• graphic error on console

  - by Christian Elsner

  I have Linux on an embedded system. There is no graphic system, but I still have graphic errors. For example, if I type: ifconfig eth2 hw ether 00:0e:8c:d0:59:d2 I see: ifconfig eth hw ether 00:0e:8:2:2 If I type Enter, it accepts the command I typed, so it's just a matter of displaying. Everything is fine, when I log in via SSH. Anyone any ideas, what could be the cause or where to look at?

• Graphic Setup tune-up checklist

  - by Click Ok

  I was trying to play the game Warzone 2100 and the games runs fine, with nice speed, but the screen stays with a horizontal lines "flickering"... My PC have a integrated GeForce Go 6100 vga. Ok, not a powerfull vga, but it's not the end of the world to run a "simple" game like this (compared with another games that ask you send your eyes to purchase a expensive vga). So, I think that the problem can be of the configuration of my machine. I use it in first instance for programming jobs, so I underpay attention to video setup. I would like about a checklist to know if my PC is "ready" to games. By example, I know that I need: Lastest vga drivers Updated DirectX and OpenGL What you suggest? There is too some good programs to test performance and suggests improvements in the system? Thank you! PS: I'm using Windows 7

• Has anyboy been able to install Pantograph for Blender on Windows?

  - by S.gfx

  I am specially interested on if somebody is actually doing/maintaining an installer for Windows, as there are quite several issues when installing all dependencies, etc. (for example, there might be someone already doing a Installbuilder installer for it and am just not aware of the matter) If not, at least if someone got it working and has some key tip to share. I am never able to fully get it all up and running. I'd love to have a not super complex way to install each new build of this great vector rendering module for Blender.

• How to rotate attached monitor to notebook of Sony's Z-series?

  - by user67175

  Is it possible that Sony is selling a top of the line, hugely expensive computer that does not have the basic ability to rotate an attached monitor? Is it possible that the Z-series simply can't do this? The Windows control panel is missing the normal option for "rotation", as is the Nvidia control panel for "orientation" , no additional rotation software works. Sony sales says they do not know the answer to this. Sony technical supports says that the problem lies with Nvidia, Nvidia technical supports says the problem lies with Sony. Any advice for a fix for this short of returning the computer would be greatly appreciated. Also wondering if this problem is common to computers running Windows 7?

• Form graphics not set when form loads

  - by Jimmy

  My form has a group box which contains two overlapping rectangles. The form's other controls are two sets of four numeric up down controls to set the rectangles' colors. (nudF1,2,3 and 4 set the rectangle that's in front, and nudB1,2,3 and 4 set the rectangle that's behind.) Everything works fine, except that the rectangles do not display the colors set in the numeric up downs when the form first loads. The numeric up down controls' ChangeValue events all call the ShowColors() method. The form's Load event calls the csColorsForm_Load() method. Any suggestions? namespace csColors { public partial class csColorsForm : Form { public csColorsForm() { InitializeComponent(); } private void csColorsForm_Load(object sender, EventArgs e) { this.BackColor = System.Drawing.Color.DarkBlue; SetColors(sender, e); } private void SetColors(object sender, EventArgs e) { Control control = (Control)sender; String ctrlName = control.Name; Graphics objGraphics; Rectangle rect1, rect2; int colorBack, colorFore; objGraphics = this.grpColor.CreateGraphics(); // If calling control is not a forecolor control, paint backcolor rectangle if (ctrlName.Substring(0,4)!="nudF") { colorBack = int.Parse(SetColorsB("nudB"), NumberStyles.HexNumber); SolidBrush BrushB = new SolidBrush(Color.FromArgb(colorBack)); rect1 = new Rectangle(this.grpColor.Left, this.grpColor.Top, this.grpColor.Width, this.grpColor.Height); objGraphics.FillRectangle(BrushB, rect1); } // Always paint forecolor rectangle colorFore = int.Parse(SetColorsB("nudF"), NumberStyles.HexNumber); SolidBrush BrushF = new SolidBrush(Color.FromArgb(colorFore)); rect2 = new Rectangle(this.grpColor.Left, this.grpColor.Top, this.grpColor.Width, this.grpColor.Height); objGraphics.FillRectangle(BrushF, rect2); objGraphics.Dispose(); } private string SetColorsB(string nam) { string txt=""; for (int n = 1; n <= 4; ++n) { var ud = Controls[nam + n] as NumericUpDown; int hex = (int)ud.Value; txt += hex.ToString("X2"); } return txt; } private void btnClose_Click(object sender, EventArgs e) { this.Close(); } } }

• Making a Web Gui to design a Garden Layout

  - by paddydub

  I would like to design a web page Gui where users can design a simple interactive garden. The user would pick a template design and receive price estimates based on the design template and the dimensions entered. I'd like the user to be able to move items such as plants, stones and be able to adjust the dimensions of the grass, paving. I'm thinking i could make it using flash but I would like to know there are any other ways I could use to implement this?

• What design pattern will you choose ?

  - by MemoryLeak

  I want to design a class, which contains a procedure to achieve a goal. And it must follow some order to make sure the last method, let's say "ExecuteIt", to behave correctly. in such a case, what design patter will you use ? which can make sure that the user must call the public method according some ordering. If you really don't know what I am saying, then can you share me some concept of choosing a design patter, or what will you consider while design a class?

• Game planning and software design? I feel that UML is not convenient

  - by user1542

  In my university, they always emphasize and hype about UML design and stuff, in which I feel it is not going to work well with game structure design. Now, I just want a professional advice on how should I begin my game designing? The story is I have some skill in programming and have done many minor game such as getting some 2D platformer working to some extend. The problems that I find about my program is the poor quality design. After coding for a while, things start to break down due to poor planning (When I add new feature, it tends to make me have to recode the whole program). However, to plan everything out without a single design flaw is a bit too ideal. Therefore, any advice to how should I plan my game? How should I put it into visible pictures, so that me and my friends are able to overview the designs? I planned to start coding a game with my friend. This is going to be my first teamwork, so any professional advices would be a pleasure. Is there any other alternatives than UML? Another question is how does "prototyping" normally looks like?

• Need design ideas generators.

  - by Clubspy

  Hello guys I am a web developer and sometimes I have to do some design myself for my customers but design actually is not my best thing to do. I am looking for a program that can help me getting fast and reliable design ideas but I am not looking for code generator like Artisteer. Actually design is a hard task and my designs always look ugly and messy.

• Suggestions for opening the Rails toolbox to design a challenge game?

  - by keruilin

  How would you suggest designing a challenge system as part of a food-eating game so that it's automated as possible? All RoR tools, design patterns and logic are at your disposal (e.g., admin consoles, crontab, arch, etc.). Prize goes to whoever can suggest the simplest and most-automated design! Here are the requirements: User has many challenges. Badge has many challenges. (A unique badge is awarded for each challenge won.) Only one challenge can run at a time. Each challenge has a limited number of days that it runs. For example, one challenge can run 3 days, while another runs 7 days. Challenges can be seasonal. For example, "Eat 13 Pumpkins" only runs during the Fall. New challenges are added to the game on an ongoing basis. For example, a new challenge every week. Each challenge has a certain probability of being selected to run. For example, "Eat 10 Pies" challenge has 10% chance of being selected to run. As each new challenge is added to the database, I want the probabilities of running to change dynamically. I want to avoid the scenario where I'm manually updating a database field just to change the probability from 10% to 5%, for example. Challenges act like Easter eggs. Challenge icons pop-up at different places on the webpage. User is awarded a badge for successfully completing a challenge, but only when it's active. There is some wait time between each challenge. Between 1 and 7 days. Which wait time is random, but the probability of the wait time being short is high and the probability of it being a long wait time is low.

• What makes my code DDD (domain-driven design) qualified?

  - by oykuo

  Hi All, I'm new to DDD and am thinking about using this design technique in my project. However, what strikes me about DDD is that how basic the idea is. Unlike other design techniques such as MVC and TDD, it doesn't seems to contain any ground breaking ideas. For example, I'm sure some of you will have the same feeling that the idea of root aggregates and repositories are nothing new because when you are was writing MVC web applications you have to have one single master object (i.e. the root aggregate) that contain other minor objects (i.e. value objects and entities) in the model layer in order to send data to a strongly typed view. To me, the only new idea in DDD is probably the "Smart" entities (i.e. you are supposed to have business rules on root aggregates) Separation between value object, root aggregate and entities. Can anyone tell me if I have missed out anything here? If that's all there is to DDD, if I update one of my existing MVC application with the above 2 new ideas, can I claim it's an TDD, MVC and DDD applcation?

• Software or Photoshop plugins for professional photo album design

  - by Iain Fraser

  I am a graphic designer (among other things) and I'm used to doing magazine advertisements, brochures, posters and that sort of thing. Recently I was approached by a photographer who wants a graphic designer to produce wedding albums for him. I have already done a couple for him but I'm finding it hard to work by just arranging my layouts in Photoshop alone. It's very time consuming, but quite repetitive - especially when you're dealing with common page layouts. I know a lot of photographers use album design software to speed up the process a bit. What's the industry standard in terms of album design software?

• Design Pattern Books, Papers or Resources for Non-Object Orientated Paradigms?

  - by FinnNk

  After viewing this video on InfoQ about functional design patterns I was wondering what resources are out there on design patterns for non-object orientated paradigms. There are plenty out there for the OO world (GOF, etc, etc) and for architecture (EoEAA, etc, etc) but I'm not aware of what's out there for functional, logic, or other programming paradigms. Is there anything? A comment during the video suggests possibly not - does anyone know better? (By the way, by design patterns I don't mean language features or data structures but higher level approaches to designing an application - as discussed in the linked video)

• Should I use the factory design pattern for every class?

  - by Frog

  I've been writing a website in PHP. As the code becomes more complex, I keep finding problems that can be solved using the factory design pattern. For example: I've a got a class Page which has subclasses HTMLPage, XMLPage, etc. Depending on some input I need to return an object of either one of these classes. I use the factory design pattern to do this. But as I encounter this problem in more classes, I keep having to change code which still initiates an object using its constructor. So now I'm wondering: is it a good idea to change all code so that it uses the factory design pattern? Or are there big drawbacks? I'm currently in a position to change this, so your answers would be really helpful.

