-You'll sometimes be asked to do 'back-of-the-envelope' estimates.  For example, you might need to determine how long it will take to generate 100 image thumbnails from disk or how much memory a data structure will take.  The **Powers of two table** and **Latency numbers every programmer should know** are handy references.
+暗算で、推計値を求める必要があることも時にはあります。例えば、ディスクから100枚イメージ分のサムネイルを作る時間を求めたり、その時にどれだけディスクメモリーが消費されるかなどの値です。**2の乗数表** と **全てのプログラマーが知るべきレイテンシー値** は良い参考になるでしょう。
