Emulate This! Part 1
email: mggagne@salmar.com
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.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

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?

Re: Emulate This! Part 1
Very cool! I never knew. Reminds me of PCTools in a way. Now I got a new book to buy.
- Peace -
Re: Emulate This! Part 1
Just gotta love mtools! I'm writing a novel in emacs and find backing up my day's work with meta-x shell and "mcopy * a:" is the easiest way to do it.
Re: Emulate This! Part 1
Marcel, Marcel, Marcel! Keep the articles coming. Discovering new things each day, and with such concise, clear, descriptive, and entertaining discussion. Love your work!
Tom
P.S. I buy your book as soon as I get a job. Don't hold your breath on this, as I've been looking since I was laid off in July of 2001.
Re: Emulate This! Part 1
mtools? Yeah, I used to use mtools. Great little package, makes dealing with a floppy from a Windows-using co-worker a lot easier.
I don't use it any more, though. Now, I just click on the little "Floppy" icon on my KDE desktop, and a Konqueror window appears (in file manager mode). I copy files and directories to/from the floppy with drag-and-drop, delete with a right-click menu, and display the contents of the file with a single click. Format? No, but, can you actually buy unformatted floppies these days?
mtools is a neat little CLI package, and is great when a CLI is called for. But for general use, there's an easier way.
Re: Emulate This! Part 1
The possibllity of forgetting to unmount the floppy before removing it is still there with a gui, even when umount is a right click away.
Anyway, great article, I hope it works with PCMCIA hard-disk, I use some at work to transfer files between Linux and window machines in situations where I can't use the network and I'm always afraid I'll forget to unmount the card before taking it out.
Re: Emulate This! Part 1
By general use I take it you mean the general populace.
mtools is useful for the sysadmin to know because there are situations where a GUI will not fit.
1. A customer at a remote site wanted to know what network card was on a particular series of PCs for the purpose of generating an install image (nothing to do with Linux). I put the hardware probe floppy image on the Linux machine using ssh and scp. I then asked her to put a floppy in the drive. I copied the image onto the floppy with dd (or cat if you wish). She took the floppy to the machine, booted it, the software did the audit and wrote the results on the floppy. She put the floppy in the Linux machine again. I extracted the log file with mcopy and read the configuration of the machine. All remotely.
2. I generate bootable firewall floppy images (not physical floppies) because mtools allows me to work on disk images of floppies. KDE has no such thing AFAIK.
So Joe Bloggs should stick to point and click, but power users would do to add another tool to their box.
