Binary operations on Erlang binaries?
What's best way to do the following? Binary -> list -> binary seems unnecessary. binary_and(A, B) -> A2 = binary_to_list(A), B2 = binary_to_list(B), list_to_binary([U band V || {U, V} <- lists:zip(A2, B2)]). ...

Delete multiple nodes from a binary search tree
Hello, I have a binary search tree created in c. The problem is I can't find a efficient way to delete all the nodes with e.g. id>5. When I traverse the tree, if I delete a node, the recursion is getting error, because the structure is not the same. Is there any way, instead of using a helping stack to keep the data before delete them...

Erlang list comprehension with two lists in sequence?
Is it possible to use list comprehension on two lists, item by item, in sequence? Given A = [1,2,3], B = [4,5,6], get some C = [f(1, 4), f(2, 5), f(3, 6)]. In other words, a more direct/efficient way to do [f(U, V) || {U, V} = lists:zip(A, B)]. Similar question goes to binaries, if given A = <<1,2,3>> and B = <<4,5,6>>. This would be ve...
Binary Java 7 for Mac
Is there any binary release of Java 7 (using the Mac/BSD-port project) anywhere? Some blogs (e.g. Building Java 7 on Mac OS X) have a detailed instructions to build the jdk from source, but I was hoping that someone have a binary of it available for download. The problem with the instructions is that it's quite annoying to get all the ...

Emulating Linux binaries under Mac OS X
How do I run Linux binaries under Mac OS X? Googling around I found a couple of emulators but none for running Linux binaries on a Mac.

Traversing a binary tree in C
I'm trying to traverse a binary tree in C. My tree contains an AST node (abstract syntax tree node for compiler). ASTnode reserves nodetype which specifies given node's type (i.e INT OP or CHAR and TYPE we don't need to concern other types), the other members are left and right pointers, and finally we store. Here is code for traversing...
Reading and parsing the width/height property of a bitmap
I'm trying to write a bitmap (.bmp) parser/reader by reading raw bytes from the file and simply checking their values, and I've come across something I simply cannot wrap my mind around. The image I'm trying to read is 512x512 pixels, and when I look at the width property (at 0x12 and 4 bytes onward) it says 00 02 00 00 (when viewed in ...
