• Software Center empty "No usefulness from server" "no username in config file"

  - by Theron G. Burrough

  I upgraded to 12.04 LTS and ran Software Center while a few things were running, and crashed. (2 GB RAM on a Netbook.) On reboot, Ubuntu One interface would not find any programs, neither installed (to run) nor available for download. So I launched Software Center, which opens, but does nothing. I click "Close" button and get a "Force Quit?" box. So I quit. Did research, learned to run Software Center from Terminal: 2012-04-29 23:14:36,978 - softwarecenter.backend.reviews - WARNING - Could not get usefulness from server, no username in config file Then tried the below without success: Reinstallation of software center: sudo apt-get install --reinstall software-center Didn't work. Found this in a post: remove the config file for software-center then log out and back in sudo rm -rf ~/.config/software-center Didn't work. Reinstalled Software Center with Synaptic Package Manager. Still no dice! And I am a Linux newbie, so I don't know where the Dickens that config file is. Help appreciated.

• A project idea I've got...

  - by Mr Teeth

  Hi, Next year I will be doing a final year project at Uni. I've already thought of one and was wondering what you guys think of it. I want to create a University Information Search for prospective students who are trying to look for an affordable University to attend. It will depend on the student's family income and the grades they get. They enter in those two parameters (and some more) and it comes up with a list of suitable Unis based on their criteria. This is not about the price of tution fee. It's mostly to do with the cost of living. Stuff like: Rent (if living in a private flat). Student Accomadation. Cost of traveling to your home and back (for holidays). ...and some other stuff stuff I haven't thought about yet. It'll mostly be GUI driven with some textual information. I'm also thinking of using it as a website interface. What do you guys think? Can I program something like this Java? If there's any holes you see in my idea please tell me.

• How to structure my GUI agnostic project?

  - by Nezreli

  I have a project which loads from database a XML file which defines a form for some user. XML is transformed into a collection of objects whose classes derive from single parent. Something like Control - EditControl - TextBox Control - ContainterControl - Panel Those classes are responsible for creation of GUI controls for three different enviroments: WinForms, DevExpress XtraReports and WebForms. All three frameworks share mostly the same control tree and have a common single parent (Windows.Forms.Control, XrControl and WebControl). So, how to do it? Solution a) Control class has abstract methods Control CreateWinControl(); XrControl CreateXtraControl(); WebControl CreateWebControl(); This could work but the project has to reference all three frameworks and the classes are going to be fat with methods which would support all three implementations. Solution b) Each framework implementation is done in separate projects and have the exact class tree like the Core project. All three implementations are connected using a interface to the Core class. This seems clean but I'm having a hard time wrapping my head around it. Does anyone have a simpler solution or a suggestion how should I approach this task?

• Ubuntu 13.04 under Parallels Desktop - Black Desktop after X Windows Update

  - by Bob Reckhow

  I have been running Ubuntu 13.04 successfully on a MacBook Pro in a virtual machine in Parallels Desktop 9. Today (2013-10-17) after applying today's Ubuntu update, which included updates to X Windows, my Ubuntu 13.04 virtual machine launches, the launcher comes up, but the screen background is solid black, rather than the shaded orange colour of the default desktop background (and my desktop icons are "hidden behind this blackness", as well). I can launch applications from the launcher, and there is a very brief white flash on the screen, and then it returns to black. It's as if there is a "black blanket" covering the entire screen, so there is no way to interact with any application windows using the keyboard or mouse. The icons of the launcher are responsive to the mouse, so I can right-click and quit any application I have launched. But the rest of the screen is non-responsive to keyboard or mouse. This same behaviour happens with two different versions of Parallels Tools, so I am quite sure this is not a Parallels problem per se, although I could believe that it could be a paroblem with the interface between Parallels and this new updated X Windows code. Could anyone tell me what has happened, and how I might be able to fix this problem, so I can continue to use my Ubuntu 13.04 virtual machine? (I do have the option of reverting to a previous version of my virtual machine from before this update, but if possible I would prefer to keep my version of Ubuntu 13.04 up to date with the latest updates.) Thanks, Bob

• Automatic Generalization

  - by Nick Harrison

  I have been interested in functional programming since college. I played around a little with LISP back then, but I have not had an opportunity since then. Now that F# ships standard with VS 2010, I figured now is my chance. So, I was reading up on it a little over the weekend when I came across a very interesting topic. F# includes a concept called "Automatic Generalization". As I understand it, the compiler will look at your method and analyze how you are using parameters. It will automatically switch to a generic parameter if it is possible based on your usage. Wow! I am looking forward to playing with this. I have long been an advocate of using the most generic types possible especially when developing library classes. Use the highest level base class that you can get away with. Use an interface instead of a specific implementation. I don't advocate passing object around, but you get the idea. Tools like resharper, fxCop, and most static code analysis tools provide guidance to help you identify when a more generalized type is possible, but this is the first time I have heard about the compiler taking matters into its own hands. I like the sound of this. We'll see if it is a good idea or not. What are your thoughts? Am I missing the mark on what Automatic Generalization does in F#? How would this work in C#? Do you see any problems with this?

