  • How do I free up more space in /boot?

    - by user6722
    My /boot partition is nearly full and I get a warning every time I reboot my system. I already deleted old kernel packages (linux-headers...), actually I did that to install a newer kernel version that came with the automatic updates. After installing that new version, the partition is nearly full again. So what else can I delete? Are there some other files associated to the old kernel images? Here is a list of files that are on my /boot partition: :~$ ls /boot/ abi-2.6.31-21-generic lost+found abi-2.6.32-25-generic memtest86+.bin abi-2.6.38-10-generic memtest86+_multiboot.bin abi-2.6.38-11-generic System.map-2.6.31-21-generic abi-2.6.38-12-generic System.map-2.6.32-25-generic abi-2.6.38-8-generic System.map-2.6.38-10-generic abi-3.0.0-12-generic System.map-2.6.38-11-generic abi-3.0.0-13-generic System.map-2.6.38-12-generic abi-3.0.0-14-generic System.map-2.6.38-8-generic boot System.map-3.0.0-12-generic config-2.6.31-21-generic System.map-3.0.0-13-generic config-2.6.32-25-generic System.map-3.0.0-14-generic config-2.6.38-10-generic vmcoreinfo-2.6.31-21-generic config-2.6.38-11-generic vmcoreinfo-2.6.32-25-generic config-2.6.38-12-generic vmcoreinfo-2.6.38-10-generic config-2.6.38-8-generic vmcoreinfo-2.6.38-11-generic config-3.0.0-12-generic vmcoreinfo-2.6.38-12-generic config-3.0.0-13-generic vmcoreinfo-2.6.38-8-generic config-3.0.0-14-generic vmcoreinfo-3.0.0-12-generic extlinux vmcoreinfo-3.0.0-13-generic grub vmcoreinfo-3.0.0-14-generic initrd.img-2.6.31-21-generic vmlinuz-2.6.31-21-generic initrd.img-2.6.32-25-generic vmlinuz-2.6.32-25-generic initrd.img-2.6.38-10-generic vmlinuz-2.6.38-10-generic initrd.img-2.6.38-11-generic vmlinuz-2.6.38-11-generic initrd.img-2.6.38-12-generic vmlinuz-2.6.38-12-generic initrd.img-2.6.38-8-generic vmlinuz-2.6.38-8-generic initrd.img-3.0.0-12-generic vmlinuz-3.0.0-12-generic initrd.img-3.0.0-13-generic vmlinuz-3.0.0-13-generic initrd.img-3.0.0-14-generic vmlinuz-3.0.0-14-generic Currently, I'm using the 3.0.0-14-generic kernel.

  • New release of Microsoft All-In-One Code Framework is available for download - March 2011

    - by Jialiang
    A new release of Microsoft All-In-One Code Framework is available on March 8th. Download address: http://1code.codeplex.com/releases/view/62267#DownloadId=215627 You can download individual code samples or browse code samples grouped by technology in the updated code sample index. If it’s the first time that you hear about Microsoft All-In-One Code Framework, please read this Microsoft News Center article http://www.microsoft.com/presspass/features/2011/jan11/01-13codeframework.mspx, or watch the introduction video on YouTube http://www.youtube.com/watch?v=cO5Li3APU58, or read the introduction on our homepage http://1code.codeplex.com/. -------------- New Silverlight code samples CSSLTreeViewCRUDDragDrop Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215808 The code sample was created by Amit Dey. It demonstrates a custom TreeView with added functionalities of CRUD (Create, Read, Update, Delete) and drag-and-drop operations. Silverlight TreeView control with CRUD and drag & drop is a frequently asked programming question in Silverlight  forums. Many customers also requested this code sample in our code sample request service. We hope that this sample can reduce developers' efforts in handling this typical programming scenario. The following blog article introduces the sample in detail: http://blogs.msdn.com/b/codefx/archive/2011/02/15/silverlight-treeview-control-with-crud-and-drag-amp-drop.aspx. CSSL4FileDragDrop and VBSL4FileDragDrop Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215809 http://1code.codeplex.com/releases/view/62253#DownloadId=215810 The code sample demonstrates the new drag&drop feature of Silverlight 4 to implement dragging picures from the local file system to a Silverlight application.   Sometimes we want to change SiteMapPath control's titles and paths according to Query String values. And sometimes we want to create the SiteMapPath dynamically. This code sample shows how to achieve these goals by handling SiteMap.SiteMapResolve event. CSASPNETEncryptAndDecryptConfiguration, VBASPNETEncryptAndDecryptConfiguration Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215027 http://1code.codeplex.com/releases/view/62253#DownloadId=215106 In this sample, we encrypt and decrypt some sensitive information in the config file of a web application by using the RSA asymmetric encryption. This project contains two snippets. The first one demonstrates how to use RSACryptoServiceProvider to generate public key and the corresponding private key and then encrypt/decrypt string value on page. The second part shows how to use RSA configuration provider to encrypt and decrypt configuration section in web.config of web application. connectionStrings section in plain text: Encrypted connectionString:  Note that if you store sensitive data in any of the following configuration sections, we cannot encrypt it by using a protected configuration provider <processModel> <runtime> <mscorlib> <startup> <system.runtime.remoting> <configProtectedData> <satelliteassemblies> <cryptographySettings> <cryptoNameMapping> CSASPNETFileUploadStatus Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215028 I believe ASP.NET programmers will like this sample, because in many cases we need customers know the current status of the uploading files, including the upload speed and completion percentage and so on. Under normal circumstances, we need to use COM components to accomplish this function, such as Flash, Silverlight, etc. The uploading data can be retrieved in two places, the client-side and the server-side. For the client, for the safety factors, the file upload status information cannot be got from JavaScript or server-side code, so we need COM component, like Flash and Silverlight to accomplish this, I do not like this approach because the customer need to install these components, but also we need to learn another programming framework. For the server side, we can get the information through coding, but the key question is how to tell the client results. In this case, We will combine custom HTTPModule and AJAX technology to illustrate how to analyze the HTTP protocol, how to break the file request packets, how to customize the location of the server-side file caching, how to return the file uploading status back to the client and so on . CSASPNETHighlightCodeInPage, VBASPNETHighlightCodeInPage Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215029 http://1code.codeplex.com/releases/view/62253#DownloadId=215108 This sample imitates a system that needs display the highlighted code in an ASP.NET page . As a matter of fact, sometimes we input code like C# or HTML in a web page and we need these codes to be highlighted for a better reading experience. It is convenient for us to keep the code in mind if it is highlighted. So in this case, the sample shows how to highlight the code in an ASP.NET page. It is not difficult to highlight the code in a web page by using String.Replace method directly. This  method can return a new string in which all occurrences of a specified string in the current instance are replaced with another specified string. However, it may not be a good idea, because it's not extremely fast, in fact, it's pretty slow. In addition, it is hard to highlight multiple keywords by using String.Replace method directly. Sometimes we need to copy source code from visual studio to a web page, for readability purpose, highlight the code is important while set the different types of keywords to different colors in a web page by using String.Replace method directly is not available. To handle this issue, we need to use a hashtable variable to store the different languages of code and their related regular expressions with matching options. Furthermore, define the css styles which used to highlight the code in a web page. The sample project can auto add the style object to the matching string of code. A step-by-step guide illustrating how to highlight the code in an ASP.NET page: 1. the HighlightCodePage.aspx page Choose a type of language in the dropdownlist control and paste the code in the textbox control, then click the HighLight button. 2.  Display the highlighted code in an ASP.NET page After user clicks the HighLight button, the highlighted code will be displayed at right side of the page.        CSASPNETPreventMultipleWindows Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215032 This sample demonstrates a step-by-step guide illustrating how to detect and prevent multiple windows or tab usage in Web Applications. The sample imitates a system that need to prevent multiple windows or tabs to solve some problems like sharing sessions, protect duplicated login, data concurrency, etc. In fact, there are many methods achieving this goal. Here we give a solution of use JavaScript, Sample shows how to use window.name property check the correct links and throw other requests to invalid pages. This code-sample use two user controls to make a distinction between base page and target page, user only need drag different controls to appropriate web form pages. so user need not write repetitive code in every page, it will make coding work lightly and convenient for modify your code.  JSVirtualKeyboard Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215093 This article describes an All-In-One framework sample that demonstrates a step-by-step guide illustrating how to build a virtual keyboard in your HTML page. Sometimes we may need to offer a virtual keyboard to let users input something without their real keyboards. This scenario often occurs when users will enter their password to get access to our sites and we want to protect the password from some kinds of back-door software, a Key-logger for example, and we will find a virtual keyboard on the page will be a good choice here. To create a virtual keyboard, we firstly need to add some buttons to the page. And when users click on a certain button, the JavaScript function handling the onclick event will input an appropriated character to the textbox. That is the simple logic of this feature. However, if we indeed want a virtual keyboard to substitute for the real keyboard completely, we will need more advanced logic to handle keys like Caps-Lock and Shift etc. That will be a complex work to achieve. CSASPNETDataListImageGallery Download: http://1code.codeplex.com/releases/view/62261#DownloadId=215267 This code sample demonstrates how to create an Image Gallery application by using the DataList control in ASP.NET. You may find the Image Gallery is widely used in many social networking sites, personal websites and E-Business websites. For example, you may use the Image Gallery to show a library of personal uploaded images on a personal website. Slideshow is also a popular tool to display images on websites. This code sample demonstrates how to use the DataList and ImageButton controls in ASP.NET to create an Image Gallery with image navigation. You can click on a thumbnail image in the Datalist control to display a larger version of the image on the page. This sample code reads the image paths from a certain directory into a FileInfo array. Then, the FileInfo array is used to populate a custom DataTable object which is bound to the Datalist control. This code sample also implements a custom paging system that allows five images to be displayed horizontally on one page. The following link buttons are used to implement a custom paging system:   •     First •     Previous •     Next •     Last Note We recommend that you use this method to load no more than five images at a time. You can also set the SelectedIndex property for the DataList control to limit the number of the thumbnail images that can be selected. To indicate which image is selected, you can set the SelectedStyle property for the DataList control. VBASPNETSearchEngine Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215112 This sample shows how to implement a simple search engine in an ASP.NET web site. It uses LIKE condition in SQL statement to search database. Then it highlights keywords in search result by using Regular Expression and JavaScript. New Windows General code samples CSCheckEXEType, VBCheckEXEType Downloads: http://1code.codeplex.com/releases/view/62253#DownloadId=215045 http://1code.codeplex.com/releases/view/62253#DownloadId=215120 The sample demonstrates how to check an executable file type.  For a given executable file, we can get 1 whether it is a console application 2 whether it is a .Net application 3 whether it is a 32bit native application. 4 The full display name of a .NET application, e.g. System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089, processorArchitecture=MSIL New Internet Explorer code samples CSIEExplorerBar, VBIEExplorerBar Downloads: http://1code.codeplex.com/releases/view/62253#DownloadId=215060 http://1code.codeplex.com/releases/view/62253#DownloadId=215133 The sample demonstrates how to create and deploy an IE Explorer Bar which could list all the images in a web page.

  • High number of ethernet errors. Tool for testing the ethernet card?

    - by Fabio Dalla Libera
    I have an Asus Sabertooth X79. I often get corrupted files. I checked the RAM, but memtest finds no errors. To avoid the possibility of disk errors, I tried copying the files to tmpfs. If I copy from the network, I get md5sum mismatches about once every 10 times using a 6Gb file. Copying from RAM to RAM, I didn't get mismatches. I get a very high number of errors in ifconfig (compared to others PCs I just took as reference, which have 0 with much more traffic). Here is an example RX packets:13972848 errors:200 dropped:0 overruns:0 frame:101 The motherboard is new, but do you think there're some problems with it? What could I use to test the (integrated) network adapter? What else do you think I should double check? --edit-- I tried another NIC, it gives a lot of Corrupted MAC on Input. Disconnecting: Packet corrupt lost connection. I noticed that another PC downloads at 11.1MB/s without problems. This pc at 66.0 MB/s. Is there any way to try to limit the speed?

  • How to work around a possible XNA Game Studio or Windows Phone SDK install failure on Windows 8

    - by Laurent Bugnion
    I am not sure if you guys know Aaron Stebner. Aaron works at Microsoft, and has pulled thorns from my side many many times already. His blog is at http://blogs.msdn.com/b/astebner and it is a gold mine of tips and tricks to debug and solve many cryptic issues happening during installation and removal of programs. For example, Aaron taught me how to remove programs that do not appear in the Programs and Features list, amongst many other things. The last nugget I used from Aaron’s blog saved my butt just before a presentation where I had to run both Visual Studio 10 with the Windows Phone SDK, and Visual Studio 11 for WinRT development. Of course this had to be on Windows 8. Unfortunately when you install the Windows Phone SDK on Windows 8, you may (or may not, I saw both scenarios) encounter an issue with XNA, and the installation fails. Unfortunately, even if you don’t use XNA in your apps, this will prevent even normal Windows Phone app development. Fortunately, Aaron has a fix for that. I hope that this helps spread the word, and increase Aaron’s blog’s visibility! Happy coding, Laurent   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

  • AutoHotkey cannot interact with Windows 8 Windows&hellip;or can it!

