  • Should Swing knowledge be required from Java programmers?

    - by Anto
    Swing is an integral part of the Java API. It is also the most popular GUI framework for Java. I still wonder, should every Java programmer still know, or at least be pretty familiar with, Swing (possibly excluding web developers)? There are alternatives (e.g. SWT), but they are not very widely used (compared to Swing). What do you think about requiring Swing knowledge from Java programmers? If such knowledge is important, to what degree? Are the basics enough or not? The reason I wonder is because I really don't like Swing but wonder if I still should brush up my skills in it. I'm able to create simple GUIs in it, but I would definitely not say that I know Swing well.

  • Drawing graphics in Java game

    - by wolf
    I am quite new to game development, so here is a question (maybe a stupid one): In my sidescroller i have a bunch of different graphics objects that i need to draw (player, background tiles, creatures, projectiles etc). Most tutorials i've read so far show that each object has its own draw method, which is then called from some other method. What if I had one method that does all the drawing? Lets say i keep all my objects in an array or queue (or multiple arrays) and then go through each of them, get an image and draw it. So basically would it be better (and why) to have each object have its own draw method or one method that does all the drawing? Or does it matter at all? I feel like the second option is more comfortable, because then all the stuff to do with drawing would be in one place...

  • The Great Ball Contraption: A Massive Automated LEGO Construction

    - by Jason Fitzpatrick
    This massive LEGO construction combines 17 distinct modules into a lengthy factory-like conveyance system for five hundred LEGO balls. The variety and creativity of the methods employed is, dare we say, dazzling. Slotted robotic arms? Screw lifts? Handshake object transfers? Catapults that shoot baskets? The sheer number of creative and novel solutions LEGO builder Akiyuky employs to move the balls through his machine left us mesmerized for the whole seven minute video.

  • Host Matching Interview Tips?

    - by Lambert
    So I've gotten past the technical interviews for a company, and now I'm having an interview with my potential host for an internship during the summer. What are some tips for interviews like these? I know they're not really technical, but I'm not sure what exactly they are meant to gauge. Any tips on what to say, how to show my interest in the project, questions I should ask, etc.? Edit: Side question: What's a good synonym for the word "interesting" or "interested"? I find that I use those words a bit too often (e.g. "I'm definitely interested in working on the front-end!" or "Yeah, that sounds really interesting, I would love learning more about it." or "Those all sound really interesting, I'm definitely interested in all of them!", etc.)... but I can't seem to find any good synonyms. (Online sites don't really give me good synonyms.) Any ideas?

  • Hosted CMS - Based On Drupal [closed]

    - by Eddy Freeman
    I just want a little clarification concerning hosted CMS like shopify.com, solidshops.com (i learnt shopify runs on ruby on rails) so let me be specific about hosted CMS based on Drupal :: www.buzzr.com, www.drupalgardens.com and www.pagebuild.net etc.. What i want to know is 1) Do they use the Multi-Site feature in Drupal to automatically creates all those 1000's of sites they host when a user sign up? 2) Do they create those 1000's of sites as sub-sites(if you like let me say subdomains)? 3) Do they use a different way other than the Multi-Site in Drupal?

  • 2.5D action RPG game

    - by Phorden
    I want to make a 2.5D action RPG game in the next say five years. I need to learn a language first and I have started with C#. I haven't gotten too far into learning it and I would like advice on the best way to approach making a game like this in the long run. Work with XNA studios or stop and learn C++ and UDK? Or maybe there is another good way to approach this. I want to learn programming, so just using a visual editor without learning to code is not the way I want to go. I also don't want to write my game engine from scratch. I'm all ears for advice.

  • Workflows in SharePoint 2013, Part 1

    - by Sahil Malik
    SharePoint 2010 Training: more information Hooray! My latest article is now online on code-magazine. And this time, it’s about “Workflows in SharePoint 2013” – and there will be a part 2 of this next month. Here is a starter .. If we have been friends for a while, you must know my opinions about workflows in SharePoint 2010 and SharePoint 2007. I didn’t think they were very good, especially from a performance and scalability point of view. Frankly I think Microsoft should have called them “workslows.” Though, I don’t think it was the implementation in SharePoint that was the issue, it was fundamental issues with Workflow Foundation, compounded by the nature of SharePoint that acerbated the issues. Well, I am happy to say that Workflows in SharePoint 2013 are something I feel quite comfortable recommending to anyone, and I hope to make that case in this article. Read more ..

  • How to efficiently preserve a really big navigation history in Firefox?

    - by brandizzi
    When I was using Mac, my Firefox stored items in its history for really long times. Sometimes I needed to find a link to a site I have seen two years ago and it found it! Also, the autocomplete in the Firefox bar is really great, so a long history and the autocompleting yield a wonderful feature to me. Unfortunately, it seems this does not happen in Ubuntu's Firefox. I looked for solutions but I just got some Firefox developers saying the option of expanding history is out for performance issues and one is well advised to not try to change it (which read to me as saying "we cannot make it work well so we limit the scope"). Anyway, my question is: is there a way of efficiently expand the size of Firefox history? Sorry for my bitterness, but a solution with strings attached (mostly say that I should not do it, like this addon) is not solution for me. Does someone have the same need of mine and found a solution?

  • Curious about a cached old domain

    - by jogesh_p
    I am a bit curious about my new domain. I had a domain before, let's say http://example.com/. Before expiration of that domain, I bought a new one with the name http://another-domain.com/. I uploaded all of my content on the second domain, but now when I search in Google about some query related to my http://another-domain.com/ site then I also find my old domain in the results. Will this give a duplicate content error for my new domain or any other kind of penalty from Google?

  • Need assistance for domain forwarding

    - by Yusuf Andre
    Briefly my question is about combining my registered domain with the websites listening on port 80/8080 on my server. I have a web server IIS on windows 7 and two web sites listening on port 80 and 8080. I have successfully forwarded any incoming request to port 80 and 8080 to my web server. So everything works like a charm when I try to access these websites entering http://myglobalip:80/Index.aspx or http://myglobalip:8080/Index.aspx from a computer outside of the local network. So I have a domain registered, lets say www.mydomain.com. What steps should I follow in which sequence? What should I consider to do? I need a step by step guide to follow. I have registered my domain on godaddy's website and only configured forwarding so the domain forward to my webserver but when I attempt to access the web page, It always try and try until It times out.

  • Dynamic Tab Implementation in ADF

    - by Vijay Mohan
    Well, this can be a common usecase across apps to open tabs dynamically at runtime based on the request.Well, in order to achieve this you can have a parent container, lets say a panelTab component.Inside panelTab , u can have a showDetailItem inside an af:foreach or an af:iterator binded to a bean static list which will have as many show detail items as you wish to be shown.something like this.private static List = { new showDetailItem("1"),new ShowDetailItem("2") ...};now in the backing bean you can have a method that takes care of rendering and disclosing an specific tab based on the index.public void openMyTab(){List<MyItems> list = refToParentContainer.getChildren();int indexOfTabToBeOpened = //Write a method that will compute the tab index of the next //tab.list.get(index).setRendered(true);list.get(index).setDisclosed(true);similarly you can set other properties too.}Else, instead of having af:foreach/iterator iterating through the SD items , you can go for static SDs in the page with render property set to false and then you can follow the same approach to render/disclose it at runtime.

  • Using heavyweight ORM implementation for light based games

    - by Holland
    I'm just about to engulf myself in an MVC-based/Component architecture in C#, using MySQL's connector/Net for the data storage, and probably some NHibernate/FluentNHibernate Object-relational-mapping to map out the data structure. The goal is to build a scalable 2D RPG. Then I think about it...and I can't help but think this seems a little "heavy weight" for a 2D RPG, especially one which, while I plan to incorporate a lot of functionality and entertaining gameplay, may be ported to something like Windows Phone or Android in the future. Yet, on the other hand even a 2-Dimensional RPG can become very complicated, and therefore must incorporate a lot of functionality. While this can be accomplished with text/XML/JSON for data storage, is there a better way? Is something such as Object-Relational-Mapping useful in such an application? So, what do you think? Would you say that there is a place for such technologies? I don't know what to think...

  • Sound Juicer doesn't respect Lame's codec settings when ripping CDs

    - by Takkat
    Using Sound Juicer I am able to rip CDs very conveniently. I would like to rip them in about 256 kbit/s variable bitrate. To accomplish this I have defined the settings for mp3 in gnome-audio-profiles-properties as follows: audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=0 vbr-quality=0 ! id3v2mux where vbr-quality=0 should give me a variable bitrate averaging 245 kbit/s. The resulting files however always say they are in 128 kbit/s. Is this only a tagging bug or is indeed the bitrate that low? How could I find out?

  • The fallacies of all these Studies Linking one thing to another&hellip;

    - by Shawn Cicoria
    Are pesticides really the link?  Or is it hereditary?  Pesticides in kids linked to ADHD http://www.msnbc.msn.com/id/37156010/ns/health-kids_and_parenting/ You’ve got to think this one through.  If the parents already have ADHD, and they buy fruits, don’t have the “patience” to wash the fruit, and the kids end up with larger detectible amounts of pesticides in their bodies – are the pesticides really the cause or is it hereditary? I say, switch the kids around for the real test – sure, let the kids go live at a parent’s house w/ out ADHD for 10 years [clearly I’m kidding] who then consciously chooses NOT to wash the fruit. I read this story and all I could think was that the parents already have ADHD and they end up not washing these fruits and vegetables

  • Is dynamic casting Entities A good design?

