  • Artificial Intelligence implemented in x86 Assembly? [closed]

    - by Bigyellow Bastion
    Okay, so I decided that for my upcoming operating system, I do basically everything in x86 Assembly, using only 16-bit mode. I will need to write the software to host on it once I have something up and going, and I'll definitely post the source and VM-executable file. But as for now I'm stuck with the idea of implementing the AI code for some of the games I'm making to host on it. AI in Assembly is tedious, and sometimes almost impossible seeming, especially complex AI(I'm talking SNES Super Mario World 2: Yoshi's Island AI here, by the way, not pong AI). I was thinking that it'd be such a hassle that I'd have to bring a higher-level language to work some of this out here, like maybe C++ or C#, but I'd have to go through more work linking it into a fine binary that my OS will host, and that adds unnecessary work to the table I wanted to avoid(I don't want a complex system, I want everything as bare-bones as possible, avoiding libraries, APIs, and linkable formats for now, to make everything more directly accessible to the kernel's API).

  • Ubuntu boots up maintenance shell?

    - by Andrew
    Any time I try to start up my computer it goes to a screen titled GNU GRUB version 1.99-12ubuntu5 I can then choose from 5 different options. If I try to just boot Ubuntu, with Linux 3.0.0-20-generic it then goes to a screen saying: mountall: /lib/x86_64-linux-gnu/libc.so.6: version 'GLIBC_2.14' not found (required by /lib/libply.so.2) General error mounting filesystems. A maintenance shell will now be started. CONTROL-D will terminate this shell and reboot the system. root@Brown126:~# Control-D just brings me back to the first screen. And nothing works in recovery mode. How can I fix this?

  • Recommended: git-completion.bash

    - by andy.grover
    If you use git on a daily basis like I do, git-completion.bash is a great way to make your life a little easier. While I guess it does add tab-completion for git commands, the most useful feature for me is the ability to put the current branch into the cmdline prompt. Now that I am comfortable working with multiple git branches and remotes, a little reminder where I am prevents time-consuming mistakes. git-completion.bash lives in git's git tree.git clone git://git.kernel.org/pub/scm/git/git.gitcopy git/contrib/completion/git-completion.bash to ~/.git-completion.shFollow the instructions in the file to set up, and enable showing branch in $PS1I also use this alias in my ~/.gitconfig, which is convenient:[alias]        log1 = log --pretty=oneline --abbrev-commitHave fun!

  • no back light on my acer aspire 5734z

    - by Dave
    I installed Ubuntu (12.04) on my acer aspire 5734z and the back light stopped working. I have tried the fix by editing the grub file posted on here a couple of days ago but that hasn't fixed it. I have also looked for hardware drivers but that didn't get me anywhere. When I hook up an external monitor it works fine but i have been unsuccessful getting the laptop display to light up. Thanks edit removed link I found a fix here " http://crunchbanglinux.org/forums/post/66562/#p66562 " if anyone has a better fix than the one in that post, let me know.

  • How to enable Mic in Wine (pulseaudio)

    - by Postadelmaga
    I'm not able to make mic work with wine 1.5 I found some suggestions but they don't seem to work: -Disable winepulse.drv (aka: PulseAudio): "A1: Go to winecfg, in the tab 'libraries', enter 'winepulse.drv' in the box and click on add, click yes on the warning. Select winepulse.drv and change load order to 'disabled'. Now try to trigger your bug again, if it was a winepulse bug it shouldn't trigger any more. A2 (easier and preferred): From 1.5.3 onward, launch your program with WINENOPULSE=1 wine program.exe to temporarily disable winepulse for that program." reference: http://ubuntuforums.org/showthread.php?t=1960599

  • Getting Wacom Bamboo Pen + Touch pressure sensitivy in GIMP

    - by Bart van Heukelom
    I've installed my Wacom Bamboo Pen + Touch (CTH-460) in Ubuntu (at least on one system, not another) and the pen works well for controlling the mouse cursor. However, I can't get pressure sensitivity to work in GIMP. I have 4 extra devices in the input devices settings screen now, two of which are the pen and eraser. I've set them both from Disabled to Screen, and left the default settings intact. However, after saving I still don't see any pressure options in the brush tool's options. I've also tried setting the mode to Window instead, but it makes no difference regarding pressure sensitivity. There are no other modes. The pressure works out-of-the-box in Blender (grease pen) so it must be something in GIMP. What can be wrong? Why don't the options appear? How can I debug this?

  • How to prevent WLAN connection from dropping permanently on a Fritz USB WLAN N stick?

    - by Chris
    I have a desktop with a Fritz USB WLAN N stick and tried Ubuntu 12.04. Installation went fine and WLAN is working. However, connection drops permanent. Reconnecting manually fixes it but after a few minutes it drops again. It's connected to a Vodafone 802 box with WLAN N fix set. It seems that it works when I switch off N mode. But I need to test. Can someone confirm this issue or is there another solution? I have another machine with 12.04 (HP 625 laptop) running where connection is stable.

  • Installing Microsoft VX1000 webcam

    - by KRistian
    I found a tutorial with people saying it works; here are the instructions I followed. I opened a shell as root on my system and launched the following: wget http://linuxtv.org/hg/v4l-dvb/archive/tip.tar.gz tar zxvf tip.tar.gz cd v4l... (whatever the newly created directory name is) make all sudo make install Then I edited /etc/modprobe.d/blacklist-custom and added blacklist sn9c102. After reboot, I launched sudo gstreamer-properties. However when I type tar zxvf tip.tar.gz it displays: tar: You may not specify more than one `-Acdtrux' or `--test-label' option Try `tar --help' or `tar --usage' for more information. Why? How can I do this? Thanks in advance.

  • Dual Boot Ubuntu 12.04 on a Thinkpad T420 but keep recovery partition

    - by The PC Samurai
    I have a Thinkpad T420 which runs on Windows 7 Pro and I would like to install Ubuntu 12.04 on it via Dual Boot. But the thing is, I'd like to keep the Thinkvantage Recovery Partition. I've been researching and found this: Install Ubuntu on ThinkPad, recovery section must remain intact and http://www.thinkwiki.org/wiki/Rescue_and_Recovery But the information doesn't seem to be updated for for my situation (the second link indicates that it won't work with Windows 7). Just wonderin' if anyone already has experience doing this? I could create recovery CD/DVD's but I'll be more happy i can keep recovery partition and boot information on the hard drive functional (for future resale purposes). Any Ideas?

  • Installing old Loki games on 12.04 64-bit results in no audio

    - by FlabbergastedPickle
    All, Here's an interesting problem. I followed instructions provided online for installing Loki Games' Heroes of Might and Magic 3 (see http://www.swanson.ukfsn.org/loki/ and http://wtanaka.com/node/7641) and got it installed and patched to the latest version. However, every time I start it regardless whether the pulseaudio is running, I get the following error: LD_LIBRARY_PATH=/usr/local/lib/Loki_Compat/ /usr/local/lib/Loki_Compat/ld-linux.so.2 /usr/local/games/Heroes3/heroes3.dynamic ALSA lib conf.c:3314:(snd_config_hooks_call) Cannot open shared library libasound_module_conf_pulse.so ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM default Couldn't open audio: My first soundcard is HDMI output and my second one is the actual soundcard (HP DM1 running 12.04 64-bit with latest updates). I did set up /etc/asound.conf as follows: asound.conf pcm.!default { type hw card 1 } ctl.!default { type hw card 1 } So, the default soundcard should work ok. Between Shadowgrounds that also stopped working and this it appears a there may be some unfinished business/regressions in 32-bit support on 64-bit systems in 12.04. Any thoughts?

