    - by user324333
    Hey Guys, This seems like a basic problem with an easy answer but I simply cannot figure it out no matter how much I try. I am trying to create a line graph based on two lists. For my x-axis, I want my list to be a set of strings. x_axis_list = ["Jan-06","Jul-06","Jan-07","Jul-07","Jan-08"] y_axis_list = [5,7,6,8,9] Any suggestions on how to best graph these items?

  • Big O, how do you calculate/approximate it?

    - by Sven
    Most people with a degree in CS will certainly know what Big O stands for. It helps us to measure how (in)efficient an algorithm really is and if you know in what category the problem you are trying to solve lays in you can figure out if it is still possible to squeeze out that little extra performance.* But I'm curious, how do you calculate or approximate the complexity of your algorithms? *: but as they say, don't overdo it, premature optimization is the root of all evil, and optimization without a justified cause should deserve that name as well.

    - by Rangi Robinson
    Hello, I'd like to rewrite: www.example.com/file.html?username=john&number=1234 To: www.example.com/users/john But I can't figure out how to extract the "username" value from the query string.

  • PDB: exception when in console - full stack trace

    - by EoghanM
    When at the pdb console, entering a statement which causes an exception results in just a single line stack trace, e.g. (Pdb) someFunc() *** TypeError: __init__() takes exactly 2 arguments (1 given) However I'd like to figure out where exactly in someFunc the error originates. i.e. in this case, which class __init__ is attached to. Is there a way to get a full stack trace in Pdb?

  • Writing a DBMS in Python

    - by Matt Luongo
    Hey guys, I'm working on a basic DBMS as a pet project and planning to prototype in Python. I figure there's a reason there are only a few Python databases, and my gut agrees that my favorite language will be too slow to act as an honest performing database, but I'm looking forward to using it to learn what I need quickly. Would someone please contradict me? Is Python as ill-suited right now for this sort of thing as I think?

  • How could I make geometry advanced operations on bezier paths?

    - by yizzreel
    I have a library that draws regular bezier path figures (complex paths formed of a lot of bezier points), using midpoint approximation. I can draw them without problem, but I need to add support for advanced geometry operations: Nearest point of a curve, intersection, figure contains point, and more importantly, path combinations: difference, intersection, exclusive-or, union, ... Is there any good source to get all this? Thanks

  • What are the differences and similarities between the .NET languages?

    - by froadie
    I'm trying to figure out how much overlap there is between the different languages of the .NET framework, and what the real differences are. Is there an overlap of libraries/methods/functions...? If I'm googling a question for, say, VB .NET, and C# answers come up, what can I take from the C#-relevant info and what differences/incompatibilities should I look out for?

    Given a series of points, how could I calculate the vector for that line 5 pixels away? Ex: Given: \ \ \ How could I find the vector for \ \ \ \ \ \ The ones on the right.

    I have a simple Cocoa app using a NSWindowController subclass.

I must be missing something obvious, but for the life of me I can't figure out what it is.

  • Extjs Form Action Submit - Custom override?

    - by Scott
    Looking at the source code of Action.Submit, I'm trying to figure out where ext is appending the form's fields to the parameters. Instead of sending each field as a separate parameter, I want to send something like: formObj:{field1:value, field2:value} Currently, each of those values are simply added to the parameter list along with any custom/baseParams. Where are these formfields being added so that I can change this behaviour? Thanks.

  • Ruby on Rails testing: How can I test or at the very least see a form_for's error_messages_for?

    - by williamjones
    I'm working on creating a tests, and I can't figure out why the creation of a model from a form_for is failing in the test but works in real browsers. Is there a straightforward way for me to see what the problems are in the model creation? Even better would be, is there a straightforward way for me to test the error outputs that I access via error_messages_for? In that case, I'd like to also add in tests that make sure that malformed forms are outputting the correct errors.

  • Modifying vertex properties in a Boost::Graph

    - by Paul Nathan
    I am trying to figure out how to use boost::graph to store some information. However, there is information I want tied to each vertex. Staring at the documentation for the library reveals either(a)badly written documentation, or (b), I'm obviously not as good at C++ as I thought. Pick two. I am looking for either a tutorial on assigning properties, or a simple example use.
