An application I'm writing is using code/libraries that are licensed under free software licenses; specifically I have code that is licensed under the Apache License V2, GNU GPL V2, and the CPOL V1.02. From what I understand, if the customer request it, I would have to provide them with the source code under the free software licenses, but I don't want to provide the source code for my entire application.
My question is, if I take the three pieces of source code covered under the free software licenses and place them in individual libraries (DLLs) could I then apply a custom (proprietary) license to the rest of my application? This way if someone request the source code under one of the three free software licenses, I can provide the source code just for that library without having to release the source code for the rest of my application.
Would this be appropriate and inline with the license requirements of the free software licenses? Keep in mind that I'm not marketing my software as a free software/open source, but would like to use these libraries and be in compliance with their licenses.
Thanks in advance for any help and/or clarification you can provide. I've read over the licenses several times (as well as articles on them) and I;m still a little confused over the requirements as it applies to using it in closed commercial software.

Let's say that I would like to sell an application that uses some open source code inside.
The open source definition says that "the program must include source code". http://opensource.org/docs/osd[^]
However, the open source FAQ says that if the source code isn't distributed, then the license does not even apply to that situation. http://opensource.org/faq#non-distribution[^]
Except, in some circumstances, the source code has to be made available. What circumstances? I'm confused...
|
|
|
|
|
The FAQ is quite clear: If you don't distribute source code, then what you are distributing cannot meaningfully be called "Open Source". So you cannot claim it to be open source if you do not make all the source code freely available.
One of these days I'm going to think of a really clever signature.

It is not necessary to publish the source code. But when someone who bought your solution asks for the source code, you have to provide it to him.
Better contact the authors of the code you use and get a different license from them, or find source code which is published under a different license.

BAs in my company use Word, Excel and Visio for requirements definition reasonably well. What are the key advantages and disadvantages of using a requirements tool instead?
|
|
|
|
|
Integration with project management and ease of collaboration with developers.
Also, when requirement are linked to "Work Items" that dev are working on, it is then easy to track the overall progress of a particular requirement..
Sometimes, when a developer is working on a certain item of the requirement, he can discover things that would prompt the change of the requirement (adapting it or enhencing it).

I'd say consolidation of sources of info leads to less chances of error and easier tracking.

Hi
I have a company based in the middle east. Jordan in exact. I tried to make something new, and yes we built a new technology. A new application builder that really will reduce the programming into 30 - 40 % comparing with the traditional programming.
The problem that we are in Jordan, a very poor country. Even we made a very good technology, but we now are out of cash.
So we think in selling the technology for other parties. So I am asking for advise how we can do that and who is the best choice for us to try to sell the technology for.
The technology is an application builder built using SQL 2008 & Silverlight. This link https://sites.google.com/site/hasanhalabi/oneclick-lightswitch is a comparison between it and the LightSwitch the application builder than Microsoft has built.
Looking for Advice from you.
Thanks in Advance.

Ah, you solved a problem, and now you're looking for someone one with the same problem.
Three out of five companies that I worked for created an in-house solution to create applications "fast". They all failed on the most common ground; a user who needs something customized.
If you need to survive, then simply ask for problems and promise to solve them. If you're looking to prosper, solve them well.
Sounds like you're the one expert in your field in that specific location. So, brag about it. Might not come naturally being a developer, but that's the field of marketing and I'm sure they could help out

Thanks Eddy
We barged about it for the last year. and yet nothing. The culture in my country looking for the things come from US and Europe. Even if the things made here is better, they will keep tell us it is a local software, we don't believe on it! Just because we are a local company no one is looking to take the product from us!
About the things the others failed to accomplished. I think we pass it, because we did not built the product for our own then we tried to sell it for others. From the first step we though of it and design it to be used by any developer. I don't say it is the end for the developers pain in programming, but it is one thing which can open a new path of programming.
Thanks

I know what you mean; there was an experiment that showed how ants would "efficiently" solve a problem. They didn't know they were supposed to behave this way, and acted natural - not only did they create a longer route to the food-source when challenged, the old and long route would still be used even after the ants discovered a shorter one. Humans act in the same way.

