Workflow for statistical analysis and report writing
...orts every time. I built a Sweave template for the reports (which takes a bit of work). But once the work is done, I have a separate R script that lets me point out the new data.

}
}
Then what happens when you call this supposedly thread-safe bit of code from multiple threads? Will it always work OK?
if (!mySafeDictionary.ContainsKey(someKey))
{
mySafeDictionary.Add(someKey, someValue);
}
The simple answer is no. At some point the Add method will throw an e...
Why can't radio buttons be “readonly”?
...adio button just set the value of the hidden field. Ether way, it's just a bit more cumbersome than I'd like a radiobutton to be. Your second solution, although I don't doubt it works, sounds like a really ugly hack. So I guess the javascript solution is the only one that meets my criteria. I'll g...

If you're using C# 3 and you have a distinct set of keys, you can make this even neater:
var currentViews = new Dictionary<string, object&g...
How to improve performance of ngRepeat over a huge dataset (angular.js)?
... sum it up as: don't just limit the count of rendered DOM elements to an arbitrary (but still high) paginated number like 50, 100, 500... instead, limit only to as many elements as the user can see.
If you do something like what's commonly known as "infinite scrolling", you're reducing the initial...
