'Static readonly' vs. 'const'
I've read around about const and static readonly fields. We have some classes which contain only constant values. They are used for various things around in our system. So I am wondering if my observation is correct:
...
Check string for palindrome
... ++i1;
--i2;
}
return true;
}
Example:
Input is "andna".
i1 will be 0 and i2 will be 4.
First loop iteration we will compare word[0] and word[4]. They're equal, so we increment i1 (it's now 1) and decrement i2 (it's now 3).
So we then compare the n's. They're equal, so w...
How to apply unmerged upstream pull requests from other forks into my fork?
...applying also the eventual commits that have been added between the origin and the pull request, you can just rebase the branch on which the pull request was formed

Create code first, many to many, with additional fields in association table
...table. In a many-to-many relationship EF manages the join table internally and hidden. It's a table without an Entity class in your model. To work with such a join table with additional properties you will have to create actually two one-to-many relationships. It could look like this:

What is the cleanest way to disable CSS transition effects temporarily?
...t all was IE 10, which supported them unprefixed.)
But that's just style, and is the easy bit. When you come to try and use this class, you'll run into a trap. The trap is that code like this won't work the way you might naively expect:
// Don't do things this way! It doesn't work!
someElement.cla...
No connection could be made because the target machine actively refused it?
...topping you.
If it happens occasionally - you used the word "sometimes" - and retrying succeeds, it is likely because the server has a full 'backlog'.
When you are waiting to be accepted on a listening socket, you are placed in a backlog. This backlog is finite and quite short - values of 1, 2 or...

I have control over both endpoints and would like the receiving end to get a little bit more information. For example, I would like to pass the exception mes...
Why is '+' not understood by Python sets?
...'t have an implementation for the + operator.
You can use | for set union and & for set intersection.
Sets do implement - as set difference. You can also use ^ for symmetric set difference (i.e., it will return a new set with only the objects that appear in one set but do not appear in both se...
UILabel - auto-size label to fit text?
...etch the height, but you can change it around easily to work the other way and stretch the width with something like this, which is I believe what you want to do:
@implementation UILabel (dynamicSizeMeWidth)

float width = [self expectedWidth];
CGRect newFrame = [se...
