• Design: How to model / where to store relational data between classes

  - by Walker

  I'm trying to figure out the best design here, and I can see multiple approaches, but none that seems "right." There are three relevant classes here: Base, TradingPost, and Resource. Each Base has a TradingPost which can offer various Resources depending on the Base's tech level. Where is the right place to store the minimum tech level a base must possess to offer any given resource? A database seems like overkill. Putting it in each subclass of Resource seems wrong--that's not an intrinsic property of the Resource. Do I have a mediating class, and if so, how does it work? It's important that I not be duplicating code; that I have one place where I set the required tech level for a given item. Essentially, where does this data belong? P.S. Feel free to change the title; I struggled to come up with one that fits.

• Good Intro to Computer Science Book for FE Developer [on hold]

  - by Squirkle

  I am a JavaScript developer/architect who, like many developers these days, did not come from a Computer Science background (I studied Philosophy at a liberal arts college), but instead learned development by actually building applications, and by reading books explaining language grammars, design patterns, and best practices. I have never felt that my ignorance of CS concepts has hurt my ability to build great apps or find employment. Recently, however, I have felt the itch to grow in this direction. Do you have any suggestions for some good introductory CS resources/books? I know that Computer Science is a huge field and my question is very general, but I am looking for a 101-type survey of the high-level concepts, from which I can branch off into more specific areas of study. Thanks!

• How to study for an Informatics Olympiad [on hold]

  - by Cloud

  One of my goals for next year is to participate in the Australian Informatics Olympiad. As far as I'm aware, it is not too different from Informatics Olympiads in other countries. What would be the best way to study for this? What content should I pay particular attention to while learning in Python? I am currently using the book 'Learn Python the hard way', but are there any other books worthy of a mention? This is the link to their site: http://orac.amt.edu.au/aio/ It contains sample questions, so you can get an idea for the structure or nature of the competition. I know this isn't really a specific programming question, but it would be great if someone could share their experience or give some suggestions for me.

• How can I make sure my website will be available during a presentation?

  - by johnny_s

  I have an online presentation to do next week and I have it all ready to go. The website is HTML and CSS only (no DB), and currently resides on my shared hosting account. Now, although my shared hosting is (relatively) reliable, I have noticed that recently they have been making some changes and my website has been unavailable at times. I don't want this to happen to me on the morning of my presentation, so I am asking what is the best way to prepare for such a thing? My domain is www.presentation.mydomain.com and I would like to keep this if possible (even if issues arise). I have been thinking of a few alternatives: Host my site on two different domains or servers (but what about the domain name?) Have a portable XAMPP version on a USB stick (again, domain name?) Possible failover site/location Update: The presentation will be carried out on their laptop, not mine. So I am unable to install any software.

• What is a good method for coloring textures based on a palette in XNA?

  - by Bob

  I've been trying to work on a game with the look of an 8-bit game using XNA, specifically using the NES as a guide. The NES has a very specific palette and each sprite can use up to 4 colors from that palette. How could I emulate this? The current way I accomplish this is I have a texture with defined values which act as indexes to an array of colors I pass to the GPU. I imagine there must be a better way than this, but maybe this is the best way? I don't want to simply make sure I draw every sprite with the right colors because I want to be able to dynamically alter the palette. I'd also prefer not to alter the texture directly using the CPU.

• Whats a good structure to save and retrieve locations of images?

  - by Goot

  I got a java-ee application, where I collect informations about movies. Im my backend I provide data like the name, description, genre and a random uuid. I also got lots of related files, which are stored on a file server. Including some screenshots, the dvd or bluRay cover and video trailers. My current approach is: When saving the files to the fileserver, I retrieve the movies random uuid (which is the primary key btw.). I then rename the files screenshot_[UUID]_1, screenshot_[UUID]_2 ... etc. Now, there are lots of other ways to handle this, like saving all filenames in a database or creating a dir structure on the fileserver for every uuid and, e.g., return all images in the "[uuid]/screenshots" folder via REST. I expect about 30k requests a day, so the service has to be pretty performant. Whats the best way to solve this?

• Tips for developing with a remote team

  - by mVChr

  My company has corporate offices around the country and I have been hired under contract to work in one office while the rest of my team works in another. We are in the same time zone, but definitely remote. I have not met the team yet, but will be flying up there soon. What is your best advice for integrating and developing with this team? What are the most important priorities? Standard versioning control, e-mail, phone, conference call and IM are all available resources, however Google apps, Skype and the like are not for security reasons.

• Multiple objects listening for the same key press

  - by xiaohouzi79

  I want to learn the best way to implement this: I have a hero and an enemy on the screen. Say the hero presses "k" to get out a knife, I want the enemy to react in a certain way. Now, if in my game loop I have a listener for the key press event and I identify a "k" was pressed, the quick and easy way would be to do: // If K pressed // hero.getOoutKnife() // enemy.getAngry() But what is commonly done in more complex games, where say I have 10 types of character on screen and they all need to react in a unique way when the letter "k" is pressed? I can think of a bunch of hacky ways to do this, but would love to know how it should be done properly. I am using C++, but I'm not looking for a code implementation, just some ideas on how it should be done the right way.

• Web api authentication techniques

  - by Steve

  We have a asp.net MVC web service framework for serving out xml/json for peoples Get requests but are struggling to figure out the best way (fast, easy, trivial for users coding with javascript or OO languages) to authenticate users. It's not that our data is sensitive or anything, we just want users to register so we can have their email address to notify them of changes and track usage. In our previous attempt we had the username in the URI and would just make sure that username existed and increment db tables with usage. This was super basic but we'd notice people using demo as a username etc so we need it to be a little more sophisticated. What authentication techniques are available? What do the major players use/do.

• Animating isometric sprites

  - by Mike

  I'm having trouble coming up with a way to animate these 2D isometric sprites. The sprites are stored like this: < Game Folder Root /Assets/Sprites/< Sprite Name /< Sprite Animation /< Sprite Direction /< Frame Number .png So for example, /Assets/Sprites/Worker/Stand/North-East/01.png Sprite sheets aren't really viable for this type of animation. The example stand animation is 61 frames. 61 frames for all 8 directions alone is huge, but there's more then just a standing animation for each sprite. Creating an sf::Texture for every image and every frame seems like it will take up a lot of memory and be hard to keep track of that many images. Unloading the image and loading the next one every single frame seems like it will do a lot of unnecessary work. What's the best way to handle this?

• Programming *into* a language vs. writing C code in Ruby

  - by bastibe

  Code Complete states that you should aways code into a language as opposed to code in it. By that, they mean Don't limit your programming thinking only to the concepts that are supported automatically by your language. The best programmers think of what they want to do, and then they assess how to accomplish their objectives with the programming tools at their disposal. (chapter 34.4) Doesn't this lead to using one style of programming in every language out there, regardless of the particular strengths and weaknesses of the language at hand? Or, to put the question in a more answerable format: Would you propose that one should try to encode one's problem as neatly as possible with the particulars of one's language, or should you rather search the most elegant solution overall, even if that means that you need to implement possibly awkward constructs that do not exist natively in one's language?

• Which office suite is the ideal alternative to MSOffice?

  - by user64720

  Let's say I want to drop MSOffice permanently and switch to a free alternative, not having the need of opening the documents on other PC's except my own (I can also carry a portable version on a pendrive and edit the docs anywhere). I know 3 free office suites - LibreOffice, Abiword and Calligra. Which one of these is the most complete and provides the best features to be a viable alternative to MSOffice, without compromising the quality of the work I can produce on Office apps? Notice that I'm not focusing the question on compatibility between MSOffice and other suites but instead I am comparing their quality, taking in comparison MSOffice.

• When to update jQuery?

  - by epaulk

  When you recommend updating jQuery/jQuery UI? Or in other words: what are the best practices for updating jQuery/jQuery UI? I’m working on a long project that will take at least one more year. In that time span, I’m sure that jQuery/jQuery UI will be updated many times. Do you recommend update my jQuery/jQuery UI files every time an update is released? Or is better to stick with a particular version until the end of the project? I’m afraid of “breaking” code changes, and every time an update is released, I have to test everything. That takes too much time. But on the other hand, if I didn’t update, I’m afraid of bugs that later will bite me in the rear. The project is an ASP.MVC and I use jQuery a lot. Any thoughts?

• Sortable Accordion Modified to Implement More On Click However New Levels Will Not Expand

  - by Tim Marshall

  JS Fiddle: http://jsfiddle.net/JF7PD/ I've been doing extensive work on this and I've just able almost got it fully working. The reason why I am asking for help now is that I don't have a clue why my newly added accordion(s) do not expand upon being clicked. I've got a feeling it may be due to the newly added code as I was having problems using my code in the file so instead I looked at the source and copied the accordion level to be used and all appears to look fine apart from them not expanding. Thank you for any help in advanced, Best Regards, Tim

• how to really master a programming language

  - by cprogcr

  I know that learning a language, you can simply buy a book, follow the examples, and whenever possible try the exercises. But what I'm really looking is how to master the language once you've learned it. Now I know that experience is one major factor, but what about learning the internals of the language, what is the underlying structure, etc. There are articles out there saying read this book, read that book, make this game and that game. But to me this doesn't mean to master a language. I want to be able to read other people's code and understand it, no matter how hard that is. To understand when to use a function and when another, etc etc. The list could go on and on but I believe I've made the point. :) And finally, take whatever language as an example if needed, though best would be if C was taken as an example.

• What to learn for a pure practical developer to get better?

  - by ChrisRamakers

  I'm a self taught developer that currently has more than enough experience to hold up against my colleagues waving with their degrees, yet I feel that I'm lacking some important skills to advance further into being a senior level professional in a leading role. More specific in the engineering, planning and designing aspect of software. I've touched the surface of UML, ERM/ERD, have experienced both waterfall and scrum projectmanagement, ... yet I feel there is something missing as every time I start on a new project I don't know where to begin. Should I start diagramming and how? should I start writing an xx page document describing the project on a technical level first, should I dive head first into writing the first tests and code or pseudo-code? I would like to know what, in my case, would be the best way forward, to learn how I can tackle this problem in the future and get better at leading and starting a project. There is not much i don't know about my technical tools and languages but when it gets abstract i'm in trouble.

  This question already has an answer here: Where can I go to find a game graphic artist? [on hold] 4 answers If I am making an amateur video game team to design and produce a project, where would I go to find someone to make 3D models? So far, I have my own story design and programming, someone doing engine programming, someone doing the sound, and someone possibly doing texture design. However, there is no one creating meshes. What would be the best course of action to find help?

• What is a light-weight "slideshow" script that could integrate w/ CMS?

  - by aslum

  I'm looking to reduce the footprint of my Strict html 4.01 front page. One possible way is to combine much of the "upcoming events" into a single small box, and have them automagically switch which one is displayed every few seconds. I'm sure there are a bunch of this kind of thing written already, and surely an open source one exists, but I haven't had much luck find one. I'd prefer javascript to jQuery as installing jQuery might not be an option, but if the best-fit script requires jQuery I'd certainly be willing to investigate that route. If it can display content from Wordpress that would be ideal.

• Introducing Task-It. A real-world application using RadControls for Silverlight 4

  This is the first in a series of blog posts based around an application called Task-It that I have developed in Silverlight 4. Task-It is real-world application designed for people that need a simple way to manage the numerous tasks that we all strive to accomplish on a daily basis. Figure 1: Task-It Tasks page Figure 2: Task-It Dashboard page I have developed this application for several reasons: There are many task management applications out there, and I have used quite a few of them, but I havent found one that really grabbed me. Many of these applications had their strong points,but some were overly complex, some lacked key features, some cost too much money, and so forth. I thought it would be nice to identify the best parts of each, and take my stab at building my own. During my evaluation of task management applications, I have not yet ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Open .doc file from my website in browser

  - by seth

  What's the best way to give the end-user of my web application the ability to open, edit and save (via browser) word documents that are stored in my database? I have this working by doing an html conversion of the file (via Aspose Words) but this method seems not even close to flawless and i'm trying to improve this. Is integrating with google docs possible/good? Their edition seems awesome and very powerful. I can't use any Microsoft Word objects (and this is even discouraged by MS). EDIT: The application is developed in .NET and currently uses the .NET framework 2.0. However, as this is fairly obsolete the idea is to restart from scratch and therefore use the 4.0 framework and C# or VB.

• Webcast: SANS Institute Product Review of Oracle Identity Manager 11gR2

  - by B Shashikumar

  Translating the IT-centric, directory based view of access and authorization into the process-driven concerns of business users inevitably creates unique challenges.

• Create Adventure Game Scene/Room/Backdrop from Real Photo

  - by Lyuben

  Is there a suitable software or a good tutorial for creating 2D rooms/scenery for adventure games from real photos? Is it possible to achieve good results by using photos, or the hand-drawn style will always be the best choice? Thank you! --- EDIT --- I want to clarify that I'm particularly interested in the art creation process, not on the environment in which to build games. I'm writing the game in Java for Android, but I don't think it matters. Also, I'm not trying to decide if the game will have photo realistic rooms or not - I want to achieve 2d pixelated, old-school style background scenes and I wonder if this can be made from photos, because I cannot draw them myself. For example, can I shoot a scene with my camera and then make it look something like the image in the following link: PIXEL ART FOREST I know that I cannot get the same quality as an absolutely hand-drawn pixel, but I'm looking for some decent technology/tutorial/software to make them somewhat similar.
