• How to run CLI commands from the launcher?

  - by user50849

  I press ALT+F2 key on my keyboard, and get the launcher HUD up. From there I enter a command as I would in a shell, specifically vlc ~/Music/* -Z. If done from a shell, vlc starts and begins to play music. However, when done from the launcher, VLC replies: File reading failed: VLC could not open the file "/home/[username]/Music/*". (No such file or directory) user Your input can't be opened: VLC is unable to open the MRL 'file:///home/[username]/Music/%2A'. Check the log for details. I can't quite figure out what the difference is.

• Where is the best place to start projects and attract developers?

  - by user49557

  I want to develop software for Linux or cross-platform. I want to work with other open-source and non-profit developers. I want a place where Ubuntu or other developers come to start open-source or commercial projects, and we can join the projects or start our own projects. I know there are social coding sites, but where can I start the project, and invite people or let people join? Then we can submit software to sourceforge.net. I know we can start projects at sourceforge.net, but is there anything more dedicated for Ubuntu developers, especially for Ubuntu and for the Ubuntu Software Center? Would you recommend Launchpad, sourceforge.net, github, gitorous or others?

• GPL exception that allows linking to free licenses only?

  - by fNek

  There is the GPL license and the linking exception which allows closed-source programs to use the program as a library. There is also the slightly more restrictive LGPL (more restrictive than GPL with exception since it requires that the user can change the library in the resulting project, etc.). And there is the Cygwin exception that allows linking to open source programs. I see clear advantages: Open-Source programs may use the library. People may use these programs for closed-source programs, but then they lose the permission to use the (GPL) library. However, there are two things I don't like about the Cygwin exception: - Its legal status is disputed - I keep hearing that it is basically worthless - It requires certification by the OSI, I would rather have certification by FSF Is there an exception to the GNU General Public License that meets my requirements?

• Software Center crashes and terminal errors

  - by user97521

  *note*I'm a new user to Ask Ubuntu and I've only recently switched to Ubuntu 12.04. When I try to open the software center (Ubuntu 12.04 32-bit) it will flash open, load for maybe 1-2 seconds, and then close. When i try using: sudo apt-get purge software center sudo apt-get install sudo apt-get update sudo apt-get upgrade I get this within the terminal: Reading package lists... Error! E: Problem parsing dependency Depends E: Error occurred while processing printer-driver-hpcups (NewVersion2) E: Problem with MergeList /var/lib/dpkg/status E: The package lists or status file could not be parsed or opened. *The problem fixed itself after I shut down my laptop for the night and turned it back on to check my e-mail this afternoon. If anyone could tell me how to fix this problem in the future please do, I would like to learn about these kind of things because i don't plan on putting windows on my laptop again :P *

• Which one is better to get started? [closed]

  - by vanangamudi

  Which one of the open-source game engine is better to get started? I read several threads over several forums and found that it is better to write own game engine specific to application. But I need to know the requirements of a game engine, other than Graphics, Physics and AI... Many people suggested Unity, But I need open-source version so that I can have a look at implementation... so I google rigorously and found some unknown game engines(at least to me) Unvanquished Cube Spring Pyrogenesis Torque3D CrystalSpace Panda3D Delta3D Irrichlt OpenArena AlienArena (please list others if I missed anything....) FYI: my present focus is on FPS/TPS. Can you tell me which one is better at performance if possible? Torque3D claims to be the best opensource engine - is that true, and if so to what extent?

• How can I redirect the contents of a file to the pastebinit command? [duplicate]

  - by Tim

  This question already has an answer here: How to submit a file to paste.ubuntu.com without graphical interface? 2 answers Whenever I was to store something to show someone here, I run command-with-output | pastebinit. That returns the link to the paste online. For example: echo timtjtim | pastebinit gave me the link paste.ubuntu.com/8010000 Which I can share. How can I do this with a file - for example a log file. Surely I don't have to open - > copy all - > open paste.ubuntu.com -> paste it?

