Beberapa hari lalu ada 5 orang yang tanya mau punya aplikasi kwetansi. 

Jadi ketika ada yang transaksi secara offline bisa di catat, di cetak, di kirim 

Tercatat di database 
Diprint bukti setornya 
Dikirim juga ke nomor WhatsApp klien

Cocok untuk segala bisnis mulai dari jasa atau produk fisik & digital.

Tanpa menunggu lama aku konsultasikan ke tim untuk dibuatkan aplikasi tersebut !! 

Dan beberapa hari lagi insyallah saya rilis 
Tunggu ke hadirannya di channel saya yaa

Excalidraw is built using the following technologies:

1. JavaScript – Core programming language used to create the app's logic.
2. React – Excalidraw is a React-based project, which allows the creation of reusable components and efficient state management.
3. TypeScript – Strongly typed version of JavaScript used for better code reliability and development efficiency.
4. HTML5 Canvas – The drawing surface is based on the HTML5 <canvas> element for rendering shapes and lines.
5. Redux – State management tool used to manage application state and handle complex state updates.
6. WebRTC – Used for real-time collaboration, allowing multiple users to work on the same drawing simultaneously.
7. PWA (Progressive Web App) – Excalidraw is available as a PWA, which means it can work offline and be installed as a standalone app.
8. IndexedDB – Used to store drawings and session data locally in the browser.
9. CRDT (Conflict-free Replicated Data Type) – Handles real-time collaboration and ensures consistency across multiple users editing the same drawing.

Excalidraw is an open-source project, and its source code is available on [GitHub](https://github.com/excalidraw/excalidraw).

Dalam konteks OSINT (Open Source Intelligence), intelligent merujuk pada proses pengumpulan, analisis, dan interpretasi informasi yang tersedia secara publik untuk menghasilkan wawasan strategis dan taktis. OSINT menggunakan berbagai sumber seperti media sosial, situs web, laporan pemerintah, dan forum publik untuk mengidentifikasi ancaman, peluang, atau pola tertentu yang berguna dalam pengambilan keputusan. Intelligent dalam OSINT berarti mampu menyaring data yang relevan, memverifikasi keabsahan informasi, dan menyajikannya dalam bentuk yang mudah dimengerti dan dapat ditindaklanjuti.
Nice! If you're considering both centralized and decentralized servers, here’s how you can use them effectively depending on your needs.


---

1. When to Use a Centralized Server?

Best for: Businesses, websites, databases, and cloud storage.
Why?

Easier to manage and secure.

Faster processing and retrieval of data.

Controlled access (good for sensitive data).


Example:

A company website hosted on a dedicated server.

A business using Google Drive or OneDrive for team collaboration.



---

2. When to Use a Decentralized (or Distributed) Server?

Best for: File sharing, blockchain, P2P applications, and high-redundancy systems.
Why?

No single point of failure (if one node/server goes down, the system still runs).

More privacy and resistance to censorship.

Works well for open-source or community-driven projects.


Example:

Torrenting files using a P2P network.

Cryptocurrency networks like Bitcoin.

A decentralized web app (dApp) running on blockchain.



---

Using Both Together (Hybrid Approach)

Some systems use a mix of centralized and decentralized servers. This balances control, speed, and redundancy.

Examples of Hybrid Systems:

CDNs (Content Delivery Networks): Like Cloudflare or Akamai, which store website data on multiple distributed servers but still operate under a centralized system.

Hybrid Cloud Services: Businesses use private (centralized) servers for critical data and decentralized cloud storage for backups.

Blockchain with Cloud Integration: Some companies use blockchain for security (decentralized) but store data on a centralized server.


Would you like guidance on setting up a system using both? Or are you just exploring the concepts?
