  • package issue with ubuntu 10.10 and passenger requirements

    - by user368937
    I'm trying to get Passenger working with Ubuntu 10.10 and I'm running into a problem. It seems that the passenger installer is not recognizing the virtual package. I'm getting this error: Code: passenger-install-apache2-module ... * OpenSSL support for Ruby... not found ... And then it says, run this: * To install OpenSSL support for Ruby: Please run apt-get install libopenssl-ruby as root. When I run the above command, it refers to the libruby package: sudo apt-get install libopenssl-ruby Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'libruby' instead of 'libopenssl-ruby' libruby is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 43 not upgraded. When I look at the details for libruby, it says it provides libopenssl-ruby: Code: Provides: libbigdecimal-ruby, libcurses-ruby, libdbm-ruby, libdl-ruby, libdrb-ruby, liberb-ruby, libgdbm-ruby, libiconv-ruby, libopenssl-ruby, libpty-ruby, libracc-runtime-ruby, libreadline-ruby, librexml-ruby, libsdbm-ruby, libstrscan-ruby, libsyslog-ruby, libtest-unit-ruby, libwebrick-ruby, libxmlrpc-ruby, libyaml-ruby, libzlib-ruby And when I rerun the passenger installer, it gives the same error: Code: passenger-install-apache2-module ... * OpenSSL support for Ruby... not found ... Let me know if you need more info. How do I fix this?

  • Visual Studio template not showing

    - by David
    Hi all I've followed this tutorial to try to add a template to Visual Studio: http://www.switchonthecode.com/tutorials/visual-studio-how-to-create-item-templates The template I have created is designed to add one predefined .aspx and one predefined .aspx.cs file to the project. The folder contains the following files: MoosePage.aspx MoosePage.aspx.cs MoosePage.vstemplate MoosePageItemTemplateIcon.ico The .vstemplate file looks like this: <VSTemplate Type="Item" Version="2.0.0" xmlns="http://schemas.microsoft.com/developer/vstemplate/2005"> <TemplateData> <Name>MoosePage</Name> <Description>MoosePage Template</Description> <DefaultName>NewMoosePage</DefaultName> <ProjectType>CSharp</ProjectType> <Icon>MoosePageItemTemplateIcon.ico</Icon> </TemplateData> <TemplateContent> <ProjectItem TargetFileName="$fileinputname$.aspx" ReplaceParameters="true"> MoosePage.aspx </ProjectItem> <ProjectItem TargetFileName="$fileinputname$.aspx.cs" ReplaceParameters="true"> MoosePage.aspx.cs </ProjectItem> </TemplateContent> </VSTemplate> I have zipped the files up (.zip not .zipx) and placed the zip folder in My Documents\Visual Studio 2008\Templates\ItemTemplates\VisualWebDeveloper. I have restarted Visual Studio. When I go into my website project and choose Add New Item, I don't see my new template. Can anyone suggest what might have gone wrong? Thanks David

  • Simulate Windows Service with ASP.NET

    - by Bayonian
    Hi, I have small web app that generate PDF files as a report. I'm trying to delete those generated PDF files after 10 sec that they are generated. What I want to do is to read a folder with PDF files every 10 sec, and delete all the PDF files inside that folder. I read this post of Easy Background Tasks in ASP.NET. The following code is the VB version. Protected Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs) AddTask("DoStuff", 10) End Sub Private Sub AddTask(ByVal name As String, ByVal seconds As Integer) OnCacheRemove = New CacheItemRemovedCallback(CacheItemRemoved) HttpRuntime.Cache.Insert(name, seconds, Nothing, DateTime.Now.AddSeconds(seconds), Cache.NoSlidingExpiration, CacheItemPriority.NotRemovable, _ OnCacheRemove) End Sub Public Sub CacheItemRemoved(ByVal k As String, ByVal v As Object, ByVal r As CacheItemRemovedReason) ' do stuff here if it matches our taskname, like WebRequest DeletePDFilesInFoler() ' re-add our task so it recurs AddTask(k, Convert.ToInt32(v)) End Sub But I got this error Delegate 'System.Web.Caching.CacheItemRemovedCallback' requires an 'AddressOf' expression or lambda expression as the only argument to its constructor. If this code works, where I should put it. Right, now I'm putting it in the master page. How to get this error out? Thank you

  • Undefined symbols compiling apache module mod_transform on Mac OS X

  • Where can I find free and open data?

