Improved Plasma X11 experience

This guide is to improve the KDE Plasma experience on X11. It particularly applies to those using the modesetting driver (mainly Intel graphics cards)

Install Xorg-git or Xlibre

This is a crucial step. XLibre and xorg-git contain the "TearFree" feature for modesetting, which is not available in the standard releases. If you use a driver other than modesetting, check that the TearFree option exists for your driver.

Installation depends on the distribution you use. On Arch Linux and derivatives:

Xorg-git:

Survey of available implementations for using Gemma 3n on local devices.

In the pursue to make an impactful app that uses Gemma 3n model, recently published by Google, I have been looking for available implementations for using Gemma 3n on local consumer devices, such as your regular iPhone and Android phones, maybe macOS and even Windows-based laptops.

Gemma 3n is a multi-modal model that can process text, images, and audio. See overview https://ai.google.dev/gemma/docs/gemma-3n

This is a very beginning of hackathon, so the open-source implementations available today are limited to those that google pushed to the public just days before the release. The vest survey so far was published on Hugging Face, see https://huggingface.co/blog/gemma3n

It says "Gemma 3n fully available in the open-source ecosystem", but definition of "fully" is blurry as the multi-modal context is very complicated topic and the designs of some ecosystem toolings are not even ready to accept such "multi" context to begin with. Le

Atlant announces 1.0.0-rc2 node release

This is a bugfix release that resolves node performance issues and adds new supported platforms.

DB growth issue

The major bug that is closed within this release was about internal state DB growth. For our key-value store we use a 3rd-party component called BadgerDB (https://github.com/dgraph-io/badger/) and at the moment of our initial release it had a flaw, that wasn't properly documented. Since our release they improved that part in their codebase and added guidelines in the documentation, we followed these guidelines and now the issue is closed.

The issue with DB growth had the most effect on our testnet nodes, some of them became unresponsive and failed to sync with new clients. We strongly recommend anyone who tested the node to update the executable and restart the sync.
