Microsoft SQL Server sa account password setup

首先要先安裝 Microsoft SQL Server Management Studio Express (以英文版為例) (可在 Microsoft 的網站下載)

1. 首先，點選 Object Explorer -> (Your Database) -> Security -> Logins -> sa，就會出現如下圖的視窗，將 Password 、 Confirm password 鍵入你想要的密碼。

2. 接著，點選小視窗左方的 Status，將 Login 的 Disabled 改成 Enabled (預設可能是 Disabled，因為 sa 是 SystemAdministrator 的帳號，權限很大)。

3. 重新開機(非必要，但是如果無法登入可以重開再試試看)

4. 重新開啟 Microsoft SQL Server Management Studio Express 後，在登入畫面將 Authentication 改為 SQL Server Authentication，接著在Login 、 Password 分別鍵入 sa、你所設定的帳號，就可以用 sa 帳號登入，也表示你可以寫程式透過這組帳號密碼來連接資料庫。

I wanted to setup MySQL to use utf-8 on the MAMP installation on my Mac.

Use NVM to handle Angular-Node.js incompatibility (e.g., Uncaught SyntaxError: Unexpected token 'export')

Overview If you are a fullstack developer, the chances are that you will be creating multiple frontend or Node.js projects along the way. When you are creating new projects using the newest version of the cli (command-line interface) of a particular framework, you might be asked to install the most updated version of Node.js in order to utilize the newest feature. This might involve upgrading your Node.js version, which might not be compatible with other existing projects (e.g., using Angular) you have created before. A potential solution is to use nvm (Node Version Manager) to install multiple versions of Node.js and use a particular version of the Node.js to install the proper version of the cli (e.g., Angular-CLI) that can be used to manage a particular project. Here I will use a problem I run into to explain how to solve it. Problem There is a compatibility issue between Node.js and angular.js. For instance, I run into an error when I was using an incompatible version of Node.js
