  • Execure a random command from .txt file?

    - by Alberto Burgos
    I have a Ubuntu server, and I'm trying to print a Twitter quote using the app "twidge". So I made a list of tweets on a .txt file. I want to print one tweet (per line) from that file and send it to Twitter via twidge (or what ever other method was possible). I can print a random phrase with shuf: shuf -n 1 /var/www/tweets.txt and it works. It sends me back one of the tweets, but, it does not send it to Twitter, even if the "in line" phrase is a command. i.e: twidge update "bla bla bla" It just prints on the screen, but don't send it to Twitter. I tried turning the .txt to .sh, but don't work... any idea? by the way, i want to use it with crontab, something like this: 15 * * * * shuf -n 1 /var/www/tweets.txt

  • How to drag from a background window to the front window

    - by Luis Alvarado
    Is the following I will explain possible with a key combination? Here is the image: As you can see, the terminal is the focus window (Front window) and Nautilus is in the background (Back Window). How can I grab a folder or file from Nautilus without loosing focus on the terminal (Without making the terminal go to the background and Nautilus to the front) and drop it in the terminal?. What I want is not to have to ALT+TAB again just to do this. Options like resizing the windows to fit the screen are not what I am looking for. Like in the image, we have a fullscreen window that we want it to stay like that. We can drag the terminal window around but anytime I access the background nautilus window, I should not loose focus on the terminal (It should not go to the background every time I access Nautilus). Maybe like a key combination that freezes the current focus windows positions and I can drag from background windows to background windows or background windows to the front focused one.

  • Basics of drawing in 2d with OpenGL 3 shaders

    - by davidism
    I am new to OpenGL 3 and graphics programming, and want to create some basic 2d graphics. I have the following scenario of how I might go about drawing a basic (but general) 2d rectangle. I'm not sure if this is the correct way to think about it, or, if it is, how to implement it. In my head, here's how I imagine doing it: t = make_rectangle(width, height) build general VBO, centered at 0, 0 optionally: t.set_scale(2) optionally: t.set_angle(30) t.draw_at(x, y) calculates some sort of scale/rotate/translate matrix (or matrices), passes the VBO and the matrix to a shader program Something happens to clip the world to the view visible on screen. I'm really unclear on how 4 and 5 will work. The main problem is that all the tutorials I find either: use fixed function pipeline, are for 3d, or are unclear how to do something this "simple". Can someone provide me with either a better way to think of / do this, or some concrete code detailing performing the transformations in a shader and constructing and passing the data required for this shader transformation?

  • Algorithm for perfect non-binary graph layout

    - by mariki
    I have a complex non-binary graph model. Each tree node can have multiple children&parents (a node can also have a connection to it's "brother"). A node is represented as square on screen with lines to the connected nodes. For that I want to use Draw2D and GEF libraries. The problem I am facing is the graph layout. I need a nice algorithm that can reposition the square nodes and the connections with minimum intersections and also make it symmetric as possible.

  • Suspend/hibernate doesn't work on an Asus Laptop

    - by b1ackjosh
    I'm having issues suspending 11.04 on my new Asus U30sd-XA1 laptop, it's a new laptop on the market and I'm wondering if anyone else has had this issue and maybe have a fix for it. Basically whenever I close or put the laptop to sleep the screen goes black but the video card doesn't actually turn off, then the fan spins up even faster then it was before and gets hot. I did see that some people were having similar issues on other laptops and they set the kernal back. I'm newish to ubuntu and I'm not super comfortable messing with the kernal. If anyone has any other solutions that would be great. I am not using the 520m nvidia driver because it won't load unity after it's installed. I've also heard quite a few bad things about the drivers on the ubuntu forums, so I deactivated the driver.

  • Designing a "Grid" like object that contains game objects

    - by liortal
    I am working on a 2D game, where there's a game "board" on which other game objects are placed. This this is 2D, my starting point was to design a class that will internally use a 2d array for the actual stored game objects. This class could be simply accessed by 2 indices: (i, j) to get game objects on it. My problem is that i have no idea how to make the game "board" "propagate" its data onto its children. Design questions i ran into are: Should the children placed on the board have display properties such as size, screen position? Should the board itself dictate this information? How to update children in case the board changes some of its properties? (position, etc). Should the board be aware of the types of objects stored in it ? I have no idea how similar things such as WPF or other UI frameworks go about organizing a "container like" object that can arrange or apply certain UI properties to its children.

  • How do I handle "Firmware file X not found" stopping bootup?

    - by John Baber
    I recently upgraded my desktop mac to Precise and now can't get past the Ubuntu 12.04 splash page. The splash freezes with [ 19.931097] b32-phy0 ERROR: Firmware file "b43/ucode16_mimo.fw" not found [ 19.9311126] b32-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version. Please carefully read all instructions on this website. written on it This is when I choose 3.2.0-generic from the grub menu. If I choose to load up older kernels, I still get the same thing. How can I make my computer finish booting again? I'm able to ssh into the machine and poke around, but the actual screen freezes at the splash.

  • Cinnamon Settings blank after update

    - by Seth Balmore
    Using Ubuntu 12.04 with the cinnamon desktop, I installed the most recent updates and now when I open "System Settings" the entire window appears as a blank white screen. The headers for APPEARANCE, PREFERENCES, and HARDWARE are present, but the usual icons for *Background, *Hot Corners, *Printers, etc. are no longer visible. Some of these settings can still be altered via the terminal: cinnamon-settings backgrounds cinnamon-settings applets cinnamon-settings mouse and touchpad But other commands, such as cinnamon-settings hot corners are met with an error. This is obviously a problem with cinnamon, so I just want to bring it to attention and find out when they plan on fixing the bug. A workaround can be found on the web, but it seems way to risky to rely on.

  • Cannot boot Win7 after updating to ubuntu 11.10

    - by angryInsomniac
    I had a dual boot setup on my system, with ubuntu 11.04 and Win7. Yesterday I updated ubuntu to 11.10. Now , I cannot seem to be able to load Win7 , I do see an entry for it on the boot menu. I select that entry and then the screen goes black , with everything coming to a standstill. I tried to wait for it to respond but nothing happened. I went through the forums and tried "grub-update" but when I do that , nothing really happens. I am not sure of this , but I get no output from grub for upto 10 minutes ( can grub-update be made verbose ) How can I fix this and get back to booting both OS'es properly ?

  • will Unity have a keyboard shortcut for accessing the "Session Menu" that appears on the panel?

    - by Sam
    I noticed in screen shots of Unity the presence of the "Session Menu" indicator in the right corner of the top-panel. This menu drops down to offer Log Out, Hibernate, Restart, Shut Down, etc. I know the keyboard shortcuts are not complete yet. But are there plans to implement a shortcut for accessing this Session Menu (i.e., so users can log out, restart & shut down without having to use the mouse)? Further, will the shortcut allow navigation through the menu by just typing the first letter of the listed word (e.g., R for restart and S for shut down)?

  • Why does my program stutter so much?

    - by user36322
    I've been very frustrated trying to solve this. I've looked it up, and all the answers are the same: set IsFixedTimeStep = false. This doesn't help me at all, the program is still jittery and stutters. I have absolutely no idea what is going on, can you guys help? Code for movement (objects is a list): speed = Math.Min(speed + (speedIncrement * gameTime.ElapsedGameTime.Milliseconds / 200), maxSpeed); for (int i = objects.Count - 1; i >= 0; i--) { objects[i].rect.Y += (int)(speed * gameTime.ElapsedGameTime.Milliseconds); //Check if the object is past the screen. If it is, remove it if (objects[i].rect.Y > screenHeight) { objects.Remove(objects[i]); } }

  • Grub Rescue Error: Unknown Filesystem

    - by James
    I was trying to dual boot Windows with Linux (linux installed first). I read that it was easier to do so if windows was installed first. So I tried to install windows, by creating a partition for it. There wasn't enough room on the drive so I tried changing the filesystem of my existing partition to support windows. Now whenever I try to start my computer I get the grub rescue screen. I've tried booting from CD and USB with ubuntu and also with windows, but nothing happens. I ran ls in grub rescue and got hd0, (hd0,msdos5), cd (with an install disc inserted), fd0, and fd1. However if I run ls on any of these I receive the error: unknown filesystem. Can anyone help me out?

  • How can I reconfigure the nvidia proprietary drivers from the command line (ssh)?

    - by Mathieu Pagé
    I have a linux HTPC (running XBMC) in my living room. This morning I ssh'ed into the machine and did upgrade it to 10.10. When it finaly resarted it says something about running in low quality graphics and eventually returned to a command line login prompt. I ssh'ed in again and did a sudo reboot now. When it came back on this time the image is rapidly scrolling from the top to the bottom of the screen. I guess the installed driver doesn't quite work with the S-Video port on which the TV is connected. previously it was working right with the nvidia proprietary drivers. How can I install thoses without using the GUI tool that comes with Ubuntu?

  • Problem with text deletion in vi editor

    - by user184256
    When I am writing C code on the vi editor, I am not able to use the backspace keys or my arrow keys to delete or navigate through lines. Some unexpected special characters occur on the screen that is on middle of my code and I am not able to delete them also. If I use my delete key, the whole code gets deleted. I have tried both insert mode using 'i' and 'a'. I am able to manage this situation for C programming by using the text editors but when I am creating LeX and yacc programs, I find this awkward. Can you please help me with this?

  • PC power supply & normal range for voltages reported in BIOS hardware monitor?

    - by Chris W. Rea
    I'm trying to diagnose whether my computer has an ample power supply. Sometimes when I play a video-intensive game, both monitors lose the video signal, even though the computer remains on and sound playing. A theory I have is: the video card isn't getting sufficient power. I can't imagine it's overheating because the machine is well-ventilated and the video card isn't hot to touch when this happens. Anyway, in my PC's BIOS there's a Hardware Monitor page, and among other voltages reported (such as CPU, DRAM, South Bridge, etc.) I can see the following values: 3.3V 3.152V 5V 4.944V 12V 11.872V Are those the voltages used by peripherals? What voltage should I be referencing if I want to know what my video card (PCI Express) is consuming? What is the normal range of values reported for those? My values above appear to be under by approximately 4.5%, 1.1%, and 1.1% respectively. Is that cause for concern? How else should I be determining if my power supply is "right-sized" for my PC and video card, or am I perhaps barking up the wrong tree?

  • GPU On-the-fly encoding of video through Logitech HD Webcam C510

    - by Ashfame
    Originally asked here but I edited that to move this question as a different one on suggestion by a fellow member. I read that I should have a Core2Duo 2.2Ghz for 720p but I have a 2.0Ghz one, would it be possible for me to first record it and then encode it after recording if my processor really start giving issue when doing on-the-fly encoding? I also have a ATI HD 4850 512MB card, if it can help in encoding on-the-fly or is there a chance that my graphics card alone can handle it and those specs were just for a system without a graphics card? I believe so. Also, I got no worries in dealing with console, if I have to do some of the things above in terminal. Other possible significant details: I have a dual screen setup 29" (1360X768) & 22" (1680X1050) which might be using some good power from GPU and I have 2GB DDR2 800Mhz RAM.

  • Wubi downloaded and installed 64bit 12.10 on my 32bit netbook

    - by Troy
    I downloaded the Wubi installer on my atom N450 netbook. When I started up Ubuntu I got an error that read failed to change the mode of /ect/passwd- to 0600. Then while it booted it froze and several strange characters filled the screen. Finally it loaded it ran pretty slow, and I could connect to my router, but not to the internet. Ping 8.8.8.8 showed no server found. So I checked the about computer and it said I was running the 64 bit installation. Now I know that my computer has a low power 32 bit chip and even the Ubuntu iso download suggested a 32 bit installation. So I went to double check and see if I just missed the option for a 32 bit Wubi install and I did not. There was no option. Is there any way to download a 32 bit version of 12.10 through the Wubi?

    Friend gave me her laptop, we agreed on Ubuntu, but I have troubles even booting up live version (see the notebook). I tried 12.04 64bit on USB stick, it does nothing, when I choose booting live version, it just restarts PC. Then I tried 32bit version, it starts loading, but its stuck on loading components, printing on black screen just dots ........... I Googled it, found similar problem - somebody suggested to use older version and then upgrade it. I went through 11.04, 10.04 - 64 and 32 same result. Restart or infinite loading. I did memtest, it showed 4 errors, Windows Vista is running "fine", no "bluescreens" etc. Any ideas what am I doing wrong?

