javascript - Web Application - Dynamic Image Rendering -

-

When it comes to web applications, I am a complete Noah I created a network visualization toolkit based on Google App Engine I am doing I have implemented the Spanning Tree Protocol as a sample. This is what it does:

  1. Take the network topology as an input from the client
  2. Generate a network graph based on 1, and the image to the customer
  3. Generate trees spanning the MST protocol
  4. presenting the image of a tree spreading to the user

    I can go to the demo to see my professor to stay away from javascript Have been instructed by. If you see, the application runs properly.

    Here's the problem:

    1. The MST protocol is a step-by-step algorithm. Currently this application runs the entire algorithm in the backend and gives the final result.
    2. What is my profile? I want to do this, add a 'step by step' button. If the user clicks on that button, then the entire MST protocol is run one step at a time so that the user can work on MST Could imagine the actual simulation of

      I do not know at all how to do this. As I said, web development is not really my feature, if my explanation of the problem is not enough, please tell me I will try to explain it properly. And once visited the website it will tell you what the application does.

      1 Edit: I had to do this work. Those who are thinking, I create a hidden variable 'iterator' which I exchange between HTML and the Python backend so that step number is detected in every click of step by step button. Could. In the server side, I am creating a simple data structure to store all the examples generated by my algorithm. This combination with the Iterator, the image is provided. The links posted above now reflect those changes.

      Generate a series of images for each step, then create a GUI that clicks on the previous / next button Allows to change the displayed image. It is without any javascript, just using HTML + CSS.

python - Writing Greek in matplotlib labels, titles -

Image
I'm trying to write some text for labels, shape titles etc. with my plots, but no benefit till now Has not happened . I do not want to print specific characters (I know how to use special characters), I want to write the entire text in Greek (maybe Unicode and text ' ?). , suggesting that I would like to mention that for some reason I can not get matplotlib to cooperate with Tex (using IPython notebook from Anaconda in Ubuntu 14.10) so that there really is an option Will not be the first. I tried loading the Arial font and it loads successfully but again I get square blocks instead of characters. I import matplotlib.font_manager FM PROP = FM Font Properties (fname = '/ usr / share / fonts / truetype / msttcorefonts / Arial.ttf') And then to display the string I u'Î? ? I ?? Î¿Ï ??

c# - LINQ to Entities does not recognize the method 'Int32 IndexOf(System.String, System.StringComparison)' method -

I have performed a linq query using Entityframework as below GroupMaster getGroup = Null; GetGroup = DataContext.Groups.FirstOrDefault (item = & gt; keyword.IndexOf (item.Keywords, StringComparison.OrdinalIgnoreCase)> = 0 & amp; amp; item.ISNAmd) I found an exception like the method when executing it LINQ units do not recognize the 'Inter 32 index of (system string, system. String compromise)' method, and This method can not be translated to Store expression. Includes () method is sensitive by default, then I need to convert to minimize. Is there any method in which a string match match is examined and whether there is any method to solve the index question of the method? You actually have four options Databases globally Change the colon of it can be done in many ways, a simple Google search should reveal to them. Change the mix of individual tables or columns. Use a stored procedure and specify the call statement on your query Perform...

Pygame memory leak with transform.flip -

-
Today I came across an interesting issue which, by writing a small side scroller, instead of a sprite sheet, I was planning to use because I lacked a good "packer" for making phantom sheets (and honestly with patience and passion as it is only a test project). Anyway, I showed the animation running on the right of 8 PNG (with transparency). I considered it a good idea to prepare the flipped images to run on the left in the consultant, and the frame is not framed when the game is running (Flip actually consumes a lot of CPU like I Was measured). > To get access to the loop, I get the memory leak self.move_l = [# 8 PNG images with transparency to the right] For the self in IMG. Move_l: self.move_r.append (pygame.transform.flip (img, true, false) error traceback: traceback (most recent Call final): The file "D: \ Python 34 \ _Projects \ efg \ efg.py", in line 196, in the & lt; module & gt; main = master program ((1024, 680)) "D: \ Python ...
