• [Integrity] of a Http Post Request from Iphone to web server

  - by gotye

  Hey everyone, I am currently building a module that makes possible to comment a news and as you probably understood, I will need to insert this new comment in my web database. I know this stuff can be very fastidous so I would like to know if someone has a method which could assure the integrity of the request by checking some of the usual important stuff liek : trimming the string encoding it ? escaping it ? and so on ... If you have some tips to achieve a good insert, do not hesitate ;) Thank you for your time, Gotye.

• how to Calculate number of address bits needed for memory?

  - by leon

  Hi I am preparing my exam for computer system. I don't quite understand how to calculate the number of address bits needed for the memory. For example, Suppose that a 1G x 32-bit main memory is built using 256M x 4-bit RAM chips and this memory is word-addressable. What is the number of address bits needed for a memory module? What is the number of address bits needed for the full memory? And what about If the memory is byte addressable, what would be the solutions? Many thanks

• Does JavaScript have an equivalent to Perl's DESTROY method?

  - by Eric Strom

  Is there any method that is called or event that is dispatched right before an Element is cleaned up by the JavaScript garbage collector? In Perl I would write: package MyObj; sub new {bless {}} sub DESTROY {print "cleaning up @_\n"} and then later: { my $obj = MyObj->new; # do something with obj } # scope ends, and assuming there are no external references to $obj, # the DESTROY method will be called before the object's memory is freed My target platform is Firefox (and I have no need to support other browsers), so if there is only a Firefox specific way of doing this, that is fine. And a little background: I am writing the Perl module XUL::Gui which serves as a bridge between Perl and Firefox, and I am currently working on plugging a few memory leaks related to DOM Elements sticking around forever, even after they are gone and no more references remain on the Perl side. So I am looking for ways to either figure out when JavaScript Elements will be destroyed, or a way to force JavaScript to cleanup an object.

• What is the recommended way to package perl scripts for CPAN (and CorporatePAN)?

  - by szabgab

  Recently I looked at a module on CPAN that comes with a script to be installed which made me wonder. What is the recommended way to include a script in a package that should end up on the public CPAN and if there is any different recommendation for packages that would be released on an in-house CPAN server? The script starts like this: #!/usr/bin/perl eval 'exec /usr/bin/perl -S $0 ${1+"$@"}' if 0; # not running under some shell Two questions Do I understand correctly the eval part is unnecessary? That will be embedded by the CPAN client during installation and it will be very different when installing on Windows. What is the recommended sh-bang line? Would that be #!/usr/bin/env perl instead of the above?

• How to get function's name from function's pointer in C?

  - by Daniel Silveira

  How to get function's name from function's pointer in C? Edit: The real case is: I'm writing a linux kernel module and I'm calling kernel functions. Some of these functions are pointers and I want to inspect the code of that function in the kernel source. But I don't know which function it is pointing to. I thought it could be done because, when the system fails (kernel panic) it prints out in the screen the current callstack with function's names. But, I guess I was wrong... am I?

• Is it still too early to hop aboard the Python 3 train?

  - by Znarkus

  I'm still a beginner to Python, so I thought I could as well learn the newest iteration of Python. Especially since it is now 3.1 or 3.2 something. But it seems like many mayor modules are still only supported by 2.6. Like the python-mysql module; from what I read on http://mysql-python.blogspot.com/ it seems like 3.x support won't be seen in any near future. Do you use version 3, how do you get around these problems? Should I retreat to 2.6? If not, what should I use to connect to MySQL?

• Best way to implement symfony admin components

  - by Chris T

  I am coding a backend in symfony using the sfThemePlugin (part of sympal). The dashboard should allow for new "admin plugins" to be added fairly easily. What I'd like is to have a config.yml config like this: sf_easy_admin_plugin: enabled_admin_dashboard_plugins: [Twitter, QuickBlogPost, QuickConfig] and when these are set it includes the correct components into the template. I'd like to have each one be in it's own plugin (sfTwitterEasyAdminModule, sfQuickBlogPostEasyAdminModule) or have them all bundled in one (sfEasyAdminModules). Is there anyway to accomplish this? As far I know symfonys include_component() only let's you include components from the current module and not from other plugins. Each "component" or admin plugin should render an icon for the dashboard and a html form that will be hidden until the user clicks the icon.

• How should I get the value contained in a particular field of a Drupal 7 custom node?

  - by Matt V.

  What is the "proper" way to get the value stored in a particular field within a custom Drupal node? I've created a custom module, with a custom node, with a custom URL field. The following works: $result = db_query("SELECT nid FROM {node} WHERE title = :title AND type = :type", array( ':title' => $title, ':type' => 'custom', ))->fetchField(); $node = node_load($result); $url = $node->url['und']['0']['value']; ...but is there a better way, maybe using the new Field API functions?

• How do I use multiple settings file in Django with multiple sites on one server?

  - by William Bing Hua

  I have an ec2 instance running Ubuntu 14.04 and I want to host two sites from it. On my first site I have two settings file, production_settings.py and settings.py (for local development). I import the local settings into the production settings and override any settings with the production settings file. Since my production settings file is not the default settings.py name, I have to create an environment variable DJANGO_SETTINGS_MODULE='site1.production_settings' However because of this whenever I try to start my second site it says No module named site1.production_settings I am assuming that this is due to me setting the environment variable. Another problem is that I won't be able to use different settings file for different sites. How do I start use two different settings file for two different websites?

• Python: How to run unittest.main() for all source files in a subdirectory?

  - by Pete

  I am developing a Python module with several source files, each with its own test class derived from unittest right in the source. Consider the directory structure: dirFoo\ test.py dirBar\ __init__.py Foo.py Bar.py To test either Foo.py or Bar.py, I would add this at the end of the Foo.py and Bar.py source files: if __name__ == "__main__": unittest.main() And run Python on either source, i.e. $ python Foo.py ........... ---------------------------------------------------------------------- Ran 11 tests in 2.314s OK Ideally, I would have "test.py" automagically search dirBar for any unittest derived classes and make one call to "unittest.main()". What's the best way to do this in practice? I tried using Python to call execfile for every *.py file in dirBar, which runs once for the first .py file found & exits the calling test.py, plus then I have to duplicate my code by adding unittest.main() in every source file--which violates DRY principles.

• Defining multiple VBA objects within one function or sub-routine?

  - by Harokitty

  I have the following VBA code: Option Explicit Private a(2) as Double Private b(2) as Double Public Function Hello(X1 As Double, X2 As Double) As Double a(1) = X1 + X2 a(2) = X1/X2 b(1) = X1 b(2) = X2^2 Hello = a(1)+a(2)+b(1)+b(2) End Function Within the function Hello I have defined a(1),a(2),b(1),b(2). However, I want to make some function or sub-routine that accepts X1 and X2 as arguments and spits out the values for a(1),a(2),b(1),b(2). This is because I use the above definitions for a(1),a(2),b(1),b(2) in about 20 functions in my module and would like to avoid having to do the following in each function that I use thesis in: a(1) = X1 + X2 a(2) = X1/X2 b(1) = X1 b(2) = X2^2

• Beginner Design pattern question (Web Services involved)

  - by zombie

  Hi all ! I am a noob to web services world. I need to develop a login validator module and expose it as a service. I want it to be service independent, i.e I should have the option of exposing it as a SOAP service or REST service in the future. What pattern should I follow ? Sorry if I am unclear in my requirements, I can clarify as per need. Thanks !! Edit : I am using Eclipse as an IDE and Jersey libraries. I am not into any framework, simply using the MVC pattern. I find a lot of difference between SOAP ann REST methods, so I want my methods to be implementation independent - i.e I should be easily able to use my method through a SOAP or REST service call as per need. What should I do for maximum flexibility ?

• Getting Result of $q's Resolution or Rejection

• Can I use a local::lib if local::lib isn't installed globally and without eval-ing it in shell?

  - by xenoterracide

  I have a problem, I want to use local::lib; in a script. But because I need to use this script many places, I don't want to try adding the eval to bashrc, every time I install this script to a server. and I can't get local::lib installed globally (in the default @INC) on the servers. Is there any way I can use local::lib from within the script so that it knows where the module local::lib is without the eval that local::lib recommends and without installing it into a directory in the default @INC on the server?

• Extending fluent nhibernate mappings in another assembly

  - by Jarek

  Hi, I'm using NHibernate with my ASP.Net MVC application. I'm writing some extensions (plugins) for my application. And I'm loading those plugin dynamically (from different assemblies). In my base application I have many entities and mappings defined (User, Group, etc...) I need to create new entities in my extensions, so i.e. I'm creating News module, so I need to create News mapping. In database News table has a foreign key to User table. Is there any way I can modify my User mapping, so it will have: HasMany(x => x.Courses) .KeyColumn("GroupId") .Inverse(); Or the only way to do it is to change code in my User class and recompile project ? I'm not NHibernate advanced user, so any help will be appreciated. TIA.

• Python: Importing a variable inside of a infinite loop

  I have two modules, a host and a scanner. Both loop indefinitely to communicate with the serial ports. I want to import the variable "bestchannel" from scanner into host but by importing it, the while loop inside scanner runs first and loops forever. I want each module to run separately but be able to send each other data in real time. Is this possible? (outside of scanning ram) Example Code: http://pastebin.com/pxUBaima I want minchannel from scanner to be accessible to host.

• Realtime processing and callbacks with Python and C++

  - by Doughy

  I need to write code to do some realtime processing that is fairly computationally complex. I would like to create some Python classes to manage all my scripting, and leave the intensive parts of the algorithm coded in C++ so that they can run as fast as possible. I would like to instantiate the objects in Python, and have the C++ algorithms chime back into the script with callbacks in python. Something like: myObject = MyObject() myObject.setCallback(myCallback) myObject.run() def myCallback(val): """Do something with the value passed back to the python script.""" pass Will this be possible? How can I run a callback in python from a loop that is running in a C++ module? Anyone have a link or a tutorial to help me do this correctly?

• Execute PHP after new Order in Magento

  - by Israel Lopez

  Hello There, I'm trying to figure out where I could drop in some PHP code to notify a CRM we are using (Solve360) that a new order has been placed, and that an event should be created (API) to fulfill the order. Order Product Checkout Complete Checkout & Capture CC Side notify CRM Done Not sure where to start, but I have had to make some small tweaks to fix the Quantum Gateway payment processor to work. In that module it appears that the objects for the order (email, amt, details) were available. However it seems it would be quite 'dirty' to insert more PHP code in there. Ideas? PHP 5.2.x & Magento 1.4.x

• Lua - How to use functions from another script

  - by Person

  I'm wondering how to use functions from another script in Lua. For example, say GameObjectUtilities holds functions that many GameObject scripts will use. The Slime (a GameObject) script wants to use a function in GameObjectUtilities. I'm having trouble getting this to work. I've looked here, but I still don't really fully understand. Do I need to create a module or a table to hold the functions in GameObjectUtilities for the functions in it to be used in other scripts? If so, what is the best way to go about this?
