• UDK/ UnrealScript class interaction? HUD advice?

  - by Holly

  Beginner basics requested here, While i'm familiar with the basics of OOP programming i've just started looking as UnrealScript for a game i had made in the UDK editor up to now. I have a class that extends UTHUD and another that extends UDKPAWN. I have the pawn destroyed when its been shot 3 times and some basic helloworld text displaying in my HUD but i'm completely lost as to how one would get some sort of feedback between the two classes going on? What i would like to do to start off, is have some text that says something like "Amount of baddies killed: 0" Displayed on the HUD which would then increment each time the player destroyed one of my pawns. I'm sorry if this is an inappropriate question but i've never really worked within a framework like this before and wasn't sure where to go for help to get my footing. All advice appreciated!

• [OT] : Tagged : SQL Dream Cars

  - by AaronBertrand

  Steve Jones ( blog | twitter ) posted an entry today called "SQL Dream Cars," where he talks briefly about 5 of the cars he would love to own. He then tagged a few of us to share our lists. Before I get to mine, I wanted to reflect a bit on one of Steve's choices, the Ferrari 308 GTS. I remember when I was a kid, maybe 10 or 11 years old - after Magnum PI made that Ferrari 308 so popular - that a local doctor in North Bay had one. His name was Dr. Fazzarri (and I apologize if I've spelled that wrong);...(read more)

• Developing a DVR software using a hardware KIT

  - by Leron

  I'm currently thinking about a project for my masters degree graduation. I start researching for options to make my own video streaming software based on a premade hardware kit having not much knowledge about what I'll exactly need that will match my needs. My search led me to the DVR (Digital Video Recorder) cards which seems to be the closest to what I need, but still I can't find out a few basic things so I decide to ask for them here. Currently I haven't find a lot of manufacturers that offers such kits so where I can look and have some options to choose from? There are a lot of DVR products on the market but they already have a software written for them and even if I buy one they just don't give any documentation or sdk's so buying such is not an option I need a DVR card made exactly for software programers and not end users. Are there a preferred manufacturers that provide such kind of devices with good and developer-friendly documentation? Also - I prefer to do all this with Java, is this an option (I think I will make it with .NET too but really prefer Java as a language of choice)

  CoffeeScript is a handy preprocessor for JavaScript, as shown in a quick demo below on YouTube, using the CoffeeScript plugin for NetBeans IDE. Right now, the NetBeans Plugin Portal doesn't have a CoffeeScript plugin for NetBeans IDE 7.4, but not to worry, the NetBeans IDE 7.3 plugin works just fine. http://plugins.netbeans.org/plugin/39007/coffeescript-netbeans Here's a small YouTube clip I made today showing how it all works: Also read this very handy and detailed NetBeans tutorial, on which I based the demo above: https://netbeans.org/kb/docs/web/js-toolkits-jquery.html Related info: http://www.youtube.com/watch?v=QgqVh_KpVKY http://www.ibm.com/developerworks/library/wa-coffee1/ http://blog.sethladd.com/2012/01/vanilla-dart-ftw.html http://api.jquery.com/fadeOut/

• Where can a list of Desktop web browsers be found at?

  - by Sn3akyP3t3

  I have another question posted in regards to the practicality of whitelisting. In this question I'm simply looking for an frequently updated list of top known used Desktop web browsers to use as part of my whitelist. I'm not trying to target any specific OS so please show one, show all. The list of browsers for desktops isn't exploding, but it does grow. I've only recently been made aware of other browsers that have multiple rendering engines. I'm not always on top of the text based browsers found out there either. I'm aware of the mobile browser platform and there is an active list used with regular expression for identification purposes that I will use as well as whatever I can find for the desktop platforms.

• Impressions and traffic dropped by 70 %

  - by Louise

  Can anyone advise why my impressions dropped and traffic as well? I used to have very generic keywords such as: anti aging, anti wrinkle, face cream, eye cream. I thought they were bad and made the keywords more specific: anti wrinkle eye cream, anti aging face cream, etc. Following that change, my impressions and traffic dropped dramatically! I used to get 45+ visitors a day, now I get 15- visitors a day. What is the way forward? I thought what I did to the keywords was good?

• Constructive ways to answer "What was your most challenging project? and why?"

  - by tau

  I am asked this question many times in the interviews. What was your most challenging project -- and why? I get confused about which project to tell them and why some project would look challenging or non-challenging. What are they looking for in the answer? Any software is a challenge before it gets started and it becomes a normal software engineering task after it has finished. All softwares I made were challenging until they got finished. Do I misunderstood the word "challenge"? What's wrong in my thinking? What's an appropriate and constructive way to approach this question?

• Static HTML to Wordpress Migration SEO Implications?

  - by Kayle

  Recently, I migrated a client's site to a new server and a new home within wordpress so they could more easily edit their website and start a blog section. The static site was 10 years old a was showing up at place #3 for it's primary keyword, consistently, according to my client, and has dropped to rank #6-8 following the migration. At launch, we made sure the urls were identical (save the removal of ".htm" which we used 301 redirects to compensate for) and we generated a new XML map and pinged google with the new site. We keep a 404 log to make sure we're not losing any incoming links. We also have Google Webmaster Tools on this site and have zero errors/suggestions, everything seems ok. I was told by numerous sources that Google would not penalize us for the use of 301s, but it's the only thing I can think of right now that is different about the site, other than the platform. Any ideas about what we could be getting docked for?

• Unity 3D - Error BCE0019 , " 'paused' is not a member of PauseScript"

  - by user3666251

  I am trying to make a game for Android in Unity. Came to the part where I have to make a pause menu option. Made a GUITexture and placed it on the top right side of the screen then I attached this script to it : #pragma strict function OnMouseDown(){ this.paused = !this.paused; } function OnGUI(){ if(this.paused){ if (GUI.Button(Rect(10,10,100,50),"Restart")){ Application.LoadLevel(Application.loadedLevel); } // Insert the rest of the pause menu logic } } It gives me this error : "Assets/Scripts/PauseScript.js(4,10): BCE0019: 'paused' is not a member of 'PauseScript'. " "PauseScript" is the name of my pause script. Thank you.

• In concept how is Animation done?

  - by sharethis

  The first approaches in animation for my game relied mostly on sine and cosine functions with the time as parameter. As a jump a perfect sine function is acceptable but for motions of arms, weapons or face it would look quite unnatural. Moreover patching every animation out of sine and cosine is stretched to its limits soon. I head of skeletons and rigging already. Although I could not implement skeletal animations I can't imagine that quite natural animations in major games are made of static predefined motion states. So how in general is animation done today?

• Maya Animated Character export for XNA 4.0 problem

  - by FahidK

  To begin with, I'm trying to export an animated character in .fbx format from Maya 2013 to XNA 4.0 In Maya, The Model has a basic rig and the animations are in clips made in the Trax editor. so the issue i'm having is after selecting the model and the root joint and then hitting export in .fbx format, for some reason when i open the exported .fbx file the joint system is detached from the model with no animation. Btw, i have the animations in clips so that they can be called in code, for example "run","walk","attack". So, what can i do to solve this problem? Thank you.

• Does XNA/MonoGame have a text caching mechanism, or has an open source one been implemented?

  - by Casey

  I'm playing around with MonoGame, and I've noticed the SpriteFont class draws static text very inefficiently. Each time the text is drawn the spacing is recalculated. This isn't a big deal on my quad core PC, but on mobile applications it might be a problem. Before I go and program some text which caches the arrangement of its letters in an array and then feeds that array to the SpriteBatch, I would like to make sure there isn't something available to do this already, either in MonoGame itself or a class someone has implemented and made available for general use.

• Can i make a launcher shortcut perform different actions based on a condition

  - by Nirmik

  What i want to do is pretty simple to understand. I want the same launcher shortcut to act like a ON/OFF swith for eg. Like suppose i have made a launcher to start LAMPP with the command gksudo /opt/lampp/lampp start This works properly to start lampp. Now,what i want to do is,If LAMPP is not on,the launcher should execute the above command and start lampp.While if lampp is on,I want ti to execute the command gksudo /opt/lampp/lampp stop and stop lampp. I want these 2 commands to be executed by the same launcher where the command to be executed is decided on the basis of a condition(LAMPP being ON or OFF in the above example) Can i do this? and how? I guess writing a bash script and then making the launcher execute the bash script would do it.but then how do i check weather lampp is on of off?