    - by deadlydog
    If you’ve installed Windows 8 and are trying to use AutoHotkey (AHK) to interact with some of the Winodws 8 Windows (such as the Control Panel for example), or with apps that need to be Ran As Administrator, then you’ve likely become very frustrated as I did to discover that AHK can not send any commands (keyboard or mouse input) to these windows.  This was a huge concern as I often need to run Visual Studio as an administrator and wanted my hotkeys and hotstrings to work in Visual Studio.  After a day of fighting I finally realized the answer (and it’s pretty obvious once you think about it).  If you want AHK to be able to interact with Windows 8 Windows or apps running as administrator, then you also need to have your AHK script Run As Administrator. If you are like me then you probably have your AHK scripts set to run automatically at login, which means you don’t have the opportunity to right-click on the script and manually tell it to Run As Administrator.  Luckily the work around is simple.  First, if you want to have your AHK script (or any program for that matter) run when you log in, create a shortcut to the application and place the shortcut in: C:\Users\[User Name]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup Note that you will need to replace “[User Name]” with your username, and that “AppData” is a hidden folder so you’ll need to turn on viewing hidden folders to see it.  So by placing that shortcut there Windows will automatically run your script when you log on.  Now, to get it to run as an administrator by default, right-click on the shortcut and go to Properties.  Under the Shortcut tab, click on the “Advanced…” button and check off “Run as administrator”.  That’s it.  Now when you log onto Windows your script will automatically start up, running as an administrator; allowing it to interact with any application and window like you had expected it to in the first place.   Happy coding!

  • Logical progressions through the job market

    - by Philluminati
    I'm 5 years out of a unrecognised university where I did Software Engineering. First job was VB.NET, one job was Python, Linux and Web development. I feel cast as a web developer. I'd love a role doing C but no one is interested in juniors if the applicant hasn't got 3 years of C development experience already. I've done some C and a drop of open source coding but I'll never have the confidence to convince someone I know absolutely what I'm doing. Do I just spend more and more time letting life pass me by as I sit in my room on a friday night writing a C problem "for the sake of learning more C" Basically I'm just not sure I want to continue my career if it's going to involve nothing but high level, machine abstracted, business logic and as interested as I am in low level development and enjoy reading books by Taunembaum I struggle to see how I can make the jump and I just feel life would be easier if I got a job in a cafe in Amsterdam rolling spliffs for customers. My ideal job, being a paid member of the Fedora development team seems so far away, without anyone to pay me to learn the skills to get there, and the only way would be to literally spend weeks and weeks of my life contributing code without recognition for free and without any guarentees at the end. Not that I've contributed anything at all so far. Are there any career paths that are logically set out so that jumping between roles is "correctly" incremental and where hard work and learning does eventually lead to the kind of places I might want to go? [ and also getting paid at the same time? ]

  • VHOST not working in Apache

    - by Starx
    I got a LAMP server working in Ubuntu 11.04. Now the problem is that the websites have to enabled and disabled from the terminal. All all of them have to be accessed from http://localhost which is not so much efficient. So I created a VHOSTS, using some tutorials off the net. Here is the coding for it <VirtualHost *:80> ServerAdmin webmaster@localhost Servername site.com ServerAlias www.site.com DocumentRoot /home/starx/public_html/site/public <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /home/starx/public_html/site/public> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> nGen ErrorLog ${APACHE_LOG_DIR}/site-error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

  • Microsoft Silverlight Analytics Framework - Day 2 Part 2 of MIX 2010

    - by GeekAgilistMercenary
    I went to the session on Microsoft Silverlight Analytics Framework (MSAF) today while here at MIX 2010.  It was a great walk through the features, ideas, and what the end goal is.  Michael Scherotter did a great job of lining up the ideas, intentions, and the functional ideas behind the framework. The framework is built around the Silverlight Behaviors.  If you aren't sure what behaviors are, check out these entries from Nikhilk.net Silverlight Behaviors, Silverlight 3 Drag Behavior, An Introduction to Behaviors, Triggers, and Actions, and of course the MSDN Documentation on the matter. Some of the key features of the framework is to support out-of-browser scenarios, which works perfectly with out Webtrends DX Web Services.  Offline scenarios, which again, we have worked toward supporting at Webtrends DC Web Services via caching and other criteria as needed.  Another feature that I was really stoked about is the Microsoft Expression Blend integration that removes the need for coding, thus simplifying the addition of analytics components based on events or other actions within a Silverlight Application.  This framework also easily supports A/B Testing (again, something we do quit a bit of at Webtrends with Webtrends Optimize. The last thing I really wanted to point out was the control support that this framework has support in already from Telerik RadControls, Smooth Streaming Media Element, and Microsoft Silverlight Media Framework Player 1.0.  These are implemented with behaviors and handlers exposed via MEF (Managed Extensibility Framework). All in all, great second day, great analytics framework for Silverlight, and great presentation.  Until tomorrow, adieu. For this original entry and all sorts of other technical gibberish I write, check out my other blog Agilist Mercenary.

  • Gray "apply" button in NetworkManager openvpn connection window

    - by user20627
    I installed all the necessary packages for the networkmanager-openvpn function to function. The openvpn-connection-setting are successfully imported into the networkmanger via the conf file but the apply button is grayed out, so that actually saving and using the connection isn't possible? Does anyone know, where the problem is? It's a fresh install of Ubuntu 10.10 after the upgrade from 10.04 sent the networkmanger down the drain. I was told the following: Sounds like a policy issue. read this thread: http://ubuntuforums.org/showthread.php?t=1616355 look carefully in the file mentioned, at the element. What is there ? "No" will cause the action detailed to be unavailable. Ideally "yes" or "auth_admin_keep" should be there. They will either allow all access, or prompt for a admin password. The above does not seem to work for me - It still has a gray apply button. If I choose a file for User certificate as well as CA Certificate "which is all openvpn supplies and needs" and a key file it will allow me to click apply - but obviously wont connect. :l I am at a lost end.

