• Learning to use open source software [closed]

  - by dole

  Do you know any book, blog, tutorial which explains in a detailed way the use of some open source projects? Maybe you have written such a tutorial, example of open source libraries, and your final product is great for a beginner to understand it. I'm in the learning stage of OOP and I really need to learn by examples. I'll like to find some text which explains the use of some open source software/libraries and the good practices. Beign honestly I feel scared to use the open source libraries as I wish/think at this moment. I feel like as I still write procedural code and not OOP. Do you know such tutorials, links, blogs, stories, pages? PS: I know C and PHP. I can't say that I know C++ yet, and that's why I need your help.

• Looking for Open-Source or Licensed Personalised Greeting Card software

  - by Mr Pablo

  Before I jump in at the very deep end and try to make my own version of Moon Pig (www.moonpig.com) I would like to know what (if any) software/platforms currently exist that allow for visitors to personalise cards with text and uploaded photos and then purchase printed versions all via a single e-Commerce style platform. I have Googled till my fingers bled and I cannot find anything that matches my needs, which are: admin can provide templates (backgrounds) for the cards users can customise the card with text (font style and colour) users can upload their own photos (minor editing e.g. crop) to insert into the cards user can purchase a printed card via credit card payment Seeing as this kind of e-Commerce has been around for a while now, I would have thought there were some systems to purchase that can provide this functionality?

  - by Andreas

  I know this is may not be the right place to ask this sort of question,,on the other hand i am sure that it maybe the best...as many of you own a startup. I've been in the industry since 2006, mostly in consulting/business system analysis/project management jobs, not so much coding etc, and although i like working for the companies i am in at the moment...i daily think of starting up something on my own, consulting company,a software company with a good product, but it's the dilemma of making the first step, havent got much money saved up, i have a mortgage and about to start a family so as you can see it's difficult to let the security of a job and take the risk to just do it.... I am sure many of you have been in this dilemma, how did you start off? advice is greatly appreciated Andy

• Windows Server 2008 Antivirus Software with an API

  - by Dave Jellison

  I'm looking for an Antivirus package that is compliant with Windows Server 2008. That's not the hard part. What I need is an API layer on the Antivirus that i can call from managed .net code. For example: I am developing an Asp.Net (C#) website that allows users to upload files to the web server which the web site resides on. We have full control of the server so there are no security/rights issues on the server. I need to be able to run the antivirus algorithm on the newly uploaded files without (hopefully) shelling out to a command-ilne version of the software. Does anyone know of such a package?

• Making commercial Java software

  - by roddik

  Hi. I intend to make some software to be sold over internet. I've only created open-source before, so I have really no idea of how to protect it from being cracked and distributed as warez. Bearing in mind that I know like two programms that aren't either cracked or not really useful I decided that the only more or less reliable way may look like this: Connect to a server and provide licensing info and some sort of hardware summary info If everything is fine, the server returns some crucial missing parts of the program bound to that certain pc along with the usage limit of say 2 days That crucial stuff is not saved to hard drive, so it is downloaded every time the program starts, if the programm runs more than 2 days, data is downloaded again If the same info is used from different computers, suspend the customer account What do you think about this? It may seem a bit to restrictive, but I'd better make less sales at first then eventually see my precious killer app downloaded for free. Anyways, first I need some basic theory/tutorials/guides about how to ensure that user only uses a certain Java app if he has paid for it, so please suggest some. Thanks

• I'm trying to find an online classifieds software

  - by stackingtheoverflow

  ...for a client. Free or not, doesn't matter if its worth it. He told me he wants to do a Craigslist clone serving one specific geographical area only (a city that shall remain unnamed). It should also be multilingual and open-source (I want to be able to modify the code as needed). Right now I'm looking at ikiclassifieds.com, open-classifieds.com, and noahsclassifieds.org. Does anyone know of a classifieds software that meets the above mentioned criteria? Thanks!

• Project management software

  - by fahadsadah

  Hello I am looking for a decent web application that performs project management, and am hoping you guys can help me out. Requirements: Free, open source software. Runs from a Linux server (no ASP.NET). Git integration. GitHub integration is a plus. Tracks bugs and feature requests. Version tracking/scheduling, ie being able to say that a feature will be implemented for version X. I was looking at Redmine, but I don't know about the last item. Is there a plugin for that, perhaps?

• Software buttons in the android 4.2 emulator not showing up (tablet)

  - by The_Unknown

  I'm getting crazy right now. I just installed the latest android adt bundle from http://developer.android.com/sdk/index.html. It's version v21.0.0. Now I wanted to test my tablet app (designed for 10.1" xlarge mdpi) in the emulator, but I cannot get any software buttons for home/back/... Here's my device configuration. This config is afterwards assigned to the avd. http://i.stack.imgur.com/Q7xvP.png Hardware-buttons don't work as well (you cannot set hardware buttons in a tablet-like emulator). The target api is level 15 (android 4.0.3). I searched stackoverflow, but didn't find any help concerning the latest version of android. Since time's running away a little, any quick help would be great! Thanks in advance. Bye The_Unknown

• RAID Volume is no longer showing in Raid Controller BIOS and in Windows

  - by Gordon

  Hi all, I have installed some critical Windows Updates yesterday and now my external RAID Volume no longer shows in Windows Vista x64. All updates went through successfully. For their description, I cannot see how they should relate to the issue, but this is the only change that happened, so who knows. Anyway, here is the details: I have an external eSata enclosure that is running on a SiI4726 controller. I can connect to the controller with it's management utility from the computer the enclosure is connected to. The three drives in the enclosure show up as JBODs. I had those drives configured to be one logical RAID5 drive. RAID management is done through a SiI3132 SoftRaid controller. The Raid Management Utility just shows empty channels where it usually shows the Raid Group. In the Windows Disk Manager, I can see an unknown unitialized device. This is fine according to the setup manual. What it doesn't show is my Raid drive. It's gone. Also, when booting Windows, the BIOS of the controller used to show the RAID volume before booting the OS. This is not happening anymore. Updating drivers and firmware did not help. I have made sure the drivers and firmware are compatible to each others. And like I said, it used to work before. Any clues?

• What could be my path? Networking, programming, or something else?

  - by momong

  Well first and foremost, I would like to give my brief description: I was an aviation student but I didn't pursue that path because I lost my interest. Now I'm an I.T. student and currently stopped schooling because of confusion. I don't know which path I should choose: could it be programming or networking? Someone told me that on networking the money is easy, the job is easy. Others told me that programming is best suited for me because I'm very skilled and excellent at figures. I want to chose networking, but I can't find my passion for it, my mind tells me but my heart doesn't... and on programming, I don't know which language I should pick or if I like it or not. A good mentor, even if only online, would be a very big plus to me, but I don't think if there are many who could spent their time on teaching a nobody... but I'm very eager to learn. My real passion is gaming! I want to work in the gaming industry, I want to be a man behind those games! I've been a gamer freak since birth. But I don't know how to get in to that industry. I don't know what to do. I don't know which path would really suit me. Sorry if some of you find this a pointless question, but please bear with me, this could be the turn of my life.

• Why can't we capture the design of software more effectively?

  - by Ira Baxter

  As engineers, we all "design" artifacts (buildings, programs, circuits, molecules...). That's an activity (design-the-verb) that produces some kind of result (design-the-noun). I think we all agree that design-the-noun is a different entity than the artifact itself. A key activity in the software business (indeed, in any business where the resulting product artifact needs to be enhanced) is to understand the "design (the-noun)". Yet we seem, as a community, to be pretty much complete failures at recording it, as evidenced by the amount of effort people put into rediscovering facts about their code base. Ask somebody to show you the design of their code and see what you get. I think of a design for software as having: An explicit specification for what the software is supposed to do and how well it does it An explicit version of the code (this part is easy, everybody has it) An explanation for how each part of the code serves to achieve the specification A rationale as to why the code is the way it is (e.g., why a particualr choice rather than another) What is NOT a design is a particular perspective on the code. For example [not to pick specifically on] UML diagrams are not designs. Rather, they are properties you can derive from the code, or arguably, properties you wish you could derive from the code. But as a general rule, you can't derive the code from UML. Why is it that after 50+ years of building software, why don't we have regular ways to express this? My personal opinion is that we don't have good ways to express this. Even if we do, most of the community seems so focused on getting "code" that design-the-noun gets lost anyway. (IMHO, until design becomes the purpose of engineering, with the artifact extracted from the design, we're not going to get around this). What have you seen as means for recording designs (in the sense I have described it)? Explicit references to papers would be good. Why do you think specific and general means have not been succesful? How can we change this?

• How can I find the shortest path between two subgraphs of a larger graph?

  - by Pops

  I'm working with a weighted, undirected multigraph (loops not permitted; most node connections have multiplicity 1; a few node connections have multiplicity 2). I need to find the shortest path between two subgraphs of this graph that do not overlap with each other. There are no other restrictions on which nodes should be used as start/end points. Edges can be selectively removed from the graph at certain times (as explained in my previous question) so it's possible that for two given subgraphs, there might not be any way to connect them. I'm pretty sure I've heard of an algorithm for this before, but I can't remember what it's called, and my Google searches for strings like "shortest path between subgraphs" haven't helped. Can someone suggest a more efficient way to do this than comparing shortest paths between all nodes in one subgraph with all nodes in the other subgraph? Or at least tell me the name of the algorithm so I can look it up myself? For example, if I have the graph below, the nodes circled in red might be one subgraph and the nodes circled in blue might be another. The edges would all have positive integer weights, although they're not shown in the image. I'd want to find whatever path has the shortest total cost as long as it starts at a red node and ends at a blue node. I believe this means the specific node positions and edge weights cannot be ignored. (This is just an example graph I grabbed off Wikimedia and drew on, not my actual problem.)

• What is a widely accepted term for a string variable that would probably contain a file path and file name?

  - by Peter Turner

  For functions that need to index files in a directory and rename them FileName0001, FileName0002, etc... I often need to write a function that splits the file name from the file path and rename the file. When I put the file name and file path back together, I don't have a very good name for the variable that contains both of them and I usually just wind up concatenating them every time I want to use them (usually using them as parameters for functions labeled either filename or filepath) so I never really know what I'm doing until I notice a lot of files being written in the same directory as my binaries. Anyway, what do I call a file name and a file path? I don't want to call it File, because that usually means the binary information behind the file. I don't want to call it URI because that usually means I've got some sort of protocol, which I don't. I just want a good way to denote "c:\somedir\somedir\somedir\somefile.txt" so as to deconfuse this mess I've just realized I'm in. Please don't just list your personal preference. I think an excellent answer should "'site its sources". (as in, provide a link to a repository with a good example of the code being used as I described)

• What are some techniques to monitor multiple instances of a piece of software?

  - by Geo Ego

  It was recommended that I ask this question here by a member of StackOverflow. I have a piece of self-serve kiosk software that will be running at multiple sites. I'd like to monitor their status remotely. The kiosk application itself is pretty much finished. I am now in the process of creating a piece of software that will monitor all of the kiosks from a central location so that the customer can view particular details remotely (for instance, how many bills are in the acceptor's cash cartridge, what customer is currently logged in, etc.). Because I am in such an early stage of development, my options are quite open. I understand that I'm not giving very many qualifications, but I'd like to try to get a good variety of potential solutions. Some details: Kiosk software is a VB6 app running on Windows Embedded Monitoring software will be run on a modern desktop version of Windows (either XP, Vista, or 7) Database is SQL Server 2008 My initial idea was to develop a .NET app that would simply report the last database transaction for each kiosk at a set interval (say every second or so) but I'd really like for the kiosk software to report its status in real-time. I'm not exactly sure where to begin in terms of what modifications may need to be made to the kiosk software, and what the monitoring software will require. Links to articles on these topics would be most welcome.

