Caffeine is a software to prevent our Linux from locking the screen and then going to sleep. To do this, we will give it caffeine.

Installation

The installation is very simple, we just have to do

sudo apt update
sudo apt install caffeine

Infinite Caffeine

If we press the windows key on the keyboard and type caffeine-indicator, the option to start the software indicator will appear.

If we run it, a software indicator will appear in the top bar of Ubuntu

If we click on the indicator, a menu will appear.

Now we can click on Activate so that our Ubuntu will have infinite caffeine and never go to sleep.

Caffeine for a Command

One thing that happens to me is that when I train a neural network, I like to keep the model evaluation in view, even if I'm not at the computer. But if that training takes hours, at some point the screensaver activates and you can no longer see the training progress. So to fix this, we have caffeinate, which by doing

`caffeinate` COMMAND

We will make our computer have caffeine and not fall asleep while running the command COMMAND

Tomorrow's Agents: Deciphering the Mysteries of Planning, UX and Memory

AI agents, powered by LLMs, promise to transform applications. But are they simple executors today or future intelligent collaborators? To reach their true potential, we must overcome critical barriers. This talk delves into the three puzzles that will define the next generation of agents: 1. Advanced Planning (The Brain): Today's agents often stumble on complex tasks. We'll explore how, beyond basic function calls, cognitive architectures enable robust plans, anticipation of problems, and deep reasoning. How do we make them think several steps ahead? 2. Revolutionary UX (The Soul): Interacting with an agent cannot be a source of frustration. We'll discuss how to transcend traditional chat toward human-on-the-loop interfaces—collaborative, generative, and accessible UX. How to Design Engaging Experiences? 3. Persistent Memory (The Legacy): An agent that forgets what it's learned is doomed to inefficiency. We'll look at techniques for empowering agents with meaningful memory that goes beyond their history, enabling them to learn and making each interaction smarter. With practical examples, we'll not only understand the magnitude of these challenges, but we'll also take away concrete ideas and a clear vision to help build the agents of tomorrow: smarter, more intuitive, and truly capable. Will you join us on the journey to unravel the next chapter of AI agents?

Use this locally

Hugging Face spaces allow us to run models with very simple demos, but what if the demo breaks? Or if the user deletes it? That's why I've created docker containers with some interesting spaces, to be able to use them locally, whatever happens. In fact, if you click on any project view button, it may take you to a space that doesn't work.