• How to document requirements for an API systematically?

  - by Heinrich

  I am currently working on a project, where I have to analyze the requirements of two given IT systems, that use cloud computing, for a Cloud API. In other words, I have to analyze what requirements these systems have for a Cloud API, such that they would be able to switch it, while being able to accomplish their current goals. Let me give you an example for some informal requirements of Project A: When starting virtual machines in the cloud through the API, it must be possible to specify the memory size, CPU type, operating system and a SSH key for the root user. It must be possible to monitor the inbound and outbound network traffic per hour per virtual machine. The API must support the assignment of public IPs to a virtual machine and the retrieval of the public IPs. ... In a later stage of the project I will analyze some Cloud Computing standards that standardize cloud APIs to find out where possible shortcomings in the current standards are. A finding could and will probably be, that a certain standard does not support monitoring resource usage and thus is not currently usable. I am currently trying to find a way to systematically write down and classify my requirements. I feel that the way I currently have them written down (like the three points above) is too informal. I have read in a couple of requirements enineering and software architecture books, but they all focus too much on details and implementation. I do really only care about the functionalities provided through the API/interface and I don't think UML diagrams etc. are the right choice for me. I think currently the requirements that I collected can be described as user stories, but is that already enough for a sophisticated requirements analysis? Probably I should go "one level deeper" ... Any advice/learning resources for me?

• Basic AppFabric Service Bus Programming Lifecycle

  - by kaleidoscope

  The tasks required to create an application that access the AppFabric Service Bus are as follows: Create a service namespace. This service namespace contains the resources used by the AppFabric Service Bus to support the application. Define the AppFabric Service Bus contract. A contract specifies the signature of the service, the data it exchanges, and other required inputs, behavior specifications, and object invariants. Implement the contract. To implement a service contract, create a class that implements the interface and specify custom runtime behaviors. Configure the service by specifying endpoint and other behavior information. Build and run the service. Build and run the client application. As with any iterative, service-oriented software development, it may not always be appropriate to follow the preceding steps sequentially, or even start from step 1. For example, if you want to build a client for a pre-existing service, you start at step 5. Or, if you are building a host service that others will use, you can skip step 6.

• Is it good idea to require to commit only working code?

  - by Astronavigator

  Sometimes I hear people saying something like "All committed code must be working". In some articles people even write descriptions how to create svn or git hooks that compile and test code before commit. In my company we usually create one branch for a feature, and one programmer usually works in this branch. I often (1 per 100, I think and as I think with good reason) do non-compilable commits. It seems to me that requirement of "always compilable/stable" commits conflicts with the idea of frequent commits. A programmer would rather make one commit in a week than test the whole project's stability/compilability ten times a day. For only compilable code I use tags and some selected branches (trunk etc). I see these reasons to commit not fully working or not compilable code: If I develop a new feature, it is hard to make it work writing a few lines of code. If I am editing a feature, it is again sometimes hard to keep code working every time. If I am changing some function's prototype or interface, I would also make hundreds of changes, not mechanical changes, but intellectual. Sometimes one of them could cause me to carry out hundreds of commits (but if I want all commits to be stable I should commit 1 time instead of 100). In all these cases to make stable commits I would make commits containing many-many-many changes and it will be very-very-very hard to find out "What happened in this commit?". Another aspect of this problem is that compiling code gives no guarantee of proper working. So is it good idea to require every commit to be stable/compilable? Does it depends on branching model or CVS? In your company, is it forbidden to make non compilable commits? Is it (and why) a bad idea to use only selected branches (including trunk) and tags for stable versions?

• Does the google crawler really guess URL patterns and index pages that were never linked against?

