  • How successful is GPL in reaching its goals?

    - by StasM
    There are, broadly, two types of FOSS licenses when it relates to commercial usage of the code - let's say the GPL-type and the BSD-type. The first is, broadly, restrictive about commercial usage (by usage I also mean modification and redistribution, as well as creating derived works, etc.) of the code under the license, and the second is much more permissive. As I understand, the idea behind GPL-type licenses is to encourage people to abandon the proprietary software model and instead convert to the FOSS code, and the license is the instrument to entice them to do so - i.e. "you can use this nice software, but only if you agree to come to our camp and play by our rules". What I want to ask is - was this strategy successful so far? I.e. are there any major achievements in the form of some big project going from closed to open because of GPL or some software being developed in the open only because GPL made it so? How big is the impact of this strategy - compared, say, to the world where everybody would have BSD-type licenses or release all open-source code under public domain? Note that I am not asking if FOSS model is successful - this is beyond question. What I am asking is if the specific way of enticing people to convert from proprietary to FOSS used by GPL-type and not used by BSD-type licenses was successful. I also don't ask about the merits of GPL itself as the license - just about the fact of its effectiveness.

  • What are the licensing issues involved in the Oracle/Apache java dispute?

    - by Chris Knight
    I've just started following with interest the soap opera involving Oracle's acquisition of Java and the detriment of goodwill it seems to have generated in the open source community. Specifically, I'm now trying to get my head around the implications of Oracle's decision to refuse Apache an open source license for Harmony. My questions: 1) What is Harmony anyway? Their website states "Apache Harmony software is a modular Java runtime with class libraries and associated tools". How is this different than J2SE or J2EE? Or is Harmony akin to Andriod? 2) The crux of this issue is around the Java Technology Compatibility Kit (or TCK) which certifies that your implementation adheres to the JSR specifications. If I understand correctly, Oracle refuse to offer free or open source license access to the TCK, denying projects like Harmony from being released as open source. Why is this such a big deal for Apache? E.g. why can't (or don't) they release Harmony under a restricted license? 3) From this site is the following quote: It looks like Oracle’s plan is to restrict deployments of Java implementations in certain markets, particularly on mobile platforms, so that it can monetize its own Java offering in those markets without any competition. Presumably anything Oracle produced would be subject to the same restrictions it is imposing on others with respect to end-technology licensing, so how could they get a leg up on the competition? While no doubt distateful, wouldn't other competitors such as Google or Apache be able to release competing platforms under the same license as Oracle?

  • Dalvik + Java licensing question

    - by Andrew Bate
    This is a licensing question about the Dalvik and J2SE core libraries. In particular the license governing java.util.concurrent.SynchronousQueue. The license header of the class in the JDK source states that it is GPLv2 only (see grepcode). However, the same file in the Dalvik core libraries seems to be governed by the Apache 2 license only (see android source). How is this possible? I didn't think you could take GPLv2 source and re-license it as Apache 2. (It's obvious they did: a comment above the Java Doc even says "removed link to collections framework docs"!) I'm asking because I have a GPLv3 project and would like to include a derivative work of some source from the core libraries (either Dalvik or J2SE) but publish it under GPLv3. I thought I could do this with Apache 2, but not GPLv2. I know that the J2SE class source is itself derivative work from public domain source, but the changes from the original are substantial. (The original is available at gee.cs.oswego.edu if you are interested.) Therefore the android source really is just a copy of the J2SE source, but published under Apache 2 instead of GPLv2. Is Google really allowed to do this?

  • How do I get a new license for gDEBugger after the 1 free year?

    - by Byte56
    I downloaded the gDEBugger from gremedy over a year ago, with their one year free license. The license has since expired and their site says that I'll be presented with the option for 1 year free license the first time I run it after install. This doesn't happen when re-installing, it just tells me the license has expired. How do I get a new license? I use this regularly for debugging shader problems and performance testing my game.

