omikuji app

swiftではarcNrandom_uniform(UInt32(hoge.count))でランダムに数値を生成します。

Tips
command + option + 0: utility 非表示
launch screen -> main.storyboardに変更可能

tips
command + 0 ->navigator area削除
auto size, auto layout on
story board -> assistant editor -> preview
upgrade frames ->制約に自動調整, items new constrainsで作成時につけることも可能
clear constrains ->制約を解除

上下左右幅いっぱいにするには　margin 0
screen-shot-2016-11-25-at-11-15-42
constrain: Editor -> pin -> height or width
view ctrl + dragでも可能
viewを2つ選択して equal height
multiplier: 2つのviewの比率を設定
screen-shot-2016-11-25-at-11-28-09

labelなどのtextはxcode側でサイズを自動計算するので、必ずしも指定しなくてOK
content Hugging priority 大きくなりにくさ

deviceごとに表示を変えるには、画面下のsize classで設定

Video Player

名言は配列で持たせて、Math.floor(Math.random() * quotes.length)で表示。background-colorは、classを、ipc通信でindex.js, index.html, setting.html間をやりとりしています。また、初期値は、webstorageから値を取得することで、ipc通信を省略しています。

Serverspec init

サーバーテストツール
http://serverspec.org/resource_types.html

With Serverspec, you can write RSpec tests for checking your servers are configured correctly.
Serverspec tests your servers’ actual state by executing command locally, via SSH, via WinRM, via Docker API and so on. So you don’t need to install any agent softwares on your servers and can use any configuration management tools, Puppet, Ansible, CFEngine, Itamae and so on.

tmux commands

Video Player

tmux is a terminal multiplexer
What is a terminal multiplexer? It lets you switch easily between several programs in one terminal, detach them (they keep running in the background) and reattach them to a different terminal. And do a lot more. 

[vagrant@localhost ~]$ sudo yum -y install tmux
インストール:
  tmux.x86_64 0:1.6-3.el6
完了しました!

tmuxの起動

[vagrant@localhost ~]$ tmux new -s ProjectA

Ctrl+Bがデフォルトのコマンドプレフィックスキー

$ top
