World Datacenter Storage at 1 ZB

Heard on the BBC World Service:

"The world is drowning in a sea of data. Facebook users alone are uploading more than a thousand photos a second. We're now seeing an exponential explosion of information. So how much information are we really storing?"

Go Guerrill-R on Your Data in August

Only one month to go! Register now for the Guerrilla Data Analysis Techniques (GDAT) class to be held during the week of August 9-13, 2010. The focus will be on using R and the PDQ-R for computer performance analysis and capacity planning.

For those of you coming from international locations, here is a table of currency EXCHANGE rates. We look forward to seeing all of you in August!

Prime Parallels for Load Balancing

Having finally popped the stack on computing prime numbers with R in Part II and Part III, we are now in a position to discuss their relevance for computational scalability.

Velocity 2010 The Aftermathglow

I was so impressed with Velocity 2009, I really wanted to present something at Velocity 2010.


Thread-limited scalability of memcached
Working with Shanti and Stefan of Oracle (née Sun Microsystems), I was able to accomplish that goal. Our session was rated 92.4%, which is an A+ in anyone's books. Congrats to us and the Velocity organizers and thank you, crowd.

Linear Modeling in R and the Hubble Bubble

Here is a scatter plot with the coordinate labels deliberately omitted.

Do you see any trends? How would you model these data?

Shanti and I will be presenting at 1300 on Thursday. The Velocity conference is being held at the Hyatt Regency Santa Clara, near Great America.

Playing with Primes in R (Part II)

Popping Part III off the stack—where I ended up unexpectedly discovering that the primes and primlist functions are broken in the schoolmath package on CRAN—let's see what prime numbers look like when computed correctly in R. To do this, I've had to roll my own prime number generating function.
