Got ink?

Shadowman on your shoulder?
Fedora on your forearm?
Tux on your tush?

We’re looking for people with Red Hat, Fedora, Creative Commons, and other awesome open source and related tattoos to feature in the magazine.

Even better, have you been thinking about getting some new geek ink but haven’t yet? Have a friend videotape it and send us the footage.

If you’re interested in showing off your ink, drop us a line.

Thanks!


Tips and tricks: How do I capture the output of “top” to a file?

The command top is a very useful tool to capture information about process running on Linux. Many times this information may need to be captured to a file. This can be done with the following command:

top -b -n1 > /tmp/top.txt

This will run top once write the output to a file and exit.

The command top can also be run so that it will give multiple reports. To run top 5 times and wait 5 seconds between each output the command would be:

top -b -n5 -d5 > /tmp/top.txt

Video: Bela Ban

Meet Bela Ban, a developer who began the JGroups and JBoss Cache projects. He’s now the technical lead of the JBoss clustering team, continuing the work he began as an college instructor.

Ban talks about the background of both projects, as well as upcoming developments, including increased throughput, persistence, security, remote accessibility, and other features. He also discusses the business needs that can be solved with these tools–just a small sample from his talk at JBoss World.

Tips and tricks: How do I configure a Linux guest to shutdown from z/VM?

This is accomplished through the combination of the SIGNAL SHUTDOWN command from z/VM and /etc/inittab file in Linux. First, logon to z/VM as MAINT, then run the following command:

==> CP SET SIGNAL SHUTDOWN 180

This instructs z/VM to wait 3 minutes (180 seconds) for each guest to complete shutdown. Increase this value if there are services running that require longer to stop.

Friday round-up

  • An interesting development in intellectual property law, the Superman comics copyright case, is in the news again. The heirs of the original creators of Superman were given rights to Action Comics #1, a decision that splits ownership of the Superman universe. Who owns large-scale works created over time? How are they divided? In this case, some characters are owned by one entity and others by another. What are the implications for “written works” like software and applications? Interesting questions to ponder…
  • Is there such a thing as technological terrorism? You might scoff, since it’s true that most dire warnings about the dangers of the internet seem silly. But the recent Wired piece about an epilepsy discussion board hit with griefers posting flashing graphics is a bit alarming.
  • Of interest: a piece from Linux Journal on the popularity of blogs as promotional media. With a catchy title: Blogging vs flogging.
  • The PaperWorld 3D source is now open. PaperWorld lets you create 3D massively multiplayer online gaming (MMOG) environments that run in Flash.

How do you use Fedora?

Paul Frields, Fedora Project Leader, asks:

Fedora is being used in a hundred thousand interesting places out in the real world.

* At NASA to do analysis that makes future space exploration safer.
* In studies to improve development for children with Down’s Syndrome (trisomy 21).
* At Creative Commons, to promote open content discovery, creation, and remixing.
* Powering distribution of food to the needy in Mexico.

We want to hear a story about how YOU use Fedora to do something interesting. Enriching. Educational. Enhancing. At work or in your community. How did Fedora help you achieve something special? Just reply in a comment to [his] blog.

Tips and tricks: How can I increase the security of my workstations?

1. First delete the password lists for all profiles on the machine.

del c:windows*.pwl

2. From the command line:

REGEDIT /s \MY_PDCnetlogonnocache.reg

This will run regedit with no program output and a registry input file named nocache.reg, which looks like this:

REGEDIT4
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesNetwork]
"DisablePwdCaching"=dword:00000001

3. Save that as plain text and name it nocache.reg.

Following these steps will greatly increase the security of your Windows 9x machines.
