  • Should I keep separate client codebases and databases for a software-as-a-service application?

    - by John
    My question is about the architecture of my application. I have a Rails application where companies can administrate all things related to their clients. Companies would buy a subscription and their users can access the application online. Hopefully I will get multiple companies subscribing to my application/service. What should I do with my code and database? Seperate app code base and database per company One app code base but seperate database per company One app code base and one database The decision involves security (e.g. a user from company X should not see any data from company Y) performance (let's suppose it becomes successful, it should have a good performance) and scalability (again, if successful, it should have a good performance but also easy for me to handle all the companies, code changes, etc). For the sake of maintainability, I tend to opt for the one code base, but for the database I really don't know. What do you think is the best option?

  • Which is better a computer science degree or a Software engineer degree?

    - by Shadow wolf
    I'm asking here so since you all have experience in or around game programming, that's what I want to do, and I’m trying to find as many options as I can before my senior year, which is next year. So do you have any opinions on the matter of which would give me a better education in programming? Please no talking about anything other than the two degrees because I know of game programming degrees out there but I like to see which of these would provide the best alternate choice.

  • How to cope with "Hidden IT..." Who writes and maintains the ad-hoc software applications?

    - by matcauthon
    Bigger companies usually have the problem, that it is not possible to write all programs employees want (to save time and to optimize processes) due to a lack of staff and money. Then hidden programs will be created by some people having (at least some) coding experience (or by cheap students/interns...). Under some circumstances these applications will raise in importance and spread from one user to a whole department. Then there is the critical point: Who will maintain the application, add new features, ...? And this app is critical. It IS needed. But the intern has left the company. No one knows how it works. You only have a bunch of sources and some sort of documentation. How do you cope with these applications? Can you "forbid" them? Can you control them? Do you have to write all apps (not Excel macros or some minor stuff) in the IT department?

  • Am I personally liable for bugs in medical software I've developed as an employee? [closed]

    - by user466406
    Some background: I'm employed at a small, Australia-based web agency that is dipping it's toe into Mobile Application development (iOS). The project that I'm working on provides a way for users to save medication dosage information which is sync'd with a backend server. Users must agree to ToS, Disclaimer etc before using the application. This is my first iOS application, and the project is currently over budget. As a result, management is not devoting the resources to Q&A and is pushing instead for more features. I am an employee of the agency, that has been contracted by a non-for-profit. The application will probably be released under our agency's name, but we also have the option of releasing it as the not-for-profit. My question is, if there are bugs found in the application, and as a result a user takes an incorrect dosage of a medication, am I personally liable? Is there anything that I can or should do in order to protect myself personally?

  • What are the pros and cons of public sector vs private sector software development? [closed]

    - by j.i.h.
    I'm currently considering a job working for my state of residence. However, besides the obvious drawback of far less compensation than I could get in the private sector, are there any other drawbacks? Are there any upsides to public work, besides helping society at large and benefits? My main concern is that if I work in the public sector, I might be stained with the perception that I "got along" in an uncompetitive environment. I have no idea if this would be the actual environment, but it seems to be the preconception about government work--unionized workers who are simply there because the union keeps them from being fired. So, does anyone have experience working for the government? Do you have experiences working with people transitioning from public to private sector?

  • What service or software should I use to serve advertising on a site with about 120k monthly page views?

