  • Is there an Open Source licence matrix?

    - by tobsen
    I am trying to find a simple matrix overview of the various licenses around open source software but can't find anything useful. I would like to know whether software under a certain licence can be used in commercial closed source software, if there has to be the original source code included, if the licence has to be redistirbuted, etc. I know this is a difficult topic because I guess only the minority of programmers are also moonlighting lawyers - neither am I.

  • 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.

  • Start diving into large open source projetcs

    - by Vanangamudi
    How to start learning and reading the source of large and complex projects like Blender3D and Gimp, for instance. Since the developers busy improving it and there is no docs exist at present, how do we start developing and customizing these projects. Linux kernel deserve to have several books on its code, also these kind of project do deserve the same. And there are no unit tests available for this kind of projects. Say I'm going to read and understand the source code blender. How do I start. How to setup the development environment for developing the app? If it includes several dependencies, and assume that their source code also available how to setup this kind of inter-related, coherent source code to debug?

  • keyboard gets locked when editing source controlled files using Visual Studio 2008

    - by Rama
    Hi, I am facing a strange issue with editing source controlled files (especially aspx files) using visual studio 2008. when I check out and edit the file, I can edit fine for few seconds and after that keyboard gets locked and I can't type anything (it doesn't affect the files not added to source control). as soon it is locked, if I try to type, the focus shifts to solution explorer and other windows and sometimes it freezes and doesn't respond at all. I tried uninstalling and reinstalling visual studio, reinstalling the source control plug-in. none of it worked. not sure if it is my machine or my profile. Please help if you have any clues. I can't see any other solution for this except rebuilding the machine Update: I use Perforce plug-in for source control Thanks, Rama

  • SQL SERVER – CTRL+SHIFT+] Shortcut to Select Code Between Two Parenthesis

    - by pinaldave
    Every weekend brings creative ideas and accidents brings best unknown secrets in front of us. Just a day while working with complex SQL Server code in SSMS I came across very interesting shortcut which I have never used before and instantly fell in love with it. It is totally possible that you are familiar with this but for me it was the first time and I was surprised that I did know know this short cut so far. Shortcut key is CTRL+SHIFT+]. This key can be very useful when dealing with multiple subqueries, CTE or query with multiple parentheses. When exercised this shortcut key it selects T-SQL code between two parentheses. Let us see the examples to understand the same. In each of the examples I have put the cursor at the position displayed and pressed CTRL+SHIFT+] and it has selected the code between two corresponding parentheses. Cursor position 1 Cursor position 2 Cursor position 3 If you are a developer and have to code with complex queries, you will totally appreciate that this feature can save so much of the time for development. I often remember my experience as a developer when I have lost a lot of hours to just balance parentheses. As I said yesterday I found this shortcut accidently. How many of you were aware of this feature? Is there any other useful feature you would like to share with us? Please leave a comment and if I have not covered it earlier, I will share it due credit on this blog.

  • SQLAuthority News – Mark the Date: October 16, 2013 – Introducing NuoDB Blackbirds: THE Distributed Database

    - by Pinal Dave
    I am very excited to announce first on this blog about the release of NuoDB Blackbirds (NuoDB Release 2.0). NuoDB is my favorite application to work with data now a days. They are increasingly gaining market share as well as brining out new features with their every new release. I was very excited when I learned that NuoDB is releasing their flagship release of 2.0 on October 16, 2013. Interesting enough I will be in USA while this release happens and I will be watching it live during my day time. Even though if I had to stay up the entire night to just watch this release, I would do it. Here is the details of the announcements: Introducing NuoDB Blackbirds: THE Distributed Database Date: October 16, 2013 Time: 1:00 PM EDT Location: Online Registration Link What is the best DBMS architecture to handle today’s and tomorrow’s evolving needs? The days of shared disk are over. The times are “a-changin” and IT infrastructure has to change with them. Join NuoDB live for the introduction of our latest major product release, NuoDB Blackbirds, and take a look at why the NuoDB distributed database architecture is the only answer for customers like Fathom Voice, a leading provider of Voice Over IP (VoIP). NuoDB CEO, Barry Morris, welcomes Cameron Weeks, CEO of Fathom Voice to discuss how his company is using DBMS to break away from the pack and become the hottest player in VoIP. The webcast will include demonstrations of a single, logical database running in multiple geographies and a live Q&A. If due to any reason, you cannot watch it live, do not worry at all, just register at this Registration Link, as after the event you will get the link to watch the event on-demand. You can watch the launch event at any time if you have registered for the launch.

