How do I use vimdiff to resolve a git merge conflict?
...
All four buffers provide a different view of the same file. The top left buffer (LOCAL) is how the file looked in your target branch (what you are merging into). The top right buffer (REMOTE) is how the file looked in your source branch (where yo...
How does having a dynamic variable affect performance?
...t represents the operation. So, for example, if you have:
class C
{
void M()
{
dynamic d1 = whatever;
dynamic d2 = d1.Foo();
then the compiler will generate code that is morally like this. (The actual code is quite a bit more complex; this is simplified for presentation pu...
Breadth First Vs Depth First
...alking a tree.
It is probably easiest just to exhibit the difference. Consider the tree:
A
/ \
B C
/ / \
D E F
A depth first traversal would visit the nodes in this order
A, B, D, C, E, F
Notice that you go all the way down one leg before moving on.
A breadth first traversa...
Can you explain the HttpURLConnection connection process?
...
The first 3 answers to your questions are listed as inline comments, beside each method, in the example HTTP POST above.
From getOutputStream:
Returns an output stream that writes to this connection.
Basically, I think you have a good understanding of how this works, so let me just reiter...
Why is transposing a matrix of 512x512 much slower than transposing a matrix of 513x513?
...rmula:
set = ( address / lineSize ) % numberOfsets
This sort of formula ideally gives a uniform distribution across the sets, because each memory address is as likely to be read (I said ideally).
It's clear that overlaps can occur. In case of a cache miss, the memory is read in the cache and the...
Library? Static? Dynamic? Or Framework? Project inside another project
...s://github.com/jverkoey/iOS-Framework
This is a pretty straight-forward guide and doesn't have the disadvantage of dealing with "fake static libraries"... check it out for more info...
Once you've created your static library, it's as easy as including it as a submodule within Git for use across di...
What is Ember RunLoop and how does it work?
... silly to asks and dependant on many things but I am looking for a general idea, or maybe if there is a minimum or maximum time a runloop may take)
At no point will the RunLoop ever keep track of how much time it's taking to propagate all the changes through the system and then halt the RunLoop aft...
Using Kafka as a (CQRS) Eventstore. Good idea?
...
I was looking at Kafka and had another concern: I didn't notice anything about optimistic-concurrency. Ideally I could say: "Add this event as item N+1 only if the object's most recent event is still N."

Where do you store your salt strings?
...
I will provide a slightly different take on this.
I always store the salt mixed in with the salted-password hash.
For example, I will place the first half of the salt before the salted-hash of the password, and the last half of the sa...
ReactJS: Modeling Bi-Directional Infinite Scrolling
...or this is to set the image dimensions in your img tag: <img src="..." width="100" height="58" />. This way the browser doesn't have to wait to download it before knowing what size it is going to be displayed. This requires some infrastructure but it's really worth it.
If you can't know the s...
