• What resources do you recommend for learning more about TCP/IP, networking, and related areas?

  - by mkelley33

  As a relatively-new Python programmer, I'm finding more and more that networking as it relates to the web and web development is becoming increasingly important to understand. When I was an active C# ASP.NET programmer making smaller websites with less responsibility this knowledge seemed less important, since there was often a "networking" guy performing any tasks beyond acquiring a domain name for a client. Which books, websites, presentations, articles, or other resources would you recommend so that I best understand what's happening between the time a user types a URL and receives the rendered HTML? Thanks!

• Test case as a function or test case as a class

  - by GodMan

  I am having a design problem in test automation:- Requirements - Need to test different servers (using unix console and not GUI) through automation framework. Tests which I'm going to run - Unit, System, Integration Question: While designing a test case, I am thinking that a Test Case should be a part of a test suite (test suite is a class), just as we have in Python's pyunit framework. But, should we keep test cases as functions for a scalable automation framework or should be keep test cases as separate classes(each having their own setup, run and teardown methods) ? From automation perspective, Is the idea of having a test case as a class more scalable, maintainable or as a function?

• Facing problem with "gtk.RESPONSE_OK" in the simple-player quickly tutorial

  - by sumit_gt

  I am fairly new to both quickly and Python. I am facing several problems while learning to use quickly from the following tutorial on the Ubuntu developers site: http://developer.ubuntu.com/resources/app-developer-cookbook/multimedia/creating-a-simple-media-player/ The following error I'm unable to understand: Traceback (most recent call last): File "/home/sumit/Sumit/simple-player/simple_player/SimplePlayerWindow.py", line 36, in on_openbutton_clicked if response==gtk.RESPONSE_OK: NameError: global name 'gtk' is not defined I realize that I am supposed to import something, so I tried to add import gtk which it didn't work and it gave the following error: from gtk import _gtk /usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:40: Warning: g_type_get_qdata: assertion `node != NULL' failed from gtk import _gtk I have followed every step of the tutorials so far. But there is no mention of any other imports other that "prompts" and "os". Please help. Contribution of Agmenor, facing the same problem: I also tried to replace the text if response == gtk.RESPONSE_OK: by if response == Gtk.RESPONSE_OK: (notice the capital G). This gives another error: AttributeError: 'gi.repository.Gtk' object has no attribute 'RESPONSE_OK'

• Noob-Friendly Guides to WSGI?

  - by Johnny McKenzie

  world! I have recently been delving into server-side code web development with python, and I have hit a brick wall; you see, I know little about server side code and HTTP (other than the v. basics with php shudder), and all of the docs for wsgi that I have found seem to be for people already well established in the field. Are there any n00b happy guides for server-side scripting (the theory of), or on wsgi out there. Http would be helpful, video tuts are also greatly appreciated. Thanks in advance.

• Programmers that need a lot of "Outside Help" - Is this bad?

  - by Zanneth

  Does anyone else think it's kind of tacky or poor practice when programmers use an unusual amount of libraries/frameworks to accomplish certain tasks? I'm working with someone on a relatively simple programming project involving geolocation queries. The guy seems like an amateur to me. For the server software, this guy used Python, Django, and a bunch of other crazy libraries ("PostGIS + gdal, geoip, and a few other spatial libraries" he writes) to create it. He wrote the entire program in one method (in views.py, nonetheless facepalm), and it's almost unreadable. Is this bad? Does anyone else think that this is really tacky and amateurish? Am I the only minimalist out there these days?

• What languages are most commonly used in medical research?

  - by Chris Taylor

  For someone about to go into a career in medical research, what language would be the most useful to learn? From my limited experience (I have been a researcher in mathematics and in finance) I have been able to recommend looking at R (for statistics) Matlab (for general numeric processing) and Python (for general purpose programming with statistics/numerics as an add-on) but I don't know which of those (if any) are in common use -- or if there are other, more specialized languages that are used. To be clear, I'm not talking about a professional programmer working in a medical setting. I am talking about a medical or genetics researcher who uses programming to analyse data, or generally to help get their work done.

