  • No Orca magnification in Ubuntu 12.04

    - by Mr Dimly
    I'm a visually impaired Linux/Ubuntu newbie. I've installed 12.04 from a live CD and have the Orca screen reader running at start up. Speach works fine but there is no magnification. When I open Orca preferences there is no magnification tab. I have tried uninstalling Orca and re-installing if from the Software Centre, but still no magnification. Can anyone tell me how to add magnification to Orca? Thanks.

  • rotate sprite and shooting bullets from the end of a cannon

    - by Alberto
    Hi all i have a problem in my Andengine code, I need , when I touch the screen, shoot a bullet from the cannon (in the same direction of the cannon) The cannon rotates perfectly but when I touch the screen the bullet is not created at the end of the turret This is my code: private void shootProjectile(final float pX, final float pY){ int offX = (int) (pX-canon.getSceneCenterCoordinates()[0]); int offY = (int) (pY-canon.getSceneCenterCoordinates()[1]); if (offX <= 0) return ; if(offY>=0) return; double X=canon.getX()+canon.getWidth()*0,5; double Y=canon.getY()+canon.getHeight()*0,5 ; final Sprite projectile; projectile = new Sprite( (float) X, (float) Y, mProjectileTextureRegion,this.getVertexBufferObjectManager() ); mMainScene.attachChild(projectile); int realX = (int) (mCamera.getWidth()+ projectile.getWidth()/2.0f); float ratio = (float) offY / (float) offX; int realY = (int) ((realX*ratio) + projectile.getY()); int offRealX = (int) (realX- projectile.getX()); int offRealY = (int) (realY- projectile.getY()); float length = (float) Math.sqrt((offRealX*offRealX)+(offRealY*offRealY)); float velocity = (float) 480.0f/1.0f; float realMoveDuration = length/velocity; MoveModifier modifier = new MoveModifier(realMoveDuration,projectile.getX(), realX, projectile.getY(), realY); projectile.registerEntityModifier(modifier); } @Override public boolean onSceneTouchEvent(Scene pScene, TouchEvent pSceneTouchEvent) { if (pSceneTouchEvent.getAction() == TouchEvent.ACTION_MOVE){ double dx = pSceneTouchEvent.getX() - canon.getSceneCenterCoordinates()[0]; double dy = pSceneTouchEvent.getY() - canon.getSceneCenterCoordinates()[1]; double Radius = Math.atan2(dy,dx); double Angle = Radius * 180 / Math.PI; canon.setRotation((float)Angle); return true; } else if (pSceneTouchEvent.getAction() == TouchEvent.ACTION_DOWN){ final float touchX = pSceneTouchEvent.getX(); final float touchY = pSceneTouchEvent.getY(); double dx = pSceneTouchEvent.getX() - canon.getSceneCenterCoordinates()[0]; double dy = pSceneTouchEvent.getY() - canon.getSceneCenterCoordinates()[1]; double Radius = Math.atan2(dy,dx); double Angle = Radius * 180 / Math.PI; canon.setRotation((float)Angle); shootProjectile(touchX, touchY); } return false; } Anyone know how to calculate the coordinates (X,Y) of the end of the barrel to draw the bullet?

  • Use CSS Selectors with HtmlUnit

    - by kerry
    HtmlUnit is a great library for performing web integration tests in Java.  But sometimes node traversal can be somewhat cumbersome. Fear not fellow automated tester (good for you!).  I found a great little project on Github that will allow you to query your document for elements via css selectors similar to jQuery. The project is located at https://github.com/chrsan/css-selectors.  You can use Maven to build it, or download 1.0.2 here.  Beware.  I will not be updating this link so I suggest you download the latest code. In any case, you can use it like so: // from HtmlUnit getting started final WebClient webClient = new WebClient(); final HtmlPage page = webClient.getPage("http://htmlunit.sourceforge.net"); final DOMNodeSelector cssSelector = new DOMNodeSelector(page.getDocumentElement()); final Set elements = cssSelector.querySelectorAll("div.section h2"); final Node first = elements.iterator().next(); assertThat(first.getTextContent(), equalTo("HtmlUnit")); The only problem here is that the querySelectAll returns a Set<Node>.  Not HtmlElement like we may want in some cases.   However, if you were to reflect on the Set, you would find that it is indeed a Set of HtmlElement objects. Typically, I like to create a base class for my web tests.  Just for fun, I am using the $ method similar to jQuery. public class WebTestBase { protected WebClient webClient; protected HtmlPage htmlPage; protected void goTo(final String url){ return (HtmlPage)webClient.getPage(url); } protected List $(final String cssSelector) { final DOMNodeSelector cssSelector = new DOMNodeSelector(htmlPage.getDocumentElement()); final Set nodes = cssSelector.querySelectorAll("div.section h2"); // for some reason Set cannot be cast to Set? final List elements = new ArrayList(nodes.size()); for (final Node node : nodes) { elements.add((HtmlElement)node); } return elements; } } Now we can write tests like this: public class LoginWebTest extends WebTestBase { @Test public void login_page_has_instructions() throws Exception { goTo(baseUrl + "/login") assertThat( $("p.instructions").size(), equalTo(1) ); } }

  • How do I stop icons appearing on the desktop in a particular area?

    - by Seamus
    When I download something to my desktop, or insert a CD or flash drive, the icon appears on my desktop.

  • Checking media [Fail] on boot

    - by karolsojko
    Lately I've been getting this black screen at boot time with 2 lines saying Checking media [Fail] And the time of booting has extended greatly due to that thing (like from seconds to a minute) I have a Dell XPS15 with SSD and I'm running Ubuntu 12.10 and it was not like this before. I don't have a clue what is it connected with - maybe it's due to a kernel update or something. And what do those 2 lines mean.

  • SceneManagers as systems in entity system or as a core class used by a system?

    - by Hatoru Hansou
    It seems entity systems are really popular here. Links posted by other users convinced me of the power of such system and I decided to try it. (Well, that and my original code getting messy) In my project, I originally had a SceneManager class that maintained needed logic and structures to organize the scene (QuadTree, 2D game). Before rendering I call selectRect() and pass the x,y of the camera and the width and height of the screen and then obtain a minimized list containing only visible entities ordered from back to front. Now with Systems, originally in my first attempt my Render system required to get added all entities it should handle. This may sound like the correct approach but I realized this was not efficient. Trying to optimize It I reused the SceneManager class internally in the Renderer system, but then I realized I needed methods such as selectRect() in others systems too (AI principally) and make the SceneManager accessible globally again. Currently I converted SceneManager to a system, and ended up with the following interface (only relevant methods): /// Base system interface class System { public: virtual void tick (double delta_time) = 0; // (methods to add and remove entities) }; typedef std::vector<Entity*> EntitiesVector; /// Specialized system interface to allow query the scene class SceneManager: public System { public: virtual EntitiesVector& cull () = 0; /// Sets the entity to be used as the camera and replaces previous ones. virtual void setCamera (Entity* entity) = 0; }; class SceneRenderer // Not a system { vitual void render (EntitiesVector& entities) = 0; }; Also I could not guess how to convert renderers to systems. My game separates logic updates from screen updates, my main class have a tick() method and a render() method that may not be called the same times. In my first attempt renderers were systems but they was saved in a separated manager, updated only in render() and not in tick() like all other systems. I realized that was silly and simply created a SceneRenderer interface and give up about converting them to systems, but that may be for another question. Then... something does not feel right, isn't it? If I understood correctly a system should not depend on another or even count with another system exposing an specific interface. Each system should care only about its entities, or nodes (as optimization, so they have direct references to relevant components without having to constantly call the component() or getComponent() method of the entity).

  • asus n550jv audio problem: no sound from notebook' speakers

    - by skywalker
    Ubuntu 13.10. The problem is: the internal speakers don't work. I have no problem when I'm using the headphones.

  • `make install` fails apparently due to typo, but not in makefile: How to find and fix?

    - by Archelon
    I'm trying to install the fujitsu-usb-touchscreen drivers from here, on Kubuntu 12.04 on my new Fujitsu LifeBook P1630. (See fujitsu-usb-touchscreen on kubuntu 13.04 (64-bit) on P1630: `make` errors.) I downloaded the .zip file, unzipped it, and ran make in the directory thus created; this all worked as expected. However, when I run sudo checkinstall (which invokes make install), things go less well. On the first attempt the installation aborted with the following error: make: execvp: /etc/init.d/fujitsu_touchscreen: Permission denied make: *** [install] Error 127 I eventually resolved this by $ sudo chmod +x /etc/init.d/fujitsu_touchscreen But although a second sudo checkinstall then does not give the execvp error, it still fails at a later stage, and the log (on stdout) shows this dpkg error: dpkg: error processing /home/archelon/fujitsu-touchscreen-driver/cybergene-fujitsu-usb-touchscreen-112fdb75b406/cybergene-fujitsu-usb-touchscreen-112fdb75b406_amd64.deb (--install): unable to create `/sys/module/fujitsu/usb/touchscreen/parameters/touch_maxy.dpkg-new' (while processing `/sys/module/fujitsu/usb/touchscreen/parameters/touch_maxy'): No such file or directory And, indeed, there is no /sys/module/fujitsu/usb/touchscreen/parameters/touch_maxy; there is, however, /sys/module/fujitsu_usb_touchscreen/parameters/touch_maxy, and this is presumably what was intended. But this incorrect filename does not appear in the makefile or any other file in the directory, at least not that I can find. Nor does it appear, as I discovered after running sudo checkinstall --install=no as suggested below, in the .deb package created by checkinstall. Where might such a typographical error be originating, and how would I go about fixing it? Edited to add: I'm viewing the contents of the .deb file with ark, Kubuntu's default tool. It contains only three files: control.tar.gz, data.tar.gz, and debian-binary. data.tar.gz contains the directory tree that appears to match up to the usual root filesystem, with /etc, /lib, /sys, and /usr directories. (Looking at other .deb files on my system, this structure appears to be typical.) Here's a screenshot: . (Full size.) Here's another screenshot showing that control.tar.gz contains three files, one of which is empty: . (Full size.) Here's the actual .deb file: https://www.dropbox.com/s/odwxxez0fhyvg7a/cybergene-fujitsu-usb-touchscreen_112fdb75b406-1_amd64.deb Edited 2013-09-28 to add: After reinstalling Kubuntu 12.04 again, this time recreating the /home partition (which, again, had been generated during an install of 13.04), I can no longer reproduce this error. I am still curious to know how the underscores got changed to slashes, but it looks as though nobody has any idea. It is perhaps also of interest to note that while I have still not successfully run checkinstall against this package, I have done make install; it requires the executabilization of /etc/init.d/fujitsu_touchscreen and the installation of hal, and the GUI freezes shortly after installation completes, and there is no particular new functionality afterwards that I have noticed, and the system can no longer resume from being suspended; however, this will be pursued elsewhere.

Each time I disconnect my Dell Studio 15 from my Dell 36" monitor, I have to reconnect through the System/Monitor protocol. Question: Is there a way to set it up so once I slide my laptop under the stand, reconnect monitor cable, 3 usb's and press start that the Monitor screen will go 'live' without having to start all over?

  • Failed 12.04 installation

    - by Rob Sayer
    I tried installing Ubuntu 12.04 today. Not an upgrade, a new installation. It didn't work. My computer specs: Computer: Compaq presario CQ-104CA OS: Windows 7 Home 64 bit CPU: AMD V140 BIOS: latest Graphics: amd m880g with ati mobility radeon hd 4250 Wireless: atheros ar9285 Internal HD:SATA I wasn't connected to the internet at the time ... I know of a number of people who have installed ubuntu unconnected and just updated later. It seemed to go normally until I got to the part where I chose to install dual boot linux/windows. Then, the screen went black and the following test appeared (I left out the [OK]'s): checking battery state starting crash report submission daemon stating cpu interrupts balancing daemon stopping system V runlevel compatibility starting configure network device security stopping configure network device security stopping cold plug devices stopping log initial device creation starting enable remaining boot-time encrypting devices starting configure network device security starting save udev log and update rules stopping save udev log and update rules stopping enable remaining boot-time encrypted block devices checking for running unattended-upgrades acpid: exiting speech-dispatcher disabled: edit /etc/default/speech-disorder At this point, the CD is ejected. Then nothing. If I press the return key, it boots Windows. I don't think that's what's supposed to happen. Thinking the cd media or dvd drive may have been faulty, I downloaded the .iso again and made a bootable USB stick, as per your instructions. This time there was no cryptic crash screen. It just booted windows. I can't find any log files it may have left. Thinking the amd64 version may have been the wrong one, I tried downloading the x86 version. Same thing, both from cd and usb drive. Note I downloaded both files twice. I doubt it was a corrupted d/l. This is supposed to be a simple, transparent install. I went to the time and trouble of looking up my devices and drivers re ubuntu beforehand, and was prepared to do some configuration, though I know someone who has the same wireless device and his worked righted out of the box. But I spent over 3 hours trying to install it with only the above to show for it.

