  • I need to run a PHP script via command line but this happens.

    - by user355367
    I need to run a scrip via command line but the files necessary for me to run it require me to be in the directory of the script. But I cannot do it for every command line i need to run. Their are over five thousand. Could someone tell me how to either format the list easily or add something to the format that would make it run. I have something like this.... php /path/to/the/script/01240/script.php php /path/to/the/script/03770/script.php php /path/to/the/script/02110/script.php php /path/to/the/script/02380/script.php php /path/to/the/script/03220/script.php php /path/to/the/script/02340/script.php php /path/to/the/script/03720/script.php php /path/to/the/script/03460/script.php php /path/to/the/script/0180/script.php php /path/to/the/script/02000/script.php php /path/to/the/script/01830/script.php php /path/to/the/script/0980/script.php php /path/to/the/script/0400/script.php php /path/to/the/script/02750/script.php php /path/to/the/script/0760/script.php php /path/to/the/script/02690/script.php ..... and it goes on for 5000 more lines.

  • parameter error in my Facebook app

    - by Robert
    I have written a small app and put it on facebook. I got an application ID and secret. Then I wrote the following script to access my app (just as told on the facebook page). <?php require './src/facebook.php'; $facebook = new Facebook(array( 'appId' => 'xxxx', 'secret' => 'xxxx', 'cookie' => true, // enable optional cookie support )); try { $me = $facebook->api('/me'); } catch (FacebookApiException $e) { error_log($e); } if ($facebook->getSession()) { echo '<a href="' . $facebook->getLogoutUrl() . '">Logout</a>'; } else { echo '<a href="' . $facebook->getLoginUrl() . '">Login</a>'; } ?> Then I started running this script. It prompted me with the login link, then took me to the facebook login page. However, after I enter my facebook login details, I get this error page: Error. API Error Code: 100 API Error Description: Invalid parameter Error Message: next is not owned by the application. Could anyone help me a little bit please, I am really confused here about what's going on.

  • Close application on error

    - by poke
    I’m currently writing an application for the Android platform that requires a mounted SD card (or ExternalStorage). I know that it might not be the best way to require something like that, but the application will work with quite a lot of data, and I don’t even want to think about storing that on the device’s storage. Anyway, to ensure that the application won’t run without the external storage, I do a quick check in the activity’s onCreate method. If the card is not mounted, I want to display an error message and then quit the application. My current approach looks like this: public void onCreate ( Bundle savedInstanceState ) { super.onCreate( savedInstanceState ); setContentView( R.layout.main ); try { // initialize data storage // will raise an exception if it fails, or the SD card is not mounted // ... } catch ( Exception e ) { AlertDialog.Builder builder = new AlertDialog.Builder( this ); builder .setMessage( "There was an error: " + e.getMessage() ) .setCancelable( false ) .setNeutralButton( "Ok.", new DialogInterface.OnClickListener() { public void onClick ( DialogInterface dialog, int which ) { MyApplication.this.finish(); } } ); AlertDialog error = builder.create(); error.show(); return; } // continue ... } When I run the application, and the exception gets raised (I raise it manually to check if everything works), the error message is displayed correctly. However when I press the button, the application closes and I get an Android error, that the application was closed unexpectedly (and I should force exit). I read some topics before on closing an application, and I know that it maybe shouldn’t happen like that. But how should I instead prevent the application from continuing to run? How do you close the application correctly when an error occurs?

  • SQL: script to create country, state tables

    - by pcampbell
    Consider writing an application that requires registration for an entity, and the schema has been defined to require the country, state/prov/county data to be normalized. This is fairly typical stuff here. Naming also is important to reflect. Each country has a different name for this entity: USA = states Australia = states + territories Canada = provinces + territories Mexico = states Brazil = states Sweden = provinces UK = counties, principalities, and perhaps more! Most times when approaching this problem, I have to scratch together a list of good countries, and the states/prov/counties of each. The app may be concerned with a few countries and not others. The process is full of pain. It typically involves one of two approaches: opening up some previous DB and creating a CREATE script based on those tables. Run that script in the context of the new system. creating a DTS package from database1 to database2, with all the DDL and data included in the transfer. My goal now is to script the creation and insert of the countries that I'd be concerned with in the app of the day. When I want to roll out Countries X/Y/Z, I'll open CountryX.sql, and load its states into the ProvState table. Question: do you have a set of scripts in your toolset to create schema and data for countries and state/province/county? If so, would you share your scripts here? (U.K. citizens, please feel free to correct me by way of a comment in the use of counties.)