  • Ubuntu 12.04 - after update it boots in command line only (no windows manager)

    - by ZSW
    I have Ubuntu 12.04, which has been working great for me since I installed it a year ago. Yesterday I ran the updates that update manager recommended. (Last time I ran updates before was about a week ago). After the updates were installed, it asked me to reboot. So I rebooted it, and then it stopped at login prompt (as a command line, with no windows). I logged in and tried to manually start the windows manager, and the screen went blank, and stayed blank I waited several minutes, and then turned it off. How can I figure out what is the problem? Which logs should I check?

  • Ubuntu 13.10 - Unity menu very slow and unresponsive

    - by VukBG
    I have a HP G62 laptop with Intel Pentium processor and ATI graphics. Since upgrade to Ubuntu 13.10, my Unity menu is very slow and unresponsive. I am using proprietary driver for my graphics For example, I'm switching between Gimp and Chrome. When I switch to Gimp, I will be stuck with Chrome menu at the top of the screen. It is really annoying and it is just one of many bugs that came up with 13.10. Any ideas? Should I just revert to default driver?

  • How do you initialize networking on a new Xen guest VM?

    - by Marten Veldthuis
    We have a Citrix XenServer setup, and while I personally lean more towards Dev than Ops, I've got an issue that's been bugging me. When you provision a new (Linux/Ubuntu) guest, how do you get it to have the correct IP-address? I'd want my application servers to exist in the range of 10.20.0.0/24, preferably being .1, .2, etc, so I can keep my sanity. I guess that the actual IP-address is something set in Linux itself, and Xen can't touch that, but then what's the best practice for getting it done? If you set up DHCP, don't you just move the problem to getting the adapters the "correct" MAC-addresses? Do you just have to hardcode a large table of MAC-addresses to IP-addresses, and then provision new guests always with the correct MAC-address on the virtual ethernet adapter? What we currently do is have an image of a "app server" that we boot up a new instance of, and then finalize it (with a script) that (among other things) modifies the /etc/networking/interface file to give it the correct IP. But that feels dirty to me, and I feel like surely there must a better way. Please enlighten me?

  • Unity and games don't work on new Thinkpad T420

    - by Clay Smalley
    Here's my setup: Lenovo ThinkPad T420, brand new NVIDIA Graphics Card 4GB of Ram 128GB Solid State Drive Intel Core i5 Processor Given these specs, there's no reason games and Unity shouldn't be working. The strange thing is that both do work when I run from a live USB, but not when Ubuntu is installed to the hard drive. Is there something different with the 3D capabilities of running from the computer as opposed to running from the live USB? Edit: Some more information: When I log in for the first time when running from the hard drive, Ubuntu says "It seems that you do not have the hardware required to run Unity. Please choose Ubuntu Classic at the login screen and you will be using the traditional environment."

  • How to change the terminal to SCO compliant

    - by kaushik
    I have a server in which SCO 5.x is installed. I have several thin clients which were supplied from our head office. Those thin clients have linux pre-installed in them. When we tried to connect to our SCO server, we have found out that the thin client does not support SCO terminal type. So the program (Which is written in Oracle forms) is not working correctly. Lots of function keys stopped working and screen also not getting refreshed correctly. Hence we decided to use Ubuntu Live USB keys in thin clients. Now the problem is how can we change the terminal type to SCO in ubuntu ? Means I want it in the text terminal (Alt+Ctrl+F1,F2...) (Not in xterm...graphical terminal emulators). Does ubuntu support SCO terminal type ?

  • PHP 5.3.2 Upgrade on Windows

    - by mcondiff
    I have a development box running Windows XP, Apache 2.2.15 Mysql and PHP 5.2.6 About a month ago I updated the Apache to the latest version and it went swimmingly. I am not having the same success with upgrading PHP to the latest version. I backed up my PHP directory and then deleted it. Used the Windows Installer for PHP 5.3.2, installed as an Apache 2.2.X module. I can get "Hello World" and phpinfo() to come up but cannot get mysql to connect. I have the extension un-commented in the php.ini and shouldn't really have to touch the Apache httpd.conf file since I didn't change the directory of PHP. Not sure what I'm doing wrong here. I have to get this right and then upgrade the Live Server too so I want to get this down pat. I've tried to use installation guides on the web with no luck. Any info pertaining to this problem would be great. I'm also afraid that the other PHP modules may not load but cannot really tell anything past mysql not working.
