I would not get the postings, which would indeed "piss me off". 3. The Minix Centre could almost certainly get the postings by buying a fast modem and spending a little money. One service these people provide is to pass on all the goodies to people, mostly computer amatuers, without network access. While I'm concerned that they may be making a little to much money out of this it would be a shame if the service vanished completely. As an alternative, how about somebody offering to send out postings regularly on floppies for a nominal handling charge?

However, since they do not receive any external support or funding, they are forced to get the money by selling some related products for a small profit. For that little amount of extra money, customers receive what they deserve: a decent service regarding system updates, and a place to go to in case of questions and/or problems. In my opinion, this is a very fair deal for most people. Tony: As the founder of the MINIX User Group Holland (NLMUG), and co-founder of a number of other MUGs in the world, and as the primary founder of the MUGNET MINIX Network, which are all recognized non-profit organizations, I am "shocked" by this message. > Several things disturb me about this. Firstly does this company > have permission from Prentice Hall for what they are doing? 1. Yes, ANYONE may sell MINIX for profit AT ANY PRICE. If you buy a copy of the Acme Word Processor program for $100,-, you may sell it to anyone for any price. If the buyer pays you more than what YOU payed for it, then he is real dumb, and you just made a profit. If the guy pays less, then you'll be losing money. Since I am the official MINIX distributor for the Netherlands (personally, not the NLMUG !), I can place ads like the one above as well. However, Prentice-Hall sometimes appoints certain companies or orga- nizations as "official" Prentice-Hall dealers for MINIX related stuff, since MINIX is hard to obtain in some countries. TMC is one of them in the UK, and I (personally, not NLMUG) is one of them in the Netherlands. This, of course, offers some nice quantity discounts. However, one must also "promise" to promote the MINIX product at best. > Secondly they are selling the contents of this newsgroup for profit. The 2. My (official !!) Prentice-Hall price book says: MINIX 1.3 Disks (AT and XT) UKP 98.44 US$ 113.15 MINIX 1.1 ST Disks + Man. UKP 98.44 US$ 113.15 ... Since all dealers get some amount of discount, "The MINIX Centre" can sell MINIX for any price they want to, as long as it is higher than what they had to pay for it (I know what their discount rate is, amd I can only tell you that is a fair one.) It would be silly to say that they do not make a profit of selling MINIX packages to people inside the UK, but remember that TMC does this as a means to keep the organization going. I know the guys behind TMC (I am sure they will read this, so they probably will reply to it...), and they already explained to me (and, no doubt, to many others) that they have to get some money to keep the MINIX services alive, since they do NOT have members, nor do they get any funding from universities and the like. As long as people put no (c)opyright on posted material, this can be included in any MINIX-package, provided that it is labelled as such. However, the price may not be raised due to the addition of the USENET material. In other words: they sell MINIX for profit (to keep the organization going), and add interesting USENET stuff to the packages being sold, for the customer's convienience. They do not (yet) have access to MUGNET, so they are unable to offer these articles in any other way, like a BBS system, for example. > trouble is I don't see any way to stop them. 3.

PD libraries are allowed to make a "reasonable charge" for conveying software, such as cost of postage, disk, cost of running the company, etc. If they are charging more than this then they are breaking the law. I don't know whether this is criminal law (the police get involved) or civil law. Judging by most other PD libraries, the cost of the disks should be no more than about \(ps 5 / $10 (although it might justifiably be more if the customer base is much smaller). I'd rather have this service around than not - there are a lot of minix users without access to USENET, and who need the information (I used to be without USENET access, and it really _hurt_ - one of the factors in my job change!).

I don't mind that situation either; what I _do_ mind if I post / publish some code to the public domain, then someone else comes and (perhaps improving the code somewhat, perhaps deleting my name, perhaps omiting documentation and source, perhaps doing something else) starts selling the code so that the buyer of that program isn't allowed to redistribute. I think Minix is a very good service to the community, but I see some of the above scene happening with Minix (or perhaps it's my misunderstanding). I think there's a lot of user-contribued stuff distributed with Minix. The authors have allowed free use of that stuff, fine. But I suppose all the software in Minix comes with Prentice-Hall copyright, so you aren't allowed to redistribute that free stuff, either, if you got it with Minix, right ? Please tell me I'm wrong. That's what I think is a very good aspect of the GNU copyright. It guarantees all the users / redistributers the right to get _everything_ of the original work easily and takes away the possibility of a third party taking this freedom away. For these reasons, if I'll make some sizable contributions to Minix (or any other effort-taking software development for that matter), I'll probably put them under the GNU copyright. This may mean that Prentice-Hall won't put them in the official distribution, but the improvements (if they're not too much dependent on Minix) are available for use by free software developers easily, ie. someone can port them to GNU OS or something else to be freely distributable. If I just give them to the public domain, it easily happens that someone takes the software and restricts it's redistribution (like happens currently with X, TeX, Scribe (if I remember right), Ingres, Berkeley version of Unix etc.) //Jyrki

