  • Indexing one-dimensional numpy.array as matrix

    - by Alain
    I am trying to index a numpy.array with varying dimensions during runtime. To retrieve e.g. the first row of a n*m array a, you can simply do a[0,:] However, in case a happens to be a 1xn vector, this code above returns an index error: IndexError: too many indices As the code needs to be executed as efficiently as possible I don't want to introduce an if statement. Does anybody have a convenient solution that ideally doesn't involve changing any data structure types?

  • SSIS to copy data from one table to another, where not in destination table

    - by alex
    I'm in the process of creating an SSIS package on a server (server1) that looks at the data in a sql db on another site (server2) and copies relevant rows across. The SQL statement required is: SELECT * FROM server2.ordersTable WHERE OrderID Not In (SELECT OrderID FROM server1.ordersTable This selects data from server1 which isn't in the table on server2 (based on order id) I then need to insert the result into a table on server1 How would I approach this? What components do I need etc...?

  • Randomised objects are assigning themselves to more than one array location

    - by Thaddeus Aid
    this.size = 9; this.populationSize = 10; Random rand = new Random(); Integer[][] easy1 = new Integer[size][size]; easy1 = this.initializeEasy1(easy1); this.sudokuArray = new Sudoku[this.populationSize]; for (int i = 0; i < this.sudokuArray.length; i++){ long seed = rand.nextLong(); System.out.println("" + seed); this.sudokuArray[i] = new Sudoku(easy1, this.size, seed); } I am building an evolutionary sudoku solver and I am having a problem where the last Sudoku object is overwriting all the other objects in the array. Where in the code did I mess up? /edit here is the constructor of the class public Sudoku(Integer[][] givensGrid, int s, long seed){ this.size = s; this.givens = givensGrid; this.grid = this.givens.clone(); Random rand = new Random(seed); System.out.println("Random " + rand.nextInt()); // step though each row of the grid for (int i = 0; i < size; i++){ ArrayList<Integer> numbers = new ArrayList<Integer>(); numbers = this.makeNumbers(numbers); // step through each column to find the givens and remove from numbers for (int j = 0; j < size; j++){ if (this.grid[i][j] != 0){ numbers.remove(this.grid[i][j]); } } // go back through the row and assign the numbers randomly for (int j = 0; j < size; j++){ if (this.grid[i][j] == 0){ int r = rand.nextInt(numbers.size()); this.grid[i][j] = numbers.get(r); numbers.remove(r); } } } System.out.println("============="); System.out.println(this.toString()); }

  • Filter to values in collection in one query

    - by dotnetdev
    Hi, I have the following LINQ query: List<string> Types = (List<string>) Directory.GetFiles(@"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727") Where(x => System.IO.Path.GetFileNameWithoutExtension(x).Contains("Microsoft")) .ToList<string>(); How could I modify this so it can only get the values stored in a collection, without writing another LINQ query (which I assume will impact performance?)? Thanks

  • display several items in one row of a listview in android

    - by Sephy
    I don't now if this title is very clear, but I would like to understand how this is possible : And how we can have 2 elements on the same row of the listview, and handle different clicks, as the listview deals with handling the click on a child. Thanks for anyone who could point me in the right direction.

  • Breaking One Big Graphic of MutablePaths into CAShapeLayers

    - by StackOverFlowRider
    I have a class called GraphicView that takes a Graphic object and draws it in its drawRect method. This Graphic object is basically an array of mutablePaths that comprise an icon that I want drawn. For performance and other issues, I was thinking of taking this icon that is comprised of mutablePaths, and dividing it into a bunch of CAShapeLayers. I'm wondering is this possible? Considering the points for the mutablePaths of the icon are all interwoven together (ie the icon was initially an SVG file that I converted to code), is it possible to divide different parts of the icon into CAShapeLayers, and reassemble them all together when assigning to the views layer? If so how would it be done? If I assign them as sublayers to a CALayer or CAShapeLayer, will it understand to mesh them all together?

  • How to save to two tables using one SQLAlchemy model

    - by Oatman
    I have an SQLAlchemy ORM class, linked to MySQL, which works great at saving the data I need down to the underlying table. However, I would like to also save the identical data to a second archive table. Here's some psudocode to try and explain what I mean my_data = Data() #An ORM Class my_data.name = "foo" #This saves just to the 'data' table session.add(my_data) #This will save it to the identical 'backup_data' table my_data_archive = my_data my_data_archive.__tablename__ = 'backup_data' session.add(my_data_archive) #And commits them both session.commit() Just a heads up, I am not interested in mapping a class to a JOIN, as in: http://www.sqlalchemy.org/docs/05/mappers.html#mapping-a-class-against-multiple-tables

  • Prism: How to render one view on top of another

    - by Nate Noonen
    We have a Prism/WPF application and are using an expander to animate a menu. When the expander expands, the content is rendered behind the main region's content. The menu is in a different region than the content it is supposed to overlay (since the menu governs what items go into that region) which is why this is occurring. We have tried setting the Z-Index of the ContentControls to no avail.

  • How can one use multi threading in php applications

    - by Steve Obbayi
    Is there a realistic way of implementing a multi-threaded model in php whether truly or just simulating it. Some time back it was suggested that you can force the operating system to load another instance of the php executable and handle other simultaneous processes. The problem with this is that when the php code finished executing the php instance remains in memory because there is no way to kill it from within php. so if you are simulating several threads you can imagine whats going to happen. So am still looking for a way multi-threading can be done or simulated effectively from within php. Any ideas?

  • SQL Select between two fields depending on the value of one field

    - by Filip
    Hi. I am using a PostgreSQL database, and in a table representing some measurements I've two columns: measurement, and interpolated. In the first I've the observation (measurement), and b is the interpolated value depending on nearby values. Every record with an original value has also an interpolated value. However, there are a lot of records without "original" observations (NULL), hence the values are interpolated and stored in the second column. So basically there are just two cases in the database: Value Value NULL Value Of course, it is preferable to use the value from the first column if available, hence I need to build a query to select the data from the first column, and if not available (NULL), then the database returns the value from the second column for the record in question. I have no idea how to build the SQL query. Please help. Thanks.

  • WPF Custom Navigation Buttons and calling one page from another

    - by Jeff
    I have a window which contains a Frame which references a 'home' page that has buttons on it. When a button is clicked I want another page to show depending on which button was pressed. I attempted to use NavigationService.Navigate('mynextpage.xaml') and that works however, I want to use a customized navigation panel. I call this.ShowsNavigationUI = false; on my 'home' page but the bar still shows. Is there a way to accomplish what I am trying to do? My page with the frame is a window so I do not know how to disable the Navigation bar there where I guess it is coming from. Further testing shows that the ShowsNavigationUI property is false yet the nav bar shows itself in the parent window once there is a second page to go to (showing the 'home' page in the history. TIA

  • Rails: Link changes one attribute and then goes back

    - by James
    Rails newbie here. I have a list of items which can have a status represented by an integer (right now its just 1=active 0=inactive). What I want is next to each item a link to change the status of that item. So it might look like this: A nice item - Enable Another pretty item - Disable I can't think of how to make the link work. I just want a user to click the link and then the page refreshes and the item get updated. This doesn't work: <%= link_to "Enable", :controller => "items", :action => "update", :status => 1 %>

  • Export XML with only one MySQL request ?

    - by mere-teresa
    I want to export in XML format some data from 7 tables (MySQL database), and then I want to import in another database. And I have a update or insert rule for data. I already have a SQL query retrieving all data, with JOINs on my 7 tables. But...when I try to put data in XML format, I reach a limit. My PHP loop can catch each row, but I would like to benefit from hierachical structure of the XML, and all I have are rows with the same data repeated. It is better to query once and to construct the XML tree in PHP or to query each time I want access to a lower level ?

  • One Database Field to Hold Survey Answer

    - by yar
    Skipping the question of whether this is bad design (and the question of why I would want/need to do this), I'm just wondering if my 'math' is right... I have n things that need to be put in order (n is always less than 5): thing1 thing2 thing3 ... and I'd like to store these results in a single integer for thing. My initial thought is that (obviously the code will not look like this): thing = thing1 * 1 + thing2 * 2 + thing3 * 4 + thing5 * 8 will always give me a unique value, and that any value for thing will always translate back to its values for thing1...thingn. Is this correct?

  • Using Java, can I have one JVM spawn another, and then have the original one exit?

    - by CarlG
    I have a need to have a running JVM start another JVM and then exit. I'm currently trying to do this via Runtime.getRuntime().exec(). The other JVM starts, but my original JVM won't exit until the "child" JVM process stops. It appears that using Runtime.getRuntime().exec() creates a parent-child relationship between the processes. Is there some way to de-couple the spawned process so that the parent can die, or some other mechanism to spawn a process without any relationship to the creating process? Note that this seems exactly like this question: http://stackoverflow.com/questions/2566502/using-java-to-spawn-a-process-and-keep-it-running-after-parent-quits but the accepted answer there doesn't actually work, at least not on my system (Windows 7, Java 5 and 6). It seems that maybe this is a platform-dependent behavior. I'm looking for a platform independent way to reliably invoke the other process and let my original process die.

  • C# LINQ join With Just One Row

    - by Soo
    I'm trying to make a query that grabs a single row from an SQL database and updates it. TableA AId AValue TableB BId AId BValue Ok, so TableA and TableB are linked by AId. I want to select a row in TableB based on AValue using a join. The following query is what I have and only grabs a value from TableB based on AId, I just don't know how to grab a row from TableB using AValue. I know you would need to use a join, but I'm not sure how to accomplish that. var row = DbObject.TableB.Single(x => x.AId == 1) row.BValue = 1; DbObject.SubmitChanges();

  • one click, two 'click' event fired

    - by Toni Michel Caubet
    I just want to toggle some elements when a link is clicked: This is how i am trying (But i don't really think that it matters much for this question what's inside the event function callback): /* mostrar exceso de comentarios a peticion del usuario*/ $('.toggleComments').click(function(){ console.log('.toggleComments'); if($(this).parents('.helpContent').find('.commentHideble:visible').length > 0){ $(this).text('+ <?=get_texto_clave('show_old_comments')?>').removeClass('toggleCommentsActive').append(' ('+$(this).parents('.helpContent').find('.commentHideble:not:visible').length+'+)'); }else{ $(this).text('- <?=get_texto_clave('hide_old_comments')?>').addClass('toggleCommentsActive'); } $(this).parents('.helpContent').find('.commentHideble').slideToggle(100); }); I even tried a boolean but gave me same result /* mostrar exceso de comentarios a peticion del usuario*/ var ctoggle = false; $('.toggleComments').click(function(){ if(ctoggle == false){ ctoggle = true; console.log('.toggleComments'); if($(this).parents('.helpContent').find('.commentHideble:visible').length > 0){ $(this).text('+ <?=get_texto_clave('show_old_comments')?>').removeClass('toggleCommentsActive').append(' ('+$(this).parents('.helpContent').find('.commentHideble:not:visible').length+'+)'); }else{ $(this).text('- <?=get_texto_clave('hide_old_comments')?>').addClass('toggleCommentsActive'); } $(this).parents('.helpContent').find('.commentHideble').slideToggle(100); ctoggle = false; } }); Why the log is being fired twice by click?
