Introduction

My First “Big” Interview
- Explain the problem
  
  讲了个故事，第一次重要面试，题目是在 1000 个文件中找出特定字符串，使用 java 写了 40 分钟，实际可以用grep完成~~
- The length of knowledge is a measurement of its value
What is developer Productivity?
- Definition: All the things that separate you from working

Ansible

The Problem Statement

I have new computer(not a problem) and I want zsh installed(the problem)

1	sudo apt install zsh

1 2	# The thing we forget to do chsh -s `which zsh` # when typing this I did chsh zsh

Please don’t make fun of me. oh-my-zsh does give you a -1 BTW

1	curl -L https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh \| sh

Add autosuggest to the plugins

plugins=(git zsh-autosuggestions)

git clone https://github.com/zsh-users/zsh-autosuggestions.git ~/.oh-my-zsh/plugins/zsh-autosuggestions

Ansible Overview

The problem statement
- I have a new computer(it is the problem)
- Installing the things I need

ANSIBLE!!

Docs
Isn’t that a cloud configuration thing?? Something like Koobernetes
Let’s talk about the anatomy of ansible
Top level

- hosts: localhost
  become: true
  pre_tasks: ...
  vars: ...
  tasks: ...

Task

- name: string
  _SOME_ACTION_
  tags:
    - list
    - of
    - tags

Creating Ansible Tasks to Install zsh

Let’s create the zsh install but with ansible

GUN Stow

1	brew install stow

YADM & Setup Tools Review

YADM

Terminals

What is a window manager?

My theory on navigation

i3 for ubuntu (very disorienting the first time)

1	sudo apt install i3

Yabai for mac
bug.n for windows

Shell

The difference between shell and terminal

Terminal just take input and output the result
Shell is to prevent you doing something wrong break the terminal

OhMyZsh

How to install

1	curl -L https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh \| sh

So what do I get out of oh-my-zsh?

Open up .zshrc and go to lines plugins
Personal Opinion
- Choose something
- Learn about it to some small amount
- Get good at core utils
- Take advantage of already built tools that are amazing.

Terminal & Multiplexing

What do I use?

xterm
tmux

Tmux

Install tmux

1	brew install tmux

Ctrl + d write an EOF(end of file) to the stdin, which closes the shell

Basic tmux Commands

1	tmux list-sessions

1	tmux a # or tmux attach

Terminology

Prefix Key
- The key combo you press(default Ctrl + b)
- Draw it out

Creating sessions

1	tmux kill-server

1	tmux list-sessions

tmux

1	tmux list-sessions

1 2	tmux # error, can't open new tmux server in a tmux server nested tmux new-session # same error

1	tmux new-session -d # with parameter -d, can open a new session in a tmux session

Navigation tip

to the next session <prefix> - (
to the prev session <prefix> - )

Close and create new session

1 2	tmux kill-server tmux new-session # equivalent to tmux

Windows & Sessions Management with tmux

1
2
3

ctrl + b d # detached session

tmux a # reattach the session

Navigation tip

You can see all of the sessions and their windows by pressing <prefix> + w

Create a bunch of windows

That way we can really see what happened there. For you to do this on your own use detach in conjunction with tmux new-session command

Fun fact, Ctrl - d vs prefix - d

Ctrl + d = EOF
prefix + d = tmux detach

So those are sessions

It may be hard to see the difference between a session, a window, and a pane

Creating Windows

1 2	tmux tmux new-window

this is equivalent to <prefix> + c

Navigation tip

<prefix> + n for next window
<prefix> + p for prev window
<prefix> + # for the # window

You can name sessions and windows

1	tmux new-session -d -s "foo"

1	tmux new-window -n "foooo"

Usability tip

You can’t have sessions with the same tip

There are panes

You can definitely look into panes to be able to split your view.
- <prefix> + % split window in half horizontal ctrl + d to close the pane

Directories with tmux

Taking tmux to the next level

We know some tmux commands

1	tmux new-session -s 'foobar' -d

BUT DID YOU KNOW?

tmux new-session -s 'foobar' -d -c '$HOME/personal/develop'

tmux new-window -n 'foobar' -c '$HOME/personal'

tmux switch-client -t 'foobar'

