How to remove hyphens in signature in evolution mail
Evolution threads extra lines before signature
At the beginning of my document, I have created a counter using \newcounter. Over the course of the document, this counter is increases using \stepcounter. How can I display the final value of the counter in a place prior to the the final occurrence of \stepcounter, such as at the beginning of the document? Installing to SDCard by default I would like to know whether there is a way to tell Android to install applications on the micro SD card by default instead of having to download applications to internal memory first and then having to move them to the SD card manually.  Thanks If $n&gt;1$ is an integer, then $\sum \limits_{k=1}^n \frac1k$ is not an integer.  If you know , then you know there must be a prime $p$ between $n/2$ and $n$, so $\frac 1p$ appears in the sum, but $\frac{1}{2p}$ does not. Aside from $\frac 1p$, every other term $\frac 1k$ has $k$ divisible only by primes smaller than $p$. We can combine all those terms to get $\sum_{k=1}^n\frac 1k = \frac 1p + \frac ab$, where $b$ is not divisible by $p$. If this were an integer, then (multiplying by $b$) $\frac bp +a$ would also be an integer, which it isn't since $b$ isn't divisible by $p$.  Does anybody know an elementary proof of this which doesn't rely on Bertrand's Postulate? For a while, I was convinced I'd seen one, but now I'm starting to suspect whatever argument I saw was wrong. How do I play a YouTube video in the background on my iPad? What is the difference between a class and a set? I know what a set is. I have no idea what a class is.   As best as I can make out, every set is also a class, but a class can be "larger" than any set (a so-called "proper class").  This obviously makes no sense whatsoever, since sets are of unlimited size. It's not like you get up to 25 elements and go "oh, hey, sets are limited to a maximum of 20 elements, so we'll have to call this 25-element thing something else".  Does anybody know what the actual difference between a set and a class is?  Several people have pointed out that you can write paradoxes which involve sets. I get that. But where do classes come into the picture? The X button stopped working on one of my PS3 controllers. It's hardly through abuse, the controller isn't a year old and I don't play a lot.  The button doesn't stick, it presses like the others, only the system isn't aware that I'm using it. I tried resetting it with the tiny reset button in the back, to no avail.  What can I do? How to create complex conditional clauses / queries? I've been reading the documentatoin on  and also studied the api description for  and  but I fail to create a $query with 3 -&gt;conditions:   select all between 0 and 100 but exclude 23, 48 and 97 select also 107, 123, 126 and 128   That's what I have tried so far:  $query-&gt;db_or()   -&gt;condition('my_field', array(107, 123, 126, 128), 'IN')   -&gt;condition(db_and()-&gt;condition('my_field', array(0, 100), 'BETWEEN')                       -&gt;condition('my_field', array(23, 48, 97), 'NOT IN'));   But I get the following error:  PHP Fatal error:  Call to undefined method SelectQuery::db_or() in [... first line]   I've tried to play around with the syntax like that:  $query-&gt;condition(-&gt;db_or()   -&gt;condition('my_field', array(107, 123, 126, 128), 'IN')   -&gt;condition(db_and()-&gt;condition('my_field', array(0, 100), 'BETWEEN')                       -&gt;condition('my_field', array(23, 48, 97), 'NOT IN')));   But again getting errors like that:  PHP Parse error:  syntax error, unexpected T_OBJECT_OPERATOR, expecting ')' in [... first line]   I also tried working with variables:  $cond01 = array('my_field', array(107, 123, 126, 128), 'IN'); $cond02 = array('my_field', array(0, 100), 'BETWEEN'); $cond03 = array('my_field', array(23, 48, 97), 'NOT IN'); $db_and = db_and(); $db_and-&gt;condition($cond02); $db_and-&gt;condition($cond03); $db_or = db_or(); $db_or-&gt;condition($cond01); $db_or-&gt;condition($db_and); $query-&gt;condition($db_or);   But this again yields drupal errors like