  • Can I use the test suite from an open source project to verify that my own 'compatible library' is compatible?

    - by Mark Booth
    The question Is it illegal to rewrite every line of an open source project in a slightly different way, and use it in a closed source project? makes me wonder what would be considered a clean-room implementation in the era of open source projects. Hypothetically, if I were to develop a library which duplicates the publicly documented interface of an open-source library, without ever looking at the source code for that library, could that code ever be considered a derivative work? Obviously it would need the same class hierarchy and method signatures, so that it could be a drop-in replacement - could that in itself, be enough to provoke a copyright claim? What about if I used the test suite of the open source project to verify whether my clean implementation behaved in the same way as the original library? Would using the test suite be enough to dirty my clean code? As should be expected from a question like this, I am not looking for specific legal advice, but looking to document experiences people may have had with this sort of issue.

  • What is the best certification for the self-taught ASP.Net programmer? [closed]

    - by Wahid Bitar
    I learned the C#.Net language from books and many other resources then i did some good projects with ASP.Net "Web Forms & MVC". But i wanna a good certificate to get a better work out of my country as i suppose. I've two choices: Apply for a " college / institute " and start study academic courses to be more professional and maybe in two years I'll "hopefully" graduate with this college certificate. Apply for kind of " Certifications by Companies " like MCTS from Microsoft or something like that and study their straightforward courses then maybe with three or four months I'll get this "Not official Certificate". Is the second type of certifications good for learning and work or the best is the hard way ?. Please give me advises with certifications names please. ======================= Update: This is not related to certain country or region. I'm asking about a good certification and courses for an ASP.Net and C# in general programmer.

  • Should HTTP Verbs Be Used Semantically?

    - by Xophmeister
    If I'm making a web application which integrates with a server-side backend, would it be considered best practice to use HTTP methods semantically? That is, for example, if I'm fetching data (e.g., to populate a menu, etc.), I would use GET, but to update data (e.g., save a record), I would use POST. (I realise there are other methods that may be even more appropriate, but we need to consider browser support.) I can see the benefits of this in the sense that it's effectively a RESTful API, but at a slightly increased development cost. In my previous projects, I've POST'd everything: Is it worth switching to a RESTful mindset simply for the sake of best practice?

  • How do I avoid the complexity concerns of frameworks while keeping my team marketable?

    - by Desolate Planet
    When deciding upon how to design a software project with my colleagues, most suggestions tend to be for using specific frameworks "because it's popular in the job market" or "that's the framework that gets recruiters on the phone," and never what I'm looking for which is, "because it's a good fit for the project as it makes the system more adaptive to future changes and makes life easier for developers." I didn't start looking at projects in this way until I started reading up on domain-driven design. I've found that the actual domain is hidden deep under the frameworks used and it's hard to learn the business processes that have been implemented by the software product. Is there a way to marry the two competing goals: getting exposure as a development team while still being able to avoid complexity? Are frameworks that compromise, or are there other solutions out there?

  • Is it ethical for a programmer to promote his/her own library?

    - by Kit Menke
    Fairly recently I started maintaining my own open source JavaScript library. I created it to solve a pretty specific need but fairly regularly see questions that can be solved (in whole/part) by using my library. I've always gone ahead to post my answer including my library and make sure to always include a disclosure specifying that I maintain it. I feel for open source projects this may not be such a big deal but where do you draw the line? (ex: commercial products) Is it ethical for a programmer to promote is own library? When is it not?

  • Starting Game Programming in C++, where to begin for optimal cross-platform development?

    - by Qasim
    I wish to begin learning game development in C++. I have knowledge in syntax and the console using Visual C++ 2010, however I want to begin programming. My only problem is that I want to be able to support many platforms including Windows, Mac OS, and Linux. As I get better, I also hope I can submit games to XBLIG (or XBLA) and Steam, and even the Google Play Store (But that would take some porting and major redesign of controls). I have looked into c++ and SDL but I have no idea how to get started. I have Visual C++ 2010 installed and I hope I can still use that as other C++ IDEs are quit outdated. Because I want to stick with Visual C++ and SDL (unless there is a better library than SDL), there is not much room for debate but rather how to create projects to support cross-platform development.

  • How do I dig myself out of this DEEP hole? [closed]

