  • Simple Java networking game engine [on hold]

    - by Florian Peschka
    I want to create a simple java networking game and search a networking engine that eases use of sockets etc. I have already read some questions on here and the internet about java networking for games, but many of them were over 10 years old or not really answered. I have no idea whatsoever about what exactly I need to send in terms of messages, but I figured simple strings or integers will be enough for my purposes. It's basically a peer to peer game, so I don't need a centralized server structure. Messaging doesn't have to have an extremely low ping, yet of course all players need to have a synchronized view. What are the possibilities I have here?

  • When should JavaScript generate HTML?

    - by VirtuosiMedia
    I try to generate as little HTML from JavaScript as possible. Instead, I prefer to manipulate existing markup whenever I can and only generate HTML when I need to dynamically insert an element that isn't a good candidate for using Ajax. This, I believe, makes it far easier to maintain the code and quickly make changes to it because the markup is easier to read and trace. My rule of thumb is: HTML is for document structure, CSS is for presentation, JavaScript is for behavior. However, I've seen a lot of JS code that generates mounds of HTML, including entire forms and content-heavy modal dialogs. In general, which method is considered best practice? In what circumstances should JavaScript be used to generate HTML and when should it not?

  • Migrate add-on domain olddomain.com to newdomain.com

    - by eHx
    I have 2 domains that are registered at GoDaddy : domaina.com (not hosted, only domain name is registered to GD) domainb.com (hosted at a different webhost, domain name registered to GD) domainb.com is an already working site, with a different webhost, but the domain name is registered to GoDaddy(and I assume the nameservers are changed to redirect to the webhost). Now, I don't understand why this was done, but domainb.com is considered a subdomain on the host... meaning the files are in a seperate folder on the server. Ex : public-html/domainb.com/public-html/FILES The structure is similar to this on the webhost : HostNAME (main root folder) domainb.com (subdomain of hostname) domainc.com (etc...) domaind.com (etc...) I want to transfer the site domainb.com to domaina.com, meaning domaina.com will become the new website, without having to re-upload all the content and CMS. The old one will redirect to domaina.com once the transfer is done (using 301 redirects). Can anyone tell me how I can do this?

