• Android Source code download error

  - by user351850

  Hi all I have followed the instructions on the Android website on how to download the latest android source code files but it gives errors when i run this command: repo init -u git://android2.git.kernel.org/platform/manifest.git It gives the following error: Getting repo ... from git://android.git.kernel.org/tools/repo.git android.git.kernel.org[0: 199.6.1.176]: errno=Connection refused android.git.kernel.org[0: 130.239.17.12]: errno=Connection refused fatal: unable to connect a socket (Connection refused) On checking forums for its resolution, i was told that port 9418 was being blocked. I use Ubuntu 10.04 and ensured that the firewall wasnt blocking the port and also enabled the port and the above IP addresses. I also spoke to the networking peeps who ensured that no traffic from the internet is being blocked. I would be glad if i could get directions on how to proceed next. Many thanks as you respond.

• Missing something with Reader monad - passing the damn thing around everywhere

  - by Richard Huxton

  Learning Haskell, managing syntax, have a rough grasp of what monads etc are about but I'm clearly missing something. In main I can read my config file, and supply it as runReader (somefunc) myEnv just fine. But somefunc doesn't need access to the myEnv the reader supplies, nor do the next couple in the chain. The function that needs something from myEnv is a tiny leaf function. So - how do I get access to the environment in a function without tagging all the intervening functions as (Reader Env)? That can't be right because otherwise you'd just pass myEnv around in the first place. And passing unused parameters through multiple levels of functions is just ugly (isn't it?). There are plenty of examples I can find on the net but they all seem to have only one level between runReader and accessing the environment.

• Knowing the fundamentals of Java what is the right approach to learn Groovy?

  - by Liuh

  As my question already implies I want to learn a new language and have read several articles about groovy and its more pragmatic syntax. SO I have choosen Groovy as the language of my choice. What is a good way to learn a new language like Groovy when I already know the fundamentals of Java. When I understand correctly Groovy will be running in the Java Virtual Machine and allows me to always rely on what I know from Java when I don't know how to solve the problem in Groovy. I am looking for hints on how to organize a learning track to learn this language. I found that page explaining the differences: http://groovy.codehaus.org/Differences+from+Java But what I am looking for is more a tutorial where I can get through and get introduced to the differences.

• Is there a function that can read a php function post-parsing?

  - by Rob

  I've got a php file echoing hashes from a MySQL database. This is necessary for a remote program I'm using, but at the same time I need my other php script opening and checking it for specified strings POST parsing. If it checks for the string pre-parsing, it'll just get the MySQL query rather than the strings to look for. I'm not sure if any functions do this. Does fopen() read the file prior to parsing? or file_get_contents()? If so, is there a function that'll read the file after the php and mysql code runs? The file with the hashes query and echo is in the same directory as the php file reading it, if that makes a difference. Perhaps fopen reads it post-parse, and I've done something wrong, but at first I was storing the hashes directly in the file, and it was working fine. After I changed it to echo the contents of the MySQL table, it bugged out.

• ASP.NET request extension type

  - by Krishna

  Hello, I am working on a large web application which I have recently shelved tons of .aspx pages from the project. To avoid page not found error, I added these entities in the xml which came around 300+ in count. I wrote a http module that checks the request url in the xml entities and if they are found, my module is going to redirect the request to respective new pages. Everything works great, but my collection is getting iterated for all the requests, I mean for each and every .jpg, .css, .js, .ico, .pdf etc. Is there any object or property in .net that can tell the type of request that user requested for like HttpContext.request.type. So that I can avoid checking the request for all unwanted file types.

• Firefox HTML5 video playback inconsistancy

  - by Daniel Redwood

  Hey all, I've got an HTML5 video on a page. When tested locally, Chrome, Safari, and Opera work beautifully. Firefox plays it, but doesn't loop as efficiently as the others. The real problem is when it's tested off a server. Firefox doesn't play the video, but recognizes there is one there. I was wondering if all that open ended three-different-ways syntax can be swung in Firefox's favor. Thanks! HTML: <video id="vid_home" width="780" height="520" autoplay="autoplay" loop="loop"> <source src="Video/fernando.ogv" type="video/ogg" /> <source src="Video/fernando.m4v" type="video/mp4" /> Your browser does not support this videos playback. </video>

• Add Attribute (System.Attribute variety) to .aspx page - not the code-behind

  - by Macho Matt

  I am creating a custom Attribute (extending System.Attribute). I know I can put it on another class easily enough by doing the following. [MattsAttribute] public class SomeClassWhichIsACodeBehind { However, I need to be able to test this attribute easily, and putting it in the code-behind would cause a lot of extra effort to get it deployed to an environment which would respond to the behavior of attribute. What I would like to do: declaratively apply this attribute to the .aspx page itself (which is really just another class that inherits from the code-behind). Is this possible? If so, what is the proper syntax for doing this?

• Why cant i add Orientation property to the style setter in WPF

  - by nihi_l_ist

  When i write something like this: <Style x:Key="panelS"> <Setter Property="Orientation" Value="Horizontal" /> <Setter Property="DockPanel.Dock" Value="Top" /> </Style> I get the error that says: Cannot resolve the Style Property 'Orientation'. Verify that the owning type is the Style's TargetType, or use Class.Property syntax to specify the Property. Sure i have a Dock panel with many Stackpanels in it so i want to move Stackpanel's properties to the style. But there is this error and i dont quite understand what it means and what is the workaround(..i'd wanted not to assign Orientation on every Stackpanel).

• rails - form to disply non-input type fields in nested form

  - by nktokyo

  Hi, I guess this is a newbie question, but what is the syntax in a form to show contents of fields not as a text box/area, but rather like label would appear. <% form_for @user do |f| %> <% f.fields_for :user_ingreds do |builder| %> <p> <%= builder.??? %> </p> <% end %> <% end%> user has many user_ingreds and accepts_nested_attributes for user_ingreds. Basically I want to make a list of user_ingreds where the user can't edit the data but can remove the record from the list via a button - however the fields_for builder doesn't recognize a direct call to to the fields in user_ingreds model (ie, builder.user_id throws and error.

• Does any language have a while-else flow structure?

  - by dotancohen

  Consider this flow structure which I happen to use often: if ( hasPosts() ) { while ( hasPosts() ) { displayNextPost(); } } else { displayNoPostsContent(); } Are there any programming languages which have an optional else clause for while, which is to be run if the while loop is never entered? Thus, the code above would become: while ( hasPosts() ) { displayNextPost(); } else { displayNoPostsContent(); } I find it interesting that many languages have the do-while construct (run the while code once before checking the condition) yet I have never seen while-else addressed. There is precedent for running an N block of code based on what was run in N-1 block, such as the try-catch construct. I wasn't sure whether to post here or on programmers.SE. If this question is more appropriate there, then please move it. Thanks.

• FileNotFoundException when using FileInputStream

  - by user1672817

  I am trying to access a file I have contained in the jar. The beginning of my code is as follows: import java.io.*; import java.net.*; public class intro { public static void main(String[] args) throws IOException{ URL jarUrl = intro.class.getResource("myFile.jar"); File myJar = new File(jarUrl.toString()); FileInputStream fis = new FileInputStream(myjar); } I'm getting the following error: Exception in thread "main" java.io.FileNotFoundException: file:\...myFile.jar (The filename, directory name, or volume label syntax is incorrect) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(Unknown Source) at intro.main(intro.java:10) It seems to have no problem finding the URL or initializing the file, but I can't get the FileInputStream to work. Does anybody know what I'm doing wrong? Help would be appreciated.

• Enumerating all hamiltonian paths from start to end vertex in grid graph

  - by Eric

  Hello, I'm trying to count the number of Hamiltonian paths from a specified start vertex that end at another specified vertex in a grid graph. Right now I have a solution that uses backtracking recursion but is incredibly slow in practice (e.g. O(n!) / 3 hours for 7x7). I've tried a couple of speedup techniques such as maintaining a list of reachable nodes, making sure the end node is still reachable, and checking for isolated nodes, but all of these slowed my solution down. I know that the problem is NP-complete, but it seems like some reasonable speedups should be achievable in the grid structure. Since I'm trying to count all the paths, I'm sure that the search must be exhaustive, but I'm having trouble figuring out how to prune out paths that aren't promising. Does anyone have some suggestions for speeding the search up? Or an alternate search algorithm?

• Mod_rewrite with multiple variables

  - by Andrei

  Hello, I'm using a PHP script that dynamically generates transparent PNGs for use as CSS backgrounds from a query string that takes RGBa and HSLa values. The original script can be found here, I've only added HSLa support. Because background URLs with PHP query strings aren't very pretty, and because it seems to break the IE 6 transparent PNG hack, I thought of using mod_rewrite to allow the script to be called when a .png with this syntax is called : /assets/colors/h[0-360 value]_s[0-100 value]_l[0-100 value]_a[0-100 value].png which would be rewritten to : /assets/colors.php?h=[0-360 value]&s=[0-100 value]&l=[0-100 value]&a=[0-100 value] Here's the issues I'm encountering : passing multiple variables with mod_rewrite using an underscore as a delimiter I know this could be done by passing a single variable and then exploding it in the PHP script, however I would prefer it to be done by Apache. Thanks in advance and if anyone wants my HSLa enabled version of the script just ask. Anyway I recommend you check it out on it's author's website.

• Most efficient way for testing links

  - by Burnzy

  I'm currently developping an app that is going through all the files on a server and checking every single hrefs to check wether they are valid or not. Using a WebClient or a HttpWebRequest/HttpWebResponse is kinda overkilling the process because it downloads the whole page each time, which is useless, I only need to check if the link do not return 404. What would be the most efficient way? Socket seems to be a good way of doing it, however I'm not quite sure how this works. Thanks for sharing your expertise!

• Enums With Default Throw Clause?

  - by Tom Tresansky

  I noticed the following in the Java Language spec in the section on enumerations here: link switch(this) { case PLUS: return x + y; case MINUS: return x - y; case TIMES: return x * y; case DIVIDE: return x / y; } throw new AssertionError("Unknown op: " + this); However, looking at the switch statement definition section, I didn't notice this particular syntax (the associated throw statement) anywhere. Can I use this sort of "default case is throw an exception" syntactic sugar outside of enum definitions? Does it have any special name? Is this considered a good/bad practice for short-cutting this behavior of "anything not in the list throws an exception"?

• Which are the best techniques to protect a 'homemade' framework from unlogged visitors?

  - by Hermet

  First of all, I would like to say that I have used the search box looking for a similar question unsuccessfully, maybe because of my poor english skills. The way I currently do this is checking in every single page that a session has been opened. If not, the user gets redirected to a 404 page, to seem like the file which has been requested doesn't exist. I really don't know if this is sure or there's a better and more safety way and I'm currently working with kind of confidential data that should never become public. Could you give me some tips? Or leave a link where I could find some? Thank you very much, and again excuse me for kicking the dictionary.

• Drupal 6 devel module dd() function not writing to drupal_debug.txt file

  - by Mike Munroe

  I am running a local development Drupal site on a Windows machine. I am trying to use the dd($data, $label = NULL) function from the devel module to help debug. Using this function, should write debug info to a drupal_debug.txt file in the /tmp folder on the machine where the Drupal site is hosted. On my Windows machine, although I am using this function, the drupal_debug.txt file is not getting created anywhere, leading me to believe I am using the function incorrectly. Here is a snippet of how I am using it, <?php $test = "this is my test"; dd($test, $label = NULL); I am looking for an example of the correct syntax for the dd($data, $label = NULL) function. I have the Devel module enabled.

• remove spaces in string using javascript

  - by reza saberi

  I need to do some functions on some text field contents before submitting the form, like checking the validity of the customer registeration code, having the customer name as his code in customers table appending an incrementing number. I don't want to do it after the form is submitted becuase I need it to be displayed in the code field before submitting the form. My code: function getCode(){ var temp = document.getElementById("temp").value ; var d = parseInt(document.getElementById("temp").value) + 1; document.getElementById("customernumber").value = d; document.getElementById("code").value = document.getElementById("name").value+"-"+ d; } It all works fine, but the last line of code developed the code WITH the spaces between the code.

• Which file is the COM++ object and how do I import it to .NET?

  - by Bad Man

  I'm trying to write a COM++ object wrapper around a Qt widget (control) I wrote so I can use it in future .NET projects. e.g.: public __gc class comWidget; In the compile directory are the .exe, an exe.intermediate.manifest, and the comWidget.obj, and also some other crap files (.pdb, etc). So what/how do I import into .NET? I feel like I'm missing an important step for registering the object or whatever, but all these tutorials are terrible outdated and ridiculously unhelpful (for instance, I'm using the old CLR syntax because I can't find any good docs on the new stuff, thx again M$ for being lazy faggots as usual)

• define method for instance of class

  - by aharon

  Let there be class Example defined as: class Example def initialize(test='hey') self.class.send(:define_method, :say_hello, lambda { test }) end end On calling Example.new; Example.new I get a warning: method redefined; discarding old say_hello. This, I conclude, must be because it defines a method in the actual class (which makes sense, from the syntax). And that, of course, would prove disastrous should there be multiple instances of Example with different values in their methods. Is there a way to create methods just for the instance of a class from inside that instance? Thanks so much.

• Multiple resultsets from Oracle in Odp.net,without refcursors

  - by James L

  SQL Server is able to return the results of multiple queries in a single round-trip, e.g: select a, b, c from y; select d, e, f from z; Oracle doesn't like this syntax. It is possible to use reference cursors, like this: begin open :1 for select count(*) from a; open :2 for select count(*) from b; end; However, you incur a penalty in opening/closing cursors and you can hold database locks for an extended period. What I'd like to do is retrieve the results for these two queries in one shot, using Odp.net. Is it possible?

• How to make form validation in Django dynamic?

  - by Oli

  I'm trying to make a form that handles the checking of a domain: the form should fail based on a variable that was set earlier in another form. Basically, when a user wants to create a new domain, this form should fail if the entered domain exists. When a user wants to move a domain, this form should fail if the entered domain doesn't exist. I've tried making it dynamic overload the initbut couldn't see a way to get my passed variabele to the clean function. I've read that this dynamic validation can be accomplished using a factory method, but maybe someone can help me on my way with this? Here's a simplified version of the form so far: #OrderFormStep1 presents the user with a choice: create or move domain class OrderFormStep2(forms.Form): domain = forms.CharField() extension = forms.CharField() def clean(self): cleaned_data = self.cleaned_data domain = cleaned_data.get("domain") extension = cleaned_data.get("extension") if domain and extension: code = whoislookup(domain+extension); #Raise error based on result from OrderFormStep1 #raise forms.ValidationError('error, domain already exists') #raise forms.ValidationError('error, domain does not exist') return cleaned_data

• Optional parens in Ruby for method with uppercase start letter?

  - by RasmusKL

  I just started out using IronRuby (but the behaviour seems consistent when I tested it in plain Ruby) for a DSL in my .NET application - and as part of this I'm defining methods to be called from the DSL via define_method. However, I've run into an issue regarding optional parens when calling methods starting with an uppercase letter. Given the following program: class DemoClass define_method :test do puts "output from test" end define_method :Test do puts "output from Test" end def run puts "Calling 'test'" test() puts "Calling 'test'" test puts "Calling 'Test()'" Test() puts "Calling 'Test'" Test end end demo = DemoClass.new demo.run Running this code in a console (using plain ruby) yields the following output: ruby .\test.rb Calling 'test' output from test Calling 'test' output from test Calling 'Test()' output from Test Calling 'Test' ./test.rb:13:in `run': uninitialized constant DemoClass::Test (NameError) from ./test.rb:19:in `<main>' I realize that the Ruby convention is that constants start with an uppercase letter and that the general naming convention for methods in Ruby is lowercase. But the parens are really killing my DSL syntax at the moment. Is there any way around this issue?
