• Python IDE built into Visual Studio 2008?

  - by Thomaschaaf

  Hi I develop in Visual Studio 2008 a lot and would like to find an addin like vsphp which enables intellisense and debugging in Visual Studio. Is IronStudio what I am looking for? As far as I understand IronStudio is a Plugin for .NET. If there is no Plugin for Visual Studio 2008 whats a great IDE for a python newbee who loves Visual Studio (hate netbeans and eclipse sorry just don't feel the love) Also if IronPython Studio is an IDE do I want the Isolated or Integrated Version? I don't seem to understand the name. I installed integrated and got this: http://dl.getdropbox.com/u/5910/Jing/2009-02-11_1750.png :( no console like here: http://www.codeplex.com/IronPythonStudio

• How do you use pip, virtual_env and Frabric to handle deployement?

  - by e-satis

  What are your settings, your tricks, and above all, your workflow. These tools are great but they is still no best practices attached to their usage, so I don't know what is the most efficient way. Do you use pip bundles or always download? Do you set up Apache/Cherokee/MySQl by hand or do you have a script for than. Do you put everything in virtual_env and use --no-site-package? Do you use one virtual_env for several projects? What do you use Fabric for (which part of your deployment do you script)? Do you put your Fabric scripts in on the client or the server? How do you handle database and media file migration? Do you even need a build tool such as SCons? What are the steps of your deployment? How often do you perform each of them? etc.

• Does the WCF framework support the XSD IDREF restriction?

  - by Gerard

  A nice feature in XSD is the IDREF restriction, e.g.: <xs:restriction base="xs:IDREF"> <xs:pattern value="[0-9a-zA-Z\-]+"/> </xs:restriction> I used this restriction with great benefit in a Java JAXWS-project. An object serialized in a SOAP XML datamodel can hold a reference (pointer) to another object in the same SOAP message. I want to try the same approach in a C# WCF-project, can it be done? On the web site Data Contract Schema Reference I can see e.g. Id ignored, Ref forbidden, but I am not sure whether I understand what that means.

• How to replace 'dash' with 'underscore' in an IIRF rule?

  - by jessegavin

  I have a web app which serves images based on the subdomain. We wanted to provide our users with a url like this: http://{username}.domain.com/images/myimage.jpg Instead of what we used to have: http://www.reallylongdomainname.com/users/{username}/images/myimage.jpg This makes the url shorter and less 'snoopable'. So I set up an IIRF .ini file to do some url rewriting and it works great except for the fact that some of our users folders have an underscore. And from what I've read, underscore is not a valid character in a domain name (even though IIS supports it). I want to know how I could do a find and replace in the $1 back reference so that a url like this: http://some-user.domain.com/... Could be rewritten to this: /users/some_user/.. Here's my IIRF rule. RewriteCond %{HTTP_HOST} ^(?!www)([^\.]+)\.domain\.com RewriteRule ^/(.*)$ /users/*1/$1 [L,I] Thanks for any help.

• How to auto-restart a python script on fail?

  - by norm

  This post describes how to keep a child process alive in a BASH script: http://stackoverflow.com/questions/696839/how-do-i-write-a-bash-script-to-restart-a-process-if-it-dies This worked great for calling another BASH script. However, I tried executing something similar where the child process is a Python script: #!/bin/bash PYTHON=/usr/bin/python2.6 function myprocess { $PYTHON daemon.py start } NOW=$(date +"%b-%d-%y") until myprocess; do echo "$NOW Prog crashed. Restarting..." >> error.txt sleep 1 done Now the behaviour is completely different. It seems the python script is no longer a child of of the bash script but seems to have 'taken over' the BASH scripts PID - so there is no longer a BASH wrapper round the called script...why?

