Scipy/numpy: two dense, one sparse dot product <p>Let's say we have a matrix <code>A</code> of size <code>NxN</code>, and <code>A</code> is sparse and <code>N</code> is very large. So we naturally want to store is as as scipy sparse matrix.</p>
<p>We also have a dense numpy array <code>q</code> of size <code>NxK</code... | <p>So you have</p>
<pre><code>(k,N) * (N,N) * (N,k) => (k,k)
</code></pre>
<p>One of those dot product results in a dense array; that times another dense is also dense. With a multiplication like this you quickly loose the sparsity.</p>
<p>If <code>q</code> has a lot of 0s, and you want to preserve the sparse ma... |
Fixed Time on a Clock <p>I'm attempting to make a javascript clock (done already) which displays a specific time, and the same time, to everyone who views it. Currently, it will display 16:... for me, and 21:.... for the other guy. This is due to timezones, obviously. But, I'd like for it to display one time for every ... | <p>If you want a single time for every viewer and you don't care what that time is, you should use UTC time.

<p>Technically, you should also change getSeconds to getUTCSecond... |
Static Cast from ( Base Reference to Base Object ) to ( Derived Class Reference) <p>In the <code>main</code> function below , the first <code>static_cast</code> is valid as i am trying to cast a (base class reference to <code>Derived1</code> class) to a derived reference
But why is the second cast printing with the val... | <p>A <code>static_cast</code> is a promise from you to the compiler that the base class really is a derived class -- no need for the computer to double check. You're telling the compiler that you know something it cannot know which guarantees this to be true. So when the instruction comes for the CPU to go access a v... |
