• node_load in drupal gets incorrect node when you are NOT logged in

  - by Alaa

  Hi All, i have a module and i am using node_load(array('nid' = arg(1))); now the problem is that this function keep getting its data for node_load from DB cache. how can i force this function to not use DB cache or static value? Example my link is http://mydomain.com/node/344983 now: $node=node_load(array('nid'=arg(1)),null,true); echo $node-nid; output: 435632 which is a randomly node id (available in the database) and everytime i ctrl+F5 my browser, i get new nid!! Note: if i am logged in, it gives the result correctly, but this problem happens only when i am browsing the website as an anonymous user i really appreciate any idea!! Thanks

• Scrapy + Eclipse PyDev : how to setup the debugger?

  - by AsTeR

  I've successfully setup Eclipse with my Scrapy project. I did it by setting a new Run/Debug configuration : Whose main module links to Scrapy /usr/local/bin/scrapy for me (I've found suggestion to use cmdline.py but that failed on my computer (OSX Lion & scrapy installed through easy_install) Defining the arguments to send "crawl ny" in my case as I would if I used the Scrapy command line Setting the correct working directory (${workspace_loc:My Project/src} in my case) Eclipse can successfully launch my project, but I've no debbuger. I'm missing my breakpoints and variable inspection, does anyone know how to setup the debbugger with this environment ?

• Can you make a python script behave differently when imported than when run directly?

  - by futuraprime

  I often have to write data parsing scripts, and I'd like to be able to run them in two different ways: as a module and as a standalone script. So, for example: def parseData(filename): # data parsing code here return data def HypotheticalCommandLineOnlyHappyMagicFunction(): print json.dumps(parseData(sys.argv[1]), indent=4) the idea here being that in another python script I can call import dataparser and have access to dataParser.parseData in my script, or on the command line I can just run python dataparser.py and it would run my HypotheticalCommandLineOnlyHappyMagicFunction and shunt the data as json to stdout. Is there a way to do this in python?

• Extract anything that looks like links from large amount of data in python

  - by Riz

  Hi, I have around 5 GB of html data which I want to process to find links to a set of websites and perform some additional filtering. Right now I use simple regexp for each site and iterate over them, searching for matches. In my case links can be outside of "a" tags and be not well formed in many ways(like "\n" in the middle of link) so I try to grab as much "links" as I can and check them later in other scripts(so no BeatifulSoup\lxml\etc). The problem is that my script is pretty slow, so I am thinking about any ways to speed it up. I am writing a set of test to check different approaches, but hope to get some advices :) Right now I am thinking about getting all links without filtering first(maybe using C module or standalone app, which doesn't use regexp but simple search to get start and end of every link) and then using regexp to match ones I need.

• What is the difference between type.__getattribute__ and object.__getattribute__?

  - by Neil G

  Given: In [37]: class A: ....: f = 1 ....: In [38]: class B(A): ....: pass ....: In [39]: getattr(B, 'f') Out[39]: 1 Okay, that either calls super or crawls the mro? In [40]: getattr(A, 'f') Out[40]: 1 This is expected. In [41]: object.__getattribute__(A, 'f') Out[41]: 1 In [42]: object.__getattribute__(B, 'f') --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) <ipython-input-42-de76df798d1d> in <module>() ----> 1 object.__getattribute__(B, 'f') AttributeError: 'type' object has no attribute 'f' What is getattribute not doing that getattr does? In [43]: type.__getattribute__(B, 'f') Out[43]: 1 What?! type.__getattribute__ calls super but object's version doesn't? In [44]: type.__getattribute__(A, 'f') Out[44]: 1

• Best way to identify and dispose locked thread in java.

  - by Bala R

  I have to call a function 3rd party module on a new thread. From what I've seen, the call either completes quickly if everything went well or it just hangs for ever locking up the thread. What's a good way to start the thread and make the call and wait for a few secs and if the thread is still alive, then assuming it's locked up, kill (or stop or abandon) the thread without using any deprecated methods. I have something like this for now, but I'm not sure if this is the best way to do it and I want to avoid calling Thread.stop() as it's deprecated. Thanks. private void foo() throws Exception { Runnable runnable = new Runnable() { @Override public void run() { // stuff that could potentially lock up the thread. } }; Thread thread; thread = new Thread(runnable); thread.start(); thread.join(3500); if (thread.isAlive()) { thread.stop(); throw new Exception(); } }

• Is MVC now the only way to write PHP?

  - by JasonS

  Hey... its XMAS Eve and something is bugging me... yes, I have work on my mind even when I am on holiday. The vast amount of frameworks available for PHP now use MVC. Even ASP.net has its own MVC module. I can see the attraction of MVC, I really can and I use it frequently. The only downside that I can see is that you have to fire up the whole system to execute a page request. Depending on your task this can be a little wasteful. So the question. In a professional environment is this the only way to use PHP nowadays or are their other design methods which have alternative benefits?

