How to start programming from a novice,layman?

Dear gurus,
I learned something about SQL by installing a database XE, but when it comes to PL/SQL, I lost my mind, I cannot understand even the easist code of a procedureal programming language.
I learned much about SQL but now I think it is time for me to learn something about procedureal programming language.
But i find PL/SQL may not for novice ,
Is there any one fore a starter, ?
Is Java Ok for a beginner?
(Keep in mind this man know nothing about programming at all, he learned some Visual Basic at college, but on every exam he got less than 10 scores(100 for total), and two years past, he got nothing left behind)
Thanks,

Hi Gurus,
Thanks, I cannot just wait and waste time for choose the best entrance.
I have to dig in on a specific language and after a while I will get more clear insights about the road to programming.
My original concern is Application makings with Database, cause first i got some knowledge about SQL and I made some simple-but-easy to use Applications by APEX, then I find if I want to move further and make more better applications I have to learn something about programming. But i find PL/SQL hard to start(or I am too lazy and I need try serveral more times) if you know nothing about programing.
So I choose to learn one, I may make mistake and I may choose a wrong language but anyway i think it is worthy to learn and then find my actual need.
You know, blind dating works , if you got no other choices.

FaceTime and iChat?..how to start chat from my iPad to a Mac on iChat?

how to start chat from my iPad to a Mac on iChat?

Yes, that is exactly what I mean.
The iPad can only do FaceTime and FaceTime is NOT linked (compatible) with iChat.
If your parents have an older Mac, or are only on Leopard, Tiger or such, you could use Skype.
It's free. The video quality isn't quite as good, but it does work. Your parents would need the Skype program installed on their Mac. You can download the free Skype for iPad.

HT4673 how to uninstall programs from Mountain Lion?

how to uninstall programs from Mountain Lion?

Hi,
Theres a couple ways to uninstall programs. The launchpad is the rocket icon on the dock. If you open that you should see your apps spread out as icons as if it would be on a iphone or other iOS device. If you just click the icon with your mouse button and continue holding the mouse button the will shake and show the X. If you click that X it will ask if you want to delete the program. This only works for programs downloaded through the APP Store. If a program does not have an X then proceed to the next way of uninstalling
-- The way to delete a program that will not delete the previous way is as followed:
Open finder
- On the left side you will see applications > Click that
- Then you will see all the programs on the right side.
- If you click on the program and drag it to your trash bin it will ask if you would like to make changes and delete.
- Just make sure not to delete anything that was preinstalled with you Mac

How can start service from the spfile, on Windows 2003,

On Windows 2003, how can start service from the spfile?
connect to the database as sysdba and startup will start from the spfile.
Once I use wondows Service for shutting down and startup datbase it start from the pfile.
Which defeat my ability to change parameters at the system level.

Hi,
I'm not sure, but maybe your windows Instance service was created with
C:\> oradim -new -sid <SID> -startmode m -pfile C:\oracle\product\10.1.0\admin\pfile\init.ora
then, you need edit this service with command like below:
C:\> oradim -EDIT -SID <SID> -spfile C:\oracle\product\10.1.0\admin\spfile<SID>.ora
Take a look on this link before make any changes:

How to Start Skype from the background from command line?

Hello.
My window manager is Evilwm and I am running Skype. If I close the Skype window (the one w/ my buddies listed) the window closes but Skype is still running in memory. On another window manager like Openbox a small Skype icon sits in the taskbar as long as it is running. If I want to start Skype to see who is online I simply click the icon in the taskbar.
Now, the question is...How can I start skype from the command line while it is running in the background?
Evilwm doesn't have any taskbar or tray thingie...
Any ideas?
Any advice is appreciated!
Thanks!
nedson :?:

Thats what I thought...
What I wanted to do was call Skype from memory. Under Evilwm I can close a window with ctrl-alt-x (using a hacked version of EvilWm) . After cloasing the window with this method, skype is still running in memory (I can see it when running ps aux). How can I call it out of memory? I don't want to stop the program, start it back up and re login. I just simply want to call it from the background...
Any ideas?

I do not know where to get this file from. Please help!
I am running ColdFusion standalone.
Any help is much appreciated,

Utl_file how to start reading from a certain position?

Hi all,
i'm currently using utl_file to read a text file and import to db. i have managed to do it. however i would like to avoid reading the first line as it is the header. i would also like to avoid the last line as it is the footer.
how do i use the function of get line to start reading at a certain position? i am also able to get the length but i do not know how to make it start reading from a certain position.
the length of the first line will always be 9 and length for the last line would be 51.
here's my code so far:
set serveroutput on
declare
vSFile   utl_file.file_type;
vNewLine VARCHAR2(4000);
file_name VARCHAR2(200) := 'read.txt';
v_exist     BOOLEAN;
v_length number;
blocksize   NUMBER;
temp_value varchar2 (4000);
BEGIN
vSFile := utl_file.fopen('MYDIR', file_name,'r');
IF utl_file.is_open(vSFile) THEN
    LOOP
      BEGIN
        utl_file.get_line(vSFile, vNewLine);
        IF vNewLine IS NULL THEN
          EXIT;
        END IF;
      EXCEPTION
        WHEN NO_DATA_FOUND THEN
          EXIT;
      END;
    END LOOP;
    UTL_FILE.FGETATTR('MYDIR',file_name,v_exist,v_length,blocksize);
    dbms_output.put_line(v_length);
    COMMIT;
END IF;
utl_file.fclose(vSFile);
END read_demo;

Hi,
utl_file has an fseek procedure for moving the file pointer around in a file, either absolute or relative number of bytes.
It's in the documentation, I'm surprised you didn't see it there when you looked before going to the hassle of asking us a question.

