• add methods in subclasses within the super class constructor

  - by deamon

  I want to add methods (more specifically: method aliases) automatically to Python subclasses. If the subclass defines a method named 'get' I want to add a method alias 'GET' to the dictionary of the subclass. To not repeat myself I'd like to define this modifation routine in the base class. But if I check in the base class init method, there is no such method, since it is defined in the subclass. It will become more clear with some source code: class Base: def __init__(self): if hasattr(self, "get"): setattr(self, "GET", self.get) class Sub(Base): def get(): pass print(dir(Sub)) Output: ['__doc__', '__init__', '__module__', 'get'] It should also contain 'GET'. Is there a way to do it within the base class?

• Perl - How to use a process Handle created in a Module in another Perl Script

  - by Zwik

  Ultimately, what I want to do is to start a process in a module and parse the output in real time in another script. What I want to do : Open a process Handler (IPC) Use this attribute outside of the Module How I'm trying to do it and fail : Open the process handler Save the handler in a module's attribute Use the attribute outside the module. Code example : #module.pm self->{PROCESS_HANDLER}; sub doSomething{ ... open( self->{PROCESS_HANDLER}, "run a .jar 2>&1 |" ); ... } #perlScript.pl my $module = new module(...); ... $module->doSomething(); ... while( $module->{PROCESS_HANDLER} ){ ... }

• Change Cursor for Netbeans on Linux

  - by Daziplqa

  Hi, I am recently have been successfully installed NetBean 6.8 on Ubuntu Box (10.04). But the problem is, NetBeans doesn't use the Gnome mouse Cursor by default. instead, It uses some freak mouse cursor that I hate! So, do you have any idea about how to change the cursor that appears inside netbeans.(I have looked inside tools options but without any output) Also I have did: $ grep -iR cursor * Binary file var/cache/all-resources.dat matches Binary file var/cache/all-layers.dat matches Binary file var/cache/index/s2/javascript/8/1/_0.cfs matches (note, I didn't talked here about how to change the cursor inside some Java program written in NetBeans) Thanks in advance.

• Monodevelop: `Waiting for debugger to connect...`

  - by Nicolas Raoul

  I am trying to debug this Mono desktop software in Monodevelop. I imported the SLN file, ran Build all with success, but when I press the Debug button I get this popup that stays waiting forever saying Waiting for debugger to connect...: The output says: User assembly '/home/nico/src/SparkleShare/SparkleShare/bin/SparkleShare.exe' is missing. Debugger will now debug all code, not just user code. Am I doing something wrong? Monodevelop 2.8.6.3 on Ubuntu 2012.04. Nothing special appears on the console with monodevelop -v -v -v. When I press Run instead of Debug, the app crashes immediately saying The application exited with code: 255, but I need Debug to find where the problem is. Note: It is not the same problem as this question, which is about MonoTouch waiting for a phone simulator... the suggestions over there are about the simulator or updating XCode... no simulator nor XCode here.

• Text encoding in HTML text fields

  - by joe

  I have a site up that has a form on it. The form POSTs to a php script which then inserts the data into my database. The page has a charset=UTF-8 attribute in the <meta> tag, and the database is setup to use UTF-8. However, when I copy and paste characters from MS Word into the field, the output is messed up. For example, the quotes in I am using "Microsoft Word" '''' become I am using “Microsoft Word†???? in the database. Anyone have any idea why this might occur?

• SQL Query - Count column values separately

• Compressing assets post-update with Subversion

  - by Oskar Krawczyk

  I'm trying to find a way to compress specific assets post-update on a Production server. So far, I can't find any way to do this that's even remotely simple. Anyone has any insights/experience in doing this? Basically, what I need to do is run a Java utility to compress CSS and JS files - the problem with JS files is that they may or might not validate (JS errors), if it doesn't validate the Java utility will throw output a message. This makes the whole idea a bit more complicated.

• Why is my masm32 program crashing whenever I try using interrupts?

