I'm trying to re-create something similar to the effect . When you scroll down to the bottom of the page, an &quot;Also Check Out&quot; div slides from the right. I am assuming this works by using the jQuery function scroll and then checks if a certain div is in view or not. I, however, cannot even get the scroll function to work. I tried both using $(&quot;#div_name&quot;).scroll(function(){}); and $(&quot;#div_name&quot;).on(&quot;scroll&quot;, function(){});, but neither seem to be working. It appears that neither one of my ways of going about it are hooking the scroll functions properly. Here is my  Anyone have any ideas what I'm doing wrong in my fiddle?
I'm loading elements via AJAX. Some of them are only visible if you scroll down the page. Is there any way I can know if an element is now in the visible part of the page?
Plotting a function with an argument in degrees I want to plot a function. The function is, F is proportional to x/cos(x). Here x is rotation in degree and F is the force. I have to plot the graph where the x axis will be from 0 to 70 degree and the y axis will be linear value 0 to 5. I am not able to find any option to draw graphs where x axis is with rotational degree.

Difference between Ethernet splitter and switch I have one Ethernet port that is wired directly to the router on another level.  However, I want to run a desktop and a server both off this one Ethernet port.  Can anyone tell me the difference between an Ethernet splitter and a switch?

Given a logarithm is true, if and only if, $y = \log_b{x}$ and $b^y = x$ (and $x$ and $b$ are positive, and $b$ is not equal to $1$), are true, why aren't logarithms defined for negative numbers?  Why can't $b$ be negative? Take $(-2)^3 = -8$ for example. Turning that into a logarithm, we get $3 = \log_{(-2)}{(-8)}$ which is an invalid equation as $b$ and $x$ are not positive! Why is this?

Here's an image from another question:    I get what the pull down resistor is there to do, but I don't really understand exactly how it works.  When there is no voltage applied through the base wire, why does any induced current then go through R2, but when a voltage is applied, it goes to the transistor? My understanding is that voltage always follows the path of least resistance, so if applying say, 5v turns the transistor on, that means that the transistor has a lower resistance than R2, so I would also assume any induced current would also flow through the resistor - so why does it then go through R2? What is the difference between HAVING and WHERE in an SQL SELECT statement?

I want to prove the following theorem (no idea whether it has a name):  Let $V = \mathbb{R}^n$ or $\mathbb{C}^n$ and $\|\cdot\|$ be a norm on $V$. Then, there exist $C_1, C_2 &gt; 0$ such that for all $x \in V$:  $$C_1 \|x\|_\infty \leq \|x\| \leq C_2 \|x\|_\infty$$  I first let $x \neq 0$ (otherwise it would be trivial). Then, I divided by $\|x\|_\infty$ and normalized the vector $x$ such that $\|x\|_\infty = 1$. That left me with  $$C_1 \leq \|x\| \leq C_2$$  but I don't see how this could help me or how I could possibly limit an unknown norm. How can I proceed? Or is this the wrong way anyway?
