MOTD::Last Fall 2008 Posting
The 34th edition of the MOTD ends today (Saturday, 27 December 2008) and the 35th edition will start on Thursday, 1 January 02009. The 35th edition of the MOTD will switch to using 5-digit years, but other than that no other MOTD changes are currently planned.

The MOTD (Message Of The Day) was started during the fall of 1997 and I have updated it on a weekly basis for almost eleven years.

The MOTD is a blog (web log); however, when I created it, blog was not the popular term that it is today. I used MOTD because of my Unix experience. When you log onto a Unix system, you are greeted with the message-of-the-day which is stored in the file /etc/motd. Typically, only a super-user can edit the /etc/motd file.

Computing::An Interview With Bjarne Stroustrup
Thank You to KevinM for passing along a hyperlink to a recent interview with Bjarne Stroustrup--the father of C++. Since 2002, Stroustrup has been the College of Engineering Chair in Computer Science at Texas A&M University.

   "The old Bell Labs (AT&T Bell Labs) was indeed remarkably close to 
    the ideal for practical research aimed at changing the world for 
    the better and I'm often 'homesick' for it. Unfortunately, it no 
    longer exists."

Another Stroustrup quote...

   "A friend of mine looked at the final projects of a class of 
    third-year CS students from a famous university. Essentially 
    all had their code littered with 'magic constants.'" 

And I liked Stroustrup's reply when asked "what is it that makes a great developer?"

   "Curiosity, initiative, tenacity, ability to reason logically, 
    ability to communicate and to work with others. That's not at 
    all special for programmers, I'm afraid. Also, I strongly prefer 
    to be around people with a sense of humor."

Math::Modifications to the MBNA
MathBabbler is doing more and more nBABs (number BABs) thanks to his MBNA (MathBabbler Number Analyst [software]). The PrimeFactors of the MBNA prints the prime factors of composite numbers and he modified the code to print if a number is semi-prime (also called bi-prime or 2-almost prime). Semi-prime numbers are have two (not necessarily unique) prime factors.

   $ PrimeFactors 33
   33 has the prime factors: 3*11
   33 is semiprime (biprime or 2-almost prime)

   $ PrimeFactors 88
   88 has the prime factors: 2*2*2*11

   $ PrimeFactors 1679
   1679 has the prime factors: 23*73
   1679 is semiprime (biprime or 2-almost prime)

   $ PrimeFactors 4
   4 has the prime factors: 2*2
   4 is semiprime (biprime or 2-almost prime)

GDT::Math::MBNA::PrimeNumbers C++ source code

While working on a nBAB about the number 88, MathBabbler learned that 88 was a refactorable number. A refactorable number is a number that is evenly divisable by a count of its divisors (including the divisors 1 and the number itself).
   $ DeficientPerfectAbundant 88
   88 proper divisors are: 1,2,4,8,11,22,44,
   88 is refactorable (evenly divisable by # of divisors)
   88 is abundant (sum of divisors is 92)

   $ DeficientPerfectAbundant 32
   32 proper divisors are: 1,2,4,8,16,
   32 is deficient (sum of divisors is 31)

   $ DeficientPerfectAbundant 16
   16 proper divisors are: 1,2,4,8,
   16 is deficient (sum of divisors is 15)

   $ DeficientPerfectAbundant 36
   36 proper divisors are: 1,2,3,4,6,9,12,18,
   36 is refactorable (evenly divisable by # of divisors)
   36 is abundant (sum of divisors is 55)

Computing::2020 FLOSS Roadmap
It's a 78-page dot-pdf and I haven't read it, but I probably will during the next couple of months. I'm glad to see they used FLOSS when referencing Free/Libre and Open Source Software.

I agree with ComputerWorld's reporting...

   "Reaching this computing nirvana, however, will require action 
    -- and not just by bearded geeks. Investors, legislators, 
    educators, voters and even consumers also have a role to 
    play, according to the report's authors."

Speaking of beards... I'm confident there are a lot of geeks around the world who are beardless; in fact, I suspect most female geeks don't have beards.

Computing::Internet2 Continues To Evolve
The headline "Internet2: Full Speed Ahead" caught my attention and full speed ahead is right. The following was copied from ACM.org/TechNews.

   "Internet2's high-speed network is expected to be a key 
    component in the testing of predictions of high-energy 
    physics when CERN's Large Hadron Collider becomes fully 
    operational in 2009. The collider is expected to generate 
    approximately 15 million gigabytes of data per year, and 
    more than 70 Internet2 university members and 3,000 American 
    researchers will participate in the research, with each

Internet::InterPlanetary Network is Working
Vinton Cerf has played a key role in the development of the Interplanetary Internet.

   "NASA is celebrating a successful test of a deep-space network 
    modeled after the Internet. Engineers from NASA's JPL have 
    transmitted images to and from a NASA spacecraft using 
    disruption-tolerant networking (DTN) software. NASA says 
    DTN and 'interplanetary Internet' technology will be used 
    in future space missions."

Technology::DARPA Budget Needs Increasing
PCWorld.com reported that the the U.S. Department of Defense took an "estimated 1,500 computers offline Wednesday after a security breach within the Office of the Secretary of Defense (OSD)."

"I don't do e-mail," said Secretary of Defense Robert Gates. "I'm a very low-tech person."

Our next Secretary of Defense must be a very high-tech person because cyber-warfare, bio-warfare, nano-warfare and robo-warfare could be stark reminders that the United States of America has been asleep at the wheel.

"September 11 was essentially a collision of early 20th-century technology: the airplane and the skyscraper. We don't want to see a collision of 21st-century technology," said Bill Joy in 02006.

The United States needs to say 02008 is the 01958 of the 21st century; therefore, DARPA's current annual budget of approximately $3.2 billion needs to be increased at least ten-fold.

Computing::IBM Into Cognitive Computing
Cognitive computing is using computing to simulate and emulate the human brain.

   "Computer systems that mimic the brain to process large amounts 
    of data could emerge from a $4.9 million collaboration between 
    IBM, five universities and DARPA. The SyNAPSE project could tap 
    the value of real-time information growing at 60 percent a year. 
    Being able to analyze the data could make real-time decisions 
    possible."

SyNAPSE stands for Systems of Neuromorphic Adaptive Plastic Scalable Electronics.

And the five universities are: Stanford, Wisconsin-Madison, Cornell, Columbia University Medical Center, and California-Merced.

Computing::About Sun Microsystems
On 14 November 02008, Sun Microsystems Inc. announced it plans to "cut up to 6,000 jobs, or 18 percent of its global work force."

Sun Microsystems has been a great American computer company since 01982. When I think about Sun Microsystems, I think about the Stanford University Network and how the "network is the computer." I think about the company's outstanding support for the Unix operating system. It is impossible to forget that during the mid-1990s, Sun created the Java "write once, run anywhere" platform and applets helped spawn the growth of the world wide web (interactive web pages... woohoo). Now in the early part of the 21st century, Sun Microsystems has become a key participant in the evolution of open source with computing tools such as OpenOffice, MySQL, OpenSolaris, and (most recently) Java.

So many great computer professionals have worked at Sun Microsystems over the span of the last quarter of a century. I've heard some people advocating Bill Joy for CTO (Chief Technology Officer) of the United States. It would be great if Obama picked Joy for that position, but I have no idea if Joy is interested.

It is known that there are an infinte number of worlds,
simply because there is an infinite amount of space for
them to be in. However, not every one of them is inhabited.
Any finite number divided by infinity is as near nothing as
makes no odds, so the average population of all the planets
in the Universe can be said to be zero. From this it follows
that the population of the whole Universe is also zero, and
that any people you may meet from time to time are merely
products of a deranged imagination.

Computing::Under My Cloud
ASU is really excited about getting into "cloud computing."

   "To practice cloud computing, you have to have a cloud," 
    notes Adrian Sannier, ASU's university technology officer. 
   "That's the obstacle most universities have. A cloud is 
    a big thing, and it's very expensive."

A "cloud" is basically a cluster of computers working together as a single computer accessed via a growing cyber-infrastructure.

   "We'll start with an overview of important computing models.
    Then, we'll learn programming in Google style." -- Dan
    Stanzione, director of the high-performance computing 
    center at ASU's Fulton School of Engineering and a member 
    of the faculty team that will teach the cloud-computing course. 

Stanzione is a computing guru and ASU is lucky to have him as a technical leader.

   "ASU is the largest user of Google Apps, says Kari Barlow, 
    assistant vice president of the university's technology 
    office." -- Knowledge@W.P. Carey

"Cloud computing" makes it seem as if we're entering into an era of utopian computing... but are we?

The Guardian did an interview with Richard Stallman (RMS) and they quoted RMS saying it was "worse than stupidity" when it comes to using web-based programs like Google's Gmail.

RMS is a guru programmer who created the GNU Project and he is the founder of the Free Software Foundation.

   "It's stupidity. It's worse than stupidity: it's a marketing 
    hype campaign.  Somebody is saying this is inevitable -- and 
    whenever you hear somebody saying that, it's very likely to 
    be a set of businesses campaigning to make it true." -- RMS

Stallman is one of the most trustworthy computer professionals in the world; therefore, I usually listen when he speaks.

   "One reason you should not use web applications to do your 
    computing is that you lose control. It's just as bad as 
    using a proprietary program. Do your own computing on your 
    own computer with your copy of a freedom-respecting program. 
    If you use a proprietary program or somebody else's web 
    server, you're defenceless. You're putty in the hands of 
    whoever developed that software." -- RMS

Are ASU students becoming "putty" in the hands of Google?

Google is a 21st century Informatics company and ASU (and UA and NAU) must be failing at producing talented 21st century informaticians.

I was surprised Google came to Arizona given our 20th century political leadership. Google coming to Arizona was a gift to Arizona's politicians--too bad they weren't able to use that gift to turn Arizona into a respected software state. What a wasted opportunity.

Google leaving Arizona prompted lots of postings to AzTalk. One poster wrote: "This is not surprising. Google is 10 years old and has had its good days. From now on it's all down hill." Bottom-line: Google is 10 years young and Arizona is too ancient for them.

Google is exiting Arizona and that is good news for Google shareholders.

Computing::Sarah Palin's Yahoo! Email Account Cracked
Wired is correct to state: "The simplicity of the attack, of course, makes it no less illegal."

   "As detailed in the postings, the Palin hack didn't 
    require any real skill. Instead, the hacker simply 
    reset Palin's password using her birthdate, ZIP code 
    and information about where she met her spouse -- the 
    security question on her Yahoo account, which was 
    answered (Wasilla High) by a simple Google search."

Palin is now being critized for conducting work business using her Yahoo! email account.

Blog.Wired.com::Palin E-Mail Hacker Says It Was Easy

[Extra] I posted the following to the my AzFoo@AzCentral.com blog.

Sarah Palin's Yahoo! email account was cracked (not hacked) by a cracker (not a hacker).

People who criticize Palin's computing practices should be careful because there is a good chance many of us are using our computers in non-secure ways. For example, I suspect over the span of the last decade lots of email has been sent over the Internet as plain-old-text when it should have been encrypted.

Most of the software that we use everyday is "just good enough software." This type of software is fine when using it on a personal computer that is not connected to the Internet; but, this code becomes "just bad enough software" when the personal computer is connected to the Internet (and a whole wide world of crackers/criminals).

Don Henley, back in 01989, wrote a song titled "Gimme What You Got" that contained the lyric: "A man with a briefcase can steal more money than any man with a gun." Henley should modernize his lyric by adding the line "And a cracker with a high-speed Internet connection can steal more money than any man with a briefcase."

Although they will eventually become a computing relic, passwords still play a critical role in our computing world. During 01999, I created a webpage about passwords.

Computing::Computer Literacy Goes Well Beyond Email
I posted the following to my AzFoo blog at AzCentral.com.

"Obama mocks McCain as computer illiterate" was an AP headline on 12 September 02008.

"He admits he still doesn't know how to use a computer, can't send an e-mail, [...goes off topic...]," said Obama about McCain.

In a nutshell: Being able to use email doesn't define computer literacy. My guess would be that Obama is only slightly less computer illiterate than McCain.

Donald Knuth--one the world's greatest living Computer Scientist--doesn't use email.

