• Translate a webpage in PHP

  - by Rob

  I'm looking to translate a webpage in PHP 5 so I can save the translation and make it easily accessible via mydomain.com/lang/fr/category/article.html rather than users having to go through google translate. I've found various easy ways to translate text via CURL, however what i'd really like to be able to do is translate an entire webpage but obviously ignore the tags. The problem is that Google Translate messes up all the HTML tags, class names etc Does anyone know of a php class that can translate an entire webpage whilst ignoring the tags? I'm guessing it may be possible via advanced regular expressions or something like that, but i'm not sure. I can't just curl Google's response as i'll have all the extra JS that they put in. Any ideas?

• Can I use UIPerformance grails plugin and host my static resources in another domain?

  - by fabien7474

  The UIPerfomance plugin is an easy way to speed up your web pages by applying some of the best practices rules from Yahoo performance team (like minifying, setting a far-future expires header, versioned images...) Unfortunately I didn't find a way to store the static resources in a location outside of the webapplication which has his own advantages ( smaller WAR sizes, better optimize cookieless server, static resources served faster by a highly optimized native httpd, no need to redeploy WAR when updating static resources..). So my question is: is it possible to use this great plugin with static resoures stored outside the web application? And if yes, how?

• Treat multiple IEnumerable objects as a single IEnumerable

  - by MainMa

  Hi, My question seems to be something easy, but I can't figure it out. Let's say I have a "root" IEnumerable of objects. Each object has IEnumerable of strings. How can I obtain a single IEnumerable of those strings? A possible solution is to do: public IEnumerable<string> DoExample() { foreach (var c in rootSetOfObjects) { foreach (var n in c.childSetOfStrings) { yield return n; } } } But maybe there is a magic solution with Linq?

• Which web Tier Framework for a public commercial website with heavy load ?

  - by Maxime ARNSTAMM

  Hello everyone, As a part of an enterprise architecture exercise, i need to find a java-based framework filling these constraints : heavy (i think) load : 5000 concurrent connections widely known : can't be too exotic, the contractors would be too high priced. relatively easy to use : developpement time must be reasonnable must be as compliant as possible with the css/html layout produced by a designer Must look like "web 2.0" from the marketing point of view. What i learned from my limited experience is : jsf : 1, don't know. 2, 3 ok. 4 not ok (at least not without huge effort) wicket : 1, not really. 2, 3 and 4 ok. gwt : 1, don't know. 2, 3 ok. 4 not ok (but more ok than jsf) others : not really "web 2.0" or not really known I'm really junior, so my ideas about those frameworks are probably wrong, that's why i come to you, stackoverflowees. Thanks for helping :)

• regular expression search in python

  - by Richard

  Hello all, I am trying to parse some data and just started reading up on regular Expressions so I am pretty new to it. This is the code I have so far String = "MEASUREMENT 3835 303 Oxygen: 235.78 Saturation: 90.51 Temperature: 24.41 DPhase: 33.07 BPhase: 29.56 RPhase: 0.00 BAmp: 368.57 BPot: 18.00 RAmp: 0.00 RawTem.: 68.21" String = String.strip('\t\x11\x13') String = String.split("Oxygen:") print String[1] String[1].lstrip print String[1] What I am trying to do is to do is remove the oxygen data (235.78) and put it in its own variable using an regular expression search. I realize that there should be an easy solution but I am trying to figure out how regular expressions work and they are making my head hurt. Thanks for any help Richard

• English dictionary as txt or xml file with support of synonyms

  - by Simon

  Can someone point me to where I can download English dictionary as a txt or xml file. I am building a simple app for myself and looking for something what I could start using immediately without learning complex API. Support for synonyms would be great, that is it should be easier to retrieve all the synonyms for particular word. It would be absolutely fantastic if dictionary would be listing British and American spelling of the words where they are differ. Even if it would be small dictionary (few 000's words) that's ok, I only need it for small project. I even would be willing to buy one if the price is reasonable, and dictionary is easy to use - simple xml wold be great. Any directions please.

• What is the equivalent to IScriptControl for Web.UI.Page?

  - by Jeff Dege

  We've been using IScriptControl to tie javascript objects to our UserControls and ServerControls, and it's worked fine. The problem is that ASP.NET seems to provide no method to tie a javascript object to a Page. Up to now, we've been putting plain functions in the global namespace, but I am developing a serious allergy to that practice. It'd be easy enough to wrap our functions into a javascript class, and to include the javascript file on the page, but how to instantiate the object, how to reference it from callback events, and how to pass data to it from the code-behind, I haven't figured out. Or rather, the methods we've been using up to now (hidden fields, emitted javascript strings, etc.), really bug me. Anyone have better ideas?

• Replay attacks for HTTPS requests

  - by MatthewMartin

  Let's say a security tester uses a proxy, say Fiddler, and records an HTTPS request using the administrator's credentials-- on replay of the entire request (including session and auth cookies) the security tester is able to succesfully (re)record transactions. The claim is that this is a sign of a CSRF vulnerability. What would a malicious user have to do to intercept the HTTPS request and replay it? It this a task for script kiddies, well funded military hacking teams or time-traveling-alien technology? Is it really so easy to record the SSL sessions of users and replay them before the tickets expire? No code in the application currently does anything interesting on HTTP GET, so AFAIK, tricking the admin into clicking a link or loading a image with a malicious URL isn't an issue.

• Delphi component or library to display mathematical expressions

  - by Svein Bringsli

  I'm looking for a simple component that displays mathematical expressions in Delphi. When I started out I thought it would be easy to find something on the net, but it turns out it was harder than anticipated. There are lots and lots of components that will parse mathematical expressions, but few (none?) that will display them. Ideally I would like a component as simple as a TLabel, where I could set the caption to some expression and it would be displayed correctly, but some sort of library that let's me draw expressions to a canvas would also be sufficient for my needs. Update: I'm not talking about plotting graphs of functions or something like that. I want to display (for instance) (X^2+3)/X like this:

• Making change recursively: How do I modify my algorithm to print all combinations?

  - by cb

  I have an algorithm that recursively makes change in the following manner: public static int makeChange(int amount, int currentCoin) { //if amount = zero, we are at the bottom of a successful recursion if (amount == 0){ //return 1 to add this successful solution return 1; //check to see if we went too far }else if(amount < 0){ //don't count this try if we went too far return 0; //if we have exhausted our list of coin values }else if(currentCoin < 0){ return 0; }else{ int firstWay = makeChange(amount, currentCoin-1); int secondWay = makeChange(amount - availableCoins[currentCoin], currentCoin); return firstWay + secondWay; } } However, I'd like to add the capability to store or print each combination as they successfully return. I'm having a bit of a hard time wrapping my head around how to do this. The original algorithm was pretty easy, but now I am frustrated. Any suggestions? CB

• Teamcity NTLM Authentication change - admin user lost in transition

  - by hawkeye

  I've switched in teamcity from using basic authentication to using NTLM, on an existing installation. This works fine, except that the admin user didn't have a corresponding NT account, and so doesn't work on the NTLM configuration. (It is easy to roll back, so it is not a stress). My question is - what is the command to set a user to admin manually - ie modifying the database? (like this: TeamCity forgotten admin password - where to look?) but changing the role of a user to global system administrator.

• Ruby Methods: how to return an usage string when insufficient arguments are given

  - by Shyam

  Hi, After I have created a serious bunch of classes (with initialize methods), I am loading these into IRb to test each of them. I do so by creating simple instances and calling their methods to learn their behavior. However sometimes I don't remember exactly what order I was supposed to give the arguments when I call the .new method on the class. It requires me to look back at the code. However, I think it should be easy enough to return a usage message, instead of seeing: ArgumentError: wrong number of arguments (0 for 9) So I prefer to return a string with the human readable arguments, by example using "puts" or just a return of a string. Now I have seen the rescue keyword inside begin-end code, but I wonder how I could catch the ArgumentError when the initialize method is called. Thank you for your answers, feedback and comments!

• Core dump utility for .NET

  - by Dave

  In my past life as a COBOL mainframe developer I made extensive use of a tool called Abendaid which, in the event of an exception, would give me a complete memory dump including a formatted list of every variable in memory as well as a complete stack trace of the program with the offending statement highlighted. This made pinpointing the cause of an error much simpler and saved a lot of step-through debugging and/or trace statements. Now I've made the transition to C# and .NET web development I find that the information provided by ASP.NET only tells half the story, giving me a stack trace, but not any of the variable or class information. This makes debugging more difficult as you then have to run the process again with the debugger to try and reproduce the error, not easy with intermittent errors or with assemblies that run under the likes of SQL Server or CRM. I've looked around quite a lot for something that does this but I can't find anything obvious. Does anyone have any idea if there is one, or if not, what I'd need to start with in order to write one?

• Renaming Functions during runtime in PHP.

  - by The Rook

  In PHP 5.3 is there a way to rename a function or "hook" a function. There is the rename_function() within "APD" which has been broken since ~2004. If you try and build it on PHP 5.3 you'll get this error: 'struct _zend_compiler_globals' has no member named 'extended_info' This is a really easy error to fix, just change this line: GC(extended_info) = 1; to CG(compiler_options) |= ZEND_COMPILE_EXTENDED_INFO; I modified my php.ini and the APD shows up in my phpinfo() as it should. However when i call rename_function() the PHP page doesn't load and I get a segmentation fault in my /var/log/apache2/error.log. Is there anyway to fix APD to work with a modern version of PHP? Or is there another method to rename functions? Why on earth is vital feature not in php!??!?! (Gotta love python :)

• Create link on page w/ web address stored in database

  - by RememberME

  This seems like it should be easy, but I can't seem to figure it out. All of my google searches lead me to linking to databases which isn't what I want to do. I'm a complete web development newb. I've roughly followed the NerdDinner tutorial in creating my web app. One of my stored fields is a web address. On the Index and Details pages, when I display the info from my record, I want the web address to be a clickable link to the website. It's currently displayed as: <%= Html.Encode(Model.Subcontract.company1.website) %>

• jQuery Toggle Cookie Support

  - by hell0w0rld

  I'm trying to implement the jQuery Cookie plugin into my slide toggle script, but so far haven't been successful. Here's my code (without any cookie implementation): jQuery: $(document).ready(function() { $('a.toggle').click(function() { var id = $(this).attr('name'); $('#module' + id).slideToggle('fast'); $('a.toggle[name='+id+']').toggle(); return false; }); }); HTML: <a class="toggle" name="1" href="#">- Hide</a> <a class="toggle hidden" name="1" href="#">+ Show</a> <div id="module1"><p>Hello World</p></div> Anyone know if it's easy enough to implement the jQuery Cookie plugin into my existing code so it remembers the open/closed state? Thank you.

• Simple way to use Foreign Key values for sorting?

  - by Brian Rizzo

  Disclaimer: I jumped to C# 2008 recently and SubSonic 3 (3.0.0.4) at the same time. I haven't used Linq for much of anything in the past. Is there an easy way to use the foreign key display value for sorting, rather than the FK Id (which is numeric)? I've added a new Find method in my ActiveRecord.tt to help with sorting based on a string field name but after doing some testing I realized that even though its working as it should be, I am not handling foreign key fields at all (they are just sorting by their value). Even if I need to change how I am accessing the data it is early enough in the project to do that. Just looking for suggestions.

• How can I translate my programmatic WCF configuration into app.config

  - by ofer

  Hi, I have an self hosted WCF server with hard coded configurations. the server worked fine until I tried to implement some new functionality. the new setting did not work (urrr.... ) and I find it hard to locate where are the problems in my code. instead of digging inside the code, I thought about different approach: Is there any way to dump those hard coded WCF configuration (the entire ) into app.config like text file after all configurations are loaded? this will enable me to have a easy global view of the entire settings .. mmm .. .by the way, does anyone know a way that will do the translation to the opposite direction? config to code. Any advice will be welcomed! ofer

• WiX, how to prevent files from uninstalling though we forgot to set Permanent="yes"

  - by Doc Brown

  We have a product installer created with Wix, containing a program package ("V1") and some configuration files. Now, we are going to make a major upgrade with a new product code, where the old version of the product is uninstalled and "V2" is installed. What we want is to save one of the configuration files from uninstalling, since it is needed for the V2, too. Unfortunately, we forgot to set the Permanent="yes" option when we delivered V1 (read this question for more information). Here comes the question: is there an easy way of preventing the uninstall of the file anyhow? Of course, we could add a custom action to the script to backup the file before uninstallation, and another custom action to restore it afterwards, but IMHO that seems to be overkill for this task, and might interfere with other parts of the MSI registration process.

• (My)SQL performance: updating one field vs many unneccesary fields

  - by changokun

  i'm processing a form that has a lot of fields for a user who is editing an existing record. the user may have only changed one field, and i would typically do an update query that sets the values of all the fields, even though most of them don't change. i could do some sort of tracking to see which fields have actually changed, and only update the few that did. is there a performance difference between updating all fields in a record vs only the one that changed? are there other reasons to go with either method? the shotgun method is pretty easy...

• Using ManualResetEvent to wait for multiple Image.ImageOpened events

  - by umlgorithm

  Dictionary<Image, ManualResetEvent> waitHandleMap = new Dictionary<Image, ManualResetEvent>(); List<Image> images = GetImagesWhichAreAlreadyInVisualTree(); foreach (var image in images) { image.Source = new BitmapImage(new Uri("some_valid_image_url")); waitHandleMap.Add(image, new ManualResetEvent(false)); image.ImageOpened += delegate { waitHandleMap[image].Set(); }; image.ImageFailed += delegate { waitHandleMap[image].Set(); }; } WaitHandle.WaitAll(waitHandleMap.Values.ToArray()); WaitHandle.WaitAll blocks the current UI thread, so ImageOpened/ImageFailed events would never get fired. Could you suggest me an easy workaround to wait for the multiple ui events?

• Named arguments in Mathematica.

  - by dreeves

  What's the best/canonical way to define a function with optional named arguments? To make it concrete, let's create a function foo with named arguments a, b, and c, which default to 1, 2, and 3, respectively. For comparison, here's a version of foo with positional arguments: foo[a_:1, b_:2, c_:3] := bar[a,b,c] Here is sample input and output for the named-arguments version of foo: foo[] --> bar[1,2,3] foo[b->7] --> bar[1,7,3] foo[a->6, b->7, c->8] --> bar[6,7,8] It should of course also be easy to have positional arguments before the named arguments.

• Why no ArgumentEmptyException in .NET ?

  - by Andrei Rinea

  I am beginning to think I am doing something wrong. I mean they did place System.String.IsNullOrWhitespace finally but no ArgumentEmptyException class. public FilterItem(string name, IEnumerable<string> extensions) { if (string.IsNullOrWhiteSpace(name)) { throw new ArgumentNullException("name"); } if (extensions == null) { throw new ArgumentNullException("extensions"); } if (extensions.Count() == 0) { throw new ArgumentOutOfRangeException("extensions"); } this.Name = name; this.Extensions = extensions; } throwing an ArgumentOutOfRangeException feels unnatural. Also an instance of ArgumentException is too general in my opinion. It's easy to me to create a new exception class call it this way and have it over with. What bugs me is that it's not in the BCL/FCL and I am beginning to think there's a good reason not to have it. Should there be one?

• Get the SEF URLs for articles in joomla

  - by DMin

  Hi, I use no-editor in joomla with SEF urls enabled. With no SEF enabled its easy to know the URL by just getting the ID of the article something like : Article 1 would be : http://www.abc.com/j15/index.php?option=com_content&view=article&id=1&Itemid=1 Now if I have SEF switched on I would get urls that look like: http://www.abc.com/j15/the-content.html Is there a way inside joomla where I can findout what the SEF URL for a particular page is? Currently I add these articles to a menu, then from the front-end I get the SEF URL and then use it. I know the process is a little dumb but I want to find-out if there is a better way inside joomla where you can get the SEF URL(using no-editor). Thanks! :)

• How can I dynamically clear all controls in a user control?

  - by Michael

  Is it possible to dynamically (and generically) clear the state of all of a user control's child controls? (e.g., all of its TextBoxes, DropDrownLists, RadioButtons, DataGrids, Repeaters, etc -- basically anything that has ViewState) I'm trying to avoid doing something like this: foreach (Control c in myUserControl.Controls) { if (c is TextBox) { TextBox tb = (TextBox)c; tb.Text = ""; } else if (c is DropDownList) { DropDownList ddl = (DropDownList)c; ddl.SelectedIndex = -1; } else if (c is DataGrid) { DataGrid dg = (DataGrid)c; dg.Controls.Clear(); } // etc. } I'm looking for something like this: foreach (Control c in myUserControl.Controls) c.Clear(); ...but obviously that doesn't exist. Is there any easy way to accomplish this dynamically/generically?
