  • C# development with Mono and MonoDevelop

    - by developerit
    In the past two years, I have been developing .NET from my MacBook by running Windows XP into VM Ware and more recently into Virtual Box from OS X. This way, I could install Visual Studio and be able to work seamlessly. But, this way of working has a major down side: it kills the battery of my laptop… I can easiely last for 3 hours if I stay in OS X, but can only last 45 min when XP is running. Recently, I gave MonoDevelop a try for developing Developer IT‘s tools and web site. While being way less complete then Visual Studio, it provides essentials tools when it comes to developping software. It works well with solutions and projects files created from Visual Studio, it has Intellisence (word completion), it can compile your code and can even target your .NET app to linux or unix. This tools can save me a lot of time and batteries! Although I could not only work with MonoDevelop, I find it way better than a simple text editor like Smultron. Thanks to Novell, we can now bring Microsoft technology to OS X.

  • What would a start-to-finish development procedure would look like?

    - by Tom Busby
    I have a problem that my developer friends share. We recently left university and find ourselves either end up working for a firm which already has good procedures (TDD, automated testing, proper agile development, etc) or working for a firm which doesn't. I want to learn some of these vital skills and get a grip on what a complete start-to-finish development procedure would look like. What differences would be between a smaller project, and a long term project with many team members.

  • Does software architect/designer require more skills and intellectual than software engineer (implementation)?

    - by Amumu
    So I heard the positions for designing software and writing spec for developers to implement are higher and getting paid more. I think many companies are using the Software Engineering title to depict the person to implement software, which means using tools and technologies to write the actual code. I know that in order to be a software architecture, one needs to be good at implementation in order to have an architectural overview of a system using a set of specific technologies. This is different than I thought of a Software Engineer. My thinking is similar to the standard of IEEE: A software engineer is an engineer who is capable of going from requirement analysis until the software is deployed, based on the SWEBOK (IEEE). Just look at the table of content. The IEEE even has the certificate for Software Engineering, since ABET (Accreditation Board for Engineering and Technology) seems to not have an official qualification test for Software Engineer (although IEEE is a member of ABET). The two certificates are CSDA and CSDP. I intend to take on these two examination in the future to be qualified as a software engineer, although I am already working as one (Junior position). On a side note on the issues of Software Engineer, you can read the dicussion here: Just a Programmer and Just a Software Engineer. The information of ABET does not accredit Software Engineer is in "Just a Software Engineer". On the other hand, why is Programmer/Softwar Engineer who writes code considered a low level position? Suppose if two people have equal skills after the same years of experience, one becomes a software architect and one keeps focus on implementation aspect of Software Engineering (of course he also has design skill to compose a system, since he's a software engineer as well, but maybe less than the specialized software architect), how comes work from Software Engineer is less complicated than the Software Architect? In order to write great code with turn design into reality, it requires far greater skill than just understanding a particular language and a framework. I don't think the ones who wrote and contributing Linux OS are lower level job and easier than conceptual design and writing spec. Can someone enlighten me?

  • The road from software support to software development

    - by brokenisfixed
    I am at a crossroad - I've been working for whole 4 years as a support person fixing countless bugs, developing (minimal) changes and improvements to our software, working together with our clients and users. I started as a complete noob, without a good understanding of .NET, C#, SQL Server, etc. I had to work late nights and weekends just to catch up to my co-workers and to prove to myself that I am capable to do the work and do it good. I don't consider myself an expert in those fields, but I feel pretty comfortable working with them ;) I think I have had enough of it and I want changes - I want to move away from support and start working as a developer ;) If there is anyone who has gone this road before? Could you, please, share an advice or two?

  • Business guy building a software company [closed]

    - by Dreamer
    I am a business guy who is about to embark on a very risky journey to start this own software company. I have done sales for several software companies and in the last 8 years, I have managed to generate over $15 million in pure SAAS revenues for my employers. I think now its time to do it for myself and see where I can take the business. I have an idea in mind which I would like to develop and have been speaking with several companies who I may hire to convert that idea into a SAAS based offering. I am scared of the following: Being ripped off as I have no technical knowledge Over-charged Building something and realizing the foundation was weak, not scalable etc. Can anyone help me identify what I need to do before I sign a software development company to start my project. What do I need to know? What is the typical cost? What is a realistic time frame? Which coding language is better? What steps can I take to prevent myself from being ripped-off?

  • Web Developer or Software Engineer?

    - by dahacker89
    A question that I have been asking myself and really confused which path to take. So I need your guys help as to the pros and cons of these 2 professions in today's world. I love web applications development as the Web is the best thing to happen in this age and nearly everyone gets by on the World Wide Web. And also tend to keep learning about new technologies and about web services. On the other hand I like software engineering also for the desktop applications as I have had experience with development small scale softwares in VB.Net, Java, C++, etc. Which path has more scope and better future? Whats your view?

  • Shared Development Space

    - by PatrickWalker
    Currently the company I work in gives each developer their own development virtual machine. On this machine (Windows 7) they install the entire stack of the product (minus database) this stack is normally spread amongst multiple machines of differing OS (although moving towards windows 2008 and 2008r2) So when a developer has a new project they are likely to be updating only a small piece of their stack and as such the rest of it can become out of date with the latest production code. The isolation from others means some issues won't be found until the code goes into shared test environments/production. I'm suggesting a move from functional testing on these isolated machines to plugging machines into a shared environment. The goal being to move towards a deployment thats closer to production in mechanism and server type. Developers would still make code changes on their Win7 vm and run unit/component testing locally but for functionally testing they would leverage a shared enviornment. Does anyone else use a shared development environment like this? Are there many reasons against this sort of sandbox environment? The biggest drawback is a move away from only checking in code when you've done local functional testing to checking in after static testing. I'm hoping an intelligent git branching strategy can take care of this for us.

  • My software is hosted on a "bad" website. Can I do anything about it?

    - by Abluescarab
    The software I've created is hosted on what you could call a "bad" website. It's hard to explain, so I'll just provide an example. I've made a free password generator. This, along with most of my other FREE software, is available on this website. This is their description of my software: Platform: 7/7 x64/Windows 2K/XP/2003/Vista Size: 61.6 Mb License: Trial File Type: .7z Last Updated: June 4th, 2011, 15:38 UTC Avarage Download Speed: 6226 Kb/s Last Week Downloads: 476 Toatal Downloads: 24908 Not only is the size completely skewed, it is not trial software, it's free software. The thing is that it's not the description I'm worried about--it's the download links. The website is a scam website. They apparently link to "cracks" and "keygens", but not only is that in itself illegal, they actually link to fake download websites that give you viruses and charge your credit card. Just to list things that are wrong with this website: they claim all software is paid software then offer downloads for keygens and cracks; they fake all details about the program and any program reviews and ratings; they and the downloads site they link to are probably run by the same person, so they make money off of these lies. I'm only a teenager with no means to pursue legal action. This means that, unfortunately, I can't do anything that will actually get results. I'd like my software to only be downloaded off my personal website. I have links to four legitimate locations to download my software and that's it. Essentially, is there anything I can do about this? As I said above, I can't pursue legal action, but is there some way I can discourage traffic to that website by blacklisting it or something? Can I make a claim on MY website to only download my software from the links I provide? Or should I just pay no mind? Because, honestly, it's a bit of a ways back in Google results. Thank you ahead of time.

  • Secure an Application/Software by expiration with Date?

    - by JNL
    I have been working on some software application and I update them every 6 months. Currently, the way I track the date is by extracting the date from the system when the user installes the application, encrypt it and store it in a file locally. Whenever the application is started, it checks if 6 months have passed, then it works or it doesn't, in which case it shows an error message telling the user to update. I wonder whether there is a better way to do this. Any comments or suggestions would be highly appreciated

  • Does it matter to you that a software is "available source" but not "open source"

    - by ccpod
    You probably know the list of open source licenses officially approved by the OSI. Most notably I guess would be the GPL, MIT, [insert your favorite license here]. I recently ran into a project which although was open source (the creator made all source code available), was not officially open source under one of those official licenses. It released the source, but made no promise to release the source in the future. It allowed modification suggestions, but made no promises to accept patches and disallowed external distribution of externally-patched versions. It allowed the use of the software in commercial or paid projects, but disallowed the sale of the software itself. I suppose it could be called "available source" not open source as we like to think of it. I can see why the management team of a company wouldn't want to do business with this software. They can't fork it, they can't sell it, they can't create their own version of the software and distribute it or sell it. But would it matter to you as part of a software engineering team who's just using this software? I can still get my work done with it, I can use it in a project for which I'm paid (but I can't sell the software itself, which I'm not in the business of doing anyway), and I can make changes to the code to make it behave differently for my needs (but I can't make those modifications public), and if I do want those modifications officially made available to others, the approval is up to the project itself and they choose whether to incorporate them in an official release or not. So we know that a company that wants to base its business on this "available source" software can't do that, but as someone from the software engineering team, would those differences matter to you or do they seem less relevant? Curious what others think of this.

  • Terminology: Difference between software interface, software component, software unit, software modu

    - by JamieH
    I see these terms used quite a lot between various authors, but I can't seem to fix upon definitive definitions. From my POV a software interface is a "type" specifying the way in which a software component may be used by other softare components. But what exactly a software component is I'm not entirely sure (and it seems no-one else is either). Same goes for software unit, and software module, although I suspect that a software unit is a smaller, ahem, unit than a component, and a software module has something to do with packaging. I hope this is not deemed (and downvoted) as frivulous, as I have serious intent in the asking.

  • Web application development over C++ development..

