Recently, Google released the open-source LLM model Gemma 4. Its E2B and E4B variants don't require powerful hardware, perform well in tests, and support tool calling. So let's install it locally and try it as a chatbot, image recognizer, and also connect it to Claude Code with a single command.

Almost 8 months ago, I switched from Kanboard to self-hosted Gitea for managing my personal projects. It's not perfect, has limitations, unusable on mobile, but it fits my needs, so I keep using it.

But recently, I found a cool project called tiki. It's a markdown-based git-versioned documentation and issue management tool. All tasks live in your project directory. Here's why I think you'd love it if you're a fan of terminal user interfaces:

Recently, I tried to set up a network tunnel to access some of my services running on a free-tier Oracle Cloud ARM compute instance. Despite correctly setting the ingress rules and iptables and ufw, there was a problem with opening the UDP port. Then I made a stupid mistake: I routed all the server's traffic through the closed port.

Immediately, my SSH connection was closed. All my running services stopped responding.

Some time ago I decided to move all tasks from Kanboard closer to the projects in my Gitea self-hosted instance. Surprisingly, Gitea doesn't have any importers, so I ended up preparing the data and calling the Gitea API.

With convolution kernel it's possible to implement numerous interesting effects, such as motion blur, sharpening, edge detecting, emboss, etc. These effects we going to explore in this article.