Please tell me >I'm wrong. Hmm. I'm not a lawyer, but I think PH only holds copyright to part of the sources, and a compilation copyright to the rest of the stuff. If you contribute a program with a copyright notice allowing unlimited distribution, PH will surely respect it, and people can take it off the MINIX disks without any problems (my opinion/interpretation). However, if the wording is very strictly and there is a possible implication that it also has effect on the other MINIX stuff it is probably rejected. The stuff on the MINIX disks is the same stuff that is posted by ast. Part of the utilities carries copyright notices of other people or institutions. For instance look at the code or more(1). I think that you can take the more sources from the MINIX disks, and do with it whatever you want as long as you comply with the copyright notice in more.c Sometimes I speak for me. Sometimes not.

If you post a program and put in an explicit message that it is in the public domain, then no one can get it out of the public domain. Anyone can modify it (even a single character) and then copyright the modified version and prevent anyone from using THAT version, but the original remains in the public domain. Once pubic domain, always public domain. I would suggest that people who post software and intend it to be in the public domain, put in a notice to that effect. That way people who want to sell it (e.g. P-H) can do so, but they cannot prevent anyone else from doing what they want, including giving it away free. The GNU copyleft, which creates legal obligations on the part of anyone selling it, causes lawyers to go into infinite loops. Statements that something is simultaneously copyright and public domain (see du.c) make as much sense as the law passed by the Indiana State Legislature around 1890 saying that in Indiana pi was legally exactly 3.0.

In general, this is not merely a good idea, it is necessary. In countries abiding by the Berne Convention -- which now includes the US -- it is not necessary to attach a copyright notice for copyright to be in effect. If you want something to be in the public domain, you *must* say so, in order to renounce the implicit copyright. Personally, I don't recommend putting things into PD. A nice permissive copyright notice like the Berkeley one or the C News one is better. That way, you can at least insist on getting credit for what you do.

Nope. When a work is in the public domain, anyone can do anything he wants with it, including modifying it, selling it for an abitrary price, and much more. The only thing he can't do is get it out of the public domain. This discussion of the law is getting a bit weary. For people who want to discuss copyright, public domain, and related issues, I strong recommend the following book (written by 3 ACLU lawyers): Title: The Rights of Authors and Artists Authors:K.P. Norwick, J.S. Chasen with H.R. Kaufman Publ: Bantam Books, 666 Fifth Ave, New York, N.Y. 10103 ISBN: 0-553-23654-7 Price: $3.95 It is only 200 pages and written for nonlawyers, but it explains everyone you every wanted to know about copyright law, libel, and fun things like that. A lot of what is said in this and other groups about the law just ain't so. The book tends to examine things from a civil liberties point of view (like the question of whether the statement: "All Lithuanians are child molesters" in a book would be libel under the law), but it also discusses the copyright law in considerable detail.

If you release your software into the public domain, nobody, not even the original author, can ever prevent anyone from using it in any way, ever. If that is your intention, then a statement simply putting the code into the public domain is enough. The GNU copyleft has a very serious problem of creating legal obligations on the part of anyone using it. I have very carefully avoided using any GNU software in MINIX as well as in Amoeba, even though technically I might have been willing. Although the intention of copyleft may have been to make sure the software was always available to the public, for me it has had just the opposite effect. I can live with public domain and I can live with copyrighted software plus a statement in the code or in a side letter granting permission to use it, but a legal, enforceable obligation to do ANYTHING is going to make any lawyer, including P-H's, sit up and take notice. What exactly, have they contracted to do, what have they gotten in return, what record keeping do they have to maintain to defend a lawsuit, how much in damages might they be liable for, and more. It is anything but simple. Andy Tanenbaum (a...@cs.vu.nl)
