Want to learn about xCode

I bought my first Mac in february and I love everything about it. that said, I've been trying to get my hands on as much software as possible and I'm interested in learning about xCode. is there somewhere I can get started, right from scratch? I don't know much about developing software at all but I'm willing to learn.
Thanks

I posted this a while back. I don't know if it was helpful or not. It is a tutorial on C programming written by the author of a very good book on Motif programming.
How C Programming Works
Since you are just starting, my advice is to stay out of Xcode, just for little bit. Go through some basic "HelloWorld" tutorials. Learn how the terminal works. Learn a little bit about the process of compiling a source file into an executable. Xcode is very good, but it hides a lot of what is going on underneath. I think you would be much more effective with Xcode if you knew a little about that hidden stuff.

  • I want to learn about workflow any one can provide the guidence for me

    i want to learn about workflow any one can provide the guidance for me

    SAP Business Workflow can be used to define business processes that are not yet mapped in the R/3 System. These may be simple release or approval procedures, or more complex business processes such as creating a material master and the associated coordination of the departments involved. SAP Business Workflow is particularly suitable for situations in which work processes have to be run through repeatedly, or situations in which the business process requires the involvement of a large number of agents in a specific sequence.
    Features
    SAP Business Workflow provides a number of tools for defining and analyzing workflows as well as for monitoring operation.
    The Workflow Builder is for displaying and making changes to workflows. You can make small extensions directly to the original workflows supplied by SAP, such as carrying out your own agent assignments or changing deadline monitoring.
    There are several Workflow Wizards to support you in the definition of workflows, with which you can create specific parts of a workflow. The Workflow Wizard Explorer gives you an overview of the existing Workflow Wizards.
    In order to make the functions of the R/3 Systems available to a workflow, you use business objects, which you can define and analyze in the Business Object Builder. These business objects are made available to the workflow in reusable tasks. The Business Wizard Explorer gives you an overview of all existing tasks.
    You can also use SAP Business Workflow to respond to errors and exceptions in other, existing business processes. You can start a workflow when predefined events occur, for example an event can be triggered if particular errors are found during an automatic check.

  • Want to learn about Apex..!!

    Hello Everybody,
    I want to know much about apex. Can somebody please guide me.
    Here's why i want to learn apex.
    I want to design one application which opens in web browser, i want to implement it on my local PC, i am using Vmware (Red Hat Linux enterprise 4 OS) as my server, Database is Oracle 10gR2 on server, i have one database created on it.
    For practice i have one package that has HTML code in it and i want to run that package on web browser, I ran that package before in my company using Apache with mod_plsql cartridge by setting up Dad configuration..
    I want to try it on my local PC. My question is do we have to install Apache with mod_plsql or just installing APEX will work in this case...???
    Any help will be greatly appreciated..
    Thanks
    Regards
    -Harsh.

    Hi,
    if you don't want to go for 11g - try 10g Rel.2 -
    my recommendation:
    1. Install the Oracle DB
    2. Download the "Companion CD", which has APEX and an OHS Oracle Http Server = Apache WITH the MOD-PLSQL integrated in it.
    http://www.oracle.com/technology/software/products/database/oracle10g/htdocs/10201winsoft.html
    looks as follows:
    Oracle Database 10g Companion CD Release 2 (10.2.0.1.0)
    - 10201_companion_win32.zip (653,693,751 bytes) (cksum - 3264572193)
    - Download latest Oracle Application Express (formerly HTML DB)
    When you start the Installer of the Compnaion CD you get the option of installing TOGETHER : APEX and OHS/Apache
    Do that ! - and its an hassle free install both installed ready to go (watch the url which is given in the status window at the end of the install and make a note).
    The APEX/Apache install takes areound 18 min. - be patient !
    TIPP: make a note of the user/pwd you used, because you need this exactly when upgrading.
    Later you can easily upgrade to the latest APEX version (Downlaod as above mentioned).
    Hope that assisted !

    BTW, to know about Hyperion please refer : http://www.oracle.com/hyperion/index.html
    Oracle and Hyperion
    Oracle has acquired Hyperion, a leading provider of performance management software. The transaction extends Oracle's business intelligence capabilities to offer the most comprehensive system for enterprise performance management.
    A year ago, Oracle significantly reoriented our business intelligence product suite, shifting our focus from offering a solution that works for Oracle-only environments towards offering a best-of-breed business intelligence product family that will work with heterogeneous information sources in an enterprise, both Oracle and non-Oracle. We introduced a new product family called Oracle Business Intelligence Enterprise Edition. This integrated suite includes Business Intelligence Tools, Oracle Business Intelligence Applications, and Oracle Data Integrator.
    The acquisition of Hyperion extends our business intelligence product strategy. Customers are increasingly using performance management and business intelligence together. Hyperion provides best-in-class performance management software to over 12,000 customers worldwide, including 91 of the Fortune 100. Hyperion will add complementary products to Oracle's business intelligence offerings including a leading open enterprise planning system, financial consolidation products, and a powerful multi-source OLAP server. Coupled with Oracle's BI tools and pre-packaged analytic applications, the combination redefines business intelligence and performance management by providing the first integrated, end-to-end Enterprise Performance Management System that spans planning, consolidation, operational analytic applications, BI tools, reporting, and data integration, all on a unified BI platform.

  • If I wanted to learn about Web Services where should I start?

    I want to start taking classes, but I'm not sure where to start. I know how to write java programs, but probably more on the level of a school project and simple programs. Is that enough for Web Services or should I take a class before a Web Services class?

    Check out JAX-WS at http://jax-ws.dev.java.net. Specifically, check out the Articles under the Documentation section of the page. Bobby has written a very good white paper to get you started.

  • Help.I want to learn about how to assign a custom request  with manager .

    Hi.
    When i submit a custom single request.I got this problem.
    No concurrent manager is defined to process this request, so it cannot be processed.
    Contact your system administrator to define a concurrent manager to process this request or to verify that existing concurrent managers have the correct specialization rules.
    Then, I check the request with request id in application manager.I found there is no manager with my program.So I think i need to assign it.But i don't know how to do it.
    So.please help me.waiting for reply...
    Thanks
