• Project Euler 19: (Iron)Python

  - by Ben Griswold

  In my attempt to learn (Iron)Python out in the open, here’s my solution for Project Euler Problem 19.  As always, any feedback is welcome. # Euler 19 # http://projecteuler.net/index.php?section=problems&id=19 # You are given the following information, but you may # prefer to do some research for yourself. # # - 1 Jan 1900 was a Monday. # - Thirty days has September, # April, June and November. # All the rest have thirty-one, # Saving February alone, # Which has twenty-eight, rain or shine. # And on leap years, twenty-nine. # - A leap year occurs on any year evenly divisible by 4, # but not on a century unless it is divisible by 400. # # How many Sundays fell on the first of the month during # the twentieth century (1 Jan 1901 to 31 Dec 2000)? import time start = time.time() import datetime sundays = 0 for y in range(1901,2001): for m in range(1,13): # monday == 0, sunday == 6 if datetime.datetime(y,m,1).weekday() == 6: sundays += 1 print sundays print "Elapsed Time:", (time.time() - start) * 1000, "millisecs" a=raw_input('Press return to continue')

• Matching the superclass's constructor's parameter list, is treating a null default value as a non-null value within a constructor a violation of LSP?

  - by Panzercrisis

  I kind of ran into this when messing around with FlashPunk, and I'm going to use it as an example. Essentially the main sprite class is pretty much class Entity. Entity's constructor has four parameters, each with a default value. One of them is graphic, whose default value is null. Entity is designed to be inherited from, with many such subclasses providing their own graphic within their own internal workings. Normally these subclasses would not have graphic in their constructor's parameter lists, but would simply pick something internally and go with it. However I was looking into possibly still adhering to the Liskov Substitution Principal. Which led me to the following example: package com.blank.graphics { import net.flashpunk.*; import net.flashpunk.graphics.Image; public class SpaceGraphic extends Entity { [Embed(source = "../../../../../../assets/spaces/blank.png")] private const BLANK_SPACE:Class; public function SpaceGraphic(x:Number = 0, y:Number = 0, graphic:Graphic = null, mask:Mask = null) { super(x, y, graphic, mask); if (!graphic) { this.graphic = new Image(BLANK_SPACE); } } } } Alright, so now there's a parameter list in the constructor that perfectly matches the one in the super class's constructor. But if the default value for graphic is used, it'll exhibit two different behaviors, depending on whether you're using the subclass or the superclass. In the superclass, there won't be a graphic, but in the subclass, it'll choose the default graphic. Is this a violation of the Liskov Substitution Principal? Does the fact that subclasses are almost intended to use different parameter lists have any bearing on this? Would minimizing the parameter list violate it in a case like this? Thanks.

• How do "custom software companies" deal with technical debt?

  - by andy

  What are "custom software companies"? By "custom software companies" I mean companies that make their money primarily from building custom, one off, bits of software. Example are agencies or middle-ware companies, or contractors/consultants like Redify. What's the opposite of "custom software companies"? The oposite of the above business model are companies that focus on long term products, whether they be deployable desktop/mobile apps, or SaaS software. A sure fire way to build up technical debt: I work for a company that attempts to focus on a suite of SaaS products. However, due to certain constraints we sometimes end up bending to the will of certain clients and we end building bits of custom software that can only be used for that client. This is a sure fire way to incur technical debt. Now we have a bit of software to maintain that adds nothing to our core product. If custom work is a sure fire way to build technical debt, how do agencies handle it? So that got me thinking. Companies who don't have a core product as the center of their business model, well they're always doing custom software work. How do they cope with the notion of technical debt? How does it not drive them into technical bankruptcy?

