Just wondering if there would be any difference to the SEO or search engine rankings for a website if they decided to host the blog part of their website at a subdomain(blog.example.com) instead of hosting it at a path from their root domain (example.com/blog) I saw  about it that doesn't directly answer the question, it just says you should have both.
If I have example.com, and blog.example.com, do search engines see those as one site or two? Will using subdomains hurt SEO? I have some technical reasons why I can't use example.com/blog.
A question about using the "v-ing" verbs To native speakers, normally do you use adverbs to modify these v-ing worlds especially when they are the objects of the verbs?  Like:      I regret swimming hurriedly     Not      I regret hurried swimming.      Right? And what about these two sentences:     I regret stamp-collecting     or     I regret collecting stamps   Besides, when using these words, it still retains the verbal characteristics right? Like:       The house needs a careful cleaning.     has the same meaning with       The house needs carefully cleaning.     or       The house needs to be cleaned carefully.   (SOMETHING like passive voice) first of all thank you for answering.  I have a 120GB SSD and a 1TB HDD and I want to dual boot with Windows 10. I tried with this configuration:  SSD  / (ext4 20GB) /usr (ext4 15GB) /boot/efi (ext4 250MB)  HDD  /var (ext4 3GB) /tmp (ext4 8GB) /home (ext4 50GB) swap (none 24GB) (RAM 16GB)  I don't know if I am doing OK, as I tried to install it but installation gets stuck at "Saving installed packages..." and it doesn't continue. I wonder if it could be cause I didn't  partitioned as I had to. I don't find any post where this happens so I ask here.  Thanks! How does the current limiting resistor for an LED affect current and voltage drops? I'm having a bit of trouble understanding currrent limiting resistors in simple LED circuits. I know that I can determine the optimal resistor like so:  \$\displaystyle R=\frac{V_{s}-V_{f}}{I_{f}}\$  But I'm having a hard time understanding how this one value modifies the voltage and the current to the correct values for the LED. For example, if my calcuations for a super bright blue LED (with \$V_{f}\$ being 3.0-3.4&nbsp;V and \$I_{f}\$ being 80&nbsp;mA, and a voltage source of 5&nbsp;V) gives me 25&nbsp;ohms (using the lower bound of the forward voltage), that's fine. So the current throughout should be 80&nbsp;mA and the voltage drop for the resistor and LED should be 2 and 3 volts, respectively.  But what if I used a 100&nbsp;ohm resistor instead? Or any other value—how would I calculate the voltage drops and current? Would I assume one of them stays the same? Initialization of an ArrayList in one line What is a complete list of the usual assumptions for linear regression? What are the usual assumptions for linear regression?

Why Not Use Public Member Functions I want to kill all running processes of a particular user from either a shell script or native code on a Linux system.  Do I have to read the /proc directory and look for these?  Any ideas? Is there a dynamic mapping of the pids under UIDs in Linux? Isn't this in the proc?  If not, then where is this list maintained? Should I read from it? Also where is the static list of all UIDs in the system so I can validate this this user exists and then proceed to kill all processes running under it? Do I need a visa to transit (or layover) in the Schengen area? Double SOCKS5 proxy using SSH I was searching for a way to connect to one of my servers who is behind a jumpbox via SSH. I was able to do so by running the following command:  $ ssh -tt ptitpou@jumpbox ssh -tt ptitpou@targetserver   Now, I want to be able to use that server to access webservers on targetserver's network. For that, I followed  and I was able to successfully access the websites. The command I used was:   $ ssh -L 127.0.0.1:9999:localhost:9696 -tt ptitpou@jumpbox ssh -D 9696 -tt ptitpou@targetserver   The question I want to ask is how to use the ssh -o ProxyCommand to command in a slightly cleaner way. I tried to put the second part of the command as the proxy command and I had a successful SSH connection, but I was unable to use the proxy after that.   I've also tried  but the command line hangs after connecting to targetserver.  How can I do that? Am I wrong to try to use ProxyCommand option for this task? "Welcome to emergency mode!"

How to install Unity 8? I'm using Ubuntu 14.04 and found out that we can install Unity 8 on it. Will Unity 8 replace Unity 7 once I install it? And if it does can I switch back to Unity 7 if I want?

Currently I am doing rename /my/data/Andrew.doc to /my/data/Andrew.txt I would like to do this for all the .doc files from the /my/data/ folder and to preserve the name.  I tried several versions but I guess I have something wrong in the syntax as I an new to linux. I've just started using TikZ and need to create a simple triangle commutative diagram like this one.    The closest I've been able to get is this.   How do I get the h arrow to go from A2 to A3? Everything I've tried just causes errors.  Here's my current code:  \begin{tikzcd}[column sep=small] A \arrow{r}{i}  \arrow{rd}{g}    &amp; A3 \arrow{d}{h} \\     &amp; A2 \end{tikzcd} Calculation of $\int^{\pi/2}_{0}\cos^{n}(x)\cos (nx)\,dx$, where $n\in \mathbb{N}$ Compute the definite integral      $$ \int^{\pi/2}_{0}\cos^{n}(x)\cos (nx)\,dx $$      where $n\in \mathbb{N}$.   My Attempt:  Using $\cos (x) = \frac{e^{ix}+e^{-ix}}{2}$, we get  $$ \begin{align} \int^{\pi/2}_{0}\cos^{n}(x)\cos (nx)\,dx&amp;=\int_{0}^{\pi/2} \left(\frac{e^{ix}+e^{-ix}}{2}\right)^n\left(\frac{e^{inx}+e^{-inx}}{2}\right)\,dx\\ &amp;= \frac{1}{2^n}\mathrm{Re}\left\{\int_{0}^{\pi/2} \left(e^{ix}+e^{-ix}\right)^n\cdot e^{inx}\,dx\right\}\\ &amp;=\frac{1}{2^n}\mathrm{Re}\left\{\int_{0}^{\pi/2}\left(e^{2ix}+1\right)^n\,dx\right\} \end{align} $$  Letting $z=e^{4ix}$ gives us  $$ \begin{align} e^{4ix}dx &amp;= \frac{1}{4i}dz\\ dx &amp;= \frac{dz}{4iz} \end{align} $$  So the integral becomes  $$\frac{1}{4\cdot 2^n}\mathrm{Re}\left\{\int_{C}\left(\sqrt{z}+1\right)\cdot \frac{dz}{iz}\right\}$$  How can I complete the solution from here?
