I have used a lot of opensource libraries. If I want to sell my software should i give royalties to those lib?

In general you are not obliged to give away royalties in the sense that whatever is your source it will continue to be yours. This means that you hold the credit for your own code. What else you can keep depends on the specific license of each library you use in your project. Most open source licenses will dictate that whenever you distribute your application you should make the sources for the dependency libraries available to your client. Some dictate that your own sources should be available as well. Some other licenses won't allow you to distribute your application commercially unless you pay for the library you used.\nIn brief read the license that comes with each library you used carefully it should be clear what you must, can, or can't do.

Everything depends on your record in the market. Have you done this before? What were the results? You will have to sell your services to a publishing house and an author and the book stores. What experience do you have in publicizing events. I don't mean to be rough but these are just some of the questions you will be asked. The people won't even talk price until you have a track record. I am a published author and still deal with this.

I use hotscripts.com for a large majority of the stuff that I design. Some of the scripts are paid, but most of the scripts are open source and free..........

As long as you do not redistribute it you are legal.  You may have limited redistribution rights under the "fair use" doctrine.  See an attorney for advice on that as it can be a legal minefield.\n\nMany streams are hard to capture but it's not illegal to do so in most cases.  As long as you're not breaking encryption to do so you should be OK.

You wont be able to make much off the laptop when you sell it. maybe a couple hundred bucks, depending on what kind it is and how very new it is, but technology moves so fast these days, its probably behind the times,  you know? i say keep it, its good to have at least when you CAN get it working.

No.  You can sell them as a resource guide.  You can only get into trouble if you somehow claim any sort of affiliation to the sites you list.  Be sure to include a disclaimer and state the purpose for the sale of these hyperlinks.  This way, you can defend yourself simply should someone give you any trouble.  Good luck.

Search Google for P2P software. That itself is legal. What you do with the software is YOUR responsibility.

There are actually two items up for bids here.  First is the domain name.  If you purchased it in your name then you are free to do with it whatever you like.  Where it gets tricky is the current content of your site.  If the content was developed by you and you copyrighted it then you can sell the site domain and content as a package.  However if the content comes from other sources then you really only have a claim on selling the domain.\n\nThere are a few sites set up to help you sell websites.  I've linked some below.

Anything that is not copyrighted. Open source software.

The problem with this is, if any money is generated in any way from what you are doing, you are infringing on the copywrite.  That includes if you are using say google to host your website and google sells advertising space on your website (like they do).  The person who is liable is you, not google.

No, I wait a long, long time to upgrade software.  There's no point unless it contains functionality that you don't have (or you need it for clients) and it is a bad idea in the first year or 2 of any major new software release, because of the possibility of bugs.
