• Keyboard Shortcuts no longer working on Ubuntu 12.04 with GNOME 3.4.1 [closed]

  - by Peter

  Possible Duplicate: What is the keyboard shortcut to minimise a window to launcher in unity? I upgraded from Ubuntu 11.10 (with Gnome 3.2 I think), to Ubuntu 12.04 with Gnome 3.4.1, and my custom shortcuts have stopped working. Opening up the All Settings - Keyboard - Shortcuts, I can see that my shortcuts are still there. All of the shortcuts that I didn't change are working, and my shortcuts in the custom section are working (eg Ctrl+Alt+G to open gedit), its just that the shortcuts I had customised before the upgrade no longer work. Under Launchers, I had changed "Launch Terminal" to Ctrl+Alt+T, and under Navigation I had changed move to workspace above/below to Shift+Ctrl+Up/Down. Investigating further, it looks like the default shortcuts for these actions work (Ctrl+Alt+Up/ Down moves me up and down workpaces), so I'm guessing that there is some discrepancy between what I am seeing on the Keyboard Settings and what my computer is reading from. Any help would be appreciated.

• My boss decided to add a "person to blame" field to every bug report. How can I convince him that it's a bad idea?

  - by MK_Dev

  In one of the latest "WTF" moves, my boss decided that adding a "Person To Blame" field to our bug tracking template will increase accountability (although we already have a way of tying bugs to features/stories). My arguments that this will decrease morale, increase finger-pointing and would not account for missing/misunderstood features reported as bug have gone unheard. What are some other strong arguments against this practice that I can use? Is there any writing on this topic that I can share with the team and the boss? I find this sort of culture unacceptable to work in but want to try and change it before jumping ship. Any input is appreciated.

• Is this a pattern? Proxy/delegation of interface to existing concrete implementation

  - by Ian Newson

  I occasionally write code like this when I want to replace small parts of an existing implementation: public interface IFoo { void Bar(); } public class Foo : IFoo { public void Bar() { } } public class ProxyFoo : IFoo { private IFoo _Implementation; public ProxyFoo(IFoo implementation) { this._Implementation = implementation; } #region IFoo Members public void Bar() { this._Implementation.Bar(); } #endregion } This is a much smaller example than the real life cases in which I've used this pattern, but if implementing an existing interface or abstract class would require lots of code, most of which is already written, but I need to change a small part of the behaviour, then I will use this pattern. Is this a pattern or an anti pattern? If so, does it have a name and are there any well known pros and cons to this approach? Is there a better way to achieve the same result? Rewriting the interfaces and/or the concrete implementation is not normally an option as it will be provided by a third party library.

• How do I best remove an entity from my game loop when it is dead?

  - by Iain

  Ok so I have a big list of all my entities which I loop through and update. In AS3 I can store this as an Array (dynamic length, untyped), a Vector (typed) or a linked list (not native). At the moment I'm using Array but I plan to change to Vector or linked list if it is faster. Anyway, my question, when an Entity is destroyed, how should I remove it from the list? I could null its position, splice it out or just set a flag on it to say "skip over me, I'm dead." I'm pooling my entities, so an Entity that is dead is quite likely to be alive again at some point. For each type of collection what is my best strategy, and which combination of collection type and removal method will work best?

• VS2010 changes your ASP.NET Version on setup projects to 4 - regardless

  - by blomqvist

  When converting your projects to VS2010 you get the question to migrate them to .net4. But even if you do not do that VS set the ASP.NET version to 4 for setup projects. And then when you try to install your application on a machine that does not have .NET 4 installed you will get the error message: “Could not open key: Software\Microsoft\ASP.NET\4.0.30128.0. Verify that you have sufficient access to that key, or contact your support personnel” What you need to do is to change the ASP.NET version back to 2.0 if that is what you want to use. You do that in the properties of the setup project.

• My gnome terminal keep opening new window

  - by evan

  I actually want to change the default window position of gnome-terminal in my Ubuntu 12.04 system. After some search, I found some one else use the command gnome-terminal --geometry=120x80+50+50 to set the default position. And I actually don't know where to paste the command, so I pasted it to 'custome command' field of terminal's profile. Now when I open one terminal, it just keep opening new ones and I have no way to stop it other than ctrl+C. I even removed .gconf/gnome-termial/ folder and it didn't worked. Can someone help me?

• Running Mixed Physical and Virtual Exalogic Elastic Cloud Software Versions in an Exalogic Rack is now Supported

  - by csoto

  Although it was not supported on older versions, now as of EECS 2.0.6, an Exalogic rack can be configured in a mixed-mode: half virtual and half physical Linux: Flexibility to have physical and virtual environments on same rack. For example, production on physical and test/dev on virtual. Exalogic Control manages the virtual compute nodes on the rack. Physical compute nodes are managed manually (including PKeys). Option to change full physical to hybrid and hybrid to full virtual rack. User has an option to choose either the top or bottom nodes for physical or virtual deployment. For further information about how the compute nodes can be split up on the rack (into bottom or top half) to run either Oracle Virtual Server (OVS "hypervisor") or Oracle Linux, please take a look at MOS Note 1536945.1. Note: Solaris is not yet supported in the mixed configuration.

