I recently started looking at programming and have been quite interested in it. The only bad thing is that I don't know how code works, where I can write it, or what languages to take into consideration.
I want to learn how to make applications for the iOS operating system, and i heard Objective C is the language for that. Is Objective C something you would recommend to a beginner?
I just wish I could grasp the concept of programming a little better and get a better understanding because, as of right now, it seems extremely complicated.
As a beginning programmer, I would advise that you'd be better served learning how computers and programs work as a general concept, which will orient your thinking as to how programs are made.
I've heard lots of good things about the Haskell language in this regard, and I would recommend you start here: http://tryhaskell.org
Once you have a good concept of how programs work, and what kind of thinking and organisation is required, then you can move on to languages like C/Objective-C, which would be very frustrating to start on.

I read about OOP and Function programming. And I found both have pros and cons.
Such as:
OOP: have side effect, and sometimes it is very usefull
Function: easy to code and think. But don't have side effect and loop.
And I wonder if I can using both OOP and Function paradigm in one project. Is it be recommended in practice?
There's nothing preventing both paradigms from being used together. Arguments on each side sometimes can be misleading as people tend to focus on languages and their features as opposed to the paradigms themselves. OOP doesn't need to have state/side effects, and functional programming doesn't always make things easier or faster. The good engineer will use the right tools for the right task, which means getting a good understanding of both.

I wanted to ask little bit generic question about Java API's. I'm new in Java, learning myself and of course I enjoy it while learning. But when it comes to Java API's, to me it's hard to understand even if I know OOP's Concepts. Actually I often confuse while reading JavaDoc's. Agree that there are bunch of information about what class's(interface, enum..) has, what they extend, implements or whatever. Even though I couldn't use them without looking from the internet.
So, what is the best way of learning those API's in general, just give me your followed way while learning Java.
The best way to learn Java is to read articles with examples. It is common approach for newbies and professionals. JavaDocs is dry, too formal and really are often confusing (especially for methods from Stream API with 3+ generic parameters).
The way I did was to read certification books, for OCA and OCP, they start from the very basic, and builds up on the top of that, with examples and exercises.
It is a really nice way to build your core knowledge of the language. With that solidified knowledge you can start reading articles about different subjects in the Java universe ...
Just be patient, code as much as possible, and it will become natural aftar some time.

I was wondering how I would go about creating a game. I do not care if it is only available on windows or it is cross-platform. Which languages would I use to create a game?
Q: Which languages would I use to create a game?
A: One could program a game in almost any known programming language. Different languages work better or worse for different types of games, so it really depends.
Remark: Without extensive knowledge of how even simple games like PacMan are coded, you will run into many issues when trying to code a more complex game. I highly recommend you try to write a simple PacMan or Tetris game using only Java, just to get a hang of things and then from there move on to more and more complex games and only then start to being with more complex game languages.

I'm learning and doing projects on Grails, but for now it's a little boring because of the repetitive work (GORM, fix bug,...) . I want to "play" a little: making something simple, but useful, so that I can get inspired again with the programing work. For example, I think of something like Workrave, or RainCalendar, or Google StreetView.
The problem is that I'm just a lone programmer, and don't have lots of time for developing my own software. So I posted this question to ask for:
Some idea about a simple-coding program, but useful, interesting (funny is a bonus).
Some where (online) for programmer like me can find interesting project to join? I can code C, C++, Java, Grails and PHP. But other languages is also welcome.
I'll appreciate any idea from everyone.
To Answer your Second question:
sourceforge
And that has a lot of projects running so take a look at their Project Help Wanted board
then join the one you like.
And that should in turn answer your first question

While studying different programming languages, I recently hit upon Icon programming language. It seems to have quite cool syntax and functions for string scanning, goal directed execution, generators etc. and it was developed quite a few decades back (1977).
There doesn't seem to be much information available on it regarding the places it is used currently. It doesn't seem to be actively developed or supported also. I was wondering if people really use this language in certain niche areas even today or is the language now primarily of historical interest? Will it have much relevance in future also?
The TIOBE programming language index http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html places it somewhere between 50th and 100th in terms of
the number of skilled engineers world-wide, courses and third party vendors.
If it hasn't gotten any further than that since 1977, I doubt it ever will.
If you're into "cool," complex languages with sophisticated capabilities, Scala may scratch your itch.
