# zsh: corrupt history file /home/marc/.zsh_history | |

cd ~ | |
mv .zsh_history .zsh_history_bad | |
strings .zsh_history_bad > .zsh_history | |

var cv = document.getElementById('cv'); | |
var c = cv.getContext('2d'); | |
var txtDiv = document.getElementById('txt'); | |
var fileBtn = document.getElementById("up-button"); | |
var img = new Image(); | |
img.src = 'a.jpg'; | |
img.onload = init; // 图片加载完开始转换 | |
fileBtn.onchange = getImg; | |
// 根据灰度生成相应字符 |
## Problem | |
When login in, the shell prints: | |
``` | |
manpath: can't set the locale; make sure $LC_* and $LANG are correct | |
``` | |
## Solution | |
``` | |
sudo locale-gen "en_US.UTF-8" | |
sudo dpkg-reconfigure locales |
A little while ago I started using Typescript with the Angular 1.5 app I'm working on, to help ease the migration path to Angular 2. Here's how I did it. We'll go example by example through migrating real world code living in a large, mostly non-Typescript codebase.
Let's start with a few of the basic angular building blocks, then we'll go through some of the higher level patterns we derived.
// Declare the color as RGB; SASS will treat this as hex | |
$green: rgb(27,224,63); | |
// Declare an alpha | |
$alpha: .5; | |
// Declare another color variable as a color with an alpha | |
$greenAlpha: rgba($green, $alpha); | |
body { | |
/* As RGB (which SASS actually ouputs as HEX) */ | |
background: $green; |