  - by Dominik

  I'm experiencing problems with indexed pages which were (probably) never linked to. Here's the setup: Data-Server: Application with RESTful interface which provides the data Website A: Provides the data of (1) at http://website-a.example.com/?id=RESOURCE_ID Website B: Provides the data of (1) at http://website-b.example.com/?id=OTHER_RESOURCE_ID So the whole, non-private data is stored on (1) and the websites (2) and (3) can fetch and display this data, which is a representation of the data with additional cross-linking between those. In fact, the URL /?id=1 of website-a points to the same resource as /?id=1 of website-b. However, the resource id:1 is useless at website-b. Unfortunately, the google index for website-b now contains several links of resources belonging to website-a and vice versa. I "heard" that the google crawler tries to determine the URL-pattern (which makes sense for deciding which page should go into the index and which not) and furthermore guesses other URLs by trying different values (like "I know that id 1 exists, let's try 2, 3, 4, ..."). Is there any evidence that the google crawler really behaves that way (which I doubt). My guess is that the google crawler submitted a HTML-Form and somehow got links to those unwanted resources. I found some similar posted questions about that, including "Google webmaster central: indexing and posting false pages" [link removed] however, none of those pages give an evidence.

• Advice on software infrastructure for a FLOSS bounty site

  - by michaeljt

  I am planning to set up a simple web site where people can offer bounties for work on FLOSS projects. Unfortunately I have no experience at web development (I am a C/C++ developer), so I was hoping someone might be able to suggest out-of-the-box packages (preferably Debian ones) I could use to build the site from. My idea of how the site would work is to keep things as simple as possible. The person proposing a bounty would enter a description with relevant links (particularly to a bugtracker entry with the project the work is to be done on, where the real discussion and work would take place) and information and place an initial contribution. Other people would be able to add (donate, not pledge) contributions, but any discussion would take place on the project's bugtracker. I am also planning to run a mailing list rather than a forum (at least initially), so that is not a requirement. Paypal seems to me to be the handiest payment mechanism. So overall what I need is probably a simple interface with Paypal integration and a simple database backend. I hope this is the right place for my question, if not I would be grateful for pointers to somewhere better. And of course, this is purely about the technical side, though I am more than happy to discuss other aspects of the project elsewhere.

• Data classes: getters and setters or different method design

  - by Frog

  I've been trying to design an interface for a data class I'm writing. This class stores styles for characters, for example whether the character is bold, italic or underlined. But also the font-size and the font-family. So it has different types of member variables. The easiest way to implement this would be to add getters and setters for every member variable, but this just feels wrong to me. It feels way more logical (and more OOP) to call style.format(BOLD, true) instead of style.setBold(true). So to use logical methods insteads of getters/setters. But I am facing two problems while implementing these methods: I would need a big switch statement with all member variables, since you can't access a variable by the contents of a string in C++. Moreover, you can't overload by return type, which means you can't write one getter like style.getFormatting(BOLD) (I know there are some tricks to do this, but these don't allow for parameters, which I would obviously need). However, if I would implement getters and setters, there are also issues. I would have to duplicate quite some code because styles can also have a parent styles, which means the getters have to look not only at the member variables of this style, but also at the variables of the parent styles. Because I wasn't able to figure out how to do this, I decided to ask a question a couple of weeks ago. See Object Oriented Programming: getters/setters or logical names. But in that question I didn't stress it would be just a data object and that I'm not making a text rendering engine, which was the reason one of the people that answered suggested I ask another question while making that clear (because his solution, the decorator pattern, isn't suitable for my problem). So please note that I'm not creating my own text rendering engine, I just use these classes to store data. Because I still haven't been able to find a solution to this problem I'd like to ask this question again: how would you design a styles class like this? And why would you do that? Thanks on forehand!

• How do I keep a 3D model on the screen in OpenGL?

  - by NoobScratcher

  I'm trying to keep a 3D model on the screen by placing my glDrawElement functions inside the draw function with the declarations at the top of .cpp. When I render the model, the model attaches it self to the current vertex buffer object. This is because my whole graphical user interface is in 2D quads except the window frame. Is there a way to avoid this from happening? or any common causes of this? Creating the file object: int index = IndexAssigner(1, 1); //make a fileobject and store list and the index of that list in a c string ifstream file (list[index].c_str() ); //Make another string //string line; points.push_back(Point()); Point p; int face[4]; Model rendering code: int numfloats = 4; float* point=reinterpret_cast<float*>(&points[0]); int num_bytes=numfloats*sizeof(float); cout << "Size Of Point" << sizeof(Point) << endl; GLuint vertexbuffer; glGenVertexArrays(1, &vao[3]); glGenBuffers(1, &vertexbuffer); glBindBuffer(GL_ARRAY_BUFFER, vertexbuffer); glBufferData(GL_ARRAY_BUFFER, points.size()*sizeof(points), points.data(), GL_STATIC_DRAW); glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, num_bytes, &points[0]); glEnableClientState(GL_VERTEX_ARRAY); glVertexPointer(3, GL_FLOAT, points.size(), &points[0]); glEnableClientState(GL_INDEX_ARRAY); glIndexPointer(GL_FLOAT, faces.size(), faces.data()); glEnableVertexAttribArray(0); glDrawElements(GL_QUADS, points.size(), GL_UNSIGNED_INT, points.data()); glDrawElements(GL_QUADS, faces.size(), GL_UNSIGNED_INT, faces.data());

