• Report article to admin in joomla

  - by moustafa

  Hi there, Is there any such feature in Joomla 1.5 that allows users to report a particular published article to the moderator. In some instances, the article may be offensive to some viewers in one way or the other. There could be a link Report to moderator which shall inform the moderator about that particular article. I understand that the admin or the moderator shall approve the article before posting. I would also like my registered users to be able to report. Is there any plugin that does this trick?

• Javascript substrings multiline replace by RegExp

  - by Radek Šimko

  Hi, I'm having some troubles with matching a regular expression in multi-line string. <script> var str="Welcome to Google!\n"; str = str + "We are proud to announce that Microsoft has \n"; str = str + "one of the worst Web Developers sites in the world."; document.write(str.replace(/.*(microsoft).*/gmi, "$1")); </script> http://jsbin.com/osoli3/3/edit As you may see on the link above, the output of the code looks like this: Welcome to Google! Microsoft one of the worst Web Developers sites in the world. Which means, that the replace() method goes line by line and if there's no match in that line, it returns just the whole line... Even if it has the "m" (multiline) modifier...

• Raw Video file from website

  - by Charlie

  I would like to make an app that will download videos files that can be played later. At first i thought I could have a UIWeb view and then try to access the cache of it and get the file that way but unfortunately i don't have access to that. After trying that my next thought would be get the direct link to the video file. Essentially what download helper does on fire fox. Any idea of where i could look at for help or any body have any better idea? Is there any stringByEvaluatingjavascript that might be of use or is there away to access the cache on a webview in your own app? Thanks for any help!

• Hot to get custom http-header in asp.net?

  - by Sirius Lampochkin

  I have an asp.net appliction on the one server. There I've added code on server-side in Page_Load: Response.AddHeader("key", "password-key-from-hotel"); On the client side I have a form: $lt;form ... action="www.link-to-another-domaint" >   <input type="hidden" id="asd" value="fgh" > .... </form> <script type="text/javascript">   document.forms[0].submit(); </script> Then on the other domain - there is also my other application - I'm trying to get the hedaer "key" by this code: Request.Headers["key"].ToString(); But there is no such header. Is there is a desicion? Where is my mistake?

• Service Layer Patter - Could we avoid the service layer on a specific case?

  - by lidermin

  Hi, we are trying to implement an application using the Service Layer Pattern cause our application needs to connect to other multiple applications too, and googling on the web, we found this link of a demostrative graphic for the "right" way of apply the pattern: martinfowler.com - Service Layer Pattern But now we have a question: what if our system needs to implement some business logic, only for our application (like some maintenance data for the system itself) that we don't need to share with other systems. Based on this graphic: As it seems, it will be unnecesary to implement a service layer just for that; it will be more practical to avoid the service layer, and just go from User Interface to the Business Layer (for example). What should be the right way in this case to implement the Service Layer Pattern? What do you suggest us for a scenario like the one I told you? Thanks in advance.

• Problem building PyGTK on CentOS

  - by Marcelo Cantos

  I am trying to build PyGTK on CentOS for a non-standard Python (2.6, vs the out-of-the-box 2.4). It requires that I first build pygobject. pygobject-2.18.0 fails at the configure step. The error messages is as follows: checking for GLIB - version >= 2.14.0... no *** Could not run GLIB test program, checking why... *** The test program failed to compile or link. See the file config.log for the *** exact error that occured. This usually means GLIB is incorrectly installed. configure: error: maybe you want the pygobject-2-4 branch? I have downloaded, built and successfully installed glib. The config.log file contains the following output: configure:6893: gcc -E conftest.c conftest.c:13:28: error: ac_nonexistent.h: No such file or directory What am I doing wrong?

• Redirects in RoR: Which one to use?

  - by scrr

  Hello, we are making a website that takes a generated incoming link and forwards the user who is clicking on it to another website while saving a record of the action in our DB. I guess it's basically what ad-services like AdSense do. However, what is the best way to redirect the user? I think html-meta-tag-redirects are out of question. So what other options are there? head :moved_permanently, :location => "http://www.domain.com/" This one is a 301-redirect. The next one is a 302: redirect_to "http://www.domain.com" Are there any others? And which is best to use for our case? The links are highly-dynamic and change all the time. We want to make sure we don't violate any existing standards and of course we don't want search-engines to tag us as spammers (which we are not, btw). Thanks!

• a question on webpage data scraping using Java

  - by Gemma

  Hi there. I am now trying to implement a simple HTML webpage scraper using Java.Now I have a small problem. Suppose I have the following HTML fragment. <div id="sr-h-left" class="sr-comp"> <a class="link-gray-underline" id="compare_header" rel="nofollow" href="javascript:i18nCompareProd('/serv/main/buyer/ProductCompare.jsp?nxtg=41980a1c051f-0942A6ADCF43B802'); " Compare Showing 1 - 30 of 1,439 matches, The data I am interested is the integer 1.439 shown at the bottom.I am just wondering how can I get that integer out of the HTML. I am now considering using a regular expression,and then use the java.util.Pattern to help get the data out,but still not very clear about the process. I would be grateful if you guys could give me some hint or idea on this data scraping. Thanks a lot.

• C# progress bar not synced with download (WebClient class)

  - by dominiquel

  Hi, I am coding a system which has a small FTP module included inside, it's not the main feature at all, but needed... I must link the progressbar with the WebClient class event DownloadProgressChangedEventHandler and AsyncCompletedEventHandler, the progressbar increment is ok, and the ASyncCompletedEventHandler launch a MessageBox (as intended), the problem is that the progress bar see to load too slow... problem : My MessageBox pop at 100% (launched by the event handler), BUT when the MessageBox pop my progress bar is only at +-80% (but the .VALUE is really 100), the first though I had was that they have added a "smooth" effect in Windows Vista which slow down the progressbar relatively to it's true value. If any of you have experienced the same problem thanks for your help.

• ASP.NET MVC thinks my virtual directory is a controller

  - by kmehta

  I have a virtual directory under my MVC website in IIS called "Files". This directory is at the same level as my Views directory. When I link to a file from my MVC app to a file under my Files directory, I get the following error: The controller for path '/Files/Images/1c7f7eb8-5d66-4bca-a73a-4ba6340a7805.JPG' was not found or does not implement IController. It thinks that my Files VD is a controller. How do I access my files like a normal VD without MVC interfering? Thanks.

  Hey i am trying to calculate a cosinor analysis in statistica but am at a loss as to how to do so. I need to calculate the MESOR, AMPLITUDE, and ACROPHASE of ciracadian rhythm data. http://www.wepapers.com/Papers/73565/Cosinor_analysis_of_accident_risk_using__SPSS%27s_regression_procedures.ppt there is a link that shows how to do it, the formulas and such, but it has not given me much help. Does anyone know the code for it, either in statistica or SPSS?? I really need to get this done because it is for my thesis paper at UC Berkeley, if anyone can offer any help it would be so awesome.

• Slicing the EDG

  - by Antony Reynolds

  Different SOA Domain Configurations In this blog entry I would like to introduce three different configurations for a SOA environment.  I have omitted load balancers and OTD/OHS as they introduce a whole new round of discussion.  For each possible deployment architecture I have identified some of the advantages. Super Domain This is a single EDG style domain for everything needed for SOA/OSB.   It extends the standard EDG slightly but otherwise assumes a single “super” domain. This is basically the SOA EDG.  I have broken out JMS servers and Coherence servers to improve scalability and reduce dependencies. Key Points Separate JMS allows those servers to be kept up separately from rest of SOA Domain, allowing JMS clients to post messages even if rest of domain is unavailable. JMS servers are only used to host application specific JMS destinations, SOA/OSB JMS destinations remain in relevant SOA/OSB managed servers. Separate Coherence servers allow OSB cache to be offloaded from OSB servers. Use of Coherence by other components as a shared infrastructure data grid service. Coherence cluster may be managed by WLS but more likely run as a standalone Coherence cluster. Benefits Single Administration Point (1 Admin Server) Closely follows EDG with addition of application specific JMS servers and standalone Coherence servers for OSB caching and application specific caches. Coherence grid can be scaled independent of OSB/SOA. JMS queues provide for inter-application communication. Drawbacks Patching is an all or nothing affair. Startup time for SOA may be slow if large number of composites deployed. Multiple Domains This extends the EDG into multiple domains, allowing separate management and update of these domains.  I see this type of configuration quite often with customers, although some don't have OWSM, others don't have separate Coherence etc. SOA & BAM are kept in the same domain as little benefit is obtained by separating them. Key Points Separate JMS allows those servers to be kept up separately from rest of SOA Domain, allowing JMS clients to post messages even if other domains are unavailable. JMS servers are only used to host application specific JMS destinations, SOA/OSB JMS destinations remain in relevant SOA/OSB managed servers. Separate Coherence servers allow OSB cache to be offloaded from OSB servers. Use of Coherence by other components as a shared infrastructure data grid service. Coherence cluster may be managed by WLS but more likely run as a standalone Coherence cluster. Benefits Follows EDG but in separate domains and with addition of application specific JMS servers and standalone Coherence servers for OSB caching and application specific caches. Coherence grid can be scaled independent of OSB/SOA. JMS queues provide for inter-application communication. Patch lifecycle of OSB/SOA/JMS are no longer lock stepped. JMS may be kept running independently of other domains allowing applications to insert messages fro later consumption by SOA/OSB. OSB may be kept running independent of other domains, allowing service virtualization to continue independent of other domains availability. All domains use same OWSM policy store (MDS-WSM). Drawbacks Multiple domains to manage and configure. Multiple Admin servers (single view requires use of Grid Control) Multiple Admin servers/WSM clusters waste resources. Additional homes needed to enjoy benefits of separate patching. Cross domain trust needs setting up to simplify cross domain interactions. Startup time for SOA may be slow if large number of composites deployed. Shared Service Environment This model extends the previous multiple domain arrangement to provide a true shared service environment.This extends the previous model by allowing multiple additional SOA domains and/or other domains to take advantage of the shared services.  Only one non-shared domain is shown, but there could be multiple, allowing groups of applications to share patching independent of other application groups. Key Points Separate JMS allows those servers to be kept up separately from rest of SOA Domain, allowing JMS clients to post messages even if other domains are unavailable. JMS servers are only used to host application specific JMS destinations, SOA/OSB JMS destinations remain in relevant SOA/OSB managed servers. Separate Coherence servers allow OSB cache to be offloaded from OSB servers. Use of Coherence by other components as a shared infrastructure data grid service Coherence cluster may be managed by WLS but more likely run as a standalone Coherence cluster. Shared SOA Domain hosts Human Workflow Tasks BAM Common "utility" composites Single OSB domain provides "Enterprise Service Bus" All domains use same OWSM policy store (MDS-WSM) Benefits Follows EDG but in separate domains and with addition of application specific JMS servers and standalone Coherence servers for OSB caching and application specific caches. Coherence grid can be scaled independent of OSB/SOA. JMS queues provide for inter-application communication. Patch lifecycle of OSB/SOA/JMS are no longer lock stepped. JMS may be kept running independently of other domains allowing applications to insert messages fro later consumption by SOA/OSB. OSB may be kept running independent of other domains, allowing service virtualization to continue independent of other domains availability. All domains use same OWSM policy store (MDS-WSM). Supports large numbers of deployed composites in multiple domains. Single URL for Human Workflow end users. Single URL for BAM end users. Drawbacks Multiple domains to manage and configure. Multiple Admin servers (single view requires use of Grid Control) Multiple Admin servers/WSM clusters waste resources. Additional homes needed to enjoy benefits of separate patching. Cross domain trust needs setting up to simplify cross domain interactions. Human Workflow needs to be specially configured to point to shared services domain. Summary The alternatives in this blog allow for patching to have different impacts, depending on the model chosen.  Each organization must decide the tradeoffs for itself.  One extreme is to go for the shared services model and have one domain per SOA application.  This requires a lot of administration of the multiple domains.  The other extreme is to have a single super domain.  This makes the entire enterprise susceptible to an outage at the same time due to patching or other domain level changes.  Hopefully this blog will help your organization choose the right model for you.

• Delete Button issue

  Hi, I am using one link button in an asp.net application for delete purpose. For the confirmation i added the property of OnClientclick="return ValidateOnDelete();". By Default it works as fine. But i have One condition is that When the user is not admin, the delete button will be disabled. My problem is that, if the user clicks on the delete button when it is in disabled mode, the confirmation message will come. How it can avoid this issue?

• How to subString a block of user generated HTML while preserving formatting?

  - by Chad

  I'd like to create the typical preview paragraph with a [read more] link. Problem is, the content that I'd like to SubString() contains text and html, written by a user with a WYSIWYG editor. Of course, I check to make sure the string is not null or empty, then SubString() it, problem is that I could end up breaking the html tags, throwing off the rendering of the entire site. The WYSIWYG editor doesn't seem to create perfectly formatted HTML, and many times seems to use <br /> tags instead of <p></p>, etc... basically, I can't rely on well-formed tags, etc. My workaround was to just strip out all HTML and substring the leftover text. This works, but loses any of the formatting that was in the HTML. What's the best method of SubString()'ing a block of non-well-formed HTML while maintaining HTML that won't break the rendering of the site?

• How can I calculate data for a boxplot (quartiles, median) in a Rails app on Heroku? (Heroku uses Po

  - by hadees

  I'm trying to calculate the data needed to generate a box plot which means I need to figure out the 1st and 3rd Quartiles along with the median. I have found some solutions for doing it in Postgresql however they seem to depend on either PL/Python or PL/R which it seems like Heroku does not have either enabled for their postgresql databases. In fact I ran "select lanname from pg_language;" and only got back "internal". I also found some code to do it in pure ruby but that seems somewhat inefficient to me. I'm rather new to Box Plots, Postgresql, and Ruby on Rails so I'm open to suggestions on how I should handle this. There is a possibility to have a lot of data which is why I'm concerned with performance however if the solution ends up being too complex I may just do it in ruby and if my application gets big enough to warrant it get my own Postgresql I can host somewhere else. *note: since I was only able to post one link, cause I'm new, I decided to share a pastie with some relevant information

• Jquery load() help

  - by mtwallet

  Hi. I am creating a portfolio page for m personal site. I have a slider with approx 20 anchors that link to projects I have worked on, each one contains a client logo that when clicked should load some html content then fade that content into a container div on the same page. I have been advised to use the JQuery method load() which seems straight forward. The question I have is do I have to repeat the following code for each of the 20 anchors as the url is different for each one or is there a more efficient way? $('a#project1').click(function() { $('#work').load('ajax/project1.html'); } Also would I have to use the unload() method first to ensure the div I am loading into is empty? Many thanks in advance.

• A little bit more complicated multiview App for Iphone

  - by Thomas Losert

  Hi, i'm new to iphone development. I spend several days by looking for how write muliview app for an Iphone OS. I found how to switch the diferent views without navigation hierarchy (in this article). It's great, but i want more complicated function. For example, i have three diferent views (view 1 - 3) and i can switch between them with technique from link 1. It works fine. My question is: How can i put UITabBarController on view 2, that shows own subviews (tabView 1 - 3) and how put UINavigationController on view 3, that shows own subviews (navView 1 - 2)? The reslut should look like that, one main view (view 1) with two buttons (for example), which switch me to "window" with UiTabBarController or UINavigationController. I found only tutorials, where UITabBarController was a first controller class, that shows directly from AppDelegate (something like default Xcode predefined scenarios). Thanks for your helpfull answer, or i will be crazy soon:).

• How does mysql define DISTINCT()

  - by goran

  AFAIK SQL defines two uses of DISTINCT keywords - SELECT DISTINCT field... and SELECT COUNT(DISTINCT field) ... However in one of web applications that I administer I've noticed performance issues on queries like SELECT DISTINCT(field1), field2, field3 ... DISTINCT() on a single column makes no sense and I am almost sure it is interpreted as SELECT DISTINCT field1, field2, field3 ... but how can I prove this? I've searched mysql site for a reference on this particular syntax but could not find any. Does anyone have a link to definition of DISTINCT() in mysql or knows about other authoritative source on this? Best

• Generate an image / thumbnail of a webpage using X/Gui-less linux

  - by dassouki

  There are a lot of solutions out there on generating a thumbnail or an image preview of a webpage. Some of these are websites like websnapshots, windows libraries such as PHP's imagegrabscreen (only works on windows), and KDE's wkhtml. Many more do exist. However, I'm looking for a GUI-less solution. Something I can create an API around and link it to php or python. I'm comfortable with python, php, C, and shell. This is a personal project, so I'm not interested in commercial applications as I'm aware of their existence. Any ideas?

• Memcache failover and consistent hashing

  - by Industrial

  Hi everyone, I am trying to work out a good way to handle offline/down memcached servers in my current web application that are built with PHP. I just found this link that shows an approach on how to do what I want, I think: http://cmunezero.com/2008/08/11/consistent-memcache-hashing-and-failover-with-php/ Anyhow, it gets me confused when I start working with it and reading the PHP documention about failover with memcache. Why is offline memcache servers added to the $realInstance server pool together with the online servers? Reading the memcache documentation confuses me even more: http://www.php.net/manual/en/memcache.addserver.php status Controls if the server should be flagged as online. Setting this parameter to FALSE and retry_interval to -1 allows a failed server to be kept in the pool so as not to affect the key distribution algorithm. Requests for this server will then failover or fail immediately depending on the memcache.allow_failover setting. Default to TRUE, meaning the server should be considered online. Thanks,

• Code Analysis Error: Declare types in namespaces

  - by George

  Is VS2010, I analyzed my code and got this error: Warning 64 CA1050 : Microsoft.Design : 'ApplicationVariables' should be declared inside a namespace. C:\My\Code\BESI\BESI\App_Code\ApplicationVariables.vb 10 C:\...\BESI\ Here is some reference info on the error. Essentially, I tried to create a class to be used to access data in the Application object in a typed way. The warning message said unless I put my (ApplicationVariables) class in a Namespace, that I wouldn't be able to use it. But I am using it, so what gives? Also, here is a link to another StackOverflow article that talks about how to disable this warning in VS2008, but how would you disable it for 2010? There is no GlobalSuppressions.vb file for VS2010. Here is the code it is complaining a bout: Public Class ApplicationVariables 'Shared Sub New() 'End Sub 'New Public Shared Property PaymentMethods() As PaymentMethods Get Return CType(HttpContext.Current.Application.Item("PaymentMethods"), PaymentMethods) End Get Set(ByVal value As PaymentMethods) HttpContext.Current.Application.Item("PaymentMethods") = value End Set End Property 'Etc, Etc...

• Sign in as different user when using Integrated Windows Authentication

  - by Sam

  I have restricted access to a site by using Integrated Windows Authentication and turning off anonymous access. This way I can then show them their real name (from looking up on Active Directory and using the server variable LOGON_USER) and do other related Active Directory tasks. How can I then prompt again for their user credentials, through a 'sign in as other user' link , showing the browser prompt (like you would get on a browser like Chrome or Firefox, or if the site was not in the 'Intranet' zone in IE) rather than a Web Form? Since SharePoint offers this functionality, I assume there is a way to do this through code, but I don't know what code can do this (using C#). I can send a 401 header which makes the prompt appear, but how do you then confirm if they are logged in?
