• Secure Open Source?

  - by opatachibueze

  I want to make a delicate application of mine (an antivirus actually) open source but I want to have a control on who really obtains the source or not. Preferably they should apply and I or administrators approve their applications. Is there any online platform for this? The main reason for the control/security is to possibly prevent malware makers to easily discover how to bypass the stealth checking methods it utilizes for malware detection. Edit: I am looking for advice - possibly to hear from someone who has done something similar. Thanks!

• Any legal issue in developing app similar to others?

  - by demotics2002

  There is a game I want to develop for mobile devices e.g. cellphone/tablet. I have been looking for this game and couldn't find it so I decide to just do it on my own. But I'm worried that there will be legal issues. I'm sorry but I do not know what is the process in doing this. I noticed for example the game Bejeweled Blitz. If I develop something similar, do I have to contact the developer and ask for permission if I develop a game with similar rules but use shapes rather than jewels? The original game exists only on Windows for free. If I develop the game, exactly similar rules but different display, am I allowed to sell it? Thanks...

• Prevent product key from being used on multiple virtual machines

  - by Nahum Litvin

  I have a software product. it will probably run on VMs that have no network connection at all. I want the user to pay for each VM the user runs. I thought to ask the user for some kind of hardware ID and provide him with serial that is unique for his machine. But user can just copy the VM image and than have two machines running? So I thought of having a security dongle. But how can I prevent user from running two VM's on the same machine both connected to the same dongle? This should be only basic defense so that actual hacking will be required to breach the license and not only spinning one more VM.

• Open Source HTML/JS game(s) with license that would allow embedding in my app?

  - by DustMason

  I'm working on an educational app for kids. At the end of the sign-up process, the kids must wait for a confirmation from their parents in order to gain access to the app. While they wait for this to happen, we want to let the kid play a simple game as a way to keep their interest up. Is there a marketplace or repository for games with such a license that we could either purchase (affordably) or use for free in our own app?

• How should I license code written for a startup without a contract?

  - by andijcr

  I wrote a fair amount of code for a startup, but I haven't signed a contract before doing so. The only document that I signed with them does not mention the fact that I have to pass the rights on the code to them, and after a consulting with a lawyer it seems that I own the full rights. Now I want to preemptively correct this situation by giving them some sort of exclusive license. Is there an existing license for closed-source, exclusive use that is used in these cases or I simply write somewhere "I grant exclusive license to use and modify this piece of code to FooBar-inc at the followings conditions: bla bla bla signed me, them"?

• On what name should I claim copyright in open source software?

  - by ONOZ

  When I want to use the Apache 2.0 licence in my project, I should include this in the comments of my source code: Copyright [yyyy] [name of copyright owner] Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.

See the License for the specific language governing permissions and limitations under the License. What name should I fill in for [name of copyright owner]? I am currently working alone on this project, but I'm going to release the source code so there might be other contributors in the near future.

• Is there a certain way that I have to include a library and it's license?

  - by leaf68

  I know this may be a dumb question, but I'm only 15 so I don't really know how the legal part of it works. When I choose a .dll to be included in my project, Visual Studio only includes the .dll file with my project (of course) so I just copy the license and stick it in a folder called licenses. But now, I'm going to be making a program for a contest so I need to make sure I have the licenses done right or I'll get disqualified. So is there any specific location I have to keep the licenses in my project, is there a way for Visual Studio to automatically copy the license the way it does with .dll files and is there anything else I have to watch out for legally? PS: If it matters the libraries I'm planning on using right now are WriteableBitmapEx and AvalonDock Thanks

• Any patent issue if I want to call my classes "signal/slot" as in Qt?

  - by user129506

  I need to code a signal-like mechanism and I was thinking of using the same "slot" and "signal" terms to indicate the signal and the function that needs to be called. Since this is a commercial application I'd like to know if there might be any issue with using these names, e.g. if Qt has some sort of patent on them (I searched around but couldn't find it). I believe this is a stupid question since patenting a class name would be moronic, to say the least.. but anyway... To add some detail: my code is ENTIRELY different and has NOTHING TO DO with Qt except the above. I don't use moc or any Qt class.

• Do I have to release the code of a MIT licensed software running a GPL library?

  - by Belohlavek

  Lets say I'm using Node-Webkit, an MIT licensed app runtime. Now, let's say I decide to include a Javascript library which is GPL licensed: while I do not modify the downloaded JS file, I do write my own code making use of the library's functions. I plan to sell the final obfuscated executable and I'm wondering: what's the final license of the complete software? Do I only have to release the GPL library or does the GPL license apply for all the code I wrote? What happens to Node-Webkit's MIT license?

• How to release bundled software with different licenses?

  - by mritz_p

  Recently, I was in a situation where I wanted to release a simple piece of JavaScript software under an open source license. However, I withdrew from it because the software contained several open source components that were released under different licenses. Under what license should the bundled software be released (given that various third party components are mixed into the software at code level)?

