Not sure where I saw this picture, but this summarize what I think JAVA is.

On a more serious note, while C being the "elite" language (also the linux kernel language), there seems to me that JAVA has more job oportunity than C.

It depends on where you want to use programming.
The tool is used in a lot of fields, so look at what people are using and learn that.
A good alternative is to ask someone from your local college what they are taught as colleges usually talk to the industry they are preparing for.

In my area, we use C++ for robotics, C# for user applications, javascript for web stuff and java for legacy stuff.
But don't let language slow you down. Just get started and learn programming. Changing language does not mean you start over from scratch.
I was tutoring a couple of students in programming (c++) and I found that they didn't have much problem with the actual c++ parts of the programming, they had problems with all the things nobody taught them. Where do you find documentation, how do you include libraries, how to write cmake, how to create modules, how to write graphical interfaces etc.
I basically threw 3 large libraries at them in a Linux environment and then had them interface it with what they previously knew.
I was never taught these things myself, but learned things out of need and interest.
If I am going to do this again, I will write it down in a more concise way, I think a language overview would be nice to have for each language.

Here's a bigger one.

yup same here, would be fun to play around with the image board concept

>>5109
try darkchan?

personally im looking for textboards if you guys want to trade?

It's a pretty simple concept, you should be able to figure it out.

You're kidding, right?

Im not sure what you would do with a language for OSX IOS systems on windows

>>5042
write in terminal

Sorry for being such a disgrace. But isn't there any simple tutorial for installing that OS COBOL?

ask your instructor to teach you a real language.

From your comments you want to send data to a MySQL. From the exception, you seem to be using Hibernate. And, more important, the error says: "nested transactions not supported". Look up your code for said transactions. Maybe you are trying to send two queries at the same time and they are not committed to the database?

And the next time, read CAREFULLY the error message and contextualize it within your code. They are there for a reason.

The main use for comments, imo, is not to make it obvious what the code is doing, but why it's doing it.

It helps readers follow along and see the logical steps being taken in code, and if you don't work on code for a while you might even forget your own code and how it worked back then..

That's the only reason I write comments, so 3 years later when it breaks on a Monday morning and I'm staring at it bleary-eyed without any coffee I can figure out what the hell is going on.

I once was porting a file format parser that used unsigned integers for pointers to Java. For those who don't know, Java only have signed ints (in Java 7, which was the version I used at that time). I spent a whole morning writing code that converted the number to a long and preserved everything as intended. Before committing I wrote a large rant about Java in the comments above the code. If I'm not mistaken, that code and comments are still there for ~3 years and counting.

Incase anyone is interested, I decided to implement the code analagous to the following pseudo-code:

for ( auto module : modules.equal_range( input ) ) {
try { auto module_class = module.second.constructor( input );
return std::unique_ptr< Module >( module_class );
} catch ( exception e ) { }
}

I let the modules advertise what inputs they support and use that do decide which loaded modules to attempt to create. In documentation I require that the module throw an exception if the input is not supported, or fails to load. I'll deal with the other issues related to that as I think of them.

I think it's kind of hard becoming a hacker. But mostly, the skills you need to train is knowing how computer network works in details.

Install a linux distribution. I really like Archlinux (hard to install, but you're going to learn a lot of stuff). Debian is also great.

Try to understand how computers interact with each other. What is actually happening when you browse the internet ? How does it work ? What is your browser actually doing when loading a website ?

Learn how to program. I recommend bash, C, python.

Understand what is a Network. Learn tools like NMAP and netcat.

Good luck.
