• Game Trees Conceptual Question

  - by Chris Corbin

  I am struggling to conceptually understand a question in a programming assignment for an algorithms class. The problem is dealing with a fictitious 2 player game, named Easy. The rules of the game are simple; each player may chose one of 4 integers {0-3} after which that integer is not available for the other player. The catch is, a player picks {0} it means they quit. The objective is for Player 1 to get {1} and Player 2 to get {2}, in which case they may win, however if both or neither succeed, then the game ends in a draw. I have been asked to draw the game tree for Easy, showing all nodes, which they explained as 4! = 24. Labeling the edges, which represent moves (selecting a number) and the leaves with who won (1 means Player 1 won, -1 means Player 2 won, and 0 means a tie). I have drawn out a game tree, which I believe is correct, however I am not 100% certain hence I am asking the question. My game tree only has 16 leaves. I am thinking that when a player picks {0}, and then quits, the game tree stops there? I don't see how it is possible to get to 24 leaves? Any help would be greatly appreciate, and if you need more information I would be happy to provide it. Thanks

• What is the best way to design a table with an arbitrary id?

  - by P.Brian.Mackey

  I have the need to create a table with a unique id as the PK. The ID is a surrogate key. Originally, I had a natural key, but requirement changes have undermined this idea. Then, I considered adding an auto incrementing identity. But, this presents problems. A. I can't specify my own ID. B. The ID's are difficult to reset. Both of these together make it difficult to copy over this table with new data or move the table across domains, e.g. Dev to QA. I need to refer to these ID's from the front end, JavaScript...so they must not change. So, the only way I am aware of to meet all these challenges is to make a GUID ID. This way, I can overwrite the ID's when I need to or I can generate a new one without concern for order (E.G. an int based id would require I know the last inserted ID). Is a GUID the best way to accomplish my goals? Considering that a GUID is a string and joining on a string is an expensive task, is there a better way?

• How to visualize the design of a program in order to communicate it to others

  - by Joris Meys

  I am (re-)designing some packages for R, and I am currently working out the necessary functions, objects, both internal and for the interface with the user. I have documented the individual functions and objects. So I have the description of all the little parts. Now I need to give an overview of how the parts fit together. The scheme of the motor so to say. I've started with making some flowchart-like graphs in Visio, but that quickly became a clumsy and useless collection of boxes, arrrows and-what-not. So hence the question: Is there specific software you can use for vizualizing the design of your program If so, care to share some tips on how to do this most efficiently If not, how do other designers create the scheme of their programs and communicate that to others? Edit: I am NOT asking how to explain complex processes to somebody, nor asking how to illustrate programming logic. I am asking how to communicate the design of a program/package, i.e.: the objects (with key features and representation if possible) the related functions (with arguments and function if possible) the interrelation between the functions at the interface and the internal functions (I'm talking about an extension package for a scripting language, keep that in mind) So something like this : But better. This is (part of) the interrelations between functions in the old package that I'm now redesigning for obvious reasons :-) PS : I made that graph myself, using code extraction tools on the source and feeding the interrelation matrix to yEd Graph Editor.

• Comparing the Performance of Visual Studio's Web Reference to a Custom Class

  As developers, we all make assumptions when programming. Perhaps the biggest assumption we make is that those libraries and tools that ship with the .NET Framework are the best way to accomplish a given task. For example, most developers assume that using ASP.NET's Membership system is the best way to manage user accounts in a website (rather than rolling your own user account store). Similarly, creating a Web Reference to communicate with a web service generates markup that auto-creates a proxy class, which handles the low-level details of invoking the web service, serializing parameters, and so on. Recently a client made us question one of our fundamental assumptions about the .NET Framework and Web Services by asking, "Why should we use proxy class created by Visual Studio to connect to a web service?" In this particular project we were calling a web service to retrieve data, which was then sorted, formatted slightly and displayed in a web page. The client hypothesized that it would be more efficient to invoke the web service directly via the HttpWebRequest class, retrieve the XML output, populate an XmlDocument object, then use XSLT to output the result to HTML. Surely that would be faster than using Visual Studio's auto-generated proxy class, right? Prior to this request, we had never considered rolling our own proxy class; we had always taken advantage of the proxy classes Visual Studio auto-generated for us. Could these auto-generated proxy classes be inefficient? Would retrieving and parsing the web service's XML directly be more efficient? The only way to know for sure was to test my client's hypothesis. Read More >

