+American Red Cross... still not looking good, says +ProPublica in a response to a 5,000-word request for corrections. It's just funny how none of the 10 requests hold water.
The Red Cross' response comes months after our initial coverage, which we stand by.

+Jooyung Han Great! I'm sure you'll enjoy it.

Some advice: Don't wait for the deadline to apply. Do it soon to make sure you can get a spot. And write a clear letter explaining your background (e.g. your programming experience) and your interest in the course.

You can even mention you heard about it from me on Google+. I used to help with the course. :)

It's amazing to me how often I find the fallacious notion that expertise is the solution to avoiding seemingly trivial problems in software development. "Novices might make that mistake, but experts never would." That conveniently ignores the statistical reality of human fallibility added to the complexity of software.

1. Nobody is immune to mistakes.
2. Not all problems can be recognized as mistakes when the issue involves understanding a complex system of relationships.

Hooray for development tools that save me from myself.

The Type-Checker's Prayer

Our Type-Checker, which art in Haskell,
Hallowed be thy name.
Thy error comes.
It will be fixed
In code as it is in specification.
Give us this time our regular build.
And forgive us our trespasses,
As we forgive those who commit bugs before us.
And lead us not into untyped temptation,
But deliver us from exceptions.
For thine is the function,
And the module,
And the program,
For ever and ever.
Amen.

Well-kept, finely decorated environment with a convenient location for visiting Gold Reef City and other areas of southern Johannesburg. We are a couple who stayed one night over a weekend in July to go to the Gold Reef City Casino to see a show. The facilities were mostly comfortable. Our main complaint was that our deluxe double room was cold. The large bedroom was heated by one wall panel heater, which is not sufficient in the middle of the South African winter. Naturally, the bathroom floor and shower walls, being tile, were also cold, but this is not unusual for these kinds of houses. The owners were pleasant and helpful. I enjoyed talking to Eddie about cricket and to his friendly bird who visited my shoulder. The breakfast food was simple but fine. We do think the logistics of breakfast could be done better. There was some confusion about where to find items for drinking tea and eating cereal. Other parties had problems with their orders. Perhaps it would be better to arrange not just the time of breakfast but also the order the day before the meal. Overall, the experience was not too unpleasant. We might consider returning to Villa Lugano in the summertime.

The Rhino and Lion Nature Reserve is a nice place to go for a day trip to see some animals. It's kind of like a big zoo without all of the cages except for the big predators, who have large separate fenced areas for each group (brown lions, wild dogs, white lions, and cheetahs). However, the reserve is not so big that you won't see everything in a day. Unlike the Kruger National Park, you don't have to drive around for hours wondering if you'll see lions. On the other hand, the reserve is not as wild as the park, and much of that mystique is missing. Be sure to plan your trip in advance. Look up the lion feeding time and other events. These are important for getting the most out of your trip. If you have a utility vehicle or 4x4, definitely bring it. None of the roads are paved, and in some areas, e.g. the cheetahs, you will really struggle in a 2-door hatchback like we had. Overall, we enjoyed it. The staff was helpful. The food at the Boma Restaurant was pretty good. If you're staying in the Johannesburg/Pretoria area and want to see some wild animals, you should check out the Rhino and Lion Nature Reserve.

Fabulous! My fiancée (now wife) booked the honeymoon package at Elephant Hide in Knysna. First of all, let's put aside the fact that Knysna is gorgeous and completely worth your while. There's plenty to see and do. It's one of the rare places that I actually want to visit again. Let me just say that Elephant Hide is unbelievably fantastic. The people (Ryan, Mandy, Fish, and Eliot) are all very nice, helpful, and accommodating. The room was extremely comfortable. The view of the lagoon from our bedroom, bathroom, AND shower room was outstanding. The breakfast was delicious. And the location is very convenient while also being very quiet. Oh, and I'm told that the package price was pretty good, too. I would definitely recommend Elephant Hide to anyone. I'd also stay there again, myself.

A great place to learn about snakes and other creepy crawlies. James, our tour guide, was very knowledgeable and made it a fun and enjoyable experience. He even convinced my wife (who doesn't like snakes) to hold a Burmese python!