    - by kitsune
    Sooner or later, coders will feel the need to have access to "open data" in one of their projects, from knowing a city's zip to a more obscure information such as the axial tilt of Pluto. I know data.un.org which offers access to the UN's extensive array of databases that deal with human development and other socio-economic issues. The other usual suspects are NASA and the USGS for planetary data. There's an article at readwriteweb with more links. infochimps.org seems to stand out. Personally, I need to find historic commodity prices, stock values and other financial data. All these data sets seem to cost money however. Clarification To clarify, I'm interested in all kinds of open data, because sooner or later, I know I will be in a situation where I could need it. I will try to edit this answer and include the suggestions in a structured manners. A link for financial data was hidden in that readwriteweb article, doh! It's called opentick.com. Looks good so far! Update I stumbled over semantic data in another question of mine on here. There is opencyc ('the world's largest and most complete general knowledge base and commonsense reasoning engine'). A project called UMBEL provides a light-weight, distilled version of opencyc. Umbel has semantic data in rdf/owl/skos n3 syntax. The Worldbank also released a very nice API. It offers data from the last 50 years for about 200 countries

  • Semantic Grid System, Media Query issue

    - by Andy
    I'm using the Semantic Grid System to build a responsive site. However, something isn't quite right with the media queries that should obviously kick in once it hits a particular screen size. I'll reference what i mean with their example on the website : if I view this on my iPhone for example, given that it is supposed to adjust to a single column structure on a mobile device, it still throws out the web version of the page. That is true for both Safari and Chrome on my iPhone. However, if I use the RWD bookmarklet to check it's appearance at different resolutions it appears as expected for the mobile resolution. Also, ironically, if I resize the page in Safari on my desktop it also adjusts accordingly once I get down to the approriate screen size, but not in Firefox. The media query that it uses once it hits 720px is @media screen and (max-width: 720px) { #maincolumn, #sidebar { .column(12); margin-bottom: 1em; } } and I might be wide of the mark here but I think that must be the issue. But given that this is directly from the semantic.gs website I'm not inclined to question their own code. Any idea what the problem might be?

  • Is CSS Inheritance in Internet Explorer 8 still buggy?

    - by rrrr
    I have a situation that I am looking at where certain CSS properties will not be inherited. This revolves around tables and IE8. Using the sample HTML below I cannot get the text within the table to inherit the green colour. This works in Firefox and Chrome, but not IE8 and from reading up this seems to have always been a problem in IE but was meant to be working in version 8 from what I read. I have tried to specify the inherit value everywhere possible, but to no avail so the question is whether the CSS inheritance support in IE8 is buggy, or am I missing something? I don't want answer changing inline CSS to be classes and I certainly dont wan't any comments on tables as this all stems from building and designing HTML emails where inline CSS and tables are essential. <html> <head></head> <body> <table style="color: green;"> <tr> <td> <span>Span</span> <p>Paragraph</p> <div>Div</div> <table style="color:inherit;"> <tr> <td>Table</td> </tr> </table> </td> </tr> </table> </body> </html>

  • Extracting bool from istream in a templated function

    - by Thomas Matthews
    I'm converting my fields class read functions into one template function. I have field classes for int, unsigned int, long, and unsigned long. These all use the same method for extracting a value from an istringstream (only the types change): template <typename Value_Type> Value_Type Extract_Value(const std::string& input_string) { std::istringstream m_string_stream; m_string_stream.str(input_string); m_string_stream.clear(); m_string_stream >> value; return; } The tricky part is with the bool (Boolean) type. There are many textual representations for Boolean: 0, 1, T, F, TRUE, FALSE, and all the case insensitive combinations Here's the questions: What does the C++ standard say are valid data to extract a bool, using the stream extraction operator? Since Boolean can be represented by text, does this involve locales? Is this platform dependent? I would like to simplify my code by not writing my own handler for bool input. I am using MS Visual Studio 2008 (version 9), C++, and Windows XP and Vista.

