This downloads standalone MSVC compiler, linker & other tools, also headers/libraries from Windows SDK into portable folder, without installing Visual Studio. Has bare minimum components - no UWP/Store/WindowsRT stuff, just files & tools for native desktop app development.

Run py.exe portable-msvc.py and it will download output into msvc folder. By default it will download latest available MSVC & Windows SDK - currently v14.40.33807 and v10.0.26100.0.

You can list available versions with py.exe portable-msvc.py --show-versions and then pass versions you want with --msvc-version and --sdk-version arguments.

To use cl.exe/link.exe first run setup_TARGET.bat - after that PATH/INCLUDE/LIB env variables will be updated to use all the tools as usual. You can also use clang-cl.exe with these includes & libraries.

To use clang-cl.exe without running setup.bat, pass extra /winsysroot msvc argument (msvc is folder name where output is stored).

CUSTOM GAME ENGINES: A Small Study

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.

Nowadays lots of companies choose engines like Unreal or Unity for their games (or that's what lot of people think) because d

> ¿Cómo cambio el tamaño de las fonts?

En DemoWindow > Configuration > Fonts :

• Para cambiar el tamaño de la font de una sola ventana, existe ImGui::SetWindowFontScale(window_scale), donde window_scale es un float que va desde 0.0 (tamaño casi invisible) a 2.0 (tamaño doble que el normal).
• Para cambiar el tamaño de una font en todas las ventanas, alcanza con modificar io.FontGlobalScale. io es el contexto de ImGui que se obtiene en la inicialización. FontGlobalScale es un float que va desde 0.0 (tamaño casi invisible) a 2.0 (tamaño doble que el normal).

Computational Fluid Dynamics (in graphics mostly)

Disclaimer: I have no professional education in Compulational Fluid Dynamics, these are various notes on what I found/learned when trying to learn a bit on the topic. Some of the notes lack sources as I wrote them up later often just remembering some StackExchange answer. Some things I might have misinterpreted.

You should not use the Open SSH client that comes with Git for Windows. Instead, Windows 10 has its own implementation of Open SSH that is integrated with the system. To achieve this:

1. Start the ssh-agent from Windows Services:

• Type Services in the Start Menu or Win+R and then type services.msc to launch the Services window;
• Find the OpenSSH Authentication Agent in the list and double click on it;
• In the OpenSSH Authentication Agent Properties window that appears, choose Automatic from the Startup type: dropdown and click Start from Service status:. Make sure it now says Service status: Running.

2. Configure Git to use the Windows 10 implementation of OpenSSH by issuing the following command in Powershell:

git config --global core.sshCommand C:/Windows/System32/OpenSSH/ssh.exe