  • RIDC Accelerator for Portal

    - by Stefan Krantz
    What is RIDC?Remote IntraDoc Client is a Java enabled API that leverages simple transportation protocols like Socket, HTTP and JAX/WS to execute content service operations in WebCenter Content Server. Each operation by design in the Content Server will execute stateless and return a complete result of the request. Each request object simply specifies the in a Map format (key and value pairs) what service to call and what parameters settings to apply. The result responded with will be built on the same Map format (key and value pairs). The possibilities with RIDC is endless since you can consume any available service (even custom made ones), RIDC can be executed from any Java SE application that has any WebCenter Content Services needs. WebCenter Portal and the example Accelerator RIDC adapter frameworkWebCenter Portal currently integrates and leverages WebCenter Content Services to enable available use cases in the portal today, like Content Presenter and Doc Lib. However the current use cases only covers few of the scenarios that the Content Server has to offer, in addition to the existing use cases it is not rare that the customer requirements requires additional steps and functionality that is provided by WebCenter Content but not part of the use cases from the WebCenter Portal.The good news to this is RIDC, the second good news is that WebCenter Portal already leverages the RIDC and has a connection management framework in place. The million dollar question here is how can I leverage this infrastructure for my custom use cases. Oracle A-Team has during its interactions produced a accelerator adapter framework that will reuse and leverage the existing connections provisioned in the webcenter portal application (works for WebCenter Spaces as well), as well as a very comprehensive design patter to minimize the work involved when exposing functionality. Let me introduce the RIDCCommon framework for accelerating WebCenter Content consumption from WebCenter Portal including Spaces. How do I get started?Through a few easy steps you will be on your way, Extract the zip file RIDCCommon.zip to the WebCenter Portal Application file structure (PortalApp) Open you Portal Application in JDeveloper (PS4/PS5) select to open the project in your application - this will add the project as a member of the application Update the Portal project dependencies to include the new RIDCCommon project Make sure that you WebCenter Content Server connection is marked as primary (a checkbox at the top of the connection properties form) You should by this stage have a similar structure in your JDeveloper Application Project Portal Project PortalWebAssets Project RIDCCommon Since the API is coming with some example operations that has already been exposed as DataControl actions, if you open Data Controls accordion you should see following: How do I implement my own operation? Create a new Java Class in for example com.oracle.ateam.portal.ridc.operation call it (GetDocInfoOperation) Extend the abstract class com.oracle.ateam.portal.ridc.operation.RIDCAbstractOperation and implement the interface com.oracle.ateam.portal.ridc.operation.IRIDCOperation The only method you actually are required to implement is execute(RIDCManager, IdcClient, IdcContext) The best practice to set object references for the operation is through the Constructor, example below public GetDocInfoOperation(String dDocName)By leveraging the constructor you can easily force the implementing class to pass right information, you can also overload the Constructor with more or less parameters as required Implement the execute method, the work you supposed to execute here is creating a new request binder and retrieve a response binder with the information in the request binder.In this case the dDocName for which we want the DocInfo Secondly you have to process the response binder by extracting the information you need from the request and restore this information in a simple POJO Java BeanIn the example below we do this in private void processResult(DataBinder responseData) - the new SearchDataObject is a Member of the GetDocInfoOperation so we can return this from a access method. Since the RIDCCommon API leverage template pattern for the operations you are now required to add a method that will enable access to the result after the execution of the operationIn the example below we added the method public SearchDataObject getDataObject() - this method returns the pre processed SearchDataObject from the execute method  This is it, as you can see on the code below you do not need more than 32 lines of very simple code 1: public class GetDocInfoOperation extends RIDCAbstractOperation implements IRIDCOperation { 2: private static final String DOC_INFO_BY_NAME = "DOC_INFO_BY_NAME"; 3: private String dDocName = null; 4: private SearchDataObject sdo = null; 5: 6: public GetDocInfoOperation(String dDocName) { 7: super(); 8: this.dDocName = dDocName; 9: } 10:   11: public boolean execute(RIDCManager manager, IdcClient client, 12: IdcContext userContext) throws Exception { 13: DataBinder dataBinder = createNewRequestBinder(DOC_INFO_BY_NAME); 14: dataBinder.putLocal(DocumentAttributeDef.NAME.getName(), dDocName); 15: 16: DataBinder responseData = getResponseBinder(dataBinder); 17: processResult(responseData); 18: return true; 19: } 20: 21: private void processResult(DataBinder responseData) { 22: DataResultSet rs = responseData.getResultSet("DOC_INFO"); 23: for(DataObject dobj : rs.getRows()) { 24: this.sdo = new SearchDataObject(dobj); 25: } 26: super.setMessage(responseData.getLocal(ATTR_MESSAGE)); 27: } 28: 29: public SearchDataObject getDataObject() { 30: return this.sdo; 31: } 32: } How do I execute my operation? In the previous section we described how to create a operation, so by now you should be ready to execute the operation Step one either add a method to the class  com.oracle.ateam.portal.datacontrol.ContentServicesDC or a class of your own choiceRemember the RIDCManager is a very light object and can be created where needed Create a method signature look like this public SearchDataObject getDocInfo(String dDocName) throws Exception In the method body - create a new instance of GetDocInfoOperation and meet the constructor requirements by passing the dDocNameGetDocInfoOperation docInfo = new GetDocInfoOperation(dDocName) Execute the operation via the RIDCManager instance rMgr.executeOperation(docInfo) Return the result by accessing it from the executed operationreturn docInfo.getDataObject() 1: private RIDCManager rMgr = null; 2: private String lastOperationMessage = null; 3:   4: public ContentServicesDC() { 5: super(); 6: this.rMgr = new RIDCManager(); 7: } 8: .... 9: public SearchDataObject getDocInfo(String dDocName) throws Exception { 10: GetDocInfoOperation docInfo = new GetDocInfoOperation(dDocName); 11: boolean boolVal = rMgr.executeOperation(docInfo); 12: lastOperationMessage = docInfo.getMessage(); 13: return docInfo.getDataObject(); 14: }   Get the binaries! The enclosed code in a example that can be used as a reference on how to consume and leverage similar use cases, user has to guarantee appropriate quality and support.  Download link: https://blogs.oracle.com/ATEAM_WEBCENTER/resource/stefan.krantz/RIDCCommon.zip RIDC API Referencehttp://docs.oracle.com/cd/E23943_01/apirefs.1111/e17274/toc.htm

