• I Can't install Skype on Ubuntu 12.04 x64. Can someone help me?

  - by Matheus

  I'm having a trouble when trying to install Skype on my Ubuntu 12.04.1 x64. My notebook have compatible hardware with Ubuntu. My previous OS installed on this machine was the Ubuntu 12.04 x64 and Skype was working great, but I got a formatation and I installed the New ubuntu 12.04.1. When I try to install by the Ubuntu software Center, or by the sudo apt-get install skype, I get this error message (in Portuguese) : "Os pacotes a seguir têm dependências desencontradas: skype: Depend: skype-bin E: impossivel corrigir problemas, você manteve (hold) pacotes quebrados." Something like i have the skype-bin package missing (or broken). I can't find it on Software center. I tried to install it by downloading a deb package with the skype-bin package but it ask for a lot another packages! I tried install the .deb package from the official Skype site, but I got the same error! Any Help? Sorry about my bad English, I'm Brazilian

• What effect does using itemprop="significantLinks" on anchors have for SEO and what is the ideal use?

  - by hdavis84

  I'm practicing application of microdata via http://schema.org. Anyone who's browsed the documentation there knows that there's a lot of need for improvement for more clear understandings on use for each property. My question on this post is more about the "significantLinks" property and how it effects SEO for on page, in content anchored text. Does anyone have any more information regarding whether its good to use for link optimization? I understand what schema.org means that it's to be used on "non-navigational links" and those links should be relevant to the current page's meaning. But will using this property hurt SEO or make SEO better for each page?

• Serverless Web Application

  - by Andrea Di Persio

  In my company we work on a software that produce reports in html format. My bosses love the fact that static html pages can be moved across computer simply by moving/copying a folder and no web server is involved, so the customer only need a browser. The problem is that they asking me to implement a lot of feature which is very hard to implement properly and in a clean way without an application server. Frames cross domain problem, the impossibility to work with GET and POST data, no URLs routing...is very hard to work with this limitations. Anyone had similiar experience and wants to share their tricks/suggestion ? Do I need to tell my boss 'there is no future without a web server'? Regards.

• How can I reconnect to a ssh session after a broken pipe?

  - by Chauncellor

  So I was running apt-get upgrade on a server when the router decided it had been too long since it last made me angry: It dropped all connection. Moral of the story is to use screen a lot when you're on a bum router. Anyway, I logged back in and found in htop that the process was still hanging there, still waiting for my Y/n to upgrade (hadn't hit it yet, luckily). Is there any way I can reattach to a session that had been broken off? I ended up just killing it since it wasn't in the middle of package management but it would be great to know for future reference.

• Just wondering about "Do-It Yourself Apps" on the internet versus apps written by us developers

  - by user657514

  Hi, I have been doing Objective-C programming over the past few weeks, and I have learnt a lot. However, I see that there are other Web-companies offering services to consumers directly from their website that allow consumers to create their apps through a point and click and drag features without any code. Clearly they are more cost effective and fast than having a developer write an app. I was wondering if there are any advantages then of having a developer build an app for someone, other than the obvious advantage that its got a custom look and feel. Could someone please clarify, since Im new and would like to evaluate whether it is worthwhile spending time towards learning a whole new development environment when someone could just use a webservice to make an app for multiple platforms Thanks

• Mobile Compatibility: traditional website look vs native application ?

  - by Siddiqui

  I have a question related to mobile compatible websites, I have seen two type of websites One in which they adopt traditional website look and adjust website according to mobile screen, if they have lot of information which can not be adjust according to screen then they expand the height of page, so that user can scroll the page to see more information... In the second approach they used native application look means use navigation-bar, tab-bar, tool-bar, scroll-view just like in native applications. Height and width of page adjust according to screen size, if they have more information then they use scroll-view etc... My question is: which approach is better then other, in which approach you feel more comfortable to use website.

• Strange behaviour when screencasting

  - by Luis Alvarado

  Since an update I did yesterday I am not able to screencast any video using Kazam, Recordmydesktop or even ffmpeg/aviconv. After the upgrade to some libraries (A normal update that showed in Update manager) the problem was this: When doing the screencast, scrolling inside an Apps window like Firefox, Chrome or Gedit is not shown. The video only shows the last image it recognized before I started scrolling. For example with Gedit, I have a lot of text on it and when I start to scroll down, the video only shows what I had in the beginning while I listen to myself talk about what is in the rest of the file (Which is not shown in the video). When opening a window, for example again Gedit or Chrome it might not show in the video, it will just show the desktop without the window opened. I do not see any error with dmesg, syslog or others. What can I check to debug this problem?

