When disassembled it looks this way

![Disassembled puzzle](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/vfdu45ezrgk9h7oez05t.png)

Quite hard puzzle I would say. I decided to write a C# program to solve it.

```C#
const int dim = 3;
int[] snake = { 3, 3, 3, 3, 2, 2, 2, 3, 3, 2, 2, 3, 2, 3, 2, 2, 3 };

bool[,,] used = new bool[dim, dim, dim];

Stack<Point> path = new();
used[0, 0, 0] = true;

if (DFS((0, 0, 0), 0, (0, 0, 0))) {
    foreach (var m in path.Reverse()) {
        Console.WriteLine(m);
    }
};

bool DFS(Point p, int idx, Point m) {
    if (idx >= snake.Length) {
        return false;
    }

    if (p == (dim - 1, dim - 1, dim - 1) && idx == snake.Length - 1) {
        Console.WriteLine("done!");
        return true;
    }

    foreach (var move in Point.Moves) {
        if (move == m) { continue; }
        var len = (snake[idx] - 1);
        var nextLen1Or2 = p + (move * len);
        var nextLen1 = p + move;
        if (!nextLen1Or2.InCube(dim)) { continue; }
        if (used[nextLen1Or2.X, nextLen1Or2.Y, nextLen1Or2.Z]) { continue; }
        if (used[nextLen1.X, nextLen1.Y, nextLen1.Z]) { continue; }
        path.Push(move);
        used[nextLen1Or2.X, nextLen1Or2.Y, nextLen1Or2.Z] = true;
        used[nextLen1.X, nextLen1.Y, nextLen1.Z] = true;
        if (DFS(nextLen1Or2, idx + 1, move)) {
            return true;
        }
        path.Pop();
        used[nextLen1Or2.X, nextLen1Or2.Y, nextLen1Or2.Z] = false;
        used[nextLen1.X, nextLen1.Y, nextLen1.Z] = false;
    }

    return false;
}

public record struct Point(int X, int Y, int Z) {
    public static readonly Point[] Moves = { (-1, 0, 0), (0, -1, 0), (0, 0, -1), (1, 0, 0), (0, 1, 0), (0, 0, 1) };
    public static Point operator +(Point a, Point b) => new(a.X + b.X, a.Y + b.Y, a.Z + b.Z);
    public static Point operator *(Point a, int f) => new(a.X * f, a.Y * f, a.Z * f);
    public static implicit operator Point((int X, int Y, int Z) p) => new(p.X, p.Y, p.Z);
    public readonly bool InCube(int size) => X >= 0 && X < size && Y >= 0 && Y < size && Z >= 0 && Z < size;
}
```

So the solution is:

```
Point { X = 1, Y = 0, Z = 0 }
Point { X = 0, Y = 1, Z = 0 }
Point { X = -1, Y = 0, Z = 0 }
Point { X = 0, Y = 0, Z = 1 }
Point { X = 1, Y = 0, Z = 0 }
Point { X = 0, Y = 0, Z = -1 }
Point { X = 1, Y = 0, Z = 0 }
Point { X = 0, Y = -1, Z = 0 }
Point { X = -1, Y = 0, Z = 0 }
Point { X = 0, Y = 0, Z = 1 }
Point { X = 0, Y = 1, Z = 0 }
Point { X = 0, Y = 0, Z = -1 }
Point { X = 1, Y = 0, Z = 0 }
Point { X = 0, Y = 0, Z = 1 }
Point { X = 1, Y = 0, Z = 0 }
Point { X = 0, Y = 1, Z = 0 }
```

## AWS Amplify UI: Build UI Fast with Amplify on React

[AWS Amplify UI](https://ui.docs.amplify.aws/) is a set of React components that make it easy to build beautiful and responsive user interfaces. The components are built on top of the Amplify framework, which provides a unified way to connect your app to backend services.

Amplify UI is designed to be easy to use, even for beginners. The components are well-documented and there are plenty of examples to help you get started.

In this blog post, we'll show you how to use Amplify UI to build a simple todo app.

## Getting Started

The first step is to install Amplify UI. You can do this with the following command:

```bash
npm install @aws-amplify/ui
```

Once Amplify UI is installed, you can start using the components in your app.

## Creating a Todo List

To create a todo list, we'll use the following components:

- `AmplifyCard`: This component is used to create a card that displays a todo item.
- `AmplifyInput`: This component is used to create a text input field.
- `AmplifyButton`: This component is used to create a button.