    - by JasonBirch
    I have a site that is generating about 120k monthly page views and is being hosted on a shared FreeBSD server where I have access to PHP and MySQL. I am using some custom PHP server-side scripts that give each of my ad networks (AdSense, Tribal Fusion, etc) an adjustable percentage of impressions in each of the ad positions on my pages. I am looking for a better way of managing and measuring the delivery of these ads, and would also like to be able to take direct placements and provide statistics to the clients. I am looking at options including OpenX self-hosted, OpenX community, and Google DoubleClick for Publishers Small Business (DFP), but am having difficulty determining which one will best meet my needs. They all seem to have pretty steep learning curves compared to my simple scripts. What I have taken away so far as the benefit of self-hosting is that I don't have to pay for the service if I exceed a maximum number of ad impressions, while both OpenX Community and DFP have free impression limits. Of course, if I was doing those kind of numbers I'd need to upgrade my hosting account, but I'm not sure even at that point whether it would be cheaper to serve the ads myself than pay for a premium service. Apart from this, I really need insights into what features differentiate these services, why I might want to choose one over another, and if there are any other competing products or service of the same quality that I should look into. Answers from webmasters who have used both (or all three) services and can talk to usability and ease of ad management would be highly appreciated.

  • What would be the market life of a JVM based software framework?

    - by Nav
    I saw how Struts 1 lasted from 2000 to 2013. I hear that people are moving from Struts 2 to Spring. But for a project that may need to be maintained for a decade or two, would it be advisable to opt for a framework or directly code with servlets and jquery? Can a system architecture really be designed keeping in mind a particular framework? What really is the market life of a framework? Do the creators of the framework create it with the assumption that it would become obsolete in a decade?

  • Sortie de Joomla! 3.0.0, responsive design, installation simplifiée et nouveau module de statistiques

    Voilà qui est fait, six mois après la sortie de Joomla! 2.5 : la version 3. Tout d'abord, un mot sur le release cycle : la version 2.5 est une LTS (long term support), pas la 3.0. Cette dernière permet de casser pas mal de choses et ne sera donc pas supportée à long terme : il faudra attendre la 3.5 pour cela (au rythme d'une version mineure tous les six mois). La 2.5 sera supportée jusqu'à la sortie de la 3.5, au moins : il est toujours sûr de l'utiliser, elle sera toujours supportée? mais ne verra pas d'évolution technique. Avec la sortie de cette version 3.0, par contre, c'est le support de la vieillissante 1.5 qui est arrêté. La migration de la 2.5 vers la 3.0 devrait se passer sans heurts, sauf en cas d'utilisation intensive d'extensions (quelques modifications...

  • One sentence descriptions of the various common software licenses?

    - by Rich
    Instead of having to read entire documentation and sift through all the legalese, can someone outline the more common licenses in language that is short and sweet and gets right to the point? Specifically, I'm using a 3rd party control that uses the Apache 2.0 license. My intention is to use this in a proprietary application that I am building for a corporation's use (not resold, but I'm being paid for my work). Does this mean I can or cannot use this control? Does it mean that I must maintain copyright/license information in my code? Does it mean that I must mention copyright/license information in a clearly visible location in the app? EDIT In response to an answer below with a link to an article by Jeff Atwood, the Apache license is described as follows: Apache License Open Permissive 9 Requires derivative works to provide notification of any licensed or proprietary code in a common location. Does this notification need to be in a "common location" in my source code or a common location visible within the app? What if this were a non GUI app (I'm assuming that could very well be my answer)? Thanks for the responses!!!

  • What videoconferencing platforms work best for distributed software development teams?

    - by user11347
    Today I had a religious experience: I participated in a videoconference using a high quality Polycom system. This made a huge difference in communication quality -- people that I had a terrible time understanding previously now sounded like Shakespeare. Seeing a high quality video image was enormously helpful. I asked operations how much the Polycom cost and they said that it cost $20K new and $4K off eBay. So this solution doesn't work for people who work from home or who work in offices but are in groups of 3 or fewer people. My budget for a videoconferencing system is a few hundred dollars per person. Skype is not nearly good enough. And I haven't seen a consumer webcam that is good enough either. Does such a solution exist? I'm looking to collaborate both with people who are close by (in the same city but not in the same room) and far away (on different continents).

  • How to design an interface, where things need to be called in a specific sequence?

