staff can effectively use the software.
**Delivery System:** In the digital age, an online food delivery system is a must for any restaurant. It allows customers to place orders from the comfort of their homes, thereby increasing the restaurant's reach and revenue. However, developing and maintaining such a system can be complex and time-consuming. Therefore, it makes sense to outsource this to a specialized service provider. They have the expertise to develop a user-friendly and efficient system that meets the restaurant's specific needs. They also provide ongoing support and updates to ensure the system remains up-to-date and secure. This allows the restaurant to focus on what they do best - preparing delicious food.
**Food and Beverage Sourcing:** The quality of food and beverages served is crucial to a restaurant's success. Therefore, it's important to source high-quality ingredients. However, finding reliable suppliers can be challenging and time-consuming. By outsourcing food and beverage sourcing to a specialized service provider, restaurants can ensure they get the best ingredients at competitive prices. These providers have established relationships with a wide network of suppliers and can negotiate better deals. They also handle logistics and quality control, ensuring the ingredients are delivered fresh and on time.

However, the console API offers... | 0 | 2024-06-05T16:40:17 | https://10xdev.codeparrot.ai/debugging-beyond-console-log-in-javascript | javascript, debugging, console, webdev |
Most JavaScript developers are familiar with the basic `console.log()`. However, the console API offers many other methods that can be incredibly useful in both development and debugging workflows.
### Basic `console.log()`
Let's start with the basic `console.log()` which is used to print messages to the console.
```javascript
console.log("Hello, World!");
```
This is the most commonly used method for debugging and logging messages.
### `console.error()`
`console.error()` is used to output error messages. It helps in distinguishing errors from regular log messages in the console.
```javascript
console.error("This is an error message");
```
This will print the message in red, making it stand out.
### `console.warn()`
`console.warn()` outputs warning messages. These are less severe than errors but still important to notice.
```javascript
console.warn("This is a warning message");
```
Warning messages appear in yellow, which helps to differentiate them from regular logs and errors.
### `console.info()`
`console.info()` is used for informational messages.
```javascript
console.info("This is an informational message");
```
It behaves similarly to `console.log()` but can be useful for categorizing log messages.
### `console.debug()`
`console.debug()` is used for debugging purposes and is often hidden by default in many browsers' console settings.
```javascript
console.debug("This is a debug message");
```
To enable it make sure that `Verbose` is checked in the top bar.
### `console.table()`
`console.table()` allows you to display data as a table. This can be very helpful when working with arrays or objects.
```javascript
const users = [
{ name: "Alice", age: 25 },
{ name: "Bob", age: 30 },
{ name: "Charlie", age: 35 },
];
console.table(users);
```
This will print the `users` array as a table, making it easier to read.
### `console.time()` and `console.timeEnd()`
These methods are used to measure the time taken for a piece of code to execute.
```javascript
function processData() {
console.time("processData");
// Simulating a time-consuming process
for (let i = 0; i < 1000000; i++) {
// Process
}
console.timeEnd("processData");
}
processData();
```
`console.time("processData")` starts the timer, and `console.timeEnd("processData")` stops it, printing the time elapsed in milliseconds. This can help identify bottlenecks in code and improve performance.
### `console.count()`
`console.count()` is used to count the number of times a code block is executed.
```javascript
for (let i = 0; i < 5; i++) {
console.count("Counter");
}
```
This will print the count each time the loop runs.
### `console.group()` and `console.groupEnd()`
These methods allow you to group together multiple log messages.
```javascript
console.group("User Details");
console.log("Name: Alice");
console.log("Age: 25");
console.groupEnd();
```
This creates an expandable group in the console. You can also create nested groups for better organization.
### `console.assert()`
`console.assert()` writes a message to the console only if an assertion is false.
```javascript
const x = 10;
console.assert(x > 10, "x is not greater than 10");
```
Since `x` is not greater than 10, the message will be printed.
### Styling Console Logs
You can style console log messages using CSS.
```javascript
console.log("%cThis is a styled message", "color: blue; font-size: 20px;");
```
The `%c` is a placeholder for the CSS style string that follows.
### Best Practices
1. **Use Appropriate Methods:** Use `console.error()` for errors, `console.warn()` for warnings, and so on. This helps in filtering messages in the console.
2. **Remove Logs in Production:** Ensure that you remove or disable console logs in production code to avoid clutter and potential performance issues.
3. **Group Related Logs:** Use `console.group()` and `console.groupEnd()` to keep related logs together.
### Conclusion
Next time you’re knee-deep in code and need to debug, give these methods a try. They can make your life easier and your debugging sessions more efficient. So, go ahead, experiment with these in your next project and see the difference they can make.
For more detailed information, you can refer to the [MDN Web Docs on console](https://developer.mozilla.org/en-US/docs/Web/API/Console).

1,878,314 | Difference between Asynchronous Javascript and Synchronous Javascript | Synchronous JavaScript: In synchronous JavaScript, code is executed sequentially, one line at a time.... | 0 | 2024-06-05T16:39:51 | https://dev.to/sloppenheimer/difference-between-asynchronous-javascript-and-synchronous-javascript-174c | javascript, webdev, beginners | Synchronous JavaScript:
In synchronous JavaScript, code is executed sequentially, one line at a time. Each operation blocks the execution of subsequent operations until it completes. This means that if one operation takes a long time to finish, it can delay the execution of other operations, potentially causing the application to become unresponsive. Synchronous code is straightforward to read and write, as it follows a linear flow, making it easier to reason about the program's behavior.
Asynchronous JavaScript:
On the other hand, asynchronous JavaScript allows code to run independently of the main execution thread. Asynchronous operations, such as fetching data from a server or waiting for a user input, are initiated, but the program doesn't wait for them to finish before moving on to the next operation. Instead, it registers a callback function to be executed once the asynchronous task is complete. This non-blocking behavior ensures that the application remains responsive, even when performing time-consuming tasks.
Example:
Consider the scenario of fetching data from a server. In synchronous JavaScript, the code would wait for the server to respond before proceeding with any other tasks, potentially causing the application to freeze until the data is received. However, in asynchronous JavaScript, the code would initiate the data-fetching operation and continue executing other tasks while waiting for the server's response. Once the data is available, a callback function would be invoked to handle the retrieved data, allowing the application to remain responsive throughout the process.
Benefits of Asynchronous JavaScript:
- Improved performance: Asynchronous operations prevent the main execution thread from being blocked, resulting in a more responsive user experience.
- Better utilization of resources: By allowing multiple tasks to run concurrently, asynchronous JavaScript maximizes the utilization of CPU and memory resources.
- Enhanced scalability: Asynchronous programming is essential for handling large-scale applications that require concurrent processing of multiple tasks, such as web servers and real-time applications.
In summary, synchronous JavaScript executes code sequentially, blocking subsequent operations until each one is completed, while asynchronous JavaScript allows code to run independently, registering callback functions to handle tasks once they're finished. Understanding the differences between synchronous and asynchronous JavaScript is crucial for building efficient and responsive web applications. | sloppenheimer |
1,878,313 | Linux Package Management: A Basic Overview - DevOps Prerequisite 4 | Introduction to Linux Package Management Linux package management is a cornerstone of... | 0 | 2024-06-05T16:27:18 | https://dev.to/iaadidev/linux-package-management-a-basic-overview-4b05 | linux, devops | ### Introduction to Linux Package Management
Linux package management is a cornerstone of maintaining and administering a Linux system. It involves installing, upgrading, configuring, and removing software packages. Each Linux distribution has its package management system, which simplifies these tasks. This blog will delve into package management on Debian-based (e.g., Ubuntu) and Red Hat-based (e.g., CentOS, Fedora) systems. We will provide comprehensive, easy-to-follow examples and explanations to help even beginners understand and implement these tasks.
### What is a Package?
A package in Linux is a collection of files bundled together to provide a piece of software. This can include executables, libraries, configuration files, and documentation. Package managers handle these packages, streamlining the process of installing and maintaining software on your system.
### Package Management on Debian-based Systems
Debian-based systems, such as Ubuntu, use `apt` (Advanced Package Tool) for package management. Here’s a detailed guide on using `apt`:
#### Updating Package Lists
Before installing or upgrading packages, you should update your package lists to fetch the latest versions available from the repositories:
```bash
sudo apt update
```
This command contacts all configured repositories and downloads the latest package information.
#### Installing Packages
To install a package, use the `install` command followed by the package name. For instance, to install `curl`, a command-line tool for transferring data with URLs, you would run:
```bash
sudo apt install curl
```
#### Removing Packages
If you need to remove a package, use the `remove` command:
```bash
sudo apt remove curl
```
This command will remove the `curl` package but leave the configuration files behind. To remove a package and its configuration files, use `purge`:
```bash
sudo apt purge curl
```
#### Upgrading Packages
To upgrade all installed packages to their latest versions, use the `upgrade` command:
```bash
sudo apt upgrade
```
For a more thorough upgrade that also handles dependencies and removes obsolete packages, use `dist-upgrade`:
```bash
sudo apt dist-upgrade
```
This command ensures that all dependencies are handled correctly, even if it means installing or removing some packages.
#### Searching for Packages
To search for a package, use the `search` command:
```bash
apt search curl
```
This command will list all packages related to `curl`, allowing you to find and install software easily.
#### Showing Package Information
To get detailed information about a package, including its version, description, and dependencies, use:
```bash
apt show curl
```
This command provides a comprehensive overview of the package, helping you understand what it does and what it requires.
### Package Management on Red Hat-based Systems
Red Hat-based systems, such as CentOS and Fedora, use `yum` or `dnf` (the next-generation version of `yum`) for package management. Here’s how to use `dnf`:
#### Updating Package Lists
To update your package lists, use:
```bash
sudo dnf check-update
```
This command checks for updates to the packages installed on your system and lists available updates.
#### Installing Packages
To install a package, use the `install` command followed by the package name. For example, to install `curl`:
```bash
sudo dnf install curl
```
#### Removing Packages
To remove a package, use the `remove` command:
```bash
sudo dnf remove curl
```
This command will remove the `curl` package from your system.
#### Upgrading Packages
To upgrade all installed packages to their latest versions, use the `upgrade` command:
```bash
sudo dnf upgrade
```
This command upgrades all packages on your system to the latest versions available in your repositories.
#### Searching for Packages
To search for a package, use the `search` command:
```bash
dnf search curl
```
This command will list all packages related to `curl`.
#### Showing Package Information
To get detailed information about a package, including its version, description, and dependencies, use:
```bash
dnf info curl
```
This command provides a detailed overview of the package.
### Advanced Package Management Techniques
For more advanced users, there are additional tools and techniques for managing packages more effectively.
#### Cleaning Up
Over time, your system may accumulate unnecessary packages and cache files. To clean up, use these commands:
**Debian-based:**
```bash
sudo apt autoremove
sudo apt clean
```
`autoremove` removes packages that were automatically installed to satisfy dependencies for other packages and are no longer needed. `clean` removes all cached package files.
**Red Hat-based:**
```bash
sudo dnf autoremove
sudo dnf clean all
```
`autoremove` removes packages that are no longer needed. `clean all` removes all cached package files.
#### Managing Repositories
Repositories are servers that store software packages. Managing repositories involves adding, removing, and configuring these sources to control where your system gets its software.
**Adding a Repository (Debian-based):**
```bash
sudo add-apt-repository ppa:some/ppa
sudo apt update
```
**Adding a Repository (Red Hat-based):**
```bash
sudo dnf config-manager --add-repo=http://some-repo-url
```
#### Pinning Packages
Package pinning allows you to control the version of packages that are installed on your system.
**Debian-based:**
Create a file in `/etc/apt/preferences.d/` with the following content:
```plaintext
Package: *
Pin: release a=stable
Pin-Priority: 1001
```
This configuration ensures that packages are installed from the stable release.
#### Holding Packages
Sometimes, you might want to prevent a package from being upgraded.
**Debian-based:**
```bash
sudo apt-mark hold package-name
```
**Red Hat-based:**
Red Hat-based systems do not have a direct equivalent of holding packages, but you can exclude packages from being updated in the `dnf` configuration.
#### Using GUI Package Managers
For users who prefer a graphical interface, both Debian-based and Red Hat-based systems offer GUI tools.
**Debian-based:**
- **Synaptic Package Manager:** A powerful and easy-to-use package management tool.
```bash
sudo apt install synaptic
```
**Red Hat-based:**
- **GNOME Software:** A software center for browsing and installing applications.
```bash
sudo dnf install gnome-software
```
### Conclusion
Package management is an essential skill for anyone using or administering a Linux system. Whether you're on a Debian-based system like Ubuntu or a Red Hat-based system like CentOS, understanding how to update, install, upgrade, and remove packages will keep your system running smoothly. Advanced techniques like cleaning up, managing repositories, pinning, and holding packages, as well as using GUI tools, further enhance your ability to maintain a robust and efficient Linux environment.
By mastering these package management commands and concepts, you can ensure your Linux system remains up-to-date, secure, and optimized for your needs. Happy package managing! | iaadidev |

1,878,311 | “X” Mengizinkan Konten Pornografi: Melanggar Etika Komunikasi dan Terancam Diblokir Kominfo? | Dalam era digital saat ini, akses terhadap berbagai macam konten semakin mudah diperoleh melalui... | 0 | 2024-06-05T16:25:03 | https://dev.to/kameralda_naurahaqiilah/x-mengizinkan-konten-pornografi-melanggar-etika-komunikasi-dan-terancam-diblokir-kominfo-5a7a | twitter, kominfo |
Dalam era digital saat ini, akses terhadap berbagai macam konten semakin mudah diperoleh melalui berbagai platform media sosial. Namun, kemudahan ini tidak selalu diiringi dengan tanggung jawab dan kesadaran etika, terutama dalam konteks penyebaran konten pornografi. Baru-baru ini, platform “X” menghadapi ancaman diblokir oleh Kominfo karena dugaan pelanggaran terkait konten pornografi. Pertanyaannya, apakah tindakan “X” ini melanggar etika komunikasi dan bagaimana implikasinya terhadap kebebasan berekspresi serta tanggung jawab platform digital?
Etika komunikasi merujuk pada prinsip-prinsip moral yang mengatur bagaimana informasi disebarluaskan dan diterima dalam masyarakat. Prinsip ini mencakup kejujuran, tanggung jawab, privasi, dan penghormatan terhadap martabat manusia. Dalam konteks digital, platform media sosial memiliki tanggung jawab besar dalam memastikan konten yang dipublikasikan oleh pengguna sesuai dengan standar etika ini. Mengizinkan konten pornografi, yang secara jelas melanggar hukum dan norma sosial di banyak negara, termasuk Indonesia, menunjukkan ketidakpatuhan terhadap etika komunikasi. Konten semacam ini tidak hanya merusak moral publik tetapi juga dapat memicu berbagai masalah sosial, termasuk eksploitasi seksual dan penyalahgunaan data pribadi.
Muncul mengenai Ancaman Pemblokiran oleh Kominfo. Kominfo sebagai otoritas regulasi di Indonesia, memiliki mandat untuk mengawasi dan menegakkan peraturan terkait konten internet. Langkah mereka untuk memblokir platform yang mengizinkan konten pornografi bukan hanya soal penegakan hukum, tetapi juga upaya untuk melindungi masyarakat dari dampak negatif konten tersebut. Pemblokiran ini dapat dilihat sebagai langkah preventif untuk menjaga kesehatan mental dan moral publik, terutama di kalangan anak muda yang sangat rentan terhadap dampak negatif dari konten pornografi. Namun, ada juga kekhawatiran bahwa tindakan ini dapat berdampak pada kebebasan berekspresi dan penggunaan internet secara umum. Kebebasan berekspresi adalah hak asasi yang dijamin oleh berbagai instrumen hukum internasional dan nasional. Namun, hak ini tidak bersifat absolut dan harus dijalankan dengan penuh tanggung jawab.
Menteri Komunikasi dan Informatika Mengeluarkan Peringatan Keras kepada (“X”) atas Konten Pornografi
Dalam perkembangan terbaru, Menkominfo telah mengeluarkan peringatan keras kepada platform media sosial X. Peringatan ini terkait dengan kebijakan platform tersebut yang memperbolehkan pengguna untuk memposting konten pornografi. Menkominfo menekankan bahwa tindakan ini melanggar hukum dan norma sosial di Indonesia serta dapat membawa konsekuensi serius, termasuk potensi pemblokiran platform tersebut di tanah air. Platform digital memiliki peran penting dalam mengatur dan memoderasi konten yang dipublikasikan oleh penggunanya. Mengizinkan konten pornografi tidak hanya menimbulkan masalah etika, tetapi juga melanggar peraturan perundang-undangan yang berlaku. Di Indonesia, penyebaran konten pornografi merupakan pelanggaran hukum yang dapat dikenai sanksi berat. Peringatan dari Menkominfo mencerminkan keprihatinan pemerintah terhadap dampak negatif dari konten tersebut, terutama bagi generasi muda. Platform digital harus menyeimbangkan antara menyediakan ruang untuk kebebasan berekspresi dan memastikan bahwa konten yang tersedia tidak melanggar hukum atau norma sosial yang berlaku.
Dasar hukum yang melarang penyebaran konten ini tercantum dalam Undang-Undang Informasi dan Transaksi Elektronik (UU ITE), khususnya Pasal 27 ayat (1) dari UU 1/2024 tentang perubahan kedua UU ITE. Pasal ini melarang penyebaran informasi elektronik yang melanggar kesusilaan. Menkominfo menekankan bahwa kebijakan X yang mengizinkan konten dewasa tidak dapat diterapkan di Indonesia. Budi Arie Setiadi menegaskan bahwa semua kebijakan X yang bertentangan dengan aturan yang berlaku akan dikenai sanksi, termasuk pemblokiran dan/atau denda. Dibawah kepemimpinan Elon Musk, telah menambahkan klausul yang mengizinkan pengguna untuk memposting konten dewasa dan pornografi di platform, asalkan konten tersebut diberi label yang jelas dan diproduksi secara konsensual. Aturan baru ini juga mencakup video dan gambar yang dibuat oleh AI.
Dalam kasus “X”, mengizinkan konten pornografi menunjukkan kegagalan dalam menyeimbangkan dua hal tersebut. Platform ini tidak hanya gagal melindungi penggunanya dari konten yang merugikan, tetapi juga berisiko melanggar hukum dan regulasi setempat. Implikasi dari tindakan “X” dan ancaman pemblokiran oleh Kominfo bisa sangat luas. Pemblokiran ini dapat mempengaruhi pengguna yang sah dan mempengaruhi bisnis serta komunikasi yang sah yang bergantung pada platform tersebut.
Solusi terbaik adalah dengan meningkatkan upaya moderasi konten secara lebih ketat dan transparan. Platform harus memastikan konten yang tersedia memenuhi norma etika dan peraturan hukum yang ada. Selain itu, edukasi kepada pengguna tentang bahaya dan konsekuensi dari menyebarkan atau mengonsumsi konten pornografi juga sangat penting. Mengizinkan konten pornografi di platform digital seperti “X” jelas melanggar etika komunikasi dan membawa berbagai risiko sosial dan hukum. Ancaman pemblokiran oleh Kominfo merupakan respons yang wajar dalam upaya melindungi masyarakat dari dampak negatif konten tersebut. Namun, penting untuk diingat bahwa solusi jangka panjang harus mencakup peningkatan moderasi konten dan edukasi pengguna agar internet tetap menjadi ruang yang aman dan bermanfaat bagi semua.

theme-type: light,
primary: mat.$azure-palette,
tertiary: mat.$blue-palette,
),
density: (
scale: 0,
),
)
);
```
We are going to make changes in above code to achieve customizations through CSS custom properties.
#### Add `use-system-variables: true`
Make changes in `color` and `typography` maps as below:
```scss
$my-material-app-theme: mat.define-theme(
(
color: (
theme-type: light,
primary: mat.$azure-palette,
tertiary: mat.$blue-palette,
use-system-variables: true, // 👈 Added
),
typography: (
use-system-variables: true, // 👈 Added
),
density: (
scale: 0,
),
)
);
```
### Modifying `:root` selector
Next, add below mixins in `:root`:
```scss
:root {
@include mat.all-component-themes($my-material-app-theme);
@include mat.system-level-colors($my-material-app-theme); // 👈 Added
@include mat.system-level-typography($my-material-app-theme); // 👈 Added
}
```
## Generating theme from Theme Builder
Now go to [themes.angular-material.dev](https://themes.angular-material.dev), modify colors as per your need and copy the CSS variables.

### Using CSS variables
Now, create a new file at `src/styles/root.css` and paste all content in it. Simply import that file through `angular.json`'s `styles` property! Or any other dynamic way, such that `root.css` file is rendered in correct order to reflect all `--sys-*` variables.
```json
{
"styles": [
"src/styles.scss",
"src/styles/root.css"
],
}

