Whenever I try to print the return value of a method in my XCode gdb console (and in the value formatters), I keep getting (IMP) pointers instead of the return value. For example: print [alternateDepartures count] $9 = (IMP) 0x33725441 <-[NSCFArray count]+1> here, alternateDepartures is an NSArray of ints, as evidenced by: (gdb) po al...

The one I currently use, which is how I learned Bash and am currently learning Python, is: instant hacking tutorial (very short tutorial introducing the basic syntax, variable declaration, loops, data types, etc. and ...
On my midterm I had the problem: t(n) = 8T(n/2) +n^3 and I am supposed to find its big theta notation using either the masters or alternative method. So what i did was a = 8, b = 2 k = 3 log8 (base 2) = 3 = k therefore, T(n) is big theta n^3. I got 1/3 points so i must be wrong. What did I do wrong? ...
There are a list of tasks that are time sensitive (but "time" in this case is arbitrary to what another program tells me - it's more like "ticks" rather than time). However, I do NOT want said methods to evaluate immediately. I want one to execute after the other finished. I'm using a linked list for my queue, but I'm not really sure how...
Are there any issues when using IBAction when it is not actually called from a user's action? If you have an action like -(IBAction)sayHello:(id)sender; You can call it from within your class like: [self sayHello:@"x"] The @"x" doesn't do anything, it just fills in for the sender. You can actually create an IBAction method withou...
I'm very confused with javascript methods defined in objects and the "this" keyword. In the below example, the toString() method is invoked when Mammal object instantiated: function Mammal(name){ this.name=name; this.toString = function(){ return '[Mammal "'+this.name+'"]'; } } var someAnimal = new Mammal('Mr. Biggles'); alert...

Howdy, I'm kind of new to Python and I wonder if there is a way to create something like the magic methods in PHP (http://www.php.net/manual/en/language.oop5.overloading.php#language.oop5.overloading.methods) My aim is to ease the access of child classes in my model. I basically have a parent class that has n child classes. These class...
Hello, This guy: virtual phTreeClass* GetTreeClass() const { return (phTreeClass*)m_entity_class; } When called, crashed the program with an access violation, even after a full recompile. All member functions and virtual member functions had correct memory adresses (I hovered mouse over the methods in debug mode), but this function h...

I have an array initialized in my RootViewController and a method that addsObjects to an array. I created a RootViewController object in my SecondViewController.

Let's say I have this 170mb file (roughly 180 million bytes). What I need to do is to create a table that lists: all 4096 byte combinations found [column 'bytes'], and the number of times each byte combination appeared in it [column 'occurrences'] Assume two things: I can save data very fast, but I can update my saved data very slo...

I would like to embed Clojure code into Java. This site was helpful in the basics of setting this up, but the only arg it ever passes is of type String. I have tried using ints as well, and those also work. My question is whether there is some formatted way to pass in structured data to Clojure. In particular, I have a list of points I ...
Hi, for a long time, I am thinking and studying output of C language compiler in assembler form, as well as CPU architecture. I know this may be silly to you, but it seems to me that something is very ineffective. Please, don´t be angry if I am wrong, and there is some reason I do not see for all these principles. I will be very glad if ...