• What is the concept behind writing a cancel operation in c++?

  - by ToMan

  I'm attempting to write a cancel operation for a software download application. This application will first transfer the software to the device and then install the software on it. (These are givens I'm not allowed to change). What should the cancel operation do? When a user presses 'cancel', the application should stop transferring/installing the software immediately. Question: Since I've never written a "cancel" function, I'm wondering what are the types of things to consider when writing the code, and what are the common bugs I should expect and how to deal with them? Couldn't find anything in google so if you have some links that would be good reads I'd really appreciate it since I'm not looking for answers I'm just looking for guidelines/macro/concept help

• Compiz using 40% CPU on Ubuntu 13.10

  - by Olli

  After upgrading to 13.10, compiz process has started taking up to 40% of CPU resources. In addition, Unity is sluggish just like in this recent question Compiz at 30% of CPU on Thinkpad T420. My PC is HP Compaq NX6310 and Compiz version is 0.9.10.2. First I had error message during boot, but did find solution for that (Bug #1014289) by updating the kernel to newer 3.11.4, it did not change the CPU usage. For the CPU problem I tried solution for Bug #1221837 by adding the line MESA_GL_VERSION_OVERRIDE=1.4 in the file /etc/environment - that did not help me, so my problem seems not to be the same bug. Any suggestions on how to resolve this issue?

• Is it OK to have all these Window Managers?

  - by JMCF125

  Hello again, This is not actually one, but several related questions. I have installed Xfce, KDE, Gnome Fallback and DWM (and obviously I have Unity). How can I change the login screen? It is currently always Kubuntu's (also on shutdown), though strangely kubuntu-desktop wasn't the first nor last to be installed. Why? Where is/are the file(s) with which Window Manager to start? Can I start without X and then start it from the tty? Is all this OK? Is it safe? I hope you can help me with this, since whenever I login to an envirnment other than KDE, I have to login again (except on DWM).

• What is the SEO-recommended method for using underscores and dashes in URLs that contain geographic locations?

  - by ElHaix

  In reading through this article: In Subfolder & File Names, Use Dashes, Not Underscores Good: Good: http://www.domain.com/sub-folder/file-name.htm Bad: http://www.domain.com/sub_folder/file_name.htm In my URL's, I may have one or two city names, ending with the province/state: Burnaby_New_Westminister-BC/[some search term]. My URL rules currently are defined such that everything after the dash is the prov/state. Some geographic locations already contain dashes: Notre-Dame-de-Grâce (in QC), which I would convert to ~/Notre_Dame_de_Grace-QC/ I thought of placing the prov/state after another "/", however in some cases the province/state name may not exist, thus ~/Notre_Dame_de_Grace/, so the first term after the domain name contains the geo location {city, city_name-state}. I am now revisiting this, and wondering if this rule set should change, and if so, what is the recommended way of implementing this? -- UPDATE -- After reviewing this video, I see that I should be using the dashes, rather than underscores. However since I still want to have my geo locations in the first URL section, is there anything wrong with using a double-dash separator - ie: /city-name--state/ ?

• Trying to boot from USB on Asus q200e-bhi3t45 just brings me to grub menu

  - by Krash Kharma

  It's been a struggle every time I've tried to change my OS on this machine. I honestly don't even know how it works whenever it does. I've somehow managed to get Windows 7, Windows 8, Mint 14, Ubuntu 12.04, and 12.10 to work at random times but it's always after struggling with it and googling for random chance fixes and suddenly something clicks and it loads from usb, but 99% of the time, every time I try to boot from USB to install a distro (in this case, I'm trying to get ubuntu-12.04.2-desktop-amd64.iso to work) my pc just comes up with a grub menu ("Minimal bash-like blahblahblah - grub ") I don't know why it works when it works. Right now I've tried everything from with/without Fast Boot in BIOS, with/without CSM, with/without secure boot, to changing BOOTx64.EFI to bootx64.efi to downloading a new bootx64.efi to copying it to every folder on the usb.... It makes no sense to me. Sorry if this has been asked before but I can't find anything

• Are there any reasons to use Bazaar over Hg or Git?

  - by NeuronQ

  The world of DVCSs seems split between Git and Mercurial nowadays, but lots of projects and places (like my new employer) use Bazaar. And it's not a thing of inertia where people just use something because "that's how it's always been done", these guys are agile and sometimes seem to embrace change just for the fun of having more things to fix. Yet no one gave me any convincing arguments for using Bzr over Hg or Git. I can get seeing Git as "too complicated" but you can't use this king of judgement between Hg and Bzr. So then, what are the features of Bazaar that would justify its use over Mercurial (or Git) in any given situation?

