• Still can't mount windows 8 drive after restart

  - by Ishai Bloch

  After following the instructions in other posts, I am still getting the same error when I try to mount my Windows 8 drive in Ubuntu 14.04 on a dual boot system. I have disabled fast start after shutdown, hybrid hibernation, and the preinstalled Asus Instant On service. I have tried restarting Windows rather than shutting down. In all cases I get the same error message, namely: Error mounting /dev/sda4 at /media/jesse/OS: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda4" "/media/jesse/OS"' exited with non-zero exit status 14: Windows is hibernated, refused to mount. Failed to mount '/dev/sda4': Operation not permitted The NTFS partition is in an unsafe state. Please resume and shutdown Windows fully (no hibernation or fast restarting), or mount the volume read-only with the 'ro' mount option. I did not have the same issue before upgrading from Ubuntu 12 to 14. For what it's worth my computer is supposedly a "hybrid" with an SSD drive installed, although I can't see that the SSD drive is being used at all with my present settings. Any thoughts?

• Excel - add target line to stacked bar chart

  - by Chris W

  I've got a stacked bar chart. I'm displaying a set of floating bars to represent hi/low ranges for some metrics, by using a transparent fill on the bottom section of the bar I achieve the desired look. What I now need to do is add a horizontal line across the chart to indicate how a particular users score relates to all of these hi/low ranges therefore the placement of this line needs to be dynamic based on a value in a cell. Is there anyway to do this as I can't find an easy option. If this was a simple bar chart I could add the target scores as new series and use the line chart type but I don't seem able to overlay a second series on the stacked bar chart. I'm using 2003 at the moment but run this in 2007 if that helps.

• Windows 8 sleep, blank screen on resume

  - by Waqar Hameed

  I use a SONY VAIO laptop VPCS116FA that came pre-installed with Windows 7. I have upgraded to Windows 8. The experience has been good so far but I am facing a frustrating problem. Whenever, I put my computer to sleep, it won't wake up and I have to restart it. Note that this does not affect hibernation which works perfectly fine. However, it is not a perfect alternative to sleep option. I have tried this method to resolve the problem but in vain: http://www.thulasidas.com/2009-03/blank-screen-after-hibernatesleep.htm I really am in need for a solution to this problem. Please suggest whatever you think can resolve this.

• How would I batch rename a lot of files using command-line?

  - by Whisperity

  I have a problem which I am unable to solve: I need to rename a great dump of files using patterns. I tried using this, but I always get an error. I have a folder, inside with a lot of files. Running ls -1 | wc -l, it returns that I have like 160000 files inside. The problem is, that I wish to move these files to a Windows system, but most of them have characters like : and ? in them, which makes the file unaccessible on said Windows-based systems. (As a "do not solve but deal with" method, I tried booting up a LiveCD on the Windows system and moving the files using the live OS. Under that Ubuntu, the files were readable and writable on the mounted NTFS partition, but when I booted back on Windows, it showed that the file is there but Windows was unable to access it in any fashion: rename, delete or open.) I tried running rename 's/\:/_' * inside the folder, but I got Argument list too long error. Some search revealed that it happens because I have so many files, and then I arrived here. The problem is that I don't know how to alter the command to suit my needs, as I always end up having various errors like Trying find -name '*:*' | xargs rename : _, it gives xargs: unmatched single quote; by default quotes are special to xargs unless you use the -0 option [\n] syntax error at (eval 1) line 1, near ":" [\n] xargs: rename: exited with status 255; aborting Adding the -0 after xargs turns the error message to xargs: argument line too long These files are archive files generated by various PHP scripts. The best solution would be having a chance to rename them before they are moved to Windows, but if there is no way to do it, we might have a way to rename the files while they are moved to Windows. I use samba and proftpd to move the files. Unfortunately, graphical software are out of the question as the server containing the files is what it is, a server, with only command-line interface.

• SVN command that returns wether a user has a valid login for a repository?

  - by Zárate

  Hi there, I'm trying to find out an SVN command that would return some kind of true / false value depending on wether the user running it has access to a given repository. I'm building a tool for automated deployment and part of the process is checking out the code from the SVN repository. I'd like to find out if the user running the tool has a valid login already. If there's no valid login, just show a message and exit the tool (handling the SVN login internally is not an option at the moment). Plan B would be parsing the file in svn.simple looking for the repo URL, but thought about asking first. Thanks, Juan

• BizTalk Schema Validation

  - by Christopher House

  Perhaps this one should be filed under:  Obvious Yesterday I created a new schema that is going to be used for a WCF receive.  The schema has a bunch of restrictions in it, with the intention that we'd validate incoming messages against the schema.  I'd never done message validation with BizTalk but I knew the XmlDisassembler component had an option for validating, so I figured it would be a piece of cake.  Sadly, that was not to be the case.  I deployed my artifacts and configured my receive location's XmlDisassembler with what I thought to be the correct document spec name.  I entered My.Project.Name.SchemaTypeName for the document spec and started running unit tests.  All of them failed with the following error logged in the event log: "WcfReceivePort_BizTalkWcfService/PurchaseOrderService" URI: "/BizTalkWcfService/PurchaseOrderService.svc" Reason: No Disassemble stage components can recognize the data. I went to the receive port and turned on tracking, submitted another message, then went to the admin console and saved the message.  It looked correct, but just to be sure, I manually validated it against the schema in my project.  As expected, it validated correctly. After a bit of thinking on this, I realized that I probably needed to fully qualify my document spec name, meaning, include the assembly name, as well as the type name.  So, I went back to the receive location and changed the document spec to: My.Project.Name.SchemaTypeName, My.Project.Name,Version=1.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxx I re-ran my unit tests and everything was working as expected.  So, note to self:  remember to include the assembly name when setting the document spec.  If you need an easy way to determine your schema name and assembly name, find your schema in the admin console and go to it's properties.  On the property screen, look at the Name and Assembly properties.  Your document spec will be "SchemaName, AssemblyName"

• scp vs netatalk, samba, and/or vsftpd with External USB drive

  - by KitsuneYMG

  I set up a ubuntu server machine to share an ext2 formatted external usb drive. When attempting to copy a single 275MB files from said device through netatalk, I get estimated download rates at around 45 min. With samba and ftp (using vsftpd) I get 1+ hours! Using scp to copy the file results in complete download within 5 minutes. Another option, ssh+cp from external device to ~ and then using netatalk to grab it from there results in a total time of arounf 7 minutes. Does anyone have a clue what is misconfigured? Assuming that nothing is, is there any fs/pseudo-fs that would use the internal hdd as an intermediate location/onion-layer for the external hdd (for reads only)? Details: AppleVolumes.default: /mnt/ext USB allow:username cnidscheme:cdb options:usedots,upriv

• How to get started in coding for JBoss

  - by Mister IT Guru

  I have an idea on how to revamp our internal application, after having accessed the needs of the users, addressing thier current issues, and the like. But I am not a coder. My last application I wrote was in college, in C, (java wasn't invented-ish!) and it was a booking system, with the option to add on other modules, blah blah. I got an A, but I became a system administrator instead, more intrested in designing and maintainend networks and infrastructure, but with the advent of virtualisation, and linux management tools such as puppet I can now manage infrastructure in my sleep! Now I want to write code - to put on my infastructure, and I want to build .... a booking system! This is just to get experience, but I am at a loss as to where to start. Setting up the environment, will take me about a day. Writing the spec, even how I want it to work, I already know, but as for actually coding in a decent manner, I can only guess. If anyone can recommend a book, website, blog, twitter person to follow, or just advice on how to build a kick butt basic jboss app, then please, "I AM READY TO LEARN" :)

• VMWARE V2V migration without shared storage

  - by TheCleaner

  I would like to do the following: Take Physical box running w2k8r2 and Sql2008R2 and do a P2V on it to a 4.1 Enterprise licensed cluster. --no worries here, I can do that part-- Take the existing physical box that is freed up and install vmware hypervisor 5.0 on it. --again I can do this part-- Do a v2v migration of the VM created in step #1 above from the Enterprise 4.1 Cluster to the standalone host. They are NOT using shared storage. Step #3 is where I'm confused as to what my best option is. I found an article online talking about using Veeam FastSCP and just shutting down the vm on the cluster, removing it from inventory, copying the files over to the new host and then adding it to inventory. Is that the best way to accomplish this?

• Change default text editor for crontab to vim

  - by Max Williams

  I'm using ubuntu 9.10 and the default text editor is nano, which i hate. (doesn't everyone?) Normally it's not a problem as i just vi or gedit everything but crontab -e is opening with nano. I tried changing it to vim using sudo update-alternatives --config editor and selecting option 3 ("/usr/bin/vim.basic"). This has changed it for sudo and non-sudo alike. But crontab -e still opens nano. Any ideas? max

• Supporting and testing multiple versions of a software library in a Maven project

  - by Duncan Jones

  My company has several versions of its software in use by our customers at any one time. My job is to write bespoke Java software for the customers based on the version of software they happen to be running. I've created a Java library that performs many of the tasks I regularly require in a normal project. This is a Maven project that I deploy to our local Artifactory and pull down into other Maven projects when required. I can't decide the best way to support the range of software versions used by our customers. Typically, we have about three versions in use at any one time. They are normally backwards compatible with one another, but that cannot be guaranteed. I have considered the following options for managing this issue: Separate editions for each library version I make a separate release of my library for each version of my company software. Using some Maven cunningness I could automatically produce a tested version linked to each of the then-current company software versions. This is feasible, but not without its technical challenges. The advantage is that this would be fairly automatic and my unit tests have definitely executed against the correct software version. However, I would have to keep updating the versions supported and may end up maintaining a large collection of libraries. One supported version, but others tested I support the oldest software version and make a release against that. I then perform tests with the newer software versions to ensure it still works. I could try and make this testing automatic by having some non-deployed Maven projects that import the software library, the associated test JAR and override the company software version used. If those projects build, then the library is compatible. I could ensure these meta-projects are included in our CI server builds. I welcome comments on which approach is better or a suggestion for a different approach entirely. I'm leaning towards the second option.

• Problems syncing photos and strange effects of uploaded files from other devices

  - by Daniel

  I have a Galaxy Spica (GT-i5700) Android v2.1, rooted with Leshak dev 7 #123. But never mind the root info, the problem would be the same unrooted. The photos from this phone is stored in "sdcard/images", nevertheless the phone also creates a "sdcard/DCIM" but only stores some thumbnails there. Problem nr 1: U1 only reads the DCIM-folder for automatic photo-upload. So photos stored in this phone is not uploaded. If I move photos to "DCIM" folder, U1 recognises the photos and start uploading them. Possible solution: Could there be an option in the settings, to set preferred photo folder? Problem nr 2: Out of 74 pictures, 12 did not get uploaded. Pressing "Retry failed transfers" in Settings does nothing. Pressing the files where status is "Upload failed, tap to retry" only changes the status to "Uploading..." but nothing gets uploaded. If I upload another file to U1, it is uploaded directly without any problem. It has nothing to do with file size, 1,1 MB files has been uploaded fine whilst some failed are 0,8 MB. Problem nr 3: The photos from DCIM are in my case uploaded to a folder called "Pictures - GT-I5700" in U1. If I log in to the homepage and from there upload another photo in "Pictures - GT-I5700", it shows up in U1 on my phone fine. But when I tap it, U1 downloads the photo to "sdcard/U1/Pictures - GT-I5700". If it sync photos from "sdcard/DCIM" to a specific folder, why not also download files to the same folder from which it is synced? After a while of usage, syncing and uploading files from different clients it would be a mishmash of folders and places files are stored and considering that I see no use of U1 at all. Another question: If my SD card in some way breaks down/some folders cannot be read/card temporarly changed and U1 is running, does U1 consider that as files deleted and also delete from the cloud?

• How to customize Windows 7 HAL library during installation (BSOD STOP: 0x000000A5)?

  - by koldovsky

  While trying to install Windows 7 x86 Ultimate on Samsung M40 laptop (Pentium M 1.7 Dothan, 2 GB RAM/ 100 GB HDD) i receive BSOD STOP: 0x000000A5: The bios in this system is not fully ACPI compliant. Please contact your system vendor for an updated bios. The bios on the system is updated to latest version. If ACPI is the real source of the issue it means that I possibly could use another HAL library. In Windows XP it is possible to install system with generic HAL library pressing F7 when installer asks to supply drivers, but on Windows 7 I can't find such option. Ironically, Vista installs and works nice, even if they said that Windows 7 is less demanding for hardware. Windows 7 Advisor also tells nothing suspicious. Can anybody tell me how to customize Windows 7 installer to use generic HAL library (if it is possible, of course) or point me to another solution?

• How do I run a batch file async using PSExec?

  - by Paul Mrozowski

  I have a batch file I run that, among other things, reset's the NICs in the machine. I have some watchdog software running on another machine that monitors the first one. I'd like to run this batch file using PSExec when it detects certain types of failures. The problem I'm having is that since the batch file reset's the NIC's it kills the connection PSExec has (I'm OK with that). The real issue is that when PSExec dies the batch file stops running (leaving the NIC's disabled). I've tried using the -i option with PSExec with no luck. Any ideas about basically just fire off the batch file and NOT have it stop when PSExec is disconnected?

• How to disable a touchpad on an Acer Travelmate 6492?

  - by un pobrecito hablador

  I think it's broken because it starts working in the same way when i install their drivers in windows. It's an acer travelmate 6492. I want to disable it because i think that is broken, however i'm going to write what happens and if someone knows what could be wrong if it's not physically broken, can tell me how to solve it. Well, the main problem is that is scrolling all down every time so i can't do almost anything. I've tried to remove xserver-xorg-input-synaptics but it got worse and it was every time pressing enter or something like that so it was very annoying. Then when i could repair it, i tried with gpointing-device-settings and gsynaptics, but it continued doing the same even with i disabled it from there. The only thing that seems to have a positive effect is to use x(whatever) option instead of gnome when login in and disabling it with xinput. However, it only lasted some minutes before it started working and i had to disable it again. Any idea about how can i disable or fix it? Thanks in advance.

• 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?

• Joining a company to get experience vs. going alone [closed]

  - by daniels

  My goal is to build a successful web startup, say the next Digg or Twitter, and I am in doubt regarding what is the best route to follow as a programmer. I see basically two options: Get an internship/job with an established online company, so that I could get a mentor and learn from more experienced programmers, learn their processes, methodology and so on. I could do this for 1-2 years, and then quit to start working on my own stuff. Start working on my own projects right away, starting with small ones and moving up gradually. This would give me more control on the things I would be working with, but I would lack contact with more experienced people, so I would need to figure basic things on my own. Doing both is not an option in my opinion, cause I would need to put a lot of effort/time into each if I was to learn/improve as a programmer. So is one route definitely better than the other? Is there a third one I am not considering? Background: I already work by myself developing content-based websites and doing SEO, and I am decent at it so money is not a problem. Last year I started learning to program, first by myself and now I enrolled in a CS degree on a good university.

• How can I make a specific image stop loading in Firefox?

  - by Gibby

  I don't want to prevent all images from loading or stop loading everything, I just want to stop loading an individual image after I've seen that it's probably not something I care about so I can use that bandwidth for something else. My internet is very slow, but I still like browsing sites like tumblr, imgur, etc. that have lots of images. It seems like GIFs are getting more and more common and they can be several megabytes each... my internet just can't handle it. When I right-click a broken/unloaded image in Firefox, there's an option to reload the image. I essentially want the counterpart to that: to right-click a still-loading image and stop the download. Is this possible? Greasemonkey script, extension, I'll take any method.

• IE8 HTTPs Download Issue

  - by Jon Egerton

  I have a problem with a system I develop related to IE8 downloading over SSL (ie on sites using https://...) and is described on this MS kb article: http://support.microsoft.com/kb/323308 We use the HTTPCacheability.NoCache option as the data being downloaded is sensitive, and is downloaded from a secured site. I don't want that data to be cached on any of the proxies etc that the response passes through back to the client. The article describing the issue details a fix to the client side registry changing a BypassSSLNoCacheCheck setting. I don't want to loosen the system security just for IE8, as the system works fine on anything more upto date. Getting all the clients to apply the hotfix is difficult at best, and impossible at worst. We need to support IE8 in the system, at least for now. So: 1: Does the detailed hotfix have any implications for the security at the browser end in IE8 - does it mean the file will be cached? (in a place other than where the user saves the file). 2: Is there some way I can get these files downloadable with a change at the server end that doesn't break the security side of things?

• Trancoding a video with vlc and the MPEG-4 codec with a video bit rate

  - by Nicolas

  When I try to trancode a video with vlc using the MPEG-4 codec and a video bit rate, I get the following error : Either both buffer size and max rate or neither must be specified Here is the command line I used : vlc -vvv myvideo.m2ts --sout-ffmpeg-strict=-2 --sout '#transcode{vcodec=mp4v,vb=2000,acodec=mp4a,ab=96}:standard{access=file,mux=mp4,dst=/path/file.mp4}' It seems that I can't specify a video bit rate with the MPEG-4 codec. (If I remove the vb option, it works). So how can I specify a video bit rate with the MPEG-4 codec ?

