• Fatal X server error: Failed to submit to batchbuffer

  - by Jan

  Ubuntu 10.04 Lucid Lynx used to run fine on my computer. Since a few weeks, my X server crashes out of the blue while the computer is idle and I'm logged into a Gnome session. (I'm then greeted with a new GDM login prompt). After the crash, /var/log/gdm/:0.log.1 has the following: Fatal server error: Failed to submit batchbuffer: Input/output error Please consult the The X.Org Foundation support at http://wiki.x.org for help. ~/.xsession-errors.old has symptoms of X clinets dying: nm-applet: Fatal IO error 11 (Die Ressource ist zur Zeit nicht verfügbar) on X server :0.0. dmesg says: [191848.390081] [drm:i915_hangcheck_elapsed] ERROR Hangcheck timer elapsed...

How would I debug this? Edit: There's a relevant bug on LP.

• `wget` is not recognized or either can't find the file

  - by clankill3r

  if i use cd C:\Program Files (x86)\GnuWin32\bin then i'm able to use wget commands for example: wget http://www.ultralightnews.com/trikes/images/trikes/dfs-singletrike.jpg but i can't find the file back, i looked in c:\ and in the bin folder mentioned above and in GnuWin32\etc If i try wget -O C:\Users\clankill3r\Downloads\wgetfolder wget http://www.ultralightnews.com/trikes/images/trikes/dfs-singletrike.jpg then it says Permision denied, i did allow all permisions possible for every group / user. Some people say it downloads to the current folder your working in (that's why i looked in the bin). But i thought let's try to run the command from another folder so i used: 'cd C:\Users\clankill3r\Downloads\wgetfolderand then the wget comman but then it says thewget` command is not recognized. can someone help?

• What am I missing about PHP?

  - by Aerovistae

  It's like this mythical thing that a dominating portion of developers say is just the best option for back-end development, a part of development about which I know virtually nothing beyond the absolute basics. So I've looked up PHP tutorials a bunch of times, trying to figure out why it's so powerful and common, but it's annoying as hell-- all the tutorials treat you like a new programmer. You know, this is how you make an If Else statement, here's a for loop, etc. The "Advanced Topics" show you how to make POST and GET statements and whatnot. But there must be more to it! I don't get it! That's practically no different from JavaScript. What am I missing about this language? What else can it do? Where's the power and versatility? I've heard it called a function soup; where are all the functions? Please chide me. I'm clearly missing something.

• How to promote an open-source project?

  - by Shehi

  First of all, I apologize if this is the wrong section of network to post this question. If it is, please feel free to move it to more appropriate location... Question: I would like to hear your ideas regarding the ways of open source projects being started and run. I have an open-source content management system project and here some questions arise: How should I act? Shall I come up with a viable pre-alpha edition with working front- and back-ends first and then announce the project publicly? Or shall I announce it right away from the scratch? As a developer I know that one should use versioning system like Git or SVN, which I do, no problems there. And the merit of unit-testing is also something to remember, which, to be frank, I am not into at all... Project management - I am a beginner in that, at best. Coding techniques and experiences such as Agile development is something I want to explore... In short, any ideas for a developer who is new to open-source world, is most welcome.

• Is Rsync like subversion, but for a server?

  - by johnlai2004

  I'm trying to learn how to use rsync. I want to create daily backs up of my production server. Right now I run the command rsync -azr /var/www/* [email protected]:/var/www Now let's say one day, I want to roll back the /var/www/ directory on my production server to last month's version. How do I tell rsync to retrieve version N? On reading that rsync only copies differences between src and dest, I assumed rsync works like subversion where you commit changes to a destination, and keep track of every version, and with the option to checkout any version at anytime. Is that the way rsync works? It's like subversion but for an entire server? That would be great because then it means I don't have to do full ssh copies for my nightly backups.

• latency, regular alternations. Pfsense, network

  - by Tillebeck

  Any idea why grapgh is a shown? It i two pfsense boxes and I have not looked into where they ping to and if it is related to the server they ping. Trafic graphs are following a normal 24 hour cycle and not related to either of the latency graphs Img1: High frequent ulteration in latency. Just started a few days back. Peaks are not perfectly regular but varies from 40min to 1hour Img2: This is a different router on another internet connection. Most of our routers shown this kind of latency graphs - so for our setup it is "normal". Please note that second graph is for a whole week and not just some hours

• How can I retrieve data from a Western Digital Passport External Disk which is not getting recognized but getting shown as healthy in Device manager

  - by Rabimba Karanjai

  When I plug in this external harddisk It is not getting shown in the My Computer. But it gets shown perfectly well in the Device Manager When I go into the Computer Administrative panel and into the disk manager it asks me to initialize the disk Now when I try to initialize it, regardless of the method I try it shows me an error "Incorrect Function" As you can see windows tells me it is working properly. Is there anyway I can retrieve data from this?/access it? I have googled and it seems to be a frequent problem with WD drives. Anyone has any solutions on how I can get the data back?

• Equivalent of phpMyAdmin for MSSQL?

  - by Tedd Hansen

  Is there any webinterface for administrating MSSQL similar to phpMyAdmin (for MySQL)? I want a self-service setup where developers can create a database through webinterface and upload/download backups of the database without local access. I've considered phpMSAdmin, but it hasn't had a release since 2006 so I'm not sure its worth the effort of setting it up. If there is something else (free or not-so-free) that would be great. My question is similar to this one posted 2 years ago, but no good webinterface was found back then. SQL Web Data Administrator seems interesting, but it lacks a few features - most notably creating new databases (also, not updated since 2007).

• e-mail no longer coming to aol inbox since I opened a Hotmail account [closed]

  - by Dave

  I recently set up an email account with Hotmail. I have used AOL e-mail for years and would like to keep this as my main source for sending/receiving e-mail. When I set up the Hotmail account there was an option to have all my e-mail accounts forwarded to the Hotmail inbox. I set up this option and the page promised that all incoming mail would still be visible in the original inbox, in this case my AOL account. Well everything does come to the Hotmail account, the only problem is that I no longer receive these e-mails in my primary/desired location which is AOL. I went back and made sure the box was checked that provided the option through Hotmail that said "leave a copy of my messages on the server" (AOL) How do I get the e-mail that is being forwarded to Hotmail from my AOL account to still be visible in AOL, it should be in AOL inbox as that is the original destination but it is gone. Suggestions?

• Time machine link error

  - by robinjam

  When attempting to perform a Time Machine backup, the backup appears to proceed as normal, until it finishes copying files at which point it complains that an "error occurred while linking files for" one of my external hard disks. During the previous backup that particular disk was in fact empty, and therefore I can't understand why Time Machine is attempting to link back to it. But alas. I've verified all my disks using Disk Utility and they all appear to be fine. Does anybody know what causes this error, and how I might go about fixing it? Failing that is there a way to force Time Machine to create a brand new backup rather than an incremental one? Thanks in advance!

• Skip CodedUI Tests, use Selenium for Web Automation

  - by Aligned

  Originally posted on: http://geekswithblogs.net/Aligned/archive/2013/10/31/skip-codedui-tests-use-selenium-for-web-automation.aspxI recently joined a team that was using Agile Methodologies to create a new product. They have a working beta product after 10 or so 2 week sprints and already had UI’s that had changed several times as they went through iterations of their UI. As a result, the QA team was falling behind with automated tests and I was tasked to help them catch up and expand their tests. The project is a website. I heard many complaints about how hard it is to work with CodedUI (writing our own code, not relying on the recorder as we wanted re-usable and more maintainable code) then it took me 4+ hours to fix one issue. It was hard to traverse the key and debugging the objects with breakpoints… I said out loud “there has to be a better way or a framework the uses jQuery to run through the tests.” Plus it seemed really slow (wait… finding the object … wait… start putting in text…). Plus some tests would randomly fail on the test agents (using the test settings and an automated build, they are run on VMs using Microsoft test agents). Enough complaining. Selenium to the rescue (mostly). The lead QA guy decided to try it out and we haven’t turned back. We are now running tests in Chrome and Firefox and they run a lot faster. We had IE running to, but some of the tests were running fine locally, but hanging on the test agents. I’ll add some hints and lessons learned in a later post.

• Invoke host's workspace switcher from inside VM

  - by Paul

  When I start a virtual machine (like VMware or VirtualBox) and set it full screen then, from the host OS (in this case Ubuntu), I can beautifully switch to it with the Workspace Switcher. So I switch to the VM like I switch to a virtual screen. But switching back -- from the VM to the host's virtual screens -- seems to be impossible because by entering the VM I loose the host's workspace switcher. Is there a nifty workspace switcher program that runs inside the VM and is able to switch workspaces of the host machine? Edit in light of Frank Thomas' answer, can we configure VirtualBox (or VMware) to not send certain key combinations to the VM, but keep them to the host? Like Super+S. In that approach I would sadly have to miss the nice workspace switcher icon in the guest OS, but that's OK if at least the keyboard trick would work.