How to start programming in os x or ios

Hi Guys,
Someone please can give me some advice or link or smtgh, if i want to start programming in os x?
I really like apple's stuff
Thanks,
Peter

First of all, you should be familiar with the concept of programming and software development. If that's the case, the next step is to become a good programmer in C or C++. As you know, C++ is a superset of C, with the ability to do object-oriented programming in advanced. It is the only language that helps you to gain a deep understanding of OO design and implmentation. There are a lot of books out there, but I recommend:
1. Teach yourself C by Herbert Schildt.
2. Teach yourself C++ or C++ from the ground up both by Herbert Schildt.
3. The C++ programming language by Bjarn Stroustrup (The creator of C++).
4. Learn C on the Macintosh by Dave Mark.
5. Learn C++ on the Macintosh by Dave Mark.
5. Objects, Abstractions, Data Structures and Design using C++ by Elliot B. Koffman and Paul A.T. Wolfgang. (A must read book)
Knowing C/C++ is a great ability, as it allows you to develop software for any other platform you want, such as Microsoft Windows or Linux or anything else. In fact, the underlying structure of all operating systems used today, has been implemented in C or C++. There is Unix operating system at the core of Mac OS X. So you can also make programs for Mac OS X using C or C++.
The object-oriented API of Mac OS X is called Cocoa and Apple has chosen Objective-C at this level. This language is also a superset of C and is very powerful. It is a dynamic programming language as opposed to C++. Learning to program in Objective-C is not so hard, and it just takes some time to get comfortable with the syntax and the dynamicity of the language.
If you learn to program for Mac OS X, then you can easily port your knowledge to iOS. There is also Unix at the kernel level of iOS, so there are a lot of similarities in both operating systems.
There are a lot of books and resources to learn to program for Apple devices. You should know that after learning to program in Objective-C, which is nothing special other than doing OOP in C, you should learn about Cocoa, it's architecture, design, and huge class library used to create applications for Mac OS X. And to create apps for iOS, you need to be familiar with Cocoa Touch, the litle brother of Cocoa.
My recommendation:
Books:
1. Objective-C for absolute beginners - Apress
2. Learn Objective-C on the Mac - Apress
3. Programming in Objective-C 2.0 - Adisson Wesley (recommended by most programmers)
4. Learn Cocoa on the Mac - Apress
5. Cocoa Programming for Mac OS X 4th edition - Adisson Wesley
6. Cocoa Design Patterns - Adisson Wesley (Very important to read - it is about OO design patterns used in Cocoa)
7. Pro Objective-C Design Patterns for iOS - Apress (I have not yet read it, but I think it is good)
8. Beginning iOS 6 Development - Apress (There are a lot of books on iOS programming out there. I have not read this one yet, but I think it is good to take a look at.)
At the end, you always have to use developer documentation provided by Apple, which is accessible through developer.apple.com web site.
Hope this short brief introduction helps you.
If there are anything you want to know, feel free to let me know and I will help you as far as I can.

How to start video from specific time

hey frnds,
how can we start video from given time in osmf player and also how to ad cue point to stop it

I'd like to do something similar , i.e load a streaming resource but have it play from time "n" rather than time 0.
I looked at clipStart, but that seems to truncate the video to start from time n, in other words when I use clipStart, I dont seem to be able to seek to a point between 0 and "n"
Using play() and then seek() to "n", seems to work but causes it to buffer twice, which looks really bad to a user who just wants to start the video from time "n".
Is there another way to achieve this?
Thanks,
- abey

How to start KDE4 from slim?

Hi Everybody
I have slim as the LogIn manager.
Also kde3 and openbox as my standard DE
Now I wanted to give KDE4 a try.
But how can I start it from slim?
startkde of course starts my KDE3 from /opt/kde.
And another startkde in /usr/bin doesnt exist.

http://wiki.archlinux.org/index.php/SLIM
Did using exec startkde not work?
Ah, wait. Are you using both KDE3 and KDE4? (You should have said so more clearly)
I would suggest typing the full pathname to the startkde you want.
Ahead of time, if you're using the official repos, I would switch to KDEmod if only for compatibility between KDE3 and KDE4. There's been problems I believe with using both from the official repos. KDEmod3 and KDEmod4 work fine together. If you really don't like KDEmod, a chroot might be the only solution.
Myself though, I wouldn't even try running both - no need, unless you for some reason truly need both at once. For just testing, backing up your .kde config folder and then removing KDE3 and getting 4 should be enough - you can go back if you want after.
