  • Software to Mind Map Dependencies

    - by Alix Axel
    I'm putting together something I'll soon release as OSS and I wanted to make a map of dependencies to get a clearer idea of the big picture. I ended up making the mind map myself using pen and paper: This is something I wish I could do more often, but mapping bigger projects manually is too troublesome (and virtually impossible due to the size of the sheet) and since I can't find any mind mapping software that fits my needs and allows me to display the map in the visual structure I want I often leave the mind maps in my mind alone, no visual representation whatsoever... Can anyone suggest a good mind mapping software that allows me to do something like the above? I've tried FreeMind and XMind so far but their visual structure is too rigid for what I need.

  • Voting software with remote units - architectural questions

    - by David Neale
    I'm looking at designing some software that registers live votes (let's say A,B,C or D). The vote needs to be picked up and processed by a .NET engine. The remote voting units should be as small as possible. What form of data transmission should be used for the voting? The data is obviously very simple but there is a need to make sure each unit can only vote once per question. How would the data be received by the computer running the software?

  • Want to develop my own primitive physics engine, don't know how to start with it's high-level architecture. Suggestions?

    - by Violet Giraffe
    Few years ago I tried to make a simple 3D game - billiards. Completed like 50%, stuck with physics. Basically, I only need to calculate balls rolling over flat surface, but it would be nice to make something more flexible. I know all the formulas and laws (most of them, anyway). the problem is I have no idea of how to make good physics engine architecture-wise. I tried google and other forums but didn't find what I was looking for. The only suggestion was to look at open-source engine, but I'm not that good a programmer to make heads or tails out of it...

  • Designing a system with different business rules for different customers

    - by user1595846
    My company is rewriting our proprietary business application. The current architecture is poorly done and inflexible. It is coded more procedural oriented as opposed to object oriented. It has become difficult to maintain. Our system is a web application written in .Net Webforms. I am considering ASP.Net MVC for the rewrite. We intend to rewrite it with a good, solid architecture with the goal of maintainability and reusable classes for some of our other systems and services. We would also like the system to be customizable for different customers in the event that we market the system. I am considering redesigning the system based on the layered architecture (Presentation, Business, Data Access layers) described in the Microsoft Patterns and Practices Application Architecture Guide. http://msdn.microsoft.com/en-us/library/ff650706.aspx Hopefully this isn't too open ended, but how would you recommend allowing for different business logic/rules for different customers? I'm aware of Windows Workflow Foundation, but from what I've read about it, it seems many business rules could be too complicated to handle there. Also, Can anyone point me to where I can download an example of a .net solution that is based on the Application Architecture Guide? I have already downloaded the Layered Architecture Solution Guidance and the Expense Sample on codeplex. I was looking for something a bit larger and more robust that I could step through the code and see how it works. If you feel there are better architectures to base our redesign on please feel free to share. I appreciate your help!

  • Enterprise VS Regular corporate developer

    - by Rick Ratayczak
    Ok, I "almost" lost a job offer because I "didn't have enough experience as an enterprise software engineer". I've been a programmer for over 16 years, and the last 12-14 professionally, at companies big and small. So this made me think of this question: What's the difference between a software engineer and an enterprise software engineer? Is there really a difference between software architecture and enterprise architecture? BTW: I try to do what every other GOOD software programmer does, like architecture, tdd, SDLC, etc.

  • Determing software estimates and tracking past estimates

    - by Casey
    I know that this probably has as many answers as users here on SO, but software estimation always seemed like an esoteric science. Software developers don't have a magic book to refer to as exist in many other industries. I've been spending the last couple of days working on putting together some estimates for a bit of work that I am proposing for a freelance project that I am working on and am having trouble getting it down. I'm not experienced with any real software estimation practices and am trying to go from the gut based on my experience but also trying to be a little loose (not too loose though) on the estimates to leave me a bit of room to work. I read this blog entry http://blogs.popart.com/2007/07/what-scotty-from-star-trek-can-teach-us-about-managing-expectations/ that was linked to from SO and would like to start tracking my estimates at work as well even though I'm not really required to create estimates there. What tools or techniques would you recommend? Also, how much padding do you usually add in to a time estimate?

