I've seen that the question of whether we could  has been asked before. However, what about filtering by users? Let's say, there are certain users whose questions I really appreciate, or conversely, there are certain users whose questions I sometimes don't want to see. Currently, I can't filter by user the same way I can filter by tags. Would this be something possible but I just don't know how? Or if not currently possible, could it be a feature to be considered for addition? I could bookmark those users' profile page to see what they have been posting, but it's not quite the same as a filter for questions. I wouldn't have to open dozens of bookmarked profile pages, for example.
I want to do a search on StackOverflow for a few terms, but also by user, since I know which user referenced the item I'm looking for.
Complete Statistic: Uniform distribution Take a random sample $X_1, X_2,\ldots X_n$ from the distribution $f(x;\theta)=1/\theta$ for $0\le x\le  \theta$.  I need to show that $Y=\max(X_1,X_2,...,X_n)$ is complete.  Now, I know I should multiply the sample distribution of $Y$ and multiply it with a function of $Y$, then integrate over the range of $\theta$ and equate them to zero. But how do I get the sampling distribution of $Y$? How do I boot Windows 8 into Safe Mode? I have Windows 8 Enterprise x64. It's installed a virtual machine. After trying to update VMWare's guest extension it black screened. After resetting it, now the virtual machine won't boot. It just says "automatic repair couldn't repair your PC"   Everything I do ends with an error or it coming back to this screen. If I go to Troubleshoot > Advanced Options > Start up settings and then go to Safe Mode, all it will do is say "preparing automatic repair" and then "diagnosing your PC" and then will come straight back to the "automatic repair couldn't repair your PC" screen. It's as if it doesn't even attempt to go into safe made.   Is there anything else I can do before I reformat? Show that every prime $p&gt;3$ is either of the form $6n+1$ or of the form $6n+5$, where $n=0,1,2, \dots$ I want to show that the two annuli $$A=\{r&lt;|z-z_0|&lt;R\} $$ $$A'=\{r'&lt;|z-z_0'|&lt;R'\} $$ are conformally equivalent (i.e. there exists a biholomorphic map between the two) iff $$\frac{R}{r}=\frac{R'}{r'}. $$  Sufficiency:  Suppose the ratios of the radii are the same. A suitable scaling (by $\frac{r'}{r}$) will make $A$ congruent to $A'$, and a translation will map the scaled $A$ onto $A'$. This is clearly a conformal homeomorphism.  Necessity:  The annulus $A$ has the following set of periods $$\left\{ \pm \frac{2 \pi}{\log (R/r)} \right\} $$ (this step required some computations which I will omit)  Similarly $A'$ has   $$\left\{ \pm \frac{2 \pi}{ \log(R'/r')} \right\}$$ as its set of periods. Since the set of periods is a conformal invariant. The ratios of the radii must indeed by the same.  Is this proof correct?   Thanks! How to use "grep" command to find text including subdirectories I want to find all files which contain a specific string of text.

How do I need to configure SMTP Auth? I have dedicated FreeBSD box, The email sending without  is working perfectly but very slow. The receiver receives email after almost 15 mins. I checked the maillog it says delays and timeouts that means the server keeps on trying to send email again and again until it successfully sends one. This is consuming lots of CPU.

