  • No boot or grub file after using ls command

    - by Poke Moke
    I had xubuntu installed, i believe version 12.04 and then tried to dual boot with backbox. It worked from the flash drive but upon installing it onto the hard drive, I could no longer boot backbox. I decided I would just clear my OS and put just backbox on the hard drive and only have a single boot. To do this, I erased my boot file completely which led to my current position. I am put into the grub rescue prompt. I can't do a system restore, I can't boot with anything I might try including puppy linux and a boot rescue, and I've looked up the commands and I've tried to fix this. I can do ls, I find the correct hd but then I'm stuck as I don't have a boot or grub folder. The command is typed as: ls (hd1,msdos1)/ and listed is ./ ../ lost+found/ etc/ media/ bin/ dev/ home/ lib/ mnt/ opt/ proc/ root/ run/ sbin/ selinux/ srv/ sys/ tmp/ usr/ var/ initrd.img vmlinuz cdrom/ apfolder initrd.img.old vmlinuz.old (not sure if it's initrd or init rd.img. as it wraps around the screen there.) I've seen commands regarding boot or grub if they are seen but as listed, they aren't there. Any ideas?

  • Modelling work-flow plus interaction with a database - quick and accessible options

    - by cjmUK
    I'm wanting to model a (proposed) manufacturing line, with specific emphasis on interaction with a traceability database. That is, various process engineers have already mapped the manufacturing process - I'm only interested in the various stations along the line that have to talk to the DB. The intended audience is a mixture of project managers, engineers and IT people - the purpose is to identify: points at which the line interacts with the DB (perhaps going so far as indicating the Store Procs called at each point, perhaps even which parameters are passed.) the communication source (PC/Handheld device/PLC) the communication medium (wireless/fibre/copper) control flow (if leak test fails, unit is diverted to repair station) Basically, the model will be used as a focus different groups on outstanding tasks; for example, I'm interested in the DB and any front-end app needed, process engineers need to be thinking about the workflow and liaising with the PLC suppliers, the other IT guys need to make sure we have the hardware and comms in place. Obviously I could just improvise in Visio, but I was wondering if there was a particular modelling technique that might particularly suit my needs or my audience. I'm thinking of a visual model with supporting documentation (as little as possible, as much as is necessary). Clearly, I don't want something that will take me ages to (effectively) learn, nor one that will alienate non-technical members of the project team. So far I've had brief looks at BPMN, EPC Diagrams, standard Flow Diagrams... and I've forgotten most of what I used to know about UML... And I'm not against picking and mixing... as long as it is quick, clear and effective. Conclusion: In the end, I opted for a quasi-workflow/dataflow diagram. I mapped out the parts of the manufacturing process that interact with the traceability DB, and indicated in a significantly-simplified form, the data flows and DB activity. Alongside which, I have a supporting document which outlines each process, the data being transacted for each process (a 'data dictionary' of sorts) and details of hardware and connectivity required. I can't decide whether is a product of genius or a crime against established software development practices, but I do think that is will hit the mark for this particular audience.

  • USB and CD data cannot be read or mounted in 12.10

    - by aravind4j
    I'm using Ubuntu 12.10. I wrote a data disk using Brasero Disk Burner, but the system cannot read the CD. I tried to write the same data into my HP v220w pen drive but now there is an error in that too. It shows the following: Error mounting /dev/sdb at /media/aravind4j/Aravind4j: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sdb" "/media/aravind4j/Aravind4j"' exited with non-zero exit status 13: $MFTMirr does not match $MFT (record 0). Failed to mount '/dev/sdb': Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details. (udisks-error-quark, 0) I used a NTFS file system for the pen drive as you can recognize from the above statement. I would like to recover the files so please help me recover the files without formatting the drive.