• Pygame set_colorkey transparency issues

  - by Nathan Chowning

  I'm having a strange issue that I cannot seem to remedy. I am doing some prototyping with Pygame on a desktop running windows and a laptop running OS X. Both are running python v2.7.3 (installed via homebrew for the Macbook) and pygame v1.9.1. For transparency, I have been using set_colorkey with a transparency color of (255, 0, 255). Here is the applicable code: transColor = pygame.Color(255, 0, 255) image = pygame.image.load(playerPath + "idle.png").convert() image.set_colorkey(transColor) This works flawlessly on my windows machine. On my laptop, it does not work. It just shows the hideous magenta color. Here's the strange part. If I change the transColor to (0, 0, 0), all black pixels in my images are transparent. Has anyone run into this issue before?

• High Usage of RAM by wxPython's GUI and need some advice to reduce it

  - by user67024

  I've recently developed a GUI in wxPython for windows platform. It contains a five tabs, 4 of them are just richTextCtrl boxes and the other one has controls for uploading files, buttons, textctrls, a slider etc.. As I was new to GUI development in Python, I used wxFormBuilder to generate some of the code using a good amount of sizers. So, now the problem is that the GUI starts off with a initial memory of around 40MB which is too much for such a simple application (Or so I think) . Also, when the functions handling the functions use huge lists as the program is for debugging large data logs and identifying the problems in'em implying that I can't afford memory for GUI. So, how can I reduce that start working memory size? Is it a general issue in wxPython? And currently trying use profilers but not sure if it's going to help.

• Good library for search text tokenization

  - by Chris Dutrow

  Looking to tokenize some text in the same or similar way in which a search engine would do it. The reason we are doing this is so that we can run some statistical analysis on the tokens. The language we are using is python, so would prefer a library in that language, but could probably set something up to use another language if necessary. Example Original token: We have some great burritos! More simplified: (remove plurals and punctuation) We have some great burrito Even more simplified: (remove superfluous words) great burrito Best: (recognize positive and negative meaning): burrito -positive-

• How to use OO for data analysis? [closed]

  - by Konsta

  In which ways could object-orientation (OO) make my data analysis more efficient and let me reuse more of my code? The data analysis can be broken up into get data (from db or csv or similar) transform data (filter, group/pivot, ...) display/plot (graph timeseries, create tables, etc.) I mostly use Python and its Pandas and Matplotlib packages for this besides some DB connectivity (SQL). Almost all of my code is a functional/procedural mix. While I have started to create a data object for a certain collection of time series, I wonder if there are OO design patterns/approaches for other parts of the process that might increase efficiency?

• Open source projects, how to choose?!

  - by Dhaivat Pandya

  I would like to join an open source project since I think I am good enough at programming to progress onto reading others code and to modify it. But the proble mis, how would I choose an open source project to work on? I know many languages and chief ones that I am good are python, C++ (not really very good at C, the lack of object orientation is difficult for me) and Java. For c++, I am proficient wit Qt. I would like to start with something that isn't huge, and hasn't reached a phase where the bugs are so complicated it would take me a month to understand what affects the bug. Any suggestions? At the current time, I don't use any libraries in either of the mentioned libraries that I would need to modify (AFAIK).

• How to set-up a simple subversion workflow

  - by Milen Bilyanov

  I am trying to set-up a simple SVN workflow at home. I am new to subversion (and programming) so I have been reading the official PDF documentations but still not sure about how to set-up my repository. I am working mainly with python, bash and rsl (Renderman Shading Language) So I already have a /dev structure on my disk as this: http://imageshack.us/f/708/devstructure.png/ And I have a /site structure that links to my /dev folder: http://imageshack.us/f/651/sitestructure.png/ So obviously starting to use SVN will change this approach that I already have in place. The question is when I am setting-up my SVN repository for the work I do in my /dev folder: Will I set-up a separate repository for each different programming platform? and Where exactly I should be placing my repository? Thanks.

