From the article:

This would seem like a good reason not to use them, even in a government project.

Having said that, I have found that paying a professional has always been a worthwhile investment. I have a masters degree in mathematics, so it's not a question of the calculations, but my accountant knows things about tax law that I don't, and keeps me from getting audited while getting me the best refunds that the law allows.

Africa also has some of the richest soil in the world.

One of my favorite stories about my visit to Zaire (now Congo), is when we were taken to see the air strip.

We were visiting a little mission hospital on the shore of Lake Tanganyika, near Uvira, and one day they said that we were going to walk out to the air strip. They didn't get many planes in, and each time they were expecting a plane in, they'd send out some folks to make sure that it was clear.

But this was just after the rainy season, and there hadn't been a plane for almost two months, and we couldn't find the air strip at first because there were full-sized trees growing all over it. We found the markers, and it was clear where it had been, but it looked like a full-grown forest.

As others have mentioned, saying that Africa has some of the poorest soil in the world is absurd. So does the USA. It's a little like saying "Australia has some of the youngest people in the world."

Certainly not. Open Source is nothing if not self-defined. I get to define when my project is successful, and quality might be that definition, in my particular case. Fortunately, quality often leads to usage. But even when it doesn't, it's a worthwhile goal.

The focus on dramatic stories is misplaced. The simple loss of dignity in traveling should be sufficient. I'm tired of being assumed to be a criminal when I travel.

This is a really dangerous distinction. Crime is crime. Politically motivated crime is - what? Terrorism? I don't like where this is going.

Dress professionally. Keep regular hours. Work as though you were at work.

That's not true. In politics, if something fails, we sneak it into another bill a few months later.
