  • At What point should you understand References?

    - by Vaccano
    I asked a question like this in an interview for a entry level programmer: var instance1 = new myObject{Value = "hello"} var instance2 = instance1; instance1.Value = "bye"; Console.WriteLine(instance1.Value); Console.WriteLine(instance2.Value); The applicant responded with "hello", "bye" as the output. Some of my co-workers said that "pointers" are not that important anymore or that this question is not a real judge of ability. Are they right?

  • How can I retrieve all the returned variables from a function?

    - by user1447941
    import random def some_function(): example = random.randint(0, 1) if example == 1: other_example = 2 else: return False return example, other_example With this example, there is a chance that either one or two variables will be returned. Usually, for one variable I'd use var = some_function() while for two, var, var2 = some_function(). How can I tell how many variables are being returned by the function?

  • Where to put the star in C and C++ pointer notation

    - by Martin Kristiansen
    For some time the following has been annoing me, where should I put the star in my pointer notation. int *var; // 1 and int* var; // 2 obviously do the same thing, and both notations are correct, but I find that most literature and code I look at use the 1th notation. wouldn't it be more 'correct' to use the 2th notation, separating the type and the variable name by a whitespace, rather than mixing the type and variable tokens?

  • Ubuntu 9.10 Server (minimal virtual machine) partitioning

    - by John
    I am setting up a generic Ubuntu server and am trying to figure out the (best) way to partition the machine. Again, this is just a generic one: The default drive is 20GB. Some guides show: Separate /home, /usr, /var and /tmp partitions Another one suggested something like this: / 4GB /boot 512MB /tmp 1GB /home 5GB /usr 5GB /var 5GB What is the best way to accomplish this?

  • jquery, javascript and callback timing

    - by Blankman
    var blah = Some.Thing(data, function(a,b) { // code here }); Some.Thing = function(data, callback) { var a = Other.Thing(data, function() { }); }; My question is, will the part that says //code here fire ONLY after everything else and their callbacks fire? The //code here part seems to fire, and there seems to be some timing issue.

  • check all values match using prototype

    - by snaken
    Using prototype, is there a simple method of checking that a group of values match, for example - can this code be refined to a single line or something otherwise more elegant? var val = ''; var fail = false; $('form').select('.class').each(function(e){ if(!val){ val = $F(e); }else{ if(val != $F(e)) fail = true; } });

  • Should Javascript's "for in" construct iterate the length property?

    - by Eric
    I'm making a bookmarklet, but I've encountered some wierd behaviour in IE8. The code causing the problem is this: var els = document.getElementById("my_id").getElementsByTagName("*"); for(var i in els) { alert(i+","+els[i]) } The first thing that is alerted is "length, n". This isn't the case in chrome: just in IE8. Interestingly, it seems to behave differently depending on whether the code goes in the console/address bar or the page itself. Is this standard behaviour?
