  • Is there a LOGO interpreter that actually has a turtle?

    - by Tim Post
    This is not a repeat of the now infamous "How do I move the turtle in LOGO?" Recently, I had the following conversation with my five year old daughter: Daughter: Daddy, do you write programs? Me: Yes! Daughter: Daddy, what's a program? Me: A program is a set of instructions that a computer follows. Daughter: Daddy, can I write a program too? Me: Sure! This got me scrambling to think of a very basic language that a five year old could get some satisfaction from mastering rather quickly. I'm ashamed to admit that the first thing that came to mind was this: 10 INPUT "Tell me a secret" A$ 20 PRINT "Wow really? :" A$ 30 GOTO 10 That isn't going to hold a five year old's attention for very long and it requires too much of a lecture. However, moving a turtle around and drawing neat pictures might just work. Sadly, my search for a LOGO interpreter yielded noting but ad ridden sites, flight simulators and a whole bunch of other stuff that I really don't want. I'm hoping to find a cross platform (Java / Python) LOGO interpreter (dare I call it simulator?) with the following features: Can save / replay commands (stored programs) Has an actual turtle Sound effects are a plus Have you stumbled across something like this, if so, can you provide a link? I hate to ask a 'shopping' sort of question, but it seemed much better than "Is LOGO appropriate for a five year old?"

  • Problem with sound driver

    - by JiminP
    I had problem that sound had lag in Flash. (Other than that, there was no problem.) On the internet, I found that installing OSS4 might help me. So I installed OSS4, but there was some problems (no sound on Flash, and couldn't use function key on the laptop - which is quite annoying), so I try to remove OSS4 and re-installing sound modules. After some mess-up, the whole sound was gone. I used Ubuntu for a year, but I don't know how to use the terminal well (All I know is basic commands like sudo, ls, or apt-get).. Now I'm trying to recover by following instructions at this page, but I have some problems... :( When I try to follow instructions: sudo aplay -l finds no sound drivers. find /lib/modules/'uname -r' | grep snd (backtick changed to ' due to code markup) returns nothing. When I try to do sudo apt-get install linux-restricted-modules-'uname -r' linux-generic, it says that it can't find linux-restricted-modules-3.0.0-13-generic package. lspci -v | grep -A7 -i "audio" returns this, which doesn't contain anything about the name of the driver. Writing sudo modprobe sn and pressing tab twice only returns sudo modprobe sn9c102. sudo aptitude --purge reinstall linux-sound-base alsa-base alsa-utils linux-image-'uname -r' linux-ubuntu-modules-'uname -r' libasound2 returns this, and didn't change non of above. sudo apt-get install linux-alsa-driver-modules-$(uname -r) fails because it can't find the package linux-alsa-driver-modules-3.0.0-13-generic. Compiling ALSA driver doesn't work. When I try to make, it says that /lib/modules/3.0.0-13-generic/build/include/linux/modversions.h doesn't exist. I'm using Ubuntu 11.10. Can anyone help me? I can re-install Ubuntu, but I don't want to....

  • What ufw allows/denies by default?

    - by mgibsonbr
    I was accessing a server running Ubuntu 12.04 Server using SSH and managed to lock myself out of it. I'm still wondering how that happened: The firewall was enabled by default; sudo ufw status did not show any rules (but I could SSH to the server normally); I tried explicitly allowing ports 80 and 443 using the commands: sudo ufw allow 80 sudo ufw allow 443 sudo ufw status now showed something like: Status: active To Action From -- ------ ---- 80 ALLOW Anywhere 80 ALLOW Anywhere (v6) 443 ALLOW Anywhere 443 ALLOW Anywhere (v6) (Recalling from memory and seeing some examples; I can't access the server to see the exact output, so I might be mistaken) After logging out of SSH, now I can't log in anymore (connection timeout). What just happened? There were no DENY rules previously (AFAIK), neither I introduced any. How could SSH be previously available and now it's not? Does ufw (or more precisely iptables) allow everything by default, unless you explicitly allow something, then it denies everything by default? Or did I do something wrong, that broke the existing rules somehow?

  • Suddely internet is not accessible

    - by user189708
    I am going crazy here. One day everything was working fine. I turned pc off and went to sleep. Next day turn pc on and cannot access internet (from any browser). The situation is: I cannot open any webpage from browser (tried Firefox and Epiphany) and cannot receive emails in thunderbird. BUT if I run firefox from console as sudo, I can use it as usual. I can access Skype and pretty much any other network stuff (like installing software with apt-get etc.), also if I use Astrill VPN software I can access webpages even running without sudo. I haven't install any software or anything like that for several days = I have not a clue what could cause this. Just by the way, other Win PC in our home has no issue. Here is what I have tried to fix this: I have tried to restart my pc, router, modem - multiple times I have tried to change permissions to my firefox profile I have tried to completely re-install firefox and start with blank profile, thus no addons I have tried to change /etc/resolv.conf to an IP of my router (it was 127.0.1.1) I have tried to change my hostname (from tomino-NB to tominoNB) I think I might try even more stuff. None of it works. Can someone please try to help me. Thank you UPDATE 1: I have tried this: Removing resolv.conf - Didn't help Also "ping" and "dig" commands cannot resolve host UPDATE 2: I have tried to edit nameservers in resolv.conf but still no effect. I can ping router as well as I can ping outside IP. So definitely just some DNS issue. Is it possible that something is rewriting path to resolv.conf and using different file? UPDATE 3: I have just restarted PC and everything works now... resolv.conf went back to nameserver 127.0.1.1 . I have no clue what happened that it works again...

  • How to recover from terminal custom setup

    - by linq
    I installed ubuntu 12.04 and I added "Terminal" to the launcher bar, the default size of the terminal is a bit small, after some googling here is how I made the disaster change: At HUD menu, type "preference" and I see the option of Edit > preference, this is as I expected After I clicked the option, I forget the exact steps, but somehow I came to some configuration panel and there is a checkbox for terminal "custom" and I checked it now an input box is enabled and I type gnome-terminal --geometry 160x50 Now the problem comes, whenever I click the terminal button at the launcher bar, new terminal windows pops up endlessly from everywhere, I cannot do anything any more except logout or shutdown. The weird thing is, after I come back, I cannot get that Edit > preference any more when I type "preference" in HUD, I tried "Edit", "preference". To be clear, I still can use the computer as long as I do not click that terminal button, but I really want to use terminal to run commands. Help is appreciated greatly! Update - OK, figured out. Go to /home/jibin/.gconf/apps/gnome-terminal/profiles/Default and open that xml file, I can see the options I changed at the GUI, remove them and terminal runs good. The preference HUD is back also, it is actually Profile Preference and it is only available when terminal is open. Continue my ubuntu-ing...

  • Android&ndash;Finding your SDK debug certificate MD5 fingerprint using Keytool

    - by Bill Osuch
    I recently upgraded to a new development machine, which means the certificate used to sign my applications during debug changed. Under most circumstances you’ll never notice a difference, but if you’re developing apps using Google’s Maps API you’ll find that your old API key no longer works with the new certificate fingerprint. Google's instructions walk you through retrieving the MD5 fingerprint of your SDK debug certificate - the certificate that you’re probably signing your apps with before publishing, but it doesn't talk much about the Keytool command. The thing to remember is that Keytool is part of Java, not the Android SDK, so you'll never find it searching through your Android and Eclipse directories. Mine is located in C:\Program Files\Java\jdk1.7.0_02\bin so you should find yours somewhere similar. From a command prompt, navigate to this directory and type: keytool -v -list -keystore "C:/Documents and Settings/<user name>/.android/debug.keystore" That’s assuming the path to your debug certificate is in the typical location. If this doesn’t work, you can find out where it’s located in Eclipse by clicking Window –> Preferences –> Android –> Build. There's no need to use the additional commands shown on Google's page. You'll be prompted for a password, just hit enter. The last line shown, Certificate fingerprint, is the key you'll give Google to generate your new Maps API key. Technorati Tags: Android Mapping

  • Seeking solution for printing-reporting .NET

    - by Parhs
    I am developing an application that prints in separate threads in extreme cases about 20-25 pages per minute to various thermal printers. Currently templates for these are XAML xps documents. All printers have graphics drivers that support EMF/GDI printing. So GDI-EMF is done by operating system resulting in slower performance. Sending raw text for printing is another good solution but doesnt work always , because some clients have old chinese thermal printer that nobody support thus impossible to change codepage / emulation. So it doesnt work always. Also most computers running my software are low end ATOM CPU. So I am thinking to return to GDI, EMF printing and have both Text-Only reports and EMF reports. Another reason i want EMF is because here receipts are signed by Electronic Fiscal Memory device.Most of these dont do good job extracting text from XPS as they dont follow the standard but how windows convert GDI to XPS.Even with text-only mode some of them dont support all character encodings and are impossible to send paper cut command after the sign. I know that using a reporting engine would solve rendering problem but I dont want to buy one. All I want is to be able to show tabular data and insert an image and replaced text.I know there is StringTemplate that could do the generation of template but the problem is i should parse somehow the template and render it using GDI commands. Is there any other solution/approach for this ? Or is there anything ready ?

  • Drivers for Ubuntu 13.10 [on hold]

    - by Fernando De Souza Martins
    I just installed Ubuntu 13.10, my screen resolution is not fitting my screen as the ubuntu interface is all around stretching over the screen, so i thought i might install nvidia's driver that i know can let me adjust the exact resolution i need. So i began a 2 hour quest, i downloaded the driver hoping i would have a wizard to instal it, but yeah, so i tried to do a bit of research and i found that feature, i think its called in english additional drivers, but it wont show the nvidia drivers, i tried the terminal, but once i write the commands i found it asks for a password but i cant type anything once the password is asked. So, my question, obviously, how do i install this driver? I am not sure if this is appropriate, but why doesnt ubuntu have a wizard to install things? I feel like im working for the OS, when it should be the other way around, but i love the concept of linux, so im pushing forward and trying to use it. Another thing is, i had to install a bunch of drivers and applications for the drivers in windows, do i need to install any other driver? I cant change my mouse's sensibility in the os, it seems, so how do i do it? I'm sorry i'm asking all of this, but it seems necessary.

  • Ubuntu-installer fails preseed configuration file

    - by user76171
    I try to install Ubuntu 12.04 over network unattended. I installed a DHCP server (Dnsmasq), a TFTP server (tftpd-hpa), I got the netboot.tar.gz archive with the pxelinux.0 file, the pxelinux.cfg directory, the linux kernel and the initrd.gz image and I put a preseed file into my web server. Dnsmasq, tftpd-hpa, pxelinux and Apache are all on the same machine. The PCs MB doesn’t support PXE, so I use iPXE and boot it from a CD. The PC gets an IP from the DHCP, then iPXE loads #pxelinux.cfg/default, which I edited like this: timeout 5 prompt 0 default install label install kernel ubuntu-installer/i386/linux append vga=normal locale=en_GB setup/layoutcode=sl_SI console-setup/layoutcode=sl_SI netcfg/choose_interface=auto initrd=ubuntu-installer/i386/initrd.gz netcfg/get_hostname=ubuntux preseed/url=#http://192.168.10.10/ins/preseed.cfg Then it loads the linux kernel and the initrd.gz image. Then I got a question: Detect keyboard layout? I desided to bother with this later. So I answer No, and then twice on Englishjust to get trough and then I get to the error: The installer failed to process the preconfiguration file from #http://192.168.10.10/ins/preseeed.cfg. The file may be corrupt. I created the file myself and copied the d-I commands into it. I also tried to get the preseed.cfg over a web browser and it works fine. So why is the installer failing?

  • Apt-get saying "Unable to correct problems, you have held broken packages."

    - by YatharthROCK
    TL;DR: sudo apt-get install ... saying "Unable to correct problems, you have held broken packages." The problem I was trying to get the WebApps feature for PP and QQ following this blog post. I ran the sudo add-apt-repository ppa:webapps/preview command to add the repository, but i got a connection error. Since I know my current ISP gives a shaky connection, I tried again and sure enough, it worked. Then I ran sudo apt-get install unity-webapps-preview, but I realized we had to update apt-get first, so I hit Ctrl + C to stop it. Then I ran sudo apt-get update which worked w/o a fuss, but when I ran sudo apt-get install unity-webapps-preview again later, it showed an error message. Here's the dump: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: unity-webapps-preview : Depends: xul-ext-unity but it is not going to be installed Depends: xul-ext-websites-integration but it is not going to be installed Depends: xul-ext-webaccounts but it is not going to be installed E: Unable to correct problems, you have held broken packages. I think this might be because of me interrupting the earlier command. It hadn't got a chance to output anything, though — I stopped it pretty fast. What I tried I have tried running a number of commands:- sudo apt-get install --fix-broken sudo apt-get autoclean sudo apt-get autoremove sudo apt-get -f install sudoapt-get install ppa-purgeandsudo ppa-purge ppa:webapps/preview` Even after running sudo apt-get upgrade after every try, none of them worked. Research I tried searching Google, looking at a couple of forums and searching on AU, but to no avail. Help would be appreciated.

  • Upgrade from Linux Mint 12 to Kubuntu 12.04?

    - by MountainX
    Is there an "easy" way to "upgrade" my existing Linux Mint 12 install to Kubuntu 12.04 beta 2? I know I could reinstall. Usually I would do a clean install to avoid unexpected issues. But in this case, I don't have time to reconfigure everything from my printers to my installed software, so I am looking for the quick/easy way, but I also want to avoid big risks of an upgrade gone wrong. I'm hoping to just change some repos and run a few commands from the terminal. I don't mind editing a few config files as long as I can find good HOWTOs. But I don't want to be the pioneer (arrows in back). I'm hoping someone has done this before and has a set of steps. For context, I recently installed KDE 4.8 SC onto Kubuntu 11.10 using PPAs. This was on another computer. That wasn't a problem. But I decided to do a fresh install of Kubuntu 12.04 later. I like it well enough that I want to change my other computer from Linux Mint 12 to Kubuntu. (I'm going all-in with KDE. It's now my desktop of choice.) This Linux Mint upgrade will be a move from Gnome and MGSE to KDE, so that will probably complicate things at bit compared to something like upgrading Kubuntu 11.10 to KDE 4.8. References: http://www.psychocats.net/ubuntu/kde Is it safe to install Kubuntu-desktop in 11.10?

  • How do I restore the original color scheme, icons, and theme?

    - by katya sehgal
    I'd like the original colour scheme, icon style of 12.04. I somehow lost the Ambiance theme (possible error or upgrade error). I re-installed 'light-themes' from the terminal and got it back. But the panel on the top that shows the options of sound, battery and wi-fi has changed and I can-not get the original setting back. In the windows, the close, minimize tools have shifted to the right instead of the original left side. I had installed MyUnity and Ubuntu Tweak but deleted them. As such, I want the original setting back. Kindly help me with the commands. I have searched for solutions; there are multiple and I need to be sure if I should follow the same. Kindly bear before marking duplicate. Discoveries: The appearance is gray and boxy as outlined here. Not sure same problem. Similar 'gray and boxy' article here. Desktop forgets theme. I have also tried the unity --reset command. It never completes. I gave it 20 minutes.

  • RPi and Java Embedded GPIO: Java code to blink more LEDs

    - by hinkmond
    Now, it's time to blink the other GPIO ports with the other LEDs connected to them. This is easy using Java Embedded, since the Java programming language is powerful and flexible. Embedded developers are not used to this, since the C programming language is more popular but less easy to develop in. We just need to use a dynamic Java String array to map to the pinouts of the GPIO port names from the previous diagram posted. This way we can address each "channel" with an index into that String array. static String[] GpioChannels = { "0", "1", "4", "17", "21", "22", "10", "9" }; With this new dynamic array, we can streamline the main() of this Java program to activate all the ports. /** * @param args the command line arguments */ public static void main(String[] args) { FileWriter[] commandChannels; try { /*** Init GPIO port for output ***/ // Open file handles to GPIO port unexport and export controls FileWriter unexportFile = new FileWriter("/sys/class/gpio/unexport"); FileWriter exportFile = new FileWriter("/sys/class/gpio/export"); for (String gpioChannel : GpioChannels) { System.out.println(gpioChannel); // Reset the port unexportFile.write(gpioChannel); unexportFile.flush(); // Set the port for use exportFile.write(gpioChannel); exportFile.flush(); // Open file handle to port input/output control FileWriter directionFile = new FileWriter("/sys/class/gpio/gpio" + gpioChannel + "/direction"); // Set port for output directionFile.write(GPIO_OUT); directionFile.flush(); } And, then simply add array code to where we blink the LED to make it blink all the LEDS on and off at once. /*** Send commands to GPIO port ***/ commandChannels = new FileWriter[GpioChannels.length]; for (int channum=0; channum It's easier than falling off a log... or at least easier than C programming.

  • Which language is more suitable heavy file tasks?

    - by All
    I need to write a script (based on basic functions) to process /image/audio/video files. The process is mainly filesystem tasks and converts. The database of files has been stored by mysql. The script is simple but cause heavy tasks on the system; for example renaming/converting/copying thousands of file in a run. The script does not read the content of files into memory, it just manage the commands for sub-processes. The main weight is on the communication with filesystem. The script will be used regularly for new files. My concern is about performance. I am thinking of Shell script a complied language like C Please advise which programming language is more suitable for this purpose and why? UPDATE: An example is to scan a folder for images, convert them with ImageMagick, move files to destination folder, get file info, then update the database. As you can see, the process has no room for optimization, and most of languages have similar APIs for popular programs like ImageMagick, MySQL, etc. Thus, it can be written in any language. I just wish to reduce resource usage by speeding up the long loop. NOTE: I know that questions about comparing languages are not favorable, but I really had problem to choose, because the problems can appear in action.

  • Script/tool to import series of snapshots, each being a new revision, into Subversion, populating source tree?

    - by Rob
    I've developed code locally and taken a fairly regular snapshot whenever I reach a significant point in development, e.g. a working build. So I have a long-ish list of about 40 folders, each folder being a snapshot e.g. in ascending date YYYYMMDD order, e.g.:- 20100523 20100614 20100721 20100722 20100809 20100901 20101001 20101003 20101104 20101119 20101203 20101218 20110102 I'm looking for a script to import each of these snapshots as a new subversion revision to the source tree. The end result being that the HEAD revision is the same as the last snapshot, and other revisions are as numbered. Some other requirements: that the HEAD revision is not cumulative of the previous snapshots, i.e., files that appeared in older snapshots but which don't appear in later ones (e.g. due to refactoring etc.) should not appear in the HEAD revision. meanwhile, there should be continuity between files that do persist between snapshots. Subversion should know that there are previous versions of these files and not treat them as brand new files within each revision. Some background about my aim: I need to formally revision control this work rather than keep local private snapshot copies. I plan to release this work as open source, so version controlling would be highly recommended I am evaluating some of the current popular version control systems (Subversion and GIT) BUT I definitely need a working solution in Subversion. I'm not looking to be persuaded to use one particular tool, I need a solution for each tool I am considering as I would also like a solution in GIT (I will post an answer separately for GIT so separate camps of folks who have expertise in GIT and Subversion will be able to give focused answers on one or the other). The same question but for GIT: Script/tool to import series of snapshots, each being a new edition, into GIT, populating source tree? An outline answer for Subversion in stackoverflow.com but not enough specifics about the script: what commands to use, code to check valid scenarios if necessary - i.e. a working script basically. http://stackoverflow.com/questions/2203818/is-there-anyway-to-import-xcode-snapshots-into-a-new-svn-repository

  • SFTP permission denied on files owned by www-data

    - by Charles Roper
    I have a pretty standard server set up running Apache and PHP. An app I am running creates files and these are owned by the Apache user www-data. Files that I upload via SFTP are owned by my own user charlesr. All files are part of the www-data group. My problem is that I cannot modify or overwrite any of the files via SFTP which are owned by www-data, even though charlesr is part of the www-data group. I can modify the files no problem via a SSH session. So I'm not sure what to do. How do I give my SFTP session permissions to modify www-data owned files? For a bit of background, these are the notes I wrote for myself when setting-up the server: Now set up permissions on `/var/www` where your files are served from by default: $ sudo adduser $USER www-data $ sudo chgrp -R www-data /var/www $ sudo chmod -R g+rw /var/www $ sudo chmod -R g+s /var/www Now log out and log in again to make the changes take hold. The previous set of commands does the following: 1. adds the current user ($USER) to the `www-data` group; 2. changes `/var/www` to belong to the `www-data` group; 3. adds read/write permissions to the group that `/var/www` belongs to; 4. sets the SGID bit on `/var/www`; this final point bears some explaining. And then I go on to explain to myself what setting the SGID bit means (i.e. all files created in /var/www become part of the www-data group automatically). Btw, nothing feels sweeter than going back and reading your own detailed notes on the what, how and why of your own server set up when trying to troubleshoot like this - I recommend it highly to all beginners like myself :-)

  • From TFS to Git

    - by Saeed Neamati
    I'm a .NET developer and I've used TFS (team foundation server) as my source control software many times. Good features of TFS are: Good integration with Visual Studio (so I do almost everything visually; no console commands) Easy check-out, check-in process Easy merging and conflict resolution Easy automated builds Branching Now, I want to use Git as the backbone, repository, and source control of my open source projects. My projects are in C#, JavaScript, or PHP language with MySQL, or SQL Server databases as the storage mechanism. I just used github.com's help for this purpose and I created a profile there, and downloaded a GUI for Git. Up to this part was so easy. But I'm almost stuck at going along any further. I just want to do some simple (really simple) operations, including: Creating a project on Git and mapping it to a folder on my laptop Checking out/checking in files and folders Resolving conflicts That's all I need to do now. But it seems that the GUI is not that user friendly. I expect the GUI to have a Connect To... or something like that, and then I expect a list of projects to be shown, and when I choose one, I expect to see the list of files and folders of that project, just like exploring your TFS project in Visual Studio. Then I want to be able to right click a file and select check-in... or check-out and stuff like that. Do I expect much? What should I do to easily use Git just like TFS? What am I missing here?

    The title of this post is interesting and something I am wishing you and your colleagues had a better way to do. I understand as I am asked this question frequently. I couple of weeks ago I was asked the same question by a customer who documents their database using the ApexSQL Doc tools which uses the extended properties on objects to create automated documentation. I thought that was super interesting and went down the path to see how we could could support the creation of this documentation while leveraging the Visual Studio 2012 SSDT Tools. What I found is was rather intriguing. There is a property called “Description” on all objects in the SSDT tools. This property is rather subtle and I am betting overlooked. To be honest, this property has probably been there for a while and I just never discovered it. Adding text to this '”Description” property it allows Visual Studio to create the commands for the extended properties directly to your schema which should be version controlled. As I did more digging there seemed to be extended properties at every level in the SQL database objects. This fills some rather challenging gaps and allows organizations to manage SQL Schema using the Visual Studio SQL database tools while allowing a way to automatically document the database. This will also work in the automation of the creation and alter scripts that can be generated as part f an automated build system. Now we essentially get a way to store, build and document the database in a nice little ALM package. Happy Coding!

  • XF86 keybinds in Openbox

    - by vasa1
    Lubuntu uses Openbox as its window manager. ~/.config/openbox/lubuntu-rc.xml is a file that specifies, among other things, keybinds for various commands. Most of the keybinds in lubuntu-rc.xml use modifier keys such as Control, Shift, Alt, and Super. For example, one way of opening a terminal window would be by pressing Control+Alt+T together: <!-- Launch a terminal on Ctrl + Alt + T--> <keybind key="C-A-T"> <action name="Execute"> <command>lxsession-default terminal</command> </action> </keybind> But there is also this: <!-- Keybinding for terminal button--> <keybind key="XF86WWW"> <action name="Execute"> <command>lxsession-default terminal</command> </action> </keybind> <keybind key="XF86Terminal"> <action name="Execute"> <command>lxsession-default terminal</command> </action> </keybind> What are keybind key="XF86WWW" and keybind key="XF86Terminal"? How do I locate these keys on my laptop's keyboard? My laptop is a Dell Inspiron N 1545 from 2008.

