• git merge with renamed files

  - by Kevin

  I have a large website that I am moving into a new framework and in the process adding git. The current site doesn't have any version control on it. I started by copying the site into a new git repository. I made a new branch and made all of the changes that were needed to make it work with the new framework. One of those steps was changing the file extension of all of the pages. Now in the time that I have been working on the new site changes have been made to files on the old site. So I switched to master and copied all of those changes in. The problem is when I merge the branch with the new framework back onto master there is a conflict on every file that was changed on the master branch. I wouldn't be to worried about it but there are a couple of hundred files with changes. I have tried git rebase and git rebase --merge with no luck. How can I merge these 2 branches without dealing with every file?

• Finding Common Phrases in MS SQL TEXT Column

  - by regex

  Hello All, Short Desc: I'm curious to see if I can use SQL Analysis services or some other MS SQL service to mine some data for me that will show commonalities between SQL TEXT fields in a dataset. Long Desc I am looking at a subset of data that consists of about 10,000 rows of TEXT blobs which are used as a notes column in a issue tracking (ticketing) software. I would like to use something out of the box (without having to build something) that might be able to parse through all of the rows and find commonly used byte sequences in the "Notes" column. In other words, I want to find commonly used phrases (two to three word phrases, so 9 - 20 character sections of the TEXT blob). This will help me better determine if associate's notes contain similar phrases (troubleshooting techniques) that we could standardize in our troubleshooting process flow. Closing Note I'd really rather not build an application to do this as my method will probably not be the most efficient way to do it. Hopefully all this makes sense. Please let me know in the comments if anything needs clarification. Thanks in advance for your help.

• PHP Single Sign On (SSO) generating new session id

  - by bigstylee

  I am trying to create a single sign on process. The method I have implemented makes use of storing session data in a database. When a new user comes to the website (www.example2.com) a table of authentication is checked. As this is their first visit to the website, there will be no match. The browser is redicted to the authentication server www.example1.com/authenticate.php?session_id=ABC123 where ABC123 represents the session id created on www.example2.com. THe session id which is then generated on www.example1.com is stored along side the session id using the parameter set in the URL. The user is then redirected back to the www.example2.com and a match of session ids should be found. This WAS working fine in FireFox but when I tried it in Chrome I noticed that the session id being generated when the browser is redirected back to www.example2.com is a new session id. As a result an infinite loop is created. This behaviour has not manifested itself in FireFox aswell. What is causing the new session id to be generated? More importantly, what can I do to stop it? Thanks in advance! EDIT I had a logically error that was causing an infinite loop. This now works fine again in FireFox but the infinite loop is still occuring in Chrome and Internet Explorer.

• HttpWebRequest.BeginGetResponse() does not return the second time

  - by evilfred

  Hi, I make one HttpWebRequest and call GetResponse() on it to get a synchronous response. Then after processing that response, I make a new HttpWebRequest and call BeginGetResponse() on it. Since BeginGetResponse() is an asynchronous call I expect it to return right away, but it doesn't! Why not? Here is some stripped down sample code: HttpWebRequest request = RequestFactory.MakeSessionCreationRequest(); try { // Get the response from the server. using (WebResponse response = request.GetResponse()) { using (Stream responseStream = response.GetResponseStream()) { ; // Get the response. } } ; // Process the response. } catch (WebException e) { Logger("Caught WebException when attempting to connect: " + e); return; } // Make the second, asynchronous request. HttpWebRequest msgRequest = RequestFactory.MakeMessageRequest(); IAsyncResult result = msgRequest.BeginGetResponse( new AsyncCallback(HandleResponse), msgRequest); // PROBLEM: This line is never reached!!! Logger("Message send started");

• Check for modification failure in content Integration using visualSvn sever and cruise control.net

  - by harun123

  I am using CruiseControl.net for continous integration. I've created a repository for my project using VisualSvn server (uses Windows Authentication).

• ASP.NET Memory Usage in IIS is FAR greater than in DevEnv. Is this normal?

  - by Tom

  Greetings! I have an ASP.NET app that scrapes data from a handful of external pages, parses the relevant bits and displays them in a table. Total data retrieved is 3-4MB and the resulting page is about 1MB. I am using synchronous WebRequest GetResponse for the retrieval, but the same problem existed using an asynchronous BeginGetResponse/EndGetResponse process. There is no database access, no session storage, no caching, but an in-memory list of about 100 objects (total 1MB of data), plus a good amount of AJAX (AjaxControlToolkit). This issue appears on the very first run of the app, even if I have restarted IIS. The issue: When I run the app on my dev computer, the maximum commit charge is about 1.5GB. The biggest user, measured by Task Manager's VM Size, is WebDev.WebServer.exe (600MB). The app runs perfectly. When I run it on my rent-a-server (IIS 7.5, 1GB RAM), the maximum commit charge is over 3.8GB. The biggest user is w3wp.exe at 2.7GB. IIS grinds to a halt and spits out a timed-out error page. Given my limited server budget and the hope of having multiple simultaneous users, I'm kind of in a panic. Is this normal? If I bump the server RAM up to 4GB, will that be enough? Will multiple users require even more memory? Could the culprit be AJAX or the list of objects? Thanks for any insight you can provide.

• Silverlight 3 + Java WebService

  - by Heko

  Hello! I have a Silverlight 3 project, and I need to call a Java WebService - the bindings are ok (SOAP 1.1 and basicHttpBinding): ClientConfig File: <configuration> <system.serviceModel> <bindings> <basicHttpBinding> <binding name="SkyinfoTestInterfaceExport2_SkyinfoTestInterfaceHttpBinding" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"> <security mode="None"> <transport> <extendedProtectionPolicy policyEnforcement="Never" /> </transport> </security> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="myAddress" binding="basicHttpBinding" bindingConfiguration="SkyinfoTestInterfaceExport2_SkyinfoTestInterfaceHttpBinding" contract="SkyInfoServiceReference.SkyinfoTestInterface" name="SkyinfoTestInterfaceExport2_SkyinfoTestInterfaceHttpPort" /> </client> </system.serviceModel> When I call a method on client I get this Policy error: An error occurred while trying to make a request to URI '...'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details. I know about those 2 policy XML filesbut Java EE service which I'm trying to call is hosted on a IBM WebSphere Process Server to which I don't have access. Does anybody know how to work around this policy exception?

• 3 tier application pattern suggestion

  - by Maxim Gershkovich

  I have attempted to make my first 3 tier application. In the process I have run into one problem I am yet to find an optimal solution for. Basically all my objects use an IFillable interface which forces the implementation of a sub as follows Public Sub Fill(ByVal Datareader As Data.IDataReader) Implements IFillable.Fill This sub then expects the Ids from the datareader will be identical to the properties of the object as such. Me.m_StockID = Datareader.GetGuid(Datareader.GetOrdinal("StockID")) In the end I end up with a datalayer that looks something like this. Public Shared Function GetStockByID(ByVal ConnectionString As String, ByVal StockID As Guid) As Stock Dim res As New Stock Using sqlConn As New SqlConnection(ConnectionString) sqlConn.Open() res.Fill(StockDataLayer.GetStockByIDQuery(sqlConn, StockID)) End Using Return res End Function Mostly this pattern seems to make sense. However my problem is, lets say I want to implement a property for Stock called StockBarcodeList. Under the above mentioned pattern any way I implement this property I will need to pass a connectionstring to it which obviously breaks my attempt at layer separation. Does anyone have any suggestions on how I might be able to solve this problem or am I going about this the completely wrong way? Does anyone have any suggestions on how I might improve my implementation? Please note however I am deliberately trying to avoid using the dataset in any form.

• Help me understand dynamic layouts in Sinatra

  - by thermans

  Help me understand this; I'm learning Sinatra (and Rails for that matter, er, and Ruby). Say I'm doing a search app. The search form is laid out in one div, and the results will be laid out in another. The search form is rendered into the div by a previous view (maybe from a login form). I want to process the form params, perform the search, and render the results into the results div. If I have a single "yield" in the layout and render the divs from different views, the results div erases the search div when it renders. If I define the divs in the default layout, then just render the content, obviously the layout will be messed up: there would have to be two "yields" and I don't think Sinatra supports passing blocks in to yields. I tried foca's sinatra-content-for plugin, and that seems closer to what I need. But I can't figure out where to place the "yield_content" statements. If I have this haml in my layout: #search -# search form = yield_content :search #results -# search results = yield_content :results ... this in my search view: - content_for :search do %form{:method => "post"... etc. ... and this in the results view: - content_for :results do %table{:class => 'results'... etc. This sort of works but when I render the results view, the search div is emptied out. I would like to have it remain. Am I doing something wrong? How should I set this up?

• I need a true mouseOver...

  - by invertedSpear

  Ok, so mouseOver and RollOver, and their respective outs work great as long as your mouse is actually over the item, or one of it's children. My problem is that I may have another UI component "between" my mouse and the item I want to process the mouse/rollover(maybe a button that is on top of a canvas, but is not a child of the canvas). The mouse is still over the component, there's just something else that it's over at the same time. Any tips or help how to deal with this? Let me know if I'm not being clear enough. Here is a simplified code example detailing my question copy/paste that into your flex/flash builder and you'll see what I mean: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="500" height="226" creationComplete="ccInit()"> <mx:Script> <![CDATA[ private function ccInit():void{ myCanv.addEventListener(MouseEvent.ROLL_OVER,handleRollOver); } private function handleRollOver(evt:MouseEvent):void{ myCanv.setStyle("backgroundAlpha",1); myCanv.addEventListener(MouseEvent.ROLL_OUT,handleRollOut); } private function handleRollOut(evt:MouseEvent):void{ myCanv.setStyle("backgroundAlpha",0); myCanv.removeEventListener(MouseEvent.ROLL_OUT,handleRollOut); } ]]> </mx:Script> <mx:Canvas id="myCanv" x="10" y="10" width="480" height="200" borderStyle="solid" borderColor="#000000" backgroundColor="#FFFFFF" backgroundAlpha="0"> </mx:Canvas> <mx:Button x="90" y="50" label="Button" width="327" height="100"/> </mx:Application>

• Skip Checkout in Magento for a downloadable product

  - by Aaron Newton

  Hello Magento boffins. I am using Magento to build an eBooks site. For the release, we plan to have a number of free downloadable books. We were hoping that it would be possible to use the normal Magento 'catalog' functionality to add categories with products underneath. However, since these are free downloadable products, it doesn't really make sense to send users through the checkout when they try to download. Does anyone know of a way to create a free downloadable product which bypasses the checkout altogether? I have noticed that there is a 'free sample' option for downloadable products, but I would prefer not to use this if I can as I plan to use this field for its intended purpose when I add paid products. [EDIT] I have noticed that some of you have voted this question down for 'lack of question clarity'. For clarity, I want: to know if it is possible to create a downloadable product in Magento which doesn't require users to go through the usual checkout process (since it is free) and which is not the 'Free Sample' field of a downloadable product Unfortunately I don't think I can ask this any more eloquently. [/EDIT]

• Optimizing processing and management of large Java data arrays

  - by mikera

  I'm writing some pretty CPU-intensive, concurrent numerical code that will process large amounts of data stored in Java arrays (e.g. lots of double[100000]s). Some of the algorithms might run millions of times over several days so getting maximum steady-state performance is a high priority. In essence, each algorithm is a Java object that has an method API something like: public double[] runMyAlgorithm(double[] inputData); or alternatively a reference could be passed to the array to store the output data: public runMyAlgorithm(double[] inputData, double[] outputData); Given this requirement, I'm trying to determine the optimal strategy for allocating / managing array space. Frequently the algorithms will need large amounts of temporary storage space. They will also take large arrays as input and create large arrays as output. Among the options I am considering are: Always allocate new arrays as local variables whenever they are needed (e.g. new double[100000]). Probably the simplest approach, but will produce a lot of garbage. Pre-allocate temporary arrays and store them as final fields in the algorithm object - big downside would be that this would mean that only one thread could run the algorithm at any one time. Keep pre-allocated temporary arrays in ThreadLocal storage, so that a thread can use a fixed amount of temporary array space whenever it needs it. ThreadLocal would be required since multiple threads will be running the same algorithm simultaneously. Pass around lots of arrays as parameters (including the temporary arrays for the algorithm to use). Not good since it will make the algorithm API extremely ugly if the caller has to be responsible for providing temporary array space.... Allocate extremely large arrays (e.g. double[10000000]) but also provide the algorithm with offsets into the array so that different threads will use a different area of the array independently. Will obviously require some code to manage the offsets and allocation of the array ranges. Any thoughts on which approach would be best (and why)?

• does lucene search function work in large size document?

  - by shaon-fan

  Hi,there I have a problem when do search with lucene. First, in lucene indexing function, it works well to huge size document. such as .pst file, the outlook mail storage. It can build indexing file include all the information of .pst. The only problem is to large sometimes, include very much words. So when i search using lucene, it only can process the front part of this indexing file, if one word come out the back part of the indexing file, it couldn't find this word and no hits in result. But when i separate this indexing file to several parts in stupid way when debugging, and searching every parts, it can work well. So i want to know how to separate indexing file, how much size should be the limit of searching? cheers and wait 4 reply. ++++++++++++++++++++++++++++++++++++++++++++++++++ hi,there, follow Coady siad, i set the length to max 2^31-1. But the search result still can't include what i want. simply, i convert the doc word to string array[] to analyze, one doc word has 79680 words include the space and any symbol. when i search certain word, it just return 300 count, actually it has more than 300 results. The same reason, when i search a word in back part of the doc, it also couldn't find. //////////////set the length idexwriter.SetMaxFieldLength(2147483647); ////////////////////search IndexSearcher searcher = new ndexSearcher(Program.Parameters["INDEX_LOCATION"].ToString()); Hits hits = searcher.Search(query); This is my code, as others same. I found that problem when i need to count every word hits in a doc. So i also found it couldn't search word in back part of doc. pls help me to find, is there any set searcher length somewhere? how u meet this problem.

• exec() in BeanShell macro causes jEdit to hang when it returns non-zero exit code

  - by rossmeissl

  I have a jEdit BeanShell macro that runs my Markdown files through Maruku when I save them: if (buffer.getMode().toString().equals("markdown")) { cmd = "C:\\Ruby\\bin\\maruku.bat -o " + buffer.getDirectory() + buffer.getName().replaceAll("markdown$", "html") + " " + buffer.getPath(); exec(cmd); } This works great when the Markdown file is valid. But if I've made a mistake, jEdit just waits around forever for the exec() call to "succeed," which it never will. When this happens, I have to kill jEdit's javaw.exe process and run Maruku manually from the command line to discover the error, e.g.: E:\bp\plan\supply_chain>maruku business_plan.markdown ___________________________________________________________________________ | Maruku tells you: +--------------------------------------------------------------------------- | Could not find ref_id = "17" for md_link(["17"],"17") | Available refs are [] +--------------------------------------------------------------------------- !C:/Ruby/lib/ruby/gems/1.8/gems/maruku-0.6.0/lib/maruku/errors_management.rb:49:in `maruku_error' !C:/Ruby/lib/ruby/gems/1.8/gems/maruku-0.6.0/lib/maruku/output/to_html.rb:716:in `to_html_link' !C:/Ruby/lib/ruby/gems/1.8/gems/maruku-0.6.0/lib/maruku/output/to_html.rb:970:in `send' !C:/Ruby/lib/ruby/gems/1.8/gems/maruku-0.6.0/lib/maruku/output/to_html.rb:970:in `array_to_html' !C:/Ruby/lib/ruby/gems/1.8/gems/maruku-0.6.0/lib/maruku/output/to_html.rb:961:in `each' \___________________________________________________________________________ Not creating a link for ref_id = "17". Then I restart jEdit, fix the error, and re-save the file, at which point the macro succeeds. How can I make my macro more resilient to either die helpfully (display Maruku's error output) or, at the very least, die silently so I don't have to kill jEdit?

• bash: listing files in date order, with spaces in filenames

  - by Jason Judge

  I am starting with a file containing a list of hundreds of files (full paths) in a random order. I would like to list the details of the ten latest files in that list. This is my naive attempt: ls -las -t `cat list-of-files.txt` | head -10 That works, so long as none of the files have spaces in, but fails if they do as those files are split up at the spaces and treated as separate files. I have tried quoting the files in the original list-of-files file, but the here-document still splits the files up at the spaces in the filenames. The only way I can think of doing this, is to ls each file individually (using xargs perhaps) and create an intermediate file with the file listings and the date in a sortable order as the first field in each line, then sort that intermediate file. However, that feels a bit cumbersome and inefficient (hundreds of ls commands rather than one or two). But that may be the only way to do it? Is there any way to pass "ls" a list of files to process, where those files could contain spaces - it seems like it should be simple, but I'm stumped.