    - by user74847
    I may be a bit bias in the way i word this but any opinions and suggestions are welcome. I should start by saying i have a MSc in CS and a degree in new media +6 years expereince and im probably around a middleweight developer. I started a web development company with my friend from uni a year ago, there was a 4 month gap in the middle where i went miles away work on a big project. Ive since returned and picked up where we left off. A year on though i find im still staying up til 5am and getting up at 9 sometimes 2-3 days without sleep. While i was away i was working 9-5 and struggling to keep up with doing stuff for my clients 8 hours ahead, after work, so things stagnated. We currently have about 12 active projects, with one other part time developer and a full time freelancer who is dealing with one of our major projects. I am solely responsible for concurrently developing 2 big sites similar to gumtree in functionality, at the same time as about 5-6+ small WordPress based 5-10page sites. a lot of the content isnt in yet or the client is delaying so i chop and change project every other day which does my head in. Is it reasonable to expect myself to remember the intricate details of each project when i come back to it a week later? and remember the details of a task which hasnt been written down? my business partner seems to think so. or am i just forgetful? Im particularly bad at estimating timescales which doesnt help, added to that a lot of the technologies im am using are new to me (a magento site took weeks to theme rather than days and was full of bugs, even after 1000's of google searches and hours reading forums) im still trying to learn and find the best CMS for us to use and getting my head around the likes of Bootstrap and jquery, Cpanel / Linux (we just got a blank vps for me to set up with no experience) even installing an SSL certificate caused everyone's mail clients to go down which was more stress for me to sort out. I find the pressure of the workload and timescales and trying to learn this stuff so fast is beginning to turn me against my career path. The fact that i never seem to get anything done really winds up my business partner and iv come to associate him with the stress and pain of the whole situation especially when I get berated or a look that says "oh you retard" when I forget something. Even today i spent hours learning how a particular themeforest theme worked with wordpress and how i could twist it to work for our partiuclar needs, on the surface had done no work, that triggered a 30 minute tirade of anger and stress and questioning what i had done from my business partner. had i taken too long to work on that? shoudl i have done it in 2 hours instead of 6? i told him i would take 2 hours. i was wrong. I feel like im running myself into the ground. My sleeping pattern has got so bad that when im working im half asleep and making mistakes, my eyes are constantly purple underneath, i literally fall asleep at my desk, its affecting my social life too, ive not slept more than lightly for the last year and grind through impossible code puzzles in my half sleep wich keeps me awake, when im already exhausted. plus the work is rushed and buggy when it does get done so drags on into the next project. I also procrastinate quite badly, pacing the livingroom, looking out the window when Im alone for three days straight in the flat and start to get cabin fever which means i do even less work and the negative feedback loop continues. I get told im the only one with the problem when i say that i cant work from home any more, and examples of other freelancers get brought up. an office wouldnt bring any extra cash in to the company but im convinced having that moving more than 2 meters away from my bed to go to "work" would get me working, at the moment i feel guilty like i should be working 24-7. It is important that we do all this work to raise enough cash to get our business to the next level but every month still feels like a struggle to pay the rent (there is about £20K coming in by Jan) and i have to borrow money from friends often to buy food or get a taxi to a meeting, so it is vital the money keeps coming in. (im also 20 mins late for nearly all meetings but thats a different issue) have you experienced anything similar? how can i deal with the issues ive raised? is it realistic to develop 10 sites at once? how can i improve my relationship with my business partner? do you struggle to work at home? how do you deal with that? i think if i dont get my life on track by feb i will seriously consider giving it all up, but that seems like such a waste. any ideas!!? i need help! Thanks.

  • How do I add Different Screens to my C#/XNA Game?

    - by Ramses Brown
    I'm working on a Pong clone in XNA. Gameplay-wise, I have it where I want it to be. I want to add a title screen and some other screens to it like a menu, as well as a screen for the Winning/Losing results. I've tried the Game State Management Example on the App Hub site, but It's very complicated and I haven't been able to make sense of it. Is there a simpler way? I'm hoping for a solution that can be used in other projects too. Plus I'd like to know how to actually create menu items (basically, how do I display the different options on it, and highlight them, etc).

  • How to get experience in large scale databases?

    - by Justin
    I have written applications that are very small scale and the code I write works fine for them. But I have often wondered how the server side code I write would scale up from 100s of queries per day to millions. Also when looking at possible jobs/projects, people are often looking for developers with experience in this sort of high traffic database design so I would at least like to be able to say, I havent gotten to work on a project that was this popular, but I at least have tried to simulate it. Are there tools or frameworks that can generate a lot of traffic or at least simulate what would happen with traffic on different orders of magnitude so I could get some practice writing optimized code for higher traffic applicaitons?

  • What do you miss when you have to use C instead of C++?

    - by sharkin
    This is not a question about which of the two languages is better than the other. I myself can't really decide. Pros and cons as always I guess. Also, if you feel you always would prefer C over C++, this poll is not for you :-). However, when I work in C projects I usually feel I'm missing a few language constructs more than others, which can be found in C++. For example, I usually miss (the obvious) classes, but seldomly templates (I always miss STL, but wouldn't call it a language construct). What do you miss when you have to use C instead of C++?

    I'm trying to load a website I've development and transferred from windows to ubuntu. I've installed apache2/php5/mysql and I've confirmed that it works by using the default index.html file displaying something like "It Works!". I've also created arbitrary folder containing some php file that I've run in firefox and it was displayed. But when I try to run my projects index.php I get a blank screen. I've consulted mirc about this and they say that it has to do with file permission. I've chcked the file permission on my index.php file and it is owner : rw r , group : r, others : read-only and execute is unchecked. What am I doing wrong?

  • What is the best agile project management technique for developing innovative software systems?

