• Realistic planetary terrain generation with weights

  - by Programmdude

  I need terrain generation for a planet. The planet will be divided up into several hundred hexes, and I need it to be realistic and based on weights. I have dabbled in terrain generation before, but nothing like this. So I figure it would be a good idea to ask the community for answers, recommended articles or the like. By realistic, I mean not just random hexes, but continent shaped things with a few islands. More desert around the equator and more ice around the poles. I also have two weights I need to base it around: ice percentage and water percentage. That means that around XX% of the planet will need to be water. Does anyone have any advice or places to start? Generating arbitrary terrain is easy, but something a bit more "organic" like this seems rather difficult. It also needs to be seamless. Should be obvious since it's a planet, but no harm in pointing it out.

• Align tetrahedrons

  - by thedeadlybutter

  I'm currently generating tetrahedron meshes in Unity When a player clicks the side of a mesh, a new one spawns aligned with it, like this. I'm not sure how nor can I find any information on implementing a tetra hedron grid. I tried playing around with the vertices until I realized I need to adjust position & rotation. Any ideas? EDIT: To be clear, the second image was manually placed objects in the Unity Editor. I'm looking to make an algorithm that places the meshes correctly.

• Android: debug certificate expired error

  - by Bill Osuch

  I started up Eclipse today, created a new project, and immediately had an error before I had changed a single line: Error generating final archive: Debug Certificate expired on 11/12/11 When installed, the Android SDK generates a "debug" signing certificate for you in a file called "debug.keystore". Eclipse uses this certificate rather than forcing you to create a new one for every project. In older versions of Eclipse, the certificate was only valid for 365 days, but as I understand it the default has been changed to 30 years in newer versions. If for whatever reason you don't want to upgrade Eclipse, you can manually delete the certificate to for Eclipse to generate a new one. You can find the location in Preferences -> Android -> Build -> Default debug keystore (mine was in C:\Users\myUserName\.android\); just delete the "debug.keystore" file, then go back into Eclipse and Clean the project to generate a new file.

• Is there a way to procedurally generate the history of a world?

  - by pdusen

  I am somewhat intrigued by the diagram found here representing 1800 years of cultural history in an imaginary world some guy created. This sort of thing would seem to have strong applications for game development, insofar as world design. It looks like he did this diagram by hand. What I'm interested in is seeing if there is a way to create this sort of diagram programatically. If you were tasked with generating diagrams in the style of the above from random values, how would you go about it? Are there any particular data structures or algorithms that you would consider?

  Whoa, cool! Forbes magazine has an online article about what I've been blogging about all this time: Big Data and Java Embedded Technology, tying it all together with a big bow, connecting small devices to the data center. See: Billions of Java Embedded Devices Here's a quote: By the end of the decade we could see tens of billions of new Internet-connected devices... with billions of Internet- connected devices generating Big Data, are the next big thing. ... That’s why Oracle has put together an ecosystem of solutions for this new, Big Data-oriented device-to-data center world: secure, powerful, and adaptable embedded Java for intelligent devices, integrated middleware...

• Motivating developers in a project perceived as **dull** ?

  - by Fanatic23

  As a manager, I can't always end up generating work that'd be cutting edge. Some of the projects do run on maintenance mode, and generate a healthy free cash flow for the company. As a developer what would it take for you to stick around in this project? I have been thinking of re-branding the work, but I could do with a lot of help here. Appreciate a single response per post. Please don't suggest an increased pay-packet, this creates more problems than it solves.

• Upgrading visual studio with Crystal Reports

  - by jkrebsbach

  In the process up updating an app from Visual Studio 2003 to VS 2008.  It happens to have a couple dozen crystal reports that it executes regarly. Upgraded visual studio to 2008, and when attempting to generate the reports an exception was thrown. A significant portion of the rendering engine for Crystal Reports is not coming from Crystal, it's coming from Visual Studio and those methods and properties have changed over the years.  I needed to upgrade the report generating methods from the VS 2003 way of doing things to the VS 2008 way for the report to generate successfully. Not only that, but this means that while we were previously rendering with Crystal 9 in VS 2003, Visual Studio 2008 will render per Crystal 10, which treats things like column widths in Excel different (by default, at least) so now we have to go through all of our reports and compare outputs for Crystal just to upgrade the Visual Studio environment that I foolishly believed would  not be affected.

