Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.

Vim without NERD tree or CtrlP

I used to use NERD tree for quite a while, then switched to CtrlP for something a little more lightweight. My setup now includes zero file browser or tree view, and instead uses native Vim fuzzy search and auto-directory switching.

Fuzzy Search

There is a super sweet feature in Vim whereby you can fuzzy find your files using **/*, e.g.:

:vs **/*<partial file name><Tab>

Rich Already Answered That!

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.

Table of Content

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Follow the dirty money

A shady Internet business has been discovered.

The website has been made public by a whistle blower. We have enough evidence about the dirty deals they did. But to charge them we need to get hands on precise numbers about the transactions that happened on their platform.

Unfortunately no record of the transactions could be seized so far. The only hint we have is this one transaction:

	// I had to write this code in just a few minutes to get it ready while my article was still trending.
	// I decided to exclude anyone not on desktop Chrome to avoid spending time on browser issues.
	// Here I am trying to test if the user is on desktop Chrome.

	function onDesktopChrome() {
	var pattern = /Android\|webOS\|iPhone\|iPad\|iPod\|BlackBerry\|IEMobile\|Opera Mini\|Mobile\|mobile\|CriOS/i;
	var isMobile = pattern.test(navigator.userAgent);
	if (isMobile) {
	return false;
	} else {

	// Faster solution for:
	// http://www.boyter.org/2017/03/golang-solution-faster-equivalent-java-solution/
	// With threading.
	// g++ -std=c++11 -Wall -Wextra -O3 -pthread

	// On my computer (i5-6600K 3.50 GHz 4 cores), takes about ~160 ms after the CPU
	// has warmed up, or ~80 ms if the CPU is cold (due to Turbo Boost).

	// How it works: Start by generating a list of losing states -- states where the
	// game can end in one turn. Generate a new list of states by running the game

	package main

	import (
	"context"
	"log"
	"net/http"
	"os"
	"os/signal"
	"time"
	)