Despite its critical role in... | 0 | 2024-06-05T16:11:00 | https://dev.to/ivangavlik/how-to-improve-the-pull-request-process-59c5 | pullrequest, programming, productivity, github | The pull request (PR) process is essential but often disliked. Despite its critical role in maintaining code quality, many developers find it frustrating. Let's explore common issues and solutions to make PRs more effective and enjoyable.
## Common Issues with the PR Process
**1. Focusing on the Developer Rather Than the Code**
Reviewers often direct comments at the developer instead of the code. Using second-person pronouns like "you" or "your" can make comments seem personal and toxic. Instead, focus on technical aspects and the code itself.
**Solution:**
- Concentrate on the code, not the person.
- Avoid personal pronouns; use objective language.
**2. Skimming Through Reviews**
Large PRs often lead to superficial reviews. It's easy to overlook issues in big chunks of code.
**Solution:**
- Break down large PRs into manageable pieces.
- Allocate focused time (25-45 minutes) for thorough reviews.
- Encourage collaborative code ownership.
**3. Writing Ineffective Comments**
Comments can be subjective, unclear, and lack actionable outcomes.
**Solution:**
- Be objective: Explain why changes are needed with clear, factual reasoning.
- Be specific: Point out exact lines or methods.
- Focus on outcomes: Use the Triple R pattern (Request, Rationale, Result).
- Labels for Comments:
needChange: Minor changes.
needRework: Major changes requiring discussion.
nitpicks: Subjective comments that don't affect functionality.
TODO: Conventional comments for future work.
Example:
> Can we move this method to Class AX? Similar methods are in Class AX, consolidating them will streamline business logic processing.
**4. Not Being Your Own First Reviewer**
Authors should review their code before submitting it.
**Solution:**
- Use draft PRs to self-review and refine code.
**5. Not Using Automation**
Automation can catch lower-stakes issues before the review.
**Solution:**
- Implement linting, formatting tools, and static analysis.
- Ensure tests pass before submitting PRs.
**6. Unmanageable PRs**
Large, unfocused PRs are difficult to review.
Solution:
- Make PRs narrow and specific.
- Focus on atomic changes.
- Split large features into multiple smaller PRs.
**7. Treating PRs as Mystery Novels**
PRs should be clear and informative.
**Solution:**
- Provide context and a clear title.
- Explain the purpose and changes in the PR description.
**8. Taking Feedback Personally**
Feedback is an opportunity to improve, not a critique of your abilities.
**Solution:**
- Embrace feedback as a team effort to enhance code quality.
## Additional Tips
- Create a Team Working Agreement: Define coding conventions and processes, and establish a "definition of done."
- Use PR Templates: Standardize PR descriptions for clarity.
- Auto-Assign Reviewers: Ensure timely reviews.
- Celebrate Code Complements: Recognize good work.
By addressing these issues and implementing these solutions, we can improve the PR process, making it more efficient and less stressful for everyone involved.

1,878,246 | Take Your First Steps for Building on LLMs with Google Gemini | It seems like there are endless possibilities for innovation with LLMs. If you’re like me, you’ve... | 0 | 2024-06-05T15:56:53 | https://dzone.com/articles/take-your-first-steps-for-building-on-llms | webdev, tutorial, javascript, ai | It seems like there are endless possibilities for innovation with LLMs. If you’re like me, you’ve used GenAI applications and tools — like ChatGPT built into Expedia, or Copilot for code writing, or even DALL-E for generating images. But as a technologist, I want to do more than just use LLM-based tools. I want to build my own.
(I told DALL-E to “*Generate a watercolor of a computer programmer thinking about all the things he could build with LLMs.*” Yeah, this is pretty spot on.)
With all new technologies, becoming a builder means starting simple. It’s like this for any new programming language I’m learning or any new framework I’m checking out. Building with LLMs is no different. So, that’s what I’m going to walk through here. I’m going to build a quick and dirty API that interacts with Google Gemini, effectively giving me a little chatbot assistant of my own.
Here’s what we’ll do:
1. Briefly introduce Google Gemini.
2. Build the simple Node.js application.
3. Deploy the application to Heroku.
4. Test it.
## What is Google Gemini?
Most everyday consumers know about ChatGPT, which is built on the GPT-4 LLM. But when it comes to LLMs, GPT-4 isn’t the only game in town. There’s also [Google Gemini](https://blog.google/technology/ai/google-gemini-ai) (which was formerly known as Bard). Across most performance benchmarks (such as multi-discipline college-level reasoning problems or Python code generation), Gemini outperforms GPT-4.
What does Gemini say about itself?
As developers, we can access Gemini via the Gemini API in [Google AI Studio](https://ai.google.dev/). There are also SDKs available for [Python](https://github.com/google-gemini/generative-ai-python), [JavaScript](https://github.com/google-gemini/generative-ai-js), [Swift](https://github.com/google-gemini/generative-ai-swift), and [Android](https://github.com/google-gemini/generative-ai-android).
Alright. Let’s get to building.
### Build the Node.js application
Our Node.js application will be a simple [Express](https://expressjs.com/) API server that functions like a Gemini chatbot. It will listen on two endpoints. First, a `POST` request to `/chat` (which will include a JSON payload with a `message` attribute) will send the message to Gemini and then return the response. Our application will keep a running chat conversation with Gemini. This turns our chatbot into a helpful assistant who can hold onto notes for us.
Second, if we send a `POST` request to `/reset`, this will reset the chat conversation to start from scratch, effectively erasing Gemini’s memory of previous interactions with us.
If you want to skip this code walkthrough, you can see all the code at my [GitHub repo here](https://github.com/alvinslee/heroku-gemini-node).
### Initialize the application
To get started, we initialize our Node.js application and install dependencies.
```bash
~/project$ npm init -y && npm pkg set type="module"
~/project$ npm install @google/generative-ai dotenv express
```
Then, we add this to the `scripts` in our `package.json` file:
```json
"scripts": {
"start": "node index.js"
},
```
### The `index.js` file
Our application consists of one file, and it’s pretty simple. We’ll walk through it a section at a time.
First, we import all the packages we’ll be using. Then, we initialize the SDK from Google AI. We’ll use the gemini-pro model. Lastly, we call [`startChat`](https://github.com/google-gemini/generative-ai-js/blob/main/docs/reference/main/generative-ai.generativemodel.startchat.md), which creates a new [`ChatSession`](https://github.com/google-gemini/generative-ai-js/blob/main/docs/reference/main/generative-ai.chatsession.md) instance for what Google calls a [multi-turn conversation](https://ai.google.dev/gemini-api/docs/get-started/node#multi-turn-conversations-chat).
```javascript
import 'dotenv/config';
import express from 'express';
import { GoogleGenerativeAI } from '@google/generative-ai';
const genAI = new GoogleGenerativeAI(process.env.GEMINI_API_KEY);
const model = genAI.getGenerativeModel({ model: "gemini-pro"});
let chat = model.startChat();
```
Next, we instantiate a new Express app, which is our API server.
```javascript
const app = express();
app.use(express.json())
```
Then, we set up our listener for `POST` requests to the `/chat` endpoint. We make sure that the JSON payload body includes a `message`. We use our `chat` object to send that message to Gemini. Then, we respond to our API caller with the response text from Gemini.
```javascript
app.post('/chat', async (req, res) => {
if ((typeof req.body.message) === 'undefined' ||
!req.body.message.length) {
res.status(400).send('"message" missing in request body');
return;
}
const result = await chat.sendMessage(req.body.message);
const response = await result.response;
res.status(200).send(response.text());
})
```
Keep in mind that, by using a `ChatSession`, there’s a stored, running history of our interaction with Gemini across all API calls. Giving Gemini a “memory” of our conversation is helpful for context.
But what if you want Gemini to start over completely and forget all previous context? For this we have the `/reset` endpoint. This simply starts up a new `ChatSession`.
```javascript
app.post('/reset', async (req, res) => {
chat = model.startChat();
res.status(200).send('OK');
})
```
Finally, we start up our server to begin listening.
```javascript
const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
console.log(`Server is running on port ${PORT}`)
})
```
As a side note, this entire project is just a mini demo. It’s not meant to be used in production! The way I’ve designed it for now (without authentication), anybody with the URL can send a request to `/chat` to `/reset`. In a production setup, we would have proper authentication in place, and each user would have their own instance of a conversation with Gemini which nobody else could manipulate.
### Obtaining a Gemini API key
At this point, we’re almost ready to go. The last thing we need is an API key to access the Gemini API. To get an API key, start by signing up for a [Google AI for Developers account](https://ai.google.dev/gemini-api/docs).
Once you’re logged in, select **Launch Google AI Studio** to start a new Google Gemini project.
Within the project, click **Get API key** to navigate to the API keys page. Then, click **Create API key** to generate a key. Copy the value.
In your project, copy the file called `.env.template` as a new file called `.env`. Paste in the value of your Gemini API key. Your `.env` file should look similar to this:
```bash
GEMINI_API_KEY=ABCDEFGH0123456789_JJJ
```
### Test our application locally
With everything in place, we can spin up our server locally to test it.
```bash
~/project$ npm start
> heroku-gemini-node@1.0.0 start
> node index.js
Server is running on port 3000
```
In a different terminal, we can send some curl requests:
```bash
$ curl -X POST -H 'content-type:application/json' \
--data '{"message":"I would like to bake a shepherds pie to feed 8 \
people. As you come up with a recipe, please keep a grocery \
list for me with all of the ingredients that I would need to \
purchase."}' \
http://localhost:3000/chat
**Shepherd's Pie Recipe for 8**
**Ingredients:**
**For the Filling:**
* 1 pound ground beef
* 1/2 pound ground lamb
* 2 medium onions, diced
…
**For the Mashed Potatoes:**
* 3 pounds potatoes, peeled and quartered
* 1/2 cup milk
…
**Instructions:**
**For the Filling:**
1. Heat a large skillet over medium heat. Add the ground beef and lamb
and cook until browned.
…
$ curl -X POST -H 'content-type:application/json' \
--data '{"message":"I also need to buy fresh basil, for a different
dish (not the shepherds pie). Add that to my grocery list \
too."}' \
http://localhost:3000/chat
**Updated Grocery List for Shepherd's Pie for 8, and Fresh Basil:**
* 1 pound ground beef
* 1/2 pound ground lamb
* 2 medium onions
* 2 carrots
* 2 celery stalks
* 1 bag frozen peas
* 1 bag frozen corn
* 1 tablespoon Worcestershire sauce
* 1 teaspoon dried thyme
* 1 cup beef broth
* 1/4 cup tomato paste
* 3 pounds potatoes
* 1/2 cup milk
* 1/4 cup butter
* **Fresh basil**
$ curl -X POST -H 'content-type:application/json' \
--data '{"message":"What items on my grocery list can I find in the \
produce section?"}' \
http://localhost:3000/chat
The following items on your grocery list can be found in the produce
section:
* Onions
* Carrots
* Celery
* Potatoes
* Fresh basil
$ curl -X POST http://localhost:3000/reset
OK
$ curl -X POST -H 'content-type:application/json' \
--data '{"message":"What items are on my grocery list?"}' \
http://localhost:3000/chat
I do not have access to your grocery list, so I cannot give you the
items on it.
```
It’s working. Looks like we’re ready to deploy!
## Deploy our application to Heroku
To deploy our application, I’ve opted to go with Heroku. It’s quick, simple, and low-cost. I can get my code running in the cloud with just a few simple steps, without getting bogged down in all of the nitty-gritty infrastructure concerns. This way, I can just focus on building cool applications.
After signing up for a Heroku account and [installing the CLI](https://devcenter.heroku.com/articles/heroku-cli), here’s what it takes to deploy.
### Add `Procfile` to the codebase
We need to include a file called `Procfile` which tells Heroku how to start up our application. The contents of `Procfile` look like this:
```bash
web: npm start
```
We commit this file to our codebase repo.
### Log in to Heroku (via the CLI)
```bash
~/project$ heroku login
```
### Create app
```bash
~/project$ heroku create gemini-chatbot
Creating ⬢ gemini-chatbot... done
https://gemini-chatbot-1933c7b1f717.herokuapp.com/ | https://git.heroku.com/gemini-chatbot.git
```
### Add Gemini API key as config environment variable
```bash
~/project$ heroku config:add \
--app gemini-chatbot \
GEMINI_API_KEY=ABCDEFGH0123456789_JJJ
Setting GEMINI_API_KEY and restarting ⬢ gemini-chatbot... done, v3
GEMINI_API_KEY: ABCDEFGH0123456789_JJJ
```
### Push code to Heroku remote
```bash
~/project$ git push heroku main
...
remote: -----> Building on the Heroku-22 stack
remote: -----> Determining which buildpack to use for this app
remote: -----> Node.js app detected
...
remote: -----> Build succeeded!
remote: -----> Discovering process types
remote: Procfile declares types -> web
remote:
remote: -----> Compressing...
remote: Done: 45.4M
remote: -----> Launching...
remote: Released v4
remote: https://gemini-chatbot-1933c7b1f717.herokuapp.com/ deployed to Heroku
```
That’s it? That’s it.
### Test our deployed application
With our application deployed, let’s send some curl requests to our Heroku app URL.
```bash
$ curl -X POST -H 'content-type:application/json' \
--data '{"message":"If I ask you later for my PIN, remind me that it \
is 12345."}' \
https://gemini-chatbot-1933c7b1f717.herokuapp.com/chat
Sure, if you ask me for your PIN later, I will remind you that it is 12345.
**Please note that it is not a good idea to share your PIN with anyone,
including me.** Your PIN is a secret code that should only be known to you.
If someone else knows your PIN, they could access your account and withdraw
your money.
$ curl -X POST -H 'content-type:application/json' \
--data '{"message":"What is my PIN?"}' \
https://gemini-chatbot-1933c7b1f717.herokuapp.com/chat
Your PIN is 12345.
$ curl -X POST https://gemini-chatbot-1933c7b1f717.herokuapp.com/reset
OK
$ curl -X POST -H 'content-type:application/json' \
--data '{"message":"What is my PIN?"}' \
https://gemini-chatbot-1933c7b1f717.herokuapp.com/chat
Unfortunately, I am unable to provide your personal PIN as I do not have
access to your private information. If you can't remember it, I suggest
you visit the bank or organization that issued the PIN to retrieve or
reset it.
```
## Conclusion
Now is a great time to build LLM-based applications. Ride the wave!
We’ve walked through how to build a simple LLM-based application on top of Google Gemini. Our simple chatbot assistant is basic, but it’s a great way to familiarize yourself with the Gemini API and its associated SDKs. And by using Heroku for deployment, you can offload the secondary concerns so that you can focus on learning and building where it counts. | alvinslee |

