  • Read video from dvd in RAW filesystem

    - by kpinhack
    Hallo, i've got some dvds that were recorded on a dvd recorder. I can not read those dvds on windows PCs (i tried multiple PCs). The properties of the discs say that the filesystem of the disc is RAW and i think that is the reason why windows does not read the disc. If that is true, what can i do to read the dvds ? Or what else could be the problem ? EDIT: The windows PCs i tried play back regular DVDs without any problem, and the "RAW" dvds recorded with the dvd recorder will not play on a standalone dvd player. Thank you!

  • Editing sudoers file to restrict a user's commands

    - by devin
    Is it possible to edit the sudoers file so a user can use sudo for any command except for a specified one? I reverse is true, I believe, that the sudoers file can be setup so that a user can only execute a given list of commands. EDIT: the commands I really want to take away are halt and reboot... this makes me think there are special system calls for halt and reboot. Can you take system calls away from a user? If not, is it because the unix permission system abstracts over system calls neglecting this?

  • Repairing The Visual Studio 2012 UI

    - by Ken Cox [MVP]
    I have sympathy for ‘Softies who don’t like the controversial ‘Metro’ UI changes but are afraid to say so. After all, who wants to commit a CLM (Career-Limiting Move) by declaring that the Emperor has no clothes (or gradients) and that ALL CAPS IN MENUS ARE DUMB? Talk about power! Here’s a higher-up (anyone got a name?) who has enforced a flat, monochrome, uninteresting user interface in Visual Studio 2012  that has been damned with faint praise by consumers. The pushback must have been enormous. Some ‘Softies disengage from the raging debate with, “It’s not my decision” while others feebly point out that the addition of some colour pixels in the icons is a real improvement over the beta version. True, I guess. With the UI pretty much locked, its down to repairing the damage. Fortunately, some Empire dissident has leaked the news to a blogger that  those SHOUTING CAPs aren’t hardcoded afterall: How To Prevent Visual Studio 2012 ALL CAPS Menus And so it goes. By RTM, I’m sure there will be many more add-ons to help us ‘de-Metro’ VS 2012 and recreate our favourite Visual Studio 2010 themes for it.

  • Why did cherokee-admin-launcher crash?

    - by DarenW
    I'm trying out the Cherokee http server on a seemingly fine machine. Following simple set-up instructions, I tried running cherokee-admin-launcher but it printed error messages and hung up.

    After I have installed Ubuntu 12.04 LTS (32 bits), Firefox 12 works fine but without hardware acceleration. Needless to say I have the latest nVidia's proprietary drivers installed and my Firefox Preferences, on "Advanced" tab, "Browsing" section, have the option "Use hardware acceleration when available" checked. I have tried the following things before asking this question: Creating a boolean key "webgl.force-enabled" and set it to true on Firefox's page about:config; Starting a new profile like commented on thread Mozilla Firefox 12 is very slow on Ubuntu 12.04 LTS; I have updated my nVidia driver to version 295.53.

  • Lexmark X5650 doesn't print (scanning works)

    - by unor
    I want to use a Lexmark X5650 under Ubuntu. When I connect it via USB, Ubuntu recognizes the device, but can't find a driver. On the Lexmark support site, you can select "Unix/Linux" and then "Ubuntu 9.04", "9.10", "10.04" and "10.10". However, all versions lead to the same driver: lexmark-08z-series-driver-1.0-1.i386.deb.sh.tar.gz (Last updated: 2012-04-13). While installing this driver, the installer asks me to connect the device. As soon as I connect it via USB, Ubuntu now adds the printer automatically. So after the installation completed, I had 2 printers set up. But I can't print anything (I tried it with both printer configurations). Scanning works fine, though. So I guess the driver installation and the device connection are successful. When I try to print something, the print job is listed in the printing queue, but nothing happens. After some time, I get an error message which starts a debug wizard, but in the end it reads something like "Sorry, couldn't find the reason". I had several different error messages (unfortunately, I didn't record them), one was approximately like "printer cannot communicate with computer". Another said that my color ink was low (which is true, but black is full). Another said there was an input/output error. I tried it with Ubuntu 11.10. Because I read that some people had success with 10.04., I installed it in QEMU and installed the driver there, too. Same problem, though. I'd like to upgrade to 12.04, if it should work there for any reason, but I read that for some people this printer stopped working in 12.04 :/ So, it would be best if the printer would work in 12.04. If that's not possible, I'd be fine with starting a QEMU virtual machine with any GNU/Linux distribution that works with my printer.

  • ODI 12c - Getting up and running fast

    - by David Allan
    Here's a quick A-B-C to show you how to quickly get up and running with ODI 12c, from getting the software to creating a repository via wizard or the command line, then installing an agent for running load plans and the like. A. Get the software from OTN and install studio. Check out this viewlet here for quickly doing this. B. Create a repository using the RCU, check out this viewlet here which uses the FMW Repository Creation Utility.  You can also silently create (and drop) a repository using the command line, this is really easy. .\rcu -silent -createRepository -connectString yourhost:1521:orcl.st-users.us.oracle.com -dbUser sys -dbRole sysdba -useSamePasswordForAllSchemaUsers true -schemaPrefix X -component ODI -component IAU  -component IAU_APPEND  -component IAU_VIEWER -component OPSS < passwords.txt where the passwords file contains info such as; sysdba_passwd newschema_passwd odi_user_passwd D workreposname workrepos_passwd  You can find details about the silent use of RCU here in the FMW documentation. C. Quickly create an agent for executing load plans and the like -  there is a great OBE for this, check it out here. If you are on your laptop and just wanting as minimal an agent as possible then this link is a must. With these three steps you are ready to get to the fun stuff! Check out more OBEs here - keep on the lookout for more!

  • Linux DD command partition -to- partition

    - by Ben Jackson
    I just used the DD command to copy the contents of one partition over to another partition on another drive, like this: dd if=/dev/sda2 of=/dev/sdb2 bs=4096 conv=noerror sda2 partition was 66GB and sdb2 was 250GB. I read that by doing this the extra space on the drive I am copying to will be wasted, is this true? I wasn't worried about loosing the extra space for the time being however, I just ran: sudo kill -USR1 (PID) to view the current status of DD and it has written over 66GB of data, will it continue to write data until it gets to 250GB? If so, is there a way to stop the process without corrupting it as waiting for it to write blank space seems like a waste of time.

  • HTG Explains: Just How Bad Are Android Tablet Apps?

