Is it possible to create a Ubuntu Phone ROMs for Nokia X Family (launched in 2014)? It would be really helpful since Microsoft isn't giving any updates.
I would like to port Ubuntu Touch to a device that is currently not supported. What are the requirements for doing this and where do I begin?
It is an usual practice that any quantum field theory starts with a suitable Lagrangian density. It has been proved enormously successful. I understand, it automatically ensures valuable symmetries of physics to be preserved. But nevertheless the question about the generality of this approach keeps coming to my mind. My question is how one can be sure that this approach has to be always right and fruitful. Isn't it possible, at least from the mathematical point of view that a future theory of physics does not subscribe to this approach? Positioning of decorations on parallel lines I'm displayed three lines on a pgfplot. I want to show a marker for the slope of each line and the difference in height between lines.     I'm showing the slopes by adding triangles under the lines  (at a manual position) and placing an annotation inside the triangle (at a manual position). I'm showing the difference between the height of the lines by adding a brace manually as well.   How can I place the braces on the plot and anchor them at a certain point on each line? The triangles can be added at the end of each line declaration, but doing it like this is ok. The braces are put in place manually, which is not sustainable as I create more plots.   I want to avoid using xshift, yshiftand manual adjustment to put the braces,traingles and annotations in the right place. How can I do this?      \documentclass{article} \usepackage{pgfplots}  \pgfplotsset{compat=1.9}  \begin{document}   \begin{tikzpicture}[scale=0.45,trim axis left, trim axis right]     \begin{axis}[ylabel={$\hat{S(4)}$},xlabel={$S{^*}_{breakeven}$},ylabel style={rotate=-90},domain=1:25, legend style={legend pos=north west,font=\scriptsize}, legend cell align=left]  \addplot+[samples=200,mark=none]                                    {6.26 + 0.28*x} coordinate[pos=0.5](x) coordinate[pos=0.9] (y) (x)-| (y) node [midway,xshift=-0.6cm,yshift=0.3cm] {\footnotesize $Slope X$};;  \addplot+[samples=200,mark=none, dotted, thick]             {2.66 + 0.28*x}  coordinate[pos=0.3](a) coordinate[pos=0.6] (b) (a)-| (b) node [midway,xshift=-0.5cm,yshift=0.2cm] {\footnotesize $Slope 1$};  \draw [decorate,decoration={brace,amplitude=5pt,raise=4pt},xshift=4pt]  (225,107) -- (225,73)  node [midway,xshift=0.6cm] {\footnotesize $\beta_1$};  \end{axis} \end{tikzpicture} \end{document} Delete specific line number(s) from a text file using sed?

Crash or "segmentation fault" when data is copied/scanned/read to an uninitialized pointer Why does Worf want O'Brien to go to Minsk? How do they express the time, in American and British English? I don't know if this is a good question. But as far as I know, and as I do it, American English also say "after" other than "past" in expressing times.   For example, a quarter after six instead of, a quarter past six as in British English.  The other difference I know, so far, is that the British use dots to separate "hour" and "minute" in digital times like "08.35" while Americans use a colon e.g; "08:35".  So is what I know, so far, correct? Or are there any other differences that I don't know about? In the following code I loop through a map and test if an element needs to be erased.  Is it safe to erase the element and keep iterating or do I need to collect the keys in another container and do a second loop to call the erase()?  map&lt;string, SerialdMsg::SerialFunction_t&gt;::iterator pm_it; for (pm_it = port_map.begin(); pm_it != port_map.end(); pm_it++) {     if (pm_it-&gt;second == delete_this_id) {         port_map.erase(pm_it-&gt;first);     } }   UPDATE: Of course, I then  which I didn't think would be related but answers my question.

Dimensional Tolerance for US Standard NEMA 1-15 Plugs I am trying to find the dimensional tolerance on US electrical plugs. I have tried looking online, but I have only been able to find that they are called , and have found the picture below showing length and height for the male connector (but not width of the male prong), and I haven't been able to find dimensional tolerances anywhere.     I ask here because I'm assuming there's a US code that governs electrical plugs, but I can't seem to find the standard anywhere. If we set $A$ and $B$. Assuming that there exist an injective map from $A$ to $B$ and an injective map from $B$ to $A$. How to prove that there is a bijection between $A$ and $B$. After a lot of messing around today I curiously observed that $a^2+b^2$ is only divisible by 3 when both $a$ and $b$ contain factors of 3.  I am trying to prove it without using modular arithmetic (because that would be way too easy), but finding it very difficult to do so.  Is there an easy way to prove this without using modular arithmetic?  I am also interested in a more general statement.  Namely, I want to find the values of $Z$ for which $Z \mid \left( a^2+b^2 \right)$ necessarily implies that $Z \mid \gcd \left( a,b\right)$.  We know that $Z$ cannot be 5, because $3^2+4^2=5^2$.  More generally, if $Z$ is the largest element of a pythagorean triple then the above implication does not hold.

Area of the Limiting Polygon Start with an equilateral triangle with unit area. Trisect each of the sides and then cut-off the corners. In this case, we get a regular hexagon - see the picture below. Next, trisect each of the sides of the hexagon and cut-off the corners. This will give a dodecagon, but not a regular one.   Continue this process ad infinitum.  What is the area of the limiting "polygon"?  My first thought was that it would be the circle tangent to the midpoint of each side. However, by making some pictures, it becomes clear quite quickly that the limiting polygon is not a circle and, in fact, might perhaps be an ellipse. The problem with that is that while there is a unique circle passing through any three points in general position, I need five generic points to specify a conic.   Can anyone suggest any hints as to how to find the area? By "hint" I don't mean "what you think might work", I mean "what you have tried and you know will work". Thanks in advance. Are all simple left modules over a simple left artinian ring isomorphic? OpenSource ATI driver - Fan running at full speed all the time I know this is a common problem and have read other topics but couldn't resolve. Anyways yesterday I found a solution - I have 2 graphic cards (hybrid) and they were both on. So I turned one off and installed Jupiter for power management and from there on the fans were quiet and I was happy as hell.  However (:)), yesterday evening I also updated the system and the fan and it's noise came back.

SVN Error - Not a working copy Recently our svn server was changed and we did a svn switch.  Since the working copy had a huge amount of unversioned resources, the working copy got locked and we started switching folder by folder for all folders under svn, which works perfectly fine.  But at the top most level of the repository, when I try to update files, I get the svn: Working copy '.' locked error and cleanup is not helping either. When I do cleanup, I get errors like these - svn: 'content' is not a working copy directory  Fresh checkout is NOT an option at all. Are there any other ways to cleanup and release the locks and do the switch completely ?  EDIT:  The last paragraph in JesperE's answer     If you get a "not a working copy" when   doing a recursive "svn cleanup" my   guess is that you have a directory   which should be a working copy (i.e.   the .svn directory at the toplevel   says so), but it is missing its own   .svn directory. In that case, you   could try to just remove/move that   directory and then do a local update   seems to be the solution to the problem in the repository. I have identified those folders and did a fresh checkout of those specific folders alone and wow, the locks are released in the subsequent cleanup! Thanks a lot JesperE !!  But, I still cannot figure out the svn switch error which now reads something like,     svn: The repository at   'svn://repourl/reponame/foldername'   has uuid 'm/reponame', but the WC   has 'b5b39681-0ff6-784b-ad26-2846b9ea8e7d'   Any ideas ? Why won't SparseArray let me store values with the head List?
