• Can you return an assignable lvalue in Scala?

  - by Alex R

  (note, lvalue is actually a term from the C grammar, I don't know what it's called in Scala!) Trying to learn Scala... this evening I'm working on an internal DSL for a dynamically scoped language that might resemble PHP syntax. My REPL is: Welcome to Scala version 2.7.6.final (Java HotSpot(TM) Client VM, Java 1.6.0). I have some made-up example code: class $(any: Any) { def update(sym: Symbol, any: Any) { println("line 2 executed");} def -(sym: Symbol) : $ = { println("line 1 executed"); return this } def update(any: Any) { println("line 3 executed");} } The following works as expected: scala var a = new $(0) a: $ = $@19238ad scala a('x) = "blah" line 2 executed On the other hand, why does the following not invoke the 1-parameter update method? scala a = 1 :6: error: type mismatch; found : Int(1) required: $ a = 1 ^ Ultimately, I would like this to work: a-'x = "blah" Thanks

• Calling another a4j:jsFunction in an a4j:jsFunction oncomplete event

  - by user339637

  Hi all , I define some java script function which will call the back-end functions using a4j:jsFunction.For example : <a4j:jsFunction name="function1" action="#{Bean1.action1}" oncomplete="function2();"/> <a4j:jsFunction name="function2" action="#{Bean1.action2}" oncomplete="SomeJSFunc2();"/> Then in the a4j:commandButton , I set the onclick property to call my defined function like it: <a4j:commandButton onclick="function1" oncomplete="SomeJSFunc3();"> When the a4j:commandButton is clicked , #{Bean1.action1} is run .After the #{Bean1.action1} returned , the oncomplete event of the (a4j:jsFunction name="function1") cannot invoke the "#{Bean1.action2}" .How can I solve this problem?

• Microsoft Surface - Flip & Scatter View Items

  - by Angelus

  Hi Guys, I'm currently trying to get flip to work with scatterview items, and I'm having some trouble conceptually with it, using a plugin called Thriple (http://thriple.codeplex.com/). Essentially, a 2 sided thriple control looks like this: <thriple:ContentControl3D xmlns:thriple="http://thriple.codeplex.com/" Background="LightBlue" BorderBrush="Black" BorderThickness="2" MaxWidth="200" MaxHeight="200" > <thriple:ContentControl3D.Content> <Button Content="Front Side" Command="thriple:ContentControl3D.RotateCommand" Width="100" Height="100" /> </thriple:ContentControl3D.Content> <thriple:ContentControl3D.BackContent> <Button Content="Back Side" Command="thriple:ContentControl3D.RotateCommand" Width="100" Height="100" /> </thriple:ContentControl3D.BackContent> </thriple:ContentControl3D> What I'm struggling to grasp is if I should be making 2 separate ScatterView templates to bind to the data I want, and then each one would be the "front" and "back" of a scatterview item OR should i make 2 separate ScatterView items which are bound to the data I want, which is then bound to the "back" and "front" of a main ScatterView item? If there is a better way of using doing flip animations with ScatterViewItem's, that'd be cool too! Thanks!

• BCP task hangs while executing

  - by user350374

  Hey guys, We have a HPC node that runs some of our tasks in it. I have a task in my .net project that kicks the bcp utility on the HPC node and the output of the query that I have runs into 9 Mb. When the HPC node runs this task the output of the query is dumped into a file and then after it dumps around 5mb of data it suddenly stops dumping any more data and this happens all the time. (Please note this isnt any data issue as its not crashing on a particular row every time). this may or may not be of significance but I dump the data into a different server which has adequate permissions set. I have run the command with the same query directly on the hpc node and on other comps and it gives the right output. I'm running the bcp command as follows: var processInfo = new ProcessStartInfo("bcp.exe", argument) { RedirectStandardOutput = true, RedirectStandardError = true, CreateNoWindow = true, UseShellExecute = false }; var proc = new Process { StartInfo = processInfo, EnableRaisingEvents = true }; proc.Exited += new EventHandler(bcp_log); proc.Start(); proc.WaitForExit(); So my code actually waits for each bcp task to run before it goes ahead as I call it multiple times. FYI to remind you again it only fails when my o/p exceeds a certain no of bytes in this case approx 5mb. Any help is much appreciated.

• M2Crypto doesn't install in venv, or swig doesn't define __x86_64__ which breaks compiling against OpenSSL

• Why can't I source my vimrc after installing vundle?

  I'm trying to get my Vim to update on the fly after editing vimrc. So I followed the instructions at Vimcast which basically source vimrc every time you hit save.

• Iphone: UIWebview and double taps

  - by Eyal

  I would like to trap a double tap event in a UIWebView. I have derived a class from UIWebController. When I double tap it seams that the UIWebController itself is responding to my double taps instead of my class. The weird thing is that when I change the inheritance to inherit from UIView everything works just fine. Below are snippets from my code which is supposed to invoke a pop-up when double tapped. In the init function: //Setup action for double tap UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleTap:)]; tap.numberOfTapsRequired = 2; [super addGestureRecognizer:tap]; [tap release]; And Also: - (void)handleDoubleTap:(UIGestureRecognizer *)gestureRecognizer { UIAlertView *someError = [[UIAlertView alloc] initWithTitle: @"Network error" message: @"Hello" delegate: self cancelButtonTitle: @"Ok" otherButtonTitles: nil]; [someError show]; [someError release]; //[[NSNotificationCenter defaultCenter] postNotificationName:NOTIFICATION_FLIP_TO_PAGE_VIEW object:nil]; }

• how to escape white space in bash loop list

  - by MCS

  I have a bash shell script that loops through all child directories (but not files) of a certain directory. The problem is that some of the directory names contain spaces. Here are the contents of my test directory: $ls -F test Baltimore/ Cherry Hill/ Edison/ New York City/ Philadelphia/ cities.txt And the code that loops through the directories: for f in `find test/* -type d`; do echo $f done Here's the output: test/Baltimore test/Cherry Hill test/Edison test/New York City test/Philadelphia Cherry Hill and New York City are treated as 2 or 3 separate entries. I tried quoting the filenames, like so: for f in `find test/* -type d | sed -e 's/^/\"/' | sed -e 's/$/\"/'`; do echo $f done but to no avail. There's got to be a simple way to do this. Any ideas? The answers below are great. But to make this more complicated - I don't always want to use the directories listed in my test directory. Sometimes I want to pass in the directory names as command-line parameters instead. I took Charles' suggestion of setting the IFS and came up with the following: dirlist="${@}" ( [[ -z "$dirlist" ]] && dirlist=`find test -mindepth 1 -type d` && IFS=$'\n' for d in $dirlist; do echo $d done ) and this works just fine unless there are spaces in the command line arguments (even if those arguments are quoted). For example, calling the script like this: test.sh "Cherry Hill" "New York City" produces the following output: Cherry Hill New York City Again, I know there must be a way to do this - I just don't know what it is...

• JSP Custom Taglib: Nested Evaluation

  Say I have my custom taglib: <%@ taglib uri="http://foo.bar/mytaglib" prefix="mytaglib"%> <%@ taglib uri="http://java.sun.com/jstl/core" prefix="c"%> <mytaglib:doSomething> Test </mytaglib:doSomething> Inside the taglib class I need to process a template and tell the JSP to re-evaluate its output, so for example if I have this: public class MyTaglib extends SimpleTagSupport { @Override public void doTag() throws JspException, IOException { getJspContext().getOut().println("<c:out value=\"My enclosed tag\"/>"); getJspBody().invoke(null); } } The output I have is: <c:out value="My enclosed tag"/> Test When I actually need to output this: My enclosed tag Test Is this feasible? How? Thanks.

• conditionals for C++ using MSBuild/vsbuild?

  - by redtuna

  I have a C++ project in Visual Studio 2008 and I'd like to be able to compile several versions from the command line, defining conditional variables (aka #define). If it were just a single file to compile I'd use something like cl /D, but this is complex enough that I would like to be able to use VS's other features like the build order etc. I've seen a similar question asked in stackoverflow and the answer was to use /p:DefineConstants="var1;var2". This doesn't seem to work with C++ though. The other problem with that answer is that it replaces the conditional variables, instead of adding to them. The vcproj files for C++ look quite different. If msbuild (or vsbuild) had a way to change Configurations/Tool[name="VCCLCompilerTool"] we'd be golden. But I haven't found such an option. The vcproj files are under source control so I'd rather not have a script mess with them. I've considered doubling the number of configurations (one with the #define, one without). That'd be annoying, and I'm especially unhappy with having to modify these configurations in tandem every time I need to modify anything there. A previous similar question found no solution. I'm hoping that has changed since? How would you go about building those variants (with and without define) from the command line? Thanks!

• Request for the permission of type 'System.Web.AspNetHostingPermission' failed when compiling web si

  - by ahsteele

  I have been using Windows 7 for a while but have not had to work with a particular legacy intranet application since my upgrade. Unfortunately, this application is setup as an ASP.NET Website project hosted on a remote server. When I have the website open in Visual Studio 2008 and try to debug it I get the following compiler error: Request for the permission of type 'System.Web.AspNetHostingPermission' failed To resolve this issue on Windows Vista machines, I would change the machine's .NET Security Configuration trust level to full for the local intranet (fix outlined here). I believe this configuration utility relied upon the mscorcfg.msc which from some cursory research appears to be apart of the .NET 2.0 SDK. I have tried to follow the instructions from this Microsoft Support article running the command below to no avail.

• Java 1.4 to Java 6 migration

  - by joesatch

  Hi, I have some enterprise apps running on Java 1.4. They mostly invoke Stored Proces on DB, Parse XML files (Not too large files, at the most few megs), read/write from/to disk. We have a requirement where now we have to migrate these apps to Java 6(No code changes to be done at all). My questions: If I dont recompile my apps under Java 6 and just run them with it, will it work fine (I know they 'should'). But if somebody thinks other way round, could you kindly share your thoughts please? More important question is - Will it have any perfomance impact?. As in, App compiled on 1.4 and running on 1.6 vs App compiled and running on 1.6. Is 1.6 gonna do any bytecode optimization for the same old peace of code compared to 1.4? Many Thanks js

• Call stored procedure using Spring SimpleJdbcCall with callback

  - by MFIhsan

  I have an Oracle Stored procedure that takes CLOB input and REFCURSOR output. I invoke the SP via Spring SimpleJdbcCall passing in a RowMapper to map the results. However, since the result set is large, I need to provide callback feature to the client. I can't quite figure out how to add callback for an SP call using Spring - both with and without SimpleJdbcCall. One thought I have is to pass-in a RowCallbackHandler. Will this work or is there a better way to solve this problem? Any help here is appreciated. private Map<String, Object> arguments = ...; SimpleJdbcCall jdbcCall = new SimpleJdbcCall(this.jdbcTemplate) .withCatalogName(this.packageName) .withProcedureName(this.storedProcName) .withoutProcedureColumnMetaDataAccess() .declareParameters(this.outputParameters.toArray(new SqlOutParameter[]{})); if(!isEmpty(inputParameters)) { jdbcCall.declareParameters(inputParameters.toArray(new SqlParameter[]{})); } this.outputParameters.add(new SqlOutParameter(outputParamName, VARCHAR, rowMapper)); jdbcCall.execute(arguments);

• Generating new sources via Maven plugin after compile phase

  - by japher

  I have a Maven project within which I need execute two code generation steps. One generates some Java types, then the second depends on those Java types to generate some more code. Is there a way to have both of these steps happening during my build? At the moment my steps are: execute first code generation plugin (during generate-sources) add directory of generated types to build path execute second code generation plugin (during compile) However my problem is that anything generated by the second code generation plugin will not be compiled (because the compile phase has finished). If I attach the second code generation plugin to an earlier phase, it fails because it needs the classes from the first code generation plugin to be present on the classpath. I know I could split this into two modules with one dependent on the other, but I was wondering if this could be achieved in one pom. It seems like a need a way to invoke compile again after the normal compile phase is complete. Any ideas?

• How to write a C program using the fork() system call that generates the Fibonacci sequence in the

  - by Ellen

  The problem I am having is that when say for instance the user enters 7, then the display shows: 0 11 2 3 5 8 13 21 child ends. I cannot seem to figure out how to fix the 11 and why is it displaying that many numbers in the sequence! Can anyone help? The number of the sequence will be provided in the command line. For example, if 5 is provided, the first five numbers in the Fibonacci sequence will be output by the child process. Because the parent and child processes have their own copies of the data, it will be necessary for the child to output the sequence. Have the parent invoke the wait() call to wait for the child process to complete before exiting the program. Perform necessary error checking to ensure that a non-negative number is passed on the command line. #include <stdio.h> #include <sys/types.h> #include <unistd.h> int main() { int a=0, b=1, n=a+b,i,ii; pid_t pid; printf("Enter the number of a Fibonacci Sequence:\n"); scanf("%d", &ii); if (ii < 0) printf("Please enter a non-negative integer!\n"); else { pid = fork(); if (pid == 0) { printf("Child is producing the Fibonacci Sequence...\n"); printf("%d %d",a,b); for (i=0;i<ii;i++) { n=a+b; printf("%d ", n); a=b; b=n; } printf("Child ends\n"); } else { printf("Parent is waiting for child to complete...\n"); wait(NULL); printf("Parent ends\n"); } } return 0; }

• SQlite: Column format for unix timestamp; Integer types

  - by SF.

  Original problem: What is the right column format for a unix timestamp? The net is full of confusion: some posts claim SQLite has no unsigned types - either whatsoever, or with exception of the 64bit int type (but there are (counter-)examples that invoke UNSIGNED INTEGER). The data types page mentions it only in a bigint example. It also claims there is a 6-byte integer but doesn't give a name for it. Of course standard INTEGER being 4-byte signed signed stores unix timestamps as negative numbers. I've heard that some systems return 64-bit timestamps too. OTOH I'm not too fond of wasting 4 bytes to store 1 extra bit (top bit of timestamp), and even if I have to pick a bigger data format, I'd rather go for the 6-byte one. I've even seen a post that claims SQLite unix timestamp is of type REAL... Complete problem: Could someone please clarify that mess?

• Problems installing PHP's PECL sphinx module

  - by Camsoft

  I've installed the sphinx binaries and libraries and am now trying to install the PECL sphinx module. My system is running OS X 10.6 with MAMP 1.8.2 installed. I try to install sphinx using the following command: sudo pecl install sphinx The PECL command outputs the following: running: phpize Configuring for: PHP Api Version: 20090626 Zend Module Api No: 20090626 Zend Extension Api No: 220090626 The versions above don't match the versions listed when doing a phpinfo(). It seems that PECL is trying to complie against the built-in version of PHP. If I ignore the errors and continue the it will successfully compile and place the sphinx.so file in: /usr/lib/php/extensions/no-debug-non-zts-20090626/sphinx.so when in fact it should be: /Applications/MAMP/bin/php5/lib/php/extensions/no-debug-non-zts-20060613/ I've tried copying the sphinx.so file to the MAMP extensions dir but when I restart apache PHP displays the following warning: PHP Startup: Unable to load dynamic library '/Applications/MAMP/bin/php5/lib/php/extensions/no-debug-non-zts-20060613/sphinx.so I think this is because MAMP is 32bit and the built-in PHP is 64bit so PECL complies for 64bit. I might be completely wrong but I did read this when I goggled on the topic. Does anyone know how to get PECL to map to the MAMP version of PHP instead of the built-in version?

• Why callback functions needs to be static when declared in class

  - by Dave17

  I was trying to declare a callback function in class and then somewhere i read the function needs to be static but It didn't explain why? #include <iostream> using std::cout; using std::endl; class Test { public: Test() {} void my_func(void (*f)()) { cout << "In My Function" << endl; f(); //Invoke callback function } static void callback_func() {cout << "In Callback function" << endl;} }; int main() { Test Obj; Obj.my_func(t.callback_func); }

• Can YAML have inheritance?

  - by Jason

  This question involves a lot of symfony but it should be easy enough for someone to follow who only knows YAML and not symfony. My symfony models come from a three-step process: First, I create the tables in MySQL. Second, I run a symfony command (symfony doctrine:build-schema) to convert my table structure into a YAML file. Third, I run another symfony command (symfony doctrine:build-model) to convert the YAML file into PHP code. Here's the problem: there are some tables in the database that I don't want to end up in my symfony code. For example, let's say I have two tables: one called my_table and another called wordpress. The YAML file I end up with might look like this: MyTable: connection: doctrine tableName: my_table Wordpress: connection: doctrine tableName: wordpress That's great except the wordpress table has nothing to do with my symfony models. The result is that every single time I make a change to my database and generate this YAML file, I have to manually remove wordpress. It's annoying! I'd like to be able to create a file called baseConfig.php or something that looks like this: $config = array( 'MyTable' => array( 'connection' => 'doctrine', 'tableName' => 'my_table', ), 'Wordpress' => array( 'connection' => 'doctrine', 'tableName' => 'wordpress', ), ); And then I could have a separate file called config.php or something where I could make modifications to the base config: unset($config['Wordpress']); So my question is: is there any way to convert YAML into executable PHP code (as opposed to load YAML INTO PHP code like what sfYaml::load() does) to achieve this sort of thing? Or is there maybe some other way to achieve YAML inheritance? Thanks, Jason
