  • Collision for mobile game

    - by zemiguel12
    I'm writing a little game in as3 using Starling, and I need to check collision between 2 boats that can rotate. I don't need the pixel perfect collision, but bounds collision is not enough too. The boat look more or less like this: I was thinking about create one square on the back of the boat and a triangle on the front, than for each boat, check if the square collide with the other boat square or triangle, and the same for the triangle. I just don't know how to do that, I don't know if it's possible with the Shape.hitTest, or if it's the best way to do that. What can I do?

  • Encouraging business and team members to write more code

    - by Aliixx
    I am really interested to hear any ideas or working practices that can be adopted to encourage our team of developers to write more code. A little background here is involves a team of varying disciplines, experience and qualities and the nature of the work has a large focus on bug fixes and business logic / data validation over writing lots of new greenfield code or even refactoring. We are attempting to move to a more Agile philosophy and really what would be great is to hear any ideas that can be sold to the team and / or the business with the aim of: Writing more new code to improve experience, abilities and increase exposure to newer and emerging patterns and practices. Energizing the effort of the team and inspire. Encouraging wider input of new ideas, patterns and practices from the team as a whole. I would be very interested (and grateful) to hear any ideas or examples of ideas that can help here. Thanks!

  • What is the "don't force full gpu scalling" configuration in the newest Nvida driver settings?

    - by wild_oscar
    I have a Zotac Ion board on a computer running Linux ad I had the driver version 295.xx. I was trying to run a 1080 video on XBMC and, because playback was a bit sluggish, part of my (unsuccessful) attempt at making it run smoothly was to upgrade the Nvidia driver. The problem is that the computer is connected by HDMI to a Pioneer A/V system - which in turn is connected to the TV (also through HDMI). When I created this set up I didn't get any image on my tv until I Unchecked "force full gpu scaling" in "Flat Panel Scaling". After upgrading the Nvidia driver I no longer have image. Upon investigating, I saw on the release changelog: Removed Flat Panel Scaling configurability in nvidia-settings. Any desired scaling can be configured through the new "ViewPortIn" and "ViewPortOut" MetaMode attributes. I know very little about this, however, so I'm lost. What would the correct configuration be with these new ViewPortIn/Out options to achieve the same result as "unchecking force full gpu scalling"?

  • Running the Ubuntu Kernel and OS on custom processor

    - by xupv5
    This is hardly a theoretical question as many have done this, albeit there's very little information on the underlying processes. I'm developing a custom MIPS-based processor on which I would like to run ubuntu. I'm quite baffled as to what to do next after you've designed the instruction set and the computer architecture itself. I need to be able to run a kernel and OS but how does it all tie in? At the moment I'm researching into designing a compiler for the linux kernel to generate the appropriate assembly language. Is that a good way to go? What do I need to do after that?

  • Second monitor stopped working

    - by Mark D
    After setting up 11.10 today, I seem to be having problems with my dual monitor set up. It worked without issues in Mint but today after I switched to 11.10 only one monitor seems to function. This seems a little odd to me. During setup both monitors functioned without issue, although they were mirroring each other both monitors but as soon as it booted into Unity my secondary monitor stopped working. I checked under settings-display and the second monitor doesn't seem to even be detected. On the off chance it had something to do with drivers, I upgraded the proprietary drivers to the latest version with zero success. If anyone has any ideas, I'd love to hear them.

  • Any tips/tricks/resources on actually TEACHING a class on OOP? [closed]

    - by Sempus
    I may slowly be getting into teaching an Object-Orientated Programming class at my school in a year or two. I just graduated and work at my school as an Application Programmer. I'd first start off as a TA/grader and then slowly move into the Professor role. The class would be in Java. I always see resources on this fine site about HOW to program, but does anyone know any tips/tricks/resources on how to TEACH a programming class? It would be full of all different skills levels(but still semi-technical) so it would have to be a little more understandable than if it was just CS kids.

  • Where can I get the 10k common English dictionary words which Stack overflow uses in related question? [migrated]

    - by itpian.com
    Where can I get the 10k common English dictionary words which Stack overflow uses in related question? Here in SE podcast - http://blog.stackoverflow.com/2008/12/podcast-32/ One of our major performance optimizations for the “related questions” query is removing the top 10,000 most common English dictionary words (as determined by Google search) before submitting the query to the SQL Server 2008 full text engine. It’s shocking how little is left of most posts once you remove the top 10k English dictionary words. This helps limit and narrow the returned results, which makes the query dramatically faster.

  • How can I disable as much "flair" as possible in Unity?

    - by UlfR
    I'm running Ubuntu 11.10 from a fresh install on a somewhat aged computer, so I have some speed problems. But since I do want to use the new cool way to work with things that Unity introduces I do not want to fiddle with getting another desktop environment. My idea is to disable as much flair as possible, but there are tonnes of options that I do not understand or have the time to read up on when I launch CompizConfig Settings Manager. Which of these could safely be disabled? Are there other places where performance could be gained by disabling things? So how can I make the whole thing a little more snappy?

  • Ubuntu 12.04 ATI 6450

    - by user210717
    Right now my video card isn't responding after the Ubuntu Logo is shown, (I see a black screen and that's it) I have installed ubuntu 12.04 AMD64 and if I remove the video card and use the VGA from the MOBO then I can use it with no problems, other data: 4 GB of ram 1333 500 GB WD AMD APU A6 3500 2,1 GHZ I forgot a couple of details, everything was working great until last night, when the light went off (I don't know if I'm explaining myself I'm from Argentina and english isn't my first language there was a power cut I meant) and then when it got back I used my pc until I went to bed (after upgrading) and this morning, when I woke up I had this problem for breakfast, I've been reading a little and I had a similar problem before and fixed it, but it was a system problem, a missing package or something, I don't remember, but here the only issue is that the video card doesn't give me image after the ubuntu logo.

