(Untitled)
The original plan was to have some program sI wrote to be added to the procps or util-linux package but the maintainers haven't been responsive. Therefore here they are in a package on their own.
I call the package putils (available from my private server) and the following programs are available so far:
plimitShow or set the limits of a ( Read more... ) -
pagein
I've updated the pagein tool to compile with a recent valgrind version. The tarball also contains a .spec file. I had to work around a bug in valgrind in Fedora 16 and 17.
The tarball -
Cancellation and C++ Exceptions
Cancellation and C++ Exceptions
In NPTL thread cancellation is implemented using exceptions. This does not in general conflict with the mixed use of cancellation and exceptions in C++ programs. This works just fine. Some people, though, write code which doesn't behave as they expect. This is a short example:
#include #include #include

IDN Support
glibc has IDN support for getaddrinfo and getnameinfo for quite some time. It has to be explicitly enabled in the calls, though. Now that I can actually test this I’ve enabled IDN support in the getent program which comes with glibc. This screenshot shows getent in action. Apparently the site doesn’t use an IDN CNAME yet.

Fedora and USB Mobile Broadband
Outside the US I use a USB stick for Internet access. It is a Huawei E161, similar enough to other sticks like E160 etc.
Inserting it into a standard Fedora 12 system causes only the simulated CDROM to be mounted. This dual-mode is the root of the problem.
Looking for a solution one comes across many different solutions. The provider I use, ( Read more... ) -
glibc 2.10 news
I might need a bit more space to explain the new features in glibc 2.10 than can reasonably be written down in the release notes. Therefore I’ll take some time to describe them here.
POSIX 2008
We (= Austin Group) have finished work on the 2008 revision of POSIX some time ago. In glibc 2.10 I’ve added the necessary feature select macros and ( Read more... ) -
Fedora 10 a little bit more secure
Fedora 10 comes with filesystem capability support. Unfortunately it is not used by default in the packages which can take advantage of it. I think the excuse is that there people who build their own kernels and disable it. That's nonsense since there are many other options we rely on and which can be compiled out ( Read more... ) -
Secure File Descriptor Handling
During the 2.6.27 merge window a number of my patches were merge and now we are at the point where we can securely create file descriptors without the danger of possibly leaking information. Before I go into the details let's get some background information.
A file descriptor in the Unix/POSIX world has lots of state associated with it. One bit ( Read more... ) -
dual head xrandr configuration
ajax told me that extra wide screens now work with the latest Fedora 9 binaries for X11. So I had to try it out and after some experimenting I got it to work. To save others the work here is what I did.
Hardware:
- ATI FireGL V3600
- 2x Dell 3007FPW
I use the free driver, of course. No need for 3D here.
The old way to get a spanning desktop was to ( Read more... )