---
If you plan to start a restaurant business in online, the first initiative must focus on streamlining the ordering and delivering process. Popularly known as food delivery system, this application will provide reliable 24/7 connectivity for everyone involved in the loop. The main players in food delivery business are your business, restaurants, deliverers, customers, and payment gateway providers.
In today's competitive restaurant business, the key to success lies in embracing technological advancements and software. It has emerged as a game-changer for establishments seeking to thrive in the digital age. Powerful software solutions empower restaurant owners with the tools and capabilities needed to efficiently manage multiple aspects of their operations, from order processing and menu management to inventory control and delivery logistics.
## What to Expect in Restaurant Business Software?
With so many restaurant system providers, anyone can easily get confused and choose the wrong system. The purpose of this blog is to give prospective multi-restaurant vendors as well as established restaurant businesses a clear view of what they should have in the system that they propose to buy.
Here are some important points to consider before placing an order for an ordering system.
### Differences between White Label and SaaS Systems
The white label allows you a high degree of flexibility and you also own the software. You will have access to the code and you can choose to make changes or update it as you want. Your business can choose its own name as well. The software vendors of White Label products offer a fixed price.
The SaaS system uses monthly or annual billing as per the plan you opt for. To use the SaaS system, you must renew it as per the plan offers. You cannot make changes to the software or ask for additional feature upgrades.
### Branding Compatibility
The [multi restaurant online ordering system](https://www.kopatech.com/multi-restaurant-delivery-software) must be compatible to use your own brand name. This is an advantage. Your customers and restaurants will instantly recollect your business. It will help you build your reputation and brand image. A consistent and cohesive branding strategy creates a sense of familiarity and trust among customers, making them more likely to engage with the restaurant's online ordering platform.
The ordering system should seamlessly integrate the restaurant's logo, color scheme, and visual elements to mirror the brand identity across all touchpoints. When customers visit the online platform, they should immediately recognize the restaurant and feel a connection to the brand they already know and love. This alignment enhances brand recall and reinforces the restaurant's image, ultimately leading to increased customer loyalty and repeat business.
### Custom Built for Food Delivery
The [food ordering System](https://www.kopatech.com/online-food-ordering-system) that you consider for your restaurant business must have been made especially for food delivery. A more generic delivery app will not have every desirable feature. It might require reconfiguring and some coding. This means more expenses and higher time for implementing it in your business.
### Online and Offline Payment Compatibility
To make life easy for your customers and widen the user base, you need to give them both online and offline simple and easy payment methods. The online payment will be integrated with the customer module and payment can be initiated in the module itself. The offline payment methods should include Internet banking, debit, and credit card payments. Offline payment methods will allow customers to make payments outside the app and cash on delivery (COD). With the wallet feature, you can help customers to make quick payments in simple steps.
### Driver, Restaurant Rating and Review System
Any app designed for a restaurant business must have a review rating feature. It will allow the delivery administrator to get feedback about customer experience and drivers' quality of service. Reviews can be used for improving the delivery process and removing erring drivers.
These play a crucial role in ensuring a seamless and satisfactory customer experience throughout the entire ordering and delivery process. The availability of reliable delivery drivers is essential for timely and efficient order deliveries. A well-integrated Driver System allows restaurants to assign delivery partners based on proximity and availability, minimizing delivery times and enhancing overall customer satisfaction. Additionally, the system can provide real-time tracking of delivery status, enabling customers to monitor their orders and stay informed, further boosting their confidence in the restaurant's service.
Customer reviews and ratings serve as valuable feedback for both the restaurants and potential customers. Positive reviews and high ratings can attract new customers, while constructive criticism in reviews can help restaurants identify areas for improvement and refine their offerings to meet customer expectations better.
By incorporating a well-designed system, the restaurant business can actively engage with its customers, respond to feedback, and build a loyal customer base. Ultimately, a transparent and effective rating and review system instills confidence in customers, encouraging them to place orders and creating a positive reputation for the restaurant, which is crucial for success in today's competitive market.
### Instant Notification, SMS, and Emails
Instant notification, SMS, and emails are crucial features to consider when choosing an ordering system for a restaurant business due to their pivotal role in ensuring timely and effective communication with customers, staff, and delivery partners. Instant notifications are essential for real-time updates on order status, enabling customers to stay informed about their orders from the moment they are placed until delivery or pickup. This feature enhances transparency and customer satisfaction, as it minimizes uncertainty and keeps customers engaged throughout the ordering process. It allows restaurants to promptly notify customers about promotions, discounts, and special offers, increasing the likelihood of repeat business and building a loyal customer base.
Secondly, SMS and emails play a vital role in enhancing communication efficiency within the restaurant's operations. When integrated into other systems, SMS and emails allow the restaurant to efficiently confirm orders, send order updates, and provide delivery notifications to customers. This seamless communication process reduces the chances of order errors and enhances the overall customer experience.
### Restaurant Order Management App
The restaurant order management app is a vital functionality that must be a part of the App. This is the place where the restaurant will accept orders, showcase the menu, and take down special requests from customers. This feature will be convenient to show restaurant opening and closing times and the average time it will require for preparing and dispatching the ordered food.
### Delivery Zone Modules
The ordering system must have different modules for each employee performing a different role in the delivery loop. There should be one for the restaurant manager with full control, one for the deliverer, and one for the customer. Each will have its own features and levels of control.
### Advanced Cart and Checkout for Customers
There are many advanced features in the cart and checkout module that can be incorporated – examples are: advance food booking and delivery requests at predetermined locations, redeeming discount coupons, updating order instructions, splitting expenses at the time of checkout, and ordering for weeks or daily basis.
## The Importance of User-friendliness in Ordering Systems
Friendly Menu Management and Menu Setup are critical factors to consider when choosing an ordering system for a restaurant business. Firstly, a user-friendly menu management interface allows restaurant owners and staff to efficiently update, modify, and customize their menus without the need for extensive technical knowledge or support. The ability to easily add or remove items, update prices, and create special promotions empowers restaurants to respond swiftly to changes in ingredients, seasonal offerings, or market demands.
A well-designed menu management system ensures that customers can quickly navigate the menu, browse through available items, and make selections seamlessly. A clear and intuitive menu setup enhances the overall user experience, reducing the chances of customer frustration and order errors, and ultimately contributing to higher customer satisfaction and repeat business.
An effective menu setup is crucial for presenting a cohesive and appealing brand image to customers. The multi-restaurant ordering system should allow restaurants to showcase their unique offerings, branding elements, and special features in a visually appealing and organized manner. This includes the ability to add high-quality images, detailed descriptions, and dietary information to entice and inform customers.
A system that supports easy categorization and sorting of menu items enables restaurants to present their menus in a logical and user-friendly manner, helping customers find what they want quickly and contributing to a positive overall impression of the restaurant's online ordering platform.
### Making the Final Choice Intelligently
Choosing the best software for a multi-restaurant business is vital for staying competitive in today's food delivery industry. Embracing technological advancements and the most appropriate solution can significantly impact operations, and foster brand loyalty. A user-friendly interface not only simplifies menu updates for restaurant staff but also ensures a seamless and delightful ordering experience for customers, ultimately leading to higher satisfaction levels and increased customer loyalty. By carefully considering these factors and choosing the right software, restaurant owners can position themselves for success in the competitive landscape of the digital age.

