• Updating Debian kernel

  - by Devator

  I'm trying to update my Debian machine to 2.6.32-46 (which is the new stable). However, after doing apt-get update my apt-cache search linux-image shows me: linux-headers-2.6.32-5-486 - Header files for Linux 2.6.32-5-486 linux-headers-2.6.32-5-686-bigmem - Header files for Linux 2.6.32-5-686-bigmem linux-headers-2.6.32-5-686 - Header files for Linux 2.6.32-5-686 linux-headers-2.6.32-5-amd64 - Header files for Linux 2.6.32-5-amd64 linux-headers-2.6.32-5-openvz-686 - Header files for Linux 2.6.32-5-openvz-686 linux-headers-2.6.32-5-vserver-686-bigmem - Header files for Linux 2.6.32-5-vser ver-686-bigmem linux-headers-2.6.32-5-vserver-686 - Header files for Linux 2.6.32-5-vserver-686 linux-headers-2.6.32-5-xen-686 - Header files for Linux 2.6.32-5-xen-686 linux-image-2.6.32-5-486 - Linux 2.6.32 for old PCs linux-image-2.6.32-5-686-bigmem-dbg - Debugging infos for Linux 2.6.32-5-686-big mem linux-image-2.6.32-5-686-bigmem - Linux 2.6.32 for PCs with 4GB+ RAM linux-image-2.6.32-5-686 - Linux 2.6.32 for modern PCs linux-image-2.6.32-5-amd64 - Linux 2.6.32 for 64-bit PCs linux-image-2.6.32-5-openvz-686-dbg - Debugging infos for Linux 2.6.32-5-openvz- 686 linux-image-2.6.32-5-openvz-686 - Linux 2.6.32 for modern PCs, OpenVZ support linux-image-2.6.32-5-vserver-686-bigmem-dbg - Debugging infos for Linux 2.6.32-5 -vserver-686-bigmem linux-image-2.6.32-5-vserver-686-bigmem - Linux 2.6.32 for PCs with 4GB+ RAM, Li nux-VServer support linux-image-2.6.32-5-vserver-686 - Linux 2.6.32 for modern PCs, Linux-VServer su pport linux-image-2.6.32-5-xen-686-dbg - Debugging infos for Linux 2.6.32-5-xen-686 linux-image-2.6.32-5-xen-686 - Linux 2.6.32 for modern PCs, Xen dom0 support linux-image-2.6-486 - Linux 2.6 for old PCs (meta-package) linux-image-2.6-686-bigmem - Linux 2.6 for PCs with 4GB+ RAM (meta-package) linux-image-2.6-686 - Linux 2.6 for modern PCs (meta-package) linux-image-2.6-amd64 - Linux 2.6 for 64-bit PCs (meta-package) linux-image-2.6-openvz-686 - Linux 2.6 for modern PCs (meta-package), OpenVZ sup port linux-image-2.6-vserver-686-bigmem - Linux 2.6 for PCs with 4GB+ RAM (meta-packa ge), Linux-VServer support linux-image-2.6-vserver-686 - Linux 2.6 for modern PCs (meta-package), Linux-VSe rver support linux-image-2.6-xen-686 - Linux 2.6 for modern PCs (meta-package), Xen dom0 supp ort linux-image-486 - Linux for old PCs (meta-package) linux-image-686-bigmem - Linux for PCs with 4GB+ RAM (meta-package) linux-image-686 - Linux for modern PCs (meta-package) linux-image-amd64 - Linux for 64-bit PCs (meta-package) linux-image-openvz-686 - Linux for modern PCs (meta-package), OpenVZ support linux-image-vserver-686-bigmem - Linux for PCs with 4GB+ RAM (meta-package), Lin ux-VServer support linux-image-vserver-686 - Linux for modern PCs (meta-package), Linux-VServer sup port linux-image-xen-686 - Linux for modern PCs (meta-package), Xen dom0 support So, 2.6.32-46 doesn't seem to be found.

