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

Debugging PHP with XDebug v3 inside Docker using VSCode

Assumptions / Prerequisites

XDebug v3+ inside Docker (e.g. php:7.3-apache Docker image)
Running Docker v20.10+
VSCode with PHP Debug Extension (Felix Becker)
Using Docker Compose for orchestration

Objective

In some cases, only these lines will work

for product in IntelliJIdea WebStorm DataGrip PhpStorm CLion PyCharm GoLand RubyMine; do
    rm -rf ~/.config/$product*/eval 2> /dev/null
    rm -rf ~/.config/JetBrains/$product*/eval 2> /dev/null
done

But if not, try these

UPDATE: I have baked the ideas in this file inside a Python CLI tool called pyds-cli. Please find it here: https://github.com/ericmjl/pyds-cli

How to organize your Python data science project

Having done a number of data projects over the years, and having seen a number of them up on GitHub, I've come to see that there's a wide range in terms of how "readable" a project is. I'd like to share some practices that I have come to adopt in my projects, which I hope will bring some organization to your projects.

Disclaimer: I'm hoping nobody takes this to be "the definitive guide" to organizing a data project; rather, I hope you, the reader, find useful tips that you can adapt to your own projects.

Disclaimer 2: What I’m writing below is primarily geared towards Python language users. Some ideas may be transferable to other languages; others may not be so. Please feel free to remix whatever you see here!

background: 使用 fly.io 的日本机器安装 cloudflare tunnel 利用它代理部署了 edgetunnel 的 cloudflare worker 的域名实现指定使用日本的IP地址。

同时也可以通过使用指定中转IP 实现使用全球任意地区的cloudflare IP

	#
	# In fractal geometry, the Minkowski–Bouligand dimension, also known as
	# Minkowski dimension or box-counting dimension, is a way of determining the
	# fractal dimension of a set S in a Euclidean space Rn, or more generally in a
	# metric space (X, d).
