If you'd like to be able to easily see which one of your kvm guests is the cpu hog, make links from to qemu-kvm
cd /usr/local/bin
ln -s /usr/bin/qemu-kvm vm_magneto
virsh edit magneto
# change emulator to
<emulator>/usr/local/bin/vm_magneto</emulator>
virsh reload
virsh shutdown magneto
virsh start magneto
A static variable in a class method are shared between all instances of that class and not per class instance.
#include <stdio.h>
class Foo {
public:
int foo() {
static int i = 0;
i++;
return i;
}
};
int main() {
Foo a, b;
printf( "a: %d\n", a.foo() );
printf( "b: %d\n", b.foo() );
}
a: 1
b: 2

rm -r "~/Library/Application Support/SyncServices/Local/clientdata/com.llsoftware.fbevents"
I still don't know what eigenvalues are, what they're for, or how to use them, but I needed to calculate them for work and make sure they were positive.
Despite my previous [/tech/time-machine-on-a-network-drive post] on how to get Time Machine backing up to a network drive, this turned out to be flaky. So far using iSCSI has been bomb proof and without having to do anything arcane, it is likely a lot more reliable.
Since it's been two years since my last raid cost analysis, I figured it was about time to do another one.
Goals:
I saw a recent post of the most incredible maze I've ever seen. Well I just had to solve it.
I thought I had posted this ages ago, but in case anybody needs to know how, here's how you setup a virtual kvm firewall. I'm using Smoothwall but any distro would work.
Open files with jEdit from the terminal is a pain. Here's a script to help.
