  • How can I design good continuous (seamless) tiles?

    - by Mikalichov
    I have trouble designing tiles so that when assembled, they don't look like tiles, but look like a homogeneous thing. For example, see the image below: Even though the main part of the grass is only one tile, you don't "see" the grid; you know where it is if you look a bit carefully, but it is not obvious. Whereas when I design tiles, you can only see "oh, jeez, 64 times the same tile," like in this image: (I took this from another GDSE question, sorry; not be critical of the game, but it proves my point. And actually has better tile design that what I manage, anyway.) I think the main problem is that I design them so they are independent, there is no junction between two tiles if put closed to each other. I think having the tiles more "continuous" would have a smoother effect, but can't manage to do it, it seems overly complex to me. I think it is probably simpler than I think once you know how to do it, but couldn't find a tutorial on that specific point. Is there a known method to design continuous / homogeneous tiles? (My terminology might be totally wrong, don't hesitate to correct me.)

  • Learning good OOP design & unlearning some bad habits

    - by Nick
    I have been mostly a C programmer so far in my career with knowledge of C++. I rely on C++ mostly for the convenience STL provides and I hardly ever focus on good design practices. As I have started to look for a new job position, this bad habit of mine has come back to haunt me. During the interviews, I have been asked to design a problem (like chess, or some other scenario) using OOP and I doing really badly at that (I came to know this through feedback from one interview). I tried to google stuff and came up with so many opinions and related books that I don't know where to begin. I need a good through introduction to OOP design with which I can learn practical design, not just theory. Can you point me to any book which meets my requirements ? I prefer C++, but any other language is fine as long as I can pick-up good practices. Also, I know that books can only go so far. I would also appreciate any good practice project ideas that helped you learn and improve your OOP concepts. Thanks.

  • Learn Behavior-Driven Development

    - by Ben Griswold
    In this presentation, I provided a brief introduction into TDD and talked about the confusion and misconceptions around the discipline. I, of course, shared a bit about Dan North, the father of BDD and touched upon some crazy hypothesis dreamed up by Sapir and Whorf. I then gave a Behavior Driven Development overview (my impressions of the implementation and lifecycle) and then touched upon available tools, how to get started and I threw in a number of reference and reading materials which you will find below. As an added bonus, I demonstrated how easy it is to include/exclude hyphens and alter the spelling of “behavior” at will.   Introducing BDD, Dan North Oredev 2007 – Behaviour-Driven Development, Dan North Behavior-Driven Development, Scott Bellware Behavior Driven Development, Wikipedia BDD Wiki A New Look at Test-Driven Development, Dave Astels Behavior Driven Development – An Evolution in Testing, Bob Cotton The Truth about BDD, Uncle Bob Martin Language and Thought, Wikipedia Sapir-Whorf Hypothesis, Wikipedia What’s in a Story?, Dan North

  • Level Design V.S. Modeler

    - by Ecurbed
    From what I understand being a level designer and a character/environment/object/etc Modeler are two different jobs, yet sometimes it feels like a Modeler can also do the job of the level designer. I know this also depends on the scale of the game. For small games maybe they are one and the same, but for bigger games they become two different jobs. I understand a background in some modeling could not hurt when it comes to level design, but the question I have is: Do jobs prefer people who can model for level designing? This way they can kill two birds with one stone and have someone to create the assets and design the level. What is your opinion of the training? Does level design contain skill sets that make them completely different from what a modeler can do, or is this an easy transition for a modeler to become a level designer? Can you be a bad level designer but a good modeler and vice versa?

  • How to design network protocols

    - by dandroid
    As a programmer, you work on your software design skills. You learn about things such as modularity and reusability and how you can achieve them in code. There's plenty of literature on the subject and engineers talk about it all the time. What about if you want to design network protocols? How do you judge that protocol X is badly designed while Y is well designed? (eg. in programming you are often pointed out to a well-written piece of code in order to learn from it - what is the equivalent for network protocols?) For example, suppose I want to design a P2P protocol similar to BitTorrent or I want to make a better version of the Socks protocol. How would I go about doing a good job on this? Thanks!

