Set every cell in matrix to 0 if that row or column contains a 0
...d column are both 1s.

What is a Y-combinator? [closed]
...only functions of 1 variables and no
assignments, defining things by name, etc. (Why this is our
goal is another question, let's just take this as the
challenge that we're given.) Seems impossible, huh? As
an example, let's implement factorial.
Well step 1 is to say that we could do this easily ...
How does OAuth 2 protect against things like replay attacks using the Security Token?
...user identification, but with that said, MACs are unreliable/easilySpoofed/etc. I may just scrap the MAC address identification mechanism and go OAuth if it does allow me to uniquely identify users.

Why is my Git Submodule HEAD detached from master?
...a temporary branch can be good, and then you can just merge these branches etc. However I personally would use just git cherry-pick <hash> in this case.
$ git cherry-pick <hash> # hash which git showed you related to DETACHED HEAD
# if you get 'error: could not apply...' run mergetool a...
How to correctly implement custom iterators and const_iterators?
...
Choose type of iterator which fits your container: input, output, forward etc.
Use base iterator classes from standard library. For example, std::iterator with random_access_iterator_tag.These base classes define all type definitions required by STL and do other work.
To avoid code duplication iter...
What is normalized UTF-8 all about?
...for the NFKD and NFD. Thus NFKD(x)=NFD(NFKC(x)), and NFKC(x)=NFC(NFKD(x)), etc.
Conclusion
If in doubt, go with canonical normalization. Choose NFC or NFD based on the space/speed trade-off applicable, or based on what is required by something you are inter-operating with.

What's the difference between SoftReference and WeakReference in Java?
...e cached
reflection information about a class, or a wrapper for an object, etc.
Anything that makes no sense to keep after the object it is associated
with is GC-ed. When the weak reference gets cleared, it gets enqueued in a
reference queue that your code polls somewhere, and it discards the
associ...
Is Fortran easier to optimize than C for heavy calculations?
...*2))
Moreover statements such as FORALL, PURE & ELEMENTAL procedures etc. further help to optimize code. Even pointers in Fortran arent as flexible as C because of this simple reason.
The upcoming Fortran standard (2008) has co-arrays which allows you to easily write parallel code. G95 (open ...
Version vs build in Xcode
...ne Simulator Version/Build numbers are the same way, as are iPhones, Macs, etc.
3.2: (7W367a)
4.0: (8A400)
4.1: (8B117)
4.2: (8C134)
4.3: (8H7)
Update: By request, here are the steps to create a script that runs each time you build your app in Xcode to read the Build number, increment it, and wr...
Is there a performance difference between i++ and ++i in C++?
...i; }, never mind the actual tree structur (BSP, kd, Quadtree, Octree Grid, etc.). Such an iterator would need to maintain some state, e.g. parent node, child node, index and stuff like that. All in all, my stance is, even if only few examples exist, ...