You have several options;
- prove that your products adds value by automating non-profit organizations for free. That doesn't only generate goodwill, it also gets your name around.
- get a free lightweight version out there, and get a user-base - if they get hooked on your product, they'll become religious fanatics that spread your product.
- get a face in the US; hire some kid, send him/her to the States, have them market a version of your product. Get a second student adventurer, and send him/her to Europe, Russia or China.
- don't stop developing. Escalate it; create a plugin mechanism and document the API, get people to write plugins.
- a lot of users have their data in the cloud; ask around how many people use GMail. Provide alternatives.
- keep presenting yourself as the local expert. Give free lectures at local schools, and remind people that you are indeed the leading local authority. Make sure they don't forget.

That would certainly raise a lot of questions with the visitors of this site.

If your software is really good then you don't have worry about selling it. You need to focus on marketing.
“Doing business without advertising is like winking at a girl in the dark. You know what you are doing but nobody else does.”
― Steuart Henderson Britt, Marketing Management and Administrative Action
The product should be showcased and if it's worth then people will contact you. All you have to prove is how your product is value added to the business and provides a definite ROI.

Dear developers,
I just finished my project (outlook 2007 addin) and it is ready for deployment.
Unfortunately, I don’t know how to Determine the Right Price for it that is because the price should be a function of the costs and practically maintenance.
Can someone please list the maintenance costs of an application?
I have difficulties particular in the ratio of tech support per user (maintenance costs)
Tanks

How can anyone other than the developer know this? Maintenance cost is a function of the complexity of the app and the number of support people required, multiplied by the number of customers who need help. Almost impossible to guess in advance.
The price for your app can also only be determined by you as a function of the devlopment cost, the number of users, and the time period in which you hope to recover your costs. You also need to pitch it not too far above the competition unless you are certain that it's a killer app that will sweep the board.

Tanks,
Yes you are right, I now the complexity of my application but I thought maybe there is
A discussion on the subject that list more costs that I didn’t though about
And case studies in order to forecast it better and maybe make changes now before Deployment involves simple maintenance in the future.
Do you know more?
Tanks,
Patrick

It depends on which model you develop within.
A) If this is a project developed on request:
1) Hourly rates (development, test phase) X developers + server cost + adm. time
2) Fixed cost. Stipulated estimate of 1). Add some slack for unseen costs/time.
In addition segment the total cost by development, operation and maintenance.
Hourly rate is based on market price + adjustments for how good you are/experience and your market value in general (a well known company will be more expensive than a new established one).
B) If this a volume project for the market:
1) Your net cost (time, marketing, rent etc.) / estimated sold units + provision.
2) Competitive: What do your competitors price their similar product at?
In addition you could choose sub-models such as subscription, upgrades etc.
As always, there are different risks involved, especially with model B.
Hope this will give you a starting point.

I suppose that depends upon the type of app, the customer base etc.
Our company develops a app for a small group of customers. They yearly pay a fixed perc of the initial prize to get support. If they have additional wishes, they have to pay additional per hour or fixedprice.
A new (custom)module is prized the same way: they buy it, normally fixed prize, and the support prize per year rises with the same perc.
The prize for the module is based upon investment in resources plus a risk margin and sometimes devided by the number of clients we know that will buy it.
I don't know how TotalCommander does it, but they charge only once, and give updates for free.
They probably have a very big userbase.

You have to determine the pricing model first that you want to do, for example a one time fee or a subscription service. It is a great question but not one anyone else can answer. You have to have a feel for what the market is willing to pay. You have to decide.
There are only 10 types of people in the world, those who understand binary and those who don't.

As for maintenance, you should know best how much does it cost you.
Other indicator for the price is the competition. Are there other apps like yours? How big is the need for your app, etc.

Depends on
1.Efforts for implementation
2.If you are implementing as project then price should be more depend on point 1
3.IF you are implementing as product then it depends on your market penetrating strategy which covers point 1 as well as marketing ,support . it also requires consideration in making enhancement in product as per its market type
|
|
|
|
|
It all depends on tons of factors:
1. how many time you've spent doing it.
2. how many units you expect to sell.
3. how many maintenance you expect that will need to give.
4. the basic cost of your company per year.
...
A good way to start (probably) would be to see how your competitors are billing it and try to see how many of your previous "expects" would be acceptable.
Typically you will have to set a sales target...
Cross fingers and good luck!