    - by Milo
    For my game, Everything inherits from Entity, then other things like Player, PhysicsObject, etc, inherit from Entity. The physics engine sends collision callbacks which has an Entity* to the B that A collided on. Then, lets say A is a Bullet, A tries to cast the entity as a player, if it succeeds, it reduces the player's health. Is this a good design? The problem I have with a message system is that I'd need messages for everything, like: entity.sendMessage(SET_PLAYER_HEALTH,16); So that's why I think casting is cleaner.

  • Oracle WebCenter at the Enterprise 2.0 Conference

    - by Brian Dirking
    We had a great week at the E20 Conference, presenting in four sessions – Andy MacMillan gave a session titled Today’s Successful Enterprises are Social Enterprises and was on a panel that Tony Byrne moderated; Christian Finn spoke on a panel on Unified Communications Unified Communications + Social Computing = Best of Both Worlds?, Mark Bennett spoke on a panel on The Evolution of Talent Management. The key areas of focus this year were sentiment analysis, adoption and community building, the benefits of failure, and social’s role in process applications. Sentiment analysis. This was focused not on external audiences but more on employee sentiment. Tim Young showed his internal "NikoNiko" project, where employees use smilies to report their current mood. The result was a dashboard that showed the company mood by department. Since the goal is to improve productivity, people can see which departments are running into issues and try and address them. A company might otherwise wait until the end of the quarter financials to find out that there was a problem and product didn’t ship. This is a way to identify issues immediately. Tim is great – he had the crowd laughing as soon as he hit the stage, with his proposed hastag for his session: by making it 138 characters long, people couldn’t say much behind his back. And as I tweeted during his session, I loved his comment that complexity diffuses energy - it sounds like something Sun Tzu would say. Another example of employee sentiment analysis was CubeVibe. Founder and CEO Aaron Aycock, in his 3 minute pitch or die session talked about how engaged employees perform better. It was too bad he got gonged, he was just picking up speed, but CubeVibe did win the vote – congratulations to them. Internal adoption, community building, and involvement. On this topic I spoke to Terri Griffith, and she said there is some good work going on at University of Indiana regarding this, and hinted that she might be blogging about it in the near future. This area holds lots of interest for me. Amongst our customers, - CPAC stands out as an organization that has successfully built a community. So, I wonder - what are the building blocks? A strong leader? A common or unifying purpose? A certain level of engagement? I imagine someone has created an equation that says “for a community to grow at 30% per month, there must be an engagement level x to the square root of y, where x equals current community size, and y equals the expected growth rate, and the result is how many engagements the average user must contribute to maintain that growth.” Does anyone have a framework like that? The net result of everyone’s experience is that there is nothing to do but start early and fail often. Kevin Jones made this the focus of his keynote. He talked about the types of failure and what they mean. And he showed his famous kids at work video: Kevin’s blog also has this post: Social Business Failure #8: Workflow Integration. This is something that we’ve been working on at Oracle. Since so much of business is based in enterprise applications such as ERP and CRM (and since Oracle offers e-Business Suite, Siebel, PeopleSoft, and JD Edwards, as well as Fusion Applications), it makes sense that the social capabilities of Oracle WebCenter is built right into these applications. There are two types of social collaboration – ad-hoc, and exception handling. When you are in a business process and encounter an exception, you immediately look for 1) the document that tells you how to handle it, or 2) the person who can tell you how to handle it. With WebCenter built into these processes, people either search their content management system, or engage in expertise location and conversation. The great thing is, THEY DON’T HAVE TO LEAVE THE APPLICATION TO DO IT. Oracle has built the social capabilities right into the applications and business processes. I don’t think enough folks were able to see that at the event, but I expect that over the next six months folks will become very aware of it. WebCenter also provides the ability to have ad-hoc collaboration, search, and expertise location that folks need when they are innovating or collaborating. We demonstrated Oracle Social Network. It’s built on our Oracle WebCenter product to provide social collaboration inside and outside of your company. When we showed it to people, there were a number of areas that they commented on that were different from the other products being shown at the conference: Screenshots from within the product Many authors working on documents simultaneously Flagging people for follow up Direct ability to call out to people Ability to see presence not just if someone is online, but which conversation they are actively in Great stuff, the conference was full of smart people that that we enjoy spending time with. We’ll keep up in the meantime, but we look forward to seeing you in Boston.