  • Green Website Design

    - by Christofian
    This is kindove a strange question, but... There was a site called Blackle ( http://www.blackle.com/) which "claimed" to save energy by using a black background (it doesn't: see here: http://skeptics.stackexchange.com/questions/4373/how-much-energy-does-displaying-a-webpage-with-a-black-background-actually-save). However, blackle and it's idea of "green website design" interested me, and I was wondering if there are any ways to design an energy saving website that actually save energy. If anyone knows of any, please post them here. If nobody has any, then I guess there isn't a way to save energy through website design...

  • Right multi object dependance design

    - by kenny
    I need some help with a correct design. I have a class called BufferManager. The push() method of this class reads data from a source and pushes it to a buffer repeatedly until there is no more data left in the source. There are also consumer threads that read data from this buffer, as soon as new data arrives. There is an option to sort the data before it comes to buffer. What I do right now is that BufferManager, instead of pushing data to the buffer, pushes it to another "sorting" buffer and starts a sorting thread. SorterManager class reads the data, sorts it in files and push()es the sorted data into the buffer. There will be a bottleneck (I use merge sort with files) but this is something I can't avoid. This is a bad design, because both BufferManager and SorterManager push data to a buffer (that consumers read from). I think only BufferManager should do it. How can I design it?

  • Software Architecture - From design to sucessful implementation

    - by user20358
    As the subject goes; once a software architect puts down the high level design and approach to a software that is to be developed from scratch, how does the team ensure that it is implemented successfully? To my mind the following things will need to be done Proper understanding of requirements Setting down coding practices and guidelines Regular code reviews to ensure the guidelines are being adhered to Revisiting the requirements phase and making necessary changes to design based on client inputs if there are any changes to requirements Proper documentation of what is being done in code Proper documentation of requirements and changes to them Last but not the least, implementing the design via object oriented code where appropriate Did I miss anything? Would love to hear any mistakes that you have learned from in your project experiences. What went wrong, what could have been done better. Thanks for taking the time..

  • Is it possible to outsource design properly?

    - by Eric
    I work in a company going through a downsizing process. It is assumed that a lot of "let go" developers jobs will eventually be outsourced. Some of those programmers had some design to do. Is it possible to outsource both design and creation/coding properly? I feel that by outsourcing design, we lose any in-house capability of really "owning" the code. It will be very difficult to maintain. Also we'll have a hard time ensuring a proper development. How can I address those issues?

  • Most appropriate diagram for GUI button design?

    - by JustADude
    What is the most appropriate diagram for GUI button design? Specifically, I have numerous buttons that will be changing color based on state information from operator input and input from various subcomponents and sensors. I would like to use UML or some other type of design diagrams to be able to capture the color transition. Some folks have suggested sequence diagrams, but I haven't been able to find any good examples that show how to incorporate this design artifact. I would really like to head in this direction to help developers. Thanks a ton for feedback and insights.

  • Should we design programs to randomly kill themselves?

    - by jimbojw
    In a nutshell, should we design death into our programs, processes, and threads at a low level, for the good of the overall system? Failures happen. Processes die. We plan for disaster and occasionally recover from it. But we rarely design and implement unpredictable program death. We hope that our services' uptimes are as long as we care to keep them running. A macro-example of this concept is Netflix's Chaos Monkey, which randomly terminates AWS instances in some scenarios. They claim that this has helped them discover problems and build more redundant systems. What I'm talking about is lower level. The idea is for traditionally long-running processes to randomly exit. This should force redundancy into the design and ultimately produce more resilient systems. Does this concept already have a name? Is it already being used in the industry?

