I have Red Hat 7.1 running IMAP, POP3 and POP2 from the University of Washington. The services do not accept client access with the login root and password, but other users are okay.
—Pedro Guedes, pmg01@netc.pt
The easiest thing to do is set up an alias for root in /etc/aliases to a non-root user. Don't forget to run newaliases after updating /etc/aliases.
—Christopher Wingert, cwingert@cwingert.qualcomm.com
You definitely should not try to login to an IMAP or POP server as root, especially if you aren't using SSL. You would be sending your root password in clear text for anyone to steal.

I have a ThinkPad 600 with an external floppy. How do I mount the floppy drive? (I was able to mount the CD-ROM no problem.) I've tried mount /dev/floppy, mount /dev/fd0 and mount /dev/fb0, but none of those work.
—Zachary Grant Michael, zachary.michael@earthlink.net
See if your floppy drive is detected at boot time with:
dmesg | grep -i floppy
If you see a line
Floppy drive(s): fd0 is 1.44Mthen your floppy is device /dev/fd0. To mount it, type
mount /dev/fd0 /mnt/floppy—Usman S. Ansari, uansari@yahoo.com
I have a ThinkPad 570 with an external floppy, and it is detected as /dev/fd0. After you mount with the above command, you might want to customize /etc/fstab with the name of your floppy device and your chosen mount point in order to simply type mount /mnt/floppy. See man 5 fstab for how to do this.

I am an Australian schoolteacher, and I am looking for a database to use with our Linux network. I want a database that is similar to Microsoft Access, because it is easy to use and teach to students.
—Ken Jordan, kwjordan@cedars.nsw.edu.au
There is a tool called pgaccess (<@url>pgaccess.org) that works with PostgreSQL and very closely resembles the functionality of Microsoft Access. Another alternative is to use the OpenOffice.org database connection facilities through ODBC.

Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.
Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?