We can specify a command

1	tmux new-window -n 'foobar' [some command goes here]

man tmux

CLI Piping

Quick intro into CLI piping

1	prog1 \| prog2 \| prog3

Bash

fzf

We have one more thing to learn

1	brew install fzf

fzf

create a new file name tmux-sessionizer

1 2	#!/usr/bin/env bash find ~ -mindepth 1 -maxdepth 1 -type d \| fzf

#!/usr/bin/env bash
session=$(find ~ -mindepth 1 -maxdepth 1 -type d | fzf)
session_name=$(basename "$session" | tr . _)

if ! tmux has-session -t "$session_name"; then
  tmux new-session -s "$session_name" -c "$session" -d
fi

tmux switch-client -t "$session_name"

Steaming hot Navigation Tip

<prefix> + L go to previous session

But how do I make this easy to use?

We can use zsh to bindkey
We can use tmux to bindkey
Make it available in your path
call out from vim

We also need to store in a place that we don’t lose… Where could that be?

Cheat Sheet

Take it to the next level

Common problem we face as developers?

What’s that splice interface to an array in JavaScript?
How do I tokenize a string in C?
How do I create a class in cpp?
What’s the syntax for an enum in TypeScript?

curl cht.sh/find~exec

curl cht.sh/javascript/splice+array

curl cht.sh/typescript/enum

Learning

1
2
3

curl cht.sh/golang/:learn

curl cht.sh/golang/:learn+slice

Creating the Cheat Sheet Script

We have the knowledge this time, let’ build it

#!/usr/bin/env bash
languages=$(echo "golang c cpp typescript rust js" | tr " " "\n")
core_utils=$(echo "find xargs sed awk" | tr " " "\n")
selected=$(echo -e "$languages\n$core_utils" | fzf)

read -p "GIVE A QUERY: " query

if echo "$languages" | grep -qs $selected; then
  tmux split-window -h bash -c "curl cht.sh/$selected/$(echo "$query" | tr " " "+") | less"
else
  tmux split-window -h bash -c " curl cht.sh/$selected~$query | less"
fi

tmux Plugins & RC

How I link it up!

1	bind-key -r i run-shell "tmux neww tmux-cht.sh"

TmuxRC

Location will be $HOME/.tmux.conf

Tools

Tools: Git worktrees

git-worktree documentation

So what is a work tree?

First, checking out maybe a bit different than you are use to. You are going to use the --bare option when checking out.

1	git clone --bare git@github.com:ThePrimeagen/refactoring.nvim.git refactoring.nvim

Notice that I did name my checkout. When using --bare I notice that it always includes the .git in the folder name.

1
2
3

# /refactoring.nvim on git:master o [21:35:23]
HEAD        description info        packed-refs
config      hooks       objects     refs

1 2	$ git status fatal: this operation must be run in a work tree

So what do we have available?

1	git worktree list

1	man git-worktree

The first paragraph gives you the information you need to know, but a way I streamline getting the exact commands to run is using cht.sh

$ curl cht.sh/git~worktree

 tldr:git-update-index
# Pretend that a modified file is unchanged (`git status` will not show this as changed):
git update-index --skip-worktree path/to/modified_file

 tldr:git-worktree
# git worktree
# Manage multiple working trees attached to the same repository.
# More information: <https://git-scm.com/docs/git-worktree>.

# Create a new directory with the specified branch checked out into it:
git worktree add path/to/directory branch

# Create a new directory with a new branch checked out into it:
git worktree add path/to/directory -b new_branch

# List all the working directories attached to this repository:
git worktree list

# Remove a worktree (after deleting worktree directory):
git worktree prune

git log

1	git log -S QUERY #search

Linux Core Utils

What are core utils?

A set of programs that can make your life easier doing ad hoc tasks

1	cat text.file \| xargs \| tr " " "\n" \| sort \| uniq -c \| sort -n

Linux Core Utils & sed Tips

Sum each line and display the max sum

1	echo "5 7 9\n11 13 15" \| tr " " "+" \| bc \| sort -nr \| head -1

Some utils you should just know

cat
read
grep
tr
echo
awk
bc
sort
head
sed