• PostgreSQL service doesn't start on Windows 7

  - by Mehrdad

  (Not sure if this should be on Stack Overflow or Super User... please move if needed.) When I start the PostgreSQL service on Windows 7 x64, it immediately stops. When I check my log folder (C:\PostgreSQL\9.1\data\pg_log\), I see new but empty log files. The Event Viewer doesn't tell me anything other than the fact that the server did not respond. I've even tried turning off my firewall (I don't have any antivirus or anything else), but nothing helps. The setup works fine when I'm on Windows XP (32-bit) (same computer, different partition). I can't figure out what's wrong, even though I've tried tracing the system calls. Is PostgreSQL compatible with Windows 7 x64 at all? Any ideas what the issue might be? More info: This problem also happens at the end of installation -- the service starts, then stops immediately, before the installer can do anything. Installation log: Starting the database server...

• JMX Based Monitoring - Part Three - Web App Server Monitoring

  - by Anthony Shorten

  In the last blog entry I showed a technique for integrating a JMX console with Oracle WebLogic which is a standard feature of Oracle WebLogic 11g. Customers on other Web Application servers and other versions of Oracle WebLogic can refer to the documentation provided with the server to do a similar thing. In this blog entry I am going to discuss a new feature that is only present in Oracle Utilities Application Framework 4 and above that allows JMX to be used for management and monitoring the Oracle Utilities Web Applications. In this case JMX can be used to perform monitoring as well as provide the management of the cache. In Oracle Utilities Application Framework you can enable Web Application Server JMX monitoring that is unique to the framework by specifying a JMX port number in RMI Port number for JMX Web setting and initial credentials in the JMX Enablement System User ID and JMX Enablement System Password configuration options. These options are available using the configureEnv[.sh] -a utility. Once this is information is supplied a number of configuration files are built (by the initialSetup[.sh] utility) to configure the facility: spl.properties - contains the JMX URL, the security configuration and the mbeans that are enabled. For example, on my demonstration machine: spl.runtime.management.rmi.port=6740 spl.runtime.management.connector.url.default=service:jmx:rmi:///jndi/rmi://localhost:6740/oracle/ouaf/webAppConnector jmx.remote.x.password.file=scripts/ouaf.jmx.password.file jmx.remote.x.access.file=scripts/ouaf.jmx.access.file ouaf.jmx.com.splwg.base.support.management.mbean.JVMInfo=enabled ouaf.jmx.com.splwg.base.web.mbeans.FlushBean=enabled ouaf.jmx.* files - contain the userid and password. The default setup uses the JMX default security configuration. You can use additional security features by altering the spl.properties file manually or using a custom template. For more security options see the JMX Site. Once it has been configured and the changes reflected in the product using the initialSetup[.sh] utility the JMX facility can be used. For illustrative purposes, I will use jconsole but any JSR160 complaint browser or client can be used (with the appropriate configuration). Once you start jconsole (ensure that splenviron[.sh] is executed prior to execution to set the environment variables or for remote connection, ensure java is in your path and jconsole.jar in your classpath) you specify the URL in the spl.management.connnector.url.default entry and the credentials you specified in the jmx.remote.x.* files. Remember these are encrypted by default so if you try and view the file you may be able to decipher it visually. For example: There are three Mbeans available to you: flushBean - This is a JMX replacement for the jsp versions of the flush utilities provided in previous releases of the Oracle Utilities Application Framework. You can manage the cache using the provided operations from JMX. The jsp versions of the flush utilities are still provided, for backward compatibility, but now are authorization controlled. JVMInfo - This is a JMX replacement for the jsp version of the JVMInfo screen used by support to get a handle on JVM information. This information is environmental not operational and is used for support purposes. The jsp versions of the JVMInfo utilities are still provided, for backward compatibility, but now is also authorization controlled. JVMSystem - This is an implementation of the Java system MXBeans for use in monitoring. We provide our own implementation of the base Mbeans to save on creating another JMX configuration for internal monitoring and to provide a consistent interface across platforms for the MXBeans. This Mbean is disabled by default and can be enabled using the enableJVMSystemBeans operation. This Mbean allows for the monitoring of the ClassLoading, Memory, OperatingSystem, Runtime and the Thread MX beans. Refer to the Server Administration Guides provided with your product and the Technical Best Practices Whitepaper for information about individual statistics. The Web Application Server JMX monitoring allows greater visibility for monitoring and management of the Oracle Utilities Application Framework application from jconsole or any JSR160 compliant JMX browser or JMX console.

• How to get Ruby support in Zend Studio?

  - by Andrew

  Zend Studio is basically Eclipse that has been optimized for working with Zend Framework projects. Well I have a few files in my Zend Framework project that happen to be Ruby files. Zend Studio doesn't come with the ability to create/edit Ruby files with syntax highlighting. I could open in the default text editor, but there won't be any syntax highlighting. How can I add support for Ruby files in Zend Studio?

• extension-base file associations

  - by Maurice Perry

  Hi there, I am using ubuntu 9.10, and I would like to associate thunderbird to all the files with the extension .eml. The problem is that is seems that ubuntu is attributing the mime type text/plain to these files, based on their content, which meens that if I set thunderbird as the default application for .eml files, all the other text files (.txt for instance) will be opened with thunderbird. Is it possible to add a rule to impose a mime type based on the file extension, regardless of its content?

• Detecting upload success/failure in a scripted command-line SFTP session?

  - by Will Martin

  I am writing a BASH shell script to upload all the files in a directory to a remote server and then delete them. It'll run every few hours via a CRON job. My complete script is below. The basic problem is that the part that's supposed to figure out whether the file uploaded successfully or not doesn't work. The SFTP command's exit status is always "0" regardless of whether the upload actually succeeded or not. How can I figure out whether a file uploaded correctly or not so that I can know whether to delete it or let it be? #!/bin/bash # First, save the folder path containing the files. FILES=/home/bob/theses/* # Initialize a blank variable to hold messages. MESSAGES="" ERRORS="" # These are for notifications of file totals. COUNT=0 ERRORCOUNT=0 # Loop through the files. for f in $FILES do # Get the base filename BASE=`basename $f` # Build the SFTP command. Note space in folder name. CMD='cd "Destination Folder"\n' CMD="${CMD}put ${f}\nquit\n" # Execute it. echo -e $CMD | sftp -oIdentityFile /home/bob/.ssh/id_rsa [email protected] # On success, make a note, then delete the local copy of the file. if [ $? == "0" ]; then MESSAGES="${MESSAGES}\tNew file: ${BASE}\n" (( COUNT=$COUNT+1 )) # Next line commented out for ease of testing #rm $f fi # On failure, add an error message. if [ $? != "0" ]; then ERRORS="${ERRORS}\tFailed to upload file ${BASE}\n" (( ERRORCOUNT=$ERRORCOUNT+1 )) fi done SUBJECT="New Theses" BODY="There were ${COUNT} files and ${ERRORCOUNT} errors in the latest batch.\n\n" if [ "$MESSAGES" != "" ]; then BODY="${BODY}New files:\n\n${MESSAGES}\n\n" fi if [ "$ERRORS" != "" ]; then BODY="${BODY}Problem files:\n\n${ERRORS}" fi # Send a notification. echo -e $BODY | mail -s $SUBJECT [email protected] Due to some operational considerations that make my head hurt, I cannot use SCP. The remote server is using WinSSHD on windows, and does not have EXEC privileges, so any SCP commands fail with the message "Exec request failed on channel 0". The uploading therefore has to be done via the interactive SFTP command.

• smb mount cannot sync file automatically

  - by Frank

  Under Ubuntu, I use smb to mount the directory of the server(Ubuntu too), and set to a local directory, like /home/username/server. When I change some files of local directory, the files in the server change too. However, when I change some files of the server, the files in local directory don't change. Does someone know what the reason is ? And could someone fix it and make local changes updated to the server so that I could edit local and make in the server?

• How to set the default language in Notepad++

  - by AngryHacker

  I mostly use Notepad++ for dealing with XML files. It would be good if Notepad++ parsed and colorized my files based on the XML language when I open the files. Instead, I have to open the file, pick XML from the Languages menu. Is there a way to tell Notepad++ that XML is the default language and to treat the files accordingly.

  I've brought Vista Ultimate DVD from my friend, there was a .iso file. I extracted them and found two files(there was some boot files too) : boot.wim install.wim I extracted the boot.wim with WinMount. But I can't extracting the install.wim Should I Burn the whole files(extracted and past files) into a DVD Or, Should I try to extract the install.wim ???? I searched Google, some forums and websites said that the setup.exe can extract the install.wim before starting the Installation.(I found the setup.exe after extracting the boot.wim)

• WSS having two OWSTIMER.EXE (v11 and v12) running at the same time

  - by Nelson Reis

  I've just found that my WSS 3.0 server had two OWSTIMER.EXE services running: SharePoint Timer Service v11 "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\60\BIN\OWSTIMER.EXE" Windows SharePoint Services Timer v12 "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\BIN\OWSTIMER.EXE" Since I'm running WSS v3, I was expecting to have only one SharePoint Timer instance, and that should be the one in th "12" folder. Should I just stop the other service and keep only the "Windows SharePoint Services Timer" (v12) running?

• Improving WIF&rsquo;s Claims-based Authorization - Part 1

  - by Your DisplayName here!

  As mentioned in my last post, I made several additions to WIF’s built-in authorization infrastructure to make it more flexible and easy to use. The foundation for all this work is that you have to be able to directly call the registered ClaimsAuthorizationManager. The following snippet is the universal way to get to the WIF configuration that is currently in effect: public static ServiceConfiguration ServiceConfiguration {     get     {         if (OperationContext.Current == null)         {             // no WCF             return FederatedAuthentication.ServiceConfiguration;         }         // search message property         if (OperationContext.Current.IncomingMessageProperties. ContainsKey("ServiceConfiguration"))         {             var configuration = OperationContext.Current. IncomingMessageProperties["ServiceConfiguration"] as ServiceConfiguration;             if (configuration != null)             {                 return configuration;             }         }         // return configuration from configuration file         return new ServiceConfiguration();     } }   From here you can grab ServiceConfiguration.ClaimsAuthoriationManager which give you direct access to the CheckAccess method (and thus control over claim types and values). I then created the following wrapper methods: public static bool CheckAccess(string resource, string action) {     return CheckAccess(resource, action, Thread.CurrentPrincipal as IClaimsPrincipal); } public static bool CheckAccess(string resource, string action, IClaimsPrincipal principal) {     var context = new AuthorizationContext(principal, resource, action);     return AuthorizationManager.CheckAccess(context); } public static bool CheckAccess(Collection<Claim> actions, Collection<Claim> resources) {     return CheckAccess(new AuthorizationContext(         Thread.CurrentPrincipal.AsClaimsPrincipal(), resources, actions)); } public static bool CheckAccess(AuthorizationContext context) {     return AuthorizationManager.CheckAccess(context); } I also created the same set of methods but called DemandAccess. They internally use CheckAccess and will throw a SecurityException when false is returned. All the code is part of Thinktecture.IdentityModel on Codeplex – or via NuGet (Install-Package Thinktecture.IdentityModel).

• ORA-4031 Troubleshooting

  - by [email protected]

