A few more steps toward on-line education

drawing: Krzysztof Szymański

Education may be the Internet’s killer app.

I’m very excited to see that the Internet may allow us to unlock the doors to education. Salman Khan’s Khan Academy took a giant step forward, and now some prestigious universities are following. It’s just in time, because the cost of higher education is out of control. Why?

Salman Khan, at a recent Wall Street Journal Executive Conference (The 19 minute video is worth watching) explained why top universities charge $60,000 per year:

There is a fundamental disconnect happening between the providers of education and the consumers of education. If you ask universities what they are charging the $60,000 for, they’ll say, “Look at our research facilities. Look at our faculty. Look at the labs and everything else.” And then if you ask the parents and the students why they are taking on $60,000 of debt, they’ll say, “Well, I need the credential. I need a job.”

So one party thinks they’re selling a very kind of an enriching experience, and the other one thinks that they’re buying a credential. And if you ask the universities what percentages of your costs are “credentialing,” they say oh, maybe 5% to 10%. And so I think there’s an opportunity if we could decouple those things—if the credentialing part could happen for significantly less.

John Hennessy, president of Stanford University, replied:

We put some of this stuff online and then all of a sudden we got 100,000 students around the world signed up. We’ve learned a bunch of things. One of the phenomenal things we saw in our experiment was how quickly the community would answer questions when students in the class posed them. What I told my colleagues is there’s a tsunami coming. I can’t tell you exactly how it’s going to break, but my goal is to try to surf it, not to just stand there.

Now Stanford’s on-line experiment (initiated by Google’s Sebastian Thrun, not Sanford’s administration) is joined by some heavy hitters:

• In May, Harvard and MIT announced edX, slated to offer full-blown online courses this Fall, apparently at no cost. In the announcement of edX, its president claims “This is the biggest change in education since the invention of the printing press”. Credentials? “Certificates of mastery will be available for those who are motivated and able to demonstrate their knowledge of the course material.”
• Coursera, partnering with Stanford, the University of Michigan, Princeton, and University of Pennsylvania, will offer courses at no cost, but will charge money for still undefined additional services. (Do these include accredited degrees? I have no idea.).
• Udacity has grown out of Stanford and is beginning to offer free online courses. It’s headed by Sebastian Thrun (who led Google’s driverless car project). In a Wall Street Journal interview, Mr. Thrun says “The dialogue always focuses on what’s going to happen to the institutions. I’m totally siding with the students.”

Do you remember the effect that email had on hierarchies? It flattened them. Maybe e-education will have the same effect. Victor Hugo (1802-1885) said it best: “All the forces in the world are not so powerful as an idea whose time has come.”

Charlie Rose scores a hat trick

The founders of Netflix, Web-based training company, and author of In the (Google-)Plex . . . all interviewed.

Yes, I’m shilling for Charlie Rose again.

1. Reed Hastings founded Netflix in 1997 and is its CEO. He reports that Netflix continues to move away from mail delivery of plastic DVD discs to on-demand streaming of video via the Internet. They’re also slowly moving toward content production — not just delivery. He reports that they have 23.4 million subscribers, and a 70 percent growth rate(!).

Mr. Hastings claims that Microsoft’s Windows 7 is wonderful, and is now the best selling operating system ever. I take this with a large grain of salt, since he sits on Microsoft’s board of directors, and many of those copies that filled up channel pipelines aren’t actually being used.

Watch this interview

2. Salman Khan is focusing on providing web-based training. Until now, he’s working outside traditional academia, but wants his Khan Academy training courses to gain the same standing as more traditional teaching methods. I liked what he had to say and think that he’s moving in the right direction regarding the need for easy to understand instruction even for complex subjects. (See my recent article, It’s time to rationalize school curricula.) Bill Gates told Parade Magazine that he uses Khan Academy when he homeschools his own children.

Mr. Khan views Khan Academy as filling in gaps in students’ understanding.

Watch this interview.

3. Steven Levy seems like an old friend. (I’ve never met him; I’ve just read his books and articles.) His 1980s book, Hackers, is a classic. His most recent book, In The Plex: How Google Thinks, Works, and Shapes Our Lives is about Google. This is a broad subject: Google’s annual revenue is 30 billion dollars — all from advertising(!). He reports that Larry Page’s recent return to the CEO position is intended to continue innovation. Google continues to allow its employees to use 20 percent of their time (one day per week) to pursue subjects that interest them — not necessarily Google. Larry and Sergey are both products of Montessori schooling, which encourages original thought — and according to Mr. Levy they both prize creativity within Google. The job ahead for Larry Page is to keep Google agile and innovative, even though it’s now a huge company.