• SSD on USB 3.0 doesnt always mount

  - by juergen

  I would like to ask you for some support for this issue. The SSD I use is apparently slightly damaged. Atm it shows this popular Corsair Series 3 problem. symptom: the disk is working for some minutes and then just suddenly stops. Two months ago it worked like a charm. This was my boot device in these days. So now I still need to copy some data out of the device which leads me to my question. Usually the SSD is working again for some minutes, when i unplug and replug its power. It gets detected by the system again and I can continue my backup. The problem on Ubuntu is, that it is not recognized again after two or three replugs. I have to reboot to bring it back. To specify this situation: when i unplug and replug my USB mouse before i reboot it is not recognized as well. So something seems to be wrong with the system also. my question: how do i fix this rebooting issue? I will post all the logs you need to analyse. The problem doesnt depend on the interface. I tried USB3.0, 2.0 and Sata already. Thank you! cheers my system: Ubuntu 11.10, Gigabyte G41MT-S2P, Intel E6750 Corsair Force Series 2 - F120, Digitus USB 3.0 Adapter, USB 3.0 interface card

• Microsoft SQL Server Management Studio not working after installing .Net Framework 4

  - by smith watson

  Yesterday I installed .Net Framework 4 as it was required by Liquid XML Studio, but just after installing it, My SQL Server Management Studio stopped working. As soon as open the IDE I get package microsoft sql management studio package failed to load I tried pretty much all the solution posted on the internet but could not get it working, today when I removed the .Net Framework 4, SQL server management studio started working again. Then just to test, I installed the .Net Framework 4 back ... and I started getting the same problem in management studio. I want both on my machine ! how can i do it ? PS : OS is Windows 7

• VIM: How do you get the last ex command you used?

  - by TrevorBoydSmith

  I find that sometimes I write a really long ex mode command that do lots of stuff. They are sort of "mini-scripts" that I write in the text editor then I start ex mode and copy them into the ex line and execute. But then I always end up editing in the ex mode and then I find it difficult to get the changes i did in ex mode back to my text editing session. Using the keyboard, how do you copy the last ex command you used and paste it into your text editor? (Note: This is sort of the opposite of this question "how do I copy/paste in vim ex mode" where the user asks "how do you copy from the text editor and paste INTO the ex mode?". My question is the opposite because I wish to copy from the ex mode and paste into my text editor.)

• How to customize the initrd embedded in or coming with the kernel image

  - by STATUS_ACCESS_DENIED

  I would like to add some tools and not just kernel modules into the initrd (initramfs-based). Now I'm aware of how to unpack and how to pack the initrd with cpio and have even written a hook for /etc/initramfs-tools/hooks in the past to integrate a third-party kernel module. However, while the available script libraries seem to be geared towards the integration of modules, none of them seems to be for integration of other entities (in particular programs and their dependencies). What options do I have to automate the integration of some useful tools for recovery into the initrd? I'm talking about the "rescue" system that the system drops into if it is unable to mount the root drive given to it by the boot loader. Please note that I don't want the SquashFS approach as is used for Live-CDs because for the issue at hand it will be by far sufficient to include some relatively small tools that aid in recovery of the system (when it gets stuck in initrd and can't boot further). Also, the machines when they run into the issue that we have had in the past tend to boot into the rescue system, but there a few tools are missing to kick the system back on trail ...

• Laptop Backup Software (Corporate)?

  - by Hutch

  I wondered if any of you who have a fleet of laptops are using anything to back them up, and if so what? In particular I'm looking for a solution that is totally hands-off once installed i.e. the user doesn't have to do anything, press anything, remember to change something when their domain password changes etc. Right now we use Druva Insync which I have to say is pretty damned good, however our license is up for renewal in a couple of months so I want to be sure it's the best solution before renewing - the only other vaguely comparable product that I know of is from Atempo but the cost of a SQL Server license is a big problem there. Thanks.

• pptp VPN, routing

  - by Adrian

  Details: eth0 = current internet port pptp1 = VPN connection, if I connect to my provider, he give me an IP address, which is accessible from the internet. This is what I need. I want to connect through this IP back to my PC. I want to keep my primary internet connection (eth0) on my PC for all traffic, but route traffic to VPN for specified application/or port, to access application/port from the IP, which I given from the pptp provider. Huhh? Difficult but, it is possible? If yes, how? Incoming port will be always: 33340 Outgoing port can be change, but usually it is 33330

• Grub problem - Command prompt

  - by RhZ

  Update: Thanks to all who helped. I gave up and am going to re-install. Not the end of the world, no files will be lost :-) This time will be backing up grub haha. Thanks again, I really appreciate the community's help on this. I was going along fine when the new pae kernel came down, and it had some bug where the sound was all messed up. So I used startup manager to choose the older pae kernel and rebooted. But startupmanager must have fuXXored my grub. When I re-booted, I get thrown directly into memtest and thats it. I tried to re-install grub using the live disc method that I found in many places. That changed something so I get a prompt and the message: "GNU grub version 1.99 ubuntu. Minimal BASH-like editing is supported. Type help for complete list." But then I tried the live CD fix again and now am back at the memtest... What can I do to get my system running again? UPDATE: Just to be clear,when I start up I get a blinking cursor in the top left, and the word 'ON' in the middle of the screen. Then, after a good minute or two, the memtest starts.

• How do I reset the $PATH variable on Mac OS X?

  - by Neil

  I've messed up my path variable, and now some apps that I run raise errors saying Command Not Found (error 127) for commands like 'date' and 'sleep'. These commands work fine when executed directly in the shell. I'm guessing this has something to do with a malformed $PATH variable, and need to know how to reset it. I've deleted the files ~/.bashrc , ~/.bash_profile, /etc/bash.bashrc, and ~/.bashrc and ~/.profile. What other files could hold my $PATH? Is there some simpler way to reset the Path than dig into the myriad files which could hold my path? Note, this path problem is only with my user. I made a test user on my system, and the path was fine, back to normal.

• Is learning C# as a first language a mistake?

  - by JuniorDeveloper1208

  I know there are similar questions on here, which I've read, but I recently read this post by Joel Spolsky: How can I teach a bright person, with no programming experience, how to program? And it got me thinking about my way of learning and whether it might actually be harmful in the long run. I've dabbled with various languages but C# is my first serious one, I've read "Head First C#" and created a few projects. But after reading the post above I've found it a bit disheartening that I may be going about it all wrong, obviously I respect Joel's opinion which is what has thrown me a bit. I've started reading "Code" as recommended in the reading list and I'm finding it pretty hard going, although enjoyable. I feel like it's taken the shine off of my "noobish hacking about" in Visual Studio. So now I'm unsure as to what path I should take? Should I take a step back and follow Joel's advice and start reading? I guess my main aim is just to become a good programmer, like everyone else, but I don't want to be going into bad practice by learning a .NET language when someone who's opinion I respect thinks that it is harmful. Thoughts?

• Is there an application that can automatically set Graphics Properties when docking?

  - by Ken Liu

  I have a dual display setup with my laptop (Dell, with integrated graphics, WinXP). The problem is that whenever I hook up the laptop to the monitor I have to go to Graphics Properties (Intel Graphics Media Driver for Mobile) and set the display resolution, window position, etc. Note that this screen is different than the built-in one you usually see in WinXP. 1) Is there an app that can save display settings properly so they will come back when I dock again? 2) Barring this, run a script or a macro to automatically set up the display the way I want it. 3) Or, can I write a .Net program that does this for me? Extra points if there is an Open source app that can do this.

• Open file in local text editor from within an SSH connection

  - by Sam

  I'm not a vim guy. I'd like to be able to open log files in Sublime Text when in an SSH connection from within Terminal. Is there a way I could do this? I'm thinking there must be a command or something that could copy the file over to a temporary directory in OS X and then open it in Sublime Text, and when I save it, it'll copy back to the original location through SSH; similar to how FileZilla does it. I'm on Mac OS X MT. The server I SSH into is running Ubuntu. I'm using Terminal.

• Can DRM-free Kindle books still be read on the Kindle app for PC?

  - by verve

  I bought a bunch of Kindle books which I read in the Kindle for PC app but it's too restrictive so I want to try to convert them into another format but I'm worried whether the books will no longer function in the Kindle for PC app? Once you convert a Kindle book will it lose formatting etc.? Can it be re-converted back into the Kindle format once it has been converted? And, more importantly will Kindle book with a broken DRM work in the PC app? Win 7 Pro. Kindle for PC 1.8.3.

• DD-WRT Router Can't hold a connection after initial setup...

  - by AC

  Struggeling with my new DDWRT router (Buffalo WZR-HP-G300NH) configuration. I configured it using one machine while comparing the settings on my existing Linksys WRT54GL on another machine. To the best of my knowledge, I've set it up the same way as my Linksys, but DDWRT has so many other options. After configuring it, I plugged it into the modem, VOIP device & my network. I see the phones come back online. However after a few minutes, it seems I lose the outbound connection (phones die and I can't get out over HTTP). What's confusing me is it works for a few minutes, then it fails. No idea what to look for. Ideas?
