• How do I fix gnome shell themes?

  - by Chris

  This is my fifth full format and install of Ubuntu in under a month. I finally have my Gnome 3 desktop working again, but again, the Gnome shell themes is not select-able. I have asked the question of how to fix this common issue before, but I have seen no positive resolution. Does anybody know of a simple fix? This is a common issue and I have seen hundreds of postings related to it, but other users only seem to get half-way answers also and it goes unresolved. Would it be advisable to completely purge Gnome desktop and reinstall? If so how would I do this? I cannot use any extensions if the shell is not working, so I am desperately seeking resolution for the issue. Thanks in advance.

• Mouse Not Working on Boot

  - by user88043

  I have seen several topics regarding this situation, but none of them truly address my issue (that, or there are no answers that solve the issue.) Upon booting into Ubuntu 12.04.1 x64 my mouse wired USB mouse (Steelseries Sensei if that makes any difference) either doesn't work or stops working immediately after the grub menu, prior to the login screen appearing. The cursor is present, but obviously not reactive to any mouse movement; even the LED on my mouse turns off (or fails to turn on.) The only way I've found to activate the mouse is to restart the computer, and even then it's 50/50 at best as to whether or not the mouse will be powered. This issue has never happened in Windows 7, so the mouse is operating properly on the hardware and connection side. Forgive my ignorance of Ubuntu (and Linux in general), but I was hopeful that someone would have some suggestions, or could at least instruct me on what to check in order to provide any further information for diagnoses.

• How would you want to see software intellectual property protected?

  - by glenatron

  Reading answers to this question - and many other discussions of software patents - it seems that most of us as programmers feel that software patents are a bad idea. At the same time we are in the group most likely to lose out if our work is copied or stolen. So what level of Intellectual Property Protection does code and software need? Is copyright sufficient? Are patents necessary? As software is neither a physical object nor simple text, should we be thinking of a third path that falls somewhere between the two? Do we need any protection at all? If you had the facility to set up the law for this, what would you choose?

• audio controls in xfce 4.8

  - by Peter

  I am seeing several questions similar to mine, but none of the answers are sufficient. I am pretty green with Ubuntu, so here goes: I was just automatically upgraded to xfce 4.8 for Ubuntu studio. The volume control no longer works in my panel. When I launch 'mixer' I don't see any settings, either. When I try to run "linux audio configuration" I get an error: JACK can only be configured with a loaded and stopped studio. Please create a new studio or load and stop an existing one. I understand that I can change the volume using command line, but I can't understand why I got upgraded to something that fails on basic features. I much less likely to recommend ubuntu to others as a result. thanks!

• Need a graphical renaming tool which can rename files recursively

  - by user37991

  ATM I am forced to use freeware in Windows to rename SOME Linux data files. Linux also creates files like "Filename.ext" as being different to "filename.ext", and !@#$hg".ext ... which cannot be recognized by Windows. "pyrenamer" ... mentioned in another answer cannot auto-rename more than the one immediate folder. I use Ubuntu, not ARCH linux, because I am not CLI. Despite some answers here (designed by and for CLI programmers), how can Ubuntu GUI (not CLI) do file renaming? BTY: in ONE folder only, THUNAR is far better than silly pyrenamer. But Thunar cannot auto-rename recursively.

• GLIBC_2.8 not found

  - by Thomas Nilsson

  As a newbie I seem to have messed up my upgrade leaving my system in a very unstable state. I attempted an upgrade from 8.04LTS which ended in an error about libc and kernel upgrades. I tried to upgrade the kernel but am now unsure if that worked, because when I retried my dist-upgrade there was a lot of errors about pre-dependencies and leaving packages un-configured. Now I have a system that answers almost every command with: /lib/libc.so.6: version `GLIBC_2.8' not found (required by /lib/libselinux.so.1) I probably should try a complete re-installation, but I'm investigating if there is any possibility of getting a working glibc so that I at least can have some commands working to ensure that my backups are recent etc. before doing the clean install. not even 'ls' works without saying "glibc_2.8 not found".

I installed "fresh" O.S. few days ago. Ubuntu is updated and has many Gigabytes of disk memory available. Please help me and my unfortunate O.S. Thank you for all answers.

