• matlab's fortran's format equivalents

  - by ldigas

  What would be matlab's equivalent of write(1,'("Speed, resistance, power",3f8.2)')(a(i),i=1,3) I've tried a = [10. 20. 200.] fprintf(unit1,'a = 3%8.1e',a) but I'm still having trouble with it (the whole matlab output formatting thing). Edit for Kenny: for the values of a as given above, it would give (in a new row): Speed, resistance, power 10.00 20.00 200.00

• When is better to use a parser such as ANTLR vs. writing your own parsing code?

  - by ViralShah

  I need to parse a simple DSL which looks like this: funcA Type1 a (funcB Type1 b) ReturnType c As I have no experience with grammer parsing tools, I thought it would be quicker to write a basic parser myself (in Java). Would it be better, even for a simple DSL, for me to use something like ANTLR and construct a proper grammer definition?

• Change the key being pressed with C#

  - by Benny

  Hey, I'm trying to write a program in C# that will track the pressing of certain keys (using a keyboard hook), and send different ones instead. For instance, when I press the A key it will instead send the Q key. I used http://www.codeproject.com/KB/cs/CSLLKeyboardHook.aspx this for my hooks and tried to use the SendKeys function, but I get an exception about the garbage collector destroying some object inside the hook class.

• Determining if types alias to the same underlying type in C++

  - by emchristiansen

  I'd like to write a templated function which changes its behavior depending on template class types passed in. To do this, I'd like to determine the type passed in. For example, something like this: template <class T> void foo() { if (T == int) { // Sadly, this sort of comparison doesn't work printf("Template parameter was int\n"); } else if (T == char) { printf("Template parameter was char\n"); } } Is this possible?

• Graph generation on iPhone

  - by Parrots

  Anyone have experience with drawing graphs on the iPhone? Looks like GraphKit isn't an option, so it's up to the programmer to either write his own library (using OpenGL, I guess), or an existing library. I can't seem to find any libraries that are confirmed to work on the iPhone. If you've written your own how did you go about it (opengl, quartz, etc), or if you used a library which one?

• R equivalent of SELECT DISTINCT on two or more fields/variables

  - by wahalulu

  Say I have a dataframe df with two or more columns, is there an easy way to use unique() or other R function to create a subset of unique combinations of two or more columns? I know I can use sqldf() and write an easy "SELECT DISTINCT var1, var2, ... varN" query, but I am looking for an R way of doing this. It occurred to me to try ftable coerced to a dataframe and use the field names, but I also get the cross tabulations of combinations that don't exist in the dataset: uniques <- as.data.frame(ftable(df$var1, df$var2))