    - by user654019
    I am involved with the development of innovative software. The development is innovative since we don't know how to develop it and what algorithm should we use to implement and nobody else did it before. The process consists of several stages of studying books/papers, suggesting algorithms, writing prototypes and comparing the result with actual data. We hope that after some iteration, we converge to a valid software system. What is the best project management approach that we can use? Is there any project management software for these types of projects?

  • Renaming hundreds of files at once for proper sorting

    - by Mew
    I have a ton of files, all named stuff like 1.jpg, 2.jpg, 3.jpg, and so on up to 1439.jpg. However, I have a problem with one of my projects and alphabetizing. It will usually go in the order 1.jpg, 10.jpg, 11.jpg and so on. What I need is some way (or a script) to name the files so they are in the format such as 00001.jpg all the way up to 01439.jpg. How would I be able to do this quickly and efficiently?

  • Why is git-svn useful?

    - by Wes
    I have read these related questions: I'm a Subversion geek, why should I consider or not consider Mercurial or Git or any other DVCS? git for personal (one-man) projects. Overkill? ...and I understand why git is useful. What I don't understand is why tools like git-svn that allow git to integrate with svn are useful. When, for example, a team is working with svn, or any other centralised SCM, why would a member of the team opt to use git-svn? Are there any practical advantages for a developer that has to synchronize with a centralized repository?

  • Server costs and back loading for mobile devices

    - by user23844
    A company approached me to design an MMO for the mobile platform and I have the perfect idea for them. My question is how much would a server for a FTP game that has both a PVE element and PVP cost? Also do you think that it would be better or is it even possible to back load the data onto the phones (trying to come up with some interesting way to back up the data in case of emergency). I don't want the game to be totally online reliant (I want to appeal to not only phone users but also iPod touch users) and for there to be an offline mode. If you can't tell this is my first game besides simple projects I've done on the side. Any help would be greatly appreciated.

  • Why does DirectX use a left-handed coordinate system?

    - by greyfade
    I considered posting on Stack Overflow, but the question strikes me as being far too subjective since I can't think of a reasonable technical explanation for Microsoft's choice in this matter. But this question has bugged me for so long and the issue keeps coming up in one of my projects, and I have never actually seen an attempt at explaining this: OpenGL uses a right-handed coordinate system, where the +Z part of the world coordinate system extends toward the viewer. DirectX uses a left-handed system where the +Z part of the world coordinate extends into the screen, away from the viewer. I never used the Glide API, so I don't know how it worked, but from what I can gather, it uses a left-handed system as well. Is there a technical reason for this? And if not, is there some conceptual advantage to a particular handedness of a coordinate system? Why would one choose one over the other?

  • Ready to Open source the software, but want to make some money out of it.

    - by byteofprash
    I'm an UG Student and an Entrepreneur. I have started a small company with which I'm trying to provide solutions, to various companies in my city, through my software. I put in 30-40 hours of coding and development. I've been a huge fan of Open Source projects and I've also built by software on python. But now when it comes to selling my software to my customers, I expect money. (Am I being a Hypocrite?) Is there any OSS license under which I can make money and also make my source open? Please suggest. Or any other way to make money with my softwares? (I guess I deserve some credit. If not the code, atleast the ideas? :D )

  • Are there any reasons to use Bazaar over Hg or Git?

    - by NeuronQ
    The world of DVCSs seems split between Git and Mercurial nowadays, but lots of projects and places (like my new employer) use Bazaar. And it's not a thing of inertia where people just use something because "that's how it's always been done", these guys are agile and sometimes seem to embrace change just for the fun of having more things to fix. Yet no one gave me any convincing arguments for using Bzr over Hg or Git. I can get seeing Git as "too complicated" but you can't use this king of judgement between Hg and Bzr. So then, what are the features of Bazaar that would justify its use over Mercurial (or Git) in any given situation?

  • Should I work for free while applying for a job?

    - by Jevgeni Bogatyrjov
    An employer usually asks a candidate to do a small project at home ("homework") as a part of applying for a job. Last time I applied for a job (as a web developer), there were aproximately 10 applicants who were all given different tasks. Despite the fact that there was only one vacancy, the company used the work of all of the candidates in one of its projects. Actually, it is quite reasonable for a company to create these "vacancies" just to make people work for free - I estimate, that aproximately 2 weeks of programmer's work was saved with all of the job applications that company had on one vacancy. Is this a common practice and how can you protect yourself from working for free in the future? Have you seen this during your career?

  • How is Pash licensed?

    - by Jay Bazuzi
    Pash is an open source reimplementation of Windows PowerShell. It was released in 2008, and has been idle since then. I would like to take up the mantle. It's not clear what the license is. There is no LICENSE file or license details in the code. The only reference to a license I can find is on this page: http://sourceforge.net/projects/pash/ where it says: "License: BSD License, GNU General Public License (GPL)" But I'm not sure if I can take that as authoritative. I have tried to contact the author but he has not responded. I would hate to proceed with this project and later discover that I am violating a license, and have the project crippled as a result.