  • Installing Ubuntu Server 12.04 as a software RAID 1 mirror fails to boot

    - by Jeff Atwood
    I'm installing a few new Ubuntu Server 12.04 LTS servers, and they have two 512 GB SSDs. I want them to use software RAID 1 mirroring, so I was following this document religiously step by step: https://help.ubuntu.com/12.04/serverguide/advanced-installation.html To summarize the above official documentation: to set up a software RAID 1 mirror in Ubuntu Server, you choose manual partitioning during the setup, and do this on each drive: "swap" partition of roughly RAM size "physical volume for RAID" partition for remaining drive size After that, you set up the RAID 1 mirror using the RAID partitions on drive A and B, make it ext4 and containing the root filesystem partition. Setup continues from there just fine. One caveat: I was completely unable to select the "physical volume for RAID" as bootable. When I tried to do that in setup, it had no effect: I could press enter on the "make bootable" option all day long and nothing would ever change. However, after install successfully completes, I have a big problem: the system won't boot! I get Reboot and Select proper boot device or Insert Boot Media in selected Boot device and press a key What did I do wrong? Why can't I mark that "physical volume for RAID" partition bootable during Ubuntu Server setup? Is there some way for me to make the physical volumes for RAID bootable after the fact, perhaps from a live CD or something?

  • Dealing with three Windows partitions in dual boot installation

    - by Tim
    For dual-boot installation of Ubuntu after Windows. Quoted from ubuntuguide If a Windows boot partition exists as a second NTFS partition, it should be left alone. If there is a Windows recovery partition also installed, it can also be left alone as long as there are only two NTFS partitions total on the hard drive (i.e. there is no NTFS boot partition as well). If there are a total of 3 NTFS partitions on the hard drive, then the third Windows NTFS partition (the recovery partition) should be removed after creating Recovery CDs from it (see here). In the last case where Windows has three partitions, I was wondering why it says the recovery partition shall be removed? Is it possible to keep the three and create another extended partition with several logical partitions for installing Ubuntu and dual-booting the two OSes? I plan to dual-boot install Ubuntu 10.04 with existing Windows 7. Following is the layout of the current partitions of my hard drive viewed from Windows 7: So must I remove the Lenovo_Recovery (Q:) partition for the same reason you give for the first question? Thanks and regards!

    I created a iso image using aptoncd & burned it to a dvd. now when i tried to restore, the program does not detect the dvd in the drive. It shows "Please insert a disc in the drive." and if we click "ok" it shows "E: Failed to mount the cdrom.". The dvd is in the drive itself.

  • Web Services and code lists

    - by 0x0me
    Our team heavily discuss the issues how to handle code list in a web service definition. The design goal is to describe a provider API to query a system using various values. Some of them are catalogs resp. code lists. A catalog or code list is a set of key value pairs. There are different systems (at least 3) maintaining possibly different code lists. Each system should implement the provider API, whereas each system might have different code list for the same business entity eg. think of colors. One system know [(1,'red'),(2,'green')] and another one knows [(1,'lightgreen'),(2,'darkgreen'),(3,'red')] etc. The access to the different provider API implementations will be encapsulated by a query service, but there is already one candidate which might use at least one provider API directly. The current options to design the API discussed are: use an abstract code list in the interface definition: the web service interface defines a well known set of code list which are expected to be used for querying and returning data. Each API provider implementation has to mapped the request and response values from those abstract codelist to the system specific one. let the query component handle the code list: the encapsulating query service knows the code list set of each provider API implementation and takes care of mapping the input and output to the system specific code lists of the queried system. do not use code lists in the query definition at all: Just query code lists by a plain string and let the provider API implementation figure out the right value. This might lead to a loose of information and possibly many false positives, due to the fact that the input string could not be canonical mapped to a code list value (eg. green - lightgreen or green - darkgreen or both) What are your experiences resp. solutions to such a problem? Could you give any recommendation?

  • How can I refresh/reinstall/clear/set-to-default my bootup process?

    - by Tchalvak
    I'm currently having a problem with my bootup process that is growing progressively worse as time goes on: While booting, it does a few minutes of hard-drive reading. During that, instead of showing a boot splash screen, it shows various dashes and dots, as if the video card isn't recognizing. The splash screen actually has colors similar to the splash screen (purple), it simply is garbled. It then does a few minutes of hard-drive reads, and if I leave it long enough, sometimes it boots into the desktop (and auto-logs-in). Sometimes, unfortunately, it just hangs on that garbled screen and reads from the hard-drive forever. Notably, I've also stopped being able to access grub during bootup (perhaps it is just not displayed correctly by the video, hard to tell). This is a symptom that has grown over the course of various ubuntu upgrades, at least I suspect that the upgrade process is leaving behind cruft. So, is there a safe way for me to "refresh" the boot system so that it is clean, new, fast, and reliable? For example, to test out a cleanly configured boot, make sure that it works (try before I buy), and then apply it to the system to eliminate as much of this problem as possible? Edit: Here is the requested bootchart: http://imgur.com/9jocF

  • Is it possible to get xRandR to see two separate outputs with the nvidia driver?

    - by rumtscho
    I have two monitors, which I have set up with nvidia-settings in Twinview. The result: When I want to do something in xRandR, it does not function. It doesn't report one output per video card head, but a single output mapped to the combined area of both monitors: rumtscho@bradbury:~$ xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 3840 x 1440, current 3840 x 1440, maximum 3840 x 1440 default connected 3840x1440+0+0 0mm x 0mm 3840x1440 50.0* Now I promised somebody to help test a driver. The developer is using an open source driver for Intel video cards, and his driver assumes that there is more than one xRandR output, each mapped to a monitor. So I tried rewriting my xorg.conf to somehow get two outputs to show up, but failed. Googling showed that people faced with the xRandR-nvidia problem either stopped using xRandR and achieved what they needed with nvidia-settings, or changed their driver to nouveau. The first is not going to help in my situation, and I am not willing to give up the proprietary driver, because Compiz won't work without it. So does anybody know a way to get nvidia to actually pass on information on outputs to xRandR?

  • Copy to USB memory stick really slow?

    - by Eloff
    When I copy files to the USB device, it takes much longer than in windows (same usb device, same port) it's faster than USB 1.0 speeds (1MB/s) but much slower than USB 2.0 speeds (12MB/s). To copy 1.8GB takes me over 10 minutes (it should be < 3 min.) I have two identical SanDisk Cruzer 8GB sticks, and I have the same problem with both. I have a super talent 32GB USB SSD in the neighboring port and it works at expected speeds. The problem I seem to see in the GUI is that the progress bar goes to 90% almost instantly, completes to 100% a little slower and then hangs there for 10 minutes. Interrupting the copy at this point seems to result in corruption at the tail end of the file. If I wait for it to complete the copy is successful. Any ideas? dmesg output below: [64059.432309] usb 2-1.2: new high-speed USB device number 5 using ehci_hcd [64059.526419] scsi8 : usb-storage 2-1.2:1.0 [64060.529071] scsi 8:0:0:0: Direct-Access SanDisk Cruzer 1.14 PQ: 0 ANSI: 2 [64060.530834] sd 8:0:0:0: Attached scsi generic sg4 type 0 [64060.531925] sd 8:0:0:0: [sdd] 15633408 512-byte logical blocks: (8.00 GB/7.45 GiB) [64060.533419] sd 8:0:0:0: [sdd] Write Protect is off [64060.533428] sd 8:0:0:0: [sdd] Mode Sense: 03 00 00 00 [64060.534319] sd 8:0:0:0: [sdd] No Caching mode page present [64060.534327] sd 8:0:0:0: [sdd] Assuming drive cache: write through [64060.537988] sd 8:0:0:0: [sdd] No Caching mode page present [64060.537995] sd 8:0:0:0: [sdd] Assuming drive cache: write through [64060.541290] sdd: sdd1 [64060.544617] sd 8:0:0:0: [sdd] No Caching mode page present [64060.544619] sd 8:0:0:0: [sdd] Assuming drive cache: write through [64060.544621] sd 8:0:0:0: [sdd] Attached SCSI removable disk

  • X won't start, root filesystem mounted read only

    - by TK Kocheran
    I just experienced a very strange and puzzling problem on my machine that I can't seem to get sorted out. I was running Windows on a second partition, and everything was working great. I then went to restart into Linux, and noticed that X wouldn't start. Everything was displayed in super-low resolution, so I tried reinstalling my NVIDIA driver. I started seeing all of these I/O error problems, so I figured that my SSD was bad. After a bit more playing around, I ran fsck on the drive when mounted from a startup disk as well as badsectors and everything looked great. The SMART drive tests all passed and again, everything was looking good, so I rebooted again and still, no joy. I started then getting some weird USB errors, so I followed someone's advice and unplugged my computer's power supply, then started back up again and my graphics looked a lot better in the BIOS and in the boot logo, but X still wouldn't start. I then found out that my main boot drive was being mounted read-only for some reason. What's going wrong? I've done some pretty extensive tests on the SSD from a startup disk such as writing massive files, reading big files, running filesystem checks on the entire disk, and everything is looking great, until I try to boot. Whenever I try installing the drivers with apt-get, I get a ton of ata error messages looking like this: How can I diagnose what's going wrong and fix it so I can get back to work?

  • Trouble dual booting Ubuntu 14.04 & Windows 8

    - by AkBKukU
    My motherboard (MSI G45-Z87) has efi, I still can't figure out how to make stuff work with it. I had Ubuntu working with Windows 8 before 14.04 came out and I did a clean install of Ubuntu when it did to upgrade. Since then I hadn't been able to boot Windows but I don't use it anyway so it didn't effect me. I tried getting it working today so I could use some adobe software. The last time I had tried to do something with the boot it was giving me warnings that my boot files were to far in the drive. So I followed this guide to use gparted and boot-repair to add a boot partition. I was able to reboot Ubuntu after that. I then proceeded to install Windows 8.1 to a different drive. Now the computer will only boot straight into Windows and if I manually select Ubuntu, but not the drive Ubuntu is on, to boot it stops on a black screen during boot after showing the Ubuntu logo. I've run boot-repair in several different ways but have had no luck. Here is the boot summary info from the recommended settings for it. I could really use some help.

  • Do you have to recreate workspaces after upgrading a TFS 2008 server to TFS 2010?

    - by Clara Oscura
    I am just reposting this thread from a MSDN forum since it seems to be unavailable. It was very useful when I was having trouble with my folder mappings after migrating to TFS 2010. Question: I opened VS2008 and connected it to the upgraded 2010 TFS server.  Upon clicking any of our Team Projects in source control explorer I get "Team Foundation Error - The workspace MYWORKSPACE;DOMAIN\MYUsername already exists on computer MYPCNAME." Answer: The same local paths on your machine are mapped to 2 different workspaces, one on the preupgrade server and one on the postupgrade server.  It's not safe to have multiple workspaces on different servers mapped to the same local paths b/c you could pend some changes while connected to one server, and the other server would have no idea what you did.  You should either delete your conflicting workspaces from one of the servers (if you don't need them on both), or test the new TFS instance from a new workspace (on different machine). If you want to test an existing production workspace on both servers, then yes, you will have to mess around with the workspace cache. You don’t have to delete the entire cache, you just need to run "tf workspaces /remove:* /server:<serverurl>" to clear the cached workspaces from a server (the command won't delete the workspaces), and possibly "tf workspaces /server:<server>" to refresh the workspace cache for a given server.  You will also have to do back up and restore the workspace before switching servers or your local files could be inconsistent. From the “Microsoft Visual Studio Team Foundation Server 2010 Beta 1” forum (not available anymore?) Technorati Tags: TFS 2010,TFS Workspaces,Team System,Team Foundation Server 2010

  • Live CD installer gets stuck with a grayed out forward button.

    - by TRiG
    I have a CD with Ubuntu 10.10 and a laptop with Ubuntu 8.10. The laptop had all sorts of crud on it, and anything I wanted to keep was backed up on an external drive, so I was happy to do a wipe and reinstall instead of an update. So after a bit of faffing about trying to work out how to get the thing to boot from the CD drive, I did that. So the screen comes up with the choice: the options are Try Ubuntu and Install Ubuntu. I choose to install and to overwrite my current installation. So far so good. I then get a progress bar labelled something like copying files (I forget the exact wording) and further options to fill in for my location, keyboard locale, username and password. On each of these screens there are forward and back buttons. On the last screen (password), the forward button is greyed out. Well, I think to myself, no doubt it will become active when that copying files progress bar completes. The progress bar never completes. It hangs. And the label changes from copying files to the chirpy ready when you are. The forward button remains greyed out. The back button is as unhelpful as you'd expect it to be. And there's nothing else to click. We have reached an impasse. I tried restarting the laptop, to test whether it actually was properly installed. It wasn't. I tried to run Ubuntu live from the CD, to test whether the disk was damaged. That wouldn't work either, but I suspect it's just because the laptop is old and has a slow disk drive. I'm typing this question on another computer using the Ubuntu live CD and it's working fine. So there's nothing wrong with the CD.

  • Clustering Strings on the basis of Common Substrings

    - by pk188
    I have around 10000+ strings and have to identify and group all the strings which looks similar(I base the similarity on the number of common words between any two give strings). The more number of common words, more similar the strings would be. For instance: How to make another layer from an existing layer Unable to edit data on the network drive Existing layers in the desktop Assistance with network drive In this case, the strings 1 and 3 are similar with common words Existing, Layer and 2 and 4 are similar with common words Network Drive(eliminating stop word) The steps I'm following are: Iterate through the data set Do a row by row comparison Find the common words between the strings Form a cluster where number of common words is greater than or equal to 2(eliminating stop words) If number of common words<2, put the string in a new cluster. Assign the rows either to the existing clusters or form a new one depending upon the common words Continue until all the strings are processed I am implementing the project in C#, and have got till step 3. However, I'm not sure how to proceed with the clustering. I have researched a lot about string clustering but could not find any solution that fits my problem. Your inputs would be highly appreciated.

  • I cannot boot Ubuntu from WUBI install with windows 7, get an error message every time

  • Ubuntu install can't find hard drives

    - by Casey Hungler
    I recently got a Dell Inspiron Special Edition 7720 computer. I am trying to install Ubuntu along side Windows. When I use the WUBI installer, the installation of Ubuntu works as long as I do not boot into Windows; if I boot into Windows, when I go back into Ubuntu, I am given a variety of error messages which claim to have corrupt or missing kernel/root directory, etc. I have been working with this problem for about a week, and have reinstalled Ubuntu MANY times. So far, I have eliminated all of the following problems: Corrupt WUBI installation (Downloaded multiple times, used on other systems), I have tried using a CD and a flash drive, both of which work on other computers. I know that no program within Ubuntu is creating the problem. I know that others have successfully installed Ubuntu on a computer with my operating system (Windows 7 SP1). This is a much shortened version of the original question, which has been up for about 5 days, and included a more detailed description of the problem, but left everyone clueless as to the source of this problem. When I spoke with the Dell service technician who came over today to replace my keyboard, he suggested that the driver for my HDD was so new that it was not compatible with the current version of Ubuntu. His reasoning is as follows: 1) During an install from a flash drive or CD, where I am supposed to get the option to wipe my system or create a dual boot, I get a window that asks me to select a hard drive partition, but none are listed. 2) This model of computer was made public in June of this year, while Ubuntu was released in April Adopting this theory, it would seem to me that the WUBI install fails after booting into Windows because Ubuntu can no longer find the files that it needs to load. Does this theory seem at all plausible to anyone? I just want to install Ubuntu and have it stay on my computer. I don't care how I put it there, I just need it to work, so I would TRULY appreciate any advice or suggestions anyone could give. Thanks so much for your time and support!!!

  • Dell Powerdge840 2.4GHz 64 bit quad core

    - by newb64bit
    I am having an issue, where I have changed the boot order to cdrom and turned off hd boot all together and still my system is unable to detect ubuntu and claims, no boot device found. Some additional information: When this same cd is inserted and dell is booted into win 2003 server (which is what is installed on this machine), it detects the cd drive but not the cd at all (keeps asking me to insert disc) I have also created a bootable flash drive using LinuxLive USB creator and when this is selected in boot order again am told no boot device detected. I was speaking to dell and they suggested perhaps there are no drivers on the actual ubuntu installation for the hardware on this Dell and hence the failure of this dell to detect the ubuntu cd. Now, I don't know too much about computers, but this last bit confused me a bit. If the system detects the hardware (when it is booting it sees the cd rom and in bios it sees when the flash drive is connected), then shouldn't it be able to read what is on those drives? However, if there is some firmware or software install that needs to happen, could someone please tell me where to find the correct drivers for ubuntu and dell poweredge to work together? Shall I be installing the desktop version or the server edition, also, 32 bit or 63 bit? Thank you in advance.

  • Is there supposed to be a Windows Network folder in the file manager?

    - by Cindy
    I pulled my hard drive out of my computer and started with a bootable usb version of Ubuntu, which I am using that at this point. At first boot, I see that there is a Windows folder when browsing network. Since there is no operating system present, besides the usb that I boot from, should there be a Windows network folder? Original question First of all I just want to say, I wish I had tried Ubuntu a couple years ago when I first heard about it, but I was like a lot of the population and went with the "easy way" and stuck with Windows because I didn't want to take the time to learn something new. Well, about 3 months ago I realized someone had hacked into my computer, and then found they had hacked my facebook account so I decided I had better do a complete credit check. I found student loans (totalling about 30,000 so far) had recently showed up on my credit report. I think it's going to be a long, long road to recovery now but I'm hoping Ubuntu will be a start and definitely an eye opener. My relationship with Windows is over. I had 3 antivirus programs running, none were protecting me like I thought they were. Turned out a free program that I downloaded was the only one that could detect and clean the virus, but by then it was too late. Anyhow, my question is, I pulled my hard drive out of my computer and started with a bootable usb version of Ubuntu, which I am using that at this point. At first boot, I see that there is a Windows folder when browsing network. Since there is no operating system present, besides the usb that I boot from, should there be a Windows network folder? I am using a local ISP (and won't be much longer because I am very paranoid at this point) and I want to make sure all is ok before I put my new hard drive in and install Ubuntu. Any help would be appreciated. Also, I want to thank Ubuntu and the community for giving people an alternative.

  • Installation on SSD with Windows preinstalled

    - by ebbot
    I bought a laptop with this fancy SSD drive, fancy new UEFI aso. I figured at first Windows out Ubuntu in but after doing 3 DoA on 3 laptops in one day I realized that maybe keeping Windows could come in handy. So dual boot it is. And this is what I've got: Disk 1 - 500 Gb HD 300 Mb Windoze only says "Healthy" don't know what it's for. 600 Mb "Healthy (EFI partition)" 186.30 Gb NTFS "OS (C:)" "Healthy (Boot, Page File, Crash Dump, Primary Partition)" 258.45 Gb NTFS "Data (D:)" "Healthy" 20.00 Gb "Healthy (Recovery Partition)" Disk 2 - 24 Gb SSD 4.00 Gb "Healthy (OEM Partition)" 18.36 Gb "Healthy (Primary Partition)" So I'm not sure what the first partition on each drive does (the 300 Gb on the HD and the OEM Partition on the SSD. Nor do I know what Data (D:). I think the 2nd partition on the SSD is for some speedup of Windoze. I'm debating if I should shrink the OS (C:) drive to around 120 GB or so. Clear the Data (D:) and also use the whole SSD for Ubuntu. That would leave me 24 Gb for e.g. / on the SSD and some 320 Gb on the HD for /home and swap. Is this a reasonable setup? Do I need to configure fstab for the SSD differently to a HD?

  • 12.04 doesn't boot anymore after a power failure

    - by Felix
    I'm a Windows user and I have no experience with Linux and Ubuntu. I installed Ubuntu 12.04 on my netbook (Asus 1215B) and everything works fine. Yesterday I ran the "update application" and updated over 120 "things" (I have no idea what exactly). After that I was asked to reboot, and I did. Ubuntu starts again and at the load screen with these 5 dots that normally begin to change color, it freezes. After 20 minutes I took out the battery to try another reboot (yes, not the the best idea), and now nothing happens. I boot from the HDD and I get an Error BOOTMGR is missing. I have important data on the hard drive. Is there an option to get this fixed? Or if not, to at least get the data from the hard drive? Ubuntu 12.04 64-bit Edit: it is ONLY Ubuntu on this Netbook, which uses the whole 500gb HDD as 1 Partition. Filesystem is NTFS. Whole Hardware seems okay. The USB drive which i used to instl the Os was formated in fat32

  • How to join a Windows Domain an Map NEtwork Drives on Ubuntu Partition

    - by AgainstClint
    I just installed the current build for Ubuntu on a partition for my work computer. I am a novice when it comes to Linux/Ubuntu, which is why I installed it along side windows. I want to learn how to operate and use Ubuntu much more than I do now, so I figured installing it and trying to do day to day functions here would be a "Thrown into the pool with sharks" way to do it, and I like that way. I did however have a few questions: We are on a Domain in Windows, is there any way to join that domain using the Ubuntu partition? We Also have 16 mapped network drives. I don't actually need ALL of them mapped for Ubuntu, but is there a way to Map at least one of them to see/use here in Ubuntu. Outlook Corporate email, how can I sign in/use it while...well, you get the idea. As I said earlier, I am VERY new to Ubuntu, i've only played around with it a bit at home and never at the office. If you could simplify it down for me a bit, that would be great.

  • What's wrong with this Open GL ES 2.0. Shader?

    - by Project Dumbo Dev
    I just can't understand this. The code works perfectly on the emulator(Which is supposed to give more problems than phones…), but when I try it on a LG-E610 it doesn't compile the vertex shader. This is my log error(Which contains the shader code as well): EDITED Shader: uniform mat4 u_Matrix; uniform int u_XSpritePos; uniform int u_YSpritePos; uniform float u_XDisplacement; uniform float u_YDisplacement; attribute vec4 a_Position; attribute vec2 a_TextureCoordinates; varying vec2 v_TextureCoordinates; void main(){ v_TextureCoordinates.x= (a_TextureCoordinates.x + u_XSpritePos) * u_XDisplacement; v_TextureCoordinates.y= (a_TextureCoordinates.y + u_YSpritePos) * u_YDisplacement; gl_Position = u_Matrix * a_Position; } Log reports this before loading/compiling shader: 11-05 18:46:25.579: D/memalloc(1649): /dev/pmem: Mapped buffer base:0x51984000 size:5570560 offset:4956160 fd:46 11-05 18:46:25.629: D/memalloc(1649): /dev/pmem: Mapped buffer base:0x5218d000 size:5836800 offset:5570560 fd:49 Maybe it has something to do with that men alloc? The phone is also giving a constant error while plugged: ERROR FBIOGET_ESDCHECKLOOP fail, from msm7627a.gralloc Edited: "InfoLog:" refers to glGetShaderInfoLog, and it's returning nothing. Since I removed the log in a previous edit I will just say i'm looking for feedback on compiling shaders. Solution + More questions: Ok, the problem seems to be that either ints are not working(generally speaking) or that you can't mix floats with ints. That brings to me the question, why on earth glGetShaderInfoLog is returning nothing? Shouldn't it tell me something is wrong on those lines? It surely does when I misspell something. I solved by turning everything into floats, but If someone can add some light into this, It would be appreciated. Thanks.

  • how to use a batch file to delete a line of text in a bunch of text files? [on hold]

    - by wbt
    I have a bunch of txt files in my D drive which are placed randomly in different locations.Some files also contain symbols.I want a batch file so that i can delete their specific lines completely at the same time without doing it one by one for each file and please refer to a code which does not create a new text file at some other location with the changes being incorporated i.e I do not want the input.txt and output.txt thing.I just need the original files to be replaced with the changes as soon as i click the batch file. e.g D:\abc\1.txt D:\xyz\2.txt etc I want both of their 3rd lines erased completely with a single click and the new file must be saved with the same name in the same location i.e the new changed text files must replace the old text files with their respective lines removed.Maybe some sort of *.txt thing i.e i should be able to change all the files with the .txt extensions in a drive via a single batch file perhaps in another drive,not placing my batch file into each and every folder separately and then running them.Alternatively a vbs file is also welcomed. SORRY FOR THE LONG AND THOROUGH MESSAGE BUT I'M WONDERING ALL OVER THE INTERNET FOR THE LAST TWO DAYS JUST FOR THIS ONE BATCH FILE.ALL THE INFORMATION I GET IS A SORT OF JARGON FOR ME AS I AM NOT A GEEK WITH THE SCRIPTING.PLEASE DESCRIBE THE CODE TOO.YOUR HELP IS MUCH APPRECIATED
