RandomForestClassifier vs ExtraTreesClassifier in scikit learn
Can anyone explain the difference between the RandomForestClassifier and ExtraTreesClassifier in scikit learn. I've spent a good bit of time reading the paper:
...
Where is array's length property defined?
...ytecode instruction: arraylength. So this method:
public static void main(String[] args) {
int x = args.length;
}
is compiled into bytecode like this:
public static void main(java.lang.String[]);
Code:
0: aload_0
1: arraylength
2: istore_1
3: return
So it's not access...
Set breakpoint in C or C++ code programmatically for gdb on Linux

By looking here, I found the following way:
void main(int argc, char** argv)
{
asm("int $3");
int a = 3;
a++; // In gdb> print a; expect result to be 3
}
This seems a touch hackish to me. And I think this only works on x86 architecture.

Accessing the index in 'for' loops?
... @user12379095 you probably have the data in the wrong type (a string) and you need to convert it to an actual list of numbers instead of a string. That is somewhat off topic here, please delete your comment and flag mine to be deleted as no longer needed when you see this.

...t more difficult. (I'm looking at you, database "providers" and connection strings.) So INI files are also generally better for non-manual editing, as well.

nodejs how to read keystrokes from stdin
...nswer since this capability was stripped from tty, here's how to get a raw character stream from stdin:
var stdin = process.stdin;
// without this, we would only get streams once enter is pressed
stdin.setRawMode( true );
// resume stdin in the parent process (node app won't quit all by itself
//...
In what cases do I use malloc and/or new?
... Always use new.
If you need a big chunk of data just do something like:
char *pBuffer = new char[1024];
Be careful though this is not correct:
//This is incorrect - may delete only one element, may corrupt the heap, or worse...
delete pBuffer;
Instead you should do this when deleting an arra...