  • Google crawled all our RSS links - how do I remove these from their index? [closed]

    - by ElHaix
    Possible Duplicate: How to Remove URLs from Google Search Engine We added a RSS link to our site for our content. Since then, our site visits have diminished. If a user is viewing the RSS feed, the link itself does not go to the actual article/content. Instead, each link goes to a main index - where the content may have changed, and the article they clicked on COULD be on that page, depending on its age. The RSS link structure is as follows: www.oursite.com/[search term]/rsslink/[title of the rss link they clicked on] I'm not trying to do anything black-hat here, but wondering if we're getting penalized for this somehow. If this is the case, could I do something like permanently-removed on all /rsslink/ pages?

  • SQL SERVER – Weekly Series – Memory Lane – #005

    - by pinaldave
    Here is the list of curetted articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2006 SQL SERVER – Cursor to Kill All Process in Database I indeed wrote this cursor and when I often look back, I wonder how naive I was to write this. The reason for writing this cursor was to free up my database from any existing connection so I can do database operation. This worked fine but there can be a potentially big issue if there was any important transaction was killed by this process. There is another way to to achieve the same thing where we can use ALTER syntax to take database in single user mode. Read more about that over here and here. 2007 Rules of Third Normal Form and Normalization Advantage – 3NF The rules of 3NF are mentioned here Make a separate table for each set of related attributes, and give each table a primary key. If an attribute depends on only part of a multi-valued key, remove it to a separate table If attributes do not contribute to a description of the key, remove them to a separate table. Correct Syntax for Stored Procedure SP Sometime a simple question is the most important question. I often see in industry incorrectly written Stored Procedure. Few writes code after the most outer BEGIN…END and few writes code after the GO Statement. In this brief blog post, I have attempted to explain the same. 2008 Switch Between Result Pan and Query Pan – SQL Shortcut Many times when I am writing query I have to scroll the result displayed in the result set. Most of the developer uses the mouse to switch between and Query Pane and Result Pane. There are few developers who are crazy about Keyboard shortcuts. F6 is the keyword which can be used to switch between query pane and tabs of the result pane. Interesting Observation – Use of Index and Execution Plan Query Optimization is a complex game and it has its own rules. From the example in the article we have discovered that Query Optimizer does not use clustered index to retrieve data, sometime non clustered index provides optimal performance for retrieving Primary Key. When all the rows and columns are selected Primary Key should be used to select data as it provides optimal performance. 2009 Interesting Observation – TOP 100 PERCENT and ORDER BY If you pull up any application or system where there are more than 100 SQL Server Views are created – I am very confident that at one or two places you will notice the scenario wherein View the ORDER BY clause is used with TOP 100 PERCENT. SQL Server 2008 VIEW with ORDER BY clause does not throw an error; moreover, it does not acknowledge the presence of it as well. In this article we have taken three perfect examples and demonstrated which clause we should use when. Comma Separated Values (CSV) from Table Column A Very common question – How to create comma separated values from a table in the database? The answer is also very common if we use XML. Check out this article for quick learning on the same subject. Azure Start Guide – Step by Step Installation Guide Though Azure portal has changed a quite bit since I wrote this article, the concept used in this article are not old. They are still valid and many of the functions are still working as mentioned in the article. I believe this one article will put you on the track to use Azure! Size of Index Table for Each Index – Solution Earlier I have posted a small question on this blog and requested help from readers to participate here and provide a solution. The puzzle was to write a query that will return the size for each index that is on any particular table. We need a query that will return an additional column in the above listed query and it should contain the size of the index. This article presents two of the best solutions from the puzzle. 2010 Well, this week in 2010 was the week of puzzles as I posted three interesting puzzles. Till today I am noticing pretty good interesting in the puzzles. They are tricky but for sure brings a great value if you are a database developer for a long time. I suggest you go over this puzzles and their answers. Did you really know all of the answers? I am confident that reading following three blog post will for sure help you enhance the experience with T-SQL. SQL SERVER – Challenge – Puzzle – Usage of FAST Hint SQL SERVER – Puzzle – Challenge – Error While Converting Money to Decimal SQL SERVER – Challenge – Puzzle – Why does RIGHT JOIN Exists 2011 DVM sys.dm_os_sys_info Column Name Changed in SQL Server 2012 Have you ever faced a situation where something does not work? When you try to fix it - you enjoy fixing it and started to appreciate the breaking changes. Well, this was exactly I felt yesterday. Before I begin my story, I want to candidly state that I do not encourage anybody to use * in the SELECT statement. Now the disclaimer is over – I suggest you read the original story – you will love it! Get Directory Structure using Extended Stored Procedure xp_dirtree Here is the question to you – why would you do something in SQL Server where you can do the same task in command prompt much easily. Well, the answer is sometime there are real use cases when we have to do such thing. This is a similar example where I have demonstrated how in SQL Server 2012 we can use extended stored procedure to retrieve directory structure.

  • Devfish Joe Healy in Fort Lauderdale - Cloud Computing and Azure - 03/11/2010 MSDN Tiki Hut

    - by Rainer
    Devfish Joe Healy, Brian Hitney, and Herve Rogero presented excellent sessions on today's MSDN Tiki Hut Event about  Cloud Computing and Azure. This was an developer focused event, starting out with an overview about structure and platform, followed by working code samples running on the platform, and all needed information to get developers started on development for cloud applications. Participants had Q&A opportunities after each session and made good use of it. I am sure that a lot of developers will jump on the Azure train. Azure is on top of my dev project list after that great event! This platform offers endless opportunities for development and businesses. The cloud environment in general is safer, scales better, and is far more cost effective compared to run and maintain your own data center. Posted: Rainer Habermann

  • Tips for creating great game trailers

    - by Venesectrix
    Impressive trailers for your game can really help show players how awesome your game is, but I'm having trouble finding tips that describe how to create a great trailer. I would like to learn about the best way to decide trailer length, structure, music/sound, and content. Basically, what parts of my game do I show in a trailer, how should the scenes be organized, and how would you do the sound? Any advice on things to avoid would be great as well; for example, I read that splicing some video, switching to a screen with text, switching back to video, etc., probably isn't the best way to do it. Thanks!

  • Are There Any Examples of Uncle Bob's High-Falutin' Architecture?

    - by Jordan
    I just finished watching this presentation by Uncle Bob (as well as his "Architecture" section of his "Clean Code" videos), but I'm left wondering: Are there any examples out there of applications that implement this Entity-Boundary-Interactor (or Entity-Boundary-Controller) structure? At one point I downloaded the source code to FitNesse (the acceptance testing project he mentions often as an example of not only high test coverage but good architecture, since they were able to defer the decision to not use a database until the very end), and based on a quick glance of it it appears even this project doesn't seem to fit this pattern. Are there any nontrivial examples of this architecture out in the wild, or should I not bother even looking into it and chalk it up as "it would be great if you could get there, but nobody really does"?

  • PowerShell Try Catch Finally

    - by PointsToShare
    PowerShell Try Catch Finally I am a relative novice to PowerShell and tried (pun intended) to use the “Try Catch Finally” in my scripts. Alas the structure that we love and use in C# (or even – shudder of shudders - in VB) does not always work in PowerShell. It turns out that it works only when the error is a terminating error (whatever that means). Well, you can turn all your errors to the terminating kind by simply setting - $ErrorActionPreference = "Stop", And later resetting it back to “Continue”, which is its normal setting. Now, the lazy approach is to start all your scripts with: $ErrorActionPreference = "Stop" And ending all of them with: $ErrorActionPreference = "Continue" But this opens you to trouble because should your script have an error that you neglected to catch (it even happens to me!), your session will now have all its errors as “terminating”. Obviously this is not a good thing, so instead let’s put these two setups in the beginning of each Try block and in the Finally block as seen below: That’s All Folks!!