  • Have an unprivileged non-account user ssh into another box?

    - by Daniel Quinn
    I know how to get a user to ssh into another box with a key: ssh -l targetuser -i path/to/key targethost But what about non-account users like apache? As this user doesn't have a home directory to which it can write a .ssh directory, the whole thing keeps failing with: $ sudo -u apache ssh -o StrictHostKeyChecking=no -l targetuser -i path/to/key targethost Could not create directory '/var/www/.ssh'. Warning: Permanently added '<hostname>' (RSA) to the list of known hosts. Permission denied (publickey). I've tried variations using -o UserKnownHostsFile=/dev/null and setting $HOME to /dev/null and none of these have done the trick. I understand that sudo could probably fix this for me, but I'm trying to avoid having to require a manual server config since this code will be deployed on a number of different environments. Any ideas? Here's a few examples of what I've tried that don't work: $ sudo -u apache export HOME=path/to/apache/writable/dir/ ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=path/to/apache/writable/dir/.ssh/known_hosts -l deploy -i path/to/key targethost $ sudo -u apache ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=path/to/apache/writable/dir/.ssh/known_hosts -l deploy -i path/to/key targethost $ sudo -u apache ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -l deploy -i path/to/key targethost Eventually, I'll be using this solution to run rsync as the apache user.

  • How do I start up an NSRunLoop, and ensure that it has an NSAutoreleasePool that gets emptied?

    - by Nick Forge
    I have a "sync" task that relies on several "sub-tasks", which include asynchronous network operations, but which all require access to a single NSManagedObjectContext. Due to the threading requirements of NSManagedObjectContexts, I need every one of these sub-tasks to execute on the same thread. Due to the amount of processing being done in some of these tasks, I need them to be on a background thread. At the moment, I'm launching a new thread by doing this in my singleton SyncEngine object's -init method: [self performSelectorInBackground:@selector(initializeSyncThread) withObject:nil]; The -initializeSyncThread method looks like this: - (void)initializeSyncThread { self.syncThread = [NSThread currentThread]; self.managedObjectContext = [(MyAppDelegate *)[UIApplication sharedApplication].delegate createManagedObjectContext]; NSRunLoop *runLoop = [NSRunLoop currentRunLoop]; [runLoop run]; } Is this the correct way to start up the NSRunLoop for this thread? Is there a better way to do it? The run loop only needs to handle 'performSelector' sources, and it (and its thread) should be around for the lifetime of the process. When it comes to setting up an NSAutoreleasePool, should I do this by using Run Loop Observers to create the autorelease pool and drain it after every run-through?

  • backbone js or knockout js as a web framework with jquery mobile

    - by Dan
    without trying to cause a mass discussion I would like some advice from the fellow users of stack overflow. I am about to start building a mobile website that gets it data from JSON that comes from a PHP rest api. I have looked into different mobile frameworks and feel that JQM will work best for us as we have the knowledge of jQuery even though a little large. Currently at work however we are using jQuery for all our sites and realise that now we are building a mobile website I need to think about javascript frameworks to move us onto a more MV* approach, which I understand the benefits of and will bring much needed structure to this mobile site and future web applications we may bring. I have made a comparision table where I have managed to bring the selection down to 2 - backbone and knockout. I have been looking around the web and it seems that there is more support for backbone in general and maybe even more support for backbone with JQM. http://jquerymobile.com/test/docs/pages/backbone-require.html One thing I have noticed however is that backbone doesnt support view bindings (declarative approach) whereas knockout does - is this a massive bonus? one of the main reasons for using a mv* for us is to get more structure - so I would like to use the library that will intergrate best with jQuery and especially jQuery mobile. neither of them seem to have that similar syntax... Thanks

  • Temporary non-const istream reference in constructor (C++)

    - by Christopher Bruns
    It seems that a constructor that takes a non-const reference to an istream cannot be constructed with a temporary value in C++. #include <iostream> #include <sstream> using namespace std; class Bar { public: explicit Bar(std::istream& is) {} }; int main() { istringstream stream1("bar1"); Bar bar1(stream1); // OK on all platforms // compile error on linux, Mac gcc; OK on Windows MSVC Bar bar2(istringstream("bar2")); return 0; } This compiles fine with MSVC, but not with gcc. Using gcc I get a compile error: g++ test.cpp -o test test.cpp: In function ‘int main()’: test.cpp:18: error: no matching function for call to ‘Bar::Bar(std::istringstream)’ test.cpp:9: note: candidates are: Bar::Bar(std::istream&) test.cpp:7: note: Bar::Bar(const Bar&) Is there something philosophically wrong with the second way (bar2) of constructing a Bar object? It looks nicer to me, and does not require that stream1 variable that is only needed for a moment.

