One of the most critical gaps in traditional Large Language Models (LLMs) is that they rely on static knowledge already contained within them. Basically, they might be very good at understanding and responding to prompts, but they often fall short in providing current or highly specific information. This is where RAG comes in; RAG addresses these critical gaps in traditional LLMs by incorporating current and new information that serves as a reliable source of truth for these models.

Security logs are the quiet sentinels of your Linux systems, recording critical information that can mean the difference between detecting an intrusion and discovering a breach months too late. For most DevOps professionals and system administrators, these logs contain valuable insights that often go untapped. While they're essential for compliance, their real value lies in providing visibility into your system's security posture and operational health.

Troubleshooting failed cron jobs without proper logging can be frustrating. Ubuntu cron logs record the execution of scheduled tasks, helping you identify what's working and what isn't. This guide covers what engineers need to know about Ubuntu cron logs – from finding them to analyzing their contents and setting up effective monitoring solutions.

I’ve written about the EU Cyber Resilience Act (CRA) on our Canonical blog a few times now, and I think now’s the perfect time to talk about the implications of this new regulation and what it means for IoT and device manufacturers on the practical level of how they design and build Products with Digital Elements (PDEs).

Running Ubuntu servers without proper monitoring can lead to unexpected issues. For DevOps engineers and SREs, effective tracking is crucial for maintaining system health and performance. This guide covers everything you need to know about monitoring Ubuntu servers, from the basics to advanced strategies, helping you keep your systems running smoothly, whether you manage a single server or a large fleet.

In our previous article, we outlined what a Linux coredump is and how they work under the hood. One common constraint we see in embedded Linux, however, is a limited amount of storage space. Whether we’re trying to limit writes to disk, or need to reserve most of the disk space available to a device for other data, sometimes we just don’t have enough space to store coredumps.

Time is running out to be in full compliance with the EU Cyber Resilience Act, and we’re helping developers and manufacturers understand how to do just that. Here’s what we’ve been up to since March in helping the wider community understand how to meet the CRA head-on.