  • Hiring a Junior Developer, What should I ask?

    - by Jeremy
    We are currently hiring a junior developer to help me out, as I have more projects than I can currently manage. I have never hired anyone who wasn't a friend or at least an acquaintance. I have a phone interview with the only applicant that actually stood out to me (on paper), but I have never done this before. Our projects are all high scalability, data intensive web applications that process millions of transactions an hour, across multiple servers and clients. To be language/stack specific, we use ASP.Net MVC2, WebForms and C# 4, MSSQL 2008 R2, all running atop Windows Server 2008 R2 What should I ask him? How should I structure the phone call?

  • Get your content off Blogger.com

    - by Daniel Moth
    Due to blogger.com deprecating FTP users I've decided to move my blog. When I think of the content of a blog, 4 items come to mind: blog posts, comments, binary files that the blog posts linked to (e.g. images, ZIP files) and the CSS+structure of the blog. 1. Binaries The binary files you used in your blog posts are sitting on your own web space, so really blogger.com is not involved with that. Nothing for you to do at this stage, I'll come back to these in another post. 2. CSS and structure In the best case this exists as a separate CSS file on your web space (so no action for now) or in a worst case, like me, your CSS is embedded with the HTML. In the latter case, simply navigate from you dashboard to "Template" then "Edit HTML" and copy paste the contents of the box. Save that locally in a txt file and we'll come back to that in another post. 3. Blog posts and Comments The blog posts and comments exist in all the HTML files on your own web space. Parsing HTML files to extract that can be painful, so it is easier to download the XML files from blogger's servers that contain all your blog posts and comments. 3.1 Single XML file, but incomplete The obvious thing to do is go into your dashboard "Settings" and under the "Basic" tab look at the top next to "Blog Tools". There is a link there to "Export blog" which downloads an XML file with both comments and posts. The problem with that is that it only contains 200 comments - if you have more than that, you will lose the surplus. Also, this XML file has a lot of noise, compared to the better solution described next. (note that a tool I will refer to in a future post deals with either kind of XML file) 3.2 Multiple XML files First you need to find your blog ID. In case you don't know what that is, navigate to the "Template" as described in section 2 above. You will find references to the blog id in the HTML there, but you can also see it as part of the URL in your browser: blogger.com/template-edit.g?blogID=YOUR_NUMERIC_ID. Mine is 7 digits. You can now navigate to these URLs to download the XML for your posts and comments respectively: blogger.com/feeds/YOUR_NUMERIC_ID/posts/default?max-results=500&start-index=1 blogger.com/feeds/YOUR_NUMERIC_ID/comments/default?max-results=200&start-index=1 Note that you can only get 500 posts at a time and only 200 comments at a time. To get more than that you have to change the URL and download the next batch. To get you started, to get the XML for the next 500 posts and next 200 comments respectively you’d have to use these URLs: blogger.com/feeds/YOUR_NUMERIC_ID/posts/default?max-results=500&start-index=501 blogger.com/feeds/YOUR_NUMERIC_ID/comments/default?max-results=200&start-index=201 ...and so on and so forth. Keep all the XML files in the same folder on your local machine (with nothing else in there). 4. Validating the XML aka editing older blog posts The XML files you just downloaded really contain HTML fragments inside for all your blog posts. If you are like me, your blog posts did not conform to XHTML so passing them to an XML parser (which is what we will want to do) will result in the XML parser choking. So the next step is to fix that. This can be no work at all for you, or a huge time sink or just a couple hours of pain (which was my case). The process I followed was to attempt to load the XML files using XmlDocument.Load and wait for the exception to be thrown from my code. The exception would point to the exact offending line and column which would help me fix the issue. Rather than fix it in the XML itself, I would go back and edit the offending blog post and fix it there - recommended! Then I'd repeat the cycle until the XML could be loaded in the XmlDocument. To give you an idea, some of the issues I encountered are: extra or missing quotes in img and href elements, direct usage of chevrons instead of encoding them as &lt;, missing closing tags, mismatched nested pairs of elements and capitalization of html elements. For a full list of things that may go wrong see this. 5. Opportunity for other changes I also found a few posts that did not have a category assigned so I fixed those too. I took the further opportunity to create new categories and tag some of my blog posts with that. Note that I did not remove/change categories of existing posts, but only added.   In an another post we'll see how to use the XML files you stored in the local folder… Comments about this post welcome at the original blog.

