• 3d js map rendering

  - by gotha

  In the past I've done a 2D tile map using HTML, CSS and Javascript. Now I have the task of creating a 3D version using the same technologies - think of it like a space map where all planets have x/y/z positions. Currently, I have no idea to do this. Is there an existing library or something I can modify to do my job? If not, what method of rendering the map should I use? It needs to be as browser independent as possible, so I can't use webgl, flash or canvas. I'm considering plain JS & HTML or SVG (using Raphael for compatibility).

• Removing unnecessary joomla CMS components

  - by Gaz_Edge

  Background I have been developing a web application. I have been using Joomla platform and CMS as the base from my application. My application relies heavily on the joomla platform, but uses very few features of the CMS (I have to login users etc so I use the _users component of the CMS). Question What is the best way to start removing some of the excess CMS that I don't need? For example when I being building my production site, I will want to avoid creating a load of joomla component database tables etc. I have read that an application can be build from the ground up using just the joomla platform, but i still want to include the _users component and would also like to avoid having to start coding all the session handling aspects. Any advice?

• ASP.NET RedirectPermanent Method using C# and VB.NET

  301 redirection is essential for the best user experience. If something on your website has been changed or moved to a new permanent location, users will need to be permanently redirected. In addition, search engines can follow this type of redirection, and this redirected-to page will now be the one to rank in Google or other search engines, replacing the old page. There are different ways to implement the RedirectPermanent method. This tutorial will illustrate these common techniques with sample VB.NET or C# code. Creating the Sample ASP.NET 4.0 Website RedirectPermanent is new in ASP.NET 4....

• Using a Higher Precision (than 8-bit unsigned integer) Buffered Image for Heightmaps in Java

  - by pl12

  I am generating a heightmap for every quad in my quadtree in openCL. The way I was creating the image is as follows: DataBufferInt dataBuffer = (DataBufferInt)img.getRaster().getDataBuffer(); int data[] = dataBuffer.getData(); //img is a bufferedimage inputImageMem = CL.clCreateImage2D( context, CL_MEM_READ_WRITE | CL_MEM_USE_HOST_PTR, new cl_image_format[]{imageFormat}, size, size, size * Sizeof.cl_uint, Pointer.to(data), null); This works ok but the major issue is that as the quads get smaller and smaller the 8-bit format of the buffered image starts to cause intolerable "stepping" issues as seen below: I was wondering if there was an alternate way I could go about doing this? Thanks for the time.

• Faking Display tree (Sprite) parent child relationships with rasters (BitmapData) in ActionScript 3

  - by Arthur Wulf White

  I am working with Rasters (bitmapData) and blliting (copypixels) in a 2d-game in actionscript 3. I like how you can move a sprite and it moves all it's children, and you can simultaneously move the children creating an interesting visual effect. I do not want to use rotation or scaling however cause I do not know how that can be done without hampering with performance. So I'm not simulating Sprite parent-child behavior and sticking to the movement on the (x, y) axis. What I am planning to do is create a class called RasterContainer which extends bitmapData that has a vector of children of type Raster(extending bitmapData), now I am planning to implement recursive rendering in RasterContainer, that basically copyPixels every child, only changing their (x, y) offset to reflect their parent's offset. My question is, has this been implemented in an existing framework? Is this a good plan? Do I expect a serious performance hit for using recursive methods this way?

• Preseed Ubuntu installation with full disk encryption

  - by user249264

  I am trying to set up Ubuntu full disk encryption using preseeding. I was able to set things up correctly following the preseed file presented here. But I do not want to provide the default password in the preseed file. Is there a way to let ubiquity fall to the screen that asks for the encryption passphrase just like it does when the username is not provided in the preseed file? When I try to leave the passphrase option empty in the preseed file, I get an error in the installer saying "An error occured while creating the keyfile".

  - by marcamillion

  If I am not storing credit card info, do I have to be concerned with PCI-compliance? I will be using a payment processor with a bank in my country.

• Get script for every action in SQL Server Management Studio

  I am always conscious to keep a record of all operations performed on my database servers. Operations through T-SQL in an SSMS query pane can easily be saved in query files. For table modifications through SSMS designer I have predefined setting to generate T-SQL scripts. However there are numerous database and server level tasks that I use the SSMS GUI and I would like to have a script of these changes for later reference. Examples of such actions through the SSMS GUI are backup/restore, changing compatibility level of a database, manipulating permissions, dealing with database or log files or creating/manipulating any login/user. I am looking for any way to generate T-SQL code for such actions, so that it may be kept for later reference

• How to achieve 'forward' movement (into the screen) using Cocos2D?

  - by lemikegao

  I'm interested in creating a 2.5D first-person shooter (like Doom) and I currently don't understand how to implement the player moving forward. The player will also be able to browse around the world (left, right, up, down) via gyroscope control. I plan to only use 2D sprites and no 3D models. My first attempt was to increase the scale of layers to make it appear as if the player was moving toward the objects but I'm not sure how to make it seem as if the player is passing around the objects (instead of running into them). If there are extensions that I should take a look at (like Cocos3D), please let me know. Thanks for the help! Note: I've only created 2D games so was hoping to get guided into the right direction

• Database Development and Source Control

  - by Enrique Lima

  I have been working with Database Development and the aspects that come with it, the pain and the joy of moving from Dev to QA and then on to Production.  Source Control has a place in Dev, and that is where the baselines should be established. Where am I going with this? I have been working with Redgate’s Source Control 3.0, and I am seeing some features that are great for the process of moving from Dev to … well something that allows for quite a level of control.  We are not only talking about scripting the structure of a database, but creating a baseline, working with migration scripts, and integrated with Redgate’s Schema Compare.  There is a detailed paper that will be posted here in the next day or so to provide step by step information of the process to define your baseline in Dev and then take it to the desired destination. In the meantime, check the Webinars Redgate has regarding this process and products.