    QUICKLINK: Note 396940.1 Troubleshooting and Diagnosing ORA-4031 Error Note 1087773.1 : ORA-4031 Diagnostics Tools [Video]   Have you observed an ORA-04031 error reported in your alert log? An ORA-4031 error is raised when memory is unavailable for use or reuse in the System Global Area (SGA).  The error message will indicate the memory pool getting errors and high level information about what kind of allocation failed and how much memory was unavailable.  The challenge with ORA-4031 analysis is that the error and associated trace is for a "victim" of the problem.   The failing code ran into the memory limitation, but in almost all cases it was not part of the root problem.    Looking for the best way to diagnose? When an ORA-4031 error occurs, a trace file is raised and noted in the alert log if the process experiencing the error is a background process.   User processes may experience errors without reports in the alert log or traces generated.   The V$SHARED_POOL_RESERVED view will show reports of misses for memory over the life of the database. Diagnostics scripts are available in Note 430473.1 to help in analysis of the problem.  There is also a training video on using and interpreting the script data Note 1087773.1. 11g DiagnosabilityStarting with Oracle Database 11g Release 1, the Diagnosability infrastructure was introduced which places traces and core files into a location controlled by the DIAGNOSTIC_DEST initialization parameter when an incident, such as an ORA-4031 occurs. For earlier versions, the trace file will be written to either USER_DUMP_DEST (if the error was caught in a user process) or BACKGROUND_DUMP_DEST (if the error was caught in a background process like PMON or SMON). The trace file contains vital information about what led to the error condition.  Note 443529.1 11g Quick Steps to Package and Send Critical Error Diagnostic Information to Support[Video]Oracle Configuration Manager (OCM)Oracle Configuration Manager (OCM) works with My Oracle Support to enable proactive support capability that helps you organize, collect and manage your Oracle configurations.Oracle Configuration Manager Quick Start GuideNote 548815.1: My Oracle Support Configuration Management FAQ Note 250434.1: BULLETIN: Learn More About My Oracle Support Configuration Manager    Common Causes/Solutions The ORA-4031 can occur for many different reasons.  Some possible causes are: SGA components too small for workload Auto-tuning issues Fragmentation due to application design Bug/leaks in memory allocationsFor more on the 4031 and how this affects the SGA, see Note 396940.1 Troubleshooting and Diagnosing ORA-4031 Error Because of the multiple potential causes, it is important to gather enough diagnostics so that an appropriate solution can be identified.  However, most commonly the cause is associated with configuration tuning.   Ensuring that MEMORY_TARGET or SGA_TARGET are large enough to accommodate workload can get around many scenarios.  The default trace associated with the error provides very high level information about the memory problem and the "victim" that ran into the issue.   The data in the default trace is not going to point to the root cause of the problem. When migrating from 9i to 10g and higher, it is necessary to increase the size of the Shared Pool due to changes in the basic design of the shared memory area. Note 270935.1 Shared pool sizing in 10gNOTE: Diagnostics on the errors should be investigated as close to the time of the error(s) as possible.  If you must restart a database, it is not feasible to diagnose the problem until the database has matured and/or started seeing the problems again. Note 801787.1 Common Cause for ORA-4031 in 10gR2, Excess "KGH: NO ACCESS" Memory Allocation ***For reference to the content in this blog, refer to Note.1088239.1 Master Note for Diagnosing ORA-4031

• How to get full control of umask/PAM/permissions?

  - by plua

  OUR SITUATION Several people from our company log in to a server and upload files. They all need to be able to upload and overwrite the same files. They have different usernames, but are all part of the same group. However, this is an internet server, so the "other" users should have (in general) just read-only access. So what I want to have is these standard permissions: files: 664 directories: 771 My goal is that all users do not need to worry about permissions. The server should be configured in such a way that these permissions apply to all files and directories, newly created, copied, or over-written. Only when we need some special permissions we'd manually change this. We upload files to the server by SFTP-ing in Nautilus, by mounting the server using sshfs and accessing it in Nautilus as if it were a local folder, and by SCP-ing in the command line. That basically covers our situation and what we aim to do. Now, I have read many things about the beautiful umask functionality. From what I understand umask (together with PAM) should allow me to do exactly what I want: set standard permissions for new files and directories. However, after many many hours of reading and trial-and-error, I still do not get this to work. I get many unexpected results. I really like to get a solid grasp of umask and have many question unanswered. I will post these questions below, together with my findings and an explanation of my trials that led to these questions. Given that many things appear to go wrong, I think that I am doing several things wrong. So therefore, there are many questions. NOTE: I am using Ubuntu 9.10 and therefore can not change the sshd_config to set the umask for the SFTP server. Installed SSH OpenSSH_5.1p1 Debian-6ubuntu2 < required OpenSSH 5.4p1. So here go the questions. 1. DO I NEED TO RESTART FOR PAM CHANGS TO TAKE EFFECT? Let's start with this. There were so many files involved and I was unable to figure out what does and what does not affect things, also because I did not know whether or not I have to restart the whole system for PAM changes to take effect. I did do so after not seeing the expected results, but is this really necessary? Or can I just log out from the server and log back in, and should new PAM policies be effective? Or is there some 'PAM' program to reload? 2. IS THERE ONE SINGLE FILE TO CHANGE THAT AFFECTS ALL USERS FOR ALL SESSIONS? So I ended up changing MANY files, as I read MANY different things. I ended up setting the umask in the following files: ~/.profile -> umask=0002 ~/.bashrc -> umask=0002 /etc/profile -> umask=0002 /etc/pam.d/common-session -> umask=0002 /etc/pam.d/sshd -> umask=0002 /etc/pam.d/login -> umask=0002 I want this change to apply to all users, so some sort of system-wide change would be best. Can it be achieved? 3. AFTER ALL, THIS UMASK THING, DOES IT WORK? So after changing umask to 0002 at every possible place, I run tests. ------------SCP----------- TEST 1: scp testfile (which has 777 permissions for testing purposes) server:/home/ testfile 100% 4 0.0KB/s 00:00 Let's check permissions: user@server:/home$ ls -l total 4 -rwx--x--x 1 user uploaders 4 2011-02-05 17:59 testfile (711) ---------SSH------------ TEST 2: ssh server user@server:/home$ touch anotherfile user@server:/home$ ls -l total 4 -rw-rw-r-- 1 user uploaders 0 2011-02-05 18:03 anotherfile (664) --------SFTP----------- Nautilus: sftp://server/home/ Copy and paste newfile from client to server (777 on client) TEST 3: user@server:/home$ ls -l total 4 -rwxrwxrwx 1 user uploaders 3 2011-02-05 18:05 newfile (777) Create a new file through Nautilus. Check file permissions in terminal: TEST 4: user@server:/home$ ls -l total 4 -rw------- 1 user uploaders 0 2011-02-05 18:06 newfile (600) I mean... WHAT just happened here?! We should get 644 every single time. Instead I get 711, 777, 600, and then once 644. And the 644 is only achieved when creating a new, blank file through SSH, which is the least probable scenario. So I am asking, does umask/pam work after all? 4. SO WHAT DOES IT MEAN TO UMASK SSHFS? Sometimes we mount a server locally, using sshfs. Very useful. But again, we have permissions issues. Here is how we mount: sshfs -o idmap=user -o umask=0113 user@server:/home/ /mnt NOTE: we use umask = 113 because apparently, sshfs starts from 777 instead of 666, so with 113 we get 664 which is the desired file permission. But what now happens is that we see all files and directories as if they are 664. We browse in Nautilus to /mnt and: Right click - New File (newfile) --- TEST 5 Right click - New Folder (newfolder) --- TEST 6 Copy and paste a 777 file from our local client --- TEST 7 So let's check on the command line: user@client:/mnt$ ls -l total 8 -rw-rw-r-- 1 user 1007 3 Feb 5 18:05 copyfile (664) -rw-rw-r-- 1 user 1007 0 Feb 5 18:15 newfile (664) drw-rw-r-- 1 user 1007 4096 Feb 5 18:15 newfolder (664) But hey, let's check this same folder on the server-side: user@server:/home$ ls -l total 8 -rwxrwxrwx 1 user uploaders 3 2011-02-05 18:05 copyfile (777) -rw------- 1 user uploaders 0 2011-02-05 18:15 newfile (600) drwx--x--x 2 user uploaders 4096 2011-02-05 18:15 newfolder (711) What?! The REAL file permissions are very different from what we see in Nautilus. So does this umask on sshfs just create a 'filter' that shows unreal file permissions? And I tried to open a file from another user but the same group that had real 600 permissions but 644 'fake' permissions, and I could still not read this, so what good is this filter?? 5. UMASK IS ALL ABOUT FILES. BUT WHAT ABOUT DIRECTORIES? From my tests I can see that the umask that is being applied also somehow influences the directory permissions. However, I want my files to be 664 (002) and my directories to be 771 (006). So is it possible to have a different umask for directories? 6. PERHAPS UMASK/PAM IS REALLY COOL, BUT UBUNTU IS JUST BUGGY? On the one hand, I have read topics of people that have had success with PAM/UMASK and Ubuntu. On the other hand, I have found many older and newer bugs regarding umask/PAM/fuse on Ubuntu: https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/241198 https://bugs.launchpad.net/ubuntu/+source/fuse/+bug/239792 https://bugs.launchpad.net/ubuntu/+source/pam/+bug/253096 https://bugs.launchpad.net/ubuntu/+source/sudo/+bug/549172 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=314796 So I do not know what to believe anymore. Should I just give up? Would ACL solve all my problems? Or do I have again problems using Ubuntu? One word of caution with backups using tar. Red Hat /Centos distributions support acls in the tar program but Ubuntu does not support acls when backing up. This means that all acls will be lost when you create a backup. I am very willing to upgrade to Ubuntu 10.04 if that would solve my problems too, but first I want to understand what is happening.

• how to strip string from url using rewrite rule

  sometimes my drupal site add extra string to image url which causes the image to be broken. the url is http://mysite.com/sites/default/files/imagecache/list_image_page/%252Fsites/default/files/img.jpg what is the needed rewrite rule to strip the bolded (%252F) part in the above link ie. to be: http://mysite.com/sites/default/files/imagecache/list_image_page/sites/default/files/img.jpg I have tried this, but didn't work RewriteCond %{QUERY_STRING} ^(.*)\%252Fsites(.*)$ RewriteRule %{REQUEST_URI} %1sites%2

• Easy Made Easier - Networking

  - by dragonfly

      In my last post, I highlighted the feature of the Appliance Manager Configurator to auto-fill some fields based on previous field values, including host names based on System Name and sequential IP addresses from the first IP address entered. This can make configuration a little faster and a little less subject to data entry errors, particularly if you are doing the configuration on the Oracle Database Appliance itself.     The Oracle Database Appliance Appliance Manager Configurator is available for download here. But why would you download it, if it comes pre-installed on the Oracle Database Appliance? A common reason for customers interested in this new Engineered System is to get a good idea of how easy it is to configure. Beyond that, you can save the resulting configuration as a file, and use it on an Oracle Database Appliance. This allows you to verify the data entered in advance, and in the comfort of your office. In addition, the topic of this post is another strong reason to download and use the Appliance Manager Configurator prior to deploying your Oracle Database Appliance.     The most common source of hiccups in deploying an Oracle Database Appliance, based on my experiences with a variety of customers, involves the network configuration. It is during Step 11, when network validation occurs, that these come to light, which is almost half way through the 24 total steps, and can be frustrating, whether it was a typo, DNS mis-configuration or IP address already in use. This is why I recommend as a best practice taking advantage of the Appliance Manager Configurator prior to deploying an Oracle Database Appliance.     Why? Not only do you get the benefit of being able to double check your entries before you even start on the Oracle Database Appliance, you can also take advantage of the Network Validation step. This is the final step before you review all the data and can save it to a text file. It can be skipped, if you aren't ready or are not connected to the network that the Oracle Database Appliance will be on. My recommendation, though, is to run the Appliance Manager Configurator on your laptop, enter the data or re-load a previously saved file of the data, and then connect to the network that the Oracle Database Appliance will be on. Now run the Network Validation. It will check to make sure that the host names you entered are in DNS and do resolve to the IP addresses you specifiied. It will also ping the IP Addresses you specified, so that you can verify that no other machine is already using them (yes, that has happened at customer sites).     After you have completed the validation, as seen in the screen shot below, you can review the results and move on to saving your settings to a file for use on your Oracle Database Appliance, or if there are errors, you can use the Back button to return to the appropriate screen and correct the data. Once you are satisfied with the Network Validation, just check the Skip/Ignore Network Validation checkbox at the top of the screen, then click Next. Is the Network Validation in the Appliance Manager Configurator required? No, but it can save you time later. I should also note that the Network Validation screen is not part of the Appliance Manager Configurator that currently ships on the Oracle Database Appliance, so this is the easiest way to verify your network configuration.     I hope you are finding this series of posts useful. My next post will cover some aspects of the windowing environment that gets run by the 'startx' command on the Oracle Database Appliance, since this is needed to run the Appliance Manager Configurator via a direct connected monitor, keyboard and mouse, or via the ILOM. If it's been a while since you've used an OpenWindows environment, you'll want to check it out.

• Setup and configure a MVC4 project for Cloud Service(web role) and SQL Azure

  - by MagnusKarlsson

  I aim at keeping this blog post updated and add related posts to it. Since there are a lot of these out there I link to others that has done kind of the same before me, kind of a blog-DRY pattern that I'm aiming for. I also keep all mistakes and misconceptions for others to see. As an example; if I hit a stacktrace I will google it if I don't directly figure out the reason for it. I will then probably take the most plausible result and try it out. If it fails because I misinterpreted the error I will not delete it from the log but keep it for future reference and for others to see. That way people that finds this blog can see multiple solutions for indexed stacktraces and I can better remember how to do stuff. To avoid my errors I recommend you to read through it all before going from start to finish.The steps:Setup project in VS2012.

• Is there a way to combine multiple TextMate windows?

  - by yahelc

  After files have already been opened in separate windows, is there a way to combine them in TextMate 1.5.9? Or, is there a way to get CyberDuck to open group files edited at the same time as TextMate projects? If you open a folder of files in TextMate, it groups them all in one window like such: But, if I open multiple files separately (as my FTP forces), they appear in multiple windows. Is there any way to combine multiple TextMate windows into one, so they appear grouped like in the screenshot above?

• Why Photoshop CS5's photomerge's result immediately disappear?

  - by koiyu

  I have a bunch of JPG-files which I want to stitch together with Photoshop's Photomerge function. I choose File → Automate → Photomerge... and browse for the files. Photoshop opens the files and starts analyzing. I see the process bar filling and different phases are mentioned on the process bar. Nothing weird there. When the merging is done (and if I don't blink my eyes), I can see layers-palette is populated with the chosen files and, by quickly judging from the layer thumbnails, they're properly aligned. Sometimes the image window itself can be seen, but not always. Problem is that the layers and the image disappear in a flash. There is no error message. Everything is like prior starting the photomerge. No file has been changed. I could continue to use Photoshop normally. This is what I've tried so far: Loaded folder which has 38 JPG images, 4272 x 2848 and ˜ 5 megabytes per file Loaded the same files, but chose Use Files instead of Use Folder in the photomerge's window Loaded 19 JPG images, 4272 x 2848 and ˜ 5 megabytes per file Loaded 10 JPG images, ⇑ see above Loaded 5 JPG images, see above Loaded 3 JPG images, see above Scaled the images to 2256 x 1504 and ˜< 1 megabytes per file Loaded in a set of 38, 19, 10, 5, 3 Following steps are tested with these smaller files and with a set of 5 images Read Adobe's forums and reduced the amount of RAM Photoshop uses gradually from ˜ 80 % to 50 % (though I didn't understand the logic behind this) Would've reduced cache tile size to 128K, but it was set so already Disabled OpenGL Scaled the images to 800 x 533 and ˜ 100 kilobytes per file, loaded a set of 5 Read more unanswered threads around the internet In between each test I closed and reopened Photoshop. This is the first time I've even tried using photomerge. Am I doing something wrong? How can I locate what is the problem? How do I fix this? Photoshop is 64 bit Extended CS5 version. I'm on a mid-2010 quad-core (i5) iMac with up-to-date Mac OS X 10.6.6. Edit: Weird. First loading the images into one file via File → Scripts → Load Files into Stack… and then using Edit → Auto-Align Layers…, which, effectively, is the same as photomerge (even the dialog looks kind of the same), works! Even with the original JPGs without any issues. This doesn't fix photomerge, though.

• Does anybody knows a replacement for TorrentSpy?

  - by Ither

  Hi, I've used TorrentSpy since 2004 and it does a pretty good job but it is very slow with torrent files that have hundreds or thousands of files. Does anyboy knows a better tool for the same job in XP? If you didn't know it, TorrentSpy show the data contained in a torrent file in a readable way: URL's tracker, number of files, its size, number of complete and incomplete downloaders, etc. Edit: What I want is something that can be used from explorer right-clicking in the torrent file, like MediaInfo does with media files.

• How does RSYNC does incremental Backups

  How does RSYNC knows which files are chnages and which are not. Does it logs its data anywhere in the file. Because I want to do incrrmental backups but first it will transfer all files.
