Linux can only go to 256 cores. Windows 2008 tops out at 64.

Linux supports more than 256 cores.

MAINLINE:

Maximum number of CPUs / CONFIG_NR_CPUS:

This allows you to specify the maximum number of CPUs which this kernel will support. The maximum supported value is 512 and the minimum value which makes sense is 2. This is purely to save memory - each supported CPU adds approximately eight kilobytes to the kernel image.

I know SGI has systems running 4096 CPUs with SUSE Linux.

"a new filesystem notification interface called fanotify"

This code was merged, but the interface to use it has been removed, as there were some concerns. So it cannot be used right now.

Root Privileges Through Linux Kernel Bug 131

Lars T. writes "The H has a story about a Linux kernel bug that allows root level access. 'According to a report written by Rafal Wojtczuk (PDF), a conceptual problem in the memory management area of Linux allows local attackers to execute code at root level. The Linux issue is caused by potential overlaps between the memory areas of the stack and shared memory segments.' SUSE maintainer Andrea Arcangeli provided a fix for the problem in September 2004, but for unknown reasons this fix was not included in the Linux kernel. The bug is not related to the X Server bug found by Brad Spengler." As the linked article notes: "SUSE itself has the fix and SUSE Linux Enterprise 9, 10 and 11 as well as openSUSE 11.1 through 11.3 do not exhibit this vulnerability."

That's also going too far. It's one thing what an employee does on company time and with company's resources, but they do on their own time - as long as it's legal shouldn't be a company's business.

If it is public anyone can watch you. As long as they don't interfere on your free time activities, it should be fine.

I wonder whether slashdot could sue solidat for copyright infringement ;-)

Novell Changes Enterprise Linux Kernel Mid-Stream 96

darthcamaro writes "Enterprise Linux kernels, from Red Hat or Novell, don't change version numbers inside of a release, right? While that has been the case for the last decade of Red Hat and Novell releases, Novell is breaking the mold with SUSE Linux Enterprise 11 service pack one. Instead of backporting new kernel features to the kernel they originally shipped with — which maintains software and hardware vendor certification — they've re-based their Linux kernel version altogether. '"There were some things that led us to update the kernel itself, which is something that we normally don't do: Neither SLES 9 or SLES 10 got a kernel update," Markus Rex, director of open platform solutions at Novell, told InternetNews.com. "But in this particular case, after deep discussion with our ISV and hardware vendors that gave us certifications, we felt in this case a kernel update was the appropriate step to take.'"

Submission + - systemd - a new sysvinit/upstart replacement (0pointer.de)

nikanth writes: systemd — a new-style init replacement, which Lennart Poettering(works for Redhat, known for pulse audio) and Kay Sievers (works for Novell, known for udev) have been working on the last months in secret.

It supports on-demand service activation(like inetd for all sorts of sockets including UNIX), on-demand-mounting(autofs), full parallel job execution, full and race-free service isolation and management by cgroups, full udev device integration, simple cron-like features for services, early syslog using the kernel log buffer, D-Bus management API, interactive bootup, emergency shell, ... Before any service is started, the configured unix sockets of the services will be created by pid 1 and any requester will be suspended by the kernel exactly until the actual service becomes available and handles the request. The same for mount-points which are natively handled by systmed and the kernel's autofs. That way we can ignore most of the dependencies we have today, the requesters will not fail, they will sleep in the kernel as long as the service/mount is not initialized.

Upstart maintainer Scott James Remnant has responded.

It is just that who ever has got into Linux Kernel Development never quit. I am a Linux Kernel developer since 2.6.25 or roughly for the past 2+ years. I see plenty of new young people getting involved/addicted with Linux. The point is those who are aging are not retiring which isn't a bad thing at all.
