This one should be easy, however for some reason I can't find an easy way to solve it. So if f is a $C^1$ function over $\mathbb{R}$ that is decreasing and positive (so converging to some value, let say 0 since it does not really matter). Can we know for sure that $f'$ will be converging to 0? I know this is not true if f is not decreasing or increasing.  Thank for any hint  All the best T.
Let $\,f : \mathbb{R} \rightarrow \mathbb{R}$ be a infinitely differentiable function that is  increasing and bounded. Then is it true that $\lim_{x\to \infty}f'(x)=0$?
Limit $\frac{x^2y}{x^4+y^2}$ is found using polar coordinates but it is not supposed to exist. SQL to generate a list of numbers from 1 to 100 Raise all windows with a specific title I'm trying to find a way to raise all the windows that have one, specific title.  For example, I have two windows named superconky (yes, you guessed it, I'm trying to get conky running in lubuntu).  I have a command I got from the LXDE forums: sh -c 'wmctrl -k on; wmctrl -a superconky;'  I use it to show the desktop, except conky. It works perfectly, but only if you have one conky. If you have two or more, you get left with one and all the others minimized.  So, what should I do to raise all the windows?  Thanks in advance. Graphing the amount of time a function takes Wouldn't multiple filters in a convolutional layer learn the same parameter during training? Based from what I have learned, we use multiple filters in a Conv Layer of a CNN to learn different feature detectors. But since these filters are applied similarly (i.e. slided and multiplied to regions of the input), wouldn't they just learn the same parameters during training? Hence the use of multiple filters would be redundant? I understand using phone while it is being charged by a normal charger is not advised. What about using phone while it is being charged by a portable charger (powerbank)?  I own a HTC one and i was told by a mobile technician HTC’s own portable charger only should be used for HTC one. How much truth is there to it as HTC powerbank is not available in my city and i am thinking of using Sony portable charger for charging my HTC One?

With lots of guides and setup variations all over the internet, I find it confusing which is which to really follow. Normally, in Windows 8 my setup would be install everything in the HDD and use Intel Smart Response for a speedy setup. However as I am new to Linux I really don't know what to do.  My ideal setup would be something similar to this, but I know for a fact that IRST is not available in Linux so what I intend to do is keep the OS files in the SSD instead and keep my media on the larger HDD. A step by step procedure would be extremely helpful.     Edit: I want a system running solely on Ubuntu, with the SSD to speed things up but setting it in such a way that it does not hasten its lifespan.    # /etc/fstab: static file system information.  # # Use 'blkid' to print the universally unique identifier for a  # device; this may be used with UUID= as a more robust way to name devices  # that works even if disks are added and removed.

In the  a line is delivered at around 1:41 where Han Solo says "a 190 years old!?

When connected to the Internet, the system checks if it's in a walled garden, which is simply trying to connect to Google. If it fails, in Android 5, there'll be an exclamation mark on the WiFi icon or signal icon.   In some situations, this is annoying. Say, in China, Google is blocked, the exclamation mark will always be there, which is meaningless.  How can I disable this check, and make the system assume, connected WiFi/mobile data is connected Internet?
