@SideOnly(Side.CLIENT)

means

w.isRemote

is a tautology.

From the Wikipedia article on Tautology (logic):

In logic, a tautology (from the Greek word ταυτολογία) is a formula which is true in every possible interpretation.

The statement is always true. Have a look at the argument forms of Propositional logic. It will help immensely when using boolean statements in the future, as well as in general.

 

Besides, don't you want to open the GUI specifically when the world is remote, ie. when the code is run on the client?

A bit, but these forums are exclusively English, I believe.

 

    @SideOnly(Side.CLIENT)
    public boolean onBlockActivated(World w, int i, int j, int k, EntityPlayer player, int l, float m, float n, float o)
    {
            TD_TileEntity_SpeedFurnace tileentityfurnace = (TD_TileEntity_SpeedFurnace)w.getTileEntity(i, j, k);

            if (tileentityfurnace != null)
            {
            	player.openGui(Main.instance, 1, w, i, j, k);
            }

            return true;
    }

Oh, has @SideOnly been deprecated in favour of World#isRemote?

 

I wish I had known ...