  • How do they keep track of the NPCs in Left 4 Dead?

    - by f20k
    How do they keep track of the NPC zombies in Left 4 Dead? I am talking about the NPCs that just walk into walls or wander around aimlessly. Even though the players cannot see them, they are there (say inside rooms or behind doors). Let's say there's about 10 or so zombies in a hallway and inside rooms. Does the game keep all of those zombies in a list and iterate through giving them commands? Do they just spawn when the user is within a certain radius or reached a special location? Say you placed the 4 units (controlled by players) on completely different places throughout the map. Let's assume you aren't being swarmed and then you have not killed any of these aimless NPCs. Would the game be keeping track of 10 x 4 = 40 zombies in total? Or is my understanding completely off? The reason I ask is if I were to implement something similar on a mobile device, keeping track of 40 or more NPCs might not be such a great idea.

  • How do I get Graphics drivers / bluetooth / card reader working on an Acer Aspire V3-571G?

    - by Adam
    A couple of days ago I bought an Acer Aspire V3-571G laptop without a system installed on it. The only thing that was there was Linux Linpus. I created a bootable CD with Ubuntu 12.04 64-bit - I read that my processor was 64 bit and that it might be a good configuration for my gear (I'm not especially fluent with all the computer stuff, still trying to learn) and replaced Linpus with Ubuntu. Everything seemed to work fine, but there're few exceptions to that which came pass my way. My bluetooth doesn't work. It seems to be switched on, but when I check my system settings the button is actually off, and I can't drag it 'perminently' to the 'on' position. Tried a couple of commands I found on the net, none of them helped and there was no word whatsoever in my BIOS settings about enabling bluetooth. My card reader has some serious problems with copying more than one file at a time. I tried to put some music on my phone through a MicroSD card adapter (because my bluetooth doesn't work) and it got stuck every single time I copied an album on it. I'm not sure if all my drivers were properly installed, so I checked in the terminal if it could tell me sth about my graphics. typed: sudo lshw -c display and what i got was: *-display UNCLAIMED description: VGA compatible controller product: NVIDIA Corporation vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller cap_list configuration: latency=0 resources: memory:b2000000-b2ffffff memory:a0000000-afffffff memory:b0000000-b1ffffff ioport:2000(size=128) *-display description: VGA compatible controller product: Ivy Bridge Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:44 memory:b3000000-b33fffff memory:c0000000-cfffffff ioport:3000(size=64) As I said I'm no expert and not english-speaking generally, but it doesn't seem to be right. I've got a NVIDIA GeForce GT 640M.

  • My laptop with Linux/ Ubuntu isn't working

    - by Andy Campos
    I have a dell laptop with ubuntu linux. A day I tried to start it up and a black screen just appeared that says: GNU GRUB version1.98+20100804-5ubuntu3 (and these clickable options:) -Ubuntu, with Linux 2.6.35-22-generic -Ubuntu, with Linux 2.6.35-22-generic (recovery mode) -Memory test (memtest86+) -Memory test (memtest86+, serial console 115200) When I click the first one, a bunch of text appears like: mount: mounting /dev/disk/by-uuid/8396a225... failed: invalid argument mount: mounting /dev on /root/dev failed: no such file or directory mount: mounting /sys on /root/sys failed: no such file or directory mount: mounting /proc on /root/proc failed: no such file or directory Target file system doesn't have requested /sbin/init No init found. Try passing init= bootarg Enter 'help' for a list of built-in commands BusyBox v1.15.3 (Ubuntu 1:1.15.3-1ubuntu5) built-in shell (ash) (initramfs) When I enter 'help' a bunch more incomprehensible text appears. Whenever I press the enter key all that pops up is (intetramfs) If anyone can make rhyme or reason out of this please, please help me out so it can boot up normally and i can be set. If there's some kind of special code I have to type in or something I know nothing about computers.