  • Big Data – Evolution of Big Data – Day 3 of 21

    - by Pinal Dave
    In yesterday’s blog post we answered what is the Big Data. Today we will understand why and how the evolution of Big Data has happened. Though the answer is very simple, I would like to tell it in the form of a history lesson. Data in Flat File In earlier days data was stored in the flat file and there was no structure in the flat file.  If any data has to be retrieved from the flat file it was a project by itself. There was no possibility of retrieving the data efficiently and data integrity has been just a term discussed without any modeling or structure around. Database residing in the flat file had more issues than we would like to discuss in today’s world. It was more like a nightmare when there was any data processing involved in the application. Though, applications developed at that time were also not that advanced the need of the data was always there and there was always need of proper data management. Edgar F Codd and 12 Rules Edgar Frank Codd was a British computer scientist who, while working for IBM, invented the relational model for database management, the theoretical basis for relational databases. He presented 12 rules for the Relational Database and suddenly the chaotic world of the database seems to see discipline in the rules. Relational Database was a promising land for all the unstructured database users. Relational Database brought into the relationship between data as well improved the performance of the data retrieval. Database world had immediately seen a major transformation and every single vendors and database users suddenly started to adopt the relational database models. Relational Database Management Systems Since Edgar F Codd proposed 12 rules for the RBDMS there were many different vendors who started them to build applications and tools to support the relationship between database. This was indeed a learning curve for many of the developer who had never worked before with the modeling of the database. However, as time passed by pretty much everybody accepted the relationship of the database and started to evolve product which performs its best with the boundaries of the RDBMS concepts. This was the best era for the databases and it gave the world extreme experts as well as some of the best products. The Entity Relationship model was also evolved at the same time. In software engineering, an Entity–relationship model (ER model) is a data model for describing a database in an abstract way. Enormous Data Growth Well, everything was going fine with the RDBMS in the database world. As there were no major challenges the adoption of the RDBMS applications and tools was pretty much universal. There was a race at times to make the developer’s life much easier with the RDBMS management tools. Due to the extreme popularity and easy to use system pretty much every data was stored in the RDBMS system. New age applications were built and social media took the world by the storm. Every organizations was feeling pressure to provide the best experience for their users based the data they had with them. While this was all going on at the same time data was growing pretty much every organization and application. Data Warehousing The enormous data growth now presented a big challenge for the organizations who wanted to build intelligent systems based on the data and provide near real time superior user experience to their customers. Various organizations immediately start building data warehousing solutions where the data was stored and processed. The trend of the business intelligence becomes the need of everyday. Data was received from the transaction system and overnight was processed to build intelligent reports from it. Though this is a great solution it has its own set of challenges. The relational database model and data warehousing concepts are all built with keeping traditional relational database modeling in the mind and it still has many challenges when unstructured data was present. Interesting Challenge Every organization had expertise to manage structured data but the world had already changed to unstructured data. There was intelligence in the videos, photos, SMS, text, social media messages and various other data sources. All of these needed to now bring to a single platform and build a uniform system which does what businesses need. The way we do business has also been changed. There was a time when user only got the features what technology supported, however, now users ask for the feature and technology is built to support the same. The need of the real time intelligence from the fast paced data flow is now becoming a necessity. Large amount (Volume) of difference (Variety) of high speed data (Velocity) is the properties of the data. The traditional database system has limits to resolve the challenges this new kind of the data presents. Hence the need of the Big Data Science. We need innovation in how we handle and manage data. We need creative ways to capture data and present to users. Big Data is Reality! Tomorrow In tomorrow’s blog post we will try to answer discuss Basics of Big Data Architecture.