  • Successful technical communities except for open-source?

    - by Joshua Fox
    Have you ever seen a successful technical community -- e.g. user group, industry organization? Am I asking about a group of software engineers who get together F2F (or maybe online) and discuss technical and industry issues with deep zeal and interest -- a place where meaningful connections are made. Here are the only examples I have ever seen: Open source Maybe the Silicon Valley Java Users' Group Homebrew Computing Club in the '70's This sort of thing does exist in academia. Of course, there are lots of conferences and attempts at user's groups. However, almost all committed, serious software engineers, when asked about this, say "I don't have the time", which means that the organizations are not worthwhile to the best in our profession. Has anyone seen any organizations with an ongoing spirit of enthusiasm from top software engineers?

  • Should a view and a model communicate or not?

    - by Stefano Borini
    According to the wikipedia page for the MVC architecture, the view is free to be notified by the model, and is also free to query the model about its current state. However, according to Paul Hegarty's course on iOS 5 at Stanford, lecture 1, page 18 all interaction must go through the controller, with Model and View that are never supposed to know each other. It is not clear to me if Hegarty's statement must be intended as a simplification for the course, but I am tempted to say that he intends the design as such. How do you explain these two opposite points of view ?

  • If Scheme is untyped, how can it have numbers and lists?

    - by Dokkat
    Scheme is said to be just an extension of the Untyped Lambda Calculus (correct me if I am wrong). If that is the case, how can it have Lists and Numbers? Those, to me, look like 2 base types. So I'd say Racket is actually an extension of the Simply Typed Lambda Calculus. No? Question: Is Scheme's type system actually based or more similar to Simply Typed or Untyped Lambda Calculus? In what ways does it differ from Untyped and or Simply Typed Lambda Calculus? (The same question is valid for "untyped" languages such as Python and JavaScript - all of which look like they have base types to me.)

  • Closest location - Heapify or Build-heap

    - by Trevor Adams
    So lets say we have a set of gps data points and your current location. If asked to give the closest point to your current location we can utilize a heap with the distance being the key. Now if we update the current location, I suspect that only a few of the keys will change enough to violate the heap property. Would it be more efficient to rebuild the heap after recalculating the keys or to run heapify (assuming that only a few of the keys have changed enough). It is assumed that we don't jump around with the new location (new current location is close to the last current location).

  • How do I get Unity working again after installing the wrong video driver?

    First off I did something stupid. I downloaded a Nvidia driver even though I have an integrated chipset. After installation my unity was still working. However, when I restarted my computer I got an error message saying that I can't run unity. I uninstalled the Nvidia driver. I restarted my computer. Unity still does not work. In the terminal I type "unity" and everything looks okay until I get three error messages that say this: Xlib: extension "GLX" missing on display ":0.0". followed by: Compiz (opengl) - Fatal: glXCreateContext failed Compiz (bailer) - Info: Ensuring a shell for your session jesse@jesse-PC:~$ Cannot register the panel shell: there is already one running.

  • Can I get any logging and error output from Flash?

    - by Dave M G
    To further provide better information for my other question about browsers and Pulse audio, I wanted to see if I could get some kind of helpful log information. I've looked at logs from both Pulseaudio and Firefox, but don't see anything like an error in either of them. The problem I'm experiencing may be coming from Flash. Is there a way I can trap specifically any log output from Flash? Update: I've downloaded the Linux Flash Player 10.3 Plugin content debugger, and I've installed libflashplayer.so in ~/.mozilla/firefox/plugins/, and copied the user/* files to /user. I've also set up mm.cfg to say: ErrorReportingEnable=1 TraceOutputFileEnable=1 MaxWarnings=50 TraceOutputFileName=/home/dave/.macromedia/Flash_Player/Logs/flashlog.txt And I rebooted just to be sure everything was starting fresh. However, after playing a Flash video from Youtube, flashlog.txt is not being generated. How can I be sure that logging is in fact enabled, so I can tell whether I'm simply not getting errors or I haven't set up logging correctly?

  • Stupid Geek Tricks: How To Download Firefox On a New Computer Without Using Internet Explorer

    - by Chris Hoffman
    Internet Explorer-haters often say that the only good use for Internet Explorer is downloading Firefox or Chrome. But if you really don’t like IE, you can use Windows’ built-in FTP support to download and install Firefox without ever opening IE. Sure, you could just open Internet Explorer and download Firefox from Mozilla’s website, but where’s the geeky fun in that? This trick is about Firefox because Mozilla provides an FTP server, while Google doesn’t seem to.