• How do I finish installing Sun JDK after cancelling out of the legal term screen?

  - by Ravi

  I am a newcomer to linux and have had lots of problems in installing java on my newly installed Ubuntu 11.10. I use a statistical programming environment called R and many of the packages there require java (the sun variety, I am told). I tried the following : sudo add-apt-repository ppa:ferramroberto/java sudo apt-get update sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts (after this, I wanted to continue with (but never got that far) : sudo apt-get install sun-java6-jdk After this, a window appeared with the heading, "Configuring jre", or something like that. Below was a long list of legal text about accepting Sun's terms. I did not know how to close this window (no obvious option like pressing return worked). After a long time, when nothing seemed to happen, I finally closed the window. After that, I could not open synaptic. I got the error message : dpkg was interrupted. You must manually run 'sudo dpkg --configure -a' I did this. But it does not help. I have java as a "broken" program. When I try to remove the program from synaptic, I get a message that I must reinstall it again.I do not know what I should do. I want to install jdk6. And also remove the open jdk which is still persistently present in my system. I tried the clean and purge command shown below. Next, I tried to remove the sun-java6-jre from synaptic. I get the following message :E: sun-java6-jre: Package is in a very bad inconsistent state - you should reinstall it before attempting a removal. When I tried to follow the procedure suggested in the related question (from the link suggested below), I get the following message on trying to install again :Could not mark all packages for installation or upgrade.The following packages have unresolvable dependancies. Make sure that all required repositories are added and enabled in the preferences. sun-java6-bin : Depends: sun-java6-jre but it is not going to be installed

• Is it possible to spoof the From: field in Outlook?

  - by tsv

  I am wondering if it is possible to change the From: field (not just the reply-to) in Outlook (specifically in the 2010 beta, but also interested in other versions). I am just moving over from Linux and am used to being able to do this quite simply in some clients. At first I thought it was the option of "Other E-Mail address" on the From drop down menu in a compose window, but that seems to do... nothing! I want to be able to do this so I can have email look like it comes from a domain I own but do not wish to run an SMTP server on.

• More than one way to skin an Audit

  - by BuckWoody

  I get asked quite a bit about auditing in SQL Server. By "audit", people mean everything from tracking logins to finding out exactly who ran a particular SELECT statement. In the really early versions of SQL Server, we didn't have a great story for very granular audits, so lots of workarounds were suggested. As time progressed, more and more audit capabilities were added to the product, and in typical database platform fashion, as we added a feature we didn't often take the others away. So now, instead of not having an option to audit actions by users, you might face the opposite problem - too many ways to audit! You can read more about the options you have for tracking users here: http://msdn.microsoft.com/en-us/library/cc280526(v=SQL.100).aspx  In SQL Server 2008, we introduced SQL Server Audit, which uses Extended Events to really get a simple way to implement high-level or granular auditing. You can read more about that here: http://msdn.microsoft.com/en-us/library/dd392015.aspx  As with any feature, you should understand what your needs are first. Auditing isn't "free" in the performance sense, so you need to make sure you're only auditing what you need to. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• "Missing Operating System" after installing Ubuntu 12.04 from a CD on a Macbook Pro

  - by Pierre

  I followed this guide to install Ubuntu 12.04 on my Macbook Pro 8,2 (late 2011): https://help.ubuntu.com/community/MactelSupportTeam/AppleIntelInstallation I used a CD. I synced the partition table on rEFIt, and it went fine. I do have an icon to boot on Linux, but when I launch it, after a few seconds I have "Missing Operating System" displayed, and that's all... How can I fix that? The only thing I see is, in the guide, it is mentioned this: On the last dialog of the installer, be sure to click the “Advanced” button and choose to install the boot loader (grub) to your root Ubuntu partition, for example /dev/sda3. This will be the only partition with the EXT4 file system. In Ubuntu 12.04 installation process, there is not such an option, but there is a dropdown menu to select where the grub bootloader should be installed. It was /dev/sda by default, but I selected my root Ubuntu partition (in my case, /dev/sda5). I got a warning message (but actually, it was the same warning message even when I selected /dev/sda), and I continued the installation... Thanks in advance for your help!
