Linux Journal Issue #188/December 2009
If last month's Infrastrucuture issue was too "big" for you then try on this month's Embedded issue. Find out how to use Player for programming mobile robots, build a humidity controller for your root cellar, find out how to reduce the boot time of your embedded system, and if you're new to embedded systems find out the basics that go into one. You can also read about the Beagle Board, the Mesh Potato and a spate of other interestingly named items. And along with our regular columns don't miss our new monthly column: Economy Size Geek.

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?

How Do I download Archives?
I am a subscriber to magazine [hard copy] and registered a user account but the archives do not seem easily accessable
Not Downloadable
The archives are not meant for download, they're meant for online viewing. If you want a local copy the best thing to do would be to get our Archive CD.

Ok, but what about for
Ok, but what about for subscribers of both the hard-copy and digital download bundle-pack? I didn't download last month's until this month's email came, so now I can't figure out how to get last month's issue.
Thanks!
See your subscription account
Goto your subscription account and login, then look for the digital downloads link.

Cool! Thanks. That worked
Cool! Thanks. That worked great!
I had previously found the URL, but didn't realize that the "Digital Downloads" was the right link. That url is a little heavily biased towards subscription renewal on first visit. Even clicking on the Digital Downloads link (hidden in that rather tiny menu at the bottom of the page) doesn't visually change the page enough. It's dominated by the LJ-number/Zip-Code explanation, so the relatively subtle mid-page sub-title change seems a lot like those "Find Six Differences in These Two Pictures" games from the Saturday funny papers :)
But, then, difficulty in finding the proper Login/Download link for the Digital Downloads is a charge that could also be fairly leveled at another Linux publication (of the "Pro" persuasian, in the USA at least), too.
Luckily, the Linux Journal magazine issues are awesome, once the heiroglyphics are decoded to get it!
Thanks much to you and the Linux Journal staff for all the hard work!
will see what can be done
I will see what I can do to make better process.