• Rearranging parts of the URL result from link_to in Rails

  - by mathee

  This is how I'm doing it now: link_to "Profile", :controller => "profiles", :action => "asked", :id => @profile # => <a href="/profiles/asked/1">Profile</a> Does it make more sense for the URL to be <a href="/profiles/1/asked">Profile</a>? Profile 1 asked some number of questions, so it makes more sense to me for the URL to look like: /:controller/:id/:action. If you agree, how do I accomplish this? If you don't agree, please let me know why. (I'm new to Ruby on Rails, so I'm still getting used to MVC conventions.) Any advice would be great!

• What if I have an API method and a contoller/view method with the same name in RoR?

  - by Chad Johnson

  Suppose I want to be able to view a list of products on my site by going to /product/list. Great. So this uses my 'list' view and outputs some HTML which my web browser will render. But now suppose I want to provide a REST API to my client where they can get a list of their products. So I suppose I'd have them authenticate with oAuth and then they'd call /product/list which would return a JSON array of their products. But like I said earlier, /product/list displays an HTML web page. So, I have a conflict. What is normal practice as far as providing APIs in Rails? Should I have a subdirectory, 'api', in /app/controller, and another 'product' controller? So my client would go to /api/product/list to get a list of their products? I'm a bit new to RoR, so I don't have the best grasp of the REST functionality yet, but hopefully my question makes sense.

• Paypal IPN Confirmation Screen immediately after redirect without reload

  - by Email

  Hi I made a script for IPN which works great but how can i immediately notify the user? I mean paypal redirects the customer to a custom-page i can define, simultanously my ipn.php checked the status, BUT how can i immediately tell the customer on this custom-page that it was successful or not. this custom-page does somehow has to know that this is the customer-xyz which made the ipn-verified!!! payment xyz, but how? i think also this custom-page redirect should wait the 5 seconds because php does only process files/request on-loads... so after 5 seconds the ipnscript surely did complete. Sorry if this question is too newby but i dont know how to notify the customer about the (ipn-verified!!!) payment-status immediately. How do you do this? Thanks so much

• Install .exe software application on remote machines.

  - by coral_reef

  Hi, I modified this script from the net, which is suppose to install .exe applications for remote machines: $m = Read-Host "Enter machine name" $File = "c:\temp\office2007sp2-kb958194-fullfile-en-us.exe" $product = [WMICLASS]"\$m\ROOT\CIMV2:win32_Process" $product.Create($File) When I run this script, I have noticed that this program promptly creates a process in the remote machine with the application name office2007sp2-kb958194-fullfile-en-us.exe. This can be checked in the task manager also. But other than that, there is no way to find out if this is getting installed in the remote machine or not. Is there a way to find out, if the installation is really happening? Or does this script actually works? Any help will be great! Reagrds Arindam

• table cell background color change problem

  - by Mellon

  I work on another guy's code, and I try to change the table cell background color when mouse over the cell, and change back to the original background color when mouse leave. I use the following code: var bgcolor=$(".cell-el").css("background-color") $(".cell-el").hover( function(){ $(this).css("background-color", "#3c3c36")}, //mouse enter, bg-color change function(){ $(this).css("background-color", bgcolor) // mouse leave, bg-color change back }) Things are working fine, EXCEPT that when mouse first time enter the cell, the cell background color is not changed to "#3c3c36", but when mouse leave the cell after first entering and enter in the cell again, the cell's background color changed to "#3c3c36". That's the cell color never change for mouse first enter, after that, everything is working great. What's could be the cause of this problem?

• Is it possible to force ignore the :hover pseudoclass for iPhone/iPad users?

  - by christophercamps

  I have some css menus on my site that expand with :hover (without js) This works in a semi-broken way on iDevices, for example a tap will activate the :hover rule and expand the menu, but then tapping elsewhere doesn't remove the :hover. Also if there is a link inside the element that is :hover'ed, you have to tap twice to activate the link (first tap triggers :hover, second tap triggers link). I've been able to make things work nicely on iphone by binding the touchstart event. The problem is that sometimes mobile safari still chooses to trigger the :hover rule from the css instead of my touchstart events! I know this is the problem because when I disable all the :hover rules manually in the css, mobile safari works great (but regular browsers obviously don't anymore). Is there a way to dynamically "cancel" :hover rules for certain elements when the user is on mobile safari? I'm using jQuery.

• javac - differences between classpath and sourcepath options

  - by Alex

  Hi, I read the Sun documentation and a lot of Q/A on SO but I'm still a little bit confuse regarding the differences between the javac options -cp and -sourcepath. Let say I have this directory structure: c:\Java\project1\src (where the .java source files are) c:\Java\project1\bin (where the .class will be or are already) The class source MainClass.java is in a package "com.mypackage" and the directory structure is ok in src. I'm in the project1 directory. I run c:\Java\Project1\javac -d bin -sourcepath src src/com/mypackage/MainClass.java or c:\Java\Project1\javac -d bin -classpath src src/com/mypackage/MainClass.java and I obtain the same result. In verbose mode, the search path for source files is src in both cases. If anybody could help me figure out the specifics of these options, it would be great. Thank you.

• Does anyone have a backup strategy for SQL Azure databases?

  - by Pete

  I'm using SQL Azure on a project and it works great. The problem is that the usual backup features do not exist. I have exported the database a couple of times using SQLAzureMW ( http://sqlazuremw.codeplex.com/ ) but this tool is now choking trying to download the database data with bcp. In any case, it's not as nice a solution as SQL Server backups. Is anyone aware of a commercial or open source tool, or other technique, for making reliable backups of SQL Azure databases? This is really a showstopper.

• Good book suggestions for building enterprise software

  - by ncoder

  Enterprise software are built using technologies/softwares/terminologies/APIs such as EJB, JBoss, Seam, Hibernate(JPA), Maven, Eclipse, Spring, JTS, JMS, JNDI etc. I know there are great books out there for each of these individually, however can someone suggest a book or two that covers all (or most of) these topics in lesser detail and gives examples of how these are integrated? I have intentionally left the client side stuff out because its highly unlikely a single book would cover that much. If anyone knows of a book (or books) that cover most of or various combinations (like EJB, Hibernate, Spring and Seam) of these technologies, please do suggest the same. The idea is not to become an expert in all however know about them in reasonable detail and why each one is required.

• Regex: absolute url to relative url (C#)

  - by splatto

  I need a regex to run against strings like the one below that will convert absolute paths to relative paths under certain conditions. <p>This website is <strong>really great</strong> and people love it <img alt="" src="http://localhost:1379/Content/js/fckeditor/editor/images/smiley/msn/teeth_smile.gif" /></p> Rules: - If the url contains "/Content/" I would like to get the relative path - If the url does not contain "/Content/", it is an external file, and the absolute path should remain Regex unfortunatley is not my forte, and this is too advanced for me at this point. If anyone can offer some tips I'd appreciate it. Thanks in advance.

• internet explorer 7 iframe unloads when going back

  - by André

  Hi this is my first post here, so please be kind ;-) i'm implementing a browser history manager, just like rsh or yui browser history manager. The idea was not to constantly poll the url hash of a hidden iframe, but to capture the onscroll event of an iframe, when it scrolls to an anchor name on an urlhashchange. So on every click i add an new anchor to iframe and set the iframe's hash to the anchors name. When pressing the back or forward button the frame scrolls to the previous or next anchor and the onscroll event is fired. That works great on firefox 3.0+, IE6 and Opera but on IE7 when hiting the back button the frame unloads and loses all its anchors. If anyone has an idea why this is happening or even a fix for this "bug", please i'm slowly going insane over this. thanks in advance btw the onscroll idea comes from: http://www.zachleat.com/web/2008/08/21/onhashchange-without-setinterval/

• pitchbend (varispeed) audio with iPhone SDK's AudioUnit

  - by fetzig

  hi, I'm trying to manipulate the speed (and pitch) of a sound while playing. so i played around with iphone sdk's AudioUnit. downloaded iPhoneMultichannelMixerTest and tried to add an AUComponent to the graph (in this case a formatconverter). but i get (pretty soon) following error when building: #import <AudioToolbox/AudioToolbox.h> #import <AudioUnit/AudioUnit.h> ... AUComponentDescription varispeed_desc(kAudioUnitType_FormatConverter, kAudioUnitSubType_Varispeed, kAudioUnitManufacturer_Apple); ^^ error: 'kAudioUnitSubType_Varispeed' was not declared in this scope. any ideas why? the documentation on this topic doesn't help me at all (just api doc isn't very helpful when having no clue about the concept behind). there are no examples on how to wire these effects together and manipulating there properties...so maybe i'm totally wrong, anyway any hint is great. thx for help.

• Retrieve Button value with jQuery

  - by Simon Hutton

  A simple one, I'm trying to retrieve the value attribute of a button when its been pressed using jQuery, here's what I have: <script type="text/javascript"> $(document).ready(function() { $('.my_button').click(function() { alert($(this).val()); }); }); </script> <button class="my_button" name="buttonName" value="buttonValue"> Button Label</button> In Firefox my alert displays 'buttonValue' which is great but in IE7 it displays 'Button Label'. What jQuery should I use to always get the button's value? Or should I be using a different approach? Many thanks. ANSWER: I'm now using <input class="my_button" type="image" src="whatever.png" value="buttonValue" />

• Searching with Linq

  - by Phil

  I have a collection of objects, each with an int Frame property. Given an int, I want to find the object in the collection that has the closest Frame. Here is what I'm doing so far: public static void Search(int frameNumber) { var differences = (from rec in _records select new { FrameDiff = Math.Abs(rec.Frame - frameNumber), Record = rec }).OrderBy(x => x.FrameDiff); var closestRecord = differences.FirstOrDefault().Record; //continue work... } This is great and everything, except there are 200,000 items in my collection and I call this method very frequently. Is there a relatively easy, more efficient way to do this?

• Custom login in Django

  - by alpgs

  Django newbie here. I wrote simplified login form which takes email and password. It works great if both email and password are supplied, but if either is missing i get KeyError exception. According to django documentation this should never happen: By default, each Field class assumes the value is required, so if you pass an empty value -- either None or the empty string ("") -- then clean() will raise a ValidationError exception I tried to write my own validators for fields (clean_email and clean_password), but it doesn't work (ie I get KeyError exception). What am I doing wrong? class LoginForm(forms.Form): email = forms.EmailField(label=_(u'Your email')) password = forms.CharField(widget=forms.PasswordInput, label=_(u'Password')) def clean_email(self): data = self.cleaned_data['email'] if not data: raise forms.ValidationError(_("Please enter email")) return data def clean_password(self): data = self.cleaned_data['password'] if not data: raise forms.ValidationError(_("Please enter your password")) return data def clean(self): try: username = User.objects.get(email__iexact=self.cleaned_data['email']).username except User.DoesNotExist: raise forms.ValidationError(_("No such email registered")) password = self.cleaned_data['password'] self.user = auth.authenticate(username=username, password=password) if self.user is None or not self.user.is_active: raise forms.ValidationError(_("Email or password is incorrect")) return self.cleaned_data

• where to store helper functions?

  - by ajsie

  i've got a lot of functions i create or copy from the web. i wonder if i should store them in a file that i just include into the script or should i store each function as a static method in a class. eg. i've got a getCurrentFolder() and a isFilePhp() function. should they be stored in a file as they are or each in a class: Folder::getCurrent() File::isPhp(); how do you do? i know this is kinda a "as u want" question but it would be great with some advices/best practices thanks.

• Placement of axis labels at minor breaks with ggplot2

  - by JAShapiro

  I am using ggplot2 to do some plotting of genomic data, so the basic format is that there is a chromosome and a position along it. I convert the positions to be on a continuous scale, then put the breaks at the boundaries of the chromosomes with: scale_x_continuous("Genome Position", breaks = c(0, cumsum(chromosome_length))) That looks great, as far as the actual plotting is concerned, but the labels are then put at the start and end of the chromosomes. I would like them to be centered along each chromosome, at the position where the minor break is drawn by default. Is this possible?