    - by learnerforever
    Hi, I am CS undergrad and CS grad. In college I used to program in C/C++/java and have pretty much stuck to the same skill set in industry with 3 years experience. I like thinking,reading,applying logic etc, designing data structures, but I have little patience with debugging large C++ code. And having to deal with low level stuff like memory fault,memory corruption,compilation/linking issues. My confidence in programming is getting down due to this, but I like being in technical field. Does web application development like LAMP suit (Linux,apache,mysql,php),CSS,scripting (AMONG OTHER WEB DEVELOPMENT RELATED SKILLS) etc need lesser patience with debugging,and understanding of low level stuff, but your analysis/logical skills also get used? Also opportunities in web application development look more. Things like scalability, most of the stuff that Google does fascinates me, but for patience needed for dealing with C++ debugging. I make blunders while coding. How does the field look like outside C++? I am beginning to wonder if as a female, by moving to web application development, I can better manage work life balance. I have seen relatively lesser females in C++ than in Java/.net. Not very sure about web related stuff though. Also, what are the other hot technologies being used in web application development? lamp,css is something I know vaguely. Not in touch with keywords going on in this area. Please help!!.

  • Mobile Development- Obtaining development hardware - best practices?

    - by Zoot
    I'm looking to get into smartphone development, but there a quite a few options out there for platforms right now. (iOS/Android/WebOS/Bada/Symbian/MeeGo/WindowsMobile/JavaME) I'd like to have development hardware to test my code and the overall functionality of the devices. What is the best way to obtain and/or borrow hardware for development and testing? Are there rules of thumb to follow which apply to all companies and platforms? In this situation, I'm a single developer. Does this process change for a startup? A hackerspace? A small business? A large business? Thanks.

  • What is your opinion on free software? [closed]

    - by Joe D
    I use mostly free software on my main machine, and most programs that I write come out under either the GPL or BSD. I dislike proprietary software and prefer not to use it if a free software alternative is viable (read as: good enough). What are your opinions on free software? Do you use or develop for it? Why do you use it? Why don't you? Are you as extremist as RMS, and use only free software?

  • Software location after installing via Ubuntu Software Center

    - by Anh Tuan
    Let me tell you my problem: I just move from Windows 7 to Ubuntu and I'm trying to setup my programming environment. I installed Eclipse via Ubuntu Software Center, then opened it and installed additional plugins. Problem came up when I tried to install Subclipse: according to the official guide, I installed JavaHL, but that damned library wasn't automatically linked by Eclipse, so I was told to "Note that JavaHL does not install in a location that is on Eclipse's default path, so eclipse must be launched with -vmargs -Djava.library.path=/usr/lib/jni". Yes I know I have to modify eclipse.ini and add that vmargs line, but where is eclipse.ini??? I opened /usr/bin, the eclipse.exe is there but I can't found the rest. I really don't want to remove this Eclipse and download another from Eclipse download page, because I will have to reinstall every plugins again. Please can anyone tell me how to find the directory which contains software which installed via USC? Any help will be appreciated.

  • Why isn't software as reliable as a car?

    - by Alex Angas
    I had a user ask me this question. We know that cars break down, but that's because of something physical (unless software is involved!). I tried to answer that software is a much younger industry, but the user countered with "didn't the automobile industry become much more stable than and reliable with less people?". I also tried to answer that software is more complex, but the user countered that there are many thousands of parts that make up a car. People that design and build cars generally just know their component(s) very well, but they still all end up working together as an end result. So, why isn't software as reliable as a car?

  • who are software design engineers?

    - by Sepala
    My question is, who are software design engineers? And, what is the meaning of the following statement (from a software design engineer job ad)? "Application domain knowledge is essential and....." What is application domain? SDLC? My hope is to become a software engineer one day (OK, to be honest, more than that. I need to be a legend), that who do programming (They say this job has no programming). I am following final year of my Bsc(Hons) in computing and I have completed a foreign diploma, majoring software engineering - Java technologies. Will this job experience help me out to get a job in my desired position, which is mentioned above, after the degree? Wikipedia and google never gave a clear straight forward answer!! Please help!

  • Trade-offs of local vs remote development workflows for a web development team

    - by lamp_scaler
    We currently have SVN setup on a remote development server. Developers SSH into the server and develops on their sandbox environment on the server. Each one has a virtual host pointed to their sandbox so they can preview their changes via the web browser by connecting to developer-sandbox1.domain.com. This has worked well so far because the team is small and everyone uses computers with varying specs and OSs. I've heard some web shops are using a workflow that has the developers work off of a VM on their local machine and then finally push changes to the remote server that hosts SVN. The downside to this is that everyone will need to make sure their machine is powerful enough to run both the VM and all their development tools. This would also mean creating images that mirror the server environment (we use CentOS) and have them install it into their VMs. And this would mean creating new images every time there is an update to the server environment. What are some other trade-offs? Ultimately, why did you choose one workflow over the other?