    - by Chris Hoffman
    Apple loves to criticize the state of Android tablet apps when pushing its own iPad tablets. But just how bad is the Android tablet app situation? Should you avoid Android tablets like the Nexus 7 because of the apps? It’s clear that Apple’s iPad is way ahead when it comes to the sheer quantity of tablet-optimized apps. It’s also clear that some popular apps — particularly touch-optimized games — only show up on iPad. But that’s not the whole story. The Basics First, let’s get an idea of the basic stuff that will work well for you on Android. An excellent web browser. Chrome has struggled with performance on Android, but hits its stride on the Nexus 7 (2013). Great, tablet-optimized apps for all of Google’s services, from YouTube to Gmail and Google Maps. Everything you need for reading, from Amazon’s Kindle app for eBooks, Flipboard and Feedly for new articles from websites, and other services like the popular Pocket read-it-later service. Apps for most popular media services, from Netflix, Hulu, and YouTube for videos to Pandora, Spotify, and Rdio for music. A few things aren’t available — you won’t find Apple’s iTunes and Amazon still doesn’t offer an Amazon Instant Video app for Android, while they do for iPad and even their own Android-based Kindle Fire devices. Android has very good app coverage when it comes to consuming content, whether you’re reading websites and ebooks or watching videos and listening to music. You can play almost any Android smartphone game, too. For content consumption, Android is better than something like Windows 8, which lacks apps for Google services like YouTube and still doesn’t have apps for popular media services like Spotify and Rdio. How Android Scales Smartphone Apps Let’s look at how Android scales smartphone apps. Now, bear with us here — we know “scaling” is a dirty word considering how poorly Apple’s iPad scales iPhone apps, but it’s not as bad on Android. When an iPad runs an iPhone app, it simply doubles the pixels and effectively zooms in. For example, if you had  Twitter app with five tweets visible at once on an iPhone and ran the same app on an iPad, the iPad would simply “zoom in” and enlarge the same screen — you’d still see five tweets, but each tweet would appear larger. This is why developers create optimized iPad apps with their own interfaces. It’s especially important on Apple’s iOS. Android devices come in all shapes and sizes, so Android apps have a smarter, more intelligent way to adapt to different screen sizes. Let’s say you have a Twitter app designed for smartphones and it only shows five tweets at once when run on a phone. If you ran the same app on a tablet, you wouldn’t see the same five tweets — you’d see ten or more tweets. Rather than simply zooming in, the app can show more content at the same time on a tablet, even if it was never optimized for tablet-size screens. While apps designed for smartphones aren’t generally ideal, they adapt much better on Android than they do on an iPad. This is particularly true when it comes to games. You’re capable of playing almost any Android smartphone game on an Android tablet, and games generally adapt very well to the larger screen. This gives you access to a huge catalog of games. It’s a great option to have, especially when you look at Microsoft’s Window 8 and consider how much better the touch-based app and game selection would be if Microsoft allowed its users to run Windows Phone games on Windows 8. 7-inch vs 10-inch Tablets The Twitter example above wasn’t just an example. The official Twitter app for Android still doesn’t have a tablet-optimized interface, so this is the sort of situation you’d have to deal with on an Android tablet. On the popular Nexus 7, Twitter is an example of a smartphone app that actually works fairly well — in portrait mode, you can see many more tweets on screen at the same time and none of the space really feels all that wasted. This is important to consider — smartphone apps like Twitter often scale quite well to 7-inch screens because a 7-inch screen is much closer in form factor to a smartphone than a 10-inch screen is. When you begin to look at 10-inch Android tablets that are the same size as an iPad, the situation changes. While the Twitter app works well enough on a Nexus 7, it looks horrible on a Nexus 10 or other 10-inch tablet. Running many smartphone-designed apps — possible with the exception of games — on a 10-inch tablet is a frustrating, poor experience. There’s much more white, empty space in the interface. It feels like you’re using a smartphone app on a large screen, and what’s the point of that? A tablet-optimized Twitter app for Android is finally on its way, but this same situation will repeat with many other types of apps. For example, Facebook doesn’t offer a tablet-optimized interface, but it’s okay on a Nexus 7 anyway. On a 10-inch screen, it probably wouldn’t be anywhere near as nice an experience. It goes without saying that Facebook and Twitter both offer iPad apps with interfaces designed for a tablet-size screen. Here’s another problematic app — the official Yelp app for Android. Even just using it on a 7-inch Nexus 7 will be a poor experience, while it would be much worse on a larger 10-inch tablet app. Now, it’s true that many — maybe even most — of the popular apps you might want to run today are optimized for Android tablets. But, when you look at the situation when it comes to popular apps like Twitter, Facebook, and Yelp, it’s clear Android is still behind in a meaningful way. Price Let’s be honest. The thing that really makes Android tablets compelling — and the only reason Android tablets started seeing real traction after years of almost complete dominance by Apple’s iPads — is that Android tablets are available for so much cheaper than iPads. Google’s latest Nexus 7 (2013) is available for only $230. Apple’s non-retina iPad Mini is available at $300, which is already $70 more. In spite of that, the iPad Mini has much older, slower internals and a much lower resolution screen. It’s not as nice to look at when it comes to reading or watching movies, and the iPad Mini reportedly struggles to run Apple’s latest iOS 7. In contrast, the new Nexus 7 has a very high resolution screen, speedy internals, and runs Android very well with little-to-no lag in real use. We haven’t had any problems with it, unlike all the problems we unfortunately encountered with the first Nexus 7. For a really comparable experience to the current Nexus 7, you’d want to get one of Apple’s new retina iPad Minis. That would cost you $400, another $170 over the Nexus 7. In fact, it’s possible to regularly find sales on the Nexus 7, so if you waited you could get it for just $200 — half the price of the iPad mini with a comparable screen and internals. (In fairness, the iPad certainly has better hardware — but you won’t feel if it you’re just using your tablet to browse the web, watch videos, and do other typical tablet things.) This makes a tablet like the popular Nexus 7 a very good option for budget-conscious users who just want a high-quality device they can use to browse the web, watch videos, play games, and generally do light computing. There’s a reason we’re focusing on the Nexus 7 here. The combination of price and size brings it to a very good place. It’s awfully cheap for the high-quality experience you get, and the 7-inch screen means that even the non-tablet-optimized apps you may stumble across will often work fairly well. On the other hand, more expensive 10-inch Android tablets are still a tougher sell. For $400-$500, you’re getting awfully close to Apple’s full-size iPad price range and Android tablets don’t have as good an app ecosystem as an iPad. It’s hard to recommend an expensive, 10-inch Android tablet over a full-size iPad to average users. In summary, the Android app tablet app situation is nowhere near as bad as it was a few years ago. The success of the Nexus 7 proves that Android tablets can be compelling experiences, and there are a wide variety of strong apps. That said, more expensive 10-inch Android tablets that compete directly with the full-size iPad on price still don’t make much sense for most people.  Unless you have a specific reason for preferring an Android tablet, it’s tough not to recommend an iPad if you’re looking at spending $400+ on a 10-inch tablet.

  • Docking Station Disabling/Enabling Network Connection

    - by bryan_cook
    Whenever I dock my laptop onto my docking station, Windows disables my Wireless Network Connection and enables my Wired Network Connection. Whenever I undock my laptop, Windows disables my Wired Network Connection and enables my Wireless Network Connection. Is there a way to disable this feature? After Windows performs the automatic disabling/enabling, I run into errors when I try to disable the now-enabled connection, specifically "It is not possible to disable the connection at this time. This connection may be using one or more protocols that do not support Plug-and-Play, or it may have been initiated by another user or the system account." I'm assuming the latter portion of the error is true ... my network connections are being enabled/disabled under a system account. Regardless, I'd just like to disable the feature altogether. For reference, I'm working with Windows XP Professional on a Dell Latitude D630. Thanks in advance!

  • Implementing dry-run in bash scripts

    - by Andrei Serdeliuc
    How would one implement a dry-run option in a bash script? I can think of either wrapping every single command in an if and echoing out the command instead of running it if the script is running with dry-run. Another way would be to define a function and then passing each command call through that function. Something like: function _run () { if [[ "$DRY_RUN" ]]; then echo $@ else $@ fi } `_run mv /tmp/file /tmp/file2` `DRY_RUN=true _run mv /tmp/file /tmp/file2` Is this just wrong and there is a much better way of doing it?

  • extra configuration needed after installing SSL certificate?

    - by ptriek
    We recently developed two rather simple PHP applications for AXA (European bank). URL's are axa.tfo.be/incentives/cipres and axa.tfo.be/incentives/zrkk (access to both sites is restricted to visitors with cookies with encrypted passwords) On a previous security audit by an external company several security issues have been found. All these issues have been solved by a collleague PHP developer. However, one last requirement has been added - all data should be transfered over https. My php collegue is on holiday, however - and unavailable at the moment. So I contacted my host, and asked for installing SSL certificate. I myself have no knowledge/experience with SSL, so I'm a bit at loss for the following problems. Comodo SSL certificate + unique IP address has been installed today by my webhost for subdomain axa.tfo.be (by www.combell.be). However, it doesn't seem to be working. I posted a question about this earlier today, and was told not to worry, see link: http://serverfault.com/questions/339320/what-happens-if-you-install-an-ssl-certificate Current problems: the web applications aren't accessible over https, http works though (if a valid cookie is available) there's a static html page at http://axa.tfo.be/incentives/cipres/static.html, even that page is only accessible over http My webhost is telling me that 'my application probably doesn't support SSL', and has asked me to set an SSL variable to true in my php code. So my questions: I have basic knowledge of php, but don't know where to start regarding the 'php ssl variable'. The sites have been online for some time, and have been developed for regular php access. (Google didn't bring me any help, either.) Can anyone point me in the right direction, or give me some clues about whether/what I should ask my webhost for further assistance? (I'm a bit on a tight schedule, the sites will be audited again on monday, and it's a customer i wouldn't want to loose...) Thanks for looking into this, and sorry if my questions sound a bit nooby - I'm a webdesigner, not a server specialist...

  • Insufficient permissions within Eclipse when installed via synaptic in Ubuntu 12.04

    - by Clayton
    I installed Eclipse via the Synaptic Package Manager on Ubuntu 12.04 Desktop (more details on footer). However, from within Eclipse, I lack sufficient permissions to perform upgrades on my package and add-ons. I'm a recovering Windows user, and while I have a couple of years Ubuntu experience, I am unfamiliar with the command-line and mainly interact through the packaged GUI. Specifically, I am trying to install the upgrade for Eclipse CVS Clientorg.eclipse.cvs.feature.group1.3.100.v20110520-0800-7B78FHl9VF7BD7KBM4GP9C I am tracking the varying installation advice on a similar question eclipse install: Gaurav Butola Basically, the most current upgrades are available directly from eclipse?... But at some point I remember reading that the latest version of eclipse had been designed for the previous LTS of Ubuntu - I don't know if that is still true. I have read about the vulnerabilities of Java 6, and so I have gone with Open Java 7 openjdk-amd64 (if that has any relevance to which Eclipse package and installation method I choose). But I'm not crazy about the idea of creating a gksudo link in the sidebar launcher. I don't know enough about chown to use it - if that's even appropriate (I don't want stray java escaping from Eclipse and connecting to SkyNet). Another possible solution that I foresee is modifying my user's group memberships/privileges on the file system as a whole. The only other information that I think might be relevant is that I notice that Synaptic installed all of the files into /usr/ instead of /opt/ like I have seen recommended. So should I be changing ownership, reinstalling using a non-Synaptic method, or what? Any advice is greatly appreciated.