  • Teamwork 101 for the solo newbie

    - by clankercrusher
    Forgive my newbishness but I have a question to ask about teamwork...mainly because I stink at it. Most of my projects up until this point have been solo so I have a very limited experience with teamwork. I did make graphics for a game that was being developed by several people, but that was completely different than programming with several different people. Right now I'm working with someone else on an indie MMO along with a few other team members. I've already made some pretty stupid mistakes, (like rewriting EVERYTHING) so I have two questions for you guys: 1) What are some of the most common mistakes that people make in a team environment and how can they be avoided? 2) How can the structure of your program be altered to allow for multiple teams members to work on different parts of the program at the same time? P.S. Is this the right stack exchange site for this type of question? (if not, where does it go? Thanks)

  • Clockwork: A 40,000 Piece K’Nex Ball Machine [Video]

    - by Jason Fitzpatrick
    You may have built a simple marble raceway out of construction toys like LEGO or K’Nex at some point in your life. No matter how grand a raceway it was, we can assure you it had nothing on this 40,000 piece room-sized monster. The creator, Austron, writes: This is Clockwork, my fifth major K’nex ball machine, and my largest and most complex K’nex structure to date. It took 8 months to build, has over 40,000 pieces, over 450 feet of track, 21 different paths, 8 motors, 5 lifts, and a one-of-a-kind computer-controlled crane, as well as two computer-controlled illuminated K’nex balls. For a more in-depth look at the construction we suggest checking out both his YouTube channel and his build blog.

  • how should I network my turn based game?

    - by ddriver1
    I'm writing a very basic turn based strategy game which allows a player to select units and attack enemy units on their turn. The game is written in Java using the slick2d library and I plan to use kyronet for the networking api. I want the game to be networked, but I do not know how I should go about it. My current idea is to connect two users together, and the first one to join the game becomes the game host, while the other becomes the client. However after reading http://gafferongames.com/networking-for-game-programmers/what-every-programmer-needs-to-know-about-game-networking/ it seems my game would be suited to a peer to peer lockstep model. Would that make programming the networking side much easier? Any suggestions on how I should structure my networking would be greatly appreciated

  • MySpace est officiellement à vendre, mais quelle firme pourrait bien vouloir le racheter ?

    MySpace est officiellement à vendre, mais quelle firme pourrait bien vouloir le racheter ? Tout à une fin, et il semble bien que MySpace puisse en faire bientôt l'expérience. Le réseau social qui était autrefois leader, s'est vu balayé d'un revers de la main par l'arrivée de Facebook, vers lequel la majorité de ses abonnés ont migré. En 2005, c'était News Corporation (qui appartient à Rupert Murdoch), qui avait racheté le site à prix d'or (580 millions de dollars !). Depuis, sa relance est un échec et la dégringolade continue. Le groupe de presse a donc décidé de s'en séparer, et lui cherche désormais un nouveau propriétaire. "Avec un nouvel accent mis sur les contenus et une nouvelle structure, nous pens...

  • New Wordpress posts generate 404 error.

    - by Steve
    I had a working installation of WordPress, and I recently encountered an issue where when I tried to login to the back-end, the browser would redirect to the login URL of the previous domain WordPress was installed on. I fixed this by reinstalling WordPress, and I can now login to the backend, but any new posts I make, or old posts I have generate 404 errors. Additionally, if I try to navigate to any category page, I again receive a 404 error. I have looked at the wp_posts table of my database, and the GUID field each contains the correct domain name and URL structure. What should I be checking here? Site in question.