  • Need recommendation for transferring ASP.NET MVC skills to PHP

    - by Tuck
    I am looking to translate my skills in .NET to PHP - specifically in regards to ASP.NET MVC. At work I am currently using .NET MVC 2.0 on a variety of projects and thoroughly enjoy the platform. Specifically I enjoy the very minimal configuration required to get a project up and running (just create the project, define routes, and start coding), as well as the ability for controller actions to return different items (i.e. ActionResult, JsonResult). Another piece I really like is the way the view/model interaction can be handled. For example I like being able to call return View(model) and having a view page (.aspx) load and having the full model object available to the view, regardless of the model type. I'm looking for a PHP implementation of MVC that is the most similiar to what I am already familiar with. I don't anything apart from the MVC functionality. I've looked at Zend, Symfony, CodeIgniter, etc. and, while they look like they'll be fun to play with in the future, they provide much more functionality than I need. I'd prefer to write my own DAL, form helpers, delegate handlers, authentication/ACL pieces, etc. In short, I just need something to handle the routing and view interactions and will worry about the model implementation myself. Can someone please point me to some lightweight code that accomplishes or comes close to accomplishing my objectives above. Or, can someone identify just the portions of a larger framework that do the same (again, I'm not currently interested in implementing something on a big framework, just the MVC portion and want to implement the model portion myself as much as possible). Thanks in advance.

  • Life and Career guidance

    - by Andrei TheGiant Haxtor
    Hello programmers. I have a current dilemma I'm pondering over. I will be graduating from high school with ~60 credits worth of community college work (pre-engineering courses), and I am wondering what would experienced programmers suggest I do with my time since I have all of the bull courses out of the way. Should I start taking computer science/engineering courses or should I take some other courses that interest me?(psych, math) The reason I am asking this is, well , I like doing a lot of self studying, especially relating to software and tech. I don't like to have the pressure of hard classes on me, so I could make up for the time lost doing the CC courses and dive deep in programming and books. I've started getting into programming recently unfortunately, since I didn't have much time b/c of my course load. Right now I am doing Java and messing around with android. I would like to get involved in web&mobile development, operating systems, and finance software. If any of you experienced people could please give me some guidance and words of wisdom, I would greatly appreciated. Sorry that this isn't necessarily related to programming. All the best.

  • Day 6 - Game Menuing Woes and Future Screen Sneak Peeks

    - by dapostolov
    So, after my last post on Day 5 I dabbled with my game class design. I took the approach where each game objects is tightly coupled with a graphic. The good news is I got the menu working but not without some hard knocks and game growing pains. I'll explain later, but for now...here is a class diagram of my first stab at my class structure and some code...   Ok, there are few mistakes, however, I'm going to leave it as is for now... As you can see I created an inital abstract base class called GameSprite. This class when inherited will provide a simple virtual default draw method:        public virtual void DrawSprite(SpriteBatch spriteBatch)         {             spriteBatch.Draw(Sprite, Position, Color.White);         } The benefits of coding it this way allows me to inherit the class and utilise the method in the screen draw method...So regardless of what the graphic object type is it will now have the ability to render a static image on the screen. Example: public class MyStaticTreasureChest : GameSprite {} If you remember the window draw method from Day 3's post, we could use the above code as follows...         protected override void Draw(GameTime gameTime)         {             GraphicsDevice.Clear(Color.CornflowerBlue);             spriteBatch.Begin(SpriteBlendMode.AlphaBlend);             foreach(var gameSprite in ListOfGameObjects)            {                 gameSprite.DrawSprite(spriteBatch);            }             spriteBatch.End();             base.Draw(gameTime);         } I have to admit the GameSprite object is pretty plain as with its DrawSprite method... But ... we now have the ability to render 3 static menu items on the screen ... BORING! I want those menu items to do something exciting, which of course involves animation... So, let's have a peek at AnimatedGameSprite in the above game diagram. The idea with the AnimatedGameSprite is that it has an image to animate...such as ... characters, fireballs, and... menus! So after inheriting from GameSprite class, I added a few more options such as UpdateSprite...         public virtual void UpdateSprite(float elapsed)         {             _totalElapsed += elapsed;             if (_totalElapsed > _timePerFrame)             {                 _frame++;                 _frame = _frame % _framecount;                 _totalElapsed -= _timePerFrame;             }         }  And an overidden DrawSprite...         public override void DrawSprite(SpriteBatch spriteBatch)         {             int FrameWidth = Sprite.Width / _framecount;             Rectangle sourcerect = new Rectangle(FrameWidth * _frame, 0, FrameWidth, Sprite.Height);             spriteBatch.Draw(Sprite, Position, sourcerect, Color.White, _rotation, _origin, _scale, SpriteEffects.None, _depth);         } With these two methods...I can animate and image, all I had to do was add a few more lines to the screens Update Method (From Day 3), like such:             float elapsed = (float) gameTime.ElapsedGameTime.TotalSeconds;             foreach (var item in ListOfAnimatedGameObjects)             {                 item.UpdateSprite(elapsed);             } And voila! My images begin to animate in one spot, on the screen... Hmm, but how do I interact with the menu items using a mouse...well the mouse cursor was easy enough... this.IsMouseVisible = true; But, to have it "interact" with an image was a bit more tricky...I had to perform collision detection!             mouseStateCurrent = Mouse.GetState();             var uiEnabledSprites = (from s in menuItems                                    where s.IsEnabled                                    select s).ToList();             foreach (var item in uiEnabledSprites)             {                 var r = new Rectangle((int)item.Position.X, (int)item.Position.Y, item.Sprite.Width, item.Sprite.Height);                 item.MenuState = MenuState.Normal;                 if (r.Intersects(new Rectangle(mouseStateCurrent.X, mouseStateCurrent.Y, 0, 0)))                 {                     item.MenuState = MenuState.Hover;                     if (mouseStatePrevious.LeftButton == ButtonState.Pressed                         && mouseStateCurrent.LeftButton == ButtonState.Released)                     {                         item.MenuState = MenuState.Pressed;                     }                 }             }             mouseStatePrevious = mouseStateCurrent; So, basically, what it is doing above is iterating through all my interactive objects and detecting a rectangle collision and the object , plays the state animation (or static image).  Lessons Learned, Time Burned... So, I think I did well to start, but after I hammered out my prototype...well...things got sloppy and I began to realise some design flaws... At the time: I couldn't seem to figure out how to open another window, such as the character creation screen Input was not event based and it was bugging me My menu design relied heavily on mouse input and I couldn't use keyboard. Mouse input, is tightly bound with graphic rendering / positioning, so its logic will have to be in each scene. Menu animations would stop mid frame, then continue when the action occured again. This is bad, because...what if I had a sword sliding onthe screen? Then it would slide a quarter of the way, then stop due to another action, then render again mid-slide... it just looked sloppy. Menu, Solved!? To solve the above problems I did a little research and I found some great code in the XNA forums. The one worth mentioning was the GameStateManagementSample. With this sample, you can create a basic "text based" menu system which allows you to swap screens, popup screens, play the game, and quit....basic game state management... In my next post I'm going to dwelve a bit more into this code and adapt it with my code from this prototype. Text based menus just won't cut it for me, for now...however, I'm still going to stick with my animated menu item idea. A sneak peek using the Game State Management Sample...with no changes made... Cool Things to Mention: At work ... I tend to break out in random conversations every-so-often and I get talking about some of my challenges with this game (or some stupid observation about something... stupid) During one conversation I was discussing how I should animate my images; I explained that I knew I had to use the Update method provided, but I didn't know how (at the time) to render an image at an appropriate "pace" and how many frames to use, etc.. I also got thinking that if a machine rendered my images faster / slower, that was surely going to f-up my animations. To which a friend, Sheldon,  answered, surely the Draw method is like a camera taking a snapshot of a scene in time. Then it clicked...I understood the big picture of the game engine... After some research I discovered that the Draw method attempts to keep a framerate of 60 fps. From what I understand, the game engine will even leave out a few calls to the draw method if it begins to slow down. This is why we want to put our sprite updates in the update method. Then using a game timer (provided by the engine), we want to render the scene based on real time passed, not framerate. So even the engine renders at 20 fps, the animations will still animate at the same real time speed! Which brings up another point. Why 60 fps? I'm speculating that Microsoft capped it because LCD's dont' refresh faster than 60 fps? On another note, If the game engine knows its falling behind in rendering...then surely we can harness this to speed up our games. Maybe I can find some flag which tell me if the game is lagging, and what the current framerate is, etc...(instead of coding it like I did last time) Sheldon, suggested maybe I can render like WoW does, in prioritised layers...I think he's onto something, however I don't think I'll have that many graphics to worry about such a problem of graphic latency. We'll see. People to Mention: Well,as you are aware I hadn't posted in a couple days and I was surprised to see a few emails and messenger queries about my game progress (and some concern as to why I stopped). I want to thank everyone for their kind words of support and put everyone at ease by stating that I do intend on completing this project. Granted I only have a few hours each night, but, I'll do it. Thank you to Garth for mailing in my next screen! That was a nice surprise! The Sneek Peek you've been waiting for... Garth has also volunteered to render me some wizard images. He was a bit shocked when I asked for them in 2D animated strips. He said I was going backward (and that I have really bad Game Development Lingo). But, I advised Garth that I will use 3D images later...for now...2D images. Garth also had some great game design ideas to add on. I advised him that I will save his ideas and include them in the future design document (for the 3d version?). Lastly, my best friend Alek, is going to join me in developing this game. This was a project we started eons ago but never completed because of our careers. Now, priorities change and we have some spare time on our hands. Let's see what trouble Alek and I can get into! Tonight I'll be uploading my prototypes and base game to a source control for both of us to work off of. D.

