Kibana cannot perform aggregations across fields that contain nested objects. It also cannot search on nested objects when Lucene Query Syntax is used in the query bar.
Kibanaは入れ子になったオブジェクトを含むフィールドをまたがって集約を実行することはできません。 クエリバーでLucene Query Syntaxが使用されている場合も、入れ子になったオブジェクトを検索できません。
Using include_in_parent or copy_to as a workaround is not supported and may stop functioning in future releases.
回避策としてinclude_in_parentまたはcopy_toを使用することはサポートされておらず、将来のリリースで機能を停止する可能性があります。

Readerクラスのインスタンスを作って city()で IP アドレスを渡せばよい。Readerクラスは __init__(self, fileish, locales=None, mode=0)となっているので modeに以下のいずれかを渡すことでモードの指定が可能。
MODE_MMAP_EXT - use the C extension with memory map.
MODE_MMAP - read from memory map. Pure Python.
MODE_FILE - read database as standard file. Pure Python.
MODE_MEMORY - load database into memory. Pure Python.
MODE_FD - the param passed via fileish is a file descriptor, not a path. This mode implies MODE_MEMORY. Pure Python.
MODE_AUTO - try MODE_MMAP_EXT, MODE_MMAP, MODE_FILE in that order. Default.

alias コマンドを引き数を付けずに (あるいは -p オプションを付けて) 実行すると、エイリアスのリストが 「alias name=value」の形で標準出力に出力されます。引き数を与えた場合には、valueを与えられた name それぞれに対するエイリアスが定義されます。valueの末尾に空白があると、エイリアスが展開されたときに、空白の次の単語についてエイリアス置換があるかどうか調べられます。引き数リスト中に valueが与えられていない name があった場合は、それぞれに対して名前とエイリアスの値が出力されます。エイリアスが定義されていない name が指定された場合以外は、alias は真を返します。

新入社員入社シーズン。企業によっては技術研修等を行っている時期でしょうか。私はつい先日まで出張講師で LPIC/LinuC を教えていたのですが、Linuxはやはり実機で覚えるのが一番だと思います。しかし、会社の資産である Windows PC で Windowsを削除して Linuxをインストールするというのはなかなか受け入れてもらえません。
そのため、USB メモリから Linuxを起動する方法を用いるのですが、実機を使って USB メモリひとつひとつに Linuxをインストールするのはとても大変です。そこで、パワーのあるマシンで仮想マシンを作成してマスターイメージを作成し、Linuxがインストールされた USB メモリを量産する方法を使います。
ddコマンドやディスクイメージライターで USB メモリにイメージを書き込みます。ここでは USB メモリが /dev/sdbに接続されているものとします。ブロックサイズ等はご自由に指定してください。macOSの場合は diskutils listコマンドで USB メモリのデバイスパスを確認してください。

以前、「EasyWine はバンドル化に対応していない」という書き込みを目にしたことがありますが、バンドル化の機能を実装しないのには理由があります。Wine は Windows OS を無限に複製出来ると言っても過言ではありません。安易にバンドル化の機能を実装するとバンドル化したそれを安易に配布してしまう人が必ず出ててくると思っているので実装していません。それを言ったら仮想化ソフトウェアは皆同じですし、既に Wine に関してはネット上にたくさんの情報があるので今更そんなこと考えても…と思ったりもするのですが。
