Im setting up ubuntu for the first time. I downloaded the version 12.  My wifi card is BCM4313 I read the manual on how to get the wifi up and running:   I downloaded the bcmwl-kernel-source and followed the instructions.  Here is the problem I cant activate the driver. I get an error: sorry installation of this driver failed check /var/log/jockey.log  and when I check it, terminal says no directory or file found.  I need some help, because I cant get internet on the wifi. I tried google already but it didnt give me any usefull answers.   many thanks in advance!
After installing Ubuntu 12.04 LTS on my HP Folio 13 I cannot get wireless to work. My kernel is 3.8.0-29-generic and my wireless module is a Broadcom BCM4313.  After running rfkill list all:  0: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: no 1: hp-bluetooth: Bluetooth Soft blocked: no Hard blocked: no 2: hci0: Bluetooth Soft blocked: no Hard blocked: no   The wired connection works fine. The driver activation for Broadcom STA wireless driver fails every time. in the log it says  FATAL: Module wl not found.

From other examples I suspect that the problem has something to do with dvips having trouble determining the bounding box for the image (compare with  -- although the solution given here, of using separate files for each image, is not a viable solution for me), but I have not been able to work out what the problem is.  Does anyone have any ideas? Is there any problem if the last name prints first than the first name on an air ticket? Is there any problem if the last name prints first then the first name in international air ticket? If $R$ is a local ring and $M$ and $N$ are finitely generated $R$-modules such that $M\otimes N=0$ then how does it follow from Nakayama's lemma that either $M=0$ or $N=0$?    This is an exercise in Atiyah and Macdonald. The part I could not show in the hints is $({M{\otimes}_R N)}_{k}=0$ implies $M_{k}{\otimes }_{k} N_{k}=0$, where $k=R/\mathfrak m$ and $\mathfrak m$ is the maximal ideal of $R$. Yesterday, I've listened to a song called "Fear not this night". I find the syntax unusual (as a foreigner, I have never encountered it). Is it the same meaning as "Don't fear this night" ? What's the slight difference between these 2 ?  Thank you for your time. Get a list of dates between two dates Using standard mysql functions is there a way to write a query that will return a list of days between two dates.  eg given 2009-01-01 and 2009-01-13 it would return a one column table with the values:   2009-01-01   2009-01-02   2009-01-03  2009-01-04   2009-01-05  2009-01-06  2009-01-07  2009-01-08   2009-01-09  2009-01-10  2009-01-11  2009-01-12  2009-01-13   Edit: It appears I have not been clear. I want to GENERATE this list. I have values stored in the database (by datetime) but want them to be aggregated on a left outer join to a list of dates as above (I am expecting null from the right side of some of this join for some days and will handle this). What are all the marriages and child relationships following the final chapter? In the last chapter of Naruto, some characters got married, and some of them had kids. What is the entire husband-wife-kids set? How can I delete my account? What is the lifespan of an SSD drive? Are SSDs comparable to HDDs for reliability and is there published research on this?  Also are all SSD manufacturers at a similar 'reliability level'? What are review tests (audits) and how do they work? Is there any substantial disadvantage to booking two one-way tickets, versus a round trip ticket?  Booking vacation travel with family of four for winter, from Northeast US to Mexico.  Round trip is pricy and no preferred travel times.  Two one ways is slightly cheaper with much preferred timing.      Different airlines there and back, both reputable national US carriers. Baryons have charges that are the result of a polynomial calculation of their building blocks (quarks)'s fractional charges. But what gives these quarks electric charges? What interactions do they have with photons? And what about leptons, like muons and electrons? How do they get their -1 charge? And then, how do positrons and anti-muons get +1 charge? Same goes for quarks: how does up-antiquarks get -2/3 charge? Or I may want to formulate my question this way:  How does any elementary particle interact with the EM-Force to get an electric charge? From the movies we know that Obi-Wan Kenobi delivered Luke Skywalker to Owen and Beru Lars to raise on Tatooine shortly after Luke was born at the end of RotS (Episode 3).   The next think we know is Luke running into Ben Kenobi during A New Hope.   There seems to be a hint that there was at least SOME communication between Kenobi and Lars family based on him telling Luke:     Your father wanted you to have this when you were old enough, but your uncle wouldn't allow it.   (though it's possible that was referring to Kenobi offering to leave the lightsaber to Larses at the same time he dropped off Luke)  I was wondering if any details of what transpired between Kenobi and Larses in the years between RotS and ANH were noted in any canonical works (of any canon, including EU books/games/comics/etc...)? Is it time to be rid of automatic down votes on certain closed questions? Show that the set of all $x$ such that $x \in P$ and $x \notin Q$ exists I have to show that set of all $x$ such that $x \in P$ and $x \notin Q$ exists. So, I think I have to assume that sets $P$ and $Q$ already exist. So, with that, I can use  . This axiom is $$ \forall w_1,\cdots, w_n \, \forall A \,\exists B \,\forall x \left( x \in B \Longleftrightarrow [ x \in A \wedge \varphi(x,w_1, \cdots , w_n, A)] \right) $$ So, I will let $\varphi(x, Q, P) = x \in P \text{ and } x \notin Q $. Also, I will let $A = P$ and  $w_1 = Q $. So using universal instantiation, I get the following $$ \exists B \,\forall x \left( x \in B \Longleftrightarrow [ x \in P \wedge \varphi(x, Q, P)] \right) $$ And using, existential instantiation, there exists a set $B$ such that $$ \forall x \left( x \in B \Longleftrightarrow [ x \in P \wedge \varphi(x, Q, P)] \right) $$ Using the definition of $\varphi(x, Q, P)$, this can be simplified as following $$ \forall x \left( x \in B \Longleftrightarrow [ x \in P \wedge x \in P \wedge x \notin Q] \right) $$ $$ \forall x \left( x \in B \Longleftrightarrow [ x \in P \wedge x \notin Q] \right)$$ $$ \forall x \left( x \in B \Longleftrightarrow x \in \{ x \,| x \in P \text{ and } x \notin Q \} \right)$$ Now, using , it will follow that $$ B = \{ x \,| x \in P \text{ and } x \notin Q \}  $$ And, since $B$ exists, this means that $\{ x \,| x \in P \text{ and } x \notin Q \} $ also exists. Is the proof good ? Find a real function $f:\mathbb{R}\to\mathbb{R}$ such that $f(f(x)) = -x$? What is the difference between a gameplay programmer and a game designer/developer? I see stuff like command 1&gt; out or with 2&gt;&amp;1 to redirect stderr, but sometimes I also see &amp;&gt; by itself, etc.  What is the best way to understand &amp; and what it means exactly? Can I fetch the value of a non-standard CSS property via Javascript? I am trying to read a custom (non-standard) CSS property, set in a stylesheet (not the inline style attribute) and get its value. Take this CSS for example:  #someElement {   foo: 'bar'; }   I have managed to get its value with the currentStyle property in IE7:  var element = document.getElementById('someElement'); var val = element.currentStyle.foo;   But currentStyle is MS-specific. So I tried getComputedStyle() in Firefox 3 and Safari 3:  var val = getComputedStyle(element,null).foo;   ...and it returns undefined. Does anyone know a cross-browser way of retreiving a custom CSS property value?  (As you might have noticed, this isn't valid CSS. But it should work as long as the value follows the correct syntax. A better property name would be "-myNameSpace-foo" or something.) How to guess a curve distribution from count data I have a sample composed by 2500 count data values. I've plotted in R the corresponding histogram and ecdf. I've run the One-Sample Kolmogorov-Smirnov test to check if the distribution is either exponential or poisson, but I got negative results.  Is it possible that the One-Sample Kolmogorov-Smirnov test, it's not the correct test to work with this count data.  What is the best way to identify a distribution for this kind of data? How can I install software or packages without Internet (offline)? I have a friend who has got a computer that is not connected to the Internet. Is there any way to install software offline easily?