  • Choice of open source license for some components, closed source for others

    - by Peter Serwylo
    G'day, I am working on a set of multiplayer games, where different games play against each other (e.g. you play a Tetris clone, I play an Asteroids clone, but we are both competing against each other). All the games would be based on the same underlying framework written specifically for this project. I am struggling to comprehend how I would license this so that: The underlying framework is open source, so other people can create new games based on it. Some games built on the framework are open source Other games are closed source The goal is to have two bundles on something like the Android market: One free and open source package which has a collection of games Another "premium" (although I dislike that word) paid package which has a different collection of games. Usually I am fond of permissive licenses such as MIT/BSD, however I would prefer something more in the vein of the GPL for this. This is because for software such as the snes-9x SNES emulator, which is a great piece of software, there is a ton of poor quality versions being sold, whereas it would be preferable if there was just one authoritative version which was always kept up to date, and distributed for free. If the underlying framework was GPL'd, would I be able to build closed source games on top of it? Thanks for your input.

  • Publish a software with copyright and license

    - by King Chan
    I just read some artical about publishing software and I am personally developing some random metero application at the moment. The artical were suggesting the software should have a publisher website. But what I have to put down in the publisher website to keep my copyright? Is it simply really just "Designed/Developed @ 2012 By King Chan" at the bottom of the site and software and is enough? Or do I have to even write a long paragraph of license/agreement said the user who download/use the software cannot copy the icon/functionality etc? (The Apple and Samsung things get me worry about CopyRight now....)

  • Review of ComponentOne Silverlight Controls (Free License Giveaway).

    - by mbcrump
    ComponentOne has several great products that target Silverlight Developers. One of them is their Silverlight Controls and the other is the XAP Optimizer. I decided that I would check out the controls and Xap Optimizer and feature them on my blog. After talking with ComponentOne, they agreed to take part in my Monthly Silverlight giveaway. The details are listed below: ----------------------------------------------------------------------------------------------------------------------------------------------------------- Win a FREE developer’s license of ComponentOne Silverlight Controls + XAP Optimizer! (the winner also gets a license to Silverlight Spy) Random winner will be announced on March 1st, 2011! To be entered into the contest do the following things: Subscribe to my feed. Leave a comment below with a valid email account (I WILL NOT share this info with anyone.) Retweet the following : I just entered to win free #Silverlight controls from @mbcrump and @ComponentOne http://mcrump.me/fTSmB8 ! Don’t change the URL because this will allow me to track the users that Tweet this page. Don’t forget to visit ComponentOne because they made this possible. MichaelCrump.Net provides Silverlight Giveaways every month. You can also see the latest giveaway by bookmarking http://giveaways.michaelcrump.net . ---------------------------------------------------------------------------------------------------------------------------------------------------------- Before we get started with the Silverlight Controls, here is a couple of links to bookmark: The Live Demos of the Silverlight Controls is located here. The XAP Optimizer page is here. One thing that I liked about the help documentation is that you can grab a PDF that only contains documentation for that control. This allows you to get the information you need without going through several hundred pages. You can also download the full documentation from their site.  ComponentOne Silverlight Controls I recently built a hobby project and decided to use ComponentOne Silverlight Controls. The main reason for this is that the controls are heavily documented, they look great and getting help was just a tweet or forum click away. So, the first question that you may ask is, “What is included?” Here is the official list below. I wanted to show several of the controls that I think developers will use the most. 1) ComponentOne’s Image Control – Display animated GIF images on your Silverlight pages as you would in traditional Web apps. Add attractive visuals with minimal effort. 2) HTML Host - Render HTML and arbitrary URI content from within Silverlight. 3) Chart3D - Create 3D surface charts with options for contour levels, zones, a chart legend and more. 4) PDFViewer - View PDF files in Silverlight! That is just a fraction of the controls available. If you want to check out several of them in a “real” application then check out my Silverlight page at http://michaelcrump.info. This brings me to the second part of the giveaway. XAP Optimizer – Is designed to reduce the size of your XAP File. It also includes built-in obfuscation and signing. With my personal project, I decided to use the XAP Optimizer by ComponentOne. It was so easy to use. You basically give it your .XAP file and it provides an output file. If you prefer to prune unused references manually then you can prune your XAP file manually by selecting the option below. I went ahead and added Obfuscation just to try it out and it worked great. You may notice from the screenshot below that I only obfuscated assemblies that I built. The other dlls anyone can grab off the net so we have no reason to obfuscate them. You also have the option to automatically sign your .xap with the SN.exe tool. So how did it turn out? Well, I reduced my XAP size from 2.4 to 1.8 with simply a click of a button. I added obfuscation with a click of a button: Screenshot of no obfuscation on my XAP File   Screenshot of obfuscation on my XAP File with XAP Optimizer.   So, with 2 button clicks, I reduce my XAP file and obfuscated my assembly. What else can you want? Well, they provide a nice HTML report that gives you an optimization summary. So what if you don’t want to launch this tool every time you deploy a Silverlight application? Well the official documentation provided a way to do it in your built event in Visual Studio. Click the Build Events tab on the left side of the Properties window. Enter the following command in the Post-build event command line: $Program Files\ComponentOne\XapOptimizer\XapOptimizer.exe /cmd /p:$(ProjectDir)$(ProjectName).xoproj In the end, this is a great product. I love code that I don’t have to write and utilities that just work. ComponentOne delivers with both the Silverlight Controls and the XAP Optimizer. Don’t forget to leave a comment below in order to win a set of the controls! Subscribe to my feed