• How to access parent window in dialog

  - by Bruce

  I am using Quickly and created the main window and a dialog. In the main window I am setting access to database (u1db) in the finish_initializing method (self.db=...). After an action I open a dialog where I need access to the database. I thought that I can use self.get_parent() in the dialog to get instance of the main window and access the database, but return value of the get_parent() is None. My question is, how can I access the instance of the parent window in the dialog or perhaps where should I place the instance of the database wrapper? Shortened code: class GuitestWindow(Window): def finish_initializing(self, builder): ... self.db = u1db.open( db_path, create=True ) def on_addaccountbutton_clicked(self, widget): dialog = NewAccountDialog.NewAccountDialog() result = dialog.run() dialog.hide()

• Bad search result due to strange linked domains

  - by VDesign

  I have a website which is not scoring good in Google's search results. I use Majestic SEO and Open Site Explorer in order to have a view about my link profile. I now see different backlink domains, some of them already removed, that contains sexual content or other non relative content linking to my domain. How much influence does these strange linked domains have on my search result? Even if some of them are already removed for a couple of months. I have already disavow open sexual domains using the tool that Google provides.

• Database Context and Singleton injection with IoC

  - by zaitsman

  All of the below relates to a ASP.NET c# app. I have a Singleton Settings MemoryCache that reads values from database on first access and caches these, then invalidates them using SQL Service Broker message and re-reads as required. For the purposes of standard controllers, i create my Db Context in a request scope. However, this obviously means that i can't use the same context in the Settings Cache class, since that is a singleton and we have a scope collision. At the moment, i ended up with two db contexts - the Controllers get it via IoC container, whereas a Singleton just creates it's own. However, i am not satisfied with this approach (mostly due to the way i feel about two contexts, the cache doesn't set anything on the db hence concurrency is not an issue as much). What is a better way to do it?

• Dropbox and IIS

  - by DigitalAce7

  I'm running into the problem of using Dropbox and IIS. I am using the Dropbox Folder Sync plugin to sync a folder outside the Dropbox folder. They are synced into my inetpub\root\downloads\ directory. The problem is not that it doesn't sync. The problem is that the files that get synced have no permissions attached to them. I can't open any of them on IIS. Initially the downloads were to be only PDFs but they don't open so I tried an .ASPX file and it fails to load as well. Is there any way around this or another program I can use to sync files but allow them to be opened on an IIS server. Thanks for any help!

• Am I making the right decision to take Information technology/system as my course in college?

  - by 123rainfan

  I am a student who just ended my high school last year. I will be entering college any time between march to August. And.. I am thinking of studying Information technology/System as my course in college. The problem is, I am unsure if this is the right path for me. I don't know if this is what I really want for my future later on! Yes, I do love learning more about computers (prefer software to hardware). But what if I don't find them interesting later on when studying? I'm worried about that as I don't wanna regret later on. To add to that, my knowledge of programming and other software development is actually quite low. Can someone advise me on what should I do? Or tell me more about Information technology (what will I study later on in college and the career path)?

• f12 and ctrl + f5 not working correctly [migrated]

  - by ComatoseDuck

  When I came back to my work computer after being away for a week I found out when I try to clear the cache and refresh the page via ctrl + f5 (or just f5) I get the prompt "Type the Internet address of a document, and Internet Explorer will open it for you" with a drop down list in IE. When I try f5 in Chrome and FF it opens the "Open file" dialog box. When I try to f12 for Dev tools in IE, Chrome & FF it opens up the print dialog box. Why is this happening and what can I do to revert it back to the way it was?

• Will taking a job that's web and database related limit my software development opportunities later on?

  - by someone

  I love programming, particularly OOP. My school experience was mostly in Java/OOP, and I had a job for a limited time in Java, Python, and other OOP kind of languages. However, a move necessitated a change in jobs, and what I've ended up with now is a web-development and database intensive job. I may possibly hold this job for several years. My question is, will this limit my choices later on? Will I be able to find another Java / software-development kind of job, or will I be rejected because my experience will be mostly in a different area?

• Most regrettable design or programming decision you made? [closed]

  - by VNarasimhaM

  I would like to hear what kind of design decisions you took and how did they backfire. Because of a bad design decision, I ended up having to support that bad decision forever (I also had a part in it). This made me realize that one single design mistake can haunt you forever. I want to learn from the more experienced people what kind of blunders have they experienced and what did they learn from them. I'm sure this will be a lot of help to other programmers by helping them to not repeat those decisions. Thanks for sharing your experience.