Here's the code for our todo list:

```js
import React from 'react';
import { AmplifyCard, AmplifyInput, AmplifyButton } from '@aws-amplify/ui';

const TodoList = () => {
	const [todos, setTodos] = useState([]);

	const addTodo = () => {
		const newTodo = {
			text: e.target.value
		};

		setTodos([...todos, newTodo]);
	};

	return (
		<div>
			<AmplifyCard>
				<h2>Todo List</h2>
				<ul>
					{todos.map((todo, index) => (
						<li key={index}>
							{todo.text}
							<AmplifyButton onClick={() => setTodos(todos.filter((t) => t.id !== todo.id))}>
								Delete
							</AmplifyButton>
						</li>
					))}
				</ul>
			</AmplifyCard>

			<AmplifyInput placeholder="Enter a new todo" onChange={(e) => addTodo()} />
		</div>
	);
};

export default TodoList;
```

This code will create a todo list with a text input field and a button. When you enter a todo item in the text input field and click the button, the item will be added to the list.

## What is next?

[AWS Amplify UI](https://ui.docs.amplify.aws/) is a powerful tool that can help you build beautiful and responsive user interfaces. The components are easy to use and well-documented, making them a great choice for beginners and experienced developers alike.

If you're looking for a way to build user interfaces quickly and easily, then [AWS Amplify UI](https://ui.docs.amplify.aws/) is a great option.

Serverless API Load Tester
Published: 2023-12-18 06:40:12


Hello everyone ✌🏻,
Recently I needed a load tester tool that simply sends requests to my Rest API. I created a simple project. Here is what I have come up with!
You can reach the [https://github.com/ahmettkartal/serverless-api-load-tester/](https://github.com/ahmettkartal/serverless-api-load-tester/) repo from here.

## Before You Begin
Make sure you have:

- AWS Account
- Node.js installed
- Serverless Framework installed
- AWS SQS queue created with default settings

Don't worry if you're new to configuring the Serverless Framework or setting up AWS credentials. You can follow this [documentation](https://www.serverless.com/framework/docs/getting-started). Also, you can follow up on how to setup AWS credentials from this [documentation](https://www.serverless.com/framework/docs/providers/aws/guide/credentials)

## Configuring the SQS Queue

1. This project sends requests using [AWS SQS](https://aws.amazon.com/sqs/). You can create a simple FIFO queue with default settings.
2. Once your queue is created, you'll need to update the queue ARN and URL in the `config.development.json` file under the `config` folder. Alternatively, you can set these variables in the `run.sh` file for local development.

3. Replace `YOUR_SQS_QUEUE_ARN_HERE` and `YOUR_SQS_QUEUE_URL_HERE`, with your actual queue information.

## Deploying the Project

1. Deploy the project to AWS using the Serverless Framework with this command:

```
serverless deploy --stage development
```
2. If you want to create a new stage, you have to create the stage's config file under the `config` folder with the stage's name. For example, for a stage called `production`, create a file named `config.production.json`.

## Running the Project

1. After the deployment process, you'll get an endpoint like `https://endpoint_key.execute-api.eu-central-1.amazonaws.com/development`. This URL serves as your base endpoint.

2. To add a request to the queue you can use the `{{url}}/load-tests` endpoint. Below, you'll find an example of sample data you can use:
```
{	
	"iteration" : 100,
	"request_data" : {
		"method" : "post",
		"url" :"YOUR_LOAD_TEST_ENDPOINT",
		"data" : {
			"key" :"value"
		},
		"headers" : {
			"Content-Type": "application/json"
		}
	}
}
```

> I used [webhook.site](https://webhook.site) for testing. It is a great tool.
> Also you can find the Postman collection at the repo

The `iteration` parameter denotes the number of requests, and the `request_data` configures Axios. 

That is it! Now you have your load tester tool 🥳. If you have additional ideas or any problems, please write me ✌🏻.
Geo-Distributed Face Template Storage in Face Recognition API
Tags: tutorial, ai, learning, security
Published: 2023-12-18 06:39:38

One of the key differences between the [Face Recognition API](https://luxand.cloud/face-recognition-api/https://luxand.cloud/face-recognition-blog/geo-distributed-face-template-storage-in-face-recognition-api/?utm_source=devto&utm_medium=geo-distributed-face-template-storage-in-face-recognition-api) and SDK is that the API provides geo-distributed storage for face templates. This storage is used to register people in the database and then search for them in photos using this database.

Examples include identifying individuals on your premises, searching for criminals, recognizing people at the checkout, two-factor authentication, and more.

