Quote: Make bootable usb from bootable cd on Windows

quote from:
http://www.ehow.com/how_5942169_convert-bootable-iso-bootable-usb.html

1

Insert your USB drive into the USB slot in your computer. Open a command prompt window by going through the “Start” menu and searching for “command prompt.” Type “diskpart” into command prompt and press “Enter.” Enter in “list disk” and see what disk number your USB flash drive is. Enter in “select disk #” with # being the disk number of your USB drive. If your USB is disk 3, you would enter in “select disk 3.” Type in “clean” and your USB drive will be erased.

2

Type in “create partition primary” followed by “select partition 1.” Type in “active” and then “format fs=fat32.\" Finally enter in “assign” and type in “exit.” Your USB is now ready to have the ISO put onto it. Copy and paste your bootable ISO file into your USB flash drive. Alternatively, you can mount the ISO file as a virtual drive with Daemon Tools, which is available in the resource section of this guide. Once mounted, open a new command prompt window and enter in “xcopy d:\\*.* /s/e/f e:\\.” The drive letter “d” is the mounted ISO drive and the drive letter “e” is the USB drive. If your ISO is drive X and USB is Y, the command will be “xcopy x:\\*.* /s/e/f y:\\.”

3

Reboot your computer and enter into the BIOS settings by pressing the “F2” button when you see your computer manufacturer’s name. Go to “Boot Options,” and set your USB drive as 1st priority. Press the “F10” button to save your settings, and your computer will reboot from the USB drive.

金句-Fight Club

我找到了自由，拋開所有希望就是自由

I found freedom. Losing all hope was freedom.　

我要到洞裡找我的精神動物

不要用快死的人的方式躲避疼痛

我在這裡看到了最強最聰明的人

你們都很有潛力

但都被浪費了

你們只是做一些替人加油

或是上菜

或是打領帶上班的工作

廣告誘惑我們買車子、衣服

於是拚命工作買不需要的東西

我們是被歷史遺忘的一代

沒有目的

沒有地位

沒有世界大戰

沒有經濟大恐慌

我們的大戰只是心靈之戰

我們的恐慌只是我們的生活

我們從小看電視

相信有一天

會成為富翁、明星或搖滾巨星

但是…我們不會

那是我們逐漸面對著的現實

所以我們非常憤怒

抛棄一切…才有自由

No fear. No distractions.

工作不能代表你

You are not your job

銀行存款其不能代表你

You're not know much money you have in the bank

你開的車也不能代表你

You're not the car you drive

皮夾裡的東西不能代表你

You're not the contents of your wallet

衣服也不能代表你

You're not your fucking khakis

你只是平凡眾生中的其中一個

You are the all-singing, all-dancing crap of the world

七二法則

七二法則是用於計算在某段時間之內成長到原有價值兩倍的方法。

倍數成長年限＝７２／成長率

真是這麼神奇？

Code:

import math print (('%5s %5s %5s') % ('%', '72/I', 'Actual Year')) for i in range(1, 101): actual = 0 j = 1 k = 1+i/100 while j < 2: j *=k actual += 1 print (('%5d %5d %5d') % (i, math.floor(72/i), actual))

Result:

% 72/I Actual Year 1 72 70 2 36 36 3 24 24 4 18 18 5 14 15 6 12 12 7 10 11 8 9 10 9 8 9 10 7 8 11 6 7 12 6 7 13 5 6 14 5 6 15 4 5 16 4 5 17 4 5 18 4 5 19 3 4 20 3 4 21 3 4 22 3 4 23 3 4 24 3 4 25 2 4 26 2 3 27 2 3 28 2 3 29 2 3 30 2 3 31 2 3 32 2 3 33 2 3 34 2 3 35 2 3 36 2 3 37 1 3 38 1 3 39 1 3 40 1 3 41 1 3 42 1 2 43 1 2 44 1 2 45 1 2 46 1 2 47 1 2 48 1 2 49 1 2 50 1 2 51 1 2 52 1 2 53 1 2 54 1 2 55 1 2 56 1 2 57 1 2 58 1 2 59 1 2 60 1 2 61 1 2 62 1 2 63 1 2 64 1 2 65 1 2 66 1 2 67 1 2 68 1 2 69 1 2 70 1 2 71 1 2 72 1 2 73 0 2 74 0 2 75 0 2 76 0 2 77 0 2 78 0 2 79 0 2 80 0 2 81 0 2 82 0 2 83 0 2 84 0 2 85 0 2 86 0 2 87 0 2 88 0 2 89 0 2 90 0 2 91 0 2 92 0 2 93 0 2 94 0 2 95 0 2 96 0 2 97 0 2 98 0 2 99 0 2

結論：

成長率在６或以下就準確，在７到３６需要加１

Using Unix Document Format:

Either set default using Unix Document Format when create a new document (Settings, Preferences, New Document/Default Directory)

or set the current document to Unix format (Edit, EOL Conversion, Convert to Unix format)

When edit the python script file. Using UTF-8 without BOM. Rather than UTF8 and ANSI.