  • Licencing: release the same software with double licence

    - by Luca
    In my free time, I develop (alone, sigh) a project, in particoular an application library. I've released it using GPL v3. At this time, this project has come very useful for a job. I'd like to release my OSS library toghether with the application using the same GPL v3 licence, with the exception that it can be linked for the specific application, or for the specific application vendor. AFAIK, the copyright owner can handle the entire source and licencing it, I did it; and probably the licence owner could cut&paste its own code, change its licence and use for other projects, isn't? But an GPL'ed library cannot be linked with a proprietary software, right? But software could be double-licenced, as MySQL does. So the question is: what should I do to allow the distribution of my GPL'ed library with a proprietary software, being the copyright owner?

  • Pitfalls to avoid when starting a software company.

    - by Imagist
    It's been my goal to start my own software company basically since I started programming HyperCard on System 6 back in elementary school. Recent changes in my job situation have convinced me that I should be pursuing this goal more actively. My question is, what are some pitfalls that I should avoid when starting a software company? A lot of companies fail and I'm sure there are a lot of reasons. As a side-request, it would be particularly helpful if you could tell me a little about your own experience with starting a software company or being a part of a startup, so I know how you know what you know.

  • Software Protection: Shuffeling my application?

    - by Martijn Courteaux
    Hi, I want to continue on my previous question: http://stackoverflow.com/questions/3007168/torrents-can-i-protect-my-software-by-sending-wrong-bytes Developer Art suggested to add a unique key to the application, to identifier the cracker. But JAB said that crackers can search where my unique key is located by checking for binary differences, if the cracker has multiple copies of my software. Then crackers change that key to make them self anonymous. That is true. Now comes the question: If I want to add a unique key, are there tools to shuffle (a kind of obfuscation) the program modules? So, that a binary compare would say that the two files are completely different. So they can't locate the identifier key. I'm pretty sure it is possible (maybe by replacing assembler blocks and make some jumps). I think it would be enough to make 30 to 40 shuffles of my software. Thanks

  • Experience using IRC to coordinate software development?

    - by momeara
    I am part of a growing software project with at least 200 active developer in 10 locations. I would like to set up an on-line chat forum for developers because I think it would help to coordinate efforts. We have an email mailing list but I feel like some questions or announcements are too informal to send to everyone while mentioning it in a chat forum might be a useful community resource. I have never participated in a software project that used an on-line chat forum so I would like to hear about peoples experiences. I am particularly interested in technical issues: Use of IRC vs. alternative platforms; how to manage access, eg. for developers only, allowing users to participate; the value of requiring certain announcements to be made on the chat forum eg who is resolving broken builds etc. If I pitch the idea to the community I would like to have some good arguments why it would be a good idea and some prospective of its usefulness in other software projects.

  • Most common software development mistakes

    - by hgulyan
    Inspired by Dealing with personal failure, I remembered my own failed software development experience. Finally I agreed to rewrite existing application. It took me less than a week to rewrite existing app and more up to 2 months to write from zero my own. That 2 months were really hard and interesting. It was my first big software development process. I researched almost everything concerning to my application. Read Code Complete. Even some articles on how to create user interface. Some psychology stuff. Typography, Colors. DAL, DB Structure, SOA, Patterns, UML, Load testing etc. I hope, that after a month or 2 I would get opportunity to continue working on my failed project, but before that, I would like to ask: What are common mistakes in software development? What you shouldn't do in any case?

  • Will you install software on the same partition as Windows system?

    - by Tim
    I was wondering if you always install software on the same partition as Windows 7 system? What kinds of software do you install on the same partition as Windows system? What kinds of software you install on another partition? If you install software on another partition, do you install them on a dedicated partition to these software? Or do you install them on the same partition as data (personal data)? How do you plan the sizes for the partition(s) in either case? What are to consider when making plans about the above questions? The software I am installing include: Matlab, Mathematica, IDEs, compilers or Interpreters for C++, C, Java, R, Python, Perl, Lisp, Latex, and database. Mainly for programming and typesetting kinds of studies and projects.

  • Cloud computing over Client-server: differences, cons and pros ?

