Fedora 16

Once again after the installation of a new version of Fedora things have changed.

Grub has become grub2 and the administration of it is different. The first change I had to deal with is the setting of the default boot partition.



Fedora 15

I have installed Fedora on my guinea pig machine. Things went pretty smoothly apart from two problems.

1. selinux was stopping openvpn from working. The simple solution is to disable selinux like I usually do.
2. Bluetooth is not enabled and started by default on F15. This seems to be a bug. The steps to enable it require interacting with the new systemctl utility.

systemctl status bluetooth.service
sudo systemctl enable bluetooth.service
sudo systemctl start bluetooth.service


C++0x feature support in GCC 4.5

Here is a description of some nice new features available in C++0x supported by GCC 4.5.


Here are some highlights.

Static assertions:

static_assert(sizeof(int) == 4, "Integer sizes expected to be 4");

New character types

char16_t guaranteed to be able to hold a UTF-16 character
char32_t guaranteed to be able to hold a UTF-32 character

Auto syntax type

auto *num1 = new int(7); // type for num1 it int*
const auto num2 = 3.1415; // type for num2 is double

Initializer lists

// in a variable definition
std::vector doubles = {2.3, 4.511, 1.23, 0.99};

// Initializer list used with new
std::list *d2 = new std::list {1.2, 1.3};

// Initialize a map
std::map = { {“key1”, 1}, {“key2”, 2} };

Thanks to the Fedora forums:

If tail -f file gives "too many open files"

If tail -f file gives "too many open files" then add this to your /etc/sysctl.conf

Or interactively:
