• How to create a filesystem mountable by windows in linux?

  - by wcoenen

  I have attached an external USB disk to my debian gnu/linux system. The disk showed up as device /dev/sdc, and I prepared it like this: created a single partition with fdisk /dev/sdc (and some more commands in the interactive session that follows) formatted the partition with mkfs.msdos /dev/sdc1 If I then attach the USB disk to a Windows XP or Vista system, then no new drive becomes available. The disk and its partition show up fine in the disk managment tool under "computer management", but apparently the file system in the partition is not recognized. How do I create a FAT32 file system which can actually be used in windows? edit: I've given up on this and went with a NTFS file system created by windows. In debian lenny this can be mounted read-write but apparently it requires you to install the "ntfs-3g" package and explicitly pass the -t ntfs-3g option to the mount command.

• Network card dies when trying to wake up laptop from sleep

  - by Bugmaster

  I have a Dell XPS 1640 laptop (aka Dell Studio XPS 16), running Vista. Whenever the laptop wakes up from sleep, my Broadcomm LAN card immediately dies. Any attempt to access it completely locks up whichever program I use to access it. There appears to be no way to re-awaken the card, other than rebooting; note that Vista does not even shut down properly if some program is waiting for the card. So far, I have tried the following: Disabled the "allow your computer to shut down this device to save power" in the device properties. This had no effect. Attempted to disable and then enable the card in the device properties. No effect. Tried ipconfig /renew: this locks up ipconfig to the point where I can't even kill its process. Force-install updated drivers from broadcomm: no effect. Does anyone have any other ideas ?

• Can I remotely monitor printf results of a C program?

  - by Mota

  I have a long running C program in which I've started from the Terminal.app using: gdb program_name gdb run I'm using many printf statements to monitor the progress of the program. Unfortunately, the screen of the computer has been frozen since yesterday, but the process is still running. My question is, can I watch the progress of the program (i.e. the results of the printf statements) remotely? I'm not that familiar with the terminal, but I know how to ssh and do some simple terminal tasks. The OS of the machine with the frozen screen is Mac OS 10.6.

• Why is Ubuntu unmounting my primary hard drive?

  - by Twisol

  I'm running Ubuntu 10.10 on my laptop (an Asus G73j), dual-booting Windows 7 if that matters. After using the computer for couple of hours or so, I get a popup complaining that a file was unmounted, then my GNOME desktop panels disappear. I can't save any unsaved work (the file browser shows "Filesystem" as totally empty), and other programs break in odd ways (like Chrome can't browse to any new pages, but keeps current ones going... at least I still have Pandora to listen to when this happens!). I've tried looking in the system logs to no avail; I'm assuming that it can't write any errors to the logs because, of course, the logs are on the primary hard drives. This started happening maybe a few days ago. Yesterday I upgraded from 10.4, but I believe it was happening before then. Any advice for figuring this out? EDIT: It just happened again, and I heard a small little clicky sound from the hard drive about five seconds before things went south. I'm thinking I should start backing up ASAP. In response to a comment, here's the dmesg output: http://askubuntu.pastebin.com/uYGshBay Also, the SMART status says the disk has a few bad sectors, and the detailed data says there are 14. It says it passed the self-assessment though. Lastly, this doesn't seem to be happening when I'm on Windows. I recently re-enabled ureadahead (which I disabled ages ago because it was causing Ubuntu to hang at the startup logo), could that be the source of the problem? I've disabled it again to see.

• I shrunk the Windows partition, now it says grub rescue on boot

  - by user1009013

  I have got a machine with dual-boot Windows 7 and Ubuntu 11.10, and I wanted to add another OS to that (Jolicloud), so I started the partition manager in Windows and shrunk the Windows partition by about 10 GB (so now I have:Windows;currently empty 10GB;Ubuntu). I shutted down the computer because I was finished. Now when I started my machine again it says error:no such partition. grub rescue> and I can type commands. ls gives (hd0) (hd0,msdos5) (hd0,msdos4) (hd0,msdos2) (hd0,msdos1) (fd0) if that helps

• What language and topics should be covered when teaching non-CS college students how to program?

