  • My mental block - struggling to learn Objective C

    - by iqessar
    Hello people, this would be my first question after signing up! Anyway heres my question, I did Java at university and I was always told I am a good programmer. However I never pursued it as a career - I went into support and management instead. Im pretty much bored with my job, I have therefore started to learn Objective C so that I can develop apps for the iphone. I am currently watching several different Videos / Books. My problem is that when I go through the Apple documentation, although I understand most of it, sometimes I stumble. I believe that because you/we have the Apple documentation (i.e. Framework references) , everything should be clear, and therefore you should have no need to refer to a book or video (in order to learn how to use a particular class). But I alway do refer to a book and video and subsequently feel guilty as I believe the framework reference should be enough. (I therefore feel I am not up to being a programmer) I also believe that you shouldn't need example code in order to learn how to use a particular class because Apple provides documentation for each class, but AGAIN I find my self googling example code and I find my answer like that - again I feel guilty for doing this. Am I right in saying that Apple documentation is simply not clear? and that its ok to refer to a video/book or google? or forums for that matter? I have proffesional programmers who tell me that I am worrying too much and that I should get on with it and use all the resources that I have. I just cant seem to get round this mental block that I have in my head. When I start a programming project I am able to use the excellent search skills that I have to find the code I need, copy and paste it (yes I do understand it) BUT then I feel guilty telling myself that why didn't you think up the code yourself???? Therefore your not a real programmer, your just good at googling. Currently I am going through 20+ books so that I can learn most of the frameworks, syntax etc to develop iphone apps. I believe if I do this, then when I think of a project I can make it quickly. Should I read a few books, like 2-3 and then just start a project /app , and if I get stuck just google it and get the code I need? Can anybody please answer my questions?

  • Why Emacs/Vim/Textmate? Isn't Xcode good enough?

    - by ivanTheTerrible
    Hi I mostly do C++, Objective-C programming. And I found Xcode plus an auto completion/macro plugin (Completion Dictionary) quite adequate. However, all people seem to praise over their pure text editors. I tried Textmate for a bit; liked its simplicity but dislike its files/framework handling. Am I missing something here? Or, do Vim or Emacs have auto-completion as good as Xcode?

  • What exactly can concrete domains be used to describe?

    - by Exander
    I have read the formal definition of a "concrete domain", but I still don't quite get it. Could someone explain it to me in simpler terms, preferably with some examples? The definition is available in Reasoning in Description Logics with a Concrete Domain in the Framework of Resolution by Ullrich Hustadt, Boris Motik, Ulrike Sattler. Page 1, Definition 1.

  • .NET read binary contents of .lnk file

    - by Flores
    I want to read the binary contents of a .lnk file. As long as the target of the shortcut (lnk file) exists this works fine with IO.File.ReadAllBytes(string file). BUT If the target of the shortcut does not exist (believe me I want this) the method only returns zero's. I guess this is because the OS follows the link and if it does not exist it returns zero's Is there some way to bypass the fact that the framework follows the target of the .lnk before displaying the contents of the .lnk file?

  • class vs structure c#

    - by Enriquev
    I'm doing course 3354 (Implementing System Types and Interfaces in the .NET Framework 2.0) and it is said that for simple classes, with members variables and functions, it is better to use a struct than a class because of overhead. I have never heard of such a thing, what is the validity of this claim?

  • Suggestions for open source testing tool for cloud computing

    - by vikraman
    Hi, I want to know if there is any open source testing tool for cloud computing. We have built a cloud framework with Xen, Eucalyptus, Hadoop, HBase as different layers. I am not looking at testing each of these tools separately, but i want to test them from the perspective of fitting into a cloud environment (for example scalability of xen hypervisor to handle multiple VMs). Would be great if you can suggest me some tool (open source) for the above.

  • What version of Apache HTTP Client is bundled in Android 1.6?

    - by Benju
    I want to have a seperate project that runs my server communication code in a normal JVM for the purposes of integration testing. This code uses these libraries which are build into the Android Framework... http://developer.android.com/reference/org/apache/http/client/package-summary.html Does anybody know what version of Apache HTTP Client this is supposed to be? I want to run it without the Android tests which are painfully slow.

  • Unit testing MVC.net Redirection

    - by Dan
    How do I Unit Test a MVC redirection? public ActionResult Create(Product product) { _productTask.Save(product); return RedirectToAction("Success"); } public ActionResult Success() { return View(); } Is Ayende's approach still the best way to go, with preview 5: public static void RenderView(this Controller self, string action) { typeof(Controller).GetMethod("RenderView").Invoke(self,new object[] { action} ); } Seems odd to have to do this, especially as the MVC team have said they are writing the framework to be testable.

  • HTML Encoding with ASP.NET

    - by Corin
    I am currently html encoding all user entered text before inserting/updating a db table record. The problem is that on any subsequent updates, the previously encoded string is reencoded. This endless loop is starting to eat up alot of column space in my tables. I am using parameterized queries for all sql statements but am wondering would it be safe to just let the .NET Framework handle this part without the HTML Encoding?

  • Validation library PHP / Javascript

    - by pistacchio
    Hi, could someone recommend a PHP form validation library (that works independently outside of any php framework) that apart from doing all sort of basic validation (is empty, vs regex, is email, is alphanumeric and so on) can produce javascript code (ideally to work with jquery) to validate the very same form with the very same rules client-side and hence define validation rules in a single place and have a form validated both server and client side? Thanks.

Google has refused me Adsense account due to this lack of navigation.
