A script to generate random dates. It uses the year range 2006-2009, and truncates every month of the year to an ordinary February's 28 days, but otherwise it's pretty solid and safe.
Code:
spate=1
while [ $spate -le 120 ]

I need to generate random numbers using /dev/random in C. The numbers should be of type double (64-bit floating point).The functionality should be equal to linux command "od -An -N8 -t fD /dev/random", but written in C.The prototype should be "double drand(void);".

There you can see that it is the same number. It does that every time!! Grrr. The strange thing is each time I manually type [or copy & paste] it into the terminal, it gives random [not static, like I am getting from my script] results.
The reason I want this is because I am making a script where this line will randomly go up or down [depending on if the random number is 1 or 0].
I have this: Code: dd if=/dev/urandom count=128 bs=1 2>&1 | md5 | cut -b-10 But I only want it to have letters and no numbers. What can I do for this?

What I want is a command line argument I can pass that'll read each line and pick one of those 77 lines at random, except I can't figure out how to do this. Is there a program I can just pipe the output of 'cat listofmovies.txt' to?
View 13 Replies View RelatedI want to generate a temporary random list from a directory of files and then determine the size of an arbitrary block of files from this list (say 1-25 or 26-50) and add their names to a file along with some other info for each name. I can generate a random list with file sizes like this: ls -l | sort -R | cut -d " " -f 6 but i'm not sure how to add up the sizes of just a certain block of these files and at the same time save the file names.
View 2 Replies View RelatedI'm writing a loganalysis application and wanted to grab apache log records between two certain dates. Assume that a date is formated as such: 22/Dec/2009:00:19 (day/month/year:hour:minute) Currently, I'm using a regular expression to replace the month name with its numeric value, remove the separators, so the above date is converted to: 221220090019 making a date comparison trivial.. but.. Running a regex on each record for large files, say, one containing a quarter million records, is extremely costly.. is there any other method not involving regex substitution? here's the function doing the convertion/comparison

I'm trying to calculate the minutes difference between two dates using the function mktime() on c++. The dates will be passed to me as struct tm, and I will use this function many many times. The example below shows what I wanna do:

Does anybody know how to generate excel charts from C, or if it's possible at all?
For example, if I had 2 arrays that I wanted to export to excel and graph against each other. I know how to export it to a csv file, that's no problem, but I have no idea where to start with generating a graph of the data. I can't seem to find any examples anywhere.
I'd appreciate if someone could point me in the right direction.
Just a simple example to show you what I mean code...
I have a file, two columns, first column has a list of 15000 (yes 15k) unique codes, second column has the afilliate codes of 60 locations repeated to fill out the 15000 rows of unique codes. I need to produce a nice neat paper voucher which will fit onto A6 (1/4 A4) and is ready to print. Each voucher has the unique code and corresponding location. So far I am thinking PHP will do the job. This does it somewhat, but doesn't let be split the fields between the ",". I did this so far in PHP

The most problem is the $OS this string can verry long or verry short be. Fedora release 12 (Constantine) or RedHat 5.4 i can do that after the variables place the "stars" on the write position?

I.Comment out the first definition of *character-set*, by adding a semicon at the beginning of the line.

IV.Uncomment the second definition, which uses a word length of four.
i would like to generate :
10-character combinations of the following characters (lowercase) 23456789abcdef with no more then 3 same letters repeates no metter side by side or within one line (sequence) so lets say

fabcde1234 accept
ffabcd1234 accept
which is probably permutation with repetable string ( where abc is not equeal to cba etc .so ti speak position does metter)
fffabc1234 not acceptable -----(3 same characters)
ffabcf1234 not acceptable -----( 3 same characters event thought not side by side)
we dont want 3 same characters apper in same line.

What is the minimum possible MySQL query to get a random data selection that includes each Index number only once and ordered ascending. The maximum index number is known. For example running the query should get the following data: 01, 06, 07, 02. Running the query again, you may get the same data or another possible combination like: 01, 05, 07, 04. Of course you could run a loop for 1 to max_index and process a random ordered data selection until the next index number is found. But I think this will result in too many database access. Also you could run max_index queries to get all IDs that correspond to the given index and randomly select one ID for each index.
I tried googling around but i cant find anything related to this: everyone seems just interested in random numbers, so when it comes to random letters there is a lack of informations. However, i am trying to figure out a wait to get a random letters string that matches a simple rule: it must be a sequence of consonant+vowel. So for example, these are some 6 letters strings i would like to obtain: wolupa, tafoke, zewevu, cupimo.

My attempt to do that was with:
