  • Can someone explain an Enterprise Service Bus to me in non-buzzspeak?

    - by Jason Baker
    Some of our partners are telling us that our software needs to interact with an Enterprise Service Bus. After researching this a bit, my instinct is to say that this is just buzz speak for saying that we need to have a platform-indpendent way to pass messages back and forth. I'm just trying to get a feel for what our partners are telling us. Am I correct in dismissing our partners' request as just trying to get our software to be more buzzword-compliant, or are they telling us something we should listen to (even if encoded in buzzspeak)?

  • Enterprise Library Validation Block - Should validation be placed on class or interface?

    - by Robert MacLean
    I am not sure where the best place to put validation (using the Enterprise Library Validation Block) is? Should it be on the class or on the interface? Things that may effect it Validation rules would not be changed in classes which inherit from the interface. Validation rules would not be changed in classes which inherit from the class. Inheritance will occur from the class in most cases - I suspect some fringe cases to inherit from the interface (but I would try and avoid it). The interface main use is for DI which will be done with the Unity block.

  • Django 1.4.1 error loading MySQLdb module when attempting 'python manage.py shell'

    I am trying to set up MySQL, and can't seem to be able to enter the Django manage.py shell interpreter.

  • Can't manage iPod from linux anymore

    I used to be able to see and manage my iPod with different softwares: Amarok, Rhythmbox, GTKPod. The device is a nano 1st generation 4gb. Currently it mounts regularly and can be accessed from the file system, but I get this in dmesg: [ 1547.617891] scsi 11:0:0:0: Direct-Access Apple iPod 1.62 PQ: 0 ANSI: 0 [ 1547.619103] sd 11:0:0:0: Attached scsi generic sg2 type 0 [ 1547.620478] sd 11:0:0:0: [sdb] Adjusting the sector count from its reported value: 7999488 [ 1547.620494] sd 11:0:0:0: [sdb] 7999487 512-byte hardware sectors: (4.09 GB/3.81 GiB) [ 1547.621718] sd 11:0:0:0: [sdb] Write Protect is off [ 1547.621726] sd 11:0:0:0: [sdb] Mode Sense: 68 00 00 08 [ 1547.621732] sd 11:0:0:0: [sdb] Assuming drive cache: write through [ 1547.623591] sd 11:0:0:0: [sdb] Adjusting the sector count from its reported value: 7999488 [ 1547.624993] sd 11:0:0:0: [sdb] Assuming drive cache: write through [ 1547.625003] sdb: sdb1 sdb2 [ 1547.629686] sd 11:0:0:0: [sdb] Attached SCSI removable disk [ 1548.084026] FAT: utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!

Haven't been using my iPod for a while so I can't say when exactly it stopped working. I'm sure Amarok was still at version 1.X but can't remember when it was. My current system is debian testing fully updated. NOTE: just noticed that if I mount the device manually instead of letting nautilus automount it, I can see it again on GTKPod but still not on Banshee AND it's vanished from Rhythmbox...

  • How to add event receiver to SharePoint2010 content type programmatically

    - by ybbest
    Today , I’d like to show how to add event receiver to How to add event receiver to SharePoint2010 content type programmatically. 1. Create empty SharePoint Project and add a class called ItemContentTypeEventReceiver and make it inherit from SPItemEventReceiver and implement your logic as below public class ItemContentTypeEventReceiver : SPItemEventReceiver { private bool eventFiringEnabledStatus; public override void ItemAdded(SPItemEventProperties properties) { base.ItemAdded(properties); UpdateTitle(properties); } private void UpdateTitle(SPItemEventProperties properties) { SPListItem addedItem = properties.ListItem; string enteredTitle = addedItem["Title"] as string; addedItem["Title"] = enteredTitle + " Updated"; DisableItemEventsScope(); addedItem.Update(); EnableItemEventsScope(); } public override void ItemUpdated(SPItemEventProperties properties) { base.ItemUpdated(properties); UpdateTitle(properties); } private void DisableItemEventsScope() { eventFiringEnabledStatus = EventFiringEnabled; EventFiringEnabled = false; } private void EnableItemEventsScope() { eventFiringEnabledStatus = EventFiringEnabled; EventFiringEnabled = true; } } 2.Create a Site or Web(depending or your requirements) scoped feature and implement your feature event handler as below: public override void FeatureActivated(SPFeatureReceiverProperties properties) { SPWeb web = GetFeatureWeb(properties); //http://karinebosch.wordpress.com/walkthroughs/event-receivers-theory/ string assemblyName =  System.Reflection.Assembly.GetExecutingAssembly().FullName; const string className = "YBBEST.AddEventReceiverToContentType.ItemContentTypeEventReceiver"; SPContentType contentType= web.ContentTypes["Item"]; AddEventReceiverToContentType(className, contentType, assemblyName, SPEventReceiverType.ItemAdded, SPEventReceiverSynchronization.Asynchronous); AddEventReceiverToContentType(className, contentType, assemblyName, SPEventReceiverType.ItemUpdated, SPEventReceiverSynchronization.Asynchronous); contentType.Update(); } protected static void AddEventReceiverToContentType(string className, SPContentType contentType, string assemblyName, SPEventReceiverType eventReceiverType, SPEventReceiverSynchronization eventReceiverSynchronization) { if (className == null) throw new ArgumentNullException("className"); if (contentType == null) throw new ArgumentNullException("contentType"); if (assemblyName == null) throw new ArgumentNullException("assemblyName"); SPEventReceiverDefinition eventReceiver = contentType.EventReceivers.Add(); eventReceiver.Synchronization = eventReceiverSynchronization; eventReceiver.Type = eventReceiverType; eventReceiver.Assembly = assemblyName; eventReceiver.Class = className; eventReceiver.Update(); } 3.Deploy your solution and now you have a event receiver that attached to the Item contentType. You can download the complete source code here.You can also check how to add event receiver to a list using SharePoint event receiver item in Visual Studio2010 in my previous blog.

  • Site Studio Mobile Example - WCM Reuse

    - by john.brunswick
    Mobile internet usage is growing by leaps and bounds and it is theorized that in the not-to-distant future it will eclipse traditional access via desktop browsers. Mary Meeker, a managing director at Morgan Stanley and head of their global technology research team, recently predicted that mobile usage will eclipse desktop usage within the next 5 years in an Events@Google series presentation. In order for organizations to reach their prospects, customers and business partners, they will need to make their content readily available on mobile devices. A few years ago it was fairly challenging to provide a special, separate, site to cater to mobile users using technologies like WML (Wireless Markup Language). Modern mobile browsers have rendered the need for this as irrelevant and now the focus has moved toward providing a browsing experience that works well on small screen sizes and is highly performant. What does all of this mean for Oracle UCM? Taking site content from an existing Site Studio site and targeting it for consumption for mobile devices is a very straightforward process that is aided by a number of native capabilities in the product. The example highlighted in this post takes advantage of dynamic conversion capabilities in Oracle UCM to enable site content to be created and updated via MS Office documents. These documents are then converted to a simple, clean HTML format for consumption in the desktop and mobile browsing experiences. To help better understand how this is possible the example below shows a fictional .COM and its mobile site counterpart that both leverage the same underlying content. The scenario is not complete or production ready, but highlights that a mobile experience may be best delivered by omitting portions of a site that would be present within the version served to desktop clients. If you have browsed CNet (news.com) on a mobile device it becomes quickly apparent that they are serving an optimized version for your mobile device. An iPhone style version can be accessed at http://iphone.cnet.com/. In order to do that they leveraged some work done for the iPhone iUi project developed by Joe Hewitt that provides mobile browsers an experience that is similar to what users may find in a native iPhone application. For our example parts of this framework are used (the CSS) and this approach provides a page that will degrade nicely over a wide range of mobile browsers, since it is comprised of lightweight HTML markup and CSS. The iPhone iUi framework also provides some nice JavaScript to enable animated transitions between pages, but for the widest range of mobile browser compatibility we will only incorporate the CSS and HTML DIV / UL based page markup in our example.

  • Maintaining Revision Levels

    - by kyle.hatlestad
    A question that came up on an earlier blog post was how to limit the number of revisions on a piece of content. UCM does not inherently enforce any sort of limit on how many revisions you can have. It's unlimited. In some cases, there may be content that goes through lots of changes, but there just simply isn't a need to keep all of its revisions around. Deleting those revisions through the content information screen can be very cumbersome. And going through the Repository Manager applet can take time as well to filter and find the revisions to get rid of. But there is an easier way through the Archiver. The Export Query criteria in Archiver includes a very handy field called 'Revision Rank'. With revision labels, they typically go up as new revisions come in (e.g. 1, 2, 3, 4, etc...). But you can't really use this field to tell it to keep the top 5 revisions. Those top 5 revision numbers are always going up. But revision rank goes the opposite direction. The very latest revision is always 0. The previous revision to that is 1. Previous revision to that is 2. And so on and so forth. With revision rank, you can set your query to look for any Revision Rank greater or equal to 5. Now as older revisions move down the line, their revision rank gets higher and higher until they reach that threshold. Then when you run that archive export, you can choose to delete and remove those revisions. Running that export in Archiver is normally a manual process. But with Idc Command, you can script the process and have it run automatically from the server. Idc Command is a utility that allows you to run any of the content server services via the command line. You basically feed it a text file with the services and parameters defined along with the user to run it as. The Idc Command executable is located within the \bin\ directory: $ ./IdcCommand -f DeleteOlderRevisions.txt -u sysadmin -l delete_revisions.log In this example, our IdcCommand file to run the export and do the deletions would look like: IdcService=EXPORT_ARCHIVE aArchiveName=DeleteOlderRevisions aDoDelete=1 IDC_Name=idc dataSource=RevisionIDs <<EOD>> You can then use automated scheduling routines in the OS to run the command and command file at the frequency needed. Remember that you are deleting the revisions from within UCM, but they are still getting placed within the archive. So you will need to delete those batches to have them fully removed (or re-import if you need to recover them). For more information about Idc Command, you can find that in the Idc Command Reference Guide.

  • Loading SpriteFont through a different class than Game.cs

    - by MintyAnt
    I am trying to load up a single SpriteFont to print some debug information. In our current game, we load up both Textures and Music through a ResourceManager. They are both loaded with a filestream, and thus do not require Content.Load SoundEffect soundEffect = SoundEffect.FromStream( fs ); Since this ResourceManager does not inherit from Game or is like Game.cs, I cannot use the usual method: SpriteFont spriteFont = Content.Load<SpriteFont>(resource.Key.Item2); Anyone have any idea how I can either: -Load the SpriteFont a different way -Create my own Contentmanager

  • Oracle Tutor: Create Accessible Content for the Disabled Community

    - by emily.chorba(at)oracle.com
    For many reasons--legal, business, and ethical--Oracle recognizes the need for its applications, and our customers' and partners' products built with our tools, to be usable by the disabled community. The following features of Tutor Author and Publisher software facilitate the creation of accessible HTML content for the disabled community.TablesThe following formatting guidelines will ensure that Tutor documents containing tables will be accessible once they are converted to HTML.• Determine whether a table is a "data table" or whether you are using a table simply for formatting. If it's a data table, you must use a heading for each column, and you should format this heading row as "table heading" style and select Table > Heading Rows Repeat.• For non data tables, it is not necessary to include a heading row.GraphicsTo create accessible graphics, add a caption to the graphic. In Microsoft Office 2000 and greater, right-click on the graphic and select Format Picture > Web (tab) > Alternative Text or select the graphic then Format > Picture > Web (tab) Alternative Text. Enter the appropriate information in the dialog box.When a document containing a graphic with alternative text is converted to HTML by Tutor, the HTML document will contain the appropriate accessibility information.Javascript elementsThe tabbed format and other javascript elements in the HTML version of the Tutor documents may not be accessible to all users. A link to an accessible/printable version of the document is available in the upper right corner of all Tutor documents.Repetitive dataIf repetitive data such as the distribution section and the ownership section are causing accessibility issues with your Tutor documents, you can insert a bookmark in the appropriate location of the document, and, when the document is converted to HTML, the bookmark will be converted to an A NAME reference (also known as an internal link). With this reference, you can create a link in Header.txt that can be prepended to each Tutor document that allows the user to bypass repetitive sections. Tutor and Oracle ApplicationsRegarding accessibility, please check Oracle's website on accessibility http://www.oracle.com/accessibility/ to find out what version of E-Business Suite is certified to work with screen readers. Oracle Tutor 11.5.6A and greater works with screen readers such as JAWS.There is no certification between Oracle Tutor and Oracle Applications because there are no related dependencies. It doesn't matter which version of the Oracle Applications you are running. Therefore, it is possible to use Oracle Tutor with earlier versions of Oracle Applications.Oracle Business Process Converter and Oracle ApplicationsOracle Business Process Converter (OBPC) converts Visio, XPDL, and Tutor models to Oracle Business Process Architect and Oracle Business Process Management.

  • Content Based Routing with BRE and ESB

    - by Christopher House
    I've been working with BizTalk 2009 and the ESB toolkit for the past couple of days.  This is actually my first exposure to ESB and so far I'm pleased with how easy it is to work with. Initially we had planned to use UDDI for storing endpoint information.  However after discussing this with my client, we opted to look at BRE instead of UDDI since we're already storing transforms in BRE.  Fortunately making the change to BRE from UDDI was quite simple.  This solution of course has the added advantage of not needing to go through the convoluted process of registering our endpoints in UDDI. The first thing to remember if you want to do content based routing with BRE and ESB is that the pipleines included in the ESB toolkit don't include disassembler components.  This means that you'll need to first create a custom recieve pipeline with the necessary disassembler for your message type as well as the ESB components, itinerary selector and dispather. Next you need to create a BRE policy.  The ESB.ContextInfo vocabulary contains vocabulary links for the various items in the ESB context dictionary.  In this vocabulary, you'll find an item called Context Message Type, use this as the left hand side of your condition.  Set the right hand side to your message type, something like http://your.message.namespace/#yourrootelement.  Now find the ESB.EndPointInfo vocabulary.  This contains links to all the properties related to endpoint information.  Use the various set operators in your rule's action to configure your endpoint. In the example above, I'm using the WCF-SQL adapter. Now that the hard work is out of the way, you just need to configure the resolver in your itinerary. Nothing complicated here.  Just select BRE as your resolver implementation and select your policy from the drop-down list.  Note that when you select a policy, the Version field will be automatically filled in with the version of your policy.  If you leave this as-is, the resolver will always use that policy version.  Alternatively, you can clear the version number and the resolver will use the highest deployed version.

Put 1 week expiry header to all static files and unset ETag/last modified header. rewrite all js and css file to certain format. remove all the query parameters from URL forward all www.example.com to example.com The problem is only 1 and 2 are working. I tried a lot with many combinations but the expire and rewrite rule (3-6) do not work at all. I also tried moving these rules to apache2.conf and .htaccess files but it didn't work either. It does not give any error but these rules are simple ignored. expires and rewrite modules are ENABLED. Please let me know what should I do to fix this. 1. Do I need to add something else in httpd.conf file (like Options +FollowSymLink) or something else? 2. Do I need to add something in apache2.conf file? 3. Do I need to move these rules to .htaccess file? If yes, what should I write in that file and where should I keep that file? in /etc/apache2/ folder or /var/www/ folder? 4. Any other info to make this work? Thanks, Ankit

  • What Raid should I use for Website Static Files / Content

    - by Simon
    I'm building a Web server (IIS7) and would like to know the best practice for storing static content and the uploaded files of website's users (predominantly pictures, but also other documents like pdf's). I will keep the operating System on a Raid 1 array. Where should I be keeping the actual website's pages & files, it's own static content, and that of it's users? Should I be placing this content on a seperate raid array, and if so which type? I was considering using SLC SSD's (Such as the Intel's X25-e) but the following issues came to light. Will the SLC SSD's give any improvement over a 2.5" 15k SAS Drive for this type of content? If I did use SSD's, I'm under the belief I would still need to use Raid for redundancy, yet I've heard Intel X25-e's don't support TRIM. Does this scrap them as a legitimate option?

  • Using Upstart to manage Unicorn w/ rbenv + bundler binstubs w/ ruby-local-exec shebang

    - by codykrieger
    Alright, this is melting my brain. It might have something to do with the fact that I don't understand Upstart as well as I should. Sorry in advance for the long question. I'm trying to use Upstart to manage a Rails app's Unicorn master process. Here is my current /etc/init/app.conf: description "app" start on runlevel [2] stop on runlevel [016] console owner # expect daemon script APP_ROOT=/home/deploy/app PATH=/home/deploy/.rbenv/shims:/home/deploy/.rbenv/bin:$PATH $APP_ROOT/bin/unicorn -c $APP_ROOT/config/unicorn.rb -E production # >> /tmp/upstart.log 2>&1 end script # respawn That works just fine - the Unicorns start up great. What's not great is that the PID detected is not of the Unicorn master, it's of an sh process. That in and of itself isn't so bad, either - if I wasn't using the automagical Unicorn zero-downtime deployment strategy. Because shortly after I send -USR2 to my Unicorn master, a new master spawns up, and the old one dies...and so does the sh process. So Upstart thinks my job has died, and I can no longer restart it with restart or stop it with stop if I want. I've played around with the config file, trying to add -D to the Unicorn line (like this: $APP_ROOT/bin/unicorn -c $APP_ROOT/config/unicorn.rb -E production -D) to daemonize Unicorn, and I added the expect daemon line, but that didn't work either. I've tried expect fork as well. Various combinations of all of those things can cause start and stop to hang, and then Upstart gets really confused about the state of the job. Then I have to restart the machine to fix it. I think Upstart is having problems detecting when/if Unicorn is forking because I'm using rbenv + the ruby-local-exec shebang in my $APP_ROOT/bin/unicorn script. Here it is: #!/usr/bin/env ruby-local-exec # # This file was generated by Bundler. # # The application 'unicorn' is installed as part of a gem, and # this file is here to facilitate running it. # require 'pathname' ENV['BUNDLE_GEMFILE'] ||= File.expand_path("../../Gemfile", Pathname.new(__FILE__).realpath) require 'rubygems' require 'bundler/setup' load Gem.bin_path('unicorn', 'unicorn') Additionally, the ruby-local-exec script looks like this: #!/usr/bin/env bash # # `ruby-local-exec` is a drop-in replacement for the standard Ruby # shebang line: # # #!/usr/bin/env ruby-local-exec # # Use it for scripts inside a project with an `.rbenv-version` # file. When you run the scripts, they'll use the project-specified # Ruby version, regardless of what directory they're run from. Useful # for e.g. running project tasks in cron scripts without needing to # `cd` into the project first. set -e export RBENV_DIR="${1%/*}" exec ruby "$@" So there's an exec in there that I'm worried about. It fires up a Ruby process, which fires up Unicorn, which may or may not daemonize itself, which all happens from an sh process in the first place...which makes me seriously doubt the ability of Upstart to track all of this nonsense. Is what I'm trying to do even possible? From what I understand, the expect stanza in Upstart can only be told (via daemon or fork) to expect a maximum of two forks.

  • Apache2 - mod_expire and mod_rewrite not working in httpd.conf - serving content from tomcat

    - by Ankit Agrawal
    I am using apache2 server running on debian which forwards all the http request to tomcat installed on same machine. I have two files under my /etc/apache2/ folder apache2.conf and httpd.conf I modified httpd.conf file to look like following. # forward all http request on port 80 to tomcat ProxyPass / ajp://127.0.0.1:8009/ ProxyPassReverse / ajp://127.0.0.1:8009/ # gzip text content AddOutputFilterByType DEFLATE text/plain AddOutputFilterByType DEFLATE text/html AddOutputFilterByType DEFLATE text/xml AddOutputFilterByType DEFLATE text/css AddOutputFilterByType DEFLATE text/javascript AddOutputFilterByType DEFLATE application/xml AddOutputFilterByType DEFLATE application/xhtml+xml AddOutputFilterByType DEFLATE application/rss+xml AddOutputFilterByType DEFLATE application/javascript AddOutputFilterByType DEFLATE application/x-javascript DeflateCompressionLevel 9 BrowserMatch ^Mozilla/4 gzip-only-text/html BrowserMatch ^Mozilla/4\.0[678] no-gzip BrowserMatch \bMSIE !no-gzip !gzip-only-text/html # Turn on Expires and mark all static content to expire in a week # unset last modified and ETag ExpiresActive On ExpiresDefault A0 <FilesMatch "\.(jpg|jpeg|png|gif|js|css|ico)$" ExpiresDefault A604800 Header unset Last-Modified Header unset ETag FileETag None Header append Cache-Control "max-age=604800, public" </FilesMatch RewriteEngine On # rewrite all www.example.com/content/XXX-01.js and YYY-01.css files to XXX.js and YYY.css RewriteRule ^content/(js|css)/([a-z]+)-([0-9]+)\.(js|css)$ /content/$1/$2.$4 # remove all query parameters from URL after we are done with it RewriteCond %{THE_REQUEST} ^GET\ /.*\;.*\ HTTP/ RewriteCond %{QUERY_STRING} !^$ RewriteRule .* http://example.com%{REQUEST_URI}? [R=301,L] # rewrite all www.example.com to example.com RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC] RewriteRule ^(.*)$ http://example.com/$1 [R=301,L] I want to achieve following. forward all traffic to tomcat GZIP all the text content. Put 1 week expiry header to all static files and unset ETag/last modified header. rewrite all js and css file to certain format. remove all the query parameters from URL forward all www.example.com to example.com The problem is only 1 and 2 are working. I tried a lot with many combinations but the expire and rewrite rule (3-6) do not work at all. I also tried moving these rules to apache2.conf and .htaccess files but it didn't work either. It does not give any error but these rules are simple ignored. expires and rewrite modules are ENABLED. Please let me know what should I do to fix this. 1. Do I need to add something else in httpd.conf file (like Options +FollowSymLink) or something else? 2. Do I need to add something in apache2.conf file? 3. Do I need to move these rules to .htaccess file? If yes, what should I write in that file and where should I keep that file? in /etc/apache2/ folder or /var/www/ folder? 4. Any other info to make this work? Thanks, Ankit

  • Hide Content for Printing

    - by ltang
    Current, our users can view SCORM contents using frames. We would like to disable print or hide the content for printing. So far, we have tried: @media print { body { display:none } frameset {display:none} } The above line worked very inconsistently. For example, using IE8, the print preview does not show the content but when printing without preview it shows the content. Ideally we would like to disable printing altogether when our users launch any contents. If this can't be done, we would like to hide the print content so the users will print a blank page. Additionally, we would also like to disable the print screen option if possible. Please help!!!

  • HTTP Content-type header for cached files

    - by Brian
    Hello, Using Apache with mod_rewrite, when I load a .css or .js file and view the HTTP headers, the Content-type is only set correctly the first time I load it - subsequent refreshes are missing Content-type altogether and it's creating some problems for me. Specifically, gzip is not compressing these files. I can get around this by appending a random query string value to the end of each filename, eg. http://www.site.com/script.js?12345 However, I don't want to have to do that, since caching is good and all I want is for the Content-type to be present. I've tried using a RewriteRule to force the type but still didn't solve the problem. Any ideas? Thanks, Brian More Details: HTTP headers WITHOUT random query string value: http://localhost/script.js GET /script.js HTTP/1.1 Host: localhost User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 Accept: */* Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Referer: http://localhost/ Cookie: PHPSESSID=ke3p35v5qbus24che765p9jni5; If-Modified-Since: Thu, 29 Apr 2010 15:49:56 GMT If-None-Match: "3440e9-119ed-485621404f100" Cache-Control: max-age=0 HTTP/1.1 304 Not Modified Date: Thu, 29 Apr 2010 20:19:44 GMT Server: Apache/2.2.14 (Unix) mod_ssl/2.2.14 OpenSSL/0.9.8l DAV/2 PHP/5.3.1 Connection: Keep-Alive Keep-Alive: timeout=5, max=100 Etag: "3440e9-119ed-485621404f100" Vary: Accept-Encoding X-Pad: avoid browser bug HTTP headers WITH random query string value: http://localhost/script.js?c947344de8278053f6edbb4365550b25 GET /script.js?c947344de8278053f6edbb4365550b25 HTTP/1.1 Host: localhost User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 Accept: */* Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Referer: http://localhost/ Cookie: PHPSESSID=ke3p35v5qbus24che765p9jni5; HTTP/1.1 200 OK Date: Thu, 29 Apr 2010 20:14:40 GMT Server: Apache/2.2.14 (Unix) mod_ssl/2.2.14 OpenSSL/0.9.8l DAV/2 PHP/5.3.1 Last-Modified: Thu, 29 Apr 2010 15:49:56 GMT Etag: "3440e9-119ed-485621404f100" Accept-Ranges: bytes Vary: Accept-Encoding Content-Encoding: gzip Content-Length: 24605 Keep-Alive: timeout=5, max=100 Connection: Keep-Alive Content-Type: application/javascript

  • Cannot log into Oracle Enterprise Manager 11g: ORA-28001

    - by Álvaro G. Vicario
    I can no longer log into Oracle Enterprise Manager 11g. I get this error message: ORA-28001: the password has expired (DBD ERROR: OCISessionBegin) I could log into the server using SQL*Plus. I warned me that the password was going to expire in 7 days (which is not the same as being already expired). Following advice from several documents, I ran these commands from SQL*Plus: ALTER USER sys IDENTIFIED BY new_password; ALTER USER system IDENTIFIED BY new_password; SQL*Plus no longer warns about passwords, but I still cannot use the Enterprise Manager. Then I followed this to remove password expiration: ALTER PROFILE default LIMIT password_life_time UNLIMITED And I've also restarted the Oracle services. In case it was using cached credentials, I've tried to connect from several browsers in several computers. No way: I still get ORA-28001 in Enterprise Manager. What am I missing?

  • fade in all divs of a page. once the content of the divs is loaded

    - by daniel
    I want all the divs on my page to fade in after the content is loaded. The code below loads in all imgs in the #div container. Which is great. but it does not load in images that are used as div background images loaded through the css file. So i think the most effective way is to create a piece of code that fades in all the divs on the page after the content ie: images and text has loaded. Is there A way to do this. Cheers. $(document).ready(function() { $('#container img').fadeIn(4000); // and tell pending images to do the same, once they've finished loading: $('#container img').load(function () { $(this).fadeIn(4000); }); });

  • Creating a VS 2010 Project with only content files.

    - by Cameron Peters
    I have some content files that I would like to share between a number of projects in Visual Studio. I have put these files in their own project, set the build action to "Content", and the copy to output directory to "Copy if newer". I would like all these files to be copied to the bin/debug directory of the projects that reference them. I can get it to work by including a reference to the "contents" project in each of the projects that need the files, but that requires that a minimal assembly be generated (3K). I assume there is a way, using MSBuild, to make this all work without creating the empty assembly?

  • WordPress plugin to output a certain category on content page tweak help

    - by talkingD0G
    I'm using WordPress plugin Category Page to display the most recent 5 posts from a certain category on a regular content page (not the blog page) of a website. Right now the plugin is limited to display the post title linked to the post page. This is a video blog type site and I need the plugin to display the post title (as it does now) with the video as well. Probably just telling the script to show the content would work but I don't know how to tweak it. This is the section of the script that is outputting the post title: function page2cat_content_catlist($content){ global $post; if ( stristr( $content, '[catlist' )) { $search = "@(?:<p>)*\s*\[catlist\s*=\s*(\w+|^\+)\]\s*(?:</p>)*@i"; if (preg_match_all($search, $content, $matches)) { if (is_array($matches)) { $title = get_option('p2c_catlist_title'); if($title != "") $output = "<h4>".$title."</h4>"; else $output = ""; $output .= "<ul class='p2c_catlist'>"; $limit = get_option('p2c_catlist_limit'); foreach ($matches[1] as $key =>$v0) { $catposts = get_posts('category='.$v0."&numberposts=".$limit); foreach($catposts as $single): $output .= "<li><a href='".get_permalink($single->ID)." '>".$single->post_title."</a></li>"; endforeach; $search = $matches[0][$key]; $replace= $output; $content= str_replace ($search, $replace, $content); } $output .= "</ul>"; } } } return $content; } If anyone has any advice or knows how to help thanks in advance!

  • IIS: Content-Length 0 for CSS, Javascript and Images

    - by Adrian Grigore
    After a clean re-installation of my Windows 7 system, I can't get IIS 7 to properly deliver any static content. Dynmic content (ASPX pages and content served by ASP.NET MVC controllers) works fine, but static files such as CSS, Javascript and Images give me a 200 OK status code and a Content-Length of 0. The problem occurs with all web sites on my server, even a brandnew ASP:NET MVC template project with no changes. It also occurs with both Firefox and IE 8. What could possibly be the problem? Note that I also installed the latest Windows Azure SDK, perhaps that messed up some settings. But I don't know how to proceed with for troubleshooting this.
