What will be the correct format for my URL (Here, I am trying to target the keyword 'abcxyz'): . . Please suggest if any one is correct or not for my website?
I have an URL structure like the following:     sitename.com/cellphone/nokia/galaxy-5678-nokia-cellphone-from-abc/   For more example:     sitename.com/cellphone/motorolla/new-motorolla-gta800-cellphone-from-zxy/   The directory structure is like the cellphone is the main directory of the module and the words like Motorolla and Nokia are subdirectories which are categories and then comes the title of the cellphone.  Here the word cellphone and Nokia in the first link and cellphone and Motorolla in the second link are repeated.  Is it any kind of keyword stuffing? will it be penalized by Google?
Evaluating $\int \frac{1}{{x^4+1}} dx$ I installed Dev C++ using Wine on Ubuntu 18.04 and the program is compiling but it not showing any output screen.

Ubuntu 18.10 Cosmic not starting GNOME session on bootup PreparedStatement IN clause alternatives? What are the best workarounds for using a SQL IN clause with instances of java.sql.PreparedStatement, which is not supported for multiple values due to SQL injection attack security issues: One ? placeholder represents one value, rather than a list of values.  Consider the following SQL statement:  SELECT my_column FROM my_table where search_column IN (?)   Using preparedStatement.setString( 1, "'A', 'B', 'C'" ); is essentially a non-working attempt at a workaround of the reasons for using ? in the first place.    What workarounds are available? The difficulty is that it should be cross platform. Windows 2000, XP, Vista, OSX, Linux, other unix variants. I am looking for a snippet of code that can accomplish this for all platforms, and a way to detect the platform.  Now, you should be aware of  that user.home does not work correctly, so please do not provide me of textbook answers, I can find these myself in the manuals. I've been looking for a simple regex for URLs, does anybody have one handy that works well?  I didn't find one with the zend framework validation classes and have seen several implementations. El Capitan froze and rebooted (Macbook Pro Retina Mid 2012) 2.3 Ghz Intel Core i7 8GB DDR3: Was running NetAdmin Pro which is monitoring  my office LAN, processors consumption was at  ~15 - 20%. Simultaneously I ran WiFI Explorer,  3.7% no more than 5% CPU usage. And I was  updating Xcode to v 7.3.1 and was browsing and  watching video from playground.ru Watch the videos until half of it (20mins) the Video froze I moved the mouse and turned out  the whole OSX is frozen. littleSnitch v 3.7 has no reaction I immediately pull the Ethernet adaptor and  MacBook just went to black screen. I then  switch off the wireless router. (My MacBook Pro  is connected to the network via Ethernet  adaptor and via WiFi router bearing different IP, I was thinking of cutting both network  communication, in case it was an intrusion) MacBook just restarted itself to login screen,  after 15-20 sec of black screen and total  silence) I again restarted and booted into Recovery  mode use disk utility. After completing disk  check. Login and previously opened programs resume  back (NetAdmin Pro, WiFi Explorer, Yandex  browser, Activity Monitor and AppStore) AppStore doesn't resume the download  everything else is functioning normally and in Addition I have got my calendar open after login (I did not launch accidental nor was it set to  start with system login)   Question 1: Are there any way to know what was happening and what was OS El Capitan last reaction before it froze and rebooted?  Question 2: Are there any software better than "Console" v10.11 to interpret what was going on before it crashes?  P.S. Thank you in advance, I will try to upload the Console messages later from the MacBook Pro    DDT-2:~ Chaleune$ syslog | grep -i "shutdown cause"  Jun 22 14:15:37 DDT-2 kernel[0] &lt;Notice&gt;: Previous shutdown cause: 5  Jun 22 20:34:46 localhost kernel[0] &lt;Notice&gt;: Previous shutdown cause: 5  Jun 23 15:18:23 DDT-2 kernel[0] &lt;Notice&gt;: Previous shutdown cause: 5  Jun 24 17:58:32 localhost kernel[0] &lt;Notice&gt;: Previous shutdown cause: 5  Jun 24 20:09:52 localhost kernel[0] &lt;Notice&gt;: Previous shutdown cause: 5  Jun 24 22:58:15 localhost kernel[0] &lt;Notice&gt;: Previous shutdown cause: 5Jun 25 14:43:36 DDT-2 kernel[0] &lt;Notice&gt;: Previous shutdown cause: 5  Jun 25 21:55:31 localhost kernel[0] &lt;Notice&gt;: Previous shutdown cause: 3  Jun 25 22:20:57 localhost kernel[0] &lt;Notice&gt;: Kext com.apple.driver.AppleOSXWatchdog failed to load (0xdc008012).Previous shutdown cause: 5  Jun 26 10:18:44 localhost kernel[0] &lt;Notice&gt;: Previous shutdown cause: 5  Jun 26 12:09:45 localhost kernel[0] &lt;Notice&gt;: Previous shutdown cause: 5  Jun 26 18:00:31 localhost kernel[0] &lt;Notice&gt;: Previous shutdown cause: 5  Jun 27 13:05:58 DDT-2 kernel[0] &lt;Notice&gt;: Previous shutdown cause: 5  Jun 27 22:56:11 localhost kernel[0] &lt;Notice&gt;: Previous shutdown cause: 5  Jun 28 14:18:27 DDT-2 kernel[0] &lt;Notice&gt;: Previous shutdown cause: 5  *Jun 29 18:56:21 localhost kernel[0] &lt;Notice&gt;: Previous shutdown cause: -128*  Jun 29 23:31:22 DDT-2 kernel[0] &lt;Notice&gt;: Previous shutdown cause: -128      shows the following   dsIllInstErr                  = 3,    /illegal instruction error/ dsChkErr                      = 5,    /check trap error/ userCanceledErr               = -128    gave the following interpretation:   03 Illegal Instruction The computer has a specific vocabulary of machine language instructions it can understand.

