• Python profiler and CPU seconds

  - by dude

  Hey, I'm totally behind this topic. Yesterday I was doing profiling using Python profiler module for some script I'm working on, and the unit for time spent was a 'CPU second'. Can anyone remind me with the definition of it? For example for some profiling I got: 200.750 CPU seconds. What does that supposed to mean? At other case and for time consuming process I got: -347.977 CPU seconds, a negative number! Is there anyway I can convert that time, to calendar time? Cheers,

• javascript : make a new safe class constructor

  - by guilin ??

  sometimes we loss the new keyword when define new object, obj = new Clazz(); //correct obj = Clazz(); //wrong, but no syntax error, hard to debug. I want to write a function to help me create Class and make it new safe. var Class = function(constructor){ //when constructor // if not call by new return new constructor(); // else constructor(); } var MyClazz = Class(function(name){ this.name = name }, SuperClazz1, SuperClass2 ) MyClazz.extend({ show: function(){console.log(this.name)} }) obj1 = new MyClazz(); obj2 = MyClazz(); // obj1 should same as obj2 Is it possible, any exists module?

• How could I insert a string into the response stream anywhere I want?

  - by DM

  There may be an easy way to do this but I can't see it... I created a simple Http Module that starts a timer on the PreRequestHandler and stops the timer on the PostRequestHandler to calculate the time it took the page to load. I then create some simple html and write my results to Response.Write. Since I'm doing this in the PostRequestHandler it's adding my results after the </html> tag. That's fine for testing but I need in a scenario where the page needs to validate. I can't seem to figure out how I could manipulate the Response object to insert my results before the </body> tag. Response.Write and Response.Output.Write don't have that flexibility and I couldn't see a way to work with the Response as a string. Am I missing something easy?

• Where should I declare a list of 5,000+ words?

  - by user647362

  I am writing a game in python in which I must periodically pull a random word from a list of words. When I prototyped my game I declared a word_list = ['cat','dog','rat','house'] of ten words at the top of one of my modules. I then use choice(word_list) to get a random word. However, I must must change this temporary hack into something more elegant because I need to increase the size of the word list to 5,000+ words. If I do this in my current module it will look ridiculous. Should I put all of these words in a flat txt file, and then read from that file as I need words? If so, how would I best do that? Put each word an a separate line and then read one random line? I'm not sure what the most efficient way is.

• Unable to call views

  - by Scott

  I'm using Sails and I when I attempt to call the login action of my UsersController. I know my routing is working, because the console.log successfully logs both the loginpassword and loginname. However, the res.view() doesn't work. Neither does returning res.view(). module.exports = { create: function(req, res) { }, destroy: function(req, res) { }, login: function(req, res) { var loginname = req.param("loginname"); var loginpassword = req.param("loginpassword"); console.log(loginname + ' ' + loginpassword); res.view(); }, logout: function(req, res) { }, _config: {} }; I have a /views/user/login.ejs and all it currently contains is a header block with some test text, but I can't get that to render at all. Any thoughts?

• Run command with no terminal output

  - by Insomaniacal

  Hello, I've searched around online, but can't find the answer to my question. What I want to do is run a command in pythong, using the subprocess module, and store the output in a variable. However, I do not want the command's output to be printed to the terminal. For this code: def storels(): a = subprocess.Popen("ls",shell=True) storels() I get the directory listing in the terminal, instead of having it stored in a. I've also tried def storels(): subprocess.Popen("ls > tmp",shell=True) a = open("./tmp") [Rest of Code] storels() This also prints the output of ls to my terminal. I've even tried this command with the somewhat dated os.system method, since running "ls tmp" in the terminal doesn't print ls to the terminal at all, but stores it in tmp. However, the same thing happens. I'm using python 2.6. Any suggestions? Thanks in advance!

  - by oalo

  I am using Views to display a gallery. Right now I have set up the View so it onlys shows 50 elements, but I want it to display a "Next" button that takes you to the next batch of elements. Preferably using AJAX / without reloading, but its not necessary. How can I do this? I have looked at all the options and searched for a module that does that with no success, but I am sure its a standard funcionality and you people can help me. Thank you for reading.

• Access to related Objects inside a model propery

  - by aliem

  Hi, I just run into some problems with django models. Example code is better than any word: class Cart(models.Model): updated_at = models.DateTimeField(auto_now=True) created_at = models.DateTimeField(auto_now_add=True) def __unicode__(self): return u'date %s;'%(self.created_at) def __str__(self): return self.__unicode__() def _total_items(self): """ Totale n di oggetti """ a = 0 for i in self.items.all: a += i.quantity return a total_items = property(_total_items) class Item(models.Model): cart = models.ForeignKey(Cart) quantity = models.PositiveIntegerField() def __unicode__(self): return u'product %s'%(self.id) def __str__(self): return self.__unicode__() but, when i call the cart property here's what i get in the python console: >>> a.total_items Traceback (most recent call last): File "<console>", line 1, in <module> File "models.py", line 49, in _total_items for i in self.item_set.all: TypeError: 'RelatedManager' object is not callable

• how to deal with async calls in Ajax 4.0(using jquery?)

  - by dexter

  in my code i have done something like this. $.get('/Home/Module/Submit', { moduleName: ModName, moduleParameters: moduleParameters }, function(result) { $("#" + target).html(result); }); when i put alert in the function(result) {..} it shows html perfectly(both in alert and at the 'target'-on the .aspx page) BUT when i remove the alert.. on the page the 'html' don't appear or appear randomly (this method is called multiple times) i think that the 'result' comes to function asynchronously thats why it is not bind with the respective 'div' however in the last iteration it gets bind every time. can we make process stop until data gets bind? or is there any functionality (like alert) which can make data bind.. without disturbing UI (unlike alert)?

• Python 2.6 - I can not write dwords greater than 0x7fffffff into registry using _winreg.SetValueEx()

  - by stasizke

  using regedit.exe I have manually created a key in registry called HKEY_CURRENT_USER/00_Just_a_Test_Key and created two dword values dword_test_1 and dword_test_2 I am trying to write some values into those two keys using following program import _winreg aReg = _winreg.ConnectRegistry(None,_winreg.HKEY_CURRENT_USER) aKey = _winreg.OpenKey(aReg, r"00_Just_a_Test_Key", 0, _winreg.KEY_WRITE) _winreg.SetValueEx(aKey,"dword_test_1",0, _winreg.REG_DWORD, 0x0edcba98) _winreg.SetValueEx(aKey,"dword_test_2",0, _winreg.REG_DWORD, 0xfedcba98) _winreg.CloseKey(aKey) _winreg.CloseKey(aReg) I can write into the first key, dword_test_1, but when I attempt to write into the second, I get following message Traceback (most recent call last): File "D:/src/registry/question.py", line 7, in <module> _winreg.SetValueEx(aKey,"dword_test_2",0, _winreg.REG_DWORD, 0xfedcba98) ValueError: Could not convert the data to the specified type. How do I write the second value 0xfedcba98, or any value greater than 0x7fffffff as a dword value? Originally I was writing script to switch the "My documents" icon on or off by writing "0xf0500174" to hide or "0xf0400174" to display the icon into [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\CLSID{450D8FBA-AD25-11D0-98A8-0800361B1103}\ShellFolder]

• One application instance for two domain name

  - by dervlap

  Hello, I have two web applications in ASP.NET which are quite the same (same business logic, same DAL, same DB scheme but different instance). The only thing that I need to change is the design (logo, color,...) and the text (global and local resource) to adress two separate business sector. We cannot "subdomain" the application because we need the two app "seems to be" independant. Is it a good idea to run only one instance for the 2 web applications. For example : I will have 2 hostnames : mycompagny.com and mycompagny2.com and I will put an HTTP Module which will set a string which will be propagated in my application like 'company' and 'company2'. I will instanciate the dal only once but the connection string will change depending on the string 'company' or 'company2'. Any pros and cons ? Any other alternatives ?

• Add 64 bit offset to a pointer

  - by Novox

  In F#, there's the NativePtr module, but it seems to only support 32 bit offsets for its’ add/get/set functions, just like System.IntPtr does. Is there a way to add a 64 bit offset to a native pointer (nativeptr<'a) in F#? Of course I could convert all addresses to 64 bit integers, do normal integer operations and then convert the result again to nativeptr<'a, but this would cost additional add and imul instructions. I really want the AGUs to perform the address calculations. For instance, using unsafe in C# you could do something like void* ptr = Marshal.AllocHGlobal(...).ToPointer(); int64 offset = ...; T* newAddr = (T*)ptr + offset; // T has to be an unmanaged type Well actually you can't, because there is no "unmanaged" constraint for type parameters, but at least you can do general pointer arithmetic in a non-generic way. In F# we finally got the unmanaged constraint; but how do I do the pointer arithmetic?

• String formatting [str.format()] with a dictionary having a key which is a str() of a number

  - by decimus phostle

  Python neophyte here. I was wondering if someone could help with the KeyError I am getting when using a dictionary for string interpolation in str.format. dictionary = {'key1': 'val1', '1': 'val2'} string1 = 'Interpolating {0[key1]}'.format(dictionary) print string1 The above works fine and yields: Interpolating val1 However doing the following: dictionary = {'key1': 'val1', '1': 'val2'} string2 = 'Interpolating {0[1]}'.format(dictionary) print string2 results in: Traceback (most recent call last): File "test.py", line 3, in <module> string2 = 'Interpolating {0[1]}'.format(dictionary) KeyError: 1L So the problem seems to be in the interpretation of the numeric key as a list index, IMHO. Is there any way to work around this? (i.e. convey that this is instead a dictionary key) TIA and apologies if this question has been asked before(couldn't find anything relevant with my search-fu).

• Changing CCK content-types details results in numerous DB calls for the menu system

  - by Paul Strugger

  Every time I make a change in the details of a content-type it takes too long. I though it had to do with the fact that I had too many content-types and fields (~500), but when I load the devel module to see the queries that take that long I see: Executed 32212 queries in 12267.57 milliseconds. Queries taking longer than 5 ms and queries executed more than once, are highlighted. Page execution time was 55763.32 ms When I see the details I notice that the vast majority of db calls come from the menu system, e.g.: _menu_route menu_local_tasks admin_menu_link_save Why is that? Can I avoid some of these? It doesn't seem logical!

• Utilizing a third party application for GitHub in a django project

  - by Smock

  I'm trying to use a third party application located here: git://github.com/Star2Billing/django-audiofield.git I'm using Aptana Studio as my IDE. I created my project and then I clicked on the project and imported the app from the github location. It looked like it imported. I wanted to check that it imported properly before beginning any real coding so I performed manage.py validate. I got a message that stated: "No module named audiofield". I added the app to my Installed Apps settings and followed the installation instructions. I'm not sure if I'm importing it incorrectly. Also, I'm using virtualenv in Aptana. I'm not sure if this may have added to the problem. Please help.

  I have 1 magento installation with 2 websites. i want to set a subcategory from website 1 as rootcategory of website 2. and i don't know the id of the category, because this is local and has to work on production with other categories. So i can't set the id of the wanted category in code. it must be adjustable in the backend. in system-manage stores- select a store here you can set the rootcategory but there are no subcategories available. is the only solution to build a module to select the id of the category?

• How to distinguish between new and returning anonymous Drupal users?

  - by Matt V.

  Is there an easy way (or a module) in Drupal to distinguish between anonymous users who have never created an account versus those who are returning but are not currently logged in? For non-returning (ie, completely new) users, I'd like to have a front page that is very streamlined and focused on registration as the call-to-action. However, if someone is a returning user but not currently logged in, I'd like to present a lot more information on the front page and have login as the main call-to-action. I realize both pages would still need to have both login and register options available, I just want to make the focus significantly different between the two.

• .NET (C#): Getting child windows when you only have a process handle or PID?

  - by shea241

  Kind of a special case problem: I start a process with System.Diagnostics.Process.Start(..) The process opens a splash screen -- this splash screen becomes the main window. The splash screen closes and the 'real' UI is shown. The main window (splash screen) is now invalid. I still have the Process object, and I can query its handle, module, etc. But the main window handle is now invalid. I need to get the process's UI (or UI handle) at this point. Assume I cannot change the behavior of the process to make this any easier (or saner). I have looked around online but I'll admit I didn't look for more than an hour. Seemed like it should be somewhat trivial :-( Thanks

• name of the class that contains the method code

  I'm trying to find the name of the class that contains method code. In the example underneath I use self.__class__.__name__, but of course this returns the name of the class of which self is an instance and not class that contains the test() method code. b.test() will print 'B' while I would like to get 'A'. I looked into the inspect module documentation but did not find anything directly useful. class A: def __init__(self): pass def test(self): print self.__class__.__name__ class B(A): def __init__(self): A.__init__(self) a = A() b = B() a.test() b.test()

• Getting Error 91

  - by user1695788

  I have a general comprehension issue with classes and objects. What I'm trying to do is pretty simple but I'm getting errors. In the code example below, sometimes the line "Call tables.MethodInCTables" runs fine and sometimes it produces error 91, object not set. IN all cases, I can "see" the method in the type ahead so I know that the code recognizes the "tables" instance and "sees" MethodInCTables. But then I get the run-time error. Sub MainSub() Dim tables as New CTables Call tables.MethodInCTables End Sub ----Class Module = CTables Sub MethodInCTables() ...do something End Sub
