- In Defense of Copy Protection
-
- No, I haven't lost my marbles. And no, I don't like copy
- protection either. But there IS more than one side to this
- issue, and I'd just like to point out a few facts for the
- other side.
-
- The major problem in this industry today is software piracy.
- It's been estimated that over half the copies of 1-2-3 in
- use by major corporations are pirate copies. Wordstar does
- even worse than that. One of my sources tells me of a major
- international corporation where almost every PC is equipped
- with a large assortment of pirated software, and the people
- using it see nothing wrong.
-
- I've lost count of how many times I've heard people complain
- that the software houses should "get rid of expensive copy
- protection and just price the stuff reasonably." I'm told
- that Lotus charges far too much for 1-2-3, and that if they
- only asked (figure varies, generally under a hundred bucks)
- then nobody would pirate it and they'd make more money.
-
- Bull chips. They could sell it for ten bucks a pop, and

-
- people would STILL pirate it. As for the price being
- unreasonable, I have news for you. The retail price of
- 1-2-3 would just about get you my services for ONE DAY, so
- think for a minute how much 1-2-3 would cost if you tried to
- get someone to write it for you.
-
- The upshot is that when a company does an honest piece of
- work and produces a quality piece of software, they deserve
- to make some bucks on it.

- NEWS
- ============================================================
- In view of the expansion of Fido, I would like to propose an
- idea for reduced-cost mail, involving low overhead on the
- part of each local board, and a LARGE overhead on the part
- of the network manager.
-
- Fido COULD send mail from local dialing area to local
- dialing area, but to do this would involve creating a graph
- containing all Fidos, each graph containing COMPLETE routing
- instructions for point-to-point transfer. At each receiving
- station, (pardon my LISP) take CAR(ROUTE-LIST) as the next
- node to transmit to, and send CDR(ROUTE-LIST) as the New
- ROUTE-LIST. Upon arrival at the desired point, CAR(ROUTE-
- LIST)=NIL, and the message has arrived at its final
- destination. The file sent could easily be small relative
- to ROUTE-LIST, and each Fido would have to store (#NODES)^2
- maximum ATOMS - this is a HUGE amount of disk overhead.
-
- The idea I would like to suggest would be that each FIDO
- store a route map for its LOCAL hub only, with designated
- Fido GATEWAYS to the next hub in the direction of travel.
- Each GATEWAY would have LOCAL numbers leading into a new
- hub, would check the final-destination address, and pass it
- to the next hub. The incoming gateway would then route to
- an appropriate gateway in its hub, or to its final
- destination if in the current hub.
-
- The biggest problem in this is the construction of the map -
- and what to do in the event of a GATEWAY FAILURE (i.e. the
- gateway is down or otherwise unable to pass messages).
- Adaptive routing would be nice, except that this involves a
- large communications overhead (each active node must
- periodically pass the list of LOCAL Fidos that it can
- actually contact to each GATEWAY in its hub.) My guess is
- that this would entail an additional 15-20 minutes per day
- (or mail period) in receiving and transmitting local connect
- information. If adaptive routing is not made automatic, one
- node would have to determine the map of local nodes and
- gateways, and go from there. Inter-hub linkages should be
- made redundant (i.e. if hub 1 wants to talk to hub 2, there
- should be more than one gateway to hub 2, if at all
- possible.)
-
- The message traffic bottleneck would come at the GATEWAYS -
- it would be essential that (1) the gateway have sufficient
- hard disk storage to hold all incoming or outgoing mail for
- the HUB!!! and (2) the gateway have the capability of
- reporting to the net the failure of another gateway, so that
- alternative routing can be generated. The mathematics
- involved in this part of the problem would be (1) topology
- and (2) graph theory. Andrew Tannenbaum's "Computer
- Networks" (Addison-Wesley, 1981) discusses these topics in
- relation to mainframe point-to-point networks (the examples
- are ARPANet and IBM's SNA), and discuss the possible
- solutions.

-
- I currently have a program which is used to solve this type
- of problem in a generic sense - it is a modification of DR's
- NETWORK2.PLI program. In order to use this program, it is
- necessary to construct an exhaustive list of the local
- dialing area overlap relative to FIDO nodes. This program
- as presently written is memory bound - I do not think that
- the mapping for a 1000 node system could be stored in less
- than 384K on a PC under PC-DOS 2.1 (we run the program on
- the CompuPro here in house to solve LAN gateway problems.)
-
- Under Fido version 10i, the point-to-point could only be
- handled within a local hub - there are two main reasons that
- it would be difficult to use for other purposes:
-
- (1) There is no provision in the FidoMail to place more
- than a total of two destinations for a file - the first is a
- transmit-to address for an incoming gateway, the second
- being the final distribution address. This would make it
- possible to make a two-jump transfer - transmit to an
- incoming during National Mail, and then redistribute during
- a local mail period. This would be practical for messages
- between, say, New Haven and Bridgeport, with an incoming
- station in Milford.
-
- (2) The amount of time it would take to make a long
- distance trip would be prohibitive. Suppose that using
- local-to-local jumps, you could have a message make three
- jumps per day - about 50-70 miles. It would take about 40
- days to get to a destination in California!!! Also,
- discontinuities would exist between many locations - those
- locations would be unreachable under the FREEMAIL concept.
- In the event of a gateway failure, either a new FREEMAIL
- route would be needed (adaptive routing), or the mail would
- be further delayed - possibly forever if the gateway remains
- down.