  • Reinstalled Ubuntu 12.04 and now I cannot change preferences like theme, wallpaper, and nautilus preferences

    - by krishnab
    So I just down-rev'd ubuntu from 13.04 back to 12.04 LTS desktop 64 (Precise). I am using Unity. I just reformatted the Ubuntu partition, but kept my home directory intact, and everything seemed to reconnect just fine. No data was lost. However, I found that I cannot seem to change my preferences. So I cannot seem to change my desktop background, no matter how many ways I try--Ubuntu Tweak, Gnome Tweak, system settings. I also cannot change the system GTK+ theme, though apparently I am able to change the windows border theme. Further, I cannot seem to change my Nautilus preferences--so I cannot seem the make the default view a list view, and I cannot make the "single-click" behavior the default. I even went into the nautilus org.gnome.nautilus settings to manually change things, but no luck. I thought it was a permissions issue, so I did a chown on the home folder and on the .gvfs folder. Still no luck. So somewhere there seems to be a permission that I am not catching. Does anyone have any suggestions? Thanks.

  • Problem installing Ubuntu One in Windows XP

    - by Garry
    I've just had to reinstall my Ubuntu One client for Windows XP Service Pack 3 and whenever I do it uninstalls my previous attempt then comed up with the following error message c:\Program Files/ubuntuone\dist\ubuntuone-control-panel-qt.exe This application has failed to start because the application configuration is incorrect. Reinstalling this application may fix this problem. The only option I have is "ok" then nothing happens. I've tried downloading Ubuntu One several times and tried Windows 2000 compatibility mode, Administrator mode and nothing. The only thing that I make happen is for Windows NT 5 mode, a small box appears with nothing showing and nothing else. I really need Ubuntu 1 on my computer as it has everything on it so I'm wondering if I can do anything to make it install or if it's a lost cause. The last time I tried to install U1 on Windows XP I had the same problem but after about 10 tries it installed. I've tried about 30 times now and nothing. My computer is a Dell OptiPlex SX280 with 2gb ram and 340GB Hard disk Intel Pentium 4 HT Processor

  • To write or not to write: Frameworks [closed]

    - by caarlos0
    Today some friends and I started discussing frameworks.. Some of us strongly believe that in 99.9% of cases, writing a new framework is a bad idea. We believe that probably some of the millions of frameworks out there should fit our problem, and if not, some hack, API, or configuration should be enough. If not, we think that contributing to some framework, suggest features or something like that should be the best solution. The 0.1% is when none of the frameworks fit to our case. But, some of us say that it is better to have an "internal corporate framework" (for example), because it's faster to fix issues, creates a 100% fit with the app, because of the "learning" factor (when you improve your skills building a framework), etc. I think that to go out coding frameworks like there's no tomorrow is not the right way. I've seen a lot of small teams building their own framework just to spread the word: "we built our own framework, we rule, bro". Generally, the framework is crap, without any documentation, and only works for their own applications. Opinions are opinions, devs are devs, without the intention to start any kind of flame war, I ask: What do you think about that? What parameters you consider when building a framework? What do you think about all this?