  • Modern.IE VM license

    - by Thomas W.
    Microsoft provides some VMs for testing purposes (advertised on StackOverflow) and I'm trying to understand the license terms. The one I don't really understand is 1.b. You may use the software for testing purposes only. You may not use the software for commercial purposes. My thoughts: a) Testing a website in several browsers on several different virtual machines seems a quite professional approach. I hardly believe many private developers would do that. Of course they should, but which private developer has the time to do so? b) If that's really only available to private developers, what is the offer to companies doing the same thing? I am missing the advertisement for a paid service. My question as a non-native English speaker: Is testing by a company considered as a commercial purpose? Can I use the VMs within a company for testing or not?

  • Most appropriate OSS license for infrastructure code

    - by Richard Szalay
    I'm looking into potentially releasing some infrastructure code (related to automated builds and deployments) as OSS and I'm curious about how the various OSS licenses effect it. Specifically, LGPL prevents the code itself (part/whole) being modified into a commercial product (which is what I'm after), but allows it to be "linked to" in the creation of commercial products (also ok). How does the "linked to" clause relate to infrastructure code, which is not deployed with the product itself? Would the application still be required to provide "appropriate legal notices" (which I'm not fussed over)? Would I be better off looking at the Eclipse Public License?

  • LGPL License in commercial application

    - by Jacob
    I have searched around but I don't seem to be able to get a clear answer on my questions that I understand. I want to use the Xuggler library in my application, which is licensed either GPL or LGPL depending on whether I compile it myself. I don't intend to edit the library If I compile it myself and thus get a LGPL version of the library, can I use it in a commercial application without having to distribute the source code of my application? Furthermore, do I have to give my application the LGPL license as well? What other problems might using this library give me?

  • MIT and copyright

    - by Petah
    I am contributing to a library that is licensed under the MIT license. In the license and in each class file it has a comment at the top saying: Copyright (c) 2011 Joe Bloggs <[email protected]> I assume that he owns the copyright to the file, and can change the license of that file as he sees fit. If I contribute to the library with a new class entirely write by me, can I claim copyright of that file. And put: Copyright (c) 2011 Petah Piper <[email protected]> at the top?

  • How well do free-to-open-source-projects policies work in practice?

    - by Steve314
    In comparison with an open source license and requesting donations, is a free-for-open-source-projects (or free for non-commercial developers) closed source and otherwise commercial project likely to get more license fees? Or just to alienate potential users? Assume the project has value to programmers - I'm looking for generalizations here, though specific examples comparing existing projects will be very interesting. What I have in mind involves code generating programming utilities. And one issue I can think of, either way, is a near total inability to enforce any license restrictions. After all, I can't go around the internet demanding that everyone show me their source code just in case!