• FTP over ssh hangs on "Connection established: Waiting for Welcome Message"

  - by Siriss

  I have looked far and wide and have not quite found the answer. I am running ubuntu 11.10, openssh, and vsftpd. I am trying to configure my FTP to tunnel over ssh. My ssh connection works just fine and I can create the tunnel to my FTP port. When I go to use Filezilla to connect, it hangs at "Waiting for Welcome Message". I think it is an iptables issue, but I can't seem to figure out what needs to be changed. When I take iptables down, it connects just fine. I don't want to open any more external ports, just my one SSH port, and I can't seem to get it right on the internal port forwarding rule. I always end up opening it to the outside. I would love some help if anyone has any ideas and I hope I have made it clear. Thank you in advance!!

• Java-Powered Robot Named NAO Wows Crowds

  - by Tori Wieldt

  He drew a crowd where he went at JavaOne. And only being 22.5 inches/573 mm tall, that's pretty impressive. Nao (pronounced now) is an autonomous, programmable humanoid robot developed by Aldebaran Robotics, a French robotics company. Over 200 academic institutions worldwide have made use of the robot. In this video from JavaOne, Nicolas Rigaud shows off the NAO robot which you can control with Java. We are eager to see what Java developers can do with a robot that can walk, talk, see, hear, and dance. &amp;amp;amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;amp;amp;quot;&amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;amp;amp;gt; You can see several pictures in the blog Aldebaran Robotics at JavaOne.

• Microsoft gives you your cache back

  - by Dave Ballantyne

  The system works and its called Microsoft Connect , who would of thought it :) Following on from my previous blog post MicroSoft – Follow best practices, on the connect item , the followup stated that changes had been made in 2008.  I genuinely thought that a change would take an age to trickle through to the customer. But after firing up 2008R2 RTM and examining the SqlAgent traffic with profiler , where before i would see non-parameterized sql, I now see RPC calls.    Excellent , i get my cache back.

• Execure a random command from .txt file?

  - by Alberto Burgos

  I have a Ubuntu server, and I'm trying to print a Twitter quote using the app "twidge". So I made a list of tweets on a .txt file. I want to print one tweet (per line) from that file and send it to Twitter via twidge (or what ever other method was possible). I can print a random phrase with shuf: shuf -n 1 /var/www/tweets.txt and it works. It sends me back one of the tweets, but, it does not send it to Twitter, even if the "in line" phrase is a command. i.e: twidge update "bla bla bla" It just prints on the screen, but don't send it to Twitter. I tried turning the .txt to .sh, but don't work... any idea? by the way, i want to use it with crontab, something like this: 15 * * * * shuf -n 1 /var/www/tweets.txt

• Parleys Testimonial at GlassFish Community Event, JavaOne 2012

  - by arungupta

  Parleys.com is an e-learning platform that provide a unique experience of online and offline viewing presentations, with integrated movies and chaptering, from the top notch developer conferences and about 40 JUGs all around the world. Stephan Janssen (the Devoxx man and Parleys webmaster) presented at the GlassFish Community Event at JavaOne 2012 and shared why they moved from Tomcat to GlassFish. The move paid off as GlassFish was able to handle 2000 concurrent users very easily. Now they are also running Devoxx CFP and registration on this updated infrastructure. The GlassFish clustering, the asadmin CLI, application versioning, and JMS implementation are some of the features that made them a happy user. Recently they migrated their application from Spring to Java EE 6. This allows them to get locked into proprietary frameworks and also avoid 40MB WAR file deployments. Stateless application, JAX-RS, MongoDB, and Elastic Search is their magical forumla for success there. Watch the video below showing him in full action: More details about their infrastructure is available here.

• SQL Auto Close Options

  - by Dave Noderer

  Found an interesting thing that others have run across but it is the first time I’ve seen it. A customer emailed to say that the SQL 2008 db that I had helped him with seemed to be going into recovery mode on a regular basis while watching the SQL Management Studio screen. Needless to say he was a bit nervous and about to take some drastic steps. Eventually he found that the Auto Close option was set to true. When this is set to true, the database automatically closes all connections and unlocks the mdf file after 300 milliseconds. When a new connection is made it spins backup… Great for xcopy deployment on a client machine but not a multi-user server based application. So the warning… if you have started a database with SQL express and then move it to a production SQL server, make sure you check that the Auto Close option is set to false. See options screen below:
