In most comparisons between the languages, Python is the obvious answer, because you don't have to mess with memory management and all that.
However, with Qt I'm not so sure. It provides enough added features to C++ that (from what I can tell) a line of Python code is roughly equal to a line of C++ code most of the time (excluding some additional things like class definitions and structure components). Qt does nearly all the memory management for you as long as you stick with its classes, and provides equivalents to the nice containers you would find in Python.
I've always preferred statically typed languages, but have gotten on the Python bandwagon for various reasons. If programmer productivity is similar with C++, however, I may jump back that way for its other benefits -- more efficient code and fewer dependencies for users to install.

With Python code you don't have to bother with the MOC, portability, build times, etc. Just compare the work involved in implementing a QT slot in C++ vs. PyQT or PySide, e.g. I find it to be much less of a pain to deal with widgets this way (much greater productivity). You can still invoke C++ code from Python in cases where you need the added performance.
If you do use a combination, consider extending Python rather than embedding it. Python is generally better suited to embed C/C++ code than to be embedded into a C/C++ system. It also tends to make more sense that way as applications are generally composed of far more mundane, non-performance critical code than performance-critical code, so writing your application primarily as a python application with C/C++ functions attached to it fits that kind of system design better. | 5 | 47 | 0 | Trying to dive into Qt big time but haven't done a large project with it yet.

Best way for you to arrive at the answer would be to write a simple project first in C++ and then same project in python and compare, but that could be biased towards python as after coding the project once you may find it easy in Python, so try another project too and first do it in Python and then in C++. | 5 | 47 | 0 | Trying to dive into Qt big time but haven't done a large project with it yet.

Yes, people will say that Python is more productive without a reason. Some of the answers mention that you do not have to recompile. I will give you some more details
Python is one layer of abstraction over C++, so you can think and express your designs with less code. Your program might not run as fast, but sure you express faster in code what you want.
The most common case is when you launch your application, load some files, setup the environment and open a dialog. There you notice that a button is not working or where it should be. Now that is the point where most people close the application, bind one slot here, one signal there... and start the application, load the files, setup... with python you just write the code and fire up the dialog again, not the whole application. I do not know about you, but that type of task is what I do most of the time with Qt
Python gives you something that C++ does not have: introspection. You can explore a running program and pull out information about its components on runtime. Qt gives you partially this. You have that MOC layer where meta properties and meta information can be attached to Qt objects. All parts of a Python program can be introspected. Many people debugging Python code, or trying to understand how it works, are addicted to this for a good reason | 5 | 47 | 0 | Trying to dive into Qt big time but haven't done a large project with it yet.

So, baring in mind this is going to be a pretty intensive app, I'd like to hear your opinions on the following:
Generic web frameworks
ORM/Database Layer (perhaps to work with MongoDB)
RESTful API w/ oAuth/xAuth authentication
Testing/BDD support
Message queue (I'd like to keep this in Python if possible)
The API is going to need to interface with a Clojure app to handle some internal data stuff, and interface with the message queue, so if it's not Python it'd be great to have some libraries to it.
TDD/BDD is very important to me, so the more tested, the better!
It'll be really interesting to read your thoughts on this. Much appreciated.

I had trouble installing python and python libraries on osx, and this is what I ended up doing to fix it:
Using macports I installed python26 and python_select. Then use python_select to change from the default python26-apple to python26 (which is from macports). Now when you use macports to install any python26 library it will just work.
One of the main drawbacks of this approach is that macports installs everything from source, which is slow and buggy compared to using pre-build binaries, but for me it's worth it to be able to manage most of my FOSS software through macports. | 1 | 0 | 0 | I would like to install:
A. Mod python on a regular Macbookpro (MacOSX 10.6.4)
B. And MySQL for Python on the same computer.
And the installation is constantly failing.
Question 1: Is there a tutorial on how to achieve this on Mac OS?
I also hoped that I could use Macports for this.
I had bad experience with Macports and installing python.
I am sure this is due to my not understanding the concept of:
ports
profile (pythonpath)
Question 2: What would I have to write in the .profile to make packages be recognized by python?
Question 3: What exactly is a port?
In general it would be awesome to get an understanding on how to install packages in python quick and effectively.
Also the build in version of Python by Apple seems to have settings, that, if changed can make your life difficult.
Question 4: Any detailed experience or advice on this issues would he very helpful.

