  • What is the best way to exploit multicores when making multithread games?

    - by Keeper
    Many people suggest to write a program, and then start optimizing it. But I think that when it's coming to multithreading with multicore, a little think ahead is required. I've read about using threads, and experienced it myself during some courses at the university (still a student). The big question is simple, but a bit abstract: What thread related steps in game design do I need to take, before implementation? Now trying to be more specific. Let's say, as an example, that I'm making a small board game (like Monopoly) that I want to be multithreaded. My goal Is that this multithreaded game will exploit the best of the multicore system, lets say 4-6 cores (like in i7 processors). My answer to this question at the moment is, one thread for each of these four basic components: GUI User Input / Output AI (computer rival) Other game related calculations (like shortest path from A to B, or level up status change) I'm not an expert (yet!), and I'm sure there are better answers out there. Any suggestion, answer, different approach will be helpful. Some thoughts: Maybe splitting the main database is a good way.. (or total disaster.. )

  • How to write code that communicates with an accelerator in the real address space (real mode)?

    - by ysap
    This is a preliminary question for the issue, where I was asked to program a host-accelerator program on an embedded system we are building. The system is comprised of (among the standard peripherals) an ARM core and an accelerator processor. Both processors access the system bus via their bus interfaces, and share the same 32-bit global physical memory space. Both share access to the system's DRAM through the system bus. (The computer concept is similar to Beagleboard/raspberry Pie, but with a specialized accelerator added) The accelerator has its own internal memory (SRAM) which is exposed to the system and occupies a portion of the global address space (as opposed to how a graphics card would talk to teh CPU via a "small" aperture in the system memory space). On the ARM core (the host) we plan on running Ubuntu 12.04. The mode of operation of communicating between the processors should be that the host issues memory transactions on the system bus that are targeted at the accelerator internal memory. As far as my understanding goes, if I write a program for the host that simply writes to the physical address of the accelerator, most chances are that the program will crash due to a segmentation violation. So, I assume that I need some way of communicating with the device in real mode. What is the easiest way to achieve this mode of operation?

  • Can't change current working directory to external drive in Windows

    - by Tom
    I'm trying to run a program located on an external USB disk using the Windows command prompt. I'm running Windows 7 64-bit (running in VMWare Workstation 8.0.) Here's what happens: I plug in the USB disk and it appears as drive letter 'E' in My Computer. I launch cmd from the start menu. I notice the prompt displays C:\Users\Tom> I type cd E:\ I notice the prompt displays C:\Users\Tom> (cd also yields C:\Users\Tom>) I can explore the drive using explorer.exe just fine, and it is connected according to VMWare Workstation. What am I doing wrong?

  • Vista: "Change date and time" causes permissions error

    - by alexsome
    I double-click on the time in the bottom right to open the date and time panel. Then I click on the "Change date and time..." button (which has a shield) and I get the UAC dialog. I click "Continue", then am presented with an error that reads: Unable to continue You do not have permission to perform this task. Please contact your computer administrator for help. I will mention I have Comodo installed, but I have turned it off to test this out and I get the same results. All that I've found while googling were suggestions to turn UAC off, but I am interested in learning what the actual problem is. Thanks in advance.

  • LiveCD/USB boot issues with Ubuntu 12.04 on blank drive

    - by Richek
    Not sure how common this issue is, or even how badly I may be missing something simple, but I am a first time usuer having some serious problems. Some background: old HDD running Windows 7 developed too many bad sectors and is bricked. I'm attempting to install Ubuntu 12.04 on a fresh 1TB drive by booting from a liveCD USB flash drive. I've not been able to get past the initial menu screen, however, as the process stalls out shortly after selecting an option (both boot from drive and install to drive). I've tried multiple USB drives as well as CDs, modified the boot order, flashed BIOS, and even tried booting with only the flash drive and the keyboard connected with the same results.Typically what I observe is that the OS begins what I think is compliling, listing drivers and components before freezing on one. When the keyboard is plugged in, its the keyboard driver, before I flashed BIOS, it was a BIOS related item, now its an unknown entry. The computer seems to be reading the drive (idicated by USB light flashing or CD drive reving) for roughly 10 minutes with no progress, followed by the drives going quiet. Some spec info: Motherboard: ASUS P5Q Pro, BIOS version 2102 (latest version), Intel chipset CPU: Intel Core 2 Duo E8400 Wolfdale 3.0GHz help would be appriciated!