• My father is a doctor. He is insisting on writing a database to store non-critical patient information, with no programming background

  - by Dominic Bou-Samra

  So, my father is currently in the process of "hacking" together a database using FileMaker Pro, a GUI based databasing tool for his small (4 doctor) practice. The database will be used to help ease the burden on reporting from medical machines, streamlining quite a clumsy process. He's got no programming background, and seems to be doing everything in his power to not learn things correctly. He's got duplicate data types, no database-enforced relationships (foreign/primary key constraints) and a dozen other issues. He's doing it all by hand via GUI tool using Youtube videos. My issue is, that whilst I want him to succeed 100%, I don't think it's appropriate for him to be handling these types of decisions. How do I convince him that without some sort of education in these topics, a hacked together solution is a bad idea? He's can be quite stubborn and I think he sees these types of jobs as "childs play" How should I approach this? Is it even that bad an idea - or am I correct in thinking he should hire a proper DBA/developer to handle this so that it doesn't become a maintenance nightmare? NB: I am a developer consultant of 4 years and I've seen my share of painful customer implementations.

• I am confused between PHP and ASP.NET to choose as a career in Indian software development context

  - by Confused_Guy

  I need your help(specially from the software professionals of India). I have completed MCA in 2009. After that instead of joining software company I did a Teaching job nearby by home. In the mean time I prepared myself for public sector jobs(bank). I continued my job for 1 year more and left it in 2010. Now in 2012 ,I feel that I should have done the software jobs,so that I could earn my bread and butter and in the mean time I could have prepared for the job.Because,according to my qualification it will give me the best salary. Now I want to go back in software industries. Now all of them are asking for experiences.And I don't have any.....So which language should I learn? And what should I do,because I have two year gap. Some of my friends suggested me to go with PHP as its easier and quicker to get job in India. But Here the PHP guys are getting less salary as compared to ASP.NET. I am planning to begin with PHP and but is it possible to switch to ASP.NET after two years experience. JAVA: I know upto servlet & JSP. Which is nothing in current market. ASP.NET: I know the basics of asp.net upto database connection ie(Gridview). PHP: Only the basics. So what should I do now. Which is most demanding. Does PHP is good, I feel its more like JSP pages. Please guide me, All your suggestions are needed for me.

• How can I get non-programmer colleagues on board with bespoke software rather than Dynamics CRM + Sharepoint?

  - by Bendos

  I am working with a company which designs and builds one-off machines. They have been 'dabbling' with hosted Dynamics CRM and Sharepoint (on different servers!) in an attempt to centralise their data and help colleagues collaborate more effectively across projects. They haven't used either system to their potential. Now we are looking at the engineering department who already use a form of version control software for the various CAD files (Autodesk Vault) however it is becoming increasingly necessary to implement more of a generic file version control system as they use many more files than can be managed in Vault (sometimes just photos or scans of paper documents), hence why they were looking at using Sharepoint. However... as the 'programmer' of the bunch, I can see several scenarios which don't seem to fit well with the Dynamics + Sharepoint approach; simple reports based on cross-table queries, exporting certain metrics as a spreadsheet, defining project hierarchies and many-many relationships, and as such I have been pushing for an in-house developed 'ECM' / 'ERP' software package (perhaps in .NET or php). Some colleagues seem to attach a greater value to the MS software (perhaps becuase it has a logo!) but don't see that it's just a framework, not a solution. Can anyone provide a good example of when custom software would actually be better than using Dynamics + Sharepoint and how do I relate that to non-technical staff?

• 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?

• Bug severity classification issues

  - by KyleMinn

  In a book I have, there is a following classification of defect: Critical : A defect receives a “critical” severity level if one or more critical system functionalities are impaired by a defect with is impaired and there is no workaround. High: A defect receives a “high” severity level if some fundamental system functionalities are impaired but a workaround exists. Medium: A defect receives a “medium” severity level if no critical functionality is impaired and a workaround exists for the defect. Low: A defect receives a “low” severity level if the problem involves a cosmetic feature of the system. To be honest, I do not get it.. For example point 2. What if fundamental but not critical feature is impaired and there is NOT a workaround. The same for point 3: what if no critical functionality is affected but there is no workaround? E.g. optional field in the registration form does not work. No workaround but barely an issue.
