• Is git svn rebase required before git svn dcommit?

  - by allyourcode

  I'm reading about using git as an svn client here: http://learn.github.com/p/git-svn.html That page suggests that you do git svn rebase before git svn dcommit, which makes perfect sense; it's like doing svn update before doing svn commit. Then, I started looking at the documentation for git svn dcommit (I was wondering what the 'd' is about): http://www.kernel.org/pub/software/scm/git/docs/git-svn.html You have to scroll down a bit to see the documentation on dcommit, which says this: Commit each diff from a specified head directly to the SVN repository, and then rebase or reset (depending on whether or not there is a diff between SVN and head). This confuses me, because if you do as the first page says, there will be no changes to pull down from svn once the first part of dcommit finishes. I'm also confused by the part that talks about reset; isn't git reset for removing changes from the staging area? Why would rebase or reset follow (the first part of) a dcommit?

• Problem evaluating NULL in an IIF statement (Access)

  - by Mohgeroth

  Item in the recordset rstImportData("Flat Size") is = Null With that, given the following statement: IIF(IsNull(rstImportData("Flat Size")), Null, cstr(rstImportData("Flat Size"))) Result: Throws error 94: Invalid use of Null If I change the statement by removing the type conversion upon a false comparison: IIF(IsNull(rstImportData("Flat Size")), Null, 0) Result: Null It returns Null as it should have the first time. It appears that I cannot do a type conversion in an IIF if the value passed in should ever be null even if it passes an IIF test, it still attempts to evaluate it at both the true and false answer. The only reason I'm using IIF like this is because I have a 25 line comparison to compare data from an Import against a matching record in a database to see if I need to append the prior to history. Any thoughts? The way data is imported there will be null dates and where the spreadsheet import is in a string format I must convert either side to the other to compare the values properly but if either side is null this exception occurs :(

• Extending LINQ classes to my own partial classes in different namespaces?

  - by sah302

  I have a .dbml file which of course contains the auto-generated classes based on my tables. I would however, like to extend them to my own classes. Typically I design such that each of my tables get their own namespace in their own folder containing all of their associated dao and service classes. So if I am dealing with a page that only has to do with 'customers' for instance, I can only include the customerNS. But when using LINQ I seem to be unable to do this. I have tried removing a default namespace from the project, I have tried putting the .dbml file into it's own folder with a custom namespace and then adding a 'using' statement, but no nothing works. I also saw the Entity Namespace, Context Namespace, and Custom Tool Namespace properties associated with the .dbml file and tried setting all these to names x and trying 'using x' in my other class to allow me to extend partial classes, but it just doesn't work. Is this possible or do I have to keep all extended partial classes in the same namespace as the .dbml file?

• Zend_Cache_Backend_Sqlite vs Zend_Cache_Backend_File

  - by Alekc

  Hi, Currently i'm using Zend_Cache_Backend_File for caching my project (especially responses from external web services). I was wandering if I could find some benefit in migrating the structure to Zend_Cache_Backend_Sqlite. Possible advantages are: File system is well-ordered (only 1 file in cache folder) Removing expired entries should be quicker (my assumption, since zend wouldn't need to scan internal-metadatas for expiring date of each cache) Possible disadvantages: Finding record to read (with files zend check if file exists based on filename and should be a bit quicker) in term of speed. I've tried to search a bit in internet but it seems that there are not a lot of discussion about the matter. What do you think about it? Thanks in advance.

• MPMoviePlayerController switching movies causes white flash

  - by bennythemink

  Hi guys, I have a small UIView that displays a repeated movie. When the user taps a button another movie is loaded and displayed in the same UIView. The problem is that there is a half second "flash" between the removing of the first movie and the displaying of the second. Is there any to remove this? <code> - (void) setUpMovie:(NSString*)title { NSString *url = [[NSBundle mainBundle] pathForResource:title ofType:@"mp4"]; MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:url]]; [[player view] setFrame:self.movieView.bounds]; [self.movieView addSubview:player.view]; if ([title isEqualToString:@"Bo_idle_02"]) { [player setRepeatMode:MPMovieRepeatModeOne]; } else { [player setRepeatMode:MPMovieRepeatModeNone]; } [player setControlStyle:MPMovieControlStyleNone]; [player play]; } - (void) startDanceAnimation { [self setUpMovie:@"Bo_dance_02"]; return; } </code>

• How do i keep my DB and lucene in sync?

  - by acidzombie24

  So i can have a transaction in sql. But i am sure its not a good idea to wait in the middle of a transaction for lucene to finish also i am unsure if lucene is permanently saved in the DB until i do something there. Whats the best way to keep my DB and lucene in sync? I am thinking of adding a lucene_queue in my sql db and everytime i make a change i add it into the queue (removing older queue if any) and delete it once it is done. Is this the best way? Also i am unsure how to make lucene permanently keep the changes i made and how frequent i can/should do it.

• java runtime tracing library to replace system.out.println

  - by Grzegorz Oledzki

  Have you heard of any library which would allow me to set up a tracing for specific methods at runtime? Instead of adding (and removing) lots of System.out.println in my code (and having to re-compile and re-deploy) I would like to have a magic thing which would print out a line for each call of selected method without any change in the code. This would work without re-compiling, so some kind of JVM agent (or some non-standard JVM would be needed?). Sounds like a job for aspect programming? A typical scenario would be to start an application, configure the traced methods dynamically (in a separate file or similar) and then everytime a selected method is called a line with its name (and arguments) is printed out to System.out (or some log file). Naturally one could think of tens of additional features, but this basic set would be a great tool. BTW, I use Eclipse interactive debugger too, not only the System.out tracing technique, but both have some advantages and sometimes Eclipse is not enough.

• Calling UITableViews delegate methods directly.

  - by RickiG

  Hi I was looking for a way to call the edit method directly. - (void)tableView:(UITableView *)theTableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath I have all my logic for animating manipulated cells, removing from my model array etc. in this method. It is getting called when a user swipes, adds or rearranges, but I would like to call it manually/directly as a background thread changes my model. I have constructed an NSIndexPath like so: NSIndexPath *path = [NSIndexPath indexPathForRow:i inSection:1]; I just can't figure out how to call something like: [self.tableview commitEditingStyle:UITableViewCellEditingStyleDelete forRowAtIndexPath:path]; Do I need to gain access to the methods of this plain style UITableView in another way? Thanks:)

• assistance with classifying tests

  - by amateur

  I have a .net c# library that I have created that I am currently creating some unit tests for. I am at present writing unit tests for a cache provider class that I have created. Being new to writing unit tests I have 2 questions These being: My cache provider class is the abstraction layer to my distributed cache - AppFabric. So to test aspects of my cache provider class such as adding to appfabric cache, removing from cache etc involves communicating with appfabric. Therefore the tests to test for such, are they still categorised as unit tests or integration tests? The above methods I am testing due to interacting with appfabric, I would like to time such methods. If they take longer than a specified benchmark, the tests have failed. Again I ask the question, can this performance benchmark test be classifed as a unit test? The way I have my tests set up I want to include all unit tests together, integration tests together etc, therefore I ask these questions that I would appreciate input on.

• Perl: Unsuccessful stat on filename containing newline. What?

  - by Daniel

  Hello, I am getting an error I do not understand. I am using File:find to recurse a fylesystem on windows using Activestate Perl 5.8.8 and trying to stat $File::Find::name; so I am not stat-ing a filename got from a text file scanning requiring chomp-ing or newline removing. I was unable to get file modification time, the m in: my ($dev,$ino,$mode,$nlink,$uid,$gid,$rdev,$size,$atime,$mtime,$ctime,$blksize,$blocks) = stat($File::Find::name); so trying a -s $File::Find::name give me the error: "Unsuccessful stat on filename containing newline" A typical file name found is F01-01-10 Num 0-00000.pdf but I get the same error even renaming in E02.pdf Some ideas about a possible reason for this error?

• Configuring Warden for use in RSpec controller specs

  - by Chris Peters

  I was able to use Devise's sign_in method to log in a user in my controller specs. But now that I'm removing Devise from my application, I'm not quite sure how to get similar functionality working with just Warden on its own. How should I go about setting up spec/spec_helper.rb and related spec/support/*.rb files to get Warden running within controller specs sufficiently? I've tried setting up a file at spec/support/warden.rb with these contents: RSpec.configure do |config| config.include Warden::Test::Helpers config.after do Warden.test_reset! end end Then I have before calls similar to this to authenticate a user factory: before { login_as FactoryGirl.create(:user) } But here is the error that I keep seeing: NameError: undefined method `user' for nil:NilClass This error traces back to my authenticate_user! method in the controller: def authenticate_user! redirect_to login_path, notice: "You need to sign in or sign up before continuing." if env['warden'].user.nil? end I'd appreciate any guidance that anyone could provide.

• tidy/efficient function writing in R

  - by romunov

  Excuse my ignorance, as I'm not a computer engineer but with roots in biology. I have become a great fan of pre-allocating objects (kudos to SO and R inferno by Patrick Burns) and would like to improve my coding habits. In lieu of this fact, I've been thinking about writing more efficient functions and have the following question. Is there any benefits in removing variables that will be overwritten at the start of the next loop, or is this just a waste of time? For the sake of argument, let's assume that the size of old and new variables is very similar or identical.

• min.js to clear source

  - by dole

  Hi there As far i know until now, the min version of a .js(javascript) file is obtaining by removing the unncessary blank spaces and comments, in order to reduce the file size. My questions are: How can I convert a min.js file into a clear, easy readable .js file Besides, size(&and speed) are there any other advtages of the min.js file. the js files can be encripted? can js be infected. I think the answer is yes, so the question is how to protect the .js files from infections? Only the first question is most important and I'm looking for help on it. TY

• "import as" leads to unresolved import error, "from .. import" does not

  - by Markus R.

  I'm trying to write some plugins for the irc bot supybot with eclipse/pydev. Pydev gives me errors about unresolved imports on supybot-modules/packages (e. g. import supybot.utils as utils), but works ok on e. g. "from supybot.commands import *". So I guess I set up dydev correctly, as it finds the wanted modules. The problem must be in pydev/eclipse, as the bot works correct and in eric5 I get also no errors about that. Removing the interpreter and setting it up didn't help. Any other ideas on how to fix this? System: Arch Linux, Eclipse Juno, PyDev 2.7.1, wanted (and set up) python interpreter is 2.7, supybot is installed in site-packages for Python 2.7. Edit: Just noticed: PyDev doesn't mark the "from ... import *" as error, but if I use functions imported from there I get an error on that function.

• Django comments form validation, check if the comment is from authenticated user

  - by Headcrab

  I wanted to add reCaptcha to the comment form, but only for non-authenticated users. I've created my own comments app, using reCaptcha more or less according to this post, except that I don't have any (explicit) view function to post the comment, but instead I check captcha as a part of form validation process. Everything works fine so far. Now, how do I disable reCaptcha for a logged in user? Removing all reCaptcha-related fields in the template is no problem, but how do I validate the form, not checking captcha if the comment if from an authenticated user? Alternatively, is there a way to use two different comment form classes, depending on whether the user is authenticated or not?

• PHP namespaces and using the \ prefix in declaration

  - by Jason McCreary

  The following throws an error stating Exception can no be redeclared. namespace \NYTD\ReadingListBackend; class Exception extends \Exception { } However, removing the \ prefix in the namespace declaration does not: namespace NYTD\ReadingListBackend; I recently adopted PHP namespaces. My understanding is that namespaces prefixed with \ are a fully qualified name. So why can't I use the prefix in the namespace declaration? I can when referencing (e.g. new \NYTD\ReadingListBackend\Exception). Would appreciate a full explanation as I couldn't find anything in the docs.

• jQuery click event to make a div slide down and push next div out of viewport

  - by Josh

  I'm trying to figure out how to make jQuery slide #content2 down and replace content1 with it while making it look like #content1 is actually being pushed down by #content1 removing it from view... Then the same button that was clicked to make #content2 replace #content1 would also need to do the reverse effect by replacing #content2 with #content1 making them slide up and push each other out of the way... I'm not all that great with jQuery so I'm sure I've gone about this the wrong way, but here's what I've tried: $(document).ready(function() { $('#click').click(function() { if($('#content1').is(':visible')) { $('#content1').slideUp(); } else { $('#content2').slideDown(); } }).click(function() { if($('#content1').is(':visible')) { $('#content2').slideDown(); } else { $('#content1').slideUp(); } }); });

• How to force a node inside tiny mce ?

  - by KutePHP

  Hi All, I'm using tiny mce for my project and want to validate the node inside the tiny mce. On click of a text element, let's say a paragraph with some id, I load editor for the element. But, sometimes if user replaces the whole content, the node and its HTML is lost. I want to retain this node and only the content is removed. The node can be a paragraph or heading or ul or ol. EDIT : I'm providing dummy text such as "Lorem epsum .....". User will be removing this dummy text and add his content. How can I accomplish this ?

• NavBar displaying back twice when app changed to landscape mode

  - by Graeme

  Hi, Not sure what's going on here, but my iPhone apps nav bar shows back and the title of my detail view controller even when I'm back to the original view. It wasn't happening earlier, it has changed recently (but not sure when exactly). E.g. I click on a row, view the didSelectRow XIB and then click back on the NavBar controller, but it still shows back even though the view does change back to the original table view. I then have to press back again and then it clears. Update: It's as if its trying to go back three times instead of two. Because, if you visit another row without removing the back button, it stores it as if you need to go back twice. It works fine in portrait mode. Any ideas?

• Formatting a query to enumerate through 2 different datatables

  - by boiler1974

  I have 2 datatables sendTable and recvTable They both have identical column names and numbers of columns "NODE" "DSP Name" "BUS" "IDENT" "STATION" "REF1" "REF2" "REF3" "REF4" "REF5" "REF6" "REF7" "REF8" I need to compare these 2 tables and separate out the mismatches I only need to check Columns 3-11 and Ignore col 1 and 2 I tried at first removing the 2 columns and then loop thru row by row and return matches and mismatches but the problem with this approach is that I no longer have the "NODE" and "DSP Name" associated with the row when I finalize my results So I need help with a query Here is my attempt var samerecordQuery = from r1 in sendTable.AsEnumerable() where r1.Field<int>("BUS").Equals(from r2 in recvTable.AsEnumerable() where r2.Field<int>("BUS")) this obviously doesn't work so how do I format the query to say from r1 cols[3-11] equals r2 cols [3-11] and once I have this I can use the except to pull out the mismatches

• Help: My SSL Certificate expired but I can't renew it until Monday, is there any way I can disable SSL through IIS?

  - by Ryan

  Or perhaps force redirect to HTTP when they request HTTPS? I tried removing the SSL port settings under 'Advanced' but it broke the login page. I don't want to do a deploy/recompile right now but I am able to edit the VIEWS. However I am thinking there may be a way for IIS to do this, but then again I think the .NET code tries to force SSL. And yes, the key is that more support tickets will be caused by the browser giving a security error than if SSL was removed entirely for one day. Becaues they wouldn't very very likely not notice it being gone.

• How to make a thread try to reconnect to the Database x times using JDBCTemplate

  - by gillJ

  Hi, I have a single thread trying to connect to a database using JDBCTemplate as follows: JDBCTemplate jdbcTemplate = new JdbcTemplate(dataSource); try{ jdbcTemplate.execute(new CallableStatementCreator() { @Override public CallableStatement createCallableStatement(Connection con) throws SQLException { return con.prepareCall(query); } }, new CallableStatementCallback() { @Override public Object doInCallableStatement(CallableStatement cs) throws SQLException { cs.setString(1, subscriberID); cs.execute(); return null; } }); } catch (DataAccessException dae) { throw new CougarFrameworkException( "Problem removing subscriber from events queue: " + subscriberID, dae); } I want to make sure that if the above code throws DataAccessException or SQLException, the thread waits a few seconds and tries to re-connect, say 5 more times and then gives up. How can I achieve this? Also, if during execution the database goes down and comes up again, how can i ensure that my program recovers from this and continues running instead of throwing an exception and exiting?

• How to create Bitmap object from a Graphics object ?

  - by vi.su.

  How to create Bitmap object from a Graphics object ? I would like to read pixels from my Graphics object. for example, like, System.Drawing.BitMap.GetPixel(). I am trying to find out empty area (all white, or of any colour) inside a pdf document, to write some graphics / image. I have tried like this, but it is not working. why the following code is not working as expected ? // // System.Drawing.Bitmap // System.Drawing.Graphics // Bitmap b = new Bitmap(width, height, graphics); // // In this case, for any (i, j) values, Bitmap.GetPixel returns 0 // int rgb = b.GetPixel(i, j).ToArgb(); ( posting this question again in .net-only context, removing other library dependencies )

• How can I work with paragraphs in Wordpress?

  - by Steven

  Wordpress has a filter that automatically add paragraphs to posts. I can remove this by adding the followin code: // Remove the <p> tags which WP automatically inserts in psots. remove_filter ('the_content', 'wpautop'); The problem is that i removes <br /> tags as well. So I'm not removing this filter at the moment. My problem is that inside a DIV box, I get extra space above and below the text (at the start / end of text). I could manipulate the <p> tag in css, but again, that will affect all <p> tags throughout the post content. Any suggestions to what I should do?

• Implicit declaration when using a function before it is defined in C, why can't the compiler figure this out?

  - by rolls

  As the title says, I know what causes this error but I want to know why the compiler gives it in this circumstance. Eg : main.c void test(){ test1(); } void test1(){ ... } Would give an implicit declaration warning as the compiler would reach the call to test1() before it has read its declaration, I can see the obvious problems with this (not knowing return type etc), but why can't the compiler do a simple pass to get all function declarations, then compile the code removing these errors? It just seems so simple to do and I don't believe I've seen similar warnings in other languages. Does anyone know if there is a specific purpose for this warning in this situation that I am overlooking?