First of all, the readme says to use the make command, and I already got errors: $ make make[1]: Entering directory `/usr/src/linux-headers-2.6.35-22-generic' CC [M] /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.o /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c: In function ‘rtl8192_usb_probe’: /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12325: error: ‘struct net_device’ has no member named ‘open’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12326: error: ‘struct net_device’ has no member named ‘stop’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12327: error: ‘struct net_device’ has no member named ‘tx_timeout’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12328: error: ‘struct net_device’ has no member named ‘do_ioctl’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12329: error: ‘struct net_device’ has no member named ‘set_multicast_list’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12330: error: ‘struct net_device’ has no member named ‘set_mac_address’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12331: error: ‘struct net_device’ has no member named ‘get_stats’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12332: error: ‘struct net_device’ has no member named ‘hard_start_xmit’ make[2]: *** [/home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.o] Error 1 make[1]: *** [_module_/home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-2.6.35-22-generic' make: *** [all] Error 2 /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/ is the path where I copied the drivers on my computer.

Alternate Payments We've seen several alternate payment schemes emerge over the last two years, and 2011 may be the year one of them takes hold. Any competition that can drive down fees will be good for everyone. I'm betting that Apple will add NFC chips to their next version of the iPhone, then enable payments in stores using iTunes accounts on the backend. Paypal will continue to make inroads, and Isis will announce a pilot. The iPhone 4S did not contain an NFC chip, so we’ll have to continuing waiting for the iPhone 5. PayPal announced its moving into in-store payments, and Google launched its wallet in selected cities.  Overall I think the payment scene is heating up and that trend will continue. 2. Engineered Systems The industry is moving toward purpose-built appliances that are optimized across the entire stack. Oracle calls these "engineered systems" and the first two examples are Exadata and Exalogic, but there are other examples from other vendors. These are particularly important to the retail industry because of the volume of data that must be processed. There should be continued adoption in 2011. Oracle reports that Exadata is its fasting growing product, and at the recent OpenWorld it announced the SuperCluster and Exalytics products, both continuing the engineered systems trend. SAP’s HANA continues to receive attention, and IBM also seems to be moving in this direction. 3. Social Analytics There are lots of tools that provide insight into how a brand is perceived across popular internet sites, but as far as I know, these tools are not industry specific. The next step needs to mine the data and determine how it should influence retail operations. The data needs to help retailers determine how they create promotions, which products to stock, and how to keep consumers engaged. Social data alone does not provide the answers, but its one more data point that will help retailers make better decisions. Look for some vendor consolidation to help make this happen. In March, Salesforce.com acquired leading social monitoring vendor Radian6 and followed up with acquisitions of Heroku and Model Metrics. The notion of Social CRM seems to be going more mainstream now. 4. 2-D Barcodes Look for more QRCodes on shelf-tags, in newspaper circulars, and on billboards. It's a great portal from the physical world into the digital one that buys us time until augmented reality matures further. Nobody wants to type "www", backslash, and ".com" on their phones. QRCodes are everywhere. ‘Nuff said. 5. In the words of Microsoft, "To the Cloud!" My favorite "cloud application" is Evernote. If you take notes on your work laptop, you will inevitably need those notes on your home PC. And if you manage to solve that problem, you'll need to access them from your mobile phone. Evernote stores your notes in the cloud and provides easy ways to access them. Being able to access a service from anywhere and not having to worry about backups, upgrades, etc. is great. Retailers will start to rely on cloud services, both public and private, in the coming year. There were no shortage of announcements in this area: Amazon’s cloud-based Kindle Fire, Apple’s iCloud, Oracle’s Public Cloud, etc. I saw an interesting presentation showing how BevMo moved their systems to the cloud.  Seems like retailers are starting to consider the cloud for specific uses. 6. F-CommerceTop of Form Move over "E" and "M" so we can introduce "F-Commerce," which should go mainstream in 2011. Already several retailers have created small stores on Facebook, and it won't be long before Facebook becomes a full-fledged channel in the omni-channel world of retail. The battle between Facebook and Google will heat up over retail, where both stand to make lots of money. JCPenney and ASOS both put their entire catalogs on Facebook, and lots of other retailers have connected Facebook to their e-commerce site. I still think selling from the newsfeed is the best approach, and several retailers are trying that approach as well. I just don’t see Google+ as a threat to Facebook, so I think that battle is over.  I called 2011 The Year of F-Commerce, and that was probably accurate. Its good to look back at predictions, but we also have to think about what was missed.  I didn't see Amazon entering the tablet business with such a splash, although in hindsight it was obvious. Nor did I think HP would fall so far so fast.  Look for my 2012 predictions coming soon.
