GTD 学习


GTD还提出了关注重点的”六层次法“。 作者用高度的概念做了一个类比:


当然,5万英尺以上的高空是我们偶尔会想到,但是多数让我们感到迷失的地方。”我是谁?我的人生方向?我为什么生活?“ 我们需要这些思考。但是每天给我们更多压力的往往来自跑道和1万英尺以下的低空,我们在各种行动和项目之间忙忙碌碌。这些永远也处理不完的工作和生活任务让我们感到难以转移的焦虑。

John the Ripper 状态

A: As of version 1.8.0, the status line may include: successful guess count ("g"), session duration (in the D:HH:MM:SS format for days, hours, minutes, and seconds), progress indicator (percent done and optionally pass number out of the total number of passes), up to four speed metrics ("g/s", "p/s", "c/s", and "C/s"), and the current (range of) candidate password(s) being tested (John is often able to test multiple candidate passwords in parallel for better performance, hence a range). The four speed metrics are as follows: g/s is successful guesses per second (so it'll stay at 0 until at least one password is cracked), p/s is candidate passwords tested per second, c/s is "crypts" (password hash or cipher computations) per second, and C/s is combinations of candidate password and target hash per second. Versions of John prior to 1.8.0 displayed only the C/s rate (calling it c/s). When you restore a pre-1.8.0 session with version 1.8.0 or newer, only the g/s and C/s rates will be displayed, because the older .rec file format lacked information needed to compute p/s and c/s.

tr 'r' 'n' < macfile.txt > unixfile.txt
Here, r and n are special escape sequences that tr interprets as Ctrl-m (a carriage return) and Ctrl-j (a line feed), respectively. Thus, to convert a Unix text file to a Mac OS text file, enter:
tr 'n' 'r' < unixfile.txt > macfile.txt