• Uses of persistent data structures in non-functional languages

  - by Ray Toal

  Languages that are purely functional or near-purely functional benefit from persistent data structures because they are immutable and fit well with the stateless style of functional programming. But from time to time we see libraries of persistent data structures for (state-based, OOP) languages like Java. A claim often heard in favor of persistent data structures is that because they are immutable, they are thread-safe. However, the reason that persistent data structures are thread-safe is that if one thread were to "add" an element to a persistent collection, the operation returns a new collection like the original but with the element added. Other threads therefore see the original collection. The two collections share a lot of internal state, of course -- that's why these persistent structures are efficient. But since different threads see different states of data, it would seem that persistent data structures are not in themselves sufficient to handle scenarios where one thread makes a change that is visible to other threads. For this, it seems we must use devices such as atoms, references, software transactional memory, or even classic locks and synchronization mechanisms. Why then, is the immutability of PDSs touted as something beneficial for "thread safety"? Are there any real examples where PDSs help in synchronization, or solving concurrency problems? Or are PDSs simply a way to provide a stateless interface to an object in support of a functional programming style?

• How do I require use of the 5 GHz band when connecting to a Wireless N access point?

  - by cqcallaw

  What is says in the topic: there's a Wireless N access point to which I'd like to connect using the 5 GHz band exclusively. How does one accomplish this? Using the directive band=a in the connection configuration file in /etc/NetworkManager/system-connections doesn't seem to affect anything (/var/log/syslog still shows attempts by wpa_supplicant to connect using the 2.4 GHz band), and running iwconfig wlan0 freq 5G per this question results in the following error: Error for wireless request "Set Frequency" (8B04) : SET failed on device wlan0 ; Invalid argument. [Edit] I'm hoping the answer won't depend on the hardware in use, but here's some information about the hardware, just in case: System is an Asus ZenBook Prime UX31A-DB51, running Ubuntu 12.04. lspci output: 00:00.0 Host bridge: Intel Corporation Ivy Bridge DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) 00:04.0 Signal processing controller: Intel Corporation Device 0153 (rev 09) 00:14.0 USB controller: Intel Corporation Panther Point USB xHCI Host Controller (rev 04) 00:16.0 Communication controller: Intel Corporation Panther Point MEI Controller #1 (rev 04) 00:1a.0 USB controller: Intel Corporation Panther Point USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation Panther Point High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 1 (rev c4) 00:1c.1 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 2 (rev c4) 00:1d.0 USB controller: Intel Corporation Panther Point USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation Panther Point LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation Panther Point 6 port SATA Controller [AHCI mode] (rev 04) 00:1f.3 SMBus: Intel Corporation Panther Point SMBus Controller (rev 04) 00:1f.6 Signal processing controller: Intel Corporation Panther Point Thermal Management Controller (rev 04) 02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6235 (rev 24) The driver for the wireless interface is iwlwifi.

• How bad is it to have two methods with the same name but different signatures in two classes?

  - by Super User

  I have a design problem related to a public interface, the names of methods, and the understanding of my API and code. I have two classes like this: class A: ... function collision(self): .... ... class B: .... function _collision(self, another_object, l, r, t, b): .... The first class has one public method named collision, and the second has one private method called _collision. The two methods differs in argument type and number. As an example let's say that _collision checks if the object is colliding with another object with certain conditions l, r, t, b (collide on the left side, right side, etc) and returns true or false. The public collision method, on the other hand, resolves all the collisions of the object with other objects. The two methods have the same name because I think it's better to avoid overloading the design with different names for methods that do almost the same thing, but in distinct contexts and classes. Is this clear enough to the reader or I should change the method's name?