• Using a GPL licensed library in a commercial app

  - by user577616

  I develop an android application and in my app I use a libary (jar) that I download from the internet. This jar is open-source under the "GNU General Public License v2". I tried to read the text of the license but had difficulty understanding it. My question is: can I use this libary without changing nothing in the jar in a commercial application? I will be making profit from selling my app which uses this GPL-ed .jar file. If possible, I would like to avoid converting my application to open-source.

• Can I publish my game code under GPL? How? What about an engine?

  - by Bane

  I made a game, and I am currently making a game engine. I want them both to be completely free and open source. What license should I choose? I was reading a bit on GPL, but that seems to be more suited for system code and libraries, AFAIK, as it doesn't permit the use of code for proprietorial software - which, in turn, implies that the code can be used in the first place. I can see that, obviously, game engines can be considered libraries, and therefor be used, but what about game code? Is there an alternative to GPL?

• Legality of modifying and distributing the JRE

  - by herpylderp

  I see that Google App Engine apps run on a so-called secured sandbox JRE; that is, a JRE that Google modified and that makes changes to certain JRE types. This is how GAE prevents developers from writing apps that can do things like: Access the local file system via File Make remote JDBC calls Use JNDI Lots of other restrictions We have a similar need where we have an app that developers will be able to write plugins for. These plugins will need to utilize an API (a JAR) that we distribute with our app. We cannot afford for plugins to do certain things, particularly on the end user's file system, and need to modify the File class in a similar manner that GAE does. Long back-story short, this means we'll need to ship our app with a custom, modified JRE. My question: is this legal to do, or did Google likely pay Oracle some fee to modify/distribute their own JRE for app engine?

• The shortest licenses

  - by Darek Nedza

  What are the shortest licenses with aims for programmers/code. I have found only MIT that is page-long. What are other licenses that have approximately the same length or even shorter? Edit: Ok, length is not only criteria(I haven't expected one-line licenses, I have understaminate you people). I need easy to read and short licenses. It is meant for people who want to use my code not for lawyers who want to read long licenses. I am creating small codes to use by most people probably free of charge. I don't want useless information to be required, for example: what is X(for example: what is software, source code etc.) very specific information(for example: you can use it shop, opera, school... free of charge; but instead "use it everywhere but don't take money" Depending on type of code I would like to allow/disallow commercial usage.

• Sample code under MS-PL: must leave original comments?

  - by wtjones

  I have some files in my project that started from a sample in the all-in-one code sample browser: http://visualstudiogallery.msdn.microsoft.com/4934b087-e6cc-44dd-b992-a71f00a2a6df Some files contain boilerplate code that I modify heavily. They contain MS comments at the top that mention the license, copyright microsoft etc. Am I required to leave the entire comment block at the top of the source files that I modify or is it okay to just include the MS-PL license in a separate file for the whole project?

• How can I make sure my evening project code is mine?

  - by Sebastian

  I'm a physicist with a CS degree and just started my PhD at a tech company (wanted to do applied research). It deals with large scale finite element simulations. After reviewing their current approach, I think that a radically different method has to be applied (they are using a commercial tool which is very limited). I'd rather base my research on an open source finite element solver and write a program which makes use of it. I'd like to develop this idea in the evenings, because that's the time that best suits me for programming (during the day I prefer reading and maths) and use it at a late stage of my PhD. I'd like to have the option to release my program as open source on my website as a reference, for future personal or even commercial (e.g. consulting) use. How can I make sure that my company doesn't claim the code ownership? I don't really I thought that a version control system could help (check out only in the evening). This would document that I programmed not during regular office hours (documented elsewhere). But these data can be easily manufactured. Any other ideas? I want to stress that I'm not interested in selling software. Jurisdiction is EU, if that matters. Thank you.

• GPL exception that allows linking to free licenses only?

  - by fNek

  There is the GPL license and the linking exception which allows closed-source programs to use the program as a library. There is also the slightly more restrictive LGPL (more restrictive than GPL with exception since it requires that the user can change the library in the resulting project, etc.). And there is the Cygwin exception that allows linking to open source programs. I see clear advantages: Open-Source programs may use the library. People may use these programs for closed-source programs, but then they lose the permission to use the (GPL) library. However, there are two things I don't like about the Cygwin exception: - Its legal status is disputed - I keep hearing that it is basically worthless - It requires certification by the OSI, I would rather have certification by FSF Is there an exception to the GNU General Public License that meets my requirements?