• Documenting a REST interface with a flowchart

  - by James Kassemi

  Does anybody have suggestions on creating a flowchart representation of a REST-style web interface? In the interest of supplying thorough documentation to co-developers, I've been toying around in dia modeling the interface for modifying and generating a product resource: This particular system begins to act differently with user authentication/resource counts, so before I make modifications, I'm looking for some clarification: Complexity: how would you simplify the overall structure to make this easier to read? Display Symbol: is this appropriate for representing a page? Manual Operation Symbol: is this appropriate for representing a user action like a button click? Any other suggestions would be greatly appreciated. My apologies for the re-post. The main stackexchange site suggested this question was better presented on programmers.

• Will Traffic exchange programs work in Pay per impression ad campaigns

  - by vinoth

  I'm having a technology blog with nearly 3000 visitors a day (1000 - 1300 unique visitors). I'm generating visitors through traffic exchange programs like hitleap.com, addmefast.com. Now i'm planning to go with some pay per impression programs. So far i came to know that google adsense won't allow using traffic exchange programs. Did all pay-per-impression programs will follow the same ? will i get banned using traffic exchange programs? Please reply me your suggestions, Thanks in advance. Sorry for my bad English.

• Placeholder images for testing reports

  - by Greg Low

  Lorem Ipsum has long been used to provide placeholder text for testing report and document layouts. Programs such as Microsoft Word have also included options for generating sample text. (For example, type =rand() anywhere in a blank area of a Microsoft Word document and hit enter).Matthew Roche and Donald Farmer both sent me a link the other day to an online service that provides placeholder images. This could be quite useful when testing report layouts in SQL Server Reporting Services.You'll find it here: http://lorempixel.com/Nice! As an example, here's a random sports image. Of course I have no idea what you'll see on this page :-)

• ways to program glitch style effects

  - by okkk

  Most tutorials for generating glitch art usually has to do with some form of manipulation of the compression of files. Should my goal instead to replicate the look of these glitches in shaders or is it somehow possible to authentically generate the compression artifacts in real time? Example: This effect which I'm particularly interested is referred to as datamoshing. It does "things" using the p-frames of a video (frames that I think store just the change in pixels). I feel like I need a better understanding of both graphics programming and data-compression.

• How well do free-to-open-source-projects policies work in practice?

  - by Steve314

  In comparison with an open source license and requesting donations, is a free-for-open-source-projects (or free for non-commercial developers) closed source and otherwise commercial project likely to get more license fees? Or just to alienate potential users? Assume the project has value to programmers - I'm looking for generalizations here, though specific examples comparing existing projects will be very interesting. What I have in mind involves code generating programming utilities. And one issue I can think of, either way, is a near total inability to enforce any license restrictions. After all, I can't go around the internet demanding that everyone show me their source code just in case!

• Create an Asynchronous JAX-WS Web Service and call it from Oracle BPEL 11g

  - by Bob Webster

  This posting is the result of a simple requirement to take an existing JAX-WS Web service,convert it to be asynchronous and call it from Oracle BPEL 11g It turned out that this is not a trivial task... BPEL has some very specific expectations about the WSDL for an asynchronous process. One approach is to develop the service starting from a WSDL document that meets BPEL's requirements. This is possible but requires considerable WSDL authoring skills. The other approach is to modify the WSDL generated by Web Service Annotations in Java code (Bottom up development) and instruct JAX-WS to use that WSDL instead of dynamically generating one from annotations. This is the approach taken in this article. This posting details how to: Modify a JAX-WS Web Service developed using a "Bottom up " approach to have an asynchronous method and callback. Call the Asynchronous Service from Oracle BPEL 11g. Read the full posting here.