  - by incrediman

  Here's the code: .386 ;target for maximum compatibility .model small,stdcall ;model .code main: int 20h END main Result: http://img705.imageshack.us/img705/3738/resultom.png "test.exe has stopped working" - always right when it reaches the interrupt. This is the interrupt I'm trying to use. It should simply exit the program. Others I've tried include character input/output, etc.. Nothing works. I'm on windows 7, using masm32 with the WinAsm IDE. There are so many cool things it seems I should be able to do with interrupts... however, it crashes whenever I try to use an interrupt - always the same way. This seems related and possibly useful: http://stackoverflow.com/questions/1414260/dos-interrupt-in-masm-x86-assembly-crashing ...but I haven't really been able to figure anything out from it. Any suggestions?

• Removing last word from FOREACH loop

  - by Stoosh

  I'm building a basic function, which builds out Mysql WHERE clauses based on how many are in the array. $array = array('id' => '3', 'name' => 'roger'); $sql = "SELECT * FROM table WHERE "; foreach ($array as $k => $v) { $sql .= $k . ' = ' . $v . ' AND '; } which will output SELECT * FROM table WHERE id = 3 AND name = roger AND However obviously I don't want that last AND, how do I go about removing it from the string? Thanks

• How to simplify this php switch statement?

  - by janoChen

  I would like to change this: // use appropiate lang.xx.php file according to the value of the $lang switch ($_SESSION['lang']) { case 'en': $lang_file = 'lang.en.php'; break; case 'es': $lang_file = 'lang.es.php'; break; case 'zh-tw': $lang_file = 'lang.zh-tw.php'; break; case 'zh-cn': $lang_file = 'lang.zh-cn.php'; break; default: $lang_file = 'lang.en.php'; } into something like this: //include file for final output include_once 'languages/lang.'.$_SESSION['lang'].'php; So that I can skip the whole switch part. I tried other combinations but they don't seem to work. Any suggestions?

• serializing JSON files with newlines in Python

  - by user248237

  I am using json and jsonpickle sometimes to serialize objects to files, using the following function: def json_serialize(obj, filename, use_jsonpickle=True): f = open(filename, 'w') if use_jsonpickle: import jsonpickle json_obj = jsonpickle.encode(obj) f.write(json_obj) else: simplejson.dump(obj, f) f.close() The problem is that if I serialize a dictionary for example, using "json_serialize(mydict, myfilename)" then the entire serialization gets put on one line. This means that I can't grep the file for entries to be inspected by hand, like I would a CSV file. Is there a way to make it so each element of an object (e.g. each entry in a dict, or each element in a list) is placed on a separate line in the JSON output file? thanks.

• Ruby from the command line - sticking - Windows

  - by tyndall

  I have seen this behavior on Windows with Ruby for a long time. If I install a gem sometimes the command line will just get "lost" and stop printing output until you go back to the command line and hit enter a few times. I notice this in other places too. Like starting up a Ruby on Rails console. Or generating a model with Rails. Have other people seen this? What causes this? The weird thing is this doesn't happen all the time. I have never seen this with PHP, Lua, Perl or Python from the command line. I have seen this on Vista and Windows 7 (32-bit and 64-bit). This happens on multiple machines.

• only update certain model attributes using Backbone.js

  - by Drew Dara-Abrams

  With Backbone, I'm trying to update and save to the server just one attribute: currentUser.save({hide_explorer_tutorial: 'true'}); but I don't want to send all the other attributes. Some of them are actually the output of methods on the server-side and so they are not actually true attributes with setter functions. Currently I'm using unset(attribute_name) to remove all the attributes that I don't want to update on the server. Problem is those attributes are then no longer available for local use. Suggestions on how to only save certain attributes to the server?

• [.NET] How to load multiple mscorlib.dll and call their inner functions seperately?

  - by Sean

  Dears, This is for research purpose. I have .Net framework 2.0 installed, and I want to load mscorlib.dll 1.1 dynamiclly to execute its specific inner function. When I wrote this code in C#: static void Main(string[] args) { Assembly assem = Assembly.LoadFrom("C:\\mscorlib_my_private_1.1.dll"); System.Type type = assem.GetType("System.Console"); Type[] typeArray =new Type[1]; typeArray.SetValue(typeof(string),0); System.Reflection.MethodInfo info = type.GetMethod("WriteLine", typeArray); object[] param = new object[1]; param[0] = assem.FullName; type.InvokeMember("WriteLine", System.Reflection.BindingFlags.InvokeMethod, System.Type.DefaultBinder, "", param); } The output is "mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" Not the expected 1.1 version. After Googling a lot, I know that mscorlib.dll is very special, but is it impossible? Cheers~ Sean

• Makefiles - Compile all .cpp files in src/ to .o's in obj/, then link to binary in /

  - by Austin Hyde

  So, my project directory looks like this: /project Makefile main /src main.cpp foo.cpp foo.h bar.cpp bar.h /obj main.o foo.o bar.o What I would like my makefile to do would be to compile all .cpp files in the /src folder to .o files in the /obj folder, then link all the .o files in /obj into the output binary in the root folder /project. The problem is, I have next to no experience with Makefiles, and am not really sure what to search for to accomplish this. Also, is this a "good" way to do this, or is there a more standard approach to what I'm trying to do?

• mysql first record retrieval

  - by Sammy

  While very easy to do in Perl or PHP, I cannot figure how to use mysql only to extract the first unique occurence of a record. For example, given the following table: Name Date Time Sale John 2010-09-12 10:22:22 500 Bill 2010-08-12 09:22:37 2000 John 2010-09-13 10:22:22 500 Sue 2010-09-01 09:07:21 1000 Bill 2010-07-25 11:23:23 2000 Sue 2010-06-24 13:23:45 1000 I would like to extract the first record for each individual in asc time order. After sorting the table is ascending time order, I need to extract the first unique record by name. So the output would be : Name Date Time Sale John 2010-09-12 10:22:22 500 Bill 2010-07-25 11:23:23 2000 Sue 2010-06-24 13:23:45 1000 Is this doable in an easy fashion with mySQL? Thanks, Sammy

• Exceptions silently caught by Windows, how to handle manually?

  - by Mark Ingram

  We're having problems with Windows silently eating exceptions and allowing the application to continue running, when the exception is thrown inside the message pump. For example, we created a test MFC MDI application, and overrode OnDraw: void CTestView::OnDraw(CDC* /*pDC*/) { *(int*)0 = 0; // Crash CTestDoc* pDoc = GetDocument(); ASSERT_VALID(pDoc); if (!pDoc) return; // TODO: add draw code for native data here } You would expect a nasty error message when running the application, but you actually get nothing at all. The program appears to be running perfectly well, but if you check the output window you will see: First-chance exception at 0x13929384 in Test.exe: 0xC0000005: Access violation writing location 0x00000000. First-chance exception at 0x77c6ee42 in Test.exe: 0xC0150010: The activation context being deactivated is not active for the current thread of execution. I know why I'm receiving the application context exception, but why is it being handled silently? It means our applications could be suffering serious problems when in use, but we'll never know about it, because our users will never report any problems.

• How can I make mock-0.6 return a sequence of values?

  - by Chris R

  I'm using the mock-0.6 library from http://www.voidspace.org.uk/python/mock/mock.html to mock out a framework for testing, and I want to have a mock method return a series of values, each time it's called. Right now, this is what I figured should work: def returnList(items): def sideEffect(*args, **kwargs): for item in items: yield item yield mock.DEFAULT return sideEffect mock = Mock(side_effect=returnList(aListOfValues)) values = mock() log.info("Got %s", values) And the log output is this: subsys: INFO: Got <generator object func at 0x1021db500> So, the side effect is returning the generator, not the next value, which seems wrong. Where am I getting this wrong?
