• Trouble creating stored procedure

  - by MatW

  I'm messing around with stored procedures for the first time, but can't even create a simple select! I'm using phpMyAdmin and this is my SQL: DELIMITER // CREATE PROCEDURE test_select() BEGIN SELECT * FROM products LIMIT 10; END // DELIMITER ; After submitting that, my localhost does some thinking for a loooong time and eventually loads a page with no content called /phpmyadmin/import.php. After reloading phpMyAdmin and trying to invoke the procedure: CALL test_select(); I get a "PROCEDURE doesn't exist" error. Any ideas?

• Which is quicker? Memcache or file query? (using maxmind geoip.dat file)

  - by tomcritchlow

  Hi, I'm using Python on Appengine and am looking up the geolocation of an IP address like this: import pygeoip gi = pygeoip.GeoIP('GeoIP.dat') Location = gi.country_code_by_addr(self.request.remote_addr) (pygeoip can be found here: http://code.google.com/p/pygeoip/) I want to geolocate each page of my app for a user so currently I lookup the IP address once then store it in memcache. My question - which is quicker? Looking up the IP address each time from the .dat file or fetching it from memcache? Are there any other pros/cons I need to be aware of? For general queries like this, is there a good guide to teach me how to optimise my code and run speed tests myself? I'm new to python and coding in general so apologies if this is a basic concept. Thanks! Tom

• py2app generates .app with no errors but .app crashes and quits unexpectedly

  - by user3705730

  I am trying to use py2app and it generates .app with no errors but .app crashes and quits unexpectedly. I am trying to do this in virtualenv so I am not sure if that is an issue with all the paths. It works on my computer when all the virtual environments exist but as soon as I close them down, the .app no longer works. The virtual environment I am using has python 2.7.5 Here is my setup.py: """ This is a setup.py script generated by py2applet Usage: python setup.py py2app """ from setuptools import setup APP = ['myApp.py'] DATA_FILES = [] OPTIONS = {'argv_emulation': True, 'packages': ['pulp']} setup( app=APP, data_files=DATA_FILES, options={'py2app': OPTIONS}, setup_requires=['py2app'], )

• Django: where do I call settings.configure?

  - by RexE

  The Django docs say that I can call settings.configure instead of having a DJANGO_SETTINGS_MODULE. I would like my website's project to do this. In what file should I put the call to settings.configure so that my settings will get configured at the right time? Edit in response to Daniel Roseman's comment: The reason I want to do this is that settings.configure lets you pass in the settings variables as a kwargs dict, e.g. {'INSTALLED_APPS': ..., 'TEMPLATE_DIRS': ..., ...}. This would allow my app's users to specify their settings in a dict, then pass that dict to a function in my app that augments it with certain settings necessary to make my app work, e.g. adding entries to INSTALLED_APPS. What I envision looks like this. Let's call my app "rexe_app". In wsgi.py, my app's users would do: import rexe_app my_settings = {'INSTALLED_APPS': ('a','b'), ...} updated_settings = rexe_app.augment_settings(my_settings) # now updated_settings is {'INSTALLED_APPS': ('a','b','c'), 'SESSION_SAVE_EVERY_REQUEST': True, ...} settings.configure(**updated_settings)

• Python win32api not moving mouse cursor in VirtualBox

  - by wes

  I'm trying to use this Python code: import math for i in xrange(500): x = 500 + math.sin(math.pi * i / 100) * 500 y = 500 + math.cos(i) * 100 x, y = int(x), int(y) win32api.SetCursorPos((x, y)) time.sleep(.01) taken from here to move the mouse cursor in an XP VirtualBox. The mouse icon will flicker to the appropriate graphic (when it hits the edge of a window it turns into the <- resize image, for instance), but it doesn't actually move the visible cursor. I can move the mouse around while the code is running. Same result using the ctypes example in the above link. It works fine in the Win7 host. I have Guest Additions installed, if that matters.

• what is a fast way to output h5py dataset to text?