Each of the risks refers to one or more Common Weakness Enumeration (CWE) categories, such as Cross-Site Request Forgery or Improper Input Validation. It has been used as a de-facto standard for web application security verification since its inception, although the project encourages the adoption of formal standards, such as the [OWASP Application Security Verification Standard (ASVS)](https://asvs.owasp.org) and [Security Assurance Maturity Model (SAMM)](https://owaspsamm.org/).
Since its first release in January 2003, the OWASP Top 10 has influenced cybersecurity best practice. It has raised awareness around weaknesses such as SQL Injection and Cross-Site Scripting, which used to plague most web applications. The most famous early edition was the OWASP Top 10 2004. Every three or four years, a new version has been released. Since 2007, the OWASP Top 10 has been based upon data obtained from multiple sources, with one or two subjective additions that deal with contemporary application security issues.
Now it’s time for the OWASP Top 10 2024, and you can be a part of it!
# Current Status of 2024 Edition
The OWASP Top 10 relies on data. Its widespread adoption is the result of our rigorous data collection, normalization, and analysis, which emphasizes real world risks over esoteric and difficult to exploit weaknesses.
In 2021, we obtained data from many different sources, including boutique consultancies, large multinational security consultancies, bug bounty programs, and automated tools (both human assisted and completely automated). The wide variety of data sources and methodologies – over 550,000 applications’ worth – behind the OWASP Top 10 have made it one of the world’s largest application security data sets.
Cross-Site Request Forgery (CSRF) was inserted by the authors in 2007 without a lot of backing data, since it affected nearly all applications. This made its inclusion slightly controversial. In the same vein, since 2017, we’ve run month-long industry surveys on OWASP’s social media channels to identify one or two subjective risks for each new release of the OWASP Top 10. As we are limited to just ten risks, we can’t include every single weakness, so running an industry survey helps build confidence that the injected risks are real and worthy of inclusion. In 2024, we are expecting the technical controls required by the EU Cyber Resilience Act (CRA) to feature heavily in the survey, but we will only know once the survey has been completed.
## When will OWASP Top 10 2024 be released?
We are planning on releasing the OWASP Top 10 2024 at the OWASP Global AppSec San Francisco in late September 2024, although we may need to push the release back if we have insufficient data. We don’t yet have anywhere near the mass of data necessary for the new edition. We have optimized the weighting of various data methodologies, allowing us to achieve the same level of confidence with less data, but we are still far from comfortable with the current sample size.
There are six phases to the writing and release process we adopted in 2017: data collection, data normalization and analysis, writing, industry survey, review process including a public comment period of early exposure drafts, and finally translations. The whole process is documented on the OWASP Top 10 website (https://owasptopten.org/).
Currently, we are stuck in data collection. We need to move forward with the other phases, otherwise the OWASP Top 10 2024 will be very late indeed.
# Contributing Data
You can get involved by submitting your data to the OWASP Top 10 project. We accept data from source code reviews, penetration tests, bug bounty programs, triaged tool output, and more. To normalize contribution format, we provide CSV and JSON templates (https://github.com/OWASP/Top10/tree/master/2024/Data). Your data is anonymized and mixed, so to prevent attribution to any one vendor, consultancy, or security researcher.
There are two types of datasets, which we recommend submitting separately. Humans Assisted By Tools (HaT) datasets are created by humans using tools to obtain or document the results. These are varied, with a low false positive rate, but with potentially esoteric results. Tools Assisted By Humans (TaH) datasets are output by tools doing the work, but triaged by humans. These frequently include the same 15-20 CWEs time and again, but with a higher false positive rate.
Human involvement is important. We generally do not accept untriaged tool output; if you have it, please let us know and we will see if it matches with our overall combined data sets. If there’s insufficient confidence that the output matches our other data, we won’t include it.
The following data elements are *required or optional:
Per DataSet:
* Contributor name (organization), or anonymous
* Contributor contact email
* Time period (2024, 2023, 2022, 2021)
* Number of applications tested (required)
* CWEs, with the number of applications in which each was found (required)
* Type of testing: TaH, HaT, or untriaged tool output
* Primary programming language
* Geographic region (global, North America, EU, Asia, other)
* Primary industry (multiple, financial, industrial, software)
* Whether or not data contains retests or the same applications multiple times (true/false)
If you can assist with data collection, please head on over to the OWASP Top 10 team website, and follow the instructions: https://owasptopten.org/owasp-top-ten-data-collection-is-open
We look forward to seeing your data in the OWASP Top 10. The more data we can get, the more accurate and useful the OWASP Top 10 is going to be!

To ensure that only authorized users can access specific features and data within an application, implementing Role-Based Access Control (RBAC) is essential.
In this article, I will show you how to implement RBAC into a Node.js and Express application using Permify.

<h2 id="setting-up-expressjs-project">Setting Up Node.js Express Project</h2>
To quickly create an application skeleton for your Express.js project, you can use the `express-generator` tool.
Follow these steps to get started:
### Step 1. Install express-generator:
If you're using Node.js version 8.2.0 or later, you can run the application generator using the npx command:
```bash
npx express-generator
```
For earlier Node versions, you can install the application generator as a global npm package:
```bash
npm install -g express-generator
```
### Step 2. Generate Your Express Application:
Once you have `express-generator` installed, you can create your Express application. Display the command options with the `-h` option:
```bash
express -h
```
This will show you the available options for generating your Express application.
For example, to create an Express app named `permify-rbac-app` with the Pug view engine, you can run:
```bash
express --view=pug permify-rbac-app
```
This command will create a folder named `permify-rbac-app` in the current working directory, along with the necessary files and folders for your Express application.
### Step 3. Install Dependencies:
Navigate into your newly created Express application directory:
```bash
cd permify-rbac-app
```
Then, install the project dependencies using `npm`:
```bash
npm install express && npm install @permify-node
```
### Step 4. Start Your Express Application:
On MacOS or Linux, you can start the app with the following command:
```bash
DEBUG=permify-rbac-app:* npm start
```
### Step 5. Access Your Application:
Once your Express application is running, you can access it in your browser at `http://localhost:3000/`.
### Directory Structure:
The generated Express application will have the following directory structure:
```bash
permify-rbac-app/
├── app.js
├── bin/
│ └── www
├── package.json
├── public/
│ ├── images/
│ ├── javascripts/
│ └── stylesheets/
│ └── style.css
├── routes/
│ ├── index.js
│ └── users.js
└── views/
├── error.pug
├── index.pug
└── layout.pug
```
This structure includes the main application file (app.js), the server configuration (bin/www), routes, views, public assets, and the package.json file with project dependencies.
Now that you have set up our Express.js project, we'll proceed to implement RBAC to our Express application.
<h2 id="implementing-rbac-in-nodejs-and-express">Implementing RBAC in Node.js and Express</h2>
Implementing Role-Based Access Control (RBAC) in a Node.js and Express application involves several steps. Here's a basic implementation:
<h3 id="designing-the-rbac-model-with-permify">Step 1: Designing the RBAC Model with Permify</h3>
[Permify](https://github.com/Permify/permify) is an open source authorization service that allows developers to create authorization systems. With Permify you can model your authorization, create central authorization service in your environment and perform access checks from your applications and services.
It does this by providing client SDKs, which you can add into your middleware to send authorization requests, such as access check.
Permify offers a powerful domain-specific language (DSL) to define roles, permissions, and relationships. You can utilize the [Permify Playground](https://play.permify.co/?s=rbac) to experiment and visualize your RBAC model.
For this post, we will develop a simple file-based authorization system where users within your organization can access documents based on their roles.
Different roles such as Admin, Manager, and Employee may have different levels of access to view, edit, or delete files.
#### Defining Roles and Permissions with Permify DSL
Below is an example Permify DSL schema for our RBAC model:
```javascript
entity user {}
entity organization {
// roles
relation admin @user
relation member @user
relation manager @user
relation agent @user
// organization files access permissions
permission view_files = admin or manager or (member not agent)
permission delete_file = admin
// vendor files access permissions
permission view_vendor_files = admin or manager or agent
permission delete_vendor_file = agent
}
```
**Roles and Permissions**:
- **Roles**: The schema defines roles for the organization entity, including `admin`, `member`, `manager`, and `agent`. These roles determine the level of access and permissions users have within the organization.
- **Permissions**: Actions such as `view_files`, `edit_files`, `delete_file`, `view_vendor_files`, `edit_vendor_files`, and `delete_vendor_file` define the specific permissions associated with each role. For example, only admins can delete organization files, while managers and members have different levels of access.
**Resource Types:**
- The schema distinguishes between organization files and vendor files, each with its own set of permissions. This allows for granular control over access to different types of resources within the application.
Now that we have our RBAC schema defined, we'll proceed to setting up an Permify Local Server.
<h3 id="setting-up-a-permify-local-server-with-docker">Step 2: Setting Up a Permify Local Server with Docker</h3>
Docker plays a crucial role in our setup by providing a containerized environment.
This environment is essential for the efficient operation of Permify, which functions as a microservice responsible for all authorization queries.
Now we will cover the steps needed to set up the Permify Server with using Docker Container below:
#### Run Permify Server with Docker Container
- Open a terminal window and run the following command to pull the Permify Server Docker image and start the container:
```sh
sudo docker run -p 3476:3476 -p 3478:3478 ghcr.io/permify/permify serve
```
This command will download the Permify Server image from the GitHub Container Registry and sets up Permify, our authorization service, with the following default settings:
- The REST API running on port 3476.
- The gRPC Service running on port 3478.
- Authorization data is stored in the computer's memory.
You should see a message similar to this:
```bash

