  • cPAddons version conflict with Wordpress

    - by Joel Alejandro
    I have multiple users on my CentOS 5.7 server with WHM/cPanel, who have installed WordPress 3.2.1, and eventually did a manual update to 3.3.1, from Wordpress itself. Now the version of WP for those users doesn't match th one detected by cPanel, and of course, "Upgrade" doesn't work because the directory can't be cleaned (WP is already working there). I've looked on the .cpaddons folder of each user account, and there's a YAML file there, but I'm not sure how can I touch that file for solving this issue. Is there any way to tell cPanel that those WP installations are in fact, 3.3.1?

  • Remote RAID Control ESXi Dell PowerEdge 2950 OpenManage

    - by yoyomommy
    I was wondering how one can add a drive into an existing RAID array while ESXi is still running. I have read that you are able to use Dell OpenManage to do this. I have installed OMSA 7.0 on the VMWare ESXi host (5.0 and fully updated) and I've installed OpenManage Essentials on a Windows Server 2008 R2 guest. The issue that I'm having is that OpenManage is unable to see my RAID controller. I have seen videos and photos as parts of guides on how to do this online, so I would assume that the functionality exists and I just have it set up wrong.

  • "SC.EXE config" and dollar sign in service name

    - by Joe Schmoe
    Say I want to make Windows Service startup dependent on SQL Server. In my case service name for SQL Server is MSSQL$SQL11 (SQL11 is SQL Server instance name) However, when I issue this command: SC.EXE config MyService depend= MSSQL$SQL11 everything after the dollar sign is ignored. When I go to "Dependencies" tab in "Services" SQL Server is not listed. When I check matching registry key it becomes clear why: it only has MSSQL. At this point I have to edit registry by hand to change MSSQL to MSSQL$SQL11 and then everything works as expected. Putting quotes around MSSQL$SQL11 doesn't help. Is there a way to specify $ in the middle of the SC.EXE argument string?

  • DFS share Access denied for some time after workstation is booted.

    - by Jonathan
    I have 2 Win server 2008 servers acting as domain controllers and Dns servers doing DFS. All my workstations are windows xp sp3. I have a DFS share drive mapped at login via login script. After the pc is booted I get an access denied message when trying to access the mapped drive. If i go to the file share on one of the servers i can get to it fine. After about 10 minutes i can try to access the mapped drive again and it works fine. I am not sure if it is some delay happening in dfs name resolution or a gpo issue.

  • windows 7 no internet access

    - by Kyle
    Just did a fresh install of Windows 7, and the network and sharing center says no internet access. Disabling and enabling the adapter seems to fix the issue temporarily, but the internet stops working shortly after. I have installed the latest NIC drivers and have installed all Windows updates. I have also tried manually setting the ip/gateway/dns and running netsh int ip reset in an elevated command prompt. I am running Windows 7 Home Premium 64bit with a wired connection. I have searched for hours, but have found no working solutions. Does anyone have any ideas?

  • How to implement curved movement while tracking the appropriate angle?

    - by Vexille
    I'm currently coding a 2D top-down car game which will be turn-based. And since it's turn-based, the cars won't be controlled directly (i.e. with a simple velocity vector that adjusts its angle when the player wants to turn), but instead it's movement path has to be planned beforehand, and then the car needs to follow the path when the turn ends (think Steambirds). This question has some interesting information, but its focus is on homing-missile behaviour, which I kinda had figured out, but doesn't really apply to my case, I think, since I need to show a preview of the path when the player is planning his turn, then have the car follow that path. In that same question, there's an excellent answer by Andrew Russel which mentions Equations of Motion and Bézier's Curve. Some of his other suggestions of implementation are specific to XNA though, so they don't help much (I'm using Marmalade SDK). If I assume Bézier's Curve as the solution of choice, I'm left with one specific problem: I'll have the car's position (the first endpoint) and the target/final position (the last endpoint), but what should I use as the control point (assuming a square/quadratic curve)? And whether I use Bézier's Curve or another parametric equation, I'd still be left with another issue: the car can't just follow the curve, it must turn (i.e. adjust its angle) accordingly. So how can I figure out which way the car should be pointing to at any given point in the curve?

  • Recovering/Rebuilding MySQL .FRM, .MY* files from IBDATA1

    - by Synetech
    I recently had an incident in which several MySQL files were wiped out (mostly from WordPress, but also a few of MySQL’s own files). The IBDATA1 file is unaffected, but several .frm are gone as are a few .myi and .myd files. So now I need to find out if there is a way to rebuild the missing files from IBDATA1. I tried Googling it, assuming that such an issue has come up before, and indeed there were numerous search results (including this question), but all of the ones I looked at were the opposite, about recovering from .frm and .my* files or somehow required these files. Is there a way to rebuild these files? I know I have a relatively recent backup (a .SQL file) if there isn’t, but I’m hoping that these are the kind of files that are rebuilt if missing or outdated.

  • After restoring a SQL Server database from another server - get login fails

    - by Renso
    Issue: After you have restored a sql server database from another server, lets say from production to a Q/A environment, you get the "Login Fails" message for your service account. Reason: User logon information is stored in the syslogins table in the master database. By changing servers, or by altering this information by rebuilding or restoring an old version of the master database, the information may be different from when the user database dump was created. If logons do not exist for the users, they will receive an error indicating "Login failed" while attempting to log on to the server. If the user logons do exist, but the SUID values (for 6.x) or SID values (for 7.0) in master..syslogins and the sysusers table in the user database differ, the users may have different permissions than expected in the user database. Solution: Links a user entry in the sys.database_principals system catalog view in the current database to a SQL Server login of the same name. If a login with the same name does not exist, one will be created. Examine the result from the Auto_Fix statement to confirm that the correct link is in fact made. Avoid using Auto_Fix in security-sensitive situations. When you use Auto_Fix, you must specify user and password if the login does not already exist, otherwise you must specify user but password will be ignored. login must be NULL. user must be a valid user in the current database. The login cannot have another user mapped to it. execute the following stored procedure, in this example the login user name is "MyUser" exec sp_change_users_login 'Auto_Fix', 'MyUser'   NOTE: sp_change_users_login cannot be used with a SQL Server login created from a Windows principal or with a user created by using CREATE USER WITHOUT LOGIN.

  • Why do I get error 0x0070004 when trying to update to Windows 8.1 from Windows 8?

    - by Jeffrey Lin
    So, I'm trying to update Windows 8 to Windows 8.1 via the Windows Store, but every time I attempt to, the update downloads properly, but then I get the error: Windows 8.1 This app wasn't installed - view details When I click on it, it says: Something happened and the Windows 8.1 could not be installed. Please try again. Error code: 0x80070004 Try again Cancel Install What does this mean? A quick Google search yields nothing. I have tried rebooting, clearing the store cache, and resetting Windows Update. A quick chkdsk scan shows no errors. A SFC scan shows that there are many issues. http://pastebin.com/TZiH8ZXZ Could this be the issue? I found the error log! http://pastebin.com/BXZEsejm Why is the registry corrupt?

  • How do I install a CentOS 5.5 in Xenserver?

    - by deweller
    When I try to install CentOS 5.5 in a new VM, I get an error that the installer is unable to retrieve stage2.img. I have verified the URL and I am able to download this file from a web browser. I suspect it is a networking/routing issue, but I can't figure out what is wrong. This is a new install of XenServer 5.6 on a new server. This server is remote, so I don't have physical access to the box - only ssh access. Can anyone give me some tips on what might be wrong here? Do I need to do something special to get a net install to work? For what its worth, I see the same error trying to install Debian Woody using a similar process. Thanks.

  • Win 7 - Restore Favorites in Windows Explorer

    - by oceola
    Hi all, have this issue - the Favorites link in windows explorer doesn't work. I can't drag and drop anything to it, I can't 'Add current location to Favorites'. Clicking on 'Restore Favorites' does nothing. I can't remember when this started, but I assume I accidentally deleted the Favorites folder. I should probably mention that my user profile is ntfs-junctioned to D:\Users\myname. I tried creating a new Favorites folder, giving it all possible permissions, but that doesn't work. I tried to look in the registry, under HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Explorer\Shell folders HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Explorer\User Shell folders HKEY_USERS\.default\Software\Microsoft\Windows\Current Version\Explorer\Shell folders HKEY_USERS\.default\Software\Microsoft\Windows\Current Version\Explorer\User Shell folders I played with the values in there (pointing to C:\Users\myname\Favorites, D:\Users\myname\Favorites), but nothing seemed to help. Any help would be much appreciated.

  • Typing lag in WinXP

    - by Ssvarc
    I'm working on a Dell Vostro 1000 laptop that has a mysterious lag in typing. You enter keystrokes and it takes a while to show up on the screen. WinXP Pro was freshly installed and the behavior is still here. Here is the weird part... I've tested the computer with the full Dell diagnostic suite, Prime95 (using UBCD4Win), and Memtest86. Everything checks out as fine. If I run a LiveCD such as UBCD4Win or Ubuntu (9.04?) then there is no typing issue. This is causing me lots of aggravation. Thoughts?

  • Apache out of memory on

    - by Sherif Buzz
    Hi all, I have a VPS with 768 MB RAM and a 1.13 GHZ processor. I run a php/mysql dating site and the performance is excellent and server load is generally very low. Sometimes I place ads on Facebook and at peak times I can get 100-150 clicks within a few seconds - this causes the server to run out of memory : Cannot allocate memory: couldn't create child process: /opt/suphp/sbin/suphp .... And all users receive an error 500 page. I am just wondering if this sounds reasonable or not - to me 100-150 does not seem to be a number that should cause apache to run out of memory. Any advice/recommendations how to diagnose the issue highly appreciated.

  • Video Card needs additional mounting support

    - by Sean
    We are creating a fairly decent system with crossfire. The issue we are having is apparently the video cards are physically to heavy to be supported purely by the motherboard and case mounts. Whenever we have the case horizontal everything works fine however when we bring the case upright the computer stops working. Relevant Info: Video Cards (2) - Sapphire 5870 (http://www.newegg.com/Product/Product.aspx?Item=N82E16814102856) MotherBoard - Asus M4A79T Deluxe Case - CoolerMaster 922 HAF To me it looks as if an additional support bracket that could hold up the end of the card would be required (included with the viideo cards!!!) Does anyone have any experience with this.

  • Open FDF document on Mac

    I'm having the issue documented here: http://forums.adobe.com/thread/445594 When I try to open a FDF, I just get a pop up over and over again which asks me if I want to open the form. One possible solution is downgrading to Safari 3, but that is not proven to work. I thought maybe I could get the FDF to open in FireFox, but changing the default browser does not affect Reader, it still attempts to open the FDF in Safari (strange). So, does anyone know of a way to open this form? Thanks -Corey

  • Mouse scroll wheel in Citrix

    Hi all, One of my users is experiencing a problem whereby the mouse scroll does not work on the Citrix published application. I have tried to install mouse drivers on his local PC as well as swapping the USB with a PS/2 mouse but still no go. I have researched this issue for a few days but have not been able to find a fix. PC is running Windows XP and ICA client is version 10 I am pretty sure its a problem local to that PC since every other user using the application published on the same server are not having any issues. What could it be?

  • Code Bubbles: Disruption comes to the IDE

    - by andrewbrust
    If you’re like me, you might see the open source Eclipse IDE as a copy or, more generously, a port of the Microsoft’s Visual Studio for the non-.NET world.  It’s not that Microsoft invented the IDE (I would credit Borland with that), but they really took the idea and ran with it for the first version of Visual Studio .NET in 2002.  The question is whether someone outside of Microsoft could take the modern IDE yet another major step forward in both principle and productivity. I think that has actually happened already, and I think the innovator in question is a second-year Computer Science PhD student at Brown, named Andrew Bragdon.  His project, which he calls Code Bubbles, is an IDE that allows for editing, debugging and exploration of code in “bubbles” which remind me a little bit of the discrete note tiles on OneNote…but they’re much more than that.  Bubbles actually allow for call stack traversal, saved debug sessions, sophisticated breakpoint and value watch behaviors and more.  And because bubbles, unlike windows, are borderless, and focus on code fragments rather than whole files, the de-cluttering effect is unbelievably liberating.  The best way to understand what Code Bubbles does is to watch the screencast video:     Code Bubbles is an IDE for Java development.  Why didn’t Microsoft come up with something like this for .NET devs?  Between the existing features in Visual Studio 2010, its WPF code editor, and the fact that OneNote’s UI bears some affinity to Code Bubbles’, it’s interesting that Microsoft still has not thought outside of its own “box” to get us something like this. Heck, that’s easy for me to say.  But it’s easy for you to say that you’d like something like this in Visual Studio sometime soon.  That’s because the ASP.NET site within UserVoice is taking votes on this very issue.  Just click this link and vote! Thanks to my fellow Microsoft Regional Director Sondre Bjellås for making me aware of Code Bubbles, and to RD Steve Smith for creating the UserVoice voting option.

  • mac osx cannot connect to windows 7 machine

    - by Binary X
    I have a Mac OSX (Snow Leopard 10.6.6) setup on a network with several Windows 7 machines. When trying to place a large file on a Windows share the connection to the Windows share gets lost and I am unable to reconnect until I reboot the Mac. I know this is on the Windows side because the Mac can connect and transfer files to Server 2008 and XP without issue. Looking in the log file I see this message SharePointBrowser::handleOpenCallBack returned 12 I have tried restarting the com.apple.netauth.sysagent service but that did not resolve the situation. I can do an nslookup to the Windows 7 machine, but trying to ping the machine by hostname always gives a hostname lookup failure (I can ping via IP address). I cannot connect to the machine via IP adress either. Any help would be appreciated.

  • dual boot Windows 7 and Ubuntu 11.04, black screen when loading Windows

    - by Sean
    I am proficient with Windows and not so much with Linux. Here is my story: Original system came with Windows 7, got openSUSE installed on the second hard drive, and dual boot for this setup worked fine. Wanted to switch to Windows 7 and Ubuntu 11.04 dual boot so I did a Windows system recovery and it appeared to give me back a fresh Windows 7 install. I then go to install Ubuntu 11.04 and the installer informs me I have multiple operating systems already installed. I go to the advanced partitioning option and sure enough Windows 7 is on /sda while openSUSE is still on /sdb. From here I followed this guide (How to dual-boot Linux and Ubuntu with two hard drives) after I had deleted all the openSUSE partitions on /sdb through the Allocate Drive Space tab of the installer. I make the /boot, swap, /, and /home partitions and set the GRUB into the MBR of the second disk (/dev/sdb). Everything installs fine. I reboot, Windows loads automatically, install EasyBCD and add an entry for Ubuntu into the Windows Boot Manager while assigning the type as GRUB2. Reboot the system and it now shows dual booting options for both Windows and Ubuntu. Problem is: while I can use Ubuntu fine when I try to boot into Windows it just gives me a black screen and after a little while the fans start running crazy. If I restart the computer I will sometimes get the message that my system was put into hibernation mode because the temperature got too high (90C) which I presume is in accordance with the fans going crazy. I have linked the output from the Boot Info Script below, any suggestions on how to fix this issue would be greatly appreciated!

  • PHP throwing XDebug errors ONLY in command line mode...

    - by Wilhelm Murdoch
    Hey, all! I've been having a few problems running PHP-based utilities within the command line ever since I enabled the XDebug. It runs just fine when executing script through a browser, but once I try an execute a script on the command line, it throws the following errors: h:\www\test>@php test.php PHP Warning: PHP Startup: Unable to load dynamic library 'E:\development\xampplite\php\ext\php_curl.dll' - The specified module could not be found in Unknown on line 0 PHP Warning: Xdebug MUST be loaded as a Zend extension in Unknown on line 0 h:\www\test> The script runs just fine after this, but it's something I can't seem to wrap my head around. Could it be a path issue within my php.ini config? I'm not sure if that's the case considering it throws the same error no matter where I access the @php environmental variable. Also, all paths within my php.ini are absolute. Not really sure what's going on here. Any ideas? Thanks!

  • Nginx Fastcgi performance issues

    I am running several fastcgi servers behind Nginx. I run 3 Nginx workers and 6 fastcgi servers as upstream backends. When I run load tests of 1 req per sec, I can clearly see that on avarage a reply is 0.1sec, but from time to time there are 3.1 sec responses. It is a suspiciously deterministic number and it happens even at very small loads from time to time. Both CPU and Memory are of no issue at all. Any idea where this delay may be comming from? Any suggestions how to debug this? Many thanks, Barry.

  • Git: Fixing a bug affecting two branches

    - by Aram Kocharyan
    I'm basing my Git repo on http://nvie.com/posts/a-successful-git-branching-model/ and was wondering what happens if you have this situation: Say I'm developing on two feature branches A and B, and B requires code from A. The X node introduces an error in feature A which affects branch B, but this is not detected at node Y where feature A and B were merged and testing was conducted before branching out again and working on the next iteration. As a result, the bug is found at node Z by the people working on feature B. At this stage it's decided that a bugfix is needed. This fix should be applied to both features, since the people working on feature A also need the bug fixed, since its part of their feature. Should a bugfix branch be created from the latest feature A node (the one branching from node Y) and then merged with feature A? After which both features are merged into develop again and tested before branching out? The problem with this is that it requires both branches to merge to fix the issue. Since feature B doesn't touch code in feature A, is there a way to change the history at node Y by implementing the fix and still allowing the feature B branch to remain unmerged yet have the fixed code from feature A? Mildly related: Git bug branching convention