  • Advise how to write a simple test for this javascript snippet?

    - by resting
    I'm trying to start unit testing (not using any testing frameworks) for my javascripts. Here's one example of it. var obj = {}; obj.disableBtn = function ($btn, style) { $btn.attr('disabled','disabled').addClass('disabled').removeClass(style); }; The use case is as such: obj.disableBtn($('.submit'), 'btn-blue'); What it does is simply add the disabled attribute, add the disabled class, and remove the btn-blue style. Please advise how would a typical test case look like in this case. I have a little knowledge on testing using assert(), but have no idea how to go about it when it involves verifying the result on HTML elements.

  • Can Tutorial "Dual Boot Windows 7 & Ubuntu 12.04" Used for Dual Booting Windows 8 & Ubuntu 12.10?

    - by Shyuan
    I previously used this tutorial to dual boot Windows 7 and Ubuntu 12.04 perfectly. Now I have upgraded my Windows 7 to Windows 8. And I would like to do a fresh install (and start all over again like the tutorial) of Ubuntu 12.10 replacing existing Ubuntu 12.04. I like the way the tutorial presents thus can anyone kindly let me know if the tutorial is compatible with what I wanna do now? I have tried doing little research whether this has been asked, but all I got are not too similar to my question, if there are topics like this I do apologise and feel free to close it. Hope to hear from the community. Thank you so much. :)

  • Turn Off Sleep on Seagate GoFlex?

    - by RPG Master
    I bought this 2tb Segate GoFlex this last Black Friday and since then every 15 minutes or so the drive spins down, and then a little while later completely dismounts. Very annoying. From what I understand you could turn this off using the including Windows and Mac only software. This function and what controls it isn't proprietary, right? There has to be something that'll let me set it in Ubuntu... Anyone have any suggestions? Also, I formatted it to EXT4. Hope I didn't screw myself up. :/

  • Where to upload my small apps or codes

    - by user108386
    My question is simple, but I couldn't found a good answer to it. Where to upload my code and my apps? I searching for a place where people find them. Homeworks, hobby projects, little helper scripts, and other open-source stuff. Does it depend on the used technology? I know, there are a lot of subversioning and project hosting systems. But where to start? I don't really know what I'd like. Maybe a wiki-post in the topic with paragraphs like: Upload you open source Winforms app to somesite or If you want to develop a Java library with your friends , use someothersite or Freeware stuff's best place is: ...

  • How can I avoid the engineering mistakes of PDT?

    - by ashy_32bit
    As a developer with enough experience to evaluate a tool, I may say that PDT is very huge in size and slow in performance for a PHP IDE. It gets bigger by release and exponentially slower by the size of the projects. Add some extra syntax coloring rules and it literally crawls, code completion works randomly and building workspace takes like forever. Java black magic (-Xmx etc) eases the pain a little but that's it. So my questions are: Why is PDT like this? What design or engineering factors led to its poor performance? How can I avoid making these same mistakes in my own products?

  • When going for an interview for web development at an agency, can a real example be expected?

    - by KPO
    I just started coding a year ago. By "coding" I mean HTML(5), CSS(3), and only a few times I implemented AJAX and JavaScript. I am interviewing for a position that expects me to know HTML, CSS, JS, JQuery, and AJAX. I am good with HTML5/CSS3 and somewhat ok with js. If I go for an interview, will they expect me to write code during the interview? I do have a live website as an example and snapshots of past projects that I sent to them. I am a little nervous, so any tips or something from your experience I can learn will be helpful.

  • Working alone vs with others

    - by tmewett5
    Being a student in a small school, there aren't a lot of people (well, there aren't any) that share the same passion or skill of programming that I have. I have been learning to program myself since the age of 9, and I believe I have reached the level where I am ready to do something more ambitious, as opposed to the little scripts and personal web design I do at the moment. The point is: would having a small group - or just another person - allow us to achieve greater things? If so, how would I begin building a team?

  • Samba login before requesting list of shares?

    - by user69359
    I'm relatively inexperienced at this and am starting to get a little frustrated: I have a Ubuntu Server with several user accounts. The Samba file server hosts a number of public shares + the home directories of each user as a private share. When connecting to the server using my OSX machine, I am prompted to enter my login data, and get a overview of all the public shares + my accounts home directory share. Exactly the way I want it. How ever, when I connect to the server from a Ubuntu machine, I am never prompted to enter any login data, and can only see the public folders. If a user wants to connect to their home directory on the server, they have to go through "connect to server" and mount their specific private share. Is there anyway to configure Samba or the Ubuntu client in a way that will make the user experience more similar to how it is on my OSX box? Thank you for your time!

  • Large Sprite Performance

    - by Iansen
    I've got a large Sprite generated using a set of vertices(x,y coordinates) and a bitmap pattern (using moveTo, lineTo, beginBitmapFill, endFill ...etc). It's about 15000 pixels wide and between 1500 - 2000 pixels high depending on the level -it's the terrain for a 2D game. My question is: what is the best way to display/move it on the stage - performance wise? Currently I'm just adding it to the stage as is...I get decent frame rate/ memory/ cpu usage but I want to optimize it for slower PCs. Any ideas? I've been reading a little about blitting but I'm not sure how to implement it in my case. Thanks.