  • Anti Cloud Open Source License

    - by Steve
    I'm working on a browser based open source monitoring project that I want to be free to the community. What I'm worried about is someone taking the project, renaming it, deploying it in the cloud and start charging people who don't even know my project exists. I know I maybe shouldn't mind, but it just sticks in my throat a bit if someone took a free ride like that and contributed nothing back. Is there any common open source license that can prevent this. I know GPL or AGPL don't.

  • GPL/LGPL/MPL non-code content license

    - by user1103142
    I want to use a dictionary (basically a text file, and no code) that is included with an open office spell checking plug-in. The plug-in is under the tri-license GPL/LGPL/MPL which I don't understand. is that legal? If it is illegal, what if I wrote a script that uses the said open office plug-in to generate the dictionary (assuming it's technically possible, the script will generate all possible letter permutations, passes it to the plug-in and saves the correct ones) ? I will be using the dictionary in a closed source commercial application. The dictionary is in a language that has very little resources online, and short of making my own dictionary, there aren't any alternatives. Clarification: The script idea I mentioned above, isn't a weird technique, I would generate a document with all possible words and use open office with the plug-in installed to show spelling mistakes and remove them, isn't this the intended use of the plug-in (spell checking)?

  • License for library developed with commercial program

    - by Overv
    I'm developing a commercial application that largely depends on the functionality of a library that will be developed with it. I'd like to open-source this library, because it offers functionality that is not found elsewhere and can be useful in other applications. However, I will also use it in my own commercial application. I don't want to publish the source of the main application, but it is definitely not a derived work (think of calculator app using GPL licensed library to calculate sine). And if someone else commercially uses the library, I want to require them to publish any changes made. Is the GPL license suitable for this or is LGPL perhaps what I need?

  • Does NASA license the software that it develops?

    - by Abe
    NASA provides a visualization software called Panoply. There is a Credits and Acknowledgments page that acknowledges and lists the licenses of software dependencies, but provides no information about its own license. I have looked at other software produced by NASA, including the source code for GISS and can not find any information about a licence. The closest information that I can find is in the FAQ for the global climate model EdGCM Global that says the code is in the "public domain" is it standard practice at NASA to release code into the public domain? are there exceptions? Can I assume that Panoply is public domain and can be used without restriction other than than those imposed by licenses of software dependencies? Is the absence of specific permission to reuse the code a concern (this issue was raised in the answer to a separate question) How common is this practice across government agencies?

  • How To Purchase An MSDN License In India [closed]

    - by Subhash
    I need to purchase a single license for Visual Studio Professional with MSDN. The MSDN buy site (http://msdn.microsoft.com/en-us/subscriptions/bb841434.aspx) does not allow purchases from India. It directs Indians to purchase from resellers. I contacted Microsoft and they sent me a link to a list of resellers http://www.microsoft.com/india/originalsoftware/business/retailStore1.aspx Many of these resellers do not even have a website. Many of them do not exist at the addresses mentioned (they have moved). Microsoft support personnel also seem very cagey about releasing any information. They do not even read the mail. They simply resend their canned response with the same link. There are many resellers (not mentioned in the microsoft page) who are selling MSDN subscriptions. Are they legitimate? Here is one site: http://www.aditicomputers.com/developers-software/microsoft-visual-studio-2010-professional-with-msdn.aspx How do Indian developers purchase MSDN?

  • Unattended Install of Zend Server license

    - by Zoop - Josh
    I have a Zend Server 5.6 development license and I wanted to know if there is a way to apply the license during install, rather than via the web interface after it has installed. I ask because I administer our server environment via Rightscale and have automated the creation of the server, however it still requires manual input for the license details. We regularly fire up a staging server to do final tests before pushing to production and it would be great if it were completely hands off.

  • Is there an OSS license that works for this:

    - by mattcodes
    Say you started as SaaS service with freemium business model such 37Signals - Basecamp or Dropbox etc.. Is there an OSS license that says that you can use the source code etc.. but you cant release a SaaS based on it, esssentially released in good faith with non-compete expectations. e.g. if 37Signals released the source for highrise, basecamp etc.. someone could start 37signals4lesss.com (albeit once they built the same bit of provisioning logic) and damage the core business model.