  • How can I resolve this error when using net start / stop: "The service name is invalid" ?

    - by JosephStyons
    We have a server that hosts a service (I'll call it "tomato"). Up until now, a client pc has been able to start and stop this service. They just double-click a batch file, and inside that batch file is the command net stop tomato or net start tomato They recently got a new physical computer, and now those same commands fail with the error: C:\>net stop tomato The service name is invalid. More help is available by typing NET HELPMSG 2185. What do I need to do to let the client pc start and stop this service remotely? Edit: I mis-remembered the original commands. They were not using "net start" and "net stop" remotely. They were using sc \\server_name start tomato and sc \\server_name stop tomato And those commands to indeed still work.

  • How to measure startup time and order of Windows services on boot?

    - by djangofan
    I am not asking how to measure server startup time here. I am wondering if anyone knows of a tool that can measure and show a graph of the startup time and order of all the windows services during system startup. I saw a software program shown on my local Portland news last week that does this but I am unable to remember what it was called or anything else about it. All I remember is that it was a "tech" news story to help computer users with their computers. So, I know the software exists and I am trying to find it.

  • Bluetooth connectivity

    - by Viniketa
    computer: Samsung All in One PC OS: Windows 7 (up-to-date) BT Radio: Broadcom I have Bluetooth speakers I have successfully used with the system in the past. In fact, I had them set as default speakers so audio would transfer when I turned them on. No longer. Now, they show as 'disconnected'. Asking for connection gives no response. Option to set as default is greyed out. Bluetooth view utility gives an error of 10049 when I try to connect (supposedly, the means an invalid device address). I uninstalled the device and re-installed. No help. Any advice? Thanks in advance.

  • System in low graphics, deleted linux, grub rescue, can't access windows

    - by First timer
    So I'm pretty new to Ubuntu but I managed to install it with no big problems on both my desktop and netbook. When I installed it on my brother's netbook everything went horribly wrong and now I fear the system is close to beyond repair. The problem was first that it said it did not have any space left (seemed ridiculous since it had a lot). Then Ubuntu began booting into a "System is running in low graphics mode error" which I then tried to fix, using all the tips I could find in here but nothing helped. I think the graphics error and lack of space might have been related but I can't be sure. Finally I gave up repairing Ubuntu and went for a reinstall. Shouldn't have done that! I read that I should simply open Ubuntu through a live usb and choose GParted to delete the Linux partitions so I did and rebooted accordingly. Next, I was to install Ubuntu but now I am only given the option to wipe the whole disk for Ubuntu, not install along with windows 7. If I access GParted I can still see the ntfs partitions that hold windows 7 (there are 2: one labeled RECOVERY and another labeled OS and boot) so why can't I access them? Btw. the OS and boot has a little red mark with a warning that 1 cluster is referenced to multiple times, don't know what that means. If I boot without the live usb I am sent directly into a grub rescue "black screen of the computer will follow no orders". Please, I know that the easiest might be to simply wipe the whole thing clean but there are important files and programs on windows 7. Is there a way to just access windows? It is a dell inspiron 1018 mini netbook, so I have no cd input and no windows 7 installation cd.

  • Couldn't pass the signin screen on ubuntu

    - by Amokrane
    I have an issue here with my computer using ubuntu 10.10 on a 64 bits machine. When I start it, I have the login screen, I enter my credentials but instead of starting the session it reloads the login screen again. I checked the disc using fsck and it seems clean. How should I proceed to diagnose and repair this issue? Thanks! [Edit] I went to the log files, this is what I got: auth.log pam_unix (gdm:session): session opened for user amokrane by (uid=0) pam_ck_connector (gdm:session): nox11 mode, ignoring PAM_TTY :0 pam_unix (gdm:session) :session closed for user amokrane messages.log No ACPI video bus found I also took a shot with my camera of the black screen that appears between the two login screens, it says something like: fsck from util-linux-ng 2.17.2 /dev/sdc4 : propre, xxxx files, xxxx blocs Starting AppArmor profiles Skipping profiles in /etc/apparmor.d/disable: usr.bin.firefox Setting sensors limits Starting postgreSQL ... /var/log/Xorg.0.log [ 25.375] (II) intel(0): Modeline "1920x1080"x60.0 172.80 ...

  • How to Create a shortcut to files / folders on a drive with different / changing letters (root)?

    - by Rolo
    I have seen this question asked and answered many times but the location one usually desires to create the shortcut is on the actual drive with the different letters. I would like to create the shortcut on the drive with the permanent letter. So, let me explain further. I have a C Drive and a G Drive. The C Drive is always C and it's on a Windows XP computer. The G drive may be G today, but H tomorrow. How can I create a permanently working shortcut on the C Drive that points to the G, sometimes H, external hard drive? P.S. I am referring to an external hard drive, but I would also (not instead) be interested in the answer if it were a usb flash drive. (Keep in mind the shortcut is being created on the drive with the permanent letter). Thanks.

  • Dualboot (Win 8 / Ubuntu 13) is stuck at 'switching to clocksource'

    - by Daniel Puscht
    for days I have been crawling the web for solutions to my problem, but couln't find any. Here it is: I got a new Laptop (ASUS Vivobook S200E) with Win 8 OEM preinstalled. I wanted to create a dual-boot system with Ubuntu 13 next to it. I read about UEFI and that I have to turn of Secure Boot and use the existing EFI partition as bootloader for Ubuntu. So I did. I also ran boot-repair reinstalling the GRUB. The result is when I start the computer I get into the boot menu. So far, so good. When I pick Win everthing is fine. But when I choose Ubuntu (recovery) the system starts, but gets stuck at the line '[1.806366] Switching to clocksource tsc'. I already tried other versions of Ubuntu (12.04.2, 12.10). I played with boot-repair (using the recommended fix, setting everything manually). But nothing works. It's always the same issue. I read that it could be a problem concerning graphic drivers, but this I can hardly believe. If this is any help, boot-repair gave me this link to post in fora. http://paste.ubuntu.com/5810391/ Thanks for any help in advance

  • Hosting files with support for file tagging / keywords

    - by Zev Chonoles
    I have a large (approx. 25GB) collection of files I would like to host online for people to view or download. I have a spare computer I can use as a dedicated server for these files. I'm looking for a method of, or piece of software for, hosting my files where I can assign tags or keywords to the files, and people viewing my files online can search the collection via the tags. By way of approximate solutions I've found so far, I see that there is software such as Collectorz.com or Readerware for creating databases of one's books / music / movies, and these databases can be searched by tags or keywords, and the databases can be made available and searchable online; this would suit my purposes except that my files are not necessarily books, music, or movies, and I want the files themselves accessible online, not a database describing my files. A commercially-available solution like the ones above would be acceptable, but I'd prefer to have the whole setup under my control (i.e. I'd like to either implement it by hand, or use commercial software that doesn't rely on using the company's servers, paying them a continued fee, etc.). The current extent of my internet experience is designing a few Google Sites, so I know there's a fair chance I won't understand the answers I receive, but I'm always happy to have a summer project :)

  • Installed IE8 & SP3 on XP now I can't HTTPS from any browser

    - by Kevin
    The computer is Windows XP Professional SP3 with IE8. On the Tools Options Connections the "Settings" is GRAYED OUT (I am an admin on the machine) Any browsing of https:// addresses results in IE displaying the following: "this program cannot display the web page" After installing an alternate browser and trying the same https:// address I get a similar error message. I have tried using Compatibility View Settings to for all web pages and this has no effect on the problem. HTTP addresses work fine, I can PING sites such as google.com without issue. Question: What could be preventing me from getting at the settings to check to see if I'm using a proxy? What else could be preventing HTTPS access?

  • AppleTV - itunes store is temporarily unavailable - please check back later

    - by Ken
    When attempting to rent a movie on ATV, my wife received the error message above.  Alternately “server unavailable”.  When your wife is sick, the amount of IT support she needs goes up exponentially.  One piece of the puzzle was that she had changed her Apple ID password.  On her PC I ran iTunes and under account, there was only 1 device listed (not the ATV).  Even when signed out/back-in on the ATV under Settings>iTunes it still gave same error message.  What I suspect is it thinks she is trying to authorize the device to another Apple ID.  Some new 90 day rule limits when a device can be associated with another Apple ID.  Your iTunes store/account will show devices, and how long before they can be associated with a different Apple ID from the Account Information page in iTunes on your computer.  Apple must have no freaking idea why someone would want to know which ID is associated to the ATV (i.e. the vice versa), because it can’t be done. Solution: Try ATV settings>reset I swapped out ATV 1 for ATV 2 (used for music streaming downstairs).  I know it’s a cop-out solution, but remember I had a sick wife breathing down my neck.

  • How can I create an orthographic display that handles different screen dimensions?

    - by Piku
    I'm trying to create an iPad/iPhone game using GLES2.0 that contains a 3D scene with a heads-up-display/GUI overlaid on the top. However, this problem would also apply if I were to port my game to a computer and run the game in a resizable window, or allow the user to change screen resolutions... When trying to make the 2D GUI/HUD work I've made the assumption that all I'm really doing is drawing a load of 2D textured 'quads' on the screen and am trying to treat the orthographic projection as an old-style 2D display with 0,0 in the upper left and screenWidth,ScreenHeight in the lower right. This causes me all sorts of confusion when I rotate my ipad into Landscape mode since I can't work out what to put into my projection and modelview matrices to turn everything around the right way. It also gets messy if I want to support the iPad's large screen, an iPhone or a Retina display since I have to then draw three sets of textures for everything and work out which ones to use. Should I be trying to map the 2D OpenGL co-ords 1:1 with the screen? While typing out this question it occurs to me that I could keep my origin in the centre, still running -1/+1 along the axes. This would let me scale my 2D content appropriately on the different screen sizes, but wouldn't I end up with the textures being scaled and possibly losing quality? I'm using OpenGLES 2.0 and have a matrix library that has equivalents to the GLES1.1 glOrthof() and glFrustrum() calls.

  • Sniff packets using tcpdump

    I have a completely noob question. I want to see all packets that come to my computer from particular site (google.com). So I start tcpdump sudo tcpdump -i eth0 host google.com and enter google.com in a browser and hit enter - nothing gets captured. I can't figure out why it happen. What do I do wrong? Edit It appeared that I was listening to the wrong interface. I had changed eth0 to any and it worked. It was ppp1 that needed listening. Thanks for your answers!

  • Why does HDTune report better performing drives 2 months after installing them?

    - by Rolnik
    OK, so this is really weird. I ran HDTune on a newly set-up home-built computer and got the following readings from my drives in mid-November. SSD 154 MB/s RAID1 87 RAID0 198 (software installs) RAID0 98 Swap drive Today, in January, I run HDTune (same version) and get these results, in MB/s: SSD 186 RAID1 98 RAID0 241 RAID0 98 (Swap drive) Here are more details that HDTune reports on the SSD drive: HD Tune: OCZ-VERTEX Benchmark Blockquote Transfer Rate Minimum : 135.4 MB/sec Transfer Rate Maximum : 219.4 MB/sec Transfer Rate Average : 185.7 MB/sec Access Time : 0.1 ms Burst Rate : 187.3 MB/sec CPU Usage : -1.0% To get to my question: Why are my hard drives improving in performance? Most of my logical drives are in some form of RAID, except for the SSD. Will this performance ever deteriorate? Note, none of my drives are a hybrid drive that uses some form of SSD to enhance the write/reads on actual platters.

  • Can't start firewall or automatic updates in Windows XP

    - by Chris Porter
    On a friends laptop following some viruses infestations there is a problem in starting the Windows firewall. The error is: Could not start the Windows Firewall/Internet Connection Sharing(ICS) service on Local Computer. Error 2: The system cannot find the file specified When attempting to turn on automatic updates in the security centre, the message is: We're sorry. The Security Center could not change your Automatic Updates settings. To try changing these settings yourself, go to System in Control Panel. On the Automtic Updates tab, select Automatic (recommended), and then click OK. All the options under "Automatic Updates" are greyed out.