```
#### Verify Permify Server
Once the container is running, you can verify that Permify Server is running correctly by accessing the health check endpoint. Open Postman and send a GET request to `http://localhost:3476/healthz`. If Permify Server is running correctly, you should see a response indicating that the service is healthy.
The above image shows that Permify Server is up and running, you can now proceed with integrating it into your Node.js and Express application.
<h3 id="initialize-permify-node-client">Step 3: Initialize Permify Node.js Client</h3>
In this tutorial, we'll use [Permify Node Client](https://github.com/Permify/permify-node) to control authorization in our application. You can find the list of available endpoints in our [Permify Swagger Docs](https://permify.github.io/permify-swagger/). We'll be using Permify's access control checks to safeguard our endpoints.
Let's initialize our our client,
```js
// create-tenant.js
const permify = require("@permify/permify-node");
const client = new permify.grpc.newClient({
endpoint: "localhost:3478",
})
```
<h3 id="configure-authorization-model">Step 4: Configure Authorization Model</h3>
Now as our Permify Server running, we need to configure our authorization model to Permify service and then we can ready to perform test access checks.
To configure the authorization model, we'll send the schema we created to Permify using the Permify [schema.write](https://docs.permify.co/api-reference/schema/write-schema) method.
```js
//create-schema.js
const permify = require("@permify/permify-node");
const client = new permify.grpc.newClient({
endpoint: "localhost:3478",
})
client.schema.write({
tenantId: "t1",
schema: "entity user {} \n\nentity organization {\n\n relation admin @user \n relation member @user \n relation manager @user \n relation agent @user \n\n action view_files = admin or manager or (member not agent)\n action edit_files = admin or manager\n action delete_file = admin\n action view_vendor_files = admin or manager or agent\n action edit_vendor_files = admin or agent\n action delete_vendor_file = agent\n\n} "
}).then((response) => {
// handle response
console.log(response)
})
```
This code above creates a new schema using the Permify library.
It is built to connect to the Permify server running on localhost port `3478` and then calls the write method to define a schema for the specified tenant `t1`.
The schema defines entities such as `user` and `organization` along with their relationships and actions.
Now, let's run this script
```sh
node create-schema.js
```
From the output in screenshot above, you can see that the new schema was successfully configured using Permify Node Js Client.
Hooray! 🥳 We've successfully finished setting up the Permify authorization service. Our API is now up and running with the authorization model configured and ready for use!
In the next step, we will be creating the middleware for access control.
<h3 id="create-access-control-middleware">Step 5: Creating Access Control Middleware </h3>
Here I will show an example of how we'll develop Express middleware to enforce role-based access control on routes.
You will also learn how to implement Permify access check endpoint in the middleware to verify a user's role and permissions before allowing access to protected resources.
```js
// auth.js
// Import Permify client
const permify = require('@permify/permify-node');
const client = new permify.grpc.newClient({
endpoint: "localhost:3478",
});
// Middleware function to check user's permissions
const checkPermissions = (permissionType) => {
return async (req, res, next) => {
try {
// Ensure req.params.id exists
if (!req.params.id) {
throw new Error('User ID is missing in the request parameters');
}
// Convert permissionType to string if necessary
const permTypeString = String(permissionType);
// Prepare data for Permify check request
const checkRes = await client.permission.check({
tenantId: 't1',
metadata: {
schemaVersion: '',
snapToken: '',
depth: 20,
},
entity: {
type: 'organization',
id: "1",
},
permission: permTypeString, // Use the converted permissionType
subject: {
type: 'user',
id: req.params.id,
},
});
if (checkRes.can === 1) {
// If user is authorized
req.authorized = 'authorized';
next();
} else {
// If user is not authorized
req.authorized = 'not authorized';
next();
}
} catch (err) {
console.error('Error checking permissions:', err.message); // Log the actual error message
res.status(500).send(err.message); // Send the actual error message to the client for debugging purposes
}
};
};
module.exports = checkPermissions;
```
The code above is built with the aim to implement a middleware function, [checkPermission](https://docs.permify.co/api-reference/permission/check-api) by utilizing the Permify library to verify user permissions based on the provided permission type.
When executed it extracts the user ID from the request parameters, converts the permission type to a string if needed, then sends a permission check request using Permify's `"permission.check"` method to the Permify server. If authorized, it adds `"authorized"` to the request object; otherwise, it adds `"not authorized"`.
Errors are further logged and returned to the client for debugging purposes.
Next, we'll integrate the middleware that was created above into our Node.js and Express application to enforce Role-Based Access Control (RBAC) and ensure that only authorized users with the appropriate roles and permissions can access specific routes.
<h3 id="securing-the-routes">Step 6: Securing Routes with RBAC</h3>
Now, let's secure our routes using the middleware we've created. We'll apply the `checkPermissions` middleware to protect various routes in our application.
```js
// app.js
// Import required modules
const express = require('express');
const permify = require("@permify/permify-node");
const authMiddleware = require('./auth'); // Import the auth middleware
// Create Express app
const app = express();
// Define custom middleware to populate userInfo
app.use((req, res, next) => {
// Simulate user authentication and populate userInfo
req.userInfo = {
id: req.params.id // Extract the id from request params
// Add other user information if required
};
next();
});
// Define routes
// Route for '/users/:id' where you want to enforce permission check
app.get('/users/viewFiles/:id', authMiddleware('view_files'), (req, res) => {
// If middleware allows the request to pass through, handle the route logic here
if (req.authorized === 'authorized') {
res.send('You have access to this user route');
} else {
res.status(403).send('You are not authorized to access this user resource');
}
});
// Route for '/admin/deleteVendorFiles/:id' where you want to enforce permission check
app.get('/admin/deleteVendorFiles/:id', authMiddleware('delete_vendor_file'), (req, res) => {
// If middleware allows the request to pass through, handle the route logic here
if (req.authorized === 'authorized') {
res.send('You have access to this admin route');
} else {
res.status(403).send('You are not authorized to access this admin resource');
}
});
// Start the server
const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
console.log(`Server is running on port ${PORT}`);
});
```
This code sets up your Express application on port 3000 where specific routes are protected using a custom middleware called `authMiddleware`.
This middleware, imported from the `auth.js` file, integrates with Permify for permission checks. Below are routes being protected by the Middleware;
**Routes protected by the `authMiddleware`**:
- Route for `/users/viewFiles/:id`: This route ensures that only users have permission to view files can access this route.
- Route for `/admin/viewFiles/:id`: This route ensures that only admins who have permission to delete vendor files can access this route.
By applying the `authMiddleware` to these routes, access is restricted based on the permissions granted by Permify.
Let's test our implementation!
<h2 id="testing-rbac-implementation">Testing RBAC Implementation</h2>
Let's say we have a user with userID `alice`, Let's test to see if alice can access the `/users/viewFiles/` API endpoint which is only accessible by admins, managers or members that are not agents as we defined in our schema earlier in this article.
As expected, the UserID `alice` doesn't have access to this API endpoint, Let's give `alice` the member role using Permify Nodejs client's [data.write](https://docs.permify.co/api-reference/data/write-data) method:
```js
// write-relationship.js
const permify = require("@permify/permify-node");
const client = new permify.grpc.newClient({
endpoint: "localhost:3478",
})
client.data.write({
tenantId: "t1",
metadata: {
schemaVersion: ""
},
tuples: [{
entity: {
type: "organization",
id: "1"
},
relation: "member",
subject: {
type: "user",
id: "alice"
}
}]
}).then((response) => {
// handle response
console.log(response)
})
```
Let's run this code and try visiting the `/users/viewFiles/` API endpoint using Postman.
Now, after running the code, Alice can now successfully access the `/users/viewFiles/` API endpoint.
**Source Code:** All the code snippets featured in this article can be found in the corresponding [GitHub Repository](https://github.com/EbukaNduka/PERMIFY-RBAC-APP).
<h2 id="conclusion">Conclusion</h2>
It's important to recognize that authorization isn't a one-time setup; it's an ongoing process.
Therefore, it's imperative to regularly review your model, conduct thorough testing, and adapt it as your application evolves.
This guide serves as a solid foundation for implementing RBAC in your Node.js application.
However, don't hesitate to delve deeper and tailor the RBAC model to precisely fit your unique requirements.
By harnessing the capabilities of Permify, you can streamline permission management and cultivate a resilient and secure application environment.