  • Phonegap bluetooth plugin not working

    - by user2907333
    First time poster here , so I'm sorry if this question is asked incorrect or if there are any issues. I'm working on a phonegap app for which I need to be able to set up a bluetooth connection between a tablet (android in this case) and a Win CE PC. Currently i'm trying to get the bluetooth part to work on the tablet and i'm using the plug in you can find at https://github.com/tanelih/phonegap-bluetooth-plugin And for the momemt I'm just trying to enable and disable the Bluetooth on the device. In my bluetoothpage.js file i'm using the following method window.bluetooth.prototype.enable(bluetoothTestSucces(),bluetoothTestFail()); The bluetoothTestSucces and bluetoothTestFail functions just show an alert, nothing else. And if i understand the working of phonegap plugins correctly this uses the following code in my bluetooth.js file Bluetooth.prototype.enable = function(onSuccess, onError) { exec(onSuccess, onError, "Bluetooth", "enable", []); } which calls private void enable(JSONArray args, CallbackContext callbackCtx) { try { _bluetooth.enable(); callbackCtx.success(); } catch(Exception e) { this.error(callbackCtx, e.getMessage(), BluetoothError.ERR_UNKNOWN); } } in my BluetoothPlugin.java file. And if the java file returns Succes bluetoothTestSucces() is used and if the java file returns an error bluetoothTestFail() is used. But for some reason it runs both and does not turn on bluetooth on my device. I'm almost certain I've forgotten a link to a file or have linked it wrong somewhere. But I've followed the instructions that were included in the plugin. I've included the Bluetooth permission in my AndoridManifest file which is located in the root directory of my app I've included the plugin in my config.xml file which is located in res/xml I've required the plugin after the deviceready event as follows document.addEventListener("deviceready", onDeviceReady, false); function onDeviceReady() { window.bluetooth = cordova.require("cordova/plugin/bluetooth"); } Could anyone tell me how to fix this or what i've done wrong? thanks Martijn PS: I'm sorry for any language errors, English isn't my native language. edit: forgot to include some code

  • Setting attributes of a class during construction from **kwargs

    - by Carson Myers
    Python noob here, Currently I'm working with SQLAlchemy, and I have this: from __init__ import Base from sqlalchemy.schema import Column, ForeignKey from sqlalchemy.types import Integer, String from sqlalchemy.orm import relationship class User(Base): __tablename__ = "users" id = Column(Integer, primary_key=True) username = Column(String, unique=True) email = Column(String) password = Column(String) salt = Column(String) openids = relationship("OpenID", backref="users") User.__table__.create(checkfirst=True) #snip definition of OpenID class def create(**kwargs): user = User() if "username" in kwargs.keys(): user.username = kwargs['username'] if "email" in kwargs.keys(): user.username = kwargs['email'] if "password" in kwargs.keys(): user.password = kwargs['password'] return user This is in /db/users.py, so it would be used like: from db import users new_user = users.create(username="Carson", password="1234") new_user.email = "[email protected]" users.add(new_user) #this function obviously not defined yet but the code in create() is a little stupid, and I'm wondering if there's a better way to do it that doesn't require an if ladder, and that will fail if any keys are added that aren't in the User object already. Like: for attribute in kwargs.keys(): if attribute in User: user.__attribute__[attribute] = kwargs[attribute] else: raise Exception("blah") that way I could put this in its own function (unless one hopefully already exists?) So I wouldn't have to do the if ladder again and again, and so I could change the table structure without modifying this code. Any suggestions?

  • Submit WordPress form programmatically

    - by songdogtech
    How can I let a user access a WordPress protected page with a URL that will submit the password in the form below? I want to be able to let a user get to a password protected WordPress page without needing to type the password, so when they go to the page, the password is submitted by a POST URL on page load. This not intended to be secure in any respect; I'll need to hardcode the password in the URL and the PHP. It's just for simplicity for the user, and once they're in, the cookie will let them in for 10 more days. I will select the particular user with separate PHP function that determines their IP or WordPress login status. I used Wireshark to find the POST string: post_password=mypassword&Submit=Submit but using this URL mydomain.com/wp-pass.php?post_password=mypassword&Submit=Submit gives me a blank page. This is the form: <form action="http://mydomain.com/wp-pass.php" method="post"> Password: <input name="post_password" type="password" size="20" /> <input type="submit" name="Submit" value="Submit" /></form> This is wp-pass.php: <?php require( dirname(__FILE__) . '/wp-load.php'); if ( get_magic_quotes_gpc() ) $_POST['post_password'] = stripslashes($_POST['post_password']); setcookie('wp-postpass_' . COOKIEHASH, $_POST['post_password'], time() + 864000, COOKIEPATH); wp_safe_redirect(wp_get_referer()); ?> What am I doing wrong? Or is there a better way to let a user into a password protected page automatically?

  • Python: Best way to check for Python version in program that uses new language features?

    - by Mark Harrison
    If I have a python script that requires at least a particular version of python, what is the correct way to fail gracefully when an earlier version of python is used to launch the script? How do I get control early enough to issue an error message and exit? For example, I have a program that uses the ternery operator (new in 2.5) and "with" blocks (new in 2.6). I wrote a simple little interpreter-version checker routine which is the first thing the script would call ... except it doesn't get that far. Instead, the script fails during python compilation, before my routines are even called. Thus the user of the script sees some very obscure synax error tracebacks - which pretty much require an expert to deduce that it is simply the case of running the wrong version of python. update I know how to check the version of python. The issue is that some syntax is illegal in older versions of python. Consider this program: import sys if sys.version_info < (2, 4): raise "must use python 2.5 or greater" else: # syntax error in 2.4, ok in 2.5 x = 1 if True else 2 print x When run under 2.4, I want this result $ ~/bin/python2.4 tern.py must use python2.5 or greater and not this result: $ ~/bin/python2.4 tern.py File "tern.py", line 5 x = 1 if True else 2 ^ SyntaxError: invalid syntax (channeling for a coworker)

  • Drawing only part of a texture OpenGL ES iPhone

    - by Ben Reeves
    ..Continued on from my previous question I have a 320*480 RGB565 framebuffer which I wish to draw using OpenGL ES 1.0 on the iPhone. - (void)setupView { glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteriv(GL_TEXTURE_2D, GL_TEXTURE_CROP_RECT_OES, (int[4]){0, 0, 480, 320}); glEnable(GL_TEXTURE_2D); } // Updates the OpenGL view when the timer fires - (void)drawView { // Make sure that you are drawing to the current context [EAGLContext setCurrentContext:context]; //Get the 320*480 buffer const int8_t * frameBuf = [source getNextBuffer]; //Create enough storage for a 512x512 power of 2 texture int8_t lBuf[2*512*512]; memcpy (lBuf, frameBuf, 320*480*2); //Upload the texture glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, 512, 512, 0, GL_RGB, GL_UNSIGNED_SHORT_5_6_5, lBuf); //Draw it glDrawTexiOES(0, 0, 1, 480, 320); [context presentRenderbuffer:GL_RENDERBUFFER_OES]; } If I produce the original texture in 512*512 the output is cropped incorrectly but other than that looks fine. However using the require output size of 320*480 everything is distorted and messed up. I'm pretty sure it's the way I'm copying the framebuffer into the new 512*512 buffer. I have tried this routine int8_t lBuf[512][512][2]; const char * frameDataP = frameData; for (int ii = 0; ii < 480; ++ii) { memcpy(lBuf[ii], frameDataP, 320); frameDataP += 320; } Which is better, but the width appears to be stretched and the height is messed up. Any help appreciated.

  • Accessing previous activity instances in a sequence activity

    - by Dan Revell
    This has a rather SharePoint spin to it but the problem is straight workflow. I've got a parallel replication activity which contains a sequence activity. The sequence activity contains a CreateTask activity, a CodeActivity, a OnTaskChanged activity and finally a CompleteTask activity. The idea is to create a task for each username passed into the ReplicatorActivity.InitialChildData property. Typically in workflow I bind a field to the CreateTask.TaskId and CreateTask.TaskProperties and inside the CreateTask.MethodInvoking I set these through the local bound fields. This works and my tasks all get created properly. However in the CodeActivity that follows, I want to then access the TaskProperties. The problem I am encountering is that this field holds the values of the final task to be created as the CreateTask runs for all the replications before the CodeActivity gets to runs. From the CodeActivity, here are two ways I've tried to access the CreateTask activity instance from the same context or instance or whatever the terminology is for the replicated sequence. CreateTask task = ((CreateTask)sender.Parent.GetActivityByName("createSoftwareRequestTask", true)); CreateTask createTask = (CreateTask)sender.Parent.Activities[0]; Unfortunately the CreateTask activities both refer back to the last task to be created and not the task from the context that the CodeActivity is executing within. Two reasons why this might be that I can think of. I'm not accessing the correct instance with my code. I am accessing the correct instance, but as the properties I require were bound to and set through local fields then their previous data was overwritten. I'm hitting a brick wall with my understanding of workflow with this and would very much appreciate some assistance here.

  • Reference 3.5 assembly from 4.0 winforms phail

    - by Dean Lunz
    So I have this utility library that is compiled as a dll under .net 3.5 and it is used by my asp.net 3.5 website. I created a .net 4.0 winforms app to push data onto the website. I want to make use of the functionality in the utilities library from this winforms app. The problem lies in that when I make reference to the utilities library and use the code in it intellisense barks at me saying that it can't find the objects in that library. The thing is I would switch the winforms app to 3.5 which fixes the problem, but I am using Tasks which require 4.0. And because my website and utilities library both run 3.5 and my website is hosted at godaddy that currently only supports asp.net 3.5 so compiling my utilities library under 4.0 for my winforms app is not going to work because it breaks my website. I have tried the app.config trick ala useLegacyV2RuntimeActivationPolicy="true" ... But that did not help. Obviously I could start a new utilities project for 4.0 and and copy the code files from the existing utilities library then reference the new 4.0 utilities library in my winforms app but, that strikes me as being rather overkill when all I want to do is reference the library and use it's functionality. Not to mention that I would have two utility libraries both containing the exact same code, and if I update the code in one I will need to make sure that the other is also updated. I could use add file as link, but you get the idea. So is there anything else I could try or any other way to solve or get around this? Or am I just going to have to break down and create a identical clone of the utilities library for 4.0.

  • memory alignment within gcc structs

    - by Mumbles
    I am porting an application to an ARM platform in C, the application also runs on an x86 processor, and must be backward compatible. I am now having some issues with variable alignment. I have read the gcc manual for __attribute__((aligned(4),packed)) I interpret what is being said as the start of the struct is aligned to the 4 byte boundry and the inside remains untouched because of the packed statement. originally I had this but occasionally it gets placed unaligned with the 4 byte boundary. typedef struct { unsigned int code; unsigned int length; unsigned int seq; unsigned int request; unsigned char nonce[16]; unsigned short crc; } __attribute__((packed)) CHALLENGE; so I change it to this. typedef struct { unsigned int code; unsigned int length; unsigned int seq; unsigned int request; unsigned char nonce[16]; unsigned short crc; } __attribute__((aligned(4),packed)) CHALLENGE; The understand I stated earlier seems to be incorrect as both the struct is now aligned to a 4 byte boundary, and and the inside data is now aligned to a four byte boundary, but because of the endianess, the size of the struct has increased in size from 42 to 44 bytes. This size is critical as we have other applications that depend on the struct being 42 bytes. Could some describe to me how to perform the operation that I require. Any help is much appreciated.

  • How to exit an if clause

    - by Roman Stolper
    What sorts of methods exist for prematurely exiting an if clause? There are times when I'm writing code and want to put a break statement inside of an if clause, only to remember that those can only be used for loops. Lets take the following code as an example: if some_condition: ... if condition_a: # do something # and then exit the outer if block ... if condition_b: # do something # and then exit the outer if block # more code here I can think of one way to do this: assuming the exit cases happen within nested if statements, wrap the remaining code in a big else block. Example: if some_condition: ... if condition_a: # do something # and then exit the outer if block else: ... if condition_b: # do something # and then exit the outer if block else: # more code here The problem with this is that more exit locations mean more nesting/indented code. Alternatively, I could write my code to have the if clauses be as small as possible and not require any exits. Does anyone know of a good/better way to exit an if clause? If there are any associated else-if and else clauses, I figure that exiting would skip over them.

  • Nested namespaces, correct static library design issues

    - by PeterK
    Hello all, I'm currently in the process of developing a fairly large static library which will be used by some tools when it's finished. Now since this project is somewhat larger than anything i've been involved in so far, I realized its time to think of a good structure for the project. Using namespaces is one of those logical steps. My current approach is to divide the library into parts (which are not standalone, but their purpose calls for such a separation). I have a 'core' part which now just holds some very common typedefs and constants (used by many different parts of the library). Other parts are for example some 'utils' (hash etc.), file i/o and so on. Each of these parts has its own namespace. I have nearly finished the 'utils' part and realized that my approach probably is not the best. The problem (if we want to call it so) is that in the 'utils' namespace i need something from the 'core' namespace which results in including the core header files and many using directives. So i began to think that this probably is not a good thing and should be changed somehow. My first idea is to use nested namespaces as to have something like core::utils. Since this will require some heavy refactoring i want to ask here first. What do you think? How would you handle this? Or more generally: How to correctly design a static library in terms of namespaces and code organization? If there are some guidelines or articles about it, please mentoin them too. Thanks. Note: i'm quite sure that there are more good approaches than just one. Feel free to post your ideas, suggestions etc. Since i'm designing this library i want it to be really good. The goal is to make it as clean and FAST as possible. The only problem is that i will have to integrate a LOT of existing code and refactor it, which will really be a painful process (sigh) - thats why good structure is so important)

  • php user authentication libraries / frameworks ... what are the options?

    - by es11
    I am using PHP and the codeigniter framework for a project I am working on, and require a user login/authentication system. For now I'd rather not use SSL (might be overkill and the fact that I am using shared hosting discourages this). I have considered using openID but decided that since my target audience is generally not technical, it might scare users away (not to mention that it requires mirroring of login information etc.). I know that I could write a hash based authentication (such as sha1) since there is no sensitive data being passed (I'd compare the level of sensitivity to that of stackoverflow). That being said, before making a custom solution, it would be nice to know if there are any good libraries or packages out there that you have used to provide semi-secure authentication? I am new to codeigniter, but something that integrates well with it would be preferable. Any ideas? (i'm open to criticism on my approach and open to suggestions as to why I might be crazy not to just use ssl). Thanks in advance. Update: I've looked into some of the suggestions. I am curious to try out zend-auth since it seems well supported and well built. Does anyone have experience with using zend-auth in codeigniter (is it too bulky?) and do you have a good reference on integrating it with CI? I do not need any complex authentication schemes..just a simple login/logout/password-management authorization system. Also, dx_auth seems interesting as well, however I am worried that it is too buggy. Has anybody else had success with this? I realized that I would also like to manage guest users (i.e. users that do not login/register) in a similar way to stackoverflow..so any suggestions that have this functionality would be great

  • "ImportError: cannot import name Exchange" when using Celery w/ Kombu installed

    - by alukach
    I'm trying to create a Celery worker node on an Amazon EC2 Windows2008 R2 instance. Due to a plugin we require for another Python module, we are required to user Python3. I've installed Python3.2 and necessary modules and run Celery, but for some reason it states that it can't import Exchange and Queue from Kombu, despite the face that Kombu is installed and can be imported by python.

  • Optimizing processing and management of large Java data arrays

    - by mikera
    I'm writing some pretty CPU-intensive, concurrent numerical code that will process large amounts of data stored in Java arrays (e.g. lots of double[100000]s). Some of the algorithms might run millions of times over several days so getting maximum steady-state performance is a high priority. In essence, each algorithm is a Java object that has an method API something like: public double[] runMyAlgorithm(double[] inputData); or alternatively a reference could be passed to the array to store the output data: public runMyAlgorithm(double[] inputData, double[] outputData); Given this requirement, I'm trying to determine the optimal strategy for allocating / managing array space. Frequently the algorithms will need large amounts of temporary storage space. They will also take large arrays as input and create large arrays as output. Among the options I am considering are: Always allocate new arrays as local variables whenever they are needed (e.g. new double[100000]). Probably the simplest approach, but will produce a lot of garbage. Pre-allocate temporary arrays and store them as final fields in the algorithm object - big downside would be that this would mean that only one thread could run the algorithm at any one time. Keep pre-allocated temporary arrays in ThreadLocal storage, so that a thread can use a fixed amount of temporary array space whenever it needs it. ThreadLocal would be required since multiple threads will be running the same algorithm simultaneously. Pass around lots of arrays as parameters (including the temporary arrays for the algorithm to use). Not good since it will make the algorithm API extremely ugly if the caller has to be responsible for providing temporary array space.... Allocate extremely large arrays (e.g. double[10000000]) but also provide the algorithm with offsets into the array so that different threads will use a different area of the array independently. Will obviously require some code to manage the offsets and allocation of the array ranges. Any thoughts on which approach would be best (and why)?

  • How to override the default init.tcl

    - by Sean Murphy
    I'm working on a project where I want to make use of TCL as the command interpreter. I have a working c library object which I can load from within the tcl shell but my problem is finding a way to automatically do this while starting a tclsh. Essentially my ultimate goal is to be able to run a script and have it load my library and run some initial startup tcl code before dropping me back to the tclsh command prompt in interactive mode. e.g. tclsh -f myscript.tcl --then-switch-to-interactive or EXPORT TCLINIT=myscript.tcl tclsh The basic goal is to avoid having to distribute tclsh but rather rely in local user installations of tcl. All I would like to distribute is my library, a startup script and a shell command to launch the tclsh with the library preloaded. I've tried using the environment variables TCLINIT and TCL_LIBRARY but they seem to have no effect. The only workable solutions I've found so far are to add "source myscript.tcl" to either the end of /usr/share/tcltk/tcl8.5.init.tcl or ~/.tclshrc However both of these "solutions" are non perfect as they require modification of the default users workspace. It strikes me that there must be a way to handle this in TCL, but my research so far hasn't yielded anything. Does anyone have any suggestions?

  • Center a TextBox over the top of a ScrollViewer in WPF.

    - by Eric
    I have a MainView that contains a navigation bar which selects one of many XAML pages to be displayed in the page view pane. The MainView contains a ScrollViewer around the pages. This allows the pages to be whatever size they need to be and the MainView's ScrollViewer scrolls them. This all works great. On one of the pages, I need to (sometimes) center a TextBox in the middle of the page view pane (over the top of the page content). This was easily done by placing both the page content and the TextBox overlapping each other in a Grid (and I hide the TextBox as necessary). This all seems to work great. However, if the page content grows to be larger than the pane, the TextBox is centered not on the pane, but on the full page content. Thus, it moves from center screen down and/or to the right (and eventually off the screen). Bummer. Options: Remove the ScrollViewer from the MainView. This would require placing one on every page! Argh. Do option #1, and create a ScrolledPage base class. This is a lot of work, and I'm worried about tools issues (Blend issues). It also requires changing every page (to subclass this page). Somehow override the ScrollViewer on just this page. Then, place another ScrollViewer on the page content to Scroll it. Option 3 seems preferable, because it contains the issue to just modifying this page (instead of changing the rest of the pages). However, I can't figure out how to do it. Ideas? Thanks in advance!

  • haml - if-else with different identations

    - by egarcia
    Hi everyone, I'm trying to render a calendar with rails and haml. The dates used come from a variable called @dates. It is a Date range that contains the first and last days to be presented on the calendar. The first day is always sunday and the last one is always monday. I'm planning to render a typical calendar, with one column per weekday (sunday is going to be the first day of the week) using an html table. So, I need to put a %tr followed by a %td on sundays, but the rest of the days I just need a %td. I'm having trouble modelling that on haml. This seems to require different levels of identation, and that's something it doesn't like. Here's my failed attempt: %table %tr %th= t('date.day_names')[0] # Sunday %th= t('date.day_names')[1] %th= t('date.day_names')[2] %th= t('date.day_names')[3] %th= t('date.day_names')[4] %th= t('date.day_names')[5] %th= t('date.day_names')[6] # Monday [email protected] do |date| - if(date.wday == 0) # if date is sunday %tr %td=date.to_s - else %td=date.to_s This doesn't work the way I want. The %tds for the non-sunday days appear outside of the %tr: <tr> <td>2010-04-24</td> </tr> <td>2010-04-25</td> <td>2010-04-26</td> <td>2010-04-27</td> <td>2010-04-28</td> <td>2010-04-29</td> <td>2010-04-30</td> I tried adding two more spaces to the else but then haml complained about improper identation. What's the best way to do this? Note: I'm not interested on rendering the calendar using unordered lists. Please don't suggest that.
