• How can I upgrade from Ubuntu 9.10 to 11.10?

  - by Chinnu

  We need to program in CUDA 5.0 which can be installed only on ubuntu 11.10 or 12.04. Our current version, 9.10, is no longer supported, so we chose to proceed with a clean installation. Since we have a shared workstation, we used clonezilla for cloning the system. However, booting from the LiveCD showed an unexpected error. We also tried to install 11.10 in an external HDD by partitioning it, but Gparted could not be installed, and terminated with the error "installArchives() failed" which we couldn't solve even after modifying the sources.list. Is there a way to proceed with this upgrade?

• The Obscured C Competition is Back!

  - by TATWORTH

  The Obscure C competition is back at http://www.ioccc.org/ The Competition is open to the 12/Jan/2012. The aim of the competition is: To write the most Obscure/Obfuscated C program under the rules at http://www.ioccc.org/2011/rules.txt. To show the importance of programming style, in an ironic way. To stress C compilers with unusual code. To illustrate some of the subtleties of the C language. To provide a safe forum for poor C code. :-) Even if you are not a C programmer, it is worth looking at some past entries at: http://en.wikipedia.org/wiki/International_Obfuscated_C_Code_Contest

• Where can I find resources for RPG Character Sprites? [closed]

  - by IcySnow

  I'm developing a turn-based 2D RPG game. Everything's going fine except the lack of characters' sprites such as moving, attacking animation, etc.... By characters I mean both human-like and monster-like creatures. Is there a website providing sprites for free? Or a program (free or paid, whichever is fine) which will let me create sprites from scratch and automatically generate the images? I tried my best to search for one but the best I've managed to find so far is http://spriters-resource.com/. However, is there something else similar and better out there?

• Jumping over non-stationary objects without problems ... 2-D platformer ... how could this be solved? [on hold]

  - by help bonafide pigeons

  You know this problem ... take Super Mario Bros. for example. When Mario/Luigi/etc. comes in proximity with a nearing pipe image an invisible boundary setter must prevent him from continuing forward movement. However, when you jump and move both x and y you are coordinately moving in two dimensions at an exact time. When nearing the pipe in mid-air as you are falling, i.e. implementation of gravity in the computer program "pulling" the image back down, and you do not want them to get "stuck" in both falling and moving. That problem is solved, but how about this one: The player controlling the ball object is attempting to jump and move rightwards over the non-stationary block that moves up and down. How could we measure its top and lower x+y components to determine the safest way for the ball to accurately either fall back down, or catch the ledge, or get pushed down under it, etc.?

• In what order do people build websites?

  - by Corey

  For a website, you need to have an idea, you need to have a design and you need to have data, events and output, right? Whether it be a blog, web app, Q&A site, search engine... Anyway, that is only slightly related to my question. My question is, when designing a website, providing I know the purpose, what should I start with? Should I start with the CSS, design and look&feel using dummy data first, or should I program in the logic, events and output, and style it later? What is the design process of most websites that are built from the ground up?

• How to use GetActiveUniform (in SharpGL)?

  - by frankie

  Generally, guesting is in header. I cannot understand how to use GetActiveUniform function. public void GetActiveUniform(uint program, uint index, int bufSize, int[] length, int[] size, uint[] type, string name); My attempt looks like this (everything is compiled and linked): var uniformSize = new int[1]; var unifromLength = new int[1]; var uniformType = new uint[1]; var uniformName = ""; Gl.GetActiveUniform(Id, index, uniformNameMaxLength[0], unifromLength, uniformSize, uniformType, uniformName); After call I get proper uniformSize, length and type, but not name.

• Is it practically useful to decline GUI for a newbie in Ubuntu?

  - by Kifsif

  My Ubuntu is 12.04. I have just started learning Linux and Ubuntu in particular. To remember commands quicker, I'd like to decline GUI. But there are some problems. I don't know where installed programs are to launch them. For example, I have a pdf file. I know that there is a program to view such files. Should it be the case of GUI, I would just click on the pdf-file, and have a look that I use Document Viewer 3.4.0. Then I would like to launch Firefox Web Browser. Even if I know it is installed, how to find the file to be launched using just CLI is a mystery to me. Could you suggest me anything.

• Should I force users to update an application?

  - by Brian Green

  I'm writing an application for a medium sized company that will be used by about 90% of our employees and our clients. In planning for the future we decided to add functionality that will verify that the version of the program that is running is a version that we still support. Currently the application will forcequit if the version is not among our supported versions. Here is my concern. Hypothetically, in version 2.0.0.1 method "A" crashes and burns in glorious fashion and method "B" works just fine. We release 2.0.0.2 to fix method A and deprecate version 0.1. Now if someone is running 0.1 to use method B they will be forced to update to fix something that isn't an issue for them right now. My question is, will the time saved not troubleshooting old, unsupported versions outweigh the cost in usability?

• Flowchart with subroutine

  - by Jordy

  I am not really sure how to correctly describe my question, so please forgive me if this is a duplicate. I am creating a flowchart for my program where I implement a method. Let's assume I call this method someMethod. The C code could look something like this: bool someMethod(int Foo, int Bar) { foo += 5; bar -= 5; return (foo == bar); } This means that my flowchart will have a subroutine block where I call this function. But how do I correctly show the reader which integers I pass? And when I create the flowchart of "someMethod", I face a similar problem: how do I correctly show the reader that Foo and Bar are passed parameters?

• Provincial Forum & the Best of Oracle OpenWorld for Public Sector

  - by user511693

            Provincial Ministries, Crowns and Agencies are transforming in an effort to meet increasing service expectations from citizens, legislative mandates, and current economic pressures. There is a need to be more efficient and accountable, providing services and information to constituents expeditiously and cost-effectively. However, legacy information systems typically support single program functions. These disparate systems pose a complex canvas upon which to compose a more efficient government systems landscape. Please join your fellow government leaders and Oracle on December 6, 2011 to discuss these challenges and learn how government agencies are leveraging IT as a core tool to streamline multi-organization operations thereby delivering a more cost-effective, citizen- centric, and sustainable government.

