I can't install Skype for Ubuntu 12.04. Downloaded from official Skype site, but cant install. All the time same mistake something about i386. What’s wrong?
Note: The legacy Skype for Linux application (v4.*) is now discontinued and was removed from Canonical’s partner repositories, so this question and its answers are obsolete. Please refer to  of our .  Skype 4.3 is just released with considerable improvements. As a regular Skype user I want to use the latest Skype on my Ubuntu 14.04, but there is no updates from Update Manager. Even in Skype website only Skype 4.3 is available only for Ubuntu 12.04. Is there anyway to use this latest Skype on Ubuntu 14.04 or how much we have to wait for the update?
R's lmer cheat sheet "A/An" preceding a parenthetical statement When a/an precedes a parenthetical aside (sometimes seen in informal/conversational writing), should the vowel rule depend on the first word in parentheses, or the next word in the "regular" flow of the sentence?     I need a (memorable) idiom (preceding an m word; use a)   or     I need an (memorable) idiom (preceding an i word; use an) I had an article, but I lost it.  It showed and described a couple of C/C++ tricks that people should be careful. One of them interested me but now that I am trying to replicate it I'm not being able to put it to compile.  The concept was that it is possible to change by accident the value of a const in C/C++  It was something like this:  const int a = 3;          // I promise I won't change a const int *ptr_to_a = &amp;a; // I still promise I won't change a int *ptr; ptr = ptr_to_a;  (*ptr) = 5;               // I'm a liar; a is now 5   I wanted to show this to a friend but now I'm missing a step.  Does anyone know what's missing for it to start compiling and working?  ATM I'm getting invalid conversion from 'const int*' to 'int*' but when I read the article I tried and it worked great. What are the differences between 2.5" and 3.5" hard disks? What does the 2.5"/3.5" value indicate? The thickness?  I want one of my friends to buy 1TB hard disk for me. I know I want a 1TB capacity and 7200rpm, but don't know how to choose between 2.5" and 3.5"; I am worried that the 3.5" drive may be physically too big.  Also, aside from the measurements, are there any other differences that may cause compatibility or usability concerns? Is there an easy way to 'break' the axis in a pgfplots environment? What I'm talking about is something like     Any minimal plot will do as an example...for example  \documentclass{minimal}   \usepackage{tikz} \usepackage{pgfplots}  \begin{document} \begin{tikzpicture} \begin{axis}[ymin=0, ymax=80] \addplot {x*0};  \addplot {x^2+50}; \end{axis} \end{tikzpicture}  \end{document}   For example, in the below plot,    I want to break the axis from around y = 10 to y = 40.   Any ideas? Does PGF have this functionality? A search for `break' in the manual doesn't yield anything. Why can I see the output of background processes? For example, when I type ping 8.8.8.8 &amp;, why can we see ping process working? And when I type find / -name '*test*' &amp; , it's also seen on monitor.  Why is that? Is it not really in background? I've heard it is possible to add tags to a file's meta data in OS X, and have Spotlight search through such tags.   In a nutshell, how would one access this feature in Finder &ndash; not Spotlight (Command+Space) &ndash; but the adding of tags themselves? Where are these tags stored?  Do they go in .DS_Store (I tend to delete those!) or elsewhere in the filesystem? Does this tagging mechanism work on removable drives?  What are the requirements? Does this tagging mechanism work over a network share?  I have some Windows SMB network shares at home that I frequently store files on.  Would it work on those or is another configuration required? Aside from Spotlight, are there any command-line tools for searching through or accessing the tag data for files?   Thank you! Given 3 distinct primes {$p,q,r$}, then $|G|=pqr \implies G$ not simple Work is not done by the magnetic field? I downloaded and installed version 0.29.2 of pokemon go on my Android phone, running lollipop. The app works fine most of the time, however, when I open the app without a WiFi connection (with mobile data on and working), it gets stuck on around 20% on the loading screen and doesn't budge.   The app works when I open it with a Wi-Fi connection and then leave Wi-Fi range or turn off Wi-Fi after it has passed the loading screen. However, the app will not pass the loading screen without WiFi. (Edit: Hotspots don't work either)  I've tried all the usual solutions - restarting, clearing cache, reinstalling, turning off and on mobile data. None of them work.  Any idea how I can start the app when I'm not in WiFi range? How to install networkx python in QGIS? How to install and how to compile networkx python on QGIS?  I always get an error that no module named networkx in the console of QGIS I copied the file networkx in C:\Program Files\Quantum GIS Lisboa\apps\Python27\Lib\site-packages and there are not change. Is there a way to exclude other particle systems from the effects of a Wind effect? I have a scene with a number of particle systems. I'd like to have a separate wind effect for my main scene and another for an extra: an emitter + wind-effect to blow leaves into my scene. I can't find any way to exclude, so here I am. At the very worst, I can just render the main scene and then render the wind effect and composite it, but I figured I'd check first. What is the problem that gets worse after you try to solve it? Example sentence - This problem is a _____ which gets complicated every time you try to solve it.   Is there such a word that represents a problem which will become worse if/when one tries to solve it?  Note - After seeing the comments and answers I'd like to add that this is not a can of worms or Pandora's box because it doesn't create a new problem but just worsens.   Example: Magic leaves protecting a fruit by enclosing it. Every time a leaf is touched, all the leaves close together further, that is more tight than before. When I have a query that checks if a column of type uniqueidentifer does not exist in a table that has a null value then I get no results back. If the subquery does not return a null it works fine and it only happens when using not in.   I know I can just do a not null check in my subquery, but I am curious why this does not work.  Query Example:  select a.guid from tableA a where a.guid not in (select b.guid from tableB AS b)   Working Test:  select 1 where newid() not in (select newid())   Broken Test:  select 1 where newid() not in (select null) 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. Use of quotes in GNU grep regular expressions What happens with No-Maj-Borns? In the Harry Potter series, lots of Muggle parents are introduced to the wizarding world because of their magical children. This is seen with Hermione's parents visiting Diagon Alley and various other moments.   In the 1920s USA world that has been created, rules about fraternising with No-Majs are very strict. Is there any evidence in any of the Pottermore articles or recently published film tie-ins which explain what happens with magical children born to No-Majs around this time? (Clearly certain events in the film suggest that they may have no procedure and that there can be side-effects of this - but I feel that those events must be rare!) How do I make Units efficiently? I just blew almost all my money on a really cool lookin' ship. How do I regain solvency without spending a lot of time fiddling around in my inventory?  At the moment I've found a sequence of steps that'll turn 50 carbon and 100 Plutonium into ~5000 Units (by creating Suspension Fluid and then turning it into Electron Vapor). Are there better recipes or sequences of recipes I should look for? Or should I just drop the whole thing and go mine a particular mineral? Overnight charges for brokers holding stocks? I'm trying to learn about stock markets. I eventually want to invest a small amount over a long period. Yet, I notice on a lot of broker sites that they tend to charge an overnight fee for any stocks held over night. I presume this is every night thereafter?  I just wondered because it seems like a wall when you want to let your stock price grow, and an overnight charge eats into this. or, is this only the case for "CFD" stocks? I'm confused.  Any help?  Cheers Is there a way to access QGIS plugins in Python?   I'd like to write a script to do some geoprocessing, and I'd like to use the clip, regular points and convex hull tools in fTools, as well as the Road graph plugin. The latter is probably a different can of worms because it is a C++ rather than Python plugin.
