Switching to landscape in LaTeX

I have to write a project proposal using LaTeX, which is pretty new for me. I've been doing good so far, but I now need to include a Gantt-diagram inside the proposal and, as the image with the diagram is horizontal, I'd like to turn the Page which includes to diagram to be in landscape mode. What can I use to achieve this?

Problem installing docker on windows 10

I've just tried installing docker on my windows pc, however after the installation, my monitors are not able to work properly anymore. Normally I use 2 monitors that extend each other so I can use both at the same time. After the installtion of docker they started to just duplicate and also had issues with the resolution. When I remove docker and disable hyper-v the problems stop, I do need to use docker however for a current project, so I need to find a workaround to solve these issues. I am using a Lenovo Y50-70 notebook.

How to use data objects in BPMN?

Styling in React

I have an existing React project, a multi-page application that is now quite large. My biggest weakness is the styling, I have never taken the time to learn it properly and my customers won't accept my work even if the functions are great but the layout is terrible. What are my options?

Decision tree algorithm for categorical data

to understand better how a decision tree works, I was trying to write my own code for the ID3 algorithm. What I however found out, is that the ID3 algorithm only states how to evaluate each possible split of data in each node and choose the best split. After playing with it for some time, I found out that the basic algorithm works fine only for small instances of data as in every step it needs to try all the possible splitting points the dataset allows.

multiple dockerfiles for one code

I have a python application that I need to put into a docker. Since I need the docker to be able to run on windows servers and linux servers, its best to create two separate docker images, one for each operating system. Since docker is composed using docker files, and each docker image is a derivation of prebuilt docker images and they are already build with different operating systems in them, I need to have different docker files for each pipeline. However, docker does not allow to have multiple docker files and only allows one docker file named "Dockerfile" in a folder with code.
