I have read a document which tells me the following 4 things are done by the RAM embedded on disk driver controller. But I don't know what's difference between buffer and cache. Thanks!

1 firmware
2 speed matching buffer
3 prefetching buffer

Happy New Year!
There are currently four UNIX.COM achievement awards up for grabs, as the say. Here they are, in no particular order:
The Order of the Raven
The Order of the Hippo
The Order of the Spider
The Order of the Dragon
Don't ask me what they mean, or who who will get those... (0 Replies)
Dear All,
Here is the current status of the badging system:
The Beta 1 phase of the new badging system is close to completion.
42 prototype badges have been "allocated"
6 prototype badge slots are held in reserve
The "alert you have new badges" prototype is running and is currently... (4 Replies)

Another major upgrade on the new UserCP today. I have created the "My Badges" page in the new control panel, and it's looking very cool :)
If you have visited the new UserCP recently, you will more-than-likely need to close your browser (completely) and then restart it to clear out the old... (2 Replies)

io::async::protocol::linestream
IO::Async::Protocol::LineStream(3pm) User Contributed Perl Documentation IO::Async::Protocol::LineStream(3pm)NAME
"IO::Async::Protocol::LineStream" - stream-based protocols using lines of text
SYNOPSIS
Most likely this class will be subclassed to implement a particular network protocol.
package Net::Async::HelloWorld;
use strict;
use warnings;
use base qw( IO::Async::Protocol::LineStream );
sub on_read_line
{
my $self = shift;
my ( $line ) = @_;
if( $line =~ m/^HELLO (.*)/ ) {
my $name = $1;
$self->invoke_event( on_hello => $name );
}
}
sub send_hello
{
my $self = shift;
my ( $name ) = @_;
$self->write_line( "HELLO $name" );
}
This small example elides such details as error handling, which a real protocol implementation would be likely to contain.
DESCRIPTION EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_read_line $line
Invoked when a new complete line of input is received.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
on_read_line => CODE
CODE reference for the "on_read_line" event.
METHODS
$lineprotocol->write_line( $text )
Writes a line of text to the transport stream. The text will have the end-of-line marker appended to it; $text should not end with it.