• How to make drupal known submitting custom content

  - by Andrew

  Hi, I know this is not a drupal forum but, as I’m not getting any response there, I decided to give it a shot here. I’m creating a web site that accepts custom content from users. So, for that matter, this site has a form and a custom module. Instead of using admin theme, this form is placed inside custom template which is created to have a uniform look with the rest of the pages. As a result, creating form elements through hook_form is out of question. Here’s where my problems lie. As this form uses custom theme, I’m not sure as to what can I do to make drupal know that user is submitting new content data when the form is submitted? Would I need to use same query string that of content submission page of admin page like - ?q=node/add/page for action attribute of the html form? (OR) the only way is to map the url to my custom function and invoke some sort of hook inside of it? Thanks

• Does the Eclipse IDE support JSF 2.0?

  - by Shane

  I have the WTP 3.1 plugin installed and have also installed the Glassfish v3 plugin. I am able to register my server. When I create a dynamic web project, I can see that the maximum dynamic web module version available is 2.5. I then choose the default configuration for Glassfish v3 but, when I look at it JSF, it is not selected by default. When I select it, the maximum version available is 1.2. I want to use JSF with facelets - does Eclipse support this? I can't seem to find anything helpful on the Eclipse WTP site.

• How to: Inline assembler in C++ (under Visual Studio 2010)

  - by toxic shock

  I'm writing a performance-critical, number-crunching C++ project where 70% of the time is used by the 200 line core module. I'd like to optimize the core using inline assembly, but I'm completely new to this. I do, however, know some x86 assembly languages including the one used by GCC and NASM. All I know: I have to put the assembler instructions in _asm{} where I want them to be. Problem: I have no clue where to start. What is in which register at the moment my inline assembly comes into play?

• 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.

• Automatic open Colorbox modal window

  - by user1631168

  I'm using the Colorbox module in Drupal 7. I'm opening an external website. I can make it work with a link. Click here, then click the "colorbox popup" link at the bottom, middle column. The client would like this to open automatically when the page opens. I've created a block and added the following code (from the colorbox site). <script type="text/javascript"> // Display a welcome message on first visit, and set a cookie that expires in 30 days: if (document.cookie.indexOf('visited=true') === -1) { var expires = new Date(); expires.setDate(expires.getDate()+30); document.cookie = "visited=true; expires="+expires.toUTCString(); jQuery.colorbox({html:"http://join.raretearepublic.com/popup/", width:887, height:638}); } </script> But it does not work. Any help would be greatly appreciated.

• Logging fatal/parse errors in PHP5

  - by PeterBelm

  I'm writing an error logging service that will be integrated into websites running on my server, that will email me error batches, etc. So I've been trying to find out if there's a way to handle fatal and parse errors, however not using the tricks to handle it in PHP code (output buffer, shutdown function). I'm quite happy to write some C code or something to handle it outside of my PHP code. I would also like to issue a redirect if possible (my sites use output buffering so there shouldn't be any headers sent). I'm pretty sure this could be done with a PHP module, but I've never written one and have no idea where to start.

• How would I go about writing a Linux TTY sniffer?

  - by alienate

  For educational purposes (not that anyone should care the motivations behind such an exercise) I'd like to write a program that can read/write to/from alternate tty/pty's. I've read papers (from the 1990's) but can't employ the implementation they use, on modern UNIXes. I was hoping that someone had researched into this in the past, or at least, read documentation pertaining to it, that they could provide. I also wonder if (considering the fact that Linux doesn't have STREAMs) if this exercise must be done via a loadable kernel module? I have many questions and probably a misunderstanding of some of the fundamental ideologies that allow such objectives to be put in place, could someone help? :)

• File listing with ActiveX

  - by Studer

  I need to program a simple Windows Explorer that only lists all files inside a folder recursively. The only solution I found up to now is using an ActiveX controller. So, I installed Visual Studio 2010, but I don't know really how to use it to make an ActiveX. I tried to create a Class Library then add a Explorer module. It compiles, but I don't know what to do now. Is there an easier way to do this or am I missing something ?

• using jquery to parse XML export in drupal

  - by gables20

  I need to use jquery to parse a drupal xml export that was created with views datasource module. The format of the xml export is shown below and on the browser, its access by entering, say for example, http://mydomain/test.xml, where test.xml represents the path of the xml export. <node> <node> <nothing> Lorem ipsum </nothing> </node> <node> The jquery to parse xml is shown below. But, it does nothing, which is kind of the main problem. $(document).ready(function(){ $.ajax({ type: "GET", url: "http://mydomain/test.xml", dataType: "xml", success: function(xml){ $(xml).find('node').each(function(){ var title = $(this).find('nothing').text(); $('#output').append($(this).find('nothing').text()); }); } }); });

• Program crash for array copy with ifort

  - by Stefano Borini

  This program crashes with Illegal instruction: 4 on MacOSX Lion and ifort (IFORT) 12.1.0 20111011 program foo real, pointer :: a(:,:), b(:,:) allocate(a(5400, 5400)) allocate(b(5400, 3600)) a=1.0 b(:, 1:3600) = a(:, 1:3600) print *, a print *, b deallocate(a) deallocate(b) end program The same program works with gfortran. I don't see any problem. Any ideas ? Unrolling the copy and performing the explicit loop over the columns works in both compilers. Note that with allocatable instead of pointer I have no problems. The behavior is the same if the statement is either inside a module or not. I confirm the same behavior on Linux using ifort (IFORT) 12.1.3 20120130.

• Integrate ClickOnce update in a setup

  - by Erick

  As recent decision in my team we decided to deploy a software we develop for some time now in ClickOnce. Previously it was deployed with a merge module in a setup project. We had in mind to actually deploy the ClickOnce setup/updater in the web server setup. The problem here would not exactly to integrate it but to make sure to limit the human work to integrate it. Normally I guess it would be necessary to "add - file" and select the folder containing the setup.exe + publish.htm + application files + .application, but I fear that for each time we publish a new version to the hard drive we have to update the setup project as well. Would someone have some insight to help that ? (especially to not have to add the program_[version] folder inside application files that is created each time a new publish is done).

• Pre-packaged Rails applications

  - by Craig

  Seems like most Rails applications have similar 'base' functionality. As such, it seems that there would be value in having pre-build Rails applications at various functionality points such as: basic User model with authentication using Authlogic #1 + openid integration #2 + authorization using declarative_authorization #3 + Administration module #4 + a Profile model Themes (useful stylesheets and such) Friendship model Geocoding ... In addition to the basic MVC stuff, these applications would include: testing harnesses seed data git support One could choose start from any of these functionality points. Other than the sample application that are available with the various gems/plugins, are there projects such as these? If not, I would certainly be willing to contribute what I have.

• What should I do to practice?

  - by simion

  I start a year long industrial placement in September where i will be coding in Java predominantly. I am going to use the summer to brush up on my Java as in year one of the degree Java was the main language taught for OOP modules. However this year i have had no Java exposure except for an algorithms module, which was one of eight, so as you can see i am probably getting really rusty!. What i wanted to know is, how does the "real world" java programming differ from university coding and what do you suggest i brush up on that would be different to my normal workings. As a start I definitely need to get familiar with a professional IDE like NetBeans, opposed to having used BlueJ throughout but more specifically what coding practices should I get more familiar with. I appreciate they wont expect me to be a qualified full developer and will give me time, but I would like to hit the ground running as it were, with me having full hopes to secure a permanent position after I finish my degree.

• Questions about use lib for perl

  - by Tyug

  I use use lib "./DIR" to grab a library from a folder elsewhere. However, it doesn't seem to work on my server, but it works fine on my local desktop. Any particular reasons? And one more question, does use lib get propagated within several modules? Two situations: Say I make a base class that requires a few libraries, but I know that it needs to be extended and the extended class will need to use another library. Can I put the use lib command in the base class? or will I need to put it in every extending class? Finally, can I just have a use package where package contains a bunch of use lib, will it propagate the use lib statements over to my current module? <-- I don't think so, but asking anyways Thanks in advance!

• Custom control packaging

  - by CSharpened

  Quick question: You are building a setup for your application. The application contains a custom control developed by you, which will be shared across multiple applications. How should you package the custom control? Package the control in a Merge Module (.msm) and add the .msm file to a Windows Installer project. Package the control into a cabinet project (.cab) and add the .cab file to a Windows Installer project. Create a separate directory for the control and then package it in a Windows Installer project along with the rest of the project files. Package the control as a Web setup project and create a link to that project from the Windows Installer project. Any ideas?

• Angular function constructor in Controller

  - by BigHeadCreations

  In normal JS I can do this: function Droppable() { this.relevant = true; this.uuid = generateUUID(); }; var generateUUID = function() { return '12345'; } console.log(new Droppable); // returns Droppable {relevant: true, uuid: "12345"} But in Angular I have this: angular.module('myApp').controller('MyCtrl', ['$scope', function($scope) { function Droppable() { this.relevant = true; this.uuid = generateUUID(); } var generateUUID = function() { return '12345'; } // initalize droppable areas $scope.region1 = [new Droppable]; $scope.region2 = [new Droppable]; $scope.region3 = [new Droppable]; }]); I am trying to make 3 droppable areas all with a UUID. But when I do this I get 'undefined is not a function' referring to the line this.uuid = generateUUID(); in function Droppable() {...} Why is that?

• Drupal Hierarchical Content

  - by Vecta

  I am currently looking at using either the Taxonomy or CCK module on my Drupal site as a means to create a hierarchical system. However, I'm a little confused on which one would best suit my needs, or if there is something else that would work better. Basically, there will be probably 70 or so "mini-sites" on the website I'm working on, each with a landing page and about 5 sub-pages of detailed information. I need a way to mark those sub-pages as being sub-pages of their parent page, as well as create a menu system to navigate between them. What is the best way this could be done? Thanks for your input!
