Hi there, At the beginning of the month I didn’t think to make that much progress. But now I get the feeling that the GUI client could come to an end next month. Why do I have this feeling? It’s looking really good already, not gonna lie. So as stated in my last update in January, loading older messages needs to be implemented as well as switching accounts during runtime. Now it is. Getting older messages still needs some tweaking to not load all older messages but it’s good enough for now. image of messenger-gtk account selection Switching accounts was more difficult to implement because I had to go back looking into the Messenger service of GNUnet itself, fixing that the service will run as user to make use of the same EGOs as the client side library in multi-user setups. The client side library ( libgnunetchat ) now exposes each of your EGOs as account with name and own directory to store the files and configurations used by the applications. Another benefit of this is tha...

During the lat weeks I implemented with a few other students at university a simulation for soft-body dynamics and really basic fluids using the material point method (in short MPM ). The goal was to use different sizes for individual particles which would decrease or increase their specific area of impact. It pretty much works like this: 👉 1. You have an amount of particles which you spread around to represent a specific volume (for example a sphere or a cube but it could be any mesh really). Then you give each particle a mass, velocity, position and volume. The particles will pass in their area of impact their information about mass and velocity into a grid data structure as weighted impulse and weighted mass depending on the distance between each grid cell and your particle. 👉 2. The next step is to adjust forces to the grid cells and collect data in the area of impact of each particle from cell back to the particle. Then you calculate from that the new velocity of the particl...