  • Test Data in a Distributed System

    - by Davin Tryon
    A question that has been vexing me lately has been about how to effectively test (end-to-end) features in a distributed system. Particuarly, how to effectively manage (through time) test data for feature testing. The system in question is a typical SOA setup. The composition is done in JavaScript when call to several REST APIs. Each service is built as an independent block. Each service has some kind of persistent storage (SQL Server in most cases). The main issue at the moment is how to approach test data when testing end-to-end features. Functional end-to-end testing occurs through the UI, and it is therefore necessary for test data to be set up before the test run (this could be manual or automated testing). As is typical in a distributed system, identifiers from one service are used as a link in another service. So, some level of synchronization needs to be present in the data to effectively test. What is the best way to manage and set up this data after a successful deployment to a test environment? For example, is it better to manage this test data inside each service? Or package it together with the testing suite? Does that testing suite exist as a separate project? I'm interested in design guidance about how to store and manage this test data as the application features evolve.

  • Distributed Rendering in the UDK and Unity

    - by N0xus
    At the moment I'm looking at getting a game engine to run in a CAVE environment. So far, during my research I've seen a lot of people being able to get both Unity and the Unreal engine up and running in a CAVE (someone did get CryEngine to work in one, but there is little research data about it). As of yet, I have not cemented my final choice of engine for use in the next stage of my project. I've experience in both, so the learning curve will be gentle on both. And both of the engines offer stereoscopic rendering, either already inbuilt with ReadD (Unreal) or by doing it yourself (Unity). Both can also make use of other input devices as well, such as the kinect or other devices. So again, both engines are still on the table. For the last bit of my preliminary research, I was advised to see if either, or both engines could do distributed rendering. I was advised this, as the final game we make could go into a variety of differently sized CAVEs. The one I have access to is roughly 2.4m x 3m cubed, and have been duly informed that this one is a "baby" compared to others. So, finally onto my question: Can either the Unreal Engine, or Unity Engine make it possible for developers to allow distributed rendering? Either through in built devices, or by creating my own plugin / script?

  • Can I send a ctrl-C (SIGINT) to an application on Windows?

    - by Matthew Murdoch
    I have (in the past) written cross-platform (Windows/Unix) applications which, when started from the command line, handled a user-typed Ctrl-C combination in the same way (i.e. to terminate the application cleanly). Is it possible on Windows to send a Ctrl-C/SIGINT/equivalent to a process from another (unrelated) process to request that it terminate cleanly (giving it an opportunity to tidy up resources etc.)?

  • Which open source PHP project has the 'perfect' OOP design I can learn from?

    - by aditya menon
    I am a newbie to OOP, and I learn best by example. You could say this question is similar to Which Scala open source projects should I study to learn best coding practices - but in PHP. I have heard-tell that Symfony has the best 'architecture' (I will not pretend I know what that exactly means), as well as Doctrine ORM. Is it worth it to spend many months reading the source code of these projects, trying to deduce the patterns used and learning new tricks? I have seen equal number of web pages dissing and liking Zend's codebase (will provide links if deemed necessary). Do you know of any other project that would make any veteran OOP developer shed tears of joy? Please let me add that practicality and scope of use is not a concern at all here - I just want to do: Pick a project that has a codebase deemed awesome by devs way better and greater than me. Write code that achieves what the project does. Compare results and try to learn what I don't know. Basically, an academic interest codebase. Any recommendations please?

  • A Cautionary Tale About Multi-Source JNDI Configuration

    - by scott.s.nelson(at)oracle.com
    Here's a bit of fun with WebLogic JDBC configurations.  I ran into this issue after reading that p13nDataSource and cgDataSource-NonXA should not be configured as multi-source. There were some issues changing them to use the basic JDBC connection string and when rolling back to the bad configuration the server went "Boom".  Since one purpose behind this blog is to share lessons learned, I just had to post this. If you write your descriptors manually (as opposed to generating them using the WLS console) and put a comma-separated list of JNDI addresses like this: <jdbc-data-source-params> <jndi-name>weblogic.jdbc.jts.commercePool,contentDataSource, contentVersioningDataSource,portalFrameworkPool</jndi-name> <algorithm-type>Load-Balancing</algorithm-type> <data-source-list>portalDataSource-rac0,portalDataSource-rac1</data-source-list> <failover-request-if-busy>false</failover-request-if-busy> </jdbc-data-source-params> so long as the first address resolves, it will still work. Sort of.  If you call this connection to do an update, only one node of the RAC instance is updated. Other wonderful side-effects include the server refusing to start sometimes. The proper way to list the JNDI sources is one per node, like this: <jdbc-data-source-params> <jndi-name>weblogic.jdbc.jts.commercePool</jndi-name> <jndi-name>contentDataSource</jndi-name> <jndi-name>contentVersioningDataSource</jndi-name> <jndi-name>portalFrameworkPool</jndi-name> <algorithm-type>Load-Balancing</algorithm-type> <data-source-list>portalDataSource-rac0, portalDataSource-rac1, portalDataSource-rac2 </data-source-list> <failover-request-if-busy>false</failover-request-if-busy> </jdbc-data-source-params>(Props to Sandeep Seshan for locating the root cause)

  • Would it be possible to create an open source software library, entirely developed and moderated by an open community?

