• Can I develop games for mobile platforms in C++?

  - by James Bern

  I have a good grasp in C++ and C and have also experience developing AAA game using C++. Now, I'm shamelessly thinking to dive into mobile game development either in iOS or Android. Unfortunately, I don't know objective-C and java and neither have courage to learn it. So, As above mentioned reason, Is there any possibility to do mobile development in C++ without using any single statement of JAVA and Objective-C ?

• System Settings and Software Center does not pull up after fresh install 11.10 amd64

  - by hydroparadise

  I've had a few install rounds with ubuntu ever since 8.04 and has worked flawlessly every time. However, for some reason, when I try to click either System Settings or Software Center, the icon pulses as if it were working to come up but never does. The same goes for System Settings. I would expect that a password dialog would appear, but nothing shows. Is there bug with 11.10 that didn't exist with 11.04?

• What are the tradeoffs involved in referencing Context in a library?

  - by C. Ross

  Context is one of the core classes of Android, and many functions it contains are useful in Android library projects, particularly accessing configuration. What are the trade offs involved in accessing the Context in a library, either by injection or by subclassing Application in the library, and subclassing that in the application. Does this make the application brittle or introduce inappropriate coupling?

• How can I use my keyboard as a mouse?

  - by Michael Durrant

  I'm using my keyboard more and more these days for basic command line stuff, vim editing, alt-tab window switching and the like. Q) How can I use my number pad keys to move the cursor around on the screen without using the mouse? I looked to try and install btnx as mentioned by others but it doesn't seem to exist anymore as an available package I also tried shift-numlock as mentioned by another but that didn't work either (just turns numlock on/off).

• 24 Hours of PASS next week, pre-con preview style

  - by drsql

  I will be doing my Characteristics of a Great Relational Database , which is a session that I haven’t done since last PASS. When I was asked about doing this Summit Preview version of 24 hours of PASS, I decided that I would do this session, largely because it is kind of light and fun, but also because it is either going to be the basis of the end section of my pre-con at the summit or it is going to be the section of the pre-con we don’t get to because we are so involved in working out designs that...(read more)

• Disable “Alt+`”

  - by Albert Francis Lavietta

  How do I disable the keyboard combination of ALT+`. This is NOT the HUD nor in the Ubuntu System Settings. It is NOT in compiz configuration either. (I am NOT trying to disable the HUD's use of the Alt key*) When you press ALT+` on a default unity ubuntu 12.04 install it behaves the same as ALT + TAB. I would like to disable this, because my Windows 7 VM Uses ALT+` to switch languages such as korean or chinese.

• Is there any copyleft (GPL-like) license with both the Affero and Lesser modifications?

  - by Ben Voigt

  Looking for a license that covers public network service, like AGPLv3, but like LGPL isn't infectious. Basically I wrote some useful helper functions I want to allow to be used in any work, including closed-source software, but I want to require improvements to MY CODE to be released back to me and the general public. Can you recommend a suitable license? It should also include some of the other AGPL-permitted restrictions (attribution, indemnity), either in the license text or as permitted variations.

• Good, simple reasons for having multiple environments

  - by smp7d

  Throughout my career I had worked at companies that had a collection of different environments for different purposes. We always had more or less our desktop environment, a test environment, a QA environment, a staging environment and a production environment. This went for both servers/applications and any data sources we were using. When I started at my current company I found that 90% of the apps were either developed on a desktop environment against production data sources or developed directly on the production server depending on the platform. I wasn't fazed because I was hired in part to make changes to improve the way the development team functioned, which was clear from my interview process. We slowly started to turn the philosophy and pretty soon, most of the apps could be run in either a desktop, test or production environment. Not too long after that staging came around as well. Now most of our developers see the benefit of this methodology and defend it vigilantly. However, we have a number of legacy apps that never got migrated. We also have a number of legacy programmers who think of this as a waste of time. Unfortunately, we got lip service but never full buy-in from management. We got what we thought was a commitment to invest substantially in this about a year ago, but nothing materialized despite the considerable planning that we put into it. Now we are finding that we need more and more environments. We need help from the server/network administration teams for setup and we need participation from the business stakeholders to support the release cycle. We are at a place now where a project can function what I consider "normally" only if you have the right people on the project and the time to set up the proper environments. I'd love to present a complete argument, but management really has no time and interest in hearing me out until there is a critical issue. I can't really articulate the benefits simply as it always just seemed second nature to me. I was wondering if there are any good, simple, irrefutable reasons for the separation of environments that would get managers with no development experience to get behind this idea. Are there any good resources/literature on the topic?