• Deferent ways of solving problems in code.

  - by Erin

  I now program in C# for a living but before that I programmed in python for 5 years. I have found that I write C# very that most examples I see on the web. Rather then writing things like: foreach (string bar in foo) { //bar has something doen to it here } I write code that looks like this. foo.ForEach( c => c.someActionhere() ) Or var result = foo.Select( c => { //Some code here to transform the item. }).ToList(); I think my using code like above came form my love of map and reduce in python while not exactly the same thing the concepts are close. Now it's time for my question. What concepts do you take and move with you from language to language. That allow you to solve a problem in a way that is not the normal accepted solution in that language?

• Music player that uses an alarm function with multiple time settings

  - by Mat

  I have tried many different players searching for one with a specific feature that I would think would be easy. Simply, I want to play MP3 primarily. I would like to play a radio stream on Thursdays from 11:00 am until 12:00 pm, then return to playing MP3. Also, because I am in the Husker state, I would like to program another stream to start at game time on Saturdays and end several hours later, resuming my MP3 play until 11:00 am Thursday. Does anyone have a simple solution for me?

• How can you represent equip-able items in a 2d game?

  - by ThePlan

  I've been working on an item system for a post-apocalyptic RPG, with diablo as inspiration, and it would be awesome if I could visually represent an item that can be equipped on the player sprite. I was thinking you could have a player sprite with certain animations, then the equipped item would be drawn as if it was on the player with the same animations, so it syncs with the player animations but that couldn't work very smoothly, I imagine there's a better system. How can you graphically represent an item worn on the player, which moves like he does, and looks as if he's wearing it? I'm not asking you how to do it in framework X or platform X (altho if you REALLY need it, I'm using Allegro 5 with codeblocks on win XP) but instead I'm asking you how to generally program such an idea.

• How To Remove Authorized PCs from Your Windows Store Account

• What's the correct approach for passing data from several models into a service?

  - by Doug Chamberlain

  I have an AccountModel and a page where the user can upload a file. What I would like to have happen is when the user uploads the file. The PageController does something like the following. this is a quick attempt just written in the question to illustrate my question. public class PageController : Controller { private Service service; public ActionResult Upload(HttpPostedFileBase f){ service.savefile(f,_AccountModel_whatever.currentlyloggedinuser.taxid) } } public class Service { // abunch of validation and error checking to make sure the file is good to store } Wouldn't this approach be in bad practice? Since I'm making my controller dependent on the existence of th AccountModel? This will become a HUGE program over the next few years, and I really want to maximize the quality of the framework now.

• What is a good design pattern and terminology for decoupling output?

  - by User

  I have a program where I want to save some data record. And I want the output type to be flexible such that I could save the data record to a text file, xml file, database, push to a webservice. My take on it would be to create an interface such as DataStore with a Save() method, and the concrete subclasses such as TextFileDataStore, DatabaseDataStore, etc. What is the proper name/terminology for this type of pattern (I'm using the term "DataStore", log4net names things "appenders", .net they talk about "providers" and "persistence")? I want to come up with good class names (and method names) that fit with a convention if there is one. can you point me to a decent example, preferably in C#, C++, or java? Update Managed to find this stack overflow question, Object persistence terminology: 'repository' vs. 'store' vs. 'context' vs. 'retriever' vs. (…), which captures the terminology part of my question pretty well although there's not a decent answer yet.

• Keyboad layout: In 13.10, modified symbols do not apply

  - by MPi

  I like to tweak my Colemak layout a bit, so I changed /usr/share/X11/xkb/symbols/us to contain my changes. Sure, they get lost on an upgrade, but that is not very often. After upgrading to 13.10, this does not work anymore. I changed the file, but the changes are not applied. Neither when I use the settings program, nor when I issue setxkbmap 'us(colemak)' directly. Where is this data stored now, is there some kind of cache?

• After installing Windows XP I can't boot into Ubuntu 12.04 LTS

  - by Osama

  I know that this issue may have been happened to many people and answered many times. For some reason, I had to install Windows XP beside Ubuntu 12.04 LTS. Once I did that, I'm no longer able to log on to my Ubuntu. The booting list screen doesn't show up. I tried some ways to fix that, one was to try Boot Repair (of course after opening Ubuntu live from a USB), however, the program didn't open after the installation had finished !! So how can I fix that? I hope you guys stick a little with my problem until it is solved

• How to get started with programming

  - by S.M.

  I have never programmed before. In the 5th grade, I did write very elementary programs using BASIC and that was 7 year back. I wish to learn how to program and I was wondering if someone could please suggest how to get started. For example, I do not know enough to form a judgement on what language should be appropriate to get started. What programming language would you suggest to get started with programming? What are the resources to learn the language you recommend.

• Randomization of biomes

  - by user24527

  You know how in Minecraft, the World is ever-expanding and all the biomes are randomized? My generalized question is: In relation to a space simulation that is also ever-expanding as the player moves about the world, how would one go about programming this randomization in Java? My real question is: Could I get a simplified example broken down into these example classes: astroids (This would include how many astroids there are, their positioning in space, their size, how often the larger astroids occur, how close they are to each other, the limitations of how many of the large asteroids can be in one field, how often astroid fields are generated, etc.) star-types (size, color, type, how often they occur, where hey occur, etc.) inhabitable-planets (size, positioning, how often they're generated, where they are generated, etc.) This would be very helpful currently since I wish to make a simplified version of such a program.