• Is QtQuick.Controls available on Ubuntu 13.10

• Using 2D sprites and 3D models together

  - by Sweta Dwivedi

  I have gone through a few posts that talks about changing the GraphicsDevice.BlendState and GraphicsDevice.DepthStencilState (SpriteBatch & Render states). . however even after changing the states .. i cant see my 3D model on the screen.. I see the model for a second before i draw my video in the background. . Here is the code: case GameState.InGame: GraphicsDevice.Clear(Color.AliceBlue); spriteBatch.Begin(); if (player.State != MediaState.Stopped) { videoTexture = player.GetTexture(); } Rectangle screen = new Rectangle(GraphicsDevice.Viewport.X, GraphicsDevice.Viewport.Y, GraphicsDevice.Viewport.Width, GraphicsDevice.Viewport.Height); // Draw the video, if we have a texture to draw. if (videoTexture != null) { spriteBatch.Draw(videoTexture, screen, Color.White); if (Selected_underwater == true) { spriteBatch.DrawString(font, "MaxX , MaxY" + maxWidth + "," + maxHeight, new Vector2(400, 10), Color.Red); spriteBatch.Draw(kinectRGBVideo, new Rectangle(0, 0, 100, 100), Color.White); spriteBatch.Draw(butterfly, handPosition, Color.White); foreach (AnimatedSprite a in aSprites) { a.Draw(spriteBatch); } } if(Selected_planet == true) { spriteBatch.Draw(kinectRGBVideo, new Rectangle(0, 0, 100, 100), Color.White); spriteBatch.Draw(butterfly, handPosition, Color.White); spriteBatch.Draw(videoTexture,screen,Color.White); GraphicsDevice.BlendState = BlendState.Opaque; GraphicsDevice.DepthStencilState = DepthStencilState.Default; GraphicsDevice.SamplerStates[0] = SamplerState.LinearWrap; foreach (_3DModel m in Solar) { m.DrawModel(); } } spriteBatch.End(); break;

• E.T. Phone "Home" - Hey I've discovered a leak..!

  - by Martin Deh

  Being a member of the WebCenter ATEAM, we are often asked to performance tune a WebCenter custom portal application or a WebCenter Spaces deployment.  Most of the time, the process is pretty much the same.  For example, we often use tools like httpWatch and FireBug to monitor the application, and then perform load tests using JMeter or Selenium.  In addition, there are the fine tuning of the different performance based tuning parameters that are outlined in the documentation and by blogs that have been written by my fellow ATEAMers (click on the "performance" tag in this ATEAM blog).  While performing the load test where the outcome produces a significant reduction in the systems resources (memory), one of the causes that plays a role in memory "leakage" is due to the implementation of the navigation menu UI.  OOTB in both JDeveloper and WebCenter Spaces, there are sample (page) templates that include a "default" navigation menu.  In WebCenter Spaces, this is through the SpacesNavigationModel taskflow region, and in a custom portal (i.e. pageTemplate_globe.jspx) the menu UI is contructed using standard ADF components.  These sample menu UI's basically enable the underlying navigation model to visualize itself to some extent.  However, due to certain limitations of these sample menu implementations (i.e. deeper sub-level of navigations items, look-n-feel, .etc), many customers have developed their own custom navigation menus using a combination of HTML, CSS and JQuery.  While this is supported somewhat by the framework, it is important to know what are some of the best practices in ensuring that the navigation menu does not leak.  In addition, in this blog I will point out a leak (BUG) that is in the sample templates.  OK, E.T. the suspence is killing me, what is this leak? Note: for those who don't know, info on E.T. can be found here In both of the included templates, the example given for handling the navigation back to the "Home" page, will essentially provide a nice little memory leak every time the link is clicked. Let's take a look a simple example, which uses the default template in Spaces. The outlined section below is the "link", which is used to enable a user to navigation back quickly to the Group Space Home page. When you (mouse) hover over the link, the browser displays the target URL. From looking initially at the proposed URL, this is the intended destination.  Note: "home" in this case is the navigation model reference (id), that enables the display of the "pretty URL". Next, notice the current URL, which is displayed in the browser.  Remember, that PortalSiteHome = home.  The other highlighted item adf.ctrl-state, is very important to the framework.  This item is basically a persistent query parameter, which is used by the (ADF) framework to managing the current session and page instance.  Without this parameter present, among other things, the browser back-button navigation will fail.  In this example, the value for this parameter is currently 95K25i7dd_4.  Next, through the navigation menu item, I will click on the Page2 link. Inspecting the URL again, I can see that it reports that indeed the navigation is successful and the adf.ctrl-state is also in the URL.  For those that are wondering why the URL displays Page3.jspx, instead of Page2.jspx. Basically the (file) naming convention for pages created ar runtime in Spaces start at Page1, and then increment as you create additional pages.  The name of the actual link (i.e. Page2) is the page "title" attribute.  So the moral of the story is, unlike design time created pages, run time created pages the name of the file will 99% never match the name that appears in the link. Next, is to click on the quick link for navigating back to the Home page. Quick investigation yields that the navigation was indeed successful.  In the browser's URL there is a home (pretty URL) reference, and there is also a reference to the adf.ctrl-state parameter.  So what's the issue?  Can you remember what the value was for the adf.ctrl-state?  The current value is 3D95k25i7dd_149.  However, the previous value was 95k25i7dd_4.  Here is what happened.  Remember when (mouse) hovering over the link produced the following target URL: http://localhost:8888/webcenter/spaces/NavigationTest/home This is great for the browser as this URL will navigate to the intended targer.  However, what is missing is the adf.ctrl-state parameter.  Since this parameter was not present upon navigation "within" the framework, the ADF framework produced another adf.ctrl-state (object).  The previous adf.ctrl-state basically is orphaned while continuing to be alive in memory.  Note: the auto-creation of the adf.ctrl state does happen initially when you invoke the Spaces application  for the first time.  The following is the line of code which produced the issue: <af:goLink destination="#{boilerBean.globalLogoURIInSpace} ... Here the boilerBean is responsible for returning the "string" url, which in this case is /spaces/NavigationTest/home. Unfortunately, again what is missing is adf.ctrl-state. Note: there are more than one instance of the goLinks in the sample templates. So E.T. how can I correct this? There are 2 simple fixes.  For the goLink's destination, use the navigation model to return the actually "node" value, then use the goLinkPrettyUrl method to add the current adf.ctrl-state: <af:goLink destination="#{navigationContext.defaultNavigationModel.node['home'].goLinkPrettyUrl}"} ... />  Note: the node value is the [navigation model id]  Using a goLink does solve the main issue.  However, since the link basically does a redirect, some browsers like IE will produce a somewhat significant "flash".  In a Spaces application, this may be an annoyance to the users.  Another way to solve the leakage problem, and also remove the flash between navigations is to use a af:commandLink.  For example, here is the code example for this scenario: <af:commandLink id="pt_cl2asf" actionListener="#{navigationContext.processAction}" action="pprnav">    <f:attribute name="node" value="#{navigationContext.defaultNavigationModel.node['home']}"/> </af:commandLink> Here, the navigation node to where home is located is delivered by way of the attribute to the commandLink.  The actual navigation is performed by the processAction, which is needing the "node" value. E.T. OK, you solved the OOTB sample BUG, what about my custom navigation code? I have seen many implementations of creating a navigation menu through custom code.  In addition, there are some blog sites that also give detailed examples.  The majority of these implementations are very similar.  The code usually involves using standard HTML tags (i.e. DIVS, UL, LI, .,etc) and either CSS or JavaScript (JQuery) to produce the flyout/drop-down effect.  The navigation links in these cases are standard <a href... > tags.  Although, this type of approach is not fully accepted by the ADF community, it does work.  The important thing to note here is that the <a> tag value must use the goLinkPrettyURL method of contructing the target URL.  For example: <a href="${contextRoot}${menu.goLinkPrettyUrl}"> The main reason why this type of approach is popular is that links that are created this way (also with using af:goLinks), the pages become crawlable by search engines.  CommandLinks are currently not search friendly.  However, in the case of a Spaces instance this may be acceptable.  So in this use-case, af:commandLinks, which would replace the <a>  (or goLink) tags. The example code given of the af:commandLink above is still valid. One last important item.  If you choose to use af:commandLinks, special attention must be given to the scenario in which java script has been used to produce the flyout effect in the custom menu UI.  In many cases that I have seen, the commandLink can only be invoked once, since there is a conflict between the custom java script with the ADF frameworks own scripting to control the view.  The recommendation here, would be to use a pure CSS approach to acheive the dropdown effects. One very important thing to note.  Due to another BUG, the WebCenter environement must be patched to BP3 (patch  p14076906).  Otherwise the leak is still present using the goLinkPrettyUrl method.  Thanks E.T.!  Now I can phone home and not worry about my application running out of resources due to my custom navigation!

• What to include in metadata?

  - by shyam

  I'm wondering if there are any general guidelines or best practices regarding when to split data into a metadata format, as oppose to directly embedding it within the data. (Specific example below). My understanding of metadata is that it describes data (without the need to actually look at the data), allowing for data to be quickly search/filtered for easy access. Let's take for example a simple 3D model format. The actual data file itself is a binary file containing vertices and colors. Things like creation date, modified data and author name would be things that describe the binary data, so I would say these belong as metadata (outside of the binary file). But what if the application had no need to search or filter by these fields? Would it be acceptable to embed these fields directly into the binary data itself? Could they be duplicated in both the binary data and the meta data, or would this be considered bad practice? What about more ambiguous fields such as the model name, which could be considered part of the data itself, but also as data describing the binary data?... How do you decide which data to embed in the actual binary file, as opposed to separating into a more flexible metadata format? Thanks!

• Update Manager won't open (error related to pythonverbose)

  - by Mateus Machado Luna

  I'm having an issue with update-manager. Last night, my computer restart suddenly during the update process. Now it won't open and it keep appearing on the notifier with a message warning that an error occurred. The error is the same that is displayed when I try to open it on the terminal: Error in sitecustomize; set PYTHONVERBOSE for traceback: EOFError: EOF read where not expected Traceback (most recent call last): File "/usr/bin/update-manager", line 26, in <module> from __future__ import print_function EOFError: EOF read where not expected I've already seen some questions here, but most of them are related to problems with ppas and the source.list file. This seems to be a bug on update-manager itself. I've already tried to remove it and install again, but the problem persists. I also noted another bug: my source-center doesn't open too. The message for it is similar to the other one: Error in sitecustomize; set PYTHONVERBOSE for traceback: EOFError: EOF read where not expected Traceback (most recent call last): File "/usr/lib/command-not-found", line 5, in <module> from __future__ import absolute_import, print_function EOFError: EOF read where not expected For now I'm using apt-get update && upgrade for updating and the Synaptic for the source management. But I really would like to fix this stuff. Anyone can help? I'm with Ubuntu 12.10, Gnome-remix, 64-bits.

• Vernon's book Implementing DDD and modeling of underlying concepts

  - by EdvRusj

  Following questions all refer to examples presented in Implementing DDD In article we can see from Figure 6 that both BankingAccount and PayeeAccount represent the same underlying concept of Banking Account BA 1. On page 64 author gives an example of a publishing organization, where the life-cycle of a book goes through several stages ( proposing a book, editorial process, translation of the book ... ) and at each of those stages this book has a different definition. Each stage of the book is defined in a different Bounded Context, but do all these different definitions still represent the same underlying concept of a Book, just like both BankingAccount and PayeeAccount represent the same underlying concept of a BA? 2. a) I understand why User shouldn't exist in Collaboration Context ( CC ), but instead should be defined within Identity and Access Context IAC ( page 65 ). But still, do User ( IAC ), Moderator ( CC ), Author ( CC ),Owner ( CC ) and Participant ( CC ) all represent different aspects of the same underlying concept? b) If yes, then this means that CC contains several model elements ( Moderator, Author, Owner and Participant ), each representing different aspect of the same underlying concept ( just like both BankingAccount and PayeeAccount represent the same underlying concept of a BA ). But isn't this considered a duplication of concepts ( Evan's book, page 339 ), since several model elements in CC represent the same underlying concept? c) If Moderator, Author ... don't represent the same underlying concept, then what underlying concept does each represent? 3. In an e-commerce system, the term Customer has multiple meanings ( page 49 ): When user is browsing the Catalog, Customer has different meaning than when user is placing an Order. But do these two different definitions of a Customer represent the same underlying concept, just like both BankingAccount and PayeeAccount represent the same underlying concept of a BA? thanks

• OWB 11gR2 &ndash; JDBC Helper Utility

  - by David Allan

  One of the common queries when importing the tables via JDBC with 11gR2 is determining why the import wizard doesn’t display the tables that you think it should. I often just use the script below to dump out the schemas, tables and columns that the JDBC driver is returning. This is useful in a few areas; to figure out what the schema name is returned to double check with the schema name you have used in the location (this is used in the DatabaseMetaData.getTables API call within the basic JDBC metadata import. to figure out the data types returned from the JDBC driver when you see columns skipped because of no datatype supported messages. also…I can do it via scripting and don’t need to recompile classes and stuff :-) Edit the tcl script and set the JDBC driver, the connection URL and the username and password (they are at the bottom of the script), the script then calls a basic tcl procedure which writes to standard out the schemas, tables and columns with various properties. For example I executed it using the XML JDBC driver from ODI over a simple customers XML file and it writes the following metadata; You can add more details as you need and execute from the OMBPlus panel within OWB. Download the sample tcl jdbc script here There is a bunch of really useful stuff on OTN documenting this area (start with the white paper here) that is worth checking out all related to the OWB SDK covering everything from platform definitions, custom metadata importers, application adapters, code templates etc. You can find a bunch of goodies on the OWB SDK here.

• Source-control your BI Publisher reports

  - by Dmitry Nefedkin

  Version control systems (VCS) like Subversion, Git and the others has been widely adopted and became the must-have tool in any software development project. Source artifacts and checked out, modified, checked in, all the history of changes is tracked by the VCS.  But what if the development tool stores the source/configuration artifacts not in your laptop's hard drive, but in some shared repository instead? Well, we definitely need a way for export/import our artifacts from/to this repository.   Oracle BI Publisher report development approach is based on such a shared repository model (catalog), and starting from BI Publisher 11.1.1.5 Oracle ships Catalog Utility, which can be utilized to export/import the reports from the command line.  To start using the BI Publisher Catalog Utility you should: Go to the file system of the server where BI Publisher binaries has been installed and locate the following file: <MW_HOME>/Oracle_BI1/clients/bipublisher/BIPCatalogUtil.zip Copy the file to your local filesystem and unzip it. I will refer to this unzipped directory as <BIP_CLIENT_DIR> below If you do not want to pass server BI Publisher server URL, username and password during each invocation, modify the corresponding values inside <BIP_CLIENT_DIR>/config/xmlp-client-config.xml Open the terminal window and go to <BIP_CLIENT_DIR>/bin Make sure that the following environment variables are set: JAVA_HOME, ORACLE_HOME Now it's time to run the utility: if you are on Linux - just run BIPCatalogUtil.sh and pass the parameters according to the utility documentation if you are on MS Windows the bad news are that the command script for MS Windows is missing, and support.oracle.com note 1333726.1 says that a temporary solution is "create a .cmd file by setting up a classpath and copying the same commands from the .sh script". The good news are that I've created this script already,  please download the it from GitHub Hope you will find this utility useful during you day-by-day BI Publisher development.

• Script to recursively grep data from certain files in the directory

  - by Jude

  I am making a simple shell script which will minimize the time I spend in searching all directories under a parent directory and grep some things inside some files. Here's my script. #!/bin/sh MainDir=/var/opt/database/1227-1239/ cd "$MainDir" for dir in $(ls); do grep -i "STAGE,te_start_seq Starting" "$dir"/his_file | tail -1 >> /home/xtee/sst-logs.out if [ -f "$dir"/sysconfig.out]; then grep -A 1 "Drive Model" "$dir"/sysconfig.out | tail -1 >> /home/xtee/sst-logs.out else grep -m 1 "Physical memory size" "$dir"/node0/setupsys.out | tail -1 >> /home/xtee/sst-logs.out fi done The script is supposed to grep the string STAGE,te_start_seq Starting under the file his_file then dump it sst-logs.out which it does. My problem though is the part in the if statement. The script should check the current directory for sysconfig.out, grep drive model and dump it to sst-logs.out if it exists, otherwise, change directory to node0 then grep physical memory size from setupsys.out and dump it to sst-logs.out. My problem is, it seems the if then else statement seems not to work as it doesn`t dump any data at all but if i execute grep manually, i do have data. What is wrong with my shell script? Is there any more efficient way in doing this?

• How can I prevent seams from showing up on objects using lower mipmap levels?

  - by Shivan Dragon

  Disclaimer: kindly right click on the images and open them separately so that they're at full size, as there are fine details which don't show up otherwise. Thank you. I made a simple Blender model, it's a cylinder with the top cap removed: I've exported the UVs: Then imported them into Photoshop, and painted the inner area in yellow and the outer area in red. I made sure I cover well the UV lines: I then save the image and load it as texture on the model in Blender. Actually, I just reload it as the image where the UVs are exported, and change the viewport view mode to textured. When I look at the mesh up-close, there's yellow everywhere, everything seems fine: However, if I start zooming out, I start seeing red (literally and metaphorically) where the texture edges are: And the more I zoom, the more I see it: Same thing happends in Unity, though the effect seems less pronounced. Up close is fine and yellow: Zoom out and you see red at the seams: Now, obviously, for this simple example a workaround is to spread the yellow well outside the UV margins, and its fine from all distances. However this is an issue when you try making a complex texture that should tile seamlessly at the edges. In this situation I either make a few lines of pixels overlap (in which case it looks bad from upclose and ok from far away), or I leave them seamless and then I have those seams when seeing it from far away. So my question is, is there something I'm missing, or some extra thing I must do to have my texture look seamless from all distances?

• REST Service and CQRS

  - by Paul Wade

  I am struggling with architecture on a new project. I am using the following patterns/technology. CQRS - anything going in goes through a command REST - using WebAPI MVC - asp.net mvc Angular - building a spa nhibernate I belive this provides some great separation and should help keep a very complex domain from growing into a giant set of services that mix queries with other business logic. The REST services have become non restful. They are putting methods in rest that are "SearchByDate", "SearchByItem" etc. Service Methods that execute commands are called with a "web" model class, a new command is built in the service and executed, I feel like there is a lot of extra code. I expected this to be much different but I wasn't around to keep things on track. Finally my questions are this... I would have liked to see PUT Person (CreatePersonCommand) but then I realized that isn't restful either is it? the put should be a person entity not a command. Can I make CQRS and REST service work together or am I going about this all wrong? How do I handle service methods that don't fit into a REST model. I am not performing CRUD on the object but rather executing some business logic. I.E. I don't want the UI to be responsible for how a shipment is "unshipped" I want the service layer to worry about that.

• Pygame: Save a list of objects/classes/surfaces

  - by Sam Tubb

  I am working on a game, in which you can create mazes. You place blocks on a 16x16 grid, while choosing from a variety of block to make the level with. Whenever you create a block, it adds this class: class Block(object): def __init__(self,x,y,spr): self.x=x self.y=y self.sprite=spr self.rect=self.sprite.get_rect(x=self.x,y=self.y) to a list called instances. I tried shelving it to a .bin file, but it returns some error dealing with surfaces. How can I go about saving and loading levels? Any help is appreciated! :) Here is the whole code for reference: import pygame from pygame.locals import * #initstuff pygame.init() screen=pygame.display.set_mode((640,480)) pygame.display.set_caption('PiMaze') instances=[] #loadsprites menuspr=pygame.image.load('images/menu.png').convert() b1spr=pygame.image.load('images/b1.png').convert() b2spr=pygame.image.load('images/b2.png').convert() currentbspr=b1spr curspr=pygame.image.load('images/curs.png').convert() curspr.set_colorkey((0,255,0)) #menu menuspr.set_alpha(185) menurect=menuspr.get_rect(x=-260,y=4) class MenuItem(object): def __init__(self,pos,spr): self.x=pos[0] self.y=pos[1] self.sprite=spr self.pos=(self.x,self.y) self.rect=self.sprite.get_rect(x=self.x,y=self.y) class Block(object): def __init__(self,x,y,spr): self.x=x self.y=y self.sprite=spr self.rect=self.sprite.get_rect(x=self.x,y=self.y) while True: #menu items b1menu=b1spr.get_rect(x=menurect.left+32,y=48) b2menu=b2spr.get_rect(x=menurect.left+64,y=48) menuitems=[MenuItem(b1menu,b1spr),MenuItem(b2menu,b2spr)] screen.fill((20,30,85)) mse=pygame.mouse.get_pos() key=pygame.key.get_pressed() placepos=((mse[0]/16)*16,(mse[1]/16)*16) if key[K_q]: if mse[0]<260: if menurect.right<255: menurect.right+=1 else: if menurect.left>-260: menurect.left-=1 else: if menurect.left>-260: menurect.left-=1 for e in pygame.event.get(): if e.type==QUIT: exit() if menurect.right<100: if e.type==MOUSEBUTTONUP: if e.button==1: to_remove = [i for i in instances if i.rect.collidepoint(placepos)] for i in to_remove: instances.remove(i) if not to_remove: instances.append(Block(placepos[0],placepos[1],currentbspr)) for i in instances: screen.blit(i.sprite,i.rect) if not key[K_q]: screen.blit(curspr,placepos) screen.blit(menuspr,menurect) for item in menuitems: screen.blit(item.sprite,item.pos) if item.rect.collidepoint(mse): if pygame.mouse.get_pressed()==(1,0,0): currentbspr=item.sprite pygame.draw.rect(screen, ((255,0,0)), item, 1) pygame.display.flip()

