This week, the [Global Language Monitor] announced that "Web 2.0" became the One Millionth word of the English language. The average American only uses about 10,000 word vocabulary.
One way to improve your vocabulary is to read my blook (blog-based book), Inside System Storage: Volume I, which includes a 900-word glossary of storage-related terms. My blook is now available in hardcover or paperback at [Amazon] as well as direct from my publisher[Lulu]:
I have started working on a new book which I hope to have available for purchase later this year.Read More]
Over at Freakonomics blog,Stephen Dubner has a guest post from Captain Steve titled[What Captain Sullenberger Meant to Say (But Was Too Polite to Do So)] on the sad situation the airline industry is in.
Ideally, every airline would use the most experienced seasoned professional airline pilots money could buy, but some airlines, in an effort to compete on ticket price, may elect instead to have less experienced pilots.Here's a great excerpt:
Airline history lesson 101: It used to be, up until the mid 1980’s, that a young pilot would be hired on at a major carrier, become a flight engineer (FE), and then spend a few years managing the systems of the older-generation airplanes. But he or she was learning all the while. These new “pilots” sat in the FE seat and did their job, all the while observing the “pilots” doing the flying, day in and day out.
To become the public speaker I am today, IBM put me through a variety of speaking classes. I taught high school and college classes to practice in front of groups. But most importantly, I traveled with seasoned colleagues and watched them in action from the front row.I learned how to handle tough questions, how to react to hecklers causing trouble, and how to deal with the unexpected before, during and after each presentation. In addition to speaking skills, I ended up having to learn travel skills, foreign language skills, and a variety of cultural social skills. All part of the job in my line of work.
Likewise, being a storage administrator is an important job, and for some data centers, not something to give lightly to a fresh college graduate. Unless they have had format IT Infrastructure Library [ITIL] certification coursework, I doubt they would understand the processes and disciplines demanded by the typical data center. I have been to accounts where new hires are not allowed to touch production systems for the first two years. Instead they watch the seasoned professionals do their jobs, and are given only access to "sand box" systems that are used for application testing or Quality Assurance (QA). Sadly, I have also been to other accounts where people with no storage experience whatsoever were tossed into the admin pool and let loose with superuser passwords, all in an effort to save money during times of exponential data growth rates, only to pay the price later with outages or lost data.
The parallels between the airline industry and the IT industry are eerie.Read More]
Continuing this week's theme of doing important things without leaving town, there is a four-hour [worldwide virtual forum covering Dynamic Infrastructure] that you can attend next week without travel.
In addition to these presentations, you will be able to "walk" around to different booths and have on-line chats with subject matter experts and download resources. Don't worry, this is not based on [Second Life], but rather using "On24" much simpler visual interface.Of course, you can follow on [Twitter] or join the fan club at[Facebook].
This is a worldwide event, with translated resource materials and on-line subject matter experts in six different languages (English, French, Italian, German, Mandarin and Japanese). Those in North, Central and South Americas can participate June 23, and those in Europe, Asia and the rest of the world on June 24. [Register Today] and mark your calendars!

This week's theme: you don't have to "go somewhere" to do "something important."
Seth Godin has a great list of suggestions for do-it-yourself [graduate school for unemployed college students]. Here's an excerpt:
In 2007, 51 percent of graduating college students could find jobs in their field, and this year it has dropped to only 20 percent. If you find yourself with some time on your hands, either recently graduated or recently unemployed, consider volunteerism.Last year, I chose to donate my time and money to an innovative project called "One Laptop per Child" [OLPC]. It was one of my [New Years Resolutions] for 2008. I was actually "recruited" by folks from the OLPC after they read my [series of blog posts] on things that can be done with their now famous green-and-white XO laptop.
In recognition of these efforts, I was awarded last week the bronze[U.S. President's Volunteer Service Award] through the USA Freedom Corps and the President's Council on Service and Civic Participation.To learn more about these projects, see my [OLPC wiki page].

Continuing this week's theme of doing important things without leaving town, I present our results foran exciting project I started earlier this year.
