  • (partial apply str) and apply-str in clojure's ->

    - by Jason Baker
    If I do the following: user=> (-> ["1" "2"] (partial apply str)) #<core$partial__5034$fn__5040 clojure.core$partial__5034$fn__5040@d4dd758> ...I get a partial function back. However, if I bind it to a variable: user=> (def apply-str (partial apply str)) #'user/apply-str user=> (-> ["1" "2" "3"] apply-str) "123" ...the code works as I intended it. I would assume that they are the same thing, but apparently that isn't the case. Can someone explain why this is to me?

  • Finding zoom level from window object properties

    - by Mihai Fonoage
    Hi, I want to find out the zoom level of what is being displayed in a browser window based on the javascripts' window object properties (http://www.javascriptkit.com/jsref/window.shtml) to which I have access. I just can't seem to find the right mathematical formula for the zoom based on the inner width, page offset, etc. I found a solution, but that uses the document.body.getBoundingClientRect call which does not return anything in my case and for which I can't tell if there's a suitable replacement from the window properties. I am using Safari. Thank you, Mihai

  • Shipping Java code with data baked into the .jar

    - by Andrew
    I need to ship some Java code that has an associated set of data. It's a simulator for a device, and I want to be able to include all of the data used for the simulated records in the one .JAR file. In this case, each simulated record contains four fields (calling party, called party, start of call, call duration). What's the best way to do that? I've gone down the path of generating the data as Java statements, but IntelliJ doesn't seem particularly happy dealing with a 100,000 line Java source file! Is there a smarter way to do this? In the C#/.NET world I'd create the data as a separate file, embed it in the assembly as a resource, and then use reflection to pull that out at runtime and access it. I'm unsure of what the appropriate analogy is in the Java world. FWIW, Java 1.6, shipping for Solaris.

  • how to move and print squares visited by a knight in following order?

    - by josh kant
    Lets say you have a 5/5 board and you place and the knight started moving form the middle square. Every time knight moves it has to follow the following pattern. its easy if you draw what i mean. I am trying to code for the possible moves and print out the no. of moves in the nXn (in this case 5X5) board. The print out should be the no. of order in which the knight moved. { //move 1 //2 squares up and 1 to the left //move 2 //2 squares up and 1 to the right //move 3 //1 square up and 2 to the right //move 4 //1 square down and 2 to the right //move 5 //2 squares down and 1 to the right //move 6 //2 squares down and 1 to the left //move 7 //1 square down and 2 to the left //move 8 //one square up and 2 to the left } Any help would be appreciated. Thank you in advance..

  • best way to authenticate and consume web service using phonegap (html5/javascript)

    - by Raiss
    I am going to develop a phonegap application which is pretty simple. I need to implement an authentication and some simple data transfer back and forth to the phone and server. I prefer to use ASP.NET as a web service and our database is MS SQL but I am not sure what approach should I take to create a secure communication between Phonegap App and webservice. The problem with a simple AJAX request is limitation in cross-domain and I’m not sure if JSONP is a good option. I was wondering if someone can tell me what technology I should use in order to make a semi secure connection which works with PhoneGap (html5, javascript ) and .Net webservice. I understand that it’s a general question but I need to know what technology is the best in such a case. thanks

  • How to get the row and column of button clicked, in the grid event handler?

    - by younevertell
    Once the added button in grid is clicked, how to find which row and column the button is located in the grid event handler, like click event or some other events? Not the button click event handler #region Grid event handler setup myGrid.MouseEnter += new MouseEventHandler(myGrid_MouseEnter); myGrid.MouseLeave += new MouseEventHandler(myGrid_MouseLeave); myGrid.MouseDown += new MouseButtonEventHandler(myGrid_MouseDown); myGrid.MouseUp += new MouseButtonEventHandler(myGrid_MouseUp); #endregion Thanks I notice that Boyan has some solution for the button click event handler case http://stackoverflow.com/questions/363100/in-wpf-how-can-i-determine-what-column-row-in-a-grid-a-control-is In the Click event handler for the button you say: int row; Button btn = sender as Button; if (btn != null) { row = Grid.GetRow(btn); // And you have the row number... } else { // A nasty error occurred... }

  • Loading a UIDatePicker in Landscape on a UINavigationController

    - by Ryan
    I have a custom UINavigationController that supports auto-rotate. I also have a UIDatePicker on one of my views that I throw onto the stack of the Navigation controller. The auto-rotate works if I start the date picker view in portrait and then rotate it. If I try load the date picker view in landscape to begin with, the view is all messed up. It looks like it would if it didn't support rotation and the frame only has about half of the picker visible and off center. I've tried making my own date picker that supports auto-rotate in case that was the problem, I've tried creating two different views and swapping them out, and I've tried changing the view frame size on the ViewWillAppear method. None of them seem to be working for me as of yet. Anyone have any suggestions on how to get the date picker to show up in landscape correctly on a navigation controller? I probably am overlooking something simple and the answer is right in front of me, but I'm not finding it.

  • Contracts vs Exceptions

    - by devoured elysium
    Let's assume I have the following code: public class MainClass { public static void main(String[] args) { System.out.println(sumNumbers(10, 10)); } //@requires a >= 10; //@ensures \result < 0; public static int sumNumbers(int a, int b) { return a+b; } } I can make 2 things here: Use Code Contracts (in this case, what is in comments). When sumNumbers is run and a < 10, it will throw immediatly an exception (although it doesn't seem to be very descriptive): Exception in thread "main" org.jmlspecs.jmlrac.runtime.JMLInternalNormalPostconditionError: by method MainClass.sumNumbers at MainClass.sumNumbers(MainClass.java:500) at MainClass.internal$main(MainClass.java:9) at MainClass.main(MainClass.java:286) or... Throw an exception. The exception can be as descriptive as I want. I'd also to check in the end of the function to see whenever the post conditions are true or not. Which would you use here and why?

  • Manage Foreign key and Drop downlist for optional field in .NET

    - by Brij
    What is the best way to handle following situation? A dropdown(for master table) is optional in a particular form. But, In database table the field is constrained with foreign key. If user don't select from dropdown then It creates problem because of foreign key. One solution is to create default option in master table and use it in case of blank selection. but in dropdown, we need to handle this to show on top. Is it perfect solution? Is there any other optimized solution for this? Thanks

  • Lombok with Play 2

    - by Alex Povar
    What about Lombok integration with Play Framework 2? I really like Lombok it make my code more readable and less boilerplate. And Play Framework is wonderful too. But there is a great trouble in case if you going to mixup them. Main reason is that scala temlates in play project compiled before domain classes. So Lombok, which itself is compiler's hack do not generate accessors for that time. The question is: if it any ways to make it work? I found some discussions in Google Groups, but they do not provide any reasonable solution. So have you got any success with it? And.. why guys from Play Framework project do not provide some Lombok-like solution? Anyway Play is full of code-generation magic and shadow compiling... so, why not?

  • How to mock a RIA service

    - by Budda
    Is there any ability to mock methods that are provided with RIA Services? I would like to test my Silverlight App without communication to the server side... I see a following approach: create a separate interface; add it to "base classes" for my RiaService; define each autogenerated RIA-method in this interface; insert dependency so that my "functionality" will depend not from the RiaService, but from the interface that is implemented with RiaService. But for this case I see a problem: how to keep my interface in the auto-generated files? ANy thoughts are welcome.

  • PHP-GD: Dealing with Unicode characters

    - by sehugg
    I am developing a web service that renders characters using the PHP GD extension, using a user-selected TTF font. This works fine in ASCII-land, but there are a few problems: The string to be rendered comes in as UTF-8. I would like to limit the list of user-selectable fonts to be only those which can render the string properly, as some fonts only have glyphs for ASCII characters, ISO 8601, etc. In the case where some decorative characters are included, it would be fine to render the majority of characters in the selected font and render the decorative characters in Arial (or whatever font contains the extended glyphs). It does not seem like PHP-GD has support for querying the font metadata sufficiently to figure out if a character can be rendered in a given font. What is a good way to get font metrics into PHP? Is there a command-line utility that can dump in XML or other parsable format?

  • alternatives to System.Diagnostics.Process.Start when command is too long

    - by Frank Schwieterman
    I have some code which is generating a rather long command that is being sent to System.Diagnostics.Process.Start(). The call fails with a Win32Exception, message "The filename or extension is too long". The path to the program itself is not very long, but the parameters passed in are quite long. I am calling the version where an instance of ProcessStartInfo is passed as the parameter, and in this case its the ProcessStartInfo.Arguments .Field that is very long. (other parameters: CreateNoWindow = true, UseShellExecute = false, RedirectStandardError = true). It looks like the exception is coming from a call to win32 function CreateProcess. Does anyone have an idea of another way to start the process?

  • Lucene.Net PrefixQuery

    - by Sole
    Hi, i´m development a suggest box for my site search service. I has to search fields like these: Visual Basic Enterprise Edition Visual C++ Visual J++ My code is: Directory dir = Lucene.Net.Store.FSDirectory.GetDirectory("Index", false); IndexSearcher searcher = new Lucene.Net.Search.IndexSearcher( dir,true); Term term = new Term("nombreAnalizado", _que); PrefixQuery query = new PrefixQuery(term); TopDocs topDocs = searcher.Search(query, 10000); This code works well in this case: "Enterprise" will match "Visual Basic Enterprise Edition" But "Enterprise E" doesn´t match anything. I removed white spaces at indexing time and when the user is searching. Thanks.

  • Postgresql 8.4 reading OID style BLOBs with Hibernate

    - by peter
    I am getting this weird case when querying Postgres 8.4 for some records with Blobs (of type OIDs) with Hibernate. The query does return all right but when my code wants to read the content of the BLOB with the simple code below, it gets 0 bytes back public static byte[] readBlob(Blob blob) throws Exception { InputStream is = null; try { is = blob.getBinaryStream(); return org.apache.commons.io.IOUtils.toByteArray(is); } finally { if (is != null) try { is.close(); } catch(Exception e) {} } } Funny think is that I am getting this behavior only since I've started adding more then one such records to the table. The underlying JDBC library is type 3 (postgresq 8.4-701). Can someone give me a hint as to how to solve this issue? Thanks Peter

  • TWiki: Restricting users scope of editing the pages.

    - by abhishekgupta92
    I am making a twiki website and I am stuck with a problem. The users have access to write the files. So, I want to include Report Abuse option so that in case of vandalism of someone the thing can be corrected as soon as possible. Also, I am facing one more problem that someone told me that while editing the code the person can change the read/write permissions for the other users. And obviously, that wouldn't be something that I am expecting from Twiki. C'mon there must be some way of moderation in twiki to ensure thatthere is no undesirable content.

  • Use of serialization in JMX calls on Websphere Appserver to avoid ClasscastException

    - by hstoerr
    We are using JMX for communication between different EARs on the same Websphere application server (6.1). All works well if we only use Java types as arguments, but if we use or own the problem is that we get ClassCastExceptions on the receiver side. This is obviously a classloader problem: if the jar with the argument types is put into the JRE endorsed directory, such that all classloaders use exactly the same class, the Exception disappear. But we would much prefer to put the library that defines the argument types in the EAR itself. Now my question: is there a trick to persuade WAS to serialize and deserialize the arguments during the JMX call? I guess in this case the ClassCastException would dissappear.

  • convert string to float without silent NaN/Inf conversion

    - by Peter Hansen
    I'd like convert strings to floats using Python 2.6 and later, but without silently converting things like 'NaN' and 'Inf'. Before 2.6, float("NaN") would raise a ValueError. Now it returns a float for which math.isnan() returns True, which is not useful behaviour for my application. Here's what I've got at the moment: import math def get_floats(source): for text in source.split(): try: val = float(text) if math.isnan(val) or math.isinf(val): raise ValueError yield val except ValueError: pass This is a generator, which I can supply with strings containing whitespace-separated sequences representing real numbers. I'd like it to yield only those fields which are purely numeric representations of floats, as in "1.23" or "-34e6", but not for example "NaN" or "-Inf". Test case: assert list(get_floats('1.23 -34e6 NaN -Inf')) == [1.23, -34000000.0] Please suggest alternatives you consider more elegant, even if they involve "look before you leap" (which is normally considered a lesser approach in Python).

  • Erlang Supervisor Strategy For Restarting Connections to Downed Hosts

    - by derdewey
    I'm using erlang as a bridge between services and I was wondering what advice people had for handling downed connections? I'm taking input from local files and piping them out to AMQP and it's conceivable that the AMQP broker could go down. For that case I would want to keep retrying to connect to the AMQP server but I don't want to peg the CPU with those connections attempts. My inclination is to put a sleep into the reboot of the AMQP code. Wouldn't that 'hack' essentially circumvent the purpose of failing quickly and letting erlang handle it? More generally, should the erlang supervisor behavior be used for handling downed connections?

  • SSD and programming

    - by Simon Johnson
    I'm trying to put together a business case for getting every developer in our company an Intel SSD drive. The main codebase contains roughly 400,000 lines of code. My theory is that since the code is scattered about in maybe 1500 files, an SSD drive would be substantially faster for compiles. The logic being that many small reads really punishes the seak-time bottle-neck of a traditional hard-drive. Am I right? Is SSD worth the money in productivity gains by reducing the edit/compile cycle time?

  • Convert Option[Object] to Option[Int] Implicitly

    - by wheaties
    I'm working with legacy Java code which returns java.lang.object. I'm passing it into a function and I'd like to do some implicit conversions as such: implicit def asInt( _in:Option[Object] ) = _in asInstanceOf[ Option[Int] ] implicit def asDouble( _in:Option[Object] = _in asInstanceOf[ Option[Double] ] private def parseEntry( _name:String, _items:Map[String,Object] ) = _name match{ case docName.m_Constants => new Constants( _items get( Constants m_Epsilon ), _items get( Constant m_Rho ), _items get( Constants m_N ) ) Technically it goes on but I keep getting the same errors: expected Int, Option[Object] found. How have I done my implicits wrong? I was hoping it would do the transformation for me instead of me having to write "asInstanceOf" each and every time.

  • R and SPSS difference

    - by sfactor
    i will be analysing vast amount of network traffic related data shortly. i will pre-process the data in order to analyse it. i have found that R and SPSS are among the most popular tools for statistical analysis. i will also be generating quite a lot of graphs and charts. so i was wondering what is the basic difference between these two softwares. i am not asking which one is better. i just wanted to know what are the difference in terms of workflow between the two besides the fact that SPSS has a GUI. I will be mostly working with scripts in either case anyway so i wanted to know about the other differences.

  • What is the most Word-like ASP.NET custom control that you can buy?

    - by rtemp
    We are looking to implement a rich-text box in an ASP.NET application and our requirements are specific to using the "Track Changes" features of Microsoft Word. The closest thing we found in the RadEditor by Telerik. This is a nice control that has a "Track Changes" button and will give you the ability to track the changes from the text in the box to now. It does not let you track your changes from the two previous versions. We have used CVSWeb in the past and the display was not great but it did have the ability (in a web page) to diff two different versions of text (source code in this case). Does anyone have any experience or know of any web-based diff tools that work nicely with a rich-text editor in the web?