• Will proprietary software-based sound enhancements work with Ubuntu? (BeatsAudio, Dolby)

  - by LiveWireBT

  This question is targeted at mainstream or gamer-grade software-based audio/sound enhancements, found in highly integrated computing and entertainment systems like laptops, tablets and smartphones. These are mostly marketed with fancy badges of known audio-releated brands on the product or packaging, while being mostly uncertain about the actual implementation or components used and poorly differentiated from the general audio capabilities of the system or device. This question is not about actual hardware like speakers. If your headphones are not properly detected, your speakers are assigned wrong, work partially or not at all then your soundcard or chip is not properly detected and you should take a look at troubleshooting audio issues. This question is also not about enthusiast or recording-grade hardware like recording interfaces, amplifiers and DACs in a variety of formfactors. And this question is also not about audio encoding and playback of different audio formats like Dolby Digital, Dolby TrueHD and DTS. Most of these may be subject to patents and licensing, see restricted formats. If you are just searching for an equalizer, please take a look at this question: Is there any Sound enhancers/equalizer? Simply speaking: Every feature where you would flip a switch or check a box in a fancy looking interface in Windows that makes the sound change from neutral to fancy.

• Install Mac OS Lion on Macbook with existing Ubuntu 12.04 dual boot

  - by kash

  I don't usually create my own questions, because I can find what I need through other people's questions. However, this one doesn't seem to be anywhere, except in one place where someone is talking about not using Apple hardware. So here it goes. I am using Apple hardware. I have a MacBook 1,1 with Intel Core2Duo running Ubuntu Precise Pangolin flawlessly. I never considered starting with Mac OSx and dual-booting because I never liked Mac OS. Now that I'm realizing that the only way I'm going to be able to run my DAW (Reaper) nicely and use a Firewire recording interface is to run Mac OSx, I'm considering it again. I want to go the opposite direction of most people and install Mac OSx next to an existing Ubuntu installation and have a boot menu with refit. I've installed refit in Ubuntu and I've converted the .dmg file for Mac OS Lion to a .iso file. Now, should I mount the .iso in Ubuntu and run it there, or burn a DVD and restart? I'm trying to gauge how to do this without hurting my existing Ubuntu installation. I will of course keep looking for existing answers in the meantime.

• Need advice for approach for a web-based app that loads excel worksheet but exposes only the charts

  - by John

  I'm looking for suggestions on the Visual Studio approach to take for a web application that is in the conceptual stage. My environment has a lot of tools: Windows Server 2008 R2 Standard 64bit Visual Studio 2010 Professional Edition Sharepoint 2010 Server Enterprise Edition SQL Server 2008 R2 Office 2010 Professional I know I will need this app to retrieve data from a database (or a web service - not sure exactly at this point). The data needs to be placed in an Excel workbook dynamically. The app will need to have a nice user interface (standard web controls - perhaps with some Javascript effects). The Excel ribbon and worksheet grid will need to be hidden. Some web control(s) will cause the Excel chart(s) to be rendered. I am thinking this sounds like Visual Studio Tools for Office (VSTO) so as to leverage .Net and hide Excel. Can you offer suggestions regarding: One ASP.Net Web App Project One Class Library Project for Excel or perhaps which one of the several different Excel 2010 project types (addin, template, document) Would Excel Services for Sharepoint be useful (or required) ? I am feeling a little overwhelmed with so many choices at this early stage of conceptualizing the app. Can you suggest some ideas for this sort of thing? Also, I am a bit more experienced with C# but I've read VB.Net is better for work with the Excel object model. What are general advises with regard to tool choice and overall approach tradeoffs?

• Best Architecture for ASP.NET WebForms Application

  - by stack man

  I have written an ASP.NET WebForms portal for a client. The project has kind of evolved rather than being properly planned and structured from the beginning. Consequently, all the code is mashed together within the same project and without any layers. The client is now happy with the functionality, so I would like to refactor the code such that I will be confident about releasing the project. As there seems to be many differing ways to design the architecture, I would like some opinions about the best approach to take. FUNCTIONALITY The portal allows administrators to configure HTML templates. Other associated "partners" will be able to display these templates by adding IFrame code to their site. Within these templates, customers can register and purchase products. An API has been implemented using WCF allowing external companies to interface with the system also. An Admin section allows Administrators to configure various functionality and view reports for each partner. The system sends out invoices and email notifications to customers. CURRENT ARCHITECTURE It is currently using EF4 to read/write to the database. The EF objects are used directly within the aspx files. This has facilitated rapid development while I have been writing the site but it is probably unacceptable to keep it like that as it is tightly coupling the db with the UI. Specific business logic has been added to partial classes of the EF objects. QUESTIONS The goal of refactoring will be to make the site scalable, easily maintainable and secure. 1) What kind of architecture would be best for this? Please describe what should be in each layer, whether I should use DTO's / POCO / Active Record pattern etc. 2) Is there a robust way to auto-generate DTO's / BOs so that any future enhancements will be simple to implement despite the extra layers? 3) Would it be beneficial to convert the project from WebForms to MVC?
