I have a page I would like to print out having <textarea> printed as well.
I would like to have this <textarea> having maximum width, and minimum height, so where there is no data it is only one line, but in case the data spans to, let's say, 10 rows, it expands <textarea> to 10 rows, and no scrollbar appears.
This is what I have found that works for me:
$(".tarows").each(function(){
$(this).height(0) ;
$(this).height($(this).prop("scrollHeight") + "px") ;
}) ;
- or similar using pure javascript:
element.style.height=0;
element.style.height=element.scrollHeight+'px';
This way, I can define my textarea (using class tarows) without cols or rows, and say in css to make it 100% width:
.tarows {
width: 100%;
}
<textarea class="tarows">multiline text which will be shown on the whole width of the page, and as many rows as needed.</textarea>

If you see:

Then the problem is with your file system.
Check the status of the file system that holds your /tmp directory.
I bet it is full.
Clean the /tmp directory or delete unneeded files/directories in the file system and you will be good to go.

Life is Worth Living, CD 11 order of mp3
Something out of the ordinary of this blog...
The "Life is Worth Living, CD 11" has incorrect mp3 order (sequence.)
Just in case someone decided to look for proper here is the correct one:

GDB - Accessing deque and queue
In O1 mode some of the functions are optimized out and it is impossible to call them.
In case of deque and queue (which is build over deque) it is a bummer for the size() method is calculated.
After finding some examples on the Internet we found nothing usable (I guess because our gcc was using different deque memory structure.)
So we created a new version.
pdequeue_info variable
- Shows size, first, and last element
pdequeue variable [firstidx [lastidx]]
- Shows contents or a range.
define pdequeue_info
set $var=($arg0)
set $sizeof=sizeof( **$var._M_impl._M_start._M_node )
set $size=$sizeof < 512 ? ( 512 / $sizeof ) : 1
set $i=0
while $i < $var._M_impl._M_map_size && $var._M_impl._M_map[ $i ] == 0
set $i++
end
set $rv = 0
while $i < $var._M_impl._M_map_size && $var._M_impl._M_map[ $i ] != $var._M_impl._M_finish._M_first
set $rv += $size
set $i++
end
if $var._M_impl._M_map[ $i ] != 0
set $rv += $var._M_impl._M_finish._M_cur - $var._M_impl._M_finish._M_first
end
printf "size : "
p $rv
if $rv > 0
printf "first : "
p *$var._M_impl._M_start._M_cur
if $rv > 1
printf "last : "
p *( $var._M_impl._M_finish._M_cur - 1 )
end
end
end
define __pdeque_show_group
set $cur=($arg0)
set $size=($arg1)
set $f=($arg2)
set $l=($arg3)
set $j=0
while $j < $size && $n <= $l
if $n >= $f
printf "[%i] : ", $n
p *$cur
end
set $cur++
set $j++
set $n++
end
end
define pdequeue
set $var=($arg0)
set $f=-1
set $l=9999999999
if $argc == 2
set $f=($arg1)
set $l=$f
end
if $argc == 3
set $f=($arg1)
set $l=($arg2)
end
set $sizeof=sizeof( **$var._M_impl._M_start._M_node )
set $size=$sizeof < 512 ? ( 512 / $sizeof ) : 1
set $i=0
while $i < $var._M_impl._M_map_size && $var._M_impl._M_map[ $i ] == 0
set $i++
end
set $n=0
while $i < $var._M_impl._M_map_size && $var._M_impl._M_map[ $i ] != $var._M_impl._M_finish._M_first && $n <= $l
__pdeque_show_group $var._M_impl._M_map[$i] $size $f $l
set $i++
end
if $var._M_impl._M_map[ $i ] != 0 && $n <= $l
__pdeque_show_group $var._M_impl._M_map[$i] $var._M_impl._M_finish._M_cur-$var._M_impl._M_finish._M_first $f $l
end

valgrind - dowloading, building and installing
First, I need to post all the links that will allow you to get to the creators information:
* WWW: http://valgrind.org
* Manual: http://valgrind.org/docs/manual/valgrind_manual.pdf
* Source: http://valgrind.org/downloads
* Building Instruction: http://valgrind.org/docs/manual/dist.readme.html
Building
* Download the source and put into your home account. Let's assume it is the valgrind-3.6.1 version.
Run these commands:
Now, what you have is a $HOME/valgrind directory. If this is place where you want to use it then you are ready. The only one thing you need to do is set your path: export PATH=$HOME/valgrind/bin:$PATH
Ok... and what about if you need this valgrind now on a machine that does not have gcc?
The only thing you need to do is to pack the whole $HOME/valgrind directory, and copy it over to the destination machine.
The only caveat is that it has to be put into exactly the same directory as it was built in or else you will see this nice message:
valgrind: failed to start tool 'memcheck' for platform 'amd64-linux': No such file or directory
Solution - ln -s $HOME/valgrind path-to-valgrind-on-the-build-machine
Example: ln -s $HOME/valgrind /home/myhome/valgrind

tar xf $vver.tar.bz2
cd $vver
ulimit -u 100 # ./configure has a bug ...
./configure --prefix=$HOME/valgrind # You need that in order to run make install without root privileges
make
make install
cd $HOME/valgrind/bin
./valgrind ls -l # see if it bombs out. If it does not you are good to go

Internal Server Error when password protecting directory
Do you see something like that:???
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster@blahblah and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
There is a very simple explanation but it took me lots of time to discover the reason. Well, I'm not as good as I would like to be ;)
The reason -> FILE PERMISSION!!!
All directories have to have +xr access for the web server. You may have to make o+xr them.
Also the .htpasswd and .htaccess have to be accessible for the web browser.
Here is my .htaccess in the directory I want to have password protected:
Since the web server is 'hosted', so the best thing to do is to run the phpinfo() on the web browser (create p.php file and put <?php phpinfo(); ?> in it) and look for DOCUMENT_ROOT to see where really are your web files located.
Make sure that all the directories leading to .htpasswd and .htaccess are having proper 'read/execute' attributes (644)
