How long should we wait for voting to close a question based on 'unclear what you are asking'?  Thanks !
Let's say that there is a question asked in a bad manner, in a way that the question is missing. For example the user shows the code and doesn't explain very well which is the problem.    Usually someone starts digging in the OP mind posting comments and asking him for details. It may happen that the question gets edited and the OP edits it to a valid question.    Do you usually give the OP time to edit the question or you immediately vote to close it?
Sending email in .NET through Gmail Instead of relying on my host to send an email, I was thinking of sending the email messages using my Gmail account. The emails are personalized emails to the bands I play on my show.   Is it possible to do it? 8.00GB RAM (3.22GB usable) in Windows 7 x64 I have set up Windows 7 Ultimate 64-bit on my PC. I have 8GB RAM and my BIOS states the correct amount (8192MB), but Windows (System Manager) says I have 8.00GB (3.22GB usable). give me a solution. I'm tried this: Run &gt; MSCONFIG, open the Boot tab &gt; click Advanced Options &gt; make sure that Maximum Memory but this wasn't helpful.

Adjectives order: opinion or size? speaking, opinion goes before size, i.e. opinion, size, age, shape, color, origin, material, purpose. However, I saw this example in Practical English Usage, third edition, page 12:      a big beautiful garden   Or you have probably heard the known expression  (BBW). What am I missing? Could I have a hint for testing the convergence of the following series please?  $$\sum_{n=2}^\infty\frac{1}{(\ln n)^{\ln n}}$$  I am very appreciative for your help. How do I get started with RAW photography? Having read about the benefits of shooting in RAW as opposed to JPEG (for example ), I'd like to have a go with it myself. However, I'm not really sure how to go about it.  I can turn RAW mode on in my camera (that's easy!), but what do I do with the files when I get them on to my computer? I presume I need to process them to get the RAW data into something that I can work with, but do I need a specific tool for my camera (a Finepix S5100), or will something like the GIMP do what I want? I'm also a little confused about how I then take advantage of the abilities that RAW gives me when I'm processing it on the computer — do RAW processing tools have more processing options than standard tools? Methods to find $\lim\limits_{n\to\infty}\frac1n\sum\limits_{k=1}^nn^{1/k} $ What would you suggest here?  $$\lim_{n\to\infty} \frac{1}{n} \sum_{k=1}^{n} n^{1/k} $$ How can I simulate a slow machine in a VM? In non-relativistic QM, the $\Delta E$ in the time-energy uncertainty principle is the limiting standard deviation of the set of energy measurements of $n$ identically prepared systems as $n$ goes to infinity. What does the $\Delta t$ mean, since $t$ is not even an observable? Sequence of tenses for facts irrelevant of the moment of speech Let's consider two sentences:     (1) I suggested that the word zeitgeist was of German origin.   (2) The lecturer said the Pluto's orbital period is more than 200 years.   In both cases, the facts are always valid and  irrelevant of the moment of speech and context. I've heard sequence of tenses is not required in such cases. Are past and present tenses interchangeable in both of them? Would it be correct to say:     (1) I suggested that the word zeitgeist is of German origin.   (2) The lecturer said the Pluto's orbital period was more than 200 years. $AB-BA=I$ having no solutions The following question is from Artin's Algebra.      If $A$ and $B$ are two square matrices with real entries, show that $AB-BA=I$ has no solutions.    I have no idea on how to tackle this question. I tried block multiplication, but it didn't appear to work. I'm taking Calculus II next semester so I don't have all the tools from it to back me up but something came up in a discussion this evening that asked me to prove that the following sequence converges. As I'm new to formal math I'm hoping someone can verify my proof, especially step $6$. I must prove that $$\lim_{n\to\infty}P_n=b$$ where $$P_{n+1} = P_n + \frac{b-P_n}{2}$$ $$P_0 = a$$ and $a,b \in \mathbb{R}$ such that $a&gt;b$ My proof goes as follows:   We must prove that $$\lim_{n\to\infty}P_n=b$$  That is, $\forall\epsilon&gt;0$ there exists a $\delta$ such that there exists an $n$ satisfying $$n&gt;\delta \iff b-P_n&lt;\epsilon$$  First, let us prove that $P_n$ is bounded by $b$ by contradiction. Let us choose an $i$ such that $P_i &lt; b$ and $P_{i+1}&gt;b$. Then we have $P_{i+1} = P_i + \Delta P$ where $\Delta P &gt; b-P_i$. but this is impossible because by the definition of the recurrence $\Delta P = \frac{b-P_i}{2} &lt; b-P_i$. Therefore, $P_i$ is bounded from above by $b$.  Additionally, it is trivial to show that $P_{i+1} &gt; P_i$.  With this in mind, choose an arbitrary $\epsilon$. We need to show that there exists an $n$ such that $P_n &gt; b-\epsilon$. Assume the contrary, that $P_n$ is bounded by $\epsilon$.  Using a similar argument to what which was used before, assume $P_n$ is bounded by $\epsilon$ and then there exists a $P_i$ such that $P_{i+1}\not &gt; P_i$. But this results in a contradiction with (4)  Therefore, $P_n$ is not bounded by $\epsilon$ and we have proved what we want to prove. I've been using gksudo nautilus and sudo nautilus through Alt+F2.   What's the difference? They look very similar! $C^2 $embedded in holder space? I have a question on Holder space.Is the space $C^2(\mathbb{R}^n)$ embedded in $C^{1,\alpha}(\mathbb{R}^n)$? I think in the bounded domain case, this should be true. But what if in the case where the domain is not bounded? Thanks for any hint! Use a execute command once How to perform orthogonal regression (total least squares) via PCA? I always use lm() in R to perform linear regression of $y$ on $x$. That function returns a coefficient $\beta$ such that $$y = \beta x.$$  Today I learned about total least squares and that princomp() function (principal component analysis, PCA) can be used to perform it. It should be good for me (more accurate). I have done some tests using princomp(), like:  r &lt;- princomp( ~ x + y)   My problem is: how to interpret its results? How can I get the regression coefficient? By "coefficient" I mean the number $\beta$ that I have to use to multiply the $x$ value to give a number close to $y$. Execute function when post is published I try to use this function i have created when a post is published for the first time.  function a_new_post($post){   $post_id = $post-&gt;ID;    if ( !get_post_meta( $post_id, 'firstpublish', $single = true ) ) {       // ...run code once       update_post_meta( $post_id, 'firstpublish', true );   } } add_action( 'draft_to_published', 'a_new_post' );   I can't see anything wrong with it, but when i try to create some sample posts i check the database and the field "firstpublished" has not been created.  Does anyone see anything wrong? Is it possible to save a Diablo 3 chat session or save some in game notes How can I make a .jar file executable? Last semester I picked up an algebra course at my university, which unfortunately was scheduled during my exams of my major (I'm a computer science major). So I had to self study the material, however, the self written syllabus was not self study friendly (good syllabus overall though).  The course was split up into 3 parts, group theory, ring theory and field theory. As a computer science major we only had to study the first 2.  Now that I passed the exam for this course I want to study the field theory part ( which covers Galois theory, etc).  So, now I want to ask whether any of you know any good books on abstract algebra, which lift off at basic ring theory and continue to more advanced ring theory and to finite fields, Galois theory, ...  Please keep in mind that I am not a math major, and that I would like books which are suited for self study (thus a lot of examples and intuition).  Thanks in advance!