    - by Steven Jeuris
    Call it democratic software development, or open source on steroids if you will. I'm not just talking about the possibility of providing a patch which can be approved by the library owner. Think more along the lines of how Stack Exchange works. Anyone can post code, and through community moderation it is cleaned up and eventually valid code ends up in the final library. For complex libraries an elaborate system should probably be created, but for a simple library it is my belief this is already possible even within the Stack Exchange platform. Take a library of extension methods for .NET for example. Everybody goes their own way and implements their own subset of what they feel is important, open-source library or not. People want to share their code, but there is no suitable platform for it. extensionmethod.net is the result of answering this call for extension methods, but the framework hopelessly falls short; there is no order, or structure at all. You don't know whether an idea is any good until you try it, so I decided to create an Extension Methods proposal on Area51. I belief with proper moderation, it could be possible for the site to be more than a Q&A site, and that an actual library (or subsets of it) could be extracted from it. Has anything like this been attempted before? Are there platforms better suited for this?

  • OpenSource license with commerial-use exemptions for the owner

    - by dbkk
    I'm looking for an open source license which grants me additional privileges. Features: Anyone can freely modify, fork, use the code, as long as they make their source changes publicly available. They can use it in other open source projects, but not in closed-source projects. Only I and entities I specifically designate can use the code as part of a closed-source application. I am also exempt from the duty to publish the source code changes. I'm not trying to forbid the commercial use, just to allow myself more flexibility to use the code, while still contributing to open source. I don't want to burn myself by being legally forbidden from using the libraries I wrote in my commercial projects. Large companies use such dual licenses to maintain an open source project, while also selling the premium version. Which licenses of this type are available? What caveats or obstacles exist?

  • What is the basic loadout for an open source web developer?

    - by DeveloperDon
    Thus far, I have mainly been an embedded developer, but I am interested in having the flexibility to do mobile and web development as well. I think my tools should include the following, but probably a lot more. LAMP stack. Java IDEs like Eclipse and IntelliJ. JS frameworks like Dojo, Node.JS, AngularJS, (is it better to mix or commit to one?). Cloud solutions like EC2 and Azure (again, ok to mix or better to commit to one?). Google APIs. Continuous integration server. Source control tools with Git for new work, SVN, CVS, +others for imports. FTP server. Unit test runners. Bug trackers. OOAD modeling tools or plug-ins? Graphic design tools? Hosting services. XML / JSON / other markup? Content management, SEO? I am also interested to know if there are tools where it might be better to mix, match, or support all available (maybe for source control) and others where the full focus should be on one (maybe Java vs. C# or Windows vs. Linux vs. MacOS). Perhaps some of these questions need context of whether the projects will be greenfield (just pick favorite) or maintenance (no choice, each project continues legacy, sometimes with a poor tools).

  • How to proceed when a bug in open source libraries is suspected?

    - by Suma
    We are using some open source libraries in our projects. Sometimes there are some issues found in some of them (most likely library bugs, but it may also be a wrong usage from our side, especially when sometimes documentation is not exactly 100 % complete). As the libraries are often quite complex, debugging them to pinpoint the source of the problem is sometimes quite hard. Can you help me to summarize what other options are there and how to exactly proceed with them? I have just recently hit some strange problems when using TCMalloc (Google scalable memory allocator) on Windows, so I would most welcome answers which would apply to this particular library, but more general answers are good as well. 1) Ask the maintainer/owner of the project for assistance. How can this be done? 2) Hire someone to identify and fix the issue. How to do this? How can I find someone with enough expertise in some particular library? ... any other options?

  • Open Source Project all dressed up but nowhere to go...