    - by Vimvq1987
    As far as I know, Cloud computing might be a evolution in software architect, and it will replace some current architectures, such as client-server. These two architecture seem to share similarities for me (I know very little about both), but I don't know the differences between them. What are the cons and pros of cloud computing over client-server architecture? Thank you so much.

  • Initial Modelling/Design Activities on Agile Projects

    - by dalton
    When developing an application using agile techniques, what if any initial modelling/architecture activities do you do, and how do you capture that knowledge?? The closest thing I've seen so far is Scott Ambler's Initial Architecture Modelling, but was wondering what alternatives are used out there?

  • Is there a tool to do round trip software engineering between a sequence diagram and a group of objects that message back and forth?

    - by DeveloperDon
    Is there a tool to do round trip software engineering between a sequence diagram and a group of objects that message back and forth? Perhaps this seems a little exotic, but it seems like a function that includes message calls or even method invocations on other objects could be automatically converted to a sequence diagram given that it is not hard to do manually. Similarly, when a sequence diagram is modified, based on the message name and type of message, should it not be possible to add a message or method to the calling object?

  • What is better Ubuntu Tweak or Ubuntu Software center?

    - by S B
    Ubuntu Tweak has served me very well over the past few release cycles, but there seems to be more and more of an overlap between Ubuntu Tweak and the Ubuntu Software Center. I wanted to know whether these two great apps are headed for a head-to-head crash (which would be a shame for the Ubuntu community) or is there some way for the two projects to complement each other, integrate and make my favorite distribution even better? Happy new year to everyone.

  • How to process payments for a software (activation code)?

    - by jsoldi
    I want to sell software online and I need an easy to implement payment processing system. What I'm actually going to be selling is an activation code (one per purchase) that would activate the trial version of a product. I was about to use this one but I just found out that people without a paid email account (not hotmail or yahoo) can't process their orders, which I'm sure would discourage many, if not most, of the possible buyers.

  • What are the alternatives to fixed-price or time-and-materials contracts for software development?

    - by Fortuity
    Where can I learn more about pros/cons of various pricing models for software development? Proponents of agile methodology suggest approaches such as multi-stage contracts, target cost contracts, target schedule contracts, shared benefit contracts, variable scope contracts (http://poppendieck.com/agilecontracts.htm). I'm looking for opinions, experience, case studies or informed discussion of these approaches.

  • Why do we need different CPU architecture for server & mini/mainframe & mixed-core?

    - by claws
    Hello, I was just wondering what other CPU architectures are available other than INTEL & AMD. So, found List of CPU architectures on Wikipedia. It categorizes notable CPU architectures into following categories. Embedded CPU architectures Microcomputer CPU architectures Workstation/Server CPU architectures Mini/Mainframe CPU architectures Mixed core CPU architectures I was analyzing the purposes and have few doubts. I taking Microcomputer CPU (PC) architecture as reference and comparing others. Embedded CPU architecture: They are a completely new world. Embedded systems are small & do very specific task mostly real time & low power consuming so we do not need so many & such wide registers available in a microcomputer CPU (typical PC). In other words we do need a new small & tiny architecture. Hence new architecture & new instruction RISC. The above point also clarifies why do we need a separate operating system (RTOS). Workstation/Server CPU architectures I don't know what is a workstation. Someone clarify regarding the workstation. As of the server. It is dedicated to run a specific software (server software like httpd, mysql etc.). Even if other processes run we need to give server process priority therefore there is a need for new scheduling scheme and thus we need operating system different than general purpose one. If you have any more points for the need of server OS please mention. But I don't get why do we need a new CPU Architecture. Why cant Microcomputer CPU architecture do the job. Can someone please clarify? Mini/Mainframe CPU architectures Again I don't know what are these & what miniframes or mainframes used for? I just know they are very big and occupy complete floor. But I never read about some real world problems they are trying to solve. If any one working on one of these. Share your knowledge. Can some one clarify its purpose & why is it that microcomputer CPU archicture not suitable for it? Is there a new kind of operating system for this too? Why? Mixed core CPU architectures Never heard of these. If possible please keep your answer in this format: XYZ CPU architectures Purpose of XYZ Need for a new architecture. why can't current microcomputer CPU architecture work? They go upto 3GHZ & have upto 8 cores. Need for a new Operating System Why do we need a new kind of operating system for this kind of archictures?
