View 5 RepliesI have a 1TB hard drive which is formatted with FAT32. Attempting to make a new partition I clicked the format drive button in Disc Utility. I chose Master Boot Record and something was written to the drive. So now I can't mount the drive and Disc Utility says that there aren't any partitions. I don't think this can be true because I had 200 GB of data on the drive and it would have taken longer to delete all that. At least I think...

View 1 Replies View RelatedI tried to find out how awk works with multiline strings. I found this. I hope it will be useful for somebody. 1. I know that awk can searches simple patterns like '/^one/'
Code:
s="one
two
three"
echo $s | awk '/^one/'
2. I know that "Awk can handle multiline records by specifying the field separator to be a newline and set the record separator to an empty string." I've found it here

The declaration for directory record length in ext2 filesystem is as follows:
Code:
#define EXT2_NAME_LEN 255
struct ext2_dir_entry_2 {
__u32 inode; /* Inode number */
__u16 rec_len; /* Directory entry length */
__u8 name_len; /* Name length */
__u8 file_type;
char name[EXT2_NAME_LEN]; /* File name */
};
Some say because the record is not in a fixed length so rec_len is the real record length. Why is the length of the array `name' not fixed? I thought C arrays like this should be fixed length. C99 has variable-length arrays, does this structure count on C99?
My friend has a website whereby once you have logged in on one page, you are redirected to another page, with a url similar to:
[URL]
the random string changes each time you log in, however the login page has a static url What i was attempting to do is run a script to get some data from the members page (after uve logged in) - however ive been having some trouble in how to do this, as the variable url with the random string will become invalid after a certain time, and i did not want to consantly change it.
While reading through some documentation i read that wget should be able to login to a form login website however ive had no luck, the command i was attempting to use was:
wget --user USERNAME -password PASSWORD [URL]
similarly i also tried
wget --post-data "username=USERNAME&password=PASSWORD" [URL]
and even both combined. However neither has worked as the html dl'd is simply the login page website. I cannot post a direct link to the website as it is private, however ive looked at the source coding and ive extracted (what i think) is the relevant bit, which is:
Code:
<form action="/cgi-bin/sblogin/login.cgi" method="post" name="login" id="login"><br /><br />
<div class="user_text"><span class="text3">USERNAME:</span></div><div class="user_box"><input type="text" class="text" name="uname"></div>

I'm looking for some expert opinion on sed/script to work out the best way to transform one xml format into another however there are a few complexities around translation.
The extra complexities are to:
1) Take the start and stop time (YYYYMMDDHHMMSS) and convert to start time to unix time plus output the difference in seconds between both times.
2) Oid, tsid and sid are found by looking up an external file and finding the value against the channel. For example one of the lines in the file will be 2:806:27e2=channel1
Is there any way to write piped sed commands that can do this? If not, any ideas how the script should look like?
Input File
Code:
<programme start="20100910060000 +0100" stop="20100910061000 +0100" channel="channel1">
<title lang="en">This is the title</title>
<desc>This is the description</desc>
</programme>
Output File
Code:
<service oid="0002" tsid="0806" sid="27e2">
<event id="0">
<name lang="OFF" string="This is the title"/>
<text lang="OFF" string="This is the description"/>
<time start_time="1284098400" duration="600"/>
</event>
</service>
Look up file for oid, tsid and sid
Code:
2:806:27e2=channel1
2:756:37a3=channel2
5:4a06:42e5=channel3
In C++ as subjected, can anyone throw me some light on how I can generic-ly format an integer value of 1 to a string value of 0001? 11 to 0011? and 111 to 0111? simply by just appending 0 in front and limiting the length of the string to 4?

I have a series of files in the format:
Which I'm trying to split using sed to have each field/value pair on on line:
So far so simple, but some of the values might have commas in them, which means they'll be split up. Is there a way to change this so that only commas not within quotes will be replaced with ? (e.g. make sed count number of " and if it finds a , after counting an odd number of " then ignore it?)

View 10 Replies View RelatedI'm reading a book on assembly, and it talks a bit about the IEEE floating point format.
Quote:
To summarize, the following steps are used to convert a decimal number to IEEE single format: 1. The leading bit of the floating point format is 0 for a positive number and 1 for a negative number. 2. Write the unsigned number in binary. 3. Write the binary number in binary scientific notation f23.f22 ... f0 2^e, where f23 = 1. There are 24 fraction bits, but it is not necessary to write trailing 0's. 4. Add a bias of 127 to the exponent e. This sum, in binary form, is the next 8 bits of the answer, following the sign bit. (Adding a bias is an alternative to storing the exponent as a signed number.) 5. The fraction bits f22f21 ... f0 form the last 23 bits of the floating point number. The leading bit f23 (which is always 1) is dropped.

View 5 Replies View RelatedI was wondering, what would be a good, open-source file format for a beginner in the field, like me, to start editing sound files? This file format would have to be well documented, preferibly open-source, lossless and, most of all, convertible to more popular file formats, such as mp3 or wav maybe. I would like to design my own sound effects through directly editing the binary sequence of a sound file. I imagine this editing would have the purpose of adjusting the voltage variations of the sound device's output in time. It would be perhaps something like a PC-controlled signal generator. I'm thinking I might be able to do this in linux with something like
Code:
$ dd if=mysound.raw of=/dev/audio
But then, which book or resource woule be a good and through explenation of the relationship between the bit sequence in mysound.raw and the signal function generated in the output of, say, my computer's sound card.