• which is the best CMS for building a Video tutorial website? [duplicate]

  - by Rajesh Sankar R

  This question already has an answer here: How to choose a CMS system for a small web site? 4 answers I am planning on setting up a website where I will be posting "how to or training videos" for various softwares. There will be several training videos under a single topic. And there will be several topics under a single software training. Similar to lynda.com but in a small scale. Can you suggest me a CMS for the job? Initially I am planning on hosting videos on YouTube and linking them to my website. But, I will be moving to my own hosting later on. It must be customizable, scalable, and most of all OPEN SOURCE

• Which version of Ubuntu is recommended for app developers?

  - by Wes

  I've searched around Ask Ubuntu and the App Developer site, but I can't seem to find the answers to my questions. I'm wanting to get back into programming, and I'd eventually like get into app development for Ubuntu, but I'm not sure where to get started. Which version of Ubuntu is currently recommended for app development, especially for those wanting to publish their apps to the Software Centre? Should app developers use the current LTS release, or, can any of the new releases be used? Should developers use the 32-bit or 64-bit edition of Ubuntu, or does this not matter? What effect would the above choices have on the eventual publication of an app? I'm truly sorry if this has been covered elsewhere. Cheers Wes

• What happened this type of naming convention?

  - by Smith

  I have read so many docs about naming conventions, most recommending both Pascal and Camel naming conventions. Well, I agree to this, its ok. This might not be pleasing to some, but I am just trying to get you opinion why you name you objects and classes in a certain way. What happened to this type of naming conventions, or why are they bad? I want to name a struct, and i prefix it with struct. My reason, so that in IntelliSense, I see all the struct in one place, and anywhere I see the struct prefix, I know it's a struct: structPerson structPosition anothe example is the enum, although I may not prefix it with "enum", but maybe with "enm": enmFruits enmSex again my reason is so that in IntelliSense, I see all my enums in one place. Because, .NET has so many built in data structures, I think this helps me do less searching. Please I used .NET in this example, but I welcome language agnostic answers.

• Are there any examples of a temporal field/object updater?

  - by Bryan Agee

  The system in question has numerous examples of temporal objects and fields--ones which are a certain variable at a certain point in time. An example of this would be someone's rate of pay--there are different answers depending on when you ask and what the constraints might be; eg, can there ever be more than one of a certain temporal object concurrently, etc. Ideally, there would be an object that handles those constraints when a new state/stateful object is introduced; when a new value is set, it would prevent creating negative ranges and overlaps. Martin Fowler has written some great material on this (such as this description of Temporal Objects) , but what I've found of it tends to be entirely theoretic, with no concrete implementations. PHP is the target language, but examples in any language would be most helpful.

• Finding Telecommuting Opportunities as a Recent College Graduate

  - by stanigator

  Reading the answers to hiring practices of remote vs. local employees and freelance programming sites, I would like to add this question to the mix. I am a recent college graduate from an electrical engineering background with 2 years worth of work terms in programming (C, C++, VBA, Matlab, etc.) while I was still in school. While I am interested in learning other software tools (such as Python, Ruby on Rails, Javascript, etc.), I want to use the tools I have now in a telecommuting role while I grow my toolset. Despite having 2 years of work experience (and I've lost track of when I have started programming), my status as a recent college graduate may be an obstacle of my credibility to compete for telecommuting (or in fact any) programming opportunities. I don't know how I can go about finding telecommute programming opportunities for someone with my situation. Overall, many of previous places I've worked at liked my work. What are your suggestions? Thanks in advance!

• Authentication for users on a Single Page App?

  - by John H

  I have developed a single page app prototype that is using Backbone on the front end and going to consume from a thin RESTful API on the server for it's data. Coming from heavy server side application development (php and python), I have really enjoyed the new different design approach with a thick client side MVC but am confused on how best to restrict the app to authenticated users who log in. I prefer to have the app itself behind a login and would also like to implement other types of logins eventually (openid, fb connect, etc) in addition to the site's native login. I am unclear how this is done and have been searching - but unsuccessful in finding information that made it clear to me. In the big picture, what is the current best practice for registering users and requiring them to login to use your single page app? Once a user is logged in, how are the api requests authenticated? Can I store a session but how do I detect for this session in the API calls? Any answers to this would be much appreciated!

• What are the most important programming skills you need to improve as a team Leader or project manager?