• DirectX 10 Instancing Problem (objects cannot be seen)

  - by Riffraff

  Right now I'm trying to implement an area that is filled with vegetation. I have tried mesh version and right now I'm trying to implement instancing version but I cannot manage to make it work. I can't see any object. I search for any problem of buffers with FAILED() and D3D10_CREATE_DEVICE_DEBUG but they didn't help me either. Right now I don't even know which part of my code to share to explain my problem.

• Which tool can tidy/indent HTML5?

  - by user2534

  I've already spent about 2 hours searching google and trying various tools but either they don't do indent tags per say or they aren't HTML5 compatible such as the famous HTML tidy which was last updated 3 years ago… N.B. I don't want to apply this to the source of a page (like PHP or JS would do) but to the code in the editor so that a clear hierarchy appears between tags. Ideally I'd like a Mac OS X tool but I'll take any online tool and in last resot a Wine compatible one. P.S. at the moment I use Coda from Panic

• iOS - Unit tests for KVO/delegate codes

  - by ZhangChn

  I am going to design a MVC pattern. It could be either designed as a delegate pattern, or a Key-Value-Observing(KVO), to notify the controller about changing models. The project requires certain quality control procedures to conform to those verification documents. My questions: Does delegate pattern fit better for unit testing than KVO? If KVO fits better, would you please suggest some sample codes?

• How to reduce MDX code redundancy in SQL Server Analysis Services (SSAS)

  To query an Analysis Services cube, MDX is used as the query language. In most business settings, one would find a set of queries that are common across a number of user query requirements. To cater to this, even with a modest size IT team, there is a good chance that the same queries are developed redundantly either within a SSAS MDX script or repetitively in an ad-hoc manner in client applications. In this tip we would look at how to reuse queries without redeveloping them over and over.

• Why can't 12.04 installer see one of my hard drives

  - by imparatore

  I'm trying to install Ubuntu 12.04 32-bit from a USB pen drive. I have two drives, a WD Caviar Black and a Samsung SPC250. At the "installation type" stage, it only sees my Samsung and the USB pen drive, not the WD. I checked the drive with gparted and everything seems fine. I tried the alternate installer but that doesn't work either I tried changing from IDE to AHCI in the BIOS and back What can I do now?

• Why are there so many string classes in the face of std::string?

  - by fish

  It seems to me that many bigger C++ libraries end up creating their own string type. In the client code you either have to use the one from the library (QString, CString, fbstring etc., I'm sure anyone can name a few) or keep converting between the standard type and the one the library uses (which most of the time involves at least one copy). So, is there a particular misfeature or something wrong about std::string (just like auto_ptr semantics were bad)? Has it changed in C++11?

• Rolling Back the Clock: Shell only Programs

  <b>Systhread:</b> "System Administrators who remember the day when they did not have a graphics display rarely think about wanting to time travel for the pure joy of using a terminal. It is possible, however, to virtually do so by using either all or mostly text only utilities and perhaps a retro looking X windows desktop. In this text a look at a small experiment to see how well that went in one particular instance."

• Large uploaded file won't display in Ubuntu One but is included in file usage

  - by user1488963

  On Ubuntu 10.04, I uploaded a single 711 MB. My total file usage in Ubuntu One went up to 877MB, which is about right, but the file doesn't show in Ubuntu One so I can't download or delete it. Either the file is there and I can't see it for some reason. Or the file is not there and the total file usage figure is wrong. Does anyone know what has happened? I have a free account but am well below my 5GB limit.

• Can I run `apt-get purge --auto-remove`?

  - by user981178

  Is apt-get purge --auto-remove packagename a valid command? Or, does it have to be apt-get remove --purge --auto-remove packagename? The Ubuntu manpage for apt-get (http://manpages.ubuntu.com/manpages/precise/man8/apt-get.8.html) only mentions using the --auto-remove option "If the command is either install or remove...", so I was wondering if it could also be used with the purge command, since that is just a shortcut for the remove command with the --purge option. Thank you.

• Alternative for Sharepoint 2010 Discussion Boards

  If you have tried Sharepoint discussion boards, you already know that you cannot offer a PROPER forum experience with it. It's still very primitive and it will take considerable time and effort you to extend and customize.Fortunately I found that there are some third party solutions, and Lightning Storm Forum is a very nice alternative. I'ts not free but not that expensive either.You can try it for free and can have a proper forum running in your website withing less than an hour :)http://lightningtools.com/products/storm-forums/

• Generate md5 and other checksums from properties menu (added "Digests" tab)

  - by Chuck

  I am trying to restore a function that I had on my last box. It added a tab in the properties menu of any file called "Digests". From there I could choose any/all of the hash formats, click hash and it would generate said checksums right there. What I am trying to find out is either the name of the package or acquire the location of it's installation. I have started a thread on UbuntuForums pertaining to this already