"I have been a happy man ever since January 1, 1990, when I no longer had an email address. I'd used email since about 1975, and it seems to me that 15 years of email is plenty for one lifetime," wrote Donald Knuth.

Note: Knuth doesn't use a hyphen when he writes the word email.

"Thus it's high time for everybody to stop using the archaic spelling e-mail. Think of how many keystrokes you will save in your lifetime if you stop now! The form email has been well established in England for several years, so I am amazed to see Americans being overly conservative in this regard."--Donald Knuth.

By the way... Knuth has an amazing collection of diamond-shaped road signs.

In a nutshell: Most of today's political leaders are computer illiterates.

Computing::Blue Waters Coming in 2011
Kudos to the National Center for Supercomputing Applications (NCSA) at University of Illinois at Urbana-Champaign for partnering with IBM to "build the world's first sustained petascale computational system." The supercomputer will be named "Blue Waters" and it is scheduled to be online in 2011.

Blue Waters, which is supported by a $208 million NSF grant, will have "more than a petabyte of memory and more than 10 petabytes of disk storage." By the way, one petabyte is a million billion bytes (i.e. 1,000,000,000,000,000 bytes).

   "Blue Waters will be an unrivaled national asset that will 
    have a powerful impact on both science and society," said 
    Thom Dunning NCSA director and a professor of chemistry at 
    Illinois in a release.  "Scientists around the country-simulating 
    new medicines or materials, the weather, disease outbreaks, or 
    complex engineered systems like power plants and aircraft-are 
    poised to make discoveries that we can only begin to imagine."

[Extra] [side-bar] It was at the NCSA where Andreessen and Bina created the Mosaic web browser (circa 1993). Mosaic, which eventually became Netscape, played a key role in increasing the popularity of the World Wide Web. In 2003, NCSA created the PlayStation 2 Cluster to support scientific computing. Today, a PlayStation 3 Cluster is playing a key role in the Folding@home project.

GDT::Gerald.Thurman.Name Lives
The dot-name domain names have never caught on, but that didn't stop me from renewing the Gerald.Thurman.name domain name on 2 September 2008. I registered the domain name for the first time on 4 September 2003 and I've had it ever since. I don't know how many Gerald Thurmans there are in the world, but only one can have the Gerald.Thurman.name domain name and that's me.

Computing::Google Chrome; Open Source; Web Searches
Google practiced its motto of "launch early and iterate" when the company released a beta-version of the Chrome web browser. Currently, Chrome runs only on Windows, but that will change in future iterations of the browser.

Chrome is Open Source software, which is yet more confirmation that Free Software and Open Source are major tools in our 21st century computing world.

"We hope to collaborate with the entire community to help drive the web forward," said Google in a press release.

Kudos to Google!

"Super interactive browser that sits atop a super-fast connection--now interesting things will happen over the next 5-10 years," said Marc Andreessen. It has been 14 years since Andreessen created the Mosaic Netscape web browser.

Kudos to Andreessen for thinking near term (02013-0218). 02013 is in the early part of the second decade of the 21st century.

I enjoyed the following quote from Google co-founder Larry Page: "You only have 24 hours a day, and we would like you to do more searches. If the browser runs well, then you will do more searches."

According to SearchEngineWatch.com, Google executed almost 62 percent of the 12 billion searches conducted during July 02008.

What's going to happen to the web search counter when the majority of college students get back to school and start pounding away on all those high-speed-Internet-connected school computers?

Computing::Digital Divide Alive and Well in Arizona
I posted the following Computing::Bit to my AzFoo blog at AzCentral.com on 28 August 2008.

Kudos to the Arizona Republic for Sunday's article "Lagging Web access puts Arizona kids behind." Reading the article made it difficult to believe that we're nearing the end of the decade zero of the 21st century.

In a nutshell, Arizona is suffering from a problem that has been a problem world-wide ever since the proliferation of the personal computer -- the Digital Divide.

I'm stating the obvious, but at Scottsdale Community College I have seen with my own eyes that the digital divide can result in a learning divide. Students that have computers and high-speed Internet connections where they live have more learning resources readily available to them than those who don't.

