This article is a follow-up to Red Hat Enterprise Linux 5.1 utilizes nested paging on AMD Barcelona Processor to improve performance of virtualized guests.
With new hardware releases, customers are faced with situations in which they want to take advantage of increased speeds but are forced to stay on older hardware because their operating environments are not supported on the newer hardware. Virtualizing their operating environment helps them get past this issue. Virtualization also helps them:
RHEL 5 virtualization lets customers virtualize their existing systems and take advantage of the benefits mentioned above. » Read more
Last month, I wrote about confining the user with SELinux. I explained that–as of Fedora 9–SELinux supports the concept of the confined user and comes with 5 confined user types defined.
These confined users are a great starting point, but what if you want to create a confined user with different privileges? » Read more
By default, gnome-terminal does not spawn a login shell. To use a login shell for all gnome-terminal windows for a particular user in gnome-terminal, you can use gnome-terminal preferences dialog:
"Edit" -> "Current Profile" -> "Title and Command" and select "Run command as a login shell"
Alternatively, using the command line tool "gconftool-2" will achieve the same result:
# gconftool-2 --type boolean --set /apps/gnome-terminal/profiles/Default/login_shell true
To set this as a default option for all users, use gconftool-2 to set the default value of the key "login_shell" to "true" in the GConf database. As root, run the following command:
# gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults --type boolean --set /apps/gnome-terminal/profiles/Default/login_shell true
Users will still be able to change that default value on a per user basis using the preference dialog in gnome-terminal. » Read more

As promised, we have the first of the slide decks from the Summit sessions:

[ODP] slides by Michael DeHaan from his talk given Thursday June 19, 10:15 a.m.
And we still have a few more news items and blog entries about the Summit:
Today Creative Commons launched the Case Studies Project, a large community effort to explore and document the use of Creative Commons around the world. At the same time, Creative Commons Australia is holding a conference on “Building an Australasian Commons.” There the project is being announced with the publication of a publicly available booklet featuring some of the best global case studies.
Despite having just launched, the site is already full of studies. A few you’ve heard of. Most you probably haven’t. Here are a few I thought were interesting:
- Architecture for Humanity. “Design like you give a damn.” Co-founder Cameron Sinclair won a 2006 TED prize for the project. How do they use CC? “We use the Developing Nations licence for the designs of our buildings. Once the first prototype building is completed, we can essentially give away the designs to other communities in other developing nations.”
- Blender. If you’ve done any 3D animation, you know about this successful open source project. The entire production files of two movies–Elephants Dream and Big Buck Bunny–are released under the Creative Commons Attribution License.
- The University of Southern Queensland OpenCourseWare. This project applies the Creative Commons Attribution-Noncommercial-Share Alike 2.5 Australia license to ten courses. From October 2007 to March 2008, there were over 26,000 visitors to the site. The most popular class? C++.
The Case Studies Project is set up wiki-style, so it’s just waiting for your contributions.
We’re still collecting all the news, updates, and postings from the Red Hat Summit. Now that our teams are back in the office, the real work of compiling all the video, audio, and materials we gathered has begun.
We know you’re all clamoring for more than links–the most popular question has been about the session and keynote videos and slide decks. The first few keynote videos are up at the Summit web site. We’ll be adding more as soon as some legal and liscensing issues are dealt with.
The slide decks are also on their way. The first few should be available this week, with more to follow.
And it won’t all be recap–also coming up are several articles that follow up on Summit and FUDCon topics, from the same folks that presented them in Boston. » Read more
FUDCon comes on the heels of the Red Hat Summit, with many of the speakers and developers doing double-duty. Even Red Hat’s CEO showed up for both events. Did you miss out? Never fear, there’s always another FUDCon coming up, and the Fedora Project Leader is happy to give you the report from this one.
The Fedora Users and Developers Conference (FUDCon) is in full swing on its second day. We have another full day of exceptional hacking taking place on the third floor of the Hynes Convention Center in Boston. Just as the Red Hat Summit is drawing to a close downstairs–winding up with a half-day of sessions and panels–we’re just now kicking into high gear. This has been an exceptional way to introduce open source customers to the larger ecosystem behind the products they love, and the community that powers Fedora, the upstream for Red Hat Enterprise Linux. » Read more