• All-around programming language for use on desktop and mobile devices

  - by mdm414 ZX

  Given that I am a PHP programmer and open-source is a must, what would be the best and practical programming language to use for all of the following: A desktop/cross-platform application. I've read that with HTML5, creating offline apps are possible? A web application. Android and iPhone/iPad apps. I am leaning towards using Python but I am not sure if it is possible to use it alone for all of them. There are other languages that I am also looking at like Ruby, Scala and Java. Kindly share your thoughts and experiences on this one. Thanks :-)

• Page for Page Redirect in Google App Engine

  - by clifgray

  I have recently changed domain name for a webapp I run on Google App Engine and I am wondering if there is a simple way to do a page for page redirect from my old website to the new domain. Everything code wise is staying exactly the same but I just want it to go to the new domain. I am using python and the webapp2 framework for the webapp. I know I could go through and for every single handler do: webapp2.redirect('the specific url', permanent=True) But I am hoping for a simpler solution.

• Which is easier to learn, Zend Framework, CakePHP or CodeIgniter?

  - by Kwame Boame

  I am new to programming but I know HTML, CSS and Jquery. I am a web designer but want to expand my skill to application development with frameworks. Specifically, PHP frameworks. I want to know which of the frameworks mentioned in the question is difficult to master. Also, my friend wants me to learn Ruby on Rails/ Python instead of PHP. What's your best advice for a newbie programmer who is looking to build online software/apps in the near future; say, after 3 months/6 months or a year of study and practice?

• Issue with dynamic Quicklist in Unity

  - by costales

  I would like to add a Quicklist to Gufw app, but it isn't working. The code is here (you can install reading the INSTALL file): http://bazaar.launchpad.net/~gufw-developers/gui-ufw/testing/files/3 I added lines 52-54 to the view (a simple example) from the official API web: http://bazaar.launchpad.net/~gufw-developers/gui-ufw/testing/view/head:/gufw/view/gufw.py https://wiki.ubuntu.com/Unity/LauncherAPI self.launcher = Unity.LauncherEntry.get_for_desktop_id ("gufw.desktop") self.launcher.set_property("progress", 0.42) self.launcher.set_property("progress_visible", True) But nothing happen. But if I run this file with Gufw running: http://bazaar.launchpad.net/~gufw-developers/gui-ufw/testing/view/head:/gufw/test_launcher.py $ python test_launcher.py The progress bar appears! :/ I don't know what am I missing? :P Any idea? Thanks in advance! The environment is Ubuntu 13.04.

• What encryption algorithm/package should I use in a betting game?

  - by user299648

  I have a betting type site where I publish a number (between 0-100) that is encrypted. Then after a period of time, I would review what the number is and prove it with a key to decrypt the encrypted number to prove that I'm not cheating. I also want it to be easily verifiable by an average user. What encryption algorithm/technique/package should I use? I'm no expert on cryptography. There seems to be so many options out there and I'm not sure what to use. python friendly is a plus.

• Is there a name for this functional programming construct/pattern?

  - by dietbuddha

  I wrote a function and I'd like to find out if it is an implementation of some functional programming pattern or construct. I'd like to find out the name of this pattern or construct (if it exists)? I have a function which takes a list of functions and does this to them: wrap(fn1, fn2, fn3, fn4) # returns partial(fn4, partial(fn3, partial(fn2, fn1))) There are strong similarities to compose, reduce, and other fp metaprogramming constructs, since the functions are being arranged together and returned as one function. It also has strong similarities to decorators and Python context managers since it provides a way to encapsulate pre and post execution behaviors in one function. Which was the impetus for writing this function. I wanted the ability that context managers provide, but I wanted to be able to have it defined in one function, and to be able to layer function after function on top.

• Language Design: Are languages like phyton and coffescript really more comprehendable?

  - by kittensatplay

  the "Verbally Readable !== Quicker Comprehension" arguement on http://ryanflorence.com/2011/case-against-coffeescript/ is really potent and interesting. i and im sure other would be very interested in evidence arguing against this. there's clear evidence for this and i believe it. ppl naturally think in images, not words, so we should be designing languages dissimilar to human language like english, french, whatever. being "readable" is quicker comprehension. most articles on wikipedia are not readable as they are long, boring, dry, sluggish, very very wordy, and because wikipedia documents a ton of info, is not especially helpful when compared to much more helpful sites with more practical, useful, and relevant info. but languages like phyton and coffescript are "verbally readable" in that they are closer to the english language syntax, and programming firstly and mainly in python, im not so sure this is really a good thing. the second interesting argument is that coffeescript is an intermediator so thereby another step between to ends, which may increase chances of bugs. while coffeescript has other practical benefits, this question is focused specifically on evidence showing support for the counter-case of language "readability"

  I downloaded Indicator-Char and unzipped the files. I added the characters there I wanted perfectly. When I run the python script it loads the daemon and I can see this characters. But the problem is that when I click on them, not copied anything to the clipboard. I see the code where is the copy function, is the following. def on_char_click(self, widget, char): cb = gtk.Clipboard(selection="PRIMARY") cb.set_text(char) Is a syntax problem? There is a problem on my system?

• How to get audio spectrum analysis?

  - by Mrwolfy

  I need to find or create a tool that analyzes the audio spectrum of a sound file (like a .wav or .mp3). I need to output the "volume" or power of x number of frequency bands and output the data as text. This will be used to produce a visualization, a graphic equalizer like you'd see on a stereo. I am currently looking at python to do it. My question is are there some tools out there that would do this (signal processing), like math works or others? I don't have any experience with them so any advice would be appreciated.

• Any frameworks or library allow me to run large amount of concurrent jobs schedully?

  - by Yoga

  Are there any high level programming frameworks that allow me to run large amount of concurrent jobs schedully? e.g. I have 100K of urls need to check their uptime every 5 minutes Definitely I can write a program to handle this, but then I need to handle concurrency, queuing, error handling, system throttling, job distribution etc. Will there be a framework that I only focus on a particular job (i.e. the ping task) and the system will take care of the scaling and error handling for me? I am open to any language.

• Error installing gPodder

  - by Ron Webb

  A few weeks ago (newbie alert!) I started using XUbuntu 12.04 with Xfce 4.8. I'm trying to install gPodder Podcast Client (see https://launchpad.net/~thp/+archive/gpodder). I've added the PPA via terminal commands as instructed. When I click the Install button in the Ubuntu Software Centre I get the following error: Package dependencies cannot be resolved This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time. Details: The following packages have unmet dependencies: gpodder: Depends: python-webkit but it is not going to be installed What do I need to do? Just to make thing more complicated -- I'm not sure, but before I found the launchpad.net link, I think I may have tried to install gPodder from the default Ubuntu repositories (also unsuccessfully). There may be remnants of the previous attempt still installed, which may be blocking the new install. Where/how can I find them?

• Asynchronously returning a hierarchal data using .NET TPL... what should my return object "look" like?

  - by makerofthings7

  I want to use the .NET TPL to asynchronously do a DIR /S and search each subdirectory on a hard drive, and want to search for a word in each file... what should my API look like? In this scenario I know that each sub directory will have 0..10000 files or 0...10000 directories. I know the tree is unbalanced and want to return data (in relation to its position in the hierarchy) as soon as it's available. I am interested in getting data as quickly as possible, but also want to update that result if "better" data is found (better means closer to the root of c:) I may also be interested in finding all matches in relation to its position in the hierarchy. (akin to a report) Question: How should I return data to my caller? My first guess is that I think I need a shared object that will maintain the current "status" of the traversal (started | notstarted | complete ) , and might base it on the System.Collections.Concurrent. Another idea that I'm considering is the consumer/producer pattern (which ConcurrentCollections can handle) however I'm not sure what the objects "look" like. Optional Logical Constraint: The API doesn't have to address this, but in my "real world" design, if a directory has files, then only one file will ever contain the word I'm looking for.  If someone were to literally do a DIR /S as described above then they would need to account for more than one matching file per subdirectory. More information : I'm using Azure Tables to store a hierarchy of data using these TPL extension methods. A "node" is a table. Not only does each node in the hierarchy have a relation to any number of nodes, but it's possible for each node to have a reciprocal link back to any other node. This may have issues with recursion but I'm addressing that with a shared object in my recursion loop. Note that each "node" also has the ability to store local data unique to that node. It is this information that I'm searching for. In other words, I'm searching for a specific fixed RowKey in a hierarchy of nodes. When I search for the fixed RowKey in the hierarchy I'm interested in getting the results FAST (first node found) but prefer data that is "closer" to the starting point of the hierarchy. Since many nodes may have the particular RowKey I'm interested in, sometimes I may want to get a report of ALL the nodes that contain this RowKey.
