Hi,
I believe the next code is wrong:
class Egg {
Egg e;
int i;
Egg(int ii=0) : i(ii) {}
};
because you would end up with an endless definition (memory allocation) of Egg objects, thus int i.
Ok, so God Eckel proposes for a singleton:
class Egg {
static Egg e;

We have got a USB HDD with important data in it. The data has been copied to the disk(formatted ext3) via a LINUX system.
The data was supposed to be copied to a second LINUX machine. Surprisingly, it doesn't show up any valid partitions in the new box.

snd_uaudio
SND_UAUDIO(4) BSD Kernel Interfaces Manual SND_UAUDIO(4)
NAME
snd_uaudio -- USB audio device driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device sound
device usb
device snd_uaudio
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
snd_uaudio_load="YES"
DESCRIPTION
The snd_uaudio driver provides support for USB audio class devices.
A USB audio device consists of a number of components: input terminals (e.g. USB digital input), output terminals (e.g. speakers), and a num-
ber of units in between (e.g. volume control).
Refer to the 'USB Audio Class Specification' for more information.
SEE ALSO
sound(4), usb(4)
USB Audio Class Specifications, http://www.usb.org/developers/devclass_docs/.
HISTORY
The snd_uaudio driver first appeared in FreeBSD 4.7.
AUTHORS
This manual page was adopted from NetBSD 1.6 and modified for FreeBSD by Hiten Pandya <hmp@FreeBSD.org>.
BUGS
The PCM framework in FreeBSD, as of this writing, does not handle device un-registrations in a properly abstracted manner, i.e., a detach
request is refused by the PCM framework if the device is in use. For USB and supposedly other detach-able busses, it is necessary to allow
the device un-registration to complete successfully, otherwise the driver leaves wild pointers to invalid data structures and thus leading to
a panic.
