• rsync over ssh is not working anymore, while ssh itself is working fine (Write failed: broken pipe)

  - by brazorf

  This issue started happening after i changed router. This is the scenario: Windows7 Host Ubuntu 10.04 Guest (VirtualBox) Ubuntu 10.04 remote server What i used to do is run a very basic rsync command: rsync -avz --delete /local/path/ username@host:/path/to/remote/directory This worked perfect until i did change adsl provider, and i changed router aswell: now, this happens: rsync on Ubuntu Guest is not working anymore (to any random server), if using this new router rsync on Ubuntu Guest is WORKING, if i switch back to old router i tried a new virtual box ubuntu install, and the command is WORKING with both the routers So, the not-working-combo is oldUbuntu + newRouter. To get things worst, i can state that (on the not-working ubuntu) i ping the remote host plain ssh connection to the remote host is working fine (i can auth, connect, and do stuff on the remote host) scp is NOT working (this is just a further thing i tried) This is the console output of the execution, with ssh verbose set to vvvv: root@client:~# rsync -ae 'ssh -vvvv' /root/test-rsync/

• How to save some values from an array in a controller in Rails?

  - by Alfred Nerstu

  I've got a links array that I'm saving to a database. The problem is that the records aren't saved in the order of the array ie links[1] is saved before links[2] and so on... This is a example from the view file: <p> <label for="links_9_label">Label</label> <input id="links_9_name" name="links[9][name]" size="30" type="text" /> <input id="links_9_url" name="links[9][url]" size="30" type="text" /> </p> And this is my controller: def create @links = params[:links].values.collect { |link| @user.links.new(link) } respond_to do |format| if @links.all?(&:valid?) @links.each(&:save!) flash[:notice] = 'Links were successfully created.' format.html { redirect_to(links_url) } else format.html { render :action => "new" } end end end Thanks in advance!

• How to write a Custom DesignerSerializer for an class used by a Activity (WF)

  - by Stefan Steinegger

  I have a type which is used in a WF activity. It should be serialized. It doesn't work out of the box, most probably because of the private setters in that type. I'm not sure if this is the correct way, but I tried to write my own serializer and declared it on my class. [DesignerSerializer( typeof(FooDesignerSerializer), // my custom serializer typeof(WorkflowMarkupSerializer))] public class Foo { public Foo(int value, string name { // ... } public int Value { get; private set; } public string Name { get; private set; } } Is this the easiest way to get it serialized? How do I write this serializer? That's what I got so far: public class FooDesignerSerializer : WorkflowMarkupSerializer { protected override string SerializeToString( WorkflowMarkupSerializationManager serializationManager, object value) { // how to create a valid / XOML-like string? } }

• How does the method overload resolution system decide which method to call when a null value is passed?

  - by Joan Venge

  So for instance you have a type like: public class EffectOptions { public EffectOptions ( params object [ ] options ) {} public EffectOptions ( IEnumerable<object> options ) {} public EffectOptions ( string name ) {} public EffectOptions ( object owner ) {} public EffectOptions ( int count ) {} public EffectOptions ( Point point ) {} } Here I just give the example using constructors but the result will be the same if they were non-constructor methods on the type itself, right? So when you do: EffectOptions options = new EffectOptions (null); which constructor would be called, and why? I could test this myself but I want to understand how the overload resolution system works (not sure if that's what it's called).

• IE 8: Object Expected for Every Javascript Function

  - by Yetkin EREN

  Hi; Moz say's everything is ok! IE say's object expected everywhere.. for example this my make a box function (in all.js file); function kutuyap(Eid,iduzan,text,yer,ekle){ var div; if (document.createElement && (div = document.createElement('div'))) { div.name = div.id = Eid+iduzan; document.getElementById(yer).appendChild(div); } //$('#'+yer).append("<div id="+Eid+iduzan+"></div>") $('#'+Eid+iduzan).addClass("minikutu"); $('#'+Eid+iduzan).html("&nbsp;"+text+'<span id='+Eid+'y'+iduzan+' class="yokedici">X</span>'); $("#"+Eid+'y'+iduzan).attr("onclick","kutusil('"+Eid+"y"+iduzan+"','"+iduzan+"','"+ekle+"');"); $('#'+ekle).val($('#'+ekle).val()+Eid+'-'); } and after that i call function like this; HTML; <select name="Mturs" class="inputs" id="Mturs"> <option value="0" selected="selected">Choise One</option> <option value="4">Pop</option> <option value="3">Pop-Rock </option> <option value="5">Rock (Yabanci)</option> </select> <input name="secMtur" id="secMtur" value="" type="hidden"> <script> $('#Mturs').live('change', function() { $('#Mturs :selected').each(function (i) { if ( $('#Mturs :selected').val() != 0 ) { secMturde=$('#secMtur').val().indexOf($('#Mturs :selected').val()+'-'); splitter=$('#secMtur').val().split("-") if(splitter.length<=12){ if (secMturde<0) { kutuyap($('#Mturs :selected').val(),'mtur',$(this).html(),'divmtur','secMtur'); }else{ alert("Choisen before") } }else{ alert("Max limit is 12 !") } } }); }); </script> sory for my realy bad english.. edit: and i have this tags; <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.1/jquery.min.js"> </script> <script type="text/javascript" src="alljs.js"></script>

• jQuery's blur() and selector problem

  - by matthewayinde

  I'm trying to create a new div each time a text field contained in the last div loses focus, but a new div is added only when the text field in the first div loses focus (instead of the last)... Please I need help urgently. Thanks a lot. Here's my code: $(function() { $(':text:last').blur(function() { $('<div class="line"><span>data: </span><input type="text"/></div>') .appendTo($('#lineStack')); }); }); HTML: <div id="lineStack"> <div class="line"> <span>data: </span><input type="text" /> </div> </div>

• Dynamic data-entry value store

  - by simendsjo

  I'm creating a data-entry application where users are allowed to create the entry schema. My first version of this just created a single table per entry schema with each entry spanning a single or multiple columns (for complex types) with the appropriate data type. This allowed for "fast" querying (on small datasets as I didn't index all columns) and simple synchronization where the data-entry was distributed on several databases. I'm not quite happy with this solution though; the only positive thing is the simplicity... I can only store a fixed number of columns. I need to create indexes on all columns. I need to recreate the table on schema changes. Some of my key design criterias are: Very fast querying (Using a simple domain specific query language) Writes doesn't have to be fast Many concurrent users Schemas will change often Schemas might contain many thousand columns The data-entries might be distributed and needs syncronization. Preferable MySQL and SQLite - Databases like DB2 and Oracle is out of the question. Using .Net/Mono I've been thinking of a couple of possible designs, but none of them seems like a good choice. Solution 1: Union like table containing a Type column and one nullable column per type. This avoids joins, but will definitly use a lot of space. Solution 2: Key/value store. All values are stored as string and converted when needed. Also use a lot of space, and of course, I hate having to convert everything to string. Solution 3: Use an xml database or store values as xml. Without any experience I would think this is quite slow (at least for the relational model unless there is some very good xpath support). I also would like to avoid an xml database as other parts of the application fits better as a relational model, and being able to join the data is helpful. I cannot help to think that someone has solved (some of) this already, but I'm unable to find anything. Not quite sure what to search for either... I know market research is doing something like this for their questionnaires, but there are few open source implementations, and the ones I've found doesn't quite fit the bill. PSPP has much of the logic I'm thinking of; primitive column types, many columns, many rows, fast querying and merging. Too bad it doesn't work against a database.. And of course... I don't need 99% of the provided functionality, but a lot of stuff not included. I'm not sure this is the right place to ask such a design related question, but I hope someone here has some tips, know of any existing work, or can point me to a better place to ask such a question. Thanks in advance!

• How to determine whether a class has a particular templated member function?

  - by Aozine

  I was wondering if it's possible to extend the SFINAE approach to detecting whether a class has a certain member function (as discussed here: "Is there a Technique in C++ to know if a class has a member function of a given signature?" http://stackoverflow.com/questions/87372/is-there-a-technique-in-c-to-know-if-a-class-has-a-member-function-of-a-given-s ) to support templated member functions? E.g. to be able to detect the function foo in the following class: struct some_class { template < int _n > void foo() { } }; I thought it might be possible to do this for a particular instantiation of foo, (e.g. check to see if void foo< 5 >() is a member) as follows: template < typename _class, int _n > class foo_int_checker { template < typename _t, void (_t::*)() > struct sfinae { }; template < typename _t > static big test( sfinae< _t, &_t::foo< _n > > * ); template < typename _t > static small test( ... ); public: enum { value = sizeof( test< _class >( 0 ) ) == sizeof( big ) }; }; Then do foo_int_checker< some_class, 5 >::value to check whether some_class has the member void foo< 5 >(). However on MSVC++ 2008 this always returns false while g++ gives the following syntax errors at the line test( sfinae< _t, &_t::foo< _n > > ); test.cpp:24: error: missing `>' to terminate the template argument list test.cpp:24: error: template argument 2 is invalid test.cpp:24: error: expected unqualified-id before '<' token test.cpp:24: error: expected `,' or `...' before '<' token test.cpp:24: error: ISO C++ forbids declaration of `parameter' with no type Both seem to fail because I'm trying to get the address of a template function instantiation from a type that is itself a template parameter. Does anyone know whether this is possible or if it's disallowed by the standard for some reason? EDIT: It seems that I missed out the ::template syntax to get g++ to compile the above code correctly. If I change the bit where I get the address of the function to &_t::template foo< _n > then the program compiles, but I get the same behaviour as MSVC++ (value is always set to false). If I comment out the ... overload of test to force the compiler to pick the other one, I get the following compiler error in g++: test.cpp: In instantiation of `foo_int_checker<A, 5>': test.cpp:40: instantiated from here test.cpp:32: error: invalid use of undefined type `class foo_int_checker<A, 5>' test.cpp:17: error: declaration of `class foo_int_checker<A, 5>' test.cpp:32: error: enumerator value for `value' not integer constant where line 32 is the enum { value = sizeof( test< _class >( 0 ) ) == sizeof( big ) }; line. Unfortunately this doesn't seem to help me diagnose the problem :(. MSVC++ gives a similar nondescript error: error C2770: invalid explicit template argument(s) for 'clarity::meta::big checker<_checked_type>::test(checker<_checked_type>::sfinae<_t,&_t::template foo<5>> *)' on the same line. What's strange is that if I get the address from a specific class and not a template parameter (i.e. rather than &_t::template foo< _n > I do &some_class::template foo< _n >) then I get the correct result, but then my checker class is limited to checking a single class (some_class) for the function. Also, if I do the following: template < typename _t, void (_t::*_f)() > void f0() { } template < typename _t > void f1() { f0< _t, &_t::template foo< 5 > >(); } and call f1< some_class >() then I DON'T get a compile error on &_t::template foo< 5 >. This suggests that the problem only arises when getting the address of a templated member function from a type that is itself a template parameter while in a SFINAE context. Argh!

• How can I make XOR work for logical matrix in MATLAB?

  >> XOR(X,X) ??? Undefined function or method 'XOR' for input arguments of type 'logical'. Why XOR can't be used for logical matrix?

• Selenium: How to enter white space as the value of a text field?

  - by Andrew

  I have a form text field that is being populated with a default value. I would like to clear the value and enter white space to assert that the expected validation occurs. I am using Selenium RC and the PHPUnit Selenium extension. How can I achieve this? Note: I have already tried doing these, but they do not work: $this->type('FirstName', " "); //spaces $this->type('FirstName', "\t"); //tab character They clear the value from the field, but they do not enter the white space into the field.

• Using jQuery to echo text

  - by susmits

  Is it possible to use jQuery to echo text in place of a script tag? More precisely, is there a way to accomplish <script type="text/javascript"> document.write("foo"); </script> ... without the use of document.write? I am not happy about using document.write after reading this. I am aware that I could alternatively do this: <span id="container"></span> <script type="text/javascript"> $("#container").text("foo"); </script> However, I'm interested to see if there's a way to do it without using a container element, preferably using jQuery. Thanks in advance!

• SqlParameter contructor compiler overload choice

  - by Ash

  When creating a SqlParameter (.NET3.5) or OdbcParameter I often use the SqlParameter(string parameterName, Object value) constructor overload to set the value in one statement. When I tried passing a literal 0 as the value paramter I was initially caught by the C# compiler choosing the (string, OdbcType) overload instead of (string, Object). MSDN actually warns about this gotcha in the remarks section, but the explanation confuses me. Why does the C# compiler decide that a literal 0 parameter should be converted to OdbcType rather than Object? The warning also says to use Convert.ToInt32(0) to force the Object overload to be used. It confusingly says that this converts the 0 to an "Object type". But isn't 0 already an "Object type"? The Types of Literal Values section of this page seems to say literals are always typed and so inherit from System.Object. This behavior doesn't seem very intuitive given my current understanding? Is this something to do with Contra-variance or Co-variance maybe?

• Embedded strongly-typed views with ASP.NET MVC

  - by Brian Vallelunga

  I'm working on a plugin-type of system for ASP.NET MVC that loads views from an embedded assembly. I have created a VirtualPathProvider that does the work of retrieving out of the assembly. Everything is working fine except for strongly-typed views. Whenever I try to load one of those, I get an exception of: Could not load type 'System.Web.Mvc.ViewPage'. The problem is that there is no Web.config file under the Views folder. Well, actually there is, but the system doesn't seem to want to read the embedded version. If I manually create the file under the corresponding directory in the web app, everything is fine. This isn't an acceptable workaround however, as each plugin would need its own file in its own specific directory. Does anyone know how I might get ASP to read the embedded Web.config file? Thanks, Brian

• Drupal Views how to filter items overlapping a date range

  - by Marcos Buarque

  Hi, in Drupal I have used CCK to add a datetime field to my custom data type. It inserts start date and end date fields. That is what I want. Now, I want Views to filter and show only the items that have the daterange (start date and end date) overlapping today's date. Any ideas on how to set it up on Views? What I think is strange is that the date fields of my custom content type don't seem to appear on the Views list when I am trying to add a filter. Thanks.
