OpenSUSE :: Warning: Cannot Convert String To Type FontStruct

Jun 9, 2010

I used xbindkeys and xvkbd to map my extra mouse buttons to page up and page down. With kde 4.4 it worked, but since I upgraded to kde 4.5 beta, I get the following error when xbindkeys starts:


*** Warning ***verify that there is not another program running which captures one of the keys captured by xbindkeys. It seems that there is a conflict, and xbindkeys can't grab all the keys defined in its configuration file. And for button press I get

General :: Data Type In Programming?

Jun 14, 2010

I declared a variable as int data type which was a placeholder for a resulttatus (meaning, based on the result status that variable varies from 0/1/2/3. It can contain only these four values).data type is 4 byte integer in C#. But I can declare this variable as which represents a 1 byte integer. Since that variable contains only 1 or 2 or 3 or 4, declaring the variable asis wastage of memory space.Before declaring any variable we need to just think of the memory space needed for that variable, our requirement,

Programming :: Double Data Type Mantissa?

Nov 23, 2010

in c/c++, double is usually 8 bytes. It has a 52-bit mantissa (or significand, or base), an 11-bit exponent, and a 1-bit sign. My question is: is the mantissa a 52-bit integer? Or is the decimal point just after the first bit. Meaning: if the mantissa was 1000110011100011 (in binary) would that make the value of the mantissa (assuming the exponent was 0) 1000110011100011, or 1.000110011100011? (in binary)

Programming :: Get And Process Stuff From JSON Encoded Serialized Data String?

Apr 2, 2010

I have this JSON encoded data, which I want to efficiently parse (i.e. fast, with minimal system resources). I don't want to use a/the shell any more than necessary.

Here's a snippet of what the raw serial data looks like:

[{"num":1,"name":"1","visible":false,"focused":false,"rect":{"x":0,"y":0,"width":1680,"height":1050},...blah blah..
So that's fine. I currently have at least two ways of parsing it:

This Perl method (which I don't much care for because I'm not much into Perl, and because the output is not much more useful than the raw form, and imho even more cryptic):

sasha@reactor: <produce data> | perl -MData::Dumper -MJSON::XS -E 'say Dumper(decode_json <>)'
$VAR1 = [

# Which means: at x=1680, draw a 20x20px grey block, then back up -10px and draw a "1" on the block.I figure that the two awk's I've used can be combined into one -- but I began having problems with removing the single quotes if I did it within the awk, which is why I stuck a `tr` in the middle.

I know this sucks. So, if someone has some ideas or thoughts on something else to do with this JSON data, that's less convoluted that where I'm currently going, I'll be happy to hear about it.

PS - I know this whole post is possibly hard to understand -- if you need more info (you mean you're interested in this mess?? )

Ubuntu :: Changing File System Type To Another Filesystem Type - Does It Effect On Data?

Feb 4, 2011

In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5

previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal

After doing(changing the file system)this one ,i couldnt see the d:drive data

By doing that

1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.

2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.

Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)

I had very imp data in d:drive

Programming :: Pthread - Take String From The Command Line And Creates A Thread To Print The String

May 3, 2011

I've been trying to understand pthread in C a little better. So I made a simple program that takes in a string from the command line and creates a thread to print the string. I've looked online and copied the basic concepts but there are something things I'm confused about. The programs works just fine, but I have questions. Here's what I have so far.


One thing I'd like to know is why the 3rd argument in the pthread_create function which is my SendMessage function needs to be typecasted to a void pointer and then send the address of the function. Also as for the 4th argument, I would see typecasting to void pointer in some of the pthread examples I saw online, but in my case I'm passing a char pointer, would this be correct? In which case would I ever want to pass a void pointer?

Do I need a pthread_exit(NULL) in my main and in the SendMessage function? If so, why? I added the sleep() function so that I could let the pthread_exit function in my SendMessage function execute first. I simply saw that the online examples on pthread had pthread_exit() in both locations.