• General Address Parser for Freeform Text

  - by Daemonic

  We have a program that displays map data (think Google Maps, but with much more interactivity and custom layers for our clients). We allow navigation via a set of combo boxes that prefill certain fields with a bunch of data (ie: Country: Canada, the Province field is filled in. Select Ontario, and a list of Counties/Regions is filled in. Select a county/region, and a city is filled in, etc...). While this guarantees accurate addresses, it's a pain for the users if they don't know where a street address or a city are located (ie, which county/region is kitchener in?). So we are looking at trying to do an address parser with a freeform text field. The user could enter something like this (similar to Google Maps, Bing Maps, etc...): 22 Main St, Kitchener, On And we could compartmentalize it into sections and do lookups on the data and get to the point they are looking for (or suggest alternatives). The problem with this is that how do we properly compartmentalize information? How do we break up the sections and find possible matches? I'm guessing we wouldn't be guaranteed that the user would enter data in a format we always expected (obviously). A follow up to this would be how to present the data if we don't find an exact match (or find multiple exact matches... two cities with the same street name in different counties, for example). We have a ton of data available in the mapping data (mapinfo tab format mostly). So we can do quick scans of street names, cities, states, etc. But I'm not sure about the best way to go about approaching this problem. Sure, using Google Maps would be nice, bue most of our clients are in closed in networks where outside access is not usually allowed and most aren't willing to rely on google maps (since it doesn't contain as much information as they need, such as custom map layers). They could, obviously, go to google and get the proper location then move to our software, but this would time consuming and speed of the process can be quite important.

• XElement vs Dcitionary

  - by user135498

  Hi All, I need advice. I have application that imports 10,000 rows containing name & address from a text file into XElements that are subsequently added to a synchronized queue. When the import is complete the app spawns worker threads that process the XElements by deenqueuing them, making a database call, inserting the database output into the request document and inserting the processed document into an output queue. When all requests have been processed the output queue is written to disk as an XML doc. I used XElements for the requests because I needed the flexibility to add fields to the request during processing. i.e. Depending on the job type the app might require that it add phone number, date of birth or email address to a request based on a name/address match against a public record database. My questions is; The XElements seems to use quite a bit of memory and I know there is a lot of parsing as the document makes its way through the processing methods. I’m considering replacing the XElements with a Dictionary object but I’m skeptical the gain will be worth the effort. In essence it will accomplish the same thing. Thoughts?

• What do I name this class whose sole purpose is to report failure?

  - by Blair Holloway

  In our system, we have a number of classes whose construction must happen asynchronously. We wrap the construction process in another class that derives from an IConstructor class: class IConstructor { public: virtual void Update() = 0; virtual Status GetStatus() = 0; virtual int GetLastError() = 0; }; There's an issue with the design of the current system - the functions that create the IConstructor-derived classes are often doing additional work which can also fail. At that point, instead of getting a constructor which can be queried for an error, a NULL pointer is returned. Restructuring the code to avoid this is possible, but time-consuming. In the meantime, I decided to create a constructor class which we create and return in case of error, instead of a NULL pointer: class FailedConstructor : public IConstructor public: virtual void Update() {} virtual Status GetStatus() { return STATUS_ERROR; } virtual int GetLastError() { return m_errorCode; } private: int m_errorCode; }; All of the above this the setup for a mundane question: what do I name the FailedConstructor class? In our current system, FailedConstructor would indicate "a class which constructs an instance of Failed", not "a class which represents a failed attempt to construct another class". I feel like it should be named for one of the design patterns, like Proxy or Adapter, but I'm not sure which.

• Working with a database

  - by Susan

  I have an existing program for a bank account, the user can create an account then withdraw or deposit money to the account. As a transaction is processed, labels are being used to show the current information such as (Beginning Balance, Transaction Fee, Withdrawal Amount, and Ending Balance). Now, I need to be able to keep track of the transactions being processed in a SQL database. I know how to add a database to the project and then set it up to display all of the data from the table in a gridview. This is assuming that I manually entered data into the table; however, the table should be blank when the program starts and as I process transactions, then the data should be written to the table. How do I bind my existing fields (labels) to a datatable and send the text to the table. The book that I have is all related to just displaying the data that is already in the table and I have been through a couple of tutorial online and they seem to be about the same subject. I haven't found anything on how to do what I am looking for. Can someone help me out here. I don't mind references to other websites that might have the answer. Thanks, Susan

• Setting ModerationInformation.Status from Approved back to pending removes

  - by Gavin Morgan

  Seeing if anyone else has had this problem and a resolution to it. I have a visual studio sequential workflow on a list (not a library) which does NOT use tasks, the approval process is done through the Approve/Reject OOTB buttons on the list item. The approval is a 2 stage approval, whereby if the 1st stage is completed (via clicking the Approve OOTB button), i reset the ModerationInformation.Status from Approved back to pending then send an email to the 2nd stage approver. My problem is, when i set the the ModerationInformation.Status back to Pending from Approved so there is never an approved version, the Creator loses permissions to view the item, and i get the "cannot find item" error from SharePoint for the person who created the item. The 1st and 2nd level approvers and anyone with approve rights CAN still see the item. Some more background information. the code i am using to update the moderationinformation is I get the properties from the workflow event and get a hook into the listitem properties.Item.ModerationInformation.Status = SPModerationStatusType.Pending; properties.Item.Update(); can anyone help.

Exception in thread "main" java.lang.Error: Unresolved compilation problem: The method nextToken() is undefined for the type String at testread.getEngineLoad(testread.java:243) at testread.readFile(testread.java:149) at testread.main(testread.java:119) so how do I get this to work? It seems to pass the variable, but nothing after the . works.

• Issue with 'Hello Android' tutorial

  - by Mike Needham

  I am brand new to Eclipse and Android, but somewhat familiar with Java. That having been said, I tried to follow the 'Hello Android' tutorial from the developer site using the latest Eclipse (Galieo) and the 2.1 Android SDK, I am on a Macintosh running Snow Leopard (OS X 10.6). I have a default virtual device (though my target is actually for phones like my own HTC Incredible which has the snapdragon processor and of course all the latest accoutrement in smart phones. Everything seemed to go okay until I went to RUN>RUN and then selected 'Android Application'. My computer spins it's wheels for a while and then I see two errors. I have pasted the output below: [2010-05-04 01:53:46 - HelloAndroid] ------------------------------ [2010-05-04 01:53:46 - HelloAndroid] Android Launch! [2010-05-04 01:53:46 - HelloAndroid] adb is running normally.

Apps should cease use of QuickDraw and move to Quartz. [2010-05-04 01:54:23 - HelloAndroid] emulator-5554 disconnected! Cancelling 'com.example.helloandroid.HelloAndroid activity launch'! I never do see the text in the emulator and the emulator crashes with a message about it quitting unexpectedly. The actual code is line by line from the tutorial and I have never been able to get to the XML part yet. I am not sure what is wrong with my environment setup or if it is just an incompatibility with Snow Leopard? I would REALLY appreciate any help in resolving this as I am very interested in developing on this platform. Thank-you, Mike N Lawrence, Kansas

• Filtering most out of XML with XSL?

  - by Gnudiff

  I need to transform a lot of XML files (Fedora export) into a different kind of XML. Trying to do it with XSL stylesheets and checking with the msxsl transformer. Supposedly I have xml file like this (assuming there are actually other nodes inside AAA, OBJ, amd all other nodes), Source.XML: <DOC> <AAA> <STUFF>example</STUFF> <OBJ> <OBJVERS id="A1" CREATED="2008-02-18T13:28:08.245Z"/> <OBJVERS id="A2" CREATED="2008-02-19T10:42:41.965Z"/> <OBJVERS id="A13" CREATED="2009-03-16T12:43:11.703Z"/> </OBJ> </AAA> <FFF/> <GGG/> <DDD> <FILE /> </DDD> </DOC> Which I need to look something like this (Target.XML): <MYOBJ> <ELEM>contents of OBJVERS with the biggest id OR creation date (whichever is easier to do) go here</ELEM> <IMAGE> contents of <FILE> node go here</IMAGE> </MYOBJ> The main problem that I have is that since I am new to XSL (and for this particular task do not have enough time to learn it properly) is that I can't understand how to tell XSL processor not to process anything else, I keep getting output from , for example. Update: basically, I solved this problem meanwhile. I will post my own answer and close the question. Update2: OK, Andrew's answer works, too, so I am just accepting it. :)

• Efficient Method for Preventing Hotlinking via .htaccess

  - by Michael Robinson

  I need to confirm something before I go accuse someone of ... well I'd rather not say. The problem: We allow users to upload images and embed them within text on our site. In the past we allowed users to hotlink to our images as well, but due to server load we unfortunately had to stop this. Current "solution": The method the programmer used to solve our "too many connections" issue was to rename the file that receives and processes image requests (image_request.php) to image_request2.php, and replace the contents of the original with <?php header("HTTP/1.1 500 Internal Server Error") ; ?> Obviously this has caused all images with their src attribute pointing to the original image_request.php to be broken, and is also the wrong code to be sending in this case. Proposed solution: I feel a more elegant solution would be: In .htaccess If the request is for image_request.php Check referrer If referrer is not our site, send the appropriate header If referrer is our site, proceed to image_request.php and process image request What I would like to know is: Compared to simply returning a 500 for each request to image_request.php: How much more load would be incurred if we were to use my proposed alternative solution outlined above? Is there a better way to do this? Our main concern is that the site stays up. I am not willing to agree that breaking all internally linked images is the best / only way to solve this. I refuse to tell our users that because of something WE changed they must now manually change the embed code in all their previously uploaded content.