Charlie asked Mr. Levy about Google’s ambivalent relationship with China, and its policies regarding user privacy: this is fascinating.

Watch this interview.

I recommend all three of these interviews. (All 3 images are from http://charlierose.com.)

Gordon Welchman, Codebreaker

Gordon Welchman was an Englishman who, while working on decoding German messages at Bletchley Park during World War II, invented traffic analysis. His idea was that even if one couldn’t decipher message contents, just tabulating who messaged whom, when, and how frequently, lent knowledge about the enemy.

After the war, he emigrated to America, where he became an American citizen and taught the first computer course at M.I.T. He worked for Remington Rand and eventually for the MITRE Corporation, where he enhanced traffic analysis technology and helped develop C³ (Command, Control, and Communication) systems.

Following the publication of his book The Hut Six Story in 1982, which detailed the work of his Hut Six group at Bletchley Park, his security clearance was revoked. This killed his career in intelligence.

Today we call the information that surrounds a message “metadata”.

Snowboarding NYC, Jan 2016

Well, both snowboarding and skiing. Reminds me of water skiing. The middle east coast states received buckets of snow this weekend and these New Yorkers made the best of it. Yes, that looks like Broadway in Times Square.

Hillary Clinton-approved email server

I love this parody.  It’s a humorous advertisement for your own mail server:

Do you run a government agency but hate complying with the law?  Then you need DC Matic, the Hillary Clinton-approved email server!

What’s Hillary hiding?  Classified emails?  Sure.  Evidence of her negligence in Benghazi that led to the murders of US citizens?  Of course.  Security breaches via assistant Huma Abedin’s Muslim Brotherhood connections?  Probably.  No, the ticking time bomb in this server is bribery.  Maybe treason as well.  She’s hiding written evidence of her deals that traded State Department help in exchange for large donations to the Clinton Foundation and large fees for speaking engagements by Bill Clinton.

Putney Swope and Barack Obama

Today’s laughably corrupt Obama regime is life imitating art. Which art? Cinema. Whacked-out cinema. Farce. Namely, 1969’s Putney Swope:

Both Swope and Obama were elected to office by fools who suffer from chronic white guilt.

In 1969, Putney Swope announced:

The changes I’m gonna make will be minimal. I’m not gonna rock the boat. Rockin’ the boat’s a drag. What you do is sink the boat.

In 2008, Barack Obama bragged:

. . . we are five days away from fundamentally transforming the United States of America.

Mr. Obama is trying to transform America, alright. Transform it from a prosperous capitalist economy governed by a constitutional republic to a bankrupt socialist economy governed by a corrupt tyrannical dictatorship. Barack is following Putney’s credo, “What you do is sink the boat.”

YouTube subtitle humor

Here’s a funny video that’s supposedly an Iranian negotiator recounting the stupidity of Messrs Obama and Kerry:

The sardonic subtitles were added by Madison McQueen. (She apparently is the granddaughter of actor Steve McQueen.)

The best line:

I’ve had tougher negotiations over a falafel sandwich!

I first saw this sort of humor in a video clip taken from a biography of Hitler: United broke Hitler’s guitar, too!.

I like this sort of humorous subtitling. And I like its message: Obama and Kerry are fools.

Wanna see jitterbug? Wanna hear rock & roll?

Check out this video:

The tune, “Slow Down”, is performed on piano and sung by its composer, Larry Williams. He was from New Orleans (of course). The tune, ringing with ninth chords, was released on disc in 1958. I think that the dancers are from a 1950s Hollywood rock & roll movie. Larry also composed Dizzy Miss Lizzy, Bad Boy, and Bony Moronie — classic rock tunes, all. He was born in 1935 and died on this date, January 7, in 1980.

In the mid-1950s, Williams inherited star billing from Little Richard (who’d forsaken rock and roll for religion) at New Orleans’ record label Specialty Records.

While Williams was alive, the Beatles paid their respects by admirably covering Larry’s Dizzy Miss Lizzy, Slow Down, and Bad Boy. I’m amazed that Larry Williams isn’t in the Rock and Roll Hall of Fame.

Extra credit assignment: Compare and contrast the Beatles’ cover of Slow Down with Larry Williams’ original. This clip includes the fab four wailing in Liverpool’s Cavern Club: (If YouTube has taken down this video clip, you can hear the same recording with groovy rock and roll clips (sorry — requires Flash) from 1950s America and early Beatles. Sorry for the Flash format.)