  - by Aba Dov

  I decided to ask this question after I read the valuable answers to the great question What is the single most effective thing you did to improve your programming skills? and after attending Ad Burns "Secrets of a rock star programmer". It made me think about me and what programming skills I try to improve. I came to realize that there should be a difference in the programming skills you try to improve as developer and the programming skills you should improve as a team leader or project manager. My question is: What are the most important programming skills you need to improve as a team Leader or project manager? What would you recommend to others that want to improve?

• Mock Objects for Testing - Test Automation Engineer Perspective

  - by user9009

  Hello How often QA engineers are responsible for developing Mock Objects for Unit Testing. So dealing with Mock Objects is just developer job ?. The reason i ask is i'm interested in QA as my career and am learning tools like JUnit , TestNG and couple of frameworks. I just want to know until what level of unit testing is done by developer and from what point QA engineer takes over testing for better test coverage ? Thanks Edit : Based on the answers below am providing more details about what QA i was referring to . I'm interested in more of Test Automation rather than simple QA involved in record and play of script. So Test Automation engineers are responsible for developing frameworks ? or do they have a team of developers dedicated in Framework development ? Yes i was asking about usage of Mock Objects for testing from Test Automation engineer perspective.

• Torrent clients suddenly stop downloading

  - by Vasilis Baltikas

  A few days ago I noticed, that Transmission in my Ubuntu 10.04 machine suddenly couldn't download anything anymore. To overcome this I have uninstalled and reinstalled Transmission and tried downloading with other clients (Deluge, Vuze) well seeded torrents (ubuntu iso images for example) without success. On the same computer I have also installed Ubuntu 10.10 and Windows 7, which I rarely use. What makes the problem I encounter weirder, is the fact that downloading via torrents works fine in my Ubuntu 10.10 and Windows partitions but not in Lucid Lynx. Browsing the web for similar problems didn't give me answers. Any help would greatly appreciated.

• Why use string.Empty over "" when assigning to a string object

  - by dreza

  I've been running StyleCop over my code and one of the recommendations SA1122 is to use string.Empty rather than "" when assigning an empty string to a value. My question is why is this considered best practice. Or, is this considered best practice? I assume there is no compiler difference between the two statements so I can only think that it's a readability thing? UPDATE: Thanks for the answers but it's been kindly pointed out this question has been asked many times already on SO, which in hind-sight I should have considered and searched first before asking here. Some of these especially forward links makes for interesting reading. SO question and answer Jon Skeet answer to question

• What would you change about C# if you could?

  - by Casebash

  Assume that your objectives are the same as for C#. I don't want an answer like "I'd write Python instead". I'm only interested in changes in the language itself - not in the standard library. Perhaps this would be interesting to discuss, but as it is shared between many languages it would be better to discuss this in another question instead. Please post a single idea per answer; if you want to post several ideas, post several separate answers. Thanks!

• Efficiently representing a dynamic transform hierarchy

  - by Mattia

  I'm looking for a way to represent a dynamic transform hierarchy (i.e. one where nodes can be inserted and removed arbitrarily) that's a bit more efficient than using a standard tree of pointers . I saw the answers to this question ( Efficient structure for representing a transform hierarchy. ), but as far as I can determine the tree-as-array approach only works for static hierarchies or dynamic ones where nodes have a fixed number of children (both deal-breakers for me). I'm probably wrong about that but could anyone point out how? If I'm not wrong are there other alternatives that work for dynamic hierarchies?

• Proprietary AMD driver freezes my Ideapad

  - by mote

  I got this problem that I can't figure out what to do about. On Ideapad s205 with Ubuntu 12.04* (64), if I install Catalyst Centre 12.1 or newer it Freeze (lock's up), 1-3 times a day. It doesn't suffer freezing when using Radeon driver, but Radeon driver are considerably slower and flickers, so I would really prefer the proprietary driver (with no freezing). I reported the bug to launchpad but it doesn't get attention. -Also tried Ubuntu forums. Reported bug to AMD bug site "http://ati.cchtml.com/", but I don't think anybody reads it. Wrote AMD support several times, but get silly answers like "reinstall Windows". -Asked them to send the bug to Linux driver developers, but never heard a thing (more than once). The same nothing happens when writing to the feedback link from AMD driver download site. I'm so frustrated here, any advice would help. Thanks (*The same on Ubuntu 11.10)
