Good morning everyone! Dimitri Bellini here, and welcome back to Quadrata, my channel dedicated to the world of open source and all the IT that I, and hopefully you, find fascinating.

This week, we're diving into a powerful solution that addresses a common and persistent challenge in IT management: the lack of a single, reliable source of information. In large infrastructures, it's often difficult to know what objects exist, where they are, what their relationships are, and how to even begin monitoring them. Many turn to a Configuration Management Database (CMDB), but keeping it manually updated is a struggle. What if we could automate this process?

Good morning everyone, Dimitri Bellini here! It’s great to be back with you on Quadrata, my channel dedicated to the world of open source and IT. It’s been a little while since my last video, as I’ve been quite busy traveling between the Zabbix Summit in Riga and Gitex in Dubai. The energy at the Summit was incredible, and I returned not just with great memories but with a clear vision of the future of monitoring. And today, I want to share that vision with you.

So, grab a coffee, and let’s dive into a recap of the fantastic Zabbix Summit and, more importantly, the groundbreaking features coming in the next major release: Zabbix 8.0 LTS.

Good morning, everyone! Dimitri Bellini here, back on my channel, Quadrata, where we explore the fascinating world of open source and IT. If you've been following along, you know we've spent a lot of time diving into Large Language Models (LLMs) for tasks like summarizing topics and answering questions. But today, we're venturing into a different, more visual side of artificial intelligence: the creation of images.

We're going to explore a powerful, node-based graphical interface called ComfyUI. This open-source tool allows you to build sophisticated workflows for generating AI images using Stable Diffusion models. Forget complex code; we're talking about a visual playground for your creativity.

Good morning and welcome, everyone! It's Dimitri Bellini, back again on Quadrata, my channel dedicated to the open-source world and the IT that I love. It’s been a little while since we talked about our good friend Zabbix, and I’m excited to share something I stumbled upon that I think you're going to love.

While browsing the Zabbix support portal, I came across a community member, Ryan Eberle, who has developed an incredible set of custom widgets. His GitHub repository is a goldmine of enhancements that bring a whole new level of functionality and clarity to our Zabbix dashboards. These aren't just minor tweaks; they are game-changing improvements that address many of the limitations we've all faced.

Good morning, everyone! Dimitri Bellini here, and welcome back to Quadrata. For a while now, I've been waiting for something genuinely new to discuss in the world of artificial intelligence. The on-premise, open-source scene has been buzzing, but largely dominated by excellent models from the East. I was waiting for a major American player to make a move, and finally, the moment has arrived. OpenAI, the minds behind ChatGPT, have released not one, but two completely open-source models. This is a big deal, and in this post, I’m going to break down what they are, what they can do, and put them to the test myself.

OpenAI has released two "open-weight" models, which means we have access to the model's core infrastructure and the data it was trained on. This is fantastic news for developers, researchers, and hobbyists like us, as it allows for deep customization. The two new models are:
