• Good practice or service for monitoring unhandled application errors for a small organization

  - by palto

  I'm working with multiple software with varying ways of monitoring for errors. When I make software, I usually send email with the stack trace to admins(usually me). Some customer software is monitored by a team who check that a particular batch run was successfull. Other software might not have any monitoring at all(someone will call when things go wrong horribly). Sending emails is good, except when things start going wrong, my mail gets filled fast. Also I don't want to solve the same problem in code for every software. Is there some relatively cheap and low maintenance software or practice to handle this. I want it to be cheap/low maintenance because usually I work alone or in teams of 5 or smaller. For example it would be great if errors would be aggregated so I don't get 10 000 emails when something unexpected happens... For clarification: By unhandled errors I mean Exceptions that were unhandled by application code that were propagated to Tomcat or Jboss. I don't need help with how to catch those errors. I need help with what to do with them. Is there any cloud application that I could send my errors to? Or some simple server to install? Or some library that can handle errors using configuration files. I use Java if that is any help.

• I know how to program, and how to learn how to program, but how/where do you learn how to make systems properly?

  - by Ryan

  There are many things that need to be considered when making a system, let's take for example a web based system where users log in and interact with each other, creating and editing content. Now I have to think about security, validation (I don't even think I am 100% sure what that entails), "making sure users don't step on each others feet" (term for this?), preventing errors in many cases, making sure database data doesn't become problematic through unexpected... situations? All these things I don't know how or where to learn, is there a book on this kind of stuff? Like I said there seems to be a huge difference between writing code and actually writing the right code, know what I mean? I feel like my current programming work lacks much of what I have described and I can see the problems it causes later, and then the problems are much harder to solve because data exists and people are using it. So can anyone point me to books or resources or the proper subset of programming(?) for this type of learning? PS: feel free to correct my tags, I don't know what I am talking about. Edit: I assume some of the examples I wrote apply to other types of systems too, I just don't know any other good examples because I've been mostly involved in web work.

• System speakers not recognized

  - by Kyle Maxwell

  Since upgrading to Xubuntu 13.10, sound has not functioned properly (e.g. screeching when playing Skype notifications). Now, however, it does not function at all. pavucontrol only shows Dummy Output and does not recognize the built-in speakers on my Dell Precision M4600. Possibly related, the sound indicator applet does not come up when I click on it, only showing a small white bar underneath it. I have purged and reinstalled pulseaudio. lspci -v shows: 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04) Subsystem: Dell Precision M4600 Flags: bus master, fast devsel, latency 0, IRQ 56 Memory at f2560000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel 01:00.1 Audio device: NVIDIA Corporation GF106 High Definition Audio Controller (rev a1) Subsystem: Dell Device 14a3 Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at f0080000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel The "Capabilities: <access denied" line makes me wonder if there's a permissions issue, as the Log Out applet now shows "Restart" and "Shutdown" grayed out. groups shows me in: kmaxwell adm dialout cdrom sudo dip plugdev fuse lpadmin netdev sambashare vboxusers

• Ubuntu 12.10 with kernel 3.5.0-18

  - by Chaitanya

  I had ubuntu 12.04 with kernel 3.0.2. Today I have updated my system and got 12.10 with kernel 3.5.0-18. Now when I boot my machine with 3.5 kernel, it starts until the page where I enter my password. Within seconds, I get a page with looooong list of some commands or list. I cant take screenshot of that. It looks something like, [1.2234978942837]kjsahfa;lsfksld;fkjsf;owieurwirejw/rnw;erkjwelrjw2309480432 [1.3294823498230948]as;lfjsf;iuwrijrwjlkerjw;rekwer;lkwjre;lkjRIJWEORIWE'JJA; something like this. Luckily, in my boot page, I have 3.0.2 kernel also. When I boot with 3.0.2 kernel there is no problem. But when I boot with 3.5.0, it throws that wierd error. I wont be able to do anything at that time. None of the keys work. I have to forcibly shutdown the machine and restart with 3.0.2 kernel. Please help..... Thanks, Chaitanya.

• How to debug suspend?

  - by mlissner

  I've been using Ubuntu for about five years now, and I still can't make it suspend when I want to. It's quite irritating that I can program up a storm, hack the machine in numerous other ways, and yet, and yet when I try to make it suspend or debug suspend, I fail miserably. I need help. Where do I begin to find the problem? What do I do to fix it? I'm placing a bounty on this, because I've literally lost hours of my life to this problem, and leaving my computer on ALL the time is terrible. The symptoms: Pressing suspend brings my computer to a state where it has a blinking cursor, the fans are running, it seems that the HD has turned off (I think), and I can't do anything to bring it back from this state (short of a hard reboot). Possibly related: My fans stay on even after a shutdown, and even then, I have to press the power button for five seconds before I can start it up again. I don't know what logs to look at to debug the problem, and I imagine they'd get nuked on reboot anyway. Please, please help. This drives me completely nuts, and I've been living with it for over a year.

• G++ Compiling errors

  - by egn56

  Attempting to do some compiling with g++ and when I run g++ test.cpp this is what I get. I am in the correct directory and I have even messed with the permission settings to make those directories chmod 777 as a test, still nothing. Tried running it as sudo g++ test.cpp and getting nothing. It can compile and create a .o if i run g++ -c test.cpp but it can't seem to link it and create the .out.

• Please help restore my crashed launcher/compizconfig

  - by Will

  I have just upgraded from 11.04 to 11.10. Everything worked fine at first, but at one point when I was editing some CompizConfig settings (just something basic like 'number of desktops'), CompizConfig crashed. Then the whole launcher disappeared, along with most of the buttons in the top panel. The shutdown button, calendar, etc. all went, leaving just the tabs from File to Help. Also, windows now have the title and File, Edit..(etc) tabs on 2 separate lines, instead of the new format where hovering over the bar switches which one is visible. I have since been using Ctrl+Alt+T to open a terminal and open applications, shut down, etc, from there. I have typed in the command: unity --reset which has some effect, but the terminal never reaches the end of the task. I've also done apt-get update, which completed fine. Can anyone help me restore the launcher and panel functions?? I am getting most frustrated by the fact that once I have opened Firefox, I can't enter any other commands!

• Getting the PC speaker to beep

  - by broiyan

  There has been much written on getting the beep sound from Ubuntu releases over the years. Example: fixing the beep My needs are slightly different in that I do not want to ensure sound card beeps are functioning. Instead, I want PC speaker beeps, the kind produced by the original built-in speaker because I believe they will produce less CPU load. I have confirmed that my computer has the PC speaker by unplugging the external speakers and shutting down Ubuntu. At some point in the shutdown and restart process a beep is heard even though the external speakers have no power. I have tried the following: In /etc/modprobe.d/blacklist.conf, turn these lines into comments: #blacklist snd_pcsp #blacklist pcspkr In .bashrc /usr/bin/xset b on /usr/bin/xset b 100 Enable in the gnome terminal: Edit Profile Prefs General Terminal Bell Ensure no "mute" selections in: System Prefs Sound various tabs (uncheck them all). Select "Enable window and button sounds" in: System Prefs Sound Sound Effects In gconf-editor desktop gnome sound, select the three sound check boxes. In gconf-editor apps metacity general select the audible bell check box. Still I get no PC speaker beeps when I send code 7 to the console via my Java program or use echo -e '\a' on the bash command line. What else should I try? Update Since my goal is to minimize load on the CPU, here is a comparison of elapsed times. Each test is for 100,000 iterations. Each variant was performed three times so three results are presented for each. printwriter.format("%c", 7); // 1.3 seconds, 1.5 seconds, 1.5 seconds Toolkit.getDefaultToolkit().beep(); // 0.8 seconds, 0.3 seconds, 0.5 seconds try { Runtime.getRuntime().exec("beep"); } catch (IOException e) { } // 10.3 seconds, 16.3 seconds, 11.4 seconds These runs were done inside Eclipse so multiply by some value less than 1 for standalone execution. Unfortunately, Toolkit's beep is silent on my computer and so is code 7. The beep utility works but has the most cost.

• What went wrong with my curl install?

  - by Danjah

  I'm fresher than the prince to Linux, I've been following the instructions here: http://chrisfulstow.com/running-node-js-on-windows-with-virtualbox-and-ubuntu (the link tells what I am generally trying to do). I'm all up and running in VBox, and am at the curl install part, I may have done the curl part a week ago I forget. So I ran this command anyway: danjah@danjah-VirtualBox:~$ sudo apt-get install curl Result: [sudo] password for danjah: Reading package lists... Done Building dependency tree Reading state information... Done curl is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. Then: $ curl http://npmjs.org/install.sh | sudo npm_install=rc sh Result: fetching: { gzip: stdin: unexpected end of file /bin/tar: Child returned status 1 /bin/tar: Error is not recoverable: exiting now It failed Should I be concerned? How can I test curl? How can I avoid these situations? Perhaps there's a generic way of checking to see if I've already installed packages/etc? Case specific answers and general advice most appreciated. cheers, d

• Restart and/or graphics problem in Ubuntu 12.04

  - by kara

  I having been using 12.04 for a couple of months now, with v. little problems. The other day I restarted my computer, and though I think it rebooted, the screen would be black. I could not even get a visual from a live cd. Finally, I was able to get it to load, but the resolution has been completely off. The computer thinks I have a laptop screen, when I actually have a ViewSonic VP2330wb, and it detects only two resolutions. And still, I have a problem with rebooting. If the screen locks after I leave it for a while, I can't get a visual back, and then when I force a shutdown, it takes 3 times for me to get a grub screen. Then I have to boot in recovery mode, and then finally in normal mode, but the screen is still always off. This is my video card: description: VGA compatible controller product: 2nd Generation Core Processor Family Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list configuration: latency=0 resources: memory:fe000000-fe3fffff memory:d0000000-dfffffff ioport:f000(size=64) I am a new ubuntu user, and am at my wits end.

• Terminal/Putty showing control characters (^M) after updating

  - by jaycee48

  I updated my system yesterday afternoon using the recommended updates from Update Manager. After it completed, I shutdown my system and went home for the day. I come in this morning and I am getting control characters displayed when using vi in both the standard terminal emulator, putty, and putty inside of my Windows virtual that I run with VirtualBox. I have made no other system changes and I cannot figure out how this occurred. It's as if every text file I have was created in DOS. I've searched the forums and I haven't found any answers. I am using xterm as my emulator and I checked with 3 of my coworkers and none of them are having this problem so we do not believe it is a server side issue. Especially since I've checked 3 different servers. There's nothing in my .profile other than PATH variables so I'm using the same terminal settings as everyone else. Some files are fine (I can open and read both /etc/environment and my .profile) but most of any kind of server generated log file is trash. Running cat or head on the same file displays the contents without the characters. Any ideas would be appreciated. Thanks.

• Maximum 5 minute battery life with Ubuntu 11.10 on HP laptop

  - by JamesG

  I apologise if this question is too similar to the numerous others already asked, but it seems that my difference in battery life is significantly more noticeable than others that have been reported. I recently installed Ubuntu 11.10 on my HP Pavilion dv6 laptop (which I purchased brand new just under one year ago). When running Windows 7 on this laptop, I have been able to get up to two and a half to three hours of battery life with wireless disabled and when running only Microsoft Word. However, when running Ubuntu, I am unable to use the laptop if it is not plugged in. Upon unplugging the fully-charged machine from the power cord, if I have wireless enabled, I immediately receive a notification that the battery levels are critically low and that shutdown is imminent. Even if I replace the power plug, the laptop shuts down within thirty seconds. If I disable wireless capability, I am able to run the laptop for an absolute maximum of five minutes on battery powers before receiving the same message. I have tried running with Jupiter on Power Saver mode, but to no noticeable effect. Ignoring the fact that I can't use my laptop without being attached to a power source, I really do enjoy using Ubuntu, and hence would greatly appreciate any help that can be offered.

• Create a custom shortcut that types clipboard contents

  - by briankb

  I want to paste my clipboard contents to a remote session such as VNC, IPMI, or Raritan. To accomplish this, I installed xdotool and clip. Then I wrote a simple command that types the clipboard contents: xdotool type "$(xclip -o)" This works if I stay in a terminal window, and type that command myself. It types back my clipboard contents when I run the command. Of course now I want to make this into a hotkey that works in any window. However, if I create a custom shortcut using Keyboard settings, it doesn't work. If I assign a hotkey Alt+K to the shortcut, nothing happens when I press it. If I use Ctrl+K, unexpected behavior occurs to whatever window has focus. e.g. my terminal window size shrinks (it's somewhat amusing, actually). Similar results occur if I save it as a script and call the script, or if I encapsulate the command with sh -c. How can I make practical use of the powerful xdotool type command?

• Connecting / disconnecting DisplayPort causes crash

  - by iGadget

  I wanted to file a bug about this using ubuntu-bug xserver-xorg-video-intel, but the system prompted my to try posting here first. So here goes :-) While the situation in Ubuntu 11.10 was still somewhat workable (see UI freezes when disconnecting DisplayPort), in 12.04 (using Unity 3D) it has gotten worse. The weird part is that during the 12.04 beta's, the situation was actually improving! I was able to successfully connect and disconnect a DisplayPort monitor without the system breaking down on me. But now with 12.04 final (with all updates), it's just plain terrible. When I now connect an external monitor using the DisplayPort connector on my HP ProBook 6550b, it only works sometimes. Most times (but not always!) the screen just goes blank and the system seems to crash (not even CTRL+ALT+F1 works anymore). Only a hard shutdown by keeping the power button pressed for several seconds and then a restart gets me out of this. I suspect the chances of the system crashing become higher as the system's uptime increases, especially when there have been one or more suspend-resume cycles (although I have also experienced this bug once from a cold boot). Disconnecting is roughly the same as with 11.10 (see issue mentioned above), with the difference that if I resume from suspend, I no longer have to do a CTRL+ALT+F1, ALT+F7 cycle to get my screen back. So what more can I try? Or should I just go ahead and file the bug anyway?

• Migration a database from 32bit to 64bit

  - by Mike Dietrich

  Database migrations from an 32bit environment to an 64bit environment keeping the same platform architecture (e.g. moving an Oracle 10.2.0.5 database from MS Windows XP 32bit to MS Windows Server 2003 64bit) does not happen that often anymore. But still we see them getting done. And there are a few things to note when doing such a move. First of all the important question is:Will you upgrade your database as part of this move - Yes or No? If you say "Yes" then you are almost done with that topic as we will take care of that bitnes move during the upgrade. The only thing you have to take care is OLAP in case you are using OLAP Option with Analytic Workspaces (AW) by yourself. Those store data in Binary LOBs - and in order to move AWs from 32bit to 64bit you have to export your AWs prior to the move - and import them later on. People who don't use OLAP don't have to take care on this. But if you say "No" (meaning: no upgrade actions involved - you keep your database version) then you have to make sure to invalidate all packages and stored code in the database before you shutdown your database in the 32bit environment and prior to moving it over. And the same rule as above for OLAP applies once you use the OLAP Option. In the source environment: startup upgrade;    -- [or startup migrate; -- for Oracle 9i] @?/rdbms/admin/utlirp.sqlshutdown immediate In the destination environment: startup upgrade @?/olap/admin/xumuts.plb --Only if OLAP Option is installed@?/rdbms/admin/utlrp.sql The script utlirp.sql will invalidate all packages and stored code, utlrp.sql will recompile - and xumuts.plb will rebuild the OLAP Analytic Workspaces in case you have the OLAP Option installed.

• Acer Aspire 5542G overheating with ubuntu/kubuntu 12.04

  - by james

  I have an Acer Aspire 5542G laptop purchased couple of years ago. All these days, i used windows 7 on it . Then I tried ubuntu 12.04 . Everything was fine except the overheating issue. I updated ubuntu with all security fixes and available updates but nothing solved the problem. With idle use like internet browsing, the cpu fan speeds up a lot and i can feel very hot air coming from the vent (comparable to playing serious 3d game in windows). But it will not go to a point of freeze and shutdown. But as long as im using it, with no intensive tasks at all, the laptop stays too hot. This wasn't the case with windows7. In windows 7 the fan will not rotate at all with normal use. I heard there was manufacturing defect with some acer laptops, but i think it wasn't the case with my laptop since windows7 runs perfectly. I updated the bios to latest version. I cleaned dust in the vents. I tried kubuntu 12.04 up-to-date. Nothing solved the issue. My laptop specs are: CPU : AMD turion2 x2 M500 @ 2.2GHz GPU : AMD Mobility Radeon HD4570 3GB RAM and 320GB hard disk.

• Are there legitimate reasons for returning exception objects instead of throwing them?

  - by stakx

  This question is intended to apply to any OO programming language that supports exception handling; I am using C# for illustrative purposes only. Exceptions are usually intended to be raised when an problem arises that the code cannot immediately handle, and then to be caught in a catch clause in a different location (usually an outer stack frame). Q: Are there any legitimate situations where exceptions are not thrown and caught, but simply returned from a method and then passed around as error objects? This question came up for me because .NET 4's System.IObserver<T>.OnError method suggests just that: exceptions being passed around as error objects. Let's look at another scenario, validation. Let's say I am following conventional wisdom, and that I am therefore distinguishing between an error object type IValidationError and a separate exception type ValidationException that is used to report unexpected errors: partial interface IValidationError { } abstract partial class ValidationException : System.Exception { public abstract IValidationError[] ValidationErrors { get; } } (The System.Component.DataAnnotations namespace does something quite similar.) These types could be employed as follows: partial interface IFoo { } // an immutable type partial interface IFooBuilder // mutable counterpart to prepare instances of above type { bool IsValid(out IValidationError[] validationErrors); // true if no validation error occurs IFoo Build(); // throws ValidationException if !IsValid(…) } Now I am wondering, could I not simplify the above to this: partial class ValidationError : System.Exception { } // = IValidationError + ValidationException partial interface IFoo { } // (unchanged) partial interface IFooBuilder { bool IsValid(out ValidationError[] validationErrors); IFoo Build(); // may throw ValidationError or sth. like AggregateException<ValidationError> } Q: What are the advantages and disadvantages of these two differing approaches?

• How-To: Run CMSDK against a RAC cluster

  - by frank.closheim

  Using CMSDK in a production environment often requires a robust, reliable and failover enabled repository. When using Oracle Real Application Cluster (RAC) with your CMSDK repository you need to have a specific configuration in place to support such a setup. This post will explain the configuration steps required when running CMSDK 9.0.4.6 with Oracle WebLogic Server (WLS).In the previous CMSDK 9.0.4.2 version a RAC enabled connect string looked like this: (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = rac1)(PORT = 1521))(ADDRESS = (PROTOCOL = TCP)(HOST = rac2)(PORT = 1521))(LOAD_BALANCE = NO)(FAILOVER = ON)(CONNECT_DATA =(SERVICE_NAME = rac)(failover_mode = (type=select)(method=basic)))CMSDK 9.0.4.6 makes use of data sources to connect to the underlying database. These data sources are configured inside your Application Server, such as Oracle WebLogic Server.In Oracle WebLogic Server 10.3.4, a single data source implementation has been introduced to support an RAC cluster. It responds to Fast Application Notification (FAN) events to provide Fast Connection Failover (FCF), Runtime Connection Load-Balancing (RCLB), and RAC instance graceful shutdown. XA affinity is supported at the global transaction Id level. The new feature is called WebLogic Active GridLink for RAC; which is implemented as the GridLink data source within WebLogic Server.This GridLink data source also works with Oracle Single Client Access Name (SCAN). SCAN is a feature used in RAC environments that provides a single name for clients to access any Oracle Database running in a cluster. You can think of SCAN as a cluster alias for databases in the cluster. The benefit is that the client’s connect information does not need to change if you add or remove nodes or databases in the cluster.The CMSDK 9.0.4.6 documentation describes how to create a regular JDBC data source named jdbc/OracleDS. Please refer to the following document which describes in detail how to create a GridLink data source in WLS.

• Managing many draw calls for dynamic objects

  - by codetiger

  We are developing a game (cross-platform) using Irrlicht. The game has many (around 200 - 500) dynamic objects flying around during the game. Most of these objects are static mesh and build from 20 - 50 unique Meshes. We created seperate scenenodes for each object and referring its mesh instance. But the output was very much unexpected. Menu screen: (150 tris - Just to show you the full speed rendering performance of 2 test computers) a) NVidia Quadro FX 3800 with 1GB: 1600 FPS DirectX and 2600 FPS on OpenGL b) Mac Mini with Geforce 9400M 256mb: 260 FPS in OpenGL Now inside the game in a test level: (160 dynamic objects counting around 10K tris): a) NVidia Quadro FX 3800 with 1GB: 45 FPS DirectX and 50 FPS on OpenGL b) Mac Mini with Geforce 9400M 256mb: 45 FPS in OpenGL Obviously we don't have the option of mesh batch rendering as most of the objects are dynamic. And the one big static terrain is already in single mesh buffer. To add more information, we use one 2048 png for texture for most of the dynamic objects. And our collision detection hardly and other calculations hardly make any impact on FPS. So we understood its the draw calls we make that eats up all FPS. Is there a way we can optimize the rendering, or are we missing something?

• Login takes very long, annoying repaints once a minute when logged in: How to troubleshoot?

  - by user946850

  I am suffering from a strange problem with my Gnome Shell in Ubuntu 12.10. The login takes very long ( 30 sec), with a blank screen. In Google Chrome and Thunderbird (and perhaps in other applications), the main window freezes and is repainted in periodic intervals of less than one minute. The freeze takes several seconds, and it seems that font and appearance of, e.g., tabs and buttons briefly changes. Attempting to enable the second monitor show an error message related to XRANDR. Everything seems to have started three days ago, after I had to force-shutdown the machine while it was hibernating due to low power. (It was hibernating for quite a while and didn't want to stop.) Silly me. I have tried the following measures, with no avail: Checked all package file md5 hashes using debsums Reinstalled all packages using a variant of dpkg --get-selection \* | xargs apt-get install -reinstall Temporarily moved configuration directories such as .gconf, .config and .gnome2 to another location Created a new user account When I choose "Ubuntu" during login, the problems disappear. I am sort of frustrated that reinstalling all packages didn't fix the issue. How to troubleshoot this Gnome Shell (?) problem, short of reinstalling the system? (Or did anyone see this kind of behavior on their machine?)

• Randomly Freezes - How Can I Diagnose the Problem?

  - by j0rd4n

  At random times, Ubuntu 10.04 freezes, and I have to do a hard shutdown. It was upgraded from 9.10 which didn't freeze. First, is this is common problem with a quick answer, and if not, what can I do to diagnose it? I've tried checking application/kernel logs, but nothing gives me a clue as to what caused the problem. My guess, is that since the OS froze, no logs could be updated. Ideas? SOLUTION: Solved it. My particular problem was my graphics card (integrated Radeon 9000 series). netconsole revealed I was getting the error: "reserve failed for wait". After trial-and-error, I manually configured my video card and disabled hardware acceleration. Completely fixed the issue. Here is what I did: Manually Created xorg.conf Ubuntu automatically configures xorg.conf and doesn't use a file. To edit this file, you have to tell Ubuntu to explicitly create one and then edit it. Here are the steps: Restart system Hold Shift as GRUB boots Select root terminal in GRUB login menu Execute: X -config xorg.conf.new Copy: cp xorg.conf.new /etc/X11/xorg.conf Disable Hardware Acceleration The following is specific to my Radeon card, but I'm sure other cards have a similar setup. Edit xorg.conf Find "Device" section for graphics card Uncomment "NoAccel" option and set to "True" Save + reboot Hope that helps.

• Applying Service Pack 1 to Team Foundation Server 2010

  - by Enrique Lima

  Disclosure:  I performed the following activities on my Windows 7 SP1 system, Visual Studio 2010 SP1 and a local Basic installation of TFS 2010. As with any deployment of a service pack into a server environment, take your recommended precautions and be aware of the changes you are putting in.  With that said, make sure you backup your databases, and that you have an exit/rollback strategy in the event of an unexpected situation. Team Foundation Server 2010 Service Pack 1 corresponds to KB2182621.  The KB article is http://support.microsoft.com/kb/2182621 The process will be very simple to follow, you will need to execute the mu_team_foundation_server_2010_sp1_x86_x64_651711.exe file.  That will extract files needed and launch the wizard driven Installation. Once this process completes, you need to validate the changes. By looking at Team Foundation Server 2010 Administration Console, you should see the reference to the KB number and SP1. There is also a good reason to validate log locations and records. From the Team Foundation Server 2010 Administration Console. Or from Windows Explorer, go to the C:\ProgramData\Microsoft\Team Foundation\Server Configuration\Logs location and review the logs referenced by the servicing references.

• not being able to access any sudo function on my pc

  - by explorex

  Hi, I am not being to access any functions in my desktop and I don't have an OS besides Ubuntu 10.04 Lucid Linux and I am new to ubuntu. I think I rebooted my computer thinking that Google Chrome crashed. I opened Google Chrome but it showed opening message but never opened so I restarted my computer. and when my system was loading ('i was playing with keyboard dont know what I typed') and when by ubutnu loaded, I was unable to access anything some of characteristics are listed below I cannot hear any sound I cannot access wired ethernet connection on the right corner where I usually enable to access interne and I have no internet. There is no local apache server either. when ever I try to start apacer I get setuid must be root or something. When I type sudo then I get message setuid must be root. I cannot access orther external storage devices like pendrive and portable hard drive and cannot mount my other drives with FAT32 filesystem. When I try to start my apache webserver with out typing sudo then I get message cannnot open socket or something like it. EDIT:: i remember also doing command chown -R www-data / earlier and got error message EDIT:: and i cannot shutdown my computer, it only logs off

• WUBI installation can no longer boot, UUID disk not found

  - by Joel Heenan

  Yesterday my Wubi/Vista installation was working fine. I shut it down at the train station, all good then when I attempted to boot ubuntu at home I got a message saying the UUID for root could not be found. By booting with the Ubuntu live CD I found that the C:\ubuntu\disks folder stat structure was broken, reported as "??? ??? ??" kinda thing. I booted into Windows, scheduled a CHKDSK, ran that on boot which found some errors and rebooted. Still no dice. I am not stressed because it appears my home directory is still there with all my content so I don't mind re-installing the OS (probably will clean it up some). What is the best path from here to repair the WUBI installation? Is there anything else I should do to repair it? I'm looking at whether the drive is dying now to work out why this occured. Possibly I moved the laptop before shutdown had completed.
