Linux Counter
The experiment has been running since October 1993 and has so far registered more than 4,500 Linux users. Data from other sources indicate that this may be somewhere between 0.5% and 5% of all Linux users.
All the reports are available for anonymous FTP from aun.uninett.no, directory pub/misc/Linux-counter, and are updated every hour.
How to register
Send E-mail to Linux-counter@uninett.no with the SUBJECT line
“I use Linux at place” where place is one or more of school, work, or home. You will get back a letter with 3 things:
An acknowledgement
A form that you can fill out and send in with more information about yourself, your machine, and your 386Linux-using friends
A report giving the current status of the counter
You can update your “vote” at any time, by sending an E-mail message from the same account. Duplicates will be weeded out.
Privacy issues
The counter will NOT give out any information about individual persons. The only exception is this:
If the person writes the following:
//PERSON Name: (my name is.....) may-publish: yes
this is taken to mean that his name, E-mail address and country can be published in the report called “persons”, which might be useful for people
wanting to meet other Linux users.
You can remove permission at any time, by sending in another registration with this field set to “no”.

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?
