• Ubuntu server 11.04 recognize only 1 core instead of 4

  - by Kreker

  I searched for other questions and googled a lot but I don't find a solution for solving this problem. Ubuntu Server 11.04 64bit installed on Dell Poweredge with Intel Xeon X5450. He only recognize 1 of the 4 cores I have. Tried to modify the GRUB config but didn't work. IN the machine BIOS I didn't find anything useful.

• KDE's Dolphin Can't See Connected devices such as Nikon, Canon Cameras

  - by Swapnil

  I have noticed this problem across all distros including Kubuntu and openSUSE. Many times my Nikon D 7000 and Canon HF 11 are not seen or mounted by Dolphin. When I connect the Cameras I don't get any notification in the tray which otherwise shows connected device. Ironically when I open Nautilus then I can clearly see the cameras mounted. I also have a request that what these devices don't appear on Dolphin's side panel automatically. It makes life easier for a users. https://bugs.launchpad.net/ubuntu/+source/dolphin/+bug/956806/+attachment/2879913/+files/dolphin.png

• Pandaboard crash on startup or freeze after minutes

  - by Meach

  I just received my Pandaboard ES (rev B) and I am having trouble after installing ubuntu-omap4-addons. Once I copied the image ubuntu-12.04-preinstalled-desktop-armhf+omap4.img on my sd card and boot the pandaboard with it, I run the following commands: sudo add-apt-repository ppa:tiomap-dev/release sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install ubuntu-omap4-extras At the end of the installation of ubuntu-omap4-extras, Ubuntu tells me that a problem occurs when the console displays: ldconfig deferred processing now taking place Clicking on "report the problem" tell me that the problem concerns pvr-omap4-dkms. I read somewhere that this can happen and it is better to reinstall pvr-omap4-dkms. Which I am doing by running: sudo apt-get install --reinstall pvr-omap4-dkms I reboot. Then the board has sometimes difficulties to start Ubuntu: it freezes during the loading page, only action I can do is unplugging the board to start it again. Some other times, Ubuntu load successfully but then freeze at another random time, in the range 20 - 40 minutes. I searched on internet for similar bug and found this: https://bugs.launchpad.net/ubuntu/+source/linux-ti-omap4/+bug/971091 So I typed this in: update-rc.d ondemand disable apt-get -y install cpufrequtils echo 'ENABLE="true" GOVERNOR="performance" MAX_SPEED="0" MIN_SPEED="0"' > /etc/default/cpufrequtils cpufreq-set -r -g performance reboot But it doesn't seems to fix the bug. Another detail: on startup, before the loading screen of Ubuntu (when there is the two penguins displayed :)), it shows this: [0.297271] CPU1: Unknown IPI message 0x1 [0.308990] omap_hwmod: mcpdm: _wait_target_ready error: -16 [0.354705] omap_mux_get_by_name: Could not find signal uart1_cts.uart1_cts [0.354766] omap_hwmod_mux_init: Could not allocate device mux entry [2.107086] thermal_get_slope:Getting slope is not supported for domain gpu [2.107116] thermal_get_offset:Getting offset is not supported for domain gpu [2.107299] stm_fw: vendor driver stm_ti1.0 registered [8.725555] OMAPRPC: Registration of OMAPRPC rpmsg service returned 0! debug=0 Any idea what can be wrong? I am not that good with Ubuntu so any help will be appreciated. Cheers! Meach

• Skype does not save configuration

  - by varsketiz

  Hello, on ubuntu 10.10, I have recently started to experience this problem: for some reason skype wont save any settings except "sign in on startup" when skype starts and tries to sign in it is unsuccessful (it shows incorrect password, in red) every time. no matter if I have provided good password the last time. I always have to click to show contacts in groups, it does not remember it. Every time I have to go to options and update some notification settings. I know all these things should be "remembered" by skype - this problem started only recently. I don't recall fiddling with any permissions that could have likely caused that. Do you know what the problem might be? I tried uninstall (marking complete configuration removal) and install fresh, but it still remembers my username (why??) Can I find skype configuration files on the filesystem somewhere and change permissions for them - or even better - edit the files to set what I want..?

• Posting to facebook from unity3d on iOS and android

  - by Guye Incognito

  I've made a game in unity3d for iOS and android. We have our own server to manage high scores and stuff like that. We'd also like to have the possibility post high scores to facebook, and also do things like this.. If you and your friend are have both posted a score for our game to facebook and you post a better score then you can send them a notification. I'm reading around about this now, but I'm wondering whats the normal way people do this? Possible ways.. Use the unity facebook SDK Looks like it would work but there are different versions for iOS and android. Call the facebook graph API directly from our server. This would unify the iOS and android versions and also it makes sense as our server holds / deals with all the highscore info. I can just imagine difficulties with logging in / authentication

• How do I compare two Excel documents?

  - by arathorn

  The compare function in Word 2007 is very handy -- is there a similar capability in Excel 2007? I can't seem to find it... The documents I'm trying to compare are essentially two versions of the same content. Unfortunately, "Track Changes" has not been used. If file comparison not a built-in feature, what alternatives are out there for doing this? UPDATE [2009-08-05]: I ran across this (somewhat dated) overview of some of the third-party options that are available: http://www.comparesuite.com/solutions/compare_utilities_review/compare-files-excel.htm UPDATE [2009-08-12]: I ended up going with the Beyond Compare answer, but several of the other answers below were adequate as well, and might be more useful for someone else. (E.g., if you don't own a license for BeyondCompare, or want a comparison GUI that's integrated into Excel.) See also: How do I diff two spreadsheets on Stack Overflow

• Orange Brightbox and NO-IP.com

  - by JSweete

  Strange one here i didnt know where to ask, and i know this is a developer resource but i was hoping with everyones tech know how someone may have a solution for my problem. Ok i had an orange livebox before and in the dynamic dns settings it had no-ip.com as a drop down option with login variables to update my account with a dynamic ip address. This worked great for years. However my livebox died and i now have a orange brightbox, and this doesnt have no-ip.com as a login update option for dynamic dns on my router. Does any one have any idea how i can get my domain to point to my home server with a dynamic ip address ideally for free? This is merely for testing and to have a backup server for my main remote server.

• Windows 7 sata disk not recognized after wake up from sleep state [closed]

  - by Gabber

  My windows 7 x64 PC/server worked fine until I installed a brand new seagate SATA hard disk (2 TB). My first disk was a IDE Maxtor (250 GB). I tried to use it as a secondary drive leaving the maxtor as primary and, when I put the computer in sleep state, on wake-up the SATA disk is not recognized anymore until next reboot. Now I'm trying to set it as primary disk (I copied the old HD contents with HD clone), when the computer goes in sleep state, on wake up it doesn't see the disc thus causing my system to crash. I tried the following: BIOS update (Asus M2V motherboard) but the situation worsened as the system didn't wake up from the sleep (with both my HD's) Reinstalling the drivers Bios changes Microsoft Hotfix KB977178 that seemed to address exactly my problem but gave me "The update is not applicable to your computer" message. Disabling hybrid sleep but no results.

• Marketing for Scheduled Online Events

  - by JT703

  Last year I started working with a team on our first major web project (We, the Pixels). I believe the idea is very solid, but it has a hard requirement for a group of people being on the site for the randomly scheduled events. We are having problems getting people to come and stay for these events. What is the proper marketing approach needed to bring people to the site for these events? We have recently done the following in an attempt to fix the problem: Added email notification of new events being created Added privileges based on rank Added text throughout the site encouraging setting up the events in the future so other users can have time see that it exists. Gotten involved in with other communities that would find the site interesting in order to promote (market) the site Advertised using Google Adwords Is there an standard marketing approach for such a case as this?

• Ubuntu crashes with menu bar launcher freeze during software centre use

  - by UbunUser

  I recently reinstalled Ubuntu 12.04 LTS on a Dell Studio 1588 64-bit and ran into crashes as I was installing some software on the software centre. Before this, I had display/screen problems that I needed to fix so I will briefly describe that in case it has any connection to the crashes. The problem was of screen crash/flickering (related to ATI Mobility Radeon HD 5400x) when trying to adjust brightness and so I followed guidance from an earlier chain (question 131967) to (a) use jockey to install fglrx update driver (deactivate experimental beta driver) and (b) edit grub to add acpi_backlight=vendor dell_laptop.backlight=0 The crashes that happened (twice, while software centre was just finishing installation in the background) was that all tabs (on open Firefox window) stayed open along with cursor control with mousepad but all menu bars disappeared completely along with the launcher and the keyboard also turned unresponsive. So there seemed to be no way to close windows or shut down the computer except for a forced hard shut down of the system using the start button. This is very similar to Questions #167540 and #298843, which seem to be closed. Why is this happening? Is there some update or fix I need to make? Thanks!

• Confusion with floats converted into ints during collision detection

  - by TheBroodian

  So in designing a 2D platformer, I decided that I should be using a Vector2 to track the world location of my world objects to retain some sub-pixel precision for slow-moving objects and other such subtle nuances, yet representing their bodies with Rectangles, because as far as collision detection and resolution is concerned, I don't need sub-pixel precision. I thought that the following line of thought would work smoothly... Vector2 wrldLocation; Point WorldLocation; Rectangle collisionRectangle; public void Update(GameTime gameTime) { Vector2 moveAmount = velocity * (float)gameTime.ElapsedGameTime.TotalSeconds wrldLocation += moveAmount; WorldLocation = new Point((int)wrldLocation.X, (int)wrldLocation.Y); collisionRectangle = new Rectangle(WorldLocation.X, WorldLocation.Y, genericWidth, genericHeight); } and I guess in theory it sort of works, until I try to use it in conjunction with my collision detection, which works by using Rectangle.Offset() to project where collisionRectangle would supposedly end up after applying moveAmount to it, and if a collision is found, finding the intersection and subtracting the difference between the two intersecting sides to the given moveAmount, which would theoretically give a corrected moveAmount to apply to the object's world location that would prevent it from passing through walls and such. The issue here is that Rectangle.Offset() only accepts ints, and so I'm not really receiving an accurate adjustment to moveAmount for a Vector2. If I leave out wrldLocation from my previous example, and just use WorldLocation to keep track of my object's location, everything works smoothly, but then obviously if my object is being given velocities less than 1 pixel per update, then the velocity value may as well be 0, which I feel further down the line I may regret. Does anybody have any suggestions about how I might go about resolving this?

