October/November in KDE Itinerary

Since the last summary KDE Itinerary has been moving with big steps towards the upcoming 21.12 release, with work on individual transport modes, more convenient ticket access, trip editing, a new health certificate UI, better transfer handling and many more improvements.

New Features
Current ticket access A small but very convenient new addition is the “Current ticket” action, which immediately navigates you to the details page of the most current element on the itinerary. That comes in handy when having to show or scan your ticket and avoids having to find the right entry in the list in a rush. This action is now also accessible from jump list actions in the taskbar on Linux, or app shortcuts on Android.

These days, it’s quite common to see people carrying their data around at all times. Different devices and technologies are used for this purpose, including a certain device called USB (Universal Serial Bus).

Godot Engine - Multiplayer in Godot 4.0: Scene Replication (part 1)

It's finally time for the long-awaited post about the new multiplayer replication system that is being developed for Godot 4.0. Below, we will introduce the concepts around which it was designed, the currently implemented prototype, and planned changes to make it more powerful and user-friendly.

Design goals
Making multiplayer games has historically been a complex task, requiring ad-hoc optimizations and game-specific solutions. Still, two main concepts are almost ubiquitous in multiplayer games: some form of messaging, and some form of state replication (synchronization and reconciliation). While Godot does provide a system for messaging (i.e. RPC), it does not provide a common system for replication. In this sense, we had quite a few #networking meetings in August 2021 to design a replication API that could be used for the common cases, while being extensible via plugins or custom code. Read more