For seven weeks, my coworker Mark Haye and I voluntarily led a class of students here in Tucson, Arizona in an after-school pilot project to teach the ["C" programming language] using [LEGO® Mindstorms® NXT robots]. The ten students, boys and girls ages 9 to 14 years old, were already part of the FIRST [For Inspiration and Recognition of Science and Technology] program, and participated in FIRST Lego League[FLL] robot competitions.Since the students were already familiar building robots, and programming them with a simple graphical system of connecting blocks that perform actions. However, to compete in the next level of robot competitions, FIRST Tech Challenge [FTC],we need to leave this simple graphical programming behind, and upgrade to more precise "C" programming.
Mark is a software engineer for IBM Tivoli Storage Manager and has participated in FLL competitions over the past nine years. This week, he celebrates his 25th anniversary at IBM, and I celebrate my 23rd. The teacher, Ms. Ackerman, and the students referred to us as "Coach Mark" and "Coach Tony".
This was the first time I had worked with LEGO NXT robots. For those not familiar with these robots, you can purchase a kit at your localtoy store. In addition to regular LEGO bricks, beams, and plates, there are motors, wheels, and sensors. A programmable NXT brick has three outputs (marked A,B, and C) to control three motors, and four inputs (marked 1,2,3,4) to receive values from sensors. Programs are written and compiled on laptops and then downloaded to the NXT programmable brick through an USB cable, or wirelessly via Bluetooth.
We used the [RobotC programming firmware] and integrated development environment (IDE) from [Carnegie Mellon University].The idea of this pilot was to see how well the students could learn "C". With only a few hours after class on each Wednesday, could we teach young students "C" programming in just seven weeks?
My contribution? I have taught both high school and college classes, and spent over 15 years programming for IBM, so Mark asked me to help.We started with a basic lesson plan:
At the completion of these seven weeks, I sat down to interview "Coach Mark"on his thoughts on this pilot project.
This is a practical programming skill. The "C" language is used throughout the world to program everything from embedded systems to operating systems, and even storage software. This would allow the robots to handle more precise movements, more accurate turns, and more complicated missions.
Can kids learn "C" in only seven weeks?
Part of the pilot project was to see how well the students could understand the material. They were already familiar with building the robots, and understood the basics of programming sensors and motors, so we were hoping this was a good foundation to work from. Some kids managed very well, others struggled.
Did everything go according to plan?
The first two weeks went well, turning on motors and having robots move forward and backward were easy enough. We seemed to lose a few students on week 3, and things got worse from there. However, several of the students truly surprised us and managed to implement very complicated missions. We were quite pleased with the results.
What kind of problems did the kids encounter?
Touch sensor required loops waiting for pressing. Motors did not necessarily turn as expected until more advanced methods were used. Making 90 degree left and right turns accurately was more difficult than expected.
Any funny surprises?
Yes, we had a Challenge Map representing the Mars planetary surface from a previous FLL competition that was dark red and divided into squares with thick black lines. An active light sensor returns a value of "0" (complete darkness) to "100" (bright white).However, the Mars surface had craters that were dark enough to be misinterpreted as a black line causing some unusual results. This required some enhanced programming techniques to resolve.
Did robots help or hurt the teaching process?
I think they helped. Rather than writing programs that just display "Hello World!" on a computer screen, the students can actually see robots move, and either do what they expect, or not!
And when the robots didn't do what they were expected to?
The students got into "debug" mode. They were already used to doing this from previous FLL competitions, but with RobotC, you can leave the USB cable connected (or use wireless Bluetooth) and actually gather debugging information while the robot is running, to see the value of sensors and other variables and help determine why things are not working properly.
Any applicability to the real world of storage?
We have robots in the IBM System Storage TS3500 tape library. These robots scan bar code labels, pull tapes out of shelves and mount them into drives.The programming skills are the same needed for storage software, suchas IBM Tivoli Storage Manager or IBM Tivoli Storage Productivity Center.
The world is becoming smarter, instrumented with sensors, interconnected over a common network, and intelligent enough to react and respond correctly. The lessons of reading sensor values and moving motors can be considered the first step in solutions that help to make a smarter planet.Read More]
