AI agents and MCPs beauty

Radu Marias — Wed, 24 Sep 2025 11:43:47 +0000

After playing a bit with AI agents like Claude Code, Codex, Gemini-cli, warp terminal (warp. dev), and MCP, I feel that:

LLMs are the brain (but alone, they cannot interact with the outside world)
MCP servers are the tools (that help the brain interact with the world)
Agents are the hands (that link the brain with the tools)

P.S.

Don't get me wrong, I don't think we're there, just yet, that AI is even remotely close to replacing us (although in some aspects it is), or agree with this hype on AI, where people are giving it way too much credit.

However, it's wise to use it for what it's good at, but not to have absurd expectations when it's not yet good enough.
Because it's here to stay, just like the Internet, and it can significantly enhance us.

And we should not forget:
"It is not the strongest of the species that survives,
not the most intelligent that survives.
It is the one that is the most adaptable to change."

Humans are best at (compared to other animals):

making tools
collaboration The internet and its services are the best collaboration medium, and AI models are the most effective tools.

FOSE (Free and Open Source Education)

Radu Marias — Fri, 27 Dec 2024 06:31:14 +0000

Information used for education, and access to it, should be free and publicly available, just like sunlight, air, and rainwater

If you want to make money from education, teach and help people to learn, and sell that, but using free and publicly available information

Join our engaging community exploring the rise of AI agents! Let’s dive into the technical aspects and brainstorm creative ideas together. We’d love to have you on board! https://t.me/+QQNb3paneEg5NTM8

Idea: Make Apache Flight (gRPC) work over HTTP/3 (QUIC) and make use of RDMA (fast memory transfer). All made in Rust

How to build a virtualized GPU that executes remotely and keeping your data local?

Radu Marias — Fri, 23 Aug 2024 13:28:59 +0000

The idea is to build something like this:

Virtualization for GPU that allows you to run local GPU apps and the code is actually run in the cloud, keeping your data local.

Functionality:

vGPU is a virtualization layer for a GPU
your local app "runs" on local vGPU
local app decrypts the actual local data and sends the (CUDA) instructions to the remote GPU-Coortinator
GPU-Coortinator distribute the instructions to multiple real GPUs
then it sends the results back to vGPU which sends them to the local app

The advantage is your private data never leaves your network in plain. Only actual GPU instructions (CUDA instructions) are sent over the wire but encrypted with TLS.

I know it will be slow, but in cases where the data flow is small compared to processing time it could be a reasonable compromise for the security it gives you.

Also because instructions are distributed to multiple GPUs, when possible, it could offer better performance, in some cases, than locally