  • Adding and accessing custom sections in your C# App.config

    - by deadlydog
    So I recently thought I’d try using the app.config file to specify some data for my application (such as URLs) rather than hard-coding it into my app, which would require a recompile and redeploy of my app if one of our URLs changed.  By using the app.config it allows a user to just open up the .config file that sits beside their .exe file and edit the URLs right there and then re-run the app; no recompiling, no redeployment necessary. I spent a good few hours fighting with the app.config and looking at examples on Google before I was able to get things to work properly.  Most of the examples I found showed you how to pull a value from the app.config if you knew the specific key of the element you wanted to retrieve, but it took me a while to find a way to simply loop through all elements in a section, so I thought I would share my solutions here.   Simple and Easy The easiest way to use the app.config is to use the built-in types, such as NameValueSectionHandler.  For example, if we just wanted to add a list of database server urls to use in my app, we could do this in the app.config file like so: 1: <?xml version="1.0" encoding="utf-8" ?> 2: <configuration> 3: <configSections> 4: <section name="ConnectionManagerDatabaseServers" type="System.Configuration.NameValueSectionHandler" /> 5: </configSections> 6: <startup> 7: <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" /> 8: </startup> 9: <ConnectionManagerDatabaseServers> 10: <add key="localhost" value="localhost" /> 11: <add key="Dev" value="Dev.MyDomain.local" /> 12: <add key="Test" value="Test.MyDomain.local" /> 13: <add key="Live" value="Prod.MyDomain.com" /> 14: </ConnectionManagerDatabaseServers> 15: </configuration>   And then you can access these values in code like so: 1: string devUrl = string.Empty; 2: var connectionManagerDatabaseServers = ConfigurationManager.GetSection("ConnectionManagerDatabaseServers") as NameValueCollection; 3: if (connectionManagerDatabaseServers != null) 4: { 5: devUrl = connectionManagerDatabaseServers["Dev"].ToString(); 6: }   Sometimes though you don’t know what the keys are going to be and you just want to grab all of the values in that ConnectionManagerDatabaseServers section.  In that case you can get them all like this: 1: // Grab the Environments listed in the App.config and add them to our list. 2: var connectionManagerDatabaseServers = ConfigurationManager.GetSection("ConnectionManagerDatabaseServers") as NameValueCollection; 3: if (connectionManagerDatabaseServers != null) 4: { 5: foreach (var serverKey in connectionManagerDatabaseServers.AllKeys) 6: { 7: string serverValue = connectionManagerDatabaseServers.GetValues(serverKey).FirstOrDefault(); 8: AddDatabaseServer(serverValue); 9: } 10: }   And here we just assume that the AddDatabaseServer() function adds the given string to some list of strings.  So this works great, but what about when we want to bring in more values than just a single string (or technically you could use this to bring in 2 strings, where the “key” could be the other string you want to store; for example, we could have stored the value of the Key as the user-friendly name of the url).   More Advanced (and more complicated) So if you want to bring in more information than a string or two per object in the section, then you can no longer simply use the built-in System.Configuration.NameValueSectionHandler type provided for us.  Instead you have to build your own types.  Here let’s assume that we again want to configure a set of addresses (i.e. urls), but we want to specify some extra info with them, such as the user-friendly name, if they require SSL or not, and a list of security groups that are allowed to save changes made to these endpoints. So let’s start by looking at the app.config: 1: <?xml version="1.0" encoding="utf-8" ?> 2: <configuration> 3: <configSections> 4: <section name="ConnectionManagerDataSection" type="ConnectionManagerUpdater.Data.Configuration.ConnectionManagerDataSection, ConnectionManagerUpdater" /> 5: </configSections> 6: <startup> 7: <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" /> 8: </startup> 9: <ConnectionManagerDataSection> 10: <ConnectionManagerEndpoints> 11: <add name="Development" address="Dev.MyDomain.local" useSSL="false" /> 12: <add name="Test" address="Test.MyDomain.local" useSSL="true" /> 13: <add name="Live" address="Prod.MyDomain.com" useSSL="true" securityGroupsAllowedToSaveChanges="ConnectionManagerUsers" /> 14: </ConnectionManagerEndpoints> 15: </ConnectionManagerDataSection> 16: </configuration>   The first thing to notice here is that my section is now using the type “ConnectionManagerUpdater.Data.Configuration.ConnectionManagerDataSection” (the fully qualified path to my new class I created) “, ConnectionManagerUpdater” (the name of the assembly my new class is in).  Next, you will also notice an extra layer down in the <ConnectionManagerDataSection> which is the <ConnectionManagerEndpoints> element.  This is a new collection class that I created to hold each of the Endpoint entries that are defined.  Let’s look at that code now: 1: using System; 2: using System.Collections.Generic; 3: using System.Configuration; 4: using System.Linq; 5: using System.Text; 6: using System.Threading.Tasks; 7:  8: namespace ConnectionManagerUpdater.Data.Configuration 9: { 10: public class ConnectionManagerDataSection : ConfigurationSection 11: { 12: /// <summary> 13: /// The name of this section in the app.config. 14: /// </summary> 15: public const string SectionName = "ConnectionManagerDataSection"; 16: 17: private const string EndpointCollectionName = "ConnectionManagerEndpoints"; 18:  19: [ConfigurationProperty(EndpointCollectionName)] 20: [ConfigurationCollection(typeof(ConnectionManagerEndpointsCollection), AddItemName = "add")] 21: public ConnectionManagerEndpointsCollection ConnectionManagerEndpoints { get { return (ConnectionManagerEndpointsCollection)base[EndpointCollectionName]; } } 22: } 23:  24: public class ConnectionManagerEndpointsCollection : ConfigurationElementCollection 25: { 26: protected override ConfigurationElement CreateNewElement() 27: { 28: return new ConnectionManagerEndpointElement(); 29: } 30: 31: protected override object GetElementKey(ConfigurationElement element) 32: { 33: return ((ConnectionManagerEndpointElement)element).Name; 34: } 35: } 36: 37: public class ConnectionManagerEndpointElement : ConfigurationElement 38: { 39: [ConfigurationProperty("name", IsRequired = true)] 40: public string Name 41: { 42: get { return (string)this["name"]; } 43: set { this["name"] = value; } 44: } 45: 46: [ConfigurationProperty("address", IsRequired = true)] 47: public string Address 48: { 49: get { return (string)this["address"]; } 50: set { this["address"] = value; } 51: } 52: 53: [ConfigurationProperty("useSSL", IsRequired = false, DefaultValue = false)] 54: public bool UseSSL 55: { 56: get { return (bool)this["useSSL"]; } 57: set { this["useSSL"] = value; } 58: } 59: 60: [ConfigurationProperty("securityGroupsAllowedToSaveChanges", IsRequired = false)] 61: public string SecurityGroupsAllowedToSaveChanges 62: { 63: get { return (string)this["securityGroupsAllowedToSaveChanges"]; } 64: set { this["securityGroupsAllowedToSaveChanges"] = value; } 65: } 66: } 67: }   So here the first class we declare is the one that appears in the <configSections> element of the app.config.  It is ConnectionManagerDataSection and it inherits from the necessary System.Configuration.ConfigurationSection class.  This class just has one property (other than the expected section name), that basically just says I have a Collection property, which is actually a ConnectionManagerEndpointsCollection, which is the next class defined.  The ConnectionManagerEndpointsCollection class inherits from ConfigurationElementCollection and overrides the requied fields.  The first tells it what type of Element to create when adding a new one (in our case a ConnectionManagerEndpointElement), and a function specifying what property on our ConnectionManagerEndpointElement class is the unique key, which I’ve specified to be the Name field. The last class defined is the actual meat of our elements.  It inherits from ConfigurationElement and specifies the properties of the element (which can then be set in the xml of the App.config).  The “ConfigurationProperty” attribute on each of the properties tells what we expect the name of the property to correspond to in each element in the app.config, as well as some additional information such as if that property is required and what it’s default value should be. Finally, the code to actually access these values would look like this: 1: // Grab the Environments listed in the App.config and add them to our list. 2: var connectionManagerDataSection = ConfigurationManager.GetSection(ConnectionManagerDataSection.SectionName) as ConnectionManagerDataSection; 3: if (connectionManagerDataSection != null) 4: { 5: foreach (ConnectionManagerEndpointElement endpointElement in connectionManagerDataSection.ConnectionManagerEndpoints) 6: { 7: var endpoint = new ConnectionManagerEndpoint() { Name = endpointElement.Name, ServerInfo = new ConnectionManagerServerInfo() { Address = endpointElement.Address, UseSSL = endpointElement.UseSSL, SecurityGroupsAllowedToSaveChanges = endpointElement.SecurityGroupsAllowedToSaveChanges.Split(',').Where(e => !string.IsNullOrWhiteSpace(e)).ToList() } }; 8: AddEndpoint(endpoint); 9: } 10: } This looks very similar to what we had before in the “simple” example.  The main points of interest are that we cast the section as ConnectionManagerDataSection (which is the class we defined for our section) and then iterate over the endpoints collection using the ConnectionManagerEndpoints property we created in the ConnectionManagerDataSection class.   Also, some other helpful resources around using app.config that I found (and for parts that I didn’t really explain in this article) are: How do you use sections in C# 4.0 app.config? (Stack Overflow) <== Shows how to use Section Groups as well, which is something that I did not cover here, but might be of interest to you. How to: Create Custom Configuration Sections Using Configuration Section (MSDN) ConfigurationSection Class (MSDN) ConfigurationCollectionAttribute Class (MSDN) ConfigurationElementCollection Class (MSDN)   I hope you find this helpful.  Feel free to leave a comment.  Happy Coding!