• A peculiar issue with nm-applet

  - by montreux

  There is a somewhat strange error that I've noticed with my gnome sessions. It's not a problem that causes a lot of trouble, but at times it becomes annoying. Anyway, here it is: when I fire up gnome-session-fallback (which is the main one I use), the network applet doesn't run with root permission. Here is what it looks like http://i.imgur.com/8kc7Vrd.jpg . On the other hand, here is what the regular gnome session looks like http://i.imgur.com/wfkkE3E.jpg . From the regular session I can easy edit and add networks, but from fallback session I cannot add/edit anything, or turn off/on the wireless or networking. Any ideas?

• What does well written, readable tests look like?

  - by Industrial

  Doing unit testing for the first time at a large scale, I find myself writing a lot of repetitive unit tests for my business logic. Sure, to create complete test suites I need to test all possibilities but readability feels compromised doing what I do - as shown in the psuedocode below. How would a well written, readable test suit look like? describe "UserEntity" -> it "valid name validates" ... it "invalid name doesnt validate" ... it "valid list of followers validate" ..

• Should I fork for a major re-write that uses a small amount of the original code?

  - by It'sNotALie.

  I'm writing a library. It's a completely rewritten version of another one, to suit my needs (PCL compatibility, mainly). However, the API will be completely rewritten, as I'll need to change a lot of stuff around for PCL compliance. Also, as it is a rewrite, I won't be able to just start from the library and just change it bit by bit, as I typically see with forks. I tried that, but it just didn't work. So what should I do? Should I fork here or should I make a new library?

• How do I find out on which partition is my Windows?

  - by Perlnika

  I have fully functional Windows and Ubuntu that is broken (I accidentaly broke it) and want to do reinstall. With Live-CD, I can see: 3 NTFS partitions, one ext4 and one unknown. How do I find out which partitions belong to Windows? I thought that I might delete everything that wasn't NTFS, but I was afraid. Now I am using: Install Ubuntu alongside them option, but I guess that this will leave my broken Ubuntu untouched. So, again, I need to know which partitions to merge (perhaps add partitions of broken Ubuntu to new Ubuntu?). Please, how can I learn how my system is divided? Thanks a lot.

• Is there an opposite for the term "Backporting"?

  - by Avian00

  As I understand, the term "Backporting" is used to describe a fix which is applied in a future version which is also ported to a previous version. Wikipedia definition is as follows: Backporting is the action of taking a certain software modification (patch) and applying it to an older version of the software than it was initially created for. It forms part of the maintenance step in a software development process... For example: A problem is discovered and fixed in V2.0. The same fix is ported and applied to V1.5. What is the term when this is done in the opposite direction? The problem is discovered and fixed in V1.5. The same fix is ported and applied to V2.0. Would the term "Backporting" still apply? Or is there a term such as "Forwardporting" (which amusingly sounds a lot like "Port Forwarding")?

• Ubuntu 12.04 intermittently fails to wake up from sleep

  - by stacksia

  When I put my Ubuntu 12.04 machine into sleep, sometimes on waking up, it fails, logs me out, and takes me back to login screen. When I log back in, it tells me some unexpected error happened, but it fails to let me report the bug. This has started to happen recently, but I don't know what triggered it. uname -a Linux [name] 3.2.0-30-generic #48-Ubuntu SMP Fri Aug 24 16:52:48 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux The issue seems similar to Xorg intermittently restarts after suspend. But in my case I am not sure if it is a Xorg issue. I looked at xorg logs, but didn't notice anything indicating an error. I know I am not providing a lot of info, but I am not sure where (e.g. which log files) I should seek for more info.

• Acer AO722 flickering screen

  - by user1131702

  The screen on my Acer Aspire One netbook (AO722) flickers for a few minutes when Ubuntu awakens the screen after a period of inactivity. I am pretty sure this is not a hardware issue, as I never see this problem in Windows and both of my Acer netbooks exhibit the same problem. I see the flickering in all recent versions of Ubuntu -- 11.10, 11.04, and 10.10. Surprisingly I haven't been able to find a lot of information about this problem online. I believe the video card in this netbook is Radeon 6290 paired with AMD C-60. I am using the default open source video driver. Would appreciate any tips on how to get rid of the flicker. Thanks!