Joni Mitchell, Jaco Pastorius, et al on YouTube

I’m delighted to discover that the video of Joni Mitchell’s classic Shadows and Light concert (1980) can be viewed in full (1h 13m) on YouTube. Supporting players are Jaco Pastorius on bass, Pat Metheny on guitar, Michael Brecker on sax, Don Alias on drums, Lyle Mays on keyboards, and The Persuasions. It’s among my favorite videos of a concert performance.

Jaco Pastorius

Jaco was a Fort Lauderdale kid who began playing in rock bands around town in a variety of clubs: She, The 4 O’Clock CLub, The Village Zoo, The Flying Machine, The Button, Bachelors III, Ocean Mist . . . When I first heard Jaco in the early 1970s, he was playing bass for straight-ahead local rock bands. He graduated to more jazz- and fusion- related music and put his unique fretless Fender bass stamp on Weather Report. I’ve heard bass players tell me that they tried to imitate Jaco’s technique, but gave up trying; they claim that Jaco changed what it meant to play electric bass guitar. Jaco’s friend Pat Metheny, who plays a beautiful lead guitar in this concert, is a University of Miami music school graduate.

Jaco seemed to still have his act together when he played this concert. Wikipedia has a good Jaco biography. He had a rapid rise to the top followed by a quick ride back down again. I had musician friends c 1984-87 who were torn up watching their friend Jaco dismantle his life. This Warner Brothers recording artist and Down Beat Hall of Fame member was sleeping on park benches and shooting baskets in a local public park.

Michael Brecker and Don Alias died a few years ago.

This is a classic performance by master musicians who were at the top of their games. Too bad it couldn’t last forever.

FCC may fine NBC for Miley Cyrus “Bangerz” show

According to Rolling Stone magazine, the FCC is considering disciplining NBC for airing an indecent performance on July 6, Miley Cyrus’ “Bangerz Tour”. I watched it. It was provocative, but artful. Bertolt Brecht would have loved the production: live dancers against rear-projection oversized animation with creative costumes and lighting. I loved it. Some of the images, such as Miley riding a giant “Mr. Wiener”, were sexually suggestive.

The concert (recorded in Barcelona) reminded me of Madonna’s shows twenty-five years ago. Both performers have acceptable contralto voices, energetic dance skills, and assemble exciting Brechtian spectacles. I love the costuming and choreopgraphy. Shocking? “Bangerz” pushed the limits on prime-time American TV, I suppose. But that week on television, the atrocious performance by the Brazilian football team was truly shocking.

I’d prefer that the FCC take no action on this. They have enough serious issues on their plate already. Censoring art is, in my opinion, a slippery slope for any government agency . . . and I think that this production can be labeled “art”. Here’s the full show (862MB H264 1h 25m mp4 video file, 720 x 404 pixel) for download or streaming:

You’ll need a fast Internet connection to smoothly stream this. You might be better to download the file and then play it locally with a good video player such as VLC.

Is it Miley’s performance or just modern low distortion recording technique that for the first time makes John Lennon’s “Lucy in the Sky with Diamonds” lyrics (at 44m 35s) sound so . . . so . . . clear, logical, and complete?

What do you think?

How are modern integrated circuits manufactured?

I’ve worked with integrated circuits (I.C.s) since the 1960s, but haven’t been involved in their manufacture — only their application.

Today’s integrated circuit manufacture is a high stakes capital intensive business whose players use trade secrets to maintain their market advantage. I’ve never been inside an I.C. “fab” (factory), so it was a treat to find an hour-long presentation by an industry manufacturing engineer on YouTube. The technologies used at nano dimensions are mind-boggling.

Here’s the excellent presentation, in full:

The speaker mentions that lithographic imaging of the mask is now being done at 193 nanometer (nm). As you can see, we’re well above visible light and on our way to x-rays(!). Here’s the electromagnetic spectrum in that region:

The presentation is aimed at the layperson and is filled with surprises. For instance, one gigabyte of semiconductor memory can be produced on a flat substrate within the diameter of a human hair. I give it two (gloved) thumbs up.

How to program, lesson 1

Good programming advice:

Begin at the beginning and go on till you come to the end: then stop. — Lewis Carroll

Infinity

Two things are infinite: the universe and human stupidity; and I’m not sure about the universe. — Albert Einstein

Steve & Jimi on choices

Your time is limited, so don’t waste it living someone else’s life. Don’t be trapped by dogma – which is living with the results of other people’s thinking. Don’t let the noise of others’ opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary. — Steve Jobs

I’m the one that’s gonna have to die when it’s time for me to die, so let me live my life the way I want to. — Jimi Hendrix

Albert Einstein liked simple language.