• Unable to install Skype ("Unmet dependencies" error)

• Is acousting fingerprinting too broad for one audio file only?

  - by IBG

  So we were looking for some topics related to audio analysis and found acoustic fingerprinting. As it is, it seems like the most famous application for it is for identification of music. Enter our manager, who requested us to research and possible find an algorithm or existing code that we can use for this very simple approach (like it's easy, source codes don't show up like mushrooms): Always-on app for listening Compare the audio patterns to a single audio file (assume sound is a simple beep) If beep is detected, send notification to server With a flow this simple, do you think acousting fingerprinting is a broad approach to use? Should we stop and take another approach? Where to best start? We haven't started anything yet (on the development side) on this regard, so I want to get other opinion if this is pursuit is worth it or moot.

• State changes in entities or components

  - by GriffinHeart

  I'm having some trouble figuring how to deal with state management in my entities. I don't have trouble with Game state management, like pause and menus, since these are not handled as an entity component system; just with state in entities/components. Drawing from Orcs Must Die as an example, I have my MainCharacter and Trap entities which only have their components like PositionComponent, RenderComponent, PhysicsComponent. On each update the Entity will call update on its components. I also have a generic EventManager with listeners for different event types. Now I need to be able to place the traps: first select the trap and trap position then place the trap. When placing a trap it should appear in front of the MainCharacter, rendered in a different way and following it around. When placed it should just respond to collisions and be rendered in the normal way. How is this usually handled in component based systems? (This example is specific but can help figure out the general way to deal with entities states.)

  I use gVim 7.3.46 on Win 7.

• VMware Kernel Module Updater hangs on Ubuntu 13.04

  VMware Player has a nice auto-detection of kernel changes, and requests the user to compile the required modules in order to load them. This happens from time to time after a regular update of your system. Usually, the dialog of VMware Kernel Module Updater pops up, asks for root access authentication, and completes the compilation. VMware Player or Workstation checks if modules for the active kernel are available. In theory this is supposed to work flawlessly but in reality there are pitfalls occassionally. With the recent upgrade to Ubuntu 13.04 Raring Ringtail and the latest kernel 3.8.0-21 the actual VMware Kernel Module Updater simply disappeared and the application wouldn't start as expected. When you launch VMware Player as super user (root) the dialog would stall like so: VMware Kernel Module Updater stalls while stopping the services Prior to version 5.x of VMware Player or version 7.x of VMware Workstation you would run a command like: $ sudo vmware-config.pl to resolve the module version conflict but this doesn't work anyway. Solution Instead, you have to execute the following line in a terminal or console window: $ sudo vmware-modconfig --console --install-all Those switches are (as of writing this article) not documented in the output of the --help switch. But VMware already documented this procedure in their knowledge base: VMware Workstation stops functioning after updating the kernel on a Linux host (1002411). Update As of today I had the first kernel upgrade to version 3.8.0-22 in Ubuntu 13.04. Don't even try it without vmware-modconfig...

• Platform game collisions with Block

  - by Sri Harsha Chilakapati

  I am trying to create a platform game and doing wrong collision detection with the blocks. Here's my code // Variables GTimer jump = new GTimer(1000); boolean onground = true; // The update method public void update(long elapsedTime){ MapView.follow(this); // Add the gravity if (!onground && !jump.active){ setVelocityY(4); } // Jumping if (isPressed(VK_SPACE) && onground){ jump.start(); setVelocityY(-4); onground = false; } if (jump.action(elapsedTime)){ // jump expired jump.stop(); } // Horizontal movement setVelocityX(0); if (isPressed(VK_LEFT)){ setVelocityX(-4); } if (isPressed(VK_RIGHT)){ setVelocityX(4); } } // The collision method public void collision(GObject other){ if (other instanceof Block){ // Determine the horizontal distance between centers float h_dist = Math.abs((other.getX() + other.getWidth()/2) - (getX() + getWidth()/2)); // Now the vertical distance float v_dist = Math.abs((other.getY() + other.getHeight()/2) - (getY() + getHeight()/2)); // If h_dist > v_dist horizontal collision else vertical collision if (h_dist > v_dist){ // Are we moving right? if (getX()<other.getX()){ setX(other.getX()-getWidth()); } // Are we moving left? else if (getX()>other.getX()){ setX(other.getX()+other.getWidth()); } } else { // Are we moving up? if (jump.active){ jump.stop(); } // We are moving down else { setY(other.getY()-getHeight()); setVelocityY(0); onground = true; } } } } The problem is that the object jumps well but does not fall when moved out of platform. Here's an image describing the problem. I know I'm not checking underneath the object but I don't know how. The map is a list of objects and should I have to iterate over all the objects??? Thanks
