thanks everyone for replying so quick. That's the reason i love maemo community. i will check which one is easier for me and will start learning it.

Python. ;)

Try C++ & Qt (QML)

Also if you have JavaScript knowledge you can do simple apps with QML which will work in Maemo, Meego, Jailfish and Ubuntu Phone.

For instance.
set adress 0200 and forward in the memory to "hello world$" then write.

Mov ah,09
mov dx, 0200
call function int 21h

will print "Hello world" on the screen.

-This little routine is easy to understand, and everything from pointers to functioncalls and their parameters are explained here.
..and,everything with numbers like boolean long short signed and unsigned integers and float ... why they exist and why you cant mix them, is also very obvious when you have a grasp of how ML/assembler works.
Your example only works on x86 assembler, and INT21h calls the MS-DOS API (roughly equivalent to stdio.h, but only if there's a DOS running somewhere): DOS INT 21h - DOS Function Codes. That wouldn't work on an N900. :confused:

Lets get together and finally develop a document editor for harmattan. Hope we can finish it at least before jolla is officially released for n9.

My advice would be to stick to something as close as possible. You have a N900 or a N9? Great. There are plenty of cool things you could do with that.

You could simply start scripting on the terminal, Python is great, but I guess developing for those devices certainly calls for C++ in combination with Qt, or leave the Qt out of the equation and simply start with C++ on the command line.

Forget about Assembly, for now. It is lovely, it is beautiful but it is not true that that would be "a simple best start" to learn programming. It's not. Actually, the real best start would be a piece of paper, a pencil, a brain and some mighty interesting ideas.

Correct....

But as i said, the assemblerknowledge wasnt for to learn to make progams on the N900, it was only to get a grasp on pointers, integers float and such stuff that is used in C.
And as such it doesnt matter what assembler it is and how well you know it, it is only necessary with some basic knowledge of any assemblylanguage to get a great start in understanding C programming and avoid the problems C gives for anyone who dont have that knowledge.

But as a beginnerlanguage i still vote for Python (it is very powerful on the N900) and then when mastering the thinking behind programming in general , go over to languages with a lot more complex syntax like C.

People.

:rolleyes:

Next: someone chokes up that HTML5/webcrapps actually are da shiznit. I really expect this to happen here.
Code:
document.write('hello world')
:P

just kidding

But really please, please don't start learning programming with bash, no don't do that.

qwazix,

Only pointed (pun intended, yes...) to bash because I think it's the place where most people start to understand the fundamental ideas behind programming.

Single line execution is also nice, I guess, when you're just starting out.

But above all: The command line and scripting for it, seems less intimidating to me when you first try and understand how programming works. For that reason, I also concluded my post by stating that pen and paper should not be overlooked :)

Having said that, you are of course right, bash is not the best place to start programming. But it is a nice place to get your feet wet and see if you can live with the temperature of the water.