• Startup value for Win7

  - by Mike

  Problem at a glance: For Win 7, Ubuntu One changes the startup value to enabled whenever I run it More Details: If I change the startup value in: Control Panel System and Security Administrative Tools System Configuration Startup to disabled for Ubuntu One (since I don't want it to start when I log on), it succesfully stops Ubuntu One from starting at logon However, if I start the Ubuntu One manually, it changes the above startup value to enabled. Is there a way to prevent Ubuntu One from changing its startup value? I want it to stay disabled. I haven't found anything relevant in Ubuntu One's settings dialog.

• JS framework with conditionally loaded fragments

  - by kjs3

  I'm doing a single-page, responsive, mobile first design. I found this article about conditionally loaded fragments but am wondering what the different js frameworks have build-in to handle this? I'm imagining the mobile version with a list view fragment that transitions to a show view fragment. A larger portal could just show both fragments and change the show fragment when items in the list are clicked. I'd love thoughts on what is available from the various frameworks, not an argument. Ember?, Angular?, etc. Maybe I'm missing it, but I'm not seeing the responsive fragments issue brought up in the various demos I've found so far.

• Is there an effective way to test XSL transforms/BizTalk maps?

  - by nlawalker

  Creating repeatable tests for BizTalk maps is frustrating. I can't find a way to handle testing them like I'd do unit testing, because I can't find ways to break them into logical chunks. They tend to be one big monolithic unit, and any change has the potential to ripple through the map and break a lot of unit tests. Even if I could break it up, creating XML test inputs is painful and error prone. Is there any effective way of testing these? I'd settle for recommendations for testing XSL transforms in general, but I specifically mention BizTalk maps primarily for the reason that when using the mapper, there really isn't any way to break your XSLT into templates (which I'd imagine you could use to break up your logic into testable chunks, but I've honestly never gotten that far with XSLT).

• Randomly spawning bitmaps on cnvas

  - by Toystoj

  I need some ideas in order to finish algorithm. I'm randomly placing objects (bitmaps) on canvas without overlapping. Time needed to finish it is my problem. When I need to spawn for example 80% of canvas it takes to long. So i was thinking : I should make some change when the bitmaps take off 50 % of canvas. I want to tell algorithm that it should generate new locations (x,y) where it is free space. My question is : How to render new location (x,y) in place where is free space. In summary: Things I know : object location (x,y) 4 corners (x,y) of object object width, height canvas width, height Any suggestions?

• How to build completely modular web applications

  - by Webnet

  In the coming months we're going to begin a project where we take a system we've built for a client (v1) and rebuild it from scratch. Our goal with v2 is to make it modular, so that this specific client will have their own set of modules they use, then another client may use a different set of modules altogether. The trick here is that Company A might have a series of checkout and user modules that change how that system works. Company B might stick with the standard checkout procedure but customize how products are browsed. What are some good approaches to application architecture when you're building an application from scratch that you want to have a Core that's shared among all clients while still maintaining the flexability for anything to be modified specifically for a client? I've seen CodeIgniter's hooks and don't think that's a good solution as we could end up with 250 hooks and it's still not flexible enough. What are some other solutions? Ideally we won't need to draw a line in the sand.

• GUI app for Bandwidth Shaping (Internet Speed Limiter)

  - by Luis Alvarado

  This is a similar question as this one: Limit internet bandwidth but in this case I am looking for a GUI app. The other question was 2+ years ago so a GUI might be available that I could use to not only monitor but also change the maximum speed at which clients can download. A WebApp or a GUI app will help. It needs to work on 12.04 or newer. Just to give an idea, I am looking for something similar to NetLimiter that gives me the control to know: How much Download/Upload speed an IP/Mac has (Assuming this is a LAN) Limit the Download/Upload speed for an IP/Mac. Option to say I what time a speed can be limited or not. Can cap when a certain amount has been downloaded/uploaded (Like 250MB per day)

• Unable to boot from USB boot drive for AMD Athlon 64

  - by Nagarjun

  I am trying to install Ubuntu 13.04 ISO for AMD64 Athlon processor using USB drive (8GB). I did create a bootable USB using the USB installer from Win7 intel 32bit processor (followed steps from here: http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows). This USB is unable to boot on my AMD64 bit processor. The bios is able to detect the USB and once I change the boot order to USB and save exit from bios, I get a message saying "DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS CONTINUE" and unable to proceed further. However earlier to this I have successfully installed Ubuntu 13.04 on to my laptop which has Intel 32 bit core i5 processor with the same procedure but my desktop which has AMD64 is failing. I also tried to create the USB installer on my desktop which has the AMD64 bit processor and tried booting which also resulted in the same error. (My desktop currently has Win XP) Please help as I have run out of options. thanks, Nagarjun