• How to determine the end of list has been reached?

  - by Sweta Dwivedi

  I'm trying to animate my object according to a set of recorded values from kinect skeleton stream by saving the (x,y,z) stream from the skeletal data into a list and then set my objects x and y position from the x,y of the list. However, once the list end has been reached it starts to animate again from the start. I don't want that - I just want the model position to keep going in the positive X direction. Is there any way I can check if end of the list has been reached and to just update the model position in x direction? Or is there any other way to continue moving my sprite once the points in the list are over... i dont want it to start animating all the way again.. protected override void Update(GameTime gameTime) { //position += spriteSpeed * (float)gameTime.ElapsedGameTime.TotalSeconds; //// TODO: Add your update logic here using (StreamReader r = new StreamReader(f)) { string line; Viewport view = graphics.GraphicsDevice.Viewport; int maxWidth = view.Width; int maxHeight = view.Height; while((line = r.ReadLine()) != null) { string[] temp = line.Split(','); int x = (int) Math.Floor(((float.Parse(temp[0]) * 0.5f) + 0.5f) * maxWidth); int y = (int) Math.Floor(((float.Parse(temp[1]) * -0.5f) + 0.5f) * maxHeight); motion_2.Add(new Point(x, y)); } } position.X = motion_2[i].X; position.Y = motion_2[i].Y; i++; a_butterfly_up.Update(gameTime); a_butterfly_side.Update(gameTime); G_vidPlayer.Play(mossV); base.Update(gameTime); }

• MEF, IServiceProvider and Testing Visual Studio Extensions

  - by Daniel Cazzulino

  In the latest and greatest version of Visual Studio, MEF plays a critical role, one that makes extending VS much more fun than it ever was. So typically, you just [Export] something, and then someone [Import]s it and that's it. MEF in all its glory kicks in and gets all your dependencies satisfied. Cool, you say, so let's now import ITextTemplating and have some T4-based codegen going! Ah, if only it was that easy. Turns out by default, none of the VS built-in services are exposed to MEF, apparently because there wasn't enough time to analyze the lifetime, initialization, dependencies, etc. for each one before launch, which makes perfect sense. You don't want to blindly export everything now just in case. There's also the whole VS package initialization thing which in this version of VS is not so transparently integrated with the MEF publishing side (i.e. a MEF export from a package can get instantiated before its owning package, and in fact, the package can remain unloaded forever and the export will continue to be visible to anyone)....Read full article

• Thread safe GUI programming

  - by James

  I have been programming Java with swing for a couple of years now, and always accepted that GUI interactions had to happen on the Event Dispatch Thread. I recently started to use GTK+ for C applications and was unsurprised to find that GUI interactions had to be called on gtk_main. Similarly, I looked at SWT to see in what ways it was different to Swing and to see if it was worth using, and again found the UI thread idea, and I am sure that these 3 are not the only toolkits to use this model. I was wondering if there is a reason for this design i.e. what is the reason for keeping UI modifications isolated to a single thread. I can see why some modifications may cause issues (like modifying a list while it is being drawn), but I do not see why these concerns pass on to the user of the API. Is there a limit imposed by an operating system? Is there a good reason these concerns are not 'hidden' (i.e. some form of synchronization that is invisible to the user)? Is there any (even purely conceptual) way of creating a thread safe graphics library, or is such a thing actually impossible? I found this http://blogs.operationaldynamics.com/andrew/software/gnome-desktop/gtk-thread-awareness which seems to describe GTK differently to how I understood it (although my understanding was the same as many people's) How does this differ to other toolkits? Is it possible to implement this in Swing (as the EDT model does not actually prevent access from other threads, it just often leads to Exceptions)

• Why isn't there a culture of paying for frameworks?

  - by Marty Pitt

  One of the side effects of the recent trend of "Lean" startups, and the app store era, is that consumers are more acclimatised to paying small prices for small games / products. Eg.: Online SAAS that charges ~$5 / month (the basecamp style of product) Games which are short, fun, and cheap ($0.99 from the app store This market has been defined by "doing one thing well, and charging people for it." DHH of Rails / 37 Signals fame argues that if your website isn't going to make money, don't bother making it. Why doesn't the same rule apply to frameworks? There are lots of software framework projects out there - many which are mature and feature-rich, which offer developers significant value, yet there doesn't seem to be a market or culture of paying for these. It seems that the projects which do charge money are often things like UI component toolsets, and are often marginalized in favour of free alternatives. Why is this? Surely programmers / businesses see the value in contributing back to projects such as Ruby, Rails, Hibernate, Spring, Ant, Groovy, Gradle, (the list goes on). I'm not suggesting that these frameworks should start charging for anyone who wants to use them, but that there must be a meaningful business model that would allow the developers to earn money from the time they invest developing the framework. Any thoughts as to why this model hasn't emerged / succeeded?

• Simple Architecture Verification

  - by Jean Carlos Suárez Marranzini

  I just made an architecture for an application with the function of scoring, saving and loading tennis games. The architecture has 2 kinds of elements: components & layers. Components: Standalone elements that can be consumed by other components or by layers. They might also consume functionality from the model/bottom layer. Layers: Software components whose functionality rests on previous layers (except for the model layer). -Layers: -Models: Data and it's behavior. -Controllers: A layer that allows interaction between the views and the models. -Views: The presentation layer for interacting with the user. -Components: -Persistence: Makes sure the game data can be stored away for later retrieval. -Time Machine: Records changes in the game through time so it's possible to navigate the game back and forth. -Settings: Contains the settings that determine how some of the game logic will apply. -Game Engine: Contains all the game logic, which it applies to the game data to determine the path the game should take. This is an image of the architecture (I don't have enough rep to post images): http://i49.tinypic.com/35lt5a9.png The requierements which this architecture should satisfy are the following: Save & load games. Move through game history and see how the scoreboard changes as the game evolves. Tie-breaks must be properly managed. Games must be classified by hit-type. Every point can be modified. Match name and player names must be stored. Game logic must be configurable by the user. I would really appreciate any kind of advice or comments on this architecture. To see if it is well built and makes sense as a whole. I took the idea from this link. http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller

• Why would accessing photos over a network be a problem for Digikam?

  - by Shedeki

  Digikam has always worked nicely for me. I recently setup a Synology DiskStation (DS212+) and moved all my pictures to it, keeping them in an encrypted folder. I mount that folder using cifs, as some bug prevents eCryptfs and NFS from working together. This has led Digikam to being incredibly slow. Startup takes a very long time (several minutes for 41779 items, 123.8GB) but worse is how long it takes Digikam to write files. I like using Digikams import feature to copy new images from my camera to the hard drive because it checks for duplicates as well as creating a clear folder structure according to the dates the images were taken. Since I moved to using the network drive Digikam takes about 5 to 10 times as long to import photos than it did before. Saving modified or converted images takes equally long. What I am looking for is a way to help Digikam speed things up or an alternative piece of software (I have never liked Digikam being so very much KDEish…). There are just so many features that only Digikam seems to combine, e.g.: Batch processing. Respects existing folder structure. Does not mess up files for other applications. *.NEF support. Caches thumbnails in a clean way.