Prove that any conjugate of $a$ has the same order as $a$. I am trying to prove that any conjugate of $a$ has the same order as $a$.  Let $G$ be a group and let $a \in G$.  An element $b \in G$ is called a conjugate of $a$ if $b=xax^{-1}$.  My professor gave us a hint.  Prove $a^k=e$ iff $b^k=e$ for all $k \in \mathbb{Z}$ implies $o(a) = o(b)$.  My first move is to $b^k = (xax^{-1})^k = (x^{-1})^ka^kx^k = (x^{-1})^kex^k = (x^{-1})^kx^k=x^{-k+k}=x^0$  I am not sure that I am doing this correctly?  I am trying to get $b^k=e$.  However when I raise $(xax^{-1})^k$, I am not sure if I what I have done is correct?  I am kind of confused here. How do I access my Windows partition? I have Ubuntu 12.04 installed on my HP G62-453 TU Laptop. I cannot access the contents of my hard disk partition E. When computing the covariance matrix of a sample, is one then guaranteed to get a symmetric and positive-definite matrix?

Apostrophe difference (Ones' and Two's Complement) I apologize if this question is posted on the wrong portion of the website, but I knew no better place to ask.  I've come to see that some effects, such as super-conduction may happen at either extremely low temperatures, or at extreme temperatures (the recent discovery of superconducting iron in the bowels of the earth, for one), and this is fascinating.  My question is: can (does?) the same principle be applied to quantum effects? Would it be applicable to, for example, say that although quantum effects happen at nano scales and below they may happen on a grand scale of say, the entire Universe (as a solitary unit)?  Can said quantum effects happen at moments of say, picoseconds after the Big Bang due to the turbulence of forces involves in such an event? Or even within the core of a dying star?  Thank you for any answers or clarification of my misinformation. About the continuity of the function $f(x) = \sum\limits_k2^{-k}\mathbf 1_{q_k \leq x}$ Let $q: \mathbb{N} \to \mathbb{Q}$ be a bijection and denote the image of $k \in \mathbb{N}$ by $q_k$.  Let $f: \mathbb{R} \to (0,1)$, $$ f(x) = \underset{q_k \leq x}{\sum_{k \in \mathbb{N}}} 2^{-k} $$  Show that:  1) $f$ is strictly increasing  2) $f$ is continuous at $x$ iff $x \in \mathbb{R} \setminus \mathbb{Q}$.  My work:  Let $x, y \in \mathbb{R}$, $x &lt; y$. Then there exists $q_n \in \mathbb{Q}$ s.t. $x &lt; q_n &lt; y$. Now $$ f(x) = \underset{q_k \leq x}{\sum_{k \in \mathbb{N}}} 2^{-k} &lt; \underset{q_k \leq x}{\sum_{k \in \mathbb{N}}} 2^{-k} + 2^{-n} \leq \underset{q_k \leq y}{\sum_{k \in \mathbb{N}}} 2^{-n} = f(y) $$ so $f$ is strictly increasing.  I think my proof of 1) is ok, but how can I prove 2)? What happens to spirits/souls of other creatues than Elves and Men after their death?