  • BSD Sockets don't behave in a iPhone 3G environment

    - by Kyle
    I noticed that many times while developing for an iPhone 3G, BSD socket functions will simply fail. I also noticed at the time, the 3G antenna wasn't even ON, nor was there WIFI Access to back up the network call (So it seems ridiculous that it doesn't turn on to support the network request).. This information was verified with an app from Apple in the SDK called Connectivity Test, or something of the sort. Basically if you load Safari or something, then quickly load up the App it would be fine.. Of course that's not ideal. Apparently, to apple, gethostbyname() or something of the sort is by no means a reason to turn on the Antenna. I contacted Apple about this, and they said that the BSD functions do not switch the Antenna on, but calling all of the Objective-C CFNetwork functions do. I want portable code, so is there a way to keep my existing BSD setup? I really dislike coding in Objective-C, so if anyone knows a work around, that would be awesome.

  • How to efficiently protect part of an application with a license

    - by Patrick
    I am working on an application that has many functional parts. When a customer buys the application, he buys the standard functionality, but he can also buy some additional elements of the application for an additional price. All of the elements are part of the same application executable. A license key is used to indicate which of the elements should be accessible in the application. Some of the elements can be easily disabled if the user didn't pay for it. These are typically the modules that you can access via the application's menu. However, some elements give more problems: What if a part of the data model is related to an optional part? Do I build up these data structures in my application so the rest of my application can just assume they're always there? Or do I don't build them, and add checks in the rest of may application? What if some optional part is still useful to perform some internal tasks, but I don't want to expose it to the user externally? What if the marketing responsible wants to make a standard part now an optional part? In all of my application I assume that that part is present, but if it becomes optional, I should add checks on it everywhere in the application. I have some ideas on how to solve some of the problems (e.g. interfaces with dual implementations: one working implementation, and one that is activated if the optional part is not activated). Do you know of any patterns that can be used to solve this kind of problem? Or do you have any suggestions on how to handle this licensing problem? Thanks.

  • Open source real life license examples: yours or others

    - by donpal
    I'm aware of the usual list of open source licenses, so I'm not even going to list it here. What I'd like to ask is about your open source projects (whether out or planned for the future), and why you're planning to choose a certain license over the other. Basically say I went for X license because I wanted Y and that other license didn't provide it for me. I understand that the language itself can make a difference in the choice of license: interpreted languages like PHP vs. compiled languages like Java. I'm mostly interested in hearing about PHP projects, but of course additional insights are welcome. You may even have chosen that particular language for a licensing reason. Ideally I want to hear answers from people who were involved in the actual project (i.e. your own project), because that usually means you've put some thought into the license yourself and understand the implications of that license. But examples of existing projects that aren't your own are OK. Please just say why you think that license was good/bad for them. But first-hand experience is preferred. Looking forward to hearing some informative input.

  • Making money from a custom built interpreter?

    - by annoying_squid
    I have been making considerable progress lately on building an interpreter. I am building it from NASM assembly code (for the core engine) and C (cl.exe the Microsoft compiler for the parser). I really don't have a lot of time but I have a lot of good ideas on how to build this so it appeals to a certain niche market. I'd love to finish this but I need to face reality here ... unless I can make some good monetary return on my investment, there is not a lot of time for me to invest. So I ask the following questions to anyone out there, especially those who have experience in monetizing their programs: 1) How easy is it for a programmer to make good money from one design? (I know this is vague but it will be interesting to hear from those who have experience or know of others' experiences). 2) What are the biggest obstacles to making money from a programming design? 3) For the parser, I am using the Microsoft compiler (no IDE) I got from visual express, so will this be an issue? Will I have to pay royalties or a license fee? 4) As far as I know NASM is a 2-clause BSD licensed application. So this should allow me to use NASM for commericial development unless I am missing something? It's good to know these things before launching into the meat and potatoes of the project.
