* 基本的なユーザーモデル (任意の修正や削除が可能)。
* **Alembic** マイグレーション。
* **CORS** (Cross Origin Resource Sharing (オリジン間リソース共有))。
* **Celery** ワーカー。バックエンドの残りの部分からモデルとコードを選択的にインポートし、使用可能。
* Dockerと統合された**Pytest**ベースのRESTバックエンドテスト。データベースに依存せずに、全てのAPIをテスト可能。Docker上で動作するので、毎回ゼロから新たなデータストアを構築可能。(ElasticSearch、MongoDB、CouchDBなどを使用して、APIの動作をテスト可能)
* Atom HydrogenやVisual Studio Code Jupyterなどの拡張機能を使用した、リモートまたはDocker開発用の**Jupyterカーネル**との簡単なPython統合。

  The question remaining is: Which level of offline mode will we support? It
  seems reasonable to assume that users will be able to tell when localhost is
  not active (in most cases, localhost should be available, even if the rest of
  the network is not). Therefore, let's concentrate on the state where no
  network <beyond localhost> exists, and leave the more extreme state to users
  to diagnose and correct as necessary.

      byte[] buf = new byte[min(bufSize, MAX_ARRAY_LEN - totalLen)];
      bufs.add(buf);
      int off = 0;
      while (off < buf.length) {
        // always OK to fill buf; its size plus the rest of bufs is never more than MAX_ARRAY_LEN
        int r = in.read(buf, off, buf.length - off);
        if (r == -1) {
          return combineBuffers(bufs, totalLen);
        }
        off += r;
        totalLen += r;
