How to configure Single-Server Private Network in Xenserver without using VLAN?

How to configure Single-Server Private Network in Xenserver without using
VLAN?

I would like to create a Single Server private Network on a Xenserver
which will be used for communication between the host and the VMs. I am
able to achive this by creating a vlan and configuring the pif.
But when looking at the XenCenter, there is an explicit option to create
such a network without the VLAN stuff. Where would I configure it using xe
or Xencenter commands? I can see it in network-list, ifconfig and brctl,
but where would I set the local IPs?

Continue slideshow with Unslider

Continue slideshow with Unslider

I'm using Unslider at the moment and I'm wondering if there is any way to
make the slideshow continue to the right when switching from the last
slide to the first one. At the moment it goes through all the slides from
right to left when jumping to the first one from the last.
If that isn't possible, is it possible to make it go backwards from the
last one instead? Like this:
1 - 2 - 3 - 4 // 4 - 3 - 2 - 1 // 1 - 2 - 3...
Really appreciate answers! Thanks!

Onchange 1st date picker, 2nd datepicker will change

Onchange 1st date picker, 2nd datepicker will change

in my form, i have 2 datepicker (eg : date1, date2). Date1 is approval
deadline and date2 is confirmation daedline. Approval deadline should be
equal or more than confirmation deadline.
So. I want if user change date2, date1 will automatically change
accordingly (same as input for date2). But whenever date1 is change, it
will effect itself only (only date1 change). Hopefully you can understand
this situation.
I think that this can be done using jquery, but i'am new in jquery, i hope
that you guys can help me. Thanks.

Global variable not staying set, maybe caused by fork()

Global variable not staying set, maybe caused by fork()

I'm trying to write a very very simple unix shell in C, and I have the
basics of what I need working, except support for a history command. I
have a global 2D char array that holds the history of all entered
commands. Commands are added before the fork() system call, and I was
originally printing out the value of the history global array after
strings were added, and they were printing out correctly, so I'm not sure
why it doesn't print out when the command "history" is used at the shell.
Thank to anyone who takes a look.

Call to constant pointer-to-member function not being inlined

Call to constant pointer-to-member function not being inlined

Now, I know there are no guarantees for inlining, but...
Given the following:
struct Base {
virtual int f() = 0;
};
struct Derived : public Base {
virtual int f() final override {
return 42;
}
};
extern Base* b;
We have that:
int main() {
return static_cast<Derived*>(b)->f();
}
Compiles down to:
main:
movl $42, %eax
ret
Yet...
int main() {
return (static_cast<Derived*>(b)->*(&Derived::f))();
}
Compiles down to:
main:
pushl %ebp
movl %esp, %ebp
andl $-16, %esp
subl $16, %esp
movl b, %eax
movl (%eax), %edx
movl %eax, (%esp)
call *(%edx)
leave
ret
Which is really saddening.
Why is that call to PMF not being inlined? The PMF is a constant expression!