  - by user362761

  I am using the h5py python package to read files in HDF5 format. (e.g. somefile.h5) I would like to write the contents of a dataset to a text file. For example, I would like to create a text file with the following contents: 1,20,31,75,142,324,78,12,3,90,8,21,1 I am able to access the dataset in python using this code: import h5py f = h5py.File('/Users/Me/Desktop/thefile.h5', 'r') group = f['/level1/level2/level3'] dset = group['dsetname'] My naive approach is too slow, because my dataset has over 20000 entries: # write all values to file for index in range(len(dset)): # do not add comma after last value if index == len(dset)-1: txtfile.write(repr(dset[index])) else: txtfile.write(repr(dset[index])+',') txtfile.close() return None Is there a faster way to write this to a file? Perhaps I could convert the dataset into a NumPy array or even a Python list, and then use some file-writing tool? (I could experiment with concatenating the values into a larger string before writing to file, but I'm hoping there's something entirely more elegant)

• Python: how to run several scripts (or functions) at the same time under windows 7 multicore processor 64bit

  - by Gianni

  sorry for this question because there are several examples in Stackoverflow. I am writing in order to clarify some of my doubts because I am quite new in Python language. i wrote a function: def clipmyfile(inFile,poly,outFile): ... # doing something with inFile and poly and return outFile Normally I do this: clipmyfile(inFile="File1.txt",poly="poly1.shp",outFile="res1.txt") clipmyfile(inFile="File2.txt",poly="poly2.shp",outFile="res2.txt") clipmyfile(inFile="File3.txt",poly="poly3.shp",outFile="res3.txt") ...... clipmyfile(inFile="File21.txt",poly="poly21.shp",outFile="res21.txt") I had read in this example Run several python programs at the same time and i can use (but probably i wrong) from multiprocessing import Pool p = Pool(21) # like in your example, running 21 separate processes to run the function in the same time and speed my analysis I am really honest to say that I didn't understand the next step. Thanks in advance for help and suggestion Gianni

• ASP.NET Long Process and Sending updates to Browser

  - by user204588

  Hello, I've asked this before but I was hoping for another answer and perhaps some code samples because I've been having a difficult time with this. I have an asp.net page. The user hits the "Run" button and I have code IN AN ASSEMBLY, not in the APP_CODE folder that is called and runs a long process that moves product info from a file into the database. While the user waits, I would like them to see status updates like what product the import process in on and status info. I'm assuming I'd break off into another thread and use Ajax but I have no idea how to do this. Some code samples would be very helpful, thanks.

• Flash Builder keeps losing my imported classes...arghh

  - by pfunc

  I've been having this really annoying thing happen the past few days, that has happened before but not as frequently. I create a project in Flash Builder, import some classes, and then on occasion it keeps erasing those classes. So then I get errors in a lot of my datatypes, have to go back through my document and retype the datatype so that it reimports the class. What could be causing this? I know flash builder can be a bit buggy at times, but wasn't sure if someone else has had this problem and knows what might be causing it.

• Incremental Compilation in Eclipse. ASTNode-s and SVN versioning

  - by Alex

  Hi there, I am building up some statistics after analyzing the source code in eclipse. But the overall process is too slow because i rebuild my model every time from scratch after each compilation. I am looking for a way to get only the changed parts of the code (as ASTNodes) and to rebuild just that part of my model. I suppose that even the changed compilation units and not the exact code elements would be enough after the user compiles and still would be a nice optimization. I am sure eclipse is capable of knowing what code elements are changed (and even to know their semantics), because when I use the subclipse plugin my changes are ordered by a code element (an import, a method, a variable declaration, etc). Well.. at least that plugin is capable of knowing that info. Thanks in advance

• Unstyled web page in IE6. Not FOUC

  - by Illes Peter

  I have a very interesting issue with one of the websites I created. It renders fine in Safari, Chrome, Opera, FF, IE7&8 but IE6 does not seem to recognize my stylesheet. I'm not using @import for loading, so it's not a case a FOUC. The website is using Wordpress but never had an issue like this before with WP. I might be missing out on something stupid here, can find the problem though. Any help, suggestion would be very much appreciated. The website is: http://www.magashegyiturak.ro

• How to disable translations during unit tests in django?

  - by Denilson Sá

  I'm using Django Internationalization tools to translate some strings from my application. The code looks like this: from django.utils.translation import ugettext as _ def my_view(request): output = _("Welcome to my site.") return HttpResponse(output) Then, I'm writing unit tests using the Django test client. These tests make a request to the view and compare the returned contents. How can I disable the translations while running the unit tests? I'm aiming to do this: class FoobarTestCase(unittest.TestCase): def setUp(self): # Do something here to disable the string translation. But what? # I've already tried this, but it didn't work: django.utils.translation.deactivate_all() def testFoobar(self): c = Client() response = c.get("/foobar") # I want to compare to the original string without translations. self.assertEquals(response.content.strip(), "Welcome to my site.")

• scala 2.8 breakout

  In Scala 2.8, there is an object in scala.collection.package.scala: def breakOut[From, T, To](implicit b : CanBuildFrom[Nothing, T, To]) = new CanBuildFrom[From, T, To] { def apply(from: From) = b.apply() ; def apply() = b.apply() } I have been told that this results in: > import scala.collection.breakOut > val map : Map[Int,String] = List("London", "Paris").map(x => (x.length, x))(breakOut) map: Map[Int,String] = Map(6 -> London, 5 -> Paris) What is going on here? Why is breakOut being called as an argument to my List?

• Hibernate deletion issue

  - by muffytyrone

  I'm trying to write a Java app that imports a data file. The process is as follows Create Transaction Delete all rows from datatable Load data file into datatable Commit OR Rollback if any errors were encountered. The data loaded in step 3 is mostly the same as the data deleted in step3. The deletion is performed using the following DetachedCriteria criteria = DetachedCriteria.forClass(myObject.class); List<myObject> myObjects = hibernateTemplate.findByCriteria(criteria); hibernateTemplate.deleteAll(myObjects); When I then load the datafile, i get the following exception nested exception is org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: The whole process needs to take place in transaction. And I don't really want to have to compare the import file / data table and then perform an insert/update/delete to get them into sync. Any help would be appreciated.

• Data Warehouse: One Database or many?

  - by drrollins

  At my new company, they keep all data associated with the data warehouse, including import, staging, audit, dimension and fact tables, together in the same physical database. I've been a database developer for a number of years now and this consolidation of function and form seems counter to everything I know. It seems to make security, backup/restore and performance management issues more manually intensive. Is this something that is done in the industry? Are there substantial reasons for doing or not doing it? The platform is Netezza. The size is in terabytes, hundreds of millions of rows. What I'm looking to get from answers to this question is a solid understanding of how right or wrong this path is. From your experience, what are the issues I should be focused on arguing if this is a path that will cause trouble for us down the road. If it is no big deal, then I'd like to know that as well.

• Can someone explain this java interface to me please?

  - by Karl Patrick

  I realize that the method run must be declared because its declared in the runnable interface. But my question comes when this class runs how is the Thread object allowed if there is no import call to a particular package? how does runnable know anything about Thread or its methods? does the runnable interface extend the thread class? Obviously i dont understand interfaces very well. thanks in advance. class PrimeFinder implements Runnable{ public long target; public long prime; public boolean finished = false; public Thread runner; PrimeFinder(long inTarget){ target = inTarget; if(runner == null){ runner = new Thread(this); runner.start() } } public void run(){ } }

• XML Schema Header & Namespace Config

  - by zharvey

  Migrating from DTD to XSD and for some reason the transition is a bumpy one. I understand how to define the schema once I'm inside the <xs:schema> root tag, but getting past the header & namespace declaration stuff is proving to be especially confusing for me. I have been trying to follow the well-laid out tutorial on W3S but even that tutorial seems to assume a lot of knowledge up front. I guess what I'm looking for is a King's English explanation of which attributes do what, where they go, and why: xmlns xmlns:xs xmlns:xsi targetNamespace xsi:schemaLocation And in some cases I see different variations of these elements/attributes, such as xsi which seems to have two different notations like xsi:schemaLocation="..." and xs:import schemaLocation="...". I guess between all these slight variations I can't seem to make heads or tails of what each of these does. Thanks in advance for bringing any clarity to this confusion!
