Tailscale: A Simpler, Smarter Way to Connect All Your Devices

on
Tailscale creates a private, encrypted network between your devices using WireGuard under the hood. Instead of “a VPN but complicated,” it acts more like: a mesh of private tunnels with identity-based access (your Google / Microsoft login = your authentication) and automatic NAT traversal (no port-forwarding nightmares) plus support for basically every platform on Earth Everything becomes part of your personal tailnet,  your own secure space. 1. Create your tailnet Go to https://tailscale.com/ Click Sign Up Choose the identity provider you want (Google, Microsoft, GitHub, Apple ID, etc.) That’s it. Your tailnet exists. 2. Install Tailscale on your first device On Windows Download the installer from: https://tailscale.com/download Run the .msi Sign in Approve the device curl -fsSL https://tailscale.com/install.sh | sh sudo tailscale up Then sign in via the browser page that opens. 3. Add your second device Once signed in, both devices will now appear ...

ChatRTX: Your Personalized Assistant by NVIDIA

on

Ever wished for a powerful AI chatbot like ChatGPT or Gemini, running on your PC and using your own files, without cloud uploads? NVIDIA's ChatRTX  makes this possible, bringing generative AI to your desktop.


Unlike cloud-based chatbots, ChatRTX runs entirely on your Windows PC. Your data remains private. This is ideal for privacy-conscious users or those handling sensitive information.  No internet connection is needed after setup!

ChatRTX uses Retrieval-Augmented Generation (RAG). You can point it to a folder of documents (.txt, .pdf, .doc/.docx, .xml) or YouTube URLs.  It uses this information to answer your questions. Imagine querying your project notes or research papers for summarized answers—a real productivity boost!

Using your NVIDIA RTX graphics card, ChatRTX often provides answers faster than cloud services, especially for local files.

NVIDIA also offers ChatRTX as a reference project. This benefits developers learning to build applications using technologies like TensorRT-LLM for optimizing AI models on RTX hardware.


You need a Windows 11 PC with an NVIDIA GeForce RTX 30-series, 40-series, or 50-series GPU (or equivalent professional cards) and at least 8GB of VRAM. This excludes many users without high-end systems. Updated drivers are also required.

Running locally, ChatRTX lacks access to constantly updated internet information. Its knowledge is limited to the base AI model (like Mistral or Llama) and your provided files. Don't expect current news unless you supply relevant documents.

ChatRTX's AI models, while powerful, are smaller than those powering cloud services. This may lead to less nuanced responses or inaccuracies.

As a tech demo, it may lack the polish or features of a commercial product. Setup might require technical expertise.

Running AI models locally uses significant GPU resources.  Heavy AI use alongside gaming or other demanding tasks may impact performance.


ChatRTX offers a promising glimpse of personalized, private AI. Securely querying local data is fantastic for productivity and specialized tasks. It's a step towards democratizing powerful AI.

However, the high hardware requirements are a barrier. It's clearly aimed at users with NVIDIA RTX hardware.

For tech enthusiasts, developers, and those with compatible hardware prioritizing privacy and local data, ChatRTX is worth exploring. It could become your personal digital assistant. For others, it showcases future possibilities, but cloud-based chatbots remain more accessible.
