I've taken a course in the past that covered unix/linux and I have one coming up my final semester. The course I took covered the command line using mainly the bash shell and a few programs like vim and emacs. Anyways I wanted to practice a little at home since alot of programming jobs want unix or linux experience.
I was wondering what is the unix/linux defacto programming environment or do people actually use vim and emacs for that? Also do people still use the command line alot and if so why? I really don't see the advantage of using the command line as compared to using a GUI. Also what distro would you recommend I try?
thanks for you help.

Mike command line and GUI are two different worlds. Most jobs that require UNIX / LINUX experience involve you writing shell scripts, scripts that automate processes etc. They don't really require you to develop a GUI.
The defacto programming enviornment for GUI based apps differ because of variety of choices Linux offers  . KDevelop, Eclipse, Glade Designer, MonoDevelop are some of the great GUI development tools available. Some distributions have this in-built into them.

Each distro has its own plus and minus. However OpenSUSE 11 was my fav because i came inbuilt with so many dev tools that i rarely needed to connect to internet to download them.
I found the articles written by pseudonym67 at codeproject are a great place to start if you are looking for learning gui development in Linux, though i never spent time in reading them  . Hope I do that this diwali.

I have written a simple article on MonoDevelop to consume web services.
http://lamp.codeproject.com/KB/webservices/MonoStockInformation.aspx[^]
As you can see, development in Linux seriously lacked proper articles and was the birth-right of a few people. I personally remember during my college days browsing through page 10 of google search results to learn APIs in Linux. But I feel with the LAMP section of CodeProject this would change and there would be wonderful articles that can teach development in Linux

you will need to compile each file separately. each file creates a different exe, one will create a client exe and the other a server exe.
each file has a main method, when you compile files together it to create a single exe, so what you are doing is incorrect. in short you can't have multiple definitions of a function, in your case that would be 'main'
try:
gcc -o server server.c
gcc -o client client.c
hope this helps

Dear friends,
I'll appreciate if anyone could help me this problem.
I'm now trying to program with multi-core. For instant, with C/C++, how can I assign a task for the first core and another task for the second core? Is there any instructions support this? Or could you show me where can I find any documents relate to this field.
Thank you very much.

I think pthreads handle this automatically, but I don't know how much manual control you can get. Maybe this Linux magazine article (google cache) helps.

You can use the sched_setaffinity() system call to lock a thread to a specific set of CPUs/cores. In most cases doing that is a bad idea and it will only slow down your system.

Thank you very much. This instruction was created so it must have some useful functions beside causing system slow down. But first of all, I need to try it. Once again, thanks.

hi i would like to know how to sort my dynamic generated table in php when i click on any header row on first click sort acending and on another click sort on decending order.
|
|
|
|
|
If you wanna sort Mysql Data, you should use two difference Mysql Query.
For example :
SELECT * FROM table1 ORDER BY filed ASC
SELECT * FROM table1 ORDER BY filed DESC
Else if you wanna sort a table in client you should use JavaScript.
|
|
|
|
|
ya i know these are two commands to show asc and desc but i would like to know that i have a grid table in php and on every field i want to do this and show a image full process to do this this grid is filled by while loop as used in php all dataare there but i want to show sorting on header of the fields click.
thanks for reply

I think you want to load a table and then be able to sort the data by a column after the data is loaded by clicking on the col header, correct? Uh oh, i think i may like jQuery too much as i just posted a different response pointing the user to the jQuery library.
Take a look at ajaxrain.com for table plugins to jQuery. I know there's a couple of them out there, if this is what you're looking for

There would be 3 components to this process-
1. User-facing page with <div id=data></div>
2. AJAX Javascript
3. Dynamic PHP page
The user-facing page will contain an empty div marked by an ID. The AJAX script will be something like-
http://whatsaranjit.com/includes/grabData.js[^]
Lastly, the PHP page will contain a script like-
$sql = "SELECT * FROM table";
if (isset($_GET['q'])) {
$q = $_GET['q'];
$sql .= " ORDER BY $q ASC";
}
On your user-facing page, you can make your table header a hyperlink-
<a href='javascript: grabData('headerName', 'data', page.php)'>Sort</a>
When you click the link, it will refresh the SQL query data into the div named 'data' appending the SQL query to order by whatever variable you pass to the AJAX script. You can expand on this to to get it to ascend/descend. Good luck!

If any one knows about this, please help me.
Thanks in Advance

Have you tried following function?
unsigned long XGetPixel(XImage *ximage, int x, int y);
For more information you can see man XGetPixel.

You could always make this field a VARCHAR (10) instead, which means that the field can take a null value; then, just insert any actual dates in the format YYYY-MM-DD, leaving fields blank where you want to, and then when you read the data from the database again, check if it's not null and if so parse it using a function like date_parse().
