ELF Format Cheatsheet

Introduction

Executable and Linkable Format (ELF), is the default binary format on Linux-based systems.

Compilation

Go - The Ultimate Folder Structure

Organizing your Go (Golang) project's folder structure can help improve code readability, maintainability, and scalability. While there is no one-size-fits-all structure, here's a common folder structure for a Go project:

project-root/
    ├── cmd/
    │   ├── your-app-name/
    │   │   ├── main.go         # Application entry point
    │   │   └── ...             # Other application-specific files

Dapr Error Handling/Codes

Problem

Across Dapr errors are surfaced for different conditions, without consistent messages, details of the error, standard formats, and no clear indication of what/where the error initiated.

This makes troubleshooting and debugging quite difficult and requires a deep understanding of the parts of Dapr and how those parts interact with each other.

To help with the issues raised above, it would be ideal if a solution could provide:

Greater details of errors that occured.

	# Script for Ubuntu: Nvidia Multi-GPU Installation and Testing (Adaptable for other distros)

	# Step 0: Clean Nvidia Installation
	# If you need to completely remove a previous Nvidia installation, use these commands.
	# This ensures that you start with a clean slate for a new installation.
	sudo apt-get --purge remove "nvidia"
	sudo apt-get --purge remove "cuda" "cudnn" "cublas" "cufft" "cufile" "curand" "cusolver" "cusparse" "gds-tools" "npp" "nvjpeg" "nsight" "nvvm" "libnccl*"

	# Verify that the removal is complete by checking if any Nvidia, CUDA, or cuDNN packages are still installed.
	apt list --installed \| grep cuda