  - by michaelcarrano

  I have been asked by many of my non-computer science friends to teach them how to program. I have agreed to hold a seminar for them that will last for approximately 1 to 2 hours. My thoughts are to use Python as the language to teach them basic programming skills. I figured Python is relatively easier to learn from what I have researched. It is also a language I want to learn which will make holding this seminar all the more enjoyable. The topics I plan to cover are as followed: Variables / Arrays Logic - If else statements, switch case, nested statements Loops - for, while, do-while and nested loops Functions - pass by value, pass by reference (is this the correct terms for Python? I am mostly a C/C++ person) Object Oriented Programming Of course, I plan to have code examples for all topics and I will try to have each example flow into each other so that at the end of the seminar everyone will have a complete working program. I suppose my question is, if you were given 1 to 2 hours to teach a group of college students how to program, what language would you choose and what topics would you cover? Update: Thank you for the great feedback. I should have mentioned in my earlier post above that a majority of the students attending the seminar have some form of programming experience whether it was with Java or using Matlab. Most of these students are 3rd/4th year Engineering students who want to get a refresher on programming before they graduate.

• Windows 2008 Server Unable to activate with other methods

  - by matt king

  I'm trying to activate windows 2008 server SP2 today since the activation trial is done. I do not have an internet connection with this server so I can not activate online, and with the other servers in this farm I've been able to run the slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx and then it would open up the activate by phone method and we would just activate that way. I say again, I don't have an internet connection so I can not do the online activate. If I do the slui 4 it brings up the activation window but show me other ways to activate is still greyed out. I've disabled the NIC on this Hyper-V server and I still can not get the other way to activate to show up... Anyone have any ideas? This computer is one of my AD servers so.. it being in notification mode kind of sucks. Thanks.

• How do I interpolate air drag with a variable time step?

  - by Valentin Krummenacher

  So I have a little game which works with small steps, however those steps vary in time, so for example I sometimes have 10 Steps/second and then I have 20 Steps/second. This changes automatically depending on how many steps the user's computer can take. To avoid inaccurate positioning of the game's player object I use y=v0*dt+g*dt^2/2 to determine my objects y-position, where dt is the time since the last step, v0 is the velocity of my object in the beginning of my step and g is the gravity. To calculate the velocity in the end of a step I use v=v0+g*dt what also gives me correct results, independent of whether I use 2 steps with a dt of for example 20ms or one step with a dt of 40ms. Now I would like to introduce air drag. For simplicity's sake I use a=k*v^2 where a is the air drag's acceleration (I am aware that it would usually result in a force, but since I assume 1kg for my object's mass the force is the same as the resulting acceleration), k is a constant (in this case I'm using 0.001) and v is the speed. Now in an infinitely small time interval a is k multiplied by the velocity in this small time interval powered by 2. The problem is that v in the next time interval would depend on the drag of the last which again depends on the v of the last interval and so on... In other words: If I use a=k*v^2 I get different results for my position/velocity when I use 2 steps of 20ms than when I use one step of 40ms. I used to have this problem for my position too, but adding +g*dt^2/2 to the formula for my position fixed the problem since it takes into account that the position depends on the velocity which changes slightly in every infinitely small time interval. Does something like that exist for air drag too? And no, I dont mean anything like Adding air drag to a golf ball trajectory equation or similar, for that kind of method only gives correct results when all my steps are the same. (I hope you can understand my intermediate english, it's not my main language so I would like to say sorry for all the silly mistakes I might have made in my question)

• How can I prevent a Windows laptop from making noise when starting up?