  • UML Class Diagram for User Login

    - by 01010011
    Hi, The diagram below is my very first attempt at creating a UML class diagram describing a user login into a website. I'm sure its a poor design and full of flaws, but I'm hoping to learn from you guys how you would design a simple login like this. I'm particularly interested in your use of design patterns and which patterns you would use, how you would implement it in the design, and why. Any advise, criticisms, comments and suggestions will be really appreciated. Thanks in advance.

  • Application Design: Single vs. Multiple Hits to the DB

    - by shyneman
    I'm building a service that performs a set of configured activities based on the type of request that it receives. Each activity involves going to the database and retrieving/updating some kind of information. The logic for each activity can be generalized and re-used across different request types. The activities may need to participate in a transaction for the duration of the servicing the request. One option, I'm considering is having each activity maintain its own access to DAL/database. This fully encapsulates the activity into a stand-alone re-usable piece, but hitting the database multiple times for one request doesn't seem like a viable option. I don't really know how to easily implement the concept of a transaction across the multiple activities here either. The second option is to encapsulate ALL the activities into one big activity and hit the database once. But this does not allow re-use and configuration of these activities for different requests. Does anyone have any suggestions and input about what should be the best way to approach my problem? Thanks for any help.

  • How to extend this design for a generic converter in java?

    - by Jay
    Here is a small currency converter piece of code: public enum CurrencyType { DOLLAR(1), POUND(1.2), RUPEE(.25); private CurrencyType(double factor) { this.factor = factor; } private double factor; public double getFactor() { return factor; } } public class Currency { public Currency(double value, CurrencyType type) { this.value = value; this.type = type; } private CurrencyType type; private double value; public CurrencyType getCurrencyType() { return type; } public double getCurrencyValue() { return value; } public void setCurrenctyValue(double value){ this.value = value; } } public class CurrencyConversion { public static Currency convert(Currency c1, Currency c2) throws Exception { if (c1 != null && c2 != null) { c2.setCurrenctyValue(c1.getCurrencyValue() * c1.getCurrencyType().getFactor() * c2.getCurrencyType().getFactor()); return c2; } else throw new Exception(); } } I would like to improve this code to make it work for different units of conversion, for example: kgs to pounds, miles to kms, etc etc. Something that looks like this: public class ConversionManager<T extends Convertible> { public T convert(T c1, T c2) { //return null; } } Appreciate your ideas and suggestions.

  • Implementing Domain Driven Design

    - by Steve Dunn
    Is anyone using the techniques from Domain Driven Design? I've recently read the Eric Evans book of the same name (well, most of it!) and would be interested to hear from anyone who's implemented all/some of it in a project (particularly in C#/C++) I've kept this question open ended as I'd like to see as many comments as possible, but I have a few questions in particular: 1 - Should value types be real 'value types' if the language supports it? e.g. a struct in C# 2- Is there any feature in C# that makes clearer the association between the language and the model (for instance, this is an entity, this is an aggregate etc.)

  • Normalized class design and code first

    - by dc7a9163d9
    There are the following two classes. public class Employee { int EmployeeId { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public string Street { get; set; } public string Street2 { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } } public class Company { int CompanyId { get; set; } public string Name { get; set; } public string Street { get; set; } public string Street2 { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } } In a DDD seminar, the speaker said the better design should be, class PersonName { public string FirstName { get; set; } public string LastName { get; set; } } class Address { public string Street { get; set; } public string Street2 { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } } public class Employee { int EmployeeId { get; set; } public PersonName Name { get; set; } [ForeignKey("EmployerAddress")] public int EmployerAddressId { get; set; } public virtual Address EmployerAddress { get; set; } } public class Company { int CompanyId { get; set; } public string Name { get; set; } [ForeignKey("CompanyAddress")] public int CompanyAddressId { get; set; } public virtual Address CompanyAddress { get; set; } } Is it the optimized design? How the code first generate the PersonName table and link it to Employee?
