  • Can java do a timer on command line by overwriting the time on the same line?

    - by javaLearner.java
    HI I am a new java programmer (very new). What I want to do/test is (not sure if its recommendable or doable?), we know that System.out.println("Message"); will output the "Message" in command prompt.

Name, like instead of displaying: 10:00:01 10:00:02 10:00:03 I wand to have liek this: 10:00:0X where X will continue counting

  • Graph generation on iPhone

    - by Parrots
    Anyone have experience with drawing graphs on the iPhone? Looks like GraphKit isn't an option, so it's up to the programmer to either write his own library (using OpenGL, I guess), or an existing library. I can't seem to find any libraries that are confirmed to work on the iPhone. If you've written your own how did you go about it (opengl, quartz, etc), or if you used a library which one?

  • Importing data and keeping ids and relationships

    - by Justin Hamade
    I am working on cleaning up a mess that another programmer started. The created 2 identical databases for different locations but that obviously caused major issues. They are using cakePHP and there are quite a few relationships. I am pretty sure I will have to write a script to import that data from on DB to the other and keep all the relationships but was wondering if there is an easier way to do it.

  • What's the difference between $get and $find in JavaScript?

    - by RoboShop
    Hi, I'm a .NET programmer who've just started to learn more about client side scripting, and I was wondering sometimes you use $get('value') and $find('value') and I've discovered that these are just shortcuts for document.getElementById('value') and Sys.Application.findComponent('value'), respectively. However, I still don't understand: what is the difference between these two functions in JavaScript? What exactly are they looking up/retrieving when invoked? Thanks in advance.

    - by tom d
    I am taking over someone elses code. What are some good ways to learn what that programmer did as quickly as possible? I have been running it, stepping through it and looking at the callstack.

  • What do you do when a client ask for a feature which is a really bad idea?

    - by TAG
    Recently there was a SO question asking how to implement a feature which blocked users from copying text from a page in their browser. There were many negative comments on this feature, both because it's not practically possible to implement effectively and because it will interfere with the users' experience? What's a programmer to do in these sorts of situations in dealing with their clients or employers?

  • At What point should you understand pointers?

    - 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?

  • Do you use Python mostly for its functional or object-oriented features?

    - by Eric
    I see what seems like a majority of Python developers on StackOverflow endorsing the use of concise functional tools like lambdas, maps, filters, etc., while others say their code is clearer and more maintainable by not using them. What is your preference? Also, if you are a die-hard functional programmer or hardcore into OO, what other specific programming practices do you use that you think are best for your style? Thanks in advance for your opinions!