  - by Walkerneo

  I have a Windows 7 laptop here that makes a noise each time it starts up. I know I can disable that noise now that I'm logged on, but how could I have prevented it WHILE logging on? I remember that there was one of the function keys (F8?) that would allow you to boot into safe mode, but is there a key that will stop the startup sound? Imagine, for example, having your laptop in the library when you know the volume is all the way up - how could you log into your computer without disturbing everyone else?

• Single domain user can't install a specific shared network printer

  - by drpcken

  I have a file server serving up shared network printers. Never had any issues in the past. I have a specific domain user (just 1) that gets this error when trying to install a specific printer: You do not have sufficient access to your computer to connect to the selected printer This user can install all the other printers no problem. All my other domain users can install the printer with no problem. I've removed the driver from the local client and tried again but with the same problem. Even as an administrator I get this error. Is there something I'm missing?

• Why is my disk full?

  - by Agmenor

  I installed Ubuntu 12.04 by doing a fresh install where there was previously Ubuntu 11.10. My computer warns me now that my disk is nearly full. After having run apt-get purge, run apt-get autoremove and emptied the Trash can, I still have this problem as shown by this screenshot of Gparted: The disk /dev/sda7 is indeed full. I ran the Disk Usage Analyzer (Baobab) and I am still not sure of what is happening: One of my hypothesis is that when installing Ubuntu 12.04, I didn't configure my disks well and the disk /dev/sda6 is not mounted well as /home. Is this the reason indeed? What should I do to verify this and then to get the things fixed? Here are a few additional details to answer the questions I received (thank you everybody): My home directory is not encrypted. The Backup utility (Déjà Dup) is not set for automatic backups. (I do it myself and manually.) After I mount /dev/sda6, the command df -h gives Filesystem Size Used Avail Use% Mounted on /dev/sda7 244G 221G 12G 96% / udev 3,9G 4,0K 3,9G 1% /dev tmpfs 1,6G 904K 1,6G 1% /run none 5,0M 0 5,0M 0% /run/lock none 3,9G 164K 3,9G 1% /run/shm /dev/sda6 653G 189G 433G 31% /media/8ec2fa69-039b-4c52-ab1b-034d785132a1 (sorry but formatting this into code does not work, for an unknown reason) Thanks to izx's post, I realized /dev/sda6 was not even mounted before. It contains all the documents I used to have when I was running Ubuntu 11.10.

• Will I have internet connection issues next day, if I unplug router at night?

  - by headskracher77

  I did this regularly a few years ago and used to feel like I was 'being punished' by the Interent svc provider for disabling access to my computer, because trying to re-connect the next day became a constant pain. I have the same linksys router, a comcast modem, and hi-speed broadband through their LAN. Question: who or what is at fault for lousy internet connections, slow connections, or no connections: (everybody's tech dept. blames everybody else) The router? 10 year olds, maybe obsolete? The modem? came with the service plan - can connect three devices on a sharedconnection. The ISP: I read they not only even control and completely regulate bandwidth usage, but they also ration it!! (true?) So can I safely 'pull the plug' each night for security or not? thnx

• Translate MSOffice menus from Chinese to English

  - by terence_laoshi

  Hi! I'm stuck in China using a Chinese language MSOffice package (Home and Student). All of the menus and system instructions are in Chinese. I know there's a pack I can buy but that's not an option for this computer and this temporary situation. Is there another way to convert from Chinese to English? OR is there a site that provides some type of tree of all the menu and system information in English. At least that might help. I've done individual searches for a couple of items but that is incredibly time consuming in order to make a simple operational change. Thanks for any help.

• Lenovo G530 laptop screen flicker

  - by Kevin

  I have a Lenovo G530 laptop that has an issue with screen flicker that is getting worse. The computer screen will start going thru a crazy screen flicker then will stop and start again. I have already checked cable connection to lcd on motherboard and reseated connection as someone suggested in another posting I found online that resolved issue. I am starting to think it might be a bad inverter or screen because I have hooked up laptop to external monitor and it is running fine with no flickering happening when the flickering is occurring on laptop. I am attaching a link to a small video I shot of the issue as it is occurring on laptop screen. Does anyone have any further suggestions? Bad inverter or screen? Screen flicker vid

• How can one-handed work in Ubuntu be eased?

  - by N.N.

  My right hand is temporarily immobilized and I would like to do some minor general work on my computer. Mostly web browsing, mailing and file and directory browsing and editing. For this I currently use Firefox, Thunderbird, Nautilus and the GNOME terminal (I have already asked a specific question about Emacs). Are there ways to ease such, or any other general, one-handed work in Ubuntu? I have found http://stackoverflow.com/questions/2391805/how-can-i-remain-productive-with-one-hand-completely-immobilized but that is not exactly what I am asking for. I want to ease whatever little time spent one-handed in Ubuntu and this is also interesting for situations where there is no injury involved, such as when one hand is occupied. I do realize I should avoid unnecessary strain. The main thing that is much slower one-handed is writing. Since I am only temporarily immobilized it seems to make no sense learn a new keyboard layout. I would be surprised if I managed to learn and become more effective with a new keyboard layout (than one-handed QWERTY) before I can use my other hand again. What I have already found: Sticky keys for making it easier to enter keyboard commands. When writing one-handed there are more cases of where it is useful to paste in phrases rather than to reenter them. It is easier to use Super+S rather than CtrlAlt+arrow keys to switch work space.

• Why is my Asus P5PL2-E using 640MB of RAM (out of 4GB) ? [closed]

  - by Tom

  Possible Duplicate: Windows XP and RAM 3.5GB+ I've recently installed 4GB of RAM on my server, which is running Windows XP SP2 32-bit and My Computer showed that only 3.37GB were installed. After digging Google for a bit, I couldn't find anything helpful, but I do remember reading a post in a forum regarding the motherboard using 640MB of RAM. Digging in my own BIOS, I've also found that my motherboard has also reserved that amount for its self. Why does my motherboard reserve this memory and how can I tune it down to say 128MB?

• Is writing recursive functions hard for you?

  - by null

  I'm taking a computer science course now. I feel it is so hard compared to my polytechnic IT course. I can't understand recursive methods well. How do you manage to get your brain to understand it? When the recursive method returns back, my brain can not trace it nicely. Is there a better way to understand recursion? How do you start learning it? Is it normal that feel that it is very hard at then beginning? Look at the example, I'm very surprised how can I write this if it appears in exam. public class Permute { public static void main(String[] args) { new Permute().printPerms(3); } boolean[] used; int max; public void printPerms(int size) { used = new boolean[size]; max = size; for (int i = 0; i < size; i++) { used[i] = false; } perms(size, ""); } public void perms(int remaining, String res) { if (remaining == 0) { System.out.println(res); } else { for (int i = 0; i < max; i++) { if (!(used[i])) { used[i] = true; perms(remaining - 1, res + " " + i); used[i] = false; } } } } }

• What would be a good topic for research on "edge of multiple processors / computers programming" topic?

  - by Kabumbus

  This is a subjective discussion so we can express our dreams and hopes here. A "topic" must be like a task with point to have as end result a software poduct. A "topic" must be mainly about "Software engineering", "Algorithm and data structure concepts" and perhaps "Design patterns". I mean let us try to look what is not already there? What can be developed in fiew month and give a breakthrue / start a new leap / show somethig not realized before in science of f multiple computers programming? What i see is already there: LAN / wire and other infrastractural programms for connecting on device level MPI/ Bit torrent/Jabber protocols / APIs / servers for messaging on top Boost and analogs on evry OS in most languages for multithreading there are lots of CUDA like on computer frameworks for fast calculating on computers GPUs What I personally do not see out there is a crossplatform framework for multiple processes interaction. Meaning one that would allow easy creation of multyple processes running in paralell inside one hoster app on one machine. In level not harder than needed for threads creation (so no seprate server apps - just one lib doing it all) Is there ny such lib and what can you propose for research topic?

