Will my sony erricson xperia pro support Ubuntu?
With the announcement of the Ubuntu Phone OS I'd like to know what phone (and tablet) models are supported at this time.  Note from foss &amp; Oli: We are making this the master question for all future "Will this work on &lt;insert random tablet/phone/device here&gt;?!" questions

I cannot get heads nor tails of how to even start this let alone finish it Why are integer literals with leading zeroes interpreted strangely? Actual memory usage of a process The following are the memory usage of mysql and apache respectively on my server. As per the output of pmap say, mysql is using about 379M and apache is using 277M.   [root@server ~]# pmap 10436 | grep total  total           379564K  [root@server ~]# pmap 10515 | grep total  total           277588K   Comparing this with the output of top, I see the values are almost matching.    PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND 10515 apache    20   0  271m  32m 3132 S  0.0  6.6   0:00.73 /usr/sbin/httpd 10436 mysql     20   0  370m  21m 6188 S  0.0  4.3   0:06.07 /usr/libexec/mysqld --basedir=....   Now these values definitely are not the current memory usage of those two processes, since if it were it would've exceeded the 512M ram on my system and I understand the fact that these are the size of the pages assigned to these two processes and not really the size of the memory actively used by them. Now, when we use pmap -x, I see an extra coloumn Dirty which shows far less memory usage for the process. As seen in the example show below, the Dirty coloumn shows 15M as opposed to 379M in the first coloumn. My question is: Is the value under coloumn Dirty is the 'real' amount of memory actively used by that process? If its not, then how can we find out the real memory usage of a process? Not ps and top for the same reasons above. Do we have anything under /proc that will give this info?

I recently upgraded to windows 10 on my daily driver laptop and I have liked it so far except for one thing. Randomly the windows menu decides to stop working when I press the windows key or I press the button in the corner. Has anybody else experienced this problem? Solutions?  Thanks!

Why do I get more satisfaction out of participating in SO than out of my job? Alternatively, are there good ways to get more satisfaction out of my job, possibly by leveraging my participation in SO? Sometimes writing braces and omitting them produces the same result:  \tilde{\psi}  \mathrm{e}^{\mathrm{i} \pi}   vs  \tilde \psi   \mathrm e^{\mathrm i \pi}   Or (taken from Werner's comment below)   \frac{1}{2} vs \frac12   If that's the case, how bad for the quality of my code is omitting them? Of course, if one compiles a pair of formulas, there is no difference. But, since I ignore how TeX works, my point is: if one writes long codes with these habits,   doesn't TeX go somehow crazy because I'm not writing as it expects?   For instance, does it have any effect on how fast are long documents compiled? Any reason to keep them? Show that $S$ is compact. Let $A \in M_n(\bf C)$ and let   $S=\{ A \in M_n(\bf C) : A=A ^*$ and  $\rho (A) \leq 1 \}$, $\rho(A)$ denotes spectral radius of $A$.     Show that $S$ is compact subset of $M_n(\bf C) \cong \bf C^{n^2} $ with usual topology.    $S$ is subset of $\bf O_n(C)$ which is compact so I think its enough to show that $S$ is closed.Please help. As the title says, I'm wondering if there is a continuous function such that $f$ is nonzero on $[0, 1]$, and for which $\int_0^1 f(x)x^n dx = 0$ for all $n \geq 1$. I am trying to solve a problem proving that if (on $C([0, 1])$) $\int_0^1 f(x)x^n dx = 0$ for all $n \geq 0$, then $f$ must be identically zero. I presume then we do require the $n=0$ case to hold too, otherwise it wouldn't be part of the statement. Is there ay function which is not identically zero which satisfies $\int_0^1 f(x)x^n dx = 0$ for all $n \geq 1$?  The statement I am attempting to prove is homework, but this is just idle curiosity (though I will tag it as homework anyway since it is related). Thank you! How can I start Hoard of the Dragon Queen with 4th level characters? I'm pretty new to DM'ing and was just wondering if there would be a way to start the hoard of the dragon queen adventure with a group of 4th level characters?  There don't really seem to be any modules for that level range yet.  We just finished a short module that took our party to level 4, but id really like to play through this adventure because it seems awesome. Also I couldn't really find any other ones that start around that level so rather than re-roll characters we'll just start a little of the way in.

A question in Complex Analysis $\int_0^{2\pi}\log(1-2r\cos x +r^2)\,dx$ My problem is to integrate this expression:  $$\int_0^{2\pi}\log(1-2r\cos x +r^2)dx.$$ where $r$ is any constant in $[0,1]$.  I know the answer is zero. Can you explain you idea to me or just prove that? Maybe you will use the "Cauchy integral theorem ". I am using Google Spreadsheets to create a matrix (time/activity) as a daily schedule for staff to sign into.  Is there a formula to calculate the number of cells in a column that are shaded (or not shaded) a certain color?  For example: 20 of the cells are gray and 31 are not gray (shaded any other color) and instead of manually counting them, it calculates this at the bottom of reach column. Prove that there exists such a set of $n$ positive integers Prove that for any positive integers $m$ and $n$ , there exists a set of $n$ consecutive positive integers each of which is divisible by a number of the form $d^m$, where $d$ is some positive integer not equal to $1$.
