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?

ALSA write up
Hi Dave,
Great write up on ALSA. When is your next one coming out?
Thanks,
Travis
Overall, good info
I found the article to be quite helpful overall. I was initially confused about setting up my system to play MIDI files. It would have been more clear if the author would have emphasized that not all sound cards have a wavetable they can use for playing MIDI. I spent several hours chasing my tail and on Google trying to play a MIDI file on my T23 laptop and an Intel 800 series chipset with AC97 sound. I slowly came to the slow realization that Timidity++ is the only hope on it.
Meanwhile, I found the brief note of his SB Live! card helpful by at least giving me a lead. I have an SB PCI-512 card that also uses the emu10k1 driver and digging out the original CD revealed a file named 8MBGMSFX.SF2 on it. A bit of Googling revealed that this was the needed file and indeed, playing MIDI files now works.
I realize some of these low-level details aren't necessarily a function of ALSA, but since much of the article was devoted to MIDI and sequencing, I think they should have been developed a bit more. For all of their popularity, modern soundboards are largely a mystery for most of us.
Once we can listen to streaming audio or a CD, most of us consider the audio to be installed. My thanks to Mr. Phillips for an interesting article with many new ideas to explore.