in this post we're going to over two features of php that help make recursion easier: the [`RecursiveIterator`](https://gbh.fruitbat.io/2024/06/04/php-doing-recursion-with-recursive-iteratoriterators/) interface, which provides us with methods and features that make writing recursive functions easier, and the dreadfully-named [`RecursiveIteratorIterator`](https://gbh.fruitbat.io/2024/06/04/php-doing-recursion-with-recursive-iteratoriterators/) class which we can use to flatten down arbitrarily-deep data structures.
<figcaption>php to developers: “say ‘iterator’ five times fast”</figcaption>
we'll be building a recursive function using `RecursiveArrayIterator`, starting with a simple loop and working up to the full function. then we'll look at how leverage `RecursiveIteratorIterator` to smash that nested array into a single level so we can extract data, either with a simple loop or a more-complex-but-powerful call to `iterator_apply`.
## our sample array
all of the examples here are going to use the following sample array that represents an underwhelming collection of record albums:
```php
$albums = [
'first_name' => 'grant',
'last_name' => 'horwood',
'albums' => [
[
'title' => 'pottymouth',
'artist' => 'bratmobile',
'year' => 1993,
],
[
'title' => 'monks music',
'artist' => 'monk, thelonious',
'year' => 1957,
],
],
];
```
this array contains three top-level elements, one of which (`albums`) is an array of arrays. this is good stuff for recursion.
## the `RecursiveIterator` interface
here are the two main things we need to know about the `RecursiveIterator` interface:
1. **it's an interface:** `RecursiveIterator` doesn't actually do anything itself, it's just an interface that defines behaviour. if we want something usable, we have to look at classes that implement `RecursiveIterator`; classes like [`RecursiveArrayIterator`](https://www.php.net/manual/en/class.recursivearrayiterator.php) (for handling arrays) and [`RecursiveDirectoryIterator`](https://www.php.net/manual/en/class.recursivedirectoryiterator.php) (for handling filesystems).
2. **it doesn't actually do any recursion:** classes that implement `RecursiveIterator` don't do recursion for us. what they do is provide tools to help us build our own recursive functions more easily.
that may seem disappointing, but it shouldn't be: those tools that `RecursiveIterator` provide are useful. let's look at the three of them.
* **`hasChildren()`:** a data structure of arbitrary depth, like an array, can have values that are, themselves, arrays. the `hasChildren` method tests if the value we're looking is an array itself. we use this to test when we need our recursive function to actually recurse. it returns a boolean.
* **`getChildren()`:** if `hasChildren` returns `true` then we're going to need to need to get an iterator of current value so we have something to recurse with. that's what `getChildren` does.
* **a cursor:** as we loop over our `RecursiveIterator`, there's an internal cursor that keeps track of where we are in the array. this allows us to call methods like `hasChildren` for the current element. this is very handy.
if that didn't make immediate sense, don't worry; we're going to go over building a recursive function with `RecursiveIterator` step by step, starting with a not-very-useful loop.
## a simple (and not-very-useful) loop with `RecursiveArrayIterator`
because `RecursiveArrayIterator` is an iterator, we can use it in a `foreach` loop. let's do that.
```php
$rai = new RecursiveArrayIterator($albums);
foreach($rai as $k => $v) {
@print "$k => $v".PHP_EOL;
}
```
this is pretty straighforward: we create a new instance of `RecursiveArrayIterator` with our array and then do a `foreach`, printing out keys and values. the results are underwhelming.
```
first_name => grant
last_name => horwood
albums => Array
```
this is straight iterator behaviour; our loop went over the top level of the array and that's it. to start building a recursive function that does what we want, we're going to need to use `RecursiveIterator`'s `hasChildren` and `getChildren` methods.
## using `hasChildren`
as the name implies, the purpose of `hasChildren` is to determine if the current value is an array that can build an iterator from. let's add `hasChildren` to our disappointing loop.
```php
$rai = new RecursiveArrayIterator($albums);
foreach($rai as $k => $v) {
print $k;
if($rai->hasChildren()) {
print " has children";
}
print PHP_EOL;
}
```
here, we test if the value of the current element is an array, ie. it has a number of 'child' elements, and print out 'has children' if it is. the output is:
```
first_name
last_name
albums has children
```
---
ℹ️ **important note about cursors:** we see here that we call the method `hasChildren` on `$rai`, the `RecursiveArrayIterator` object itself. we can do this because `RecursiveArrayIterator` has an internal cursor pointing to the current element we're looping over. as we loop, this cursor advances to the next element so that when we call methods on the iterator object it's always for the element we're working on.
---
## once we have children, we can `getChildren`
now that we know `albums` has children, we can get a new `RecursiveArrayIterator` object for that array with `getChildren` and iterate over that. for instance:
```php
$rai = new RecursiveArrayIterator($albums);
foreach($rai as $k => $v) {
print $k." => ";
if($rai->hasChildren()) {
$rai2 = $rai->getChildren();
foreach($rai2 as $k2 => $v2) {
@print PHP_EOL." $k2 => $v2";
}
}
else {
print $v;
}
print PHP_EOL;
}
```
the biggest change we have made here is that, when `hasChildren` returns `true`, we get a new `RecursiveArrayIterator` object for those children with `getChildren` and then loop over that. the output is:
```
first_name => grant
last_name => horwood
albums =>
0 => Array
1 => Array
```
now we have all the tools to build a recursive function that will handle our entire array.
## at last: building a recursive function that will handle our entire array
upgrading our loop to a recursive function now only requires us to do two things:
1. put our loop in a function
2. have our function call itself when `hasChildren` return `true`
that's literally it. let's look:
```php
$rai = new RecursiveArrayIterator($albums);
function recurse(RecursiveArrayIterator $rai) {
foreach($rai as $k => $v) {
if($rai->hasChildren()) {
recurse($rai->getChildren());
}
else {
print "$k => $v".PHP_EOL;
}
}
}
// call our recursive function
recurse($rai);
```
our function accepts one argument, a `RecursiveArrayIterator` object. when we call that function, it loops over the top level of that array, printing out key/value pairs. when it encounters a value that `hasChildren`, it creates a new iterator with `getChildren` and then calls itself with that new iterator as an argument, looping over the next level down of the array. this keeps going until the first loop runs out of elements.
the output looks like this
```
first_name => grant
last_name => horwood
title => pottymouth
artist => bratmobile
year => 1993
title => monks music
artist => monk, thelonious
year => 1957
```
this is great stuff. except that we've lost the structure of our array. it's been 'flattened' down to one level.
of course, this can still be useful. lots of languages have built-in 'flattening' commands to do precisely this (i write a lot of scala and use the [`flatten`](https://allaboutscala.com/tutorials/chapter-8-beginner-tutorial-using-scala-collection-functions/scala-flatten-function-example/) method all the time).
but maybe we want to keep that structure. for that we need to add an accumulator.
<figcaption>a successful recursion</figcaption>
## adding an accumulator to our function
as the name implies, an accumulator is a variable where we accumulate the results of our recursive function while it executes. when our recursion is done, we return it. let's add one to our existing function:
```php
$rai = new RecursiveArrayIterator($albums);
function recurse(RecursiveArrayIterator $rai, Array $accumlator) {
foreach($rai as $k => $v) {
if($rai->hasChildren()) {
// add the return of our next call to recurse to our accumulator
$accumlator[$k] = recurse($rai->getChildren(), []);
}
else {
// add the key/value pair to the accumulator
$accumlator[$k] = $v;
}
}
return $accumlator;
}
// call our recursive function with an empty accumulator
$accumlator = recurse($rai, []);
// see the results
print_r($accumlator);
```
here, our accumulator is an array. we pass in an empty one when we call `recurse`, and in our function body instead of printing out our key/value pairs, we add them to the accumulator. when our function terminates, the accumulator is returned.
looking at the return value, we notice that the structure has been maintained. in fact, it is the exact same array as the one we passed to our function. success! kind of.
building a function that returns the same array it was passed is not exactly groundbreaking functionality. what we probably want to do with our recursive function is either transform or filter out some of those values.
we can do that, of course, by adding some code to the line where we assign a value to the accumulator. for instance, if we want to uppercase all of our values, we could add `strtoupper` like so:
```php
$accumlator[$k] = strtoupper($v);
```
or, if we wanted remove the `year` element from every album, we could filter it.
```php
if($k != 'year') {
$accumlator[$k] = $v;
}
```
now we're doing something useful!
## building a more generic solution
so, now we can traverse our entire array and apply the custom filters or transformations of our choosing. this is good, but it would be much better if we could write up a generic recursion function that took filters and transformations as arguments. let's do that.
```php
$rai = new RecursiveArrayIterator($albums);
/**
* Traverse the array applying $filter to each key and $transformer to each value
*
* @param RecursiveArrayIterator $rai
* @param Array $accumlator
* @param callable $filter
* @param callable $transformer
* @return array
*/
function recurse(RecursiveArrayIterator $rai, Array $accumlator, callable $filter = null, callable $transformer = null): Array {
// a default filter that removes nothing
$filter = $filter ?? fn($n) => true;
// a default transformer that changes nothing
$transformer = $transformer ?? fn($n) => $n;
foreach($rai as $k => $v) {
if($rai->hasChildren()) {
$accumlator[$k] = recurse($rai->getChildren(), [], $filter, $transformer);
}
else {
// test the filter and apply the transformer
if($filter($k)) {
$accumlator[$k] = $transformer($v);
}
}
}
return $accumlator;
}
// filter to apply to each key. remove elements with key 'year'
$filter = fn($n) => $n != 'year';
// transformer to apply to each value. apply uppercase to all values
$transformer = fn($n) => strtoupper($n);
// call our recursive function with an empty accumulator
$accumlator = recurse($rai, [], $filter, $transformer);
// see the results
print_r($accumlator);
```
we've added two new arguments to our function here:
* **`$filter`:** this is a callable that accepts the key of our array element as an argument. it performs a test on the key and returns a boolean. in the above example, we test if the key is `year` and return `false` if it is. this callable is applied to each array element and only the elements that return `true` are added to our accumulator.
* **`$transformer`:** a callable that accepts the value of the element as an argument and applies some functionality to that value. in the example, we uppercase the value with `strtoupper`. the transformed value will be added to the accumulator when we run this example code, we get this:
```php
Array
(
[first_name] => GRANT
[last_name] => HORWOOD
[albums] => Array
(
[0] => Array
(
[title] => POTTYMOUTH
[artist] => BRATMOBILE
)
[1] => Array
(
[title] => MONKS MUSIC
[artist] => MONK, THELONIOUS
)
)
)
```
all the elements keyed with `year` have been removed and `strtoupper` has been applied to all the values. exactly what we asked for.
if we pass `null`'s for either `$filter` or `$transformer`, the default callables are used: no filtering, no transformation.
this technique has real-world uses. for the [day job](https://fruitbat.studio) a long time ago, i wrote a package to [redact passwords and such from arbitrary json](https://github.com/gbhorwood/Redactem) so we wouldn't be storing those hacker goodies in our log files; recursion with filters and transformers was the solution.
## using `RecursiveIteratorIterator` to flatten arrays
remember back when we did the first recursion and our multi-dimensional array came back flattened to one level?
we can achieve that functionality in a far-less cumbersome way by using the `RecursiveIteratorIterator` class. for example:
```php
$rai = new RecursiveArrayIterator($albums);
// create a RecursiveIteratorIterator object
$rii = new RecursiveIteratorIterator($rai);
// loop over the RecursiveIteratorIterator
foreach($rii as $k => $v) {
print "$k => $v".PHP_EOL;
}
```
this loop replaces our entire recursive function and spits out the same results, a flattened array:
```
first_name => grant
last_name => horwood
title => pottymouth
artist => bratmobile
year => 1993
title => monks music
artist => monk, thelonious
year => 1957
```
essentially, the `RecursiveIteratorIterator` is just an iterator that loops over our `RecursiveArrayIterator`and all the `RecursiveArrayIterator`s it contains. it's an iterator that iterates over an iterator and all the iterators that iterator contains, recursively. that sentence would have sounded ridiculous at the beginning of this post, but now it makes perfect sense.
## using `iterator_apply` on all this stuff
flattening an array can have a lot of benefits. for instance, if we wanted to just get all of the artists in our album collection, we could write a recursive function with `RecursiveArrayIterator` and extract that information, or we could just flatten the whole thing with `RecursiveIteratorIterator` and grab every value keyed `artist`. the flattening approach is way faster and easier.
there are a couple of ways to extract data from a flattened array, but the first one i'll mention is way that will not work: `array_filter`.
at first glance, `array_filter` seems perfect for the job. we want to filter our array to get only `artist`, after all. however, `array_filter` preserves keys. this is a problem since, if we look at our output above, we have two elements with the same key: `artist`. with `array_filter`, those keys would all get clobbered and we would wind up with only one value: the last one. not good.
the most direct approach is to simply filter in our `foreach` loop.
```php
$rai = new RecursiveArrayIterator($albums);
$rii = new RecursiveIteratorIterator($rai);
$artists = [];
foreach($rii as $k => $v) {
if($k == "artist") {
$artists[] = $v;
}
}
print_r($artists);
```
here, we loop over our `RecursiveIteratorIterator` and if the key is `artist` we add it to our `$artists` array. the result is an array of artist names. perfect.
or we could use `iterator_apply`.
`iterator_apply` applies a function to each element in an iterator. in this sense is kind of like `array_map`. let's look at how we would get our artists using it:
```php
$rai = new RecursiveArrayIterator($albums);
$rii = new RecursiveIteratorIterator($rai);
// our filtering function to extract only 'artists'
$filter = fn($n) => $n == 'artist';
$artists = [];
iterator_apply($rii,
function($n, $filter, &$artists) {
// test the key with the filter
if($filter($n->key())) {
$artists[] = $n->current();
}
return true;
},
[$rii, $filter, &$artists]);
print_r($artists);
```
looking at `iterator_apply`, we see it takes three arguments. the first argument is our iterator; very straightforward.
the second a third arguments define the function we want to apply to each iterator element. argument two is the function itself, a callable. the third argument is an array representing all the arguments that we are passing to that function. if the function we defined in argument two takes five arguments, the array here needs to have five elements. the first argument of our function and, correspondingly, the first element of our array, should always be the iterator itself.
in the example above, the function we're passing to iterator_apply takes three arguments: the iterator, a callable we're using to filter the elements in the iterator, and an accumulator called `$artists`. we're passing `$artists` by reference so we can modify it in the function body and have the results available to us after execution is done.
in the body of the function, we get the key of the current element of the iterator by calling the `key()` method and pass it to our `$filter`, our callable that determines if that key is `artists`. if `$filter` returns true, we get the value of the current element of the iterator by calling the `current()` and add it to our accumulator `$artists`.
in all honesty, this approach is neither easy nor obvious and, as a result, most people just use `foreach` loops. but `iterator_apply` is quite powerful, especially if we have a complex or pre-existing function that we would like to apply. it's worthwhile knowing it exists, even if we have to re-read the manual every time we use it.

