  • Putting newline in matplotlib label with TeX in Python?

    - by user248237
    How can I add a newline to a plot's label (e.g. xlabel or ylabel) in Matplotlib? For example, plt.bar([1, 2], [4, 5]) plt.xlabel("My x label") plt.ylabel(r"My long label with $\Sigma_{C}$ math \n continues here") Ideally i'd like the y-labeled to be centered too. Is there a way to do this? It's important that the label have both tex (enclosed in '$') and the newline. thanks.

  • Can a CSS class inherit one or more other classes?

    - by Joel Martinez
    I feel dumb for having been a web programmer for so long and not knowing the answer to this question, I actually hope it's possible and I just didn't know about rather than what I think is the answer (which is that it's not possible). My question is whether it is possible to make a CSS class that "inherits" from another CSS class (or more than one). For example, say we had: .something { display:inline } .else { background:red } What I'd like to do is something like this: .composite { .something; .else } where the ".composite" class would both display inline and have a red background

  • How to handle main option with Getopt

    - by Jérôme
    I want to handle a feature which seems to me almost natural with programs, and I don't know how to handle it with Getopt perl package (no matter Std ot Long). I would like something like: ./perlscript <main option> [some options like -h or --output-file some_name] Options will be handled with - or --, but I want to be able to let the user give me the main and needed option without dashes. Is Getopt able to do that, or do I have to handle it by hand?

  • How can I associate .sh files with Cygwin?

    - by Jerph
    I'd like to run a long rsync command in Cygwin by double clicking on a .sh file in Windows. It must start in the file's containing directory (e.g. /cygdrive/c/scripts/) so that relative paths work. Anyone gotten this to work? Note: I've just found chere, a Cygwin package that manages Windows context menus (Bash Prompt Here). It might have some clues.

  • Is it safe to make GL calls with multiple threads?

    - by user146780
    I was wondering if it was safe to make GL calls with multiple threads. Basically I'm using a GLUtesselator and was wondering if I could divide the objects to draw into 4 and assign a thread to each one. I'm just wondering if this would cause trouble since the tesselator uses callback functions. Can 2 threads run the same callback at the same time as long as that callback does not access ant global variables? Are there also other ways I could optimize OpenGL drawing using multithreading? Thanks

  • Good or Bad experiences with CryptoLicensing?

    - by dr. evil
    I'm planning to buy CryptoLicensing but before buying it I'd like to get some feedbacks if anyone tried it before. Also it'd be interesting if anyone cracked it or spotted an easy hack against it. I've seen some other SO questions regarding the choosing a .NET licensing component but if you currently happy with another component it'd be nice to hear your experience. It's just quite hard to nail this without going through a long trial.

  • Resolving C++ Name Collision

    - by jnm2
    InitializeQTML is a function in QTML.h. I'm writing a wrapper and I would like to use the name InitializeQTML for the wrapper function: #include <QTML.h> public class QuickTime { public: static void InitializeQTML(InitializationFlags flag) { InitializeQTML((long)flag)); }; }; How can I reference the original InitializeQTML function from inside the wrapper function and avoid the name collision without renaming the wrapper?

  • Visual Studio 2010 - Is it slow for anyone else?

    - by AngryHacker
    I've read a lot of stuff about VS2010 being much more performant than VS2008. When I've finally installed it, I found that it, in fact, is much slower (save for the Add References dialog). For instance, Silverlight projects take twice as long to load, the startup of the IDE itself is much slower, etc... Am I missing something here or is it like this for everyone?

  • instantiate object with reflection using constructor arguments

    - by justin
    I'm trying to figure out how to instantiate a case class object with reflection. Is there any support for this? The closest I've come is looking at scala.reflect.Invocation, but this seems more for executing methods that are a part of an object. case class MyClass(id:Long, name:String) def instantiate[T](className:String)(args:Any*) : T = { //your code here } Is close to the API I'm looking for. Any help would be appreciated.

  • Leading a Developer Meeting?

    - by hypoxide
    I've recently inherited responsibility for organizing and running the hour long monthly developer meetings at my office. I've only been out of college for 2 years so I'm kind of intimidated by holding the reins for this type of thing. The group is composed of about 20 developers, more than half of which are significantly more senior than I am. I need some tips on how to make this meeting valuable for everybody, as well as any possible advice/consolation/condolences you can give me.

  • Automatically download files in Ruby

    - by Obinna
    I'm trying to write a ruby script which automatically downloads some files from some server ever 30-45 minutes (to prevent overload) as long as my computer is turned on. It's possible that my computer might be turned off at some point, but the download should resume (probably re-download the current file). I already have the file list but I can't figure out how to make such a script to run autonomously. What are some ways I can do this?

  • Making a python script run at a set rate.

    - by Matt1024
    How can I make a python loop run at a set rate regardless of how long it takes to execute commands in the loop (providing the commands take less time to run than the loop is allowed)? How can I make this run every 0.25 seconds, for example? while True: print("OK")

    I have panel that I have customized. I use it to display text. But sometimes that text is too long and wraps to the next line. Is there some way I can auto resize the panel to show all the text? I am using C# and Visual Studio 2008 and the compact framework.

  • Randomised objects are assigning themselves to more than one array location

    - by Thaddeus Aid
    this.size = 9; this.populationSize = 10; Random rand = new Random(); Integer[][] easy1 = new Integer[size][size]; easy1 = this.initializeEasy1(easy1); this.sudokuArray = new Sudoku[this.populationSize]; for (int i = 0; i < this.sudokuArray.length; i++){ long seed = rand.nextLong(); System.out.println("" + seed); this.sudokuArray[i] = new Sudoku(easy1, this.size, seed); } I am building an evolutionary sudoku solver and I am having a problem where the last Sudoku object is overwriting all the other objects in the array. Where in the code did I mess up? /edit here is the constructor of the class public Sudoku(Integer[][] givensGrid, int s, long seed){ this.size = s; this.givens = givensGrid; this.grid = this.givens.clone(); Random rand = new Random(seed); System.out.println("Random " + rand.nextInt()); // step though each row of the grid for (int i = 0; i < size; i++){ ArrayList<Integer> numbers = new ArrayList<Integer>(); numbers = this.makeNumbers(numbers); // step through each column to find the givens and remove from numbers for (int j = 0; j < size; j++){ if (this.grid[i][j] != 0){ numbers.remove(this.grid[i][j]); } } // go back through the row and assign the numbers randomly for (int j = 0; j < size; j++){ if (this.grid[i][j] == 0){ int r = rand.nextInt(numbers.size()); this.grid[i][j] = numbers.get(r); numbers.remove(r); } } } System.out.println("============="); System.out.println(this.toString()); }

  • Save all file names in a directory to a vector

    - by Bobby
    I need to save all ".xml" file names in a directory to a vector. To make a long story short, I cannot use the dirent API. It seems as if C++ does not have any concept of "directories". Once I have the filenames in a vector, I can iterate through and "fopen" these files. Is there an easy way to get these filenames at runtime?
