Roll a die twice for each digit and then use the following table: First Roll 1 2 3 4 5 6 S 1 1 2 3 4 5 * e 2 6 7 8 9 0 * c 3 1 2 3 4 5 * o 4 6 7 8 9 0 * n 5 1 2 3 4 5 * d 6 6 7 8 9 0 * Roll the first die again when ever you get a *. Each random digit adds 3.3 bits of entropy. Note: You really don't need the table to use this method: Just roll a die until you get a number that isn't 6. Then roll the die again. If the second result is even, add 5 to the first number you got. Treat a ten as a zero.

Roll dice twice for each hex digit and then use the following table: First Roll 1 2 3 4 5 6 S 1 0 1 2 3 4 5 e 2 6 7 8 9 A B c 3 C D E F 0 1 o 4 2 3 4 5 6 7 n 5 8 9 A B C D d 6 E F * * * * There are also d16 dice marked 1 to 16, but you have to remember that 10 is A, 11 is B, 12 is C, 13 is D, 14 is E, 15 is F and 16 is 0. One source is:

Just roll dice twice for each character and then use this table: First Roll 1 2 3 4 5 6 S 1 A B C D E F e 2 G H I J K L c 3 M N O P Q R o 4 S T U V W X n 5 Y Z 0 1 2 3 d 6 4 5 6 7 8 9 If you only want letters, roll the dice again when ever you get a digit. Each random letter adds 4.7 bits of entropy.

To create passwords of maximum strength for a given number of characters, you must use all available symbols. This is especially important for most Unix systems where passwords are limited to eight characters from the 7-bit ASCII printable character set. The following set of three tables allows you to create such a password.

Some computer systems insist that a special character be included in your password. Here is how to make them happy. Roll the dice twice and then use the following table: First Roll 1 2 3 4 5 6 S 1 ! @ # $ % ^ e 2 & * ( ) - = c 3 + [ ] { } \ o 4 | ' ; : ' " n 5 < > / ? . , d 6 ~ _ 3 5 7 9

You need to do this if you want to insert one random character in your passphrase for added security, as mentioned in the main Diceware page. Here is how this is done. Pick the column in the table below that corresponds to the number of characters in the chosen word. Then roll one die and look up the number you get on the left hand side of the table. Insert the random character after the selected letter. Zero means put the random character at the beginning of the word.

QBasic can be found on the Win95 CD-ROM in the 'OTHER\OLDMSDOS' directory. All you have to do is copy QBASIC.EXE and QBASIC.HLP to your hard drive from the directory.

The dice has the face value of 3 , 4, 6, 8 and blanks. When the dice is tossed by the Challenger and it shows a 3 , 4, 6, or 8, the Defender picks one of his or her cards and forms a word of length no more than the dice number within the timeframe. If the Defender fails to form the word within the timeframe, he has to surrender one of his cards to the bottom of the draw deck.

Dewey numbers are not shown in the Brief Record display which is the first screen to appear for a single catalog record. However, they are available in the Online Catalog. The Dewey number is displayed in either the Full Record or MARC Tags displays, accessed by clicking on the tabs at the top of the Brief Record display. You can search the new catalog by Dewey number using Keyword, Guided Keyword with Keyword Anywhere selected, or the Command Keyword search using the index code K082.

You can read a brief explanation of how the dice work on our Lucky 6 page. The exact mathematical details are not available to players or members.

The notation "[0,1)" is common math notation for "zero to .9999999 etc" The Sun documents say this returns 0.0 to 1.0, but inspection of the source shows they are wrong. However, due to the inherent inaccuracies of floating point arithmetic, multiplying N by 0.999999 etc can result in an answer of N, not N * .999999 . So watch out when N is big.

All the basic level worksheets here begin with positive integer values, that is, positive whole numbers, and zero. Decimal values in the advanced addition, subtraction, and multiplication worksheets include 2 digits to the right of the decimal place. In the division worksheets, decimal is used to indicate problems that do not have whole number answers -- they can be used to practice calculations where "remainders" occur, or for the calculation of decimal answers.

First, be sure you understand exactly what numbers mean in the old familiar decimal system. If I write 3409, what it really means is 3*1000 + 4*100 + 0*10 + 9*1... I can also write it as: 3*103 + 4*102 + 0101 + 9*100 (remember that 100 = 1). Now there's nothing magic about 10 - it was chosen because we happen to have 10 fingers. If humans had 7 fingers, you can bet that we'd be writing numbers like this: 3204 = 3*73 + 2*72 + 071 + 4*70.

The standard module random implements a random number generator. Usage is simple: import random random.random()

rand() is used to generate a random number between its first value and its second value. Eg. var/num = rand(1,10) will set num to a random number between one and ten. prob() is used to check a probability out of 100; it will return 1 if the check is true, or 0 if the check is false. For example, prob(50) will have a 50% chance of returning 1 and a 50% chance of returning 0. prob(25) will have but a 25% chance of returning 1 and a 75% chance of returning 0.

Two good places to learn this are the TimeZone Classics created by the co-author of this FAQ entitled ??? 1027: The Definative Answer to 'How Do I Use The Tachymeter' ??? and ??? 1178 How to use 4 different types of Bezels... ???.

All stands in a group fire shoot, but they don't shoot all together. For example, when three rifle stands group fire, you don't throw the 9d6 all together (6d6 into cover); instead each stand makes it own attack with 3d6 (2d6 into cover). The advantage of group fire is not that you throw more dice, but that if any shooting stands suppress or kill, then initiative is retained, and all stands have the option to fire again.

I've never done it, but I know it must be possible because the tgdb package in the Tcl archive uses all of those extensions with Expect. I've done this kind of thing by hand. It's pretty simple. But people tell me the make-a-wish package in the Tcl archive automates the creation of multi-extension Tcl applications.

We go to great lengths to make sure that the numbers are picked as randomly as possible. Why is that important? It assures that we get old and young people, rich and poor people, conservative and liberal people ? and everybody in between. Let's say the computer is about to pick a telephone number from your area code and telephone exchange. There are 10,000 possible telephone numbers.

Yes, this is normal and expected. The current system stores some information in a hidden field which is serialized and zipped. The field appears as a very long stream of random characters. Do not delete or modify this field or the form will become unusable.