  • Using Prism with Ninject

    - by stiank81
    Is anyone out there using the Prism framework with Ninject instead of Unity? I need some functionality Unity isn't supporting yet, and I've decided to switch the IoC container to Ninject. I'm struggling a bit with the replace though.. What I need to use from Prism is the EventAggregator and the RegionManager. I have seen this sample that actually does the replace, but this is written for an older version of Prism, and several of the classes seems to have changed etc. So I ended up all confused after looking doing some effort in trying to rewrite it. So - my question is basically: How can I replace Unity with Ninject? What are the necessary steps? Initially I assumed I could write a simple bootstrapper that creates and configures a Ninject container and uses this to resolve all other objects. I bind IEventAggregator to EventAggregator and IRegionManager to RegionManager, but it fails when creating the Shell and the RegionManager.CreateRegion is called. Problem is that it seems like I need to set a ServiceLocator somewhere as it fails on this line: IServiceLocator locator = ServiceLocator.Current; Any ideas and tips along the way?

  • Workaround for GNU Make 3.80 eval bug

    - by bengineerd
    I'm trying to create a generic build template for my Makefiles, kind of like they discuss in the eval documentation. I've run into a known bug with GNU Make 3.80. When $(eval) evaluates a line that is over 193 characters, Make crashes with a "Virtual Memory Exhausted" error. The code I have that causes the issue looks like this. SRC_DIR = ./src/ PROG_NAME = test define PROGRAM_template $(1)_SRC_DIR = $$(SRC_DIR)$(1)/ $(1)_SRC_FILES = $$(wildcard $$($(1)_SRC_DIR)*.c) $(1)_OBJ_FILES = $$($(1)_SRC_FILES):.c=.o) $$($(1)_OBJ_FILES) : $$($(1)_SRC_FILES) # This is the problem line endef $(eval $(call PROGRAM_template,$(PROG_NAME))) When I run this Makefile, I get gmake: *** virtual memory exhausted. Stop. The expected output is that all .c files in ./src/test/ get compiled into .o files (via an implicit rule). The problem is that $$($(1)_SRC_FILES) and $$($(1)_OBJ_FILES) are together over 193 characters long (if there are enough source files). I have tried running the make file on a directory where there is only 2 .c files, and it works fine. It's only when there are many .c files in the SRC directory that I get the error. I know that GNU Make 3.81 fixes this bug. Unfortunately I do not have the authority or ability to install the newer version on the system I'm working on. I'm stuck with 3.80. So, is there some workaround? Maybe split $$($(1)_SRC_FILES) up and declare each dependency individually within the eval?

  • OpenCV: Shift/Align face image relative to reference Image (Image Registration)

    - by Abhischek
    I am new to OpenCV2 and working on a project in emotion recognition and would like to align a facial image in relation to a reference facial image. I would like to get the image translation working before moving to rotation. Current idea is to run a search within a limited range on both x and y coordinates and use the sum of squared differences as error metric to select the optimal x/y parameters to align the image. I'm using the OpenCV face_cascade function to detect the face images, all images are resized to a fixed (128x128). Question: Which parameters of the Mat image do I need to modify to shift the image in a positive/negative direction on both x and y axis? I believe setImageROI is no longer supported by Mat datatypes? I have the ROIs for both faces available however I am unsure how to use them. void alignImage(vector<Rect> faceROIstore, vector<Mat> faceIMGstore) { Mat refimg = faceIMGstore[1]; //reference image Mat dispimg = faceIMGstore[52]; // "displaced" version of reference image //Rect refROI = faceROIstore[1]; //Bounding box for face in reference image //Rect dispROI = faceROIstore[52]; //Bounding box for face in displaced image Mat aligned; matchTemplate(dispimg, refimg, aligned, CV_TM_SQDIFF_NORMED); imshow("Aligned image", aligned); } The idea for this approach is based on Image Alignment Tutorial by Richard Szeliski Working on Windows with OpenCV 2.4. Any suggestions are much appreciated.

  • Oracle rownum in db2 - Java data archiving

    - by HonorGod
    I have a data archiving process in java that moves data between db2 and sybase. FYI - This is not done through any import/export process because there are several conditions on each table that are available on run-time and so this process is developed in java. Right now I have single DatabaseReader and DatabaseWriter defined for each source and destination combination so that data is moved in multiple threads. I guess I wanted to expand this further where I can have Multiple DatabaseReaders and Multiple DatabaseWriters defined for each source and destination combination. So, for example if the source data is about 100 rows and I defined 10 readers and 10 writer, each reader will read 10 rows and give them to the writer. I hope process will give me extreme performance depending on the resources available on the server [CPU, Memory etc]. But I guess the problem is these source tables do not have primary keys and it is extremely difficult to grab rows in multiple sets. Oracle provides rownum concept and i guess the life is much simpler there....but how about db2? How can I achieve this behavior with db2? Is there a way to say fetch first 10 records and then fetch next 10 records and so on? Any suggestions / ideas ? Db2 Version - DB2 v8.1.0.144 Fix Pack Num - 16 Linux

  • Perl Lingua giving weird error on install

    I am trying to install perl Lingua onto a unix system (ubuntu, latest version).

  • Can a call to WaitHandle.SignalAndWait be ignored for performance profiling purposes?

    - by Dan Tao
    I just downloaded the trial version of ANTS Performance Profiler from Red Gate and am investigating some of my team's code. Immediately I notice that there's a particular section of code that ANTS is reporting as eating up to 99% CPU time. I am completely unfamiliar with ANTS or performance profiling in general (that is, aside from self-profiling using what I'm sure are extremely crude and frowned-upon methods such as double timeToComplete = (endTime - startTime).TotalSeconds), so I'm still fiddling around with the application and figuring out how it's used. But I did call the developer responsible for the code in question and his immediate reaction was "Yeah, that doesn't surprise me that it says that; but that code calls SignalAndWait [which I could see for myself, thanks to ANTS], which doesn't use any CPU, it just sits there waiting for something to do." He advised me to simply ignore that code and look for anything ELSE I could find. My question: is it true that SignalAndWait requires NO CPU overhead (and if so, how is this possible?), and is it reasonable that a performance profiler would view it as taking up 99% CPU time? I find this particularly curious because, if it's at 99%, that would suggest that our application is often idle, wouldn't it? And yet its performance has become rather sluggish lately. Like I said, I really am just a beginner when it comes to this tool, and I don't know anything about the WaitHandle class. So ANY information to help me to understand what's going on here would be appreciated.

  • Using Apache Camel how do I unmarshal my deserialized object that comes in through a CXF Endpoint?

Data Model: public class AddressBook : INotifyPropertyChanged { private int _houseNumber; public int HouseNumber { get { return _houseNumber; } set { _houseNumber = value; NotifyPropertyChanged("HouseNumber"); } } public event PropertyChangedEventHandler PropertyChanged; protected void NotifyPropertyChanged(string sProp) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(sProp)); } } } Binding in Code: AddressBook book = new AddressBook(); book.HouseNumber = 123; TextBlock tb = new TextBlock(); Binding bind = new Binding("HouseNumber"); bind.Source = book; bind.Mode = BindingMode.OneWay; tb.SetBinding(TextBlock.TextProperty, bind); // Text block displays "123" myGrid.Children.Add(tb); book.HouseNumber = 456; // Text block displays "123" but PropertyChanged event fires When the data is first bound, the text block is updated with the correct house number. Then, if I change the house number in code later, the book's PropertyChanged event fires, but the text block is not updated. Can anyone tell me why? Thanks, Ben

  • What's the strangest corner case you've seen in C# or .NET?

    - by Jon Skeet
    I collect a few corner cases and brain teasers and would always like to hear more. The page only really covers C# language bits and bobs, but I also find core .NET things interesting too. For example, here's one which isn't on the page, but which I find incredible: string x = new string(new char[0]); string y = new string(new char[0]); Console.WriteLine(object.ReferenceEquals(x, y)); I'd expect that to print False - after all, "new" (with a reference type) always creates a new object, doesn't it? The specs for both C# and the CLI indicate that it should. Well, not in this particular case. It prints True, and has done on every version of the framework I've tested it with. (I haven't tried it on Mono, admittedly...) Just to be clear, this is only an example of the kind of thing I'm looking for - I wasn't particularly looking for discussion/explanation of this oddity. (It's not the same as normal string interning; in particular, string interning doesn't normally happen when a constructor is called.) I was really asking for similar odd behaviour. Any other gems lurking out there?

  • Error Building Gem

    - by Joel M.
    I tried to install the following gem: http://github.com/maxjustus/sinatra-authentication on Windows 7 running Ruby 1.9 from the One-Click Installer. I got the following error: Microsoft Windows [Version 6.1.7600] Copyright (c) 2009 Microsoft Corporation. All rights reserved. C:\Users\Joel>gem install sinatra-authentication Building native extensions. This could take a while... ERROR: Error installing sinatra-authentication: ERROR: Failed to build gem native extension.

Gem files will remain installed in C:/Ruby19/lib/ruby/gems/1.9.1/gems/yajl-ruby- 0.7.5 for inspection. Results logged to C:/Ruby19/lib/ruby/gems/1.9.1/gems/yajl-ruby-0.7.5/ext/gem_mak e.out I looked everywehere online, tried to install earlier versions, and attempted a manual install without success (it gave me a stack too deep error). I suspect there are problems with the yajl-ruby gem (http://github.com/brianmario/yajl-ruby), a dependency? (I think) The logs in gem_make.out show: C:/Ruby19/bin/ruby.exe extconf.rb creating Makefile make 'make' is not recognized as an internal or external command, operable program or batch file. Do you have any idea as to how to solve this? Thanks!

  • Eclipse randomly exits after installation of Blackberry plugin/SDK

    - by canadiancreed
    Hello all Since adding the Blackberry Java classes from their website into eclipse, I've had it where eclipse will randomly close, with no discernible pattern, rhyme, error or reason. Here is the environment/software packages that I am using: Windows XP SP2 Eclipse v3.5.1 Blackberry Java Plugin v1.1.1.200911111641-15 Blackberry Java SDK 4.5.0.21 I've tried the usual steps of complete uninstall and reinstallation of Eclipse and the accompanying plugins on multiple systems with the same configuration, including one that had a fresh install of Windows XP SP2. Upgrading to Eclipse 3.6 didn't work (the plugin wont' install as it's the wrong version), nor the downgrade to 3.4 for the same reason. I also increased the heap size to 512 (system has two gigs of memory) as some research into Eclipse doing this type of thing with Groovy was resolved that way, but again, no dice. Eclipse works great when the blackberry plugins are not installed, and no entries of errors or issues in the event log are helping to show what the issue with these plug-ins might be. So if anyone has ran into this issue, and even better, has a solution, I'd love to hear about it. Thanks in advance. EDIT: An additional to my issue, autoComplete with the Blackberry SDK seems to make this extremely unstable, like almost a guaranteed crash. Is this fixable at all?

  • Blackberry how to display message in app if device got no internet connection?

    - by Johannes
    Hello I've just started with programming for the Blackberry device. I'm using version 5 of the API. I'm building a very simple application which is just a browserfield. So far it's all working great. I can display my browserfield with the content I need. The problem I'm having now is if the device doesn't have an active internet connection I get the ugly "Error requesting content for" message. I would need to someone display my own message if the device doesn't have an active connection. Something like "You need to have an active internet connection to use this application" with an Exit button which closes the app. I've tried to find this for hours but no luck. Hopefully it's something relatively easy so I can get help here. Here's my code so far: package com.mycompany.webview; import net.rim.device.api.browser.field2.*; import net.rim.device.api.ui.*; import net.rim.device.api.ui.container.*; public class webview extends UiApplication { public static void main(String[] args) { webview app = new webview(); app.enterEventDispatcher(); } public webview() { pushScreen(new webviewScreen()); } } class webviewScreen extends MainScreen { public webviewScreen() { BrowserField myBrowserField = new BrowserField(); add(myBrowserField); myBrowserField.requestContent("http://www.google.com"); } } Would really appreciate some help please. Thanks

  • What off-the-shelf licensing system will meet my needs?

    - by Anders Pedersen
    I'm looking for an off-the-shelf license system for desktop software. After some research on the net -- and of course here on StackOverflow -- I haven't found one the suits our needs. I have a couple of must-have features and some would-be-nice features: Must have: Encrypted unlock key Possibility to automate the unlock key generation on my website User info in key so that I can show name and company in an about box and perhaps in reports Nice to have: License managing tools Online activation Nice upgrade possibilities to a version with concurrent license model and subscription model I have looked at Manco, but I find them difficult to work with and the documentation is minimal. Further, I couldn't get the name in the key. Also, the automatic generation of a key on my website has to be done with an application web service, but I would rather program against a DLL. Next I looked at xheo. It is easier to use and the documentation is better, but the price is substantially higher and here you can only get the user name in the license file that you then have to provide together with the unlock key. Could anyone share their experiences on what you are using and how it is working for you?
