I would really like to play with some LLMs locally, because it will allow to better understand the nuances of their work. It’s like getting acquainted with AWS without having dealt with at least VirtualBox before – working with the AWS Console or AWS API will not give an understanding of what is happening under… Read More »
In the previous article, we figured out what an MCP is in general, and created a basic MCP server that was connected to Windsurf – see AI: What is the MCP? Now, let’s try to create something more useful, for example, an MCP server that will connect to VictoriaLogs and receive some data. In fact,… Read More »
Everyone around us is talking about MCPs all the time, and it’s time to understand the topic. So, today we will deal with the basic concepts – “what it is in general”, then we will write our own “micro-MCP server”, and in the next post – something more real, about working with VictoriaLogs. LLM Limitations… Read More »
To put it very simply, Celery is something we can use to perform tasks outside of our main service. For example, there is a Backend API that has some kind of endpoint to which mobile devices send information that the user has created a new whatever in the application. The task of the Backend is… Read More »

I need to migrate the data from the old VMSingle Pod to the new one on the new cluster, and to do this, I need to find VMSingle’s data on an EC2. Note: regarding the migration… Read More »

We’ll do it as usual: first run manually locally on… Read More »
In Kubernetes, we run GitHub Runner for the build and deploy of our Backend API, see GitHub Actions: Running Actions Runner Controller in Kubernetes. But over time, we noticed that there was too much traffic on the NAT Gateway – see VictoriaLogs: a Grafana dashboard for AWS VPC Flow Logs – migrating from Grafana Loki.… Read More »
It’s not often, but sometimes I need to boot the system from a USB and rebuild initramfs-linux.img. This post is more of a quick note to myself on how, what, and where to mount on my laptop to run mkinitcpio, as I have LVM partitions, separate disk partitions for /boot, and swap. iwctl and WiFi… Read More »
I have already mentioned the EXPLAIN feature in the PostgreSQL: AWS RDS Performance and monitoring blog post, but this is such an interesting and useful thing that it’s worth talking about it separately. In addition, AWS RDS for PostgreSQL has the ability to enable Execution Plans logging with EXPLAIN, which is also useful for… Read More »