And we've heard from the likes of: "Uncle Bob" Martin - Who warned us about "the consequences of making a mess". Michael C. Feathers - Who gave us guidance for 'Working Effectively With Legacy Code'. So certainly the software engineering community is aware of these issues. But I feel like our aggregate society does not appreciate how these issues can plague working systems and applications. As Steve McConnell notes: ...Unlike financial debt, technical debt is much less visible, and so people have an easier time ignoring it. If this is true, and I believe that it is, then I fear that governments and businesses may defer regular maintenance and fortification against hackers until it is too late. [Much like NYC and the steam pipes.] My Question: Do you share my concern? And if so, is there a way that we can avoid the software equivalent of NYC and the steam pipes?

  • mod_deflate Supported Encodings for Compression

    - by sparc
    It seems to me, that mod_deflate in Apache 2.2 will always return: Content-Encoding: gzip and never: Content-Encoding: deflate It was explained to me, that although there may be a deflate algorithm, mod_deflate is named after a file-format, in which the algorithm could be any of: gzip, bzip. pkzip Of those three, mod_deflate provides gzip. It seems as though gzip is the most popular and widely-supported algorithm in web browsers, but I know some web servers and proxies do return Content-Encoding: deflate. Aside from the confusion of the module's name, it true that mod_deflate will only return Content-Encoding: gzip? Thank you.

  • What can cause SQL 2008 Transaction Log Shipping to stop functioning?

    - by Rick
    I read somewhere that doing a backup or when Maintenance Plan runs can cause Log Shipping to stop functioning. Is this true? What should we watch out for once our Transaction Log Shipping is in place that could stop it? A Log Shipping test we were doing between two databases on the same SQL 2008 server appeared to stop working without any error. When we checked the History of the LSRestore_* job it was always ignoring the new *.trn files. Any suggestions? Thanks.

  • How to ...set up new Java environment - largely interfaces...

    - by Chris Kimpton
    Hi, Looks like I need to setup a new Java environment for some interfaces we need to build. Say our system is X and we need to interfaces to systems A, B and C. Then we will be writing interfaces X-A, X-B, X-C. Our system has a bus within it, so the publishing on our side will be to the bus and the interface processes will be taking from the bus and mapping to the destination system. Its for a vendor based system - so most of the core code we can't touch. Currently thinking we will have several processes, one per interface we need to do. The question is how to structure things. Several of the APIs we need to work with are Java based. We could go EJB, but prefer to keep it simple, one process per interface, so that we can restart them individually. Similarly SOA seems overkill, although I am probably mixing my thoughts about implementations of it compared to the concepts behind it... Currently thinking that something Spring based is the way to go. In true, "leverage a new tech if possible"-style, I am thinking maybe we can shoe horn some jruby into this, perhaps to make the APIs more readable, perhaps event-machine-like and to make the interface code more business-friendly, perhaps even storing the mapping code in the DB, as ruby snippets that get mixed in... but thats an aside... So, any comments/thoughts on the Spring approach - anything more up-to-date/relevant these days. EDIT: Looking a JRuby further, I am tempted to write it fully in JRuby... in which case do we need any frameworks at all, perhaps some gems to make things clearer... Thanks in advance, Chris

