  • Cocos2d and Body with few collision shapes using chipmunk

    - by Eimantas
    I'm using Cocos2d (0.99.5) with chipmunk physics engine. Currently I'm trying to place a body into space which is combined from few circle shapes. Let's say I have a corresponding sprite image with displays atom (nucleus + 3 electrons around it. Something like this without orbit lines). In it's simplest form - only one circle shape at the center should be enough which would detect collisions from other objects with nucleus. Now I'd like to add other circle shapes for each electron. How can I do that? Now when I add those shapes to the body and add the body into chipmunk space - the shapes (together with the body/sprite) start flickering and spinning with no recognizable pattern (or reason for that matter).

  • Computer vision algorithms (how is this possible?)

    - by Maxim Gershkovich
    I recently stumbled across a company that has created what appears to be a computer vision technology that is capable of detecting shoplifting automatically and alert its users. LINK Watching some of the videos and examples provided by the company has left me completely baffled and amazed as to how on earth they may have achieved this functionality. I understand that no-one here will be able to tell me exactly how this may have been achieved but is anyone aware - and could point me to - research in this field or alternatively perhaps provide details as to how something like this could be implemented or guidance of where one might start? My understanding was the computer vision algorithms were many years away from being this sophisticated. Is this sort of application really possible? Anyone willing to hazard a guess at how they achieved this?

  • How to get exfat working in Ubuntu 13.10?

    - by davorao
    In Ubuntu 13.04 there was an option to use the PPA by Relan in order to get ExFat functionality. Seeing that in Ubuntu 13.10 this functionality is available from the repositories without the PPA I tried this but failed to make it work. Trying the PPA in Ubuntu 13.10 does not yield results either, as it complains about missing the fuse-utils package. This package seems to have been removed (https://launchpad.net/ubuntu/saucy/amd64/fuse-utils). So my question is, did the process of using ExFat change since the jump from Ubuntu 13.04 to 13.10 and how do I enable it? Old Way sudo apt-add-repository ppa:relan/exfat sudo apt-get update sudo apt-get install exfat-fuse exfat-utils Tried now via Ubuntu Software Center sudo apt-get install exfat-utils exfat-fuse

  • Best questions to ask a startup founder, CTO, or CEO

    - by YGomez
    This is not a duplicate of this SE post. Most questions of this sort center around an interview experience. I want questions that you might be genuinely interested in, even if they are not at all appropriate to ask during a job interview. If you have read the book Founders at Work, that is the kind of question I am talking about. So I guess, what would you ask if you were interviewing them? I am specially interested in questions that might give a possible future startup founder insight.

  • ATI Catalyst doesn't retain changes after reboot when setting extended display

    - by rfc1484
    I have Ubuntu 11.10 and I'm trying to set up extended display for my two displays. I have an AMD 6870. fglrx and fglrx-updates are installed. When I launch amdcccle trough the terminal (using sudo), I select in tab "Multi-Display" the option "Multi-display Desktop with Display(s)". Then it says for changes to be done I have to reboot my computer. Being a good an obedient lad I do just that, but after rebooting the displays are still in the same "clone" option as before in the Catalyst Control Center and no changes are made. Any suggestions?

  • HTML5 or Native Android/iOS application?

    - by Dimitris
    I would like to hear your opinion on this debate. I want to build a mobile application which will interact with a server and I was wondering what's the best way to do it. Build the entire application using the HTML5 technology and then just create native "browsing" apps for Android/iOS or to build the Android/iOS apps from scratch? Using the HTML5 will save considerable amounts of time but I don't know if the result will be equally good in both platforms. Building native apps will take much more time but the result will be definitely good. What do you think?

  • Creating your First Crystal Report for Use in a .NET Application

    Have you ever had to create a custom report within an application you have written for a customer? Most developers have, and there are two schools of thought on how developers normally perform this task. Some choose to create the report using the same technology that the application was created in (ASP, WinFrom, WPF) while others choose to use a reporting package such as Crystal Reports. Using a reporting package will help create reports rapidly. This article walk you through the creation of your first report using Crystal Reports.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Why Adobe Air is so underrated for building mobile apps?

    - by Marcelo de Assis
    I worked with Adobe Flash related technologies for the last 5 years, although not being a big fan of Adobe. I see some little bugs happening in some apps, but I cannot imagine why a lot of big companies do not even think to use use Adobe Air as a good technology for their mobile apps. I see a lot of mobile developer positions asking for experts in Android or iOS , but very much less positions asking for Adobe Air, even when Adobe Air apps have the advantage of being multi-plataform, with the same app working in Blackberry, iOS and Android. Is so much easier to develop a game using Flash, than using Android SDK, for example. It really have flaws (that I never saw) or it is just some kind of mass prejudgement? I also would like to hear what a project manager or a indie developer takes when choosing a plataform for building apps.

  • Is SharpDX mature enough to adopt yet or should I just start using SlimDX right now?

    - by Gavin Williams
    I'm about to stop my game-project in XNA because from what I can gather it's development is coming to an end (and it's already behind current technology). Therefore, I need to adopt a new framework or API. I have just spent 2 days looking at C++ and decided it's really not for me - however I do find the raw access to DirectX appealing. SharpDX sounds like a good place to start, but it has no documentation and no code comments. I feel like it's not quite ready for use. I'm interested in the opinions of people that have used either or both of these frameworks, to help me decide for sure which one I should learn? Thanks for any advice.

  • The Customer Experience Imperative: A Game Changer for Brands

    - by Jeri Kelley
    By Anthony Lye, SVP, Cloud Applications Strategy, Oracle We know that customer experience has emerged as a primary differentiator for businesses today.  I’ve talked a lot about the new age of the empowered consumer. At Oracle we’ve spent a lot of time developing technologies and practices that our customers can implement to greatly improve their customer experience strategies. Of course I’m biased, but I think that we have created a portfolio of the best solutions on the planet to help organizations deal with the challenges of providing great customer experiences. We’ve done this because we started to witness some trends over the last few years. As the average person began to utilize social and mobile technologies more frequently and products commoditized, customer experience truly remained the only sustainable differentiator for businesses.In fact, we have seen that customer experience is often driving the success or the failure of a product or a brand. And as end customers have become more vocal about their experiences with companies on social and mobile channels, they now have the power to decide which brands will win and which brands will lose. To address this customer experience imperative, I believe that business today must do three things really well:Connect with your customers. You have to connect with customers whenever, wherever and however they want. Organizations must provide a great experience on their existing channels— the call center, the brick and mortar store, the field sales organizations, the websites and social properties. Businesses must also be great at managing and delivering journeys on these channels, while quickly adapting to embrace the new channels that emerge. You have to understand mobile. You have to understand social. You have to understand kiosks. These are all new routes to market, new channels where your customers may or may not show up. You have to interact with them where they are. You have to present information in a way that's meaningful to them. As well as providing what we would call a multichannel experience. We have to recognize that customers may start their experience on one channel, but end it on a different channel. It’s important that an organization’s technology solutions enable, not just a multichannel strategy, but a strategy that can power new channels and create customer journeys that cross these channels.Get to know your customers. Next, companies need to get to know the customer as intimately as the customer will allow. Today most customer interactions are anonymous, but it’s important for brands to know which customers drive value. Customers want to provide feedback. They want to share their opinions, but they want to know that those opinions are being heard and acted upon. For this to occur, we need to know much more about the customer and then reward them for their loyalty and for their advocacy.Enable connections. The last thing is to enable people to connect or transact with your brand. We've got to make it really, really simple for customers to do business with us. We can't make them repeat the steps; we can't make them tell us their identity for the fifth time as they move between organizations. These silos can no longer sustain or deliver a good customer experience. It's extremely important that companies be where customers want them to be—that we create profitable journeys for us and for them.Organizations have to make sure that there is a single source of truth that defines the customer. We have to make sure that the technology applications that we rely on understand not just the dimensions of multichannel, but of cross-channel too. We have to enable social at the very core of the overall architecture. We have to use historical analytics, real-time decisioning as well as predictive analytics to help personalize and drive an experience. And these are all technologies that IT needs, that IT is familiar with, but needs to enable for the line of business that in turn can enable for the end customer.  This means that we've got to make our solutions available to the customers in the cloud.In this new age of the empowered consumer, businesses have to focus on delivery mechanisms that reduce the overall TCO, while driving a rapid rate of innovation and a more rapid rate of deployment. At the Oracle Customer Experience Summit @ OpenWorld, I’ll discuss these issues and more. I hope that you can join us for what promises to be an unforgettable experience.

  • Syncing my iPod Touch (And Others)

    - by Benjamin Hannah
    libimobiledevice doesn't work for me. I've got Ubuntu 11.10 and I'm trying to put music on to my iPod Touch 4Gen running iOS 5.0.1. I have tried every program available in the Ubuntu software center for sycing iPods and I get basically the same response from each one: "[cannot apply changes etc, ect, etc]" I've tried rigorously with Banshee and Rythmbox with no success. I've even tried running iTunes on Windows XP in VirtualBox with no success. I've tried running iTunes through Wine and it results in an error message saying something along the lines of "[Please install Apple Application Support and then reinstall iTunes]". I am considering Jailbreaking my iPod but I cannot find Absinthe that works with my iPod and with Ubuntu. In addition I'm not sure how ** works with Ubuntu. I'm really in a pickle here. It would be ever so helpful if I could indeed have some help with this issue.

  • Beyond Syntax Highlighting - What other code representations are possible today?

    - by Mathieu Hélie
    Despite GUI applications having been around for 30ish years, software is still written as lines of text instructions, for various valid reasons. But we've also found that manipulating these text instructions is mind-blowingly difficult unless we apply a layer of coloring on different words to represent their syntax, thus allowing us to quickly parse through these text files without having to read the whole words. But besides the Sublime Text minimap feature, I've yet to see any innovation in visual representation of code since colors came around on CRT monitors. I can think of one obviously essential representation that modern graphics technology allows: visual hierarchies for nested structures. If we make nested text slightly smaller than its outer context, and zoom on it when the cursor is focused on the line, then we will be able to browse huge files of nested statements very quickly. This becomes even more essential as languages based on closures and anonymous functions become filled with deep statements. Has anyone attempted to implement this in a text editor? Do you know of any otherwise useful improvements in representing code text graphically?

  • Setting Anchor Point

    - by Siddharth
    I want to set anchor point for the sprite like cocos2d has done for their implementation. I do not found any thing like that in andengine so please provide guidance on that. I want to move the sprite on touch so I use following code but that does not work for me. super.setPosition(pX - this.getWidthScaled() / 2, pY - this.getHeightScaled() / 2); Because I touch on the corner of the image but automatically it comes at center of the image because of above code. I want to remain the touch at desire position and drag it. For me the anchor point became useful. But I don't found anything in andengine.

  • Customising Google Maps breaks highway label blocks

    - by user2248809
    I'm trying to customise a Google map to use shades of a particular colour. It's working nicely except the blocks that contain major road names / numbers is illegible. I've figured out how to target styles to those elements, but setting the 'color' value sets both text and background to that colour. And no adjusting of saturation, gamma, lightness etc seems to make the text legible. function initialize() { var latlng = new google.maps.LatLng(50.766472,0.284732); var styles = [ { stylers: [ { "gamma": 0.75 }, { "hue": "#607C75" }, { "saturation": -75 }, { "lightness": 0 } ] },{ featureType: "water", stylers: [ {color: "#607C75"} ] } ]; var myOptions = { zoom: 15, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP, }; var marker = new google.maps.Marker({ position: latlng, title:"Living, dining, bedrooms by David Salmon" }); var map = new google.maps.Map(document.getElementById("map"), myOptions); map.setOptions({styles: styles}); marker.setMap(map); }
