• Rails, making certain multiparameter attributes optional?

  - by Joseph Silvashy

  Is there a method already part of Rails for making certain parameters option when part of a multiparameter attribute, for example say I'm prompting a user for their birthday, when saved the has may look like this: "birthday(2i)"=>"8", "birthday(3i)"=>"17", "birthday(1i)"=>"1980"}, ... But the issue arises when say I want to allow the user to just provide their month and day, making the year optional, how would this work being a datetime object, I'm assuming you can't do this as a date object... but any ideas would be helpful. Happy new year.

• Best way to parse XMPP-like XML streams?

  - by codethief

  I am working on a server application which receives data over a TCP socket in an XMPP-like XML format, i.e. every child of the <root> element essentially represents one separate request (stanza). The connection is closed as soon as </root> is received. I do know that I must use a stream parser like SAX, somehow. Though, for convenience, I'd prefer to have a tree-like interface to access each stanza's child elements. (The data sent with every request is not large so I think it makes sense to read each stanza as a whole.) What's the best way to realize that in Python (preferably v3)? This is the code I'd like to build it in. Feel free to point me in a totally different direction to solve this issue. import socketserver import settings class MyServer(socketserver.ThreadingMixIn, socketserver.TCPServer): pass class MyRequestHandler(socketserver.StreamRequestHandler): def handle(self): pass if __name__ == '__main__': server = MyServer((settings.host, settings.port), MyRequestHandler) server.serve_forever()

• Is it possible to autocomplete fields in Sharepoint with user info?

  - by Antoine

  Hi, I'm in charge of a Sharepoint collection, and a user asks this. Is it possible that when a user creates an item, some fields are automatically filled with some info, such as email address and location? Authentication uses Active Directory, so every user is identified when using Sharepoint. The only issue is that, being in a big corporate company, I don't have any access to the server, so it must be feasible through configuration of said site/list or using Sharepoint Designer, but I can't and won't be allowed to deploy anything server side. Any idea?

• Android Dropdown (Select) CSS

  - by roguepixel

  I'm currently writing some stylesheets for mobile browsers and have come across a strange issue in the Android browser. When changing the font-size CSS attribute of a text box the box gets bigger to accomodate the larger text. Doing this on a select box however does not change the size of the select box, but the text still gets larger (actually overlapping the top and bottom of the rendered form element). Can anyone tell me if it's possible to increase the height of select boxes in the Android browser. Or if not point me in the direction of a list of CSS attributes that can be applied to them. Thanks.

• Rails object inheritence with belongs_to

  - by Rabbott

  I have a simple has_many/belongs_to relationship between Report and Chart. The issue I'm having is that my Chart model is a parent that has children. So in my Report model I have class Report < ActiveRecord::Base has_many :charts end And my Chart model is a parent, where Pie, Line, Bar all inherit from Chart. I'm not sure where the belongs_to :report belongs within the chart model, or children of chart model. I get errors when I attempt to access chart.report because the object is of type "Class" undefined local variable or method `report' for #< Class:0x104974b90 The Chart model uses STI so its pulling say.. 'Pie' from the chart_type column in the charts table.. what am I missing?

• I am using jquery ajax using text() but any html written in the XML doesn't render?

  - by Xtian

  So I have Jquery Ajax working real nice, but an issue I am having is in my XML if I want to bold a work or Italicize a sentence, if I do it in the XML using HTML tags it will not show up. I am pretty sure it is due to using the .text(). Any suggestions on a work around for this? $(document).ready(function(){ $.ajax({ type: "GET", url: "xml/sites.xml", dataType: "xml", success: function(xml) { $(xml).find('site').each(function(){ $(this).find('desc').each(function(){ var brief = $(this).find('brief').text(); var long = $(this).find('long').text(); var url = $(this).find('url').text(); $('<div class="brief"></div>').html(brief).appendTo('#link_'+id);

• NUnit with an ASP.net web site

  - by Ed Woodcock

  Hi folks, I'm currently trying to upgrade our build server at work, going from having no build server to having one! I'm using JetBrains TeamCity (having used ReSharper for a couple of years I trust their stuff), and intend to use NUnit and MSBuild. However, I've come up with an issue: it appears that it is not possible to test an ASP.net Web Site with NUnit. I had assumed it would be possible to configure it to test App_Code after build, however it seems that the only way to do tests nicely is through converting the Web Site to a Web Application (which my boss does not like the idea of). Does anyone have a suggestion as to how I could go about this? Please bear in mind that the testing needs to be able to be fired automatically from TeamCity.