• How does Against The Wall create an infinite wall?

  - by Zolani13

  There is a game called Against The Wall, developed by Michael P. Consoli. It's a fantastic game, as I've always been stumped at how the game creates an infinitely spanning wall. In the game, you can fall forever, and the wall will keep spanning. I can fall as long as I like, and still be able to climb back to where I was before. The game is developed in Unity. How can a game do this without crashing, or creating some kind of memory overload?

• Data structures for storing finger/stylus movements in drawing application?

  - by mattja?øb

  I have a general question about creating a drawing application, the language could be C++ or ObjectiveC with OpenGL. I would like to hear what are the best methods and practices for storing strokes data. Think of the many iPad apps that allow you to draw with your finger (or a stylus) or any other similar function on a desktop app. To summarize, the data structure must: be highly responsive to the movement store precise values (close in space / time) usable for rendering the strokes with complex textures (textures based on the dynamic of the stroke etc) exportable to a text file for saving/loading

• How to use auto login in a remastered LiveCD?

  - by Jayo

  I have been creating a custom live CD of Ubuntu 11.10 using remastersys, everything goes well except that the live session asks for a login. the login is automatically set as "custom" and the password is blank. this is fine, but I would rather it went direct to the desktop in a live session as you would expect from other distro live cds. I have asked on the remastersys forums, the question has gotten a lot of views, but no answer as of yet, I am wondering has anyone here remastered a distro and come across the login problem, and if so, how did you fix it?

• How Would You Design This Table?

  - by sooprise

  I have to create a table where each row needs to store 50 number values. Each row will always need to store 50 number values. If this was a smaller number of values, I would just make fields for each of the values, but because there are 50, this approach seems a bit cumbersome (but since it will always be 50 values, maybe this is the correct approach?). Is there a way to store an array of values in a field? This seems like a nice solution, but the concept is almost identical to creating a relational database.

• Shut down Netbook by closing lid - ubunti 13.10

  - by The Liquidator

  My wife has an Acer Aspire One (with the SSD Card and an SD expansion card). It has never been able to hibernate or suspend, always creating errors and occasionally trashing the data on the SD card, which is the home partition so it's unfortunate. To get around the problem I have set all exit methods to produce shutdown - she tends to simply shut the lid. I'm aware the default behaviour has for some time been to suspend, but I've got round that using the gnome tweak tool. However, I've just installed 13.10 and whilst I have installed the gnome tweak tool and set it to shut down the system appears to be ignoring/bypassing the setting, electing to suspend when the lid is shut. Can anyone tell me how to fix it please? I'm quite happy to get my hands dirty with the command line.

• schema.org specification for generic pages or posts on a CMS

  - by NateWr

  I'm trying to determine the best possible schema.org type to declare for the content section in the template of a content management system, which will handle regular news posts for small, local hospitality businesses. The type should represent the content of that page, which is likely to be a wide range of things. The description for Article pretty strongly encourages its use to be limited to the articles of a publication. For purely semantic reasons, I'm not sure if Blog is appropriate in this case -- businesses won't be creating typical "blog" content but are more likely to be writing about upcoming events, special deals, awards, etc. Would Webpage be appropriate in this instance? Although I'm a fan of the schema.org concept, I frequently find myself unsure how broadly or narrowly I'm meant to infer the meaning of a type. In such cases, is it safe to use a high-level element, such as CreativeWork, or does this blunt the usefulness of the markup?

• Game Asset Storage: Archive vs Individual files

  - by David Colson

  As I am in the process of creating a 3D c++ game and I was wondering what would be more beneficial when dealing with game assets with regards to storage. I have seen some games have a single asset file compressed with everything in it and other with lots of little compressed files. If I had lots of individual files I would not need to load a large file at once and use up memory but the code would have to go about file seeking when the level loads to find all the correct files needed. There is no file seeking needed when dealing with one large file, but again, what about all the assets not currently needed that would get loaded with the one file? I could also have an asset file for each level, but then how do I deal with shared assets This has been bothering me for a while so tell me what other advantages and disadvantages are there to either way of doing things.

• If a company is using ubuntu on its servers/dektops, does it have to pay?

  - by rsjethani

  a friend of my friend has started a small firm and given me the responsibility to erect all the IT infrastructure required? I'm basically a windows guy that too on the developer side. But recently I fell in love with Linux n dared to dream about becoming a Linux admin and play with Linux, virtualization, cloud etc. So, first I'll be running a pilot project of creating mail/ftp/web servers required on a Linux based server. And Ubuntu is the ideal choice for a Linux beginner right? my question is simple: if a commercial organization is using Ubuntu for it's day to day desktop and server(mail,ftp etc) uses but has technicians which can provide support internally then do the organization needs to pay for Ubuntu? If yes then could you please suggest a Debian based distro on the lines of CentOS. Also can I use the Ubuntu 12.04 LTS 64 bit desktop version instead of the no gui server version for the server machine(gui can be helpful for a windows guy like me) thanks.

• How do I create a WiFi hotspot sharing wireless internet connection (single adapter)?

  - by Ruppesh Nalwaya

  I know how to create a hotspot when connected to a wired network, but when I am using internet from a WiFi connection, this disconnects the wireless connection the moment I activate the hotspot. In Windows I can use Connectify Hotspot, which enables me to share the internet connection from the same wireless adapter as I am creating an access point on. As you can read on the technology overview page: Access Point mode allows you to create a hotspot using the same Wi-Fi card that you are using to access the Internet. How do I do this on Ubuntu?