• webmaster tools 500 crawl error for asp faceted navigation that does not exist

  - by user19007

  i am getting 2,500 type 500 url errors in google webmaster tools. These pages are faceted navigation results that can not be reached by a site visitor. These pages do not exist. We are using faceted navigation with the Volusion platform (asp.net, I think). I have specified url parameters in webmaster tools so that google will not try to index anything faceted. This does not stop the errors from generating. I am concerned about how this might effect seo (bleeding page rank). I can provide additional information if needed. I am not sure how to solve this. I have started down the path of creating 301's, but having some difficulty there as well.

• would a composite design pattern be useful for group membership?

  - by changokun

  I'm trying to think about the best way to handle group memberships on a website. People sign up and select checkboxes in a list of interests. Every week we send out interest-themed emails to those members that indicated that interest. however i store the information in the database, while i am working with the lists and generating lists of email addresses or manipulating group memberships, the composite design pattern looked interesting. it would be easy to populate the group, then do some aggregating functions that say... generate the list of email addresses based on the interests. but i'm not sure i'm seeing any other advantages. i do need something scalable, and flexible. thoughts?

• Should you salary reflect how much work there is for you or does that not matter? [closed]

  - by Kevin Simper

  I am working in a consulting company, where the company mostly do IT support. The website is also only focused on IT support, and we do not therefore capture leads for the Web Department. We aim for Small busniess, which needs new computers and firewalls. We were having a performance conversation and talked about salary and my employer told that he was not impressed by the revenue I was generating. I told that I did not have enough work and I would like to get more tasks and project so that i could reach the goal, but that i did not think it was my fault that there was not enough work. He said that it was not his fault either, but he could not pay me more. Is he right that I should not get paid more just because my employee can not get enough Web projects, or should i be paid what i am worth not based on the work amount the sales generate?

• Procedural Planets, Heightmaps and Textures

  - by henryprescott

  I am currently working on an OpenGL procedural planet generator. I hope to use it for a space RPG, that will not allow players to go down to the surface of a planet so I have ignored anything ROAM related. At the moment I am drawing a cube with VBOs and mapping onto a sphere. I am familiar with most fractal heightmap generating techniques and have already implemented my own version of midpoint displacement (not that useful in this case I know). My question is, what is the best way to procedurally generate the heightmap. I have looked at libnoise which allows me to make tilable heightmaps/textures, but as far as I can see I would need to generate a net like this. Leaving the tiling obvious. Could anyone advise me on the best route to take? Any input would be much appreciated.

• How can I store all my level data in a single file instead of spread out over many files?

  - by Jon

  I am currently generating my level data, and saving to disk to ensure that any modifications done to the level are saved. I am storing "chunks" of 2048x2048 pixels into a file. Whenever the player moves over a section that doesn't have a file associated with the position, a new file is created. This works great, and is very fast. My issue, is that as you are playing the file count gets larger and larger. I'm wondering what are techniques that can be used to alleviate the file count, without taking a performance hit. I am interested in how you would store/seek/update this data in a single file instead of multiple files efficiently.

• How do I get Catalyst 11.10 with ATI Radeon Mobility HD 5470 working on an HP DV7?

  - by S Kumar

  I have a HP DV7 with a HD 5470 512M card. Installation of the Catalyst 11.10 is repeatedly failing on a fresh install of Ubuntu 11.10. Catalyst 11.8 proprietary drivers were working well with Ubuntu 11.04. I have tried installing directly from the .run and generating the distribution specific packages. Nothing has worked. After installation which goes through successfully, the system hangs on reboot after the flashing dots. I have to replace the /etc/X11/xorg.conf to get the X working. I have followed instructions as per the http://wiki.cchtml.com/index.php/Main_Page wiki. Request for support to ATI/AMD gives the response that this model is unsupported on Linux by HP :). Updated 14-Nov I have reverted back to the open source drivers which work well enough for me.