  • Create a Social Community of Trust Along With Your Federal Digital Services Governance

    - by TedMcLaughlan
    The Digital Services Governance Recommendations were recently released, supporting the US Federal Government's Digital Government Strategy Milestone Action #4.2 to establish agency-wide governance structures for developing and delivering digital services. Figure 1 - From: "Digital Services Governance Recommendations" While extremely important from a policy and procedure perspective within an Agency's information management and communications enterprise, these recommendations only very lightly reference perhaps the most important success enabler - the "Trusted Community" required for ultimate usefulness of the services delivered. By "ultimate usefulness", I mean the collection of public, transparent properties around government information and digital services that include social trust and validation, social reach, expert respect, and comparative, standard measures of relative value. In other words, do the digital services meet expectations of the public, social media ecosystem (people AND machines)? A rigid governance framework, controlling by rules, policies and roles the creation and dissemination of digital services may meet the expectations of direct end-users and most stakeholders - including the agency information stewards and security officers. All others who may share comments about the services, write about them, swap or review extracts, repackage, visualize or otherwise repurpose the output for use in entirely unanticipated, social ways - these "stakeholders" will not be governed, but may observe guidance generated by a "Trusted Community". As recognized members of the trusted community, these stakeholders may ultimately define the right scope and detail of governance that all other users might observe, promoting and refining the usefulness of the government product as the social ecosystem expects. So, as part of an agency-centric governance framework, it's advised that a flexible governance model be created for stewarding a "Community of Trust" around the digital services. The first steps follow the approach outlined in the Recommendations: Step 1: Gather a Core Team In addition to the roles and responsibilities described, perhaps a set of characteristics and responsibilities can be developed for the "Trusted Community Steward/Advocate" - i.e. a person or team who (a) are entirely cognizant of and respected within the external social media communities, and (b) are trusted both within the agency and outside as practical, responsible, non-partisan communicators of useful information. The may seem like a standard Agency PR/Outreach team role - but often an agency or stakeholder subject matter expert with a public, active social persona works even better. Step 2: Assess What You Have In addition to existing, agency or stakeholder decision-making bodies and assets, it's important to take a PR/Marketing view of the social ecosystem. How visible are the services across the social channels utilized by current or desired constituents of your agency? What's the online reputation of your agency and perhaps the service(s)? Is Search Engine Optimization (SEO) a facet of external communications/publishing lifecycles? Who are the public champions, instigators, value-adders for the digital services, or perhaps just influential "communicators" (i.e. with no stake in the game)? You're essentially assessing your market and social presence, and identifying the actors (including your own agency employees) in the existing community of trust. Step 3: Determine What You Want The evolving Community of Trust will most readily absorb, support and provide feedback regarding "Core Principles" (Element B of the "six essential elements of a digital services governance structure") shared by your Agency, and obviously play a large, though probably very unstructured part in Element D "Stakeholder Input and Participation". Plan for this, and seek input from the social media community with respect to performance metrics - these should be geared around the outcome and growth of the trusted communities actions. How big and active is this community? What's the influential reach of this community with respect to particular messaging or campaigns generated by the Agency? What's the referral rate TO your digital services, FROM channels owned or operated by members of this community? (this requires governance with respect to content generation inclusive of "markers" or "tags"). At this point, while your Agency proceeds with steps 4 ("Build/Validate the Governance Structure") and 5 ("Share, Review, Upgrade"), the Community of Trust might as well just get going, and start adding value and usefulness to the existing conversations, existing data services - loosely though directionally-stewarded by your trusted advocate(s). Why is this an "Enterprise Architecture" topic? Because it's increasingly apparent that a Public Service "Enterprise" is not wholly contained within Agency facilities, firewalls and job titles - it's also manifested in actual, perceived or representative forms outside the walls, on the social Internet. An Agency's EA model and resulting investments both facilitate and are impacted by the "Social Enterprise". At Oracle, we're very active both within our Enterprise and outside, helping foster social architectures that enable truly useful public services, digital or otherwise.

  • Softbody with complex geometry

    - by philipp
    I have modeled an Handball, based on the tutorial here, with a custom texture. Now I am trying to animate this model with the reactor module as a soft body. Therefor I have watched and tried a lot of tutorials and for animating a simple Sphere everything works fine. But if i try to use the model I have created, than it results in the crash of max or an animation that shows a crystal like structure that transforms itself to another crystal. Is it possible to animate this kind of complex geometry as a soft body and am i just setting the values wrong? If yes, which are the important ones I should check? Thanks in advance! Greetings philipp
