“This is Apollo 13 – Cambridge, we have a problem.”

by Prof. Barry Dwolatzky

MIT ImageAt 9:08pm on April 13 1970, astronaut James A. Lovell Jr, commander of Apollo 13, spoke the now famous words, “Houston, we have a problem.” If Lee Harvey Oswald hadn’t shot President John F. Kennedy in Dallas on November 22 1963, Lovell would have informed Cambridge, Massachusetts, rather than Houston, Texas, of his “problem”. Continue reading

Is it time to re-establish Software Engineering on firmer foundations?

by Prof Barry Dwolatzky

Software Methods are like a fashion show


Software Engineer #1:  What methodology are you using these days?

Software Engineer #2:  We’re into Lean in a big way …. with a few XP practices thrown into the mix. We were very into Scrum last year, but then I read this amazing book and really got hooked on Lean.


SE #1: I remember the arguments we used to have a few years ago. You tried to convince me that Agile was a recipe for disaster. I think you were very keen on RUP at the time.

SE #2: That’s right. I was very young and immature then. I’ve got a much deeper understanding now of how software development really works, and I have absolutely no doubt that Lean and Kanban have all the answers for me.

Its 2012 and Africa is Rising

by Prof Barry Dwolatzky


Welcome back to my blog. It has a fresh look and I hope you will follow me and share your comments in the year ahead.





In May 2000 the Economist magazine labelled Africa “The hopeless continent”. In December 2011 the same magazine featured an article entitled “The hopeful continent: Africa Rising”  (View the article) . This dramatic U-turn by the Economist put a smile on my face. I’ve never doubted the incredible potential of the continent on which I live. Did you? Now we are seeing that potential being translated into high growth rates and thriving economies.

Imagine Cup 2011 has come to an end.  It was a truly incredible experience to be part of it. The award ceremony was held in the famous Koch Theatre at New York’s Lincoln Centre. Being in that theatre surrounded by the energy and enthusiasm flowing from 400 excited students was truly amazing. Continue reading

I’m in Geek’s Heaven

Steve Ballmer - CEO of Microsoft - opens Imagine Cup 2011 in NYC

Steve Ballmer - CEO of Microsoft - opens Imagine Cup 2011 in NYC

For those of you who don’t know about it, the Microsoft Imagine Cup is a bit of a “geek show”. University students – working in small groups – develop software applications and then compete for prizes. Microsoft runs national competitions, the winners of which are entered into the World Finals.

Over the past few years I’ve been involved in Imagine Cup South Africa as a judge. The competition always attracts a good cross-section of socially awkward technology obsessive South African youth. Race, religion, social background, gender – none of this matters. They all share a common “geek-ness”. From the SA competition we have always carefully selected the best team of local geeks and sent them off to compete in the World Finals. And here I am at the World Finals!!!

Over the past year 350,000 computer geeks from 183 countries have competed to represent their species at the Imagine Cup World Finals-  the “Computer Nerds World Cup”. And here they are at the 40-storey New York Marriott Marquis Hotel in Times Square. 124 competing teams from 40 countries together with 80 judges and 140 journalists. They come from every corner of the world. Most have never flown in an airplane. Some have never stepped onto an escalator … and yet they share something in common … a love for software technology.

Last night Steve Ballmer, CEO of Microsoft, opened the event. It’s the first time I’ve seen him live. If an alien from outer space came to earth looking for a good specimen of a “1970’s computer nerd” to send back home to a zoo in their distant planet, Steve Ballmer would be a wonderful choice. He is everything his generation (my generation?) represented – and more! When he announced that every contestant would receive an XBOX Kinect to take home with them, a cheer went up that must have been heard on the moon. (Thinking about it… the cheer wasn’t instantaneous .. It took about a minute for Ballmer’s announcement to be understood in 40 different languages.) In any other audience most people in the room would have been sitting there saying “what’s an XBOX Kinect, and what will I do with it?” My only regret is that I’m a judge and not a contestant.

There were also speeches from Jeffrey Sachs, Professor of Economics from Columbia University and special advisor to the UN on poverty alleviation, and from Dennis Crowley, co-founder of FourSquare [I admit to having to ask someone what "FourSquare" is]. Jeffrey Sachs was there because: (1) he was at nursery school with Steve Ballmer, and (2) the theme of Imagine Cup 2011 is “Imagine a world where technology helps solve the world’s toughest problems”. The challenges of the UN’s Millenium Development Goals are a particular focus for contestants.

Everywhere you look in the hotel there are groups of students dressed in their team t-shirts sitting around fiddling with devices – laptops, tablets, smart phones, fancy cameras, i-pods, etc. I can’t understand many of the conversations but I’m prepared to bet that its about the latest app, download or gadget.

Today I will be working hard. I’m a judge in the Software Design section. I will be listening to and marking presentations by the teams from Mexico, Taiwan, New Zealand, Australia and Greece. By the end of today the top 18 groups will go through to round 2, which we will judge tomorrow. The final is on Tuesday and the winners will be announced at a gala event at the Lincoln Centre.
