別に, 英単語でもなくてもいいけども.
テキストでの
「問題」と「解答」
のペアを覚える方法.
昔ながらの「書いて覚える」という方法とともに
「カード」を使った方法も効率的だろうと思います.
いまどきは, だれもがスマホを持ってる時代.
スマホは 世界中で喋られてる言語をある程度流暢に喋ることができますよね.
そんなスマホをつかって, 目だけでなく, 耳も使って効率的に
「音声付きカード」スタイルで単語を覚えていく方法をば.
homebrew で jad を入れようとする その前に「brew tap」?
Jarとかclassファイルをデコンパイルしてくれるやつ。
brew tap homebrew/binary
brew install jad
さらっと, 眺めて jad いれてみようと,

Android Studio [Help] メニューから [Search] で設定項目に素早くたどりつけるようになってた件
しれっと機能追加されてたのか,
いや, 気付かなかっただけのか.
上部メニュー[Help]から[Search]に設定したい単語を入力すると,
その下に関係する設定項目がプルダウンなかんじでサジェストされるのですが,
そのサジェスト項目を選択すると,
上部のメニューそれぞれが自動でビロ～ンとプルダウンされて,
どこからその設定画面に行けるのか分かりやすくなってる.
例)「import」関連の設定項目を探したい場合
設定項目が多くて行ったり来たりして, めんどくさかった設定変更が
素早く移動できて設定の試行錯誤したいとき便利になってます.という話.
以下, 「Find Action」と併用すればさらに便利になるでしょう.
フローティング できる Android アプリ フレームライブラリ「Tooleap SDK」
こんな風にアプリをシステム系レイヤにのせて
他のアプリ上に常駐表示させることができる
Android 向け SDK が無料で公開されている.
[APP][2.2+] Tooleap - The Multitasking SDK - xda-developers
Androidアプリでフローティング型のUIを実現できるソフトウェア開発キット「Tooleap SDK」がリリース | juggly.cn
開発者向けページもしっかりある.
フローティングできるフレームなライブラリを構成するクラス群は,
公式の Android SDK に近いレベルで構成している模様.
com.tooleap.sdk Class Hierarchy (Tooleap SDK)
だが, しかし, 無料とはいえ,
adb コマンドで 補完 させる
adb コマンドがめんどくさい場合は
コマンドを補完(completion)してもらいましょう.
何が補完できるか.
・オプション
・サブコマンド
・デバイスにインストールしているパッケージ名
・ローカル/リモートファイル名
・パソコンに接続しているデバイスシリアル名
