The default port for SSH is 22, and if ..

What is LVM (Logical Volume Management)? LVM is a form of storage virtualization that offers system admins a more flexible approach to managing disk storage space.

You can do this on both Unix and Windows; but this time, I'm running it on windows. ssh-keygen is a utility that generates a key pair - public and private key. ssh..

CUDA (Compute Unified Device Architecture) is a parallel computing platform and application programming interface (API) model created by NVIDIA. IT enables CUDA-enabled graphics processing unit for general-purpose preprocessing. It extended the capabilities of the GPU to handle computational workloads beyond graphic. Key Features: Parallel Computing: CUDA enables running thousands of threads con..

Since we have our project folders ready, it's time to set it up. This includes adding urlpatterns in urls.py, and altering the settings.py and view.py files. The most basic setup is the urlpatterns named index in our root folder from our app folder. urlpatterns = [ path('', views.index, name='index') ] This sets up the first pattern matches the root URL ('') and maps it to the index view functio..

Since we somewhat have the backend code ready to go, we choose a framework to start developing a web applicaiton.