    - by Vorac
    The task is to configure a piece of hardware within the device, according to some input specification. This should be achieved as follows: 1) Collect the configuration information. This can happen at different times and places. For example, module A and module B can both request (at different times) some resources from my module. Those 'resources' are actually what the configuration is. 2) After it is clear that no more requests are going to be realized, a startup command, giving a summary of the requested resources, needs to be sent to the hardware. 3) Only after that, can (and must) detailed configuration of said resources be done. 4) Also, only after 2), can (and must) routing of selected resources to the declared callers be done. A common cause for bugs, even for me, who wrote the thing, is mistaking this order. What naming conventions, designs or mechanisms can I employ to make the interface usable by someone who sees the code for the first time?

  • Where can I find some software development freelance/contract positions? [closed]

    - by m-y
    I currently have a full time job as a Microsoft.NET developer, but I'd like to supplement my income by doing some part-time freelance development work. Are there any websites (or other sources) out there that specialize in this? While the website (or other source) does not have to be geared specifically for part-time work or Microsoft.NET development, if it is than that would be just wonderful. The only thing I could find close to this was www.vworker.com which is not that great.

  • How to design this procedural application into object oriented format?

    - by DavidL
    I'm building an application that basically pulls json data from a bunch of websites, processes it in some way and then writes it to a file. It is very easy to write this in a procedural way. I was wondering how this could be done in an object oriented way. Currently, the application looks something like this: res = get_json(link); process(res); write(res); Even if writing this in an object oriented way is not the best idea, tell me how it could be done because I have trouble with it.

  • Should I design and then look for a CMS or vice versa? [closed]

    - by Livingston Storm
    I am currently designing an e-commerce site, and unfortunately my PHP is garbage at the moment so open source CMS's are out of the question. I am debating between Joomla and Big Commerce and as the title states I am unsure of whether to build first or try the CMS first to see what limitations I will face. I couldn't find any previous questions on this site, forgive me if this is a stupid/commonly asked question. Thanks for any feedback

  • How should I design my website to allow posterity to edit?

    - by SSumner
    I'm building a website for a student organization I am involved in at my college. Most of the site will be static - i.e. won't change from year-to-year, but certain pieces will. I am high-tech, but most of the others aren't, and I am graduating in the spring. So how should I go about building the website so as to allow those that take over in subsequent years to edit information? Examples: Events: I already plan on using a Google calendar for this Officers: There will be profiles/pictures for all the officers on the web page Connections: Partnerships with other organizations that we have currently, but may not in future, or may add more in future Should I use some form of CMS (Content Management System)? If so, how restrictive are they (e.g. Drupal) to what you can build and then how easy is it to edit. What other ways could I make a very nice-looking website but allow certain pieces to be edited later?

  • For nodejs what are best design practices for native modules which share dependencies?

    - by Mark Essel
    Hypothetical situation, I have 3 node modules all native, A, B, and C.  A is a utilities module which exposes several functions to javascript through the node interface, in addition it declares/defines a rich set of native structures and functions B is a module which is dependent on data structures and source in A, it exposes some functions to javascript, in addition it declares/defines native structures and functions C is a module which is dependent on data structures and source in A & B, it exploses some functions to javascript, in addition it declares/defines native structures and functions So far when setting up these modules I have a preinstall script to install other dependent includes, but in order to access all of another modules source what is the best way to link to it's share library object (*.node) ? Is there an alternative best practice for native modules (such as installing all source from other modules before building that single module)? Reply

  • Multiplayer in a game. How to design it object wise?

    - by Ninetou
    I was suggested on StackOverflow to ask this question here. I'm working on a simple game and I was thinking of adding multiplayer feature but I'm a bit stuck. I'm not sure what approach should I take, keeping in mind good programming practices. I have a Player object which is created for each player but then I have many other classes that would have to be able to access them. The thing is, if I initialise them in, let's say my main method, then I can't relate to different instances of player class from other classes. The only solution to my problem that comes to my mind is using some form of global objects but afaik using anything globally in apps is usually not a good practice. Any suggestions/ideas?
