• OpenGL: Implementing transformation matrix stack

  - by Jakub M.

  In a newer OpenGL there is no matrix stack. I am working on a simple display engine, and I am going to implement the transformation stack. What is a common strategy here? Should I build a push/pop stack, and use it with a tree representing my model? I suppose this is the "old" approach, that was deprecated in the newer OpenGL versions. Maybe then it is not the best solution (it was removed for some reason)

• Tomcat Http and Https on the same port

  - by Ofri Dagan

  Hi, I have a web-service endpoint and a http connector on port X. At some point this endpoint needs to switch to https, but on the same port! (I know this is not the normal way of doing things, but this is what my clients expect from an old server they are using...) Is there a way to do it in tomcat?

• Playground for Artificial Intelligence?

  - by Dolph Mathews

  In school, one of my professors had created a 3D game (not just an engine), where all the players were entirely AI-controlled, and it was our assignment to program the AI of a single player. We were basically provided an API to interact with the game world. Our AI implementations were then dropped into the game together, and we watched as our programs went to battle against each other. It was like robot soccer, but virtual, and with lots of big guns. I'm now looking for anything similar (and open source) to play with. (Preferably in Java, but I'm open to any language.) I'm not looking for a game engine, or a framework... I'm looking for a complete game that simply lacks AI code... preferably set up for this kind of exercise. Suggestions?

• jQuery Click event on object added with JavaScript not working.

  - by Hultner

  I'm work on a quiz for school but I've bumped into a problem. I got a javascript file for custom radio buttons (CUSTOM FORM ELEMNTS by Ryan Fait if it's helping). The script hides the input buttons and adds custom styled spans instead. Now what I want, when I click one of these JavaScript added spans I want to remove disabled for a button called "Next Question" which when pressed takes you to the next question. The reason for this is that I don't want people to accidently got to the next question without choosing a answer. The problem is when I press the added spans nothing happens but when I press another identical span which I have added in the html it works just as intended. The span got the class radio which is the class I'm looking for in the jQuery. Here's the test page with the error on: http://hultner.se/graphicsquiz/livetest/livetest.php Short: Can't get jQuery .click() functions to work with spans added using JavaScript earlier in the document.

• What should I do that GWT use <th> instead of <td>?

  - by Paulus

  To build a HTML table I use direct DOM instead of a predefined Widget to set thead and tbody. But when I insert a cell with the insertCell() method GWT inserts an td element but should insert an th element. So TableElement table = Document.get().createTableElement(); TableSectionElement thead = table.createTHead(); TableRowElement headRow = thead.insertRow(-1); headRow.insertCell(-1).setInnerText( "header1" ); gives table/thead/tr/td but should give table/thead/tr/th Any idea how to solve this problem? Use the "old-school" DOM.createXXX()-Methods?

• Tracing or Logging Resource Governor classification function behavior in Sql Server 2008

  - by nganju

  I'm trying to use the Resource Governor in SQL Server 2008 but I find it hard to debug the classification function and figure out what the input variables will have, i.e. does SUSER_NAME() contain the domain name? What does the APP_NAME() string look like? It's also hard to verify that it's working correctly. What group did the function return? The only way I can see this is to fire up the performance monitor and watch unblinkingly for little blips in the right CPU counter. Is there some way I can either run it in Debug mode, where I can set a breakpoint and step through and look at variable values, or can I at least do the old-school method of writing trace statements to a file so I can see what's going on? Thanks...

• Question about OOP and objects.

  - by loddn

  I have a school assignment, a Dog Show. My assignment is to create a website where vistors can display results and Judges and Secretary can admin, crud. I have a small problem one part of the assignment. The result should be based on two protokols from different judges and after that checked by the secretary before the result is displayed for the user. I have to say i'm fairly new to programming and so i need some smart suggestions on how to design and implement this. The assignment should cover both a db and c# (.net mvc). Q1: How do i create a object (result)that depends on two other objects(protocol)? Is that even needed? Q2: How to solve this in a relational db?

• Can't export release build / compile for Adobe Air 1.0

  - by Shawn Simon

  I opened up an old project in Flex Builder 3 which runs on Adobe AIR 1.0. I believe it was originally written in Flex Builder 2. When I try to run the air app, nothing happens. When I try to export a release build, I get this error: If I change the main-app.xml file to use the 1.5 version of the namespace, it builds fine. Unfortunately, the clients environment runs on 1.0. Ideas?

• Is Spring.Threading.Helpers still supported?

  - by Paul Morrison

  I am converting some old C# code, and it has a CountDownLatch using a package called Spring.Threading.Helpers. The odd thing is that I can't find this package on Google - so a) is it still supported? And, if so, where is it documented? b) What I really want to do is wait for a count to get to zero, but interrupt every so many msecs. Would it just be simpler to set up another thread, and do WaitOnes on an Event specifying an interval? TIA

• How do I get the name of the parent folder in a command prompt?

  - by Bernhard Hofmann

  I'm in a Windows Command Line and want the parent folder in a variable. Assuming current directory is "C:\foo\bar", how can I get the value "bar"? I'm expecting something like a "find last backslash in CD and that's it". And please, no powershell references; I want plain old Windows Command Line operations.

