I'm trying to make a brush that gives a sparkle effect. It's just a circle brush with a cross in the middle. Any way, when I try to define the brush preset, it says "Could not complete the command Define Brush Preset because the selected area is empty." Anyone know why this is happening?
Press CTRL + D and deselect whatever you have selected. If you attempt to define a brush preset without anything selected, it should turn the whole image into a brush, but if you are trying to make a selection then make sure that you are selected on the correct layer.

I am currently doing an PyQT5 app and I want my widgets to be stacked something like this
Is it posible and if so how can I do it?
You can use QGridLayout:
grid_layout = QtWidgets.QGridLayout()
grid_layout.addWidget(widget1, 0, 0, 2, 2)
grid_layout.addWidget(widget2, 0, 2, 1, 1)
# and so forth
The method addWidget is used for placing a widget in a certain area. First two args after widget are the positions from top and from left. The other two are the height and width.
Your canvas can be seen as a grid layout of width 4 and height 2.

I am trying to change the color of my 3D object in Blender. Is there any way to do it run time through actuators?
Thanks in advance
You can use a python script to change the colour. Most likely you want to adjust the diffuse_color property of the material, which is an array of three numbers - [0]=red [1]=green [2]=blue.
While they don't show up in the action editor you can add keyframes to the colour components to create material actions and they will show up in action actuators list to play. To animate a colour you add a keyframe by right-clicking on the colour swatch and selecting Insert keyframe or press I while the mouse is over the colour swatch. Then move to another frame adjust the colour and set another keyframe.

I have level based game and under a view controller I have a button that says start level 1. I'm using it in aso so it'd be a mess to have a button for each level cause then there would be multiple layers. I'm sure you can just use one button and change the text of it once reached to a certain point by running some code but I don't know how I would program that in xcode 5.
setTitle:forState: is the method you are looking for.
[button setTitle:#"Level 1" forState:UIControlStateNormal];

I've been putting up with this for probably too long. For some odd reason, when I used the Photoshop CS5 eyedropper tool, it sets the background colour - which is really annoying. I've never experienced this in all my years of using Photoshop. Each time I set a colour, I'm forced to then use the x keyboard shortcut to swap the background/foreground colours.
How do you get the eyedropper tool back to the default setting? (without re-installing :)
Wow - ok it was easy. Go to Window > Color, then ensure the foreground colour is the selected one. There's a really fine, almost un-noticable line around the one that is selected. Mine was set on the background colour.
You can also click on the one you want to set, in the toolbar, then pick the colour. That's what I usually do anyways I think!

I haven't got the right dimensions for my picture when i try to adjust the width and height, nder the image menu->image size, i try to give dimensions to my picture of 640 as width and 960 as height, however, i couldn't do that, here is what i got :
I try to export my picture as PNG, but the dimensions are automatically given when just adjust either the height or the width, so i didn't got the right one that i need.
You need to unclick the 'Conserver les proportions' checkbox, that will let you specify height and width without Photoshop doing any automatic scaling