• Remote desktop connection drops before login can appear

  - by Keatly

  Hi Everyone, Someone asked this question a few months ago and I have the exact same problem. I have tried all of the suggested solutions in the other posting (in particular reinstalling the video card on the server), but have not had any luck. I have gone through this troubleshooting guide in detail with no results: http://theillustratednetwork.mvps.org/RemoteDesktop/RemoteDesktopSetupandTroubleshooting.html I have a client with Remote Desktop enabled that I can't connect to in our local network. When I enter in the machine ip/port in the connect box and hit Connect, it briefly gives the normal "Connecting..." dialog box. However, after 2 seconds it just drops. No error message, nothing. Just disappears as if nothing was happening. •Windows XP SP3 •Windows firewall is open for 3389TCP •Machine is on a domain •RDP is enabled in My Computer •User is a local admin I have loads of other machines on the same domain with the same GPO that work fine. Any ideas?

• DSL to web connectivity is often lost

  - by broiyan

  I am experiencing a frequent web connectivity problem via a DSL modem. The problem usually shows up as a reload later screen inside of Google Chrome, as illustrated. My DSL service was fine for the first 2 months, but in the most recent month this problem has been occurring. I have this problem several times a day. A few weeks ago, I used to power cycle (off then on) the DSL modem but this usually did not solve the problem. However, in recent days, the power cycle does seem to fix the problem. When the problem occurs, the modem lights do not look unusual. All the lights are green or flashing green. This problem happens regardless of whether I am using ethernet or WiFi for the last few meters between the DSL modem and the computer. What is the likely cause? How can I help the phone company solve this? Their staff are not very effective at troubleshooting this.

• How to connect to my own WiFi using Broadcom STA drivers?

  - by Chris

  I'm trying hard to switch to Linux from Windows because of my engineering project. Unfortunately, everything is against that change! Before I have installed Broadcom STA proprietary drivers, I was seeing on NetworkManager and nm-applet only local radio-internet-access networks. After I installed Broadcom STA, I see my neighbor's wireless network (channel 11, WEP) Neither before nor after the installation is own wireless network available. Computer: Asus Lamborghini VX6 Ubuntu: 12.04 LTS 64-bit Router: ASUS N55U (A1) with newest AsusWRT firmware Network: Channel 5 (tried also 10 and 11, both on 20 and 40MHz bands), WPA2 Personal, 2,4 + 5 GHz (what is not very important, 'cause the wlan card in VX6 is only 2,4GHz). Network works fine on Windows, also through D-Link repeater on the other floor. Unfortunately, same network is invisible to Ubuntu on same machine. I have tried some combinations with other GUIs but it did not work. Are there any better drivers for Ubuntu? I need that network badly, but I'm an Ubuntu newbie, so I don't know how to solve that problem. Please help.

• No sound after upgrading to Ubuntu 11.10 from win7

  - by Tilman

  just as a prefix to my question, i'd like to note that i'm just now entering the world of Linux (unless you count my android, but that's a very different experience...) i have two computers now that run Ubuntu 11.10, the first of which i've had very little problems with, aside from figuring out the basics. the second, from which i'm writing this question, has (up to this point) only had one problem.... no sound. i've read a couple questions similiar and found little help as the component catalog doesn't have my computer listed. (in fact i'm not suprised this is a pos i had my mom grab from her work before they officially closed the doors behind them) had perfect sound before hand, and no sound now. sudo lspci -v brings up 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01) Subsystem: Intel Corporation Device d608 Flags: bus master, fast devsel, latency 0, IRQ 45 Memory at ff980000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [100] Virtual Channel Capabilities: [130] Root Complex Link Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel any help would be greatly appreciated, me and my gf just wanna watch a damn movie lol