• Example of persisting an inheritance relationship using ORM

  - by Schemer

  I have some experience with OOP and RDBs, but very little exposure to web programming. I am trying to understand what non-trivial types of problems are solved by ORM. Of course, I am familiar with the need for data persistence, but I have never encountered a need for persisting relationships between objects, a situation which is indicated in many online articles about ORM. I am not asking about the process of persisting a POJO to a database and restoring it later. Nor am I asking about why ORM frameworks are useful -- or a pain in the butt -- for doing so. I am particularly interested in how the need arises to persist and restore relationships between objects. In various documentation, I have seen many examples of persisting POJOs to a database, but the examples have all been for only very simple objects that are essentially nothing more than records anyway: a constructor, some private fields, and getter/setter methods. The motivation for persisting such an "object-record" seems obvious and trivial. This example: Hibernate ORM Tutorial offers such an example, but goes on to discuss mismatch issues of granularity, inheritance, identity, associations, and navigation that are not motivated by the example. If someone could offer a toy example of an instance where, say, the need arises to persist an inheritance relationship, I would be grateful. This might be blindingly obvious for anyone who has already encountered this situation but I have not and a great deal of searching and reading have not turned up any examples.

• What benefits can I get upgrading my ASP.NET (Webform) + DAL(EF) + Repository + BLL structure to MVC?

  - by Etienne

  I'm in the process of defining an approach that may best fit our needs for a big web application development. For now, I'm thinking going with an ASP.NET Architecture with a DAL using Entity Framework, a Repository concept to not access DAL directly from BLL and a BLL that call the repository and make every manipulations necessary to prepare data to push in a presentation layer (.aspx files). I don't plan to use ASP.Net controls and prefer to keep things simple and lightweight using plain html, jQuery UI controls and do most of the server calls with jQuery Ajax. Sometimes, when needed, I plan to use handlers (.ashx) to call BLL methods that will return JSON or HTML to client for dynamic stuff. My solution also has a test project that Mock the Repository with in-memory data to not repose on database for testing BLL methods... It may be usefull to add that we will build a big application over this architecture with hundreds of tables and store procedures with a lot of reading and writing to database. My question is, having this architecture in mind, Is there any evident advantages that I can obtain by using an MVC3 project instead of the described architecture base on Webform? Do you see any problem in this architecture that may cause us problem during the next steps of development? I know the MVC pattern for using it in others projects with Django... but the Microsoft MVC implementation look so much more complex and verbose than Django MVC and it's why I'm hesitating (or waiting for a little push?) right now before jumping into it... We are in a real project with deadlines and don't want to slow the development process without any real benefits.

• installing ubuntu on SSD

  - by kunal

  Going to install Ubuntu 10.10 on new intel x25M 80GB SSD. It will be fresh install. I have been googling for past few days and getting overwhelming articles/blogs/Q&As. One particularly very useful being: Optimize for SSD (I could not post other links as i dont have enough credits) But with so many suggestions and differences of opinions (on different links) this simple OS install process seems to be daunting task to me and I really want to stick with ubuntu (although have used for very short period of time). Can someone help me by answering few questions (yes they are repeated as i couldnt comprehend the answers elsewhere) which file system (ext2/3/4 or something else)? (consider SSD life) can it be changed after installation? should i partition the disk? (as we do in traditional HDD) for now, no plan of dual booting. Only ubuntu will live on scarce space of 80GB SSD. i have 2 GB RAM, should i still allocate swap space (if i dont allocate swap space, can i still hibernate the machine)? will swap space impact SSD life? should i consider putting additional 1GB RAM to avoid swap space? Linux experience - absolute novice intended usage - heavy browsing, programming, regular video/music and some other non-CPU/RAM-intensive programs. will backup big files to an external hard drive. laptop config - 3 yr old vaio, core2 duo, 2GB RAM Please pardon the repetition and i really appreciate anyone helping me getting started with ubuntu.

• Activate Your Monitor via Motion Trigger

  - by ETC

  Most people are in the habit of jiggling their mouse or tapping their keyboard when they want to wake their monitor. This clever electronics hack adds a sensor to your computer for motion-based monitor activation. At the DIY and electronics blog Radio Etcetera they tackled an interesting project and shared the build guide. Their local volunteer fire department needed a monitor on for quick information checks but they didn’t need it on all the time and they didn’t want to have to walk over and activate the monitor when they needed it. The solution involved hacking a simple infrared security sensor and wiring it via USB to send a mouse command when motion is detected in the room. Fire fighter walks in, monitor turns on and displays information; fire fighter leaves and the monitor goes back to sleep.

