• Why did Ubuntu and Windows start hanging mysteriously after I took a vacation?

  - by Ashrey Goel

  I installed Ubuntu alongside my Windows 7, after partitioning my HDD using Easeus partitioning manager. It was working perfectly, no problems, no data lost or corruption. Then I went away for 2 days and in my absence I don't know what happened in that period, now both Windows 7 and Ubuntu keep hanging continuously, like when you paint and change a brush it'll hang, I mean on very simple commands and I know my computer does not hang on such petty things. I use it for developing music and the specification are: Model: DELL-XPS Processor: Intel i5, 2.53 GHz RAM/Memory: 4GB Hard disk size: 500GB HDD Windows 7 partition: 417 GB Ubuntu Partition: 50 GB Please Help.

• Ubuntu 10.10 freezes

  - by albert green

  Hi, I have the following configuration: CPU: amd athlon 64bit Motherboard: Phoenix with awardBIOS v6.0 APIC mode = disabled Video card: GeForce 5500 Sound card: soundblaster live 24bit RAM: 1.5GB Partitions: ext3 32GB where I installed Ubuntu. Swap 500MB. 180GB Fat32 unmounted. contains data only. I installed Ubuntu 10.10 and used the "Additional driver" program to get the nVidia proprietary drivers. The system works for sometime and randomly freezes. The mouse and keyboard are not responding and I am not able to do a SSH. The only solution is pressing the power button. I tried Kubuntu 10.10 and 32/64-bits versions as well. There is nothing in the logs to suggest what the reason might be. Any help will be appreciated. Thanks in advance.

• Overheating on Dell Studio XPS 1645

  - by pjtatlow

  So I was wondering if anyone else has come upon this problem, and/or has come up with a solution. When I use my Ubuntu partition, my computer becomes extremely hot, and the fan runs very noisily for a very long time. If I reboot into windows while this is happening, my computer actually begins to cool down while doing the exact same tasks. Thinking this might just be a bug with Ubuntu, I installed fedora on another partition, and the same problem occurs. Is this a problem with the kernel? Cpufreq tells me that my CPU is running at 933 MHz out of a possible 1.6 GHz from my Intel Core i7 CPU Q70. For anyone who wants more information, I have 8 GB of memory, and an ATI Mobility Raedon HD 5730 Graphics Card. I'm open to any ideas anyone might have. Thanks in advance!

• Interacting with scene from controller/app delegate cocos2d

  - by cjroebuck

  I'm attempting to make my first cocos2d (for iphone) multiplayer game and having difficulty understanding how to interact with a scene once it is running. The game is a simple turn-based one and so I have a GameController class which co-ordinates the rounds. I also have a GameScene class which is the actual scene that is displayed during a round of the game. The basic interaction I need is for the GameController to be able to pass messages to the GameScene class.. such as StartRound/StopRound etc. The thing that complicates this is that I am loading the GameScene with a LoadingScene class which simply initialises the scene and replaces the current scene with this one, so there is no reference from GameController to GameScene, so passing messages is quite tricky. Does anyone have any ways to get around this, ideally I would still like to use a Loading class as it smooths out the memory hit when replacing scenes.

• Session Mania: Content Catalog & Suggest-a-Session

  - by Justin Kestelyn

  As ably reported in the Oracle Technology Network blog, the Oracle Develop Conference's content catalog is now public (as are the catalogs for JavaOne and Oracle OpenWorld), meaning you can now explore technical sessions scheduled for the conf to your heart's content."But something's missing", you may tell yourself. "Where is my favorite subject, the one I happen to also be an expert on?" Well, there's good news for you, too: The Suggest-A-Session project has returned. It works thus: Submit a session idea via Oracle Mix and ask your colleagues, Oracle Mix community, friends and anyone else you know to vote for your session. (You must be an Oracle Mix member to vote.) Voting is open through June 20. For the most part, the top voted sessions will be selected for the Oracle Develop Conf (or Oracle OpenWorld) official agenda. See the FAQ for fine print.Apparently some people have already jumped into this loophole, including Oracle ACE Director Marco Gralike, who has "gone video" on us: Why wait? Suggest-a-session!

• front usb wont mount harddrives, internal usb ports do

  - by Thesgsuser

  I have noticed something in my new build, i am using Ubuntu desktop newest version my motherboard is the asus f1a75-m pro R2.0 with the usb ports in the back all my NTFS hard disks or usb sticks work fine, but then.. when i put them in the front usb ports of my chassis (silverstone milo ml-03) they wont mount... I have 2 usb 3.0 ports in front of the case connected with a internal usb 3.0 header. But i verified that the usb 3.0 ports on the back do mount the harddisk so it has nothing to do with usb 3.0 i think. The strange thing is, my mouse works fine on the front usb ports. Every usb hardware piece seems to work except if it has any memory inside it :( What seems to be the problem?

• How is this number calculated?

  - by Hamid

  I have numbers; A == 0x20000000 B == 18 C == (B/10) D == 0x20000004 == (A + C) A and D are in hex, but I'm not sure what the assumed numeric bases of the others are (although I'd assume base 10 since they don't explicitly state a base. It may or may not be relevant but I'm dealing with memory addresses, A and D are pointers. The part I'm failing to understand is how 18/10 gives me 0x4. Edit: Code for clarity: *address1 (pointer is to address: 0x20000000) printf("Test1: %p\n", address1); printf("Test2: %p\n", address1+(18/10)); printf("Test3: %p\n", address1+(21/10)); Output: Test1: 0x20000000 Test2: 0x20000004 Test3: 0x20000008

• The practical cost of swapping effects

  - by sebf

  I use XNA for my projects and on those forums I sometimes see references to the fact that swapping an effect for a mesh has a relatively high cost, which surprises me as I thought to swap an effect was simply a case of copying the replacement shader program to the GPU along with appropriate parameters. I wondered if someone could explain exactly what is costly about this process? And put, if possible, 'relatively' into context? For example say I wanted to use a short shader to help with picking, I would: Change the effect on every object, calculting a unique color to identify it and providing it to the shader. Draw all the objects to a render target in memory. Get the color from the target and use it to look up the selected object. What portion of the total time taken to complete that process would be spent swapping the shaders? My instincts would say that rendering the scene again, no matter how simple the shader, would be an order of magnitude slower than any other part of the process so why all the concern over effects?

• Multiplayer Game Listen Servers: Ensuring Integrity

  - by Ankit Soni

  I'm making a simple multiplayer game of Tic Tac Toe in Python using Bridge (its an RPC service built over a message queue - RabbitMQ) and I'd like to structure it so that the client and the server are just one file. When a user runs the game, he is offered a choice to either create a game or join an existing game. So when a user creates a game, the program will create the game and also join him as a player to the game. This is basically a listen server (as opposed to a dedicated server) - a familiar concept in multiplayer games. I came across a really interesting question while trying to make this - how can I ensure that the player hosting the game doesn't tamper with it (or atleast make it difficult)? The player hosting the game has access to the array used to store the board etc., and these must be stored in the process' virtual memory, so it seems like this is impossible. On the other hand, many multiplayer games use this model for LAN games.

• How to Highlight a Row in Excel Using Conditional Formatting

  - by Erez Zukerman

  Conditional formatting is an Excel feature you can use when you want to format cells based on their content. For example, you can have a cell turn red when it contains a number lower than 100. But how do you highlight an entire row? If you’ve never used Conditional Formatting before, you might want to look at Using Conditional Cell Formatting in Excel 2007. It’s one version back, but the interface really hasn’t changed much. But what if you wanted to highlight other cells based on a cell’s value? The screenshot above shows some codenames used for Ubuntu distributions. One of these is made up; when I entered “No” in the “Really” column, the entire row got different background and font colors.

• Installing Ubuntu Desktop on usb stick

  - by Tobias Gårdner

  trying to install Ubuntu Desktop on a USB stick but I do not succeed. First time I tried, the USB stick contained an installation of USB server and I wanted to start over again. However, it complained about partioning. Removed all the partitions from the stick and tried again, hoping that the installer would help me out with partioning... But now the USB stick did not show up at all... Created one partion NTFS on the USB stick and tried again but the only "automated" alternative I get for installing is to overwrite or add Ubuntu to my HDD which already contains Windows, something that I do not want... Do I need to manually create partions on the stick in the installer? Which partitions should I create? The USB stick is 8GB and the machine that I will test it on has 8GB memory. Helpful for any support here. Regards, Tobbe G