• DataMapper save fails but with no errors

  - by Justin Bozonier

  When I try to modify and then save a model using DataMapper I get a SaveFailure exception but no errors. Specifically I see this message: "MonthlyBill#save returned false, MonthlyBill was not saved" This is the code doing the saving: post '/monthly_bills' do with_authenticated_user do |user| description = params[:description] expected_amount = params[:expected_amount] pay_period = params[:pay_period] monthly_bill = MonthlyBill.new(:description=>description, :expected_amount=>expected_amount, :pay_period=>pay_period) user.MonthlyBills << monthly_bill user.save end The User model: class User include DataMapper::Resource property :id, Serial property :email_address, String property :password, String has n, :MonthlyBills has 1, :CurrentPayPeriod end The MonthlyBill model: class MonthlyBill include DataMapper::Resource property :id, Serial property :description, String property :expected_amount,Decimal property :pay_period, Integer belongs_to :user end What is the issue and, more importantly, how can I get DataMapper to tell me more specifically what is wrong?

• Weblogic 10.3 domain unpacking problem

  - by MarkoU

  Hi, I'm trying to unpack a Weblogic 10.3 domain on one of our production servers (SunOS 5.10), but get the following error: $ /opt/bea10/wlserver_10.3/common/bin/unpack.sh -template=/tmp/CM.jar -domain=/opt/bea10/user_projects/CM Error: failed to create the temporary script file Assuming that this is a priviledge problem: where actually the unpack utility tries to create its temporary script files? The unpack script calls a Java class com.bea.plateng.domain.script.Unpacker, so reading the script itself does not reveal the location. I need to ask the sysadmin for the priviledges, so an exact directory location is needed. Of course, the error message is so vague that this might also be some other issue. Any ideas? BR, Marko P.S. Sorry for cross-posting. I tried this question also on Serverfault but got no replies. Perhaps programmers (like myself) do this kind of stuff anyway.

• should i lisense 3rd party controls?

  - by jhon

  some of you will say that this post is not programming related, i think it is! i developed a WebApplication that uses several 3rd party controls using asp.net (c#). i did not buy any license for the 3rd party controls that i am using because i am a freelancer and the controls are too much expensive for me to buy. i already sold the application to several mini-companies that don't care about the license issue. so my question: is it possible that i get sued or caught because of this crime? if yes, then how can they know who am i?

• How do I resize a flat vector icon so that it preserves hard edges in Photoshop (CS4)

  - by Adam Singer

  I recently purchased Drew Wilson's Pictos icon library. It is a library of flat, monochromatic icons for use on the web and elsewhere. The only issue is: they're vectors. I know my way around Illustrator a little bit, but ultimately I want to import these icons into Photoshop and resize to various dimensions. The problem I'm having: when I import an icon and resize it to, say, 20x20 pixels, I notice that there is a fair bit of aliasing around the edges of the icon. I'm sure there is some magic number where the edges of these icons will remain crisp, but I can't find any option or setting that will allow me to size these icons properly. Is there a way in Photoshop to snap these icons to the closest size that removes or minimizes the aliasing?

  hi, im trying to use the mvvmlight DialogMessage. var message = new DialogMessage( "Confirm Delete", RemoveAddressAction) { Button = MessageBoxButton.OKCancel, Caption = "Caption??" }; VS2010 undelines the "Button = MessageBoxButton.OKCancel" line complaining about "Cannot convert source type 'System.Windows.MessageBoxButton [PresentationFramework, Version=3.0.0.0, Culture...] to target type 'System.Windows.MessageBoxItem [GalaSoft.MvvmLight, Version=3.0.0.29216, ...] And a similar issue on the code behind on the view when I try to use the DialogMessage to show the messagebox.

• Java: Executing a Java application in a separate process

  - by _ande_turner_

  Can a Java application be loaded in a separate process using its name, as opposed to its location, in a platform independent manner? I know you can execute a program via ... Process process = Runtime.getRuntime().exec( COMMAND ); ... the main issue of this method is that such calls are then platform specific. Ideally, I'd wrap a method into something as simple as... EXECUTE.application( CLASS_TO_BE_EXECUTED ); ... and pass in the fully qualified name of an application class as CLASS_TO_BE_EXECUTED.

• AutoComplete textbox and "Hide Pointer While Typing" in windows

  - by Joe

  How can the "Hide Pointer While Typing" option be disabled by application? I'm having an issue with the cursor hiding and not getting it back without pressing escape or losing window focus. The application has been written in C# and uses WPF. A technology specific answer is not required because it'll likely be possible using any technology. Here's the scenario: A user can type in a TextBox and an AutoComplete list shows up below the box. Once the user starts typing though, he/she can no longer select an item from the drop down because there is no mouse cursor. I noticed that Firefox does not have this behavior. For example, while typing in a URL in the address bar the mouse cursor never disappears. There are other places I've seen this behavior so I know it must be possible. Any help is greatly appreciated!

• Should I pass the BrainBench Design patterns certification?

  - by Fedyashev Nikita

  I have found Design patterns certification at the Brainbehch. I have heard from people who passed it, that there are many Language-specific patterns questions, mostly from Java and C++. I think that this certification can: force me to improve my skills on Object oriented design and design patterns; improve and structure my knowledge of the domain; give real estimate of my knowledge, which is useful issue itself The only confusion I have about this certification, is that I have to learn C++/Java language specific design patterns, while I mostly do PHP development and don't want to switch to C++/Java. I'm familiar with Java & C++ syntax, read lots of books about different subjects with code snippets in this programming languages. I think, that if I pass well all concepts except language specific patterns at certification, it won't be very good, because this concepts will gain quite low results. What would you recommend in this particular circumstance?

• Why is memory management so visible in Java?

  - by Emil

  I'm playing around with writing some simple Spring-based web apps and deploying them to Tomcat. Almost immediately, I run into the need to customize the Tomcat's JVM settings with -XX:MaxPermSize (and -Xmx and -Xms); without this, the server easily runs out of PermGen space. Why is this such an issue for Java compared to other garbage collected languages? Comparing counts of "tune X memory usage" for X in Java, Ruby, Perl and Python, shows that Java has easily an order of magnitude more hits in Google than the other languages combined.

• Spring FactoryBean and scopes working together

  - by TTar

  I'd like to use FactoryBeans and scopes together. Specifically, I'd like the object created and returned by a FactoryBean to be placed into a specified (perhaps custom) scope. The issue is that doing the following: <bean class="x.y.z.TestFactoryBean" scope="test" /> Results in the FactoryBean itself being scoped, and has somewhat unpredictable behaviour on the object created by the factory. I understand why this is; the factory itself is a first-class spring-managed bean, and has its own lifecycle. However, I can't find a way to specify that the object returned from the factory should itself be scoped. On the other hand, this does exactly what I want (as long as TestFactoryBean does NOT implement the FactoryBean interface): <bean class="x.y.z.TestFactoryBean" name="testFactory"> <bean class="x.y.z.TestBean" factory-bean="testFactory" factory-method="getObject" scope="test" /> So the real question is, how can I make Spring behave like it does for the 2nd example above, but using real FactoryBeans?

• Item-Level Permissions (Edit only their own but, read everyones)...

  - by Jason

  I have a list which I've set item-level permissions on. I set it to allow users to read all items and only edit their own items... The issue is that if I do this then I can still edit all items... If I change it so that I can only read my own and only edit my own then it works as expected... Anyone have any thoughts on why this would be occurring and a solution... I've set the list up to only allow one user account with contribute rights for testing purposes...

• Logging on to two sites simultaneously

  - by James Wakefield

  I want to log on to two sites simultaneously to enable a single sign on solution. We have a smallish wiki that is created with Apple wiki and we have an intranet site on a aspx cms system by Elcom. Both use Active Directory for credentials. Currently they are on different domains, but we could enable a rewrite using our load-balancer (Citrix Netscaler) or IIS. These sites are on different servers, one a mysterious Mac system and the other an IIS v6.0 on windows 2003. Now I am almost certain that a reverse proxy set up will solve this but I really just need someone to agree that this solves this issue, and if there are things I should look out for what they might be. I just want to have an invisible log on screen in an iframe and enter clone the user name and password using javascript.

• Figuring out the resource a lock in SQL Server 2000 affects

  - by Michael Lang

  I am adding a simple web-interface to show data from a commercial off the shelf (COTS) application. This COTS issues locks on any record the user is actively looking at (whether they intend to edit and update it or not). I have found sp_lock and the Microsoft sp_lock2 scripts and can see the locks, so that's all well and good. However, I cannot figure out how I can tell if a specific record I am about to update has been affected by one of these locks. If I submit the update request and there is in fact a lock, the web-interface will wait indefinitely until the user closes the window in the COTS. How can I either: a) determine before issuing an update that the record has been locked OR b) issue an update that will immediately return with a LOCKED status rather than indefinitely waiting on the COTS user to close their window on that record?

• Normal Priority Builds Will Not Build in TFS 2010

  - by 37Stars

  I have two build processes setup in TFS 2010. One build starts when any developer checks code into TFS. The second build runs every night at 12:30am. I can see the builds have a priority of Normal in the queue. However no queued build ever is run until I change the priority to high. They will sit in the queue forever until the priority is changed. It appears there is a normal priority build in the queue that is stuck. However I cannot find it. I can select , , and and not see anything but these builds queued up. I can run them all and the next day I have queued builds again. I say this because I see the Build Service is configured for port 9192, which leads me to believe there is or was another Build Service on port 9191. Any idea how to resolve this issue? Thanks

• How can we store password other than plain text?

  - by Eric

  I've found numerous posts on stackoverflow on how to store user passwords. However, I need to know what is the best way to store a password that my application needs to communicate with another application via the web? Currently, our web app needs to transmit data to a remote website. To upload the data, our web app reads the password from a text file and creates the header with payloads and submits via https. This password in plain text on the file system is the issue. Is there any way to store the password more securely? Thanks!

• best way to filter out non-representational elements

  - by nonano

  Hi there, I am using phpQuery in order to apply some twaks to editorial content. As its syntax is the same as jQuery, I consider this a dom scripting issue. To get rid of elements which are not representing anything, but wrapping other stuff (like the div in <div><p>blah</p></div> I came up with this selector: ['div:not([align][class][id][style][title][dir][lang][onclick][ondblclick][onmousedown] [onmouseup][onmouseover][onmousemove][onmouseout][onkeypress][onkeydown][onkeyup])'] which looks quite monstrous for a selector simply aming on Divs which just do not have any (valid) attribute. I guess there must be a more straight-forward way to accomplish that, right? Edit: Oh, and I just noticed that it even doesn't do wat I intended to ...

• Programming CLI Commands in Program [C / LINUX]

  - by Blackbinary

  I am attempting to make a program in C which presents a GUI and allows the user to select from a list of applications, which to install on the computer. I can manage the gui, but I've never been taught how to actually issue command line commands. I know with bash its just apt-get install firefox for example, but how do I do such a thing with C? i.e. on click, the program runs 'apt-get install The other problem is I'm not familiar with the proper name for this interaction, so it is hard to search. Thanks for the help