Antes mesmo de pensarmos em começar a desenvolver aplicações ou governanças para provisionar e gerenciar ambientes com foco em agilidade e com foco no negócio, arquitetos de solução acabam trabalhando em inúmeras opções para desenvolver `architecture designs` que atendam as necessidades de negócio.
Existem muitos meios de desenvolver uma solução, onde devemos sempre conseguir as informações certas baseadas em necessidades (requisitos) de usuários (clientes), considerando custos, performance, escalabilidade e disponibilidade da soluções disponibilizadas.
Aqui vamos entender sobre as vantagens de várias arquiteturas diferentes e também olhar para algumas demonstrações de quando utiliza-las.
A primeira arquitetura que iremos nos aprofundar é a **Arquitetura multicamada** que também pode ser chamada de **n-tier layered architecutre**. Essa abordagem em camadas apoia o desenvolvimento incremental de sistemas, onde, a medida que uma camada é desenvolvida, alguns dos serviços fornecidos por ela podem ser disponibilizados aos usuários ou desenvolvedores.
Nesse tipo de arquitetura é importante utilizarmos princípios de design *loosely coupled*¹ e também devemos nos atentar a atributos de *escalabilidade*² e *elasticidade*³. Uma arquitetura multicamada provê flexibilidade para adicionar novas funcionalidades em cada camada sem perturbar as outras camadas.
Em termos de segurança, nós podemos deixar cada camada isolada das outras, ou seja, caso uma camada for comprometida as outras camadas não serão impactadas. Isso acaba nos trazendo benefícios, onde podemos fazer troubleshootings e gerenciamentos de incidentes de uma forma mais rápida, identificando assim os problemas e de qual camada eles vem.
A arquitetura mais comum em multicamadas é a *three-tier architecture* (Arquitetura de três camadas) onde são divididas em:
1. **Camada de apresentação (Presentation layer)**: onde é responsável pela a interface do usuário ou uma camada de apresentação genérica.
2. **Camada de aplicação (Logic Layer):** onde normalmente os dados são processados e implementa as regras de negócio da aplicação.
3. **Camada de dados (Data layer):** no qual os dados são armazenados e gerenciados, fornecendo à camada de lógica os dados necessários para execução de processos.
O diagrama abaixo, mostra um exemplo básico de como podemos implementar uma arquitetura multicamadas para uma aplicação web que performa funções, como por exemplo, assistir um filme ou até mesmo fazer alguma compra:
Podemos constatar as três camadas:
1. **Web-layer** (Front-end): Nossa camada de apresentação
2. **Application-layer** (Back-end): Nossa camada de aplicação
3. **Database-layer**: Nossa camada de dados
### A camada de apresentação
A camada web, também conhecida como camada de apresentação, provê as interfaces onde o usuário vai interagir com a aplicação. A camada web é a sua visualização da aplicação, por exemplo, um site ou até mesmo um e-commerce onde você faz compras.
Normalmente desenvolvedores criam essa camada de apresentação usando tecnologias como HTML, CSS, JavaScript e seus frameworks (React, Angular, Vue e etc.). Essa camada coleta as informações do usuário e passa para a camada de aplicação, por exemplo, um formulário de cadastro.
### A camada de aplicação
A camada de aplicação, pode ser resumida em uma camada onde a lógica do negócio acontece, é onde o core do produto fica. A camada de apresentação coleta os dados e informações dos usuários e passa esses dados para que sejam processados pela a camada de aplicação, para termos algum resultado esperado. Por exemplo, um site de compras como o da **Amazon**, os usuários pode filtrar produtos por ele ser **prime** ou não e ordenar em ordem *crescente* ou *decrescente*. Em retorno a camada de aplicação retorna os dados que foram capturados e passam para a camada de aplicação para que a mesma possa performar as regras de negócio.
Geralmente numa arquitetura de três camadas, todos os algoritmos e lógicas ficam na camada de aplicação.
A camada de aplicação é o centro do negócio que performa as regras de negócio nos dados que estão armazenados na camada de dados.
### A camada de dados
A camada de dados ou também conhecida como *Database Layer* ou *Data tier* é responsável por armazenar todas as informações relacionadas aos usuários e suas transações. Essencialmente ela contem qualquer dado que necessite ser persistido na camada de dados. Essa informação pode ser reenviada para a camada de aplicação para o processamento de alguma regra de negócio e eventualmente é renderizada para o usuário final na camada de apresentação.
## Conclusão
Falamos aqui de como a arquitetura de multicamadas pode ser utilizada e demos um exemplo de uma arquitetura de três camadas para uma aplicação web.
Toda a jornada através dessa arquitetura nos apresentou benefícios e uma visão abrangente de suas camadas e responsabilidades. É importante ressaltar que ao estruturar um sistema com camadas bem definidas, com responsabilidades claras e interfaces bem documentadas, os benefícios acabam se estendendo desde a agilidade no desenvolvimento até mesmo a confiabilidade e resiliência de seu sistema a longo prazo.
Lembre-se que, como qualquer outra ferramenta, a efetividade da arquitetura depende de sua implementação adequada. Por isso é importante passar por conceitos da engenharia de requisitos contendo os requisitos funcionais e não funcionais de seu negócio.

As an early-stage startup, you can afford to spend time building things that are not core to your product.
This might be controversial, but my experience has been to pick and choose the battles you want to face.
While all startups are different, we eventually encounter a common dilemma: "Do you buy a solution or build one yourself?"
Some startup teams opt for the scrappy approach, building in-house tools/ finding an open-source solution, while others default to buying a SaaS vendor.
Statsig was no different. However, since the founding engineering team were all ex-Meta (Facebook), they looked to replace the tooling they used before.
## Sharing your tech stack is cool, but sharing your story is more helpful
The biggest takeaway for me while sharing their story is that posts about your tech stack might be cool on social, but they leave out the most important part: how you arrived there. What battles did you face and what tradeoffs did you make trying different tools?
Below is a full breakdown of Statsig's tooling & tech stack, and we wrote about the struggles we faced along the way to get there.
(...My favorite story is how we tried to save money by using an open-source Notion alternative. Yeah, that didn't work out.)

In [part 1](https://www.resourcely.io/post/death-of-devsecops-part-1-the-rise-of-cloud-and-devops) of this series, I covered the history of security in the early days of the cloud revolution. Circa 2014, DevOps practices started to be adopted by security teams, resulting in the era of DevSecOps. We’ll cover this concept, the dreams of so many, and the reality that ensued.
## Security is a laggard
One pattern that I have observed about security teams is they are slow to change. Security was not a forethought in the pre-Internet days, because it was never really a problem. These teams were only created after internet adoption started becoming more widespread, and they integrated into the waterfall processes of the early days - because that is how development teams worked with infrastructure teams.
After cloud infrastructure became available, DevOps as a practice started to spread like wildfire as we covered in part 1. Why did it take security teams 10 years to fully adopt agile practices and integrate security into DevOps?
Traditional security focused on building a strong perimeter for a static environment. While the rapid iteration and change of DevOps was a boon to development teams, it was naturally uncomfortable for security teams.
New tools and processes meant new attack vectors: something security teams are naturally wary of
Security teams were not incentivized to move quickly, given they were a standalone, siloed organization
They started first by trying to apply legacy processes such as waterfall-style review and approval, to an agile methodology - and this failed
## From DevOps to DevSecOps: the dream
By ~2015, it had become apparent that security had lost their gate. As DevOps became the de facto standard, established security teams started losing political capital as they impacted development lifecycles by resisting change. As challenger companies saw success by shipping quickly and cheaply, it became obvious that established security waterfall style could not continue. VC money poured into challenger tech companies that applied the same concepts to security that they were applying to development: shifting decision-making and implementation onto the engineer.
DevSecOps appears to have been coined around 2014, usually attributed to [Shannon Lietz of Intuit](https://www.linkedin.com/pulse/intuits-devsecops-war-games-gamification-culture-hacking-e-weeks/). The promise of DevSecOps was to further speed development lifecycles without sacrificing security, by embedding security choices into DevOps (hence DevSecOps). Security and software leaders thought they could:
- Save money on security teams by turning them into guideline providers
- Get security for free from developer teams, who would make practical choices to enforce guidelines
- Proactively support developers with automation
However, the dream of DevSecOps ignores some realities that make it a failed practice.
## DevSecOps: The reality of today
As DevSecOps was adopted throughout the late ‘10s and early ‘20s, it became clear that the benefits did not materialize as promised. Don’t get me wrong, there have been some improvements:
- Some integration into change management: CI process that can enforce security reviews before deployment happens
- Multi-environment support: Build pipelines can progress the same build through environments
This marginal progress isn’t enough. There are too many vulnerabilities, too many issues, and not enough time for the manual world of security that we’ve built for ourselves. It turns out that pushing security into DevOps processes sucks for all of those involved. Security teams are overwhelmed, spending all their time measuring faults and making lists of vulnerabilities. Devs are spending unnecessary cycles on security config, when they want to do actual development.
We’ve been left with the worst of both worlds with DevSecOps of today. Why is that?
### Devs aren’t security or infra experts
One of the primary assumptions of DevSecOps was that developers would be able to make security and infrastructure-related decisions that were correct. Turns out that in practice, this is not the case. Why? Developers aren’t security or infrastructure experts, and they don’t have the time to become experts. Instead of addressing the fundamental problem, we try to up-skill our developers on security and force training hell onto everybody involved.
Consider a scenario where a developer wants to deploy using an Azure VM and write from that VM to blob storage, and a security team stipulates that it should only be deployed within a company’s VPC. Only an experienced Azure infrastructure expert would be able to configure this in a time-efficient way: this requires 5+ different resources, and if you’re using something like Terraform it requires even more expertise!
### Automation has failed us
Another key expectation by early DevSecOps experts was that automation would make up for developer time. Platform teams started to emerge in the late ‘10s and early ‘20s, providing tools for developers to move faster. To date, security automation is primarily a reactive function: we still expect configuration decisions to be made by developers, and we serve them a list of issues to fix after the fact.
### Worst of both worlds
DevSecOps has evolved into the worst of both worlds. With developers that aren’t experts in security or infrastructure, and a lack of automation, we now have:
- Rampant misconfiguration
- Frequent incidents and outages
- Constant triage of issues
- Reactive posture management, resulting in huge backlogs of security issues
- Overwhelmed developers who don’t want to engage with security
- A lack of clear ownership means when there’s a problem, it is unclear who needs to act
This means the Sec in DevSecOps hasn’t kept up its end of the bargain. We’ve only marginally improved (and that’s debatable), and we’re only incrementally more secure.
### The answer? Secure-by-default
In part 3, we will cover the future: secure-by-default. New tools and technologies mean that we can take the burden of security and infrastructure configuration off developers’ plates, allowing software teams to ship quickly and companies to preserve security and reliability.