• Creating a Java platform game as easily as possible

  - by directx

  I need to create a Java-based platformer game for a high school project (not computer science related), and I want to spend as little time on technical stuff as possible. I'm already experienced in Java, and I already have most of the gameplay, graphics, etc. All I need to do is code it. I've looked and I'm considering one of two options that do not involving coding a game from scratch: Copy an existing Java platformer (best option, but I can't find an open source Java platformer) Use a Java game engine to avoid coding from scratch. I've looked at JGame but I'm not sure if it's the best bet for a platformer.

• Where can I find the transaction protocol used by Automated Teller Machines?

  - by Dave

  I'm doing a grad-school software engineering project and I'm looking for the protocol that governs communications between ATMs and bank networks. I've been googling for quite a while now, and though I'm finding all sorts of interesting information about ATMs, I'm surprised to find that there seems to be no industry standard for high-level communications. I'm not talking about 3DES or low-level transmission protocols, but something along the lines of an Interface Control Document; something that governs the sequence of events for various transactions: verify credentials, withdrawal, check balance, etc. Any ideas? Does anything like this even exist? I can't believe that after all this time the banks and ATM manufacturers are still just making this up as they go. A shorter question: if I wanted to go into the ATM software manufacturing business, where would I start looking for standards?

• creating a wordpress dev enviornment and uploading to production

  - by Jeff

  I am an old school java developer who is considering a using wordpress. I'm used to developing locally on my PC (yeah yeah not even a mac) and then ftping my files up to a production environment on a remote server. My high level review of wordpress gives me the impression that typically there is no concept of lower environments and that all updates occur directly in production. Is this the case? If not, can someone explain how one goes about uploading the files to a web site? Thanks, Jeff

• How can I combine result and subquery for IN comparison (mysql)

  - by user325804

  In order for a school project i need to create the following situation within one mysql query. The situation is as such, that a child's tags and a parent's tags need to be combined into one, and compared to a site's tags, depending on a few extra simple equals to lines. For this to happen I only see the option that the result of a subquery is combined with a sub query within that query, as such: SELECT tag.*, (SELECT group_concat(t1.id, ',', (SELECT group_concat(tag.id) FROM adcampaign INNER JOIN adcampaign_tag ON adcampaign.id = adcampaign_tag.adcampaign_id INNER JOIN tag ON adcampaign_tag.tag_id = tag.id WHERE adcampaign.id = 1)) FROM ad, ad_tag, tag AS t1 WHERE ad.id = ad_tag.ad_id AND ad_tag.tag_id = t1.id AND ad.adcampaign_id = 1 AND ad.agecategory_id = 1 AND ad.adsize_id = 1 AND ad.adtype_id = 1) as tags FROM tag WHERE tag.id IN tags But the IN comparison only returns the first result because now the tags aren't a list but a concanated string. Anyone got any suggestion on this? I really need a way to combine it into one array

• create a new model instance version instead of update

  Hi, I have a model with a version field - autocreate timestamp. When a model instance is being saved I want to create a new instance with a new timestamp instead of updating the old model instance. Is it possible? I thought of overriding the model save() method but I don't know how to create a new instance without creating a infinite save() loop. Thanks

• Real world examples of tree structures

  - by Arec Barrwin

  I'm looking for some examples of tree structures that are used in commercial/free software projects, modern or old. I can see examples on wikipedia, but I am looking for more concrete examples and how they're used. For example primary keys in databases are (from what I've read) stored in BST structure or a variation of the BST (feel free to correct me on this) My question isn't limited Binary Search Trees (BSTs), it can include any variation such as red-black, AVL and so on.

• Most Efficient way to set Register to 1 or (-1)

  - by Bob

  I am taking an assembly course now, and the guy who checks our home assignments is a very pedantic old-school optimization freak. For example he deducts 10% if he sees: mov ax, 0 instead of: xor ax,ax even if it's only used once. I am not a complete beginner in assembly programing but I'm not an optimization expert, so I need your help in something (might be a very stupid question but I'll ask anyway): if I need to set a register value to 1 or (-1) is it better to use: mov ax, 1 or do something like: xor ax,ax inc ax I really need a good grade, so I'm trying to get it as optimized as possible. ( I need to optimize both time and code size)

• designing classes and objects in .net for a restaurant assignment

  - by Dell Boy

  I have received an assignment at School for creating a Restaurant site. I have to use objects and classes (OOP) for my assignment. I have the foundations of the OOP in .net, but what I don't know is how can I design this assignment to be object-oriented. I don't know how to start it. The requirement is like this: The menu has to be saved in a database and retrieved from it. The menu is devided in appetizers, Salades, Main Meal, Pastas, Wines, Beverages, Extras, Do I create classes like this: Base Class: Menu Derived classes: Appetizers, Salades, Main meal, Pastas, wines, etc. If you have a good example about how to create classes from a Menu that will be great. You don't have to rely on the example I gave above. The menu can be anything. I can deside what the menu will contain. thanks a lot. I am waiting for some help. Please
