Good morning and welcome, everyone! I'm Dimitri Bellini, and you're here again with me on Quadrata, my channel dedicated to the world of open source and IT. This week, we're diving into something new and exciting: a truly noteworthy tool that can help you in very specific situations.

We're going to talk about Pangolin VPN, and its promise is right in the name: "Zero Open Ports." While the concept of a secure tunnel isn't new, Pangolin offers a unique, simplified approach. It's an open-source, self-hosted solution that lets you create a reverse tunnel to your internal servers, all managed through a centralized, user-friendly platform. Let's explore what makes it so special.

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. I know I've been away for a few weeks—I managed to get a bit of a vacation in—and I've come back with a ton of ideas for new open-source software to share with you.

But today, I want to take a step back and have a more general chat. This is for anyone who works in a company that has to deal with much larger enterprise clients, or for anyone involved in the high-stakes decision of choosing which software to invest in. In the world of IT, there's a powerful and often mysterious force that guides these decisions: the Gartner Magic Quadrant.

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:

This week, we're diving back into the world of open-source solutions. I stumbled upon a truly stunning tool in the file-sharing space that has a wonderful nostalgic feel, reminiscent of the BBS days of the 90s. It's called Copyparty, and its charm lies not just in its retro vibe but in its incredible versatility. You can install it almost anywhere, making it a fantastic utility to have in your toolkit.
