Difference Between Release Mode and Debug Mode in Unity3D

Disclaimer: This post is 100% generated and only is a companion post for Interfaces vs Direct calls. In the context of Unity3D, Debug Mode and Release Mode primarily affect how your C# code is compiled and run, both in the Editor and in builds, impacting performance, debugging capabilities, and logging

Interfaces vs Direct Calls in C#: What Happens Under the Hood?

As a C# developer, you often face the choice between using interfaces or virtual methods versus direct calls. Maybe you want the flexibility of dependency injection or the ability to override behavior later—you never know, right? I personally use interfaces a lot, but there are some important performance considerations

Docker: find container's docker compose-work folder

Quick-Tip: Ever had the problem that there is a docker container popping up and you don't know where it comes from? docker inspect \ --format='{{ index .Config.Labels "com.docker.compose.project.working_dir" }}' \ <container-name> The result will be the work folder in

My Proxmox and ZFS Struggle: How I Fixed System Hangs and Degraded Pools by Moving to LVM

When I set up my Proxmox server, I used ZFS with M2- and SATA-SSDs because I wanted the benefits of data integrity and advanced features. However, I quickly ran into serious problems: my system would hang, my LXC containers became unresponsive, and IO delays skyrocketed. The zpool status command showed

How to Set Up a Secure Private Docker Registry with HTTPS and a Web UI

Generate SSL Certificates Let's generate a self-signed certificate: mkdir certs openssl req -newkey rsa:4096 -nodes -sha256 -keyout certs/domain.key -x509 -days 365 -out certs/domain.crt Create a Docker Compose File Here’s a minimal docker-compose.yml for a secure registry: version: '3.8'

Testing REST API Calls with VS Code: A Guide to the REST Client Extension

When it comes to testing REST API calls, Visual Studio Code (VS Code) offers a powerful tool in the form of the REST Client extension. This extension allows developers to make HTTP requests directly from their code editor, streamlining the testing process and eliminating the need to switch between different

Spring-Boot: Accessing Properties

If you are using spring-boot and want to access properties from your properties- or yaml-file you can do that like this: package xxx.xxx.security.config; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.context.annotation.Configuration; import lombok.Getter; import lombok.Setter; @Getter @Setter @Configuration @ConfigurationProperties("

Let's do a little bit full(?) stack...

As a game developer, I haven't spent much time exploring how web applications are created nowadays. The last significant contribution I made in this realm was developing a high score server for Wood Games 3D (my very very old Android-Game '2011), which I had to write to

Developing a Retro Zelda-like Game for retro and modern Platforms

I actually never mentioned it publicly, but Wolfgang (dotmos) and me are working on and off (a lot off) on a Zelda-like retro game for retro platforms (and modern ones as well). At the moment, we support a variety of platforms including: * C64 (module using bank switching) * Atari ST * Amiga

Turbo Badger

This post dangled for a while in as draft. I didn't finish the project but still will post it.... Atm I'm developing a small multiplayer 'catch'-game using urho3d and its scene-replication. I never really got used to the inbuilt UI (not sure why

AI: Creating a World Time MCP‑Server and Agent with a Local Ollama LLM (llama3.1:latest) on Linux

As the wold of AI is progressing very fast it is time to dive into it. I love the idea to combine LLMs with tools to execute or create context data. This is a very first approach with a local running LLM. In this tutorial, we’ll build a Linux-based

Linux-Startup: NVIDIA Persistence Daemon

Having problems starting ubuntu-linux looking like this? To make the long story short: * Grub > Advanced Options > Pick the latest kernel in rescue mode * In the rescue-menu: * 1) network * 2) root > login to your root account apt remove --purge nvidia-* ubuntu-drivers autoinstall That solved it for me.

KDE Plasma: Restart taskbar

I recently switched from Mate-Desktop (Ubuntu Mate) to KDE Plasma including Bismuth as tiling Window Manager. Tiling is really a new concept to me and I really have to get used to it. But I do like it so far. But... from time to time my KDE Taskbar is disappearing

C: Get reference to parent struct from within nested struct

That title sound a bit confusing so here an example: typedef struct { int x; int y; } point; typedef struct { int width; int height; point topLeft; } rectangle; Taking this example: If you got a pointer on a point-struct 'topleft' but don't know about the struct that contains

Gameboy Advance Setup

retro-platform-jam 5 is about to start and I think I will give GameBoyAdvanced a try. Not sure I will finish something due to the RoomGame and the NetworkGame need some love. But I could use it to write a new renderer for RoomGame. Ok, enough blabla. Here how to setup

Here a video of my beloved game made for 'retro gamejam': PS: Downloads via itch.io

C# Memory-Alignment

EDIT: You can ignore most of the stuff written here. Rule of thumb. Classes will out of the box arrange the data-structures as good as possible, structs build their data-structure (JIT-wise) as the code tells if not [StructLayout(LayoutKind.Auto)] is set. The rest of the text might still be

dotnet publish: specify RuntimeIdentifier

Ever came across this error on publishing a dotnet project that includes libs of your own: error NETSDK1097: It is not supported to publish an application to a single-file without specifying a RuntimeIdentifier. You must either specify a RuntimeIdentifier or set PublishSingleFile to false. E.g. using urho.net with

Build Urho3D for special chipset

I had the problem that I tried to run urho3d-headless on our server for a small game-instance-server-test but got some 'illegal chipset' core dump-mayham. Our server is quite of age. Good that Urho has some options for this out of the box. There is a cmake-option: URHO3D_DEPLOYMENT_

Visual Studio Code: c# omnisharp crashing

Quick tip: If you are using c# in vs code and for some reason the c# language server omnisharp crashes (e.g. you are running/debugging test-cases (in my case xunit)) fastest way to get going again (also with Test to be triggered from within the editor, just restarting omnisharp

git: fixing lfs push looping with error 413

Just stumpled over a problem that I wanted to push a large file (400+mb) as part of a commit into our remote-repository but git ended up continuosly pushing 400+mb and then starting over without any progress. The long story short without knowing what why this fixes the problem:

qtCreator: debugging not working anymore?

All of a sudden (I guess after upgrading lots of libs in archlinux) qtCreator's (at the moment 4.15) debugging stopped working. I tested with gdb manually. Symbols were there and everything looked(!) fine. BUT not a single breakpoint was hit, and manully breaking ended up in the
