Is there any advantage to naming function declarations?
var functionName = function() {} vs function functionName() {}
How can I obtain the limit of the series     $$\sum_{n=1}^{\infty} \frac{2^{[\sqrt{n}]}+2^{-[\sqrt{n}]}}{2^n}$$   Where $[\ \ ]$ is . I'm currently building a town in Minecraft Pocket Edition and I'm wondering how many blocks long and how many blocks wide the world is. Propose Newbie-Overflow site or section Because the perl section is looking like that right now. I believe that Stack Overflow is going out of it's charter in becoming a newbie FAQ when as far as the original reasoning it was meant to be something along the lines of an expert site.   is a good example of what I mean in Perl. It probably could be closed because it's a duplicate, or some other reason.   I would also like to indicate that I don't hold back answering newbie questions. It's just when I think of an obscure "stack overflow" error that's beating you some 3 am close to deadline, that's not "Howcum Perl print ..." and follows with something that causes a vast majority of Perl programmers to say oops, because they know exactly what's going on.   So the proposal is   A new site. "Move to Newbieville" A new "section" A new status somewhat similar to Closed ("Newbied") but still can be updated all the same as an open question.   I'm not against giving some newbies an assist, but I feel a FAQ for rank newbieism is not something that SO started out to be, based on the original concept of a Expert Site.   Including comment to Gnoupi:   I said nothing about making newbies unwelcome. Like I said. I answer them--heck, I think I've even answer homework questions. I've answered on the vague impressions that I can glean from posts that have 4 close votes. It can even lead to avoiding downvoting or yelling at newbies by more established curmudgeons if there is a special action you can do to gently inform newbies that this is a real newbie question.  However, you have to know that to some people newbies are already unwelcome. There is a site ethic, but the individual is also going to decide how much they welcome newbies. And people do post RTFM answers already.   Anyway, I'm one vote away from a peer pressure badge it seems. (Nope, nailed it.)    EDIT  For somebody jumping to the conclusion that I'm hostile to newbies:  just earlier The situation is my  has been enchanted with .

Import a module from a relative path How can I install Broadcom Wireless Adapter BCM4352 802.11ac PCID [14e4:43b1] (rev 03) on fresh install of Ubuntu 14.10 (Utopic Unicorn)? I have a brand new Dell XPS 15. I   dual boot it with Windows 8.1 and  Ubuntu 14.10  The Wireless Network Adapter is Broadcom BCM4352 802.11ac with PCID [14e4:43b1] (rev 03).  The 4352 is not included in the list for installation via bcmwl-kernal-source file. I tried this anyway, but the Terminal command led to the file starting to install, but then stopping. Sometimes I get a permission denied error message.  As a result of reading and trying all advice from forums I have decided to completely reinstall Ubuntu 14.10. I doubt my particular Broadcom Wireless Card has no support on Ubuntu 14.10?    Edit:  The advice of Chili555 worked. I now have working wifi using Broadcom Wireless Adapter BCM4352 802.11ac PCID [14e4:43b1] (rev 03) Electromagnetic Tensor in Cylindrical Coordinates I understand that the  is given by  $$F^{\mu\nu}\mapsto\begin{pmatrix}0 &amp; -E_{x} &amp; -E_{y} &amp; -E_{z}\\ E_{x} &amp; 0 &amp; -B_{z} &amp; B_{y}\\ E_{y} &amp; B_{z} &amp; 0 &amp; -B_{x}\\ E_{z} &amp; -B_{y} &amp; B_{x} &amp; 0 \end{pmatrix}$$  where $\mu$, $\nu$ can take the values {0,1,2,3} or {$t,x,y,z$}.  So, for example  $$F^{01}=F^{tx}=-E_x$$  My question is, what would the following expression be?  $$F^{t\rho}=?$$ or $$F^{z\rho}=?$$  where $\rho=\sqrt{x^{2}+y^{2}}$ is the radial coordinate in ?  And more generally, how can we construct the Electromagnetic Tensor in cylindrical coordinates? Where $\mu$, $\nu$ now take the values {$t,\rho,\varphi,z$}.

When taking landscape photos, I often struggle with dynamic range. I have either a burned out skies or landscapes are too dark.  Now I'm reading  that some cameras can take 3 pictures with different exposures, and combine them automatically to one image with higher dynamic range.   So my question is, which cameras have this feature? When should we consider a dataset as imbalanced? I'm facing a situation where the numbers of positive and negative examples in a dataset are imbalanced.  My question is, are there any rules of thumb that tell us when we should subsample the large category in order to force some kind of balancing in the dataset.  Examples:   If the number of positive examples is 1,000 and the number of negative examples is 10,000, should I go for training my classifier on the full dataset or I should subsample the negative examples? The same question for 1,000 positive example and 100,000 negative. The same question for 10,000 positive and 1,000 negative. etc... How to set a command block with a command inside using the setblock command Does someone know how to set a command block with a command inside using the setblock command?  I have created this code /setblock &lt;x&gt; &lt;y&gt; &lt;z&gt; command_block {TileEntityData:{Command:"testfor @p[_=1]"}} but it doesn't works.  Do someone know how to do that?

I am trying to install chrome browser via command line.  I tried this:  $ apt-cache search chrome browser   The results show that the proper term is "chrome-browser," so I tried that:  $ sudo apt-get install chrome-browser   And then "Y" for the Y/n question.  But the installation threw errors.  Does someone see anything wrong with the commands I issued? Do electrical devices "take what they need" One concept of electronics I have a hard time understanding is if things like motors, actuators, solenoids etc. use as much power as they need or what you give them.   If a motor needs 12 volts and 500ma and I supply it with 12 volts and 3000ma will it only consume 500ma? Also, if I supply it with 15volts and 500ma what will happen?   It seems logical that an LED and a DC motor are way different when it comes to requiring/using electric where as an led has to be completely regulated and (I assume) a DC motor doesn't.   Is my understanding wrong? Inheriting Options? Which gears combinations shouldn't be used? Is there any general rule or recommendation to avoid usage of certain gears combinations (for 2xN and 3xN gears systems)? Do they differ for mtb and road bikes?  I know that it's recommended not to use biggest front chainring with big chainrings on cassette (and opposite) because parts will wear faster and I will loose a bit of pedaling efficiency, but I'm not sure, if I should avoid 2 or 3, or even more biggest (smallest in opposite case) chainrings on cassette. Let $A \in {M_n}$ is nonsingular and each eigenvalue of $A$ is either $+1$ or $-1$.Why $A$ is similar to ${A^{ - 1}}$?
