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

Batch-Resize Images(Linux)

Keeps aspect ratio find . -iname '*.png' -exec convert \{} -verbose -set filename:base "%[basename]" -resize 64x64 "./64x64/%[filename:base].png" \;`` Forces size: find . -iname '*.png' -exec convert \{} -verbose -set filename:base "%[basename]" -resize "64x64!" "./64x64/%[filename:base].png&

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

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

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
