wecker@cookie.dec.com (DAVE CUM GRANO SALIS WECKER) (12/14/86)
I thought people might like this... it is a repost of Mike Meyer's clock
program with the following goodies:
1) It now works under Manx
2) It updates the display every 4 seconds UNLESS memory
usage is changing, then it updates every 1/4 second.
This means that even though it runs at high priority (20),
it stays out of the way unless there are interesting things
to monitor (in the way of memory usage).
3) I wrote my own "tiny" printf replacement [fmt()] so this
program is SMALL.
4) The display is centered and short enough that it can be
used with VT100 and not intefere with the top line of text.
5) I like it ;-)
Two side notes:
1. The memory usage numbers are in "k" (i.e., 1024 bytes) so
the shell MEM command and this won't appear to agree until
you divide the shell number by 1024 (not 1000).
2. This is the program I used to notice the bizarre copy behavior
to RAM: (double space usage). I am happy to note that it is
COMPLETELY fixed under 1.2 (yea 1.2 ! ! ! !).

Dave, in one posting, you've managed to: 1) Break the law. 2) Put *false* words in my mouth, and in so doing 3) Misrepresent my position on PD software. 4) Place my code in the public domain, when I hadn't done so. Let me quote from the initial comment of *MY* version of that program: /* * clock - a dumb, digital clock in the upper right-hand corner. Designed * to be small, not flexible! * * Copyright (c) 1986, Mike Meyer * * Permission is hereby granted to distribute this program for any purposes * whatsoever, so long as this notice, including the above copyright, is * included with the distribution. Unlike other people, I don't care if you * make money off of this, so long as I get credit for having written it. */ Now, let's see what's left of this in the version Dave posted: >/* clock - a dumb, digital clock in its own window > * > * original: Mike Meyer - public domain, not for sale > * v1.1: Dave Wecker - under Manx, auto change of timings, no printf > * > */ Firstly, my copyright notice has disappeared. Since permission to redistribute was granted ON THE CONDITION that it not disappear, you've broken the law. I'll concede that this is a shaky copyright notice, but that's not a good reason for doing what you did. Second, the words "public domain" and "not for resale" are incompatable. If something is not for resale, it can't be in the public domain. Likewise, if it's in the public domain, anyone can do whatever they wish with it, including compile it and sell the binaries as their own. Third, I specifically said that I don't care if other people resell the thing. You attached the "not for sale" to my name, implying that I said it. I would never say any such thing, as 1) it's not legally possible to do that, and 2) I disagree with the sentiments expressed. Finally, since you left off the copyright notice, failed to add your own, and distributed the code on a public network, you've placed it in the public domain. Thus anyone who wants to can legally compile it and sell the binaries, without every mentioning my name - or yours, for that matter. You obviously did a significant (compared to the work I originally put into it) amount of work on the code (you also left a construct in it that's illegal under ANSI C). There's a way to indicate this, and have your wish that it not be resold indicated, that is both legally and morally correct. Namely, you add your own copyright line, and then say "May not be sold, or included as part of any package which is sold." or words to that affect. We'd both hold copyright on the resulting program, and anyone who wished to do something with it under conditions other than those in the copyright notice would have to get in touch with both of us. Dave, this action is, as far as I'm concerned, indistinguishable from that of people who sell code that's marked "public domain, not for sale." True, you haven't made any money; but they haven't broken the law. The important thing in both cases is that you've violated the express wishes of the authors of the code. It's that kind of thing that makes people stop making programs publicly available. Dave, if you got a copy of the program from someone else who had stripped my copyright notice off, I apologize. I'm still P.O.'d, but don't know who did it. In that case, I'd appreciate help in finding the culprit, so I can properly vent my wrath at them. <mike

He hasn't done this...even though the copy was distributed without a notice, your copyright is still valid. All he could do is place his own code in public domain.

There's no such thing as "public domain, not for sale." Either it is Public Domain, which means any member of the public is free to do anything to it, including sell it, or it is copyrighted (possibly freely redistributable).

Mike,
I have inserted an effective message as to your intent, in
my copy (in case I sent it out). If you could post the copyright
notice so that the rest of us could do likewise, it would no doubt
be appreciated. I have no intention of purging source. I will
maintain your claim to fortune and glory (as is your right).
