I don't know nothing about programming and not much about linux os.
I have now Fedora 12 and Gnome.
I have 3 websites to maintain: ( Finnish Pikavippi sites )
pikavippi
vippi
pikalainat

I'd like to have a good editor, can you recomend any ?
Suitable to Gnome?
Need to code PHP and HTML

Regards: Me... sorry I'm dumb

Haha, you've just started the Computing World's Most Contentious Argument; Emacs v Vi.

I'll go first:
Try emacs, very powerful, the syntax highlighting works brilliantly for php and html, easy(ish) to learn, very smooth, quite intuitive and well, from the console of RMS.

Many editors, but what's 'good' to one person is very subjective. I used Anjuta, but have moved to kdevelop, which I like better. Eric and Bluefish are two others I've used, but try them all, and see which you like better.

"Komodo" seems like a good editor to me. For PHP, it has command completion and function definition pop-ups. For HTML, it has some similar functions, but I must admit that I do very little in HTML direct. "Nedit" is very programmable with syntax highlighting and stuff like that. So, it can be expanded pretty easily. There are some good "HTML editors" which I think can handle PHP also (ex. bluefish). I've used it sometimes, but prefer other (more basic) editors.

I might as well cast my vote in the Vi/Emacs war... Vi! Once you have a grasp on it's commands it's a very powerful editor. (just kidding about the war part... both are pretty good editors)

But, in this case, I'm thinking an editor more like Komodo or bluefish.

Outside of the Emacs/Vi debate, I used to quite like geany

"gedit" is a good GUI editor. As is KWrite and Kate, but they are too glitchy and unstable for me. All three have syntax highlighting, but Kate and Kwrite have highlighting for more rare languages available.

As for my position on Emacs vs. vi, I can't say I think both are great but I prefer vi. Why use an editor that emulates everything your underlying OS can do and requires you to contort your fingers in funny ways just to move the cursor (Emacs)? I might use vi more, but I am learning the Dvorak keyboard and vi's motion keys would all be screwed up.

vi, clearly. Those Emacs users are all crazy

I challenge you to a duel

Bring it, bitch

What do crazy people duel with?

Reminds me of this:

Ah Arch Linux, The Emacs of the Lightweight distro world... Totally awesome

I have Gnome - how do I change it to KDE ?
I have this Gedit, but I' ve seen KDE I like it more.
I have Fedora 12

Now there is a job and a half... If you've not done much to the installation, you may find it a helluva lot easier just to find a KDE based distro and install that

If this is just because you want to use an editor from KDE, that does not mean you need to use KDE to use the program.