• Is the structure used for these web pages a design pattern?

  - by aspdotnetuser

  I want to know if the structure for an ASP.NET website I'm working on uses a design pattern for it's web pages. If it is a design pattern, what is it called? The web pages have the following structure: UserDetails page (UserDetails.aspx) - includes UserDetailsController.ascx user control. UserDetailsController.ascx includes sub user controls like UserAccountDetails.ascx and UserLoginDetails.ascx etc Each sub user control contains a small amount of code/logic, the 'controller' user controls that host these sub user controls (i.e UserDetailsController.ascx) appear to call the business rules code and pass the data to the sub user controls. Is this a design pattern? What is it called?

• How do you enhance your websites speed without compromising the design and access?

  - by Thorn007

  How do you enhance your websites load speed without killing the design and accessibility? File compression, CDN, Gzip? What are the best tools for doing so? For example, Google has optimized their site without compromising the design. Also, many website can kill the purity of their images with compression. Is there a way, more or lest best practice, to increase speed without compromising the design and accessibility? Note: sorry for being so vague but I don't know how else to phrase this question.

• Where should I ask for feedbacks about web design? [closed]

  - by mariosangiorgio

  Possible Duplicate: Where can I get my website critiqued I am developing my personal website and I'd like to have feedbacks about its design. Is there any site/forum you would recommend me? I know that the best solution would be to hire a professional web designer and have him design my website, but I am also interested in understanding how to improve my design skills. Of course any recommended book, website, resource is more than welcome. I am not posting here the link to my home page because I think this Q/A site is more about web-development in general, but if you'd like to see my personal page and give some feedback I'll link it.

• Do you know any examples of a PAC design pattern?

• When can a design pattern make your software worse?

  - by magol

  When can a design pattern make your software worse? I have seen a program where they used the facade pattern between the GUI and logic. They considered that no objects may be transported over this, so only primitive types were used which made it difficult to code.

• Design of Business Layer

  - by Adil Mughal

  Hi, We are currently revamping our architecture and design of application. We have just completed design of Data Access Layer which is generic in the sense that it works using XML and reflection to persist data. Any ways now we are in the phase of designing business layer. We have read some books related to Enterprise Architecture and Design so we have found that there are few patterns that can be applied on business layer. Table Pattern and Domain Model are example of such patterns. Also we have found Domain Driven Design as well. Earlier we decided to build Entities against table objects. But we found that there is difference in Entities and Value Objects when it comes to DDD. For those of you who have gone through such design. Please guide me related to pattern, practice and sample. Thank you in advance! Also please feel free to discuss if you didn't get any point of mine.

• What design pattern do you use the most?

  - by spoon16

  I'm interested in understanding what design patterns people find themselves using often. Hopefully this list will help other recognize common scenarios and the associated design pattern that can be used to solve them. Please describe a common problem you find yourself solving and the design pattern(s) you use to solve it. Links to blogs or documentation describing the pattern are also appreciated. Edit: Please expand on your answers a bit, I would like this to be a useful reference for someone who wants to learn more about design patterns and is curious on what situations a specific design pattern might be used. Nobody has linked to any "more learning" resources.

• is it good design practice to only have a parameterless base class constructor?

  - by T. Webster

  In base class constructors I always see a parameterless constructor, like so: public abstract BaseClass {... protected BaseClass() { } ...} but is it acceptable design to include a parameter in the base class constructor? public abstract BaseClass {... protected BaseClass(string initObj) { } ...}

• Documenting a policy based design

  - by academicRobot

  I'm re-working some prototype code into a policy based design in C++, and I'm wondering what the best practice is for documenting the design. My current plan is to document: Policy hierarchy Overview of each policy Description of each type/value/function in each policy I was thinking of putting this into a doxygen module, but this looks like it will be a bit awkward since formatting will have to be done by hand without code to base the doc on (that is, documenting the policies rather than the implementation of the policies). So my questions are: Are there other aspects of the design that should be documented? Are there any tricks to doing this efficiently in doxygen? Is there a tool other than doxygen thats better suited to this? What are some examples of well documented policy based design? This is my first serious attempt at policy based design. I think I have a working grasp of the principles, but whatever naivety I expose in this question is fair game for an answer too.

• Analysis and Design for Functional Programming

  - by edalorzo

  How do you deal with analysis and design phases when you plan to develop a system using a functional programming language like Haskell? My background is in imperative/object-oriented programming languages, and therefore, I am used to use case analysis and the use of UML to document the design of program. But the thing is that UML is inherently related to the object-oriented way of doing software. And I am intrigued about what would be the best way to develop documentation and define software designs for a system that is going to be developed using functional programming. Would you still use use case analysis or perhaps structured analysis and design instead? How do software architects define the high-level design of the system so that developers follow it? What do you show to you clients or to new developers when you are supposed to present a design of the solution? How do you document a picture of the whole thing without having first to write it all? Is there anything comparable to UML in the functional world?
