Hi guys, Is there a way of converting a hash table into a list of (key,pair) values in OCaml? I'm aware that, given a hash table ht we can do BatList.of_enum (BatHashtbl.enum ht) using the batteries library. This would convert the table to an enumeration and then convert the enum to a list. But I'm looking for a solution that doesn'...

I've got a list consisting of smaller lists inside of it, each list consisting of 2 items: [[a,1],[b,2],[c,3]] I'm using a function called take(1,L,R) to take the first item from list L and return the item R. The code for the take function is here: take(0,X,X). take(N,[H|T],[H|R]):- N>0, M is N-1, take(M,T,R). At t...

I have a series of checkboxes, and everything works except their default behavior has been altered unintentionally so I can no longer check them which is odd since the reason I was using this bit of jquery was to highlight the li around them when they got checked in the first place. Any ideas? //Tag cloud $(".tag-cloud li").toggle( f...

I've just started Android development with Eclipse, so I've been going through all the "Hello" tutorials on the Android Developers site. I have come unstuck, however, on the List View tutorial. I have tried many times to correct the problems, but I am inexperienced and whatever I do doesn't seem to work. I have copied and pasted the code...
I'm obviously missing something here. Same project I've been working on for a number of days. Stepping through it bit by bit, seemed to be working fine. I added in a portion of the main() function to actually create the comparison lists, and suddenly starts throwing out cannot pop from empty list error at me, even through a print functio...
Hello. This is my second quick-and-silly question about LISP, but I am kind of stuck. I need to access all the nodes in a list with several levels. I need something like: >> (get-symbols '(A (B (C D) E ))) (A B C D E) I don't care about the order. How would you do that? I prefer code intuitivity rather than efficency. Thanks ...

What is the fastest (or most "Pythonic") way to convert x = [False, False, True, True] into 12? (If there is such a way.) What if x were instead a numpy.array of bools? Is there a special command for that? I have a large m-by-n array of booleans, where each n-element row represents a single low-dimensional hash of a high-dimensiona...