Things from which you can make a guess:
regional and language settings (but a German in the USA can be using de_DE)
time zone (but are we in NYC or in Brazil? same TZ offset; in your case, (PDT/EDT) and CET is different enough)
internal IP address (assuming your offices have different internal addressing (e.g. "10.5.20.0/24 - Germany, 192.168.4.0/24 - USA"; what of the VPNs, what about unconnected devices?)
external IP address (if you need accuracy on the scale USA/Europe, this is passable; of course, VPNs mess this up, and question says external connectivity may not be available)
keeping a list of which computer is where (messy and hard to maintain)
keeping a list of which user is where
remembering where this computer was on last program start (and whether it was corrected manually)
By assigning a score to each of these things, and checking for each, you could get a probability score where the computer is. You might get some incorrect guesses though, so make a manual override, too.
The combined score might be quite accurate in the general case; what you need to do is find the edge and corner cases, then find some way to identify those. | 1 | 3 | 0 | My client has two offices in Germany and USA and a python program should recognize the office location.

you have a producer publishing to a direct exchange;
you have a queue bound to that exchange;
you have many subscribers, all consuming from the above queue.
This works perfectly for sending a message to an arbitrary subscriber (thus sort-of load balancing), but you want to be able to send some messages to ALL the subscribers.
You could do this with a fanout exchange and an extra queue for each subscriber:
your producer publishes system-wide messages to a fanout exchange;
there's a queue for each subscriber bound to that exchange;
each subscriber first attempts to consume from this queue; if it doesn't succeed, it tries to consume from the common queue you currently use. | 1 | 0 | 0 | Consider a tier of N-many subscribers, all connected to a direct exchange using identical queue name and routing key values. This creates a load-balanced system where an inbound message is send round-robin to 1 of the subscribers. This works very well for dealing with scale-out issues as more subscribers can be added as load increases and can later be withdrawn if necessary.
Now consider the requirement of being able to send messages to ALL subscribers in that tier, without knowing how many there are (for example a "reset your state" or "shutdown now please" administrative message). Is there any way to do this in rabbitmq? If this isn't possible, is there a better approach?

Gobs of documentation and forum help is there for that. I like the idea of customizing the admin, but honestly, I have been doing it for awhile on a project and time and time again I think to myself, if this was built in the standard MVC (or MTV) manner with free templates online, copied admin ones, or some professionally made ones, and built with the plethora of addons and my code, it would be much easier!!! And, when you decide that request/response isn't cutting it, and you want to add lots of JavaScript, you'll be glad. I know. I have had to put all sorts of JavaScript on our Admin project.

All my basic blocks are regular expressions, so reusing them would be nice.
I know I can't have everything so I am willing to give up on some of the features I have today to get to the requested 10× performance.

You can access (read) any PoD or python specific object (such as an array) without causing failure in a multi-threaded program trying the same thing at the same time, but you can not change them and accept thread integrity.
My question is about classes. I have a server that is delegating database access to different threads, however I want them to be able to all access an instance of a class that handles response generation. However, I'm wondering if this class is thread-safe (I wish to avoid creating multiple instances), the thread does not change any instance variables (i.e. self.something = (something)) every function uses its own local variables (they do access class instance variables but does not change them), so to sum it up: my question is if many threads can use the same instance and call functions at the same time. | Thread safety in Python (Question how it works) | 1.2 | 0 | 0 | 399 |

One of the limitations in App Engine is that you cannot write directly to the filesystem from your app. Static files would be things like HTML, CSS, javascript and images that are global to your application, and get uploaded manually when you deploy. They are uploaded to and served from different servers than the ones that handle dynamic content.
Since you can't write to the filesystem from your app, files uploaded by users must be saved to the datastore as blobs. These are not considered static files. As others have mentioned, you can use S3 or the Blobstore API, however both of these require billing. With the free quotas, each entity can be up to 1MB, and each HTTP request and response can be up to 10MB. Using standard entities with a BlobProperty, you can easily store and serve dynamically uploaded files up to 1MB, or 10MB if you want to get fancy and store your blob in slices across multiple entities. | 1 | 3 | 0 | I am developing an application in google application engine which would have a user profiles kind of feature. I was going through the Google App's online tutorial where I found that the maximum number of static files (app files and static files) should not exceed 3000. I am afraid whether the user's would be able to upload their images when the number of users increase. Is this limitation for the Free Quota only or its even after billing. In the document, its mentioned as the additional limit than the Free Quota.
Please suggest.

I seriously considered matlab/octave, but when reading the octave API and matlab API, they are different enough that I'd need to build separate interfaces for each (or get very creative with macros). With python I end up with a single, easier to maintain codebase for the front end, and it is used by just about everyone we know. Thanks for the tips/feedback everyone! | 2 | 6 | 1 | The simulation tool I have developed over the past couple of years, is written in C++ and currently has a tcl interpreted front-end. It was written such that it can be run either in an interactive shell, or by passing an input file. Either way, the input file is written in tcl (with many additional simulation-specific commands I have added). This allows for quite powerful input files (e.g.- when running monte-carlo sims, random distributions can be programmed as tcl procedures directly in the input file).
Unfortunately, I am finding that the tcl interpreter is becoming somewhat limited compared to what more modern interpreted languages have to offer, and its syntax seems a bit arcane. Since the computational engine was written as a library with a c-compatible API, it should be straightforward to write alternative front-ends, and I am thinking of moving to a new interpreter, however I am having a bit of a time choosing (mostly because I don't have significant experience with many interpreted languages). The options I have begun to explore are as follows:
Remaining with tcl:
Pros:
- No need to change the existing code.
- Existing input files stay the same. (though I'd probably keep the tcl front end as an option)
- Mature language with lots of community support.
Cons:
- Feeling limited by the language syntax.
- Getting complaints from users as to the difficulty of learning tcl.
Python:
Pros:
- Modern interpreter, known to be quite efficient.
- Large, active community.
- Well known scientific and mathematical modules, such as scipy.
- Commonly used in the academic Scientific/engineering community (typical users of my code)
Cons:
- I've never used it and thus would take time to learn the language (this is also a pro, as I've been meaning to learn python for quite some time)
- Strict formatting of the input files (indentation, etc..)
Matlab:
Pros:
- Very power and widely used mathematical tool
- Powerful built-in visualization/plotting.
- Extensible, through community submitted code, as well as commercial toolboxes.
- Many in science/engineering academia is familiar with and comfortable with matlab.
Cons:
- Can not distribute as an executable- would need to be an add-on/toolbox.
- Would require (?) the matlab compiler (which is pricy).
- Requires Matlab, which is also pricy.
These pros and cons are what I've been able to come up with, though I have very little experience with interpreted languages in general.

Think about the date example—instead of passing around a date object, instead you pass around a str of the format "2010-01-01". In order to work with that data, every user of the class needs to know not only that it's a str which represents a date, but what the format of that string is. In other words, you haven't gained anything. Worse, you lose the ability to pass a datetime object into the widget (unless you take extra steps to deal with that case).

Each field has an associated widget which defines how the field is rendered.
When the widget is created, it is passed in a (default) value so that it knows what to display the first time it is rendered. After the form is submitted, the widget is asked for a value. I delegate this to the widget rather than just nabbing it from the POST data because a widget may consist of several HTML inputs (think of a month/day/year selector). Only the widget knows how to mash these together into one value.
Problem is, I don't know if I should have the widget always accept a string, and always return a string for consistency, or accept and return a data type consistent with its purpose (i.e., a date selector should probably return a DateTime object).
The philosophy behind my form class is "mix and match". You choose what widget you want, and what validators/formatters/converters you want to run on it.

So the answer is no, you can't store a cookie that is independent of the browser with Django (or any other web framework).
A possible solution is, if your visitor need to log to your site, you can store the info on the server, probably in a database. But if you don't required users to be log in, it will not work. Your other solution is to use Flash only to store the cookies. | 2 | 0 | 0 | Is there any way in django to store cookies which is independent to browser ?

Thanks & happy blendering.
note 1:
i have the 3 points / vertices (p1,p2,p3 ) on the sphere for a spherical triangle
but i need to trace the edges on the sphere in 3D
so what would be the equations needed to determine all vertices between each points pair of the triangle on the sphere
3 edges from p1 to p2 - p2 to p3 and o3 to p1
i know it has something to do with the Great circle for Geodesic on a sphere
but cannot find the proper equations to do the calculations in spherical coordinates!
Thanks
Great circles
it would have been interesting to see a solution with great circle and see tehsolution in spherical coordinates directly !
but still interesting to do it in the euclidiens space
Thanks
ok i used this idea of line segment between 2 points
but did not do it as indicated before
i used an alternative method - Bezier line interpolation**
i parametrize the line with a bezier line
then subdivided and calculated as shonw ealier the ratio and angle for each of the subdivided bezier point on the chord
and it works very well and very precise
but it would be interesting to see how it is done whit the earlier method
but not certain how to do the iteration loop?
how do you load up the python code here
just past it with Ctrl-V?
Thanks and happy 2.5
i do use the blenders' forum
but no guaranti to get a clear answer all the time!
that's why i tried here - took a chance
i did the first edge seems to work
now got to make a loop to get multi segment for first edge and then do the other edges also

i open here a post on bezier triangle patch
i know it's not a usfull tool
but just to show how it is done
have youeseen a python sript to do theses triangel patch

Django is a framework, while Drupal is a full scale CMS. One of the powerful things about Drupal, is how it handles content. Every piece of content is a node, and it lets developers make modules that can add to a node's functionality.
Django is a great tool to, but it's strength is more the ease of development, that lets you create applications very fast. That is what it was built for after all. It would be hard to make something CCK and Views like with Django, and I don't think it would make much sense either. I find that when developing with Django, you can very quickly create most CCK and views things, withe Django models and the orm. You can't do it in a GUI, but that was never the goal of Django. The admin interface also reflects that, as it is good mainly for one thing. Handling content, CRUD style operations.

But in no ways radio buttons and check boxes action programming. You will have to put your building blocks together and indulge some python programming. I found myself spending more time loading extra modules and themes tweaking in Drupal, than putting together a full blown site in Django, maybe because, I own many libraries wrote several times and improved over time, for cases encountered over and over. I focus only on new or cutting edge things. Both approaches are ok as long as you know what you want to go. The hard fact is that for a CMS that want to attract non programmers peoples if you want to build great sites, you have to be good in php/mysql and a good grip on css, and it kind of defeats the purpose. In France we say, "the best tool is the one you use every day". If you are frustrated with Drupal, learn Django, and in the same time needed to master Drupal, you will have a skill to write your own Drupal and others CMS, maybe.

I've used both Drupal and Django to complete major projects. You can use Drupal as a framework too, so in my opinion the two are absolutely comparable.
Django has a way better database abstraction than Drupal, follows more modern programming paradigms like OOP, MVC etc, is more flexible, and Python is just straight up superior to PHP.
...but I still usually use Drupal if either will do. It just gets the job done with less time spent, and works and performs well. Django has nothing like Views, and Drupal's form api is just light years ahead of Django's. Creating multi step ajax forms can be done without ever touching the markup or writing a single line of javascript in Drupal, and presenting dynamic lists to the user can be achieved without even leaving your browser.
Drupal has a much greater deployment rate than Django, not just because of PHP's popularity, but because it actually does some things really well.

"Append" and "extend" conceptually only apply to ordered types. | 1 | 6 | 0 | Is there an article or forum discussion or something somewhere that explains why lists use append/extend but sets and dicts use add/update.
I frequently find myself converting lists into sets and this difference makes that quite tedious so for my personal sanity I'd like to know what the rationalization is.
The need to convert between these occurs regularly as we iterate on development. Over time as the structure of the program morphs various structures gain and lose requirements like ordering and duplicates.
For example something that starts out as an unordered bunch of stuff in a list might pick up the the requirement that there be no duplicates and so need to be converted to a set.
All such changes require finding and changing all places where the relevant structure is added/appended and extended/updated.
So I'm curious to see the original discussion that led to this language choice, unfortunately I've had no luck googling for it. | add append update and extend in python | 0.197375 | 0 | 0 | 9,659 |

Do you manipulate Form and Field objects prior to assigning them values? Do you need to frequently iterate over all the given Fields? Do you need Form once it's been submitted? Etc.
I'd suggest writing some/all of the code that uses Form and figure out how you want to interact with Form data, and what your ideal interface would look like. | 1 | 1 | 0 | Forms have Fields, Fields have a value. However, they only get a value after the form has been submitted.
How should I store this value? Should I give every field a value attribute, field.value,
leave it as None prior to posting, and fill it in afterwords?
Omit it completely, and dynamically add it?
Store it on the form instead, like form.data['field'].
Create a a wrapper class FieldWithData to avoid any inconsistent states (if you have an object of this type, you know it has data) and allows me to set the data in the initializer rather than accessing attributes directly (although I guess this isn't so different from using a setter)
How should I provide access to the field data through the Form object? Options:
form.fields['name'].value (how it's presently being stored internally)
form.data['field'] (create a proxy "data" class that retrieves the real data off the field, or re-arrange the internals to actually store the data like this)
form.field.value - looks fairly nice, but then I'd have two references to the same field, one as form.field and one as form.fields['field'] which I need internally so that I can iterate over them

If they're not, you can simply replace the hostname part of the URL with their IP address, per @Greg's answer.
If they are, however, you have to ensure that the correct Host: header is sent as part of the HTTP request. Without that, a virtual hosting web server won't know which site's content to give you. Refer to your HTTP client API (Curl?) to see if you can add or change default request headers. | 2 | 2 | 0 | I want my Python script to access a URL through an IP specified in the script instead of through the default DNS for the domain.

That said, it isn't a good idea to use IP numbers instead of DNS entries. IPs change a lot more often than DNS entries, meaning your script has a greater chance of breaking if you hard-code the address instead of letting it resolve normally. | 2 | 2 | 0 | I want my Python script to access a URL through an IP specified in the script instead of through the default DNS for the domain.