  • UTF-8 encoding problem with flash mysql and php

    - by alibhp
    Hi, As you may know, I am programming an on-line game using FLASH. I am connecting my FLASH 8 movie with MySQL database through PHP. I am doing very good in that, and I have everything working fine. The problems come when I am trying to insert (Using the INSERT SQL func) data to the database that are non-english. In other words, UTF-8 data. I red a lot of articls about that stuff and found and apply the fallowing: 1. In PHP4, you need to tell the PHP to use UTF-8 when using the xml_parser_crater() func, however, in PHP5 that is done automatically. Even though I told PHP5 to use the UTF-8 when calling the func. Adding the header to the XML sent to PHP from flash. Force the FLASH to use UTF-8 encoding in the preference options. Set the encoding in MySQL to UTF-8 (utf8_unicode_ci with InnoDB engine). I can read and insert the other language data correctly in the phpadmin as well. I did all that in my coding, and still I can't insert such data. one more strange thing is that, when I use the same link, that the FLASH using, with the XML, that the FLASH creating, on the browser (google chrome), I got the data inserted right in the database!!!!! I am about to get crazy about that stuff, What am I missing? what cause the problem? Thank you in advance.

  • Panning with the OpenGL Camera / View Matrix

    - by Pris
    I'm gonna try this again I've been trying to setup a simple camera class with OpenGL but I'm completely lost and I've made zero progress creating anything useful. I'm using modern OpenGL and the glm library for matrix math. To get the most basic thing I can think of down, I'd like to pan an arbitrarily positioned camera around. That means move it along its own Up and Side axes. Here's a picture of a randomly positioned camera looking at an object: It should be clear what the Up (Green) and Side (Red) vectors on the camera are. Even though the picture shows otherwise, assume that the Model matrix is just the identity matrix. Here's what I do to try and get it to work: Step 1: Create my View/Camera matrix (going to refer to it as the View matrix from now on) using glm::lookAt(). Step 2: Capture mouse X and Y positions. Step 3: Create a translation matrix mapping changes in the X mouse position to the camera's Side vector, and mapping changes in the Y mouse position to the camera's Up vector. I get the Side vector from the first column of the View matrix. I get the Up vector from the second column of the View matrix. Step 4: Apply the translation: viewMatrix = glm::translate(viewMatrix,translationVector); But this doesn't work. I see that the mouse movement is mapped to some kind of perpendicular axes, but they're definitely not moving as you'd expect with respect to the camera. Could someone please explain what I'm doing wrong and point me in the right direction with this camera stuff?

  • How to make a system time-zone sensitive?

    - by Jerry Dodge
    I need to implement time zones in a very large and old Delphi system, where there's a central SQL Server database and possibly hundreds of client installations around the world in different time zones. The application already interacts with the database by only using the date/time of the database server. So, all the time stamps saved in both the database and on the client machines are the date/time of the database server when it happened, never the time of the client machine. So, when a client is about to display the date/time of something (such as a transaction) which is coming from this database, it needs to show the date/time converted to the local time zone. This is where I get lost. I would naturally assume there should be something in SQL to recognize the time zone and convert a DateTime field dynamically. I'm not sure if such a thing exists though. If so, that would be perfect, but if not, I need to figure out another way. This Delphi system (multiple projects) utilizes the SQL Server database using ADO components, VCL data-aware controls, and QuickReports (using data sources). So, there's many places where the data goes directly from the database query to rendering on the screen, without any code to actually put this data on the screen. In the end, I need to know when and how should I get the properly converted time? There must be a standard method for this, and I'm hoping SQL Server 2008 R2 has this covered...