The tournament is held every 5 years, which would put the next one in , the year . Did they carry on with the tradition, or was it deemed too risky again? "It's time something was / were done about the problem." It's time something was done about the problem.   It is a sentence from Murphy's "Grammar". Using was confused me, for me it should be were. It looks like this clause is in subjunctive mood&mdash;something that is unreal / imaginary, and in that case you always use were for any object.  Unless, of course, it is not the subjunctive mood, what would knock me down. Assumed True until proven False. The Curious Case of the Vacuous Truth Given two statements, $P$ and $Q$, and the logical connective, $\implies$, the truth table for $P \implies Q$ is:  $$\begin{array}{ c | c || c | }   P &amp; Q &amp; P\Rightarrow Q \\ \hline   \text T &amp; \text T &amp; \text T \\   \text T &amp; \text F &amp; \text F \\   \text F &amp; \text T &amp; \text T \\   \text F &amp; \text F &amp; \text T  \end{array}$$  Lines one and two are quite clear. What is ambiguous is lines three and four.  One explanation as to why $P \implies Q$ is true when $P$ is false, provided by Velleman goes:     Let $P(x)$ be the statement $x&gt;2$ and $Q(x)$, $x^2 &gt; 4$. When $x=3$, $P$ is true, and $Q(x) = 9$ thus $Q$ is true. If $P(x) = 1$ then $Q(x) = 1$ and they are both false. If $P(x) = -3$ then $Q(x) = 9$ and so the statement is true.   This explanation was quite unsatisfactory to me. Looking at Enderton, we have:     For example, we might translate the English sentence, ”If you're telling the truth then I'm a monkey's uncle,” by the formula ($V \implies M$). We assign this formula the value $T$ whenever you are fibbing. In assigning the value $T$, we are certainly not assigning any causal connection between your veracity and any simian features of my nephews or nieces. The sentence in question is a conditional statement. It makes an assertion about my relatives provided a certain condition — that you are telling the truth — is met. Whenever that condition fails, the statement is vacuously true.      Very roughly, we can think of a conditional formula ($p\implies q$) as expressing a promise that if a certain condition is met (viz., that $p$ is true), then q is true. If the condition $p$ turns out not to be met, then the promise stands unbroken, regardless of $q$.   Though a significant improvement over the Velleman explanation, I still feel uncomfortable with it.  Really, it seems we can conjure up as many silly counter-examples as we like, such as:     If pigs can fly, then I can walk on water.   Though following the above truth table, the implication is that my ability to walk on water is true.  After considering it, it seems to me that $\implies$ is only meaningful when $P$ is true, then we can look at it in relation to $Q$. However, if $P$ is false, then we actually know nothing about the relationship between $P$ and $Q$. This would give a truth table of:  $$\begin{array}{ c | c || c | }   P &amp; Q &amp; P\Rightarrow Q \\ \hline   \text T &amp; \text T &amp; \text T \\   \text T &amp; \text F &amp; \text F \\   \text F &amp; \text T &amp; \text ? \\   \text F &amp; \text F &amp; \text ?  \end{array}$$  where the $?$ denotes that given $P$ we actually don't know anything about $ \implies $.  Thus. one way to clear this up would be to assume that $? = T$. Thus the vacuous truth is a "definition of convenience" in a sense.  The above is my take on the matter.  Could someone provide some clarification on the conditional logical connective? Permalinks: custom post type -> custom taxonomy -> post I am having trouble working with WordPress rewrite rules, and could use some help.  I have a custom post type called _shows_.  All shows have a single custom taxonomy category _show-category_. A _show_ will never have more than one _show-category_.  I would like my urls to route in this manner:  www.mysite.com/shows/  =&gt;  archive-shows.php  www.mysite.com/shows/%category%/ =&gt; taxonomy-show-category.php  www.mysite.com/shows/%category%/%postname%/ =&gt; single-shows.php   So as a real world example, lets say we have a _show-category_ "Foo" and a _show_ post titled "Bar" that has "Foo" as it's _show-category_. I would expect my WordPress app to look like this:  www.mysite.com/shows/foo/ =&gt; shows all posts under the foo category www.mysite.com/shows/foo/bar =&gt; shows the indivual post   I try to avoid plugins when possible, but am open to any solution.

How do I calculate my skill modifier? I'm trying to fill out the skills section on my first character, but when I look at the character sheets in the Starter Set as examples of how to make a character, the skills that are circled have higher modifiers than their Dexterity or Strength or whatever should make them.  I've filled out all skills but those. What do I add to the ability modifier to get those numbers?   My abilities are Strength 13, Dexterity 14, Constitution 11, Intelligence 15, Wisdom 8, and Charisma 8. Proficiencies are Arcana, Athletics, History, Investigation and Stealth. My saving throws are Strength and Dexterity.   I just started D&amp;D and have the Player's Handbook, DM's Guide, Monster Manual, and the Starter Set.

I recently got my Blacksmithing skill to 100. Now in the skills menu I can press space to make it Legendary, which will put it back to a skill level of 15 and reset my perks.