• License compatibility question

  - by Ivaylo Slavov

  I have a question regarding software licenses. I plan to put a license to a framework that I have written. My intention is that the license should be open, in order to maintain a community. Also I want to control when a new version is released and which changes will be included. The license should allow the framework to be used with commercial products, therefore respecting their own license. I have done some quick research and I decided to double license my work under the Apache License 2.0 (ASL) and Eclipse Public License (EPL). My point is that the EPL will provide me the ability to control the release cycle as well as the contributions to the project and the Apache license will take care for any patents a 3rd party might want to use in a derived work. Also both are open licenses. My question is related to the GLP and LGPL licenses. If I have the above licenses to my framework, will it be possible and legal, for someone to create a derived work of my framework, that is also a derived work of, or links a library that is under the LGPL license? Thanks in advance. EDIT: To be clear I will explain how I expect things to work. The framework will define some common API for certain functionalities as well as a Wrapper class that will invoke an implementation of that API. The Wrapper will be part of the framework, but it will internally call the actual implementation. This implementation should be in a separate library, and such libraries I would like to be developed and maintained by community. Surely the community will have to access the framework but I want to limit changes to the framework by the community but I want to provide freedom for any API implementation (a derived work of the framework). The framework will enable flexible configuration mechanisms that will tell which implementation of an API will be used.

• Which license text to sell my application

  - by ZedTuX

  I would like to sell (for a low price) my new application without DRM (like does Machinarium) on the Ubuntu software center and on a website with Paypal. When I have registered my application the Ubuntu software center and I've selected the licence, I just found "Proprietary" but in my application I have to provide a licence text that something different than just "Proprietary", isn't it? Do you know where I can find this kind of licence text ?

• What constitutes "commercial purposes"?

  - by RoboShop

  I'm looking at this license. It says that I can use it for "non-commercial purposes". What does that mean? I see in Stack Exchange, under Network Profile there is that graph that tracks your points across your Stack Exchange accounts. It uses a control called HighCharts which have a paid and Creative Commons licensed version. So would Stack Overflow constitute a commercial site? We don't pay to use this site, but obviously the site makes money from ads, etc. Then again, there's a lot of sites that have ads who won't necessarily make a profit, it may only be subsiding their costs. But even then, you could argue that even if it is only subsiding their costs, a lot of IT companies run at a loss in order to build a big enough customer base. So where is the line here? Is it any website on the internet? Is it any website that has ads? Is it any website that turns over a profit?

• Application of LGPL license on a simple algorithm

  - by georgesl

  The "scope" of the GNU license is troubling me : I know it has been answered many times ( here, here, ... ) but shouldn't we take into consideration the complexity and originality of a code before using GPL license ? I explain : I'm working on a pet project using the DTW algorithm that I have written in C using the pseudo-code given on the wikipedia page . At one point I decided to change it for a C++ implementation ( just for hone my c++ skill ) . After doing so, I've looked for an existing implementation on the web, to compare the "cleanliness" of it, and I found this one : Vectored DTW implementation, which is part of limproved, a C++ library licensed under GPL v3 . Personnally, I don't mind the GNU license because it is a personnal project, which will never led to any kind of commercial purpose, but I wonder if this implementation can abide a company using it to open their code ( and other FOSS permissions ). Theoretically, I think it can ( I may be wrong :p ), but the algorithm in question is so simple (and old) that it should not.

• Legally, can I re reuse code for different customers?

  - by canice

  The company I work for develops custom factory automation applications for multiple customers. Even though each application is custom, they contain common code which is re-used across projects. One of the customers is now looking for the source code to their application, which has caused a major storm in the company. Management have decided that we can't give them the source to the shared components as they are used by other customers. I've been asked to modify the shared components 'enough' so as they aren't common. So my questions are: 1) Legally, should there be any problem with re-using common components for different customer? 2) If I really need to modify the common components, then how much is 'enough' ? (I know this sucks, but I either do this or hand in my notice). Oh yeah, and my company has no license in place with any of these customers.

• Is this a typo in the Artistic License 2.0?

  - by IQAndreas

  I'm not sure if this would fit better in StackExchange/English, but regardless, there is no practical use to the answer, other than to cure my curiosity. Note this sentence at the end of the Artistic License 2.0: THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER AND CONTRIBUTORS "AS IS' AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES. It does not affect any legal aspects of the license, but is there a reason they mixed the use of single and double quotes on AS IS? The license is so new that this wouldn't have been for "command prompt friendly" reasons. Is there special use or meaning behind this in the English language, or was it a typo?

• What should I do with my programming project?

  - by rambodash

  I've been working on a top secret project that has potential of becoming very popular. No one has done anything like it. The problem is I have no motivation to finish it, and its about 70% done. I also don't have the ability to sell & market the product. The documentation is a pain to write. I just want to finish the project , receive my reward and move on to other things. I know that if I were to release it as a product I'm going to have to do support, and do bug fixes. No thank you! I've thought of making it open source but I'm failing to see the benefits. My hard work is just going to be up for grabs isn't it? How can I abandon my project whilst getting rewarded for the work I've done so far?
