Great People, Great Teams

Bill Taylor’s post Great People Are Overrated on the HBR Blog Network has generated a lot of heat. His post was triggered by a statement Facebook CEO Mark Zukerburg made in an interview: “Someone who is exceptional in their role is not just a little better than someone who is pretty good,” he said. “They are 100 times better.” It emphasised what Marc Andreessen had told him: “Five great programmers can completely outperform 1,000 mediocre programmers.”

Bill Taylor does not agree with them. He goes on to make a case that a team of average performing individuals is better than high performing superstars, and concludes: “Most of business life isn't really a choice between one great person and 100 pretty good people, but if that is the choice, I'm not sure I'd make the same choice as Mark Zuckerberg — especially if those 100 pretty good people work great as a team.”

The last I saw, his post had received 272 comments, mostly from software practitioners, and the majority pilloried him.

The software devlopment crisis

Some blunt observations on the state of software development practices today, and a way out.

See other Tech-Ed 2011 videos here. Of particular interest to me were those tagged as Development Practices and Architecture.

Shrink a SQL Server database

When we create a SQL Server database, it is created with a full recovery model. This grows the transaction log (the .ldf file) with every transaction we make on the database. Usually the size of the transaction file is many times more than the .mdf file.

If not maintained, the transaction log would eventually fill all the disk space that is available to the physical log files.

In a development/ testing environment, when the data is not important, the transaction log is not important. It is a good idea to maintain the database with a simple recovery model.

Run this command in the Query Analyser to change the database to a Simple Recovery model:
ALTER DATABASE [<DatabaseName>] SET RECOVERY SIMPLE

Run this command to reduce the size of the .ldf file:
DBCC SHRINKDATABASE ([<DatabaseName>], 20)

When deploying the database to production, turn it back to the Full Recovery model:
ALTER DATABASE [<DatabaseName>] SET RECOVERY FULL

Replace <DatabaseName> with the actual name of the database.

Why I am bullish about India

A wonderful article by a friend that sums up the soul of India. Read it here.

Bugs!!

From Three Questions About Each Bug You Find
"..Do you sometimes fix a bug, and then find another bug related to the first or to the way you fixed it? When I fix a bug, I ask myself three questions to make sure I've thought carefully about its significance. You can use these questions to improve productivity and quality every time you think you've found and fixed a bug..."

Figure 1

Figure 1 is "The First 'Computer Bug' Moth found trapped between points at Relay # 70, Panel F, of the Mark II Aiken Relay Calculator while it was being tested at Harvard University, 9 September 1947. The operators affixed the moth to the computer log, with the entry: "First actual case of bug being found". They put out the word that they had "debugged" the machine, thus introducing the term "debugging a computer program". In 1988, the log, with the moth still taped by the entry, was in the Naval Surface Warfare Center Computer Museum at Dahlgren, Virginia, which erroneously dated it 9 September 1945. The Smithsonian Institute's National Museum of American History and other sources have the correct date of 9 September 1947 (Object ID: 1994.0191.01). The Harvard Mark II computer was not complete until the summer of 1947..." The First "Computer Bug"

A project in C++

My son graduates high school this year. One of the subjects he has opted for is Computer Science. The major focus of this course is to provide an understanding of object oriented programming (OOP) through C++.

As a requirement of this course he needs to submit a project that covers OOP, Data File Handling, and Data Structures. His school mandates that they use Turbo C++ 3.0.

The last few months I have been helping him with his project. Check it out here.

One good outcome is it has whetted my appetite for C++, and I intend to devote a large part of whatever spare time I have to it.

India: my pride, my shame

Today India completes 61 years as a Sovereign, Democratic and Republic state. We have been an independent nation for 64 years.

In this short span of time India has perfected the art of being corrupt. The CWG scam, the 2G scam, the Adarsh scam, $500 billion dollars of the country’s money stashed away in secret accounts abroad, bureaucrats discovered with Rs.300 crore stashed in suitcases at their home - these are the ones that are being talked about now. There are many from the past that we have forgotten. More importantly, we don’t remember anyone of any importance being ever punished.

With such a capacity to indulge in it, it is no surprise that corruption is so pervasive in our society, even soiling venerated institutions like the Armed Forces and the Supreme Court. We don’t need Transparency International’s studies to tell us we are rotten.

As a nation we need stalwarts in public life to look up to. The picture below defines stalwarts. We don’t have people of their vision, stature and influence anymore; however, we are desperate for them, gauging by our admiration for people like Dr. Abdul Kalam and Narayana Murthy. We need more and more people like them; we need their influence over us.

India has many good things going for it. Game-changing activities in the last 6, mostly in the last 3, decades in areas as varied as computerisation of railway reservations, telecom, low cost airlines, software and manufacturing, space research and technology, media, freeing the economy, strengthening the Election Commission, have taken our nation forward. These have been achieved by ordinary citizens doing extraordinary things without funfair, helped by some good thinking by those in government.

We need to do more: in infrastructure, providing quality education, improving agriculture, maintaining the unity without diluting the diversity and, our eternal bug bear, eradicating poverty. And there are many, with insight and zeal, already doing their bit in bringing about these changes. The scale is huge, given India’s diversity, size and population - and this all pervasive corruption makes the work tougher.

To be counted as an advanced nation, a nation truly respected, we must eradicate corruption from our midst.