that:  SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Array' in 'where clause'   How to create a complex conditional database query with both AND and OR statements? I have a training set with about 3000 positive instances and 3000 negative instances. But my test data set is pretty much un-balanced. The positive set only has 50 instances and negative has 1500 instances.This causes the precision very low. Are there any approaches to solve this problem? I use SVM to build classifier. Feature request - links underlined How prove this diophantine equation $x^2+y^2+z^3=n$ always have integer solution show that: For any postive ineteger $n$,then the equation    $$n=x^2+y^2+z^3$$   always have integer solution   My idea: such as $n=1$,then we have $$1=0^2+0^2+1^3$$ $$2=0^2+1^2+1^3$$ $$3=1^2+1^2+1^3$$ $$4=2^2+0^2+0^3$$ $$5=1^2+2^2+0^3$$ $$6=1^2+2^2+1^3$$ $$7=2^2+2^2+(-1)^3$$ $$8=0^2+0^2+2^3$$ $$9=1^2+0^2+2^3$$ $$10=1^2+1^2+2^3$$ $\cdots\cdots\cdots$  But for  general $n$, How prove it? Assume  $$\lim_{n\to \infty}  (y_{2n} - y_n)=0$$  then  $$\lim_{n\to \infty} y_n$$  exists.  I know it's not true, and I can see a sequence that disprove that $(1,1,2,1,3,2,4,1,5,3,...)$ but I want a sequence that has formula.  hint/help?  thanks Virtual Box Toolbar Hidden. How to show? Encouraging people to explain downvotes Why is $\mathbb{Z}[\sqrt{-n}], n\ge 3$ not a UFD? I'm considering the ring $\mathbb{Z}[\sqrt{-n}]$, where $n\ge 3$ and square free. I want to see why it's not a UFD.   I defined a norm for the ring by $|a+b\sqrt{-n}|=a^2+nb^2$. Using this I was able to show that $2$, $\sqrt{-n}$ and $1+\sqrt{-n}$ are all irreducible. Is there someway to conclude that $\mathbb{Z}[\sqrt{-n}]$ is not a UFD based on this? Thanks. Mean of a Cauchy Distribution Are there any concrete rules that say which words (parts of speech) in a title should start with a capital letter?

Stack exchange badges It might be useful to encourage existing users of stackoverflow to cross pollinate other stack exchange sites.  While rep-sharing is not useful, as rep is meant to be a measure of expertise in one subject, badges may be one way to encourage participation across many sites.  This was triggered by seeing how few people actually had greater than 1k rep on all three main sites (SO, SF, SU) via Dennis Williamson's  app.  I had tried to do this by hand prior to the API under the assumption that many people would be answering questions on all three sites, but it turns out there are only 33 people, of all the users of stackoverflow, that have a 1k+ reputation on all three sites.  Over time it may be useful to provide badges that appear on all sites one is participating in that are awarded for extraordinary participation in the whole universe of Stack Exchange sites.  For instance, a silver badge might appear on all my profiles if I obtain 1k rep on 5 or more sites, and a gold badge if I have more than 3k rep on 5 or more sites.  I would hesitate extending this much past 5 sites as we don't want to encourage spamming questions and answers on sites where the user has little interest, but across the universe of stackapps I know I'm proficient or expert in at least 10 current sites, and while it's not a big nudge, the idea that I can get extra awards - especially ones that appear on all sites I'm in - would move me to participate a little more on sites that I am registered on, but don't visit regularly.    I expect, eventually as sites are launched, most users of any one site will have some interest or knowledge in at least 5 other sites.  This may provide the extra nudge some sites need to maintain an excellent rating in terms of usage. How is the skillset of an evolution being chosen? You may already know that if you catch two Pidgeys, they may have a different skillset.  I've also seen that evolving them from different skillsets will also create Pidgeottos with different skillsets.  Are those skills chosen randomly or do they follow a specific pattern? (Like Pidgey pattern 1 will always evolve into Pidgeotto pattern 1.)  If they are specific, is there a website to check for them? "GPT detected.