The convenience of the API lies in the fact that this database is already available, eliminating the need to build this logic from scratch. You simply use the method to create a person in the database to populate it, and then use another method to search for these faces in photos.

## What Are Face Templates

To compare two individuals, neural networks use what are called face templates. In simple terms, these are a set of numbers that, according to the logic of the neural network, create an image of a person for it.

This is different from a photograph, as the template is closely linked to the neural network's structure. In programming, this is referred to as one-way hashing or lossy data archiving.

You cannot retrieve a photograph from this template, making storing the face template in the cloud extremely secure. It does not violate any personal data requirements.

However, in Luxand's cloud, you can also store photographs for convenience. For example, if you have an internal system where you need to display the face of the recognized person. For this, when creating a person, specify the parameter store=1.

We will upload this face to the CDN, and it will be accessible via a specific URL, which you will receive after uploading the person's image.

Enhance Security and Defeat Spoofing: A Comprehensive Guide to Liveness Detection Implementation
Tags: tutorial, ai, database, security
Published: 2023-12-18 06:35:28

[Liveness detection](https://luxand.cloud/liveness-detection-api/?utm_source=devto&utm_medium=geo-distributed-face-template-storage-in-face-recognition-api) is integral to enhancing security and verifying identities in sectors like banking, mobile payments, and access controls.

In today's digital security landscape, marked by a spike in identity fraud — with losses reaching $43.3 billion in the U.S. in 2022 — this technology is key for effective user authentication.

It combats fraud and identity theft by differentiating real individuals from false representations, such as photos, videos, or masks. This article delves into various liveness detection methods and introduces our novel anti-spoofing solution to this critical issue.

## Methods of liveness detection

### Passive Liveness Checks
Passive face liveness detection analyzes facial imagery in videos or photos, focusing on lighting and texture. This process is crucial for anti-spoofing, ensuring that the image is of a real person and not a fake.

Below is a practical example demonstrating how our system effectively discerns between genuine and fraudulent images:


### Active Liveness Checks
The method relies on the individual undergoing biometric authentication to perform specific actions such as blinking, smiling, raising eyebrows, nodding, slow blinking, nodding up and down, turning their head left and right, as well as bringing their hand to their face and rotating it around its own axis.

By capturing and analyzing these movements, the [liveness detection API](https://luxand.cloud/liveness-detection-api/?utm_source=devto&utm_medium=geo-distributed-face-template-storage-in-face-recognition-api) ensures reliable and accurate authentication.

This approach offers a high level of security, making it difficult to counterfeit, and provides robust protection in fraud prevention against unauthorized access, crucial for any application requiring facial-based authentication.

### Hybrid Liveness Method
Combining both passive and active checks, this method ensures quick verification, shifting to active liveness if passive data is insufficient​​.

A cross-platform graphical system monitor
Tags: rust, python
Published: 2023-12-18 05:58:14

Hi, Today I will introduce one graphical system monitor called "bottom". Bottom is a process/system visualization and management application that provides comprehensive system monitoring capabilities. 

It offers a real-time visualization of CPU usage over time, both at an average and per-core level. This allows users to easily identify and track CPU-intensive processes.In addition to CPU usage, Bottom also displays RAM and swap usage over time. This provides valuable insights into the memory utilization of the system, helping users identify potential memory issues or optimize their system's performance.Another feature of Bottom is its ability to display network I/O usage over time. This allows users to monitor network traffic and identify potential network-related issues.

Bottom also includes a range of widgets that provide additional information about the system. These include a disk capacity widget, temperature sensor widget, and battery usage widget. These widgets provide quick and convenient access to system information without having to navigate through multiple menus or applications.

Furthermore, Bottom has a process widget that displays information about running processes. Users can sort and search processes using the process widget, making it easier to identify specific processes or manage running programs.

One of the key features of Bottom is its support for kill signals. Users can send kill signals to processes to terminate them, which is useful for managing resource-intensive processes or responding to system crashes.Another noteworthy feature is its tree mode, which provides a hierarchical view of running processes, making it easier to navigate and manage process relationships.
Bottom is also cross-platform, supporting Linux, macOS, and Windows. This makes it a versatile tool that can be used on multiple platforms without the need for additional configurations or adaptations.

Lastly, Bottom offers extensive customization options. Users can control its behavior using command-line flags or a config file. This includes customizing color themes, modifying widget behavior, adjusting the layout of widgets, and filtering out entries in some widgets to tailor the display according to their specific needs or preferences.