  • Display in applications on ubuntu 12.10 is broken - maybe theme problem

    - by Aleksandar
    I have a problem which looks like this: http://s16.postimage.org/yjusy9en9/Screenshot_from_2012_10_28_22_49_07.png If you take a look at buttons "Apply", "Reset", "Close" or any other buttons or drop-downs, you will see there is no style on them. It is a fresh install of ubuntu 12.10 and it was working on the beginning. But after some time setting up ubuntu I noticed the style on the elements has gone - I don't know when. I installed compiz-settings - maybe that caused - but when I un-install nothing changes. Also checking/unchecking "window decoration" in compiz doesn't help. Please help me. I am out of options :/

  • Is my Document Type Definition Still Up to Date?

    - by Sam
    Hi folks, currently all my php generated rich html webpages start with this line, which I have been adding to my tempaltes YEARS ago... <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Am I still up to date and 2011-proof? or Should I be changing this into something fasterloaden/more agile/more flexible? I have heard of XHTML 1.1. When I remove this line all still works fine. Is it very much needed still? What are my alternatives? Thanks very much for your suggestions.

  • /etc/X11/xorg.conf doesn't exist?

    - by BBetances
    I'm trying to get my video card properly setup to handle 3D acceleration. After searching a bit, I've come across a few howtos that tell me I need to edit my xorg.conf file. That file doesn't exist. X.org is installed by default, I'm sure, and I figured this video card would be widely supported. 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) Any ideas on how I can get this to work properly and play Starcraft II? Or any game for that matter? No resolution problems or anything, just no 3D rendering.

  • Working with CPU cycles in Gameboy Advance

    - by Preston Sexton
    I am working on an GBA emulator and stuck at implementing CPU cycles. I just know the basic knowledge about it, each instruction of ARM and THUMB mode as each different set of cycles for each instructions. Currently I am simply saying every ARM instructions cost 4 cycles and THUMB instructions cost 2 cycles. But how do you implement it like the CPU documentation says? Does instruction cycles vary depending on which section of the memory it's currently accessing to? http://nocash.emubase.de/gbatek.htm#cpuinstructioncycletimes According to the above specification, it says different memory areas have different waitstates but I don't know what it exactly mean. Furthermore, what are Non-sequential cycle, Sequential cycle, Internal Cycle, Coprocessor Cycle for? I saw in some GBA source code that they are using PC to figure out how many cycles each instruction takes to complete, but how are they doing it?

  • OpenOffice doesn't work

    - by dn.usenet
    I installed OpenOffice on 12.04, and set it as the default utility for spreadsheets, but it doesn't run at all. While trying to troubleshoot, I read that it is not recommended to install it alongside LibreOffice. I am about to uninstall OpenOffice because I don't know how to get it working, and LibreOffice is opening my spreadsheet just fine. But just out of curiosity, I also read that I should try deleting .openoffice.org folder; but from where? I don't see it under /usr/lib, nor under my /home.

    I want to install a 27KB lens( reddit-lens: here ) & this "apt-get update" is going to download 20MBs(!) of data for the same. I want to avoid this update bcoz i am on a limited bandwidth connection. I also tried to install .deb file(27KB) for this lens but it says "dependancy is not satisfiable gir1.2-unity-3.0". I went on to http://www.pkgs.org to get that package & there is no version available for ubuntu 12.04. What should I do? Can i install softwares without updating cache? Is that update necessary? Also installation of some softwares requires updating cache while others dont, why?

  • Disable plugin in Firefox (acroread)

    - by cboettig
    I installed acroread from the repositories, and it has decided it should be the default plugin in Firefox, such that when I click on a pdf, it opens in a Firefox window. Unfortunately, it does not display (at least when in dual head mode). This should be simple, but I cannot disable the plugin. Under Firefox Edit - Preferences- Applications - pdf is set to "always ask" so I don't know why it uses acroread in the first place. Under Tools - Manage Content Plugins I see acroread is selected for pdf content. I have the option in the dropdown to search for a new plugin, but not to simply download the file. Typing about:config into the Firefox toolbar gives me a list of configuration options, but does not mention plugin.disable or acroread anywhere. How do I disable the plugin? I have Firefox 11.0 on Ubuntu 11.10

  • How to stop gecko-mediaplayer from buffering endlessly?

    - by mario
    I'm using the gecko-mediaplayer plugin (formerly "mplayerplug-in"). The totem plugin was not always working correctly with Opera, and I'm actually depending on the [Copy URL] feature of gecko-mediaplayer. However that plugin does some inept buffering of videos. It seems to default to 20% caching regardless of what you set in the preferences window. This is quite annoying for big video files. But appearantly it's by design http://groups.google.com/group/gecko-mediaplayer/browse_thread/thread/b7f0f5a3cedc8979 The Gentoo forums listed some workaround http://forums.gentoo.org/viewtopic-t-816690.html - but ~/.config/gecko-mediaplayer/gecko-mediaplayer.conf is not working in the Ubuntu version. Does anyone know the actual way to configure the cache= size. Which is the real configuration filename under Ubuntu?

  • Grub-Efi wrong resolution

    - by Nikki Kononov
    My question, as it comes from the title, related to grub, but it's a different thing. I re-installed Windows 7 and Ubuntu 12.10 in UEFI mode (before that I was using normal BIOS) and everything went perfectly fine. Both systems load as they should but there is one thing that keeps bothering me. The problem is before I installed both systems in UEFI I used to boot in both system using common grub (non-uefi) and resolution in this grub was correct (which is 1366x768). Right now with grub-efi I have wrong resolution (which is seems to be 640x480). So my question is can can I safely set grub-resolution using grub config files or issue is related to something else? (for instance graphics card). I am using Ubuntu 12.10 Intel HD 3000 + Nvidia GT 540M Optimus (I am using bumblebee) Kernel 3.5.0-19-generic all updates installed! I also added ubuntu x-swat ppa for drivers. Thank you for your help!

  • Google not recognizing microdata? [duplicate]

    This question already has an answer here: How long for data highlighter mark up to appear in structured data tool? 2 answers I put in microdata to one page of a site I help manage using schema.org. Using the Google webmaster tool test, the page checks out and displays what it sees as the microdata properly. But when I go to the Structured Data page in webmaster tools, it keeps saying the site does not have any. I put it in 2 weeks ago. Us it just something that take a while for it to recognize? Or does microdata have to be on every page for it to be recognized or something?

  • Serverside memory efficiency and threading for a turn based game

    - by SkeletorFromEterenia
    Im programming on a turn based war-game for some years now (along with the engine) and Im having quite a hard time at figuring out what the games server architecture should look like, since most game server architecture articles I found focus either on FPS oder MMOGs, which doesn't really fit since I want many matches with 1- 16 players on my server, with each match being played in turn based mode. My chief concern is memory usage, since the most basic approach of loading every game that is being played completely into RAM should be quite inefficient, so is there a suitable strategy for selecting only the needed bits and loading them? Another question I got is how to design the threading on the server, since I think using only a single thread could be a problem due to the fact that the game or part of it might have to be loaded from the database. I would be very happy if you could share your knowledge or point me to material on this topic.

  • What is bootstrap listener in the context of Spring framework?

    - by jillionbug2fix
    I am studying Spring framework, in web.xml I added following which is a bootstrap listener. Can anyone give me a proper idea of what is a bootstrap listener? <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> You can see the doc here: ContextLoadListener Bootstrap listener to start up and shut down Spring's root WebApplicationContext. Simply delegates to ContextLoader as well as to ContextCleanupListener. This listener should be registered after Log4jConfigListener in web.xml, if the latter is used. As of Spring 3.1, ContextLoaderListener supports injecting the root web application context via the ContextLoaderListener(WebApplicationContext) constructor, allowing for programmatic configuration in Servlet 3.0+ environments. See WebApplicationInitializer for usage examples...