  • Network router and switch configuration

    - by gilly3
    Can I put a switch before my router in my home network? Here is a diagram of how I want to set up my network: ________________________________ ________________________________________ | | | | | Cable Access Panel | | Home Office | | _____________ ________ | | _____________ | | | | | | | | | | _________ | | | Cable Modem |--->| Switch |-------------->| Router |____| | | | |_____________| |________| | | |_____________| | Printer | | |______________________/____\____| | / | \ |_________| | ___/_ _\___ | _____/ ____|____ \_____ | | | | | | | | | | | | | | PC1 | | PC2 | | | PC3 | | Ext.

My cable modem is located in the far corner of my home where my phone/tv/network access panel is. I'd rather keep the wireless access point in a more central location, but I'm not sure if DHCP will continue to work properly with that configuration. Edit: I'd like to continue to be able to share files and access my networked drive and printer from each computer in the house.

  • SSD I/O extremely slow installing/booting Ubuntu 12.04

    - by Menda
    These are some useful specs: Macbook Pro 7,1 OWC Mercury Extreme Pro 2,5" SATA SSD (120 GB). Has SandForce driver. Ubuntu 12.04 Desktop 32 bits. One 18 GB partition for GNU/Linux and 1.5 GB for SWAP. MD5 for the Ubuntu install CD is OK. I tried to install Ubuntu. It seems that everything is recognized, but there's a big problem: read and writes to the SSD are extremely slow. For example, the install process, which shouldn't take more than 20 minutes, it takes 7 hours. Then, booting up the computer takes about 20 minutes. I checked and the problem is definitely the SSD. Every access to any file is like 10 times slower than normal. I have tried to format the partition as Ext4 and Ext3 with the same problem. Trying to install other distros like Fedora 17, I have a similar problem. There's a "lag" with the SSD, but not so accused as in Ubuntu. Surprisingly, Debian 6.0 installs and works without any problem. Mac OS works pretty good as well in the other partition, so I discard it's an SSD problem. Thanks for your help!

  • Change Win7 taskbar position (overriding GPO, Registry Editor, Admin. Rights)

    - by diegocavazos53
    I run the computer center of my Faculty and the problem is that users manage to change the Win7 taskbar position. I don't really know how they do this as far as I have applied many group policies that are specific to the taskbar (like locking it). I have also disallowed users from entering new registry keys or executing the command prompt (or employing scripts). They have regular user rights and many Win7 tweaking programs need administrator rights to make changes to the GUI. So in other words, the taskbar is locked, there is a policy that sets its position to the lower part of the screen, users can't see the control panel, add registry keys, use the command prompt and don't have admin. rights. How do they keep moving the taskbar position to the upper part of the screen? Any ideas would be greatly appreciated. Thank you.

  • Can I replace my notebook's fan without replacing the heat sink?

    - by kuzzooroo
    My laptop (Acer Travelmate 8204) has started making a grinding noise, which seems to be coming from the fan (not the hard drive). Some articles online mention replacing the fan, but others imply that one should replace both the fan and the heat sink. Does it make sense to replace the fan only? (addendum: does this procedure really take 3 hours for a noob, as this video implies? UPDATE: the fan certainly seems to be on the "top" layer when I open my laptop but some parts of it extend under other layers) Some additional info in response to comments: I have run MS scandisk on the hard drive a few times since the grinding started. It usually reports finding something or other but the computer's behavior doesn't change I'm pretty sure it's the fan based on where the noise is coming from. I employed the cardboard tube trick from the PC World article.

  • Why Can't Computers Off My Network See the Site?

    - by nmagerko
    Have just set up Apache, PHP, MySQL, etc. on my Ubuntu OS, and I was wondering why computers that are not on my network can not see the basic index.html that Apache uses as the default. I set up the static ip address for my computer, and I use 192.168.1.100 for computers to view the simple site. Is there something I am missing that will allow others to access my site? (It is REALLY simple; no graphics, CSS, etc.)
