  • What are JOINs in SQL (for)?

    - by sabwufer
    I have been using MySQL for 2 years now, yet I still don't know what you actually do with the JOIN statement. I really didn't come across any situation where I was unable to solve a problem with the statements and syntax I already know (SELECT, INSERT, UPDATE, ordering, ...) What does JOIN do in MySQL? (Where) Do I need it? Should I generally avoid it?

  • mget: filename.xlsx: file already existst and xfer:clobber is unset

    - by Chris
    I am getting this: mget: filename.xlsx: file already existst and xfer:clobber is unset error when I try to download the contents of my ftp server. Basically it is setup using cygwin. We recently upgraded the server where all of the data is downloaded to on a set schedule. The old server was Windows server 2003, and the new server is windows server 2008. I am having issues when I try to download a file that is already in the folder. The client never changes the file name, so when we go to download it from the server we get that error. Is there anything i can put in the batch files, or something for it to just force it to replace that file? Thanks in advance

  • How to resolve "svn: Can't find a temporary directory: Internal error"?

    - by HorusKol
    I have already googled the message, and I have plenty of disk space available on the SVN server (it's about 4% usage of 150 GB). I have noticed that when I try echo $TMPDIR at the command prompt on the SVN server I get nothing. What is making this a little confusing is that I only get this message from one location when I do an svn diff (that I've tested so far) - this error is not coming up when I try from three other computers (one of which is testing against the exact same repository, the other two are different repositories on the same svn server). About the only difference I can see is that the broken working copy is connecting to the server by an IP address where all the others are using a server name (although this resolves over DNS to the same IP Address). I'm hoping that I don't have to scratch the broken working copy and checkout a new one - unfortunately, this is a legacy project and not all changes have been properly revisioned.

  • MS Windows Server 2008R2 slow file copy, slow network connection

    - by MattrixHax
    i just setup a windows 2008R2 standard server, with the only installed app being Hyper-V, and only 1 windows XP VM is running. Whenever i try to copy a file from my windows 7 laptop over to the 2008R2 server machine's admin shares ( \\servername\c$ ) the files start transferring around 60mb/s and then drop to around 5mb/s. My windows 7 machine and the server 2008 machine are both in WORKGROUP (no domain here). when i try the same transfer to our server 2003 box the transfer speeds are fine. tried disabling autotuning (netsh interface tcp set global autotuninglevel=disabled) as well as turning off the checksum offload to the adapter (tx and rx) - i still see strange packet errors (bad header checksum) using wireshark and just cannot seem to track down what the issue is - over 1 hour to transfer 4gb of files from 1 server to another that are on the same GB switch is just crazy.... any ideas would be greatly appreciated!

  • Local Flash in Chrome pepper player won't link to internet

    - by No one in particluar
    I have a local .swf file in a local .html file. The flash file opens a popup window when a link is clicked. In Chrome, when I open the html file and click the button, nothing happens. Then when I go to about:plugins and disable the top Flash player (the pepper one) then try refresh and try clicking the button again, nothing happens. Then when I go to http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.html and add the the folder the files are stored in to the list and refresh the page and click the button again, it opens the popup. When I re-enable the pepper flash player, and re-add the folder to the allowed list in flash (it's gone from the list now that I changed players), refresh the page and click the button again, it does nothing. I don't know why it won't open with the pepper player. I'm using Windows 7, Chrome 22.0.1229.94 m, Pepper Flash player 11.4.31.110, and regular Flash Player 11,4,402,287.

  • Can't clone gitosis-admin.git local from my snow leopard server running gitosis

    - by joggink
    I've installed gitosis as described here: http://gist.github.com/264304 One of the things that I had to adjust was to give my git user permissions to use ssh (which I did trough server admin - access - ssh and added the 'git' user). When I ssh from my local machine (mac osx) as the git user, I get this response: PTY allocation request failed on channel 0 bash: gitosis-serve: command not found Connection to 10.0.0.108 closed. Which I think is normal, because in Pro GIT the author says you should get something like this if you try ssh'ing to the server using your git user: PTY allocation request failed on channel 0 fatal: unrecognized command 'gitosis-serve schacon@quaternion' Connection to gitserver closed. So far so good, I think? Now when I try to clone my gitosis-admin.git repository using this command: $git clone [email protected]:gitosis-admin.git I get this: Initialized empty Git repository in /Users/joggink/gitosis-admin/.git/ bash: gitosis-serve: command not found fatal: The remote end hung up unexpectedly So after doing some searching, I found an answer here on serverfault claiming I should use ssh:// as protocol for my git clone (which I thought is the default git protocol?) However, when I try: $git clone ssh://[email protected]:gitosis-admin.git This is the response: The authenticity of host ' (::1)' can't be established. RSA key fingerprint is 80:4d:77:c7:78:cb:c9:42:e3:82:06:7c:fe:c0:08:ce. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '' (RSA) to the list of known hosts.

  • Disk I/O error copying a Exchange 2007 database

    - by Scottio
    Hi all, A short time ago due to disk space I moved our Exchange database onto an external drive, the drive was new and the database was being backed up daily. I've now discovered the database is corrupt, I've run the Exchange utils to fix the database and this works but it corrupts again as soon as I try to move it. I need to get it off the disk, any suggestions? I'm also trying to restore the last good database but I'd like try to get the database off this disk, any suggestions? PS I know putting the db on an external disk was a bad move, I had no where else to put it :-( Thanks

  • DHCP "no answer" on CentOS 6.4

    - by Kev
    I installed a DHCP server (yum install dhcp) and this is my conf: # create new # specify domain name option domain-name "mydomain.name"; # specify DNS's hostname or IP address option domain-name-servers 10.0.1.1, 10.0.1.2; option ntp-servers 10.0.1.1, 10.0.1.2; allow unknown-clients; # default lease time default-lease-time 2628000; # max lease time max-lease-time 2628000; # about a month # this DHCP server to be declared valid authoritative; # specify network address and subnet mask subnet 10.0.0.0 netmask 255.0.0.0 { # specify the range of lease IP address range dynamic-bootp 10.0.2.1 10.0.2.50; # specify broadcast address option broadcast-address 10.255.255.255; # specify default gateway option routers 10.0.0.1; allow unknown-clients; } service dhcp start reports [ OK ]. Yet, if I disable my other DHCP server (Win2k3) and get a client to try renewing its IP lease, it times out. So I installed dhcping. No matter what options I try, including directing dhcping at my server, adding a client address in the range, adding my hardware address, it replies 'no answer'. I'm also trying -i since that seems to be more akin to what a WinXP client would try to do, based on /var/log/messages. It logs the attempts (from dhcping here) as: Oct 24 18:55:13 newdc dhcpd: DHCPINFORM from 10.0.2.15 via eth0:4 Oct 24 18:55:13 newdc dhcpd: DHCPACK to 10.0.2.15 (00:11:25:66:4e:7f) via eth0:4 Oct 24 18:55:13 newdc dhcpd: DHCPINFORM from 10.0.2.15 via eth0:3 Oct 24 18:55:13 newdc dhcpd: DHCPACK to 10.0.2.15 (00:11:25:66:4e:7f) via eth0:3 Oct 24 18:55:13 newdc dhcpd: DHCPINFORM from 10.0.2.15 via eth0 Oct 24 18:55:13 newdc dhcpd: DHCPACK to 10.0.2.15 (00:11:25:66:4e:7f) via eth0 The :3 and :4 are because I have a few extra Host(A) records for this server so it responds on more than one IP for our intranet app. No answer? It sounds like it should be getting three answers...no? (And if that's the problem, how do I limit the DHCP service to replying from eth0?)

  • I removed my-freeze.com NetAssistant, but now can't access two websites

    - by Firefly
    I used "Revo Uninstaller" to uninstall the spyware which left me with a problem using Internet Explorer so then downloaded the free version of "Hijack This" from the website and, not reading the Super User answer correctly, used fix for the general issues it found and saved the log file of the other queries. NetAssistant is completely gone or appears to have - Malwarebytes Malware remover cannot find anything and most Google searches now seem to work correctly. However in removing it I seem to have made an error and now whenever I search for and try to open or try to directly access two sites which I had tried to access via NetAssistant whilst infected IE8 says they cannot be displayed. One of them is Wikipedia and I use both regularly. I am not sure at what point this happened I think it may have been after using Revo Uninstaller and the second section where it looks for references to netassistant (in the registry?). Not sure if this is relevant but I can remember deleting some flags or something relating to Internet Explorer but not sure what. Any suggestions?

    Hi, I am have random blue screen errors with an error code of bad pool header 0x00000019 whenever I try going online. I use a usb datacard/modem but when I try logging in using a regular dsl/broadband connection, I have the same issue. I had searched the query in windows knowledge base which said it is an issue with windows 7 and have provided a hot fix which they do not gaurentee. My vendor says something is wrong with my ram and has ordered for a new set of ram, but in my opinion if it was a ram related issue, the crashes should have occured even while playing games which are supposed to be ram intensive...If you need the mini dumps I can provide you the same..Kindly revert back..

  • How do I create a Linked Server in SQL Server 2005 to a password protected Access 95 database?

    - by Brad Knowles
    I need to create a linked server with SQL Server Management Studio 2005 to an Access 95 database, which happens to be password protected at the database level. User level security has not been implemented. I cannot convert the Access database to a newer version. It is being used by a 3rd party application; so modifying it, in any way, is not allowed. I've tried using the Jet 4.0 OLE DB Provider and the ODBC OLE DB Provider. The 3rd party application creates a System DSN (with the proper database password), but I've not had any luck in using either method. If I were using a standard connection string, I think it would look something like this: Provider=Microsoft.Jet.OLEDB.4.0;Data Source='C:\Test.mdb';Jet OLEDB:Database Password=####; I'm fairly certain I need to somehow incorporate Jet OLEDB:Database Password into the linked server setup, but haven't figured out how. I've posted the scripts I'm using along with the associated error messages below. Any help is greatly appreciated. I'll provide more details if needed, just ask. Thanks! Method #1 - Using the Jet 4.0 Provider When I try to run these statements to create the linked server: sp_dropserver 'Test', 'droplogins'; EXEC sp_addlinkedserver @server = N'Test', @provider = N'Microsoft.Jet.OLEDB.4.0', @srvproduct = N'Access DB', @datasrc = N'C:\Test.mdb' GO EXEC sp_addlinkedsrvlogin @rmtsrvname=N'Test', @useself=N'False',@locallogin=NULL, @rmtuser=N'Admin', @rmtpassword='####' GO I get this error when testing the connection: TITLE: Microsoft SQL Server Management Studio ------------------------------ "The test connection to the linked server failed." ------------------------------ ADDITIONAL INFORMATION: An exception occurred while executing a Transact-SQL statement or batch.

  • Unable to install Windows Installer 4.5 on Windows Server 2008

    - by Tim Trout
    One of the prerequisites for installing SQL Server 2008 Express R2 is Windows Installer 4.5. I have a couple of WS2008 machines I'm prepping, so I downloaded the appropriate version of the file (Windows6.0-KB942288-v2-x86.msu) to our file server and tried isntalling it on both machines. On both machines I get the cryptic 0x80070003 error: "the system cannot find the file specified", but it does not show which file it cannot find. I don't get this when I try to install the Windows XP version on one of my XP machines. Any clues as to what I might be missing or doing wrong? One Technet help forum suggested I try installing the "System Update Readiness Tool", but this installer also fails for the same error code.

  • Getting macro keys from a razer blackwidow to work on linux

    - by Journeyman Geek
    I picked up a razer blackwidow ultimate that has additional keys meant for macros that are set using a tool that's installed on windows. I'm assuming that these arn't some fancypants joojoo keys and should emit scancodes like any other keys. Firstly is there a standard way to check these scancodes in linux? Secondly how do i set these keys to do things in command line and x based linux setups? My current linux install is xubuntu 10.10, but i'll be switching to kubuntu once i have a few things fixed up. Ideally the answer should be generic and system-wide Things i have tried so far: showkeys from the built in kbd package (in a seperate vt) - macro keys not detected xev - macro keys not detected lsusb and evdev output this ahk script's output suggests the M keys are not outputting standard scancodes Things i need to try snoopy pro + reverse engineering (oh dear) Wireshark - preliminary futzing around seems to indicate no scancodes emitted when what i seem to think is the keyboard is monitored and keys pressed. Might indicate additional keys are a seperate device or need to be initialised somehow. Need to cross reference that with lsusb output from linux, in 3 scenarios - standalone, passed through to a windows VM without the drivers installed, and the same with. LSUSB only detects one device on a standalone linux install It might be useful to check if the mice use the same razer synapse driver , since that means some variation of razercfg might work (not detected. only seems to work for mice) Things i have Have worked out: In a windows system with the driver, the keyboard is seen as a keyboard and a pointing device. And said pointing device uses, in addition to your bog standard mouse drivers.. a driver for something called a razer synapse. Mouse driver seen in linux under evdev and lsusb as well Single Device under OS X apparently, though i have yet to try lsusb equivilent on that Keyboard goes into pulsing backlight mode in OS X upon initialisation with the driver. This should probably indicate that there's some initialisation sequence sent to the keyboard on activation. They are, in fact, fancypants joojoo keys. Extending this question a little I have access to a windows system so if i need to use any tools on that to help answer the question, its fine. I can also try it on systems with and without the config utility. The expected end result is still to make those keys usable on linux however. I also realise this is a very specific family of hardware. I would be willing to test anything that makes sense on a linux system if i have detailed instructions - this should open up the question to people who have linux skills, but no access to this keyboard The minimum end result i require I need these keys detected, and usable in any fashion on any of the current graphical mainstream ubuntu varients

  • Keep getting invalid IP via WiFi

    - by nmuntz
    There is something wrong with my WiFi. I keep getting an invalid IP via DHCP (169.254.x.x), this happens for ALL wifi connections (home, office, etc). If I try a Local Ethernet connection via cable it works fine. I have tried downloading the latest drivers for my wireless adapter, resetting the TCP Stack and still have this issue. One strange thing I notice is under Device Manager, Network Adapters I have 4 "Unknown Devices" and three "Remote NDIS based Internet Sharing Device". My guess is that this belongs to McAfee. Not sure if this is related or not, anyways to try to fix this I tried downloading the NetLUIDfix.exe utility from McAfee but it didn't work. Any ideas how to solve this annoying issue? Thanks!!

