Using HTML5 and CSS display 2 images level with each other, and each with
a list below
I'm new to CSS. I want to code a page in HTML5 that has 2 rather large
images of equal size and level with each other and with space between
them. I also want a left-margin between the left image and the left edge
of the page.
Directly below each image there will be an unnumbered list of 6 or so
items. Would someone be so kind as to draft the code for this? I know one
way to use CSS for spacing the images:
img { margin-right: 38px; margin-left: 50px; }
But what to do about the lists?
Thanks

iOS block release and self retain cycle
iOS block release and self retain cycle
Im doing some research on blocks, the code here
typedef NSString* (^MyBlock)(void);
@property(copy,nonatomic) MyBlock block1;
in viewdidload
self.block1 = ^{
self
NSLog(@"do block");
return @"a";
};
of course the self is retained, then I do a
self.block = nil;
by checking the retain count of self, I found it reduced by 1, no retain
cycle.
I believe this is the correct situation, the block retains self, when
release the block, self gets released. retaincount reduced.
I made a litte change, and things coms strange: make block a local variable.
in viewdidload
MyBlock block1 = ^{
self
NSLog(@"do block");
return @"a";
};
[block copy]; // retain count of self gets added.
[block release]; // retain count of sell still the same
why? I tried Block_release(), its the same. and when putting a local
variable like NSArray in the block, the retain count fellows the same rule
as self.
there must be some thing different inside of @property, anyone researched
this before? pls help.
Additionally, I do this in ARC, a local variable block will made the
retain cycle, and a instance variable didnt, due to the autorelease, it
holds the self, and few seconds later, it released and self object get
released normally.
is it because the instance variable and local variable are alloc on
different parts in memory? stack ? heap?, are they both copied to heap
when do a [block copy]?
EDIT : not instance variable and local variable. using @property makes it
different, any explanations?

How to solve the CharacterControl issue?
How to solve the CharacterControl issue?
We who use jme3 have a problem with the BetterCharacterControl that
setMaxSlope is not implemented. The developer of the engine says that we
can solve this for ourselves using the new controller:
http://hub.jmonkeyengine.org/forum/topic/setmaxslope-for-bettercharactercontrol/
And I would really like a solution since my game needs this.
I asked about this before but we didn't solve it:
How to improve character control for my 3D game?
Can you help us progress? I've recorded a video with the problem:

How to remove each item that appeares in first collection from second collection using linq?
How to remove each item that appeares in first collection from second
collection using linq?
Suppose I have 2 collections:
1) {1, 2, 3, 5}
2) {2, 5}
I want to remove each item that appears in second collection from first
collection, so I will get:
{1, 3}
Questions:
How can I do this with Join OP (better with extension methods syntax)?
And is there any way I can iterate over two collections as I do with
nested for/foreach loops?

pushViewController doesn't work
pushViewController doesn't work
I have a UIViewController, I want to navigate from this view to my second
view controller
SecondView *secondView=[[SecondView alloc] initWithNibName:@"SecondView"

[self.navigationController pushViewController:secondView animated:YES];
[secondView release];
It doesn't work. It doesn't do anything and there is no error. What I'm
missing?