• About to graduage from good school without any progamming skills

  - by newprint

  Not sure if it is good place to ask this question, but found this section to be suitable. I am about to graduate from good school (in the US) with Computer Science degree, having good grades and high GPA. I have no freaking clue how to write a good program, how to properly test it... nada, zero. We were never been tough how to write software. Ye, sure the Comp. Architecture class is important, and I can tell you a lot about how MIPS processor works, and I can tell you about Binary Trees and Red-Black Trees and running time of operations in Big Oh, but it has nothing to do with programming in "real" life. For god sake, none of my classmates know how to use STLs or write templated code !!! To be honest, I found that many of my classes to be waste of time. What should I do ? How to step into real life and learn how to program ?

• How to design 2D collision callback methods?

  - by Ahmed Fakhry

  In a 2D game where you have a lot of possible combination of collision between objects, such as: object A vs object B = object B vs A; object A vs object C = object C vs A; object A vs object D = object D vs A; and so on ... Do we need to create callback methods for all single type of collision? and do we need to create the same method twice? Like, say a bullet hits a wall, now I need a method to penetrate the wall for the wall, and a method to destroy the bullet for the bullet!! At the same time, a bullet can hit many objects in the game, and hence, more different callback methods!!! Is there a design pattern for that?

• How to debug Android App Eclipse?

  - by user2534694

  Ok. So while this isnt a programming question. I wanted to know how do people debug apps? How do you view log cat, and where these exceptions are thrown etc? And do I need to run the app on the emulator to see all the stuff, or is there a way to view this after running the app on my phone(while not being connected to the computer) Links to plugins and tips would be really helpful, as im gonna start work on my next game, and while the first one works fine, had a lot of problems while debugging.

• How can I explain object-oriented programming to someone who's only coded in Fortran 77? [closed]

  - by Zonedabone

  Possible Duplicate: How can I explain object-oriented programming to someone who’s only coded in Fortran 77? My mother did her college thesis in Fortran, and now (over a decade later) needs to learn c++ for fluids simulations. She is able to understand all of the procedural programming, but no matter how hard I try to explain objects to her, it doesn't stick. (I do a lot of work with Java, so I know how objects work) I think I might be explaining it in too high-level ways, so it isn't really making sense to someone who's never worked with them at all and grew up in the age of purely functional programming. Is there any simple way I can explain them to her that will help her understand? Thanks for the help in advance.

• configuring separate X screens instead of TwinView

  - by fimre

  My Sony Vaio laptop is connected to an external Samsung monitor and my nVidia driver is configured in TwinView mode. Everything is OK with this, however, I can not adjust my displays individually so at the moment my external display is a little bit darker which disturbs me a lot. I tried the Separate X Screen mode but after restart, my laptop display was white with a black x sign mouse pointer and the external display normal desktop. Is it a bug or something I missed? The idea is that using Separate X Screen mode, I could adjust my displays individually. I would really appreciate someone would guide me out of this situation. Thanx in adv..

• How can I generate Sudoku puzzles?

  - by user223150

  I'm trying to make a Sudoku puzzle generator. It's a lot harder than I expected and the more I get into it, the harder it gets! My current approach is to split the problem into 2 steps: Generate a complete (solved) Sudoku puzzle. Remove numbers until it's solveable and has only 1 solution. In step 1, since I'm using a brute force methods, I'm facing some run time issues. Is there an optimal way of filling in a complete Sudoku puzzle? In step 2, what kind of algorithm should I use to "puzzlize" a solved sudoku?

• Can I get some advice on graphics cards please?

  - by Victor9098

  I know that Steam for linux is on the way and have been seen a lot of games appearing in the Ubuntu Software Centre of late but my system lacks a decent graphics card and was hoping I could get some recommendations. The desktop is a Packard Bell Imedia S1800 (or Imedia D3526 UK) with the following specs; Memory: 3.8 GiB Processor: Pentium(R) Dual-Core CPU E5800 @ 3.20GHz × 2 The system lists the graphics as 'unknown', though I think its just an integrated Intel card From what I can see there is a free PCI-E x16 slot. Any advice would be great, thanks!

• Adding users to multiple/all sites in Google Webmaster Tools?

  - by Christian

  I didn't find an answer to this, but maybe I didn't use the right terms for my search. So I'm sorry if this is a duplicate. Anyway, my situation is this: the company I work at manages a lot of sites (100+), and we've recently put them all into Google Webmaster Tools under my Google account, which was tedious enough. Now two coworkers are supposed to be added as users for each site, so they can see the data and manage stuff there as well. But I can only find an option to add users for a single site, not for all sites that are currently associated with my account. Do I really have to go through more than a hundred sites one by one and add the two users to each of them, or is there some way to add both users to all/multiple sites at once?