  • Firefox 3.5.6 causes entire computer to freeze

    - by Anthony Aziz
    Here's the situation: Environment: Just installed a fresh copy of Win7 Pro 32-bit to NTFS partition on 750GB SATA drive Hardware: E8400 3GHz ASUS P5QL Pro 4GB DDR2 1066 RAM EVGA 9800 GTX+ Plenty of cooling, no problems with hardware before Data is stored on a separate partition, including My Documents No security software is yet installed No extensions installed yet Problem: While using Firefox, sometimes the entire computer will freeze/hang. I get no mouse or keyboard input, can't CTRL+ALT+DEL, no "not responding" indication, just a static image on my display. My drivers are all up to date as far as I'm aware (I just installed this copy of Windows last week). I first noticed this when trying to install Xmarks. I went to the Xmarks site and tried to install and it would freeze. I managed to get it installed (Safe mode and the Mozilla addon site worked), but when I go to configure it (log in, etc), the computer freezes. I don't think it's a matter of usage time or memory issues, because while testing, I browsed wallpaper galleries for about 30 minutes, sometimes as many as 12-15 tabs open at a time, without issue. Sometimes I won't even try to install Xmarks at it will hang. I can install (some) other extensions, the only one I've tried is download status bar (which works). What I've done to try to fix: Restarted (duh) Windows safe mode Completely remove Firefox and install it to a new directory, according to Mozilla's KB (I haven't tried the profile manager, though I assume this does the same thing, except perhaps more thoroughly) Some BIOS changes, including Power options, disabling oveclocking (it was a modest overclock on the CPU, which has run Win7 beta and RC for almost a year now) Memtest Used another Windows user profile, same tragic results I'm STUCK now, with no idea what to do. I'm using Chrome as my main browser at the moment, but that's not something I want to be stuck with. I like Firefox and want to use it. I'm going to try creating a new profile first. One thing I did notice: I started leaving task manager and performance monitor open when anticipating (but dreading) a freeze. firefox.exe had low CPU and low memory, but it looked like overall disk usage was seeing some spikes on the small graph Performance Monitor gives you. I saw on one blog post a fellow using XP moved his Local Settings directory from a separate drive to his main drive, and that solved it, but I don't think my AppData directory is on my D: drive, and that's on the same physical device anyways. Still, something that might be worth trying. I'd extremely appreciate any help. Thanks very much. I really don't want to reinstall Windows from scratch again :( Anthony Aziz

  • Setting alias in Windows PowerShell

    - by westsider
    In PowerShell, I type: PS C: sal cdp "cd 'C:\Users\ec\Documents\Visual Studio 2010\Projects'" I get no error from this, and PS C: gal cdp shows definition as: cd 'C:\Users\ec\Documents\Visual Studio 2010\Projects' But, when I try to use cdp, I get this: Cannot resolve alias 'cdp' because it refers to term 'cd 'C:\Users\ec\Documents\Visual Studio 2010\Projects'', which is not recognized as a cmdlet, function, operable program, or script file. Verify the term and try again. At line:1 char:4 + cdp <<<<  + CatergoryInfo   : ObjectNotFound (dsp:String) [], CommandNotFoundException  + FullyQualifiedErrorId   : AliasNotResolvedException I am guessing that this is trivially easy. So I apologize in advance if that is the case. I have googled and googled and have also read through Windows PowerShell Cookbook.

  • Linux Mint 13 64bit Cinnamon and Oracle Virtualbox: 3d acceleration crash

    - by Stephen Swensen
    I've recently got an interest in Linux. After some research, it looks like Linux Mint 13 cinnamon is hot and I thought I'd try it out... I'm running Windows 7 64bit and have experience with Oracle Virtual Box. So I thought it would be a good idea to try out Linux Mint inside Virtual Box. I download Linux Mint 13 64bit Cinnamon and set it up in my VM player... Nothing special about my settings. Except Linux Mint 13 Cinnamon requires 3d acceleration, and when I enable that, it crashes whenever I open the Menu in the bottom left corner of the guest OS (and some other times too)... I've seen other mentions of this problem on the web, but no solutions. Is there a solution? If not, any suggestions short of installing the OS on a partition for trying out this OS (I'm not interested in the LIve mode either - I'd really like to get the full feel for it)?

  • Testdisk won’t list files for an ext4 partition inside a LVM inside a LUKS partition

    - by user1598585
    I have accidentally deleted a file that I want to recover. The partition is an ext4 partition inside an LVM partition that is encrypted with dm-crypt/LUKS. The encrypted LUKS partition is: /dev/sda2 which contains a physical volume, with a single volume group, mapped to: /dev/mapper/system And the logical volume, the ext4 partition is mapped to: /dev/mapper/system-home A # testdisk /dev/mapper/system-home will notice it as an ext4 partition but tells me that the partition seems damaged when I try to list the files. If I # testdisk /dev/mapper/system it will detect all the partitions, but the same happens if I try to list their files. Am I doing something wrong or is it a known bug?