I am five-nines confident that if every person had a computer with a high-speed Internet connection and an appropriate level of computer literacy, our rate of learning would be significantly higher.

Arizona's "digital divide" makes it the Grand Canyon state in more ways than one.

Math::Factorial Program Added to the MBNA
MathBabbler added a C++ factorial program (function) that he had laying around to the MBNA (MathBabbler Number Analyst).

The code was compiled with gcc on a machine where the size of the floating-point data type long double is 16-bytes. The maximum value that can be stored in a variable defined to be type long double is 1.18973e+4932.

MathBabbler played around and discovered that the largest number the factorial program can process is 1754.

   1000! is 4.02387e+2567
   1200! is 6.35079e+3175
   1400! is 3.46063e+3798

GDT::Arizona/Alaska Connections
I posted the following to my AzFoo blog at AzCentral.com on 29 August 2008.

   How cool... connections between Arizona and Alaska 
   (states 48 and 49, respectively).

   On 1 July 02008, Dr. Jan Gehler became President of Arizona-based 
   Scottsdale Community College (SCC).  Prior to joining SCC, Gehler 
   was Dean of the Community and Technical College at the University 
   of Alaska at Anchorage.

   On 29 August 02008, Arizona Senator John McCain announced that 
   Alaska Gov. Sarah Palin is going to be the next Vice President 
   of the United States.

MOTD::First Posting For Fall 2008
This is the first posting to the 34th edition of the MOTD (Message Of The Day). I've been doing the MOTD since the fall of 1997.

Computing::Peter Denning on Computational Thinking
Peter Denning did an excellent job describing "computational thinking" in an ACM "IT Profession Viewpoint." Denning's essay was sub-titled: "The choir of engineers, mathematicians, and scientists who make up the bulk of our field better represents computing than the solo voice of the programmer."

Denning's essay had to do with CS enrollments and that the "CS = programming" myth is alive and well.

In his essay, Denning speaks in six voices of computing professionals: the programmer, the user, the computational thinker, the mathematician, the engineer and the scientist. He also speaks in a seventh voice--the catalog. He calls the seventh voice the "last voice" because "it may be the last voice consulted by young people before deciding against computing as a major."

The six professional voices all start the same way... "I love programming"... "I love using computers"... "I love problem solving"... "I love mathematics"... "I love building things"... and "I love discovering new things about nature." The last voice, which is dull and boring, says nothing about "love."

Here are quotes from Peter Denning's description of computational thinking.

   "I love problem solving.  Not just any old problem solving,
    but problem solving using algorithms. [...] Sometimes I
    implement those solutions myself, and sometimes I let my
    friends the programmers do that. [...] I'm all about thought.
    One of my greatest successes is to get politicians to think
    that through their laws they are programmers of national
    social systems.  I've got economists thinking they can
    program the economy with right policies.  Perhaps my
    greatest triumph is to get people everywhere to think
    their brains are computers and that everything they
    do and say is simply an output."

Later in the same issue of the Communications of the ACM in which Denning's "IT Profession Viewpoint" was published, there was an "Education Viewpoint" titled and "Paving the Way for Computational Thinking." The sub-title of the "Education Viewpoint" was: "Drawing on methods from diverse disciplines--including computer science, education, sociology, and psychology--to improve computing education."

Math::Functionary is Not a Math Dictionary
The front-page of the Arizona Republic's Valley and State section on Friday, 22 August 2008, had a story headlined: "Flake says neo-Nazi tie hurts GOP."

The Republic's story contained the following phrase: "[...] to demand removal of a minor functionary on the lowest rung of the party's ladder."

Functionary? Sounds like a math dictionary containing definitions for function related terms. For example: What's the definition for "practical domain"? Hmmm... hold on while I look it up in my functionary.

However, functionary is not a math dictionary--it's a noun.

   functionary. (2008). In Merriam-Webster Online Dictionary.
   Retrieved August 22, 2008, from 
   http://www.merriam-webster.com/dictionary/functionary
   "1: one who serves in a certain function
    2: one holding office in a government or political party"

All of us are probably functionaries whether we like it or not. For example, MathBabbler is a computing functionary because computing is his profession. The "neo-Nazi" mentioned in the Arizona Republic's article is a political functionary.
