For std::map, how will insert behave if it has to resize the container and the memory is not available?

Map (just like list) is a node based container; each insert allocates... .
STL map does not have to "resize" container.
The insert will not happen, and neither will the content of the dictionary be modified or corrupted .
Easy as that.
New will throw an exception.

Answer Snippets (Read the full thread at serverfault):
This will enable routing temporarily:
echo 1 > /proc/sys/net/ipv4/ip_forward
If your want this option to survive a reboot, add net.ipv4.ip_forward=1 to your /etc/sysctl.conf
HTH,

If it is just a simple packet forwarding, do what PEra suggested... .

However, you can make an ajax request....
Try this tutorial: http://www.webpasties.com/xmlHttpRequest/
A div can't behave exactly like an IFrame - An IFrame has it's own javascript environment, but a div shares the environment with the parent window.

You might....
Feed the click events from your tab button to the original radio button .
Use javascript to hide the radio buttons and create your tab buttons in place of the original radio buttons .
If you want the behavior of radio buttons, use radio buttons .

See MSDN
Using == for strings is bad practice....
Because == operator is redefined for strings.
The == operator is overloaded in the String class, in a way that makes the string values to be compared instead of the object references, which is the default .

Using vim via ssh on a machine with an x server running throws an X error. Specifically:
>vim BadWindow (invalid Window parameter) Vim: Got X error Vim: Finished.
This does not occur on my xorg-free server, so how can I force vim to behave as a console...

Answer Snippets (Read the full thread at superuser):
(or in this case vim --help ) Have you tried the -X switch? This will disable the X integration features of Vim such as clipboard integration, so X is not needed to run it. .
Moral of this story: RTFM RTFM RTFM.
DUH!
vim -X
will do it.

When you type :e some/path/file<Tab> if there are several matches, vim just picks the first one and you have to cycle through the rest of them with the Tab key. (pretty much like the behavior of the Windows CLI).
How do I make it behave like bash...

Answer Snippets (Read the full thread at superuser):
Add this to your .vimrc :
set wildmenu set wildmode=list:longest.
You can omit set wildmenu since set wildmode=list:longest implies it .
Pressing Tab multiple times steps through the matches.