  • Magento - How to manage multiple base currencies and multiple payment gateways?

    - by Diego
    I have two requirements to satisfy, I hope someone with more experience can help me sorting them out. Multiple Base Currencies My client wants to allow visitors to place orders in whatever currency they prefer, choosing from the ones he’ll configure. Magento only supports one Base Currency, and this is, obviously, not what I need. I checked the solution involving multiple websites, but I need a customer to be registered once and stay on the same website, not to switch from one to the other and have to register/log in on each. Manage multiple Payment Gateways per currency and per payment method This is another crucial requirement, and it’s tied to the first one. My client wants to “route” payments in different currencies to different accounts. He’ll thus have one for Euro, one for USD and one for GBP. Whenever a customer pays with one of these currencies, the payment gateway has to be chosen accordingly. Additionally, the gateway should be different depending on other rules. For example, if customer pays with a Debit Card, my client will have a payment gateway configured especially for it. If customer pays with MasterCard, the gateway will be different, and so on. The complication, in this case, arises from the fact that my client uses Realex Payments and, although it would be possible for him to open multiple accounts, the Realex module expects one single gateway. In a normal scenario, we would need up to six instead: Payment with Debit Card in Euro Payment with Credit Card in Euro Payment with Debit Card in US Dollars Payment with Credit Card in US Dollars Payment with Debit Card in GB Pounds Payment with Credit Card in GB Pounds This, of course, if he doesn’t decide to accept other payment methods, such as bank transfer, which would add one more gateway per currency. Is there a way to achieve the above in Magento? I never had such complicated requirements before, and I’m a bit lost. Thanks in advance for the help.

  • Moving from windows to linux

    - by rincewind
    I need to reconcile these 2 facts: I don't feel comfortable working on Linux; I need to develop software for Linux. Some background: I have a 10+ years of programming experience on Windows (almost exclusively C/C++, but some .NET as well), I was a user of FreeBSD at home for about 3 years or so (then had to go back to Windows), and I've never had much luck with Linux. And now I have to develop software for Linux. I need a plan. On Windows, you can get away with just knowing a programming language, an API you're coding against, your IDE (VisualStudio) and some very basic tools for troubleshooting (Depends, ProcessExplorer, DebugView, WinDbg). Everything else comes naturally. On Linux, it's a very different story. How the hell would I know what DLL (sorry, Shared Object) would load, if I link to it from Firefox plugin? What's the Linux equivalent of inserting __asm int 3/DebugBreak() in the source and running the program, and then letting the OS call a debugger? Why the hell release builds use something, called appLoader, while debug builds work somehow different? Worst of all: how to provision Linux development environment? So, taking into account that hatred is usually associated with not knowing enough, what would you recommend? I'm ok with Emacs and GCC. I need to educate myself as a Linux admin/user, and I need to learn proper troubleshooting tools (strace is cool, btw), equivalents to the ones I mentioned above. Do I need to do Linux From Scratch? Or do I need to just read some books (I've read "UNIX programming enviornment" by Kernighan and "Advanced Programming..." by Stevens, but I need to learn something more practical)? Or do I need to have some Linux distro on my home computer?

  • Who would be the most efficacious Patron Saint of Programmers? [closed]

    - by Peter Turner
    The purpose of this question is to find someone out there to intercede for us and help our coding (not to magically align the bytes), to inspire our daily grind of software development by their lives of heroic virtue, to unite us under a common patron and to keep us on the straight and narrow path (i.e. don't be evil). In days of yore, the professional guilds had a patron saint. Regardless of whether we have a higher tendency to be atheists or not, who would you choose as the patron saint of programmers and what would be your criteria? Some people have chosen St. Isidore of Seville, but he's more like the patron saint of Wikipedia. If you're not Catholic please don't hesitate to nominate someone, just say what your criteria is. At the very least they should be dead and have lived a life of heroic virtue - or have died trying. It's a very pragmatic and noble custom which I heartily encourage. But if you find the practice off-putting, please don't be offended. I only mean to ask this question to other like minded programmers, which I have reason to believe exist. If you add a picture and a maybe make up a prayer that'd be excellent. It doesn't have to be gilded, illuminated and rhyme, although that would be sweet.

  • How do you prefer to handle image spriting in your web projects?

    - by Macy Abbey
    It seems like these days it is pretty much mandatory for web applications to sprite images if they want many images on their site AND a fast load time. (Spriting is the process of combining all images referenced from a style sheet into one/few image(s) with each reference containing a different background position.) I was wondering what method of implementing sprites you all prefer in your web applications, given that we are referring to non-dynamic images which are included/designed by the programming team and not images which are dynamically uploaded by a third party. 1. Add new images to an existing sprite by hand, create new css reference by hand. 2. Generate a sprite server-side from your css files which all reference single images set to be background images of an html element that is the same size of the image you are spriting once per build and update all css references programmatically. 3. Use a sprite generating program to generate a sprite image for you once per release and hand insert the new css class / image into your project. 4. Other methods? I prefer two as it requires very little hand-coding and image editing.

  • Advices fo starting a video game design career

    - by Allen Gabriel Baker
    I'm 24 and have a passion for video games and game-design. I've decided I want to design video games as my career. I have no experience with designing video games or coding but I'm interested and willing to learn. I want a job at any level but what would I need to land a job? I have no college experience and I have no money. What is a cheap school, or do I really need to go to school for this, or can I learn on my own? Is it possible to do this with no money? I'm literally broke but I want this so bad I feel like its the only career I'll enjoy. I want to call up company's and ask them what they are looking for in someone they want to hire, is that a good idea? Also I don't know the history of video game design and I don't want to sound like a dummy when someone says something about this field or talks about a famous designer and I have no idea who they're talking about. So what is key info when it comes to this field and where should I find it? Hopefully some of you guys and girls can help me out: I know in the future I will create something everyone will enjoy and you guys will remember when you gave me advice and I will always remember you guys for helping me. I'm gifted I know I am and I want to share my gift with the rest of the world by making games that change the Industry. Help me out please.