If you can’t explain it to a six year old, you don’t understand it yourself.

If you can’t explain it simply, you don’t understand it well enough.

— Albert Einstein

Both aphorisms have been attributed to Dr. Einstein. I mentioned in Plain English that,

In my experience, the best scientists and engineers explain complex concepts by using simple words in simple sentences. Dolts, on the other hand, make everything sound complicated.

I’m glad that Dr. Einstein agreed. (After watching his video biography, I now think of him as “Uncle Albert”.)

Nothing ventured, nothing gained.

Those who dare, risk failure.
Those who don’t, ensure it.

Walt Mossberg, WSJ Tech Critic

I just listened to an excellent interview with Walt Mossberg, who since 1991 wrote a weekly computer industry column for the Wall Street Journal. Walt’s now retired. Leo Laporte, an industry podcaster, coaxes some great stories from Mr. Mossberg. 

Walt’s perspective was always that of a user — not a tech freak. Most industry reporters are techies who don’t appreciate that most of us don’t care about the inner workings and secret mechanisms of computers.

Walt speaks a bit about his long relationships with both Steve Jobs and Bill Gates. (Walt sat in the passenger seat as Gates, frustrated by traffic, drove his Lexus for miles on the road’s shoulder.)

It’s a pleasant and informative hour-long conversation.

ABBA reconsidered

In the 1970s and early 1980s, I loved ABBA’s music. I was pleased to discover this recent critique, in both spoken and written form. I didn’t realize that ABBA were considered politically incorrect in their home country.

The world according to ABBA (audio clip)

Intelligent Life magazine‘s Matthew Sweet observes that ABBA’s songs progressed from naiveté through sophistication to melancholy. As Matthew says, “Many of their songs are about accepting the failure of relationships”.

Here’s the companion article, Thank You for the Music, by Matthew Sweet, from a recent issue of Intelligent Life. Both the article and the audio clip stem from his visit to Stockholm’s ABBA Museum.

Taking Back the English Language

I listened to KERA’s Krys Boyd interview author Steven Pinker about one of my favorite topics: plain English. Mr. Pinker authored The Sense of Style: The Thinking Person’s Guide to Writing in the 21st Century. He claims that education often interferes with a person’s clarity. He refers to this wordy English dialect as academese, which is similar to corporate hack boilerplate.

I agree. Most academic papers are terribly written, as is the text in many corporate websites.

Both dialects employ the passive voice and zombie nouns: nouns created from verbs. For example, instead of appearing, there is an appearance. Instead of cancelling, there is a cancellation.

Mr. Pinker closes with the “prime directive” of Strunk and White’s The Elements of Style:

Omit needless words.

Why not a movie about Ada?

Now that not just one, but two movies (Breaking The Code and The Imitation Game) have been produced about Alan Turing, it’s time we had a movie about Ada Lovelace. She seems to have possessed an unusual combination of precise reasoning and imagination, strong will, and feminine charm. Plus, she was in the middle of a tug o war between her feuding parents, poet Lord Byron and his wife Anne Isabella.

Why is Ada important? She’s acknowledged to be the first computer programmer (c 1840!). Like Mozart and Turing, her life was tragically cut short at a young age. I propose this biopic today because it’s Ada Lovelace Day!

While verifying quotation authenticity, I found a useful — and delightful — website, quoteinvestigator.com, which tries to chase down the origins of quotations.

New and Improved Method

If you’re using Windows 7 or 8.1, and you’re sick of being nagged by Microsoft’s pop-up to upgrade to Windows 10, go to the Ultimate Outsider website and download and install their GWX Control Panel. It’s received rave reviews. Cost: gratis. Here’s the full description.

Microsoft Strikes Again – How to NOT Upgrade to Windows 10

 

Update, April 3, 2016: Steve Gibson, founder of GRC (Gibson Research Corp), has written a great little freeware utility that also blocks upgrades to Windows 10. Steve writes most of his code in assembler, so his utilities are tiny. He calls this newest utility Never10. He’s created a page dedicated to Never10, where you may download it for free. It’s only 81 kilobyes in size and doesn’t require installation on your Windows PC.  You need just run it once to turn off upgrades to Windows 10, and run it again to allow upgrades to Windows 10. Short and sweet, it’s just what the doctor ordered.

Save time when installing application programs on a PC.

Installing two or more application programs on a PC can chew up your time as you wade through web pages, download prompts that don’t always work, and questions and answers. Now ninite.com (http://ninite.com/) does this tedious work for you. I’ve tried it on a few PCs and it’s worked flawlessly. Install everything in one easy step on your brand-new Windows 7 PC!
