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

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:

qt-creator

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

EnTT-(de)serialization with nlohmann::json

Again playing with EnTT (ECS) which has a builtin mechanism that helps you (de)serialize a registry. You have to implement an 'archive' that (de)serializes the data. Here in the source-code I use nlohmann::json for this. In the end it was simpler than it seemed at

zproject(part3): generate bindings

After part1(getting started) and part2(looking at generated code) now its time to generate bindings, but before that let's generate a Docker-Image that will create a docker-image with this lib installed. Generating additional files on the project-data you can add targets. There are multiple targets to choose

zproject(part 2): the generated files

In the first part we saw how to create and build a zproject and in this part we will have a look at the code that is actually generated and add some methods to our class using an corresponding api-file. include/shouter.h: /* ========================================================================= shouter - class description Copyright (c) the

zproject(part1): getting started

ZProject is a project skeleton generator that helps you create c-APIs and generate multiple build-targets(cmake,autotools,..) with multiple scripting-language-bindings(python,lua,...) . The single source of truth is that project.xml-File that controls what flows will run. The whole workflow is based on the GSL-Templating/Scripting-Tool. Disclaimer: I just started

ghost cms: get code highlighting to work

If you have (like me) problems to get code-highlighting to work, here is my setup that works good enough for me. I actually use the first 'prism'-way but also added a 'highlight.js'-way. Go to the backend > code injection: Prism: header: <link

use nlohmann::json for serialization

Here some samples of how to use nlohmann::json for (de)serialization Define a struct following macro in it: NLOHMANN_DEFINE_TYPE_INTRUSIVE(Struct-name, member1, member2,...) This will add everything needed for nlohmann::json to (de)serialize this struct. struct Tower{ std::string name; int type_id; float range; NLOHMANN_

I attended this years (online) global game jam('Headup Remote Jam 2021'). As always I want to use this weekend to kick myself in the butt to finish something in a solo-project. My setup was Urho3D, Blender using my Urho3D-Blender-Integration. The blender integration basically worked quite well, even

Mate Linux: alt+tab problems

Lately I experienced problems using alt+tab for switching between applications in manjaro-linux using mate-desktop. The problem seems to be the little thumbsnails showing a current preview of the specific application.
