• What is your company's stance on Developers using Laptops?

  - by codepunk

  I am a developer and my company is moving towards a "no laptop" policy in fear of them being lost or stolen and source code being compromised. Now I don't work for NASA, the military or anything labeled Top Secret but our code is very important to our business nonetheless (as all source code would be). I'll be honest, I disagree with this policy against laptops and wanted to see what others think. I'd like to know: What is your team/company's stance on laptops Your company's size and/or field (small, medium or large, Fortune 500, etc). Whether you've had to take any extra precautions (signing any additional legal, ensure your hard drive is encrypted, etc). Thanks!

• Xcode + Perforce: it frequently shows me the spinning wheel for no reason! What can i do?

  - by GamingHorror

  While working on an Xcode project i keep getting the spinning wheel while switching files, scrolling, searching, typing, debugging, removing breakpoints, switching back from another app or saving. It also happens before compiling but usually it just happens from time to time for no apparent reason. This is the second time this started happening in a Xcode project and it's driving me nuts. It completely breaks my flow of work to have to wait for the spinning wheel to go away (2-5 seconds). What on earth could i possibly do to ... figure out what's causing the problem? resolve the problem? More details: When any project is small, everything is super-smooth with Xcode and Perforce. Two of my projects eventually had this spinning wheel problem after about 4 weeks of work. It only happened with those two projects so far. They consist of around 1000-1200 files in source control, most of them assets. The problem occurs even if i manually check out the whole project in Perforce. The problem is gone when i copy the project directory and work in the copy which is no longer under source control, or if i create a branch in Perforce and work in the branch (under source control). One of these projects i shared with a colleague, and he had exactly the same issues on his Mac. We eventually switched to Subversion and the spinning-wheel issue immediately went away. Now that i've received an updated copy of the project and simply put it under Perforce as a new project, the problem also went away (so far it did not resurface). It leads me to think that it may be caused by a larger number of file revisions. The server itself (version 2009.1) is on a different (Windows) machine on my LAN, so there's definetely no Internet lag involved. The complete repository is just 1 GB in size spread over a dozen projects or so. I'm sorry if the question seems more like a support inquiry for Perforce. However i'm using the free version of Perforce so i'm not entitled to get support from them. I hope no one minds me asking here. I'm really bummed out by this. I don't want to have to create a new branch for the project each time the spinning wheel problem surfaces.

• Can I configure AutoMapper to read from custom column names when mapping from IDataReader?

  - by rohancragg

  Psuedo code for mapping configuration (as below) is not possible since the lambda only lets us access Type IDataReader, wheras when actually mapping, AutoMapper will reach into each "cell" of each IDataRecord while IDataReader.Read() == true: var mappingConfig = Mapper.CreateMap<IDataReader, IEnumerable<MyDTO>>(); mappingConfig.ForMember( destination => destination.???, options => options.MapFrom(source => source.???)); Can anyone think of a way to do this using AutoMapper configuration at runtime or just some other dynamic approach that meets the requirement below. The requirement is to support any incoming IDataReader which may have column names that don't match the property names of MyDTO and there is no naming convention I can rely on. Instead we'll ask the user at runtime to cross-reference the expected column names with the actual column names found in the IDataReader via IDataReader.GetSchemaTable().

• Visual Studio 2008 hangs while opening aspx/ascx file.

  - by rafek

  Hi all! I've issue with VS08. I've got Web Application project (vb.net). Whenever I try to open an aspx or ascx (in Source view - just double clicking on Solution Explorer) the file opens, but VS hangs and is not responding. The only way to restart VS is then by killing it's process. And it happens all the time with these types of files. :/ Reinstall didn't work. In addition, the only plugin I've installed with this instance of VS is ClearCase source control plugin.

• How can I use BeanUtils copyProperties to copy from boolean to Boolean?

  - by carrier

  BeanUtils copyProperties, out of the box, doesn't seem to handle copying from Boolean object properties to boolean primitive properties. I figured I could create and register a converter to handle this, but that just didn't seem to work. So, how can I use BeanUtils to copy the properties from class Source to class Destination where: public class Destination { private boolean property; public boolean isProperty() { return property; } public void setProperty(boolean property) { this.property = property; } } public class Source{ private Boolean property; public Boolean getProperty() { return property; } public void setProperty(Boolean property) { this.property = property; } }

• Optimally reducing maximum flow

  - by ArIck

  Given a parameter k, I'm trying to delete k edges from a directed graph such that the maximum flow is reduced by as much as possible. The graph has a source s and a sink t, and the capacity of each edge is one. The graph may or may not contain cycles. My proposed solution would be to first perform a topological sorting on the graph, using an algorithm that "forgives" cycles -- perhaps by ignoring edges that lead us back to the source. Then (assuming k = 1): i = 0 for each vertex u order by topological(u) for each edge (u, v) order by topological(v) descending if topological(v) > topological(u) then delete (u, v) if ++i = k then return else // edge doesn't contribute to max flow, ignore Would this work, or am I totally off-track here?

• Is it possible to do have Capistrano do a checkout over a reverse SSH tunnel?

  - by James A. Rosen

  I am developing an application that resides on a public host but whose source I must keep in a Git repository behind a corporate firewall. I'm getting very tired of the slowness of deploying via scp (copying the whole repository and shipping it over SSH on each deploy) and would like to have the remote host simply do a git pull to update. The problem is that the firewall prohibits incoming SSH connections. Would it be possible for me to set up an SSH tunnel from my computer to the deployment computer and use my repository as the source for the git pull? After all, git is distributed, so my copy is just as valid a repository as the central one. If this is possible, what would the tunnel command and the Capistrano configuration be? I think the tunnel will look something like ssh -R something:deployserver.com:something [email protected]

• Is there a Perl Syntax Highlighter (outputting to HTML) like PHP's GeSHi?

  - by nebukadnezzar

  Most PHP Developers are likely familar with the Syntax Highlighter called "GeSHi", which takes code, highlights it, with the use of HTML and CSS: include('geshi.php'); $source = 'echo "hello, world!"; $language = 'php'; $path = 'geshi/'; $geshi = new GeSHi($source, $language, $path); echo $geshi->parse_code(); GeSHi Supports a wide range of languages. I wonder, is there a similar Module for Perl?

• Is there simple way to play an rtp video/audio stream in WPF?

  - by Robin

  I need to create a WPF control that will play an rtp stream with the requirement that the latency needs to be as low as possible. I've looked at the following two projects: http://vlcdotnet.codeplex.com/ http://wpfmediakit.codeplex.com/ As far as I know, I can't use VLC because we're shipping a commercial application with a more restrictive license than GPL (i.e. we can't ship our source). Wpf media kit is nice, but I can't seem to find a good/free rtp directshow source filter and I wanted to ask if there is a simpler solution out there that I'm missing before I jump into writing my own. Any ideas?

• Autoformat pom.xml without using m2eclipse plugin

  - by hashable

  I don't use the Eclipse maven plugin while developing in Eclipse. I generate my Eclipse classpath externally using the following command: mvn eclipse:eclipse This has worked fine for quite some time and I am not inclined to add a maven plugin. However, I would like to be able to "autoformat" my pom.xml file. My pom.xml is not showing up as a "Source" file and therefore the contextual "Source" menu doesn't show up. Control-Shift-F doesn't work either. Is there a way to do this without installing the m2eclipse plugin? Is there any other generic "XML Editor" plugin that can help with this?

• How can I create a generic constructor? (ie. BaseClass.FromXml(<param>)

  - by SofaKng

  I'm not sure how to describe this but I'm trying to create a base class that contains a shared (factory) function called FromXml. I want this function to instantiate an object of the proper type and then fill it via an XmlDocument. For example, let's say I have something like this: Public Class XmlObject Public Shared Function FromXml(ByVal source as XmlDocument) As XmlObject // <need code to create SPECIFIC TYPE of object and return it End Function End Class Public Class CustomObject Inherits XmlObject End Class I'd like to be able to do something like this: Dim myObject As CustomObject = CustomObject.FromXml(source) Is this possible?

• javax.servlet import cannot be resolved after moving web servlet

  - by Michael Kjörling

  I have written a small web servlet to run under Tomcat, using Eclipse Helios. In its old, non-source-controlled location, everything was fine, but now I need to add this to our source control system. Moving the old files out of the way, creating a new workspace, setting up the server connection and copying and importing the existing projects into the new workspace all worked fine once I figured out how to do it, but I can't get the servlet to build. Instead, I get a whole bunch of cannot be resolved to a type errors talking about various servlet class types; HttpServlet, HttpServletRequest, ServletException, etc. Another error that is almost certainly related is The import javax.servlet cannot be resolved. I am obviously missing something very basic, but I'm new to this (and not having the terminology really down pat probably doesn't help me Google for an answer). Any suggestions as to what I might be missing would be greatly appreciated.

• Python Importing object that originates in one module from a different module into a third module

  - by adewinter

  I was reading the sourcode for a python project and came across the following line: from couchexport.export import Format (source: https://github.com/wbnigeria/couchexport/blob/master/couchexport/views.py#L1 ) I went over to couchexport/export.py to see what Format was (Class? Dict? something else?). Unfortunately Format isn't in that file. export.py does however import a Format from couchexport.models where there is a Format class (source: https://github.com/wbnigeria/couchexport/blob/master/couchexport/models.py#L11). When I open up the original file in my IDE and have it look up the declaration, in line I mentioned at the start of this question, it leads directly to models.py. What's going on? How can an import from one file (export.py) actually be an import from another file (models.py) without being explicitly stated?

• Easier way to move a project in Eclipse

  - by myplacedk

  My projects changes location, and I need to tell Eclipse this. Today I just delete the project and import it from the new location. But I have a lot of projects, they change location often and the paths a very complicated. I'd like a better way to manage this in Eclipse. For example: J:\iteration234_abc\foo\bar\baz\iffle\dizzle\Project Only the root-folder changes (iteration-number and the idenfier "abc"). After that there are lot of folders. Many folders has tons of subfolders with similar names, which makes finding the folder with GUI time-consuming and very boring. It would be so nice if I could just edit the path. As you may have guessed: The J-drive is a network drive, provided by the source control system. The way to tell source control that I'm working on another itertion, is to continue my work in a different folder. My actual Eclipse workspace normally doesn't contain any projects.

• WPF data templates

  - by imekon

  I'm getting started with WPF and trying to get my head around connecting data to the UI. I've managed to connect to a class without any issues, but what I really want to do is connect to a property of the main window. Here's the XAML: <Window x:Class="test3.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:custom="clr-namespace:test3" Title="MainWindow" Height="350" Width="525"> <Window.Resources> <CollectionViewSource Source="{Binding Source={x:Static Application.Current}, Path=Platforms}" x:Key="platforms"/> <DataTemplate DataType="{x:Type custom:Platform}"> <StackPanel> <CheckBox IsChecked="{Binding Path=Selected}"/> <TextBlock Text="{Binding Path=Name}"/> </StackPanel> </DataTemplate> </Window.Resources> <Grid> <ListBox ItemsSource="{Binding Source={StaticResource platforms}}"/> </Grid> Here's the code for the main window: public partial class MainWindow : Window { ObservableCollection<Platform> m_platforms; public MainWindow() { m_platforms = new ObservableCollection<Platform>(); m_platforms.Add(new Platform("PC")); InitializeComponent(); } public ObservableCollection<Platform> Platforms { get { return m_platforms; } set { m_platforms = value; } } } Here's the Platform class: public class Platform { private string m_name; private bool m_selected; public Platform(string name) { m_name = name; m_selected = false; } public string Name { get { return m_name; } set { m_name = value; } } public bool Selected { get { return m_selected; } set { m_selected = value; } } } This all compiles and runs fine but the list box displays with nothing in it. If I put a breakpoint on the get method of Platforms, it doesn't get called. I don't understand as Platforms is what the XAML should be connecting to!

• Unusual Subversion Folders Appeared After Update

  - by Mark Lansdown

  Hello Everyone, I have been using Subversion for about 2 years to manage a large C# project. On a recent Subversion update, a number of new folders were added to my source code folder: \conf \db \locks \hooks 35+ files were also added during the update, all appearing under the 4 new folders. I haven't changed any client (I use TortoiseSVN) or server software related to Subversion, so I'm puzzled why these folders and files were suddenly introduced. It also seems strange that files seemingly related to the internal workings of Subversion are now part of my source code repository. Can anyone shed some light on why this happened? Thanks in advance, Mark

• Symfony2 Syntax Errors (in vendor files)

  - by user1665246

  To maintain code integrity across our servers we'd like to keep the /vendor/* directory under source control, rather than use composer to download files each time we roll out onto another server - i.e. we can be certain that the /vendor/* files are identical. We run a syntax checker against all files committed to source control and run across the following error: File '/vendor/sensio/generator-bundle/Sensio/Bundle/GeneratorBundle/Resources/skeleton/bundle/Bundle.php' failed the PHP syntax check with the following error: PHP Parse error: syntax error, unexpected '}', expecting T_NS_SEPARATOR in /vendor/sensio/generator-bundle/Sensio/Bundle/GeneratorBundle/Resources/skeleton/bundle/Bundle.php on line 3 Is the "error" in this file intentional ? Any help appreciated. File contents below: <?php namespace {{ namespace }}; use Symfony\Component\HttpKernel\Bundle\Bundle; class {{ bundle }} extends Bundle { }

• Best Practice to write Connection string for heavy traffic ASP.NET Web Application

  - by hungrycoder

  What is the best way to define connection string for a web application that has minimum 500 live users on the internet in terms of connection pooling. And load factors to consider? Suppose I have connection string as follows: initial catalog=Northwind; Min Pool Size=20;Max Pool Size=500; data source=localhost; Connection Timeout=30; Integrated security=sspi" as Max Pool Size is 500 and as live users exceed 500 say 520 will the remaining 20 users experience slower page load?? Or what if I have connection string as follows which doesn't talks anything about pooling or Connection time out? How the application behaves then? initial catalog=Northwind; data source=localhost; Integrated security=sspi" I'm using "Using statements" however to access the MYSQL database.

• ns-2 c++ file changes

When I get to the stage where I'm messing around with C++ source files and related program C++ source files as stated in http://www.isi.edu/nsnam/ns/tutorial/index.html, I don't know what to do as there are enough inconsistencies between the version of ns-2 that I downloaded (which is the latest stable build) and the guide. What would your recommendations in this case, as I don't know what to do with it as a newbie? Thanks in advance for your help!

• How to configure a OCUnit test bundle for a framework?

  - by GuidoMB

  I've been developing a Mac OS X framework and I want to use OCUnit in my XCode 3.2.1 project. I've followed several tutorials on how to configure a OCUnit test bundle. The problem is that when I create a test case that uses a function that is defined in one of the framework's sources, I get a building error telling me that the symbol is not found. I made the test bundle dependent of my project's target as the tutorial said, but that doesn't seem to be problem. First I thought that I could solve this problem by dragging the framework's source files into the compile sources section within the Test bundle target, but then all the symbols referenced from that source file started to show up in the build errors, so that seems to not be a good solution/idea. How can I configure my unit test bundle so it builds properly?

• Are there Adaptive Replacement Cache patent-free alternatives?

  - by aleccolocco

  An open source high-performance project I'm working on needs to keep a cache of parsed/compiled files. A plain LRU or a plain LFU wouldn't fit. Plain LRU wouldn't work as there will be remote batch/spider processes hitting the service regularly. Plain LFU wouldn't work because content will age. ARC seems like the perfect solution but since IBM holds patents to it at least one open source project dropped it. Are there any (good enough) alternatives? EDIT: I'm not looking for exactly the same thing, just something that could handle those two situations. Perhaps some simple strategy with timestamps and sources. There have to be many programmers who faced this situation before. That's why the "good enough" bit.
