test: /\.css$/,
loader: "style-loader!css-loader?modules&importLoaders=1&camelCase!postcss-loader",

Android アプリ開発勉強会のために書いた Java の入門文書

Android アプリ開発のための Java 入門

MEMO

  • declaration は 「宣言」 と訳しているが、「定義」 の方が適しているような気がしなくもない。
  • 「インスタンス」 と 「オブジェクト」 という言葉を使うことがあるが、本文書中ではどちらも同じ意味で使用している。
  • 「String オブジェクト」 という表現は、「String クラスのインスタンス」 を意味している。 (Java に限らず一般的な表現だと思う。)

How to copy production database on AWS RDS(postgresql) to local development database.
  1. Change your database RDS instance security group to allow your machine to access it.
    • Add your ip to the security group to acces the instance via Postgres.
  2. Make a copy of the database using pg_dump
    • $ pg_dump -h <public dns> -U <my username> -f <name of dump file .sql> <name of my database>
    • you will be asked for postgressql password.
    • a dump file(.sql) will be created
  3. Restore that dump file to your local database.
    • but you might need to drop the database and create it first
    • $ psql -U <postgresql username> -d <database name> -f <dump file that you want to restore>
  • the database is restored
