• Git push origin master

  - by user306472

  I posted this question early yesterday, but the thread seems to have died out. For reference, see http://stackoverflow.com/questions/2619117/git-push-origin-master . Here's the low-down: I'm new to git. I just set up an account with github and I followed all their instructions flawlessly until I got to the last command of git push origin master Upon entering this command, I get the error message "fatal: No path specified. See 'man git-pull' for valid url syntax." If I type in git origin show the output I see is origin. If I type in git remote -n show the output is * remote origin URL: [email protected]: HEAD branch: (not queried) Local ref configured for 'git push' (status not queried): (matching) pushes to (matching) Please help me get to the bottom of this.

• Android and config.xml

  - by synic

  Looking in the android sdk folders, I've found a file called values/config.xml. This seems to be somewhere that you can define values for later use in layouts and animations. Given the config.xml: <resources> <string name="config_somePadding">50dip</string> </resources> How would I reference this to use as the layout_height in a layout xml file? @string/config_somePadding is actually the only one I've found that doesn't throw an error in Eclipse (even though there isn't a config_somePadding in values/strings.xml), but it appears to just put an empty string.

• debug javascript in release mode with yui compressions

  - by mickyjtwin

  In our build scripts, we are using YUI compressor to minify/compress javascript and css files. As this combines the js into one file, it needs to be referenced in the Master Layout script, e.g. First question is what is best way to use both, so that if we are developing (in debug mode) it will reference each js file individually? Second question, is once on production, would there be any steps/solution to debugging the javascript on the production server, i.e. conditionallly load the javascript files based on setting a "debug=true" setting in either js or .net?

• Is looping through the entityreference the correct way?

  - by Jova

  I want to get all users that have a specific role to a list of usernames. Is using .Include to include all the users, and going through the UsersReference the best way to loop through all the users that are associated with the role? I noticed I could not do a foreach(User user in role.Users) but UsersReference seem to work, but is that how it's supposed to be done? Going through the reference? using (var context = new MyEntities()) { List<string> users = new List<string>(); Role role = (from r in context.Roles.Include("Users") where r.RoleName == roleName select r).FirstOrDefault(); foreach (User user in role.UsersReference) users.Add(user.UserName); return users.ToArray(); }

• Change input text to regular text on blur and ability to edit jQuery

  - by eknown

  I'm creating a form where I'm eliminating the use of a save button. The form is made up of input text boxes and textareas. After the user enters data into the input field, I want to trigger an onBlur function and change the input into a span that contains the information that the user entered. I also want to have the ability to edit this information, so if the user clicks on the newly created span with text, it will turn back into the input field with the current information for their editing pleasure. For reference, I'm looking to have a functionality pretty much like on editing a photo title on Flickr. If possible, I'd also like to have the textbox show "saving..." for half a second after the blur to reflect interaction with server.

• Seam cache provider with ehcache null

  - by Cateno Viglio

  Hi every one, I'm trying to configure seam/ehcache following the tutorial from jboss page: http://docs.jboss.org/seam/2.1.2/reference/en-US/html/cache.html I put the ehcache.1.2.3.jar in project.ear/lib and injected CacheProvider as especified, but the CacheProvider always return null. The documentation doesn't show any aditional configuration for ehcache, just for jboss cache. I am probably doing something wrong, it's impossible be so easy :). besides put the jar in /lib, i created the following seam component to test: @Scope(ScopeType.SESSION) @Name("cacheBean") public class CacheSeamBean implements java.io.Serializable { @In(required=false, create=true) private EntityManager em; @Logger private Log log; @In private Events events; @In CacheProvider cacheProvider; Boolean blLoaded = Boolean.FALSE; @Create public void buscar() { if (!blLoaded){ List<Parametro> lstParametro = em.createQuery("select p from Parametro p").getResultList(); for (Parametro parametro : lstParametro){ cacheProvider.put(parametro.getCodigo(), parametro.getValor()); } blLoaded= Boolean.TRUE; } } } Thanks

• how to implement IOC without a global static service (non-service locator solution)?

  - by Michel

  Hi, we want to use Unity for IOC. All i've seen is the implementation that there is one global static service which holds a reference to the Unity container, which registers all interface/class combinations and every class asks that object: give me an implementation for Ithis or IThat. Frequently i see a response that this pattern is not good because it leads to a dependency from ALL classes to this service. But what i don't see often, is: what is the alternative way? Michel EDIT: found out that the global static service is called the service locator, added that to the title.

• Why don't web fonts in Firefox don't work on a different domain?

  - by mikez302

  I was experimenting with the fancy new OpenType font capability in Firefox 3.5 and I ran into a problem. I was trying to embed a font on a different domain than the page it would be used on, and it didn't work. I thought it may have been a bug, but from what I read on the MDC reference page, I noticed this note: In Gecko, web fonts are subject to the same domain restriction (font files must be on the same domain as the page using them), unless HTTP access controls are used to relax this restriction. It looks like they designed the browser that way on purpose. Out of curiosity, why would they do that? Is there any security risk with embedding a font? Or is it for legal trademark or copyright issues? Or something else?

• Spring - MVC - Sanitize URL before redisplaying to the user

  - by Raghav

  In my application , a HTTP GET request URL to the application with script tag is getting redisplayed as it is although it fails the authorization. Example: http://www.example.com/welcome<script>alert("hi")</script> The issue is sanitizing external input entered directly into address bar by modifying existing GET URL. Spring redisplays the submitted URL as it is. Though the script does not get executed in the browser(FF), is there anyway to strip the URL of these values before displaying it back to the user Reference: Spring MVC application filtering HTML in URL - Is this a security issue?

I make the object file like this: ld -r -b binary -o binary.o input.txt I then look objdump output to get the symbols: objdump -x binary.o And it gives symbols named: _binary_input_txt_start _binary_input_txt_end _binary_input_txt_size I then try and access them in my C program: #include <stdlib.h> #include <stdio.h> extern char _binary_input_txt_start[]; int main (int argc, char *argv[]) { char *p; p = _binary_input_txt_start; return 0; } Then I compile like this: gcc -o test.exe test.c binary.o But I always get: undefined reference to _binary_input_txt_start Does anyone know what I am doing wrong?

• Prototypes Object.extend with multiple objects that contain there own functions.

  How would I achieve something along the lines of this.. var Persistence = new Lawnchair('name'); Object.extend(Lawnchair.prototype, { UserDefaults: { setup: function(callback) { // "save" is a native Lawnchair function that doesnt //work because // "this" does not reference "Lawnchair" // but if I am one level up it does. Say if I defined // a function called UserDefaults_setup() it would work // but UserDefaults.setup does not work. this.save({key: 'key', value: 'value'}); // What is this functions scope? // How do I access Lawnchairs "this" } }, Schedule: { refresh: function(callback) { } } }); //this get called but doesnt work.

• Discussion: Working TDD in a Scrum context

  - by Anders Juul

  Hi all, When I work TDD I tend to start out with the big picture and create the tests that should succeed in order for the overall assignment to be completed - it then kicks off a number of supporting classes/methods/tests as I 'dig in'. If my assignment has been planned out in detail, I would then open one task, and in order to solve it, open another and then another. Only when the overall tests are succeeding can I close the original task, which means that at any given time, I would have a number of open tasks. I find that this approach conflict somewhat with the scrum approach where, ideally, I should be able to take and close a task within a day's work - and never have more than one task open at a time. I'm looking for input about how you manage this in your project - references to articles are also very welcome, I'm sure this has been debated thoroughly somewhere... The 'answer tick' will be awarded to best comment/reference. Thanks for any input, Anders, Denmark

• Using a single visual studio 2005 solution with multiple source control applications

  - by Bas Bossink

  In my recent SO question I was helped tremendously in using git as a front-end to ClearCase. However actually trying the suggested answer(s) led to further complications. Visual Studio keeps a reference to the used source control provider in both the .sln as well as the .csproj files. I tried resolving this issue by keeping a modified copy of the .sln with the source control provider paragraph removed but this did not help since each project also has some source control provider information. I don't want to keep private copies of all the projects since this would be a maintenance nightmare. Do any of you have suggestions on how to resolve this issue?

• Where Are the Release Versions of ASP.Net AJAX 4.0 Templating Files?

  - by Lee Richardson

  I'm trying to get the production version of ASP.Net AJAX 4.0 Templating working and can't find the JavaScript files. With the beta version I needed to reference MicrosoftAjaxTemplates.js, MicrosoftAjaxAdoNet.js, and MicrosoftAjaxDataContext.js. I can get everything to work with the beta CDN versions (e.g. http://ajax.microsoft.com/ajax/beta/0911/MicrosoftAjaxTemplates.js). But for the life of me I can't find 1. The release CDN versions of these files or 2. Where to download the whole Release ASP.Net AJAX 4.0 JavaScript package. The files certainly are not listed on the ASP.Net AJAX 4.0 CDN at http://www.asp.net/ajaxlibrary/CDNAjax4.ashx. Maybe the files have been renamed? Theoretically this should be a rediculously easy question and I'm a little embarrased to even ask it on StackOverflow, but I've had no luck finding an answer on my own. Any help would be much appreciated. Thanks, - Lee

• How to register System.DirectoryServices for use in SQL CLR User Functions?

  - by Saul Dolgin

  I am porting an old 32-bit COM component that was written in VB6 for the purpose of reading and writing to an Active Directory server. The new solution will be in C# and will use SQL CLR user functions. The assembly that I am trying to deploy to SQL Server contains a reference to System.DirectoryServices. The project does compile without any errors but I am unable to deploy the assembly to the SQL Server because of the following error: Error: Assembly 'system.directoryservices, version=2.0.0.0, culture=neutral, publickeytoken=b03f5f7f11d50a3a.' was not found in the SQL catalog. What are the correct steps for registering System.DirectoryServices on SQL Server?

• Java method overloading + double dispatch

  - by Max

  Can anybody explain in detail the reason the overloaded method print(Parent parent) is invoked when working with Child instance in my test piece of code? Any pecularities of virtual methods or methods overloading/resolution in Java involved here? Any direct reference to Java Lang Spec? Which term describes this behaviour? Thanks a lot. public class InheritancePlay { public static class Parent { public void doJob(Worker worker) { System.out.println("this is " + this.getClass().getName()); worker.print(this); } } public static class Child extends Parent { } public static class Worker { public void print(Parent parent) { System.out.println("Why this method resolution happens?"); } public void print(Child child) { System.out.println("This is not called"); } } public static void main(String[] args) { Child child = new Child(); Worker worker = new Worker(); child.doJob(worker); } }

• Why release the NSURLConnection instance in this statement?

  - by aquaibm

  I read this in a book. -(IBAction) updateTweets { tweetsView.text = @""; [tweetsData release]; tweetsData = [[NSMutableData alloc] init]; NSURL *url = [NSURL URLWithString:@"http://twitter.com/statuses/public_timeline.xml" ]; NSURLRequest *request = [[NSURLRequest alloc] initWithURL: url]; NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; [connection release]; [request release]; [activityIndicator startAnimating]; } In this statement,is that correct to release the "connection" instance at that time? After releasing it which means this NSURLConnection instance will be destroyed since it's reference count is 0 ,how are we going to make this connection operation work? THANKS.

• .NET interop COM DLL behaves differently in VB6 debugger

  - by Aheho

  I have a .NET v2.0 Dll that exposes a few classes to COM. The assembly is called BLogic.DLL I'm calling these classes from a legacy visual basic 6.0 application. I can generate and EXE file and if I have Blogic.dll in the same folder as the EXE, the program runs without a hitch. However If I try and launch the same program within the VB6 debugger I get a: Automation Error The system cannot find the file specified I assume when I'm running in the debugger, the PLogic.dll file can't be found. I tried putting it in the System32 folder, and the same folder as the VB6.EXE file, but I still get the same error. Other facts that may help: PLogic.dll is NOT a strongly-named assembly. It depends on a 3rd party reference that isn't strongly signed so VS doesn't let me strongly sign it. However the 3rd party functionality isn't being called by the VB6 code, and it is not ComVisible.

• ASP.NET application partially reading external configuration

  - by Trent

  I have an ASP.NET web app and am attempting to reference an external config (using enterprise application blocks configuration) for some of the configuration but it is not entirely working. I previously had all of the configuration info in the web.config (and it was working), but we are wanting to share some of this configuration information between multiple apps. When I put configurationSource tag in the web.config, and read the configuration through the WebConfigurationManager object, it loads some of the external config info (Logging) but not the connectionStrings and not the custom section I created. So its reading it (logging is working), but some dots aren't being connected and my connection strings aren't coming through. Again, it worked when it was all in the web.config. Any idea what needs to change to be able to reference an external configuration source and have it all come through?

• Signing an unsigned assembly

  - by dagda1

  The recent upgrade of NHibernate 2.1 has brought a mega headache situation to the surface. It seems most of the projects build by default as signed assemblies. For example fluentnhibernate references the keyfile fluent.snk. Nhibernate.search builds unsigned from what I can gather and will not build signed that is if you reference a generated keyfile, you get the error: Referenced assembly 'Lucene.Net' does not have a strong name This means projects like castle.activerecord that have nhibernate.search as a dependency will not build as you get the horrendous error referenced assembly nhibernate.search does not have a strong name: Quite a few projects use caslte.activerecord so it is quite important that this builds. Has anyone any idea what to do here as I am totally out of ideas? This is complete madness.

• URL Navigation and SQL Insertion After RadioButtonList Selection

  - by SidC

  Good Morning, I have a radiobuttonlist in my ASP.NET webforms application that is used as a voting tool. The concept is as follows: Users will vote for the blurb in the contentplaceholder using the radiobuttonlist. My list item values are 1 through 3 and my list item text is something like low, medium and high. Questions: 1. I want to save and accumulate votes for a given blurb. The blurb ID is referenced in a meta tag on the content page. How do I reference the meta tag in my SQL insert statement? 2. When the radiobuttonlist is used, can it cause the next content page to be loaded after the SQL insert is done? That is, I don't necessarily want the user to make the radiobuttonlist selection, then have to click a separate button to cast vote and move to next page. I want all that done in the radiobuttonlist. Is this possible? Thanks, Sid

• can I read exactly one UDP packet off a socket?

  - by Brian Palmer

  Using UNIX socket APIs on Linux, is there any way to guarantee that I read one UDP packet, and only one UDP packet? I'm currently reading packets off a non-blocking socket using recvmsg, with a buffer size a little larger than the MTU of our internal network. This should ensure that I can always receive the full UDP packet, but I'm not sure I can guarantee that I'll never receive more than one packet per recvmsg call, if the packets are small. The recvmsg man pages reference the MSG_WAITALL option, which attempts to wait until the buffer is filled. We're not using this, so does that imply that recvmsg will always return after one datagram is read? Is there any way to guarantee this? Ideally I'd like a cross-UNIX solution, but if that doesn't exist is there something Linux specific?

• Double encoded url being fully decoded in ASP.NET

  - by Brad R

  I have just come across something that is quite strange and yet I haven't found any mention on the interwebs of others having the same problem. If I hit my ASP.NET application with a double encoded url then the Request["myQueryParam"] will do a double decode of the query for me. This is not desirable as I have double encoded my query string for a good reason. Can others confirm I'm not doing something obviously wrong, and why this would happen. A solution to prevent it, without doing some nasty query string parsing, would be great too! As an example if you hit the url: http://localhost/MyApp?originalUrl=http%3a%2f%2flocalhost%2fAction%2fRedirect%3fUrl%3d%252fsomeUrl%253futm_medium%253dabc%2526utm_source%253dabc%2526utm_campaign%253dabc (For reference %25 is the % symbol) Then look at the Request["originalUrl"] (page or controller) the string returned is: http://localhost/Action/Redirect?Url=/someUrl?utm_medium=abc&utm_source=abc&utm_campaign=abc I would expect: http://localhost/Action/Redirect?Url=%2fsomeUrl%3futm_medium%3dabc%26utm_source%3dabc%26utm_campaign%3dabc I have also checked in Fiddler and the URL is being passed to the server correctly (one possible culprit could have been the browser decoding the URL before sending).