    - by Calanus
    Over the past 2 years myself and a colleague have built an online statistical analysis application using a mixture of silverlight, wcf and R. I (a c# programmer) wrote all the silverlight and wcf stuff whilst my colleague (a statistician) came up with the stats algorithms and wrote the R code. Now we think that this app is fairly unique - a rich gui online statistics application that is much more intuitive than all the other online stat apps that I've seen. But despite this we don't really know where to go with the project, mainly for the following reasons: 1) Its fairly complicated stuff - without the mix of programing and stats skills it would be difficult for anyone to "get into" the project and contribute. 2) We are stalled by a lack of a proper place to host the site. Currently it sits on the family windows 7 media centre, not exactly the best place to host it as it could interfere with the missus trying to watch Corrie/Friends/Oprah etc. Soo, anyone got any ideas on how to move forward with this? I guess that my strength is programing not marketing so despite working hard at this for the past couple of years I feel that I've reached a dead end! Also, does anyone know of any free windows hosting for open source projects? If I could find a proper place to put the app I might feel re-energised about the whole thing. The source code is on codeplex at: http://silverstats.codeplex.com, whilst the app is currently hosted at http://silverstats.co.uk

  • Is it worth moving from Microsoft tech to Linux, NodeJS & other open source frameworks to save money for a start-up?

    - by dormisher
    I am currently getting involved in a startup, I am the only developer involved at the moment, and the other guys are leaving all the tech decisions up to me at the moment. For my day job I work at a software house that uses Microsoft tech on a day to day basis, we utilise .NET, SqlServer, Windows Server etc. However, I realise that as a startup we need to keep costs down, and after having a brief look at the cost of hosting for Windows I was shocked to see some of the prices for a dedicated server. The cheapest I found was £100 a month. Also if the business needs to scale in the future and we end up needing multiple servers, we could end up shelling out £10's of £000's a year in SQL Server / Windows Server licenses etc. I then had a quick look at the price of Linux hosting for a dedicated server and saw the price was waaaaaay lower than windows hosting. One place was offering a machine with 2 cores for less than £20 a month. This got me thinking maybe the way to go is open source on Linux. As I write a lot of Javascript at work (I'm working on a single page backbone app at the moment), I thought maybe NodeJS and a web framework like Express would be cool to use. I then thought that instead of using SQL why not use an open source NoSQL database like MongoDB, which has great support on NodeJS? My only concern is that some of the work the application is going to do is going to be dynamically building images and various other image related stuff, i.e. stuff that is quite CPU heavy - so I'm thinking of maybe writing anything CPU heavy in C++ and consuming it as a module in Node. That's the background - but basically is Linux a good match for: Hosting a NodeJS/Express site? Compiling C++ node modules? Using a NoSQL DB like MongoDB? And is it a good idea to move to these unfamiliar technologies to save money?

  • Should I use my real name in my open source project?

    - by Jardo
    I developed a few freeware programs in the past which I had signed with my pseudonym Jardo. I'm now planning to release my first open source project and was thinking of using my full real name in the project files (as the "author"). I thought it would be good to use my name as my "trademark" so if someone (perhaps a future headhunter) googles my name, they'll find my projects. But on the other side, I feel a bit paranoid about disclosing my name (in the least case I could be getting a lot of spam to my email, its not that hard to guess your private email from your name). What do you think can be "dangerous" on disclosing your full name? What are the pros and cons? Do you use your real name or a pseudonym in your projects? I read this question: What are the advantages and disadvantages to using your real name online? but that doesn't apply to me bacause it's about using your real name online (internet discussions, profiles, etc.) where I personally see no reason to use my real name... And there is also this question: Copyrighting software, templates, etc. under real name or screen name? which deals with creating a business or a brand which also doesn't apply to me because I will never sell/give away my open source project and if someone else joins in, they can write their name as co-author without any problems...

  • Source of Unexplained Requests in Server Logs

    - by Synetech inc.
    Hi, I am baffled by some entries in my server logs, specifically the web-server logs. Other than normal, expected traffic, I have noticed three types of request errors (eg 404, etc.): Broken links, ie links from old, external pages that point to pages that are no longer here Sequences of probes, ie some jerk trying to hack in by scanning my server for a series of exploitable admin type pages and such What appear to be completely random requests for things that have never existed on the server or even have anything to do with the server, and appear by themselves (ie not a series of requests like the probes) Could it somehow be a mistyped URL or IP? That’s about the only thing that I can think of, but still, how could I get a request on say, foobar.dyndns.org (12.34.56.78) for something like www.wantsfly.com/prx2.php or /MNG/LIVE or http://ant.dsabuse.com/abc.php?auth=45V456b09m&strPassword=X%5BMTR__CBZ%40VA&nLoginId=43. (Those are a few actual requests from my logs.) Can someone please explain scenario three to me? Thanks.