  • XNA and C# vs the 360's in order processor

    - by Richard Fabian
    Having read this rant, I feel that they're probably right (seeing as the Xenon and the CELL BE are both highly sensitive to branchy and cache ignorant code), but I've heard that people are making games fine with C# too. So, is it true that it's impossible to do anything professional with XNA, or was the poster just missing what makes XNA the killer API for game development? By professional, I don't mean in the sense that you can make money from it, but more in the sense that the more professional games have phsyics models and animation systems that seem outside the reach of a language with such definite barriers to the intrinsics. If I wanted to write a collision system or fluid dynamics engine for my game, I don't feel like C# offers me the chance to do that as the runtime code generator and the lack of intrinsics gets in the way of performance. However, many people seem to be fine working within these constraints, making their successful games but seemingly avoiding any of the problems by omission. I've not noticed any XNA games do anything complex other than what's already provided by the libraries, or handled by shaders. Is this avoidance of the more complex game dynamics because of teh limitations of C#, or just people concentrating on getting it done? In all honesty, I can't believe that AI war can maintain that many units of AI without some data oriented approach, or some dirty C# hacks to make it run better than the standard approach, and I guess that's partly my question too, how have people hacked C# so it's able to do what games coders do naturally with C++?

  • Proper Data Structure for Commentable Comments

    - by Wesley
    Been struggling with this on an architectural level. I have an object which can be commented on, let's call it a Post. Every post has a unique ID. Now I want to comment on that Post, and I can use ID as a foreign key, and each PostComment has an ItemID field which correlates to the Post. Since each Post has a unique ID, it is very easy to assign "Top Level" comments. When I comment on a comment however, I feel like I now need a PostCommentComment, which attaches to the ID of the PostComment. Since ID's are assigned sequentially, I can no longer simply use ItemID to differentiate where in the tree the comment is assigned. I.E. both a Post and a Post Comment might have an ID of '5', so my foreign key relationship is invalid. This seems like it could go on infinitely, with PostCommentCommentComment's etc... What's the best way to solve this? Should I have a field in the comment called "IsPostComment" or something of the like to know which collection to attach the ID to? This strikes me as the best solution I've seen so far, but now I feel like I need to make recursive DataBase calls which start to get expensive. Meaning, I get a Post and get all PostComments where ItemID == Post.ID && where IsPostComment == true Then I take that as a collection, gather all the ID's of the PostComments, and do another search where ItemID == PostComment[all].ID && where IsPostComment == false, then repeat infinitely. This means I make a call for every layer, and if I'm calling 100 Posts, I might make 1000 DB calls to get 10 layers of comments each. What is the right way to do this?

  • Firewall blocks FTP PASV response

    - by harper
    0 down vote favorite I have an FTP server that supports passive server mode (using PASV command). This works fine with Windows XP. When I want to access this server from Windows Vista or Windows 7 with firewall enabled I experience a immediate connection shutdown. A reset packet is sent to the server, the socket is signaled that the server had reset the connection (what is not true). The problem disappears when the firewall is disabled. Connections to other FTP servers work correctly. The difference is that the servers response to PASV does not enclose the address field with parentheses. This is legal as documented in RFC-959 and RFC-1132. How can I configure the firewall to stop this bad behavior?

  • Rotation of bitmap using a frame by frame animation

    - by pengume
    Hey every one I know this has probably been asked a ton of times but I just wanted to clarify if I am approaching this correctly, since I ran into some problems rotating a bitmap. So basically I have one large bitmap that has four frames drawn on it and I only draw one at a time by looping through the bitmap by increments to animate walking. I can get the bitmap to rotate correctly when it is not moving but once the animation starts it starts to cut off alot of the image and sometimes becomes very fuzzy. I have tried public void draw(Canvas canvas,int pointerX, int pointerY) { Matrix m; if (setRotation){ // canvas.save(); m = new Matrix(); m.reset(); // spriteWidth and spriteHeight are for just the current frame showed m.setTranslate(spriteWidth / 2, spriteHeight / 2); //get and set rotation for ninja based off of joystick m.preRotate((float) GameControls.getRotation()); //create the rotated bitmap flipedSprite = Bitmap.createBitmap(bitmap , 0, 0,bitmap.getWidth(),bitmap.getHeight() , m, true); //set new bitmap to rotated ninja setBitmap(flipedSprite); // canvas.restore(); Log.d("Ninja View", "angle of rotation= " +(float) GameControls.getRotation()); setRotation = false; } And then the Draw Method here // create the destination rectangle for the ninjas current animation frame // pointerX and pointerY are from the joystick moving the ninja around destRect = new Rect(pointerX, pointerY, pointerX + spriteWidth, pointerY + spriteHeight); canvas.drawBitmap(bitmap, getSourceRect(), destRect, null); The animation is four frames long and gets incremented by 66 (the size of one of the frames on the bitmap) for every frame and then back to 0 at the end of the loop.