• Game editor integration with the engine?

  - by Daniel

  What I am trying to figure out is what is the best way to integrate the editor(level, effects, model, etc...) in the most effective way? Now the first thing I thought would be to create the game engine(*) extremely modular. For example I took the example of game states. You could have multiple game states that all have their own update() and draw() methods among others. Each game state class would inherit from a base GameState class. This allows for a more modular approach and a useful one at that. Now would the most efficient approach be to implement the editor along with the modular engine, or create two different designs for both the game, and editor? I thought to take the game state example and extend it to window states, and well could be used for a lot more systems. Is there a better implementation of this design(game state) for use in other systems used in the engine? *: Now I know the term game engine is sorta irrelevant, and misused in many situations. What I am referring to as the "game engine" is the combination of the systems that the game must interact with for short. Also this is more of a theory / design question than an implementation. Even though both mix, i'd rather like to have a more general idea on how the editor is built in an efficient way and still using the same engine code as what the game uses. Thanks, Daniel P.S If you need more clarification or extra bits just leave a comment.

• How to show or direct a business analyst to a data modelling subject?

  - by AaronLS

  Our business analysts pushed hard to collect data through a spreadsheet. I am the programmer responsible for importing that data. Usually when they push hard for something like this, I never know how well it will work out until a few weeks later when I have time assigned to work on the task of programming the import of the data. I have tried to do as much as possible along the way, named ranges, data validations, etc. But I usually don't have time to take a detailed look at all the data and compare to the destination in the database to determine how well it matches up. A lot of times there will be maybe a little table of items that somehow I have to relate to something else in the database, but there are not natural or business keys present that would allow me to do so. Make the best of this, trying to write something that can compare strings and make a best guess at it and then go through the effort of creating interfaces for a user to match the imported data to the destination. I feel like if the business analyst was actually creating a data model, they would be forced to think about these relationships, and have an appreciation for the need of natural or business keys to be part of the spreadsheet for the purposes of smoothly importing the data. The closest they come to business analysis is a big flat list of fields, and that would be fine if it were like any other data dictionary and include data types+relationships, but it isn't. They are just a bunch of names. No indication of what type of data they might hold, and it is up to me to guess. When I have pushed for more detail, they say that it is just busy work. How can I explain the importance of data modelling? How can I tell them what it is and how to do it? It feels impossible, because they don't have an appreciation for its importance. They do however, usually have an interest in helping out in whatever way they can, it's just this in particular has never gotten a motivated response.

• Code maintenance: keeping a bad pattern when extending new code for being consistent or not ?

  - by Guillaume

  I have to extend an existing module of a project. I don't like the way it has been done (lots of anti-pattern involved, like copy/pasted code). I don't want to perform a complete refactor. Should I: create new methods using existing convention, even if I feel it wrong, to avoid confusion for the next maintainer and being consistent with the code base? or try to use what I feel better even if it is introducing another pattern in the code ? Precison edited after first answers: The existing code is not a mess. It is easy to follow and understand. BUT it is introducing lots of boilerplate code that can be avoided with good design (resulting code might become harder to follow then). In my current case it's a good old JDBC (spring template inboard) DAO module, but I have already encounter this dilemma and I'm seeking for other dev feedback. I don't want to refactor because I don't have time. And even with time it will be hard to justify that a whole perfectly working module needs refactoring. Refactoring cost will be heavier than its benefits. Remember: code is not messy or over-complex. I can not extract few methods there and introduce an abstract class here. It is more a flaw in the design (result of extreme 'Keep It Stupid Simple' I think) So the question can also be asked like that: You, as developer, do you prefer to maintain easy stupid boring code OR to have some helpers that will do the stupid boring code at your place ? Downside of the last possibility being that you'll have to learn some stuff and maybe you will have to maintain the easy stupid boring code too until a full refactoring is done)

• Portal and Content - Components, part 3 – Applied Customization Framework (4 of 7)

  - by Stefan Krantz

  Have you ever been challenged with the situation where your work task asks you to implement functionality in the WebCenter Portal and you browse through the Resource Catalog (Business Dictionary) and find the functionality you need. However when you get started there is small short comings and you ask your self- how can I re-use what is out of the box ca?- I wonder what code I need to use to produce the similar functions and include my new requirements?- Must I write a new taskflow? The answer to above questions are in many times answered with simply you can  do a taskflow customization to out-of-the-box taskflows. In this post I will help you understand how to do such customization. Best described is a 4 step process, see image flow below for illustration: Just to clarify few naming confusions that might occur when go through above process. Customization Role is a function within JDeveloper that will allow you to implement view and flow customizations to existing taskflows WebCenter Portal – Spaces Taskflow Customization Framework this technology scope do not only refer to WebCenter Spaces, this also include WebCenter Portal/Framework A taskflow customization do not overwrite or replace any code, it just creates an additional tip view of the taskflow in the MDS for the current application (WebCenter Portal or WebCenter Spaces) To sum up this simple procedure I also like to help you find your way around the main topic for this post series, this post series is focusing primarily on Content integration with WebCenter Portal, so where can I find content related taskflows in the WebCenter Libraries. The list below mention some useful locations to taskflows and each taskflow page fragments. Library Reference - WebCenter Document Library Service View Content Presenter Path: oracle.webcenter.doclib.view.jsf.taskflows.presenterTaskflow: contentPresenter.xml - The Content Presenter taskflowTaskflow: contentPresenterWizard.xml - The publishing wizard to select content, select template and preview including contributionDocument Manager Path: oracle.webcenter.doclib.view.jsf.taskflows.docManager Taskflow: documentManager.xml - The Document Manager taskflow which includes references to document management feature including browsing, download, uploading and viewing.

• Bulk Rename Tool is a Lightweight but Powerful File Renaming Tool

  - by Jason Fitzpatrick

  There’s no need to settle for overly simplistic file renaming tools as long as Bulk Rename Tool is around. It’s lightweight, insanely customizable, portable, and sure to make short work of any renaming task you throw at it. Bulk Rename Tool is a great portable application (available as an installed version if you crave context menu integration) that blasts through file renaming tasks. The main panel is intimidatingly packed with toggles and variables you can alter; this isn’t a one-click solution by any means. That said, once you get comfortable using the interface it’s lightening fast and extremely flexible. One tip that will save you an enormous amount of frustrating when you get started: make sure to highlight the files you want to change in the file preview window (located in the upper right corner) or else you won’t see the preview and won’t know if the changes you’re making in the control panel are yielding the file names you desire.

• Inheriting projects - General Rules?

  - by pspahn

  This is an area of discussion I have long been curious about, but overall, I generally lack the experience to give myself an answer that I would fully trust. We've all been there, a new client shows up with a half-complete project they are looking to finish and launch. For whatever reason, they fired their previous developer, and it's now up to you to save the day. I am just finishing up a code review for a new client, and in my estimation is would be better to scrap what the previous developers built since and start from scratch. There's a ton of reasons why I am leaning toward this way, but it still makes me nervous since the client isn't going to want to hear "those last guys built you a big turd, and I can either polish it, or throw it in the trash". What are your general rules for accepting these projects? How do you determine whether it will be better to start from scratch or continue with the existing code base? What other extra steps might you take to help control client expectations, since the previous developer may have inflated those expectations beyond a reasonable level? Any other general advice?

• problem adding bumpmap to textured gluSphere in JOGL

• Long term plan of attack to learn math?

  - by zhenka

  I am a web-developer with a desire to expand my skill-set to mathematics relevant to programming. As 2nd career, I am stuck in college doing some of the requirements while working. I was hoping the my education will teach me the needed skills to apply math, however I am quickly finding it to be too much easily-testable breadth-based approach very inefficient for the time invested. For example in my calculus 2 class, the only remotely useful mind expanding experience I had was volumes and areas under the curve. The rest was just monotonous glorified algebra, which while comes easy to me, could be done by software like wolfram alpha within seconds. This is not my idea of learning math. So here I am a frustrated student looking for a way to improve my understanding of math in a way that focuses on application, understanding and maximally removed needless tedium. However I cannot find a good long term study strategy with this approach in mind. So for those of like mind, how would you go about learning the necessary math without worrying too much about stuff a computer can do much better?

• Orthographic unit translation mismatch on grid (e.g. 64 pixels translates incorrectly)

  - by Justin Van Horne

  I am looking for some insight into a small problem with unit translations on a grid. Setup 512x448 window 64x64 grid gl_Position = projection * world * position; projection is defined by ortho(-w/2.0f, w/2.0f, -h/2.0f, h/2.0f); This is a textbook orthogonal projection function. world is defined by a fixed camera position at (0, 0) position is defined by the sprite's position. Problem In the screenshot below (1:1 scaling) the grid spacing is 64x64 and I am drawing the unit at (64, 64), however the unit draws roughly ~10px in the wrong position. I've tried uniform window dimensions to prevent any distortion on the pixel size, but now I am a bit lost in the proper way in providing a 1:1 pixel-to-world-unit projection. Anyhow, here are some quick images to aide in the problem. I decided to super-impose a bunch of the sprites at what the engine believes is 64x offsets. When this seemed off place, I went about and did the base case of 1 unit. Which seemed to line up as expected. The yellow shows a 1px difference in the movement. Vertices It would appear that the vertices going into the vertex shader are correct. For example, in reference to the first image the data looks like this in the VBO: x y x y ---------------------------- tl | 0.0 24.0 64.0 24.0 bl | 0.0 0.0 -> 64.0 0.0 tr | 16.0 0.0 80.0 0.0 br | 16.0 24.0 80.0 24.0 With that said, all I am left to believe is that I am munging up my actual projection. So, I am looking for any insight into maintaining the 1:1 pixel-to-world-unit projection.

• Experience vs. versatility

  - by Florin Bombeanu

  Let's say a .NET programmer works at a company which provides software on demand, not as a product. The programmer works in WPF for a period of time and he/she invests lots of time in it. He/she get very good at WPF and Windows Forms and desktop development in general. But the company has to provide a web application now, so the developer has to learn MVC or Web Forms. He/she is not experienced in web development so he/she starts investing time in this new technology and in time they get good at it. But this time the company has to provide a Sharepoint solution, and so on. What is more important: Being very very good at a certain technology, Or be as versatile as possible knowing less in each technology but covering a greater area of expertise? Should the programmer keep studying and working in WPF until he/she reaches a guru level or is it a good thing that they had to learn other technologies as well? I agree with those of you who will say that when learning different technologies you will also learn things which are useful no matter the technology you're programming in. But eventually, when the programmer will want to change jobs, will it matter more that he/she knows some WPF, MVC or Sharepoint than the fact that he/she is insanely good at one of them? I would think the second one is more important since most companies are looking for a developer for a certain technology. I don't think there are many companies looking for technical know-it-all people. What do you think?

• Report Books and Parameters with Telerik Reporting

  Telerik Reporting provides a simple, yet powerful, component called the ReportBook that allows multiple reports to be combined into one. Doing so makes displaying, printing, and exporting multiple reports a much simpler task for end users. Providing this type of functionality does leave one question though, "How are report parameters handled?" This entry will focus on providing the answers to that simple question. Click here to download the sample code so you can follow along. Creating a ReportBook ReportBooks are supported in all three environments the ReportViewer supports, WinForms, Silverlight, and ASP.NET. Adding a ReportBook to each of these environments is very similar. This example focuses on using a ReportBook with the WinForms ReportViewer. Create a WinForms Application Add a reference to the project containing the reports. Drag a ReportViewer from the ToolBox into the designer. Drag a ReportBook from the ToolBox into the designer. A dialog will be displayed asking for the reports to be included in the ReportBook....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Woman Is the World's First Computer Programmer? [closed]

  - by Sveta Bondarenko

  This week, on 10th December, we celebrate the 197th birth anniversary of Ada Lovelace, often considered as the world's first computer programmer. Ada became famous not only as a daughter of romantic poet Lord Byron but also as an outstanding 19th century mathematician. Her works on analytical engine are recognized as the first algorithm intended to be processed by a machine. Women always played a crucial role in the computer science evolution, but unfortunately, they are considered to be not so good at programming and engineering as men. Even though the fair sex makes up a growing portion of computer and Internet users, there is still a large gender gap in the field of Computer Science. But all is not lost! According to the study women's enrollment in the computer science raised from 7 percent in 1995 to 42 percent in 2000. And it is still increasing. Soon women will take a well-deserved position among the world's top computer programmers. After all, a number of notable female computer pioneers such as Ada Lovelace, Grace Hopper, and Anita Borg have proven that women make great computer scientists. But will women make great contributions to the modern technologies industry? Or successful and famous female computer programmer is just a pipe dream?
